the following description concerns preferred embodiments of the waste plastic to fuel oil converting distillation vessel . the waste plastic to fuel oil converting distillation vessel disclosed herein can be interchangeably referred to as a vessel , reactor , distillation vessel , reaction vessel , or the like . as shown in fig1 , a preferred embodiment of the present invention includes a reaction vessel 3 . the reaction vessel 3 has a wall , preferably a cone - shaped wall or a cylindrically shaped wall , which makes up its body . the wall extends between a first and a second end of the vessel and the vessel 3 has a total length of up to 24 feet , preferably about 15 - 21 feet . the first and second ends of the vessel can be configured to any suitable operating diameters although in a preferred embodiment , the diameter of the second end is in a range of from about 72 - 144 inches . furthermore , the reaction vessel 3 can be made from any suitable material that can handle the high temperatures that the vessel is exposed to , such as iron , an alloy steel , and the like . the reaction vessel 3 may also be housed inside of a kiln structure 27 ( shown in fig5 and 6 ). fig3 shows a feed - in entrance 21 protruding through the first end of the reaction vessel 3 . the feed - in entrance 21 can be connected to an automatic hydraulic feeder ( not shown ) or any other known method to perform feeding or continuous feeding of the waste plastic or rubber . moreover , the feed - in entrance 21 can be situated on or engaged with , and supported by , a support bearing 26 . at the second end of the reaction vessel 3 , a residue discharge outlet 4 is shown protruding therethrough . the residue discharge outlet 4 can also be referred to as a curved tube . an oil or gas output tube 24 is also shown protruding through the second end of the vessel 3 . the oil or gas output tube 24 or fuel output tube 24 can have a helix thruster 25 and a filter ( not shown ) disposed therein . also , the oil or gas output tube 24 can be situated on or engaged with , and supported by , a support bearing 26 . a shield 23 is placed inside of the vessel 3 near an entrance of the oil or gas output tube 24 to block unwanted residue from escaping through this tube . if the unwanted residue were to get into the oil or gas output tube 24 , the helix thruster 25 set in the tube can push the residue back into the vessel 3 . the shield 23 , feed - in entrance 21 , residue discharge outlet 4 , oil or gas output tube 24 , helix thruster 25 , and support bearings 26 can be made from any suitable materials that can handle the operating temperatures of the vessel 3 , such as iron , an alloy steel , and the like . a plurality of supporting tubes 22 are housed inside of the reaction vessel 3 wherein the supporting tubes 22 protrude through the wall of the reaction vessel 3 and open out . these supporting tubes 22 can be arranged horizontally , vertically , diagonally , and any combination thereof inside of the vessel 3 . the quantity of supporting tubes 22 used depends upon the length of the reaction vessel 3 where a longer vessel 3 could require more supporting tubes 22 . each end of the supporting tubes 22 goes through the vessel wall and opens out so heated air or gas can be supplied therethrough . when the vessel 3 is housed inside of a kiln structure 27 , the air or gas inside of the kiln 27 is heated and in turn , heats the vessel and flows through the open ends of the supporting tubes 22 to heat them as well . with the supporting tubes 22 going through the vessel 3 , the waste plastic or rubber therein is evenly heated and the reaction vessel 3 is capable of achieving much higher operating temperatures than a vessel 3 not including the supporting tubes 22 . the supporting tubes 22 can have any suitable diameter , preferably a diameter of up to 200 mm , and be made from any material that can withstand the operating temperatures that the vessel 3 is exposed to such as seamless steel , an alloy steel , iron , and the like . as a result of the placement of the supporting tubes 22 inside of the reaction vessel 3 , the strength of the vessel 3 is greatly improved . due to the high temperatures that can be achieved inside of the vessel 3 , such as 450 ° c ., and outside of the vessel 3 , such as 800 ° c ., the shape of the vessel 3 could easily become distorted as it does with the vessels in the prior art . however , the vessel 3 of the present invention is not subjected to the shape distortion problems associated with the prior art reaction vessels at least because of the supporting tubes 22 of the present invention . also due to the supporting tubes 22 , the first and second ends of the vessel 3 can have a much larger diameter than those found in the prior art so the vessel is capable of handling the demand of large - scale manufacturing . moreover , the life of the vessel 3 is greatly increased due to the supporting tubes 22 . finally , the supporting tubes 22 allow the waste plastic or rubber to be heated evenly inside of the vessel 3 , which causes a complete reaction of all of the waste plastic or rubber into vapor . in a preferred embodiment of the present invention , the reaction vessel 3 further includes a rotation mechanism . the rotation mechanism allows the vessel 3 to continuously rotate , preferably about the center longitudinal axis , during operation . the rotation mechanism can include a motor that supplies power and facilitates rotation of a first and a second gear ( not shown ), whereby rotation of the first and second gears allows rotation of the vessel 3 . in a preferred embodiment , the second gear is provided on the vessel 3 , preferably the feed - in entrance 21 comprises the second gear , so that rotation of the first and second gears facilitates rotation of the reaction vessel 3 . although the rotation mechanism can comprise a motor , and a first and second gear , various other rotation mechanisms can be used , such as pulleys , magnets and the like , in accordance with the present invention as is commonly known by those skilled in the art . the vessel 3 of the present invention can be used in a method of converting waste plastic or rubber into fuel oil . the method may include any or all of the following steps , not necessarily in the order as described . a motor is activated whereby the motor facilitates rotation of a first and a second gear , wherein the second gear is provided on the reaction vessel 3 , causing the reaction vessel 3 to rotate . waste plastic or rubber and a catalyst are then manually or automatically fed through the feed - in entrance 21 . the catalyst can be alumina based , silicon dioxide based , or any other catalyst useful in method of converting waste plastic or rubber into fuel oil . the reaction vessel 3 and the supporting tubes 22 are then heated . an operating temperature of up to 800 ° c ., and preferably about 700 ° c ., can be achieved outside of the vessel 3 . moreover , the inside of the vessel can be heated to a temperature of about 400 ° c . to 450 ° c . such a high operating temperature inside of the vessel 3 is attributable to the supporting tubes 22 incorporated in the vessel 3 , and a vessel not including these supporting tubes 22 would not be capable of achieving such high temperatures . the waste plastic or rubber is then transformed from a solid to a liquid state with the increasing temperature . the liquid is then converted into a gas or vapor phase under the action of the catalyst and the waste plastic or rubber vapor flows through the oil or gas output tube 24 and exits the vessel 3 . this vapor is then condensed into a mixture of liquid hydrocarbons in a condenser ( not shown ), before which the dust impurities carried by the vapor are separated in a settler ( not shown ). the condensate is then transmitted from the condenser through an oil - water separator ( not shown ) to obtain an oil phase product . the oil phase product is then brought into a mixing tank ( not shown ) and the catalyst is added to the mixing tank to improve the stability of the oil phase product against oxidation . finally , the oil phase product is refined to produce gasoline , diesel oil , or other hydrocarbon fractions . a preferred embodiment of the vessel 3 incorporating a continuous residue discharging system will now be described . with respect to fig2 , a high temperature , separable , continuous residue discharging system includes two sub - systems : a first residue discharging system and a second residue discharging system . the first residue discharging system is assembled in a reactor 3 . the reactor 3 can be any type of reactor that converts plastic , rubber , industrial waste or the like into oil , fuel , or the like . the first residue discharging system is a three unilateral shaft conveyer system . however , the system may include only one shaft or any number of shafts depending on the diameter of the shafts and the size of the reactor that the shafts are housed inside of . in the embodiment shown in fig2 , the driver shaft 16 of the conveyor system extends the length of the reactor 3 and further into a residue discharge outlet or curved tube 4 ( as shown in fig1 ). a spiral vane 17 is disposed on the driver shaft 16 . the curved tube 4 includes a flange 5 , which connects the curved tube 4 to a first tube 10 . the first tube 10 has the ability to retract from the connection with the curved tube 4 . also shown in fig1 is the first tube 10 as it connects to the second tube 9 . in a preferred embodiment , the second tube 9 is made of steel and has a diameter of 325 mm but this tube can be made from a variety of materials known in the art and include a large range of diameter sizes . furthermore , the second tube 9 can be an integral , single body tube or it can comprise multiple segments that are connected together to form a pathway . the second tube 9 is further attached to a residue storage tank 20 . the connection of the curved tube 4 by its flange 5 to the first tube 10 , the first tube 10 to the second tube 9 , and the second tube 9 to the residue storage tank 20 forms a closed residue discharging channel . housed inside of the second tube 9 is a second residue discharging system . as shown in fig1 , the second residue discharging system includes a single driver shaft 7 with a spiral vane 8 disposed thereon . the spiral vane 8 can be located in between a pair of bearing components ( not shown ), which support the single driver shaft 7 and allow it to rotate smoothly . however , in other embodiments , the second residue discharging system can include any number of shafts . also depicted in fig1 and 2 are the sources used to power the system . a first power source 1 delivers power , through a clutch 2 , to the driver shaft 16 of the first residue discharging system . the second power source 6 is also shown . this power source delivers power to the single driver shaft 7 of the second residue discharging system . the power sources 1 , 6 can include an engine and a decelerator . as shown in fig1 , a preferred embodiment of the first residue discharging system includes a three unilateral shaft conveyor system housed in a reactor 3 . the driver shaft 16 is shown as well as a first driven shaft 13 and a second driven shaft 18 . the first and second driven shafts 13 , 18 include residue collecting vanes 14 disposed thereon . the driver shaft 16 includes a spiral vane 8 disposed thereon . these vanes 8 , 14 assist in the residue collection and conveying process by moving the residue from the reactor 3 into the curved tube 4 . the shafts 13 , 16 , 18 of the first residue discharging system are supported at both of their ends by bearing components 12 . the bearing components 12 allow for smooth rotation of each shaft 13 , 16 , 18 . also shown ( but not labeled ) is the curved tube 4 and the driver shaft 16 is extending therethrough . the driver shaft 16 includes a driver gear that is engaged with a first gear of the first driven shaft 13 and a second gear of the second driven shaft 18 . all of these gears are housed inside of a gear case 11 . while the reaction vessel 3 is still at extremely high operating temperatures , the closed residue discharging channel can be formed as previously described and the residue can be discharged from the vessel 3 . accordingly , as shown in fig1 and 2 , the first tube 10 is connected to the flange 5 on the curved tube 4 . the first power source 1 is activated and transfers power , through the clutch 2 , to the driver shaft 16 . the second power source 6 is also activated and it transfers power to the single driver shaft 7 . as power is transferred to these shafts 7 , 16 they begin to rotate . rotation is smooth because the shafts 7 , 16 are supported on bearing components 12 . as the driver shaft 16 begins to rotate , its driver gear rotates causing the first and second gears of the first and second driven shafts 13 , 18 to rotate , which in turn , causes the first and second driven shafts 13 , 18 to rotate . the residue collecting vanes 14 disposed on the first and second driven shafts 13 , 18 and the spiral vane 8 disposed on the driver shaft 16 collect residue from inside of the reactor 3 and as rotation of the vanes 8 , 14 occurs , residue is pushed or conveyed towards the curved tube 4 . since the driver shaft 16 and the spiral vane 8 disposed thereon extend through the curved tube 4 , the residue is pushed into the curved tube and falls down , through the first tube 10 and into the second tube 9 . once the residue falls into the second tube 9 , the spiral vane 8 on the rotating single driver shaft 7 begins to push or convey the residue towards the residue storage tank 20 . once all of the high temperature , combustible residue has been transferred from the reactor 3 to the residue storage tank 20 , the power sources 1 , 6 are deactivated , the clutch 2 is disengaged which will disconnect the first power source 1 and the driver shaft 16 , and the first tube 10 is retracted from the flange 5 . fig5 shows a preferred embodiment of the present invention wherein the reactor 3 is housed inside of a kiln 27 . under the reactor 3 and inside the kiln 27 is a heat insulation wall 28 . the heated air inside of the kiln 27 can circulate around the reactor 3 and evenly heat it . the kiln 27 and heat insulation wall 28 can be made of fire brick . the heater 29 is also shown in fig5 . the heater 29 heats the air or gas inside of the kiln 27 and , in turn , heats the vessel 3 and supporting tubes 22 . however , in an embodiment that does not include a kiln 27 , the heater 29 simply heats the vessel 3 and supporting tubes 22 . the heater 29 may operate by the combustion of a fuel , such as fuel oil or natural gas . it should be understood that other heaters commonly known in the art , such as an electric heater , can be used to heat the reaction vessel and supporting tubes . depicted in fig6 is the reactor 3 housed inside of the kiln 27 . the heater 29 heats the air or gas inside of the kiln 27 . in turn , the reactor 3 , supporting tubes 22 , and the heat insulation wall 28 are heated . the heated air or gas can circulate around the reactor 3 as shown by the arrows in fig6 and also flow through the supporting tubes 22 . from the foregoing , it is believed that one of skill in the art will readily recognize and appreciate the novel advancement of this invention over the prior art and will understand that while the same has been described herein and associated with preferred illustrated embodiments thereof , the same is nevertheless susceptible to variation , modification and substitution of equivalents without departing from the spirit and scope of the invention which is intended to be unlimited by the foregoing except as may appear in the following appended claims .
