Revolving waste plastic-oil converting equipment and method of using the same

Abstract

A waste plastic to fuel oil distillation vessel is disclosed. The distillation vessel can be a revolving cone with many traverse supporting tubes therein. This structure allows high temperature air or gas to go through the support tubes, which pass through the vessel, to increase the heating area and increase the temperature of the distillation vessel. Also disclosed is a discharging system for discharging residue from inside of the vessel and a method of converting waste plastic or rubber into fuel oil.

1 . A device for converting waste plastic or rubber into fuel oil, the device comprising:
 a vessel having a wall extending between a first end and a second end of the vessel;   a feed-in entrance protruding through the first end of the vessel;   a residue discharge outlet protruding through the second end of the vessel;   a fuel output tube protruding through the second end of the vessel; and   a plurality of supporting tubes housed inside of the vessel wherein the supporting tubes protrude through the wall of the vessel and open out.   
   
   
       2 . The device of  claim 1 , wherein the wall is cone shaped. 
   
   
       3 . The device of  claim 1 , further comprising a kiln in which the vessel is housed. 
   
   
       4 . The device of  claim 1 , further comprising a rotation mechanism. 
   
   
       5 . The device of  claim 1 , further comprising a first support bearing on which the feed-in entrance is supported. 
   
   
       6 . The device of  claim 1 , wherein the supporting tubes are arranged in a manner selected from the group consisting of vertically, horizontally, diagonally, and any combination thereof. 
   
   
       7 . The device of  claim 1 , further comprising a shield housed inside of the vessel in front of the fuel output tube. 
   
   
       8 . The device of  claim 1 , further comprising a second support bearing on which the fuel output tube is supported. 
   
   
       9 . The device of  claim 1 , further comprising a heater. 
   
   
       10 . The device of  claim 1 , further comprising a helix thruster housed inside of the fuel output tube. 
   
   
       11 . The device of  claim 3 , wherein air or gas inside of the kiln is heated, thereby flowing through the supporting tubes and heating the supporting tubes and vessel. 
   
   
       12 . The device of  claim 1 , further including a filter in the fuel output tube. 
   
   
       13 . The device of  claim 1 , further comprising a discharging system housed therein. 
   
   
       14 . The device of  claim 13 , wherein the discharging system further comprises a first residue discharging system housed inside of the vessel;
 the residue discharge outlet further comprising a flange connectable to a first tube;   the first tube being connectable to a second tube;   the second tube being further connectable to a residue storage tank;   a second residue discharging system housed inside of the second tube;   wherein a closed residue discharging channel is formed between the first residue discharging system and the second residue discharging system.   
   
   
       15 . The device of  claim 14 , wherein the first residue discharging system further comprises a three shaft conveyor system including a driver shaft and a first and second driven shaft, each shaft being supported by one or more sliding bearings. 
   
   
       16 . The device of  claim 14 , wherein the second residue discharging system comprises a single driver shaft conveyor system supported by one or more bearings and having a spiral vane disposed thereon. 
   
   
       17 . A method of converting waste plastic or rubber into fuel oil comprising the steps of:
 providing a device comprising a vessel having a wall extending between a first and a second end;   providing a feed-in entrance protruding through the first end of the vessel;   providing a residue discharge outlet protruding through the second end of the vessel;   providing a fuel output tube protruding through the second end of the vessel;   providing a plurality of supporting tubes housed inside of the vessel wherein the supporting tubes protrude through the wall of the vessel and open out;   rotating the vessel;   feeding waste plastic and/or rubber and a catalyst through the feed-in entrance;   heating the vessel and supporting tubes to vaporize the waste plastic and/or rubber whereby the waste plastic and/or rubber vapor flows through the fuel output tube;   cooling the waste plastic or rubber vapor to form a condensate;   transmitting the condensate from the condenser through an oil-water separator to obtain an oil phase product.   
   
   
       18 . The method of  claim 17 , further comprising the step of housing the vessel inside of a kiln. 
   
   
       19 . The method of  claim 17 , further comprising the step of providing a shield inside of the vessel in front of the fuel output tube. 
   
   
       20 . The method of  claim 17 , further comprising the step of providing a helix thruster inside of the fuel output tube.
