[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the interplay between an explosion-proof motor, a spiral stirring plate, a cylinder, and a vessel body to achieve the following: The explosion-proof motor starts, drives a crossbar to rotate, which in turn drives a rotating rod to rotate. The rotating rod then drives the spiral stirring plate to rotate. The rotating rod, via a second T-block, drives a movable column to rotate. The movable column, through a crossbar, drives a connecting column to rotate. The connecting column, through a first T-block, drives an L-shaped polishing plate to rotate. The L-shaped polishing plate polishes the inner wall of the vessel. While the L-shaped polishing plate is rotating, the movable rod is moved upwards in advance to move the float to the top of the L-shaped polishing plate. The special oil is then poured into the reactor body through an L-shaped tube. After the oil is poured in, it causes the float to move upward, which in turn causes the movable rod to move upward. The movable rod then causes the limiting plate to move upward, exposing the scale on the movable rod, allowing the volume of the special oil to be determined. Simultaneously, the oil causes the float plate to move upward, which in turn causes the movable column to move upward. The movable column then causes the cross plate, connecting column, and first T-block to move upward, and the movable column causes the second T-block to move upward. The second T-block then moves from the first T-slot into the T-shaped annular groove. The explosion-proof motor is then activated, causing the spiral stirring plate and the fixed stirring plate to rotate. The spiral stirring plate and the fixed stirring plate stir the special oil, while the heat-conducting fins heat the oil. After processing is completed, open the discharge valve to discharge the processed special oil. If it is necessary to clean the inside of the reactor, first turn the second bolt to remove it from the first and second fixing rings, thereby disassembling the explosion-proof motor. Then turn the first bolt and start the cylinder. The cylinder drives the second flange and cover plate to move upward. The cover plate will drive the rotating rod and L-shaped polishing plate to move upward. When the connecting plate is away from the L-shaped plates on the front and rear sides, turn the cylinder to the rear. The cylinder drives the crossbar to rotate, thereby removing the rotating rod and L-shaped polishing plate from the inside of the reactor. Then clean the inner wall of the reactor, the spiral stirring plate and the fixed stirring plate. Turn the third bolt to disassemble the heat-conducting fins. Attached Figure Description

[0016] Working principle: Before the device starts working, the explosion-proof motor 18 is started. The explosion-proof motor 18 drives the transmission rod 19 to rotate, the transmission rod 19 drives the cross rod 20 to rotate, the cross rod 20 drives the rotating rod 13 to rotate, the rotating rod 13 drives the spiral stirring plate 14 to rotate, the rotating rod 13 drives the moving column 26 to rotate through the second T-shaped block 31, the moving column 26 drives the connecting column 29 to rotate through the cross plate 28, the connecting column 29 drives the L-shaped polishing plate 11 to rotate through the first T-shaped block 30, the L-shaped polishing plate 11 polishes the inner wall of the vessel 1, the discharge valve 12 is opened, the debris generated during polishing is discharged through the discharge valve 12 and then the discharge valve 12 is closed. When the L-shaped polishing plate 11 rotates, the moving rod 14 is moved upward in advance. Move the lever 37 to move the float 38 to the top of the L-shaped polishing plate 11. Then, pour the special oil into the vessel body 1 through the L-shaped tube 34. After the special oil is poured into the vessel body 1, remove the sealing plate 41 and attach it to the top of the adjusting ring 40. Connect the sealing plate 41 and the adjusting ring 40 with the fourth bolt 42 to seal the L-shaped tube 34. The special oil will cause the float 38 to move upward, which in turn causes the moving lever 37 to move upward. The moving lever 37 will then cause the limiting plate 39 to move upward, exposing the scale on the moving lever 37. The operator can then determine the volume of the special oil by observing the scale on the moving lever 37. At the same time, the special oil will cause the float plate 27 to move upward, which in turn causes the moving column 26 to move upward. The movable column 26 drives the cross plate 28, connecting column 29, and first T-shaped block 30 to move upward. The movable column 26 drives the second T-shaped block 31 to move upward. The second T-shaped block 31 moves from the first T-shaped groove to the T-shaped annular groove. At this time, the explosion-proof motor 18 is started. The explosion-proof motor 18 drives the transmission rod 19 to rotate. The transmission rod 19 drives the cross rod 20 to rotate. The cross rod 20 drives the rotating rod 13 to rotate. The rotating rod 13 drives the spiral stirring plate 14 and the fixed stirring plate 33 to rotate. The spiral stirring plate 14 and the fixed stirring plate 33 stir the special oil. The heat-conducting fins 15 heat the special oil. After processing is completed, the discharge valve 12 is opened to discharge the processed special oil. If it is necessary to clean the inside of the reactor body 1... During cleaning, first rotate the second bolt 22 to remove it from the first fixing ring 17 and the second fixing ring 21. Then move the explosion-proof motor 18 upward. The explosion-proof motor 18 drives the cross rod 20 upward through the transmission rod 19, thereby disassembling the explosion-proof motor 18. Next, rotate the first bolt 10 to remove it from the first flange 3 and the second flange 4. Then start the cylinder 5. The cylinder 5 drives the second flange 4 and the cover plate 8 upward through the connecting plate 6. The cover plate 8 drives the rotating rod 13 and the L-shaped polishing plate 11 upward. When the connecting plate 6 is away from the L-shaped plates 7 on both sides, rotate the cylinder 5 to the rear. The cylinder 5 drives the cross rod 9 to rotate, thereby removing the rotating rod 13 and the L-shaped polishing plate 11 from inside the vessel body 1.The L-shaped polishing plate 11 is moved, and the connecting column 29 and the cross plate 28 are moved by the first T-shaped block 30.
