[0002] Pyrolysis refers to the reaction of destroying the high molecular bonding state of organic substances by heating and decomposing them into low molecular substances. The products of the reaction are gas, oil and coke. J. Jones of Stanford Research Institute (SRI) put forward a strict definition. He defined pyrolysis as "the process of thermochemically decomposing carbon-containing organic substances by indirect heating to produce fuels (gas, liquid and carbon black) without introducing oxygen, steam or high-temperature carbon monoxide into the reactor". At present, pyrolysis technology has been widely applied to various waste treatment fields, such as pyrolysis treatment of waste rubber and plastics (waste tires, plastics, etc.), such as municipal waste treatment (including household waste and water plant sediments, etc.), such as medical waste treatment (non-recyclable medical waste, harmless treatment of medical appliances, etc.).

[0012] The present invention also provides a method for using the above-mentioned solid waste pyrolysis oil refining treatment equipment, and the method includes the following steps.

[0013] Step 1: First, put the waste into the tank body, and then drive the rotating gear to rotate by starting the driving device, so that the toothed disc drives the tank body to rotate, and heat and decompose the waste inside the tank body through the heating device.

[0014] Step 2: Subsequently, when the waste inside the tank body is heated and decomposed, the gas after heating and decomposition flows into the inside of the exhaust pipe through the confluence pipe, so that one side of the baffle deflects towards the inside of the exhaust pipe, and the tension spring is compressed.

[0019] 2. By the combined use of a connecting seat, an electric push rod, a connecting plate, a repair block, a storage tank, repair liquid and a nozzle, the electric push rod is used to push the connecting plate up and down, so that the connecting plate drives the repair block to move up and down.

DETAILED DESCRIPTION OF THE INVENTION

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] The present invention provides a multifunctional electrical equipment detection device, as Figures 1-4 shown, including a tank body 1. A tank door is provided on one side of the tank body 1. A gear disk 2 is fixedly connected to the other end of the tank body 1. A heating device is arranged inside the tank body 1. A fixed base 3 is provided at the bottom of the tank body 1. Two ends of the top of the fixed base 3 are fixedly connected with a supporting rotating frame 4. A rotating roller 5 is fixedly connected to the top of the supporting rotating frame 4. The outer surface of the rotating roller 5 is tangent to the outer surface of the tank body 1. A manifold 6 is fixedly connected to the top of the tank body 1. An exhaust pipe 7 is fixedly connected to the top of the manifold 6. The top end of the exhaust pipe 7 is fixedly connected with a flue gas purification device. A rotating gear 8 is engaged with one side of the gear disk 2. A driving device 9 is fixedly connected to one side of the rotating gear 8. A connecting pipe is fixedly connected to the middle of one side of the tank body 1. One end of the connecting pipe is fixedly connected with a cooling device 10. A rotating shaft 11 is arranged inside the exhaust pipe 7. A first gear 12 is fixedly connected to the top end of the rotating shaft 11. A second gear 13 is engaged with one side of the top of the first gear 12. A rotating rod 14 is fixedly connected to the middle of the second gear 13. Fan blades 15 are fixedly connected to both ends of the rotating rod 14. The bottom of the rotating shaft 11 is rotatably connected with a baffle 16. A tension spring 17 is fixedly connected to the top of the baffle 16. A fixing ring 18 is fixedly connected to the top of the tension spring 17. A first fixing rod 19 is fixedly connected to the inner wall of the fixing ring 18. One end of the first fixing rod 19 is fixedly connected with a connecting ring 20. The inner wall of the connecting ring 20 is fixedly connected with the rotating shaft 11. A compression spring 21 is fixedly connected to the outer surface of the fixing ring 18. One end of the compression spring 21 is fixedly connected with a cleaning ring 22.

[0029] First, put the waste into the interior of the tank body 1, and then start the driving device 9 to drive the rotating gear 8 to rotate, so that the toothed disc 2 drives the tank body 1 to rotate. Heat and decompose the waste inside the tank body 1 through the heating device. Subsequently, when the waste inside the tank body 1 is heated and decomposed, the gas after heating and decomposition squeezes the baffle 16 upward through the confluence pipe 6, causing one side of the baffle 16 to deflect into the interior of the exhaust pipe 7, and the tension spring 17 is compressed. When the gas passes through the interior of the exhaust pipe 7, the fan blade 15 rotates, rotates the rotating rod 14, thereby driving the first gear 12 and the second gear 13 to rotate, rotates the rotating shaft 11, and the rotating shaft 11 drives the connecting ring 20 to rotate, so that the first fixing rod 19 connected to the connecting ring 20 drives the fixing ring 18 to rotate, stretches the compression spring 21, and makes the cleaning ring 22 rotate while fitting with the inner wall of the exhaust pipe 7, cleaning the inner wall of the exhaust pipe 7, preventing impurities from adhering to the inner wall of the exhaust pipe 7 when the gas enters the exhaust pipe 7, which is not conducive to the effect of the exhaust pipe 7 and is likely to cause blockage of the exhaust pipe 7 after a long time, and is not conducive to use.

[0030] As Figures 4-5 shown, the fan blade 15 is located at the top end inside the exhaust pipe 7. There are two groups of fan blades 15. One side of the fan blade 15 close to the inner wall of the exhaust pipe 7 is fixedly connected with a cleaning block 23, and the cleaning block 23 fits with the inner wall of the exhaust pipe 7.

[0031] When the gas enters the exhaust pipe 7, the gas makes the fan blade 15 rotate, and the fan blade 15 drives the cleaning block 23 to rotate, cleaning the inner wall at the top end of the exhaust pipe 7, making the cleaning of the exhaust pipe 7 more comprehensive.

[0032] As Figures 3-4 shown, the inner wall of the exhaust pipe 7 is fixedly connected with a second fixing rod. The middle part of the second fixing rod is rotatably connected with the rotating shaft 11. Both ends of the rotating rod 14 are rotatably connected with the inner wall of the exhaust pipe 7. The second fixing rod is located at the bottom of the rotating rod 14. The fixing ring and the cleaning ring 22 are linearly arranged along the rotating shaft 11. The fixing ring 18 is located between the first gear 12 and the baffle 16. The first fixing rod 19 is circularly arranged with the center of the connecting ring 20 as the center.

[0033] The rotating shaft 11 is fixed by the second fixing rod, so that the rotating shaft 11 remains stable when rotating. Since the fixing ring 18 and the cleaning ring 22 are linearly arranged along the rotating shaft 11, it is convenient to fixedly connect the connecting ring 20 and the fixing ring 18 through the second fixing rod, and it is convenient for the fixing ring 18 and the cleaning ring 22 at the bottom end to rotate when the rotating shaft 11 rotates, so as to clean the exhaust pipe 7 from top to bottom, thus facilitating the use of the exhaust pipe 7.

[0034] As Figures 3-4As shown, the compression spring 21 is located between the fixed ring 18 and the cleaning ring 22. There are two compression springs 21. A repair structure 24 is provided between the fixed rings 18, and the number of the repair structure 24 is the same as that of the cleaning ring 22.

[0035] When the fixed ring 18 rotates, the compression spring 21 connected to the outer surface of the fixed ring 18 is stretched, so that the cleaning ring 22 moves in the reverse direction towards the exhaust pipe 7, making the cleaning ring 22 fit against the inner wall of the exhaust pipe 7, facilitating the cleaning of the inside of the exhaust pipe 7 by the cleaning ring 22. The repair structure 24 facilitates the repair of the inner wall of the exhaust pipe 7 and the service life of the exhaust pipe 7.

[0036] As Figures 4-5 shown, the repair structure includes a connection seat 241. The bottom of the connection seat 241 is fixedly connected to the tension spring 17. The middle of the connection seat 241 is fixedly connected to the rotating shaft 11. An electric push rod 242 is arranged inside the connection seat 241. One side of the electric push rod 242 is fixedly connected to a connection plate 243. One side of the connection plate 243 is fixedly connected to a repair block 244. One side of the repair block 244 is fixedly connected to a nozzle 245. Grooves are opened at both ends of the top of the connection seat 241. A sliding groove is opened on one side of the groove. The inner wall of the top of the groove is fixedly connected to the electric push rod 242. The connection plate 243 passes through the groove and extends to the outside of the connection seat 241. The connection plate 243 is slidably connected to the sliding groove. The repair blocks 244 are located on both sides of the connection seat 241. A storage tank 246 is arranged inside the repair block 244. A repair liquid is arranged inside the storage tank 246. A spray pipe is fixedly connected to one side of the storage tank 246. The spray pipe passes through the repair block 244 and is fixedly connected to the nozzle 245.

[0037] The connection seat 241 is fixedly connected by the rotating shaft 11. By starting the electric push rod 242 to drive the connection plate 243 to move in the sliding groove, the connection plate 243 drives the repair block 244 to move. When the repair block 244 moves, the internal storage tank 246 sprays the repair liquid through the spray pipe and the nozzle 245, making the spray pipe move up and down, so as to facilitate spraying the repair liquid on the inner wall of the exhaust pipe 7, which is beneficial to comprehensively repair the inner wall of the exhaust pipe 7, facilitate the use of the exhaust pipe 7, and improve the service life of the exhaust pipe 7.

[0038] As Figure 6 shown, the present invention also provides a method for using the above-mentioned solid waste pyrolysis oil refining treatment equipment. The method includes the following steps:

[0039] Step 1: First, put the waste into the tank body 1, and then start the driving device 9 to drive the rotating gear 8 to rotate, so that the gear disk 2 drives the tank body 1 to rotate, and heat the waste inside the tank body 1 through the heating device for decomposition;

[0040] Step 2: Subsequently, after the waste inside the tank body 1 is heated and decomposed, the gas after heating and decomposition flows into the interior of the exhaust pipe 7 through the manifold pipe 6, causing one side of the baffle plate 16 to deflect towards the interior of the exhaust pipe 7, and the tension spring 17 is compressed. When the gas passes through the interior of the exhaust pipe 7, the fan blade 15 rotates, rotating the rotating rod 14, thereby driving the first gear 12 and the second gear 13 to rotate, rotating the rotating shaft 11. The rotating shaft 11 drives the connecting ring 20 to rotate, causing the first fixing rod 19 connected to the connecting ring 20 to drive the fixing ring 18 to rotate, stretching the compression spring 21, so that the cleaning ring 22 rotates while being in contact with the inner wall of the exhaust pipe 7 to clean the inner wall of the exhaust pipe 7;

[0041] Step 3: Subsequently, the gas enters the flue gas purification device through the exhaust pipe 7 for filtration, and the discharged gas is processed. After the gas is exhausted, there is no gas flow inside the exhaust pipe 7. Under the action of the tension spring 17, the baffle plate 16 deflects to one side, rotating the baffle plate 16 back to its original position to block the bottom of the exhaust pipe 7;

[0042] Step 4: Finally, start the electric push rod 242 to drive the connecting plate 243 to move up and down, so that the connecting plate 243 drives the repair block 244 to move up and down. Then, the repair liquid inside the storage tank 246 is sprayed out from the nozzle 245 through the spray pipe. When the repair block 244 moves up and down, the nozzle 245 evenly sprays the repair liquid on the inner wall of the exhaust pipe 7 to repair the inner wall of the exhaust pipe 7.

[0043] Working principle: When in use, put the waste into the tank body 1, and then start the driving device 9 to drive the rotating gear 8 to rotate, so that the gear disc 2 drives the tank body 1 to rotate. The waste inside the tank body 1 is heated and decomposed by the heating device. Subsequently, after the waste inside the tank body 1 is heated and decomposed, when the gas after heating and decomposition enters the exhaust pipe 7 through the manifold pipe 6, it squeezes the baffle plate 16 upwards, causing one side of the baffle plate 16 to deflect towards the interior of the exhaust pipe 7, and the tension spring 17 is compressed. When the gas passes through the interior of the exhaust pipe 7, the fan blade 15 rotates, rotating the rotating rod 14, thereby driving the first gear 12 and the second gear 13 to rotate, rotating the rotating shaft 11. The rotating shaft 11 drives the connecting ring 20 to rotate, causing the first fixing rod 19 connected to the connecting ring 20 to drive the fixing ring 18 to rotate, stretching the compression spring 21, so that the cleaning ring 22 rotates while being in contact with the inner wall of the exhaust pipe 7 to clean the inner wall of the exhaust pipe 7, preventing impurities from adhering to the inner wall of the exhaust pipe 7 when the gas enters the exhaust pipe 7, which is not conducive to the effect of the exhaust pipe 7 and is likely to cause blockage of the exhaust pipe 7 after a long time, thus being not conducive to use.

[0044] After cleaning is completed, start the electric push rod 242 to drive the connecting plate 243 to move in the chute, so that the connecting plate 243 drives the repair block 244 to move up and down. Then, spray the repair liquid inside the storage tank 246 from the nozzle 245 through the spray pipe. When the repair block 244 moves up and down, the nozzle 245 evenly sprays the repair liquid on the inner wall of the exhaust pipe 7 to repair the inner wall of the exhaust pipe 7.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.

When the gas passes through the inside of the exhaust pipe (7), the fan blade (15) rotates, and the rotating rod (14) rotates, thereby driving the first gear (12) and the second gear (13) to rotate, and the rotating shaft (11) drives the connecting ring (20) to rotate, so that the first fixed rod (19) connected to the connecting ring (20) drives the fixed ring (18) to rotate, and the compression spring (21) is stretched, so that the cleaning ring (22) rotates and fits with the inner wall of the exhaust pipe (7), thereby cleaning the inner wall of the exhaust pipe (7); Step 3: The gas then passes through the exhaust pipe (7) and enters the flue gas purification device for filtration, and the exhausted gas is processed. After the gas is exhausted, there is no gas flow in the exhaust pipe (7). Under the action of the tension spring (17), the baffle (16) is deflected to one side, and the baffle (16) is rotated to its original position to cover the bottom of the exhaust pipe (7); Step 4: Finally, the electric push rod (242) is started to drive the connecting plate (243) to move up and down, so that the connecting plate (243) drives the repair block (244) to move up and down, and then the repair liquid inside the storage box (246) is sprayed out from the nozzle (245) through the nozzle. When the repair block (244) moves up and down, the nozzle (245) evenly sprays the repair liquid on the inner wall of the exhaust pipe (7) to repair the inner wall of the exhaust pipe (7).
