Description

Technical Field

[0001] This invention relates to the field of buffer tank technology, and more specifically to an oil and gas mixed transport buffer tank. Background Technology

[0002] The main purpose of waste tire pyrolysis is to transform tires that are difficult to degrade naturally into high-value-added resources through thermochemical decomposition technology, thereby achieving the dual goals of environmental protection and economic benefits. After the waste tires are pyrolyzed, an oil-gas mixed transport buffer tank is needed to transport the oil and gas generated after the waste tires are pyrolyzed. The carbon black interception plate inside the oil-gas mixed transport buffer tank is used to intercept the carbon black, thereby separating the oil and gas from the carbon black powder, and then transporting the oil and gas and carbon black powder separately.

[0003] In most existing oil-gas mixed transport buffer tanks, multiple detachable carbon black interceptor plates are fixedly installed inside the tank. However, during the process of intercepting carbon black powder, some carbon black powder adheres to the surface of the interceptor plates, thus affecting the flow of oil and gas. Therefore, the carbon black interceptor plates need to be frequently disassembled and replaced to ensure the flow of oil and gas. Although this method can ensure the normal flow of oil and gas, the mixed transport buffer tank needs to be shut down when replacing the carbon black interceptor plates, which is not conducive to the continuous powder operation of oil, gas and carbon black, and reduces the operating efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an oil and gas mixed transport buffer tank, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An oil and gas mixed transport buffer tank includes a base, a processing box fixedly installed on the top of the base, a conveying pipe connected to the inside of the processing box fixedly installed on one side of the bottom of the processing box, a discharge pipe connected to the inside of the processing box fixedly installed on the other side, and an exhaust pipe connected to the inside of the processing box fixedly installed on the top of the processing box.

[0007] A vertically oriented rotating shaft is rotatably mounted at the top center of the processing box. A drive mechanism for rotating the shaft is installed at the top of the processing box. The bottom of the rotating shaft extends into the processing box and is fixedly mounted with a filter cover with an open bottom. The bottom of the filter cover is in contact with the bottom wall of the processing box and is fitted over the outside of the conveying pipe and the discharge pipe. Multiple filter holes are provided on the outer side wall and top of the filter cover. A filter cloth with an open bottom is inserted into the filter cover. The outer wall of the filter cloth is in contact with the inner wall of the filter cover. A shaft hole is provided at the top of the rotating shaft, and a through hole is provided at the top of the filter cloth, which is connected to the shaft hole. A positioning frame is installed at the bottom of the filter cover and inserted into the filter cloth. The top of the positioning frame extends through the shaft hole and is rotatably connected to the rotating shaft. The positioning frame is used to position the filter cloth.

[0008] The positioning frame includes an upper positioning ring, a connecting plate, a connecting shaft, a lower positioning ring, and a middle positioning plate. A horizontal connecting plate is integrally formed at the inner center of the upper positioning ring, and a vertical connecting shaft is integrally formed at the top center of the connecting plate. The connecting shaft can movably pass through a shaft hole and is rotatably connected to a rotating shaft. A middle positioning plate that fits against the bottom of the connecting plate is rotatably connected to the bottom of the upper positioning ring. The bottom of the filter cover has symmetrically opened insertion slots. Insertion plates are symmetrically fixed on the outer side wall of the lower positioning ring. The two insertion plates can be inserted into the inner side of the two insertion slots respectively, and the two insertion plates are fixed to the filter cover. The bottom of the middle positioning plate is inserted into the inner side of the lower positioning ring and is rotatably connected to the inner side wall of the lower positioning ring. When the two insertion plates are fixed to the filter cover, the upper positioning ring abuts against the inner top wall of the filter cloth, and the outer side walls of the upper positioning ring, lower positioning ring, and middle positioning plate all abut against the inner side wall of the filter cloth, so that the interior of the filter cloth is divided into two independent cavities by the middle positioning plate. One cavity is used for oil and gas output, and the other cavity is used for carbon black output.

[0009] The connecting shaft has a mounting hole in the middle that penetrates the connecting plate. A snap-fit ​​mechanism is installed on the top of the processing box, extending into the mounting hole and connecting to the central positioning plate. This snap-fit ​​mechanism has two states:

[0010] First state: The positioning plate is positioned between the central positioning plate and the processing box by a snap-fit ​​mechanism;

[0011] Second state: Positioning between the center positioning plate, connecting plate and rotating shaft is achieved through a snap-fit ​​mechanism.

[0012] Furthermore: the drive mechanism includes a motor 1 fixedly mounted on the top of the processing box, and the output shaft of the motor 1 is connected to the rotating shaft through a bevel gear assembly 1.

[0013] This invention provides an oil and gas mixed transport buffer tank. Compared with the prior art, it has the following advantages:

[0014] 1. Through the cooperation of the central positioning plate and the snap-fit ​​mechanism, the two chambers of this equipment can operate independently, respectively discharging oil and gas and carbon black powder. During this process, the central positioning plate cleans the inner wall of the filter cloth in real time, reducing the number of times the equipment needs to be stopped to clean the carbon black interception plate. This is conducive to continuous powder processing of oil and gas and carbon black, and improves the efficiency of operation.

[0015] 2. Through the design of the conveying components, when the carbon black powder flows downward through the discharge pipe during use, it falls into the conveying shell. The motor is turned on to drive the auger rod to rotate inside the conveying shell, thereby conveying the carbon black powder that falls into the conveying shell. This achieves the conveying effect of the carbon black powder discharged through the discharge pipe, which is beneficial for the feeding and conveying of carbon black powder.

[0016] 3. Through the design of the serpentine water guide pipe, when separating oil gas and carbon black powder, the water source in the water tank is drawn out by the external water tank pump and transported to the serpentine water guide pipe, and then discharged from the other end and flowed back to the external water tank. During this process, the temperature of the oil gas and carbon black mixture will be conducted to the middle positioning plate, thereby increasing the temperature of the middle positioning plate, which in turn is conducted to the serpentine water guide pipe, thus increasing the temperature of the water source flowing in the serpentine water guide pipe, achieving the purpose of waste heat recovery and utilization.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0030] To address the technical problems in the background section, the following oil and gas mixed transport buffer tank is provided:

[0031] Combination Figures 1-10 As shown, the present invention provides an oil and gas mixed transport buffer tank, including a base 1, a processing box 11 fixedly installed on the top of the base 1, a conveying pipe 12 connected to the inside of the processing box 11 fixedly installed on one side of the bottom of the processing box 11, a discharge pipe 13 connected to the inside of the processing box 11 fixedly installed on the other side, and an exhaust pipe 14 connected to the inside of the processing box 11 fixedly installed on the top of the processing box 11.

[0032] A vertically oriented rotating shaft 2 is rotatably mounted at the top center of the processing box 11. A drive mechanism 15 for rotating the rotating shaft 2 is mounted on the top of the processing box 11. The bottom of the rotating shaft 2 extends into the processing box 11 and is fixedly mounted with a filter cover 21 with an open bottom. The bottom of the filter cover 21 is flush with the inner bottom wall of the processing box 11, and the filter cover 21 is sleeved on the outside of the conveying pipe 12 and the discharge pipe 13. Multiple filter holes 211 are provided on the outer side wall and top of the filter cover 21. A filter with an open bottom is inserted into the filter cover 21. The filter cloth 212 is shaped like an orifice. The filter cloth 212 filters carbon black powder without affecting the normal flow of oil and gas. The outer wall of the filter cloth 212 is in contact with the inner wall of the filter cover 21. The top of the rotating shaft 2 is provided with a shaft hole 22 that penetrates the top of the filter cover 21. The top of the filter cloth 212 is provided with a through hole 213 that communicates with the shaft hole 22. The bottom of the filter cover 21 is equipped with a positioning frame 3 that is inserted into the filter cloth 212. The top of the positioning frame 3 extends through the shaft hole 22 and is rotatably connected to the rotating shaft 2. The positioning frame 3 is used to position the filter cloth 212.

[0033] The positioning frame 3 includes an upper positioning ring 31, a connecting plate 32, a connecting shaft 33, a lower positioning ring 34, and a middle positioning plate 35. A horizontally oriented connecting plate 32 is integrally formed at the inner center of the upper positioning ring 31. A vertically oriented connecting shaft 33 is integrally formed at the top center of the connecting plate 32. The connecting shaft 33 movably passes through a shaft hole 22 and is rotatably connected to a rotating shaft 2. A middle positioning plate 35, which fits against the bottom of the connecting plate 32, is rotatably connected to the bottom of the upper positioning ring 31. The bottom of the filter cover 21 has symmetrically symmetrically formed insertion slots 214. Insertion plates 341 are symmetrically fixed to the outer side wall of the lower positioning ring 34. The two insertion plates 341 can be inserted respectively. The two insertion slots 214 are connected to the inside of the filter cover 21 by screws. The bottom of the middle positioning plate 35 is inserted into the inside of the lower positioning ring 34 and is rotatably connected to the inner wall of the lower positioning ring 34. When the two insertion plates 341 are fixed to the filter cover 21 by screws, the upper positioning ring 31 abuts against the inner top wall of the filter cloth 212, and the outer walls of the upper positioning ring 31, the lower positioning ring 34 and the middle positioning plate 35 abut against the inner wall of the filter cloth 212. The middle positioning plate 35 divides the inside of the filter cloth 212 into two independent cavities. One cavity is used for oil and gas output, and the other cavity is used for carbon black output.

[0034] The connecting shaft 33 has a mounting hole 331 through the connecting plate 32 in the middle. The top of the processing box 11 is equipped with a snap-fit ​​mechanism 4 that extends into the mounting hole 331 and can be connected to the middle positioning plate 35. The snap-fit ​​mechanism 4 has two states:

[0035] First state: The positioning plate 35 is positioned between the processing box 11 by the snap-fit ​​mechanism 4;

[0036] Second state: Positioning between the center positioning plate 35, the connecting plate 32 and the rotating shaft 2 is achieved through the snap-fit ​​mechanism 4.

[0037] With the cooperation of the central positioning plate 35 and the snap-fit ​​mechanism 4, the two chambers of this equipment can operate independently, respectively discharging oil and gas and carbon black powder. During this process, the central positioning plate 35 cleans the inner wall of the filter cloth 212 in real time, reducing the number of times the equipment needs to be stopped to clean the carbon black interception plate. This is beneficial for continuous powder processing of oil and gas and carbon black, and improves operating efficiency.

[0038] Combination Figures 1-10 As shown, the drive mechanism 15 includes a motor 151 fixedly installed on the top of the processing box 11. The output shaft of the motor 151 is connected to the rotating shaft 2 through a bevel gear assembly 152. In use, the motor 151 is turned on and the output shaft of the motor 151 rotates, which drives the rotating shaft 2 to rotate through the bevel gear assembly 152, making it easy to control.

[0039] Combination Figures 1-10As shown, the snap-fit ​​mechanism 4 includes a fixed bracket 41 fixedly installed on the top of the processing box 11 and extending above the rotating shaft 2. A shaft 42 is vertically movably inserted through the mounting hole 331. A square block 43 is integrally formed at the bottom of the shaft 42. A square hole 351 is opened at the top of the middle positioning plate 35. A square hole 332 is opened at the bottom of the inner side wall of the mounting hole 331. The square block 43 can extend into the square hole 332 or the square hole 351. The outer side wall of the square block 43 fits the cross section between the square hole 332 and the inner side wall of the square hole 351. A vertical drive rod 44 is fixedly installed on the top of the connecting shaft 33 and on one side of the mounting hole 331. A horizontal plate 45 fixedly installed on the top of the drive rod 44 and connected to the top of the shaft 42. A vertical rotating shaft 46 is fixedly installed on the top of the horizontal plate 45. The rotating shaft 46 moves vertically to the fixed bracket 41. A locking hole 411 is symmetrically provided on both sides of the rotating shaft 46 on the fixed frame 41. A locking plate 47 is fixedly installed on the top of the rotating shaft 46. A locking post 48, which can be inserted into the two locking holes 411 respectively, is fixedly installed on the bottom of the locking plate 47. A positioning frame 49 is fixedly installed on the inner side wall of the shaft hole 22. The horizontal plate 45 can be inserted into the positioning frame 49 and locked with it. Specifically, the square block 43 is located inside the square hole 351. When the horizontal plate 45 is engaged with the middle positioning plate 35, the horizontal plate 45 is located below the positioning frame 49, and the two locking pins 48 are respectively inserted into the two locking holes 411 and engaged with the fixing frame 41. When the horizontal plate 45 is inserted into the positioning frame 49 and engaged with it, the block 43 is simultaneously located inside the second square hole 332 and the first square hole 351. The block 43 is engaged with both the middle positioning plate 35 and the connecting shaft 33, and the two locking pins 48 are both located above the fixing frame 41.

[0040] Combination Figures 1-10As shown, the processing box 11 includes a box body 111 fixedly installed on the top of the base 1. The top of the box body 111 is open, and an annular groove 112 is formed on the top of the box body 111 and outside its open end. An annular insert plate 113 is inserted into the annular groove 112 on the box body 111. The annular insert plate 113 and the annular groove 112 are in contact at their cross-sections. In this embodiment, a rubber pad is fixedly installed on the inner bottom wall of the annular groove 112. When the annular insert plate 113 is inserted into the annular groove 112, the annular insert plate 113 abuts against the rubber pad. The top of the annular insert plate 113 is integrally formed with a box cover 114 for sealing the open end of the box body 111. Both sides of the box body 111 are fixed. A second drive rod 115 connected to the cover 114 is installed. The motor 151, exhaust pipe 14 and fixing bracket 41 are all fixedly installed on the cover 114. The rotating shaft 2 is rotatably installed on the cover 114. The conveying pipe 12 and the discharge pipe 13 are both fixedly installed at the bottom of the box body 111. When it is necessary to replace the filter cloth 212, the cover 114 can be lifted upward by the two drive rods 115, so that the filter cover 21 is moved to the top of the box body 111. At this time, the screws used to fix the plug plate 341 and the filter cover 21 can be removed, so that the positioning bracket 3 can be pulled out from the filter cover 21 as a whole, thereby disassembling and replacing the filter cloth 212, which is convenient for replacing the filter cloth 212.

[0041] Combination Figures 1-10 As shown, a conveying assembly 16 connected to the bottom of the discharge pipe 13 is installed on the base 1. The conveying assembly 16 includes a conveying shell 161 fixedly installed on the base 1 and located below the discharge pipe 13. The bottom of the discharge pipe 13 passes through the top of the conveying shell 161 and is connected to its interior. An auger rod 162 is rotatably installed inside the conveying shell 161. The outer wall of the auger rod 162 is in contact with the inner wall of the conveying shell 161. A motor 163 for driving the auger rod 162 to rotate is fixedly installed on the conveying shell 161. Through the design of the conveying assembly 16, when the carbon black powder flows downward through the discharge pipe 13 and is discharged, it falls into the conveying shell 161. The motor 163 is turned on to drive the auger rod 162 to rotate inside the conveying shell 161, thereby conveying the carbon black powder that falls into the conveying shell 161. This achieves the effect of conveying the carbon black powder discharged through the discharge pipe 13, which is beneficial for the feeding and conveying of carbon black powder.

[0042] Combination Figures 1-10 As shown, a sealing mechanism 5 that can be fitted onto the outside of the filter cover 21 is installed at the bottom of the box cover 114. A solenoid valve 141 is fixedly installed on the exhaust pipe 14. An air inlet pipe 142 that communicates with the inside of the exhaust pipe 14 is fixedly installed on the side of the exhaust pipe 14 near the solenoid valve 141. A solenoid valve 143 is opened on the air inlet pipe 142.

[0043] The sealing mechanism 5 includes a vertical rod 51, an annular plate 52, an annular rubber sleeve 53, and a driving mechanism 54. The vertical rod 51 is vertically movably inserted through the cover 114 outside the filter cover 21. The bottom of the vertical rod 51 is fixedly installed with an annular plate 52 that is sleeved on the outside of the filter cover 21. The inner top wall of the cover 114, outside the filter cover 21 and the exhaust pipe 14, has a receiving groove 1141. The annular plate 52 can seal the bottom opening of the receiving groove 1141. The inner top wall of the receiving groove 1141 is fixedly installed with an annular rubber sleeve 53 that can be sleeved on the outside of the filter cover 21. The bottom of the annular rubber sleeve 53 is fixedly connected to the top of the annular plate 52. The cover 114 is equipped with a driving mechanism 54 connected to the annular plate 52, which is used to make the annular plate 52 slide along the vertical rod 51 or stop sliding.

[0044] Combination Figures 1-10 As shown, the driving mechanism 54 includes a threaded post 541 that is vertical and movably passes through the box cover 114. The bottom of the threaded post 541 is rotatably connected to the annular plate 52. The threaded post 541 is externally threaded and fitted with a threaded sleeve 542 that is rotatably connected to the top of the box cover 114. A second motor 543 is fixedly installed on the top of the box cover 114. The output shaft of the second motor 543 is connected to the threaded sleeve 542 through a bevel gear assembly 544. In use, the second motor 543 is turned on, and the output shaft of the second motor 543 rotates, which drives the threaded sleeve 542 to rotate on the box cover 114 through the bevel gear assembly 544. This causes the threaded post 541 to move spirally inside the threaded sleeve 542. The threaded post 541 rotates with the annular plate 52, which in turn causes the annular plate 52 to slide along the upright 51, making it easy to control.

[0045] Combination Figures 1-10 As shown, vertical grooves 352 are provided on both sides of the central positioning plate 35. A slider 353 is vertically slidably installed on the central positioning plate 35 and located in the grooves 352. An electromagnetic slider 354 connected to the slider 353 is fixedly installed in the grooves 352. A scraping mechanism 6 for scraping and cleaning the side wall of the central positioning plate 35 is installed on the slider 353.

[0046] Combination Figures 1-10As shown, the scraping mechanism 6 includes a connecting block 61 fixedly installed at the end of the slider 353 and in contact with the middle positioning plate 35. Both sides of the connecting block 61 are hinged with scraper blades 62 that can be in contact with the side wall of the middle positioning plate 35. Both ends of the scraper blades 62 are arc surfaces, and the center of the arc surface is located in the axial direction of the rotating shaft 2. A fixing plate 63 is fixedly installed on the side of the connecting block 61 away from the middle positioning plate 35. A sliding block 64 is slidably installed on the bottom of the fixing plate 63 along the direction of the connecting block 61. Both sides of the sliding block 64 are hinged with hinge rods 65. The other ends of the two hinge rods 65 are respectively hinged to the two scraper blades 62. A drive rod 66 for driving the sliding block 64 to slide is fixedly installed on the bottom of the fixing plate 63.

[0047] Combination Figures 1-10 As shown, a mounting cavity 355 is provided in the middle of the positioning plate 35 and below the square hole 351. A serpentine water guide pipe 7 is fixedly installed in the mounting cavity 355. Specifically, the two ends of the serpentine water guide pipe 7 are connected to the inlet of the external water tank and the outlet of the external water tank pump. The two ends of the serpentine water guide pipe 7 pass through the top of the positioning plate 35 and are located on both sides of the square hole 351. The two ends of the serpentine water guide pipe 7 also pass through the top of the connecting shaft 33. Through the design of the serpentine water guide pipe 7, when separating oil gas and carbon black powder, the water source in the water tank is drawn out by the external water tank pump and transported to the serpentine water guide pipe 7, and then discharged from the other end and flowed back to the external water tank. During this process, the temperature of the oil gas and carbon black mixture will be conducted to the positioning plate 35, thereby increasing the temperature of the positioning plate 35. This temperature is then conducted to the serpentine water guide pipe 7, increasing the temperature of the water flowing in the serpentine water guide pipe 7, thus achieving the purpose of waste heat recovery and utilization.

[0048] Working principle and usage process of this invention:

[0049] In the first step, during the separation of oil gas and carbon black powder, the mixture of oil gas and carbon black powder is transported through the conveying pipe 12 to the cavity connected to the conveying pipe 12. During this process, the control drive rod 44 moves the horizontal plate 45 downward, causing the two locking pins 48 to be inserted into the two locking holes 411 and locked with the fixing frame 41. The block 43 is located inside the square hole 351 and locked with the middle positioning plate 35. The control motor 151 is turned on, driving the rotating shaft 2 to rotate. The filter cover 21 rotates around the rotating shaft 2, and the middle positioning plate 35 rotates with both the upper positioning ring 31 and the lower positioning ring 34. The control solenoid valve 14 is activated. 1. With the solenoid valve 143 closed, the oil-gas-carbon black mixture enters the cavity. The filter cloth 212 filters the carbon black powder, leaving it inside. The oil-gas passes through the filter cloth 212 and filter holes 211, then exits through the exhaust pipe 14, achieving the desired oil-gas-carbon black powder effect. During this process, as the oil-gas passes through the filter holes 211, the filter cover 21 rotates around the shaft 2, dispersing the oil-gas exiting through the filter holes 211 and buffering the exiting oil-gas. Furthermore, the rotation of the filter cover 21 around the shaft 2 causes the filter cloth 212 to rotate synchronously, thus allowing the positioning plate 35 to achieve the desired effect. The inner wall of the filter cloth 212 is scraped and cleaned, causing the carbon black powder to fall onto the bottom wall of the cavity under its own gravity, preventing the carbon black powder from adhering to the inner wall of the filter cloth 212 and affecting the discharge of oil and gas. In addition, when separating oil and gas and carbon black powder, the drive rod 66 inside the cavity connected to the conveying pipe 12 is controlled to make the sliding block 64 slide back and forth on the fixed plate 63. The ends of the two hinge rods 65 rotate around their hinge points on both sides of the sliding block 64, and the other ends of the two hinge rods 65 rotate between the two scrapers 62. The two scrapers 62 move back and forth on both sides of the connecting block 61. The rotating mechanism allows the flowing gas inside the cavity to circulate through the two scrapers 62, further buffering the oil and gas discharge. Furthermore, the design of the serpentine water pipe 7 allows for the separation of oil and gas from carbon black powder. An external water tank pump draws water from the tank and delivers it to the serpentine water pipe 7, from which it is discharged back to the external tank. During this process, the temperature of the oil and gas mixture is conducted to the central positioning plate 35, causing its temperature to rise. This, in turn, raises the temperature of the water flowing within the serpentine water pipe 7, achieving waste heat recovery.

[0050] In the second step, after the oil and gas and carbon black powder have been separated for a period of time, when the carbon black powder collected in the cavity connected to the conveying pipe 12 is discharged, the drive rod 44 is controlled to move the horizontal plate 45 upward, so that the horizontal plate 45 is inserted into the positioning frame 49 and engaged with it. At this time, the block 43 is simultaneously located inside the square hole 332 and the square hole 351. The block 43 is engaged with the middle positioning plate 35 and the connecting shaft 33. The two engaging posts 48 are located above the fixing frame 41. The motor 151 causes the rotating shaft 2 to rotate 180 degrees, and the filter cover 21... Both the positioning plate 35 and the rotating shaft 2 rotate, causing the two cavities inside the filter cover 21 to interchange. At this time, the cavity connected to the conveying pipe 12 separates the oil-gas-carbon black mixture, while the cavity connected to the conveying pipe 12 connects to the discharge pipe 13. The carbon black powder in the cavity can then fall into the conveying shell 161 through the discharge pipe 13. The control motor 163 is turned on, driving the auger rod 162 to rotate inside the conveying shell 161, thus conveying the carbon black powder falling into the conveying shell 161 and realizing the processing of the carbon black powder discharged through the discharge pipe 13. During conveying, the electromagnetic slider 354 moves the slider 353 to the top of the chute 352. The drive rod 66 inside the cavity connected to the discharge pipe 13 causes the sliding block 64 to slide on the fixed plate 63. The ends of the two hinge rods 65 rotate around their hinge points on both sides of the sliding block 64, and the other ends of the two hinge rods 65 rotate between the two scrapers 62, causing both scrapers 62 to contact the central positioning plate 35. At this time, the electromagnetic slider 354 causes the slider 353 to slide downwards, thus allowing the two... The scraper 62 scrapes the carbon black powder adhering to the side wall of the middle positioning plate 35, thereby cleaning the carbon black powder adhering to the side wall of the middle positioning plate 35 and facilitating the discharge of carbon black powder. Thus, through the cooperation of the middle positioning plate 35 and the snap-fit ​​mechanism 4, the two chambers of this equipment can operate independently, discharging oil and gas and carbon black powder respectively. During this process, the middle positioning plate 35 cleans the inner wall of the filter cloth 212 in real time, reducing the number of times the equipment needs to be stopped to clean the carbon black interception plate, which is conducive to continuous powder operation of oil and gas and carbon black, and improves the operation efficiency.

[0051] Thirdly, after long-term use, the control motor 543 is turned on, driving the threaded sleeve 542 to rotate on the cover 114 via the bevel gear assembly 544. The threaded column 541 rotates with the annular plate 52, causing the annular plate 52 to slide downwards along the upright 51 and fit against the inner bottom wall of the housing 111. The annular rubber sleeve 53 deforms and fits over the filter cover 21, reducing the overall space outside the filter cover 21. At this time, an external air pump connected to the air inlet pipe 142 is used to close the solenoid valve 141 and open the solenoid valve 143, controlling the external air pump to deliver gas into the air inlet pipe 142. This allows the gas to flow into the annular rubber sleeve 53, and then back-blown through multiple filter holes 211 to clean the filter cloth 212. When the filter cloth 212 needs to be replaced, the cover is turned on by two drive rods 115. 114 is pushed upwards, causing the filter cover 21 to move above the housing 111. The screws used to fix the plug-in plate 341 and the filter cover 21 are then removed, allowing the positioning frame 3 to be pulled out from the filter cover 21. The filter cloth 212 can then be removed from the positioning frame 3. After removal, the perforation 213 on the new filter cloth 212 is fitted onto the outside of the connecting shaft 33, so that the filter cloth 212 is fitted onto the outside of the positioning frame 3. The connecting shaft 33 passes through the shaft hole 22, allowing the two plug-in plates 341 to be inserted into the two plug-in slots 214 respectively. The two plug-in plates 341 are then fixed to the filter cover 21 with screws, thus completing the replacement of the filter cloth 212. The two drive rods 115 are used to move the housing cover 114 downwards, causing the annular plug-in plate 113 to be inserted into the annular groove 112, so that the housing cover 114 fits against the housing 111, allowing the equipment to be used subsequently.
