Technical Field
[0001] This invention relates to the field of flue cleaning technology, and more specifically, to a device and method for unblocking and cleaning compressor flues to prevent clogging. Background Technology
[0002] The continuous hot pressing process of medium-density fiberboard and high-density fiberboard continuously generates complex process exhaust gases. Long-term operation of the exhaust pipes can easily lead to the adhesion and deposition of pollutants. Existing cleaning and maintenance methods are difficult to adapt to the requirements of continuous production of engineered wood products. Existing self-cleaning flue solutions also do not fully match the unique physicochemical deposition characteristics of hot pressing exhaust gases. Against this background, we developed a self-cleaning press flue unblocking device and method to build a self-maintaining exhaust structure, which can solve the problem of flue accumulation and blockage, ensure the continuous and stable operation of the production line, and meet environmental protection and production control requirements.
[0003] A search revealed a flue debris cleaner proposed in Chinese Patent (Announcement No.: CN117213266A), comprising: a mounting cylinder with multiple elastic mechanisms arranged circumferentially on its outer wall, the elastic mechanisms being able to spring outwards or retract inwards relative to the outer wall of the mounting cylinder; a driving wheel rotatably connected to the elastic mechanisms, the driving wheel contacting the inner wall of the flue; an energy power unit fixed inside the mounting cylinder, the output end of the energy power unit extending outwards from one end of the mounting cylinder; a storage and transport cylinder with a flexible telescopic joint connected to one end of the storage and transport cylinder, the flexible telescopic joint being detachably connected to one end of the mounting cylinder; multiple guide wheels rotatably connected to the outer wall of the storage and transport cylinder; and a receiving head rotatably connected inside the storage and transport cylinder and drivingly connected to the output end. This invention has a simple structure and is suitable for cleaning and unclogging straight and curved flues.
[0004] In actual use, the above solution requires early shutdown, air cut-off, cooling and pressure relief, which is a high-risk operation in a confined space. The supporting auxiliary systems such as protection and gas detection are complicated. At the same time, the motor and walking mechanism of the cleaning equipment are easily stuck by oil and grease and fail, resulting in a short service life. This cleaning method can only be used as an emergency measure and cannot form a closed loop with the compressor's operating rhythm and differential pressure signal, making it difficult to meet the continuous online self-maintenance requirements of the flue debris cleaner.
[0005] Therefore, we have made improvements and proposed a self-cleaning compressor flue unblocking device and method to solve the problems mentioned above. Summary of the Invention
[0006] The purpose of this invention is to provide a device and method for unclogging and cleaning compressor flues to solve the problems mentioned in the background art.
[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution:
[0008] The anti-clogging self-cleaning compressor flue unblocking device includes a connecting pipe, a flue pipe installed at the top of the connecting pipe, a slag discharge pipe installed at the bottom of the connecting pipe, a flue pipe installed on one side of the connecting pipe, and an isolation net installed at the connection position between the connecting pipe and the flue pipe. It also includes:
[0009] A cleaning component, located inside the connecting pipe, is used to clean the inner walls of the connecting pipe and the exhaust pipe;
[0010] A guide component, located inside the exhaust pipe, guides the cleaning end of the cleaning component, allowing the cleaning end to rotate and assisting in cleaning the inner wall of the exhaust pipe.
[0011] The water spray component, located on the outside of the connecting pipe, works in conjunction with the guide component to help remove the cleaned oil and impurities.
[0012] The drive component, located on one side of the bottom of the connecting pipe, provides power support for the operation of the bottom structure.
[0013] The crushing component is located inside the connecting pipe and is driven by the drive component to crush and discharge oil and impurities.
[0014] The vibration component, located on the outside of the connecting pipe, assists in cleaning and discharging impurities through the vibration it generates.
[0015] As a preferred technical solution of this application, the cleaning component includes a hydraulic rod installed at the bottom of the slag discharge pipe, a piston rod sliding inside the hydraulic rod, a cleaning head installed at the top of the piston rod, and a dredging groove opened on the outside of the cleaning head.
[0016] The cleaning head is slidably connected to the exhaust pipe and is used to clean the inner wall of the exhaust pipe.
[0017] As a preferred technical solution of this application, the guide assembly includes a fixing ring fixedly installed on the inner side of the top of the exhaust pipe and a spiral tube fixedly installed at the bottom of the fixing ring;
[0018] The spiral tube is fixed inside the exhaust pipe by a fixing ring, and the spiral tube itself does not move or rotate;
[0019] The spiral tube is slidably connected to the cleaning head.
[0020] As a preferred technical solution of this application, the water spray assembly includes multiple nozzles opened on the spiral tube, a fixed frame installed on the outer side of the middle end of the exhaust pipe, a high-pressure pump installed on the fixed frame, and a water inlet pipe installed at the output end of the high-pressure pump.
[0021] The water inlet pipe is connected to the spiral pipe through the fixing ring.
[0022] As a preferred technical solution of this application, the plurality of nozzles are arranged in a spiral array along the inner wall of the spiral tube. When the high-pressure water flows out through the fixed spiral tube, it forms a rotating water curtain, which, together with the lifting and lowering movement of the cleaning head, washes away the oil stains adhering to the inner wall of the exhaust pipe.
[0023] As a preferred technical solution of this application, the drive assembly includes a fixed sleeve installed on the outside of the connecting pipe, a drive motor installed on the outside of the fixed sleeve, a transmission rod installed on the output end of the drive motor, a first bevel gear installed on the end of the transmission rod, and a second bevel gear disposed at the bottom of the first bevel gear.
[0024] As a preferred technical solution of this application, the crushing assembly includes a support frame installed on the inner side of the bottom of the connecting pipe, a protective cover installed on the top of the support frame, a transmission sleeve rotating on the top of the support frame, a rotating head installed on the top of the transmission sleeve, and a crushing blade installed on the outside of the rotating head.
[0025] The piston rod passes through the support frame, the transmission sleeve, and the rotating head, and is slidably connected to the support frame, the transmission sleeve, and the rotating head;
[0026] The top of the rotating head is designed with a conical structure, and the crushing blades are arranged in an inclined manner around the outside of the rotating head. After the falling clumps of impurities come into contact with the conical surface, they are dispersed in all directions and crushed by the rotating crushing blades.
[0027] As a preferred technical solution of this application, the vibration assembly includes a limiting plate installed on the top of the fixed sleeve, a driving gear installed on the outside of the transmission rod, a transmission gear set disposed on the inside of the limiting plate, a hexagonal prism rotating on the inside of the top of the limiting plate, a driven gear ring installed at the middle end of the hexagonal prism, and a stress frame installed on the outside of the connecting pipe.
[0028] The driving gear meshes with the bottom of the transmission gear set, and the top of the transmission gear set meshes with the driven gear ring.
[0029] The hexagonal prism is slidably connected to the stress frame.
[0030] As a preferred technical solution of this application, a buffer pad is installed on the side of the stress frame near the connecting pipe. The buffer pad abuts against the outer wall of the connecting pipe. When the hexagonal prism slides up and down, the stress frame drives the connecting pipe to generate high-frequency micro-amplitude vibration.
[0031] This invention also discloses a method for using the anti-clogging self-cleaning compressor flue unblocking device, specifically including the following steps:
[0032] S1: The high-temperature exhaust gas containing tar and wood dust generated by the hot pressing of the press is sent into the connecting pipe through the smoke inlet pipe. An isolation net is set at the connection position between the smoke inlet pipe and the connecting pipe to prevent the oil and impurities that fall after being scraped by the cleaning component from falling into the inside of the smoke inlet pipe, thus avoiding blockage of the smoke inlet pipe; the purified flue gas is discharged through the top exhaust pipe, and the detached oil and impurities are discharged through the bottom slag discharge pipe. The shell constitutes the basic channel for flue gas circulation and impurity collection.
[0033] S2: During equipment operation, cleaning, crushing, and vibration are performed simultaneously. The hydraulic rod drives the piston rod, causing the cleaning head to reciprocate vertically up and down along the exhaust pipe, scraping and removing tar deposits against the pipe wall. The guide trough guides wastewater and debris, preventing impurities from accumulating and allowing the dirt to be transported downwards to the bottom of the connecting pipe. The cleaning head slides along the outer wall of the fixed spiral pipe, rotating due to the constraint of the spiral structure, achieving a combined lifting and rotating motion to continuously scrape the inner wall of the exhaust pipe circumferentially, eliminating cleaning dead zones.
[0034] S3: The high-pressure pump draws clean water and sends it into the fixed spiral tube through the water inlet pipe. It sprays out from the spiral array nozzle to form a rotating water curtain. It works with the cleaning head to flush the pipe wall, wash away the sticky tar, and prevent the oil stains from adhering again. The sewage and impurities fall into the bottom of the connecting pipe together.
[0035] S4: The drive motor rotates the transmission rod, and the power steering is achieved through the meshing of bevel gears. A set of power sources synchronously drives the crushing and vibration mechanisms. The second bevel gear drives the transmission sleeve, rotating head, and crushing blades to rotate; the piston rod passes through the transmission sleeve and slides in engagement, so the lifting and cleaning and bottom crushing actions do not interfere with each other. Falling agglomerated impurities are evenly dispersed into the working range of the crushing blades by contacting the conical surface of the rotating head. The inclined crushing blades rotate and shear, breaking tar clumps and wood powder into fine particles. This prevents the slag discharge pipe from clogging, and the protective cover prevents impurities from entering the transmission parts.
[0036] S5: The transmission rod synchronously drives the drive gear, which in turn drives the driven gear ring and hexagonal prism to rotate via the transmission gear set. The hexagonal prism reciprocates and impacts the bottom of the stress frame, transmitting high-frequency micro-amplitude vibrations to the connecting pipe. The buffer pads cushion the rigid impacts, preventing the shell from loosening. The vibration causes the debris attached to the pipe wall to continuously fall off, while preventing the crushed impurities from bridging and clogging the slag discharge pipe, ensuring that the impurities are smoothly collected and discharged.
[0037] In the scheme of this application:
[0038] 1. By using a hydraulic rod to drive the cleaning head to rise and rotate along a fixed spiral tube, and cooperating with a high-pressure pump to supply water to form a rotating water curtain, online scraping and flushing of the flue inner wall can be achieved without stopping the machine, cutting off the air supply, or cooling and depressurizing. This avoids high-risk operations in confined spaces and eliminates the need for complicated gas detection and safety protection systems. The entire cleaning structure is arranged inside the flue gas channel and is not coupled with the external walking mechanism, which effectively avoids the failure of the equipment caused by oil and dirt sticking to the power mechanism. It can operate stably for a long time and get rid of the limitation of traditional cleaning methods as only an emergency measure.
[0039] 2. Using a single drive motor as the power source, the crushing component is driven by bevel gear transmission to achieve simultaneous operation of scraping, rinsing and impurity crushing processes; the tar clumps that are cleaned and stripped can be crushed in time, breaking large tar and wood powder mixtures into fine particles, preventing large impurities from clogging the slag discharge pipe, forming a continuous processing flow of "scraping-rinsing-crushing-slag discharge". The equipment can run continuously with the press, adapting to the uninterrupted working rhythm of the continuous production line, solving the defect of traditional cleaning equipment that cannot match the continuous operation rhythm of the press;
[0040] 3. The drive motor synchronously drives the vibration component to work, transmitting high-frequency micro-amplitude vibration to the connecting pipe shell, which promotes the continuous shedding of debris attached to the pipe wall, while preventing the fine impurities after crushing from bridging and clogging at the slag discharge position, ensuring that the impurities are smoothly collected and discharged; the cleaning, rinsing, crushing and vibration processes work together, and multiple anti-clogging measures cooperate to further improve the reliability of the flue's self-cleaning.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and 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.
[0051] Example:
[0052] Please see Figure 1-8 This embodiment proposes an anti-clogging self-cleaning compressor flue unblocking device, including a connecting pipe 1, a flue pipe 11 installed at the top of the connecting pipe 1, a slag discharge pipe 13 installed at the bottom of the connecting pipe 1, a flue pipe 12 installed on one side of the connecting pipe 1, and an isolation net 14 installed at the connection position between the connecting pipe 1 and the flue pipe 12, and further including:
[0053] The inlet pipe 12 is connected to the exhaust pipe of the compressor. The high-temperature exhaust gas containing tar and wood powder enters the connecting pipe 1 through the inlet pipe 12. The exhaust pipe 11 serves as the exhaust channel for the purified flue gas, and the slag discharge pipe 13 serves as the centralized discharge outlet for the oil and debris generated during cleaning. The entire shell structure constitutes the basic carrier for flue gas circulation and impurity collection.
[0054] The cleaning assembly is located inside the connecting pipe 1 and is used to clean the inner walls of the connecting pipe 1 and the exhaust pipe 11. The cleaning assembly includes a hydraulic rod 2 installed at the bottom of the slag discharge pipe 13, a piston rod 21 sliding inside the hydraulic rod 2, a cleaning head 22 installed at the top of the piston rod 21, and a guide groove 23 opened on the outside of the cleaning head 22. The cleaning head 22 is slidably connected to the exhaust pipe 11 and is used to clean the inner wall of the exhaust pipe 11.
[0055] Hydraulic rod 2 serves as the lifting power source, driving piston rod 21 to move cleaning head 22 vertically up and down. The outer side of cleaning head 22 scrapes against the inner wall of exhaust pipe 11, removing tar deposits attached to the inner wall of exhaust pipe 11. During the lifting process, drainage channel 23 guides sewage and debris, preventing impurities from accumulating above cleaning head 22 and ensuring that the scraped dirt can be transported downwards to the bottom area of connecting pipe 1.
[0056] A guide assembly is disposed inside the exhaust pipe 11 to guide the cleaning end of the cleaning assembly, allowing the cleaning end to rotate and assisting in cleaning the inner wall of the exhaust pipe 11. The guide assembly includes a fixing ring 3 fixedly installed on the inner top of the exhaust pipe 11 and a spiral tube 31 fixedly installed on the bottom of the fixing ring 3. The spiral tube 31 is fixed to the inner side of the exhaust pipe 11 by the fixing ring 3, and the spiral tube 31 itself does not move or rotate. The spiral tube 31 is slidably connected to the cleaning head 22.
[0057] The fixing ring 3 provides a stable mounting point for the spiral tube 31, rigidly fixing the spiral tube 31 inside the exhaust pipe 11; when the cleaning head 22 slides up and down along the outer wall of the fixed spiral tube 31, it is constrained by the wall surface of the spiral tube 31 and generates a rotational motion, realizing a composite motion of lifting and rotating, forming a continuous circumferential scraping of the inner wall of the exhaust pipe 11, eliminating cleaning dead corners, and improving the cleaning coverage of the inner wall of the exhaust pipe 11.
[0058] The water spray assembly is located on the outside of the connecting pipe 1. It works in conjunction with the guide assembly to help discharge the cleaned oil and impurities. The water spray assembly includes multiple nozzles 32 on the spiral pipe 31, a fixing frame 35 installed on the outside of the middle end of the exhaust pipe 11, a high-pressure pump 34 installed on the fixing frame 35, and a water inlet pipe 33 installed at the output end of the high-pressure pump 34. The water inlet pipe 33 passes through the fixing ring 3 and is connected to the spiral pipe 31.
[0059] The mounting bracket 35 provides an installation base for the high-pressure pump 34. The high-pressure pump 34 draws in external clean water and delivers it to the interior of the fixed spiral tube 31 through the water inlet pipe 33. The water flow is finally sprayed outward from the nozzle 32 on the inner wall of the spiral tube 31. The water spray assembly cooperates with the rotating cleaning head 22. The water flow washes away the sticky tar that has been peeled off by the scraper, preventing the oil stains from adhering to the inner wall of the tube again.
[0060] Multiple nozzles 32 are arranged in a spiral array along the inner wall of the spiral tube 31. When the high-pressure water is sprayed out through the fixed spiral tube 31, it forms a rotating water curtain, which, together with the lifting and lowering motion of the cleaning head 22, washes the oil stains adhering to the inner wall of the exhaust pipe 11.
[0061] The spirally arranged nozzles 32 create a swirling effect in the direction of the high-pressure water jet. The rotating water curtain can follow the rise and fall of the cleaning head 22 to synchronously flush the inner wall of the exhaust pipe 11, which enhances the flushing effect on tar-sticky pollutants. The wastewater and impurities generated during flushing flow downwards into the bottom of the connecting pipe 1, providing conditions for subsequent crushing and slag removal processes.
[0062] The drive assembly is located on one side of the bottom of the connecting pipe 1 to provide power support for the operation of the bottom structure. The drive assembly includes a fixed sleeve 4 installed on the outside of the connecting pipe 1, a drive motor 41 installed on the outside of the fixed sleeve 4, a transmission rod 42 installed on the output end of the drive motor 41, a first bevel gear 43 installed on the end of the transmission rod 42, and a second bevel gear 44 located at the bottom of the first bevel gear 43.
[0063] The fixed sleeve 4 serves as the mounting base for the entire drive and vibration structure. After the drive motor 41 starts, it drives the transmission rod 42 to rotate. The power is transmitted through the meshing of the first bevel gear 43 and the second bevel gear 44, providing rotational power to the bottom crushing component and the vibration component simultaneously. This enables a single power source to drive multiple cleaning functions and simplifies the equipment drive structure.
[0064] The crushing component is located inside the connecting pipe 1 and is driven by the drive component to crush and discharge oil and impurities. The crushing component includes a support frame 54 installed inside the bottom of the connecting pipe 1, a protective cover 53 installed on the top of the support frame 54, a transmission sleeve 5 rotating on the top of the support frame 54, a rotating head 51 installed on the top of the transmission sleeve 5, and a crushing blade 52 installed on the outside of the rotating head 51. The piston rod 21 passes through the support frame 54, the transmission sleeve 5, and the rotating head 51 and is slidably connected to the support frame 54, the transmission sleeve 5, and the rotating head 51.
[0065] The support frame 54 is fixed inside the connecting pipe 1 to provide rotational support for the transmission sleeve 5. The protective cover 53 prevents sewage and debris from entering the transmission engagement position. The second bevel gear 44 drives the transmission sleeve 5 to rotate, thereby driving the rotating head 51 and the crushing blade 52 to rotate synchronously. The piston rod 21 passes through the center of the transmission sleeve 5 and slides in fit, without interfering with each other. The lifting and cleaning action and the bottom crushing action can operate synchronously and independently.
[0066] The top of the rotating head 51 is set as a conical structure, and the crushing blades 52 are arranged in an inclined manner around the outside of the rotating head 51. After the falling agglomerated impurities come into contact with the conical surface, they are dispersed to the surroundings and crushed by the rotating crushing blades 52.
[0067] The conical structure acts as a guide, preventing large tar clumps from accumulating at the center of the rotating head 51 and dispersing them evenly within the working range of the crushing blade 52. The inclined crushing blade 52 forms a shearing and crushing zone when rotating, breaking the tar and wood powder mixture into fine particles, preventing large impurities from clogging the slag discharge pipe 13, and ensuring that impurities are continuously and stably discharged.
[0068] A vibration assembly, located on the outside of the connecting pipe 1, assists in cleaning and discharging impurities through the generated vibration. The vibration assembly includes a limiting plate 6 mounted on the top of the fixed sleeve 4, a driving gear 61 mounted on the outside of the transmission rod 42, a transmission gear set 62 located on the inside of the limiting plate 6, a hexagonal prism 63 rotating on the top inside of the limiting plate 6, a driven gear ring 64 mounted on the middle end of the hexagonal prism 63, and a stress frame 65 mounted on the outside of the connecting pipe 1. The driving gear 61 meshes with the bottom of the transmission gear set 62, and the top of the transmission gear set 62 meshes with the driven gear ring 64. The hexagonal prism 63 is slidably connected to the stress frame 65.
[0069] When the transmission rod 42 rotates continuously, it synchronously drives the drive gear 61 to rotate. After the transmission gear set 62 reduces speed and increases torque, it drives the driven gear ring 64 to rotate, which in turn drives the hexagonal prism 63 (the hexagonal prism 63 itself is made of flexible and wear-resistant material) to rotate continuously. During the rotation, the hexagonal prism 63 continuously impacts the bottom of the stress frame 65 with its own shape, and transmits the vibration to the housing of the connecting pipe 1 through the stress frame 65. The vibration causes the impurities attached to the inner wall to fall off, while preventing the crushed debris from bridging and blocking at the slag discharge pipe 13.
[0070] A buffer pad is installed on the side of the stress frame 65 near the connecting pipe 1. The buffer pad abuts against the outer wall of the connecting pipe 1. When the hexagonal prism 63 slides up and down, the stress frame 65 drives the connecting pipe 1 to generate high-frequency micro-amplitude vibration.
[0071] The buffer pad can not only stably transmit vibration, but also buffer the rigid impact between the stress frame 65 and the connecting pipe 1, avoiding the loosening of the shell connection position due to long-term vibration; the high-frequency micro-amplitude vibration continuously acts on the pipe wall of the connecting pipe 1, causing the adhering tar debris to continuously fall off, while ensuring that the crushed impurities smoothly collect to the slag discharge pipe 13.
[0072] S1: The high-temperature exhaust gas containing tar and wood dust generated by the hot pressing of the press is sent into the connecting pipe 1 through the smoke inlet pipe 12. The isolation net 14 is set at the connection position between the smoke inlet pipe 12 and the connecting pipe 1 to prevent the oil and impurities that fall after being scraped by the cleaning component from falling into the inside of the smoke inlet pipe 12, thus avoiding blockage of the smoke inlet pipe 12. The purified flue gas is discharged through the top exhaust pipe 11, and the stripped oil and impurities are discharged from the bottom slag discharge pipe 13. The shell constitutes the basic channel for flue gas circulation and impurity collection.
[0073] S2: During equipment operation, cleaning, crushing, and vibration operations are carried out simultaneously. Hydraulic rod 2 drives piston rod 21, causing cleaning head 22 to vertically reciprocate up and down along exhaust pipe 11, scraping and removing tar deposits against the pipe wall; drainage channel 23 guides wastewater and debris, preventing impurities from accumulating and allowing dirt to be transported downwards to the bottom of connecting pipe 1. Cleaning head 22 slides along the outer wall of fixed spiral pipe 31, rotating under the constraint of the spiral structure, achieving a combined lifting and rotating motion, continuously scraping the inner wall of exhaust pipe 11 circumferentially to eliminate cleaning dead angles;
[0074] S3: High-pressure pump 34 draws clean water and sends it into fixed spiral tube 31 through water inlet pipe 33. It sprays out from spiral array nozzle 32 to form a rotating water curtain. It works with cleaning head 22 to flush the pipe wall and wash away sticky tar to prevent oil stains from adhering again. Sewage and impurities fall into the bottom of connecting pipe 1 together.
[0075] S4: Drive motor 41 drives transmission rod 42 to rotate, and power steering is achieved through bevel gear meshing. A set of power sources synchronously drives the crushing and vibration mechanism. Second bevel gear 44 drives transmission sleeve 5, rotating head 51 and crushing blade 52 to rotate; piston rod 21 passes through transmission sleeve 5 and slides in cooperation, so the lifting and cleaning and bottom crushing actions do not interfere with each other. Falling clumps of impurities contact the conical surface of rotating head 51 and are evenly dispersed into the working range of crushing blade 52. The inclined crushing blade 52 rotates and shears, breaking tar clumps and wood powder into fine particles, preventing the slag discharge pipe 13 from being blocked, and the protective cover 53 prevents impurities from entering the transmission part.
[0076] S5: The transmission rod 42 synchronously drives the drive gear 61, which in turn drives the driven gear ring 64 and hexagonal prism 63 to rotate via the transmission gear set 62. The hexagonal prism 63 reciprocates and impacts the bottom of the stress frame 65, transmitting high-frequency micro-amplitude vibrations to the connecting pipe 1. The buffer pad cushions the rigid impact, preventing the shell from loosening. The vibration causes the debris attached to the pipe wall to continuously fall off, while preventing the crushed impurities from bridging and clogging in the slag discharge pipe 13, ensuring that the impurities are smoothly collected and discharged.

The buffer pad abuts against the outer wall of the connecting pipe (1). When the hexagonal prism (63) slides up and down, the stress frame (65) drives the connecting pipe (1) to generate high-frequency micro-amplitude vibration.
10. The method of using the anti-clogging self-cleaning compressor flue unblocking device according to any one of claims 1-9, characterized in that, Specifically, the following steps are included: S1: The high-temperature exhaust gas containing tar and wood dust generated by the hot pressing of the press is sent into the connecting pipe (1) through the smoke inlet pipe (12). The isolation net (14) is set at the connection position between the smoke inlet pipe (12) and the connecting pipe (1) to prevent the oil and dirt impurities that fall after being scraped by the cleaning component from falling into the inside of the smoke inlet pipe (12) and avoid the smoke inlet pipe (12) from becoming blocked. The purified flue gas is discharged through the top exhaust pipe (11), and the stripped oil and dirt impurities are discharged from the bottom slag discharge pipe (13). The shell constitutes the basic channel for flue gas circulation and impurity collection. S2: During equipment operation, cleaning, crushing, and vibration operations are carried out simultaneously. The hydraulic rod (2) drives the piston rod (21) to move the cleaning head (22) vertically up and down along the exhaust pipe (11), scraping and peeling off tar deposits against the pipe wall; the guide groove (23) guides sewage and debris, preventing the accumulation of impurities, and allowing the dirt to be transported downwards to the bottom of the connecting pipe (1). The cleaning head (22) slides along the outer wall of the fixed spiral pipe (31), and rotates due to the constraint of the spiral structure, realizing a combined motion of lifting and rotating, continuously scraping the inner wall of the exhaust pipe (11) in the circumference, eliminating cleaning dead corners; S3: The high-pressure pump (34) draws clean water and sends it into the fixed spiral tube (31) through the water inlet pipe (33). It sprays out from the spiral array nozzle (32) to form a rotating water curtain. It works with the cleaning head (22) to flush the pipe wall, wash away the sticky tar, prevent the oil stains from adhering again, and the sewage and impurities fall into the bottom of the connecting pipe (1). S4: The drive motor (41) drives the transmission rod (42) to rotate, and the power steering is achieved through the meshing of bevel gears. A set of power sources synchronously drives the crushing and vibration mechanism. The second bevel gear (44) drives the transmission sleeve (5), the rotating head (51) and the crushing blade (52) to rotate; the piston rod (21) passes through the transmission sleeve (5) and slides, so the lifting and cleaning and the bottom crushing action do not interfere with each other. The falling clumps of impurities are evenly dispersed into the working range of the crushing blade (52) by contacting the cone surface of the rotating head (51). The inclined crushing blade (52) rotates and shears, breaking the tar clumps and wood powder into fine particles, preventing the slag discharge pipe (13) from being blocked, and the protective cover (53) prevents impurities from entering the transmission part; S5: The transmission rod (42) synchronously drives the drive gear (61), which in turn drives the driven gear ring (64) and hexagonal prism (63) to rotate via the transmission gear set (62). The hexagonal prism (63) reciprocates and impacts the bottom of the stress frame (65), transmitting high-frequency micro-amplitude vibration to the connecting pipe (1). The buffer pad buffers the rigid impact and prevents the shell from loosening. The vibration causes the debris attached to the pipe wall to continuously fall off, while preventing the crushed impurities from bridging and clogging in the slag discharge pipe (13), ensuring that the impurities are smoothly collected and discharged.
