[0045] The collecting box 2 includes a box body 201, in which an intermediate plate 202 is arranged, and the intermediate plate 202 divides the box body 201 into a large particle chamber 203 and a small particle chamber 204. The front sides of the large particle chamber 203 and the small particle chamber 204 are both provided with material taking doors for taking materials; the top of the large particle chamber 203 is provided with a feeding hole; the small particle chamber 204 is connected to the bottom of the guide pipe 13, and a baffle plate 8 is arranged in the small particle chamber 204 for isolating the lighter particles from being discharged to the outside; one side of the small particle chamber 204 is connected to a shunt pipe 14, and the other end of the shunt pipe 14 is connected to another external vacuum pump.

[0046] In this embodiment, the external vacuum pump works to form a negative pressure in the vacuum pipe 3 and the separation box 1, and the industrial exhaust gas is sucked into the separation box 1 through the air inlet pipe 101 in a tangential direction; due to the tangential entry, the exhaust gas inside the separation box 1 produces a strong rotational motion, and the generated centrifugal force pushes the heavier particles to the wall of the separation box 1, and finally falls into the large particle cavity 203 in the collection box 2 through the feed hole, completing the preliminary separation of the exhaust gas;

[0047] The exhaust gas after preliminary separation will enter the separation component 4 and finally be discharged outward through the exhaust pipe 3. The separation component 4 can separate the lighter particles in the exhaust gas and complete the secondary separation of the exhaust gas;

[0048] Specifically, during the process of re-separation of the exhaust gas, the exhaust gas after the initial separation carries lighter particles into the air inlet cavity through the air inlet hole, and the filter 502 can block the lighter particles at the bottom of the filter assembly 5. The clean gas after passing through the filter 502 will enter the exhaust pipe 3 and be discharged outward; the driving device 6 drives the filter assembly 5 to rotate, and the lighter particles affected by the wind will always be adsorbed on the bottom of the filter assembly 5 by the wind and move with the rotation of the filter assembly 5 until they pass through the feed channel and enter the discharge cavity;

[0049] Through the shunt pipe 14, the external air pump connected to the shunt pipe 14 will form a negative pressure in the small particle chamber 204 in the collection box 2, so that the clean gas filtered by the filter assembly 5 will be introduced into the discharge chamber through the connecting pipe 12, and pass through the filter assembly 5 from top to bottom in the discharge chamber, and the particles adsorbed on the bottom of the filter assembly 5 will be blown downward to the guide pipe 13 and introduced into the small particle chamber 204, and the baffle plate 8 will prevent the lighter particles from being discharged outward, so that the lighter particles are collected in the small particle chamber 204; in addition, the airflow from top to bottom in the discharge chamber also has the effect of cleaning the filter assembly 5, so that the filter assembly 5 can be self-cleaning when in use;

[0050] Part of the gas in the air inlet cavity will also enter the discharge cavity through the feed channel. This airflow will carry the lighter particles directly into the discharge cavity and lead them into the small particle cavity 204 in the collection box 2 for classification and collection.

[0051] Preferably, the filter assembly 5 includes an outer ring 501, an inner wall of the circular plate 401 is provided with an annular groove, and the outer ring 501 is rotatably arranged in the annular groove; the inner wall of the outer ring 501 is provided with a filter 502 for filtering lighter particles;

[0052] The driving device 6 includes a driving rod 601, the two ends of which are rotatably arranged on both sides of the inner wall of the circular plate 401, and a fan blade 602 is fixedly sleeved on the driving rod 601; the airflow in the connecting pipe 12 acts on the fan blade 602 to drive the driving rod 601 to rotate; an upper bevel gear 603 is fixedly sleeved on the driving rod 601, a support frame 605 is fixedly connected to the inner wall of the circular plate 401, a transmission rod 604 is rotatably arranged on the support frame 605, a lower bevel gear 606 meshing with the upper bevel gear 603 is fixedly connected to the top of the transmission rod 604, and a driving tooth 607 is fixedly connected to the bottom of the transmission rod 604;

[0053] The inner wall of the outer ring 501 is provided with a tooth groove 503 adapted to the driving tooth 607, and the tooth groove 503 is located on the upper side of the filter screen 502;

[0054] In this embodiment, the external vacuum pump connected to the diversion pipe 14 will cause a negative pressure to form in the small particle chamber 204 in the collecting box 2, so that the clean gas filtered in the vacuum pipe 3 will be introduced into the discharge chamber through the connecting pipe 12, and pass through the filter assembly 5 from top to bottom in the discharge chamber; in this process, the airflow from top to bottom will act on the fan blades 602 to drive the drive rod 601 to rotate, and the drive rod 601 drives the transmission rod 604 to rotate through the upper bevel gear 603 and the lower bevel gear 606, and the transmission rod 604 drives the drive tooth 607 to rotate, thereby driving the outer ring 501 to rotate, and then driving the filter 502 to rotate; so that the drive device 6 can drive the filter assembly 5 to rotate.

[0055] Preferably, an exhaust pipe 15 is provided at the top of the discharge chamber, the exhaust pipe 15 is connected to the connecting pipe 12, and a flat exhaust nozzle is provided at the bottom of the exhaust pipe 15, and the exhaust direction of the exhaust nozzle is toward the driving rod 601;

[0056] Specifically, the gas entering the discharge chamber through the connecting pipe 12 will enter the exhaust pipe 15, and be discharged to the fan blades 602 on the driving rod 601 through the exhaust nozzle at the bottom of the exhaust pipe 15; since the exhaust nozzle is flat, the airflow flowing through the exhaust nozzle can be compressed, thereby increasing the discharge velocity of the airflow; with the increase in the airflow velocity, the force acting on the fan blades 602 is also increased, thereby stably pushing the fan blades 602 to rotate.

[0057] Preferably, a scraping component 7 is also provided in the discharge chamber;

[0058] The scraping assembly 7 includes a fixed shaft 701, which is fixedly mounted on one side of the lower partition 403.

A return spring 7023 is arranged in the retraction groove 7021. One end of the return spring 7023 is connected to the block 7022, and the other end is connected to the inner wall of the retraction groove 7021. A reset assembly 703 for limiting the rotation angle of the scraper rod 702 and driving the scraper rod 702 to reset is arranged at the bottom of the fixed shaft 701.

[0059] An annular slide groove 504 is provided on the inner wall of the outer ring 501, and the clamping block 7022 slides along the slide groove 504; at least two groups of shifting blocks 5041 are arranged in the slide groove 504, and the two groups of shifting blocks 5041 are arranged equidistantly;

[0060] In this embodiment, the driving device 6 drives the outer ring 501 to rotate. After the outer ring 501 rotates, the shift block 5041 set in the slide groove 504 will drive the block 7022 to move with the shift block 5041, and then drive the scraper rod 702 to rotate synchronously with the rotation of the filter screen 502; when the scraper rod 702 rotates to a certain angle, the reset component 703 will limit the scraper rod 702 from continuing to rotate. At this time, as the shift block 5041 continues to move, the block 7022 will retract into the retraction groove 7021 until the block 7022 completely passes through the shift block 5041. The reset spring 7023 will push the block 7022 to be inserted into the slide groove 504 again. At the same time, the reset component 703 will drive the scraper rod 702 to reset. During the resetting process, the scraper rod 702 rotates in the opposite direction to the filter screen 502, so that the particles stuck to the bottom of the filter screen 502 can be scraped off.

[0061] Preferably, the reset assembly 703 includes a shell 7031, which is fixedly arranged at the bottom of the fixed shaft 701, and a rotating rod 7032 is rotatably arranged in the shell 7031, and the top of the rotating rod 7032 is connected to the bottom of one end of the scraper rod 702, and the rotating rod 7032 is driven to rotate when the scraper rod 702 moves; a torsion spring 7033 is also arranged in the shell 7031, and the torsion spring 7033 is sleeved on the outer periphery of the rotating rod 7032, and one end of the torsion spring 7033 is connected to the inner wall of the shell 7031, and the other end is connected to the outer periphery of the rotating rod 7032;

[0062] A transmission block 7034 is rotatably provided at the bottom of the housing 7031. The transmission block 7034 is connected to the rotating rod 7032.

A limit block 7035 is also fixedly provided at the bottom of the housing 7031.

[0063] Specifically, the driving device 6 drives the outer ring 501 to rotate. After the outer ring 501 rotates, the shift block 5041 set in the slide groove 504 will drive the block 7022 to move with the shift block 5041, and then drive the scraper rod 702 to rotate; the rotation of the scraper rod 702 will drive the rotating rod 7032 to rotate synchronously and compress the torsion spring 7033 to generate energy storage; at the same time, the rotating rod 7032 will drive the transmission block 7034 to rotate synchronously, and when the limit plate 7036 on the transmission block 7034 moves to the limit block 7035, the limit block 7035 will prevent the transmission block 7034 from continuing to move, thereby preventing the scraper rod 702 from continuing to move; when the scraper rod 702 completely passes through the shift block 5041, the energy storage of the torsion spring 7033 is released, and the scraper rod 702 is driven to rotate in the opposite direction through the rotating rod 7032 to reset. During the resetting process, the scraper rod 702 rotates in the opposite direction to the filter screen 502 to scrape off the particles adhered to the bottom of the filter screen 502.

[0064] Preferably, a circular hole is provided on the baffle plate 8, and a second filter screen 801 is provided on the inner wall of the circular hole to block the passage of lighter particles, and the second filter screen 801 is elastic; a transverse plate 11 is also provided in the small particle cavity 204, one side of the transverse plate 11 is fixedly connected to the middle plate 202, and the other side is fixedly connected to the baffle plate 8; a cleaning component 9 is provided on a side of the middle plate 202 close to the second filter screen 801, and the cleaning component 9 includes a drive motor 901, and the drive motor 901 is fixedly provided The output end of the driving motor 901 is provided with a shaft 902, and the end of the shaft 902 is provided with a scraper 903 for scraping the second filter screen 801. The scraper 903 abuts against the second filter screen 801 and causes the surface of the second filter screen 801 at the abutment of the scraper 903 to be elastically deformed toward a side away from the driving motor 901. When the scraper 903 rotates to the area of ​​the horizontal plate 11, the space margin generated by the elastic deformation allows the scraper 903 to pass over the horizontal plate 11.

[0065] In this embodiment, the second filter 801 on the baffle plate 8 will prevent particles from entering the diversion pipe 14 and being discharged outward, and the airflow entering the small particle cavity 204 will be discharged to the diversion pipe 14 through the second filter 801 on the upper side of the transverse plate 11; the drive motor 901 is started to drive the shaft 902 to reciprocate 300°, and drive the scraper 903 to reciprocate 300° along the surface of the second filter 801, so that all the particles adsorbed on the second filter 801 are scraped into the lower side of the transverse plate 11. The transverse plate 11 can reduce the diffusion amount of the scraped particles to the upper side of the transverse plate 11, thereby ensuring the efficiency of the airflow entering the small particle cavity 204 to be discharged to the diversion pipe 14 through the second filter 801 on the upper side of the transverse plate 11.

[0066] Preferably, a trigger assembly 10 for triggering the drive motor 901 is also provided on the baffle plate 8; the trigger assembly 10 includes a piston rod 1001, the piston rod 1001 passes through the baffle plate 8 and is slidably connected to the baffle plate 8, a traction spring 1002 is connected between the piston rod 1001 and the middle plate 202, and a pressure plate 1004 is provided on the top of the piston rod 1001; a pressure sensor 1003 corresponding to the position of the pressure plate 1004 is provided on the baffle plate 8, and the pressure sensor 1003 is connected to the external control system to control the opening and closing of the drive motor 901;

[0067] In this embodiment, when in use, the second filter 801 on the baffle plate 8 will prevent particles from entering the shunt pipe 14 and being discharged outward, and the airflow entering the small particle chamber 204 will be discharged to the shunt pipe 14 through the second filter 801 on the upper side of the cross plate 11; as the particles adsorbed on the second filter 801 gradually increase, the ventilation volume through the second filter 801 will gradually decrease, causing the pressure difference in the chambers on both sides of the baffle plate 8 to increase, and the piston rod 1001 will move under the influence of the pressure difference, driving the pressure plate 1004 to gradually approach the pressure sensor 1003 until the pressure plate 1004 is completely pressed on the pressure sensor 1003, triggering the pressure sensor 1003 to start and send a working signal to the drive motor 901 through the external control system. After receiving the working signal, the drive motor 901 drives the scraper 903 to reciprocate 300° and automatically closes after working several times. At this time, the particulate matter adsorbed on the second filter 801 is reduced, the ventilation volume through the second filter 801 will increase, the air pressure difference on both sides of the baffle plate 8 will be reduced, and the traction spring 1002 will drive the piston rod 1001 to reset, thereby releasing the contact between the pressure plate 1004 and the pressure sensor 1003.
