[0016] The beneficial effects of this invention are: 1) The exhaust assembly of this device is connected to the filter element. Air enters the connecting pipe from the air collection pipe, is filtered by the filter element, and is discharged from the exhaust assembly. The filtered dust falls into the dust collection box. With the cooperation of the sealing component and the discharge component, the dust collected in the dust collection box is discharged from both ends of the dust collection box, ensuring that the device can work continuously and improving the efficiency of dust treatment.

[0017] 2) The fixing parts of this device are used to fix the collection box, ensuring that the collection box is fixed at the bottom of the gas collection pipe through hole, and ensuring that the collection box can collect the dust initially filtered by the filter mechanism, thereby improving the dust treatment efficiency. Insert the flange on the collection box into the limiting groove in the mounting groove, so that the second limiting hole on the flange corresponds to the first limiting hole on the limiting groove. Then, insert the limiting pin into the first limiting hole and the second limiting hole, thereby achieving the purpose of fixing the collection box.

[0018] 3) The motor of this device drives the first pulley to rotate. The rotation of the first pulley drives the second pulley to rotate via the first belt. The rotation of the second pulley drives the rotating shaft to rotate. The rotation of the rotating shaft drives the fan blades to rotate. The rotation of the fan blades achieves the purpose of extracting air from the connecting pipe. When the pressure in the connecting pipe is lower than atmospheric pressure, the gas will enter the gas collecting pipe from the air inlet hopper. After being filtered by the upper and lower filter plates, it enters the connecting pipe from the fixed pipe. After secondary filtration by the filter cylinder, the treated gas is discharged from the fan hood.

[0019] 4) The second pulley of this device drives the fifth pulley to rotate via the third belt. The rotation of the fifth pulley will drive the mounting shaft to rotate, which in turn will drive the first gear and the connecting rod to rotate. The second gear will then rotate along the first gear and will also rotate on its own axis. During the rotation of the second gear, one end of the rotating arm will rotate. While the other end of the rotating arm rotates around the fixed shaft, it can also push the upper slide plate, lower slide plate, pusher plate and unloading plate to reciprocate in the dust collection box, thereby discharging the dust in the dust collection box from the end of the dust collection box.

[0020] 5) The sealing components of this device are used to seal both ends of the dust collection box to prevent air from entering from both ends of the dust collection box during operation. When the upper slide plate, lower slide plate, pusher plate, and discharge plate move towards one end of the dust collection box, the discharge plate and lifting plate work together to lift the sealing plate upward. Under the action of the pusher plate, the dust inside the dust collection box is discharged from the bottom of the sealing plate to the outside of the dust collection box. During the sliding of the upper slide plate, the upper slide plate will seal the connection between the connecting pipe and the dust collection box to prevent air from entering the dust collection box from the dust discharge end, thus ensuring the dust removal efficiency and quality of the device.

Figure 10As shown, the top of the collection box 10 is provided with a flange 1001, which cooperates with the limiting groove 707 to prevent the collection box 10 from falling off the air collection pipe 7 during operation, ensuring that the collection box 10 can collect the dust filtered out by the filter mechanism 6. The fixing member 5 is provided on the air collection pipe 7 and is used to fix the collection box 10 to the bottom of the air collection pipe 7.

[0045] The flange 1001 is designed to allow the collection box 10 to be secured in the limiting groove 707, facilitating the installation and removal of the collection box 10 and greatly improving the working efficiency of the device.

[0046] In this embodiment, as Figure 8 , Figure 9 As shown, the fixing component 5 includes a column 501, a guide column 507, a lifting plate 503, a lifting rod 506, a first spring 508, a handle 505, and a limiting column 5010. The column 501 is fixedly installed on the top of the collection box 10. A stop block 502 is provided on the top of the column 501. The stop block 502 can limit the movement range of the lifting plate 503 on the column 501, ensuring the normal operation of the lifting plate 503.

[0047] Guide columns 507 are symmetrically arranged on both sides of the center line of column 501. Lifting plate 503 is slidably installed on column 501 and guide columns 507. The guide columns 507 are used to guide the lifting of lifting plate 503, prevent lifting plate 503 from rotating during operation, and ensure the normal operation of lifting plate 503.

[0048] The first spring 508 is sleeved on the column 501 and is located between the lifting plate 503 and the collection box 10. The first spring 508 is provided to provide the lifting plate 503 with upward movement power at all times, ensuring that the limiting post 5010 on the bend 509 at the bottom of the lifting rod 506 can always be inserted into the first limiting hole 705 and the second limiting hole 1002, thus ensuring the stability and safety of the collection box 10 during operation.

[0049] A protrusion 504 is provided at both ends of one side of the lifting plate 503. The top of the lifting rod 506 is rotatably mounted on the protrusion 504. The two ends of the handle 505 are respectively fixedly mounted on the lifting rod 506 on the protrusion 504 at both ends of one side of the lifting plate 503. The handle 505 is provided to facilitate pulling the lifting rod 506, thereby pulling the limiting post 5010 out of the first limiting hole 705 and the second limiting hole 1002. A bend 509 is provided at the bottom of the lifting rod 506. The limiting post 5010 is set on the bend 509. The bend 509 ensures the safety and stability of the limiting post 5010 during operation.

[0050] A first limiting hole 705 is provided on the side wall of the limiting groove 707, and a second limiting hole 1002 corresponding to the first limiting hole 705 is provided on the flange 1001. The limiting post 5010 cooperates with the first limiting hole 705 and the second limiting hole 1002.

[0051] The work process is as follows: When fixing the collection box 10, insert the flange 1001 on the top of the collection box 10 into the limiting groove 707, so that the first limiting hole 705 on the limiting groove 707 corresponds to the second limiting hole 1002 on the flange 1001. Pull the handle 505 down to drive the lifting rod 506 and the lifting plate 503 to move downward. The downward movement of the lifting plate 503 will compress the first spring 508. The downward movement of the lifting rod 506 will drive the bending 509 and the limiting post 5010 to move downward. The downward movement of the limiting post 5010 will align the limiting post 5010 with the first limiting hole 705. Stop pulling the handle 505. Under the action of the first spring 508, the lifting plate 503 will move upward, which will drive the lifting rod 506 and the limiting post 5010 to move upward, so that the limiting post 5010 is inserted into the first limiting hole 705 and the second limiting hole 1002, thereby fixing the collection box 10.

[0052] When disassembling the collection box 10, simply pull down the handle 505 to move the lifting plate 503, lifting rod 506 and limiting post 5010 downwards, so that the limiting post 5010 is pulled out from the first limiting hole 705 and the second limiting hole 1002, and then the collection box 10 is pulled out from the limiting groove 707.

[0053] In this embodiment, as Figure 4 , Figure 5 , Figure 6 As shown, the exhaust assembly 2 includes a fan shroud 201, fan blades 208, a rotating shaft 206, a first pulley 204, a second pulley 207, a first belt 205, and a motor 203.

[0054] The rotating shaft 206 is disposed inside the connecting pipe 8 and is rotatably mounted on the connecting pipe 8. The fan blade 208 is fixedly mounted on the rotating shaft 206 and is located inside the fan cover 201. The second pulley 207 is fixedly mounted on the rotating shaft 206 and is connected to the first pulley 204 through the first belt 205.

[0055] The motor 203 drives the first pulley 204 to rotate. The first pulley 204 drives the second pulley 207 to rotate via the first belt 205. The rotation of the second pulley 207 will drive the rotating shaft 206 to rotate. The rotation of the rotating shaft 206 will drive the fan blade 208 to rotate. The rotation of the fan blade 208 will draw out the air in the connecting pipe 8, making the air pressure in the connecting pipe 8 lower than the atmospheric pressure.

[0056] In this embodiment, as Figure 6 , Figure 7 As shown, the filter element 9 includes a filter cylinder 901, a connecting rod 902, and a connecting ring 903. A through hole 905 is opened at one end of the filter cylinder 901. The connecting ring 903 is fixedly installed in the through hole 905 and is rotatably engaged with the connecting pipe 8. The connecting ring 903 is located inside the air cover 201. The rotating shaft 206 is set inside the filter cylinder 901. The setting of the connecting ring 903 can seal the connection between the connecting pipe 8 and the filter cylinder 901, preventing air from leaking out from the connection between the filter cylinder 901 and the connecting pipe 8, thus ensuring the efficiency and quality of dust removal in the air.

[0057] The connecting rod 902 is fixedly installed on the rotating shaft 206 and is fixedly connected to the inner wall of the filter cylinder 901. The connecting rod 902 ensures that the filter cylinder 901 rotates with the rotating shaft 206. During the rotation of the filter cylinder 901, the outer wall of the filter cylinder 901 will cooperate with the arc plate 904. The arc plate 904 can scrape off the dust stuck on the outer wall of the filter cylinder 901, preventing dust from clogging the filter holes on the filter cylinder 901 and ensuring the normal operation of the filter cylinder 901.

[0058] An arc-shaped plate 904 is also provided on the side wall of the connecting pipe 8. The arc-shaped plate 904 is used to scrape off the dust on the outer wall of the filter cylinder 901.

[0059] Air enters from the air collecting pipe 7 into the connecting pipe 8, and after being filtered by the filter cartridge 901, the air enters the interior of the filter cartridge 901. Under the action of the fan blades 208, the air is discharged from the fan cover 201, thereby achieving the purpose of collecting and treating dust in the air.

[0060] In this embodiment, as Figure 11 , Figure 12As shown, a filter mechanism 6 is installed inside the air collecting pipe 7. The filter mechanism 6 includes a drive motor 601, a third pulley 602, a fourth pulley 608, a second belt 607, a rotating shaft 6011, a sliding member 606, a rotating rod 603, and a connecting column 609. The drive motor 601 is located at the top of the air collecting pipe 7. The third pulley 602 is fixedly mounted on the output shaft of the drive motor 601. The rotating shaft 6011 is symmetrically arranged on both sides of the center line of the air collecting pipe 7, and the rotating shaft 6011 rotates... The rotating arm 4012 is movably mounted on the gas collecting pipe 7. The fourth pulley 608 is fixedly mounted on the rotating shaft 6011 and is connected to the third pulley 602 via the second belt 607. The rotating rod 603 is symmetrically arranged on both sides of the center line of the gas collecting pipe 7, and one end of the rotating rod 603 is fixedly mounted on the rotating shaft 6011. The connecting column 609 is fixedly mounted on the other end of the rotating arm 4012. The sliding member 606 is slidably disposed inside the gas collecting pipe 7 and the connecting column 609 cooperates with the sliding member 606.

[0061] The drive motor 601 drives the third pulley 602 to rotate. The third pulley 602 drives the fourth pulley 608 to rotate via the second belt 607. The rotation of the fourth pulley 608 drives the rotating shaft 6011 to rotate. The rotation of the rotating shaft 6011 drives the rotating rod 603 to rotate. The rotation of the rotating rod 603 drives the connecting column 609 to rotate. The rotation of the connecting column 609 drives the sliding member 606 to reciprocate along the air collecting pipe 7.

[0062] In this embodiment, as Figure 11 , Figure 13 As shown, the sliding member 606 includes an upper filter plate 6013, a lower filter plate 6017, a first sliding plate 6014, a second sliding plate 6012, an inclined plate 6016, and a connecting plate 6019. A first slide rail 604 and a second slide rail 605 are provided on the side wall of the air collection pipe 7. The inclined plate 6016 is symmetrically arranged at both ends of the upper filter plate 6013 and the lower filter plate 6017, and both ends of the inclined plate 6016 are fixedly connected to the upper filter plate 6013 and the lower filter plate 6017, respectively. The inclined plate 6016 is used to guide the dust scraped off by the fixed plate 6010 and transport the dust into the collection box 10.

[0063] The first slide plate 6014 is symmetrically arranged on both sides of the upper filter plate 6013. The first slide plate 6014 has a first sliding groove 6015, which slides in cooperation with the first slide rail 604. The second slide plate 6012 is arranged on both sides of the second filter plate. The second slide plate 6012 has a second sliding groove 6018, which cooperates with the second slide rail 605. This ensures the normal operation of the upper filter plate 6013 and the lower filter plate 6017 and prevents the upper filter plate 6013 and the lower filter plate 6017 from shaking during operation.

[0064] The two ends of the connecting plate 6019 are fixedly installed in the middle of the upper filter plate 6013 and the lower filter plate 6017, respectively. A strip hole 6020 is opened in the middle of the connecting plate 6019, and the connecting post 609 is located in the strip hole 6020. A fixing plate 6010 and a fixing pipe 709 are also provided at the top of the air collecting pipe 7. The fixing plate 6010 is fixedly installed on the top wall of the air collecting pipe 7, and the fixing plate 6010 is slidably engaged with the upper filter plate 6013. A connecting hole 704 is opened at the center of the bottom of the air collecting pipe 7. The connecting hole 704 is connected to the connecting pipe 8. The fixing pipe 709 is fixedly installed in the connecting hole 704, and the fixing pipe 709 is slidably engaged with the lower filter plate 6017.

[0065] The rotation of the rotating rod 603 causes the connecting column 609 to move in the strip hole 6020, which in turn causes the connecting plate 6019 to move back and forth along the air collection pipe 7. The movement of the connecting plate 6019 causes the upper filter plate 6013, the lower filter plate 6017, and the inclined plate 6016 to move back and forth. During the movement of the upper filter plate 6013 and the lower filter plate 6017, the upper filter plate 6013 cooperates with the fixed plate 6010 to scrape off the dust on the top of the upper filter plate 6013, and under the action of the inclined plate 6016, the dust is transported to the collection box 10. During the movement of the lower filter plate 6017, it cooperates with the fixed pipe 709 to scrape off the dust on the bottom of the lower filter plate 6017, and the scraped dust is transported to the collection box 10. This not only prevents dust from clogging the filter holes on the upper filter plate 6013 and the lower filter plate 6017, but also ensures that the dust is collected and discharged in a concentrated manner, thus ensuring the efficiency and quality of dust treatment in the air.

[0066] In this embodiment, as Figure 15 , Figure 16 , Figure 17 As shown, the discharge component 4 includes a fifth pulley 407, a third belt 4014, a mounting shaft 406, a first gear 408, a second gear 4010, a connecting shaft 4011, a rotating arm 4012, a fixed shaft 4013, a connecting rod 409, a fixed rod 404, an upper sliding plate 403, a lower sliding plate 401, a pusher plate 405, and a discharge plate 402. The upper sliding plate 403 and the lower sliding plate 401 are arranged one above the other, and the upper sliding plate 403 slides in cooperation with the upper inner wall of the dust collection box 1, while the lower sliding plate 401 slides in cooperation with the lower inner wall of the dust collection box 1. The pusher plate 405 is symmetrically arranged at both ends of the lower sliding plate 401 and is fixedly installed on the lower sliding plate 401. The pusher plate 405 is used to push the dust inside the dust collection box 1 to the outside of the dust collection box 1, thereby ensuring that the dust collection box 1 can work continuously.

[0067] The feeding plate 402 is inclined and its two ends are fixedly installed at the ends of the upper slide plate 403 and the top of the pusher plate 405, respectively. The feeding plate 402 is used to transport the dust filtered out by the filter cylinder 901 in the connecting pipe 8 to the bottom plate inside the dust collection box 1, so that the pusher plate 405 can transport the dust in the dust collection box 1 to the outside of the dust collection box 1.

[0068] The two ends of the fixed rod 404 are respectively fixedly installed on the feed plate 402. The mounting shaft 406 is rotatably installed on the side wall of the dust collection box 1. The fifth pulley 407 is located on the outside of the dust collection box 1 and is fixedly installed on the mounting shaft 406. The fifth pulley 407 is connected to the second pulley 207 through the third belt 4014. The first gear 408 is fixedly installed on the mounting shaft 406. One end of the connecting rod 409 is fixedly installed on the mounting shaft 406. The connecting shaft 4011 is rotatably installed on the other end of the connecting rod 409. The second gear 4010 is fixedly installed on the connecting shaft 4011. The second gear 4010 is located on one side of the first gear 408 and meshes with the first gear 408. The fixed shaft 4013 is fixedly installed on the fixed rod 404. One end of the rotating arm 4012 is fixedly installed on the connecting shaft 4011, and the other end of the rotating arm 4012 is rotatably installed on the fixed shaft 4013.

[0069] The second pulley 207 drives the fifth pulley 407 to rotate via the third belt 4014. The rotation of the fifth pulley 407 drives the mounting shaft 406 to rotate. The rotation of the mounting shaft 406 drives the first gear 408 and the connecting rod 409 to rotate. The second gear 4010 then rotates along the first gear 408 and also rotates on its own axis. During the rotation of the second gear 4010, one end of the rotating arm 4012 rotates. While the other end of the rotating arm 4012 rotates around the fixed shaft 4013, it also pushes the upper slide plate 403, the lower slide plate 401, the pusher plate 405, and the unloading plate 402 to reciprocate within the dust collection box 1. During the reciprocating motion, the pusher plate 405 discharges dust.

[0070] In this embodiment, as Figure 14As shown, the sealing component 3 includes a sealing plate 301, a second spring 302, a guide rod 303, a baffle 304, a lifting plate 307, and a horizontal plate 306. The sealing plate 301 is slidably mounted on the dust collection box 1. A sliding rod 305 is provided on the top of the sealing plate 301. The guide rods 303 are symmetrically arranged on both sides of the center line of the sliding rod 305. The guide rods 303 and the sliding rod 305 are slidably engaged. The guide rods 303 are used to guide the sliding rod 305 to ensure the normal operation of the sliding rod 305. The guide rods 303 also facilitate the installation of the second spring 302 to ensure the normal operation of the second spring 302.

[0071] The baffle 304 is fixedly installed on the top of the guide rod 303. The baffle 304 is set to limit the stroke of the sealing plate 301 and ensure that the sealing plate 301 always cooperates with the guide rod 303.

[0072] The second spring 302 is sleeved on the guide rod 303, and the second spring 302 is located between the baffle 304 and the bend 509. The second spring 302 is used to continuously provide a downward force for the sliding rod 305, so as to ensure that the sealing plate 301 can always seal the dust collection box 1 and ensure the normal operation of the dust collection box 1.

[0073] A support plate 308 is also provided at the bottom of the sealing plate 301. The horizontal plate 306 is located above the support plate 308 and the support plate 308 is fixedly connected to the sealing plate 301. The lifting plate 307 is inclined and its two ends are connected to the horizontal plate 306 and the support plate 308 respectively. The lifting plate 307 cooperates with the feeding plate 402. The horizontal plate 306 and the support plate 308 are provided for the installation of the lifting plate 307 to ensure that the lifting plate 307 is always in a stable state during operation.

[0074] The feeding plate 402 and the lifting plate 307 work together to lift the sealing plate 301 upwards. Under the action of the pushing plate 405, the dust inside the dust collection box 1 is discharged from the bottom of the sealing plate 301 to the outside of the dust collection box 1. During the sliding of the upper slide plate 403, the upper slide plate 403 will seal the connection between the connecting pipe 8 and the dust collection box 1 to prevent air from entering the dust collection box 1 from the dust discharge end.

[0075] For example, when the lower plate 402 and the pusher plate 405 move to the left, the lower plate 402 will cooperate with the lifting plate 307 on the sealing member 3 on the left side of the dust collection box 1, thereby lifting the sealing plate 301 on the left side, and the filtered dust will be discharged from the left side of the dust collection box 1 under the action of the pusher plate 405.

[0076] As the feeding plate 402 and the pusher plate 405 move to the left, they will cause the upper slide plate 403 and the lower slide plate 401 to move to the left. The upper slide plate 403, in conjunction with the feeding plate 402 and the pusher plate 405 on the left, will disconnect the left end of the dust collection box 1 from the connecting pipe 8. That is, at this time, air cannot enter the connecting pipe 8 from the left end of the dust collection box 1, and the dust filtered out from the filter cartridge 901 in the connecting pipe 8 will fall onto the feeding plate 402 on the right side of the upper slide plate 403. The dust will fall along the feeding plate 402 on the right side of the upper slide plate 403 to the right side of the center line of the dust collection box 1. When the upper slide plate 403 and the lower slide plate 401 move to the right, the dust will be discharged from the right end of the dust collection box 1, ensuring that the dust can be discharged from the dust collection box 1 in a timely manner, thus improving the efficiency and quality of dust treatment.

[0077] In this embodiment, as Figure 4 , Figure 5 As shown, a telescopic pipe 11 is also provided at the top of the connecting pipe 8. The two ends of the telescopic pipe 11 are connected to the connecting pipe 8 and the gas collecting pipe 7, respectively. A first flange 12 is provided at both ends of the telescopic pipe 11. A sliding pipe 13 is provided on the first flange 12 at the top of the telescopic pipe 11. A second flange 15 is provided at both ends of the connecting pipe 8. A fixed column 16 is provided on the second flange 15 at the bottom of the connecting pipe 8. The sliding pipe 13 and the fixed column 16 are slidably engaged. With the cooperation of the sliding pipe 13 and the fixed column 16, the telescopic pipe 11 and the gas collecting pipe 7 can be kept in a stable state during operation, which improves the efficiency and quality of dust treatment of the device.

[0078] A cylinder 14 is provided on the flange at the bottom of the connecting pipe 8. The piston rod of the cylinder 14 passes through the second flange 15 at the top of the connecting pipe 8, the first flange 12 at the bottom of the telescopic pipe 11, and the first flange 12 at the top of the telescopic pipe 11. A clearance hole is provided on the second flange 15 at the upper end of the connecting pipe 8 and the first flange 12 at the lower end of the telescopic pipe 11. The sliding pipe 13 slides with the clearance hole.

[0079] The cylinder 14, in conjunction with the telescopic tube 11, can drive the air collecting pipe 7 to rise and fall, thereby achieving the purpose of raising and lowering the air collecting pipe 7 and improving the flexibility of the device.

[0080] The first flange 12 and the second flange 15 facilitate the installation of the fixed column 16 and the sliding tube 13, ensuring the normal operation of the fixed column 16 and the sliding tube 13.

[0081] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
