Description

Technical Field

[0001] The present invention relates to the technical field of dust removal in metal processing, and specifically, to a dust removal device for metal processing. Background Art

[0002] Metal processing refers to the production activities of humans to process materials with metal characteristics composed of metal elements or mainly composed of metal elements. This is a process technology that processes metal materials into articles, parts, and components, including large parts such as bridges and ships, and even the delicate components of engines, jewelry, and watches. Metal processing is widely used in different fields such as science, industry, art, and handicrafts.

[0003] Currently, during metal processing, processes such as cutting, grinding, drilling, and welding will generate a large amount of dust and particulate matter. These dusts not only affect the working environment and reduce air quality, but may also pose a threat to the health of operators, such as causing respiratory diseases. Therefore, during metal processing, the dust removal device required is very important. Due to the wide variety of dusts generated during metal processing, the commonly used dust removal device is usually a bag filter. Because the bag filter can adapt to different types and concentrations of dusts, including metal dusts and non-metal dusts, the bag filter can handle these different types of dusts and meet the dust removal requirements of the metal processing industry. Therefore, during metal processing, the bag filter is often widely used for dust removal work.

[0004] Currently, when using a bag filter, usually, the dust-containing gas is first sucked into the interior of the dust collector through the air inlet by a blower. Subsequently, due to the principle that the internal space of the dust collector is larger than the air inlet, the velocity of the gas entering the interior of the dust collector will relatively decrease. Then, the relatively heavier particulate dust in the air flow will fall into the ash hopper under the action of gravity, inertia, etc. for preliminary separation. Then, the larger particles are secondarily filtered through the filter plate. Finally, when the dust-containing gas passes through the cloth bag, the finer dust will be blocked on the outer surface of the cloth bag, while the purified gas will pass through the cloth bag and be discharged, thus completing the dust removal work. As the dust accumulates on the cloth bag continuously, to prevent the air flow from being blocked due to serious blockage of the cloth bag, it is necessary to clean the cloth bag. Then, the fallen dust will be discharged through the discharge port. However, since the dust particles after multiple filtrations are usually small in volume and light in weight, and the air flow at the ash hopper in the interior of the dust collector is relatively strong, the dust particles are easily affected by the air flow when entering the ash hopper, resulting in the suspension of the dust in the ash hopper and being not easy to settle, affecting the normal dust collection function of the ash hopper, and possibly causing the fallen dust to be re-entrained by the slight disturbance of the air flow and re-attach to the filter bag, thus significantly reducing the dust removal efficiency of the dust collector.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In this dust removal device for metal processing, by starting the driving motor, the connecting roller drives the auger blade to rotate. Then, as the auger blade continuously rotates inside the feeding bin, the dust particles falling inside the feeding bin are pushed and accumulated towards the baffle, causing the baffle to move. At the same time, the movement of the baffle causes the memory spring to deform under force. Through the movement of the baffle and the reaction force of the spring, the dust is subjected to a certain degree of extrusion and adhered into blocks. Since the mass and volume of the adhered dust blocks become larger and heavier, it prevents the dust particles from being easily affected by the airflow and settling when entering the ash hopper, or the fallen dust from being re-swept up due to the slight disturbance of the airflow.

[0018] 2. In this dust removal device for metal processing, as the connecting roller rotates, it also drives the engagement between the toothed ring and gear A, so that gear A drives drive wheel A to rotate. When drive wheel A rotates, it drives drive wheel B to rotate through the transmission belt. When drive wheel B rotates, it drives drive wheel C to rotate synchronously through the connecting rod. When drive wheel B and drive wheel C rotate synchronously, the clamping posts at the outer edge rotate around the axis of drive wheel B, and the limiting sliding between the L-shaped rack and the mounting seat causes the clamping posts to drive the L-shaped rack to move horizontally back and forth. When the L-shaped rack moves, through the engagement with gear B, the gear drives the rack to move horizontally back and forth synchronously. Then, the rack drives the brush to move along the filter plate synchronously, so as to clean the filter plate, keep the surface of the filter plate relatively unobstructed, and reduce the blockage of the filter plate during long-term use.

[0019] 3. In the dust removal device for metal processing, the baffle drives the hinge B to move synchronously through the connecting block, so that the adjustment plate A and the adjustment plate B are hinged with the connecting rod on the inner side of the connecting member. When the dust material accumulates, the movement of the baffle will increase the angle between the adjustment plate A and the adjustment plate B, so that the mounting frame approaches the feeding bin. When the mounting frame approaches the feeding bin, the reverse teeth of the ratchet wheel engage with the outer wall of the spring plate, so that the connecting column can rotate. When the connecting column rotates, it will synchronously drive the cleaning roller to rotate. Then, when the mounting frame approaches the feeding bin, the rotating cleaning roller can send the dust at the connection between the mounting seat and the feeding bin into the feeding bin, thereby suppressing the local dust accumulation inside the box and preventing the accumulated dust from affecting the structural device parts inside the box.

[0020] 4. In the dust removal device for metal processing, when the mounting frame approaches the outer side of the feeding bin, it will drive the hinge block 2 to be hinged with the hinge plate, so that the hinge plate drives the rack 2 to slide downward on the inner wall of the limiting path, and while the rack 2 is sliding down, it meshes with the gear C, so that the gear C rotates, and while the gear C rotates, it meshes with the rack 3, and then drives the rack 3 to slide upward on the inner side of the limiting path. When the rack 3 slides up, it will drive the cross plate upward synchronously through the L-shaped connecting plate, and when the mounting frame approaches the outer side of the mounting seat, the rack 2 will slide up, and the sliding rack 2 will mesh with the gear C, and then the gear C will drive the rack 3 to slide down quickly. At the same time, the rack 3 in the sliding process will synchronously drive the L-shaped connecting plate to slide down synchronously, so that the cross plate will beat the filter plate driven by the L-shaped connecting plate, so that the filter plate vibrates, causing the attachments to loosen and fall off, thereby further maintaining the smoothness of the filter plate.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the purpose of this embodiment is to provide a dust removal device for metal processing, which includes a support frame 1. Inside the support frame 1, a box body 2 is fixedly installed. At the bottom end of the box body 2, a ash hopper 3 is communicated. Inside the box body 2, a mounting seat 4 is arranged. On the outer side of the mounting seat 4, two filter plates 41 are symmetrically and fixedly installed. Inside the mounting seat 4, a feeding bin 5 is fixedly connected. On the inner wall of the feeding bin 5, a feeding port 51 is opened. On both sides of the feeding port 51, two sliding grooves 52 are symmetrically opened on the inner wall of the feeding bin 5.

On the inner wall of the mounting seat 4, two memory springs 58 are symmetrically and fixedly connected. The ends of the two memory springs 58 are fixedly connected to one side of the baffle 54. On the inner wall of the baffle 54, two limiting columns 59 are symmetrically and slidably connected. One end of each of the two limiting columns 59 is fixedly connected to the inner wall of the mounting seat 4. The other ends of the two limiting columns 59 are fixedly connected with clamping blocks 510, and the outer walls of the two clamping blocks 510 are fixedly connected to the inner side of the feeding bin 5. On both sides of the feeding bin 5, feeding ports 511 are opened. Above the feeding ports 511, limiting grooves 512 are opened on the inner wall of the feeding bin 5; A sliding track 521 is opened on the inner wall of one of the sliding grooves 52, and the feeding bin 5 limits the limiting slider 53 through the sliding track 521. On the inner wall of the other sliding groove 52, a plurality of support springs 522 are fixedly connected. Between the ends of the plurality of support springs 522, a push plate 523 is fixedly connected.

[0038] A support base 7 is fixedly connected to the outer wall of the box body 2. A driving motor 71 is fixedly installed inside the support base 7. The output shaft of the driving motor 71 penetrates through the inside of the box body 2 and is fixedly connected to the end of the connecting roller 56. A toothed ring 72 is fixedly connected to the outside of the connecting roller 56. The outer edge of the toothed ring 72 meshes with a gear A73. One side of the gear A73 is rotatably connected to the inner wall of the box body 2. The other side of the gear A73 is fixedly connected to a transmission wheel A74. A transmission belt 75 is arranged outside the transmission wheel A74. Transmission wheels B76 are arranged outside the feeding bin 5 on both sides of the transmission wheel A74. And the two transmission wheels B76 are in transmission connection with the outside of the transmission wheel A74 through the transmission belt 75. Connecting rods 77 are fixedly connected to the outer walls of the two transmission wheels B76. Support plates 78 are rotatably connected to the outer walls of the two connecting rods 77. And the outer walls of the two support plates 78 are fixedly connected to the outer wall of the mounting seat 4. Transmission wheels C79 are fixedly connected to the ends of the two connecting rods 77. Clamping posts 710 are fixedly connected to the outer edges of one side of the transmission wheel C79 and the transmission wheel B76. L-shaped racks 711 are slidably connected to the outer walls of the clamping posts 710. And the outer walls of the L-shaped racks 711 are slidably connected to the inner wall of the mounting seat 4. The teeth of the L-shaped racks 711 are all meshed with gears B712. And one side of each gear B712 is rotatably connected to the inner wall of the mounting seat 4. The outer edge of the gear B712 meshes with a rack one 713. Connecting rings 714 are fixedly connected to the lower surfaces of the rack one 713. And a brush 715 is rotatably connected between the inner walls of every two connecting rings 714; Limit seats 8 are slidably connected to the outer walls of the rack one 713. The outer walls of the limit seats 8 are fixedly connected to the outer wall of the mounting seat 4.

[0039] In this implementation scheme, first, when the dust and impurities on the surface of the cloth bag 102 are removed, they will fall on the mounting base 4 and the feeding bin 5. Subsequently, by starting the driving motor 71, the connecting roller 56 will drive the auger blade 57 to rotate. Then, as the auger blade 57 continuously rotates inside the feeding bin 5, the dust particles that have fallen inside the feeding bin 5 will be pushed towards the baffle 54. As the dust particles at the baffle 54 continuously accumulate, they will push the baffle 54 towards the inside of the mounting base 4. When the baffle 54 moves, through the limitation of the two limit posts 59, to ensure the stability of the baffle 54 during movement, the memory spring 58 will be deformed by the force. Then, through the reaction force of the memory spring 58, and as the dust material accumulates, when the baffle 54 is pushed to move, the dust will be adhesively formed into blocks under a certain extrusion force by the pushing of the auger blade 57 and the reaction force of the spring. Then, when the baffle 54 moves, the limit slider 53 will also move from the initial position in the chute 52 to another chute 52, so that the discharge port 51 can be exposed. When the discharge port 51 is exposed, the adhesively formed dust material will fall from the discharge port 51 and then fall into the ash hopper 3. And because the mass and volume of the adhesively formed dust become larger and heavier, it can prevent the dust particles from being easily affected by the airflow and settling when entering the ash hopper 3, or being re-suspended due to the slight disturbance of the airflow of the falling dust.

[0040] Secondly, when the driving motor 71 is started and then the connecting roller 56 rotates, as the connecting roller 56 rotates, it will also drive the gear ring 72 to rotate accordingly. When the gear ring 72 rotates, through the meshing with the gear A73, the gear A73 will drive the transmission wheel A74 to rotate synchronously. When the transmission wheel A74 rotates, it will drive the transmission wheel B76 to rotate through the transmission belt 75. When the transmission wheel B76 rotates, it will drive the transmission wheel C79 to rotate synchronously through the connecting rod 77. When the transmission wheel B76 and the transmission wheel C79 rotate synchronously, the clamping post 710 at the outer edge will rotate around the axis of the transmission wheel B76. During the rotation of the clamping post 710, through the limiting sliding with the L-shaped rack 711 and the limiting sliding between the L-shaped rack 711 and the mounting base 4, the L-shaped rack 711 will perform a horizontal reciprocating movement. When the L-shaped rack 711 moves, through the meshing with the gear B712, the gear will drive the rack one 713 to perform a horizontal reciprocating movement synchronously. When the rack one 713 moves, it will drive the brush 715 to move along the filter plate 41 synchronously, so as to clean the filter plate 41, keep the surface of the filter plate 41 relatively unobstructed, and reduce the situation of blockage of the filter plate 41 during long-term use.

[0041] In this embodiment, Figure 10 、 Figure 11 andFigure 12 As shown in the figure, two pairs of connecting seats 6 are fixedly connected to the outside of the feeding bin 5, and a plurality of spring plates 61 are fixedly connected to the outside of the connecting seats 6. A connecting column 62 is arranged between every two connecting seats 6. Limiting blocks 63 are fixedly connected to both ends of the connecting column 62. The outer wall of the limiting block 63 is slidably connected to the inner wall of the connecting seat 6. A ratchet wheel 64 is fixedly connected to one side of the limiting block 63. The teeth of the ratchet wheel 64 are engaged with the outer wall of the spring plate 61. A cleaning roller 65 is fixedly connected to the outer wall of the connecting column 62. An installation frame 66 is arranged between the two sides of the cleaning roller 65. The inner wall of the installation frame 66 is rotatably connected to the outer wall of the connecting column 62. A connecting piece 67 is slidably connected to one side of the installation frame 66. A connecting rod 68 is fixedly connected to the inner wall of the connecting piece 67. An adjusting plate A69 and an adjusting plate B610 are respectively hinged to the outer wall of the connecting rod 68. One end of the adjusting plate A69 is hinged to a hinge piece A611. The outer wall of the hinge piece A611 is fixedly connected to the outer wall of the feeding bin 5. One end of the adjusting plate B610 is hinged to a hinge piece B612. A connecting block 613 is fixedly connected to the outer wall of the hinge piece B612. The outer wall of the connecting block 613 is slidably connected to the inner wall of the limiting groove 512. One side of the connecting block 613 is fixedly connected to the outer wall of the baffle 54.

[0042] In this implementation scheme, when the baffle 54 is in the initial position, the cleaning roller 65 is located near the inner side of the mounting seat 4. Under the accumulation of dust materials, when the baffle 54 is pushed to move, the baffle 54 will synchronously drive the hinge piece B612 to move through the connecting block 613. During the movement of the connecting block 613, due to the limitation of the limiting groove 512, the movement of the connecting block 613 is stable. When the hinge piece B612 moves, it will cause the adjusting plate A69 and the adjusting plate B610 to be hinged inside the connecting piece 67 with the connecting rod 68. Under the accumulation of dust materials, when the baffle 54 is promoted to move, the angle between the adjusting plate A69 and the adjusting plate B610 will become larger, so that the connecting piece 67 can drive the installation frame 66 to approach the outside of the feeding bin 5. When the installation frame 66 approaches the outside of the feeding bin 5, the reverse teeth of the ratchet wheel 64 will be engaged with the outer wall of the spring plate 61, so that the connecting column 62 can rotate. When the connecting column 62 rotates, it will synchronously drive the cleaning roller 65 to rotate. Then, when the installation frame 66 approaches the outside of the feeding bin 5, the rotating cleaning roller 65 can scrape and clean the position where it is located. When approaching the feeding port 511, the rotating cleaning roller 65 can send the dust at the connection between the mounting seat 4 and the feeding bin 5 into the inside of the feeding bin 5 through the feeding port 511, so as to inhibit the occurrence of local dust accumulation inside the box body 2 and prevent the accumulated dust from affecting the structural device parts inside the box body 2.

[0043] In this embodiment, as Figure 13As shown, two pairs of limiting paths 9 are symmetrically provided on the inner wall of the mounting seat 4, and the inner walls of the limiting paths 9 are rotatably connected with gears C91, and the outer edges of the gears C91 are respectively meshed with racks 2 92 and racks 3 93, and the outer walls of racks 2 92 and racks 3 93 are slidably connected to the inner wall of the limiting path 9, and one side of the rack 2 92 is fixedly connected with a hinge block 1 94, and the inner wall of the hinge block 1 94 is hinged with a hinge plate 95, and one end of the hinge plate 95 is hinged with a hinge block 2 96, and the lower surface of the hinge block 2 96 is fixedly connected to the upper surface of the mounting frame 66, and one side of the rack 3 93 is fixedly connected with an L-shaped connecting plate 97, and the lower surface of the L-shaped connecting plate 97 is fixedly connected with a cross plate 98.

[0044] In this embodiment, when the mounting frame 66 approaches the outside of the feeding bin 5, it drives the hinge block 2 96 to be hinged with the hinge plate 95, so that the hinge plate 95 drives the rack 2 92 to slide downward on the inner wall of the limiting path 9, and while the rack 2 92 slides down, it meshes with the gear C91, so that the gear C91 rotates, and while the gear C91 rotates, it meshes with the rack 3 93, and then drives the rack 3 93 to slide upward on the inner side of the limiting path 9, and while the rack 3 93 slides up, it drives the cross plate 98 through the L-shaped connecting plate 97. When the mounting frame 66 moves upward synchronously and approaches the outer side of the mounting seat 4, the rack 2 92 will slide up, and the sliding rack 2 92 will mesh with the gear C91, and then the gear C91 will drive the rack 3 93 to slide down quickly. At the same time, the rack 3 93 in the sliding process will synchronously drive the L-shaped connecting plate 97 to slide down synchronously, so that the cross plate 98 will beat the filter plate 41 under the drive of the L-shaped connecting plate 97, so that the filter plate 41 will vibrate, causing the attachments to loosen and fall off, thereby further maintaining the smoothness of the filter plate 41.

[0045] In this embodiment, Figure 2 and Figure 3 As shown, a fixing frame A11 is provided outside the box body 2, and a fan 111 is fixedly installed on the upper surface of the fixing frame A11, and an input end of the fan 111 is fixedly connected to an exhaust pipe 112, one end of the exhaust pipe 112 is connected to the inside of the box body 2, and an output end of the fan 111 is fixedly connected to an exhaust pipe 113; a porous plate 10 is fixedly connected to the inner wall of the box body 2 above the mounting seat 4, and support frames 101 are provided at the holes of the porous plate 10, and cloth bags 102 are provided on the outside of the support frames 101; the interior of the ash hopper 3 is connected to an air inlet pipe 13, and the bottom end of the ash hopper 3 is connected to a one-way valve 14;

[0046] On one side of the box body 2, a fixed frame B12 is fixedly connected. An air pump 121 is arranged on the upper surface of the fixed frame B12. The output end of the air pump 121 is communicated with a grading pipe 122. The output end of the grading pipe 122 is provided with a plurality of pulse valves 123. The output ends of the pulse valves 123 are all communicated with air injection pipes 124. A plurality of nozzles 125 are communicated inside the air injection pipes 124, and the output ends of the plurality of nozzles 125 correspond to the openings of the plurality of support frames 101.

[0047] In this embodiment, when the fan 111 starts, it sucks air into the box body 2 through the air extraction pipe 112, so as to generate an air flow on the inner wall of the box body 2. Then the generated air flow extracts the dust-containing air outside the box body 2 through the air inlet pipe 13. After the dust-containing air passes through the filtration of the filter plate 41 and the cloth bag 102, under the influence of the air flow generated by the fan 111, it enters the air extraction pipe 112 and then is discharged through the exhaust pipe 113, thus completing the function of air dust removal and filtration. By starting the air pump 121 to inject air flow into the grading pipe 122, then the air flow enters a plurality of air injection pipes 124 through the grading pipe 122. During the process of the air flow passing through the air injection pipes 124, it will be compressed by the pulse valves 123 to enhance the air pressure. Then the compressed air flow will be sprayed into the interior of the support frame 101 through a plurality of nozzles 125, so as to remove dust and other impurities on the cloth bag 102, thereby maintaining the normal operation and efficient filtration of the dust collector.

[0048] In summary, the working principle of the present invention is as follows:

[0049] First, by starting the fan 111, when the fan 111 starts, it sucks air into the interior of the box body 2 through the suction pipe 112, thereby generating an air flow on the inner wall of the box body 2. Then, the generated air flow extracts the dust-containing air outside the box body 2 through the air inlet pipe 13. After the dust-containing air passes through the filtration of the filter plate 41 and the cloth bag 102, under the influence of the air flow generated by the fan 111, it enters the suction pipe 112 and then is discharged through the exhaust pipe 113, thus completing the function of air dust removal and filtration. By starting the air pump 121, air flow is injected into the grading pipe 122. Subsequently, the air flow enters multiple jet pipes 124 through the grading pipe 122. During the process of the air flow passing through the jet pipes 124, it is compressed by the pulse valve 123 to enhance the air pressure. Then, the compressed air flow is sprayed through multiple nozzles 125 towards the inside of the support frame 101 to remove dust and other impurities on the cloth bag 102. After the dust blows off the surface of the cloth bag 102, it will fall on the mounting seat 4 and the feeding bin 5. Subsequently, by starting the driving motor 71, the connecting roller 56 drives the auger blade 57 to rotate. Then, as the auger blade 57 continuously rotates inside the feeding bin 5, the dust particles falling inside the feeding bin 5 are pushed towards the baffle 54. As the dust particles at the baffle 54 continuously accumulate, they will push the baffle 54 towards the inside of the mounting seat 4. When the baffle 54 moves, through the limitation of the two limiting posts 59, to ensure the stability of the baffle 54 during movement, the memory spring 58 will be deformed under force. Then, through the reaction force of the memory spring 58, and as the dust material accumulates, when the baffle 54 is pushed to move, the dust will be squeezed and bonded into blocks under the push of the auger blade 57 and the reaction force of the spring. Then, when the baffle 54 moves, it will also cause the limit slider 53 to move from the initial position in the chute 52 to another chute 52, thereby exposing the feeding port 51. When the feeding port 51 is exposed, the bonded dust material will fall from the feeding port 51 and then into the ash hopper 3. At the same time when the feeding port 51 is exposed, due to the elastic force of the support spring 522 itself, the push plate 523 will be pushed to move to the opening of one of the chutes 52 to prevent dust from entering the chute 52. And because the mass and volume of the bonded dust become larger and heavier, it can prevent the dust particles from being easily affected by the air flow and settling when entering the ash hopper 3, or being re-suspended due to the slight disturbance of the air flow. Then, when the dust inside the feeding bin 5 is processed, according to the elastic force of the memory spring 58 itself, the baffle 54 will be quickly pushed back to the initial position. Secondly, when the driving motor 71 is started and the connecting roller 56 rotates, as the connecting roller 56 rotates, it will also drive the gear ring 72 to rotate accordingly. When the gear ring 72 rotates, through the meshing with the gear A73, the gear A73 will drive the transmission wheel A74 to rotate synchronously. When the transmission wheel A74 rotates,It will drive the driving wheel B76 to rotate through the conveyor belt 75. When the driving wheel B76 rotates, it will drive the driving wheel C79 to rotate synchronously through the connecting rod 77. When the driving wheel B76 and the driving wheel C79 rotate synchronously, the clamping column 710 at the outer edge will rotate around the axis of the driving wheel B76. During the rotation of the clamping column 710, through the limit sliding between the L-shaped rack 711 and the limit sliding between the L-shaped rack 711 and the mounting seat 4, the L-shaped rack 711 will perform a horizontal reciprocating movement. When the L-shaped rack 711 moves, it will drive the gear B712 to drive the rack one 713 to perform a horizontal reciprocating movement synchronously through meshing. When the rack one 713 moves, it will drive the brush 715 to move along the filter plate 41 synchronously, so as to clean the filter plate 41, keep the surface of the filter plate 41 relatively unobstructed, reduce the blockage of the filter plate 41 during long-term use, and since the baffle 54 is located at the initial position, the cleaning roller 65 is located near the inner side of the mounting seat 4. Under the accumulation of dust materials, when the baffle 54 is pushed to move, the baffle 54 will synchronously drive the hinge B612 to move through the connecting block 613. During the movement of the connecting block 613, through the limit of the limit groove 512, the stability of the connecting block 613 during movement is ensured. When the hinge B612 moves, it will cause the adjusting plate A69 and the adjusting plate B610 to be hinged with the connecting rod 68 inside the connecting member 67. Under the accumulation of dust materials, when the baffle 54 is prompted to move, the angle between the adjusting plate A69 and the adjusting plate B610 will become larger, so that the connecting member 67 can drive the mounting bracket 66 to approach the outside of the feeding bin 5. When the mounting bracket 66 approaches the outside of the feeding bin 5, the reverse teeth of the ratchet 64 will be engaged with the outer wall of the spring plate 61, so that the connecting column 62 can rotate. When the connecting column 62 rotates, it will synchronously drive the cleaning roller 65 to rotate. Then, when the mounting bracket 66 approaches the outside of the feeding bin 5, the rotating cleaning roller 65 can scrape and clean its own position. When approaching the feeding port 511, the rotating cleaning roller 65 can send the dust at the connection between the mounting seat 4 and the feeding bin 5 into the inside of the feeding bin 5 through the feeding port 511, so as to inhibit the local dust accumulation inside the box body 2 and prevent the accumulated dust from affecting the structural device parts inside the box body 2. When the mounting bracket 66 approaches the outside of the feeding bin 5, it will drive the hinge block two 96 to be hinged with the hinge plate 95, so that the hinge plate 95 drives the rack two 92 to slide downward along the inner wall of the limit track 9. When the rack two 92 slides downward, through meshing with the gear C91, the gear C91 rotates. When the gear C91 rotates, it meshes with the rack three 93, and then drives the rack three 93 to slide upward inside the limit track 9. When the rack three 93 slides upward,Then, it will drive the cross plate 98 to move upward synchronously through the L-shaped connecting plate 97. When the outer side of the mounting frame 66 approaches the mounting seat 4, the second rack 92 will slide upward. The upward-sliding second rack 92 meshes with the gear C91, and then the gear C91 drives the third rack 93 to slide downward rapidly. At the same time, the third rack 93 during the downward sliding process will drive the L-shaped connecting plate 97 to slide downward synchronously, so that the cross plate 98 beats the filter plate 41 under the drive of the L-shaped connecting plate 97, thereby causing the filter plate 41 to vibrate, promoting the loosening and falling of the attached substances, and further maintaining the smoothness of the filter plate 41.
