Description

Technical Field

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

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

[0003] At present, in the process of metal processing, such as cutting, grinding, drilling, welding and other processes, a large amount of dust and particulate matter will be generated. These dusts not only affect the working environment and reduce the air quality, but may also pose a threat to the health of operators, such as causing respiratory diseases. Therefore, in the metal processing process, the dust removal device needed is very important. Due to the wide variety of dust generated in the metal processing process, the more widely used dust removal device usually adopts bag dust collector, because bag dust collector can adapt to different types and concentrations of dust, including metal dust, non-metallic dust, etc. Bag dust collector can handle these different types of dust to meet the dust removal needs of the metal processing industry. Therefore, in the metal processing process, bag dust collector is often widely used in dust removal work in the metal processing process.

[0004] At present, when using bag dust collector, the fan is usually used to suck the dust-containing gas into the dust collector through the air inlet. Then, the principle that the internal space of the dust collector is larger than the air inlet is used, so that the dust entering the dust collector will be relatively weakened. Then, the heavier particles in the air flow fall into the ash hopper under the action of gravity and inertia for preliminary separation. Then, the larger particles are filtered for the second time through the filter plate. Finally, when the dust-containing gas passes through the bag, the finer dust will be blocked on the outer surface of the bag, and the purified gas will be discharged through the bag to complete the dust removal work. As the dust continues to accumulate on the bag In order to prevent the airflow from being blocked due to serious bag blockage, the bag needs to be cleaned, and the fallen dust will be discharged through the discharge port. However, the dust particles after multiple filtration are usually small in size and light in weight, and the airflow through the ash hopper inside the dust collector is strong, which makes the dust particles easily affected by the airflow when entering the ash hopper, causing the dust in the ash hopper to be suspended and not easy to settle, affecting the normal dust collection function of the ash hopper, and the fallen dust may be lifted up again due to slight disturbance of the airflow, and attached to the filter bag again under the drive of the airflow at the ash hopper, thereby significantly reducing the dust removal efficiency of the dust collector.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the dust removal device for metal processing, the driving motor is started, and then 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 toward the baffle, so that the baffle moves. At the same time, the movement of the baffle causes the memory spring to be deformed under force. Through the movement of the baffle and the reaction force of the spring, the dust is squeezed to a certain extent and bonded into blocks. Since the dust is bonded into blocks, its mass and volume will become larger and heavier, thereby preventing the dust particles from being easily affected by the airflow and easily settled when entering the ash hopper, or the fallen dust from being lifted up again due to the slight disturbance of the airflow.

[0017] 2. In the dust removal device for metal processing, as the connecting roller rotates, the gear ring and gear A are also driven to mesh, so that gear A drives transmission wheel A to rotate. When transmission wheel A rotates, transmission wheel B is driven to rotate through the transmission belt. When transmission wheel B rotates, transmission wheel C is driven to rotate synchronously through the connecting rod. When transmission wheels B and transmission wheels C rotate synchronously, the clamping column at the outer edge rotates about the axis of transmission wheel B, and the L-shaped rack and the mounting seat slide in a limited position, so that the clamping column drives the L-shaped rack to move back and forth laterally. When the L-shaped rack moves, the engagement with gear B causes the gear to drive rack 1 to move back and forth laterally synchronously, and then rack 1 drives the brush to move synchronously along the filter plate, thereby cleaning the filter plate, keeping the surface of the filter plate relatively unobstructed, and reducing the clogging of the filter plate after long-term use.

[0018] 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.

[0019] 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.

[0025] In the present embodiment, first, after the dust on the surface of the bag 102 is cleared off, it will fall on the mounting seat 4 and the feeding bin 5, and then the driving motor 71 will be started, thereby causing the connecting roller 56 to drive the auger blade 57 to rotate, and then as the auger blade 57 continues to rotate inside the feeding bin 5, the dust particles falling on the inside of the feeding bin 5 will be pushed toward the baffle 54, and as the dust particles on the baffle 54 continue to accumulate, the baffle 54 will be pushed toward the inside of the mounting seat 4, and when the baffle 54 moves, it is limited by two limit columns 59 to ensure the stability of the baffle 54 when moving, which will cause the memory spring 58 to be deformed under the force, and then the memory spring 58 The reaction force, and as the dust material accumulates, the baffle plate 54 is pushed to move, and the dust is squeezed and bonded into blocks under the push of the auger blade 57 and the reaction force of the spring.

[0030] 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.

[0031] 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; A fixing frame B12 is fixedly connected to one side of the box body 2, and an air pump 121 is arranged on the upper surface of the fixing frame B12. The output end of the air pump 121 is connected to a grading pipe 122, and a plurality of pulse valves 123 are arranged at the output end of the grading pipe 122. The output ends of the pulse valves 123 are all connected to jet pipes 124, and the interior of the jet pipe 124 is connected to a plurality of nozzles 125, and the output ends of the plurality of nozzles 125 correspond to the openings of the plurality of support frames 101.

[0032] In the present embodiment, when the fan 111 is started, air is sucked toward the interior of the box body 2 through the exhaust pipe 112, so that airflow is generated on the inner wall of the box body 2, and then the generated airflow draws dust-containing air toward the outside of the box body 2 through the air inlet pipe 13. After the dust-containing air is filtered by the filter plate 41 and the cloth bag 102, it enters the exhaust pipe 112 under the influence of the airflow generated by the fan 111, and then is discharged through the exhaust pipe 113, thereby completing the function of air dust removal and filtration. The air pump 121 is started to inject air into the classification pipe 122, and then the air flow passes through the classification pipe 122 and enters multiple injection pipes 124. In the process of the air flow passing through the injection pipe 124, it will be compressed by the pulse valve 123 to enhance the air pressure, and then the compressed air flow will be sprayed toward the inside of the support frame 101 through multiple 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.

[0033] In summary, the working principle of the present invention is as follows: First, by starting the fan 111, when the fan 111 is started, air is sucked toward the inside of the box 2 through the exhaust pipe 112, so that airflow is generated on the inner wall of the box 2, and then the generated airflow draws dust-containing air toward the outside of the box 2 through the air inlet pipe 13. After being filtered by the filter plate 41 and the bag 102, the dust-containing air enters the exhaust pipe 112 under the influence of the airflow generated by the fan 111, and then is discharged through the exhaust pipe 113, thereby completing the air dust removal and filtration. The air pump 121 is started to inject air into the classification pipe 122, and then the airflow passes through the classification pipe 122 into multiple injection pipes 124. In the process of the airflow passing through the injection pipe 124, it will be compressed by the pulse valve 123 to enhance the air pressure. , and then the compressed airflow will be sprayed toward the inside of the support frame 101 through multiple nozzles 125 to remove dust and other impurities on the bag 102. After the dust is blown off the surface of the bag 102, it will fall on the mounting seat 4 and the feeding bin 5. Then, by starting the drive motor 71, the connecting roller 56 drives the auger blade 57 to rotate. Then, as the auger blade 57 continues to rotate inside the feeding bin 5, the dust particles falling on the inside of the feeding bin 5 will be pushed toward the baffle 54. As the dust particles at the baffle 54 continue to accumulate, the baffle 54 will be pushed toward the inside of the mounting seat 4. When the baffle 54 moves, it is limited by two limit columns 59 to ensure that the baffle 54 moves. The stability will cause the memory spring 58 to be deformed by the force, and then through the reaction force of the memory spring 58, and as the dust material accumulates, the baffle plate 54 is pushed to move, and the dust will be squeezed and bonded into blocks under the push of the auger blade 57 and the reaction force of the spring, and then when the baffle plate 54 moves, it will also cause the limit slider 53 to move from the chute 52 in the initial position to another chute 52, so that the discharge port 51 can be exposed. When the discharge port 51 is exposed, the bonded dust material will fall from the discharge port 51 and then fall into the ash hopper 3. At the same time as the discharge port 51 is exposed, the elastic force of the support spring 522 itself will push the push plate 523 to move to the opening of one of the chute 52. , which is used to prevent dust from entering the chute 52, and because the mass volume of the dust blocks will become larger and heavier, it is prevented that the dust particles are easily affected by the airflow and easily settled when entering the ash hopper 3, or the dust that has fallen is likely to be lifted up again due to a slight disturbance of the airflow. Then, after the dust inside the feeding bin 5 is processed, the baffle 54 will be pushed to quickly return to its initial position according to the elastic force of the memory spring 58 itself. Secondly, when the driving motor 71 is started, the connecting roller 56 is rotated, and the rotation of the connecting roller 56 will also drive the gear ring 72 to rotate accordingly. When the gear ring 72 rotates, it meshes with the gear A73, so that the gear A73 drives the transmission wheel A74 to rotate synchronously, and when the transmission wheel A74 rotates,It will pass through the transmission belt 75, and then drive the transmission wheel B76 to rotate. When the transmission wheel B76 rotates, it will drive the transmission wheel C79 to rotate synchronously through the connecting rod 77. When the transmission wheels B76 and C79 rotate synchronously, the clamping column 710 at the outer edge will rotate about the axis of the transmission wheel B76. During the rotation of the clamping column 710, the limited sliding between the L-shaped rack 711 and the limited sliding between the L-shaped rack 711 and the mounting seat 4 will cause the L-shaped rack 711 to move back and forth laterally. When the L-shaped rack 711 moves, the meshing with the gear B712 will cause the gear to drive the rack 1 713 to move back and forth laterally synchronously. When the rack 1 713 moves It will drive the brush 715 to move synchronously along the filter plate 41, so as to clean the filter plate 41, keep the surface of the filter plate 41 relatively unobstructed, and reduce the clogging of the filter plate 41 after long-term use. In addition, when the baffle 54 is in the initial position, the cleaning roller 65 is located near the inner side of the mounting seat 4. When the dust material accumulates and 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, the connecting block 613 is limited by the limiting groove 512, so that the connecting block 613 is stable when moving. When the hinge B612 moves, the adjusting plate A69 and the adjusting plate B610 are connected to the connecting rod 68. The inner side of the connecting piece 67 is hinged, and under the accumulation of dust materials, the movement of the baffle plate 54 will increase the angle between the adjustment plate A69 and the adjustment plate B610, so that the connecting piece 67 can drive the mounting frame 66 to approach the outside of the feeding bin 5, and when the mounting frame 66 approaches the outside of the feeding bin 5, the reverse teeth of the ratchet 64 will engage with the outer wall of the spring plate 61, so that the connecting column 62 can rotate, and when the connecting column 62 rotates, it will synchronously drive the cleaning roller 65 to rotate, and then when the mounting frame 66 approaches the outside of the feeding bin 5, the rotating cleaning roller 65 can scrape and clean its own position, and when it approaches the feeding port 511, the rotating cleaning roller 65 can The dust at the connection between the mounting base 4 and the feeding bin 5 can be fed into the inner side of the feeding bin 5 through the feeding port 511, thereby suppressing the local dust accumulation inside the box body 2 and preventing the accumulated dust from affecting the structural device parts inside the box body 2. When the mounting bracket 66 approaches the outer side of the feeding bin 5, it will drive 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, thereby driving the rack 3 93 to slide upward on the inner side of the limiting path 9, and while the rack 3 93 slides up,The L-shaped connecting plate 97 will drive the horizontal plate 98 upward synchronously, and when the mounting frame 66 is close to the outer side of the mounting seat 4, the rack 2 92 will slide upward, 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 will synchronously drive the L-shaped connecting plate 97 to slide down synchronously, so that the horizontal 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 attached objects to loosen and fall off, thereby further maintaining the smoothness of the filter plate 41.
