Description

Technical Field

[0001] This invention relates to the field of dust collector technology, and in particular to a filter bag cleaning device and a bag filter for air pollution. Background Technology

[0002] In the field of air pollution control, baghouse dust collectors are widely used and highly efficient environmental protection equipment. Their core working component is the filter bag, which traps pollutants such as dust and particulate matter in the atmosphere through filtration, thereby purifying the gas. The filtration effect of the filter bag directly determines the dust removal efficiency of the baghouse dust collector. Over time, a large amount of dust gradually accumulates on the surface of the filter bag, forming a dust layer. If this dust is not cleaned in time, the filter bag's permeability will decrease and its resistance will increase, not only reducing dust removal efficiency but also shortening the filter bag's lifespan, increasing equipment operating costs and maintenance workload. Therefore, filter bag cleaning is a crucial step for the stable and efficient operation of baghouse dust collectors. A proper cleaning device can promptly remove dust from the surface of the filter bag, restore its filtration performance, ensure the long-term stable operation of the baghouse dust collector, and meet the environmental protection requirements for air pollution control.

[0003] In existing technologies, filter bag cleaning is mostly done manually. First, manual cleaning requires workers to disassemble each filter bag one by one and manually rub them to remove surface dust. This is cumbersome, labor-intensive, and has extremely low cleaning efficiency, failing to meet the needs of large-scale, continuous dust removal operations. Especially for a large number of filter bags, manual cleaning consumes a lot of manpower and time, significantly increasing labor costs. Second, the force and angle of manual cleaning are difficult to control, easily leading to incomplete and uneven cleaning, which will affect the operating efficiency of the dust collector in the long run. Furthermore, some methods use hammering devices for cleaning, which have complex structures, require multiple power sources to drive different components, are inconvenient to operate, have high maintenance costs, and suffer from poor power source synchronization, easily leading to component jamming and poor cleaning effect. Therefore, this invention proposes a filter bag cleaning device and baghouse dust collector for atmospheric pollution to solve the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a filter bag cleaning device and a baghouse dust collector for air pollution. This device utilizes a conical component to synchronously drive a first, second, third, and fourth moving block. The first and second moving blocks move in opposite directions, while the first and third moving blocks move in the same direction. The fourth moving block moves in opposite directions to the third moving block, and in the same direction as the second moving block. This movement pattern drives the first and second connecting rods to move synchronously in opposite directions, causing four points on the filter bag to extend outwards synchronously, while the other four points contract inwards synchronously, and vice versa. Through this alternating extension and retraction motion, the filter bag is thoroughly washed in all directions, quickly and completely removing dust adhering to its surface.

[0005] To achieve the objectives of this invention, the invention is implemented through the following technical solution: a filter bag cleaning device for air pollution, comprising a base and a cone, wherein the base includes a first base and a second base located above, and a third base and a fourth base located below. A first moving block, a second moving block, a third moving block, and a fourth moving block are respectively movably provided at the four corners of the first base, the second base, the third base, and the fourth base. The first moving block and the second moving block are offset, and the first moving block and the third moving block correspond to each other and are connected by a first connecting rod. The fourth moving block and the third moving block are offset, and the fourth moving block corresponds to the second moving block and are connected by a second connecting rod. A filter bag is sleeved on the outer side of the first connecting rod and the second connecting rod.

[0006] The conical component is used to synchronously drive the first moving block, the second moving block, the third moving block and the fourth moving block to move. The first moving block moves in the opposite direction to the second moving block and moves in the same direction to the third moving block. The fourth moving block moves in the opposite direction to the third moving block and moves in the same direction to the second moving block.

[0007] A further improvement is that the conical component includes a first cone, a second cone, a third cone, and a fourth cone. The first cone, the second cone, the third cone, and the fourth cone are respectively movably disposed inside the first seat, the second seat, the third seat, and the fourth seat and move synchronously. The first cone, the second cone, the third cone, and the fourth cone respectively drive the first moving block, the second moving block, the third moving block, and the fourth moving block to move.

[0008] A further improvement is that the inclined surfaces of the first and second cones are opposite each other, the inclined surfaces of the third and fourth cones are opposite each other, the inclined surfaces of the first and second seats are opposite each other, and the inclined surfaces of the third and fourth seats are opposite each other.

[0009] A further improvement is that a cylinder is connected above the first cone, and the cylinder is used to drive the first cone, the second cone, the third cone and the fourth cone to move synchronously.

[0010] The further improvement is that the first, second, third, and fourth seats have the same structure, and each of the first, second, third, and fourth seats includes an inner cone and an edge. The edge is provided on the inner cone, and the inner cone has an inner cavity adapted to the cone component. The edge has a T-slot adapted to the first, second, third, and fourth moving blocks.

[0011] A further improvement is that the first moving block, the second moving block, the third moving block, and the fourth moving block have the same structure, and each of the first moving block, the second moving block, the third moving block, and the fourth moving block includes a T-shaped block and an inclined slider. The T-shaped block is movably adapted to the T-shaped groove, and the inclined slider is located at the inner end of the T-shaped block.

[0012] A further improvement is that the first cone, the second cone, the third cone, and the fourth cone have the same structure, and each of the first cone, the second cone, the third cone, and the fourth cone includes a top cover and a cone block. The top cover is provided on the cone block, and the outer side of the cone block is provided with an inclined sliding groove. The inclined sliding block is adapted to the inclined sliding groove.

[0013] A further improvement is made in that: a first linkage rod is connected between the first cone and the second cone, a second linkage rod is connected between the third cone and the fourth cone, an extension rod is connected between the second cone and the third cone, the first seat and the second seat are connected, and the third seat and the fourth seat are connected.

[0014] A further improvement is that the filter bag has an inner sealing cloth, and the first connecting rod and the second connecting rod pass through the inside of the filter bag and are connected to the filter bag through the sealing cloth.

[0015] A bag filter includes a filter bag cleaning device and a frame for air pollution. The first and second bases are hoisted and fixed at the upper position of the frame, and the third and fourth bases are hoisted and fixed at the lower position of the frame. The filter bag passes through the frame, and the opening of the frame for the filter bag to pass through is provided with a sealing airbag.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. In this invention, a filter bag is fitted onto the outer side of the first and second connecting rods. A conical component synchronously drives the first, second, third, and fourth moving blocks to move. The first and second moving blocks move in opposite directions, while the first and third moving blocks move in the same direction. The fourth moving block moves in opposite directions to the third moving block, and in the same direction as the second moving block. This movement mode drives the first and second connecting rods to move synchronously in opposite directions, causing four points of the filter bag to extend outwards synchronously, while the other four points contract inwards synchronously. Conversely, the same applies. Through this alternating extension and retraction movement, the filter bag is thoroughly rubbed, which can quickly and thoroughly remove dust adhering to the surface of the filter bag. The dust removal effect is good, and there is no need for manual rubbing of the filter bag, which greatly reduces the labor intensity of the workers and improves the dust removal efficiency.

[0018] 2. The first cone, second cone, third cone, and fourth cone of the present invention are respectively movably disposed inside the first base, second base, third base, and fourth base, and are synchronously connected by the first linkage rod, second linkage rod, and extension rod. Only one cylinder is needed as a power source to drive the first cone, second cone, third cone, and fourth cone to move synchronously, thereby synchronously driving the first moving block, second moving block, third moving block, and fourth moving block to achieve uniform rubbing and dust removal of the filter bag. The single power source drive design simplifies the equipment structure, reduces the number of power sources used, and lowers the equipment manufacturing and maintenance costs. At the same time, it ensures the synchronicity of the movement of each cone, avoiding problems such as component jamming and uncoordinated movement. It is easy to operate, without complicated operating steps, and greatly improves the convenience and stability of operation.

[0019] 3. When this invention is applied to a baghouse dust collector, the conical component is in the neutral position during operation. At this time, the first, second, third, and fourth moving blocks are in a balanced position, ensuring that the positions of the first and second connecting rods are consistent. This effectively guarantees the circular structure of the filter bag, maximizes the filtration area of ​​the filter bag, and improves dust removal efficiency. During dust removal, the airflow enters the frame and passes through the filter bag from the outside. Dust is trapped by the filter bag, and the purified gas is discharged from the top or bottom of the filter bag, thus achieving efficient dust removal. Because the frame has a sealing airbag at the opening through which the filter bag passes, the airbag can seal the connection between the filter bag and the frame after inflation, preventing dust-laden airflow from leaking through gaps. This ensures that all airflow passes through the filter bag from the outside, guaranteeing the dust removal effect. During cleaning, the sealing airbag releases gas, releasing the seal on the filter bag and providing sufficient space for the rubbing motion of the filter bag. This ensures that rubbing and cleaning can proceed smoothly, achieving an orderly switch between dust removal and cleaning operations, further improving the overall operational stability and practicality of the baghouse dust collector.

[0027] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0028] Example 1

[0029] according to Figure 1 , 2As shown in Figures 3, 4, 5, and 6, this embodiment proposes a filter bag cleaning device for air pollution, including a base and a cone. The base includes a first base 1 and a second base 2 located at the top, and a third base 3 and a fourth base 4 located at the bottom. A first moving block 5, a second moving block 6, a third moving block 7, and a fourth moving block 8 are movably mounted at the four corners of the first base 1, the second base 2, the third base 3, and the fourth base 4, respectively. The first moving block 5 and the second moving block 6 are offset, and the first moving block 5 and the third moving block 7 correspond to and are connected by a first connecting rod 9. The fourth moving block 8 and the third moving block 7 are offset, and the fourth moving block 8 corresponds to and are connected by a second connecting rod 10. A filter bag 11 is sleeved on the outer side of the first connecting rod 9 and the second connecting rod 10. The first base 1, the second base 2, the third base 3, and the fourth base 4 are... 4. To provide a stable installation foundation for the entire device, the first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8 at the four corners can move flexibly along the base. The first moving block 5 and the third moving block 7 are connected by the first connecting rod 9, and the fourth moving block 8 and the second moving block 6 are connected by the second connecting rod 10, forming a symmetrical support structure. The filter bag 11 is fitted on the outside of the first connecting rod 9 and the second connecting rod 10. The filter bag 11 is supported by the two connecting rods, ensuring the structural stability of the filter bag 11 after it is unfolded, and providing a structural foundation for subsequent scrubbing and dust removal. During use, the conical part is in the middle position. At this time, the first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8 are in the balanced position, so that the positions of the first connecting rod 9 and the second connecting rod 10 are consistent, which can effectively ensure the circular structure of the filter bag 11 and ensure that the filtration area of ​​the filter bag 11 is maximized.

[0030] The conical component is used to synchronously drive the first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8. The first moving block 5 moves in opposite directions to the second moving block 6, and the first moving block 5 and the third moving block 7 move in the same direction. The fourth moving block 8 moves in opposite directions to the third moving block 7, and the fourth moving block 8 moves in the same direction as the second moving block 6. As the core of power transmission, the conical component synchronously drives the four moving blocks in specific directions, namely, the first moving block 5 moves in opposite directions to the second moving block 6, the first moving block 5 moves in the same direction as the third moving block 7, the fourth moving block 8 moves in opposite directions to the third moving block 7, and the fourth moving block 8 moves in the same direction as the second moving block 6. This drives the first connecting rod 9 and the second connecting rod 10 to move synchronously in opposite directions, thereby causing the filter bag 11 to alternately extend and retract, simulating a manual rubbing action to remove dust from the surface of the filter bag 11.

[0031] The conical component includes a first cone 12, a second cone 13, a third cone 14, and a fourth cone 15. These cones are movably disposed within the first seat 1, the second seat 2, the third seat 3, and the fourth seat 4, respectively, and move synchronously. Each cone drives a first moving block 5, a second moving block 6, a third moving block 7, and a fourth moving block 8. Each cone corresponds to and is fitted to one of the first seat 1, the second seat 2, the third seat 3, and the fourth seat 4, allowing for flexible movement within their respective seats. When the four cones move synchronously, they precisely drive the corresponding first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8, ensuring the synchronicity and coordination of the four moving blocks' movements, preventing jamming or misalignment, and guaranteeing the stability of the washing and cleaning process.

[0032] The inclined surfaces of the first cone 12 and the second cone 13 are opposite each other, as are the inclined surfaces of the third cone 14 and the fourth cone 15. The inclined surfaces of the first seat 1 and the second seat 2 are opposite each other, as are the inclined surfaces of the third seat 3 and the fourth seat 4. The opposite inclined surfaces of the first cone 12 and the second cone 13, and the third cone 14 and the fourth cone 15, combined with the opposite inclined surfaces of the first seat 1 and the second seat 2, and the third seat 3 and the fourth seat 4, ensure that the inclined surfaces of the cones precisely align with the inclined surfaces of the moving blocks during movement. This smoothly transforms the linear motion of the cones into the horizontal motion of the moving blocks, while simultaneously ensuring that the two oppositely positioned cones drive the corresponding moving blocks to move in opposite directions. This conforms to the motion patterns of the four moving blocks, providing a reasonable motion transmission structure for the scrubbing action.

[0033] A cylinder 16 is connected above the first cone 12. The cylinder 16 drives the first cone 12, the second cone 13, the third cone 14, and the fourth cone 15 to move synchronously. The cylinder 16, as the sole power source, is fixedly connected above the first cone 12. When the cylinder 16 extends or retracts, it drives the first cone 12 to move up and down. Through the linkage structure between the cones, it synchronously drives the second cone 13, the third cone 14, and the fourth cone 15 to move together. This eliminates the need for multiple power sources, simplifies the structure, ensures the synchronicity of the four cones' movements, reduces equipment operation and maintenance costs, and achieves efficient power transmission.

[0034] The first seat 1, the second seat 2, the third seat 3, and the fourth seat 4 have identical structures, and each of them includes an inner cone 18 and an edge 19. The edge 19 is located on the inner cone 18. The inner cone 18 has an inner cavity 20 that matches the cone component. The edge 19 has a T-slot 21 that matches the first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8. The identical structure of the four seats facilitates mass production and maintenance / replacement. The inner cavity 20 of the inner cone 18 matches the cone component, providing a stable space for its movement and ensuring smooth movement. The edge 19 is used to mount the moving blocks, and the T-slot 21 on it matches the T-shaped structure of the moving blocks, limiting and guiding the moving blocks to prevent them from shifting or falling off during movement, ensuring that the moving blocks slide smoothly in the specified direction.

[0035] The first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8 have the same structure, and each of them includes a T-shaped block 22 and an inclined slider 23. The T-shaped block 22 is movably adapted to the T-shaped groove 21, and the inclined slider 23 is located at the inner end of the T-shaped block 22. The four moving blocks have the same structure, which facilitates processing and replacement. The T-shaped block 22 is movably adapted to the T-shaped groove 21 along the edge 19 of the seat, realizing the sliding connection between the moving block and the seat, and at the same time playing a limiting role to prevent the moving block from detaching from the seat. The inclined slider 23 is adapted to the inclined sliding groove 26 of the cone component. When the cone component moves up and down, the inclined slider 23 slides in the inclined sliding groove 26, converting the vertical movement of the cone into the horizontal movement of the moving block, realizing the transmission of power, and driving the connecting rod and the filter bag 11 to move.

[0036] The first cone 12, the second cone 13, the third cone 14, and the fourth cone 15 have the same structure, and each of them includes a top cover 24 and a cone block 25. The top cover 24 is located on the cone block 25, and the outer side of the cone block 25 is provided with an inclined groove 26. The inclined slider 23 is adapted to the inclined groove 26. The four cones have the same structure, which facilitates processing, assembly, and maintenance. The top cover 24 is used to connect the linkage component and the power source (cylinder 16), ensuring that the cone is firmly connected to other components. The outer side of the cone block 25 is provided with an inclined groove 26, which is adapted to the inclined slider 23 of the moving block. Power transmission is achieved through inclined surface contact. When the cone moves up and down, the inclined groove 26 pushes the inclined slider 23 to move horizontally, thereby driving the moving block to move, ensuring smooth and efficient power transmission and avoiding jamming.

[0037] A first linkage rod 27 connects the first cone 12 and the second cone 13; a second linkage rod 28 connects the third cone 14 and the fourth cone 15; an extension rod 29 connects the second cone 13 and the third cone 14; the first seat 1 and the second seat 2 are connected; and the third seat 3 and the fourth seat 4 are connected. The first linkage rod 27 connects the first cone 12 and the second cone 13 to ensure their synchronous movement; the second linkage rod 28 connects the third cone 14 and the fourth cone 15 to ensure their synchronous movement; the extension rod 29 connects the second cone 13 and the third cone 14 to achieve synchronous linkage between the upper and lower cones, thereby ensuring the overall synchronous movement of the four cones; the first seat 1 is connected to the second seat 2, and the third seat 3 is connected to the fourth seat 4, respectively, to enhance the overall structural stability of the seat components, provide reliable support for the movement of the cone components and moving blocks, and prevent shaking during equipment operation.

[0038] The filter bag 11 has an inner sealing cloth 17. The first connecting rod 9 and the second connecting rod 10 pass through the inside of the filter bag 11 and are connected to the filter bag 11 through the sealing cloth 17. The sealing cloth 17 is placed inside the filter bag 11 to enhance the connection strength between the filter bag 11 and the first connecting rod 9 and the second connecting rod 10, and to prevent the filter bag 11 from rubbing, falling off or being damaged during the rubbing motion. The first connecting rod 9 and the second connecting rod 10 pass through the inside of the filter bag 11 and are connected through the sealing cloth 17 to ensure that the filter bag 11 can be firmly fixed on the connecting rod and perform the rubbing action with the extension and retraction of the connecting rod. At the same time, the sealing cloth 17 can reduce the local wear of the filter bag 11 by the connecting rod and extend the service life of the filter bag 11.

[0039] Example 2

[0040] according to Figure 1 , 2As shown in Figures 3, 4, 5, and 6, this embodiment proposes a bag filter dust collector, including a filter bag cleaning device for atmospheric pollution and a frame 30. The first base 1 and the second base 2 are hoisted and fixed at the upper position of the frame 30, and the third base 3 and the fourth base 4 are hoisted and fixed at the lower position of the frame 30. The filter bag 11 passes through the frame 30, and a sealing airbag 31 is provided at the opening of the frame 30 through which the filter bag 11 passes. The frame 30 provides overall installation support for the entire bag filter and filter bag cleaning device. The first support body 1 and the second support body 2 are hoisted above the frame 30, and the third support body 3 and the fourth support body 4 are hoisted below the frame 30, so that the filter bag 11 can be vertically suspended and pass through the frame 30 to form a stable filtration structure. A sealing airbag 31 is set at the opening where the filter bag 11 passes through the frame 30. During dust removal operation, the sealing airbag 31 inflates and expands, tightly fitting the filter bag 11 and the inner wall of the opening of the frame 30 to achieve a seal between the two, preventing the dust-laden airflow from leaking from the gaps, and ensuring that all airflow must pass through the filter bag 11 from the outside, thus ensuring dust removal efficiency. During cleaning operation, the sealing airbag 31 discharges gas, releasing the seal, leaving sufficient space for the rubbing and stretching movement of the filter bag 11, avoiding friction damage between the filter bag 11 and the opening of the frame 30 during movement, ensuring smooth cleaning operation, and realizing the orderly switching between dust removal and cleaning.

[0041] The filter bag cleaning device and bag filter dust collector for air pollution has a filter bag 11 fitted on the outside of the first connecting rod 9 and the second connecting rod 10. A conical component synchronously drives the first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8. The first moving block 5 moves in opposite directions to the second moving block 6, the first moving block 5 and the third moving block 7 move in the same direction, and the fourth moving block 8 moves in opposite directions to the third moving block 7, and the fourth moving block 8 moves in the same direction as the second moving block 6. This movement causes the first connecting rod 9 and the second connecting rod 10 to move synchronously in opposite directions, causing four points on the filter bag 11 to extend outwards synchronously, and the other four points to contract inwards synchronously, and vice versa. Through this alternating extension and retraction movement, the filter bag 11 is thoroughly rubbed, quickly and completely removing dust adhering to its surface. The cleaning effect is excellent, eliminating the need for manual rubbing of the filter bag 11, significantly reducing the labor intensity of workers and improving cleaning efficiency. The first cone 12, the second cone 13, the third cone 14, and the fourth cone 15 of this invention are respectively movably disposed inside the first seat 1, the second seat 2, the third seat 3, and the fourth seat 4, and are synchronously connected by the first linkage rod 27, the second linkage rod 28, and the extension rod 29. Only one cylinder 16 is needed as a power source to drive the first cone 12, the second cone 13, the third cone 14, and the fourth cone 15 to move synchronously, thereby synchronously driving the first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8 to move, so as to achieve uniform rubbing and dust removal of the filter bag 11. The single power source drive design simplifies the equipment structure, reduces the number of power sources used, and reduces the equipment manufacturing and maintenance costs. At the same time, it ensures the synchronicity of the movement of each cone, avoids the problems of component jamming and uncoordinated movement, and is easy to operate without complicated operation steps, which greatly improves the convenience and stability of operation. When this invention is applied to a baghouse dust collector, the conical component is in the neutral position during operation. At this time, the first moving block 5, the second moving block 6, the third moving block 7, and the fourth moving block 8 are in a balanced position, ensuring that the positions of the first connecting rod 9 and the second connecting rod 10 are consistent. This effectively guarantees the circular structure of the filter bag 11, maximizing the filtration area of ​​the filter bag 11 and improving dust removal efficiency. During dust removal operation, the airflow enters the frame 30 and passes through the filter bag 11 from the outside. Dust is trapped by the filter bag 11, and the purified gas is discharged from above or below the filter bag 11, thereby achieving high efficiency. The purpose of dust removal is as follows: Since the frame 30 has a sealing airbag 31 at the opening through which the filter bag 11 passes, the sealing airbag 31 can seal the filter bag 11 and the frame 30 after being inflated, preventing the dust-laden airflow from leaking out of the gaps and ensuring that all airflow passes through the filter bag 11 from the outside, thus ensuring the dust removal effect. During cleaning, the sealing airbag 31 discharges gas, releasing the seal on the filter bag 11 and leaving sufficient space for the rubbing and washing movement of the filter bag 11, ensuring that the rubbing and washing can be carried out smoothly, realizing the orderly switching between dust removal and cleaning operations, and further improving the overall operational stability and practicality of the bag filter.
