Description

Technical Field

[0001] This invention belongs to the technical field of dust removal and circulation devices, and more specifically, relates to a self-cleaning dust removal and circulation device for pipe pile production. Background Technology

[0002] As a crucial component of building foundations, the production of pipe piles involves processes such as concrete mixing, placement, and centrifugal molding, all of which generate significant amounts of dust-laden waste gas. This waste gas is rich in pollutants such as cement particles and mineral dust. Without efficient treatment, it not only severely pollutes the workshop environment and threatens worker health but also leads to accelerated equipment wear and reduced product yield. Currently, dust removal technology in pipe pile production workshops faces the following key challenges:

[0003] Maintenance bottlenecks of traditional dust removal devices:

[0004] Most dust removal equipment relies on multi-stage filters (such as bag filters) to intercept dust, but dust easily accumulates on the surface of the filter bags, leading to increased air resistance and a sharp drop in filtration efficiency. Current technologies typically require shutdown and manual cleaning of the filter bags, which is cumbersome and frequent disassembly can damage the filter bag's sealing structure, shortening the equipment's lifespan. For example, at the pipe pile formwork cleaning station, the sticky dust formed by the mixture of sprayed formwork oil mist and concrete residue is even more difficult to remove; manual cleaning is inefficient and disrupts production continuity.

[0005] Incomplete dust removal and the risk of secondary pollution:

[0006] Conventional pulse-jet cleaning technology uses a high-pressure airflow to vertically impact the filter bag, which can remove some loose dust, but its effectiveness is limited in removing fine particles or sticky impurities embedded deep within the filter bag fibers. Incomplete cleaning can lead to an irreversible decrease in the filter bag's permeability, requiring premature replacement and increasing costs. Furthermore, traditional mechanical vibration cleaning can easily cause secondary dust re-entrainment, resulting in secondary air pollution in the workshop.

[0007] The contradiction between energy consumption and structural reliability:

[0008] To improve dust removal efficiency, some equipment incorporates rotating filter bags or mechanical beaters, but these often rely on additional motors, leading to increased energy consumption. The complex transmission structure not only occupies space but also exacerbates mechanical wear due to frequent movements, requiring regular maintenance. For example, the hydraulic lifting system in pipe mold transfer equipment has been criticized for its high energy consumption and maintenance costs. Furthermore, the existing sealing structure of rotating filter bags is prone to air leakage during dynamic rotation, disrupting the negative pressure environment of the dust removal system and affecting airflow stability.

[0009] Low level of intelligence and waste of resources:

[0010] Most dust removal equipment lacks coordinated control between airflow distribution and dust removal actions, resulting in concentrated energy consumption in a single process. For example, high-pressure air pumps are only used for pulse jet cleaning, failing to fully utilize airflow energy to drive rotation or tapping mechanisms, leading to low energy efficiency. Summary of the Invention

[0011] To address the aforementioned technical problems, this invention provides a self-cleaning dust removal and circulation device for pipe pile production, which solves the significant shortcomings of existing pipe pile production dust removal technologies in terms of dust removal efficiency, resource utilization, filter bag protection, and automated dust removal.

[0012] A self-cleaning dust removal and circulation device for pipe pile production includes a dust removal and circulation machine. A support frame is installed inside the dust removal and circulation machine, and a processing box is mounted on the support frame. A dust collection bag is installed at the bottom of the processing box. Several rows of side-shifting and tapping mechanisms and rotating filter bag assemblies are installed inside the processing box. Each side-shifting and tapping mechanism is located between two rows of rotating filter bag assemblies. Each side-shifting and tapping mechanism includes a partition frame and a main moving frame. Each main moving frame is embedded on the left and right sides of the partition frame. Several tail fixing plates are installed on the side walls of each main moving frame. Each main moving frame and tail fixing plate are used to assist in cleaning the rotating filter bag assemblies. Each rotating filter bag assembly includes a filter bag. An outer ring frame is fixed to the top of each filter bag and is inserted into an upper sealing ring frame. An inclined plate is fixed to the side wall of each outer ring frame. A second air pipe is installed on each upper sealing ring frame.

[0013] Preferably, a high-pressure air pump is fixed to the side wall of the processing chamber, an upper fixed frame is fixed inside the processing chamber, and each rotating filter bag assembly is installed below the upper fixed frame. The top of each filter bag is connected to the top of the outer ring frame. Several high-pressure air pipes are provided on the high-pressure air pump, and several gas injection heads are installed on each high-pressure air pipe. Each gas injection head is located at the center of the top of the main moving frame. A first groove is opened on both sides of each partition frame, and an exhaust groove is opened on the inner wall of each first groove. A first air pipe connected to the high-pressure air pipe is installed on the top of each partition frame, and the first air pipe is connected to each exhaust groove.

[0014] Preferably, each main moving frame is located in the first groove, and the shape of the back of each main moving frame is adapted to the first groove. Magnetic blocks are fixed on both sides of the back of each main moving frame, and the magnetic blocks are magnetically attracted to the inner wall of the first groove. Each main moving frame has a spring frame on its back, and each spring frame is connected to the inner wall of the first groove. Several second grooves are opened on the side wall of each main moving frame, and each tail fixing plate is located in the second groove. A first spring is connected between the back of each tail fixing plate and the inner wall of the second groove. A front baffle is provided on the front side of each tail fixing plate, and a rubber pad is installed between each front baffle and the tail fixing plate. Several impact spikes are fixed on the front side of each front baffle.

[0015] Preferably, the top of each second air tube is connected to the high-pressure air tube, and the portion of each second air tube located on the inner wall of the upper sealing ring frame is a corner arc, with the corner facing the inclined plate. A lower sealing ring is installed at the bottom of each upper sealing ring frame, and the upper sealing ring frame and the lower sealing ring seal the outer ring frame. An annular retaining ring is fixed on the upper surface of each lower sealing ring. A fixing block is fixed on the side wall of each outer ring frame, and a second spring is fixed between the end of the fixing block and the annular retaining ring. A gap is formed between the fixing block and the inclined plate. A gap is also provided between the other end of the annular retaining ring and the inclined plate. The corner end of the bottom of the second air tube is located between the annular retaining ring and the inclined plate. Several vent holes are opened through the side wall of the upper sealing ring frame, and the vent holes are located at the center between the inclined plate and the fixing block.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, a large amount of waste gas is generated during the production of pipe piles. This waste gas contains a large number of impurities and pollutants. The waste gas is transported to the treatment chamber through an inlet pipe. Inside the treatment chamber, the waste gas encounters multiple sets of rotating filter bag assemblies. The filter bags in the rotating filter bag assemblies purify the waste gas. Simultaneously, the waste gas continues to flow upwards and is discharged through an exhaust pipe. A large amount of dust particles accumulate on the surface of the filter bags. At this point, a high-pressure air pump is activated. The high-pressure air pump delivers high-pressure pulsed air pressure to the gas injection head through multiple high-pressure air pipes. The gas injection head discharges the high-pressure gas in a pulsed manner. The high-pressure gas rapidly impacts downwards through the top of the gas injection head and passes through the iron mesh frame to the filter bags. The impact causes surface dust to fall off quickly. At the same time, high-pressure gas delivered by the high-pressure air pipe enters the upper sealing ring frame. The high-pressure gas in the upper sealing ring frame drives the filter bag to rotate repeatedly through the outer ring frame. Simultaneously, high-pressure gas delivered by the high-pressure air pipe enters the separator frame, repeatedly pushing the main moving frame outward to clean the filter bag again. This effectively cleans the dust on the surface of the filter bag, and the dust falls into the dust collection bag. By using the high-pressure pulse air pressure of the high-pressure air pump to control the filter bag to perform multiple dust cleanings, the cleaning power is more thorough during self-cleaning, improving cleaning ability and extending the service life of the filter bag.

[0018] In this invention, multiple high-pressure air pipes are used to control multiple gas injection heads, separators, and upper sealing rings, thereby effectively utilizing resources and eliminating the need for additional high-pressure air pumps for individual driving. This greatly improves the overall coordination and dust removal efficiency.

[0019] In this invention, a high-pressure gas pipe transmits high-pressure gas to the separator frame through a first gas pipe. The high-pressure gas enters the first groove, and the high-pressure gas in the first groove rapidly ejects multiple main moving frames. When the main moving frames move away from the separator frame, the high pressure in the first groove disappears. Subsequently, multiple elastic frames and magnetic blocks pull the main moving frames back into the separator frame. When the next high-pressure gas is emitted, the multiple main moving frames leave the separator frame again, thus completing the reciprocating movement. The elastic frames and magnetic blocks fix the main moving frames in the first groove, so that the high-pressure gas in the first groove, after reaching a certain pressure, rapidly propels the main moving frames out. The multiple main moving frames move outward and quickly impact the surface of the filter bag, which can knock off the particles on the surface of the filter bag, improving the efficiency of particle cleaning.

[0020] In this invention, the main moving frame drives multiple tail fixing plates on the surface to move outward. The outward movement of the multiple tail fixing plates causes multiple impact cones on the surface to impact the filter bag surface. The impact of the multiple impact cones on the filter bag surface is more delicate and can clean more complex dust particles. At the same time, a first spring is provided between each tail fixing plate and the inner wall of the main moving frame. Therefore, when the tail fixing plate impacts the filter bag, the first spring can form a certain buffer distance to prevent damage to the filter bag. In addition, a rubber pad is provided between the front baffle and the tail fixing plate. The rubber pad can be compressed to a certain extent, further providing buffering force when the impact cones impact. While cleaning, the surface of the filter bag is protected, forming a biomimetic hand-grabbing dust cleaning.

[0021] In this invention, a high-pressure air pipe transmits high-pressure gas into the upper sealing ring frame through a second air pipe. The bottom corner of the second air pipe sprays the high-pressure gas toward the inclined plate. At this time, the inclined plate moves under force, causing the outer ring frame to rotate. The rotation of the outer ring frame causes the filter bag to rotate, and the rotation of the outer ring frame causes the fixing block to rotate, compressing the second spring. When the inclined plate rotates to the vent hole opened in the upper sealing ring frame, the high-pressure gas leaks through the vent hole. At this time, the high-pressure gas is insufficient, and the second spring causes the outer ring frame to rotate in the opposite direction to reset. This process is repeated, and the filter bag will rotate in both directions. The rotation of the filter bag can throw the dust outward, improving the dust removal efficiency of the filter bag in the same time. Attached Figure Description

[0033] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0034] Example 1: Please refer to Figures 1-10This invention provides a self-cleaning dust removal and circulation device for pipe pile production, including a dust removal and circulation machine 1. A support frame 11 is installed inside the dust removal and circulation machine 1. A processing box 13 is installed on the support frame 11. A dust collection bag 12 is installed at the bottom of the processing box 13. Several rows of side-shifting and picking mechanisms 2 and rotating filter bag assemblies 34 are installed inside the processing box 13. Each side-shifting and picking mechanism 2 is located between two rows of rotating filter bag assemblies 34. Each side-shifting and picking mechanism 2 includes a partition frame 21 and a main moving frame 25. Each main moving frame 25 is embedded in the left and right sides of the partition frame 21. Several tail fixing plates 29 are installed on the side walls of each main moving frame 25. Both the 5 and the tail fixing plate 29 are used to assist in cleaning the rotating filter bag assembly 34. Each rotating filter bag assembly 34 includes a filter bag 35. Each filter bag 35 has an outer ring frame 37 fixed to its top, and the outer ring frame 37 is inserted into the upper sealing ring frame 43. Each outer ring frame 37 has a slanted plate 38 fixed to its side wall. Each upper sealing ring frame 43 has a second air pipe 44 installed on it. An air inlet pipe 15 is installed at the bottom right side of the treatment box 13, and an exhaust pipe is installed at the top left side of the treatment box 13. During use, a large amount of waste gas is generated during the production of pipe piles. The waste gas contains a large amount of impurities and pollutants. The waste gas is transported into the treatment box 13 through the air inlet pipe 15. The exhaust gas encounters multiple sets of rotating filter bag assemblies 34 inside the treatment chamber 13. The filter bags 35 inside the rotating filter bag assemblies 34 purify the exhaust gas. Simultaneously, the exhaust gas continues to flow upwards and is discharged through the exhaust pipe. A large amount of dust particles accumulate on the surface of the filter bags 35. At this point, the high-pressure air pump 14 is activated. The high-pressure air pump 14 delivers high-pressure pulsed air pressure to the gas injection head 19 through multiple high-pressure air pipes 18. The gas injection head 19 discharges the high-pressure gas in a pulsed manner. The high-pressure gas rapidly impacts downwards through the top of the gas injection head 19. The high-pressure gas passes through the iron mesh frame 36 and impacts the dust on the surface of the filter bags 35, causing the dust to fall off quickly. At the same time, the high-pressure... High-pressure gas delivered by the air pipe 18 enters the upper sealing ring frame 43. Within the upper sealing ring frame 43, the high-pressure gas drives the filter bag 35 to rotate repeatedly through the outer ring frame 37. Simultaneously, high-pressure gas delivered by the high-pressure air pipe 18 enters the separator frame 21. The high-pressure gas pushes the main moving frame 25 outward repeatedly, cleaning the filter bag 35 again. This effectively cleans the dust from the surface of the filter bag 35, and the dust falls into the dust collection bag 12. By using the high-pressure pulse air pressure of the high-pressure air pump 14 to control the filter bag 35 to perform multiple dust cleanings, the cleaning power is more thorough during self-cleaning, improving cleaning ability and extending the service life of the filter bag 35.

[0035] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3A high-pressure air pump 14 is fixed to the side wall of the processing chamber 13. An upper fixed frame 17 is fixed inside the processing chamber 13, and each rotating filter bag assembly 34 is installed below the upper fixed frame 17. Each partition frame 21 is fixed below the upper fixed frame 17, and the top of each filter bag 35 is connected to the top of the outer ring frame 37. Several high-pressure air pipes 18 are provided on the high-pressure air pump 14, and several gas injection heads 19 are installed on each high-pressure air pipe 18. Each gas injection head 19 is located at the center of the top of the main moving frame 25. Each partition frame... Both sides of the partition frame 21 are provided with first grooves 22, and the inner wall of each first groove 22 is provided with exhaust grooves 23. The top of each partition frame 21 is equipped with a first air pipe 24 connected to the high-pressure air pipe 18, and the first air pipe 24 is connected to each exhaust groove 23. In use, multiple high-pressure air pipes 18 are used to control multiple gas injection heads 19, partition frames 21 and upper sealing ring frames 43, thereby effectively utilizing resources and eliminating the need to use more high-pressure air pumps 14 for individual driving, which greatly improves the uniformity and coordination and improves the dust removal efficiency.

[0036] Example 3: Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6Each main moving frame 25 is located within the first groove 22, and the shape of the back of each main moving frame 25 is adapted to the first groove 22. Magnets 26 are fixed to both sides of the back of each main moving frame 25, and the magnets 26 are magnetically attracted to the inner wall of the first groove 22. A spring frame 27 is provided on the back of each main moving frame 25, and each spring frame 27 is connected to the inner wall of the first groove 22. Several second grooves 28 are provided on the side walls of each main moving frame 25, and each tail fixing plate 29 is located within a second groove 28. A first spring 33 is connected between the back of each tail fixing plate 29 and the inner wall of the second groove 28. A front baffle 31 is provided on the front side of each tail fixing plate 29, and a rubber pad 3 is installed between each front baffle 31 and the tail fixing plate 29. Several impact spikes 32 are fixed on the front side of each front baffle 31. During use, the high-pressure air pipe 1... 8. High-pressure gas is transmitted to the separator 21 through the first gas pipe 24. The high-pressure gas enters the first groove 22. The high-pressure gas in the first groove 22 quickly ejects multiple main moving frames 25. When the main moving frames 25 move away from the separator 21, the high pressure in the first groove 22 disappears. Then, multiple elastic frames 27 and magnetic blocks 26 pull the main moving frames 25 back into the separator 21. When the high-pressure gas is released again, the multiple main moving frames 25 leave the separator 21 again, thus completing the reciprocating movement. The elastic frames 27 and magnetic blocks 26 fix the main moving frames 25 in the first groove 22, so that the high-pressure gas in the first groove 22, after a certain pressure, quickly ejects the main moving frames 25. The multiple main moving frames 25 move outward and quickly impact the surface of the filter bag 35, which can knock off the particles on the surface of the filter bag 35 and improve the efficiency of particle cleaning.

[0037] Example 4: Please refer to Figure 5 and Figure 6 When the main moving frame 25 moves outward, it drives multiple tail fixing plates 29 on the surface to move outward. The multiple tail fixing plates 29 move outward, causing multiple impact cones 32 on the surface to impact the surface of the filter bag 35. The impact of the multiple impact cones 32 on the surface of the filter bag 35 is more delicate, which can clean more complex dust particles. At the same time, a first spring 33 is provided between each tail fixing plate 29 and the inner wall of the main moving frame 25. Therefore, when the tail fixing plate 29 impacts the filter bag 35, the first spring 33 can form a certain buffer distance to prevent damage to the filter bag 35. Meanwhile, a rubber pad 3 is provided between the front baffle 31 and the tail fixing plate 29. The rubber pad 3 can be compressed to a certain extent, further providing buffering force when the impact cones 32 impact. While cleaning, it protects the surface of the filter bag 35, forming a biomimetic hand-grabbing dust cleaning.

[0038] Example 5: Please refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 Each second air pipe 44 has its top connected to the high-pressure air pipe 18, and the portion of each second air pipe 44 located on the inner wall of the upper sealing ring frame 43 is a curved corner, with the corner facing the inclined plate 38. A lower sealing ring 41 is installed at the bottom of each upper sealing ring frame 43, and the upper sealing ring frame 43 and the lower sealing ring 41 seal the outer ring frame 37. An annular retaining ring 42 is fixed to the upper surface of each lower sealing ring 41. A fixing block 39 is fixed to the side wall of each outer ring frame 37, and a second spring 4 is fixed between the end of the fixing block 39 and the annular retaining ring 42. A gap is formed between the fixing block 39 and the inclined plate 38. A gap is also provided between the other end of the annular retaining ring 42 and the inclined plate 38. The corner end of the bottom of the second air pipe 44 is located between the annular retaining ring 42 and the inclined plate 38. Several vents are provided through the side wall of the upper sealing ring frame 43. The vent hole 45 is located at the center between the inclined plate 38 and the fixing block 39. During use, the high-pressure air pipe 18 transmits high-pressure gas into the upper sealing ring frame 43 through the second air pipe 44. The bottom corner of the second air pipe 44 sprays the high-pressure gas toward the inclined plate 38. At this time, the inclined plate 38 moves under force, causing the outer ring frame 37 to rotate. The rotation of the outer ring frame 37 causes the filter bag 35 to rotate. The rotation of the outer ring frame 37 causes the fixing block 39 to rotate and compress the second spring 4. When the inclined plate 38 rotates to the vent hole 45 opened in the upper sealing ring frame 43, the high-pressure gas leaks through the vent hole 45. At this time, the high-pressure gas is insufficient, and the second spring 4 causes the outer ring frame 37 to rotate in the opposite direction to reset. This process is repeated, and the filter bag 35 will rotate in both directions. The rotation of the filter bag 35 can throw the dust outward, improving the dust removal efficiency of the filter bag 35 in the same time.
