Description

Technical Field

[0001] This utility model relates to the field of bag filter technology, and in particular to a pulse jet cleaning device for bag filters. Background Technology

[0002] A bag filter is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the bag filter, larger and heavier dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is trapped, thus purifying the gas.

[0003] After purifying dust, baghouse dust collectors require regular cleaning of the filter bags inside. Pulse jet cleaning is used to remove dust from the filter bags through pulse vibration. However, the dust settles naturally after falling, which is time-consuming. Furthermore, the dust can fall back onto the filter bags during its dispersal, affecting the cleaning effect. Therefore, a pulse jet cleaning device for baghouse dust collectors is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pulse jet cleaning device for baghouse dust collectors, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the suction blocking assembly includes a blocking plate fixedly sleeved on the rotating shaft, and the blocking plate is adapted to both the vent hole and the collection frame.

[0008] Preferably, an end baffle is fixedly installed on one side of the baffle plate, the end baffle is horizontally arranged with the baffle plate, and an arc-shaped ash hole is opened on the bottom inner wall of the vent hole, the arc-shaped ash hole is connected to the collection frame, and the end baffle is adapted to the arc-shaped ash hole.

[0009] Preferably, the positioning component includes an adjusting block fixedly sleeved on the rotating shaft, and a positioning bolt is movably mounted on the adjusting block, the positioning bolt being connected to the collection frame.

[0010] Preferably, a first bolt groove and a second bolt groove are provided on one side of the collection frame. Both the first bolt groove and the second bolt groove are adapted to the positioning bolt, and one end of the positioning bolt is threaded into the first bolt groove.

[0011] Preferably, the pulse blowing assembly includes an air storage tank installed on one side of the dust collector body, an electromagnetic pulse valve connected to the air storage tank, a blow pipe connected to one side of the electromagnetic pulse valve, and multiple blow holes on one side of the blow pipe, each of the multiple blow holes being adapted to multiple filter bag bodies.

[0012] Preferably, the bottom side of the dust collector body is equipped with multiple support legs, and the bottom ash discharge plate is installed on the bottom side of the collection frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the pulse jet cleaning device for bag dust collector is equipped with a pulse blowing component, which generates shock waves through the pulse of compressed air, causing the filter bag body to vibrate, causing the dust layer accumulated on the filter bag body to fall off. When the suction fan is started, the dust that is shaken off the filter bag body will enter the air vent under the action of suction force and be blocked and filtered by the filter plate, thereby quickly collecting and processing the shaken-off dust, preventing the shaken-off dust from falling back onto the filter bag body, and greatly reducing the cleaning time;

[0014] After the dust removal is completed, the staff rotates the adjusting block again to rotate the baffle plate into the vent hole. After adjustment, the positioning bolt is threaded into the second bolt groove to block the adjusted baffle plate. At this time, the end baffle will rotate to the lower position, and the arc-shaped dust outlet will be open. After the dust on the filter plate falls, it will fall into the collection frame through the arc-shaped dust outlet. Open the bottom dust discharge plate to process the collected dust.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Refer to Figure 1-5 A pulse jet cleaning device for a bag filter includes a dust collector body 1, a filter bag body 2 inside the dust collector body 1, an inlet pipe 3 and an outlet pipe 4 on both sides of the dust collector body 1, and a pulse jet cleaning assembly on the dust collector body 1. The pulse jet cleaning assembly includes an air storage tank 5 installed on one side of the dust collector body 1, an electromagnetic pulse valve 6 connected to the air storage tank 5, a jet pipe 7 connected to one side of the electromagnetic pulse valve 6, and multiple jet holes on one side of the jet pipe 7. The multiple jet holes are adapted to multiple filter bag bodies 2. The filter bag bodies 2 have a lot of dust and need to be cleaned. The pulse jet cleaning assembly is equipped with an electromagnetic pulse valve 6 that is switched on and off, and the air in the air storage tank 5 is cleaned. The dust collector body 1 is connected to a lower ash hopper 8 at the bottom of the dust collector body 1. A collection frame 9 is connected to the lower ash hopper 8 at the bottom of the lower ash hopper 8. A vent hole 13 is opened on one side of the inner wall of the collection frame 9. A suction fan 12 is installed on one side of the collection frame 9. The suction fan 12 is located on one side of the vent hole 13. A filter plate 14 is installed in the vent hole 13. A rotating shaft 15 is rotatably installed in the vent hole 13. A suction blocking component is provided on the rotating shaft 15. One end of the rotating shaft 15 extends to the outside of the collection frame 9 and is provided with a positioning component. Multiple support legs 11 are installed on the bottom side of the dust collector body 1.

[0023] Specifically, the suction blocking assembly includes a blocking plate 16 fixedly sleeved on the rotating shaft 15. The blocking plate 16 is adapted to both the vent 13 and the collection frame 9. An end baffle 17 is fixedly installed on one side of the blocking plate 16, and the end baffle 17 is horizontally arranged with the blocking plate 16. An arc-shaped ash discharge hole 18 is opened on the bottom inner wall of the vent 13, and the arc-shaped ash discharge hole 18 is connected to the collection frame 9. The end baffle 17 is adapted to the arc-shaped ash discharge hole 18. A bottom ash discharge plate 10 is installed on the bottom side of the collection frame 9. When the suction fan 12 is started, the filter bag body 2... The shaken-off dust will enter the vent 13 under the action of suction and be blocked and filtered by the filter plate 14, thus quickly collecting and processing the shaken-off dust and preventing the shaken-off dust from falling back onto the filter bag body 2, greatly reducing the dust cleaning time. After the dust cleaning is completed, the end baffle 17 will rotate to the lower position, and the arc-shaped lower dust hole 18 will be in the open state. After the dust on the filter plate 14 falls, it will fall into the collection frame 9 through the arc-shaped lower dust hole 18. Open the bottom dust discharge plate 10 to process the collected dust.

[0024] Specifically, the positioning component includes an adjusting block 19 fixedly sleeved on the rotating shaft 15. A positioning bolt 20 is movably mounted on the adjusting block 19 and is connected to the collection frame 9. A first bolt groove 21 and a second bolt groove 22 are provided on one side of the collection frame 9. Both the first bolt groove 21 and the second bolt groove 22 are adapted to the positioning bolt 20. One end of the positioning bolt 20 is threaded into the first bolt groove 21. The operator rotates the positioning bolt 20 on the positioning component to disengage it from the second bolt groove 22, and then rotates the adjusting block 19 to... The rotating shaft 15 rotates, causing the baffle plate 16 to rotate. The baffle plate 16 moves from the vent 13 into the collection frame 9, forming a blockage inside the collection frame 9. The dust below the collection frame 9 will not be sucked away by the suction generated by the suction fan 12. At the same time, the end baffle 17 also blocks the arc-shaped lower dust hole 18. After the dust is cleaned, the staff rotates the adjusting block 19 again to make the baffle plate 16 rotate into the vent 13. After adjustment, the positioning bolt 20 is threaded into the second bolt groove 22, which can block the position of the adjusted baffle plate 16.

[0025] During use: After prolonged dust filtration, the filter bag body 2 inside the dust collector body 1 accumulates a significant amount of dust and requires cleaning. The pulse blowing assembly operates, with the electromagnetic pulse valve 6 on the assembly switching on and off. Gas from the air tank 5 passes through the blowpipe 7, and the compressed air pulse generates shock waves, causing the filter bag body 2 to vibrate and dislodge the accumulated dust layer. At this time, the operator rotates the positioning bolt 20 on the positioning assembly, disengaging it from the second bolt slot 22, and rotates the adjusting block 19, thereby rotating the rotating shaft 15 and the baffle plate 16. The baffle plate 16 moves from the vent 13 into the collection frame 9, blocking the dust below the collection frame 9. This prevents the dust from being sucked away by the suction generated by the fan 12. Simultaneously, the end baffle 17 also blocks the dust from the arc-shaped lower dust hole 18. When the suction fan 12 is started, the dust shaken off from the filter bag body 2 will enter the vent 13 under the suction force and be blocked and filtered by the filter plate 14. This allows for the rapid collection and treatment of the shaken-off dust, preventing it from falling back onto the filter bag body 2 and greatly reducing the dust cleaning time. After dust cleaning, the operator rotates the adjusting block 19 again to rotate the blocking plate 16 into the vent 13. After adjustment, the positioning bolt 20 is threaded into the second bolt groove 22 to block the adjusted blocking plate 16. At this time, the end baffle 17 will rotate to the lower position, and the arc-shaped lower dust hole 18 will be open. The dust falling off the filter plate 14 will fall into the collection frame 9 through the arc-shaped lower dust hole 18. Opening the bottom dust discharge plate 10 allows for the collection and treatment of the dust, making it convenient to use.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
