Description

Technical Field

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

[0002] The pulse jet cleaning mechanism is the core cleaning device of the bag filter, which achieves efficient removal of dust from the surface of the filter bag through instantaneous jetting of high-pressure or low-pressure compressed air.

[0003] Among existing pulse cleaning mechanisms, the pulse rotor cleaning mechanism is the most common. It uses compressed air to rotate the rotor and clean and blow away the dust from the filter barrel.

[0004] The pulse rotor cleaning mechanism requires first fixing the frame to the equipment, and then inserting the components and filter bucket from the bottom and fixing them through the frame. The relatively small space inside the dust collector makes conventional bolt fixing inconvenient for installation and replacement. Therefore, a pulse cleaning mechanism for bag dust collectors is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pulse cleaning mechanism for a bag filter, which aims to improve the problem that the pulse rotor cleaning mechanism in the prior art cannot be installed quickly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pulse cleaning mechanism for a bag filter includes a fixed pipe, an air inlet pipe fixedly connected inside the fixed pipe, a fixed assembly installed on the outside of the air inlet pipe, a beater installed at the bottom of the fixed assembly, a second spring installed at the bottom of the beater, and an air jet assembly installed at the bottom of the second spring.

[0008] The fixing component includes a fixing frame, the fixing tube is slidably connected inside the fixing frame, a clamp is slidably connected inside the fixing frame, a stop bar is fixedly connected to the end of the clamp, a spring is sleeved on the outside of the stop bar, a fixing block is fixedly connected to the bottom of the fixing frame, and the clapper is slidably connected inside the fixing block.

[0009] As a further description of the above technical solution:

[0010] The jet assembly includes a fixed block two, which is fixedly connected to the bottom of the spring two. A rotating air pipe is rotatably connected to the bottom of the fixed block two, and the rotating air pipe is rotatably connected to the outside of the air intake pipe. Both ends of the rotating air pipe are fixedly connected to jet pipes.

[0011] As a further description of the above technical solution:

[0012] A slider is slidably connected to the outside of the air intake pipe, and the clamp head is engaged with the slider.

[0013] As a further description of the above technical solution:

[0014] The bottom of the fixed tube is provided with a slot, which is engaged with the slider.

[0015] As a further description of the above technical solution:

[0016] The fixed frame has a sliding groove inside, and the stop bar is slidably connected inside the sliding groove.

[0017] As a further description of the above technical solution:

[0018] A structural block is fixedly connected to the bottom of the air intake pipe, a contact is slidably connected inside the structural block, a spring is fixedly connected to the outside of the contact, and a soft block is fixedly connected to the end of the contact.

[0019] As a further description of the above technical solution:

[0020] The structural block has a second sliding groove inside, and the jet pipe is slidably connected inside the second sliding groove.

[0021] As a further description of the above technical solution:

[0022] A filter barrel is fitted on the outside of the jet assembly.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the fixing frame is first fixed inside the dust collector. Then, the air inlet pipe with the bottom jet assembly passes through the middle of the fixing frame from the bottom of the equipment. Then, the clamp head extends due to the spring and engages with the slider to quickly fix the jet assembly. When it needs to be replaced, simply push the air pipe upward to move the slider upward and compress the clamp head. The slider engages with the slot under the action of the clamp head. Then, the air inlet pipe is moved downward to remove the bottom jet assembly, achieving quick disassembly.

[0025] 2. In this utility model, the jet pipe, which rotates under the push of compressed air, slides in the groove inside the structural block, compressing the contact. The compressed contact causes the soft block at the end to extend out, thereby impacting and beating the filter barrel, further cleaning the dust that is difficult to blow off the filter barrel.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0036] Reference Figures 1-4One embodiment of this utility model is a pulse cleaning mechanism for a bag filter dust collector, which includes a fixed pipe 1. An air inlet pipe 3 is fixedly connected inside the fixed pipe 1. An external pulse valve is connected to the inlet of the fixed pipe 1. Compressed gas enters the dust collector from the air inlet pipe 3. The external components include a solenoid valve, compressed air storage, and other pulse exhaust devices. This is prior art and is not an improvement of this application, so it will not be described in detail here. The fixed pipe 1 protects the air intake pipe 3. A fixing component is installed on the outside of the air intake pipe 3 to fix the air intake pipe 3. A beater 11 is installed at the bottom of the fixing component. The beater 11 descends during operation to beat the bottom. A spring 12 is installed at the bottom of the beater 11. The spring 12 pushes the beater 11 back after beating. An air jet component is installed at the bottom of the spring 12 to blow away dust. The fixing component includes a fixing frame 2 and a dust removal device. First, the fixing frame 2 is fixed to the equipment. The fixing frame 2 is slidably connected to the outside of the fixed pipe 1. The fixed pipe 1 with the internal air intake pipe 3 passes through the middle of the fixing frame 2. A clamp 6 is slidably connected inside the fixing frame 2. A stop bar 8 is fixedly connected to the end of the clamp 6. A spring 7 is provided on the side sleeve, which rebounds the clamp head 6. A stop bar 8 prevents the spring 7 from popping the clamp head 6 out and restricts its movement. A groove 9 is provided inside the fixing frame 2. When the fixing tube 1 passes through the middle of the fixing frame 2, the fixing tube 1 compresses and contracts the clamp head 6. The stop bar 8 is slidably connected inside the groove 9. The compressed clamp head 6 drives the stop bar 8 to slide inside the groove 9. A slider 4 is slidably connected to the outside of the air intake pipe 3. The clamp head 6 and the slider 4 are interlocked. The fixing tube 1 passes through the middle of the fixing frame 2, compressing and contracting the clamp head 6. When the compressed clamp head 6 passes through the bottom of the fixing tube 1, it rebounds through the spring 7. The rebounding clamp head 6 abuts against the outside of the air intake pipe 3 and is interlocked with the slider 4 through the fixing tube 1, completing the quick installation.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The bottom of the fixed tube 1 is provided with a slot 5, which is engaged with the slider 4. When the air inlet tube 3 needs to be replaced, simply move the air inlet tube 3 upward, and the slider 4 will squeeze and retract the clamp head 6. The upward-moving air inlet tube 3 will drive the slider 4 to continue to move upward. When the slider 4 exceeds the clamp head 6, the clamp head 6 will spring back, and at the same time, the slider 4 will move upward. The upward-moving slider 4 will engage with the slot 5 at the bottom of the fixed tube 1. Then, the air inlet tube 3 will move downward, and the air inlet tube 3 will drive the slider 4 to move downward, squeezing and retracting the clamp head 6, thus removing the fixed tube 1 with the air inlet tube 3, achieving quick disassembly. The bottom of the fixed frame 2 is fixedly connected to a fixed block 10. The slidable connection of the slap 11 is inside the fixed block 10. When the slap 11 is slapped downward, it slides inside the fixed block 10.

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The jet assembly includes a fixing block 13, which is fixedly connected to the bottom of a spring 12, thus securing the spring 12. A rotating air pipe 14 is rotatably connected to the bottom of the fixing block 13. When external compressed gas enters the device through the inlet pipe 3, the gas enters the rotating air pipe 14 through the holes in the inlet pipe 3. The rotating air pipe 14 is rotatably connected to the outside of the inlet pipe 3. Jet pipes 15 are fixedly connected to both ends of the rotating air pipe 14. Compressed gas enters the jet pipes 15 through the rotating air pipe 14 and is ejected from the jet pipes 15. The rapidly ejected compressed gas causes the jet pipes 15 to push the rotating air pipe 14 to rotate, blowing away dust from the outside. Simultaneously, the internal air pressure of the equipment decreases, and the external pressure causes the beater 11 to quickly press down, beating and cleaning the equipment. A structural member is fixedly connected to the bottom of the inlet pipe 3. The structural block 20 has a contact 16 slidably connected inside, and a spring 17 is fixedly connected to the outside of the contact 16. The contact 16 extends and retracts through the spring 17. A soft block 18 is fixedly connected to the end of the contact 16. When the contact 16 is squeezed and contracted, the contact 16 drives the soft block 18 at the end to move and extend. The structural block 20 has a sliding groove 19 inside, and the jet pipe 15 is slidably connected inside the sliding groove 19. When compressed air quickly pushes the jet pipe 15 to rotate, the rotating jet pipe 15 slides in the sliding groove 19. The sliding jet pipe 15 squeezes and contracts the contact 16, pushing the soft block 18 at the end to extend. A filter barrel 21 is sleeved on the outside of the jet assembly. The extended soft block 18 impacts and beats the filter barrel 21 to further clean the dust that is difficult to blow off by the gas.

[0039] Working principle: First, the mounting bracket 2 is fixed to the equipment. The mounting tube 1, with the internal air inlet pipe 3, passes through the middle of the mounting bracket 2. The mounting tube 1 first compresses and contracts the clamp 6. When the compressed clamp 6 passes through the bottom of the mounting tube 1, it is rebounded by spring 7. The rebounded clamp 6 abuts against the outside of the air inlet pipe 3, and is engaged with the slider 4 through the mounting tube 1, thus fixing the air inlet pipe 3 and the bottom jet assembly, completing the quick installation. Then, the external pulse valve is opened, and compressed air is blown into the air inlet pipe 3 through the mounting tube 1. The compressed gas passes through the rotating air pipe 1. 4. The compressed gas enters the jet pipe 15 and is ejected from the jet pipe 15. The rapidly ejected compressed gas causes the jet pipe 15 to drive the rotating air pipe 14 to rotate, blowing and cleaning the outside. At the same time, the internal air pressure of the equipment decreases, and the external pressure causes the beater 11 to be pressed down quickly to beat and clean the filter barrel 21. The rotating jet pipe 15 slides in the slide groove 19. The sliding jet pipe 15 squeezes and contracts the contact 16, pushing the end soft block 18 to extend. The extended soft block 18 impacts and beats the filter barrel 21, further cleaning the dust that is difficult to blow off by the gas.

[0040] When it is necessary to replace the air intake pipe 3 and the bottom jet assembly, simply move the air intake pipe 3 upwards. The slider 4 will squeeze and retract the clamp 6. The upward-moving air intake pipe 3 will drive the slider 4 to continue moving upwards. When the slider 4 exceeds the clamp 6, the clamp 6 will spring back, causing the slider 4 to move upwards. The upward-moving slider 4 will engage with the groove 5 at the bottom of the fixed pipe 1. Then, move the air intake pipe 3 downwards. The air intake pipe 3 will drive the slider 4 downwards to squeeze and retract the clamp 6, allowing the air intake pipe 3 and the bottom jet assembly to be removed, achieving quick disassembly.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
