Description

Technical Field

[0001] This utility model relates to the field of chemical pulse dust removal technology, and in particular to a multi-stage filtration chemical pulse dust removal device. Background Technology

[0002] In industries such as chemical engineering, metallurgy, mining, and machinery manufacturing, large amounts of dust are frequently generated during production. Dust not only pollutes the environment but can also harm human health, especially the respiratory system. Excessive dust can also lead to equipment corrosion, blockage, and malfunctions, affecting production efficiency. Therefore, effective dust control measures must be taken.

[0003] For example, Chinese utility model patent application number 202021057744.4 discloses a multi-stage pulse dust collector. Multiple pulse dust collector bodies are connected end to end by connecting pipes. A filter device is provided between the air inlet and outlet of the pulse dust collector body. The filter device includes a mounting plate. Multiple filter cylinders are arranged on the side of the mounting plate near the air inlet. The mesh size of the filter cylinders in the pulse dust collector body gradually increases from the air inlet to the air outlet. A dust hopper is provided on the lower surface of the pulse dust collector body. A dust removal and ash discharge valve is installed at the bottom opening of the dust hopper. In this utility model, through multiple filter cylinders, a telescopic device drives an air disc to move linearly inside the filter cylinder. The gas ejected from the air nozzles opened on the side wall of the air disc blows the gas from the inside of the filter cylinder to the outside, blowing away the dust attached to the filter cylinder in the opposite direction.

[0004] Although the above solutions can achieve multi-stage filtration and dust removal, they have problems such as high cost and large footprint. In addition, the filter cartridges of traditional pulse dust collectors are generally installed and maintained by workers. Moreover, there are often multiple filter cartridges on the dust collector, and workers need to remove and inspect them one by one each time, which is very time-consuming and troublesome. Reinstallation after each maintenance is also time-consuming and labor-intensive. Therefore, a multi-stage filtration chemical pulse dust removal device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage filtration chemical pulse dust removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage filtration chemical pulse dust collector, comprising a base plate, a pulse dust collector body and two support seats fixedly installed on the top of the base plate, a plurality of mounting ports sequentially opened on the top of the pulse dust collector body, a filter cartridge slidably connected inside the mounting port, a filling component and a mounting component being provided inside the filter cartridge, a fixing block being provided on the top of the mounting component, a grid frame being fixedly connected to the top of the fixing block, a threaded block being fixedly connected to the top of the grid frame, a gear frame being fixedly connected to the top of each of the two support seats, a driving component capable of driving the threaded block to move up and down being provided on one side of the gear frame, and a jetting component and an induced draft component being provided on the top of the base plate.

[0007] The filter cartridges are in at least three groups, with the filter holes on each group arranged sequentially from large to small starting from the dust inlet pipe. By setting a filling component, the filtration and dust removal effect can be improved. By setting an installation component, the filter cartridges can be easily installed. By setting a drive component, the control device can automatically lift and lower the filter cartridges, making it easy to lift the filter cartridges from the pulse dust collector body. By setting a jet cleaning component, compressed gas can be sprayed into the filter cartridges to keep them clean and ensure their filtration effect.

[0008] As a further description of the above technical solution:

[0010] The filler materials, arranged in order of filter cartridge pore size, consist of coarse filter cloth, glass fiber, activated carbon, and finally, non-woven fabric in the smallest pore size filter cartridge. The primary filter cartridge has a larger pore size and uses coarse filter cloth to reduce the amount of pollutants entering the middle layer and protect the middle and fine filtration layers. The middle filter cartridge has a smaller pore size and uses fiber materials to further remove residual medium-sized particles, while also adding an activated carbon layer to remove harmful gases. The final filter cartridge has the smallest pore size, which can effectively remove micron-sized particles and ensure that emissions meet environmental requirements.

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

[0012] The mounting assembly includes a threaded groove formed in the inner wall of the filter cartridge, and a threaded disc is threadedly connected to the threaded groove.

[0013] The top of the threaded disc is fixedly connected to the bottom of the fixing block. The filter cartridge can be easily fixed by the threaded connection, making it easy to disassemble and replace.

[0014] As a further description of the above technical solution:

[0015] The drive assembly includes a drive motor fixedly mounted on one side of one of the gear frames. The output end of the drive motor rotates through the interior of both gear frames and is fixedly connected to a synchronous shaft. Worms are fixedly connected to the outer wall of the synchronous shaft and inside both gear frames.

[0016] One end of the synchronous shaft is rotatably connected to the inner wall of another gear frame. By setting the synchronous shaft, it can be ensured that the two worms rotate simultaneously, and that the threaded rods rotate synchronously.

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

[0018] Both worm gears have worm wheels meshing with their outer walls. A connecting shaft is fixedly connected inside the worm wheel. The top end of the connecting shaft extends through to the outside of the gear frame and is fixedly connected to a threaded rod. The top ends of both threaded rods are rotatably connected to a baffle. The outer walls of both threaded rods are threadedly connected to a threaded block.

[0019] By using a worm gear and worm shaft, the self-locking feature is utilized to prevent the threaded block from accidentally falling off, ensuring safe use.

[0020] As a further description of the above technical solution:

[0021] The blowing assembly includes an air compressor fixedly installed on the top of the base plate. The air outlet of the air compressor is fixedly connected to a triangular tube. Three solenoid valves are fitted on the outer wall of the triangular tube. Several blowing pipes are fixedly connected to the top of the triangular tube.

[0022] By setting up an air compressor, compressed air can be generated. When the dust accumulation on the surface of the filter cartridge reaches a certain value, the dust accumulation on the surface of the filter cartridge can be effectively shaken off by compressed air and pulse jet cleaning technology, restoring the filtration efficiency.

[0023] As a further description of the above technical solution:

[0024] The air intake assembly includes an air intake duct fixedly installed on the top of the base plate, an air intake pipe fixedly connected to the outer wall of the air intake duct, and an air intake fan fixedly installed inside the air intake duct.

[0028] By setting up a discharge hopper, dust particles of different sizes can be discharged.

[0029] This utility model has the following beneficial effects:

[0030] 1. Compared with existing technologies, this multi-stage filtration chemical pulse dust collector, through the coordinated use of filter cartridges, grid frames, threaded blocks, and drive components, makes the disassembly, cleaning, and replacement of filter cartridges more convenient and efficient. Workers only need to rotate the filter cartridges to complete the disassembly, replacement of filling materials, and reinstallation, which improves maintenance efficiency, reduces the complexity of manual operation, and saves personnel time and labor intensity in disassembling and replacing filter cartridges. It is especially convenient when replacing multiple filter cartridges, greatly improving work efficiency.

[0031] 2. Compared with existing technologies, this multi-stage filtration chemical pulse dust collector, through the coordinated use of filling components, mounting components, pulse-jet components and induced draft components, can achieve high-efficiency filtration of dust-laden gas through a multi-stage filter cartridge system.

[0040] 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.

[0041] Reference Figure 1-6 This utility model provides a multi-stage filtration chemical pulse dust collector, comprising a base plate 1, a pulse dust collector body 2 and two support seats 3 fixedly mounted on the top of the base plate 1, a plurality of mounting ports 4 sequentially opened on the top of the pulse dust collector body 2, filter cartridges 5 slidably connected inside the mounting ports 4, a filling component and a mounting component arranged inside the filter cartridges 5, a fixing block 6 arranged on the top of the mounting component, a grid frame 7 fixedly connected to the top of the fixing block 6, a threaded block 8 fixedly connected to the top of the grid frame 7, a gear frame 9 fixedly connected to the top of each of the two support seats 3, a driving component capable of driving the threaded block 8 to move up and down arranged on one side of the gear frame 9, a jet blowing component and an induced draft component arranged on the top of the base plate 1, and at least three sets of filter cartridges 5, the filter holes on each set of filter cartridges 5 arranged sequentially from large to small starting from the dust inlet pipe 28, by setting the filling component, can... To improve filtration and dust removal efficiency, the installation components facilitate the installation of filter cartridge 5. The drive components enable automatic lifting and lowering of the control device, allowing filter cartridge 5 to be easily lifted from the pulse dust collector body 2. The jet cleaning components spray compressed gas into the filter cartridge 5, keeping it clean and ensuring its filtration effect. The coordinated use of the filter cartridge 5, the grid frame 7, the threaded block 8, and the drive components makes the disassembly, cleaning, and replacement of filter cartridge 5 more convenient and efficient. Workers can simply rotate the filter cartridge 5 to disassemble it, replace the filler 11, and reinstall it, improving maintenance efficiency, reducing the complexity of manual operation, and saving time and labor intensity when disassembling and replacing filter cartridge 5. This is especially convenient when replacing multiple filter cartridges 5, greatly improving work efficiency.

[0042] The filling assembly includes a filling port 10 at the top of the filter cartridge 5. Filling material 11 is movably installed inside the filling port 10. The filling material 11, in order of the filter cartridge 5's pore size, consists of coarse filter cloth, glass fiber, activated carbon, and finally, non-woven fabric inside the smallest pore size filter cartridge 5. The primary filter cartridge 5 has a larger pore size and uses coarse filter cloth to reduce the amount of pollutants entering the middle layer and protect the middle and fine filtration layers. The middle filter cartridge 5 has a smaller pore size and uses fiber material to further remove residual medium-sized particles. An activated carbon layer is also added to remove harmful gases. The final filter cartridge 5 has the smallest pore size, effectively removing micron-sized particles to ensure emissions meet environmental requirements. The installation assembly includes a threaded groove 12 on the inner wall of the filter cartridge 5. A threaded disc 13 is threaded onto the threaded groove 12. The top of the threaded disc 13 is fixedly connected to the bottom of the fixing block 6. This threaded connection allows for easy fixation of the filter cartridge 5, facilitating disassembly and replacement.

[0043] The drive assembly includes a drive motor 14 fixedly mounted on one side of one of the gear frames 9. The output end of the drive motor 14 rotatably extends into the interior of both gear frames 9 and is fixedly connected to a synchronous shaft 15. Worms 16 are fixedly connected to the outer wall of the synchronous shaft 15 and inside both gear frames 9. One end of the synchronous shaft 15 is rotatably connected to the inner wall of the other gear frame 9. By setting the synchronous shaft 15, it can be ensured that the two worms 16 rotate simultaneously, and that the threaded rod 19 rotates synchronously. Worm wheels 17 are meshed with the outer walls of both worms 16. A connecting shaft 18 is fixedly connected inside the worm wheel 17. The top end of the connecting shaft 18 extends to the outside of the gear frame 9 and is fixedly connected to the threaded rod 19. The top ends of both threaded rods 19 are rotatably connected to a baffle 20. The outer walls of both threaded rods 19 are threadedly connected to the threaded block 8. By setting the worm wheel 17 and worm 16, the self-locking feature can be used to prevent the threaded block 8 from accidentally falling off, ensuring safe use.

[0044] The pulse jet cleaning assembly includes an air compressor 21 fixedly installed on the top of the base plate 1. The air compressor 21 has a fixed connection to a U-shaped pipe 22 at its outlet. Three solenoid valves 23 are fitted onto the outer wall of the U-shaped pipe 22. Several pulse jet pipes 24 are fixedly connected to the top of the U-shaped pipe 22. By installing the air compressor 21, compressed air can be generated. When the dust accumulation on the surface of the filter cartridge 5 reaches a certain value, the dust accumulation on the surface of the filter cartridge 5 can be effectively shaken off by compressed air and pulse jet cleaning technology, restoring the filtration efficiency. The air intake assembly includes components fixedly installed on the base plate 1. The top of the plate 1 has an exhaust duct 25, and the outer wall of the exhaust duct 25 is fixedly connected to an exhaust pipe 26. An exhaust fan 27 is fixedly installed inside the exhaust duct 25. One end of the exhaust pipe 26 is fixedly connected to the pulse dust collector body 2. By setting the exhaust fan 27, dust-laden gas can be continuously drawn out, thereby ensuring the operation of the dust collector. One side of the pulse dust collector body 2 is fixedly connected to a dust inlet pipe 28, and the bottom of the pulse dust collector body 2 is fixedly connected to three discharge hoppers 29. By setting the discharge hoppers 29, dust of different particle sizes can be discharged.

[0045] Working principle: First, when using the device, the gas to be dusted is connected to the dust inlet pipe 28. Then, the induced draft fan 27 is started, which generates suction on the pulse dust collector body 2, drawing the dust-laden gas into it. The gas is filtered through the multi-stage filter cartridges 5 inside the pulse dust collector body 2. The blocked dust is discharged sequentially from the discharge hoppers 29 below the filter cartridges 5 with different aperture sizes. The filtered air is drawn into the induced draft pipe 26 by the induced draft fan 27 and finally discharged from the top of the induced draft pipe 25, thus achieving the purpose of multi-stage filtration and better removing dust from the dust-laden gas generated by chemical products. When the dust content on the surface of the multi-stage filter cartridges 5 reaches a certain value or after a period of use, the air compressor 21 can be started to generate compressed air, which is sent into the triangular pipe 22. Through the opening of the solenoid valve 23, the compressed air is sent into the filter cartridges 5, thereby shaking off the accumulated dust on the surface of the filter cartridges 5 through the high-pressure airflow, maintaining filtration efficiency and ensuring long-term use of the dust removal device.

[0046] When filter cartridge 5 needs replacement or maintenance, the drive motor 14 can be started. The output end rotates, driving the synchronous shaft 15 to rotate, which in turn drives the two worm gears 16 to rotate, causing the meshing worm wheel 17 to rotate. Simultaneously, the connecting shaft 18 drives the threaded rod 19 to rotate, thus moving the threaded block 8. The movement of the threaded rod 19, in turn, drives the grid frame 7 to move, causing the fixing block 6 to move the threaded disc 13. This lifts the filter cartridge 5, which is fixed by the threaded connection, thus removing all filter cartridges 5 from the pulse dust collector body 2 at once, facilitating replacement and maintenance by the staff. After removal, the staff only needs to rotate the filter cartridge 5, at which point the threaded groove 12 on the inner wall of the filter cartridge 5 engages with the threaded groove 12. Once the threaded disc 13 is released from its threaded fastening, the filter cartridge 5 can be easily removed. Then, the staff can replace the internal fillers 11, such as the coarse filter cloth in the large-pore filter cartridge 5, the glass fiber and activated carbon in the medium-pore filter cartridge 5, and finally the non-woven fabric in the small-pore filter cartridge 5. After maintenance, simply rotate the filter cartridge 5 in the reverse direction to secure the threaded groove 12 to the threaded disc 13, easily completing the installation. Then, start the drive motor 14 to rotate in the reverse direction, allowing the filter cartridge 5 to be placed inside the pulse dust collector body 2, with the bottom of the filter cartridge 5 resting on the blowpipe 24. This completes the maintenance and installation of the filter cartridge 5, making it convenient for staff and reducing the hassle of disassembling and maintaining each cartridge individually from the pulse dust collector body 2.

[0047] 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.
