Description

Technical Field

[0001] The utility model relates to the technical field of air compressor dust prevention, in particular to a dust-proof filtering device for the air inlet of an air compressor. Background Technique

[0002] An air compressor is a device used to compress gas. The air compressor is similar in structure to a water pump. Most air compressors are reciprocating pistons, rotary vanes or rotary screws. The use environment of an air compressor generally requires clean air. In a relatively poor environment, it is easy for the air compressor to inhale a large amount of dirty air, which will cause the internal components of the air compressor to be easily damaged and affect the service life. Therefore, the operating environment of the air compressor should meet the requirement of clean air.

[0003] However, in the current actual situation, most air compressors are used in industrial workshops, and the use environment is relatively poor. Generally, the air compressor needs to be placed in a corner of the factory, where the dust is relatively large. During long-term use, it will cause damage to the inside of the air compressor. Therefore, a dust-proof filtering device for the air inlet of an air compressor is needed to protect the air compressor. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a dust-proof filtering device for the air inlet of an air compressor to solve the technical problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A dust-proof filtering device for the air inlet of an air compressor, including an air storage tank and a compressor. One end of the compressor is fixedly installed with a dust removal box, and one end of the dust removal box is fixedly installed with an air guide pipe. Air cavities are opened at both ends of the dust removal box. One end of the air cavity is movably installed with a piston, and one end of the piston is fixedly installed with a spring. One side of the piston is fixedly installed with a connecting frame, and one end of the connecting frame is fixedly installed with an electrostatic net. Guide grooves matching with the connecting frame are opened at both ends of the dust removal box, and scraping plates matching with the electrostatic net are fixedly installed at both ends of the dust removal box.

[0006] By adopting the above technical solution, the electrostatic net is driven by an electrostatic generator, so that the surface of the electrostatic net carries static electricity. The dust that is not filtered in the air is captured and adsorbed by the electrostatic force through the activated carbon plate of the air filter, thereby increasing the filtering effect on the air and making the inhaled air reach the clean degree required for the use of the air compressor.

[0007] The utility model is further set as follows: One end of the dust removal box is fixedly installed with an air filter, and a plurality of air inlet holes are opened at one end of the air filter. A plurality of activated carbon plates are fixedly installed on one side inside the air filter.

[0008] By adopting the above technical solution, by installing an activated carbon plate, the activated carbon plate can filter impurities in the air. The activated carbon plate has a strong adsorption capacity and can adsorb odor substances and organic molecules that cause color changes in the air, improving the air odor and enhancing the air cleanliness.

[0009] The present utility model is further configured such that the gas storage tank and the compressor are connected through a conveying pipe assembly, and a rotary valve is movably installed at one end of the conveying pipe assembly, and a spherical limit valve is fixedly installed at one end of the rotary valve.

[0010] By adopting the above technical solution, by installing the conveying pipe assembly, the conveying pipe assembly has good sealing performance and stability, can effectively prevent leakage during the transportation of compressed air, has a relatively high flexibility in use, and improves the safety of the overall transportation of the device.

[0011] The present utility model is further configured such that a pressure gauge is fixedly installed at one end of the gas storage tank, and a compressed air discharge port is fixedly installed at one end of the bottom of the gas storage tank. A support frame is fixedly installed at one end of the gas storage tank, and a pressure relief port is provided at one end of the gas storage tank.

[0012] By adopting the above technical solution, by installing the support frame, the gas storage tank obtains better supporting force and is more stable during the operation and use of the device.

[0013] The present utility model is further configured such that a dust collection box is fixedly installed at one end of the dust removal box, and an electrostatic generator is fixedly installed at one end of the connecting frame.

[0014] By adopting the above technical solution, by installing the dust collection box, the dust collection box is easy to disassemble and clean. The staff can take it out and clean it at any time, saving the trouble of frequently cleaning the inside of the equipment.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] 1. The present utility model is provided with an activated carbon plate, an electrostatic net, an electrostatic generator, etc. The activated carbon plate preliminarily filters larger dust particles in the air inhaled into the air compressor, and the electrostatic generator drives the electrostatic net, making the surface of the electrostatic net carry static electricity. The electrostatic force captures and adsorbs the dust that has not been filtered in the air filtered by the activated carbon plate in the air filter, thereby increasing the filtering effect on the air and making the inhaled air reach the air cleanliness required for the use of the air compressor.

[0017] 2. The utility model is provided with a dust removal box, an electrostatic net, a scraper, a spherical limit valve, etc. By rotating the rotary valve, the spherical limit valve closes and limits the pressure relief port, so that the compressed air discharged from the pressure relief port is conveyed to the air guide pipe through the conveying pipe assembly. At this time, the air guide pipe introduces the compressed air into the air cavity, so that the compressed air pushes the piston, and then the connecting frame starts to drive the electrostatic net to move along the guide groove, so that the electrostatic net and the scraper are displaced relative to each other, and the scraper will contact the surface of the electrostatic net and start to scrape off the dust adsorbed on the surface of the electrostatic net, so that a large amount of dust filtered and adsorbed by the electrostatic net falls into the dust collection box under the action of gravity for unified collection, which is convenient for the staff to clean the dust inside the device, improves the practicability of the device, reduces the dust wear on the device, protects the device components, and improves the service life of the device.

[0024] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0025] An air compressor air inlet dust-proof filtering device, as Figures 1-4As shown in the figure, it includes an air storage tank 1 and a compressor 2. One end of the compressor 2 is fixedly installed with a dust removal box 23. One end of the dust removal box 23 is fixedly installed with a gas guide pipe 12. Both ends of the dust removal box 23 are provided with air cavities 13. One end of the air cavity 13 is movably installed with a piston 14. One end of the piston 14 is fixedly installed with a spring 15. One side of the piston 14 is fixedly installed with a connecting frame 18. One end of the connecting frame 18 is fixedly installed with an electrostatic net 19. Both ends of the dust removal box 23 are provided with guide grooves 17 that cooperate with the connecting frame 18. Both ends of the dust removal box 23 are fixedly installed with scrapers 16 that cooperate with the electrostatic net 19. By rotating the rotary valve 8, the spherical limit valve 22 closes and limits the pressure relief port 7, so that the compressed air discharged from the pressure relief port 7 is transported to the gas guide pipe 12 through the conveying pipe assembly 4. At this time, the gas guide pipe 12 introduces a part of the compressed air into the air cavity 13, and the other part is discharged through the gas guide pipe 12 for pressure relief. The compressed air pushes the piston 14, so that the connecting frame 18 starts to drive the electrostatic net 19 to move along the guide groove 17, so that the electrostatic net 19 and the scraper 16 are displaced relative to each other, and the scraper 16 contacts the surface of the electrostatic net 19. The connecting frame 18 moves repeatedly under the buffering action of the spring 15, so that the dust adsorbed on the surface of the electrostatic net 19 is repeatedly scraped by the scraper 16, so that a large amount of dust filtered and adsorbed by the electrostatic net 19 falls into the dust collection box 21 under the action of gravity for unified collection.

[0026] Please refer to the figure. One end of the dust removal box 23 is fixedly installed with an air filter 5. One end of the air filter 5 is provided with multiple groups of air inlet holes 6. One side inside the air filter 5 is fixedly installed with multiple groups of activated carbon plates 11. By installing the activated carbon plates 11, the activated carbon plates 11 can filter impurities in the air. The activated carbon plates 11 have a strong adsorption capacity and can adsorb odor substances and organic molecules that cause color change in the air, improve the smell of the air, and improve the air cleanliness.

[0027] Please refer to Figure 1 , the air storage tank 1 and the compressor 2 are connected by a conveying pipe assembly 4. One end of the conveying pipe assembly 4 is movably installed with a rotary valve 8. One end of the rotary valve 8 is fixedly installed with a spherical limit valve 22. By installing the conveying pipe assembly 4, the conveying pipe assembly 4 has good sealing performance and stability, can effectively prevent leakage during the transportation of compressed air, has a high degree of flexibility in use, and improves the safety of the overall transportation of the device.

[0028] Please refer to Figure 1 , one end of the air storage tank 1 is fixedly installed with a pressure gauge 10. One end of the bottom of the air storage tank 1 is fixedly installed with a compressed air discharge port 9. One end of the air storage tank 1 is fixedly installed with a support frame 3. One end of the air storage tank 1 is provided with a pressure relief port 7. By installing the support frame 3, the air storage tank 1 obtains better support force and is more stable during the operation and use of the device.

[0029] Please refer to Figure 3, a dust collection box 21 is fixedly installed at one end of the dust removal box 23, and an electrostatic generator 20 is fixedly installed at one end of the connecting frame 18. By installing the dust collection box 21, the dust collection box 21 is easy to disassemble and clean. The staff can take it out and clean it at any time, saving the trouble of frequently cleaning the inside of the equipment.

[0030] The working principle of the present utility model is as follows: When in use, first start the compressor 2, so that the compressor 2 starts to suck air from the air inlet hole 6 through the air filter 5 into the dust removal box 23. At this time, the air filter 5 preliminarily filters larger dust particles in the air sucked into the air compressor through the activated carbon plate 11, and drives the static electricity net 19 through the electrostatic generator 20, so that the surface of the static electricity net 19 carries static electricity, and the dust that is not filtered in the air filtered by the air filter 5 through the activated carbon plate 11 is captured and adsorbed by static electricity, thereby increasing the filtering effect on the air. When dust removal is required inside the air compressor, by rotating the rotary valve 8, the spherical limit valve 22 closes and limits the pressure relief port 7, so that the compressed air discharged from the pressure relief port 7 is conveyed to the air guide pipe 12 through the conveying pipe assembly 4. At this time, the air guide pipe 12 introduces a part of the compressed air into the air cavity 13, and the other part is discharged through the air guide pipe 12 for pressure relief, so that the compressed air pushes the piston 14, thereby causing the connecting frame 18 to drive the static electricity net 19 to move along the guide groove 17, so that the static electricity net 19 and the scraper 16 are displaced relative to each other, and the scraper 16 will contact the surface of the static electricity net 19. The connecting frame 18 moves repeatedly under the buffering action of the spring 15, so that the dust adsorbed on the surface of the static electricity net 19 is scraped repeatedly by the scraper 16, so that a large amount of dust filtered and adsorbed by the static electricity net 19 falls into the dust collection box 21 under the action of gravity for unified collection. After the pressure relief is over, the connecting frame 18 resets under the action of the spring 15, so that the static electricity net 19 resets, thus facilitating the staff to clean the dust inside the device. Finally, rotate the rotary valve 8 so that the spherical limit valve 22 releases the limit on the pressure relief port 7, and that's it.
