Description

Technical Field

[0001] The utility model relates to the technical field of gas compressors, in particular to an air filtering device for a gas compressor. Background Technique

[0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. It is commonly used to provide gas power for pneumatic tools and is also commonly used to compress media such as oxygen, hydrogen, ammonia, natural gas, coke oven gas, and inert gas in industries such as petrochemical, drilling, and metallurgy. According to different exhaust pressures, compressors can be divided into low-pressure compressors, medium-pressure compressors, high-pressure compressors, and ultra-high-pressure compressors, etc. Low-pressure compressors are single-stage, while medium-pressure, high-pressure, and ultra-high-pressure compressors are multi-stage, with a maximum number of stages up to eight. According to the different compression media, general compressors can also be called air compressors, oxygen compressors, nitrogen compressors, hydrogen compressors, etc. When a gas compressor sucks in and compresses external air, since the external gas contains impurities, filtration is required during compression, and thus an air filtering device is needed.

[0003] In a patent document with the publication number of CN220015434U, an air filtering device for a gas compressor is disclosed, which includes a gas compressor body and a gas compressor inlet pipe. The gas compressor inlet pipe is fixedly installed at the outer end of the gas compressor body. An assembly connection pipe is arranged at the outer end of the gas compressor inlet pipe. A filtering tank body is arranged at the outer end of the assembly connection pipe. A rear side uniform flow through-hole plate is arranged inside the filtering tank body. An intermediate filtering core cotton is arranged on the filtering tank body outside the rear side uniform flow through-hole plate. A front side uniform flow through-hole plate is arranged on the filtering tank body outside the intermediate filtering core cotton. An external connection pipe is arranged at the outer end of the filtering tank body. In the process of implementing this technical solution, the inventor found that at least the following problems exist in the prior art:

[0004] When the above device is actually used, by arranging uniform flow through-hole plates on both sides of the filtering core cotton, air is evenly dispersed through a number of small holes inside the uniform flow through-hole plates for input filtration. However, these small through-holes are easily blocked by dust and impurities, affecting the filtering effect of the filtering core cotton and the air intake efficiency of the compressor, and it is not convenient to disassemble and clean it, so it is relatively inconvenient to use.

[0005] It should be noted that the information disclosed in this background technical part is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.

[0027] Please refer to Figures 1 - 3 , an air filtering device for a gas compressor, including a gas compressor body 1.

[0028] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, one end of the gas compressor body 1 is connected to an intake pipe 2. One end of the intake pipe 2 is flange-connected to a tank body 3. An anti-blowing assembly 4 is arranged inside the tank body 3. A blower 5 is arranged on one side of the tank body 3. One end of the blower 5 is connected to a filter box 6 through a pipe. Three air suction pipes 7 are connected to one side of the filter box 6 through pipes. One end of the air suction pipe 7 is connected to the outside of the tank body 3. A connecting pipe 8 is connected to the top of the tank body 3. A first fixing ring 9 and a second fixing ring 10 are respectively arranged inside the tank body 3. A filter plate 11 and a filter net 12 are respectively arranged inside the first fixing ring 9 and the second fixing ring 10.

[0029] The anti-blowing assembly 4 includes a blowing pipe 41 arranged on the top of the tank body 3. The bottom end of the blowing pipe 41 is connected to a blowing disc 42. A number of jet nozzles 43 are connected to one side of the blowing pipe 41. A through hole 44 is opened in the middle of the blowing disc 42. One end of the blower 5 is connected to one end of the blowing pipe 41.

[0030] It should be noted that: the intake end of the gas compressor body 1 is connected to the tank body 3 through the intake pipe 2. After the gas compressor body 1 operates, external air first enters the tank body 3 through the connecting pipe 8. The air entering the tank body 3 is filtered by the filter plate 11 and the filter net 12 inside the first fixing ring 9 and the second fixing ring 10, making the air cleaner. The purified air enters the gas compressor body 1 through the through hole 44 and the intake pipe 2. After long-term use, a large amount of dust and impurities will be adsorbed on the filter plate 11 and the filter net 12. At this time, the blower 5 is used to send air into the blowing pipe 41. The gas is discharged through a number of jet nozzles 43 on one side of the blowing disc 42, blowing air onto the filter plate 11 and the filter net 12. The dust and impurities are blown off through the anti-blowing effect. Then, the dust and air are sucked into the filter box 6 through the three air suction pipes 7 for cyclic anti-blowing treatment to ensure the filtering effect of the filter plate 11 and the filter net 12.

[0031] A rotating rod 13 is rotatably arranged on the inner wall of the tank body 3. The outer sides of the rotating rod 13 are rotatably matched with the inner walls of the filter plate 11 and the filter net 12.

[0032] A scraping plate 14 is fixedly connected to the outer side of the rotating rod 13. A cleaning brush 15 is arranged on one side of the scraping plate 14.

[0033] The scraping plate 14 is located on both sides of the first fixing ring 9 and the second fixing ring 10. One side of the cleaning brush 15 is attached to the filter plate 11 and the filter net 12 for installation.

[0034] A motor 16 is fixedly connected to one side of the tank body 3. The output end of the motor 16 is fixedly matched with one end of the rotating rod 13.

[0035] A fixing seat 17 is bolted to the bottom of the tank body 3.

[0036] It should be noted that: the rotating rod 13 is driven to rotate by the motor 16. The rotating rod 13 rotates on the inner walls of the tank body 3, the filter plate 11 and the filter net 12, and then drives the scraping plate 14 to rotate on both sides of the filter plate 11 and the filter net 12, so that the cleaning brush 15 on one side of the scraping plate 14 cleans the filter plate 11 and the filter net 12, improving the cleaning effect on dust and the back-blowing efficiency. The tank body 3 is supported and fixed by the fixing seat 17, improving the stability of the tank body 3.

[0037] The working principle of an air filtration device for a gas compressor provided by the present utility model is as follows:

[0038] During use, the intake end of the gas compressor body 1 is connected to the tank body 3 through the intake pipe 2. After the gas compressor body 1 operates, external air first enters the tank body 3 through the connecting pipe 8, and is filtered by the filter plate 11 and the filter net 12 inside the first fixing ring 9 and the second fixing ring 10, making the air cleaner. The purified air enters the gas compressor body 1 through the through holes 44 and the intake pipe 2. After long-term use, a large amount of dust and impurities will be adsorbed on the filter plate 11 and the filter net 12. At this time, the blower 5 sends air into the air blowing pipe 41, and the gas is discharged through a plurality of air jet nozzles 43 on one side of the air blowing disc 42, blowing air onto the filter plate 11 and the filter net 12, and blowing off the dust and impurities through the back-blowing effect. Then, the dust and air are sucked into the filter box 6 through the three suction pipes 7 for cyclic back-blowing treatment to ensure the filtering effect of the filter plate 11 and the filter net 12.

[0039] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
