[0030] See also Figure 1-4 An energy-saving gas compressor includes an equipment body 1, a mounting base 2, an inner filter unit 3 and an outer filter unit 4. The mounting base 2 includes a barrel 21 arranged on the air inlet pipe of the equipment body 1, and an annularly distributed air inlet is opened on the barrel 21. A scraper 22 is arranged on the air inlet. The inner filter unit 3 is arranged in the barrel 21 and is located at the connection between the barrel 21 and the air inlet pipe of the equipment body 1. The outer filter unit 4 includes a filter element 41 arranged between the inner filter unit 3 and the barrel 21. The filter element 41 is coated on the outside of the inner filter unit 3 and is in contact with the scraper 22. A driving member 42 is arranged between the barrel 21 and the filter element 41.

[0031] Based on the above, the inner filter unit 3 of this embodiment is connected to the cylinder 21, and the combination of the filter element 41 and the cylinder 21 constitutes a fixed filter component on the air inlet channel of the equipment body 1, and the filter element 41 cooperates with the driving element 42 to constitute a filter component that is movable outside the inner filter unit 3 in the cylinder 21. In this way, the inner and outer layers of the filter component are assembled to grade the impurities in the inhaled air, and then the driving element 42 drives the filter element 41 to rotate and replace the filter part on the air inlet of the equipment body 1. In the process of rotation, the scraper 22 cleans the impurities in the part before replacement, and makes the inner filter unit 3 vibrate and shake off the attached impurities, so that the outer filter component of the two-stage filter component can be switched, and the impurities in the filter parts on both sides are cleaned, thereby ensuring the normal air intake of the equipment and saving energy consumption.

[0032] See also Figure 1-4 The cylinder body 21 is composed of a sleeve and a cylinder cover. A socket is provided on the sleeve. A connecting protrusion located on the socket is provided in the sleeve. The air intake pipe of the equipment body 1 passes through the socket and extends into the connecting protrusion. The internal filter unit 3 is provided on the connecting protrusion, and the internal filter unit 3 is connected to the air intake pipe of the equipment body 1.

[0033] The inner filter unit 3 and the outer filter unit 4 are assembled in the above-mentioned cylinder 21. The sleeve of this embodiment is designed with upper and lower openings, and the lower opening is a socket connected to the air intake pipe of the equipment body 1. The cylinder cover is covered on the sleeve through the upper opening and connected by bolts. A tray is provided on the air intake pipe of the equipment body 1. The sleeve is placed on the tray along the air intake pipe through the socket and finally fixed by bolts to complete the connection between the cylinder 21 and the air intake pipe of the equipment body 1.

[0034] For the equipment body 1, the air intake pipe is inserted into the sleeve through the jack, and the connection length between the jack and the air intake pipe is extended by the connecting protrusion, which can increase the connection stability between the sleeve and the air intake pipe. At the same time, a connecting base is formed on the air intake pipe, and a threaded connection design is adopted with the filter cartridge-shaped inner filter unit 3 and the connecting protrusion to fix the inner filter unit 3 above the air intake pipe.

[0035] See also Figure 1-4 The filter element 41 includes a base 411, a filter screen 412 and a top cover 413. The base 411 is arranged in the sleeve, the top cover 413 is arranged between the inner filter unit 3 and the cylinder cover, the filter screen 412 is arranged between the base 411 and the top cover 413, the air inlet is annularly distributed on the sleeve, adjacent scrapers 22 are symmetrically arranged on the same air inlet, the filter screen 412 is located on the outer side of the inner filter unit 3, the filter screen 412 is in contact with the scraper 22, a mounting hole is opened on the cylinder cover, one end of the top cover 413 extends into the mounting hole, and a rotating shaft is arranged on the top cover 413 and the cylinder cover, and the driving member 42 is arranged between the rotating shafts.

[0036] Based on the connecting protrusion at one end of the inner filter unit 3, the filter element 41 is supported between the sleeve and the cylinder cover, the base 411 contacts the inner bottom wall of the sleeve, the top cover 413 is supported between the cylinder cover and the inner filter unit 3, and the top of the inner filter unit 3 is restricted by the top cover 413 and closed, thereby completing the fixed assembly of the inner filter unit 3.

[0037] It should be noted that the inner filter unit 3 is fixed on the air inlet channel of the equipment body 1, and the filter screen 412 of the filter element 41 is located between the sleeve and the inner filter unit 3. When the equipment body 1 is in operation, the inhaled gas first enters from the air inlet of the sleeve, then passes through the filter screen 412, then passes through the inner filter unit 3, and finally enters the equipment body 1 through the air inlet pipe.

[0038] When the driving member 42, which is preferably an electric hydraulic cylinder, is operated, the top cover 413 drives the filter 412 to replace the filtering part on the sleeve air inlet. The sleeve air inlet can be designed as three fan-shaped channels, which are matched with the overall cylindrical design of the filter element 41. The filter 412 is facing the air inlet and contacts the scraper 22. When the filter 412 rotates, the part to be replaced contacts the scraper 22 in the direction of movement to scrape off the attached impurities. At the same time, the cleaned filtering part faces the air inlet to assist the internal filter unit 3 in filtering the air.

[0039] By means of the scrapers 22 arranged on both edges of the air inlet, the filter part before replacement is in a relatively clean state and remains stationary in the sleeve, ready for next use. When the filter is replaced next time, the driving member 42 drives the top cover 413 to reset the filter 412, and the filter part currently in use will also be cleaned by the scrapers 22. In this way, the filter 412 can be switched for multiple uses.

[0040] Based on the rotation of the filter element 41, the inner filter unit 3 is vibrated to shake off impurities. In this embodiment, a plurality of annularly distributed support rods are arranged on the base 411. The support rods are in contact with the connecting protrusions. The rotating base 411 drives the support rods to act on the connecting protrusions, thereby indirectly acting on the inner filter unit 3. At the same time, the rotation of the top cover 413 is also used for the inner filter unit 3, so that the inner filter unit 3 can vibrate and shake off impurities.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
