Description

Technical Field

[0001] The utility model belongs to the technical field of screw air compressors, and more specifically, particularly relates to a screw air compressor used for anodizing. Background Art

[0002] When anodizing metal products, it is generally necessary to put the metal products into a cleaning tank for degreasing and degreasing. To ensure the cleaning effect of the metal products, it is generally necessary to connect an air compressor to the bottom of the cleaning tank. The air compressor injects compressed air into the cleaning tank to make the cleaning liquid in the tank roll and fully contact the metal parts, so as to achieve the purpose of degreasing and degreasing the metal parts. Existing air compressors mostly use a screw structure. Screw air compressors generally perform gas pressurization through the mechanical movement of the master and slave screws. To ensure the stable operation of the screw air compressor, it is generally necessary to set a lubrication system for the screw air compressor. By injecting lubricating oil into the screw air compressor, part of the heat of the screw air compressor is taken away through the circulation of the lubricating oil, and at the same time, it plays a lubricating function for the master and slave screws.

[0003] The existing application number is: CN201420571959.6. The utility model proposes a screw air compressor, including a motor, a compression host, an air inlet pipe, an air outlet pipe and a box body, wherein the motor and the compression host are installed inside the box body, the motor drives the compression host, the air inlet pipe is connected to the air inlet of the compression host, and it also includes a radiator, the air outlet of the compression host is connected to the air inlet of the radiator, and the air outlet of the radiator is connected to the air outlet pipe, the compression host includes a compressor shell and a bearing seat, the compressor shell and the bearing seat are an integrated structure, the inner wall of the compressor shell and the inner wall of the bearing seat intersect at a right angle, the compressor shell is provided with a mutually meshing active screw rotor and a driven screw rotor, and the bearing seat is provided with a first bearing supporting the active screw rotor and a second bearing supporting the driven screw rotor. The utility model also improves work efficiency, and at the same time reduces noise, prolongs the service life of the host, and improves the reliability of the equipment.

[0004] Based on the above, in order to ensure the cleanliness of the existing lubricating oil during its circulation process, it is generally necessary to set a filter for the lubricating oil. However, due to the wear between the master and slave screws, the worn iron filings will enter the filter along with the lubricating oil and be filtered. The iron filings accumulate on the surface of the filter for a long time, which can easily affect the passage of the lubricating oil through the filter, resulting in insufficient oil intake of the screw air compressor, causing the screw air compressor to heat up, and affecting the normal operation of the screw air compressor.

[0052] The oil filter box 3 is arranged on the front right side of the air compressor body 1, and the lower end of the oil filter box 3 is externally connected to an oil pump;

[0057] The filter connection mechanism is arranged inside the oil filter box 3 .

[0058] The filter connection mechanism includes: a first connection member 101, a second connection member 102, a connection spring 103, a cleaning connecting groove 104, a cleaning collection box 105, a cleaning rubber block 106 and a collection guide plate 107;

[0059] The first connecting member 101 is fixedly connected to the inner upper end of the oil filter box 3, and the first connecting member 101 is provided with a slide groove structure;

[0060] The second connecting member 102 is slidably connected to the inside of the slide groove of the first connecting member 101, and the lower end of the second connecting member 102 is fixedly connected to the upper end of the filtering and scraping net 7;

[0061] The connecting spring 103 is fixedly connected to the upper end of the slide groove of the first connecting member 101, and the lower end of the connecting spring 103 is fixedly connected to the second connecting member 102;

[0062] The cleaning connecting groove 104 is a circular groove structure, and the cleaning connecting groove 104 is opened at the middle position of the outer circumference of the oil filter box 3;
