Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a dust baffle for a screw air compressor housing. Background Art

[0002] An air compressor is a device used to compress gas. Its construction is similar to that of a water pump. Most air compressors use a reciprocating piston, rotating vanes, or a rotating screw. To prevent dust from entering the compressor, protective measures are required to prevent it from affecting normal operation. Dust covering the compressor can also affect heat dissipation.

[0003] In this regard, the Chinese utility model patent with authorization announcement number CN220059861U discloses a shock-absorbing and dust-proof air compressor including a base, an outer cover fixedly mounted on the top of the base, a door rotatably mounted on the outside of the outer cover, a shock-absorbing pad 1 fixedly mounted on the top of the base, a plurality of fixers fixedly mounted on the outside of the outer cover, and a dust-proof net fixedly mounted on the outside of the fixer. The shock-absorbing and dust-proof air compressor is provided with shock-absorbing pads 1 and 2 to reduce shock on both sides and the bottom of the air compressor body. The dust-proof net prevents dust from entering the inside of the outer cover. Bolt 2 prevents dust from affecting the dust-proof effect when there is a lot of dust. At the same time, the dust-proof net can be quickly replaced. The inside of the outer cover of the shock-absorbing and dust-proof air compressor is made of sound-absorbing foam material, which can absorb noise and reduce the reflection of sound waves. The heat dissipation net has a strong practicality.

[0004] In order to prevent dust from entering the air compressor housing through the heat dissipation port, a dust screen is generally used for protection. However, the dust screen needs to be cleaned after a period of use. During the cleaning process, the heat dissipation port lacks protection, and dust can easily enter the air compressor housing through this port. To this end, we propose a dust baffle for the screw air compressor housing to solve the above problem. Utility Model Content
