Screw type air compressor with cooling and dust removing functions

Abstract

The invention discloses a screw type air compressor with the cooling and dust removing functions, which comprises a machine body. An air compression cavity is formed in the machine body; mutually symmetrical connecting cavities are formed on the left side and the right side of the air compression cavity; a belt wheel cavity extending upwards is formed between the connecting cavity on the left side and the air compression cavity; and adapter coupling blocks which are symmetrically front and back are fixedly arranged on the wall faces of the sides, away from the air compression cavity, of the connecting cavities. According to the invention, by carrying out water cooling treatment on a female screw blade and a male screw blade which rotate at a high speed, the problem of equipment temperature rising caused by continuous air compression is effectively solved; meanwhile, the device can avoid leakage of cooling water; when the device is in a running state, external air can be filtered, and external dust is effectively prevented from entering the air compression cavity so as to prolong the service life of the device; and meanwhile, the device can clean the filtered dust in time, so that the working efficiency of the device is improved.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to a screw air compressor with cooling and dust removal functions. Background technique [0002] Existing air compressors are divided into several categories: reciprocating piston type, rotary vane type, rotary screw type and centrifugal type. Piston type compressor and centrifugal type compressor have high speed, which is easy to cause wear between parts and components. The progress requirements of the components are high. The rotary screw compressor has a simple structure and stable operation, but there are certain defects. The existing screw compressor has poor heat dissipation effect and lacks air filtration function, which may easily cause dust in the outside air to enter the compressed air. cavity, which in turn causes wear between parts and shortens the service life of the equipment. A screw air compressor with a cooling and dust removal function described in the present invent...
