Screw-type air compressor with external air intake and dust filtering functions

Abstract

The invention discloses a screw-type air compressor with external air intake and dust filtering functions. The air compressor comprises a compressor body, wherein the compressor body comprises an air intake system. The air compressor is characterized in that the air intake system comprises an independent air intake channel which is composed of a rectangular box; the air intake channel box is isolated from an internal heat source of the compressor; the start end of the air intake channel is an air inlet; the air inlet is arranged on a door plate of the compressor; a noise reducer and a partition board are arranged behind the air inlet in sequence; the surface of the partition board is provided with sound absorption foam; and the tail end of the air intake channel is connected with an air filter of the air compressor. Through the air intake system provided by the invention, the air sucked by the machine is completely cool air, and a filter screen on the door plate has the function of electrostatic precipatation; and the partition board in the air intake channel box can block part of sucked dust, thus air entering in the compressor is cleaner, and simultaneously the sound absorption foam on the partition board can absorb the air intake noise.

Description

technical field [0001] The invention relates to the field of air intake equipment for screw air compressors, in particular to a screw air compressor with external air intake and dust filtering functions. Background technique [0002] Screw air compressors (air compressors) drive compression components at the optimum speed for the application through an efficient transmission system. Screw air compressors are widely used due to their advantages of high stability, high efficiency, low vibration and low noise. [0003] However, the air intake systems of screw air compressors currently on the market have the following two defects: First, most of them use internal air suction, and the air sucked is hot air, which will cause the air volume produced by the unit to be insufficient. It will also affect the service life of the air compressor; the second is that most of the current air compressors need to install expensive high-dust filters in order to work in an environment with hars...
