Pre-separation system for positive-displacement air compressor

Abstract

The invention discloses a pre-separation system for a positive-displacement air compressor. The pre-separation system for the positive-displacement air compressor comprises a shell. An exhaust pipe close to the closed end is installed at the top of the shell. A partition plate which is parallel to the horizontal plane is arranged at the closed end of the shell. The partition plate extends from the closed end of the shell to the open end of the shell and divides the internal space of the shell into an air filtering chamber and a sand collecting chamber. A sand collecting chamber cover matched with the sand collecting chamber is arranged at the end, located at the open end of the shell, of the sand collecting chamber. Channel plates perpendicular to the partition plate are arranged on the partition plate. A plurality of channels are formed in each channel plate. Sand discharging holes are formed in the partition plate. The sand content of air filtered by the channel plates is greatly reduced, and an air filter of the air compressor is prevented from being damaged by a small amount of sand, and an operator does not need to dismount and clean the air filter frequently; and the space of the sand collecting chamber is large enough to contain sand, the air exhaust pipe is disconnected with an air inlet of the air compressor after the sand in the sand collecting chamber is accumulated to a certain degree, the sand collecting chamber cover is opened, and then the sand is discharged.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to a pre-separation system for volumetric air compressors. Background technique [0002] Air compressors, also known as air compressors, are general-purpose machinery in modern industries and the core equipment of pneumatic systems. Air compressors convert the mechanical energy of electric motors or diesel engines into gas pressure energy, and increase the gas pressure or transport gas by compressing the gas. Purpose. Air compressors are widely used in steel, electric power, metallurgy, petroleum, mining, automobile industry, aerospace and infrastructure and other fields. [0003] There are many types of air compressors, mainly divided into two categories: positive displacement air compressors and speed air compressors. Among them, positive displacement air compressors include rotary air compressors, which have rotary pistons, and mainly include screw air compressors, sliding vane c...
