Pre-sand discharge structure of rotary air compressor

Abstract

The invention discloses a pre-sand-discharging structure for a rotor-type air compressor. The pre-sand-discharging structure comprises a shell, an air exhaust pipe, a rinsing pipe, a first grating, a second grating and a third grating, wherein a separation plate is arranged on the closed end of the shell; the separation plate extends to an open end from the closed end of the shell, and divides the space in the shell into an air filter chamber and a sand collection chamber; the end, located at the open end of the shell, of the sand collection chamber is provided with a sand collection chamber cover matched with the end; a passage plate vertical to the separation plate is arranged above the separation plate; a plurality of passages are arranged on the passage plate; and a sand discharging hole is formed in the separation plate. The sand content in air filtered by the passage plate is greatly lowered; the air filter of the air compressor cannot be damaged by a small amount of sand; operation personnel do not need to disassemble and clean the air filter frequently; the sand collection chamber has enough space to contain sand; and when sand in the sand collection chamber accumulates to a certain degree, the air exhaust pipe is disconnected from the air inlet of the air compressor, and the sand chamber cover is opened, so that the sand can be discharged.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to a pre-sand discharge structure of a rotor type air compressor. 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...
