Axial soundproof air filter for air compressor

Abstract

The invention discloses an axial sound insulation air filter for an air compressor, comprising a barrel-shaped shell, wherein an air outlet hole is formed in middle of an end cover arranged on one end of the barrel-shaped shell and is connected with an air outlet pipe which is arranged on the outer side of the barrel-shaped shell; an air filter core cleading and a positioning ring are arranged on the inner end face of the end cover in the barrel-shaped shell; an axial sound insulation mechanism is sleeved on the positioning ring and comprises a barrel; an air outlet port is formed in the side wall of the other side wall of the barrel; sound insulation plates which are arranged in intervals are distributed along the peripheral direction of the barrel; ventholes are distributed in the sound insulation plates; and the ventholes of the adjacent sound insulation plates are in staggered symmetric distribution; an air inlet is formed in the end cover of the barrel-shaped shell; an air filter core is sleeved on the air filter core cleading and is pressed and sealed by a gland on the other end of the barrel-shaped shell. According to the axial sound insulation air filter, the noises produced when the air compressor works are effectively reduced, air is more efficiently purified, the service life of the air compressor is prolonged, the maintenance frequency of the air compressor is effectively reduced, and energy consumption produced by operation is effectively reduced.

Description

technical field [0001] The invention relates to an air filter, in particular to an axial sound-insulating air filter for an air compressor. Background technique [0002] According to the results of customer feedback and market surveys, it is found that the traditional piston air compressor has the following disadvantages: [0003] (1) The air compressor makes a lot of noise when it is running. [0004] (2) The cylinder piston ring wears out quickly when the air compressor is used for a long time. [0005] The above two points bring a lot of inconvenience to customers with large gas consumption, that is, they have the disadvantages of disturbing residents and high maintenance rate. [0006] After analyzing the two factors, the main problem lies in the "breathing system" of the air compressor, that is, the air filter. [0007] The existing air filter has a simple structure, and its main components are a filter element and a casing, wherein the filter element is the main fil...

AI Technical Summary

Problems solved by technology

[0003] (1) The noise of the air compressor is loud when it is running

[0004] (2), long-term use of the air compressor cylinder piston ring wears out quickly

[0007] The existing air filter has a simple structure, and its main components are a filter element and a casing, wherein the filter element is the main filtering part and undertakes the filtering work of the gas, and the casing is an external structure that provides necessary protection for the filter element, and its structure is simple , the sound insulation effect is poor, and the noise after filtering is still 60-70 decibels, which causes the air compressor to be noisy when it is running. Long-term use of the cylinder piston ring wears quickly, the service life is short, the maintenance frequency is high, and the use cost is high
