Air cylinder silencer

Abstract

The invention discloses an air cylinder silencer. The air cylinder silencer comprises a silencing pipe and a connector and further comprises a silencer shell; the connector is fixed to the silencer shell; the silencing pipe is arranged in an inner cavity of the silencer shell; the first end of the silencing pipe is connected with the connector; the other end of the connector is an air inlet connecting opening and extends out of the silencer shell; the silencing pipe is a pipe body made of an elastic materials; multiple pipe wall micro air holes are formed in the pipe wall of the pipe body; and an air outlet communicating with the inner cavity is further formed in the silencer shell. According to the air cylinder silencer, waste compressed air of an air cylinder enters the silencing pipe through the air inlet connecting opening of the connector, then is split, discharged and released through the multiple pipe wall micro air holes of the silencing pipe, and then is discharged and released secondarily through the air outlet in the silencer shell, and the very ideal pressure reduction and silencing effects are achieved; in addition, the silencer is few in accessories, simple in structure, easy to assemble and disassemble and low in cost.

Description

technical field [0001] The invention relates to a muffler, in particular to a cylinder muffler. Background technique [0002] Existing cylinder mufflers are single mufflers, generally made of copper sintered, screen, filter, filter cloth and other materials, for example: copper sintered muffler and screen muffler; the above mufflers exist The noise reduction effect is poor, the exhaust resistance is large, and the service life is short, which will cause excessive noise in the machine or working environment, and the muffler needs to be cleaned or replaced frequently. [0003] For this reason, China Invention Patent No.: 2004100977681, name: prebaked anode aluminum electrolytic cell cylinder muffler, announcement date: July 18, 2007, its structure consists of a primary air pressure diffusion branch pipeline, a secondary air pressure diffusion main pipeline and removed Composed of on-site exhaust pipelines, the first-stage air pressure diffusion branch pipeline is composed of ...

AI Technical Summary

Problems solved by technology

[0004] But the cylinder muffler of above-mentioned structure still has the following deficiencies: (1) the above-mentioned prebaked anode aluminum electrolytic cell cylinder muffler adopts the air-flow guidance mode of primary and secondary air pressure diffusion, and the air pressure in the muffler It is diffused step by step, and the air flow rate is also reduced step by step. The entire silencer pipeline is longer and larger in volume; (2) The first-level air pressure diffusion branch pipeline includes the ground cylinder exhaust port joint, rubber hose, pipe collar, and elbow , double-ended spiral pipe and threaded tee; the secondary air pressure diffusion main pipeline consists of joints and main pipeline steel pipes; the removed on-site exhaust outlet pipeline is composed of steel right-angle elbows and exhaust steel pipes, and the entire silencer pipe There are many accessories involved in the road, the structure is complicated, the installation process is difficult, the assembly and disassembly are troublesome, it is not conducive to cleaning and maintenance, and the cost is high, so it is not suitable for promotion and use
