Description

Air filter post-treatment silencer of air compressor

Technical Field

The utility model belongs to the technical field of air compressors, relates to an air filter, and particularly relates to an air filter post-treatment silencing device.

Background

The air filter of the air compressor is used for filtering impurities such as dust and particles in the entering air. The air compressor machine admit air the noise big, has seriously influenced user's use and has experienced, consequently most empty filter all have the amortization function, like the utility model patent of the patent number of my department application for "202021508842.5" air filter for air compressor machine, "it carries out the amortization to the noise through the annular sound channel, has effectively reduced noise pollution. Although the air filter has a silencing function, the unapproved noise can cause discomfort to workers, especially when a plurality of air compressors work and start simultaneously, so how to carry out secondary silencing on the air filter is the technical problem to be solved by the utility model.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: how to carry out secondary silencing on the air filter.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:

the air filter post-treatment silencing device for the air compressor comprises a sealing shell, wherein a silencing chamber is arranged inside the sealing shell, a hollow cylindrical silencing pipe is arranged in the silencing chamber, a mounting hole communicated with the silencing chamber is formed in one end of the sealing shell, a circle of extending part located at the outer edge of the mounting hole is formed in the position, corresponding to the outside of the sealing shell, of the mounting hole, and an aluminum threaded part is embedded in the extending part.

Preferably, the sound-deadening chamber has a cylindrical shape.

Preferably, three rows of the silencing tubes are arranged on one side, opposite to the mounting hole, in the sealed shell, and the silencing tubes in adjacent rows are arranged at intervals.

Preferably, a circle of the silencing tubes wound around the mounting hole in an equiangular array is arranged on one side, corresponding to the mounting hole, in the sealed shell.

Preferably, the sealing shell is composed of an upper shell and a lower shell, and the silencing chamber is arranged between the upper shell and the lower shell together.

Preferably, the inside of going up the casing is provided with and is located the spliced pole in the amortization room, the bolt of casing down is screwed in the spliced pole with go up the casing and link firmly.

Preferably, a plurality of reinforcing ribs are arranged in an equidistant array outside the extension part.

Compared with the prior art, the utility model has the beneficial effects that:

the air outlet pipe of empty straining inserts in this device, and the noise of production is through the inside hush pipe secondary amortization of hush chamber, has further reduced the running noise of air compressor machine.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below.

FIG. 1 is a schematic view of a muffler assembly;

FIG. 2 is a cross-sectional view of a muffler assembly;

FIG. 3 is a schematic structural view of the upper housing;

fig. 4 is a schematic structural view of the upper case.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Examples

Referring to fig. 1 and 2, the silencer assembly includes a sealed housing 10 within which is disposed a silencer chamber 20, preferably cylindrical in shape. A hollow cylindrical silencing tube 30 is arranged in the silencing chamber. One end of the sealed shell is provided with a mounting hole 40 communicated with the silencing chamber, the air outlet pipe of the air filter is inserted into the mounting hole, and the noise sound wave after the air filter is silenced is secondarily silenced by the silencing pipe. Referring to fig. 2 and 3, three rows of silencing tubes 30 are arranged on one side of the interior of the sealed shell, which is opposite to the mounting hole, the silencing tubes in adjacent rows are arranged at intervals, and one circle of silencing tubes 30 which are arranged around the mounting hole in an equal-angle array is arranged on one side of the interior of the sealed shell, which corresponds to the mounting hole.

The sealing shell is of an injection molding structure, and the shell is designed into a split structure in order to facilitate the forming of the silencing pipe. Preferably, the sealed housing is composed of an upper housing 11 and a lower housing 12, and a silencing chamber is arranged between the upper housing and the lower housing together. The inside of going up the casing is provided with the spliced pole 13 that is located the amortization indoor, and the bolt of lower casing is screwed into the spliced pole and is linked firmly with last casing. The amortization is also participated in to the arc outer wall of spliced pole, can further promote the noise cancelling effect of this device.

A circle of extension parts 14 located at the outer edges of the mounting holes are arranged at the positions, corresponding to the mounting holes, of the outer portion of the sealing shell, aluminum threaded parts are embedded in the extension parts, and the air outlet pipe of the air filter is screwed into the threaded parts. Preferably, a plurality of reinforcing ribs 15 are arranged in an equidistant array outside the extension to ensure the strength of the extension.

In conclusion, the post-treatment silencing device is additionally arranged at the rear end of the air filter, and noise sound waves of the muffled air filter are secondarily silenced by the silencing pipe in the silencing chamber, so that the running noise of the air compressor is further reduced, and the noise pollution is eliminated.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
