Pipeline washing silencer

Abstract

The utility model relates to the technical field of pipeline noise elimination, in particular to a pipeline washing pipe silencer which comprises a silencer shell, a water inlet and a filter body, a threaded groove is formed in the inner wall of the silencer shell, a screw is fixedly connected to one side of a filter pipe body, the filter body can be in threaded connection with the threaded groove of the silencer shell through the screw, and the water inlet is communicated with the filter body. The filter screen is movably arranged in the filter pipe body, and the outer wall of the silencer shell is movably sleeved with sound insulation cotton. Due to the fact that the threaded rod and the silencing piece can be detached in the silencer shell in a threaded mode and the sound insulation cotton on the outer wall of the silencer shell is arranged in a sleeved mode, when the silencer is used, the streamline threaded piece of the threaded rod reduces the speed of water flow while not reducing the flow of the water flow as much as possible, noise generated by the water flow is reduced, and the service life of the silencer is prolonged. And secondly, the sound insulation cotton blocks sound transmission from the outside, so that the effects of combining the inside and the outside and silencing to the maximum extent are achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of pipeline silencers, in particular to a pipeline flushing silencer. Background Art

[0002] A pipe flushing silencer is a device used to reduce shock wave noise in a pipe system. It can reduce the spread and impact of noise by absorbing, dissipating or reflecting the energy of the shock wave. The silencer usually consists of a shell, sound absorbing material and an air chamber, which work together to reduce the energy of the shock wave and convert it into other forms of energy, thereby reducing the noise level. Pipe flushing silencers are widely used in industry, construction and environmental fields to improve the comfort of the working environment and reduce noise pollution to the surrounding environment.

[0003] A pipe silencer disclosed in the Chinese utility model patent application disclosure CN 209540303 U relates to the technical field of air compressor silencer equipment. It includes a buffer air inlet, a microporous silencer mechanism and a silencer shell, and the buffer air inlet, the microporous silencer mechanism and the silencer shell are detachably connected to each other through flanges. The silencer achieves the purpose of further reducing the noise generated by the airflow in the pipeline through diffusion and reflection of the airflow in the silencer shell. However, this utility model only silences the inside of the pipeline, and does not achieve internal and external combined silence, so the silencer effect is not good. Utility Model Content

[0004] The purpose of the utility model is to provide a pipeline flushing muffler to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pipe flushing silencer comprises a silencer shell, a water inlet and a filter body, a threaded groove is provided on the inner wall of the silencer shell, both ends of the silencer shell are threadedly connected with silencer plates, a threaded silencer rod is movably provided in the silencer shell, a first flange is fixedly connected with both ends of the silencer shell, the water inlet comprises a second flange and a water inlet pipe body, the water inlet pipe body is trumpet-shaped, the first flange is fixedly connected to one side of the water inlet pipe body, the second flange can be connected to the first flange of the silencer shell, the filter body comprises a screw, a filter screen and a filter tube body, one side of the filter tube body is fixedly connected with a screw, the filter body can be threadedly connected to the threaded groove of the silencer shell by the screw, the filter screen is movably provided inside the filter tube body, and the outer wall of the silencer shell is movably sleeved with sound insulation cotton.

[0007] A third flange is fixedly connected to one side of the water inlet, and the third flange can be connected to other water pipes.

[0008] A fourth flange is fixedly connected to one side of the filter tube body, and the fourth flange can be connected to the water outlet pipe.

[0009] A gasket is movably arranged in the muffler shell, and the gasket is squeezed by the thread of the screw of the filter body and is tightly pressed and fitted with the muffler sheet.

[0010] The muffler sheet is provided with a main flow hole and a diversion hole, and the diversion holes are evenly distributed around the main flow hole.

[0011] The main flow hole and the branch flow hole are filled with sound-absorbing cotton, and the sound-absorbing cotton is fixedly arranged inside the sound-absorbing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The pipe flushing silencer is threadably detachable through the threaded rod and the silencer sheet inside the silencer shell and the sound insulation cotton sleeve arrangement on the outer wall of the silencer shell. When in use, the streamlined threaded sheet of the threaded rod slows down the speed of the water flow while minimizing the water flow rate, thereby reducing the noise generated by the water flow. Secondly, the sound insulation cotton blocks the propagation of sound from the outside, thereby achieving the effect of combining inside and outside to maximize the sound insulation effect, avoiding the poor sound insulation caused by single internal or external sound insulation.

[0014] The pipe flushing silencer is arranged by connecting the thread of the silencer shell with the screw of the filter body. When in use, the thread can be separated from the screw, and the thread can be used to connect the silencer plate with the spiral rod, which is convenient for cleaning and replacing the spiral rod, silencer plate and filter net, thereby achieving the effect of facilitating cleaning and replacement of accessories, and avoiding the situation where it is difficult to clean and replace accessories of the integrated facility.
