Abstract

The invention relates to the technical field of silencing, in particular to a silencing device for a vacuum pump. The silencing device for the vacuum pump comprises a shell; a partition plate for dividing the shell into an upper half shell body and a lower half shell body is arranged in the shell; a first opening connected with an exhausting pipe of the vacuum pump is formed in the upper half shell body; two magnets opposite in magnetism are further oppositely arranged in the upper half shell body; a rotating piece is arranged between the two magnets, and is provided with a coil for cutting amagnetic induction line; an electric brush is electrically connected to the coil; a water storing cavity and a filtering cavity which are communicated are formed in the lower half shell body; an atomizing piece for atomizing water is arranged in the water storing cavity; a circuit box used for controlling high-frequency vibration of the atomizing piece is further arranged in the water storing cavity, and is connected with the electric brush; the water storing cavity is further provided with a water inflow pipe and a water outflow pipe; and the filtering cavity is provided with a second openingand a third opening. By means of the scheme, the problem that an existing vacuum pump is large in noise is solved.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to a noise reduction device for a vacuum pump. Background technique [0002] The water ring vacuum pump belongs to the wet vacuum pump, which is mostly used to extract or transport gas. With the rapid development of industrial and agricultural production and scientific research, the demand for water ring vacuum pumps in all walks of life is increasing. However, the following technical defects exist in the use of vacuum pumps : During the working process of the vacuum pump, the exhaust pipe is impacted and vibrated by the gas to produce high-level noise. After preliminary detection by the technicians with a decibel meter, the noise value reaches above 80dBA, which is severe in the degree of noise pollution and can cause serious damage to the surrounding workers. Different degrees of harm, so it is necessary to reduce the generation of noise. Contents of the invention [00...
