Abstract

The invention discloses a filtrate flow-guiding silencer. The filtrate flow-guiding silencer comprises a drum body, wherein the top end of the drum body is connected with a liquid inlet pipe, the upper part in the drum body is provided with a flow-guiding device, the flow-guiding device is composed of filtrate baffles interlaced and fixedly connected to the inner wall of the drum body, and an S-shaped flow-guiding area is formed among the filtrate baffles; the lower part in the drum body is provided with the silencer, the tail end of the silencer is connected with a filtrate drainage pipe, the silencer device is composed of three layers of silencing drums, each layer of silencing drum is fixedly connected to the inner wall of the drum body. The filtrate vapor and water mixture is buffered and silenced in the filtrate water emission process, so that the liquid speed is reduced, the emission is uniform, and the sound wave produced by compressing air high-pressure blast can be dispersed; the noise is eliminated, the working performance of a filter press is improved, the field operation environment is optimized, and the staff work load is lightened.

Description

technical field [0001] The invention belongs to the technical field of mining machinery manufacturing, and relates to a filter press, in particular to a filtrate diversion noise reduction device. Background technique [0002] The filter press is widely used in the slurry dehydration process of pulp mineral processing and chemical industry. It mainly uses a pressure pump to press the pulp into the airtight filter chamber formed by two adjacent filter plates, so that the pressure difference is formed on both sides of the filter cloth, and the pulp With the help of pressure, supplemented by the action of compressed air and high-pressure wind, the filtrate passes through the filter cloth and flows along the groove of the filter plate to the corner channel of the plate frame to be discharged concentratedly, while the solid material is trapped in the middle of the filter cloth to form a filter cake, in which the filtrate and Compressed air and high-pressure air are directly discha...
