Solid-liquid separation device for organic silicon microsphere production

Abstract

The invention discloses a solid-liquid separation device for organic silicon microsphere production. The solid-liquid separation device comprises a suction filtration barrel, filter cloth and a slag scraping mechanism. A barrel body of the suction filtration barrel is a cylinder, a feeding port is formed in the top of the suction filtration barrel, a discharging port is formed in the bottom of thesuction filtration barrel, an interlayer is concavely arranged on the lower middle portion of the suction filtration barrel along the barrel wall to form a vacuum cavity, small holes are formed in the inner walls of the vacuum cavity to serve as filter plates, an extraction opening is formed in the bottom end of the vacuum cavity and connected with an inlet of a gas-liquid separator, and an outlet of the gas-liquid separator is connected with a vacuum pump; the filter cloth is arranged along the inner walls of the filter plates and is detachably connected with the barrel wall of the suction filtration barrel; and the slag scraping mechanism comprises a scraper blade paddle, scraper blades and a motor, the scraper blade paddle is horizontally and transversely arranged in the suction filtration barrel, the middle of the scraper blade paddle is connected with the motor through a stirring shaft, the two ends of the scraper blade paddle are connected with the scraper blades through clamps,the scraper blades are vertically arranged, and the scrapers make contact with the filter cloth. The problem of poor filtering effect caused by overlarge hydraulic pressure in the prior art is solved, the filter cloth is cleaned without shutdown in the suction filtration process, continuous production is realized, and the production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and particularly relates to a solid-liquid separation device for producing organic silicon microspheres. Background technique [0002] In the production process of silicone microspheres, there is a process of solid-liquid separation. Because silicone microspheres have the characteristics of low density and small particle size, and their size is in the micron level, a filter cloth with a high mesh number is required for filtration. When the traditional plate and frame filter press is used for solid-liquid separation, due to the excessively high filter cloth mesh, the hydraulic pressure rises very quickly, resulting in poor filtration effect; in addition, frequent shutdowns are required to clean the filter cake, which is time-consuming and labor-intensive, reducing production efficiency. If automatic mechanical filtration and cleaning are used, not only the mechanical design is complex, ...
