Sodium silicate filter pump for white carbon black production

Abstract

The invention discloses a sodium silicatefilter pump for white carbon black production. The filter pump comprises a pump body, wherein the upper part of the inner pump wall of the pump body is fixedly connected with a filter device, the left part of the upper end of the pump body is fixedly connected with a feed pipe in a penetrating manner,the upper part of the outer surface of the feed pipe is in threaded connection with a filter pipe, the middle of the upper end of the filter pipe is movably connected with a connecting pipe in a penetrating mode, the right portion of the upper end of the pump body is fixedly connected with a pressurizing device in a penetrating mode, the upper portion of the right end of the pump body is fixedly connected with an extraction device in a penetrating mode, the lower portion of the inner pump wall of the pump body is fixedly connected with a discharging device, the lower portion of the outer surface of the pump body is fixedly connected with four supporting legs, the lower ends of the four supporting legs are fixedly connected with non-slip mats, and the middle of the lower end of the pump body is fixedly connected with a discharging hopper in a penetrating mode. According to the filter pump for white carbon black production, the whole filter pump is high in filtering speed and good in filtering effect, a filter screen can be cleaned, and the filter pump is suitable for wide application.

Description

technical field [0001] The invention relates to the technical field of white carbon black production, in particular to a water glass filter pump for white carbon black production. Background technique [0002] White carbon black, also known as hydrated precipitated silica, is a white amorphous fine powder, mainly used as a reinforcing agent for rubber. In the production process of white carbon black, water glass is needed, and water glass is also called sodium silicate. It is a colorless, transparent viscous solid. Sodium silicate is calcined from quartz sand and sodium carbonate. It is alkaline when dissolved in water. Its transparent slurry solution is called water glass. Sodium silicate is decomposed by acid and precipitated. The colloidal solution of silicic acid, commercially available product exists with aqueous solution or solid form, because the existence of impurity, is green or blue usually, inventor finds that there are following problems at least in the prior art...

[0002] White carbon black, also known as hydrated precipitated silica, is a white amorphous fine powder, mainly used as a reinforcing agent for rubber. In the production process of white carbon black, water glass is needed, and water glass is also called sodium silicate. It is a colorless, transparent viscous solid. Sodium silicate is calcined from quartz sand and sodium carbonate. It is alkaline when dissolved in water. Its transparent slurry solution is called water glass. Sodium silicate is decomposed by acid and precipitated. The colloidal solution of silicic acid, commercially available product exists with aqueous solution or solid form, because the existence of impurity, is green or blue usually, inventor finds that there are following problems at least in the prior art and has not been solved: 1, traditional filter pump The filtration speed of water glass is slow, and the filtration effect of water glass is poor, which affects the filtration quality of water glass; 2. The traditional filter pump is not convenient for cleaning the filter screen, which causes the filtered impurities to easily block the filter screen , reduces the filtration efficiency of water glass; therefore, we propose a water glass filter pump for the production of white carbon black
