Concentration device in silica sol production process

Abstract

The invention discloses a concentration device in a silica sol production process, and belongs to the technical field of silica sol production equipment. The concentration device comprises an outer cylinder; a filtering drum is mounted in the outer cylinder, the upper end and the lower end of the filtering drum are respectively provided with a feeding port and a discharging port, and the filtering drum is connected with a driving device for driving the filtering drum to rotate; a water outlet is arranged in the lower end part of the outer cylinder, and a cleaning device is arranged on the outer wall of the outer cylinder; and flow-choking walls are arranged in the filtering drum. In the concentration device in the silica sol production process, a high-pressure flow-dividing pipe can wash filtration pores in the filtering drum so as to maintain the smoothness of the filtration pores and guarantee the filtering efficiency; the silica sol is choked by the flow-choking walls after entering the drum, so that the silica sol cannot reach the bottom of the drum quickly, but enters the drum layer by layer, thereby improving the filtering efficiency.

Description

technical field [0001] The invention relates to the technical field of silica sol production equipment, in particular to a concentration device in a silica sol production process. Background technique [0002] In the production and preparation process of silica sol, it is necessary to obtain silica sol products with different concentrations. However, in the dehydration process of silica sol, because the silica sol has a certain viscosity, the filter drum is prone to blockage after long-term work, which affects the production efficiency. When cleaning the inside of the concentrating device, the concentrating device must be disassembled, which makes it very difficult to clean and maintain the filter cartridge inside the concentrating device. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies of the prior art, the present invention provides a concentration device in a sol production process. [0004] The present invention is achieved through the following technical...
