Abstract

The invention relates to a side pressure concentrator with clamping mesh, which includes a frame, a mesh cage is installed in the middle of the right side of the frame, a slurry tank is installed outside the mesh cage, and a sewage tank is installed at the bottom of the mesh cage. The sewage tank is fixedly installed on the bottom of the frame, the outer side of the cage is equipped with a filter screen, the top of the slurry tank is provided with a pulp inlet pipe, and the filter screen is matched with the outer surface of the cage through rubber rollers . The side pressure thickener can improve the filtration efficiency of sewage in the slurry, reduce the wear and tear of the equipment, and increase the output and slurry concentration.

Description

technical field [0001] The invention relates to the field of paper production equipment, in particular to a sandwich side pressure concentrator. Background technique [0002] In the side pressure thickener currently used in the paper industry, the slurry enters the slurry tank, and the pressure is generated by the potential difference of the slurry, so that the sewage in the slurry is filtered through the filter on the cage and discharged into the cage, and is retained by the filter cloth of the cage. The high-quality pulp rotates with the cage, enters the rubber roller to be squeezed, and further discharges the sewage. The pulp adhering to the rubber roller is scraped off by the scraper and falls into the pulp tank. [0003] The existing side pressure concentrator has the following defects during use: [0004] 1. When the slurry inlet concentration is low, the slurry level difference is limited, the water filtration pressure difference is low, the sewage is discharged slow...
