Abstract

The invention provides a vacuum multi-disc pulp washer which comprises a rack. One side of the rack is provided with a transmission side bearing device. The other side of the rack is provided with a distribution valve side bearing device. The rack is provided with multiple segments of pulp washing regions. Each pulp washing region comprises a pulp washing groove. The pulp washing grooves are communicated through a pulp feeding system. A plurality of filtering circular discs are arranged in each segment of the corresponding pulp washing groove. The filtering circular discs are connected with a circular disc shaft. The end, close to the transmission side bearing device, of the circular disc shaft is connected with a transmission device. The end, close to the distribution valve side bearing device, of the circular disc shaft is connected with a vacuum system through a distribution valve. The vacuum system is further connected with the filtering circular discs. Through multiple segments of washing, the whiteness of pulp is improved, the pulp is concentrated in the washing process, multiple purposes are achieved through the vacuum multi-disc pulp washer, and water consumption is saved.

Description

technical field [0001] The invention relates to the field of pulp washing and concentrating machines, in particular to a vacuum multi-disc pulp washing machine. Background technique [0002] The vacuum multi-disk thickener is a kind of slurry thickening equipment used in the pulping process. Its pulp concentration is 0.8-1%, and the pulp concentration is 8-10%. At present, the vacuum multi-disc concentrator is mostly used for the concentration of slurry, but through the observation and detection of the slurry and water quality state during the concentration process of the vacuum multi-disc concentrator, it is found that the slurry is concentrated on the disc with the rotation of the disc. The resulting slurry and water quality states were significantly different. With the rotation of the disk, the quality of the concentrated water is different at different circumferential positions, and the whiteness of the obtained slurry is significantly improved compared with that of the...
