Problems solved by technology

[0002] Due to structural reasons, the current screeners for screening papermaking and cooking pulp need to be diluted with water before they can be screened. Therefore, they expand pollution, waste water resources, and reduce the cooking time. temperature, but also increases the burden on the concentration of black liquor, and also wastes energy and increases costs

Abstract

A papermaking cooking protoplasm sorter consists of motor(1), transmission device(2), vertical shaft, conical screen, separating drum an frame(3) etc. Spiral plate(11) is arranged at internal wall of conical screen, upper end(4) of vertical shaft is connected with conical screen, lower end is connected with motor(1) by transmission device(2), conical screen is installed in separating drum, pulp inlet(17) is arranged at top of separating drum and connected with conical screen, separating drum consists of pulp drum(15) installed at outer of conical screen and slag drum(16) installed at outer of pulp drum(15) and connected with conical screen opening, vertical shaft and motor(1) are fixed on frame(3). It has more yield, less black-liquor consumption and no need for water dilution, and it can save water.

Description

1. Technical field [0001] The invention relates to a pulp screening equipment for papermaking and pulping, in particular to a pulp screening machine for cooking raw pulp in papermaking. 2. Background technology [0002] Due to structural reasons, the current screeners for screening papermaking and cooking pulp need to be diluted with water before they can be screened. Therefore, they expand pollution, waste water resources, and reduce the cooking time. Temperature also increases the burden to the concentration of black liquor simultaneously, and also wastes energy, increases cost. 3. Contents of the invention [0003] The purpose of this invention is to provide a new type of pulp screener for paper cooking and cooking raw pulp, which does not need to be diluted with water when screening, and also separates impurities while screening the raw pulp, thereby ensuring various pulping for black liquor extraction. The water filter orifice of the equipment is no longer broken, wh...
