Problems solved by technology

[0007] In order to solve the problem that the beater in the prior art is in order to improve the beating degree of pulp, the problem of redundant equipment exists when setting multiple beaters in series or setting multiple grinding zones in one beater and once the beater in the prior art is set After finishing, it is difficult to increase or decrease the grinding area, and it is difficult to adapt to the problem of pulp change in the actual process

Abstract

The invention provides a batch refiner which comprises a shell, a moving refining plate, a fixed refining plate, a transmission shaft and a gap adjusting mechanism, wherein the moving refining plate and the fixed refining plate are coaxially arranged, and the transmission shaft is coaxially connected with the moving refining plate. The batch refiner is further provided with a fluid pushing device, a fluid inlet channel is arranged on the moving refining plate or the fixed refining plate and penetrates through two bottom surfaces of the moving refining plate or the fixed refining plate, a discharge end face of the fluid pushing device faces the fluid inlet channel, and communicated backflow gaps are reserved between the fluid pushing device and the shell as well as between each refining plate and the shell respectively. Multiple refining can be achieved by circulating pulp between the refining plates when the batch refiner is operated, and times of refining are not limited by the batch refiner; and gaps between the refining plates can be adjusted by the gap adjusting mechanism so as to adapt to changes of the pulp. The batch refiner is simple and flexible in operation.

Description

technical field [0001] The invention belongs to the field of papermaking and pulping, and in particular relates to a batch refiner and a refining process thereof. Background technique [0002] In the paper industry, the pulp from the pulping process cannot be used directly for papermaking, but must be beaten first, because the pulp fibers at this time are stiff and elastic, and contain a large number of unseparated fiber bundles, which are hard , and some are too long, some are too thick, and lack the necessary cutting and separation. If they are used to make paper, the resulting products will be loose, porous, rough in surface and low in hardness, which cannot meet the requirements of use. Hydraulic beating is the use of mechanical devices to process pulp fibers in water, and perform mechanical actions such as extrusion, kneading, cutting, and carding on the fibers to make the fibers undergo various morphological changes such as cutting, splitting, brooming, and swelling, s...
