Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a double-feed disc refiner. When driving the moving grinding table, it is necessary to overcome the huge friction force brought by the drum gear coupling at the motor end when it is loaded and rotating, resulting in uneven pressure and inconsistent gaps between the two grinding areas, resulting in the grinding discs in the two grinding areas There are technical problems such as inconsistent wear and tearing of the pulp produced by the two grinding zones.

Abstract

The invention relates to papermaking pulping equipment, in particular to a double feed disk pulping machine. The invention is mainly used for solving the technical problems that as the existing pulping machines of the prior art control the intervals of grinding zones and the balancing axial thrust by single feed, when the moving grinding disk is driven, the pressure among the grinding zones is uneven and the intervals among the grinding zones are inconsistent, therefore, the wear of the grinding disc of the two grinding zones is inconsistent. The invention comprises a left body and a right body, wherein, the left body is provided with a bearing base, the bearing base is internally equipped with a main shaft through the bearing, the left body and the right body are respectively provided with a left moving seat and a right moving seat which are both connected with static grinding discs, a grinding and cutting chamber capable of grinding and cutting paper pulps is formed between the leftmoving seat and the right moving seat, the main shaft stretches into the grinding and cutting chamber and is connected with a rotating body, and a moving grinding disc is fixedly connected with the two sides of blades of the rotating body; the left moving seat and the right moving seat are respectively connected with a left hydraulic cylinder and a right hydraulic cylinder capable of driving the left moving seat and the right moving seat to move.

Description

technical field [0001] The invention relates to a paper refining equipment, in particular to an improvement on the structure of a double-feed disc refiner and the like. Background technique [0002] The basic process of papermaking production is to dissociate and disperse various plant fiber raw materials into pulp through different methods, then grind and beat them into fibers of a certain shape, and finally rearrange them to form paper sheets. Therefore, refining is one of the most critical processes in paper production, which directly affects the quality of paper products. The double-disc refiner has the advantages of low refining power consumption determined by its structural characteristics, a wide range of pulp types, and high-efficiency beating. In addition, it is suitable for mechanical pulping and high-consistency beating. Refining equipment is more widely used. The Chinese patent discloses a sealed self-priming non-clogging double-disc paper refiner (authorized a...
