Pulping machine for papermaking

Abstract

The invention discloses a pulping machine for papermaking. The pulping machine comprises a machine frame, a large paper pulp recycling box, a filtering box, a cutting box, a grinding machine and an air hammer, wherein the large paper pulp recycling box is arranged on one side of an air compressor, one side of the large paper pulp recycling box is provided with the filtering box, one side of the filtering box is provided with a vibrating screen, one side of a vibration motor is provided with the cutting box, the top of a fine paper pulp outlet is provided with the grinding machine, an upper grinding wheel is arranged on one side of the grinding machine, and a lower grinding wheel is arranged on one side of the upper grinding wheel; a grinding motor is arranged on one side of the lower grinding wheel, one side of the grinding motor is provided with a discharge port, and one side of the discharge port is provided with the air hammer. Paper pulp obtained after cutting can be filtered, so that the size of the filtered paper pulp is uniform, the large paper pulp can be recycled and reused, and energy is saved; meanwhile, the pulp discharging rate is high, the paper pulp cannot adhere to the inner wall of the outlet, and the pulping machine is convenient to use.

Description

Technical field [0001] The invention relates to a refiner, in particular to a refiner for papermaking. Background technique [0002] At present, in order to make the pulp more flexible, paper companies generally use a refiner to refine the pulp. However, the current refiner only uses two grinding discs to refine the pulp, which has poor refining effect. , The disadvantage of low refining efficiency. At the same time, there is no filter device for different sizes of pulp, resulting in uneven pulp size, which affects the use effect. At the same time, the large pieces of filtered paper are not recycled, wasting resources, and the pulp outlet after grinding Easily stained with pulp, while the pulp output rate is low. [0003] Therefore, how to design a refiner for papermaking has become a problem to be solved at present. Summary of the invention [0004] The purpose of the present invention is to provide a refiner for papermaking to solve the problems raised in the background art. [0...

Problems solved by technology

[0002] At present, in order to make the pulp more flexible, paper-making enterprises generally use a refiner to refine the pulp. However, the current refiner only uses two grinding discs to refine the pulp, and the refining effect is poor. , the disadvantage of low refining efficiency. At the same time, there is no filtering device for pulp of different sizes, resulting in uneven pulp size, which affects the use effect. At the same time, the large pieces of filtered paper have not been recycled, wasting resources. Easy to contaminate pulp with low output rate
