In the existing technology, papermaking is generally divided into pulping, modulation, papermaking, processing and other steps. Pulping is the first step in papermaking, and this step is achieved through a pulper. The principle is that the pulp circulates in the trough, and through the action of the flying knife, it produces horizontal cutting, vertical splitting, swelling and other effects, thereby making a pulp that meets the requirements of papermaking.

[0003] In the prior art, Chinese patent publication number CN208501374U discloses a pulper capable of producing clean pulp, comprising a frame and a tank body, the frame and the tank body are connected by welding, the tank body comprises an upper tank body and a lower tank body, an electromagnetic valve is arranged between the upper tank body and the lower tank body, a motor is fixed on the top of the upper tank body, the output shaft of the motor is connected to the reducer, the motor drives the rotating shaft to rotate, so that the spiral blade on the rotating shaft cuts the pulp, and at the same time, the rotating plate and the connecting plate rotate with the rotating shaft, and the moving block connected to the connecting plate slides on the track, driving the rotating disk to scrape the bottom of the upper tank body back and forth, reducing the pulp deposition at the bottom, and enabling the spiral flying knife to cut the pulp scraped from the bottom, evenly pulping, thereby improving the quality of the pulp, filtering the pulped pulp through the screen plate, and utilizing the inertia of the pulp and the elasticity of the spring to prevent blockage caused by filtering a large amount of pulp, quickly filtering the pulp, and the pulper produces clean pulp.

[0004] However, when the utility model is actually used, when the pulp is filtered, if the crushing is not thorough enough, there will be large pulp particles, which will be restricted by the sieve holes, so that they block the sieve holes, and large particles are difficult to pass through, affecting subsequent discharging. After discharging, some pulp will remain on the inner wall of the pulper, which makes it inconvenient to clean the inside of the pulper, so improvement is needed. Utility Model Content
