Technical Field

[0001] This utility model relates to the field of pulping equipment technology, specifically a high-efficiency, high-consistency pulping machine. Background Technology

[0002] High-consistency pulpers are ideal equipment for modern papermaking to process chemical pulp, mechanical pulp, and semi-chemical mechanical pulp. They are suitable for high-consistency pulping of wood pulp, straw pulp, bagasse pulp, bamboo pulp, waste paper pulp, etc. They have a wide range of applications for pulps, and can separate different types of wood such as shrubs and branches, as well as other papermaking raw materials such as cotton stalks, hemp stalks, rice and wheat straw, and reeds into good fibers.

[0003] Existing high-consistency pulpers only pulp by synchronously rotating an internal rotor and a fixed spiral pulping plate on its surface at high speed. Although they can pulp different raw materials, the fixed pitch of the spiral pulping plate means there is no room for improvement in the shredding effect, making it difficult to achieve a high pulping effect and affecting efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A high-efficiency, high-consistency pulping machine includes a pulping tank, a screen plate fixed to the bottom of the pulping tank, a hopper fixed to the bottom of the screen plate, a discharge pipe connected to one side of the bottom of the hopper, and a drive shaft vertically installed at the bottom of the hopper, penetrating the hopper and the screen plate and connected to a rotor inside the pulping tank. A fixed spiral pulping plate is fixed to the surface of the rotor, and a movable spiral pulping plate is movably sleeved on the surface of the rotor. The fixed spiral pulping plate and the movable spiral pulping plate are spirally wound together on the surface of the rotor, and pulping serrations are provided on the edges of both the fixed spiral pulping plate and the movable spiral pulping plate. The rotor has a vertically arranged guide protrusion on its surface, and a slot is slidably engaged on the surface of the guide protrusion. The slot is fixed at the inner edge of the movable spiral pulping plate. Vertical fixed connecting rods are symmetrically arranged on both sides of the rotor. The fixed connecting rods vertically penetrate the fixed spiral pulping plate and are fixedly connected to the movable spiral pulping plate. The top of the pulping tank is fixed with a fixed frame, the top of the fixed connecting rod is fixed with a connecting frame, the top of the connecting frame is vertically fixed with a connecting shaft that passes through the fixed frame, and the fixed frame is provided with a lifting drive assembly that is connected to the connecting shaft.

[0006] Preferably, the fixed spiral pulping plate and the movable spiral pulping plate have the same spiral direction and the same pitch and diameter.

[0007] Preferably, the guide ridges and slots are arranged in two sets and are symmetrically arranged on the front and back of the rotor.

[0008] Preferably, the distance between the fixed connecting rod and the inner and outer edges of the movable spiral pulping plate is equal, and the fixed spiral pulping plate is provided with a clearance hole at the position corresponding to the fixed connecting rod.

[0009] Preferably, a sliding sleeve is installed on the fixing frame, and the connecting shaft is slidably connected to the sliding sleeve.
