High-concentration hydrapulper with sieve plate

Abstract

The invention discloses a high-concentration hydrapulper with a sieve plate. The high-concentration hydrapulper comprises a tank body and a rotor arranged in the tank body, wherein the rotor is connected with a transmission device, the sieve plate is arranged below the rotor in a matched mode, a fine pulp chamber is formed below the sieve plate, and a pulp outlet is formed in the fine pulp chamber; the tank body is mainly composed of a barrel and a lower end socket coaxially connected to the lower end of the barrel; the lower end socket is of a smooth transition spherical surface structure, and flow guide plates diffusing outwards are arranged on the inner wall of the lower end socket around the sieve plate in a circumferential direction; the rotor is a spiral rotor and is mainly composedof a mandrel, a spiral blade arranged on the mandrel and a rotor base plate arranged at the bottom of the mandrel; the mandrel comprises a conical mandrel section at the lower portion and a straight mandrel section at the upper portion; and the small-diameter end of the upper end of the conical mandrel section and the straight mandrel section are coaxially fixed in a butt joint mode. With the high-concentration hydrapulper, waste paper can be quickly disintegrated under the condition of a high concentration, the pulp property of the waste paper is kept as much as possible, a pulp treatment concentration can reach 10%-15%, working efficiency is greatly improved, and energy conservation and consumption reduction are achieved.

Description

Technical field [0001] The invention belongs to the technical field of papermaking equipment, and particularly relates to a high-concentration hydraulic pulper with a sieve plate. Background technique [0002] The traditional high-concentration hydraulic pulper is mainly used for high-concentration crushed waste paper and ink separation in the deinking process, and the processing slurry concentration can reach 10% ~ 15%. It is mainly composed of a trough, a rotor and a transmission mechanism. When working, the material that enters the cylinder and needs to be disintegrated, under the continuous impact, collision, friction, and decomposition of the rotating spiral rotor, can achieve gentle beating in a high-concentration state, and effectively mix the liquid medicine, and at the same time, the fiber Friction makes the ink particles sufficiently separate from the fiber surface. The slurry with higher whiteness after deflation is discharged from the slurry outlet and enters the ne...

Problems solved by technology

[0012] Although the technical solution is provided with a good pulp cavity, the good pulp cavity and the shredder cavity are fixed through a number of fixed propeller-shaped blades uniformly distributed in the circumferential direction with the rotor axis as the center line, and the direction of rotation of the propeller-shaped blades is consistent with that of the shredder. It is realized by the scheme that the screw blades of the pulper rotor rotate in the same direction, and the screening effect is poor in actual use
