Embodiment 1

[0023] A paper pulping system, such as figure 1 Shown, comprise rope winch 1, hydropulper 2, cylindrical screen 5, sediment well 3, grab hoist and impurity separator 4, rope winch 1 passes garbage rope 14 and in hydropulper 2 Junk connections.

[0024] like figure 2 As shown, the rope winching machine 1 of the present embodiment comprises a body 15, two guide wheels 13, a rope twisting wheel 12 and a rope pressing wheel 11. The surface of the rope pulley 12 is provided with a rope-grabbing protrusion group, and the rope-grabbing protrusion group is provided with a plurality of ladder-like protrusions 121, and the plurality of ladder-like protrusions 121 are mutually parallel and evenly distributed around the center line of the twisted rope wheel 12; Sheave 11 is positioned at the top of sheave sheave 12, and the two ends that press rope sheave 11 are arranged on the both sides of body 15; Garbage rope 14 enters between the twisted rope wheel 12 and the pressure rope wheel ...

Embodiment 2

[0029] A paper pulping system of this embodiment differs from Embodiment 1 in that, as image 3 As shown, the cylindrical screen 5 of this embodiment includes a motor, a casing and a screen drum. The motor is connected to the screen drum for driving. The screen drum is arranged inside the casing, and a water slurry recovery chamber is provided between the screen drum and the casing. The lower part is provided with a good pulp pipe 54 connected with the water slurry recovery chamber; the inside of the screen drum is provided with a spiral piece, and the spiral piece is arranged in a spiral shape around the central axis of the screen drum; one end of the screen drum is provided with a feed port, and the other end is There is a slag outlet. The screen drum of this embodiment is provided with helical blades to prolong the time for the slurry to pass through the cylindrical screen 5, so that the impurities and fibers of the slurry can be better separated, and the screening effect i...

Abstract

The invention relates to the technical field of papermaking, and in particular relates to a system for papermaking pulping. A strander is connected with sundries in a hydrapulper by a garbage rope; the hydrapulper comprises a groove body and a rotor, and the rotor is arranged in the groove body; a residue inlet of a sediment well is communicated with the groove body of the hydrapulper, and the upper part of the sediment well is provided with an overflowing opening; the overflowing opening of the sediment well is communicated with a material inlet of an impurity separator, and a light impurity outlet of the impurity separator is communicated with a material inlet of a drum sieve; the drum sieve is provided with a qualified pulp pipe, and an opening of the qualified pulp pipe is arranged facing to the groove body of the hydrapulper; and a grab bucket of a grab bucket lifter is arranged above the sediment well in a liftable way, and when the residue is removed, the grab bucket extends into the bottom of the sediment well to grab the waste residue and move to a waste residue collecting position. The rotor of the system continuously works, and the strander and the impurity separator continuously clean the garbage in a pulper, so that the system for papermaking pulping can effectively and continuously work, the residue-cleaning recovery fiber cooperatively treated by the drum sieve can be recycled, and the use ratio of the fiber can be improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a pulping system for papermaking. Background technique [0002] The pulping process in the papermaking process is particularly important and is the prerequisite for papermaking. At present, the general process of papermaking and pulping is that the chain plate machine conveys raw materials, then pulps, passes through high-concentration slag remover, coarse screen, grading sieve, low-concentration slag remover, reverse slag remover, fine screen, multi-disc and hot Disperse for impurity removal treatment, and then go through disc grinding treatment and enter the paper machine for papermaking. In the pulping process, the effect of pulping is very significant. The effect of pulping directly affects the production efficiency of the entire papermaking process and the quality of finished paper. The current pulping process is difficult to achieve continuous pulping, and the fiber u...
