Abstract
The invention discloses a drum screening pulp kneader, which comprises a pulp kneader drum, and the pulp kneader drum is divided into a pulping area drum and a screening area drum, a baffle board is arranged on the inner wall of the pulping area drum, and the structure form of the pulping area drum comprises a first screening area drum, a pulping area drum which is fixedly connected with the first screening area and a second screening area drum which is fixedly connected with the pulping area drum in turn. When slurry which is primarily broken is untwined, the pulp is firstly screened by the first screening drum, and acceptable pulp fiber is screened out from raw material, and raw material which is not untwined gets into the pulping drum, a large amount of energy resource is reduced, and raw material which is not untwined is avoided from being coated by the acceptable pulp, and pulping efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of papermaking equipment, relate in particular to a kind of collect the screening and pulping be the papermaking equipment of one.
Background technology
The advantage of cylinder pulper is to decompose waste paper fibre under the prerequisite of not shredding gob and generation fiber fines, need not to consume energy in unnecessary stirring, cut staple and impurity, and it is lower to consume energy; Its cylinder comprises pulp crushing area and screening area, the operation principle of pulp crushing area, the waste paper that enters pulp crushing area is soaked by water and chemicals, because cylinder slightly tilts, waste paper is relied on the power effect for support and is moved forward lentamente, and constantly the waste paper pocket is risen and at the bottom of certain height is dropped tube with it at the dividing plate of inner wall of rotary drum, utilize shearing force that waste paper fibre is discongested and do not make the gob fragmentation.Waste paper at pulp crushing area after discongesting, enter the porose screening area of Surface Machining, herein, paper pulp is diluted, the water injector of sparse water above being installed in screening area adds, like this can be with in the fiber recoil rollback tube that is blocked in the sieve aperture, good slurry flows into pulp storage tank from the sieve aperture of screening area, and gob is then discharged by the other end of rotary screen.
The problem that prior art exists is that the cylinder pulper is when discongesting the slurry of the preliminary size degradation of process, raw material and qualified paper pulp fiber mix, make paper pulp fiber and do not discongest the top that raw material takes the pulping cylinder simultaneously to, a large amount of energy have been wasted, and qualified paper pulp fiber parcel is not discongested raw material, and pulping efficient is reduced greatly.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of screening effect is good, the roller screening pulp kneader of energy savings.
For achieving the above object, technical scheme of the present invention is: roller screening pulp kneader, comprise the pulper cylinder, described pulper cylinder is divided into pulp crushing area cylinder and screening area cylinder, the inwall of described pulp crushing area cylinder is provided with dividing plate, the second screening area cylinder that the version of described pulper cylinder is the first screening area cylinder, the pulp crushing area cylinder of fixedlying connected with the described first screening area cylinder successively, fixedly connected with described pulp crushing area cylinder.
As a kind of improvement, the porch of the described first screening area cylinder is provided with the mixed cylinder of paper pulp.
As a kind of improvement, the second screening area cylinder that the version of described pulper cylinder is the first screening area cylinder, the pulp crushing area cylinder of fixedlying connected with the described first screening area cylinder successively, fixedly connected with described pulp crushing area cylinder, the second pulp crushing area cylinder of fixedlying connected, the three screening district cylinder of fixedlying connected with the described second pulp crushing area cylinder with the described second screening area cylinder.
As a kind of further improvement, be installed with spiral helicine stock guide on the inwall of described screening area cylinder.
As a kind of further improvement, also be provided with sieve aperture on the barrel of described pulp crushing area cylinder.
As a kind of further improvement, the diameter of described screening area cylinder is less than the diameter of described pulp crushing area cylinder.
As a kind of further improvement, the end of described dividing plate is provided with zigzag and discongests tooth.
As a kind of further improvement, be provided with the tooth of discongesting that pulp crushing area roller tube center is pointed in some its tips between described adjacent two dividing plates.
Owing to adopt technique scheme, roller screening pulp kneader, comprise the pulper cylinder, described pulper cylinder is divided into pulp crushing area cylinder and screening area cylinder, the inwall of described pulp crushing area cylinder is provided with dividing plate, the second screening area cylinder that the version of described pulper cylinder is the first screening area cylinder, the pulp crushing area cylinder of fixedlying connected with the described first screening area cylinder successively, fixedly connected with described pulp crushing area cylinder; When the slurry of so preliminary size degradation is discongested, at first pass through the screening of the described first screening area cylinder, qualified paper pulp fiber is sieved from raw material, have only the raw material of not discongesting to enter the pulping cylinder, a large amount of energy have been saved, and avoided qualified paper pulp fiber parcel not discongest raw material, improved pulping efficient greatly.

The specific embodiment
Embodiment one: as shown in Figure 1 and Figure 2, roller screening pulp kneader, comprise the pulper cylinder, described pulper cylinder is divided into pulp crushing area cylinder 11 and screening area cylinder 61,62, the inwall of described pulp crushing area cylinder 11 is provided with dividing plate 2, the second screening area cylinder 62 that the version of described pulper cylinder is the first screening area cylinder 61, the pulp crushing area cylinder 11 of fixedlying connected with the described first screening area cylinder 61 successively, fixedly connected with described pulp crushing area cylinder 11.
Be installed with spiral helicine stock guide 7 on the inwall of described screening area cylinder 61,62.The diameter of described screening area cylinder 61,62 is less than the diameter of described pulp crushing area cylinder 11.This version can make described pulp crushing area cylinder 1 turn round with different rotational line speed respectively with screening area cylinder 6, and what assurance obtained respectively discongests and screening effect.
The pulp crushing area cylinder cross-sectional structure of present embodiment as shown in Figure 2, the end of described dividing plate 2 is provided with zigzag and discongests tooth 31.Its operation principle is: played and move to the waste paper group on cylinder top by the dividing plate pocket, rely on gravity and inertia, waste paper group drops downwards, and this moment, the tooth of discongesting of dividing plate tore waste paper group, waste paper group is launched and falls; When falling the bottom, the tooth of discongesting of the dividing plate of bottom further decomposes waste paper again; Present embodiment has strengthened the ability of discongesting of cylinder pulper, and is simple in structure, discongests efficient and improves more than 30%.
