Abstract
The utility model relates to a pulping mechanism, which is to solve the problems existing in the prior art of poor refining result and high cost. The utility model comprises two parallel spiral rollers that are meshed with each other and rotate with the same direction; a spiral roller comprises a feeding spiral part, a positive spiral sleeve and a negative spiral sleeve; the thread pitch of the positive spiral sleeve takes a descending tendency to be a gradually reducing area, which has a compressing and pushing effect on pulp material. The negative spiral sleeve drives reversely; refined pulp material is extruded from the oblique groove provided on the thread edge of the negative spiral sleeve. Pulp material is cut, extruded in the high-pressure area formed by the positive spiral sleeve and the negative spiral sleeve, and finally realization of separation, wire division, broomed end and crashing of fiber is achieved that the pulp material becomes pulp. The utility model has the advantages of good quality for paper pulp, ability to conduct consecutive production of pulp, saving energy with lower energy exhaustion, convenience for maintenance, multi-functions in one machine, more compact pulping procedure, small pollution and easiness for promotion for wider use.
Description
Affiliated technical field
The utility model relates to a kind of pulping equipment, especially with slurrying, bleaching, wash multi-functional pulper in one.
Background technology
Traditional pulping equipment is discongested and brooming pulp fiber, belong to cutter formula mill (beating) slurry equipment, this cutter formula refining equipment, the fluted disc that uses precious metal material to do, its maintenance and renewal cost are very high, the 10-15% that competes to reach the disc mill cost that has, and in the cutter tooth wear process, running down qualitatively of defibrination quality and slurrying product used nonmetal modified fluted disc later on again, but still can not have been reduced the defibrination specific energy consumption.This by the changes in material that improves equipment, and is difficult to reduce defibrination process energy consumption, improves the defibrination quality.
Summary of the invention
For overcoming the deficiency of above-mentioned technology, the utility model provides a kind of pulper of new structure, make material under the mutual propelling movement that right-handed screw cover and backpitch overlap, in formed higher-pressure region, be subjected to shearing force and fiber axis under the extruding force effect, fiber is subjected to separating, discongests, brooming is divided intensive treatment such as silk, conquassation, realizes reducing the purpose of refining energy consumption raising defibrination quality.
The technical scheme that its technical problem that solves the utility model adopts is: by motor by the transmission distributor box, drive two be engaged with each other, propellers parallel, that rotate in the same way, propellers are by defeated material spiral part, right-handed screw cover and backpitch cover (one positive one counter be a defibrination section, every equipment can be adorned 3-5 group defibrination section) are formed.The pitch of right-handed screw cover forms " taper " from large to small, slurry is produced compression and propelling, and backpitch overlaps reverse promotion, therefore accumulates gradually, is full of at positive and negative screw casing intersection material, forms the back-pressure district.In the back-pressure district, fiber is subjected to very big extruding force, impels the fiber cracking, has strengthened soaking into of soup and separating of fiber, makes the fibrous inside fibrillating, has improved flexibility, the plasticity of fiber.Slurry through the defibrination refinement, extrude by the skewed slot place that is opened on the backpitch cover spiral shell rib, enter next mill district, separate through repeatedly grinding, just can reach the effect of defibrination, also utilize the perforation of the vertical and horizontal of spiral simultaneously, improve the high-effect mixing of slurry, soup, even defibrination, slurrying has improved pulp quality greatly continuously.
The utility model has the advantages that a tractor serves several purposes (with slurrying, bleaching, making beating, wash in one) makes pulping process more compact; Equipment is terse, easy to maintenance, the building block system combination can be rolled over dress increase and decrease defibrination group as required arbitrarily; Energy-saving and cost-reducing; Slurrying continuously, pulp quality is good; Blowdown flow rate is few, helps environmental protection; And applied range will play a role in wide spectrum.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.

1. charging apertures, 2. water inlet pipe mouths, 3. soup mouths, 4. leakage fluid drams, 5. discharging openings, 6. defeated material spiral 7. right-handed screws overlap 8. backpitch covers among the figure
The specific embodiment
Known that by Fig. 1, Fig. 2 material enters from the enterprising material mouth of casing (1), carry through defeated material spiral (6) that enter first section positive and negative screw casing (7), (8) formation higher-pressure region, material is subjected to shearing and extruding at this, fiber begins to separate, discongest; Material is continued forward to carry by the fluting on the backpitch cover (8), enters second, third section higher-pressure region, starches at last by discharging opening (5) and exports.
Claims (2)
1, a kind of pulper comprises that motor, distributor box form, and it is characterized in that: two be engaged with each other, propellers parallel, that rotate in the same way, propellers are made up of with the backpitch cover defeated material spiral part, right-handed screw cover.
2, pulper according to claim 1 is characterized in that the pitch of right-handed screw cover forms the taper from large to small.
