Abstract

The utility model discloses a pulp light impurity cleaner, which comprises conic cleaner casing, the top part of which is provided with a feeding head which is provided with a spiral pulp inlet, and the inner wall of which is a V-shaped cone which is downwards extended into the inner cavity of the cleaner casing; the bottom of the cleaner casing is provided with a deslagging separating box which forms a barrel shape, the side wall of the deslagging separating box is provided with a good pulp outlet along the tangential direction and the center position of the bottom wall of the deslagging separating box is provided with a deslagging flow guiding pipe which is extended to the bottom of the inner cavity of the cleaner casing. The utility model has the advantages of simple structure, less power consumption, convenient installation, and low system maintenance cost; various light impurities in the pulp can be effectively removed.

Description

Paper pulp light impurity scummer

Technical field

The utility model relates to a kind of pulp processing equipment, especially a kind of paper pulp light impurity scummer.

Background technology

In short supply along with domestic pulpwood material, increasing pulping and paper-making factory uses waste paper pulp-making, but impurity is many especially in the waste paper, and especially removing of light impurity becomes the first-class problem that pulping and paper-making factory faces.At present light impurity removes hot dispersing modes and the pressurized screen modes of adopting more, but heat need to disperse power and heat energy, only can scatter light impurity, can not remove, the light especially impurity of proportion such as special picture wax, hot melt adhesive, after adopting heat to disperse, presenting on paper again to paper machine wax point when the overheated oven dry, only is than originally little; The present minimum of pressurized screen sieve seam only can be accomplished 0.15mm, utilize tiny sieve seam that impurity is removed, but the pressurized screen power consumption is big, and some tiny light impurities still can be sneaked in the paper pulp by the sieve seam, and it is low that light impurity is removed ability.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of simple in structure, power consumption is few, can effectively remove the paper pulp light impurity scummer of various light impurities.

For solving the problems of the technologies described above, the utility model comprises the hydrocyclone housing, its design feature is: the top at the scummer housing is equipped with feed head, and feed head is provided with the spiral stock inlet, and the feed head inwall is " V " shape cone that reaches down in the scummer housing inner chamber; In the bottom of scummer housing the deslagging Seperating box is installed, the deslagging Seperating box is round barrel shape, tangentially is provided with good slurry outlet on deslagging Seperating box sidewall, and deslagging Seperating box diapire centre is provided with the deslagging mozzle that extend into scummer housing intracavity bottom.

Described deslagging mozzle is fastened on the deslagging Seperating box by locking nut.

After adopting said structure, because slurry is close to inwall from the spiral stock inlet along hand of helix and is entered scummer, and form stable spiral by " V " shape cone that reaches down in the scummer housing inner chamber, slurry time of staying in scummer is longer, separation for light impurity is more thorough, because of light impurity proportion low weight, in with the slurry rotary course, gather the center gradually, from the deslagging mozzle, discharge, and slurry is because proportion is bigger, is thrown toward wall and discharges along the good slurry outlet of the tangential direction of slag Seperating box sidewall, the fibre stream vector reduces greatly, and it is simple in structure, power consumption is few, and is easy for installation, and the system maintenance expense is low.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A cross-sectional view of Fig. 1;

Fig. 3 is the B-B cross-sectional view of Fig. 1.

The specific embodiment

With reference to accompanying drawing, this paper pulp light impurity scummer has a hydrocyclone housing 3, at the top of scummer housing 3 feed head 2 is installed, feed head 2 is provided with spiral stock inlet 1, feed head 2 inwalls are for reaching " V " shape cone 7 in scummer housing 3 inner chambers down, and feed head 2 adopts with hydrocyclone housing 3 and is threaded; In the bottom of scummer housing 3 deslagging Seperating box 9 is installed, deslagging Seperating box 9 is round barrel shape, link together by big nut 6 between deslagging Seperating box 9 and the hydrocyclone housing 3, on deslagging Seperating box 9 sidewalls, tangentially be provided with good slurry outlet 4, deslagging Seperating box 9 diapire centres are provided with the deslagging mozzle 5 that extend into scummer housing 3 intracavity bottoms, and deslagging mozzle 5 is fastened on the deslagging Seperating box 9 by locking nut 8.
