Description
Technical field
The present invention relates to paper-making pulping purification apparatus technical fields, particularly relate to a kind of novel light impurity slagging-off dress
It sets.
Background technology
Scummer the '20s are just applied to paper industry, have been widely applied since nineteen fifty.At present in waste paper system
In sizing process, scummer is indispensable part in whole system.Scummer by the impurity of removing can be divided into heavy scummer,
Light dregs-removing device and multi-functional scummer.The raw material of current waste paper pulp-making is entirely the waste paper recycled, both contained in waste paper sand,
The relatively large heavy seeds of the proportions such as dust also contain the light impurities such as plastic sheet, wax, foam, the at present slagging-off of heavy scummer
Effect is very good, but the processing of light impurity is always a great problem of domestic paper-making industry, and existing light dregs-removing device separation is not
Thoroughly, slagging-off effect is poor, and fiber loss amount is big, and is generally no greater than 0.5% into slurry concentration, causes great lot of water resources and power wave
Take, seriously affects the quality of the especially high-grade paper of paper.With the development of industry, the gummed paper in regenerated paper pulp, plastic film coated etc.
Impurity increases significantly, and difficulty is brought to impurity separation.
Invention content
The present invention proposes a kind of novel light impurity deslagging device, solves scummer separation in the prior art and is not thorough, removes
The problem of slag effect difference.
The technical proposal of the invention is realized in this way：Novel light impurity deslagging device, including：
Slagging-off pipe, slagging-off pipe be cylindric and be vertically arranged, and the upper end of the slagging-off pipe with its equipped with tangent being connected to
Inlet pipe；
Good slurry pipe, the good slurry pipe stretch into the inner cavity of the slagging-off pipe from top to bottom, the upper end of the good slurry pipe be equipped with
It is connected to, the good slurry of horizontal direction exports；
Light slag collecting pipe, the light slag collecting pipe are located inside the good slurry pipe, the upper end outlet of the light slag collecting pipe
Higher than the upper end of the good slurry pipe, the inner cavity of the slagging-off pipe is also stretched into the lower end of the light slag collecting pipe；
The slagging-off pipe, good slurry pipe and light slag collecting pipe are coaxially disposed, and annular region is formed between adjacent two pipelines.
As a preferred embodiment, the lower end of the slagging-off pipe is also communicated with middle node, lower cone and flushing water
Device.
As another preferred embodiment, the top and bottom position of the good slurry pipe is equipped with position at its center
The nut set, the light slag collecting pipe and the nut screw-thread fit.
As another preferred embodiment, underlying nut is solid by three uniformly distributed supporting rods of circumferencial direction
Due on the inner wall of the good slurry pipe.
As another preferred embodiment, the light slag collecting pipe is stainless steel tube.
After using above-mentioned technical proposal, the beneficial effects of the invention are as follows：When system enters slagging-off to starch by inlet pipe
Vortex is initially formed when pipe, due to the effect of inertia force, the heavier impurity of proportion starts to move to periphery in slurry, and proportion is smaller
Impurity it is mobile to centre, to form three annular regions, wherein the impurity of most peripheral is moved downwardly into subsequent place
Science and engineering sequence, and the good slurry positioned at intermediate region is managed by good slurry, good slurry outlet discharge, the light impurity positioned at most inner region passes through
Light slag collecting pipe discharge, the deslagging device of this structure is not while changing scummer heavy seeds slagging-off efficiency, and fully solution
The difficult problem of scummer light impurity of having determined separation, has good practicability.
Light slag collecting pipe is fixed on to the centre position of good slurry pipe by screw-thread fit can prevent scarfing cinder collecting pipe from occurring
Dancing, and then influence its effect that removes the gred.
The nut of lower section is fixed on the inner wall of good slurry pipe and can further be carried by three circumferentially uniformly distributed supporting rods
The fastness of high light slag collecting pipe.
Scarfing cinder collecting pipe has preferable wearability using stainless steel tube, can effectively extend the use of entire deslagging device
Time limit reduces the maintenance cost of equipment.
