Description
Technical field
The present invention relates to paper surface-sizing sizing material purification techniques field more particularly to a kind of paper surface-sizing starch
The cleaning equipment of sizing material.
Background technique
In modern paper mill, (physical strength of paper, anti-scratch performance, durable can be improved in paper and paperboard surface sizing
Performance, handling property and paper smoothness, moreover it is possible to the defects of overcoming paper fluffing, picking) it is indispensable a part.For
Use waste paper as the factory of primary raw material, due to using raw material excessively poor, ash content and other impurity phases in paper making pulp are worked as
Height, this easily causes paper when manufacturing paper with pulp by pull-up and linting when sizing applicator, especially in boxboard during manufacturing paper with pulp, due to
The fiber hair of page surface can gradually accumulate in the amylopectin of surface in the amylopectin cyclic process of surface, make surface amylopectin
Concentration increases by 1 times or more, directly affects glue-applying technique and the further physical index for influencing boxboard in paper-making process.Due to
The limitation of fund, technology etc., there is no mature techniques at present to handle the problem of surface glue starch concentration increases,
It can only be by constantly supplementing fresh amylan and the discharge great amylan of concentration come the problem of alleviating sizing material retrogradation, in this way
Paper surface can be made to generate the uneven phenomenon of sizing again, can not fundamentally solve the production problem, give paper pulp papermaking enterprise band
Carry out very big puzzlement.
In order to alleviate the problem of surface amylopectin becomes viscous, the measure mainly taken is that starch is actively discharged in paper mill at present
Part glue in glue tank, and add fresh glue and alleviate, some producers have also sought otherwise technology but can not all solve
The certainly problem, is primarily present following problems:
(1) using screening principle, the fiber hair in the amylopectin of surface is removed using multistage sieve, though this method can remove
A part of fiber hair, but fiber hair can not be removed at all using slotted screen, still can some fiber hair stay in surface amylopectin
In；
(2) surface glue is passed through sand cleaning machine, it is intended to use the side of centrifugation by the method for using sand cleaning machine class in whole flow process
Method removes fiber hair, but this method can only remove the big substance of density ratio starch glue, such as sandstone, hard impurity, base
Originally it not can be removed fiber hair, still can not solve the problems, such as amylan retrogradation；
(3) surface glue is passed through pressurized screen by the mode for using pressurized screen on stream, but pressurized screen itself be slotted screen or
Person's hole sizer, while amylan passes through, fiber hair can also pass through, so the impurity such as some small grains of sand can only be removed, can not incite somebody to action
Fiber hair removes.
Therefore, at present in entire paper industry sizing material field of purification, need to surface sizing starch sizing material cleaning equipment into
Row improves to solve the problems, such as fiber hair.
Summary of the invention
In order to solve that papermaking surface amylopectin can not be solved in the prior art during recycling due to the fibre of paper
Dimension hair and hard impurity fall into surface glue the problem of making glue retrogradation to influence production, and the object of the present invention is to provide one kind to make
The cleaning equipment of paper top sizing starch sizing, which is added in paper-making sizing process, to solve sizing material
In the problem of causing sizing material to thicken constantly accumulated due to fiber hair, while improving the mobility of surface amylopectin, make sizing more
Uniformly, the quality of paper is further increased.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
