Background

Pulp filtration, which is an important step in the papermaking process, is to separate pulp water into water and slurry by a filter device and collect the separated slurry. The pulp residue filtering device is an important device for filtering in the manufacturing process of base paper.

When the paper pulp is filtered, the raw paper is beaten into paper pulp in water and then enters a paper pulp filtering device for dehydration processing, so that more water is separated from the paper pulp. However, in pulp filtration, pulp tends to adhere to the filtration pores, which leads to clogging of the filtration pores and affects the separation efficiency, and for example, application No. CN201710995338.9 discloses "a pulp filtration apparatus", and the main contents thereof are: when the paper pulp filtering device works, paper pulp liquid enters from the feeding hole and flows through the buffer plate, the paper pulp liquid enters the paper pulp groove after being buffered by the buffer plate, the filter screen in the paper pulp groove separates water and paper pulp in the paper pulp liquid, and the water and the paper pulp are discharged from the water outlet and the discharge hole respectively and are collected.

However, the patent only can filter the pulp, and the shortage of the patent does not provide a good solution for the blocking phenomenon, so that the efficiency of the water separation of the pulp is relatively low.

1. Technical problem to be solved

Aiming at the problems in the prior art, the invention aims to provide a paper pulp filter residue plate with a micropore adjustable structure, compared with the prior art, the filter residue plate is made to be of a double-net-plate structure by adding a hole adjusting double net plate, when a blockage phenomenon occurs, a reversible self-separation plate below the hole adjusting double net plate holds part of downward-seeping water, the weight is increased, a downward-pulling force is generated on a moving comb plate, the effect of increasing the pores of the filter holes can be realized, the downward-seeping of water is accelerated, and the efficiency of water separation in paper pulp is obviously improved.

2. Technical scheme

In order to solve the above problems, the present invention adopts the following technical solutions.

A paper pulp filter residue board with a micropore adjustable structure is characterized in that on the basis of the prior art, a structure of a hole adjusting double net board is added on filter holes of a filter residue board body, the hole adjusting double net board comprises a plurality of hole adjusting rings respectively matched with the filter holes, a plurality of connecting rods connected between two adjacent hole adjusting rings, lower leading ropes connected in the hole adjusting rings and reversible self-separating sheets connected below the lower leading ropes, a plurality of movable comb sheets and fixed comb sheets which are uniformly distributed are fixedly connected in the hole adjusting rings, the fixed comb sheets are positioned below the movable comb sheets, so that the filter residue board has a double net board structure, when the paper pulp is filtered and separated, water seeps downwards in a part of the reversible self-separating sheets below the hole adjusting double net boards, the weight of the filter residue board is increased, the movable comb sheets generate downward pull force, the pores of the filter holes are increased, the downward seepage of water is accelerated, when the blockage phenomenon is serious, the water quantity contained in the reversible self-separation piece is too much, so that the reversible self-separation piece is disintegrated into a plurality of water diversion pieces, and the water diversion pieces swing along with the vibration on the filter screen during water separation, play a role in pulling and swinging the movable comb piece, and obviously improve the efficiency of water separation in paper pulp.

Further, decide the comb piece and be the stereoplasm structure, it is the elasticity slope structure to move the comb piece, and a plurality of one ends that move the comb piece and be close to each other are low, and when making and receive the power of dragging that comes from down the leader, the leader can deform down, leads to actuate the comb piece and decide the mutual space increase of comb piece, realizes the effect of adjusting the hole size.

Furthermore, a plurality of move the comb piece with decide the mutual interval distribution of comb piece in the footpath to when vertical a plurality of move the comb piece with decide the comb piece and cooperate each other and can play the effect of interception to the thick liquids in the paper pulp, effectively reduce the loss of separation moisture time to the thick liquids cause.

Furthermore, the end part of the lower guide rope in the hole adjusting ring is of a multi-branch structure, and the branches are fixedly connected with the movable comb pieces respectively, so that the connection stability between the lower guide rope and the movable comb pieces is high.

Furthermore, the reversible self-separation sheet comprises a plurality of water diversion sheets which are bonded with each other, and the lower guide ropes are fixedly connected with the middle parts of the water diversion sheets respectively.

Furthermore, the water diversion sheets are made of flexible light materials, so that the reversible self-separation sheet composed of the water diversion sheets has certain flexibility, when water is separated, the water seeps downwards to the reversible self-separation sheet, the reversible self-separation sheet can be wavy under the pulling of a lower guide rope, part of water is trapped, the pull force is generated on the movable comb sheet, the downward inclination amplitude of the comb sheet is increased, the filter hole is enlarged, the situation that the filter hole is blocked along with the extension of water filtering time is effectively prevented, the edges of the water diversion sheets are parallel and level with each other, and the water diversion sheets can be connected with each other to form the integral reversible self-separation sheet during pretreatment.

Furthermore, before the hole adjusting double-mesh-plate is installed on the filter plate, the water diversion sheet is folded and wrapped at the lower end part of the lower diversion rope, and the folded water diversion sheet is connected with the lower diversion rope through a water-soluble material, so that the lower diversion rope and the water diversion sheet are integrally strip-shaped, compared with a sheet-shaped structure after the water diversion sheet is unfolded, the hole adjusting double-mesh-plate is installed on the filter plate more conveniently, and the installation difficulty is reduced.

Furthermore, when the device is used, the plurality of strip-shaped lower guide ropes and the plurality of strip-shaped water diversion sheets on the hole adjusting double-mesh plate respectively penetrate through the filter holes, and then the hole adjusting rings are clamped into the filter holes, and then the device needs to be pretreated and put into use.
