And (3) most of sewage in the paper-making sludge can be removed. So that the papermaking sludge slurry obtained in the step (4) is more neutral after water is added into the dewatered sludge again and then the sludge is stirred. When the dewatering assistant is added into the slurry, the sludge is easier to flocculate, and the dewatering efficiency of the sludge is increased.
The method for preparing the slurry in the step (4) ensures that the obtained gasket plate has high strength, and the slurry obtained by the method has good dehydration property.
In the step (4), the dehydration assistant comprises the following components in parts by weight: 20-40 parts of starch, 1-3 parts of cationic polyacrylamide and 20-50 parts of hexadecyl trimethyl ammonium bromide;
the dehydration auxiliary agent preferably comprises the following components in parts by weight: 30 parts of starch, 1 part of cationic polyacrylamide and 50 parts of hexadecyl trimethyl ammonium bromide.
In the step (4), the dehydration assistant may further include the following components in parts by weight: 20-40 parts of starch, 0.5-1 part of cationic polyacrylamide, 20-50 parts of hexadecyl trimethyl ammonium bromide and 10-20 parts of copper chloride;

As shown in fig. 1-6: the gasket plate forming device in the step (5) comprises a frame 1, a plurality of conveying rollers 2 arranged on the frame 1, a pulp suction blanket 3 wound on the conveying rollers 2 and driven to convey through the conveying rollers 2, a plurality of pulp suction mechanisms matched with the pulp suction blanket 3 to adsorb pulp fibers, a forming and thickness-fixing mechanism for adsorbing the pulp fibers on the pulp suction blanket 3, and a plurality of water absorption mechanisms for adsorbing water on the pulp suction blanket 3.
The pulp sucking mechanism comprises a pulp tank 4 for containing the pulp prepared in the step (4), a pulp sucking roller 5 which is arranged on the frame 1 and matched with the pulp tank 4 to adsorb pulp fibers, and an extrusion roller 6 which is arranged on the frame 1 and positioned above the pulp sucking roller 5; the pulp suction blanket 3 passes through the gap formed between the pulp suction roll 5 and the squeeze roll 6.
The lateral wall of the upper part of the slurry pool 4 is provided with a slurry outlet, and the slurry suction roller 5 is arranged at the slurry outlet.
The pulp suction roller 5 absorbs pulp fibers flowing out of a pulp outlet of the pulp tank 4 on the surface of the pulp suction roller while rotating; under the extrusion action of the extrusion roll 6, the pulp suction blanket 3 adheres pulp fibers on the surface of the pulp suction roll 5 to the surface of the pulp suction blanket.
And an adsorption layer 16 for adsorbing fibers in the slurry is coated on the periphery of the slurry suction roller 5. The absorbent layer 16 may be of a material similar to a felt.
The periphery of the squeezing roller 6 is coated with an elastic rubber layer 17. The rubber layer 17 coated on the periphery of the squeeze roll can enable the pulp fibers adsorbed on the pulp suction roll to be more thoroughly coated on the pulp suction blanket.

The pulp suction blanket 3 is subjected to the adsorption of the pulp fibers by the pulp suction mechanism, and then the collection roller 20 adsorbs the pulp fibers on the pulp suction blanket 3 while rotating. When the pulp fibers on the collecting roller 20 reach a certain thickness, the collecting roller 20 covered with the pulp fibers can drive the fixed-thickness roller 21 to rotate in the non-rotating state during the rotation process. Once the sizing roller 21 has rotated, indicating that the desired thickness of the pulp fibers on the collector roll 20 has been achieved, the mat sheet containing water has been initially formed, at which point the worker can tear off the initially formed mat sheet on the collector roll 20.

The spacer plate cutting member is an elastic thread 24 having both ends respectively fixed to both ends of the collecting roller 20.
The elastic thread 24 rotates together with the collecting roller 20, and the preliminarily formed pad sheet on the collecting roller 20 is covered on the elastic thread 24. When the thickness-fixing roller 21 starts to rotate, the worker rapidly stretches the elastic wire 24 outwards, so that the preliminarily formed gasket plate on the collecting roller 20 can be cut off, and then the preliminarily formed gasket plate is smoothly pulled off.
The water absorption mechanism comprises a water absorption box 25 with a water absorption plate 26 at the bottom and a water absorption pipe 28 which is communicated with the water absorption box 25 and is provided with a water pump 27; the water absorption plate 26 is provided with a plurality of water absorption holes 29, and the total through area of the water absorption holes 29 on the unit area of the water absorption plate 26 is gradually increased from the area close to the water absorption pipe 28 to the periphery.
As shown in fig. 1: at least one water absorption mechanism is arranged in front of the pulp absorption mechanism: before the pulp absorption blanket 3 enters the pulp absorption mechanism, the water absorption mechanism is required to absorb the water on the pulp absorption blanket 3, so that the pulp absorption blanket 3 can be favorably adhered to the pulp fibers on the surface of the pulp absorption roller 5;
the pulp suction blanket 3 passing through the pulp suction mechanism is provided with at least one water suction mechanism; the pulp absorption blanket 3 passing through the pulp absorption mechanism contains a large amount of water, and the water absorption mechanism is required to remove part of the water on the pulp absorption blanket 3 so as to facilitate the collection roller 20 to be adhered to the pulp fibers on the pulp absorption blanket 3, thereby being beneficial to the primary forming of the density board.
The suction box 25 of the water suction mechanism can be fixedly arranged on the frame 1, the suction plate 26 can be tightly attached to the pulp suction blanket 3, and after the water pump 27 is started, water on the pulp suction blanket 3 can enter from the suction hole 29 and finally be discharged from the suction pipe 28.
As shown in fig. 1: the section of the pulp suction blanket 3 provided with the water suction mechanism is preferably in a tensioned state to facilitate the water suction of the water suction mechanism.
The total through area of the water suction holes 29 on the unit area of the water suction plate 26 is gradually increased from the area close to the water suction pipe 28 to the periphery, so that the suction force of the water suction mechanism on each position of the pulp suction blanket 3 is basically the same, and the effect of uniform water suction is achieved.
In the step (5) of the invention, the high-dehydration-performance slurry obtained in the step (4) is prepared into the hydrous gasket plate with the water content of 40-50% by using a special gasket plate forming device.
