Abstract
The utility model relates to the technical field of pulping and papermaking, in particular to a vacuum suction type dehydration device on a multi-roller filter press. The device consists of a motor, a vacuum pump and vacuum water suction boxes, and is characterized in that: 1 to 3 vacuum water suction boxes are fixed on the lower mesh surface of a lower spiral mesh of the multi-roller filter press, and are communicated with the vacuum pump driven by the motor. When the multi-roller filter press operates, pulp uniformly distributed in a pulp distributor flows through the vacuum water suction boxes before flowing into a squeezing area, and full width uniform dehydration is performed on the pulp between an upper spiral mesh and a lower spiral mesh through the vacuum water suction boxes, so that dehydration amount can be increased, the thickness of a pulp layer can be increased, the concentration of the pulp at the outlet of the multi-roller filter press can be improved, and the pulp flow amount of the multi-roller filter press can be improved.
Description
Affiliated technical field
The utility model relates to the pulp and paper technology field, the vacuum pumping-type dewater unit on specifically a kind of multiple roll filter press.
Background technology
At present, the multiple roll filter press of producing the semi-chemical pulp use in the pulping and paper-making field adopts pulp distributor equably slurry to be distributed on the spiral wire side, enter down the precompressed shove district of spiral net after filtration behind the pool, again through arriving pressed zone, pulp after squeezing behind the precompressed zone.But in service in actual production, multiple roll filter press pulp concentration is little, and slurry layer thin yielding poorly.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, vacuum pumping-type dewater unit on a kind of multiple roll filter press is provided, use this vacuum pumping-type dewater unit can be to being distributed in the slurry between spiral net and the following spiral net, before entering pressed zone, strengthen dehydrating amount, increase the slurry layer thickness, improve the concentration of multiple roll filter press outlet slurry, improve the slurry through amount of multiple roll filter press.
The technical scheme that its technical problem that solves the utility model adopts is: the vacuum pumping-type dewater unit on a kind of multiple roll filter press, form by motor, vavuum pump and suction flat box, it is characterized in that: wire side is fixed 1～3 suction flat box under spiral net under the multiple roll filter press, and suction flat box is communicated with the vavuum pump of driven by motor.
The beneficial effects of the utility model are, improve the concentration of multiple roll filter press outlet slurry, improve the slurry through amount of multiple roll filter press, and the concentration that reduces because of entering pressed zone is little, the slurry loss that the slurry layer can't be finalized the design and be caused by conquassation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A-A cut-away view of the present utility model.
1. motors among the figure, 2. vavuum pump, 3. suction flat box.
The specific embodiment
This vacuum pumping-type dewater unit is made up of motor 1, vavuum pump 2 and suction flat box 3, it is characterized in that: wire side is fixed 1～3 suction flat box 3 under spiral net under the multiple roll filter press, and suction flat box 3 is communicated with the vavuum pump 2 that motor 1 drives.
When the multiple roll filter press moves, from the equally distributed slurry of pulp distributor before entering pressed zone, by suction flat box 3,3 pairs of slurries of going up between spiral net and the following spiral net of suction flat box carry out full width and evenly dewater, can strengthen dehydrating amount, increase the slurry layer thickness, improve the concentration of multiple roll filter press outlet slurry, improve the slurry through amount of multiple roll filter press.
