As the latest generation of white water recovery and pulp thickening equipment, this product can save energy, reduce water consumption and fiber loss, while protect the environment and prevent pollution.It is mainly suitable for white water recovery in paper mills, and its performance is superior and meets advanced national standards.
In the white water recovery process, the fiber recovery rate is high, water circulation is achieved,water consumption is reduced, and white water pollution is prevented.
The fan-shaped plate has excellent structure with high strength, easy disassembly, large effective filtration area and good filtration effect.
The equipment products have complete specifications and various diameters, and filtration area can be changed according to different production requirements.
The adjustable distribution valve made of special wear-resistant material has good sealing effect.The composite sealing tape can provide the maximum sealing effect.
Compact structure, small area occupied and high yield.
Good economic and social benefits.
Disc Vacuum Filter Structure And Principle
The disc vacuum filter mainly consists of the following parts: tank body, main shaft, filter disc, distribution valve, etc. The tank body can accommodate materials and maintain a stable liquid level. The filter disc function is filter pulp. The distribution valve is connected to the main shaft which purpose is to achieve different functions of each partition during the filtration process.
Disc vacuum filter uses vacuum as the power for filtration, recycling fibers and fillers.
When the main shaft drives the filter disc to rotate below the liquid level, the fan-shaped plate enters the atmospheric filtration zone, and the liquid in the tank passes through the filter screen under static pressure and is discharged through the outlet of the atmospheric filtration zone of the main shaft and distribution valve.
