DZY belt press vacuum filter machine
Features：

Core advantages:Dual dehydration technology of vacuum filtration and mechanical pressing, first removing most of the free water through vacuum suction, and then extruding the capillary water through high-pressure rollers (line pressure ≥ 5MPa), resulting in a low moisture content of 18% -22% in the filter cake;;

Intelligent monitoring:Real time display of parameters such as vacuum degree, filter cake thickness, processing capacity, etc., supporting remote fault diagnosis;;

Applicable scenarios:Municipal sewage plant sludge dewatering (replacing traditional plate and frame filter presses), deep drying of high humidity chemical materials (such as dye filter cakes);;

Customer value:Sludge reduction rate of over 70%, significantly reducing subsequent incineration/landfill costs..

Introduction to DZY Belt Press Vacuum Filter

DZY Belt Press Vacuum Filter is a new type of highly automated filtration equipment that combines PBF series and DY series. The machine uses a filter belt as the filtration medium and fully utilizes the gravity of the material.; The high-efficiency separation equipment for solid-liquid separation is achieved by vacuum suction and squeezing pressure of the press roller, especially suitable for materials with a filter cake compression ratio greater than 2:1 (at 10Kpa), which can fully reduce the moisture content of the filter cake.


DZY Working principle of DZY belt press vacuum filter: At the beginning of the filtration stroke, the filter disc runs synchronously with the filter belt in a vacuum state. The material is evenly distributed on the filter belt of the vacuum filter disc through the slurry distributor and filtered under the action of vacuum suction. Subsequently, the semi dry filter cake continues to run under the drag of the filter cloth and enters the pressing roller for squeezing, fully reducing the moisture content of the filter cake. After filtering, washing, and squeezing, the filter cake is peeled off and removed by a scraper device, and the filter cloth is cleaned by a regeneration device before entering the next cycle again. The filtrate from the collection tank is discharged simultaneously with the return of the filter disc, and the filtrate from the squeezing roller flows into the collection disc. By repeatedly filtering, washing, filtering, and squeezing, the goal of solid-liquid separation is achieved.

DZY belt press vacuum filter selection guide:

1. Select the equipment model based on solid-liquid ratio, processing capacity, solid particle size, viscosity, and solid bulk density.

2、 Select the material of the overcurrent component based on the pH value of the material, and choose the filtering medium according to the solid particle size and material temperature.

3、 Suitable for materials with a filter cake compression ratio greater than 2:1 (at 10Kpa).

4、 The same materials that have not been used in the same industry should undergo small-scale testing before equipment selection.

5、 Prioritize selecting models with effective width filtering according to national standards.
