DY type belt filter press is widely used in sludge mechanical dewatering, which has the advantages of continuous production, low power consumption, large processing capacity and convenient operation and maintenance. This machine is equipped with long gravity dehydration zone, wedge dehydration zone, pre-press dehydration zone, extrusion dehydration zone and other dehydration systems. First, the free water and the sludge are fully separated, and then the sludge is gradually dehydrated under pressure, so that the sludge can achieve a better dewatering effect. This machine adopts a pneumatic system to automatically adjust the deviation and synchronously tighten the filter belt. The speed of the filter belt is steplessly adjustable. The material is polyester monofilament, with plain weave and spiral mesh, etc. The device is functioning normally. The whole machine is a semi-closed box structure, and the material is treated with special anti-corrosion treatment. It has the advantages of reasonable structure, beautiful appearance and long service life.
The system includes the host, flocculation reactor, chemical liquid mixer, chemical liquid quantitative pump, sludge variable pump, cleaning water pump, air compressor, belt conveyor or screw conveyor, centralized control box, etc. It can realize flocculation, dosing, sludge transportation, filter belt cleaning and automatic control in the process of sludge dewatering.
Scope of use
It is mainly used for sludge dewatering in water supply and drainage projects to reduce its volume, which is conducive to further landfill, incineration and other treatment occasions.
