Introduction
DY series automatic belt press Filter is the new product researched by our company and the national research institutes on the basis of foreign advanced filtering technologies.it is widely used in urban waste water treatment,chemical industry,oil refining,metallurgy,paper making ,leather ,food factory,coal washing ,printing and dyeing industry,sludge dewatering etc.It has the advantages :
(1) Automatic control and continuous working
(2) Low energy cost and long service life
(3) High dewatering efficiency and high solid containing rate of mud cake
(4) Easy maintenance and management
(5) Low noise and less chemicals
(6) Economical and reliable, wide application
There are three dewatering zone of the belt filter.The evenly spreaded filtering Material on the filter cloth firstly go in the first dewater zone—self gravity zone,above 50% water flow down after the process of adding flocculants(usually PFS or PAC),then the sludge was conveyed to the second dewater zone at the header side of the belt filter—cuneate zone.In this zone,the distrance between the unpper and lower belt becomes narrower and narrower progressively,the sludge was dewatered by the pressing of the belt.After that,the sludge goes into the third dewater zone—squeeze zone,in this zone,the sludge was squeezed by the pressure of small diameter roller and move like wave,after this zone,the filter cake was taken to the drawing knife and was shaving to the ground or collecting pool.
The tension of filter belt can be achieved through the air cylinder and keep in a constant. And the tension would not change with the inlet. It’s easy to operate and control. The press is equipped with the air compressor control system which can automatically correct and detect belt’s position on press role. For the belt press with a wider belt, there is an automatic sludge-in device which ensures the sludge can enter into the belt evenly, so as to improve the effect and lengthen the service life.
