Product Description

Belt Pressure Filter

The belt press filter is mainly composed of a driving device, frame, press roller, upper filter belt, lower filter belt, filter belt tensioning device, filter belt cleaning device, and discharging device. gas control system. electrical control system. sludge is pumped into a dynamic (static) mixer, mixed with the anion (yang) ion flocculant solution added at the same time fully reacted, and then coagulated into a larger flocculent mass. The surface water of the material is separated into free water. The material is transported through the filter net of the first gravity pre-dewatering zone (or on the belt concentrator) and gravity is removed. Aftergravity dewatering, the fuidity of sludge becomes worse obviously, but it is still difficult to meet the requirement of sludge fluidity in the pressing dewatering section. Therefore, a wedge-shaped pre-pressing dewatering section is added between the pressing dewatering section and the gravity dewatering section of the sludge, and the sludge is dewatered by slight extrusion in this section. Removal of free water from its surface almost completely loses its fluidity, which ensures that sludge will not be extruded in the pressing dewatering section under normal conditions, creating conditions for smooth pressing dewatering.
 

Technological Process

1. Sludge flocculation

 

In order to improve the dewatering of sludge, improve the nature of the filter cake and increase the permeability of the material, it is necessary to carry out chemical treatment on the sludge, this machine uses the unique device of "flocculation granulation mixer in water" in order to achieve the effect of chemical dosing flocculation, this method not only has good flocculation effect but also saves a large number of pharmaceuticals, with low operating costs and very obvious economic benefits.

 

2. Gravity concentration and dewatering area
 

The sludge is evenly fed into the mesh belt through the fabric hopper, the sludge runs forward with the filter belt, and the free water flows into the receiving tank through the sincere belt under the action of self-weight, the gravity dewatering can also be said to be the highly concentrated section, and the main function is to take off the free water in the sludge, so that the mobility of the sludge is reduced, and to make preparation for further extrusion.

 

3. Low-pressure/medium-pressure dewatering zone
 

After gravity and dewatering, the sludge mobility is almost completely lost. With the forward running of the filter belt, the sludge is brought into the porous roller by the wedge zone, the spacing between the upper and lower filter belts is gradually reduced, the filtrate starts to overflow from the two sides of the filter belt, and with the running of the filter belt, the pressure is gradually increased. As the belt runs, the pressure gradually increases. The function of the wedge zone is to prolong the gravity dewatering time, increase the extrusion stability of the flocs, and prepare for entering the pressure zone.
 

4. To the pressure silver (or with) high-pressure dehydration area

The sludge enters the high-pressure zone after leaving the medium-pressure zone, forming the filter cake with high solid content. Material from the wedge-shaped area into the pressure area, the material in this area by the extrusion, along the running direction of the belt pressure with the reduction of the diameter of the extrusion of the clip and increase the volume of the material by the extrusion of contraction, the sludge in this area by the 1-3 groups of pairs of pinch rollers (or belt) extrusion, after strong extrusion of the volume of the substantial contraction of the sludge within the gap of the free water is fully squeezed out to form a cake, and continue to go forward to the end of the high pressure zone after the high-pressure After the high pressure, the water content of the filter cake can be minimized.
