Process flow of mine sludge dewatering equipment exported to the United States
The ZYL belt filter press produced by our company is a water treatment equipment that has been successfully developed by introducing advanced technology from the United States and digesting and absorbing it. It can continuously filter large amounts of sludge. The product is made of high-strength materials and has significant characteristics such as high processing capacity, high dehydration efficiency, and long service life. It is widely used in environmental governance in various industries. The bearings equipped with it have a long service life and use high-quality filter belts from around the world, Fully ensure the performance and quality of the filter press. At present, this product has been sold worldwide.
ZYL belt filter press is an environmentally friendly solid-liquid separation equipment that can concentrate or digest the mixed liquid into sludge, reduce or remove moisture, and convert it into semi-solid or solid sludge cakes.
ZYL Belt filter press process flow:
1. Gravity dehydration:
The sludge from the wastewater treatment plant is pumped into the sludge mixing tank and mixed with polymer, causing small suspended particles in the sludge to form larger particles in the form of flocs through the bridging effect of polymer coagulants. Then, it overflows into the automatic discharge device of the dewatering machine through the upper end of the mixing tank in a gravity flow manner, making the floc sludge evenly distributed on the filter cloth in the gravity dewatering zone.
The function of the gravity concentration and dehydration zone is to allow most of the free water outside the gel feather sludge to be discharged by gravity through the mesh of the filter cloth, in order to increase the sludge concentration and stabilize the characteristics of the gel feather sludge, and to utilize subsequent pressing and dehydration operations.
2. Pressure dehydration:
After the sludge enters the pressure dehydration zone from the gravity dehydration zone, the upper and lower filter cloth gradually presses and compresses the sludge for dehydration.
3. Pressurized dehydration area:
The sludge moves with the filter cloth and enters the pressurized dewatering zone. Between the vertical rollers, the diameter of the rollers decreases gradually, and the pressure increases gradually. With the shear force generated by the upper and lower filter cloth changing the position of the filter cloth between different rollers, the capillaries in the adhesive sludge are squeezed out by combining water (Capillary Water) to produce a drier sludge cake.
