1, the properties and USES
) belt type filter press is my company on the basis of digesting and absorbing foreign advanced technology developed by a new type of efficient sludge treatment equipment, it has high efficiency, low energy consumption, good dewatering effect, simple structure, easy maintenance, low noise, smooth operation, safe and reliable, continuous automatic production advantages.Now it is widely used in petroleum, chemical, coal, metallurgy, building materials, textile, food and water environmental protection and other projects on the solid-liquid separation.
Sludge belt type filter press is on the basis of the original belt press filter increased concentration, sludge thickener including condensed sections, dehydration, sludge mixed reaction system, can be directly to the second pond sludge moisture content (99.2 99.6%) for enrichment dehydration, eliminating the traditional concentrated tank, saving a large amount of investment.
Belt type filter press is a kind of concentrated in the processing of materials (95-98% moisture content) further dehydration effective equipment into a pancake, with continuous automatic production, equipment installation, the characteristics of low cost of production and can be replaced with different mesh filter, continuous stepless speed regulation, so as to adapt to different kinds of materials of solid-liquid separation.The machine has reasonable structure, prevent water splashing, roll system installation precision is high, the partial less, extend the filter belt, bearings, and the service life of pneumatic components, main transmission adopts motor stepless speed regulation, increase speed range, stable operation, wash water front increased cleaning brush, improve the effect of the filter belt washing, reduces the rinse water, increases the rate of sludge dewatering.

Belt type filter press can be divided into three basic stages: in the whole process of sludge flocculation, filter press gravity dehydration, squeeze dewatering.
Sludge flocculation
Before sludge dehydration must go through the flocculation process and flocculation refers to using a flocculant (i.e., a kind of polymer, polymer electrolytes) was carried out on the suspension to processing, flocculating agent mixed with sludge classics agitate, cause solid phase particles in the suspension system of bonding produces condensation phenomenon, make the solid phase liquid phase separation.Sludge flocculation is in the process of flocculation reactor and sludge residence time in the flocculation reactor about 1 to 3 min.
Gravity dehydration

Approved by flocculation in the sludge moisture content 99.3% the thickener gravity dehydration, sludge moisture content of up to 95-98%, in order to reduce the liquidity of sludge before squeezing must emerge more free water and gravity dehydration is to achieve this function, the sludge in the filter belt is not affected by external forces, belt sludge load on the operation period of a dip, mud and water and filter with different friction coefficient, mud with the belt drive up line, water down, sludge has a process of accumulation, relative to extend the time of the gravity dehydration, emerge in favour of free water.Sludge through a reverse return to squeeze the filter belt, before getting into two filters clamping press, in a single filter with random running, its role is to make the sludge evacuation, evenly distributed on the surface filter with further dehydration.
Squeeze dewatering
Gravity sludge dewatering, up and down with the moving of the belt into the filter with the wedge between the pressure and get to the compression dewatering, and remove part of the free water on the surface of the sludge, and then enter the composed of seven roller "S" shape pressing section, due to the sludge as the filter with multiple stick between variable to bending shear stress, so as to extract the internal free water.
