BELT FILTER PRESS


 

 

details


 

Filter press is a mechanical force applied to the side of the filter media to achieve filtering machinery,mainly used for solid - liquid separation of sludge (water).The sludge filter press is mainly used in the industrial sludge dewatering of paper making, starch, alcohol, vitamin C engineering and other industries.
一?/FONT>Working principle
     Watery sludge,transported by sludge pump to sludge mixing tank,At the same time, the coagulant is fully mixed, and then it flows into the belt sludge press, and the sludge is evenly distributed to the gravity dehydration area. Under the two-way dredging and gravity action of the mud rake, the sludge will quickly remove the free water of the sludge as the dehydration filter belt moves. Due to the long design of gravity dewatering zone, maximum gravity dewatering can be achieved. Flip down into long cuneate preloading sludge dewatering area will gravity unload sludge slowly clamp, sandwiching the layer Angle, order to slowly increase the pressure filter, minimizing the residual free water in the mud, with inched up and down two filters, up and down the distance between two belt has shrunk, in the middle of the mud gradually hardens, filtering by preloading dehydration of large diameter roller, and will take off a lot of free water to form mud cake.

Sludge filter press enter squeeze dewatering area, enter the "S" press section, in the "S" type of press section, sludge was caught in the middle of the upper and lower two layers of filter cloth, through a number of press roll press repeatedly, up and down two filters after alternating with the waveform of roll forming paths, with alternating fluctuation position of two belt of filter order, for clamping the mud cake of shear force, for the most part the residual moisture present in the sludge from the backlog filter, prompting mud cake dehydration, again finally, blow dry cake knife fall, no shaft by the belt conveyor or screw conveyor chance to sludge storage site.
二?/FONT>Characteristics

1. The filter belt will automatically tighten and correct the deviation, and the problem of damaged filter belt will be solved thoroughly. The electric control system is equipped with a chain protection device to ensure the safety and reliability of the whole machine.


2. Adopt a variety of antiseptic means antiseptic, the service life is long;

3.Super long design of triple dehydration zone, high dehydration rate, high solidity rate of mud cake; 

4. Simple principle, unified parts, easy management, easy maintenance; 
5. Smooth operation, low noise, low dosage of chemical agents;   
6?Fast speed, fast correction deviation, large output
三?/FONT> Application
    The belt filter press is suitable for sludge dewatering in wastewater treatment process of urban sewage treatment plant, pharmaceutical, electroplating, papermaking, leather, printing and dyeing, metallurgy, chemical industry, slaughtering, food, wine making and environmental protection engineering. It can also be applied to solid - liquid separation or liquid leaching in industrial production. It is widely used in domestic environmental engineering projects.
