Description

A multifunctional filter press

technical field

The utility model relates to the technical field of sewage treatment equipment, in particular to a multifunctional filter press.

Background technique

The filter press uses a special filter medium to exert a certain pressure on the object to make the liquid dialyze out of a mechanical device. It is a commonly used solid-liquid separation equipment. It was used in chemical production in the early 18th century and is still Widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries.

The plate and frame filter press is the first machine used in chemical dehydration. Although the plate and frame filter press is generally operated intermittently, the investment in infrastructure equipment is large, and the filtration capacity is also low, due to its large filtration driving force, high solid content of the filter cake, clear filtrate, high solid recovery rate, and conditioning drugs The advantages of low consumption and other advantages are still widely used in some small sewage plants. After the sludge is concentrated and digested, there is still a moisture content of about 95% to 97%, and the volume is still large. Sludge dewatering can further remove void water and capillary water in the sludge and reduce its volume. After dehydration treatment, the moisture content of sludge can be reduced to 70% to 80%, and its volume is 1/10 to 1/4 of the original volume, which is conducive to subsequent transportation and treatment. The dehydration process is composed of plates and frames arranged alternately. The two sides of the filter plate are covered with filter cloth, and the plate and the frame are pressed by a pressing device, that is, a filter press chamber is formed between the plate and the frame. There is a small hole in the middle of the upper end of the plate and the frame. After pressing, it becomes a channel. The sludge pressurized to 0.2-0.4MPa enters the filter press chamber through the channel. The surface of the filter plate is engraved with grooves. There are holes for the filtrate to be discharged. Under the pressure, the filtrate is discharged through the filter cloth, along the grooves and holes, and the sludge is dehydrated. Although the plate and frame filter press is generally operated intermittently, the investment in infrastructure equipment is large, and the filtration capacity is also low, due to its large filtration driving force, high solid content of the filter cake, clear filtrate, high solid recovery rate, and conditioning drugs The advantages of high consumption are still widely used in some small sewage plants.
