The advantages of plate and frame filter press and drum filter press

Solid and liquid phase separation is the usage of machinery separated the solid particles difficult to disperse from the liquid, which is widely used in industrial production. The filter press equipment is an important equipment to complete the solid-liquid separation, with the social and modern industrial production continues to advance, filter press equipment has become indispensable equipment for food, pharmaceutical, mining, environmental protection and other industries.

According to the different ways of production pressure, filter equipment is divided into filter and suction filter two categories, such as plate and frame filter press, leaf filter, rotary vacuum filter and so on. Different filtration has different application, the environment and the nature of the material is differentiated, because the different processes and equipment properties mostly play a different role, these devices have their own advantages and disadvantages, Reasonable using equipment capacity can achieve better results.

Plate and frame filter press is composed of a plurality of filter plates and filter frames arranged alternately in a frame, and the number of filter plates and filter frames can be automatically adjusted within the frame length range, generally 10 to 60 blocks, filtering area is about 2 ~ 80m2. The four corners of the plate and the frame are opened with small holes. After assembling and stacking, the filter and the filtrate are respectively arranged in the channel of the filtrate, filtrate and washing liquid. Before the operation begins, by manual, electric and hydraulic drive to rotate the screw rod compression plate and box.

Plate filter press has the advantages of simple structure, large filtration area, high filtration pressure, flexible operation, easy to manufacture with corrosion-resistant material, and low water content of filter cake, and can be fully washed. Disadvantage is intermittent filtration, labor-intensive, suitable for small and medium-sized production and special requirements of the occasion.
Rotary vacuum filter, also known as Austria's filter, is a continuous filter. It is mainly composed of drum, filter cloth, metal mesh, agitator, rocking mixer, transmission, hand hole, filter room, scraper, distribution room, filter pipe and so on. The suction and filtration operations are carried out in a rotating cylinder. Generally in the pressure is less than 0.39MPa, air volume is less than 100m ³ / min under the operation.
