Description

High-pressure cleaning plate-and-frame filter press

Technical Field

The utility model relates to a plate and frame filter press technical field, especially a high-pressure cleaning plate and frame filter press.

Background

In industrial production, feed liquid generated in the production process is often filtered, so that the aim of solid-liquid separation is fulfilled; the plate-and-frame filter press is a solid-liquid separation device with wide application, is an intermittent solid-liquid separation device, and is mainly characterized in that a filter press set is pressurized by a hydraulic device, feed liquid is fed into each filter chamber, and solid and liquid are separated by a filter medium; compared with other solid-liquid separation devices such as a centrifugal machine and the like, the plate-and-frame filter press has the advantages of low investment, electricity saving, safety and the like.

The filter plate is a main filter element arranged on the filter press, materials are trapped by a filter medium to form filter cakes in the filter plate, and filtrate enters the four-corner holes through a liquid outlet channel formed by bosses or grooves in the filter plate and is discharged, so that the aim of solid-liquid separation is fulfilled; in the prior art, fine particles can penetrate through filter cloth and stick to a liquid outlet channel of a filter plate due to impact of feeding pressure when materials are filtered, the penetration filtering phenomenon enables the particles in the materials to stay and accumulate gradually in the liquid outlet channel formed by a boss or a groove in the filter plate, deposited fine particle block filter cakes stick to the boss or the groove, and the liquid outlet channel of the filter plate is blocked, particularly, the materials in the chemical industry contain viscosity and the fine particles block the liquid outlet channel seriously, so that the liquid drainage of the filter plate of the filter press is difficult, the filtering efficiency is low, the production cost is high, and the production benefit is directly influenced.
