Cast Iron Filter Press

Cast iron filter press is made of high quality cast iron or spheroidal graphite cast iron. It is suitable for high temperature material filtering, it has high filter plate strength, high filtration pressure and long life length. It is widely used in the separation of solid and liquid in petrochemical, metallurgical, oil and ceramic industries. The iron plate and frame filter press is divided into plate frame type and box type. The compression methods include the hydraulic press plate frame type iron filter press, the manual press plate frame type cast iron filter press, the mechanical press plate frame type cast iron filter press, the hydraulic press type cast iron filter press, the automatic drawing plate hydraulic press pressure filter press, and so on. Its model includes the type of 320, 450, 630, 800, the filter area is from 1 square to 120 square. The amount of processing is from 1L to 1200L.

The structure and working principle of the cast iron filter press:

1. The filter press is made up of frame, filter plate, compressing system and electric control cabinet.

2. The rack part plays the role of supporting the pressing device and the filter plate, and is composed of a frame, a pressing plate, a thrust plate and a main beam.

3. The filter plate is installed on the main beam between the compression plate and the thrust plate, and the filter cloth is sandwiched between them.

4. When it works, the pressing plate is pushed up by the pressing device, the filter plate and filter cloth are pressed tightly between the press plate and the thrust plate. The filter chamber is formed between the pressed filter plate and the filter plate. The material pressed into the material pump enters the filter chamber from the feeding inlet, and the solid particles are intercepted in the filter chamber, and the filter cake is formed and the liquid is filtered through the filter. The cake and filter cloth are discharged from the outlet of the liquid hole. If need to wash the filter cake, we can use the washing port on the tailboard to wash the filter cake to clean the filter cake. If we want to dry the filter cake, we can pass the compressed air into the washing port and blow the cake until it is dry.
