Chemical Industry Cast Iron Filter Press is simply a kind of machine, which performs Filtration & separation during its Press operation. A Filter Press consists of a series of chambers containing square or rectangular filter plates supported in a frame. Once the filter chambers are loaded with slurry, the plates are forced together with hydraulic rams that generate pressures typically in the region of 100 pounds per square inch (70,000kg per m2). For comparison, a car tyre would be inflated to around 30 pounds per square inch. Each plate is covered by a material or membrane that acts as the initial filter when the press is in operation. As the solid filter cake builds up, the cake adds to the removal of fine particles. The solution coming through the filter, called the filtrate, will be very pure. If it is not wanted the filtrate can be drained away for safe disposal. At the end of the compression, the solid filter cake can be removed. The whole process is often computer controlled to make it automatic or semi-automatic.

Chemical Industry Cast Iron Filter press Structure and operating principle
1. Filter press consist of frame ,Filter Plate ,pressing system(manual , mechanical or hydraulic ) and electric control cabinet .
2. Frame consists of base , push plate and girder and supports the pressing device and filter plates .
3. Filter plates are installed on girder between tail plate and push plate , with Filter Cloth sandwiched in them.
In operation , the pressing device(cylinder piston rod or screw ) drives the push plate to press the filter plates and filter cloth between push plate and tail plate . Filter chambers are formed between pressed filter plates and material get in to The filter chambers through the feeding port in tail plate . Solid particles are trapped in filter chambers form into cakes , while liquid is discharged out of the tail Plate . In similar manner ,to drying the press cakes , compressed air can be introduced through the washing port .
4. Plate and frame type filter-Press is the same as Recessed Plate Filter Press in structure ,except the filtering part that consists of one plate , one frame and filter cloth ,with filter chamber between plate and frame.
5. Liquid stream of filter press can be divided into exeternal stream and internal stream . exeternal streamrefers to that the filtrate is discharged directly from outlet port of filter plate; internal stream refers to that the filtrate from various filter plate is collected before being discharged out of the filtrate port .
