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. 4.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 . 5.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. 6.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 .
