Structure principle and application of filter press

The panel type and the plate and frame type filter press are both pressure intermittent operation filter equipment. The feed pump enters the suspension into each filter chamber of the filter press. Under the action of pressure, the liquid phase in the suspension flows out through the filter cloth. The solid phase is trapped on the filter cloth to form filter cake, and the filter plate can be released by loosening. Wash the filter cloth and press the filter plate to start filtering again.

Use of filter press:

The panel type and plate and frame type filter press is suitable for the separation and dehydration of difficult to separate materials with large filtration capacity, fine particle size and large viscosity. Widely used in petroleum, chemical, pharmaceutical, starch, sugar, food, beverage, mining, soap making, environmental protection and water treatment departments of all kinds of materials solid-liquid separation.

The structure of filter press:

Filter press is mainly composed of tail plate, filter frame, filter plate, head plate, main beam and pressing device. Two main beams connect the tail beam plate to the compacting device to form the frame. The frame is close to the head plate of the pressing device, and the filter plate and filter frame are arranged in turn between the head and tail plate, and the filter cloth is sandwiched between the plate and frame. The pressing way of filter press is divided into hydraulic, mechanical, jack and manual four, according to the flow way is divided into open current and undercurrent two. According to the filter cake washing method can be divided into washable and unwashable two. According to the plate frame material can be divided into reinforced polypropylene, rubber and cast iron three kinds. Users can choose according to the process and materials.
