Abstract

The invention relates to a corner membrane filter plate assembly which comprises the flat membrane filter plate and the filter cloth filter plate. Both the flat membrane filter plate and the filter cloth filter plate are single-corner feeding through holes and are arranged in cross banding. The corner membrane filter plate assembly has the advantages that: 1. portholes have self-cleaning function, thus being capable of keeping the portholes smooth without obstacles; 2. rapid filter of slurry is realized; 3. a filter cake can be convenient to be washed either in a forward direction or a reverse direction, therefore, the filtering ratio of effective components in filtered slurry is greatly increased, and a feeding pump and a washing pump can share a pump; 4. by adjusting the thickness of a core board, the requirements for the thickness of the filter cake from different materials can be met; 5. a supporting lug boss can be arranged on the membrane filter plate or no supporting lug boss is arranged on the membrane filter plate; 6. no filter cloth is installed on the flat membrane filter plate.

Description

technical field [0001] The invention relates to an angle-feed diaphragm filter plate assembly composed of a flat diaphragm filter plate and a filter cloth filter plate, which is mainly used for rapid filtration of slurry and belongs to the field of diaphragm filter plate manufacturing. Background technique [0002] Patent No. 01274970.2, name "filter cloth damage self-inspection device", filter cloth on the filter plate, the filtrate channel in the filter plate is connected with the liquid outlet of the filter plate, the side of the filter plate is opened with a shunt and drainage channel, the filter plate A side part of the liquid outlet is provided with a split liquid inlet channel, and the split liquid discharge channel and the split liquid inlet channel are connected by plastic transparent tubes. [0003] CN2522145, the name "composite polypropylene diaphragm filter plate", the composite polypropylene diaphragm filter plate is mainly composed of a core plate, a diaphragm...
