Description

Expansion membrane pressing sludge or slurry filter plate

The present invention relates to a filter plate for inflating a diaphragm press sludge or slurry, especially a filter plate which can be applied to a filter press, and stacked with a plurality of filter plates to filter sludge or slurry. Dewatering, and injecting a pressurized fluid to produce a diaphragm expansion effect, and the sludge or slurry is subjected to a re-pressing dewatering filter plate.

According to the sludge, the business waste or slurry is a business product. The sludge disposal or slurry product utilization must comply with the law or the company's production specifications. In particular, the sludge is dewatered by filtration into a mud cake that is easier to transport and handle. The type of dewatering equipment can be divided into a round vacuum filter, a belt type, a centrifugal type dewatering machine and a plate type filter press. In particular, the plate cake press dewatering mud cake has a low moisture content, the sludge dewatering operation is easy, and the dewatering does not occur. Stench and reduce the cost of transportation and terminal burying and curing.

Sub-press, the main technical feature of the plate filter press is that a plurality of filter plates overlap and lean, and the feed is continuously fed to the filter plate filter chamber through sludge or slurry, and the filter plate is provided with a filtrate inlet and outlet on the side, when externally added When the pressure fluid is supplied to the pressure plate of the filter plate, the diaphragm on both sides of the filter plate is expanded to press the sludge or slurry to become a mud cake or a business product, thereby achieving the effect of solid-liquid separation.

However, it is necessary to quickly supply and discharge pressurized fluid on both sides of the filter plate. The fluid in the press process must have a relatively fast flow rate, but the fluid is easily restricted by the elastic membrane adhesion core inlet, resulting in secondary pressurization. The slow fluid inflow rate will cause the diaphragm on both sides of the filter plate to expand and press the sludge again.
