Abstract

The invention discloses a deep dehydration pressure filtration device. The deep dehydration pressure filtration device comprises a main rack, a plurality of membrane filtration plates and non-membrane filtration plates. The main rack comprises two main beam plates which are oppositely and vertically arranged, the membrane filtration plates and the non-membrane filtration plates are arranged between the two main beam plates in an alternate and sliding mode, a thrust plate used for blocking the membrane filtration plates and the non-membrane filtration plates is fixed to one ends of the main beam plates, and a push mechanism used for pushing the membrane filtration plates and the non-membrane filtration plates to move towards the thrust plate is arranged at the other ends of the main beam plates; concave-arc-shaped or bent containing parts are arranged on the two side faces of the membrane filtration plates and / or the non-membrane filtration plates, and the two side faces of the membrane filtration plates are covered with elastic membranes. The deep dehydration pressure filtration device has the advantages that it can be avoided that water pressure causes stress concentration to the membranes, membrane connecting points are damaged, and consequently the filtration plates are damaged.

Description

technical field [0001] The invention relates to the field of sludge treatment industrial equipment manufacturing, more specifically, it relates to a deep dehydration filter press device. Background technique [0002] In sludge treatment, plate and frame filter press, diaphragm filter press and other equipment are usually used to separate solid-liquid from sludge with high water content. The existing diaphragm filter press presses the diaphragm and the filter plate together to make a diaphragm filter plate for use. When a certain pressure of water flow or air flow is input between the diaphragm and the filter plate to make the diaphragm bulge and press the filter cake, the connection between the diaphragm and the middle feeding boss of the filter plate, and the connection between the diaphragm and the frame of the filter plate will be subject to greater pressure. High pressure, easy to damage, once damaged, the whole filter plate will be scrapped. [0003] The frame of the ...
