Problems solved by technology

At present, the plate and frame filter devices generally used in the municipal sludge industry are middle-feed filter plates and filter frames. Moreover, the middle-feed filter plates and filter frames have the following defects during use. The middle feed hole occupies an effective The pressure filter area affects the filtration efficiency. Sometimes the sludge has a high viscosity, and the upper corners of the feed will not be full when feeding, which affects the filtration speed and efficiency.
The surface of the metal plate frame is not treated, the sealing effect of the filter chamber is poor, and sometimes there will be mud leakage

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention will be further described:

[0026] refer to figure 1 , figure 2 , image 3 , the present invention provides an elastic press filter plate and filter plate assembly for electroosmotic high-pressure sludge with upper feeding;

[0027] The elastic press filter plate uses the filter plate bottom plate 1 as the base plate, and the two sides of the filter plate are provided with filter plate handles 3; There are through holes (feed holes), filter frame 2 (such as image 3 ) as the elastic moving element of the filter chamber, supported by springs, and can be combined with the filter plate to form a hollow cavity (sludge filter chamber). A filter cloth with a special shape is laid in the hollow cavity of the filter chamber, and the filter frame Vulcanized rubber 6 with a certain thickness of 0.5-10mm on the outer surface.

[0028] The electroosmotic high pressure sludge elastic press filter plate of t...

Abstract

The invention provides an electroosmosis high-voltage sludge elastic pressing filter plate which comprises a filter plate body and a filter frame.A spring enabling the filter frame and the filter plate body to stretch and contract is arranged between the filter frame and the filter plate body, a through hole is formed in the upper portion of a cross plate of the filter plate body, a U-shaped opening is formed in the upper portion of the filter frame, an opening of the U-shaped opening is communicated with a concaved cavity in the front face of the filter plate body, the center of the U-shaped opening and the center of the through hole of the filter plate body coincide, and the U-shaped opening and the through hole form a sludge feeding hole together.Sludge is conveyed into a cavity of a filter chamber through a pipeline externally connected with the feeding hole and a screw pump; by means of the feeding mode, the sludge feeding speed is high, the sludge enters the filter chamber in a free falling state, and the filter chamber can be easily filled; after the filter chamber is filled; after the filter chamber is filled, the cathode and the anode are charged, the filter chamber is compressed, and thus efficient dehydration of sludge can be achieved.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation, and in particular relates to a filter plate and a filter plate assembly. Background technique [0002] Metal plate and frame filter plates and filter frames are the main filter elements in the solid-liquid separation industry. They are mainly suitable for elastic high-voltage electroosmotic filtration of municipal sludge. The sludge filtered is generally sludge with a moisture content of 80%. , the viscosity of this sludge is relatively high. At present, the plate and frame filter devices generally used in the municipal sludge industry are middle-feed filter plates and filter frames. Moreover, the middle-feed filter plates and filter frames have the following defects during use, and the middle feed holes occupy effectively The pressure filter area affects the filtration efficiency. Sometimes the sludge has a high viscosity, and the upper corners of the sludge will not be fully fi...
