Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Consult Fig. 1, Fig. 2, Fig. 3, the invention provides a kind of upper feeding electro-osmosis high pressure mud elasticity Filter pressing board and filter plate assembly；
This elasticity Filter pressing board is with filter plate base plate 1 for substrate, and the two of this filter plate are provided with handlebar of filter board 3；This filter plate has Metal Material Welding to process, filter plate top transverse slat makes triangle male-type, centre position has through hole (charging hole), filter frame 2(such as Fig. 3) as the resilient movement element of filter chamber, by spring supporting, and can with the cavity (sludge press filtration chamber) of filter plate combination formation hollow, the filter cloth of special shape is laid in the cavity of filter chamber hollow, the vulcanite 6 of the outer surface certain thickness 0.5-10mm of filter frame.
The electro-osmosis high pressure mud elasticity Filter pressing board of the present invention, including filter plate body 1 and filter frame 2, the top of filter plate body 1 is provided with through hole, the top of filter frame 2 is provided with U-shaped opening 10, the center of U-shaped opening 10 and the through hole center superposition on filter plate top, this is sewage sludge feed hole, and charging hole 9 is connected by central canal 7 and central canal nut 5 and formed, being provided around telescopic spring at charging hole 9, charging hole 9 bottom is connected with filter chamber.Upper feeding type filter cloth is set and surrounds whole filter plate and the cavity of filter frame formation, in the rubber that filter frame surface sulfide 0.5-10mm is thick, filter plate and filter frame laminating, it is ensured that the sealing of filter chamber.Filter cloth negative electrode conductive mesh 4 disposed behind and positive plate 8, two filter plate side-by-side dockings, a closing can be formed, there is the storage mud cavity of electroosmosis, filter chamber superposition one by one is in a row, the outer surface of each filter frame engages with the bottom surface of filter plate, composition surface place has filter cloth and vulcanite 6 that cavity is sealed, and forms a cavity sealed, and can add high pressure after input mud reaches 5MPa.Mud is input in filter chamber cavity by the external pipeline of charging hole 9 and screw pump, owing to being upper feeding form, sewage sludge feed rate is very fast, enter in filter chamber as free-falling state, easily it is full of filter chamber, after being full of filter chamber, negative and positive the two poles of the earth is powered up, and filter chamber is compressed, thus can realize the high-efficiency dehydration of mud.
