Detailed description of the invention:
In order to the mass dryness fraction improving mud now adopts hydraulic cylinder to extrude, squeeze force can reach 60 ㎏/cm
2, the mass dryness fraction of mud can reach more than 50%.Existing main hydraulic cylinder support is fixed on girder, and for driving variable displacement type filter press soon, the stroke of main hydraulic cylinder 3 will lengthen a lot, and the cost of this hydraulic cylinder is huge.Main hydraulic cylinder support 2 of the present invention adopts portable structure, before, before the left end of rear two girders 9 is separately fixed at thrust plate 8, rear side, before described, before the right-hand member of rear two girders is separately fixed at right support 1, rear side, guide rail 35 be fixed on described before, on the upper surface of rear girder, the guide roller 27 of main hydraulic cylinder support, flat roller 28 is placed on described guide rail, the piston rod being fixed on the main hydraulic cylinder on described support is connected with push pedal 4, the filter plate 10 of multiple variable displacement type is placed on two girders side by side, the filter plate of right-hand member is connected with described push pedal 4, the filter plate of left end contacts with described thrust plate 8, two are pulled open the side that hydraulic cylinder 7 is fixed on girder fast, its piston rod 6 is connected with main hydraulic cylinder support, plate lifting hydraulic cylinder 17 is fixed on undersetting 18, this undersetting is fixed on the upper end of main hydraulic cylinder support, and plate raise-lower hydraulic cylinder piston rod is connected with Connection Block 34, and plate 19 is fixed on the lower end of described Connection Block, described plate is door character type plate, and described girder is placed in the Jiong type of described plate, it is relative with described plate that the side of described girder is provided with limiting plate 5, (see Fig. 1,2,3,4,5).
The press dewatering principle of said structure, start main hydraulic cylinder, drive push pedal, filter plate 10 moves to thrust plate, when all transfiguration filter plates, sealing ring 32 on filter cloth 15 compresses with push pedal and thrust plate, form multiple sealed cavity, and sealing ring in each cavity on the filter cloth of both sides under pressure with the charging aperture on filter plate, when sealing gasket forms feeding-passage, main hydraulic cylinder halts, enter packing state, now just feed pump can be started, the charging aperture that material enters first the variable capacity filter plate in left side on the filter cloth sealing gasket of both sides from thrust plate charging aperture enters cavity, and each transfiguration sealed cavity injecting material to the right gradually, after each cavity fills material, under the pressure effect of feed pump, moisture in material in each sealed cavity starts to discharge through drainage channel, moisture in material is constantly extruded dehydration, material mass dryness fraction promotes gradually, when feed pressure reaches certain value, feed pump quits work.But now the mass dryness fraction of material does not still reach standard.Restarting main hydraulic cylinder, applies extruding by push pedal to each filter plate, and extrusion process adopts partial pressure section to extrude step by step, when a setup pressure value is reached, quits work.Return main hydraulic cylinder, start plate lifting hydraulic cylinder 17, plate is risen to assigned address, be separated with limiting plate, start and pull open hydraulic cylinder 7 fast, filter plate is pulled open discharging, start air bag 21, the discharging further of rapping vibration crossbeam 20, after discharging terminates, closed turnover panel, open flushing valve, start filter cloth lifting cylinder 13, filter cloth slowly rises, and rinses filter cloth comprehensively.After flushing terminates, complete whole circulation.
In order to solve in the de-material of existing extruder the sordid problem of filter cloth washing, the present invention adopts following technical proposals, by filter cloth lifting cylinder, filter cloth, filter cloth support 16, lower plumbing bar 30 and location cone 33 form, hanging bar 29 is through in the cylinder of filter cloth upper end, lower plumbing bar is through in the cylinder of filter cloth lower end, described filter cloth support 16 is placed on cleaning hose, described cleaning hose top is provided with three guide pipes, it is relative with three guide pipes 31 on cleaning hose top respectively and match that the bottom of filter cloth support is provided with three location cones, each cleaning hose is placed in filter cloth respectively, upper plate 11 on each cleaning hose is connected with push plate, it is relative with filter cloth 15 that described cleaning hose is provided with shower nozzle 23, cleaning hose 24 is connected with water main 26 by flexible pipe 25, left and right lifting cylinder is located at respectively and vibrates on bearing that crossbeam is connected, the piston rod of described lifting cylinder is connected with described lifting crossbeam, the two ends of described vibration crossbeam are placed on the air-bag support that is located on left and right support respectively, described cylinder and air bag are communicated with high-pressure air source, by PLC and solenoid control.
The operation principle of above-mentioned filter cloth washing device, when blowing terminates to rinse, opens the valve on flushing line, the top of filter cloth is rinsed, now, start filter cloth lifting cylinder, filter cloth moves up, till after the lower end of filter cloth is rinsed, filter cloth is rinsed from top to bottom, and thus filter cloth has carried out comprehensive flushing, without dead angle, filter cloth cleaning is very clean, thus ensure that the dewatering efficiency of filter cloth.
In order to improve the efficiency of blowing, in blowing process, to qi of chong channel ascending adversely and the venting repeatedly of above-mentioned air bag, thus making vibration crossbeam produce up-down vibration, driving filter cloth vibration, material is fallen from filter cloth rapidly.
About the fast opening mechanism of variable displacement type and variable displacement type filter-plate structure are prior art in said structure, be respectively the patent No. 201520090794.5 and 201520066414.4, do not repeat them here.
