Abstract
The invention discloses a hydraulic variable-cavity filter-press plate frame. The plate frame comprises a bottom plate and a border frame. The integral border frame has a structure with a protruding border and a recessed inner part. The bottom plate is placed on one side of the border frame. A feeding port is arranged on the border frame. A movable push plate is arranged on the other side of the border frame. A hydraulic cylinder is arranged between the bottom plate and the push plate. The push plate is connected with the hydraulic cylinder. The hydraulic variable-cavity filter-press plate frame is advantaged in simple structure and easy realization. A cast iron structure is adopted, such that the plate frame can withstand huge pressure without deformation. An excellent sealing pressure can be provided. A feeding pressure can reach 1.6-2MPa. Internal pressing can provide a pressing force of approximately 4MPa. A water content of dehydrated material reaches approximately 50%, such that the cost of sludge post-treatment is greatly reduced.
Description
Technical field
The present invention relates to a kind of filter press sheet frame, relate in particular to a kind of hydraulic variable chamber filter press sheet frame.
Background technology
Along with country continues to increase the dynamics of environmental protection, the mud in the sewage disposal is required deep dehydration, so that subsequent treatment; At present, industries such as plating, printing and dyeing, water treatment are plate and frame filter press to the capital equipment of deeply dehydrating sludge, and filter plate integral body of general common plate and frame filter press is nonelastic hardboard, and compressing can't supercharging after being close to; The pressure of filter chamber almost completely leans on the pressure of sludge pump to provide, owing to can not squeeze, and the pressure of sludge pump is limited; Enough big pressure can't be provided, so after the general press filtration, moisture content is high; Be about about 80%, and its filter cycle is long inefficiency.
To the problems referred to above, filter press in the market adopts diaphragm type sheet frame and spring to become the chamber sheet frame, and the diaphragm type sheet frame is after filter chamber is full of mud; Through in filter plate, pouring pressure medium (as: air, water or oil) supercharging, compression filter chamber volume improves pressure; But also can only reach the squeeze force about 2MPa, charging and dwell time are longer, and energy consumption is relatively large; Moisture content is higher, is about about 60%; And spring becomes the chamber sheet frame because the sealing between its sheet frame is to depend on elastomer to produce sealing load; So it can not be applicable to high pressure charging and squeezing fast, generally can only bear the feed pressure of 0.5MPa, squeeze force is about 3MPa; Moisture percentage in sewage sludge is higher after the press filtration, is about about 60%.
Summary of the invention
The objective of the invention is to the problems referred to above; A kind of hydraulic variable chamber filter press sheet frame is provided; Less to solve traditional filter press sheet frame squeeze force, thus cause filter chamber pressure little, prolonged the high problem of moisture content behind feed time, squeezing time and the sludge press filtration.
The objective of the invention is to realize through following technical scheme:
A kind of hydraulic variable chamber filter press sheet frame comprises base plate and frame, and said sheet frame is whole to be that frame protrudes; The inner recess structure; Said base plate is arranged at a side of frame, has charging aperture on the said frame, and its opposite side is provided with movably push pedal; Be provided with hydraulic cylinder between said base plate and the push pedal, said push pedal is connected with hydraulic cylinder.
Further, said frame and base plate are processed by cast iron, steel plate or highstrenghtpiston.
Further, be provided with one or more hydraulic cylinders between said base plate and the push pedal.
Further, said hydraulic cylinder comprises that cylinder body reaches the piston that slidably is arranged in the cylinder body, and said piston one side is connected with push pedal, and the cylinder body of its opposite side is provided with hydraulic oil port.
Beneficial effect of the present invention does, said hydraulic variable chamber filter press plate mount structure is simple, be easy to realize that it adopts the cast iron structure; Can bear immense pressure and indeformable; Extremely strong sealing load can be provided, and feed pressure can reach 1.6MPa-2MPa, and inner squeezing can provide the strength of the squeezing about 4MPa; Material water ratio after the dehydration reaches about 50%, has reduced the disposal cost in mud later stage significantly.

The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment.
Please with reference to Fig. 1 and shown in Figure 2, Fig. 1 is the cutaway view of hydraulic variable of the present invention chamber filter press sheet frame; Fig. 2 is the working state schematic representation of hydraulic variable of the present invention chamber filter press sheet frame.In present embodiment, a kind of hydraulic variable chamber filter press sheet frame comprises base plate 3 and frame 1; Said frame 1 and base plate 3 are processed by cast iron, and said sheet frame integral body is that frame 1 protrudes the inner recess structure; Said base plate 3 is arranged at a side of frame 1, and said frame 1 is provided with charging aperture 8, and its opposite side is provided with movably push pedal 5; Be provided with 4 hydraulic cylinders between said base plate 3 and the push pedal 5; Said hydraulic cylinder comprises that cylinder body 2 reaches the piston 4 that slidably is arranged in the cylinder body 2, and said piston 4 one sides are connected with push pedal 5, and the cylinder body 2 of its opposite side is provided with hydraulic oil port 6.
During work, after sheet frame holds out against through the master cylinder on the filter press, produce the 4-5MPa sealing load; Squeezed into by feed pump then and be filtered material 7, allow the above quick feeding of 1.6MPa-2MPa, generally feed time is to get final product in 20-40 minute; After charging finished, the hydraulic jack in the sheet frame was started working, and promoted further squeezing material of push pedal 5; Reduce material water ratio once more, pursue lower moisture content, do not need the master cylinder action can conveniently realize secondary, three chargings like need.After squeezing finishes, realize that by automatic drawing-plate mechanism block-by-block draws back sheet frame, so that discharging.The automatic control system of this press filteration system has adopted the PLC industrial control host, has good user interface and human-computer dialogue function, and is simple, convenient.
Above embodiment has just set forth basic principle of the present invention and characteristic; The present invention is not limited by the foregoing description; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
