Abstract
The utility model discloses a hydraulic variable chamber filter press plate frame, which comprises a bottom plate and a frame, wherein the plate frame wholly protrudes from the frame; the plate frame has an inner recess structure; the bottom plate is arranged on one side of the frame; a feeding hole is formed on the frame; a movable push plate is arranged on the other side of the frame; a hydraulic cylinder is arranged between the bottom plate and the push plate; and the push plate is connected with the hydraulic cylinder. The hydraulic variable chamber filter press plate frame is simple in structure and easy to implement, has a cast iron structure and can bear high pressure so as not to deform and provide extremely high sealing pressure, the feeding pressure can achieve 1.6 to 2MPa, about 4MPa pressing force can be provided through internal pressing, the moisture content of the dehydrated material is about 50 percent, and the later-stage sludge treatment cost is greatly reduced.
Description
Technical field
The utility model relates to a kind of filter press frame, relates in particular to a kind of hydraulic variable chamber filter press 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, the industries such as plating, printing and dyeing, water treatment are plate and frame filter press to the capital equipment of deeply dehydrating sludge, and the filter plate integral body of general common plate and frame filter press is nonelastic hardboard, can't supercharging after compression is close to, the pressure of filter chamber almost completely provides by the pressure of sludge pump, owing to can not squeeze, and the pressure of sludge pump is limited, enough large pressure can't be provided, so after the general press filtration, moisture content is high, is about about 80%, and its filter cycle is long, inefficiency.
For the problems referred to above, filter press in the market adopts diaphragm type sheet frame and spring to become the chamber sheet frame, the diaphragm type sheet frame is after filter chamber is full of mud, by pouring pressure medium (as: air, water or oil) supercharging in filter plate, compression filter chamber volume, improve 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 fast squeezing, 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%.
The utility model content
The purpose of this utility model is for the problems referred to above, a kind of hydraulic variable chamber filter press frame is provided, less to solve traditional filter press 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 purpose of this utility model is to be achieved through the following technical solutions:
A kind of hydraulic variable chamber filter press frame, comprise base plate and frame, described sheet frame integral body is that frame protrudes, the inner recess structure, described base plate is arranged at a side of frame, has charging aperture on the described frame, and its opposite side is provided with movably push pedal, be provided with hydraulic cylinder between described base plate and the push pedal, described push pedal is connected with hydraulic cylinder.
Further, described frame and base plate are made by cast iron, steel plate or highstrenghtpiston.
Further, be provided with one or more hydraulic cylinders between described base plate and the push pedal.
Further, described hydraulic cylinder comprises that cylinder body reaches the piston that slidably is arranged in the cylinder body, and described piston one side is connected with push pedal, is provided with hydraulic oil port on the cylinder body of its opposite side.
The beneficial effects of the utility model are, described hydraulic variable chamber filter press frame is simple in structure, be easy to realize, it adopts 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 significantly reduced the disposal cost in mud later stage.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to Figure 1 and Figure 2, Fig. 1 is the cutaway view of the utility model hydraulic variable chamber filter press frame; Fig. 2 is the working state schematic representation of the utility model hydraulic variable chamber filter press frame.In the present embodiment, a kind of hydraulic variable chamber filter press frame, comprise base plate 3 and frame 1, described frame 1 and base plate 3 are made by cast iron, described sheet frame integral body is that frame 1 protrudes, the inner recess structure, described base plate 3 is arranged at a side of frame 1, be provided with charging aperture 8 on the described frame 1, and its opposite side is provided with movably push pedal 5, is provided with 4 hydraulic cylinders between described base plate 3 and the push pedal 5, and described hydraulic cylinder comprises that cylinder body 2 reaches the piston 4 that slidably is arranged in the cylinder body 2, described piston 4 one sides are connected with push pedal 5, are provided with hydraulic oil port 6 on the cylinder body 2 of its opposite side.
During work, after sheet frame holds out against by the master cylinder on the filter press, produce the 4-5MPa sealing load, then squeezed into by feed pump and be filtered material 7, allow the above quick feeding of 1.6MPa-2MPa, general feed time is get final product in 20-40 minute, and after charging finished, the interior hydraulic jack of sheet frame was started working, promote further squeezing material of push pedal 5, again reduce material water ratio, pursue lower moisture content such as need, do not need the master cylinder action can conveniently realize secondary, three chargings.After squeezing finishes, realize that by automatic pulling plate mechanism block-by-block pulls open 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 good in interactive function, and is simple, convenient.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
