The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2: the variable chamber chamber filter plate of said chamber-type press filter mainly is made up of outer porous disc 11, bearing plate 12, interior porous disc 13, alignment pin 14, elastic component 15 and pressing plate 16; Corresponding and the equipped alignment pin 14 of shape size of said bearing plate 12 and pressing plate 16, the effect of alignment pin 14 are bearing plate 12 and pressing plate 16 can be relatively moved and can not to relatively rotate; Be respectively equipped with inner cavity and outer cavity on the lateral surface in the said bearing plate 12, said interior porous disc 13 is assemblied in the inner cavity, clamps elastic component 15 between interior porous disc 13 and the said pressing plate 16, and said outer porous disc 11 is assemblied in the outer cavity; The center of said outer porous disc 11, bearing plate 12, interior porous disc 13 and pressing plate 16 offers the circular hole 17 of perforation.The described elastic component 15 preferred springs that adopt such as traditional cylindrical shape compression spring, can certainly adopt the spring of other form.
The fit of said alignment pin 14 is as shown in Figure 1; Offer the alignment pin through hole at bearing plate 12 peripheries; Corresponding position on pressing plate 16 offers dowel hole; Alignment pin 14 is inserted and is stretched in the dowel hole that adopts on the pressing plate 16 by the alignment pin through hole on the bearing plate 12, and alignment pin 14 heads can move axially in the alignment pin through hole but can not deviate from.
As shown in Figure 1, the thickness of said interior porous disc 13 is greater than the thickness of outer porous disc 11, and thicker interior porous disc 13 has higher intensity, can sustain the pressure of elastic component 15.
As shown in Figure 1, said interior porous disc 13 all adopts polypropylene (PP) material to process with outer porous disc 11, and its corrosion resistance and intensity are all relatively good; Said bearing plate 12 all adopts steel material to process with pressing plate 16, thereby makes its structural strength obtain effective assurance.
The common filter plate 3 that the utility model will have now on the chamber-type press filter is modified into the box filter plate 3 of variable chamber; This filter plate 3 has adopted the pressing plate of being processed by steel material 16 and bearing plate 12; And between pressing plate 16 and bearing plate 12, clamped high strength elastic spare 14 and kept chamber size; Guarantee that filter plate 3 can bear the pressure reduction and the high-pressure compressing on high-pressure filteration, filter plate 3 both sides, on bearing plate 12, assembled porous disc simultaneously, guaranteed the strainability of filter plate 3.In order to cooperate the application of this kind filter plate 3, also need set up the high-pressure compressing system on the chamber-type press filter, and remaining hydraulic system, dreg removing system 8, drainage system 9 and filter residue induction system etc. still can adopt the existing parts on the chamber-type press filter.
During concrete the application; Like Fig. 1, shown in Figure 2; Box filter plate 3 horizontal parallel of the variable chamber of the utility model are arranged, and put through the handle 10 of himself to hang on the housiung separator 4, and can relatively move along arranging fore-and-aft direction; Arranging fore-and-aft direction also is the squeeze force direction of hold down gag 7, and what the hold down gag 7 of diagram chamber-type press filter adopted is hydraulic means.
Be treated to example with sludge press filtration, when charging, hydraulic system only provides an initial pressure; Slip when keeping charging (mud) does not spray material; Be equivalent to common chamber-type press filter this moment, treat that charging finishes after, the moisture content of mud is about 70%～80% in this moment filter chamber.The high-pressure compressing system starts working then, with 15 compressions of the elastic component between bearing plate 12 and the pressing plate 16, under the effect of pressing plate 16 and bearing plate 12; Mud dewaters under greater than the pressure of 1.5MPa; Mud is squeezed squeezing and further dewaters, and through squeezing, moisture percentage in sewage sludge is less than 50%; Change the dump program then over to, the mud behind the high-pressure compressing is unloaded from equipment, be transported to dried dust field, transport outward or burn, accomplish a course of work to boiler through the filter residue induction system.
