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 outerporous disc 11,bearing plate 12, interiorporous disc 13,alignment pin 14,elastic component 15 andpressing plate 16; Corresponding and the equippedalignment pin 14 of shape size of saidbearing plate 12 and pressingplate 16, the effect ofalignment pin 14 arebearing plate 12 andpressing 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 saidbearing plate 12, said interiorporous disc 13 is assemblied in the inner cavity, clampselastic component 15 between interiorporous disc 13 and the saidpressing plate 16, and said outerporous disc 11 is assemblied in the outer cavity; The center of said outerporous disc 11,bearing plate 12, interiorporous disc 13 andpressing plate 16 offers thecircular hole 17 of perforation.The describedelastic component 15 preferred springs that adopt such as traditional cylindrical shape compression spring, can certainly adopt the spring of other form.

The fit of saidalignment pin 14 is as shown in Figure 1; Offer the alignment pin through hole atbearing plate 12 peripheries; Corresponding position onpressing plate 16 offers dowel hole;Alignment pin 14 is inserted and is stretched in the dowel hole that adopts on thepressing plate 16 by the alignment pin through hole on thebearing plate 12, andalignment 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 interiorporous disc 13 is greater than the thickness of outerporous disc 11, and thicker interiorporous disc 13 has higher intensity, can sustain the pressure ofelastic component 15.

As shown in Figure 1, said interiorporous disc 13 all adopts polypropylene (PP) material to process with outerporous disc 11, and its corrosion resistance and intensity are all relatively good; Said bearingplate 12 all adopts steel material to process withpressing 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 bysteel material 16 andbearing plate 12; And betweenpressing plate 16 andbearing 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, onbearing 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 removingsystem 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 thehandle 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 betweenbearing plate 12 and thepressing plate 16, under the effect of pressingplate 16 and bearingplate 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.
