Preferably; As shown in Figure 2, said piston mechanism comprises cyclic piston plate 50, and piston plate 50 is plane towards the plate face of pressing plate 10 1 sides; Piston plate 50 is provided with the protuberance of tubular towards a side of back up pad 20; Be provided with compression spring 60 between said piston plate 50 and the back up pad 20, an end of compression spring 60 is set in the outside of said tubular protuberance, and this end of compression spring 60 is resisted against the annular recess place of tubular protuberance week side; The other end of compression spring 60 is resisted against on the back up pad 20; Said tubular protuberance is offered porose on the end face of back up pad 20; The hole that the shaft of bolt 90 passes on the tubular protuberance end face is fixed together piston plate 50 and back up pad 20, is provided with pressing filtering liquid that the pressing filtering liquid that makes mud can efflux the smoothly slit of effluenting between said piston plate 50 and the back up pad 20.
Further, said piston plate 50 is provided with the groove that is looped around filter cloth week side towards the plate face of pressing plate 10 1 sides, and said annular recess place is provided with sealing-ring, to guarantee the stopping property of pressure filter in pressure-filtering process.
Elastomeric element has multiple implementation, is elastic rubber slab 70 such as said elastomeric element; Perhaps said elastomeric element is the air bag 80 that links to each other with inflator; Perhaps as shown in Figure 2, said elastomeric element is an elastic rubber slab 70, and all sides of elastic rubber slab 70 are provided with the cyclic air bag 80 that links to each other with inflator.
Make and further specifying below in conjunction with Fig. 1,2 pairs of the utility model:
The sludge carrier pipe (not shown) is connected in series these four parts through the co-axial supported hole 11 of the middle part setting of back up pad 20, retaining plate 30, elastomeric element and filter cloth 40; And sludge carrier pipe is provided with the hole of leading to mud chamber 100, and mud gets in the mud chamber 100 through the hole on the sludge carrier pipe.
When pressure filter is worked; Pressing plate 10 abuts in the platen surface of piston plate 50 under the effect of oil cylinder (not shown); The thrust direction of oil cylinder is shown in the arrow among Fig. 1; Pressing plate 10 also moves so that the mud in the mud chamber 100 is carried out press filtration to back up pad 20 promoting piston plate 50 under the effect of motor; Pressing plate 10 promotes piston plate 50 makes compression spring 60 produce compression set, and the mud in the mud chamber 100 is squeezed, and the pressing filtering liquid that press filtration goes out flows out gap 21 through filter cloth 40 from filtrate hole 31 and pressing filtering liquid and flows out; The outflow direction of pressing filtering liquid and is got rid of in the pressure filter outside through the slit of effluenting of the pressing filtering liquid between piston plate 50 and the back up pad 20 shown in the arrow among Fig. 2.
