Detailed description of the invention:
In conjunction with following embodiment, the utility model is described in detail, in order to the material cavity that the side overcoming the central layer in prior art filter plate is fluted formed, cause filter cloth deflection in extrusion process fragile greatly, the defect that life-span is short, lower ring plate is changed into the annular slab that center is hole, the ring surface of the left-hand face of central layer and lower ring plate 14 left end is made to form the cavity holding material, and it is identical with the material cavity that upper press ring plate 12 ring surface is formed with central layer right lateral surface, when identical material cavity volume, left, the degree of depth of right material cavity only has the half of an original material cavity degree of depth, the deflection of filter cloth reduces, thus its life-span is longer.In order to improve the dewatering efficiency of filter plate further, further cavity structure is arranged in the centre of central layer 11, the lower end of this cavity is communicated with air, the cylinder 19 of evagination that the left and right sidewall of this cavity distributes, and the sidewall between cylinder is opened axial hole 20 and is communicated with described cavity 18.Due to the pipelined channel that formed between cylinder and and cavity connects, thus drainage efficiency improves greatly.To the structure of spring 13 in existing variable displacement type filter plate and stop collar 16, screw 17(see Fig. 4) not change, the central layer after improvement is connected with lower skateboard screw 15.
The utility model is in order to overcome prior art in discharging and flushing process, and filter plate needs to pull open one by one, close inefficient defect.The utility model adopts following structure, connects between adjacent filter plate 5 with connecting plate 4.Described connecting plate 4 is triangular plate, is provided with the hole be hinged with filter plate bearing pin in this leg-of-mutton one end, and the hole being provided with a L shape at the other end of this connecting plate coordinates with the pin slide on adjacent filter plate.When discharging or when rinsing filter cloth, pulled open by each filter plate by main hydraulic cylinder and the arm-tie hydraulic cylinder 3 of opening soon that is arranged in girder both sides, carry out discharging or flushing, thus efficiency improves greatly simultaneously.
Utility model works principle, two girder 1 one end are fixed on thrust plate 2 both sides, and the other end is fixed on after-poppet both sides, and guide rail is fixed in the upper plane of girder 1, and main hydraulic cylinder support 6 is supported on the guide rail of girder.Push plate is connected with main hydraulic cylinder, and push plate and each group between filter plate 5 are interconnected integral by connecting plate 4, and be supported on the guide rail of girder, the both sides of each filter plate 5 are hung with filter cloth 9.The hanging of each filter cloth is on cleaning hose, and each cleaning hose is connected by connecting plate, and last root cleaning hose is connected with push plate.Thrust plate device is provided with charging aperture, and the hole on the Gask-O-Seal on the charging aperture of this charging aperture and filter plate and filter cloth is identical and be arranged on same center line.
Above-mentioned push plate, thrust plate and each filter plate and filter cloth form whole press filteration system.In said structure except filter plate has done improvement described above, all the other all structures are prior art.
During operation, start main hydraulic cylinder to move forward, drive push plate device that each filter plate 5 and filter cloth 9 are pressed to thrust plate, sealing ring on each filter plate and push plate and thrust plate are compressed, forms multiple annular seal space, the sealing ring on the filter cloth of each annular seal space both sides seals with the charging aperture on filter plate under pressure, form feeding-passage, now, main hydraulic cylinder halts, and enters packing state.Start feed pump, material passes through after the charging aperture inflow annular seal space first filter plate on the filter cloth sealing ring of both sides from thrust plate charging aperture, enter in the annular seal space that each filter plate and filter cloth form one by one backward, after the material that each annular seal space is to be extruded fills, under the pressure effect of feed pump, moisture in each annular seal space in material is discharged to the drainage channel on filter plate by filter cloth, along with continuous pressurizing and dehydrating, material concentration constantly increases, charging reduces gradually, when feed pressure reaches certain value, feed pump quits work, close material inlet valve, open two blowback valves, utilize high-pressure blast by the material blowout in feed pipe and filter plate charging hole, for charging is prepared next time, close two blowback valves, close main valve.Start main hydraulic cylinder and further press dewatering is carried out to material, under the pressure that main hydraulic cylinder is powerful, variable volume in each filter plate reduces gradually, the further press dewatering of material, when a predetermined pressure has been reached, main hydraulic cylinder returns to charging packing state position, now each filter plate returns to initial sealing state under the effect of himself spring 13, and at this moment, filter plate cavity is greater than the volume of compressed material, open material inlet valve and main valve, enter next round charging, expressing process.After squeezing terminates, main hydraulic cylinder is return, start turnover panel hydraulic cylinder 8, turnover panel 7 is raised up to plumbness, start plate hydraulic cylinder, plate is promoted to precalculated position, start and open arm-tie hydraulic cylinder 3 soon, open arm-tie hydraulic cylinder soon to advance, main hydraulic cylinder support is driven slowly to move backward along main beam guide track, main hydraulic cylinder support drives push plate to move backward, push plate drives filter plate and flusher to move backward by connecting plate, when opening after each filter plate and flusher pull open precalculated position by arm-tie hydraulic cylinder soon, open arm-tie hydraulic cylinder soon to halt, open air bag intake valve, utilize the thrust of air bag, flusher is mentioned, flusher is utilized to drive filter cloth to promote, the material cake squeezed is unloaded, close air bag intake valve again, flusher and filter cloth are resetted, so repeatedly several times, until material cake is unloaded completely.Open turnover panel hydraulic cylinder, turnover panel is fallen after rise and puts to connecing liquid level, open flushing valve, utilize flusher to carry out high pressure washing to filter cloth, rinse after terminating, closing flushing valve door.Start and open arm-tie hydraulic cylinder soon, make hydraulic cylinder rollback, main hydraulic cylinder support is driven slowly to move forward along main beam guide track, main hydraulic cylinder support drives push plate to move forward, and push plate drives filter plate and flusher to move forward by connecting plate, when opening after each filter plate and flusher be closed into precalculated position by arm-tie hydraulic cylinder soon, open arm-tie hydraulic cylinder soon to stop retreating, start plate hydraulic cylinder, plate is drop to precalculated position, completes single pressing process.
