The first rectangular flange 511 on the inside of the squeeze plate 51 enters the second rectangular recess 48 on the right side of the first filter press frame 40 to seal between the squeeze plate and the filter press frame. And between two adjacent filter press frames 40, the second rectangular convex edge 48' on the left side of the right one of the filter press frames 40 enters the second rectangular groove 48 on the right side of the left one of the adjacent filter press frames 40, thereby sealing the extrusion chamber 47 formed by the closing of the opposite rectangular concave pit 46 between the two adjacent filter press frames 40. As the press assembly 4 continues to be squeezed until the leftmost press frame 40 abuts the stationary plate 3, the second rectangular flange 48' on the left side of the press frame enters the first rectangular recess 311 on the inner side of the stationary plate 3 to seal between the stationary plate and the press frame. The mud from the outside is pumped into the feeding hole 312 of the fixed plate 31 and the extrusion cavity 47 formed by closing the rectangular concave pit 46 between two adjacent filter pressing frames 40 in each filter pressing frame 40 of the filter pressing assembly 4 through the mud feeding pipe 2, the outside mud is extruded in each extrusion cavity 47, the filter screen 43 at the bottom of the rectangular concave pit 46 filters the moisture in the mud, and the moisture is continuously discharged to the inner cavity 45 of the filter frame through the plurality of water filtering holes 41 at the bottom of the rectangular concave pit 46. As the extrusion plate 51 moves leftwards continuously to extrude each filter pressing frame 40, the pressure of external slurry in each extrusion cavity 47 is increased continuously, the moisture in the external slurry is filtered continuously to enter the filter frame inner cavity 45, the external slurry is discharged through the water outlet pipe 44 at the bottom of the filter frame inner cavity and flows into the water storage tank 14, and the slurry extruded with water is left in each extrusion cavity 47 and is accumulated continuously to form a mud cake. The numerical value of the pressure sensor 63 of the pressing device 6 is adjusted, so that the pressing force of the pressing steel wire rope 64 meets the requirement of treating the water content of the slurry, and the slurry discharge requirement is met. After the mud filter pressing is finished, the pressing device 6 is operated to enable the pressing winch 61 to tighten the steel wire rope 64 to be in a loose state; and operating the automatic resetting device 7, starting the resetting winch 71 to pull the resetting steel wire rope 72 to enable the extrusion plate unit 5 to move rightwards, pulling the compression filter frames 40 which are mutually tightly closed by the extrusion plate unit 5 through the connecting rope 73, and enabling mud blocks in the compression filter frames to fall off from the extrusion cavity 47 to complete mud compression filter treatment and achieve the purpose of mud-water separation.
The utility model discloses a winch wire rope straining device realizes the effect of compressing tightly to the filter-pressing subassembly through wire rope pulling stripper plate as pressure filter drive mode, through constantly the water in the extrusion messenger mud separate out through the filter-pressing frame fast, separation efficiency improves greatly, through closing device, can solve the not enough problem of tip pressure that hydraulic stem or atmospheric pressure pole lead to because of the length extension, and adopt the movable pulley can be laborsaving, choose for use miniature winch equipment, also can obtain 4 times pulling force, reach better effect that compresses tightly. The utility model discloses a set up automatic re-setting device, can make stripper plate and filter pressing subassembly automatic reply to the interval before the compression fast, the automation of the mud piece of being convenient for handle back drops and the filter frame is clean, and the structure is practical, reasonable. If the compaction winch adopts an electric driving mode, compared with the prior art, the compaction winch reduces hydraulic parts and reduces the manufacturing cost; in addition the utility model discloses a pressure filter pulp mode, with the processing mode contrast that adopts the flocculating agent, effective resources are saved, equipment use cost is low.
