Problems solved by technology

[0002] The plate pulling device used in the filter press can pull the filter plate in the filter press. The conventional automatic plate pulling structure has the following types: 1) Ordinary reciprocating automatic plate pulling: through a pair of manipulators on both sides of the main beam. Reciprocating pull plate, this structure is simple, the action is reliable, but relatively low efficiency
2) One-time pull plate: Equidistant chains are installed on the handles of all filter plates, and one end of the chain is fixed on the pressing plate, and a large-stroke oil cylinder or a moving oil cylinder drives the pressing plate to move, and then drags the filter plates in turn to realize automatic Pull plate, this structure has high efficiency, but it must cooperate with a large stroke, and generally the distance between filter plates is relatively small, and the length space is seriously wasted
3) Three times of pulling plates: divide all filter plates into three groups, add a middle reinforcing plate, start to pass through, press the plate as the first group of pulling plates, and pass through the middle reinforcing plate to make the second group of pulling plates, the second group of pulling plates The plate will drive the third group to move, but it does not pull the plate, and the third set of plate is pulled back through the middle reinforcing plate; the length and space of the three pulling plates are relatively saved, but the efficiency is average, and the structure is also generally responsible.
[0003] Now some patents of plate pulling devices have been disclosed. For example, on August 1, 2012, the Chinese patent with publication number CN102614693A discloses a plate pulling device for a filter press. The plate pulling device includes The running device arranged on the guide rail of the filter press, the pull plate seat set on the running device, the push plate claw and the pull plate claw are arranged on the pull plate seat, and the adjustable seat plate is arranged on the pull plate seat, The adjustable seat plate can move relative to the plate-drawing seat, the push plate claw is rotatably connected to the adjustable seat plate, and the plate-drawing claw is rotatably connected to the adjustable seat plate; during actual use In this case, the pulling device is prone to jamming
Another example is that the date of authorization announcement is April 02, 2008, and the announcement number is CN201042640Y in the Chinese patent, which discloses a filter press puller, which includes two I shafts on the puller box. The push plate and the pull plate are installed on the top, the two ends of the spring are hung on the lower part of the push plate and the pull plate, and the hook is installed on the right side of the pull plate box. The openings of the plate box are all set at the bottom, and the bearings are installed on the two II shafts above the guide rail, and the I wheel and II wheel are installed on the two III shafts below the guide rail. Since the two ends of the spring hook the pull plate and the push plate, when The pull plate and the push plate are linked by springs, and the performance is not reliable enough
Another example is that the authorized announcement date is August 25, 2010, and the announcement number is CN201558590U in the Chinese patent, which discloses a device for grouping and pulling apart filter plates of a filter press. The filter plate of the filter machine is divided into several groups, each group consists of several filter plates to form the middle filter plate, and each group is provided with a drive filter plate, the lower end of the handle installed on the middle filter plate is linear, and the lower end of the handle installed on the drive filter plate is a boss There are chain rings installed on both sides of the handle of the middle filter plate and the handle of the driving filter plate, and the chain rope or rope is connected through the chain ring, and the plate puller is connected to the boss of the drive filter plate handle, and the plate puller reciprocates to pull the filter plates apart; Since the plate puller needs reciprocating motion to pull the filter plates apart, continuous work cannot be achieved, resulting in low work efficiency
[0004] To sum up, there is currently no one-way continuous plate pulling device for filter presses with simple structure, reasonable design, convenient use, reliable performance, and high working efficiency.

Abstract

The invention relates to a press-filter unidirectional continuous plate pulling device, and aims to provide a press-filter unidirectional continuous plate pulling device with a reliable performance and high work efficiency to fill the technical blank. The device comprises a chain, two chain wheels and a plurality of mechanical arms; and is characterized in that: each mechanical arm comprises a frame, an upper limiting block, a lower limiting block, an executing member, an executing pin shaft, an executing torsion spring, a control member, a control pin shaft, and a control torsion spring; the executing member comprises an executing rod, a hooked hand, and an top pressing head; the upper limiting block, the lower limiting block, the executing pin shaft and the executing torsion spring are all fixed on the frame; the control member comprises a top torsion spring section, a position limiting section, a filter plate top pressing section, and a control section; a rotation hole is arranged on the joint part between the top torsion spring section and the position limiting section; the control pin shaft and the control torsion spring are both arrange on the frame; and the control member is movably connected to the control pin shaft through the rotation hole. The press-filter unidirectional continuous plate pulling device can unidirectionally, continuously and rapidly pull the filter plates in a press-filter and finishes the cake-unloading operation of the press-filter.
