[0002] The existing plate filter press needs to open the filter plate one by one after filtering and then carry out deslagging, and the deslagging efficiency is low due to the large number of filter plates. In view of this problem, a high -efficient plate filter press of deslagging is designed.

[0003] After searching, in the prior art, Chinese patent document CN217511255U, published (announced) on September 30, 2022, discloses a full-automatic vertical diaphragm plate and frame filter press, which comprises a frame, filter plates and supports, the inside of the frame is provided with a plurality of filter plates, the front and rear sides of the filter plate are fixedly connected with supports, and the outer wall of the filter plate is provided with a supporting member at the top of the front and rear sides. Its characteristics are that: through the cooperation of the support plate, the rotating plate and the support plate, when the residue in the filter plate needs to be treated, the filter plate can be opened in turn, thereby increasing the working efficiency. However, the deficiency is that: since all the filter plates are expanded at the same time, the interval between adjacent filter plates is small, and the filter residue has certain adhesion, so it is not easy to separate the filter residue on the filter plate.

[0004] Similarly, Chinese patent document CN221084771U, published (announced) on June 7, 2024, discloses a quick-opening filter press, which comprises a support frame, a fixed base fixedly assembled on the outer wall of the support frame, and a pressure driving device fixedly assembled in the inner cavity of the fixed base. Its characteristics are that: a connecting chain is arranged on the outer wall of the push plate, and the outer wall of the connecting chain is connected with the outer walls of the first filter plate and the second filter plate respectively. When the pressure driving device stops applying pressure to the push plate and withdraws the push plate inward, the outer wall of the push plate will pull the filter plates outward under the action of the connecting chain. At this time, under the action of the connecting chain, the first filter plate and the second filter plate will be separated, so as to better collect and clean the filter cake in the inner cavities of the first filter plate and the second filter plate, and avoid the need to manually separate the first filter plate and the second filter plate when the push plate is withdrawn. The deficiency is that: it still does not solve the problem of how to easily separate the filter residue on the filter plate when the interval between adjacent filter plates is small. SUMMARY

[0030] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, the embodiments described below by referring to the drawings are exemplary, and are intended to explain the utility model, and can not be understood as the limitation of the utility model.

[0031] Example 1:

[0032] Please refer to Figures 1-9 ​The utility model provides a high -efficient deslagging plate filter press, including filter press body 10, the support crossbeam 11 of filter press body 10 is used to place a plurality of filter plates 20, and the both sides of adjacent filter plates 20 are connected movably through connecting structure 30, the support crossbeam 11 is equipped with jacking device 40, and the number of jacking device 40 corresponds to the number of filter plate 20, and the position of each jacking device 40 corresponds to the position of each filter plate 20 when unfolding, through setting connecting structure 30, so as to unfold each filter plate 20 simultaneously, and through the jacking device 40 installed on the support crossbeam 11, after each filter plate 20 unfolds, the filter plate 20 is lifted by jacking device 40 and is laid down again, makes the filter plate 20 vibrate, to conveniently separate the filter residue on the filter plate 20.

[0033] Figure 1 It shows the state of each filter plate of filter press when unfolding, Figure 2 It shows the state of each filter plate of filter press when folding.

[0034] Referring to Figure 3 In the embodiment, the support plate 12 is fixedly connected to the support crossbeam 11, and the jacking device 40 is installed on the support plate 12, and the jacking device 40 is located on the side of the support crossbeam 11 away from the filter plate 20.

[0035] In the embodiment, the jacking device 40 is a hydraulic oil cylinder or a gas cylinder.

[0036] In use, referring to Figure 4 , the telescopic end of the jacking device 40, i.e. the piston rod, is extended, the filter plate 20 is lifted, then the piston rod of the jacking device 40 is quickly retracted, the filter plate 20 falls down and vibrates, so as to separate the filter residue on the filter plate 20.

[0037] Embodiment 2:

[0038] The difference from embodiment 1 is that, referring to Figure 7 , the support crossbeam 11 is provided with a plurality of longitudinal through holes 13, the jacking device 40 is installed at the bottom of the support crossbeam 11, and the telescopic end of the jacking device 40 extends into the longitudinal through hole 13.

[0039] Specifically, the support crossbeam 11 is provided with a longitudinal through hole 13 at a position corresponding to each jacking device 40, the jacking device 40 has an end flange structure, and the end flange is connected and fixed to the support crossbeam 11 by bolts.

[0040] Further, referring to Figure 5 , 6 The lug seat 21 of the filter plate 20 is provided with a positioning hole 22, and the telescopic end of the jacking device 40 extends into the positioning hole 22 when the jacking device 40 lifts the filter plate 20. By providing the positioning hole 22, the telescopic end of the jacking device 40 is inserted into the positioning hole 22 when lifting, so that the filter plate 20 is stably lifted.

[0041] Example 3:

[0042] In embodiment 1 or 2, the lifting device 40 is a hydraulic cylinder with a buffer structure. When the piston rod of the hydraulic cylinder retracts into the buffer state, the piston rod is higher than the support beam 11 so that the filter plate 20 falls on the piston rod first when it falls.

[0043] Hydraulic cylinders with buffer structures are existing technology. During lifting, the piston rod extends rapidly, lifting the filter plate 20. Then, the hydraulic system controls the piston rod to retract rapidly. During retraction, the final stroke is slowed by the buffer structure, resulting in a slower retraction. As the piston rod retracts, the filter plate 20 falls onto the retracting piston rod, thus mitigating some of the impact and preventing the lugs 21 of the filter plate 20 from directly colliding with the supporting beam 11 and breaking.

[0044] Example 4:

[0045] In this embodiment, see Figure 8 , 9 The connecting structure 30 includes a connecting post 31 and a hook 32. The connecting post 31 is fixedly connected to the filter plate 20. The hook 32 is rotatably mounted on the connecting post 31. The connecting post 31 is also provided with a hook segment 33 for hooking onto the hook 32 on adjacent filter plates 20, and the hook segments 33 on adjacent filter plates 20 are staggered. For details, see [link to documentation]. Figure 1 In conjunction with CN217511255U, the hook 32 on the rightmost baffle is located on the outside, so the hook 32 on the first filter plate 20 on the right is also located on the inside, that is, the hook segment 33 on the first filter plate 20 on the right is located on the outside, and the hook 32 on the second filter plate 20 on the right is located on the outside, that is, the hook segment 33 on the second filter plate 20 is located on the outside, and the hook segment 33 is set in this way; finally, the first filter plate 20 on the leftmost side is hooked to the connecting column 31 on the pressure plate.

[0046] Specifically, the connecting post 31 is embedded and fixed to the filter plate 20. A gasket 34 and a cotter pin 35 are installed at the end of the connecting post 31 away from the filter plate 20 to limit the hook 32.

[0047] When filter plate 20 is closed, see Figure 2 Hook 32 can be flipped upwards; when filter plate 20 is unfolded, see Figure 1 The hook 32 on the right filter plate 20 is hooked onto the hook section 33 of the connecting column 31 on the left filter plate 20. This structure makes it easy to lift the filter plate 20 directly when the filter screen on the filter plate 20 needs to be replaced.

[0048] The working principle or operation process of this utility model is as follows:

[0049] Referring to Figure 1 When the filter plates 20 are folded, the hooks 32 can be flipped upwards, and the hooks 32 do not affect the folding of the filter plates 20. When the filter plates 20 are unfolded, referring to Figure 1 , the hooks 32 on the right filter plates 20 are hooked on the hook sections 33 of the connecting columns 31 on the left filter plates 20. Then, the lug seats 21 on both sides of the filter plates 20 correspond to the jacking devices 40 on both sides, respectively, and each jacking device 40 repeatedly operates multiple times in sequence or at intervals, so as to vibrate each filter plate 20, facilitating the filter residues on the filter plates 20 to be separated.
