It is a solid-liquid separation device widely used in the lithium battery industry. The filter press includes a plurality of filter plates arranged in sequence, and each filter plate is provided with a feed hole. The material will flow through the feed hole of the filter plate during filtration. After the pressure filtration is completed, there will be residual material in the feed hole.

[0036] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0037] Such as Figures 1 to 3As shown, the dredging device 10 of an embodiment includes a lateral movement driving mechanism 100, a lifting driving mechanism 200, and a brushing and dispersing mechanism 300. Among them, the lateral movement driving mechanism 100 is movably connected to the crossbeam 610 of the filter press, and the lifting driving mechanism 200 is connected to the power output end of the lateral movement driving mechanism 100, so that the lateral movement driving mechanism 100 is used to drive the lifting driving mechanism 200 to move laterally. The brushing and dispersing mechanism 300 includes a mounting platform 310, a telescopic driving member 320, a rotary driving member 330, a guiding member 340, and a brush member 350. The mounting platform 310 is fixedly connected to the power output end of the lifting driving mechanism 200, so that the lifting driving mechanism 200 is used to drive the mounting platform 310 to move in the vertical direction. The telescopic driving member 320 is mounted on the mounting platform 310, and the telescopic driving member 320 is located above the mounting platform 310. The guiding member 340 is movably connected to the mounting platform 310 in the lateral direction, and the guiding member 340 is also fixedly connected to the power output end of the telescopic driving member 320. The rotary driving member 330 is a motor, and the rotary driving member 330 is mounted on the guiding member 340. One end of the brush member 350 is fixedly connected to the power output end of the rotary driving member 330.

[0038] As Figures 1 to 3 shown, further, the lateral movement driving mechanism 100 is used to drive the brushing and dispersing mechanism 300 to move to one side of the filter plate 30 to be dredged, the lifting driving mechanism 200 is used to drive the brushing and dispersing mechanism 300 to move to the corresponding position of the feed hole of the filter plate 30 to be dredged, the telescopic driving member 320 is used to drive the brush member 350 to extend into the feed hole, and the rotary driving member 330 is used to drive the brush member 350 to rotate and dredge the feed hole.

[0039] As Figures 1 to 3As shown, in this embodiment, after the filter press finishes the pressure filtration, the pressing device 40 releases the filter plates 30, and multiple filter plates 30 are removed one by one from the pressing device 40, and the filter cake between two adjacent filter plates 30 is unloaded. After the filter cake between two adjacent filter plates 30 is discharged each time, the dredging device 10 dredges the filter plate 30 adjacent to the pressing device 40 among the corresponding two filter plates 30. When the dredging device 10 works, first, the lateral movement driving mechanism 100 drives the lifting driving mechanism 200 and the brushing and dispersing mechanism 300 to move laterally, so that the brushing and dispersing mechanism 300 is located on one side of the filter plate 30 to be dredged adjacent to the pressing device 40. Then, the lifting driving mechanism 200 drives the brushing and dispersing mechanism 300 to descend, so that the brushing and dispersing mechanism 300 is arranged corresponding to the filter plate 30 to be dredged in the lateral direction. Then, the telescopic driving member 320 drives the guiding member 340, the rotating driving member 330 and the brush member 350 to move laterally, so that the brush member 350 enters the feeding hole of the filter plate 30 to be dredged. At this time, the guiding member 340 guides the movement of the rotating driving member 330 and the brush member 350. Then, the rotating driving member 330 drives the brush member 350 to rotate, so that the brush member 350 brushes the lumps in the feeding hole, causing the lumps in the feeding hole to become loose. After brushing and loosening the lumps, the rotating driving member 330 stops, and the telescopic member drives the guiding member 340, the rotating driving member 330 and the brush member 350 to reset in the direction away from the feeding hole, so that the brush member 350 takes out the residual material in the feeding hole, so as to achieve the effect of dredging the feeding hole; after the dredging is completed, the lifting driving mechanism 200 drives the brushing and dispersing mechanism 300 to reset upward.

[0040] For the above-mentioned dredging device 10, after each unloading, the lateral movement driving mechanism 100 drives the brushing and dispersing mechanism 300 to move laterally to one side of the filter plate 30 to be dredged, and the lifting driving mechanism 200 drives the brushing and dispersing mechanism 300 to descend to the position corresponding to the feeding hole of the filter plate 30 to be dredged, so that the brush member 350 of the brushing and dispersing mechanism 300 is arranged corresponding to the feeding hole in the lateral direction. The telescopic driving member 320 drives the brush member 350 to enter the feeding hole, and the rotating driving member 330 drives the brush member 350 to rotate and brush the lumps in the feeding hole; after brushing and loosening the lumps, the rotating driving member 330 stops, and the telescopic member drives the brush member 350 to reset in the direction away from the feeding hole, so that the brush member 350 takes out the residual material in the feeding hole, so as to achieve the effect of dredging the feeding hole of the filter plate 30, realizing the mechanization of dredging the feeding hole of the filter plate 30, avoiding dredging the feeding hole manually, improving the safety performance of the filter press, and at the same time improving the dredging efficiency of the feeding hole of the filter plate 30.

[0041] As Figure 3 shown, in some embodiments, the telescopic driving member 320 is a cylinder. Of course, the telescopic driving member 320 is not limited to a cylinder. For example, in some other embodiments, the telescopic driving member 320 can also be a linear motor, a hydraulic cylinder or an existing gas linear driving member.

[0042] AsFigure 3 As shown, in some of these embodiments, the brush member 350 includes a connecting shaft 351 and a brush portion 352. One end of the connecting shaft 351 is fixedly connected to the power output end of the rotary driving member 330, and the brush portion 352 is fixedly connected to the circumferential side of the connecting shaft 351. In this embodiment, the rotary driving member 330 drives the connecting shaft 351 to rotate. Since the brush portion 352 is connected to the circumferential side of the connecting shaft 351, the brush portion 352 can directly contact the inner wall of the feed hole, enabling the brush portion 352 to scrape the accumulated material on the inner wall of the feed hole.

[0043] As Figure 3 As shown, in one of the embodiments, the dredging device 10 further includes a blowing mechanism 400. The blowing mechanism 400 includes an air pump 410 and an air pipe 420. The air pump 410 is installed on the installation platform 310. The intake end of the air pipe 420 is communicated with the outlet end of the air pump 410. The outlet end of the air pipe 420 is connected to the upper side of the guiding member 340, and the outlet end of the air pipe 420 faces the brush portion 352. In this embodiment, the air pump 410 is used to compress and output external air to the air pipe 420, and the air pipe 420 is used to spray the compressed air onto the brush member 350. After the brush member 350 leaves the feed hole, the air pump 410 is started for a period of time, so that the air outlet pipe 420 continuously blows air towards the brush portion 352 for a period of time to blow off the material in the brush portion 352, preventing the material from reducing the effect of the brush member 350 for dredging again, and enabling the brush member 350 to continuously dredge.

[0044] As Figure 3 As shown, in some of these embodiments, the blowing mechanism 400 further includes a gas filter 430. The gas filter 430 is installed on the installation platform 310. The outlet end of the air pump 410 is communicated with the intake end of the air pipe 420 through the gas filter 430. In this embodiment, the gas is filtered by the gas filter 430 to prevent impurities in the gas from contaminating the material, improving the quality of the material.

[0045] As Figure 3 As shown, in some of these embodiments, the guiding member 340 includes a fixed seat 341 and a pulley group 342. The pulley group 342 is rotatably connected to the bottom of the fixed seat 341, and the pulley group 342 is rollingly connected to the upper surface of the installation platform 310. The power output end of the telescopic driving member 320 is fixedly connected to the fixed seat 341, and the rotary driving member 330 is installed on the fixed seat 341. In this embodiment, when the telescopic driving member 320 is driven, the pulley group 342 moves along the upper surface of the installation platform 310, enabling the guiding member 340 to guide the rotary driving member 330 and the brush member 350, and improving the movement stability of the brush member 350.

[0046] As Figure 2As shown, in some of these embodiments, the dredging device 10 further includes a discharging mechanism 500. The discharging mechanism 500 is installed on the installation platform 310, and the telescopic driving member 320 and the discharging mechanism 500 are respectively located on the upper and lower sides of the installation platform 310, such that the telescopic driving member 320 and the discharging mechanism 500 are lifted and lowered synchronously, and the discharging mechanism 500 is located on the lower side of the telescopic driving member 320. In this embodiment, when the lifting driving mechanism 200 drives the brushing mechanism 300 to descend, since the discharging mechanism 500 is located on the lower side of the telescopic driving member 320, the discharging mechanism 500 shovels the filter cake on the filter plate 30 before the brush member 350 reaches the dredging position, realizing the automation of discharging, improving the efficiency of the pressure filtration operation, and at the same time exposing the feed hole, improving the convenience of dredging the feed hole.

[0047] As Figure 2 shown, in some of these embodiments, the discharging mechanism 500 includes an angle adjustment driving assembly 510 and a discharging shovel 520. The angle adjustment driving assembly 510 is connected to the lower side of the installation platform 310, and the discharging shovel 520 is fixedly connected to the power output end of the angle adjustment driving assembly 510. The angle adjustment driving assembly 510 is used to adjust the angle of the discharging shovel 520 so that the discharging shovel 520 can better shovel the filter cake off the filter plate 30.

[0048] As Figure 4 shown, in some of these embodiments, the lower end of the discharging shovel 520 is provided with a raking portion 521, and the raking portion 521 is in the shape of a rake. In this embodiment, when the discharging shovel 520 shovels and discharges, the raking portion 521 contacts the filter cake and shovels the filter cake off. At this time, the raking portion 521 can break the filter cake, avoiding the problem of filter cake bridging and improving the smoothness of discharging.

[0049] As Figure 4 shown, in some of these embodiments, the raking portion 521 includes a plurality of raking teeth 5211 arranged at intervals. In this embodiment, when the raking portion 521 shovels the filter cake, the raking teeth 5211 penetrate into the filter cake and shovel downwards, and can break the filter cake while shoveling the filter cake, improving the smoothness of material discharging.

[0050] As Figures 1 to 3As shown in the figure, the present disclosure also provides a filter press for the lithium battery industry, which includes the dredging device 10 of any of the above embodiments. The filter press further includes a frame 20, filter plates 30, and a pressing device 40. A plurality of filter plates 30 are sequentially slidably arranged inside the frame 20, and each filter plate 30 is slidably connected to the cross beam 610 of the frame 20. The pressing device 40 is arranged at one end of the frame 20, and the pressing device 40 is used to press the filter plates 30 so that the plurality of filter plates 30 are sequentially abutted. The transverse movement driving mechanism 100 is slidably connected to the cross beam 610 of the frame 20. In this embodiment, the filter plates 30 are formed with feed holes. After the plurality of filter plates 30 are sequentially abutted, the feed holes of the plurality of filter plates 30 together form a feed pipeline. Any two adjacent filter plates 30 jointly form a filter pressing assembly, so that a plurality of filter plates 30 form a plurality of filter pressing assemblies. A filter cake is formed between the two filter plates 30 of each filter pressing assembly after filter pressing.

[0051] As Figures 1 to 3 shown, in some of these embodiments, after filter pressing is completed, first, the pressing device 40 releases the filter plates 30, and then the plurality of filter plates 30 are successively moved away in the direction of the pressing device 40, so that the plurality of filter plates 30 are successively opened; the just-moved-away filter plate 30 is the filter plate 30 to be dredged. After each filter plate 30 is moved away, the filter plate 30 to be dredged is separated from the adjacent filter plate 30 to be moved away. Then, the angle adjustment driving component 510 adjusts the inclination angle of the discharge shovel 520, and then the transverse movement driving mechanism 100 drives the lifting driving mechanism 200 and the brushing and dispersing mechanism 300 to move transversely, so that the brushing and dispersing mechanism 300 is located on the side of the filter plate 30 to be dredged adjacent to the pressing device 40. Then, the lifting driving mechanism 200 drives the brushing and dispersing mechanism 300 and the discharging mechanism 500 to descend, so that the discharge shovel 520 of the discharging mechanism 500 shovels the filter cakes on the filter plates 30 on both sides of it. As the brushing and dispersing mechanism 300 and the discharging mechanism 500 continue to descend, the brushing and dispersing mechanism 300 is correspondingly arranged transversely with the filter plate 30 to be dredged. Then, the telescopic driving member 320 drives the guiding member 340, the rotary driving member 330, and the brush member 350 to move transversely, so that the brush member 350 enters the feed hole of the filter plate 30 to be dredged. At this time, the guiding member 340 guides the movement of the rotary driving member 330 and the brush member 350. Then, the rotary driving member 330 drives the brush member 350 to rotate, so that the brush member 350 brushes the lumps in the feed hole, making the lumps in the feed hole become loose. After the lumps are brushed loose, the rotary driving member 330 stops, and the telescopic member drives the guiding member 340, the rotary driving member 330, and the brush member 350 to reset in the direction away from the feed hole, so that the brush member 350 takes out the residual material in the feed hole. Then, the air pump 410 is turned on for a period of time, and the air outlet end of the air pipe 420 jets air towards the brush part 352 to blow off the materials on the brush part 352. Then, the lifting driving mechanism 200 drives the brushing and dispersing mechanism 300 and the discharging mechanism 500 to reset upward.

[0052] Compared with the prior art, the present disclosure has at least the following advantages:

[0053] After each discharging, the transverse movement driving mechanism 100 drives the brush dispersion mechanism 300 to move transversely to one side of the filter plate 30 to be dredged, and the lifting driving mechanism 200 drives the brush dispersion mechanism 300 to descend to the position corresponding to the feed hole of the filter plate 30 to be dredged, so that the brush member 350 of the brush dispersion mechanism 300 is transversely corresponding to the feed hole. The telescopic driving member 320 drives the brush member 350 to enter the feed hole, and the rotary driving member 330 drives the brush member 350 to rotate and loosen the agglomerates in the feed hole; after loosening the agglomerates, the rotary driving member 330 stops, and the telescopic member drives the brush member 350 to reset in the direction away from the feed hole, so that the brush member 350 takes out the residual materials in the feed hole, so as to achieve the effect of dredging the feed hole of the filter plate 30, realizing the mechanization of dredging the feed hole of the filter plate 30, avoiding dredging the feed hole manually, improving the safety performance of the filter press, and at the same time improving the dredging efficiency of the feed hole of the filter plate 30.

[0054] The above embodiments only represent several implementation manners of the present disclosure, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
