Description

Technical Field

[0001] This utility model relates to the field of diaphragm processing technology, and in particular to a diaphragm material volume reduction device. Background Technology

[0002] In the existing battery recycling industry, the separator material is often in a loose state after being crushed and sorted. The separator material occupies a large volume, resulting in low storage space utilization and high transportation costs. Utility Model Content

[0003] The purpose of this utility model is to provide a diaphragm material volume reduction device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a diaphragm material volume reduction device, comprising: a first housing with a volume reduction cavity on one side, the cross-sectional area of ​​the volume reduction cavity gradually decreasing from the opening to the bottom wall; a second housing with a horizontally arranged compression channel having one end connected to the opening of the volume reduction cavity, a discharge hopper being provided at the top of the second housing, the discharge hopper being connected to the compression channel; and a thrust member with a pressure plate installed at the output end, the cross-sectional shape of the pressure plate being the same as the shape of the opening of the volume reduction cavity, the thrust member being used to drive the pressure plate to slide within the compression channel.

[0005] This technical solution has at least the following beneficial effects: The diaphragm material is fed from the hopper into the compression channel, and then the thrust component drives the pressure plate to slide within the compression channel. The pressure plate pushes the material into the volume-reducing chamber for compression, causing the diaphragm material to form a block-shaped compressed structure with a gradually decreasing cross-sectional area from one end to the other. This block-shaped compressed structure is more compact. While reducing the space occupied by the diaphragm material, it also reduces the stress concentration at the corners of the block-shaped compressed structure, preventing localized deformation or even breakage during stacking or transportation.

[0006] As a further improvement to the above technical solution, the cross-section of the volume-reducing cavity is square, and the inclination angles of the sidewalls of the volume-reducing cavity are all the same. The trapezoidal bevel design can reduce stress concentration at the corners, making the stress more evenly distributed on the diaphragm surface. The gradual angle of the bevel can also optimize the pressure transmission path, reduce the risk of warping or tearing at the edges due to uneven stress, thereby enhancing structural stability, and allowing the compressed diaphragm to remain intact for a long time.

[0007] As a further improvement to the above technical solution, it also includes a rotating shaft and a first driving component for driving the rotating shaft to rotate. The rotating shaft rotates horizontally within the discharge hopper, and multiple blades are mounted on the rotating shaft. By rotating the blades to initially disperse the diaphragm material, material bridging within the discharge hopper can be prevented.

[0008] As a further improvement to the above technical solution, the bottom of the first housing has a drop opening that connects to the volume reduction cavity. A lower sealing plate is slidably disposed on the bottom of the first housing to cover the drop opening. The first housing is equipped with a second driving member for driving the lower sealing plate to slide. By driving the lower sealing plate to slide through the second driving member, the drop opening can be opened to allow the compressed block-shaped structure to fall out.

[0009] As a further improvement to the above technical solution, a material box is placed next to the first box, and a conveyor belt mechanism is arranged at the bottom of the first box to lift and transport the compressed material falling from the drop outlet to the material box. After the block-shaped compressed structure falls from the drop outlet, it falls onto the conveyor belt mechanism and is transported to the material box by the conveyor belt mechanism, thereby allowing the compressed block-shaped compressed structure to be collected and stacked.

[0010] As a further improvement to the above technical solution, a push plate is vertically slidably disposed on the top of the volume reduction cavity in the first housing, and a third driving member is installed in the first housing to drive the push plate to slide. By driving the push plate downward by the third driving member, the compressed block structure can be pushed down, preventing the block structure from sticking to the wall of the volume reduction cavity and being unable to fall.

[0011] As a further improvement to the above technical solution, a guide rod is installed on the top of the push plate, and the guide rod passes through the top of the first housing. Under the guidance of the guide rod, the stability of the push plate sliding can be improved.

[0012] As a further improvement to the above technical solution, a partition is slidably arranged between the second housing and the discharge hopper, and a fourth driving component is installed in the second housing to drive the partition to slide. By driving the partition to slide through the fourth driving component, the connection between the compression channel and the discharge hopper inside the second housing can be cut off, thereby preventing material from entering the push plate on the side away from the first housing.

[0013] As a further improvement to the above technical solution, a pressure sensor is installed on the bottom wall of the volume reduction chamber. The pressure sensor can detect the pressure of the material inside the volume reduction chamber, thereby determining whether the material inside the volume reduction chamber has reached the preset compression mass.

[0014] As a further improvement to the above technical solution, the bottom of the second box body, away from the first box body, has multiple mesh openings. A storage drawer is slidably installed on the bottom of the second box body, below the multiple mesh openings. When some material debris falls onto the side of the push plate away from the first box body, the material debris can be pushed to the mesh openings during the push plate's return stroke, and then fall from the mesh openings into the storage drawer for storage.

[0025] Reference Figure 1-4 The diaphragm material volume reduction device includes a frame 101, a first housing 100, a second housing 200, and a thrust member 400, all of which are mounted on the frame 101. A volume reduction cavity 110 is provided on one side of the first housing 100. The volume reduction cavity 110 has a square cross-section, and its cross-sectional area gradually decreases from the opening to the bottom wall. The inclination angles of the four sides of the volume reduction cavity 110 are all the same, thus making the volume reduction cavity 110 space truncated pyramidal, meaning that the cross-section or horizontal section of the volume reduction cavity 110 in another direction is an equilateral trapezoid. For example, the opening size of the volume reduction cavity 110 may be 250mm*250mm, the bottom wall size may be 150mm*150mm, and the length of the volume reduction cavity 110 may be 255mm.

[0026] The second housing 200 is attached to the side of the first housing 100 that has the volume-reducing cavity 110. The second housing 200 is provided with a compression channel 210 with a uniform cross-section. One end of the compression channel 210 passes through one side of the second housing 200 and communicates with the opening of the volume-reducing cavity 110. A through hole is provided at the top of the second housing 200, connecting it to the outside and the compression channel 210. A discharge hopper 300 is also installed at the top of the second housing 200. The bottom of the discharge hopper 300 communicates with the through hole, thus connecting the discharge hopper 300 to the compression channel 210. Material can enter the compression channel 210 through the discharge hopper 300. The two sides of the discharge hopper 300 are inclined, making the whole structure funnel-shaped to facilitate material loading.

[0027] A pressure plate 410 is slidably disposed within the compression channel 210 along its length. The cross-sectional shape of the compression channel 210, the cross-sectional shape of the pressure plate 410, and the opening shape of the volume reduction cavity 110 are all identical. A thrust member 400 is located on the side of the second housing 200 away from the first housing 100. The thrust member 400 is a power-driven component that can provide significant thrust, such as a cylinder, hydraulic cylinder, or electric push rod. The output end of the thrust member 400 is connected to the side of the pressure plate 410 away from the volume reduction cavity 110. By driving the thrust member 400, the pressure plate 410 can be slid within the compression channel 210, thereby pushing the material within the compression channel 210 into the volume reduction cavity 110, where it is compressed to form a high-density block-shaped compressed structure. This reduces the space occupied by the material, thereby improving storage space utilization and reducing transportation costs.

[0028] In other embodiments, the cross-section or horizontal section of the volume-reducing cavity 110 in another direction can also be configured as a right-angled trapezoid. In other embodiments, the cross-section of the internal space of the volume-reducing cavity 110 can also be configured as a circle, hexagon, etc.

[0029] A rotating shaft 310 is rotatably mounted inside the discharge hopper 300. Both ends of the rotating shaft 310 are rotatably mounted on two non-inclined sides of the discharge hopper 300 via bearings. A first drive unit 320, which is a drive motor, is mounted on the top of the second housing 200. The output end of the first drive unit 320 is connected to one end of the rotating shaft 310 via a coupling. Multiple blades 330 are arranged around the outer periphery of the rotating shaft 310. The blades 330 extend outwards in a direction perpendicular to the axis of the rotating shaft 310. When material is placed into the discharge hopper 300, the first drive unit 320 drives the rotating shaft 310 to rotate, which in turn drives the blades 330 to break up the material, preventing bridging within the discharge hopper 300 and ensuring it falls into the compression channel 210. In other embodiments, a vibration mechanism can be installed inside the discharge hopper 300 to vibrate the material placed inside the discharge hopper 300, which can also prevent the material from bridging inside the discharge hopper 300 and failing to fall into the compression channel 210.

[0030] A partition 800 is slidably disposed between the top of the second housing 200 and the bottom of the discharge hopper 300. A fourth driving component 810 is installed in the second housing 200. The fourth driving component 810 is a power component that can provide linear motion, such as a cylinder, hydraulic cylinder, or electric push rod. The output end of the fourth driving component 810 is connected to one side of the partition 800. By driving the partition 800 to slide, the partition 800 can extend out between the top of the second housing 200 and the bottom of the discharge hopper 300, allowing material to smoothly enter the compression channel 210 from the discharge hopper 300. When the driving plate 410 pushes the material in the compression channel 210, the fourth driving component 810 can drive the partition 800 to be positioned between the top of the second housing 200 and the bottom of the discharge hopper 300, thus allowing material to enter the compression channel 210 and preventing material from entering the side of the pressure plate 410 away from the volume reduction chamber 110.

[0031] Multiple mesh openings 220 are provided at the bottom of the second housing 200 at the end away from the first housing 100. One end of each mesh opening 220 connects to the compression channel 210, and the other end connects to the outside of the second housing 200. A storage drawer 230 is also slidably installed at the bottom of the second housing 200 at the end away from the first housing 100. The opening of the storage drawer 230 faces the mesh openings 220, so as to accommodate the debris that falls out of the mesh openings 220. When the pressure plate 410 moves away from the reduction chamber 110, i.e., during its return stroke, the debris in the compression channel 210 is pushed by the pressure plate 410 to the end away from the first housing 100, i.e., the location of the mesh openings 220. This allows the debris to fall from the mesh openings 220 into the storage drawer 230, preventing the continuous accumulation of debris from affecting the sliding movement of the pressure plate 410 within the compression channel 210.

[0032] The bottom of the first housing 100 has a drop opening, the top of which connects to the reduction cavity 110, and the bottom of which connects to the outside of the first housing 100. A lower sealing plate 500 is slidably mounted on the bottom of the first housing 100, enclosing the drop opening to prevent material from falling out of the reduction cavity 110. A second driving component 510 is mounted on one side of the first housing 100 via a bracket. The second driving component 510 is a power component that can provide linear motion, such as a cylinder, hydraulic cylinder, or electric push rod. The output end of the second driving component 510 is connected to the lower sealing plate 500, so that the lower sealing plate 500 can slide, so that the lower sealing plate 500 no longer covers the drop opening, and the compressed material in the reduction cavity 110 can fall out of the drop opening for collection.

[0033] Dust covers are provided on both the fourth drive component 810 and the second drive component 510.

[0034] The first housing 100 is provided with a push plate 700, which is located at the top of the volume reduction cavity 110 and can slide vertically relative to the first housing 100. It can be understood that the bottom of the push plate 700, the top of the lower sealing plate 500, and the three side walls inside the first housing 100 together form the volume reduction cavity 110.

[0035] A third drive unit 710 is mounted on the top of the first housing 100. The third drive unit 710 is a power component that can provide linear motion, such as a cylinder, hydraulic cylinder, or electric push rod. The output end of the third drive unit 710 faces downward and passes through the top of the first housing 100 to connect with the push plate 700. The third drive unit 710 can drive the push plate 700 to slide up and down, so as to push the compressed material in the volume reduction chamber 110 out of the drop port.

[0036] Guide rods 720 are installed on both sides of the top of the push plate 700 and at the output end of the third drive unit 710. The guide rods 720 are vertically arranged and pass through the top of the first housing 100, and can slide vertically relative to the top of the first housing 100. Under the guidance of the guide rods 720, the up-and-down sliding process of the push plate 700 can be made more stable and reliable.

[0037] Furthermore, a pressure sensor 900 is installed on the bottom wall of the volume reduction chamber 110. When the material in the volume reduction chamber 110 is compressed to a certain mass, the pressure plate 410 will continue to push the material, transmitting pressure to the pressure sensor 900. Therefore, by monitoring the value of the pressure sensor 900, it can be preliminarily determined whether the compressed material in the volume reduction chamber 110 has reached the preset compression mass, so that the lower sealing plate 500 can be opened in time to drop out and collect the compressed material.

[0038] A material box 600 is placed next to the first housing 100, and a conveyor belt mechanism 610 connects the frame 101 and the material box 600. One end of the conveyor belt mechanism 610 is located at the bottom of the drop outlet, and the other end is located at the top opening of the material box 600. Through the conveying action of the conveyor belt mechanism 610, the compressed material falling from the drop outlet can be transported to the material box 600 for storage. Among them, the section of the conveyor belt mechanism 610 near the drop outlet is a horizontal conveying section, and the section of the conveyor belt mechanism 610 near the material box 600 is an inclined climbing section, thereby raising the compressed material to a certain height before dropping it into the material box 600.

[0039] The operation steps in this embodiment are as follows:

[0040] ① The weight of a single battery separator package is 120kg, and the material is added manually.

[0041] ② It takes about 30 seconds to manually fill the hopper 300 with diaphragm paper. After filling, the weight of the diaphragm paper in the hopper 300 is about 1.5-2kg. The cycle of the material blocking plate 800 is 30 seconds. After the plate 800 is in the open position, it is held for 3 seconds. Under the action of the blade 330, the bridging of the diaphragm paper can be avoided. Within 3 seconds, all the material in the hopper 300 can enter the compression channel 210.

[0042] ③ After the material enters the compression channel 210, the thrust member 400 pushes the diaphragm material into the volume reduction cavity 110 of the tetrahedral mold through the servo-controlled pressure plate 410 for extrusion. When the thrust member 400 reaches the preset maximum stroke, if the pressure sensor 900 does not reach the set pressure (e.g., 1700 kg), the above step ② is repeated until the set pressure of 1700 kg is finally reached. Then, the thrust member 400 servo-controlled pressure plate 410 moves back 12 mm to perform pre-pressure relief and prepare for unloading.

[0043] ④ After the lower sealing plate 500 is in place, the third drive component 710 servo controls the push plate 700 to unload the material. The compressed truncated pyramid diaphragm material falls onto the conveyor belt mechanism 610 and is then transported to the material box 600. It is then packaged in ton bags. The weight of the compressed material exceeds 500 kg / ton bag.

[0044] The advantages of this embodiment are as follows:

[0045] (1) The structure of this equipment is relatively simple, and the main actions are all horizontal pushing. It has a low failure rate and high reliability during use.

[0046] (2) The compression mold is designed in a trapezoidal shape. Traditional rectangular molds tend to produce rectangular diaphragms with stress concentration points at the four right angles, especially during compression, where the shear and bending stresses at the edges are relatively high. When the material is loose or thin, this stress concentration can lead to local deformation or even cracking, resulting in a loose overall structure. The trapezoidal diaphragm produced by this equipment has a significant advantage in stress dispersion. The trapezoidal design reduces stress concentration at the right angles, allowing the stress to be distributed more evenly on the diaphragm surface. The gradual angle of the bevel also optimizes the pressure transmission path, reducing the risk of warping or tearing at the edges due to uneven stress, thereby enhancing structural stability. The compressed diaphragm can remain intact for a long time.

[0047] (3) The equipment drives the partition plate 800 and the rotating shaft 310 to move, which can realize the material entering the compression channel 210 evenly. It can be integrated into the existing production line to directly press the produced diaphragm into blocks, or the equipment can be used manually to press the produced diaphragm into blocks separately. The equipment has a wide range of applications.

[0048] (4) This equipment has a high compression ratio, and the density of the compressed material can reach 1500 kg / m³. 3The compression ratio can reach 10:1.

[0049] (5) After the diaphragm is reduced in volume by this equipment, it can greatly alleviate the pressure of diaphragm material storage and transportation, and can greatly improve the feeding speed in the subsequent pyrolysis process.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
