The box body 200 is located on one side of the water tank 100. The box body 200 includes a first chamber 210. The first chamber 210 is used to place waste batteries. The first chamber 210 has a connecting hole 220 connected to the outside of the box body 200. The box body 200 is provided with a fixing member 230 for opening or closing the connecting hole 220. A pushing member 240 is provided in the first chamber 210. The pushing member 240 is used to The first chamber 210 is used to push the used battery to move, so that the used battery can be moved out of the box body 200 from the connecting hole 220 and fall into the water tank 100; the piercing head 300 is movably arranged in the first chamber 210; the separation structure 400 is arranged in the first chamber 210, and the separation structure 400 is used to prevent the used battery after puncture from moving with the piercing head 300, so that the piercing head 300 is separated from the used battery; the vacuum device is connected to the first chamber 210, and is used to vacuum the first chamber 210; the second chamber 500 is connected to the first chamber 210, and the second chamber 500 is used to receive the liquid in the first chamber 210.

[0027] The utility model uses a vacuum pumping device to evacuate the first chamber 210, so that the air content and temperature of the first chamber 210 are low, which avoids the chemical reaction between the electrolyte and the air flowing out after the waste battery is punctured and the temperature of the waste battery is too high, and makes only a small part of the electrolyte in the waste battery flow out under the action of negative pressure, further avoiding the chemical reaction between the electrolyte and the air, thereby reducing the safety hazards of the waste battery during discharge; by providing a separation structure 400, the punctured waste battery is separated from the piercing head 300, which is convenient for the pusher 240 to push the waste battery into the water tank 100 without manual operation; by providing a water tank 100 on one side of the box body 200, the waste batteries after puncture can enter the water tank 100 for further collection of electrolyte and Discharging, that is, the waste battery is discharged twice and the electrolyte is collected twice before subsequent work is carried out, thereby reducing the risk of explosion of the discharged battery in the subsequent work process. In addition, when the waste battery is temporarily stored in the water tank 100, the electrolyte volatilization can be avoided, so there is no need to conduct a secondary inspection of the discharged battery, which can ensure safe and efficient discharge; the electrolyte in the first chamber 210 is recovered through the second chamber 500 to avoid contact between the electrolyte and the human body, thereby improving the safety of the equipment; based on the above scheme, the utility model can crush and discharge soft-pack batteries, aluminum shell batteries or steel shell batteries in large quantities and quickly, and can avoid the fire risk caused by heat accumulation caused by over-discharge or short circuit during the discharge process, and can reduce the risk of electrolyte discharge.

[0028] Specifically, the piercing head 300 can move up and down, left and right, or forward and backward. Figure 2 As shown, the utility model takes the example that the piercing head 300 is movably arranged in the first chamber 210 up and down, and a driving device is installed on the top of the box body 200. The driving device and the piercing head 300 are insulated. The driving device can be a cylinder or an oil cylinder. The extension rod of the oil cylinder passes through the box body 200 and extends into the first chamber 210 to connect with the piercing head 300. The extension rod is dynamically sealed with the box body 200 to ensure that the first chamber 210 is not connected to the outside. When working, the oil cylinder is started, and the oil cylinder drives the piercing head 300 to move up and down; the pushing member 240 can be a cylinder or an oil cylinder; the separation structure 400 can be a cylinder, and the waste battery is clamped by the cylinder so that the waste battery does not move with the piercing head 300, thereby realizing the separation of the waste battery and the piercing head 300.

[0029] Furthermore, a spray device (not shown in the figure) for cooling the used batteries is installed in the first chamber 210, which reduces the volatilization amount and temperature of the electrolyte during the puncture process, thereby ensuring that the safety hazards of the used batteries during discharge are reduced; specifically, Figure 2 As shown, the spray device includes a spray pipe 290 .

[0030] Furthermore, if Figure 1 ,2 As shown, the separation structure 400 includes a fixing plate 410, which is disposed in the first chamber 210. The fixing plate 410 is used to prevent the waste battery from following the thorn head 300. The waste battery and the thorn head 300 are automatically separated by the fixing plate 410, so that the structure of the battery fast discharge device is simple, such as Figure 2 As shown, during operation, the used battery is located at the bottom of the first chamber 210, and at least a portion of the used battery is located below the fixed plate 410. The piercing head 300 moves downward to pierce and discharge the used battery. After the discharge is completed, the piercing head 300 moves upward. After the used battery moves upward for a distance following the piercing head 300, the used battery is blocked by the fixed plate 410, and the used battery automatically separates from the piercing head 300. After the used battery is separated from the piercing head 300, the used battery is not blocked by the piercing head 300, and the pushing member 240 can push the used battery to move. The used battery moves under the push of the pushing member 240 and falls into the water tank 100 through the connecting hole 220.

[0031] Furthermore, if Figure 1 As shown, the side of the fixing plate 410 is connected to the side wall of the first chamber 210, and the fixing plate 410 is provided with a first through hole 411 for the spike 300 to pass through, so as to accommodate waste batteries of different sizes.

[0032] Specifically, the fixing plate 410 may be a grid plate.

[0033] Furthermore, if Figure 3 As shown, the second chamber 500 is located in the box body 200, and the second chamber 500 is located below the first chamber 210. The bottom of the first chamber 210 has a second through hole 211. The second chamber 500 is connected to the first chamber 210 through the second through hole 211, so that the spray water and the electrolyte automatically fall into the second chamber 500 under the action of their own weight, without the need for mechanical devices, so that the structure of the battery fast discharge device is simple and the manufacturing cost is low.

[0034] Specifically, the bottom of the first chamber 210 may be a grid plate.

[0035] Furthermore, if Figure 3 As shown, the box body 200 includes a frame body 250 and a door body 260. The frame body 250 is provided with a first chamber 210 and a second chamber 500. One side of the frame body 250 has an opening 251 connected to the first chamber 210. The door body 260 is detachably mounted on the frame body 250. The door body 260 is used to open or close the opening 251. The first chamber 210 is provided with the door body 260 to facilitate moving waste batteries into the first chamber 210 and repairing and cleaning the internal structure of the first chamber 210. Specifically, the door body 260 has a sealing strip on one side close to the frame body 250, and the door body 260 and the frame body 250 press the sealing strip against each other to achieve sealing.

[0036] Furthermore, if Figure 3 As shown, one side of the frame 250 has a support platform 270, and the height of the support platform 270 is greater than the height of a part of the bottom surface of the first chamber 210. The other part of the bottom surface of the first chamber 210 is an inclined surface 212, and the support platform 270 is connected to a part of the bottom surface of the first chamber 210 through the inclined surface 212; the bottom surface of the first chamber 210 is provided with an inclined surface 212, so that when the waste batteries on the support platform 270 are moved onto the inclined surface 212, the waste batteries automatically slide into the inside of the first chamber 210 under the action of the inclined surface 212.

[0037] Furthermore, if Figure 1 As shown, a guide block 280 for guiding the sliding of the used battery is installed on the inclined surface 212, so as to ensure that the used battery moves to the bottom of the piercing head 300 and ensure the puncture discharge effect; there can be several guide blocks 280, specifically, the inclined surface 212 has two guide blocks 280 arranged at intervals along the left and right directions of the box body 200. When working, the used battery moves between the two guide blocks 280, and the two guide blocks 280 jointly guide the movement of the used battery to ensure that the used battery moves to the bottom of the piercing head 300.

[0038] Furthermore, if Figure 1 As shown, the upper end of the support platform 270 has a slide groove 271, and the bottom of the door body 260 is slidably connected to the slide groove 271 to ensure that the left and right ends of the door body 260 are always relatively aligned when the door body 260 moves, thereby ensuring the sealing effect between the door body 260 and the frame body 250; specifically, the door body 260 is connected to an oil cylinder or an air cylinder.

[0039] Furthermore, if Figure 2 As shown, the upper end of the fixing member 230 is rotatably mounted on the outer side of the box body 200, so as to facilitate the opening and closing of the connecting hole 220; when the connecting hole 220 needs to be sealed, the fixing member 230 can keep rotating downward under the action of its own weight, thereby keeping in contact with the box body 200, and further in contact with the box body 200 under the action of vacuum, so as to achieve the sealing of the connecting hole 220; when the connecting hole 220 needs to be opened, the first chamber 210 is air-intaken, the first chamber 210 is balanced with the atmospheric pressure, the atmospheric pressure outside the fixing member 230 disappears, and the pushing member 240 pushes the used battery to move and pushes the fixing member 230 away, so as to achieve the opening of the connecting hole 220; specifically, the fixing member 230 is connected with a sealing strip.

[0040] Furthermore, the box body 200 has a vacuum port 201 , which is in communication with the first chamber 210 , and the vacuum device includes a vacuum pump connected to the vacuum port 201 .

[0041] The workflow of this utility model:

[0042] 1. If Figure 3 As shown, the door 260 is opened, and the used batteries are manually placed between the frame 250 and the door 260 and on the support platform 270. After the photoelectric switch recognizes the used batteries, the system meets the start-up conditions;

[0043] 2. If Figure 2 , 3 As shown, the oil cylinder drives the door body 260 to move toward the frame body 250, and at the same time, the door body 260 pushes the waste battery to move along the support platform 270. When the door body 260 moves to the inclined surface 212, the waste battery falls to the bottom of the thorn head 300 and the bottom of the fixing plate 410 under the action of the inclined surface 212. When the door body 260 abuts against the frame body 250, the sealing is achieved through the sealing strip. The fixing member 230 presses the sealing strip tightly due to its own weight to seal the connecting hole 220.

[0044] 3. If Figure 2 As shown, the vacuum pump performs vacuum processing on the first chamber 210 through the vacuum port 201, and when the vacuum degree is lower than 1000 Pa, the next step condition is met;

[0045] 4. If Figure 2 As shown, after the vacuum degree meets the requirement, the oil cylinder drives the piercing head 300 to move downward, and the piercing head 300 sequentially passes through the first through hole 411, the waste battery, and the second through hole 211. After the waste battery is punctured, a short circuit is formed to release energy, thereby achieving rapid discharge. At the same time, the spray pipe 290 of the spray device sprays the waste battery to reduce the volatilization amount and temperature of the electrolyte during the puncture process;

[0046] 5. If Figure 2 As shown, after the puncture short circuit is completed, the piercing head 300 moves upward, the spraying device stops spraying, and the waste batteries on the piercing head 300 fall down under the blockage of the fixing plate 410 and fall freely to the bottom of the first chamber 210. At the same time, the residual electrolyte and the spraying water in the puncture process flow into the second chamber 500 through the second through hole 211 for collection;

[0047] 6. If Figure 2 As shown, the vacuum is broken in the first chamber 210 through the vacuum port 201, the atmospheric pressure outside the fixing member 230 disappears, and the pusher 240 drives the waste battery that has completed short-circuit discharge to move and push the fixing member 230 away, so that the waste battery enters the water tank 100 through the connecting hole 220, and further collects the electrolyte and discharges;

[0048] 7. At the same time, the next cycle of discharge operation can be carried out, that is, the door body 260 is opened, the used batteries are put in, and then the door body 260 is closed, and then the puncture discharge is carried out.
