[0033] like Figures 1 to 4 As shown, the present application provides a battery discharge device, and an embodiment of the battery discharge device includes: a liquid storage tank 10 and a puncture device 20. The liquid storage tank 10 is provided with a liquid storage cavity inside, and a feeding port 11 is provided on the liquid storage tank 10. The puncture device 20 is arranged in the liquid storage cavity, and the puncture device 20 includes a receiving box 21 connected to the liquid storage tank 10 and a pair of puncture components 22 arranged on opposite sides of the receiving box 21, wherein a receiving space connected to the feeding port 11 is provided inside the receiving box 21, and the receiving space can accommodate batteries, and through holes for the pair of puncture components 22 to pass through are provided on opposite sides of the receiving box 21, and the pair of puncture components 22 can be movably arranged, and have a pressing position close to each other to puncture the battery and a avoidance position away from each other to stay away from the battery.

[0034] By applying the technical solution of this embodiment, water is contained in the liquid storage cavity, and the water can enter the storage box 21. The storage space can accommodate batteries, and the water in the storage box 21 can soak the batteries to avoid the heat release phenomenon generated by the batteries when the batteries are punctured later. The opposite sides of the storage box 21 are provided with through holes for a pair of puncture components 22 to pass through. The pair of puncture components 22 are movably arranged and have a squeeze position close to each other to puncture the battery and a avoidance position away from each other to stay away from the battery. In this way, when the pair of puncture components 22 are in the squeeze position, the opposite sides of the battery are punctured, and the water in the liquid storage cavity enters the interior of the battery from the opposite sides of the battery, and the electrolyte in the battery is discharged faster, which improves the efficiency of the battery discharge operation. Therefore, the technical solution of the present application effectively solves the problem of slow discharge efficiency of battery discharge equipment in the related art.

[0035] When the pair of puncture components 22 are in the squeezed position, the opposite sides of the battery are punctured, so that the battery is physically short-circuited, the battery discharge rate is increased, and the generation of waste water is reduced.

[0036] The batteries in the container 21 include cylindrical, soft-pack and square batteries. There can be one or more batteries, and two puncture devices 20 are staggered. In this way, the production is unitized, and local and overall hierarchical operation management can be carried out, which is convenient for adjusting the battery processing capacity as needed, and is convenient for management and monitoring.

[0037] like Figures 1 to 4 As shown, in order to ensure that the two puncture assemblies 22 pierce from opposite sides of the battery, each puncture assembly 22 includes a first driving cylinder arranged on the inner wall of the liquid storage tank 10, a mounting plate 221 arranged on the first telescopic rod of the first driving cylinder, and a puncture needle 222 arranged on the mounting plate 221. The through hole is for the puncture needle 222 to pass through. When the first telescopic rods of a pair of puncture assemblies 22 are extended, the pair of puncture needles 222 are driven to approach each other, and when the first telescopic rods of a pair of puncture assemblies 22 are retracted, the pair of puncture needles 222 are driven to move away from each other. A high temperature resistant coating is added to the puncture needle 222.

[0038] like Figures 1 to 4 As shown, a cover plate 12 capable of opening and closing the feeding port 11 is provided on the top of the storage box 21. When the cover plate opens the feeding port 11, the battery can be put into the storage box 21 from the feeding port 11. When the cover plate closes the feeding port 11, the gas in the storage box 21 will not be discharged from the feeding port 11. A first feeding port is provided at the bottom of the storage box 21, and a blocking member 23 capable of opening and closing the first feeding port is also provided at the bottom of the storage box 21. When the blocking member 23 opens the first feeding port, the punctured battery can fall out of the first feeding port, and when the blocking member 23 closes the first feeding port, the blocking member can support the battery to prevent the battery from falling out of the first feeding port. The blocking member is preferably a blocking plate.

[0039] like Figures 1 to 4 As shown, in order to facilitate opening and closing of the first blanking port, the blocking member 23 is slidably arranged at the bottom of the accommodating box 21, and the battery discharge device also includes a second driving cylinder arranged on the inner wall of the liquid storage tank 10, and the second telescopic rod of the second driving cylinder is connected to the end of the blocking member 23, and the second telescopic rod of the second driving cylinder is telescoped to drive the blocking member 23 to slide.

[0040] Specifically, slide grooves are provided on opposite sides of the first blanking opening, and two sides of the blocking plate are inserted into the slide grooves so that the blocking plate slides on the bottom of the containing box 21 .

[0041] like Figures 1 to 3As shown, the battery discharge device also includes a lifting and transporting device 30 and a vibrating dehydrating device 40. The first end of the lifting and transporting device 30 is located below the puncturing device 20, and the vibrating dehydrating device 40 is located below the second end of the lifting and transporting device 30. The vibrating dehydrating device 40 includes a vibrator and a first drain pipe connected to the vibrator, and the first drain pipe is connected to the liquid storage tank 10. The setting of the lifting and transporting device 30 can transport the punctured battery dropped from the first drop port to the vibrator. Since the lifting and transporting device 30 adopts a lifting and transporting method, when the lifting and transporting device 30 lifts the punctured battery, the water on the punctured battery can flow down and flow back to the liquid storage tank 10. Under the vibration of the vibrator, most of the water on the surface of the punctured battery on the vibrator is separated from the battery and discharged back to the liquid storage tank 10 from the first drain pipe.

[0042] like Figures 1 to 3 As shown, the vibration dehydration device 40 also includes a dehydration screen connected to the vibration machine. The dehydration screen is used to place batteries and help dehydrate the batteries through the vibration of the vibration machine.

[0043] like Figures 1 to 3 As shown, the battery discharge device also includes an air drying device 50 arranged downstream of the vibration dehydration device 40, and the air drying device 50 includes a first shell, a mesh chain conveyor belt arranged in the first shell, and an air suction port arranged on the first shell. The first shell is also provided with a second drop port corresponding to the vibrator. The air drying device 50 also includes a second drain pipe arranged on the bottom wall of the first shell, and the second drain pipe is connected to the liquid storage tank 10. After the vibration dehydration device 40 dehydrates the battery, it is conveyed to the mesh chain conveyor belt. Due to the effect of the air suction port, a negative pressure is formed in the first shell, and the negative pressure carries airflow, which dries the surroundings of the battery. During the air drying process, the water separated from the battery is discharged back to the liquid storage tank 10 through the second drain pipe. The air-dried battery can be sent to a baler and packaged by the baler.

[0044] The first shell is also provided with an air inlet connected to an air compressor, so that the interior of the first shell can be kept in a negative pressure state by compressed air provided from the outside.

[0045] like Figures 1 to 3As shown, the lifting and transporting device 30 includes a second shell 31 and a lifting and transporting machine arranged in the second shell 31. One end of the second shell 31 located below the puncture device 20 extends into the liquid storage tank 10. The bottom wall of the second shell 31 is tilted upward, and a third drop opening connected to the vibration dehydration device 40 is arranged on the bottom wall of the second shell 31. The lifting and transporting machine can transport the punctured battery dropped out of the first drop opening to the vibration dehydration device 40 through the third drop opening. The battery dropped out of the first drop opening will carry a certain amount of water. During the process of the lifting and transporting battery by the lifting and transporting machine, part of the water will fall to the bottom wall of the second shell 31 due to the effect of gravity, and flow back to the liquid storage tank 10 through the bottom wall of the second shell 31.

[0046] like Figures 1 to 3 As shown, an opening 311 is provided on the top wall of the second shell 31, and the opening 311 corresponds to the upper surface of the lifting conveyor. The battery discharge device also includes a spray cooling device 60 located downstream of the puncture device 20, and the spray cooling device 60 includes an outer cover 61 connected to the liquid storage tank 10, a first spray pipe 62 arranged on the inner top wall of the outer cover 61, and a liquid collecting tank 63 arranged below the outer cover 61. The spray hole on the first spray pipe 62 is located directly above the opening 311, the liquid collecting tank 63 is connected to the liquid storage tank 10, and the bottom wall of the liquid collecting tank 63 is inclined upward relative to the bottom wall of the liquid storage tank 10. The punctured battery will generate a certain amount of heat. When the lifting conveyor is lifting and transporting the battery, the spray liquid in the first spray pipe 62 falls from the spray hole into the opening 311, and sprays the battery passing under the opening 311 for cooling treatment. A part of the spray liquid after cooling treatment flows back from the bottom wall of the second shell 31 to the liquid storage tank 10, and the other part flows back from the liquid collecting tank 63 to the liquid storage tank 10.

[0047] It should be noted that the outer cover 61, the liquid collecting box 63 and the liquid storage box 10 together form a sealed space.

The punctured battery will generate waste gas (such as hydrogen). During the process of lifting and transporting the battery by the lifting and transporting device 30, the waste gas in the lifting and transporting device 30 can enter the collecting tube 71 from the first collecting port 72. During the process of the spray cooling device 60 spraying the battery for cooling treatment, the waste gas in the outer cover 61 can enter the collecting tube 71 from the second collecting port 73. During the process of the air drying device 50 air drying the battery, the waste gas in the air drying device 50 can enter the collecting tube 71 from the air intake port and the third collecting port 74. The waste gas in the collecting tube 71 can be discharged from the exhaust port 75 to the spray purification device 80 for spray purification treatment.

[0049] Specifically, when the battery is punctured to achieve discharge, the electrolyte in the battery will generate hydrogen and oxygen, and the hydrogen will float up and gather on the top of the lifting and transporting device 30 and the outer cover 61. The collecting pipe 71 will collect the hydrogen and extract the hydrogen to the spray purification device 80 through the collecting pipe 71. A plurality of hydrogen concentration monitoring points are arranged on the inner top wall of the outer cover 61. When the hydrogen concentration reaches 1%, the exhaust speed of the collecting pipe 71 is increased, and a large amount of hydrogen is extracted, thereby reducing the hydrogen concentration inside the outer cover 61 and the liquid storage tank 10, and controlling the hydrogen concentration to be below 1% in real time to ensure production safety.

[0050] like Figures 1 to 3 As shown, the spray purification device 80 includes a spray tower 81, a second spray pipe arranged in the spray tower 81, and the spray purification device 80 also includes a sterilizer 82, a filter 83 and an exhaust pipe 84.

The spray purification device 80 also includes a fan arranged between the filter 83 and the exhaust pipe 84 to generate negative pressure in the collection pipe 71 and the above-mentioned air intake port.

[0051] The sterilizer 82 is preferably an ultraviolet sterilizer. The filter 83 is preferably an activated carbon box.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
