A first conductive sheet 210 is arranged on the side of the cover 200 close to the discharge container 100, and an electrically controlled magnetic attraction device 220 is arranged on the side of the cover 200 away from the discharge container 100. The working area of the electrically controlled magnetic attraction device 220 is greater than or equal to the area of the first conductive sheet 210. The discharge container 100 includes a shell 110, a conductive layer 120 and a lining 130 which are sequentially sleeved together from the outside to the inside, and the shell 110, the conductive layer 120 and the lining 130 are insulated from each other. A second conductive sheet 140 is arranged on the inner bottom surface of the discharge container 100, and the second conductive sheet 140 and the first conductive sheet 210 are arranged opposite to each other. Figure 4 Shows Figure 3 The enlarged structural diagram of the A area in the middle, the second conductive sheet 140 passes through the liner 130 and connects with the conductive layer 120; Figure 5 Shows Figure 3 In the enlarged structural diagram of the B area, when the cover body 200 is in the closed state, the first conductive sheet 210 and the conductive layer 120 are connected.
[0031] Figure 6The schematic diagram of the working structure of the semi-insertion battery discharge device in the embodiment of the utility model is shown. When using the semi-insertion battery discharge device of the utility model, a proper amount of conductive particles 10 are put into the discharge container 100; then one end of the retired cylindrical lithium battery 20 is adsorbed on the first conductive sheet 210 by the electrically controlled magnetic suction device 220, and then the other end of the retired cylindrical lithium battery 20 is inserted into the conductive particles 10; when the cover body 200 is closed, the first conductive sheet 210 and the conductive layer 120 are connected, so that the retired cylindrical lithium battery 20, the first conductive sheet 210, the conductive layer 120, and the second conductive sheet 220 are connected. The conductive sheet 140 and the conductive particles 10 form a discharge circuit, and the retired cylindrical lithium batteries 20 begin to discharge; after the discharge is completed, the retired cylindrical lithium batteries 20 are all lifted up by the electrically controlled magnetic suction device 220, and can be easily unloaded; the whole process does not require the conductive particles 10 and the retired cylindrical lithium batteries 20 to be mixed, pressurized or screened, that is, the conductive particles 10 are placed in the discharge container 100 and basically do not move, which reduces friction, collision and extrusion, and can effectively avoid the conductive particles 10 from shedding and generating dust, which is beneficial to increasing the service life of the conductive particles 10 and keeping the retired cylindrical lithium batteries 20 clean.
[0032] In addition, during the discharge process, the electrically controlled magnetic attraction device 220 can release the magnetic attraction at any time, and then the discharge process can be terminated by lifting the cover body 200, which is safe and reliable.
[0033] Specifically, the discharge container 100 is provided with conductive particles 10 , and the conductive particles 10 cover the second conductive sheet 140 ; the conductive particles 10 are graphite particles or carbon black particles, which can effectively consume the power of the retired cylindrical lithium battery 20 .
[0034] Furthermore, the electrically controlled magnetic suction device 220 is a suction cup type electromagnet, which has stable operation, strong suction force, and small residual magnetism, and can easily adsorb and unload retired cylindrical lithium batteries 20.
[0035] In some specific embodiments, see Figure 2 The inner lining 130 is provided with a plurality of rows of first air holes 131, the conductive layer 120 is vertically provided with a plurality of long strip air holes 121, and the outer shell 110 is provided with a plurality of rows of second air holes 111. The diameter of the first air holes 131 is smaller than the diameter of the second air holes 111, and the width of the long strip air windows 121 is larger than the diameter of the second air holes 111, so as to facilitate heat dissipation during the discharge process. Heat can be dissipated to the outside through the first air holes 131, the long strip air windows 121 and the second air holes 111.
[0036] Specifically, the plurality of rows of second air holes 111 and the plurality of long strip air windows 121 are arranged in one-to-one correspondence to form a smooth heat dissipation channel, which can effectively improve the heat dissipation efficiency; in addition, a fan can be placed outside the semi-insertion battery discharge device to blow, which has an excellent heat dissipation effect.
[0037] Furthermore, the diameter of the first air hole 131 is less than 5 mm. The diameter of the first air hole 131 is relatively small, which can prevent the conductive particles 10 from passing through the lining 130 while facilitating heat dissipation; the diameter of the second air hole 111 is in the range of 2 to 4 cm, and the width of the elongated air window 121 is in the range of 6 to 10 cm, which is convenient for air circulation and beneficial for heat dissipation.
[0038] In some specific embodiments, the material of the lining 130 is a silicone rubber glass fiber composite cloth, which is resistant to high temperature, has good strength, corrosion resistance, heat aging resistance and high insulation performance, and is very suitable for use in the discharge container 100; the material of the conductive layer 120 is a copper-aluminum alloy, which has excellent conductivity, high strength, corrosion resistance and heat resistance, and can form a good support for the lining 130; the surface of the conductive layer 120 is coated with an insulating paint layer (there is no insulating paint layer in the area connected to the first conductive sheet 210 and the second conductive sheet 140) to prevent the current from not passing through the second conductive sheet 140; the material of the outer shell 110 is stainless steel, which is strong, durable and corrosion-resistant; the materials of the first conductive sheet 210 and the second conductive sheet 140 are both copper-aluminum alloy, which has excellent conductivity and is strong and durable.
[0039] In some specific embodiments, the inner diameter of the discharge container 100 ranges from 50 to 120 cm, which is easy to match with a suitable electrically controlled magnetic suction device 220; the height of the discharge container 100 ranges from 60 to 150 cm, which is compatible with retired cylindrical lithium batteries 20 of various specifications.
[0040] In some specific embodiments, see Figure 2 A plurality of protrusions 211 are formed on one side of the first conductive sheet 210 close to the discharge container 100 , which is beneficial to improving the contact between the first conductive sheet 210 and the retired cylindrical lithium battery 20 .
[0041] In some specific embodiments, at least two temperature sensors are disposed inside the discharge vessel 100 to monitor the temperature during the discharge process.
[0042] In some specific embodiments, see Figure 1 A connecting rod 230 is provided on one side of the cover body 200 away from the discharge container 100 , which is used to connect a robotic arm to control the lifting and horizontal rotation of the cover body 200 , so as to facilitate the suction, insertion, and unloading of the retired cylindrical lithium batteries 20 .
[0043] The working process of the semi-insertion battery discharge device of the utility model is as follows:
[0044] See also Figure 6 First, put a proper amount of conductive particles 10 into the discharge container 100; then, one end of the retired cylindrical lithium battery 20 is adsorbed on the first conductive sheet 210 by the electrically controlled magnetic suction device 220, and then the other end of the retired cylindrical lithium battery 20 is inserted into the conductive particles 10; when the cover 200 is closed, the first conductive sheet 210 and the conductive layer 120 are connected, so that the retired cylindrical lithium battery 20, the first conductive sheet 210, the conductive layer 120, the second conductive sheet 140 and the conductive particles 10 form a discharge circuit, and the retired cylindrical lithium battery 20 begins to discharge; after the discharge is completed, the retired cylindrical lithium battery 20 is completely lifted up by the electrically controlled magnetic suction device 220, and the material can be easily unloaded.
[0045] The semi-insertion battery discharge device of the utility model is used to discharge the retired cylindrical lithium battery 20. The entire operation process does not require mixing, pressurizing or screening the conductive particles 10 and the retired cylindrical lithium battery 20, that is, the conductive particles 10 are placed in the discharge container 100 and basically do not move, which reduces friction, collision and extrusion, and can effectively prevent the conductive particles 10 from falling off and generating dust, which is beneficial to improving the service life of the conductive particles 10 and keeping the retired cylindrical lithium battery 20 clean. In addition, during the discharge process, the electrically controlled magnetic attraction device 220 can release the magnetic attraction at any time, and then the cover 200 can be lifted to terminate the discharge process, which is safe and reliable.
