Description

Technical Field

The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0035] like Figures 1 to 3 As shown, a battery discharge device 10 of an embodiment includes a discharge mechanism 100, an electrolytic cell 200 and a conductor 300. The discharge mechanism 100 includes a base 110, a first terminal 120, a second terminal 130, a first metal sheet 140, a second metal sheet 150 and a spiral pitch adjusting member 160. The first terminal 120 is movably connected to the base 110, the second terminal 130 is installed on the base 110, the first metal sheet 140 is connected to the first terminal 120, the second metal sheet 150 is connected to the second terminal 130, and the first metal sheet 140 is connected to the first terminal 120. 0 is used to abut against the positive electrode of the battery, the second metal sheet 150 is used to abut against the negative electrode of the battery, the second terminal 130 is sleeved on the spiral pitch adjusting member 160, and the spiral pitch adjusting member 160 is provided with a screw connection portion 163 at one end adjacent to the first terminal 120. The first terminal 120 is provided with a threaded hole, and the screw connection portion 163 is penetrated in the threaded hole and screwed with the first terminal 120, so that when the spiral pitch adjusting member 160 rotates, the first terminal 120 is close to or away from the second terminal 130, thereby adjusting the distance between the first metal sheet 140 and the second metal sheet 150.

[0036] Furthermore, the electrolytic cell 200 includes a cell body 210, an anode plate 220 and a cathode plate 230, the anode plate 220 is installed on the cell body 210, the cathode plate 230 is installed on the cell body 210, the wire 300 includes a first wire unit 310 and a second wire unit 320, the first terminal 120 is electrically connected to the cathode plate 230 through the first wire unit 310, and the second terminal 130 is electrically connected to the anode plate 220 through the second wire unit 320, so that current passes through the cathode plate 230 and the anode plate 220.

[0037] In this embodiment, the spiral pitch adjusting member 160 is provided with a screw connection portion 163, and the first terminal 120 is provided with a threaded hole, which is adapted to the threaded connection portion 163, and the threaded hole is screwed with the threaded connection portion 163, so that the first terminal 120 performs linear motion when the spiral pitch adjusting member 160 rotates. The second terminal 130 is sleeved on the spiral pitch adjusting member 160 and is rotatably connected with the spiral pitch adjusting member 160. When the spiral pitch adjusting member 160 rotates, the second terminal 130 does not perform linear motion. In this way, the first terminal 120 performs linear reciprocating motion along the horizontal plane, thereby adjusting the distance between the first metal sheet 140 and the second metal sheet 150 on the first terminal 120. Further, the first metal sheet 140 abuts against the positive electrode of the battery, and the second metal sheet 150 abuts against the negative electrode of the battery. By adjusting the distance between the first metal sheet 140 and the second metal sheet 150, the size of different batteries can be adapted. Furthermore, the tank body 210 is filled with a solution. When the battery is in contact with the first metal sheet 140 and the second metal sheet 150 to form a loop, current passes through the electrolytic cell 200, and an oxidation-reduction reaction occurs in the tank body 210 to produce the desired product, thereby achieving deep utilization of the residual electrical energy of the battery.

[0038] In the battery discharge device 10, the first terminal 120 is movably connected to the base 110, the first metal sheet 140 is connected to the first terminal 120, the second terminal 130 is installed on the base 110, the second metal sheet 150 is connected to the second terminal 130, and the first terminal 120 is provided with a threaded hole, and the screw adjustment member 160 is provided with a screw connection portion 163, and the threaded hole and the screw connection portion 163 are screwed, so that when the screw adjustment member rotates, the first terminal 120 performs linear motion, thereby adjusting the first metal sheet 140. The distance from the second metal sheet 150 is adapted to the electrode spacing of batteries of different models and specifications, thereby improving the applicability of the device; since the anode plate 220 and the cathode plate 230 are installed in the tank body 210, the cathode plate 230 is connected to the first terminal 120 through the first wire unit 310, and the anode plate 220 is connected to the second terminal 130 through the second wire unit 320, the residual power of the battery can be used in the electrolytic cell 200 while discharging the battery, thereby realizing deep recycling of the battery.

[0039] like Figure 2 and Figure 3As shown, in one embodiment, the base 110 is provided with a guide rail 111, and the first terminal 120 includes a first terminal body 121, a first connecting member 122 and a first clamping member 123. The first connecting member 122 is fixedly connected to the top of the first terminal body 121, the first clamping member is fixedly connected to the bottom of the first terminal body, a threaded hole is provided in the first connecting member 122, and the first clamping member 123 is slidably connected to the guide rail 111, so that the first clamping member 123 moves along the guide rail 111 when the spiral distance adjusting member 160 rotates. In this embodiment, when the spiral distance adjusting member 160 rotates, the first connecting member 122 performs linear motion, and the first clamping member 123 is slidably connected to the guide rail 111, so that the first terminal body 121 moves along the extension direction of the guide rail 111 to adjust the distance between the first metal sheet 140 and the second metal sheet 150.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, the second terminal 130 includes a second terminal body 131, a second connecting member 132 and a second clamping member 133, the second connecting member 132 is fixedly connected to the top of the second terminal body 131, the second clamping member is fixedly connected to the bottom of the second terminal body 131, the second connecting member 132 is provided with a sleeve hole, the spiral pitch adjusting member 160 passes through the sleeve hole and is rotatably connected to the second connecting member 132, and the second clamping member 133 is clamped to the guide rail 111. In this embodiment, the spiral pitch adjusting member 160 passes through the sleeve hole and is rotatably connected to the second connecting member 132, so that the second connecting member 132 is sleeved on the spiral pitch adjusting member 160, so that the second terminal body 131 does not perform linear movement when the spiral pitch adjusting member 160 rotates. Further, the second clamping member 133 is clamped to the guide rail 111, so that the first metal sheet 140 and the second metal sheet 150 are located on the same horizontal plane. Furthermore, since the second terminal body 131 does not need to perform linear motion relative to the guide rail, the second clamping member 133 may be welded to the guide rail 111 to ensure the structural stability of the second clamping member 133 and the guide rail 111 .

[0041] However, when the base 110 collides, the battery is prone to tipping over, resulting in a problem of battery discharge interruption. Figure 1 As shown, in one embodiment, the battery discharge device 10 further includes an anti-flip baffle 400, the number of the anti-flip baffles 400 is two, the two anti-flip baffles 400 are both installed on the base 110, and the first metal sheet 140 and the second metal sheet 150 are both located between the two anti-flip baffles 400. It can be understood that the positive and negative electrodes of the battery are respectively abutted against the first metal sheet 140 and the second metal sheet 150, and the anti-flip baffles 400 are respectively provided on both sides of the first metal sheet 140 and the second metal sheet 150 to prevent the battery from tipping over.

[0042] like Figure 1 As shown, in one embodiment, the number of the first metal sheet 140 is multiple, the number of the second metal sheet 150 is multiple, the number of the anti-turnover baffle 400 is multiple, the multiple first metal sheets 140 are arranged at intervals along the length direction of the first terminal 120, and the multiple second metal sheets 150 are arranged at intervals along the length direction of the second terminal 130. The multiple first metal sheets 140 and the multiple second metal sheets 150 are arranged one by one to form multiple discharge metal sheet groups, and each of the discharge metal sheet groups is arranged between two adjacent anti-turnover baffles 400. It can be understood that multiple first metal sheets 140 are arranged on the first terminal 120, and multiple second metal sheets 150 are arranged on the second terminal 130. Multiple discharge metal sheet groups can discharge multiple batteries at the same time, thereby improving the average discharge efficiency of a single battery. Further, anti-turnover baffles 400 are respectively arranged on both sides of each discharge metal sheet group to prevent the battery from tipping over.

[0043] like Figure 3 As shown, in one embodiment, the spiral pitch adjusting member 160 includes a spiral pitch adjusting rod 161 and a rotating handle 162, one end of the spiral pitch adjusting rod 161 is fixedly connected to the rotating handle 162, and a screw connection portion 163 is provided at the other end of the spiral pitch adjusting rod 161. In this embodiment, the spiral pitch adjusting rod 161 is rotated by rotating the rotating handle 162, thereby causing the first terminal body 121 to perform linear motion.

[0044] like Figure 1 As shown, in one embodiment, a steering wheel 500 is provided at the bottom of the base 110. It can be understood that the waste lithium-ion battery is heavy and cannot be bumped at will. By providing a steering wheel 500 at the bottom of the base 110, it is convenient to move the operation and the battery discharge position, thereby improving the convenience of the discharge operation. Further, the steering wheel can be fixed to the bottom of the base 100 by screwing.

[0045] like Figure 1 As shown, in one embodiment, the battery discharge device 10 further includes an exhaust fan 600, which is installed on the base 110. It can be understood that when the positive and negative electrodes of the battery are respectively in contact with the first metal sheet 140 and the second metal sheet 150 for discharge, there is heat release, and the exhaust fan 600 is used to dissipate heat from the battery to improve the safety of battery discharge. Furthermore, an exhaust channel and a plurality of exhaust holes 112 are provided on the base 110, and the plurality of exhaust holes 112 are all connected to the exhaust channel, and the plurality of exhaust holes 112 are exposed on the top surface of the base 110, so that the exhaust fan 600 can dissipate heat from the battery when it is working.

[0046] like Figure 1 As shown, in one embodiment, the battery discharge device 10 further includes an ammeter 700 , and the ammeter 700 is electrically connected to the first wire unit 310 .

[0047] In one embodiment, the battery discharge device 10 further includes a heating resistor 800 , and the heating resistor 800 is electrically connected to the first wire unit 310 and the second wire unit 320 .

[0048] In this embodiment, the heating resistor 800 is a resistor with adjustable resistance. The current of the loop is detected in real time by the ammeter 700, and the current in the electrolytic cell 200 is adjusted by adjusting the resistance of the heating resistor 800, which is beneficial to efficient electrolysis operation of the battery.

[0049] The present application also provides a battery recycling device, comprising the battery discharge device 10 of any of the above embodiments.

[0053] 2. Since the anode plate 220 and the cathode plate 230 are installed in the tank body 210, the cathode plate 230 is connected to the first terminal 120 through the first wire unit 310, and the anode plate 220 is connected to the second terminal 130 through the second wire unit 320, the residual electric energy of the battery can be used in the electrolytic cell 200 while the battery is discharged, thereby realizing deep recycling of the battery;
