Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crushing waste batteries, in particular to an equipment and process for dry crushing waste batteries without fire. BACKGROUND

[0002] Waste batteries refer to batteries that have lost their value or cannot be recharged, including dry batteries and rechargeable batteries. Dry batteries are usually composed of a circular battery shell, which contains a carbon rod inside. The electrolyte (manganese dioxide, etc.) is arranged around the carbon rod inside the battery shell. The positive and negative terminals are arranged at both ends of the battery shell, and the positive terminal is in contact with the carbon rod. There is a certain gap between the electrolyte and the positive terminal. Waste batteries usually contain harmful metal elements or chemical substances, which can cause damage to the environment and health if not properly treated. Therefore, it is very important to properly recycle and dispose of waste batteries to reduce environmental pollution and achieve effective resource reuse.

[0003] During the recycling process of waste batteries, they need to be crushed first to recover the electrolyte, terminals, battery shells and carbon rods inside the waste batteries.

[0004] For example, the patent application with publication number CN219483737U discloses a waste battery crushing and separating recovery mechanism, which includes a separating and recycling box. The inner wall of the separating and recycling box is fixedly installed with a receiving and conveying box. The bottom end of the separating and recycling box is provided with a separating mechanism. The inside of the receiving and conveying box is provided with a conveying mechanism. The waste battery crushing and separating recovery mechanism can achieve the effect of receiving and crushing the shell of the waste battery by the separating mechanism and the conveying mechanism. The shell is controlled to be conveyed by the conveying roller. At the same time, the separating roller of the separating mechanism rotates and reciprocates to scrape the crushed shell, thereby enhancing the separation effect and making the separation complete and convenient for recycling and utilization. The separation and recovery efficiency is high.

[0005] The above-mentioned prior art still has the following problems when crushing and separating waste batteries: the above-mentioned prior art needs to crush and separate waste batteries. In order to make the waste battery shell completely crushed by external force, a large pressure needs to be applied to the waste battery shell. Therefore, the pressure on the waste battery shell is large, the electrolyte inside the waste battery reacts intensively under pressure, and the waste battery may explode. Moreover, the above-mentioned prior art does not detect the electricity of the waste battery when crushing it. If the remaining electricity of the waste battery is relatively large, the possibility of short circuit of the internal circuit of the waste battery due to external force deformation during the crushing process of the waste battery is further increased, thereby increasing the degree of explosion of the waste battery and the risk.

[0006] Moreover, the prior art does not classify each part of the waste battery during the crushing and separation, so that the components of the waste battery after crushing and separation are mixed together, which is not easy to classify and recycle, and each part of the waste battery is severely damaged (such as the cutting of the battery shell and carbon rod, and the scattering of the electrolyte), which affects the crushing and separation effect of the waste battery.

DETAILED DESCRIPTION

[0044] The following will be described in detail below with reference to the accompanying drawings. Figures 1 to 12 The present application will be further described in detail.

[0045] The present application discloses an equipment and process for dry crushing of waste batteries without fire, which can gradually insert and crush the waste batteries, reduce the accumulation of waste battery parts after crushing, and reduce the possibility of explosion during the crushing process. EMBODIMENT

[0046] Referring to Figure 1 An equipment for dry crushing of waste batteries without fire, comprising symmetrically arranged conveying belts 1, each of which is provided with a plurality of uniformly distributed arc-shaped grooves 11, and the arc-shaped grooves 11 on the two conveying belts 1 correspond one by one, and detection zones, terminal removal zones and internal material removal zones are sequentially arranged between the two conveying belts 1 along the length direction.

[0047] The circular through groove composed of the arc-shaped grooves 11 corresponding to the adjacent parts of the conveying belt 1 can clamp the waste battery 100, and the diameter of the circular through groove is slightly smaller than the diameter of the waste battery 100, so as to ensure that the conveying belt 1 gives the waste battery 100 a holding force when clamping and conveying the waste battery 100, avoiding the waste battery 100 from falling off the conveying belt 1. The conveying belt 1 is made of rubber material, so the contact area between the conveying belt 1 and the waste battery 100 is larger when clamping the waste battery 100, and the clamping is more stable. A relief inclined surface is also provided on the arc-shaped groove 11 to guide the waste battery 100 when it is inserted into the circular through groove, so that the waste battery 100 can be smoothly inserted into the circular through groove.

[0048] Referring to Figure 1The top conveying belt 1 is provided with support frame one 12 symmetrical along the width direction of the conveying belt 1 on both sides, and the bottom conveying belt 1 is provided with support frame two 13 symmetrical along the width direction of the conveying belt 1 on both sides. The support frames corresponding to the same conveying belt 1 are jointly installed with pulleys 14 matched with the corresponding conveying belt 1 through bearings between both ends of the support frames. Any two adjacent pulleys 14 are connected through driving gears. The support frame one 12 and the support frame two 13 close to the driving gear are jointly installed with a vertical rod 15, and the vertical rod 15 is installed with a limiting round rod 16 for limiting the waste battery 100.

[0049] The waste battery 100 is placed between the two arc-shaped grooves 11 of the conveying belt 1 close to the driving gear. The area closest to the driving gear is the loading area, that is, the waste battery 100 is clamped in the circular groove in the loading area. When the clamping of the waste battery 100 is completed, the step motor drives any pulley 14 close to the driving gear to rotate at this time. The pulley 14 drives the adjacent pulley 14 to rotate through the driving gear during rotation. The two pulleys 14 drive the conveying belt 1 to intermittently drive through the cooperation of the remaining two pulleys 14. The waste battery 100 is driven into the detection area during the intermittent driving of the conveying belt 1. At this time, there is no waste battery 100 in the circular groove corresponding to the loading area. The waste battery 100 is placed in the circular groove closest to the driving gear by artificial means. The step motor can drive the waste battery 100 during the conveying of the conveying belt 1 to accurately enter the detection area, the terminal removal area and the internal material removal area.

[0050] The vertical rod 15 and the limiting round rod 16 cooperate to limit the waste battery 100 placed in the loading area, so that the waste battery 100 conveyed by the conveying belt 1 has both ends located on the same vertical plane, which facilitates the subsequent equipment parts to enter the inside of the waste battery 100.

[0051] Referring to Figure 1 And Figure 3 The detection mechanism 2 is arranged in the detection area and includes a conductive U-shaped rod 21. The two vertical sections of the conductive U-shaped rod 21 are provided with electric contacts 22 at the ends.

[0052] An alarm 23 is arranged on the horizontal section of the conductive U-shaped rod 21 and is connected in series in the closed circuit composed of the conductive U-shaped rod 21, the electric contacts 22 and the waste battery 100.

[0053] The electrically-conductive -type rod 21 is a metal rod and has electrical conductivity. It should be noted that if the battery 100 has a low power, the alarm 23 will alarm, which means that the battery 100 can enter the terminal removal area. Otherwise, the battery 100 cannot enter the terminal removal area and needs to be removed from the conveyor belt 1. In addition, it should be further explained that the alarm 23 has a very low alarm power. In actual work, when the conveyor belt 1 sends the battery 100 between the two vertical sections of the electrically-conductive -type rod 21, the positive and negative electrodes of the battery 100 are in contact with the corresponding electric contacts 22. At this time, the electrically-conductive -type rod 21, the electric contacts 22, the battery 100 and the alarm 23 form a closed loop. If the battery 100 has a low power, that is, the battery 100 has a power lower than the alarm power required by the alarm 23, the alarm 23 does not alarm, and the conveyor belt 1 continues to convey the battery 100 for the next step.

[0054] With reference to Figure 3 The horizontal section of the electrically-conductive -type rod 21 is installed at the bottom of the support frame 12 away from the drive gear. The support frame 13 away from the drive gear is provided with a telescopic cylinder 211 through a cylinder seat, and the telescopic cylinder 211 is located between the -type frame 137 and the vertical plate 3. The vertical frame 212 is installed at the bottom of the support frame 12 away from the drive gear. The vertical frame 212 is provided with a linkage rod 213 sliding along the length direction. The conveyor belt 1 corresponding to the support frame 12 and away from the drive gear is provided with an annular groove 214 extending along the length of the conveyor belt 1. A section of the linkage rod 213 close to the drive gear abuts against the inside of the annular groove 214. The telescopic cylinder 211 is provided with a push plate 215 at the telescopic end. The push plate 215 is provided with a guide inclined surface close to the conveyor belt 1 and matched with the linkage rod 213.

[0055] If the waste battery 100 has a higher power than the alarm required by the alarm 23, the alarm 23 will alarm at this time, and the conveying belt 1 will not continue to send the waste battery 100 into the terminal area for processing, that is, the waste battery 100 in the detection area needs to be discharged outward, at this time the telescopic cylinder 211 is started, the telescopic end of the telescopic cylinder 211 drives the push plate 215 to move to one side of the conveying belt 1, it is need to be explained that the push plate 215 guiding slope contacts the linkage rod 213 first during the movement of the push plate 215, and then the push plate 215 abuts against the waste battery 100, specifically, when the push plate 215 guiding slope abuts against the linkage rod 213, the linkage rod 213 moves upward along the guiding slope at this time due to the blocking of the push plate 215 guiding slope, and the linkage rod 213 moves upward in the vertical frame 212 and cooperates with the annular groove 214 to drive the conveying belt 1 to move slightly by a displacement at this time, at this time the conveying belt 1 part corresponding to the waste battery 100 that needs to be discharged outward is lifted upward by a certain distance, that is, the circular groove corresponding to the waste battery 100 that needs to be discharged outward is opened, thereby ensuring that the waste battery 100 cannot be discharged due to the clamping between the waste battery 100 and the conveying belt 1 when the waste battery 100 is discharged subsequently.

[0056] When the linkage rod 213 completely passes over the guiding slope, the linkage rod 213 slides on the top of the push plate 215, and the linkage rod 213 no longer has displacement in the vertical direction, at this time the telescopic end of the telescopic cylinder 211 is quickly retracted to one side of the conveying belt 1, the telescopic end of the telescopic cylinder 211 gives the waste battery 100 a momentary thrust through the push plate 215, thereby the waste battery 100 with a higher power than the alarm power of the alarm 23 can be discharged outward, thereby avoiding the possibility of fire or even explosion when operating in the subsequent terminal area due to the high internal power of the waste battery 100.

[0057] The existing collection frame can collect and process the discharged waste battery 100.

[0058] Continuing to refer to Figure 3 , the terminal area is provided with a vertical plate 3, and the end of the vertical plate 3 away from the detection area is provided with a guide plate 31 inclined away from one side of the conveying belt 1.

[0059] The support frame two 13 away from the drive gear is provided with a supporting frame 32 symmetrically arranged along the length direction thereof, and the vertical plate 3 is installed on the two supporting frames 32, and the bottom of the support frame one 12 away from the drive gear is provided with a fixed connecting frame 33 in inverted T-shaped structure matched with the vertical plate 3, the vertical section of the fixed connecting frame 33 is installed on the corresponding support frame one 12, the horizontal section of the fixed connecting frame 33 is provided with a plurality of rolling rods 34 along the length direction thereof, and the side of the rolling rod 34 close to the conductive I-shaped rod 21 is provided with a guide slope.

[0060] Wherein the vertical plate 3 top height is slightly higher than the bottom height of the entering terminal removal area of the waste battery 100, and the bottom height of the rolling rod 34 is slightly lower than the top height of the entering terminal removal area of the waste battery 100, and in the specific work, the waste battery 100 whose electric quantity is lower than the alarm electric quantity after being detected in the detection area is conveyed into the terminal removal area through the conveying belt 1, and the waste battery 100 moves to the position between the rolling rod 34 and the vertical plate 3 during the conveying process, the vertical plate 3 can exert an external force on the positive terminal and the battery shell connection (i.e. the arrow position) of the waste battery 100, and then the external force can extrude the battery shell to separate the battery shell from the positive terminal, so that the battery shell and the positive terminal are separated by the slight extrusion of the vertical plate 3, so that the internal structure of the waste battery 100 is exposed, and the guide slope plays a guiding role on the waste battery 100 when the waste battery 100 enters the position between the rolling rod 34 and the vertical plate 3, facilitating the waste battery 100 to enter the bottom of the rolling rod 34. Figure 12

[0061] With the continuous movement of the conveying belt 1, the vertical plate 3 can extrude the circumference of the battery shell, and in the process of separating the battery shell from the positive terminal, the rolling rod 34 can provide a fulcrum for the vertical plate 3 when extruding the positive terminal and the battery shell connection through the fixed connecting frame 33, and can also slightly extrude and deform the battery shell, giving the battery shell an external force, so that the battery shell and the electrolyte are separated, avoiding the adhesion of the electrolyte in the waste battery 100 to the inside of the battery shell, and facilitating the subsequent removal of the electrolyte from the inside of the battery shell.

[0062] When the waste battery 100 moves out of the vertical plate 3 and contacts the guide plate 31, the positive terminal is blocked from moving away from the conveying belt 1 by the guide plate 31 at this time, and the battery shell will not move away from the conveying belt 1 due to the blocking of the vertical plate 3, and then the positive terminal and the battery shell are separated.

[0063] Wherein when the positive terminal contacts the guide plate 31, the indentation of the rolling rod 34 on the battery shell cooperates with the rolling rod 34 to also limit the battery shell, avoiding the possibility that the positive terminal will drive the battery shell to move when it falls off the battery shell through the guide plate 31.

[0064] Referring to Figure 1 and Figure 4 , the internal material removal area is provided with a material taking mechanism 4, which comprises: a clamping disc 41 provided in the internal material removal area, and a through circular groove provided in the center of the clamping disc 41 for accommodating the carbon rod.

[0065] Referring to Figure 5 , Figure 6 and Figure 7 , a clamping block 42 is uniformly provided around the clamping disc 41, which is used for clamping and limiting the carbon rod.​

[0066] The horizontal support 131 is installed on the support frame 13 away from the driving gear, and the moving frame 132 is slidingly arranged on the horizontal support 131. The horizontal frame 133 is arranged at one end of the moving frame 132 away from the horizontal support 131, and the clamping disc 41 is installed at one end of the horizontal frame 133 close to the conveying belt 1. The annular frame 134 is slidingly arranged on the horizontal frame 133 through the moving protrusion. The adjusting block 135 corresponding to the clamping block 42 is slidingly arranged on the end face of the clamping disc 41, and the annular frame 134 is connected with the adjusting block 135 in cooperation.

[0067] The support rod 136 corresponding to the adjusting block 135 is slidingly arranged on the circumferential surface of the clamping disc 41 along the axial direction.

[0068] One end of the adjusting block 135 away from the annular frame 134 is respectively provided with a first inclined surface and a second inclined surface matched with the clamping block 42 and the support rod 136. The clamping disc 41 is internally provided with an elastic expansion rod for resetting and supporting the support rod 136 and the clamping block 42. Since the elastic expansion rod is prior art, it will not be described in detail in the subsequent description, and it is not shown in the figure.

[0069] In specific work, when the waste battery 100 enters the internal material removal area through the terminal removal area, the waste battery 100 with the removed terminals is aligned with the clamping disc 41. The moving frame 132 is moved by external driving (electric sliding block, etc.), and the clamping disc 41 is moved into the battery shell by the moving frame 132. At this time, the carbon rod is inserted into the through circular groove, and then the annular frame 134 is moved to one side of the battery shell by external driving. The adjusting block 135 is moved into the battery shell by the annular frame 134. The first inclined surface of the adjusting block 135 contacts the clamping block 42 and pushes the clamping block 42 to move to one side of the carbon rod. At this time, the clamping block 42 clamps the carbon rod. The clamping block 42 no longer moves along the axial direction of the clamping disc 41. In the moving process of the adjusting block 135, the second inclined surface abuts against the support rod 136 and moves the support rod 136 to the inner wall of the battery shell. In the moving process of the support rod 136, the inner wall of the battery shell is supported, so that the vertical plate 3 restores the extruded part of the battery shell, thereby preparing for the subsequent removal of the electrolyte.

[0070] It should be noted that when the slope pair of clamping blocks 42 is adjusted, the adjusting block 135 continues to move to drive the slope pair of supporting rods 136 to adjust, that is, the adjusting stroke of the supporting rod 136 is greater than that of the clamping block 42, and the supporting rod 136 can also support and limit the battery shell to ensure the stability of the battery shell during the subsequent electrolyte removal process, avoiding the possibility of the battery shell shaking and falling.

[0071] Referring to Figure 5 And Figure 8 , the horizontal rack 133 is slidably provided with a U-shaped frame 137 facing the support frame 12 along the length direction of the horizontal rack 133 through the supporting protrusions, two vertical sections of the U-shaped frame 137 are rotatably provided with rotating rods 138 extending along the length direction of the horizontal rack 133, the two rotating rods 138 are drivingly connected through belt transmission, and a section of the rotating rod 138 away from the U-shaped frame 137 is provided with a spiral blade 139. The clamping disc 41 is also provided with a through groove 130 for accommodating the rotating rod 138.

[0072] The supporting rod 136 can support and restore the inner wall of the battery shell during movement to avoid collision between the rotating rod 138 and the battery shell during movement into the battery shell, and to avoid the possibility of blocking the electrolyte during subsequent electrolyte discharge.

[0073] In specific work, after the battery shell is supported and limited and the carbon rod is clamped, the U-shaped frame 137 is driven to move to the side of the battery shell by an external drive, the spiral blade 139 is driven to move into the battery shell by the rotating rod 138 during movement of the U-shaped frame 137, and the remaining rotating rod 138 is driven to rotate by the belt transmission during rotation of the rotating rod 138 driven by an external motor (not shown in the figure). During rotation of the rotating rod 138, the spiral blade 139 driven by the rotating rod 138 can loosen the electrolyte in the battery shell, so that the electrolyte in the battery shell can be loosened and discharged outward.

[0074] The through groove 130 can accommodate the rotating rod 138 to prevent the rotating rod 138 from colliding with the clamping disc 41 while being close to the carbon rod, so that the electrolyte around the carbon rod can be loosened when the spiral blade 139 driven by the rotating rod 138 loosens the electrolyte, reducing the friction between the carbon rod and the electrolyte, thereby facilitating the subsequent pulling of the carbon rod from the electrolyte by the clamping disc 41.

[0075] The horizontal frame 133 is arranged on the moving frame 132 along the width direction of the horizontal support 131, the moving frame 132 is composed of frame one and frame two which are in sliding cooperation with each other, the frame two is in sliding cooperation with the horizontal support 131, the frame one is in sliding cooperation with the moving frame 132, and during the process of excavating the electrolyte by the spiral blade 139, the frame one is slightly moved up and down by external force, the moving frame 132 is slightly moved along the width direction of the horizontal support 131, and then the clamping disc 41 is slightly shaken, and the excavated electrolyte is shaken to increase its inertia, and the separation effect between the electrolyte and the battery shell is improved.

[0076] In addition, during the process of excavating by the spiral blade 139, the annular frame 134 is moved a small distance away from the conveying belt 1, at this time, the adjusting block 135 is synchronously moved, the second inclined surface is moved a certain displacement during the movement of the adjusting block 135, at this time, the clamping block 42 is not in contact with the first inclined surface, the supporting rod 136 is driven to reset by the elastic expansion rod, so that the end of the supporting spring rod 127 away from the adjusting block 135 is separated from the battery shell, and then the frame one is slightly moved up and down by external force, the moving frame 132 is slightly moved along the width direction of the horizontal support 131, and then the clamping disc 41 is slightly shaken to drive the carbon rod to shake, the electrolyte around the carbon rod is extruded during the shaking process of the carbon rod, and then a conical aperture larger than the diameter of the carbon rod is formed in the electrolyte, that is, the electrolyte around the carbon rod can be relatively separated from the carbon rod, and then the carbon rod is conveniently pulled out.

[0077] When the end of the rotating rod 138 with the spiral blade 139 is moved to the negative terminal of the battery shell, it is reset, at this time, the electrolyte can be taken out, and the carbon rod is pulled out by the cooperation of the clamping disc 41 and the clamping block 42.

[0078] Referring to Figure 9 and Figure 10The rubber stick can limit the battery shell, specifically, the bottom of the support frame one 12 away from the drive gear is slidably provided with a vertical connecting frame 121 along the width direction thereof, the vertical connecting frame 121 is provided with a rubber plate 122 at an end thereof away from the corresponding support frame one 12, and the rubber plate 122 is provided with an inclined slope at an end thereof close to the conductive U-shaped rod 21, a vertical connecting plate 123 is installed at the bottom of the support frame one 12 away from the drive gear and close to the conveying belt 1, the vertical connecting plate 123 is provided with a driven gear 124 at an end thereof away from the corresponding support frame one 12 through a rotating connecting shaft, and a rack plate one 125 engaged with the driven gear 124 is slidably arranged on the vertical connecting plate 123, and the rack plate one 125 is abutted on the corresponding conveying belt 1 of the support frame one 12 at an end thereof away from the drive gear, and the rubber plate 122 is provided with a rack plate two 126 engaged with the driven gear 124.

[0079] In specific work, when the battery shell enters the internal substance removal area, it enters the bottom of the rubber plate 122 through the inclined slope, when the battery shell has a tendency to drive the conveying belt 1 to move, the conveying belt 1 gives an external force to the rack plate one 125 so that the rack plate one 125 has a tendency to move away from the conveying belt 1, the rack plate one 125 drives the driven gear 124 to have a tendency to rotate, the driven gear 124 has a tendency to rotate, which can drive the rack plate two 126 to have a tendency to move to the side of the conveying belt 1, and then the rack plate two 126 drives the battery shell to have a tendency to move to the side of the conveying belt 1 through the cooperation of the rubber plate 122 and the rolling rod 34, thereby reducing the possibility of the battery shell falling off the conveying belt 1.

[0080] Embodiment two: refer to Figure 9 and Figure 10 On the basis of embodiment one, the support frame one 12 away from the drive gear is provided with a fixed protrusion, the bottom of the fixed protrusion is provided with a support spring rod 127, and the support spring rod 127 is provided with a pressing rod 128 at an end thereof away from the fixed protrusion.

[0082] In addition, the lower pressing rod 128 can also knock the battery shell in the internal substance removing area, and the electrolyte in the battery shell is further separated from the battery shell by the cooperation of the shaking in the battery shell and the external knocking, and the pressing plate 129 and the connecting spring rods can cooperate to reduce the rigid impact of the lower pressing rod 128 and the battery shell in the internal substance removing area, so as to avoid that the impact displacement of the battery shell in the internal substance removing area is too large to affect the stability of the removal of the electrolyte in the battery shell in the internal substance removing area and the pulling out of the carbon rod.

[0083] Finally, with reference to Figure 11 The application also provides a dry method for breaking waste batteries without fire, and the process comprises the following steps: S1: placing and preparing, placing the waste batteries 100 between the two arc-shaped grooves 11 close to the driving gear of the conveying belt 1.

[0084] S2: conveying treatment, when the conveying belt 1 sends the waste battery 100 into the two vertical sections between the conductive type pole 21, at this time the positive and negative poles of the waste battery 100 are in contact with the corresponding electric contact 22, at this time the conductive type pole 21, the electric contact 22, the waste battery 100 and the alarm 23 form a closed loop, if the waste battery 100 is higher than the alarm 23 required for the alarm, at this time the alarm 23 alarms, at this time the telescopic cylinder 211 is started, the telescopic end of the telescopic cylinder 211 drives the push plate 215 to move to one side of the conveying belt 1, when the push plate 215 guide slope abuts against the linkage rod 213, at this time the linkage rod 213 moves up along the guide slope due to the blockage of the push plate 215 guide slope, the linkage rod 213 moves up in the vertical frame 212 and cooperates with the annular groove 214 to drive the conveying belt 1 to move slightly by a displacement, at this time the waste battery 100 corresponding to the conveying belt 1 part needs to be lifted up a certain distance, that is, the waste battery 100 corresponding to the circular channel needs to be opened outward, when the linkage rod 213 completely passes over the guide slope, the linkage rod 213 slides on the top of the push plate 215, the linkage rod 213 no longer has vertical displacement, at this time the telescopic end of the telescopic cylinder 211 is quickly retracted to one side of the conveying belt 1, the telescopic end of the telescopic cylinder 211 gives the waste battery 100 a momentary thrust through the push plate 215, so as to discharge the waste battery 100 with an electric quantity higher than the alarm electric quantity of the alarm 23 outward.

[0085] S3: terminal removal treatment, the waste battery 100 detected in the detection area and with an electric quantity lower than the alarm electric quantity of the alarm is conveyed into the terminal removal area by the conveying belt 1, the waste battery 100 moves to the position between the rolling rod 34 and the vertical plate 3 during conveying, the vertical plate 3 can exert an external force on the positive terminal of the waste battery 100 and the battery shell connection, so that the external force can extrude the battery shell to separate the battery shell from the positive terminal, so that the battery shell and the positive terminal are separated by the slight extrusion of the vertical plate 3, so that the internal structure of the waste battery 100 is exposed.

[0086] S4: waste removal, when the rotating rod 138 with the spiral blade 139 moves to the negative terminal of the battery shell, it is reset, at this time the electrolyte can be taken out, and the carbon rod can be pulled out by the cooperation of the clamping disc 41 and the clamping block 42.
