Description

Technical Field

[0001] This application relates to the technical field of crushing waste batteries, and particularly to an equipment and process for dry crushing waste batteries without catching fire. Background Art

[0002] Waste batteries refer to batteries that have lost their use value or cannot be recharged, including dry batteries and rechargeable batteries. Among them, dry batteries usually consist of a battery case with a circular structure. Inside the battery case, there is a carbon rod. Around the carbon rod inside the battery case, there is an electrolyte (such as manganese dioxide). Positive and negative terminals are respectively arranged at both ends of the battery case. The positive terminal is in contact connection with the carbon rod, and there is a certain gap between the electrolyte and the positive terminal. Waste batteries usually contain harmful metal elements or chemical substances. If not properly processed, they may cause damage to the environment and health. Therefore, it is very important to correctly recycle and process waste batteries to reduce environmental pollution and achieve effective reuse of resources.

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

[0004] For example, the patent application with the publication number CN219483737U discloses a waste battery crushing and separating recycling mechanism, including a separating and recycling box. The inner wall of the separating and recycling box is fixedly installed with a receiving and conveying box. A separating mechanism is arranged at the bottom end of the separating and recycling box, and a conveying mechanism is arranged inside the receiving and conveying box. This waste battery crushing and separating recycling mechanism achieves the effect of receiving the crushed shell by the receiving and conveying box after crushing the waste battery through the separating mechanism and the conveying mechanism. Under the conveying of the conveying rollers, the crushed shell is controlled to be conveyed. While conveying, while the separating rollers of the separating mechanism rotate and reciprocate, the pole powder of the crushed shell is scraped off, so as to enhance the separating effect, make the separation thorough, facilitate recycling, and have a high separation and recycling efficiency.

[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 waste batteries. In order to completely crush the waste batteries by external force, a relatively large pressure needs to be applied to the battery case of the waste battery. Therefore, the pressure on the battery case of the waste battery is relatively large, and the reaction of the electrolyte inside the waste battery under pressure intensifies, and the waste battery will catch fire and explode. Moreover, the above-mentioned prior art does not perform a power detection test on the waste battery during crushing. If the remaining power of the waste battery is relatively large, the possibility of short circuit of the internal circuit of the waste battery due to external force extrusion deformation during the crushing process of the waste battery is further increased, which further increases the degree of combustion and explosion of the waste battery and has a greater risk.

[0006] In addition, the above-mentioned existing technologies do not classify the various parts of waste batteries during crushing and separation, resulting in the mixing of various components of waste batteries after crushing and separation, which is not easy to classify and recycle. Moreover, various parts of waste batteries are severely damaged (such as the cutting of battery casings, carbon rods, and the scattering of electrolytes, etc.), affecting the crushing and separation effect of waste batteries.

[0007] Based on this, the above-mentioned patent application still needs to be improved in the way of crushing and separating waste batteries. Summary of the Invention

DETAILED DESCRIPTION

[0044] The following is combined with Figures 1 to 12 This application is described in further detail.

[0045] The embodiments of the present application disclose equipment and a process for dry crushing of used batteries without causing fire, which can gradually crush the used batteries by plugging them together, reduce the tediousness of re-sorting caused by the accumulation of crushed used battery parts, and reduce the possibility of combustion and explosion of used batteries during the crushing process.

[0046] Embodiment 1:

[0047] Reference Figure 1 A non-fire dry method of crushing waste batteries equipment comprises symmetrically arranged conveyor belts 1, each of which is provided with a plurality of evenly distributed arc grooves 11, and the arc grooves 11 on the two conveyor belts 1 correspond to each other one by one, and a detection area, a terminal removal area and an internal material removal area are sequentially arranged between the two conveyor belts 1 along their length direction.

[0048] The round grooves formed by the arc grooves 11 corresponding to the adjacent parts of the conveyor belt 1 can clamp the waste batteries 100, and the diameter of the round grooves is slightly smaller than the diameter of the waste batteries 100, so as to ensure that the conveyor belt 1 gives the waste batteries 100 a holding force when clamping and conveying the waste batteries 100, so as to prevent the waste batteries 100 from falling off the conveyor belt 1. The conveyor belt 1 is made of rubber material, so the contact area between the waste batteries 100 and the waste batteries 100 is larger, and the clamping is more stable. The arc grooves 11 are also provided with a giving way inclined surface to ensure that the waste batteries 100 can be guided when inserted into the round grooves, so that the waste batteries 100 can be smoothly inserted into the round grooves.

[0049] ReferenceFigure 1 On both sides of the top conveyor belt 1, support frames 12 are symmetrically arranged along the width direction of the conveyor belt 1, and on both sides of the bottom conveyor belt 1, support frames 13 are symmetrically arranged along the width direction of the conveyor belt 1. Pulleys 14 matching the corresponding conveyor belt 1 are installed between the two ends of the corresponding support frames of the same conveyor belt 1 through bearings, and any two adjacent pulleys 14 are connected through driving gears. A vertical rod 15 is installed on the support frames 12 and 13 close to the driving gear, and a limiting round rod 16 for limiting the position of the waste battery 100 is installed on the vertical rod 15.

[0050] The used batteries 100 are placed between the two arc grooves 11 of the conveyor belt 1 close to the driving gear, wherein the area closest to the driving gear is the loading area, that is, the used batteries 100 are clamped in the circular groove located in the loading area. When the used batteries 100 are clamped, any pulley 14 close to the driving gear is driven to rotate by the existing stepper motor. During the rotation of the pulley 14, the adjacent pulley 14 is driven to rotate by the driving gear. The two pulleys 14 cooperate with the remaining two pulleys 14 to drive the conveyor belt 1 intermittently. During the intermittent transmission of the conveyor belt 1, the used batteries 100 are driven into the detection area. At this time, there are no used batteries 100 in the circular groove corresponding to the loading area. The used batteries 100 are manually placed in the circular groove closest to the driving gear. The stepper motor can drive the used batteries 100 in the conveying process of the conveyor belt 1 to accurately enter the detection area, the terminal removal area and the internal material removal area.

[0051] The vertical rod 15 and the limiting round rod 16 cooperate with each other to limit the waste batteries 100 placed in the loading area, so that the two ends of the waste batteries 100 transported by the conveyor belt 1 are located on the same vertical plane, which is convenient for subsequent equipment parts to enter the waste batteries 100.

[0052] Reference Figure 1 as well as Figure 3 A detection mechanism 2 is arranged inside the detection area, including: a conductive 匚-shaped rod 21, which is arranged in the detection area, and electrical contacts 22 are installed at the ends of the two vertical sections of the conductive 匚-shaped rod 21.

[0053] The alarm 23 is arranged on the horizontal section of the conductive ⌚-shaped rod 21 and is connected in series to a closed circuit consisting of the conductive ⌚-shaped rod 21, the electrical contact 22 and the used battery 100.

[0054] The conductive U-shaped rod 21 is a metal rod and has conductivity. It should be noted that if the power of the waste battery 100 is lower than the power at which the alarm 23 sounds, it means that the waste battery 100 can enter the terminal removal area. Conversely, it cannot enter the terminal removal area and the waste battery 100 needs to be removed from the conveyor belt 1. In addition, it needs to be further explained that the power at which the alarm 23 sounds is very low. During specific operation, when the conveyor belt 1 sends the waste battery 100 between the two vertical segments of the conductive U-shaped rod 21, the positive and negative electrodes of the waste battery 100 are respectively in contact with the corresponding electrical contacts 22 at this time. At this time, the conductive U-shaped rod 21, the electrical contacts 22, the waste battery 100, and the alarm 23 form a closed circuit. If the power of the waste battery 100 is lower than a certain value, that is, the power of the waste battery 100 is lower than the power required for the alarm 23 to sound, the alarm 23 does not sound at this time, and the conveyor belt 1 continues to convey the waste battery 100 for the next step of processing.

[0055] Refer to Figure 3 , the horizontal section of the conductive U-shaped rod 21 is installed at the bottom of the first support frame 12 away from the driving gear. A telescopic cylinder 211 is installed on the second support frame 13 away from the driving gear through a cylinder seat, and the telescopic cylinder 211 is located between the U-shaped frame 137 and the vertical plate 3. A vertical frame 212 is installed at the bottom of the first support frame 12 away from the driving gear. A linkage rod 213 is slidably arranged along the length direction on the vertical frame 212. An annular groove 214 extending along the length of the conveyor belt 1 is provided on the side of the conveyor belt 1 corresponding to the first support frame 12 and away from the driving gear. One section of the linkage rod 213 close to the driving gear abuts against the inside of the annular groove 214. A push plate 215 is installed at the telescopic end of the telescopic cylinder 211. A guiding inclined surface cooperating with the linkage rod 213 is provided on the side of the push plate 215 close to the conveyor belt 1.

[0056] If the power of the waste battery 100 is higher than the power required for the alarm of the alarm 23, the alarm 23 will sound at this time, and the conveyor 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 activated. The telescopic end of the telescopic cylinder 211 drives the push plate 215 to move towards the conveyor belt 1. It should be noted that during the movement of the push plate 215, the guiding slope of the push plate 215 first contacts the linkage rod 213, and then the push plate 215 abuts against the waste battery 100. Specifically, when the guiding slope of the push plate 215 abuts against the linkage rod 213, the linkage rod 213 moves upward along the guiding slope due to the blocking of the guiding slope of the push plate 215. During the upward movement of the linkage rod 213 inside the vertical frame 212, it cooperates with the annular groove 214 to drive the conveyor belt 1 to move slightly by a certain displacement. At this time, the part of the conveyor belt 1 corresponding to the waste battery 100 that needs to be discharged outward is lifted upward by a certain distance, that is, the circular trough corresponding to the waste battery 100 that needs to be discharged outward is opened, thereby ensuring that when the waste battery 100 is discharged subsequently, it is impossible for the waste battery 100 to be unable to be discharged due to excessive clamping between the waste battery 100 and the conveyor belt 1.

[0057] When the linkage rod 213 completely crosses the guiding slope, the linkage rod 213 slides on the top of the push plate 215, and the linkage rod 213 no longer has a displacement in the vertical direction. At this time, the telescopic end of the telescopic cylinder 211 quickly contracts towards the conveyor belt 1. The telescopic end of the telescopic cylinder 211 gives the waste battery 100 an instantaneous thrust through the push plate 215, so that the waste battery 100 with a power higher than the alarm power of the alarm 23 can be discharged outward, thus avoiding the possibility of fire or even explosion during the subsequent operation in the terminal area due to the excessive internal power of the waste battery 100.

[0058] The discharged waste battery 100 can be collected and processed through an existing collection box.

[0059] Continue to refer to Figure 3 , a vertical plate 3 is provided in the terminal area. One end of the vertical plate 3 away from the detection area is provided with a guiding plate 31 inclined away from the conveyor belt 1.

[0060] On the support frame two 13 away from the driving gear, there are symmetrically arranged bearing brackets 32 along its length direction. The vertical plate 3 is installed on the two bearing brackets 32. At the bottom of the support frame one 12 away from the driving gear, there is a fixed connecting frame 33 that is matched with the vertical plate 3 and has an inverted T-shaped structure. The vertical section of the fixed connecting frame 33 is installed on the corresponding support frame one 12, and the bottom of the horizontal section of the fixed connecting frame 33 is provided with a plurality of rolling rods 34 along its length direction, and a guiding slope is provided on the side of the rolling rod 34 close to the conductive U-shaped rod 21.

[0061] The height of the top of the vertical plate 3 is slightly higher than the height of the bottom of the waste battery 100 entering the terminal removal area, and the height of the bottom of the rolling rod 34 is slightly lower than the height of the top of the waste battery 100 entering the terminal removal area. During specific operation, the waste battery 100 that has passed through the detection area and whose power is lower than the alarm power of the alarm is conveyed by the conveyor belt 1 and then enters the terminal removal area. During the conveyance of the waste battery 100, it moves between the rolling rod 34 and the vertical plate 3. The vertical plate 3 can apply an external force to the connection between the positive terminal of the waste battery 100 and the battery case (i.e., Figure 12 the arrow position), and then this external force can squeeze the battery case to separate the battery case from the positive terminal. Thus, through the slight extrusion of the vertical plate 3, the battery case is separated from the positive terminal, exposing the internal structure of the waste battery 100. Among them, the guiding inclined plane guides the waste battery 100 when the waste battery 100 enters between the rolling rod 34 and the vertical plate 3, facilitating the waste battery 100 to enter the bottom of the rolling rod 34.

[0062] As the conveyor belt 1 continues to drive the waste battery 100 to move, the vertical plate 3 can squeeze the circumference of the battery case. During the separation process of the battery case and the positive terminal, the rolling rod 34 can provide a fulcrum for the vertical plate 3 when squeezing the connection between the positive terminal and the battery case through the fixed connecting frame 33, and can also slightly squeeze and deform the battery case, applying an external force to the battery case to separate the battery case from the electrolyte, preventing the electrolyte of the waste battery 100 from adhering to the inside of the battery case and facilitating the subsequent removal of the electrolyte from the inside of the battery case.

[0063] When the waste battery 100 moves out of the vertical plate 3 and contacts the guiding plate 31, at this time, the positive terminal moves away from the conveyor belt 1 due to the blockage of the guiding plate 31. At this time, due to the blockage of the vertical plate 3, the battery case will not move away from the conveyor belt 1. Thus, at this time, the positive terminal is separated from the battery case.

[0064] Among them, when the positive terminal contacts the guiding plate 31, the indentation of the rolling rod 34 on the battery case can also cooperate with the rolling rod 34 to limit the position of the battery case, avoiding the possibility that the positive terminal drives the battery case to move synchronously when detaching from the battery case through the guiding plate 31.

[0065] Refer to Figure 1 and Figure 4 , a material taking mechanism 4 is arranged in the internal material removal area, including: a clamping disc 41, arranged in the internal material removal area, and a through circular groove for making way for the carbon rod is arranged at the center of the clamping disc 41.

[0066] Refer to Figure 5 , Figure 6 and Figure 7 , clamping blocks 42, a plurality of which are evenly arranged along the circumferential direction inside the clamping disc 41 for clamping and limiting the carbon rod.

[0067] A horizontal bracket 131 is installed on the second support frame 13 away from the driving gear. A moving frame 132 is slidably arranged on the horizontal bracket 131. One end of the moving frame 132 away from the horizontal bracket 131 is provided with a horizontal frame 133. And the clamping disc 41 is installed at one end of the horizontal frame 133 close to the conveyor belt 1. An annular frame 134 is slidably arranged on the horizontal frame 133 through a moving protrusion. A plurality of adjusting blocks 135 corresponding to the clamping blocks 42 one by one are slidably arranged through the end face of the clamping disc 41. And the annular frame 134 is cooperatively connected with the adjusting blocks 135.

[0068] Support rods 136 corresponding to the adjusting blocks 135 one by one are slidably arranged on the circumferential surface of the clamping disc 41 along its axis direction.

[0069] 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 which are cooperated with the clamping block 42 and the support rod 136. An elastic telescopic rod for resetting and supporting the support rod 136 and the clamping block 42 is arranged inside the clamping disc 41. Since the elastic telescopic rod is a prior art, it will not be described in detail in the subsequent description and is not shown in the figure.

[0070] During specific operation, when the waste battery 100 enters the internal substance removal area through the terminal removal area, at this time, the waste battery 100 with the terminal removed is aligned with the clamping disc 41. The moving frame 132 is driven to move through an external drive (such as an electric slider, etc.). During the movement of the moving frame 132, the clamping disc 41 is driven to move into the battery shell. At this time, the carbon rod is inserted into the through circular groove. Then, the annular frame 134 is pushed to move towards one side of the battery shell through an external drive. During the movement of the annular frame 134, the adjusting block 135 is pushed to move into the battery shell. During the movement of the adjusting block 135, the first inclined surface contacts the clamping block 42 and pushes the clamping block 42 to move towards the carbon rod side. At this time, the clamping block 42 can clamp the carbon rod. When the clamping block 42 separates from the first inclined surface and moves to one side wall of the adjusting block 135, at this time, the clamping block 42 just clamps the carbon rod, and the clamping block 42 no longer moves along the axis direction of the clamping disc 41. During the movement of the adjusting block 135, the second inclined surface simultaneously abuts against the support rod 136 and makes the support rod 136 move towards the inner wall of the battery shell. During the movement of the support rod 136, it can support the inner wall of the battery shell, so that the vertical plate 3 restores the extruded part of the battery shell, thereby preparing for the subsequent removal of the electrolyte.

[0071] It should be noted that after the adjustment of the inclined surface pair of clamping blocks 42 is completed, the adjustment block 135 continues to move to drive the inclined surface to adjust the support rod 136, that is, the adjustment stroke of the support rod 136 is greater than the adjustment stroke of the clamping block 42. At the same time, the support rod 136 can also support and limit the battery casing to ensure the stability of the battery casing during the subsequent electrolyte removal process and avoid the possibility of the battery casing shaking and falling.

[0072] Reference Figure 5 as well as Figure 8 A shaped frame 137 with an opening toward the support frame 12 is slidably provided on the horizontal frame 133 along its length direction through a supporting protrusion. A rotating rod 138 extending along the length direction of the horizontal frame 133 is rotatably installed on two vertical sections of the shaped frame 137. The two rotating rods 138 are connected by a belt drive. A spiral blade 139 is installed on a section of the rotating rod 138 away from the shaped frame 137. A through groove 130 is also provided on the clamping disc 41 to make way for the rotating rod 138.

[0073] During the movement of the support rod 136, the inner wall of the battery casing can be supported and restored to prevent the rotating rod 138 from colliding with the battery casing during the movement into the battery casing, and to avoid the possibility of blocking the subsequent discharge of the electrolyte.

[0074] During specific operation, when the battery shell support is limited and the carbon rod is clamped, the mold frame 137 is driven by an external drive to move to one side of the battery shell. During the movement of the mold frame 137, the spiral blade 139 is driven to move to the inside of the battery shell by the rotating rod 138. At this time, any rotating rod 138 is driven to rotate by an external motor (not shown in the figure). During the rotation of the rotating rod 138, the remaining rotating rods 138 are driven to rotate by belt transmission. During the rotation of the rotating rod 138, the rotating rod 138 continues to move toward the inside of the battery shell. At this time, the rotating rod 138 drives the spiral blade 139 to dig the electrolyte inside the battery shell, so that the electrolyte inside the battery shell can be loosened and discharged outward.

[0075] The through groove 130 can make way for the rotating rod 138 so that the rotating rod 138 will not collide with the clamping disk 41 and will be closer to the carbon rod. Then, when the rotating rod 138 drives the spiral blade 139 to dig the electrolyte, the electrolyte around the carbon rod can be loosened, thereby reducing the friction between the carbon rod and the electrolyte, thereby facilitating the subsequent removal of the carbon rod from the electrolyte by the clamping disk 41.

[0076] Among them, the horizontal frame 133 is slidably arranged on the moving frame 132 along the width direction of the horizontal bracket 131. The moving frame 132 is composed of a first frame and a second frame that are slidably matched with each other. The second frame is slidably matched with the horizontal bracket 131, and the first frame is slidably matched with the moving frame 132. During specific operation, when the spiral blade 139 digs the electrolyte, the first frame is driven to move slightly up and down by an external force, and the moving frame 132 moves slightly along the width direction of the horizontal bracket 131, thereby driving the clamping disc 41 to shake slightly. Then, the dug electrolyte can be shaken to increase its inertia and improve the detachment effect between the electrolyte and the battery housing.

[0077] In addition, during the digging process of the spiral blade 139, the annular frame 134 is moved a small distance away from the conveyor belt 1. At this time, the adjusting block 135 moves synchronously. During the movement of the adjusting block 135, the second inclined surface moves a certain displacement first. At this time, the clamping block 42 does not contact the first inclined surface, and the support rod 136 drives the reset through the elastic telescopic rod, so that the end of the support spring rod 127 away from the adjusting block 135 is separated from the battery housing. Then, the first frame is driven to move slightly up and down by an external force, and the moving frame 132 moves slightly along the width direction of the horizontal bracket 131, thereby driving the clamping disc 41 to shake slightly and driving the carbon rod to shake. During the shaking of the carbon rod, the electrolyte around it can be squeezed, and then a conical pore 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, which is convenient for pulling out the carbon rod subsequently.

[0078] When the end of the rotating rod 138 with the spiral blade 139 moves to the negative terminal of the battery housing, it is reset. At this time, the electrolyte can be taken out, and at the same time, the clamping disc 41 and the clamping block 42 cooperate with each other to pull out the carbon rod.

[0079] Refer to Figure 9 and Figure 10, during the processes of the spiral blade 139 digging the electrolyte and extracting the carbon rod, etc., there may be a tendency for the battery housing to move away from the conveyor belt 1. When the force corresponding to this tendency is greater than the frictional force between the battery housing and the conveyor belt 1, problems such as the battery housing falling off may occur. To avoid the above problems, the rubber rod provided by the present invention can limit the battery housing. Specifically, a vertical connecting frame 121 is slidably arranged along the width direction at the bottom of the first support frame 12 away from the driving gear. One end of the vertical connecting frame 121 away from the corresponding first support frame 12 is provided with a rubber plate 122, and an inclined slope is provided at one end of the rubber plate 122 close to the conductive U-shaped rod 21. A vertical connecting plate 123 is installed on the bottom of the first support frame 12 away from the driving gear and close to the conveyor belt 1. One end of the vertical connecting plate 123 away from the corresponding first support frame 12 is provided with a driven gear 124 through a rotating connecting shaft. A first rack plate 125 meshing with the driven gear 124 is slidably arranged on the vertical connecting plate 123, and one end of the first rack plate 125 away from the driving gear abuts against the conveyor belt 1 corresponding to the first support frame 12. A second rack plate 126 meshing with the driven gear 124 is installed on the rubber plate 122.

[0080] During specific operation, when the battery housing enters the internal material removal area, it enters the bottom of the rubber plate 122 through the inclined slope. When the battery housing has a tendency to drive the conveyor belt 1 to move, the conveyor belt 1 applies an external force to the first rack plate 125, causing the first rack plate 125 to have a tendency to move away from the conveyor belt 1. At this time, the first rack plate 125 drives the driven gear 124 to have a tendency to rotate. During the process of the driven gear 124 having a tendency to rotate, it can drive the second rack plate 126 to have a tendency to move towards the conveyor belt 1. Furthermore, the second rack plate 126 drives the battery housing to have a tendency to move towards the conveyor belt 1 through the cooperation between the rubber plate 122 and the indentation of the rolling rod 34, thereby offsetting the tendency for the battery housing to move away from the conveyor belt 1 during the processes of the spiral blade 139 digging the electrolyte and extracting the carbon rod, etc., and thus reducing the possibility of the battery housing falling off the conveyor belt 1.

[0081] Embodiment 2: Refer to Figure 9 and Figure 10 , on the basis of Embodiment 1, a fixed protrusion is installed on the first support frame 12 away from the driving gear, a support spring rod 127 is installed at the bottom of the fixed protrusion, and a pressing rod 128 is installed at one end of the support spring rod 127 away from the fixed protrusion.

[0082] One end of the pressing rod 128 close to the internal material removal area is provided with a Z-shaped mechanism, and connecting spring rods symmetrically distributed along its length are installed on the horizontal section above one end of the pressing rod 128 close to the internal material removal area. A pressing plate 129 is jointly installed at the lower ends of the connecting spring rods. During specific operation, the pressing rod 128 is driven to move downward by an external force. During the downward movement of the pressing rod 128, the battery case moved out of the internal material removal area can be knocked, so that the electrolyte inside the battery case is separated from the battery case and in a loose state. At the same time, the pressing rod 128 presses the battery case to tilt at a certain angle, so that the electrolyte inside the battery case is poured out.

[0083] In addition, the pressing rod 128 can also knock the battery case in the internal material removal area. By cooperating with the shaking inside the battery case and the external knocking, the electrolyte inside the battery case is further separated from the battery case. The cooperation between the pressing plate 129 and the connecting spring rods can reduce the rigid impact between the pressing rod 128 and the battery case in the internal material removal area, and avoid the excessive impact displacement of the battery case in the internal material removal area, which affects the removal of the electrolyte inside the battery case in the internal material removal area and the stability of the carbon rod extraction.

[0084] Finally, referring to Figure 11 , the present invention also provides a process for dry crushing of waste batteries without ignition, and the process includes the following steps: S1: Placement preparation, place the waste battery 100 between two arc-shaped grooves 11 of the conveyor belt 1 close to the driving gear.

[0085] S2: Conveyor handling. When the conveyor belt 1 feeds the waste battery 100 between the two vertical sections of the conductive U-shaped rod 21, the positive and negative electrodes of the waste battery 100 are respectively in contact with the corresponding electrical contacts 22 at this time. At this time, the conductive U-shaped rod 21, the electrical contacts 22, the waste battery 100 and the alarm 23 form a closed circuit. If the power of the waste battery 100 is higher than the power required for the alarm 23 to give an alarm, the alarm 23 will give an alarm at this time. Then the telescopic cylinder 211 is started. The telescopic end of the telescopic cylinder 211 drives the push plate 215 to move towards the conveyor belt 1 side. When the guiding slope of the push plate 215 abuts against the linkage rod 213, the linkage rod 213 moves upward along the guiding slope due to the blockage of the guiding slope of the push plate 215. During the upward movement of the linkage rod 213 inside the vertical frame 212, it cooperates with the annular groove 214 to drive the conveyor belt 1 to move slightly by a certain displacement. At this time, the part of the conveyor belt 1 corresponding to the waste battery 100 that needs to be discharged outward is lifted upward by a certain distance, that is, the circular trough corresponding to the waste battery 100 that needs to be discharged outward is opened. When the linkage rod 213 completely crosses the guiding slope, the linkage rod 213 slides on the top of the push plate 215, and the linkage rod 213 no longer has a displacement in the vertical direction. At this time, the telescopic end of the telescopic cylinder 211 quickly contracts towards the conveyor belt 1 side. The telescopic end of the telescopic cylinder 211 gives an instantaneous thrust to the waste battery 100 through the push plate 215, so as to discharge the waste battery 100 with a power higher than the alarm power of the alarm 23 outward.

[0086] S3: Terminal removal processing. The waste battery 100 that has passed through the detection area and has a power lower than the alarm power of the alarm enters the terminal removal area after being conveyed by the conveyor belt 1. During the conveying process of the waste battery 100, it moves between the rolling rod 34 and the vertical plate 3. The vertical plate 3 can apply an external force to the connection between the positive terminal of the waste battery 100 and the battery case. Then this external force can squeeze the battery case to separate the battery case from the positive terminal, so that the battery case and the positive terminal are separated by the slight extrusion of the vertical plate 3, and the internal structure of the waste battery 100 is exposed.

[0087] S4: Scrap removal. When the end of the rotating rod 138 with the spiral blade 139 moves to the negative terminal of the battery case and then resets, the electrolyte can be taken out at this time. At the same time, the clamping disc 41 and the clamping block 42 cooperate with each other to pull out the carbon rod.
