Description

Technical Field

[0001] The utility model relates to the technical field of waste battery recycling, in particular to a waste power battery recycling device. Background Art

[0002] End-of-life power battery recycling facilities are used to process retired lithium-ion batteries from new energy vehicles and electric devices. These facilities utilize physical, chemical, or biological methods to recycle useful materials from used batteries and safely dispose of hazardous substances. They play a vital role in the new energy vehicle industry. With the rapid growth of the electric vehicle market, a large number of power batteries are reaching end-of-life, necessitating effective recycling and treatment methods to reduce environmental pollution and resource waste. These facilities play a vital role in multiple sectors, including new energy, environmental protection, and resource recovery.

[0003] In the existing technology, during the recycling of scrapped power batteries, the first step is usually to physically crush the batteries. For certain types of batteries, especially lithium batteries, since there is still residual electrical energy inside the lithium batteries, thermal runaway is prone to occur during the crushing process, leading to battery explosion. This explosion not only generates high temperatures, but also causes battery fragments to splash, causing harm to nearby workers. In addition, the toxic and harmful gases released when the lithium battery explodes will also pose a threat to the health of the workers. At present, many power battery crushing equipment adopts a sloped transmission component design. Due to the difficulty in configuring an effective sealing door in the slope direction, this increases the risk of leakage of harmful substances and also makes maintenance inside the equipment difficult. If the sealing door is designed to open to the inside of the crushing equipment, although the sealing effect can be improved, in an emergency or when internal maintenance is required, it will be difficult for workers to quickly enter the equipment, which not only affects the operating efficiency of the equipment, but also leads to increased maintenance costs. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a power battery scrap recycling device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a power battery scrap recycling device, comprising a feeding ramp, wherein a crusher is fixed at one end of the feeding ramp, a shaft torque part is fixed at the top of the feeding ramp, a hinge torque part is fixed at the top of the feeding ramp, a fixed torque L part is fixed on the side of the shaft torque part, one end of the fixed torque L part is fixed to an end rod ring, the inner wall of the end rod ring is provided with a thin shaft, one end of the thin shaft is fixed with a limiting coarse shaft, the circumference of the limiting coarse shaft is fixed with an L gate arm, one end of the L gate arm is fixed with a splash gate, the circumference of the bottom end of the limiting coarse shaft is fixed with an outer peripheral L arm, one end of the peripheral L arm is fixed with a fine rotating rod, the circumference of the fine rotating rod is rotatably connected to the inner wheel of the groove, the bottom of the end rod ring is fixed with a bottom empty disc, the top of the bottom empty disc is fixed with a residual arc plate, the surface of the residual arc plate is provided with a cam arc groove, and the inner wall of the cam arc groove is slidably connected to the circumference of the inner wheel of the groove.

[0006] Preferably, a door end column is fixed to one end of the splash-proof door, a rectangular side bolt groove is opened on one side of the hinge member, the inner wall of the rectangular side bolt groove is rotatably connected to the inner wall rotary shaft, a return clamp spring is provided on the circumference of the inner wall rotary shaft, one end of the return clamp spring is fixed to the inner wall of the rectangular side bolt groove, a bolt limiter is fixed on the circumference of the inner wall rotary shaft, and an arc extension pick is fixed on one end of the bolt limiter. In the prior art, during the physical crushing process of the power battery, if the residual electrical energy inside the battery causes thermal runaway, it will cause the battery to explode. This explosion will generate huge impact force and high temperature, causing the battery fragments to splash at an extremely high speed. These splashing fragments and components have extremely high kinetic energy, and they will violently collide with the splash-proof door provided on the equipment. Due to the excessive impact force, the splash-proof door will lose its original protective function and be opened outward or even destroyed. Once the splash-proof door is opened, harmful substances and fragments that should have been confined inside the equipment will be released. It will escape into the working environment, which not only increases the safety risk in the workplace, but also leads to production accidents. Workers will be directly hit by flying debris or inhale toxic gases, causing physical harm. In addition, the damage to the equipment requires additional time and resources to repair and clean, which will affect production efficiency and increase production costs. To solve this problem, the utility model adopts an embedded bolt limiter to achieve a solution, so that when the worker closes the splash-proof door, the door end column enters the rectangular bolt groove, the surface of the door end column contacts the inclined surface at the bottom of the embedded bolt limiter, and the embedded bolt limiter is lifted counterclockwise with the inner wall rotation axis as the axis. When the door end column passes, the reset spring releases the elastic potential energy and rebounds, and the arc groove at the bottom of the embedded bolt limiter buckles the door end column, so that the splash-proof door is locked. When the worker needs to open the splash-proof door, the arc extension dial is lifted upward counterclockwise to disengage the door end column, thereby improving user experience and improving production safety.

[0007] Preferably, a spring insert is fixed to the inner wall of the cam arc groove, and a wheel axle arc insert is provided in a circumferential array on the circumferential surface of the wheel in the groove, and the inner wall of the wheel axle arc insert is nested with the surface of the spring insert. In the prior art, in the crushing equipment of the power battery, the wheel in the groove is one of the key transmission components, which is responsible for driving the opening and closing of the splash-proof door. When the wheel in the groove moves along the cam arc groove, it controls the position and state of the splash-proof door according to a preset trajectory. However, in actual operation, when the wheel in the groove reaches the two ends of the cam arc groove, it is difficult to stop the wheel in the groove immediately due to inertia and mechanical structure limitations. This difficult-to-control stop will cause the positioning of the splash-proof door to be affected. Inaccuracy makes it impossible for the door to stay accurately in the predetermined open or closed position. If the splash-proof door cannot maintain a stable position after opening, it will not be able to effectively perform its protective function, thereby increasing safety risks in the workplace. In addition, the unstable door position also causes harmful substances and debris inside the equipment to escape into the external environment, posing a threat to the health of workers. To address such problems, the present invention adopts the method of installing spring inserts to solve them. When the inner wheel reaches the two ends of the cam arc groove, the inner wall of the wheel axle arc groove on the circumference of the inner wheel is nested with the surface of the spring insert, thereby ensuring the stable position of the splash-proof door and achieving the effect of improving user experience.

[0008] Preferably, limiting arc disks are fixed to both ends of the thin rotating rod, thereby limiting the movement trajectory of the component and achieving the effect of improving the stability of the equipment.

[0009] Preferably, a shaft end limiting plate is fixed to one end of the thin shaft, thereby limiting the movement distance of the component and achieving the effect of improving the stability of the equipment.

[0010] Preferably, buffer ring pads are fixed at both ends of the limiting thick shaft to prevent collisions between components and achieve the effect of increasing the service life of the equipment.

[0011] Preferably, the surface of the arc extending selector is provided with anti-slip grooves, thereby increasing friction and improving user experience.

[0012] Beneficial effects:

[0013] 1. In the prior art, during the recycling of scrapped power batteries, the first step is usually to physically crush the batteries. For certain types of batteries, especially lithium batteries, since there is still residual electrical energy inside the lithium batteries, thermal runaway is prone to occur during the crushing process, leading to battery explosions. This explosion not only generates high temperatures, but also causes battery fragments to splash, causing harm to nearby workers. In addition, the toxic and harmful gases released when the lithium battery explodes will also pose a threat to the health of the workers. At present, many power battery crushing equipment adopts a sloped transmission component design. Due to the slope direction, it is difficult to configure an effective sealing door, which increases the risk of leakage of harmful substances and makes maintenance inside the equipment difficult. If the sealing door is designed to open to the inside of the crushing equipment, although the sealing effect can be improved, it is difficult to use in an emergency or when it is necessary to When performing internal maintenance, it will be difficult for staff to quickly enter the equipment, which not only affects the operating efficiency of the equipment, but also leads to an increase in maintenance costs. To address this problem, the utility model solves it by installing a residual arc plate, so that when the staff unloads materials into the crusher through the feed slope, the splash-proof door is pulled toward one side of the slope. The splash-proof door is pulled through the L-door arm to limit the thick shaft and the thin shaft from rotating in the inner wall of the end rod ring as the axis, and at the same time, the outer L-arm at the bottom end of the thick shaft is limited to rotate. Due to the coordination of the inner wheel of the groove and the cam arc groove, the splash-proof door is gradually raised by the restriction of the residual arc plate, and the thin shaft rises while rotating on the inner wall of the end rod ring, so that the splash-proof door rises while opening, thereby adapting to the slope. While being able to open to the inclined surface, the relevant components of the shaft are placed outside the crusher, thereby facilitating detection and maintenance, thereby improving user experience.

[0014] 2. In the prior art, during the physical crushing process of power batteries, if the residual electrical energy inside the battery triggers thermal runaway, it will cause the battery to explode. This explosion will generate huge impact force and high temperature, causing battery fragments to splash at a very high speed. These splashing fragments and components have extremely high kinetic energy, and they will violently collide with the splash-proof door provided on the equipment. Due to the excessive impact force, the splash-proof door will lose its original protective function and be opened outward or even damaged. Once the splash-proof door is opened, harmful substances and fragments that should have been confined inside the equipment will escape into the working environment, which not only increases the safety risk in the workplace, but also leads to the occurrence of production accidents. Workers will be directly hit by the splashing fragments, or Inhalation of toxic gases can cause physical harm. In addition, damage to the equipment requires additional time and resources to repair and clean, which will affect production efficiency and increase production costs. To address this problem, the utility model solves it by adopting an embedded bolt limiter. When the staff closes the splash-proof door, the door end column enters the rectangular bolt groove, and the surface of the door end column contacts the inclined surface at the bottom of the embedded bolt limiter, and the embedded bolt limiter is lifted counterclockwise with the inner wall rotation axis as the axis. When the door end column passes, the reset spring releases the elastic potential energy and rebounds. The arc groove at the bottom of the embedded bolt limiter buckles the door end column, locking the splash-proof door. When the staff needs to open the splash-proof door, the arc extension dial is lifted counterclockwise to disengage the door end column, thereby improving user experience and production safety.

[0015] 3. In the prior art, in the crushing equipment of power batteries, the inner wheel of the groove is one of the key transmission components, which is responsible for driving the opening and closing of the splash door. When the inner wheel of the groove moves along the cam arc groove, it controls the position and state of the splash door according to the preset trajectory. However, in actual operation, when the inner wheel of the groove reaches the two ends of the cam arc groove, due to inertia and mechanical structure limitations, it is difficult for the inner wheel of the groove to stop immediately. This difficult-to-control stop will lead to inaccurate positioning of the splash door, making it impossible for the door to accurately stay in the predetermined open or closed position. If the splash door cannot maintain a stable position after opening, it will not be able to effectively perform its protective function, thereby increasing safety risks in the workplace. In addition, the unstable door position also causes harmful substances and fragments inside the equipment to escape into the external environment, posing a threat to the health of workers. To address this problem, the utility model adopts the method of installing a spring insert to solve it. When the inner wheel reaches the two ends of the cam arc groove, the inner wall of the wheel axle arc insert on the circumference of the inner wheel is nested with the surface of the spring insert, thereby ensuring the stable position of the splash door and achieving the effect of improving user experience.

Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0025] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:

A thin rotating rod 2012 is fixed to one end of the outer L-arm 2011. The circumference of the thin rotating rod 2012 is rotatably connected to the inner wheel 2013 in the groove. A bottom empty disc 208 is fixed to the bottom of the end rod ring 203, and a residual arc plate 209 is fixed to the top of the bottom empty disc 208. A cam arc groove 2010 is provided on the surface of the residual arc plate 209, and the inner wall of the cam arc groove 2010 is slidably connected to the circumference of the inner wheel 2013 in the groove. One end of the splash-proof door 207 is fixed with a door end column 3, and one side of the hinge member 201 is provided with a rectangular side bolt groove 301. The inner wall of the rectangular side bolt groove 301 is rotatably connected to the inner wall rotating shaft 302. The circumference of the inner wall rotating shaft 302 is provided with a reset spring 303. One end of the reset spring 303 is fixed to the inner wall of the rectangular side bolt groove 301. The circumference of the inner wall rotating shaft 302 is fixed with an embedded bolt limiter 304. One end of the embedded bolt limiter 304 is fixed with an arc extending pick 305. During the physical crushing process of the power battery, if there is residual material inside the battery, The electrical energy will trigger thermal runaway, which will cause the battery to explode. This explosion will generate huge impact force and high temperature, causing battery fragments to splash at a very high speed. These flying fragments and components have extremely high kinetic energy, and they will violently hit the splash-proof door 207 set on the device. Due to the excessive impact force, the splash-proof door 207 will lose its original protective function and be opened outward or even destroyed. Once the splash-proof door 207 is opened, harmful substances and fragments that should have been confined inside the device will be released. When the worker needs to open the splash-proof door 207, the arc groove 305 is lifted upward counterclockwise to disengage the door end column 3, thereby improving user experience and improving production safety.

[0028] A spring insert 4 is fixed to the inner wall of the cam arc groove 2010, and an axle arc insert 401 is provided in a circumferential array on the circumference of the inner wheel 2013. The inner wall of the axle arc insert 401 is nested with the surface of the spring insert 4. In the crushing equipment of the power battery, the inner wheel 2013 is one of the key transmission components, which is responsible for driving the opening and closing of the splash-proof door 207. When the inner wheel 2013 moves along the cam arc groove 2010, it controls the position and state of the splash-proof door 207 according to a preset trajectory. However, in actual operation, when the inner wheel 2013 reaches the two ends of the cam arc groove 2010, it is difficult for the inner wheel 2013 to stop immediately due to inertia and mechanical structure limitations. This uncontrollable stop will lead to This results in inaccurate positioning of the splash door 207, preventing it from precisely remaining in the intended open or closed position. If the splash door 207 cannot maintain a stable position after opening, it will not be able to effectively perform its protective function, thereby increasing workplace safety risks. Furthermore, the unstable door position can cause harmful substances and debris inside the equipment to escape into the external environment, posing a health threat to workers. This problem is addressed by installing a spring insert 4. When the inner wheel 2013 reaches both ends of the cam arc groove 2010, the inner wall of the wheel arc groove 401 on the inner wheel 2013's surface interlocks with the surface of the spring insert 4, thereby ensuring the stable position of the splash door 207 and improving the user experience. A limiting arc disk 5 is fixed at each end of the thin rotating rod 2012, limiting the movement trajectory of the component and improving the stability of the equipment. A shaft end limiting disk 6 is fixed at one end of the thin shaft 204, limiting the movement distance of the component and improving the stability of the equipment. A buffer ring pad 601 is fixed at each end of the thick limiting shaft 205, preventing collisions between components and increasing the service life of the equipment. The arc extending selector 305 has anti-slip grooves on its surface, which increases friction and improves user experience.

[0029] The working principle of the utility model is as follows: when the staff unloads materials into the crusher 101 through the feeding ramp 1, the splash-proof door 207 is pulled toward one side of the ramp. The pulling of the splash-proof door 207 is carried out through the L-door arm 206 to limit the thick shaft 205 and the thin shaft 204 from rotating in the inner wall of the end rod ring 203. At the same time, when the outer peripheral L arm 2011 at the bottom end of the thick shaft 205 is limited to rotate, due to the matching of the inner wheel 2013 of the groove and the cam arc groove 2010, the splash-proof door 207 is gradually raised by the restriction of the residual arc plate 209. At the same time, the thin shaft 204 rises while rotating on the inner wall of the end rod ring 203, so that the splash-proof door 207 rises while opening, thereby adapting to the inclined surface. Slope, while being able to open to the inclined surface, the relevant components of the shaft are placed outside the crusher 101, so as to facilitate inspection and maintenance. When the staff closes the splash-proof door 207, the door end column 3 enters the moment side bolt groove 301, and the surface of the door end column 3 contacts the inclined surface at the bottom of the embedded bolt limiter 304, and the embedded bolt limiter 304 is lifted counterclockwise with the inner wall rotation axis 302 as the axis. When the door end column 3 passes, the reset spring 303 releases the elastic potential energy and rebounds, and the arc groove at the bottom of the embedded bolt limiter 304 buckles the door end column 3, so that the splash-proof door 207 is locked. When the staff needs to open the splash-proof door 207, the arc extension pick 305 is lifted counterclockwise to disengage the door end column 3.
