A liquid electrolyte recovery device

Abstract

This invention provides a liquid electrolyte recovery device, relating to the field of electrolyte recovery technology. It includes a support platform with concave plates fixedly installed on both the left and right sides of the top of the platform. An electric cylinder is fixedly installed on the top surface of the concave plates, and a pressure plate is provided at the concave end of the concave plates. When the power is activated, the side protective baffle, rear protective baffle, and front protective baffle must be closed sequentially to form a mandatory safety procedure. Through the coordinated operation of the front, side, and rear protective baffles with the concave plates, a comprehensive enclosure of the T-slot workbench can be formed. This facilitates effective protection against the spread of hazardous materials during the puncture of used batteries, preventing direct contact with hazardous materials by workers in the event of explosions, electrolyte splashes, or other emergencies. It solves the problem that current used battery puncture operations lack mandatory protective procedures and are prone to operation due to worker negligence in failing to close the protective structure before activation.

Description

Technical Field

[0001] This invention relates to the field of electrolyte recovery technology, and more particularly to a liquid electrolyte recovery device. Background Technology

[0002] As a core component of batteries, the safety of liquid electrolyte recycling and processing directly affects the operational safety of operators. During the puncture recycling of used batteries, the sudden increase in internal pressure and electrolyte reaction can easily lead to sudden situations such as explosions and electrolyte splashes. For operational safety, regulations require the use of protective structures to shield and seal the used batteries, preventing explosions and other emergencies that could lead to direct contact with hazardous materials by workers. However, there are currently no mandatory protective procedures, and workers may neglect to close the protective structure before initiating the puncture operation, posing a safety hazard.

[0003] The control panel used for puncture operations is often directly exposed in the operating area, making it impossible to coordinate with the puncture operation and achieve synchronized shielding. This means that during the critical stage of inserting or removing the puncture needle, staff may misoperate, causing the puncture needle to move. Since the internal pressure of the battery has not yet been released stably, the abnormal movement of the puncture needle can easily lead to secondary risks such as fire or explosion, posing a safety hazard. Furthermore, after puncturing a used battery, the internal electrolyte needs a certain settling time to evaporate and the pressure to be released. However, since the control panel is not shielded during this time, staff may inadvertently move the puncture needle before waiting for this settling period, causing a sudden release of residual pressure inside the battery, resulting in electrolyte splashing or battery casing rupture, posing a safety hazard. Summary of the Invention

[0004] This invention relates to a liquid electrolyte recovery device, which solves the problems of the lack of mandatory protective procedures during the current waste battery puncture operation, which can easily lead to dangers such as direct contact explosion and electrolyte splashing due to the negligence of the staff in starting the operation without closing the protective structure; the control panel of the puncture operation is directly exposed and cannot be synchronously shielded in conjunction with the operation, which can easily cause secondary risks due to misoperation at critical stages.

[0007] A blocking control switch is fixedly installed on the upper right side of the concave end of the concave plate. The blocking control switch is a tactile switch with the button facing to the left. A hemispherical rubber pressing block a is fixedly installed on the right end face of the pressure plate. When the pressure plate and the blocking control switch are aligned, the rubber pressing block a presses against the button of the blocking control switch, and the blocking control switch is in the pressed-on state.

[0008] The front end of the support platform is provided with an operating groove, and a control panel is embedded in the upper part of the operating groove.

[0024] When the front return spring is in its natural state, the front mating opening and the insertion hole are misaligned, and the left end of the front pressing rod protrudes from the left opening end of the front pressing insertion hole.

[0025] Furthermore, a rear moving obstruction cavity is provided inside the support platform adjacent to the rear of the front moving obstruction cavity. The rear moving obstruction cavity is also connected to the insertion hole. A rear pressing insertion hole penetrating the right end face of the support platform is provided on the right side of the inner end of the rear moving obstruction cavity.

[0026] A rear obstruction block is slidably installed inside the rear moving obstruction cavity, and the left end face of the rear obstruction block is fixedly connected to the left side face of the inner end of the rear moving obstruction cavity by a rear return spring.

[0027] A rear-side pressing rod is fixedly installed on the right end face of the rear obstruction block, and the rear-side pressing rod is slidably inserted into the rear-side pressing hole.

[0028] A rear-side fitting opening is provided on both the front and rear ends of the rear obstruction block;

[0029] When the right end face of the rear pressing rod is on the same vertical plane as the right end face of the support platform, the rear mating opening and the insertion hole are in the same axial state, and the rear return spring is in the compressed state at this time.

[0030] When the rear return spring is in its natural state, the rear mating opening and the insertion hole are misaligned, and the right end of the rear pressing rod protrudes from the right opening end of the rear pressing insertion hole.

[0033] When the buckle b engages with the buckle groove, the two side protective baffles are in contact with the left and right end faces of the support platform, respectively. At this time, the protruding parts of the front and rear pressing rods are pressed into the front and rear pressing holes by the side protective baffles, respectively.

[0034] Furthermore, a rear protective baffle is rotatably installed on the rear end face of the support platform, and a fastener c is installed on the rear protective baffle;

[0035] When the buckle c engages with the buckle slot, the rear protective baffle is in contact with the rear end face of the support platform. If the front and rear mating openings are coaxial with the insertion hole at this time, the rear end of the insertion post is pressed into the insertion hole, and the button end of the power switch does not protrude from the front opening end of the insertion hole.

If the rear protective baffle is in contact with the rear end face of the support platform at this time, forming a position limit on the rear end of the insertion post, then the rubber pressing block b will press against the button end of the power switch, triggering the power switch to start.

[0038] A transparent observation window is installed on both the front and rear ends of the front protective baffle.

[0039] This invention provides a liquid electrolyte recovery device, which has the following beneficial effects:

[0040] The power-on process of this invention requires the sequential closure of the side protective baffle, rear protective baffle, and front protective baffle to form a mandatory safety procedure. Through the coordinated operation of the front, side, and rear protective baffles and the concave plate, a complete enclosure of the T-slot workbench can be formed. This is beneficial for preventing the spread of hazardous materials and avoiding direct contact with hazardous materials by workers in case of emergencies such as explosions or electrolyte splashes during the puncture of waste batteries. This mandatory safety procedure also eliminates the violation of puncture operations without closing the protective structure, ensuring that every puncture operation is carried out under the premise of adequate safety protection, and completely avoiding safety hazards caused by human negligence.

[0041] When the puncture needle of this invention is used for puncture and removal operations, the blocking control switch and the rubber pressing block a work together to rotate the circular baffle, thereby forcibly blocking the control panel for a certain period of time. This prevents the operator from accessing and operating the control panel, thus achieving a certain period of forced stillness after the puncture needle is inserted into the used battery and after removal. This prevents the puncture needle from moving due to operator error. This setting ensures that the pressure generated inside the battery due to puncture is continuously and stably released, effectively avoiding secondary risks such as fire and explosion caused by the random movement of the puncture needle, and achieving safe operation.

If the rear protective baffle 8 is in contact with the rear end of the support platform 1 at this time, forming a position limit on the rear end of the insertion post 7, then the rubber pressing block b403 will press against the button end of the power switch 702, triggering the power switch 702 to start; a transparent observation window 401 is installed on both the front and rear ends of the front protective baffle 4.

[0070] Working principle:

[0071] After the waste batteries awaiting electrolyte recovery undergo pretreatment (such as safe discharge pretreatment operations), they can be placed on the T-shaped groove workbench 3, with their puncture points corresponding to the positions of the puncture needles 204, and then the waste batteries can be clamped and fixed by the clamps.

[0072] The power switch 702 needs to be pressed to turn on the power in order to control the subsequent puncture operation. The specific operation is as follows:

[0073] First, rotate and close the two side protective baffles 5, so that the buckle b501 and the buckle groove 201 are engaged and locked to limit and fix the closed state of the side protective baffles 5. At this time, the protruding parts of the front pressing rod 6 and the rear pressing rod 9 are pressed into the front pressing hole 107 and the rear pressing hole 109 respectively by the side protective baffles 5, so that the front mating opening 602 of the front obstruction block 601 and the rear mating opening 902 of the rear obstruction block 901 are both coaxial with the insertion hole 102, thereby releasing the limitation on the insertion post 7 moving forward along the insertion hole 102;

[0074] After the limit is released, the plug pin 7 can be pushed forward along the plug hole 102, and then the rear protective baffle 8 can be rotated and closed so that the buckle c801 and the buckle groove 201 are engaged. At this time, the rear protective baffle 8 limits the position of the rear end of the plug pin 7. Based on the limiting and blocking of the rear protective baffle 8, the plug pin 7 will not move backward along the plug hole 102.

[0075] After the position of the plug 7 is limited, rotate and close the front protective baffle 4 so that the buckle a402 engages with the buckle groove 201. At this time, the rubber pressing block b403 corresponds to the position of the plug hole 102 and presses against the button end of the power switch 702, thereby triggering the power switch 702 to start and realize the power connection.

[0076] The aforementioned power-on operation is mandatory, requiring the sequential closure of the side protective baffle 5, the rear protective baffle 8, and the front protective baffle 4. This ensures that the front protective baffle 4, the side protective baffle 5, the rear protective baffle 8, and the concave plate 2 completely enclose the T-slot workbench 3. This effectively shields the workbench from any unexpected situations, such as explosions, that may occur during subsequent punctures, thus protecting the safety of the workers. Furthermore, a transparent observation window 401 is installed on both the front and rear ends of the front protective baffle 4. This allows workers to observe the puncture status of the waste battery through the transparent observation window 401.

[0077] After the power is turned on, the staff can control the push rod end of the electric cylinder 202 to extend (the extension length has been preset) through the control panel 1012. At this time, the push rod end of the electric cylinder 202 pushes the pressure plate 203 to move downward until the puncture needle 204 punctures the puncture point of the waste battery.

[0078] As the pressure plate 203 moves downward, when it moves downward to the position corresponding to the blocking control switch 205, the rubber pressing block a206 contacts the button end of the blocking control switch 205, so that the blocking control switch 205 is in the pressed start state, which sends a feedback signal to the microcontroller 1014. The microcontroller 1014 controls the shaft end of the motor 1010 to rotate 180 degrees, and at the same time controls the timing module 1013 to start timing.

[0079] In the initial state of motor 1010, the cut surface 1011 of the circular baffle 103 fixedly installed on its shaft faces upward. At this time, the control panel 1012 is not within the area obstructed by the circular baffle 103. Therefore, when the shaft of motor 1010 rotates 180 degrees, the circular baffle 103, which rotates with the shaft of motor 1010, rotates 180 degrees synchronously. At this time, the cut surface 1011 of the circular baffle 103 faces downward, and the circular baffle 103 completely obstructs the control panel 1012, preventing the operator from accessing and operating the control panel 1012. This is because the timing value of the timing module 1013... The time is five minutes (but not limited to this time value, and can be changed). Therefore, within five minutes, the operator cannot control the extension or retraction of the push rod end of the electric cylinder 202 through the control panel 1012. Based on this barrier setting, after the waste battery is punctured, it is kept in a static state for nearly five minutes with the puncture needle 204 inserted. This allows the pressure (gas, electrolyte tension) generated inside the battery due to puncture to be continuously and steadily released through the gap between the puncture needle 204 and the puncture channel. This avoids sudden situations such as fire or explosion of the waste battery due to movement of the puncture needle 204, ensuring safe operation.

[0080] When the timing value of the timing module 1013 is reached, the timing module 1013 sends a feedback signal to the microcontroller 1014. The microcontroller 1014 controls the shaft end of the motor 1010 to rotate 180 degrees. At this time, the circular baffle 103, which rotates with the shaft end of the motor 1010, rotates 180 degrees synchronously. The cut surface 1011 of the circular baffle 103 will face upward, and the circular baffle 103 will no longer block the control panel 1012, so that the operator can control the push rod end of the electric cylinder 202 to retract through the control panel 1012 to realize the needle removal operation.

[0081] When the pressure plate 203, which moves upward synchronously with the push rod end of the electric cylinder 202, moves again to the position corresponding to the isolation control switch 205, the microcontroller 1014 will control the shaft end of the motor 1010 to rotate 180 degrees again, based on the pressing start of the isolation control switch 205 by the rubber pressure block a206, and simultaneously control the timing module 1013 to start timing. At this time, the circular baffle 103 will block the control panel 1012 again to prevent the puncture needle 204 from contacting the waste battery again due to the operator's accidental operation of the control panel 1012. Through this five-minute isolation setting, after the needle is removed, the residual pressure is ensured to be released, achieving "pressure release end". During this period, the state of the waste battery after puncture and needle removal (whether there is continuous bubbling (abnormal gas release), large amount of electrolyte leakage, etc.) can be observed to confirm that there are no potential risks.

[0082] When the timing value of the timing module 1013 is reached again, the timing module 1013 sends a feedback signal to the microcontroller 1014.
