[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figures 1 to 6 As shown, a lead-acid battery recycling and processing device is disclosed in a specific embodiment of the present invention, including a cleaning tank 100, a stirring device 200, and a flushing device 300; a plurality of arranged water tanks 110 are provided on the cleaning tank 100, and an overflow port 120 is provided at the top of the water tank 110 close to the upstream side, and a drain pipe 130 is connected to the bottom of the overflow port 120; the stirring device 200 includes a plurality of stirring structures, which are installed in the corresponding water tanks, and the rotating stirring structures are used to bring up the materials in the water tanks and send them to the next water tank; the flushing device 300 includes a plurality of spray pipes, which are installed above the corresponding water tanks and are used to perform high-pressure water spraying on the materials passing below; a first water receiving tray 410 and a second water receiving tray 420 are provided below the cleaning tank 100, and the first water receiving tray is used to receive the overflow liquid of at least two water tanks at the end for flushing the upstream part; the second water receiving tray is used to receive the overflow liquid of the remaining water tanks; the liquid at the first water receiving tray is pumped through the flushing device and sprayed to the water tank corresponding to the second water receiving tray.

[0039] The above-mentioned lead-acid battery recycling and processing equipment adopts graded processing. The upstream link performs multiple stirring and flushing, and uses the flushing water in the downstream link as auxiliary water to reduce waste; the downstream link uses clean water as flushing water, and combined with the stirring action, it can effectively improve the cleaning of material fragments and reduce the waste of recyclable materials; and the design and layout of the overall structure can enable the material to be effectively moved progressively, so that the material fragments can be fully cleaned, and continuous processing and production can be achieved to improve efficiency.

[0040] Furthermore, if Figure 2 , Figure 3As shown, the stirring device 200 includes a first stirring structure 210 and a second stirring structure 220 driven by a first motor 230; the first stirring structure 210 and the second stirring structure 220 are rotatably installed in the water tank 110, and the first stirring structure and the second stirring structure are spaced apart from each other; Figure 8 , Fig. 9 As shown, the first stirring structure 210 includes a first shaft body 211, and a plurality of first material-moving members 212 are fixedly disposed on the outer wall of the first shaft body 211. The first material-moving members are distributed in a circular array around the axis of the first shaft body;

[0041] The first material-moving member 212 includes a first scraper 2121. A first baffle 2122 is fixedly provided at the end of the first scraper 2121 away from the first shaft 211. The outer wall of the first baffle 2122 is an arc-shaped structure and slides against the inner wall of the water tank 110. The first scraper 2121 is provided with a plurality of first strip holes 2123 extending in the radial direction.

[0042] like Fig.10 , Fig.11 As shown, the second stirring structure 220 includes a second shaft body 221, and a plurality of second material-shifting members 222 are fixedly provided on the outer wall of the second shaft body 221. The number of the second material-shifting members 222 is 1 / 2 of the first material-shifting members 212, and the second material-shifting members are distributed in a circular array around the axis of the second shaft body; the structure of the second material-shifting members 222 is the same as that of the first material-shifting members 212;

[0043] Among them, the first shaft and the second shaft are rotatably mounted on the two ends of the corresponding water tank through bearings, and the ends of the shafts extend out of the outside of the cleaning tank. The output shaft of the first motor is connected to the ends of the first shaft and the second shaft through a sprocket chain assembly to achieve rotation driven by the same first motor to ensure the consistency of rotation speed and angle, so as to carry out corresponding layout and ensure that the material can be driven to move downstream along the water tank; due to the different numbers of the first material shifting parts and the second material shifting parts, there will inevitably be partial overlap and partial misalignment. When there is partial overlap, the material will be blocked to a certain extent, causing part of the material to remain in the original water tank, which means that the material residence time can be extended for effective soaking and stirring cleaning; the partial misalignment design can ensure that the material can be smoothly transferred to the next water tank to achieve progressive movement of the material.

[0044] Furthermore, the flushing device includes a pump body, a plurality of first spray pipes, at least one second spray pipe and a plurality of third spray pipes, and a plurality of array-distributed high-pressure nozzles are installed at the bottom of each spray pipe; a plurality of first spray pipes are arranged above the water tank at the end above the first water receiving tray, and are arranged in an arc-shaped array and arranged at intervals corresponding to the first material-dispensing member on the water tank; a second spray pipe is arranged above the middle of each of the remaining water tanks above the first water receiving tray; a third spray pipe is arranged above the middle of the remaining water tanks; the first spray pipe and the second spray pipe The first confluence pipes converge to the first confluence pipe, which is used to connect to an external high-pressure water source; the third spray pipes are all connected and converged to the second confluence pipe, which is connected to the output port of the pump body through the first pipe, and the first solenoid valve is installed on the first pipe, and the input port of the pump body is connected to the first water receiving pan through the second pipe; the first confluence pipe is connected to the first pipe through the third pipe, and the connection point is located between the first solenoid valve and the second confluence pipe, and the second solenoid valve is installed on the third pipe; a liquid level gauge is installed in the first water receiving pan, and the water in the first water receiving pan is monitored by the liquid level gauge When the water volume is within the preset range, the first solenoid valve is opened, the second solenoid valve is closed, and the liquid in the first water receiving tray is pumped by the pump body as the liquid for spraying and flushing, thereby reducing the use of external water volume; when the water volume in the first water receiving tray drops to the range value, the first solenoid valve and the pump body are closed, the second solenoid valve is opened, and the high-pressure solution supplied from the outside is used for spraying and flushing; the above-mentioned structural design and layout are used to flush the materials with clean water at at least two water tanks at the end position to clean the end position; and, at the last water tank position, multiple first spray pipes are used for multi-point flushing, which effectively improves the flushing and cleaning quality and minimizes the discharge of material fragments mixed with sewage; the flushing water overflowed from the water tank corresponding to the first spray pipe and the second spray pipe is relatively clean, and is pumped and pressurized by the pump body to flush the materials at the upstream position and replenish water, thereby reducing waste; when the water volume in the first water receiving tray is insufficient, or in the replenishment action after the sewage is emptied, it is necessary to replenish the flushing water through an external water source, and the corresponding program is naturally started to conduct the corresponding pipeline;

[0045] It should be pointed out that an external discharge pipe is connected to the bottom of one end surface of each water tank, and a third solenoid valve is installed on the external discharge pipe for discharging internal sediment, impurities or liquid; the bottom of the side wall of the second water receiving tray is also connected to a discharge pipe for transferring to the next processing link.

[0046] Furthermore, if Figures 8 to 11As shown, at least two guide strips 2124 are fixedly provided on the wall surface facing the rotating and swinging of the first scraper 2121, and a push plate 213 is slidably clamped at the guide strips 2124, and the push plate slides along the guide strips as the first stirring structure rotates; the push plate will make corresponding position changes when the first stirring structure rotates and swings to different angles, especially when it rotates to a position close to the next water tank, the push plate moves downward to accelerate the downward movement of the pushed material fragments; wherein, a limiting bolt is installed on the top surface of the end of the guide strip away from the shaft body to prevent the push plate from completely detaching from the guide strip.

[0047] Furthermore, if Fig.12 As shown, a plurality of protrusions 2131 are fixedly provided on the bottom surface of the push plate 213, and the positions of the protrusions 2131 correspond to the positions of the first strip holes 2123. The protrusions 2131 are slidably arranged at the first strip holes 2123 for cleaning the first strip holes. The gravity of the push plate can be utilized to push and apply force to the material stuck at the first strip holes, which can achieve a clearing effect to a certain extent. Furthermore, both ends of the protrusions are blade-like structures, which can reduce the friction resistance between the protrusions and the first strip holes, and can also better push the material stuck at the first strip holes, thereby accelerating the loosening of the material.

[0048] Furthermore, if Figure 5 , Figure 7 As shown, the top side wall on the upstream side of the water tank 110 is provided with a groove 140, and the groove extends along the length direction of the water tank; the overflow port 120 is provided at the groove 140; the groove is used as the first overflow part to play a buffering effect, so as to better guide the overflow liquid to flow to the overflow port.

[0049] Furthermore, a retaining ring 150 is fixedly provided on the outer side of the top of the overflow port 120, and a filter screen 160 is installed on the top surface of the retaining ring 150; the elevated retaining ring can limit the specific location of the overflow water, and the liquid entering the groove needs to rise to above the filter screen before entering the overflow port, further limiting the overflow discharge speed and position, and filtering through the filter screen to reduce the discharge of debris particles.

[0050] Furthermore, the top surface of the retaining ring 150 is in a concave arc-shaped structure so as to achieve a collecting effect and facilitate drainage; the shape of the filter 160 is adapted to the shape of the top surface of the retaining ring 150, and the filter is tightly arranged on the top surface of the retaining ring for effective filtration; wherein, the two ends of the filter are fixed with downwardly folded flanges, which are tightly attached to the outer walls of the two ends of the retaining ring and are fixedly connected by bolts, adopting a disassemblyable structure, which is convenient for the processing and production of parts and components, and the assembly is also relatively simple.

[0051] Furthermore, if Figure 3 , Figure 4As shown, a pushing structure 500 is installed at the groove 140, and multiple pushing structures 500 are all connected to the second motor 600. The second motor 600 drives the pushing structure 500 to extend and retract from the groove notch and along the radial direction of the water tank; it is used to drive the movement of the first baffle at the corresponding position; the pushing structure is hidden in the groove and does not affect the rotation and swing of the stirring structure; it can be extended and retracted, and can coordinate with the first stirring structure and the second stirring structure. The pushing structure is used to drive the first baffle to move, so that the first strip hole is pushed and scraped and cleaned by the protrusion, so that the material impurities stuck in the first strip hole can be loosened; it also enables the first baffle to move smoothly to the corresponding position, and the first strip hole is in a smooth state, so that effective drainage and water discharge can be performed.

[0052] Furthermore, if Fig.13 As shown, the push structure 500 includes a lead screw 570, a first slide seat 550, a second slide seat 560, a first support plate 510, a second support plate 520, a third support plate 530, and a fourth support plate 540; the lead screw 570 is provided with two threaded sections 571 with opposite textures, and the first slide seat 550 and the second slide seat 560 are respectively correspondingly arranged at the two threaded sections 571; one end of the first support plate 510 is fixedly mounted on the first slide seat 550 by bolts, and one end of the second support plate 520 is fixedly mounted on the second slide seat 560 by bolts; one end of the third support plate 530 is rotatably connected to the end of the first support plate 510 through a rotating shaft, and the other end is rotatably connected to one end of the fourth support plate 540 through a rotating shaft, and the other end of the fourth support plate 540 is rotatably connected to the end of the second support plate 520 through a rotating shaft;

[0053] It adopts a lead screw structure as the main driving component, and multiple lead screws are connected to the output shaft of the second motor through a chain sprocket assembly. On the one hand, it can adapt to the design of the groove so that it can be better stored inside the groove without affecting the rotation of the external stirring structure; on the other hand, the rotation can be used to drive the first slide seat and the second slide seat to move, so that the multiple support plates form an effect of arching outward in the middle, thereby playing a role of pushing. The overall structure is more ingenious and compact, reducing space occupation, and facilitating the design and layout of the overall structure.

[0054] More specifically, when it is used in conjunction with the first stirring structure and the second stirring structure, it specifically includes the following steps:

[0055] S1, the first motor drives the first stirring structure and the second stirring structure to rotate and swing to a preset angle, so that the push plate swings to a position corresponding to the push structure;

[0056] S2, the second motor starts to rotate forward, driving the push structure, so that the third support plate and the fourth support plate arch and protrude outward, and the push plate moves toward the center of the water tank, overcoming the blocking force formed by the material stuck in the first strip hole, so that the push plate moves to the center of the water tank; and the material stuck in the first strip hole is pushed and loosened;

[0057] S3, the second motor starts to reverse, driving the lead screw to reverse, so that the third support plate and the fourth support plate move closer to the groove direction and retract to a preset position without affecting the movement of the first stirring structure and the second stirring structure;

[0058] It should be pointed out that when the first material-pickling member rotates to the groove position, the material is accumulated on the first scraper at this time, and the material fragments may be pressed at the first strip hole, and even a jamming problem may occur, so that the push plate at this position cannot be smoothly moved to the required position. Therefore, a push structure is set to actively intervene and adjust to prevent blocking; and in accordance with the direction of rotation of the stirring structure, the force on the push plate gradually decreases in the direction of rotation, so that after one push, the material fragments can be loosened to facilitate subsequent falling;

[0059] Furthermore, the lead screw 570 is mounted above the filter 160, the middle part of the lead screw 570 corresponds to the position of the filter 160, and the middle part of the lead screw 570 is fixedly sleeved with a brush roller 580. The length of the brush roller 580 is greater than the length of the filter 160, and the bristles of the brush roller 580 slide against the surface of the filter 160; based on the design of the push structure, utilizing the position of the lead screw and the rotational movement during normal operation, the brush roller is arranged to cooperate with the filter at the overflow port, and when the lead screw rotates, the filter is cleaned by the brush roller to prevent clogging.

[0060] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein, and other embodiments falling within the claims of this application are within the scope of protection of the present invention.
