[0037] The technical solution of the present invention will be further described below with reference to the drawings and through specific embodiments.

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

[0039] The above-mentioned lead-acid battery recycling and processing device adopts a hierarchical treatment method. In the upstream link, multiple stirrings and flushes are carried out, and the flushing water in the downstream link is used as auxiliary water, which can reduce waste; in the downstream link, clean water is used as the flushing water, combined with the stirring action, which can effectively improve the cleaning of the material fragments and reduce the waste of recyclable substances; and the design and layout of the overall structure can enable the materials to move effectively in a progressive manner, enabling the material fragments to be fully cleaned, and also realizing continuous processing and production, improving efficiency.

[0040] Furthermore, as 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 , Figure 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 Figure 10 , Figure 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] Further, the flushing device includes a pump body, multiple first spray pipes, at least one second spray pipe, and multiple third spray pipes. A plurality of high-pressure nozzles are installed at the bottom of the spray pipes in an array distribution; above the water tank at the end above the first water receiving tray, there are multiple first spray pipes, which are arranged in an arc array distribution and are erected corresponding to the interval positions of the first material pushing members on the water tank; above the middle of the remaining water tanks above the first water receiving tray, one second spray pipe is erected respectively; above the middle of the remaining water tanks, one third spray pipe is erected; the first spray pipe and the second spray pipe converge at the first converging pipe, and the first converging pipe is used to connect to an external high-pressure water source; the third spray pipes are all connected and collected at the second converging pipe, and the second converging pipe is connected to the output port of the pump body through a first pipeline. A first solenoid valve is installed on the first pipeline, and the input port of the pump body is connected to the first water receiving tray through a second pipeline; the first converging pipe and the first pipeline are connected through a third pipeline, and the connection point is located between the first solenoid valve and the second converging pipe. A second solenoid valve is installed on the third pipeline; a liquid level gauge is installed in the first water receiving tray, and the water volume in the first water receiving tray is monitored through the liquid level gauge. When the water volume is within the preset range, the first solenoid valve is opened and 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 spray flushing, 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 spray flushing is performed with the high-pressure solution supplied externally; with the above structural design and layout, the materials are flushed with clean water at at least two water tank positions at the end to clean the end position; and, at the position of the last water tank, multiple first spray pipes are used for multi-point flushing, effectively improving the flushing and cleaning quality and minimizing the discharge of material fragments mixed with sewage; the flushing water overflowing from the water tanks corresponding to the first spray pipe and the second spray pipe parts is relatively clean, and is pumped and pressurized by the pump body to flush the materials at the upstream position and supplement the water volume, which can reduce waste; when the water volume in the first water receiving tray is insufficient, or during the replenishment operation after the sewage is emptied, external water source is required to supplement the flushing water, and the corresponding program is naturally started to conduct the corresponding pipeline;

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

[0046] Further, as Figures 8 to 11As shown, at least two guiding bars 2124 are fixedly provided on the wall surface of the first squeegee 2121 facing the rotating and swinging direction. A push plate 213 is slidably clamped at the guiding bars 2124, and the push plate slides along the guiding bars as the first stirring structure rotates; the position of the push plate will change accordingly when the first stirring structure rotates and swings to different angles. Especially when rotating to a position close to the next water tank, the push plate moves downward to accelerate the downward movement of the top-pushed material fragments; among them, a limit bolt is installed on the top surface of the end of the guiding bar far from the shaft body to prevent the push plate from completely detaching from the guiding bar.

[0047] Furthermore, as Figure 12 shown, a plurality of bumps 2131 are fixedly provided on the bottom surface of the push plate 213. The positions of the bumps 2131 correspond to the positions of the first strip-shaped holes 2123. The bumps 2131 are slidably arranged at the first strip-shaped holes 2123 for cleaning the first strip-shaped holes; the gravity of the push plate can be used to apply a top-pushing force to the material stuck at the first strip-shaped holes, which can play a role in clogging prevention to a certain extent; furthermore, both ends of the bump are in a blade-shaped structure, which can reduce the frictional resistance with the first strip-shaped hole and can also better push the material stuck at the first strip-shaped hole to accelerate the loosening of the material.

[0048] Furthermore, as Figure 5 、 Figure 7 shown, grooves 140 are provided on the top side walls of the upstream side of the water tank 110. The grooves extend along the length direction of the water tank; the overflow port 120 is provided at the grooves 140; by using the grooves as the first part of the overflow, it can play a buffering effect and better guide the overflow liquid to flow towards the overflow port.

[0049] Furthermore, a retaining ring 150 is fixedly provided on the outer side of the top end of the overflow port 120. A filter screen 160 is installed on the top surface of the retaining ring 150 in a covering manner; the retaining ring with a higher setting can limit the specific part of the overflow water. The liquid entering the groove needs to rise above the filter screen before it can enter 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 to play a collecting effect and facilitate drainage; the shape of the filter screen 160 is adapted to the top surface shape of the retaining ring 150. The filter screen is tightly attached to the top surface of the retaining ring for effective filtering; among them, the two ends of the filter screen are fixedly provided with downwardly turned-over flanges, and the flanges are tightly attached to the outer walls of the two ends of the retaining ring and are fixedly connected by bolts. It adopts a dismountable structure, which is convenient for the processing and production of parts, and the assembly is relatively simple.

[0051] Furthermore, as 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 Figure 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 pushing structure, causing the third support plate and the fourth support plate to arch and protrude outward, pushing the pushing plate towards the center of the water tank, overcoming the blocking force formed by the material stuck in the first strip-shaped hole, and moving the pushing plate to the center position of the water tank; and pushing and loosening the material stuck in the first strip-shaped hole.

[0057] S3. The second motor starts to rotate reversely, driving the lead screw to rotate reversely, causing the third support plate and the fourth support plate to 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 noted that when the first feeding member rotates to the groove position, the material is accumulated on this first scraper at this time. The material fragments may press on the first strip-shaped hole, and even cause a jamming problem, making the pushing plate at this place unable to move smoothly to the required position. Therefore, a pushing structure is set up for active intervention and adjustment to prevent blockage; also in line with the rotation direction of the stirring structure, the force on the pushing plate gradually decreases in the rotation direction. Thus, after one push, the material fragments can be loosened for subsequent dropping.

[0059] Furthermore, the lead screw 570 is arranged above the filter screen 160. The middle part of the lead screw 570 corresponds to the position of the filter screen 160. A brush roller 580 is fixedly sleeved on the middle part of the lead screw 570. The length of the brush roller 580 is greater than the length of the filter screen 160. The bristles of the brush roller 580 abut against the surface of the filter screen 160 and slide. Based on the design of the pushing structure, by using the position of the lead screw and the rotation movement during normal operation, a brush roller is set to cooperate with the filter screen at the overflow port. When the lead screw rotates, the filter screen is cleaned by rolling the brush roller to prevent blockage.

[0060] The present invention is described through preferred embodiments. Those skilled in the art know that without departing from the spirit and scope of the present invention, these features and embodiments can be variously changed or equivalently replaced. The present invention is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of this application belong to the scope of protection of the present invention.
