[0026] Reference Figures 1 to 5A sedimentation device for cleaning slurry includes a sedimentation tank 1, an outlet pipe 2, and an inlet pipe 3. The sedimentation tank 1 is equipped with a primary sedimentation chamber 4 and a secondary sedimentation chamber 5, which are connected to each other, providing a finer stratified sedimentation environment for the sedimentation process of cleaning wastewater. The outlet pipe 2 passes through the secondary sedimentation chamber 5, with its lower end extending out of the sedimentation tank 1. Both the outlet pipe 2 and the inlet pipe 3 are used to connect the sedimentation tank 1 to a feeding tank 10. The inlet pipe 3 is connected to the upper end of the feeding tank 10, and the inlet pipe 3 is connected to the lower end of the feeding tank 10. This allows the cleaning wastewater in the feeding tank 10 to flow into the sedimentation tank 1 through the inlet pipe 3. The cleaning wastewater contains slurry sediment, which settles in the primary sedimentation chamber 4 and the secondary sedimentation chamber 5. The relatively clear cleaning water in the upper layer of the secondary sedimentation chamber 5 then flows into the feeding tank 10 through the outlet pipe 2, so that the feeding tank 10 can be circulated and cleaned, realizing the multiple use of cleaning water and preventing slurry sediment from flowing into the feeding tank 10. Inside; meanwhile, the water inlet pipe 3 is located outside the sedimentation tank 1, and can be connected to the die head pipe using a quick-release clamp to connect the sedimentation tank 1 and the feeding tank 10. The water inlet pipe 3 is also connected to the primary sedimentation chamber 4, allowing clean wastewater to flow into the primary sedimentation chamber 4. Once full, the wastewater overflows into the secondary sedimentation chamber 5, achieving secondary sedimentation of the clean wastewater and preventing slurry sediment from settling at the bottom of the feeding tank 10. Furthermore, the primary sedimentation chamber 4 and the secondary sedimentation chamber 5 are respectively externally connected to a first drain valve 61 and a second drain valve 6. 2. After cleaning, connect the discharge pipe to the first drain valve 61 and the second drain valve 62 of the primary sedimentation chamber 4 and the secondary sedimentation chamber 5. Open the first drain valve 61 and the second drain valve 62 to discharge the upper layer of clean water in the sedimentation device. Then remove the sedimentation device for easier use. The slurry sediment settles at the bottom of the sedimentation device and can be removed for reuse. The first drain valve 61 and the second drain valve 62 are positioned opposite to the water inlet pipe 3 to facilitate cleaning of the sedimentation tank 1. By using the sedimentation device of this utility model, the cleaning efficiency of the feed tank 10 is effectively improved. At the same time, it can avoid the problem of slurry accumulating in the feed tank and affecting the battery coating quality. It can also reuse the cleaned sediment, effectively saving production costs.

[0027] Reference Figure 3 , Figure 4In this embodiment of the present invention, the sedimentation tank 1 includes an outer tank wall 11, an inner tank wall 12, a tank bottom 13, and a tank cover 14. The bottom ends of the outer tank wall 11 and the inner tank wall 12 are both connected to the tank bottom 13. The inner tank wall 12 is disposed inside the outer tank wall 11, and the height of the inner tank wall 12 is less than the height of the outer tank wall 11. The lower half of the outer tank wall 11 and the inner tank wall 12 enclose a primary sedimentation chamber 4, forming a stepped sedimentation structure. This allows the clean wastewater in the primary sedimentation chamber 4 to flow naturally into the secondary sedimentation chamber 5 for secondary deep sedimentation after primary sedimentation, thereby achieving graded filtration. The height of the outlet pipe 2 is less than the height of the inner tank wall 12, ensuring that the outlet pipe 2 only draws relatively clear clean water from the upper layer of clean wastewater after two stages of sedimentation. This effectively prevents insufficiently settled suspended slurry sediment in the primary sedimentation chamber 4 from being sucked into the feed tank 10, thus ensuring the quality of the clean water.

[0028] Furthermore, the inner barrel wall 12 is provided with an opening 121, the two ends of which are connected to the outer barrel wall 11. The inner barrel wall 12 divides the inner cavity of the sedimentation tank 1 into a primary sedimentation chamber 4 and a secondary sedimentation chamber 5, allowing the cleaning wastewater to settle sequentially in the two chambers. The primary sedimentation chamber 4 performs preliminary sedimentation of the slurry sediment in the cleaning wastewater, removing most of the larger particles of slurry sediment. The secondary sedimentation chamber 5 further settles the fine particles, thereby improving the overall sedimentation effect and making the cleaning water that finally flows into the feed tank 10 from the outlet pipe 2 clearer, preventing slurry sediment from flowing into the feed tank 10. It also facilitates the connection between the second drain valve 62 and the secondary sedimentation chamber 5 when the second drain valve 62 is fixedly installed on the outer barrel wall 11, so as to release the cleaning water in the secondary sedimentation chamber 5.

[0029] The lid 13 is fastened to the upper end of the outer barrel wall 11. The removable lid design facilitates cleaning and maintenance of the inside of the sedimentation tank 1, and also makes it easy to observe the sedimentation situation inside the sedimentation tank 1.

[0030] Reference Figure 1 In this embodiment of the present invention, the bucket lid 14 includes a fixed lid 141, a flip lid 142, and a flip hinge 143. The flip lid 142 is rotatably connected to the fixed lid 141 via the flip hinge 143. During use, the operator can flexibly open the flip lid 142 as needed to inspect and clean a portion of the interior of the sedimentation tank 1 without having to fully open the entire lid, making operation more convenient. Furthermore, the fixed lid 141 and the flip lid 142 are connected together and fit the outer barrel wall 11. A sealing ring is installed on the lid 13 to ensure the sealing between the lid 13 and the sedimentation tank 1, preventing leakage of cleaning water during sedimentation and also preventing external impurities from entering the sedimentation tank 1 and affecting the sedimentation effect.

[0031] Specifically, the upper outer wall of the sedimentation tank 1 is evenly provided with multiple mounting buckles 7, and the fixed cover 141 and the flip cover 142 are provided with hooks 144. The mounting buckles 7 are engaged with the hooks 144. The buckle connection method not only makes installation and disassembly convenient and reduces the difficulty of operation, but also makes the operation simpler and faster than traditional bolt connection methods, saving time and effort. At the same time, the even distribution of multiple mounting buckles makes the connection between the tank cover 13 and the sedimentation tank 1 more stable. There is a sealing ring between the tank cover 13 and the outer tank wall 11. The sealing ring is embedded in the edge of the tank cover 13. The tank cover 13 and the outer tank wall 11 are directly fastened and pressurized by the sealing ring, which further enhances the sealing performance of the sedimentation tank 1.

[0032] Reference Figure 1 , Figure 2 In an embodiment of this utility model, the bottom of the sedimentation tank 1 is provided with an installation connection assembly 8. The installation connection assembly 8 includes a connecting plate 81 and a plurality of fixing parts 82. The connecting plate 81 is connected to the outside of the outer tank wall 11 and is used for installation connection between the sedimentation tank 1 and the feeding tank 10. It also provides a stable installation base for the fixing parts 82, allowing the plurality of fixing parts 82 to be spaced apart on the connecting plate 81, thereby further enhancing the connection stability between the sedimentation tank 1 and the feeding tank 10.

[0033] Specifically, the connecting plate 81 is annular and is fitted onto the outside of the outer barrel wall 11, so that the lower end of the sedimentation tank 1 is completely inside the feeding tank 10, ensuring a tight connection between the sedimentation tank 1 and the feeding tank 10. This also allows the fixing members 82 to be evenly distributed around the sedimentation tank 1, ensuring uniform force distribution when the sedimentation tank 1 is connected to the feeding tank 10, thus guaranteeing the stability of the cleaning process. Furthermore, multiple reinforcing blocks 83 are provided between the connecting plate 81 and the outer barrel wall 11, further strengthening the connection between the connecting plate 81 and the outer barrel wall 11, preventing separation of the connecting plate 81 from the outer barrel wall 11 during use, and improving the reliability of the entire installation and connection assembly 8.

[0034] Specifically, the fixing component 82 includes a bending plate 821 and a rotating handle 822. One end of the bending plate 821 is fixedly connected to the connecting plate 81, and the rotating handle 822 is threadedly connected to the other end of the bending plate 821. A pressure block 823 is provided at the end of the rotating handle 822. The pressure block 823 is used to abut against the outer wall of the feeding tank. With the adjustable structure of the pressure block 823 and the rotating handle 822, the sedimentation device can be fixed above material cylinders of various diameters, which has a certain degree of compatibility and versatility.

[0035] Reference Figure 1In this embodiment of the utility model, handles 9 are provided on the side end of the outer barrel wall 11 and the upper end of the barrel cover 14, making the handling and movement of the sedimentation tank 1 easier and more flexible. Operators can choose the appropriate handle according to the actual situation, avoiding the operational difficulties caused by the inconvenience of a single handle position, improving work efficiency and reducing labor intensity. The inner wall of the outer barrel wall 11 and the inner barrel wall 12 are provided with an anti-stick coating, which can effectively prevent the slurry sediment in the cleaning wastewater from adhering to the barrel wall of the sedimentation tank 1 during the sedimentation process, reducing the residue of sediment and reducing the difficulty of cleaning.

[0036] Reference Figure 1 In the embodiments of this utility model, both the first drain valve 61 and the second drain valve 62 are configured as electromagnetic control valves, which are remotely controlled by electrical signals to realize automated operation. This not only improves the accuracy of operation and avoids errors that may be caused by human operation, but also allows them to be linked with other automated equipment to realize the automated operation of the sedimentation device, thereby improving the automation level and efficiency of the entire production process.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
