Description

Technical Field

[0001] This disclosure relates to the field of battery production technology, and in particular to a spiral feeding and washing device for battery powder. Background Technology

[0002] Many pieces of equipment are used in the production of ternary lithium batteries. In the stage of washing and dissolving the cathode material of ternary lithium batteries, a water washing and stirring tank is generally used. The existing water washing and stirring tank is generally used to mix the battery powder and water at the same time by stirring the impeller. However, the battery powder is usually washed and dissolved in batches, with the amount of battery powder dissolved in a batch generally around 1 ton. Since the battery powder is sticky, when a batch of battery powder and water are added to the water washing and stirring tank at the same time, it is easy to form powder clumps. Thicker powder clumps not only affect the mixing effect of the battery powder, but also increase the water washing and dissolving time of the battery powder and the energy consumption of the water washing and stirring tank.

[0016] In one embodiment, the vortex generator includes a water pipe, a pressurized nozzle, and a flow divider. The water pipe is welded to the cylinder body, one end of the water pipe is located outside the cylinder body and communicates with the water supply assembly, and the other end of the water pipe extends to the inside of the cylinder body.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] Please see Figures 1 to 11 To better understand the spiral feeding and washing apparatus 10 for battery powder disclosed herein, the following further explanation of the spiral feeding and washing apparatus 10 for battery powder is provided:

[0049] A spiral feeding and washing device 10 for battery powder according to one embodiment includes a cylinder 100, a spiral baffle 200, and a water curtain generator 300. One end of the cylinder 100 has a feed inlet 102, and the other end has a discharge outlet 104. One end of the feed inlet 102 is connected to a feeding assembly (not shown), and one end of the discharge outlet 104 is connected to a liquid tank (not shown). The spiral baffle 200 is disposed inside the cylinder 100, and a spiral guide groove 106 is formed between the spiral baffle 200 and the cylinder 100. One end of the spiral guide groove 106 is connected to the other end of the feed inlet 102, and the other end of the spiral guide groove 106 is connected to the other end of the discharge outlet 104. The water inlet of the water curtain generator 300 is located on the outside of the cylinder 100. The water inlet of the water curtain generator 300 is connected to the water supply component. The water outlet of the water curtain generator 300 is located inside the cylinder 100. The water outlet of the water curtain generator 300 is located between the feed inlet 102 and the spiral guide channel 106.

[0050] In this embodiment, battery powder is fed into the feed inlet 102 via the feeding assembly. Simultaneously, water is supplied to the water curtain generator 300 via the water supply assembly, causing the water curtain generator 300 to form a water curtain between the feed inlet 102 and the spiral guide channel 106 (e.g., ...). Figure 6 The A mark in the middle causes the battery powder to fall onto the water curtain to form a mixed liquid. As the mixed liquid flows into the spiral guide channel 106, it will continuously collide with the cylinder 100 and the spiral baffle 200 when it rotates and flows in the spiral guide channel 106, so that the mixed liquid can be fully mixed, thereby improving the mixing effect of the battery powder.

[0051] Furthermore, by continuously feeding battery powder through the feeding component and continuously supplying water to the water curtain generator 300 through the water supply component, the mixed liquid continuously flows into the spiral guide channel 106. After passing through the spiral guide channel 106, the mixed liquid flows into the liquid tank for storage through the discharge port 104. This enables continuous feeding of battery powder, avoids the battery powder from clumping, shortens the water washing and dissolving time of the battery powder, and improves the mixing effect of battery powder without the need for additional stirring equipment, thereby reducing the energy consumption of the spiral feeding water washing device 10.

[0052] It should be noted that, compared with traditional washing devices, the spiral feeding water washing device 10 disclosed herein can avoid the risk of metal particles being introduced during the stirring process by the metal blades when washing and dissolving battery powder, thus ensuring the purity of the mixed liquid.

[0053] like Figure 3 , Figure 7 , Figure 8 , Figure 9 As shown, in one embodiment, the spiral baffle 200 includes a fixed frame 210, a fixed shaft 220, and a spiral baffle 230. The fixed frame 210 is disposed adjacent to the discharge port 104. The side end of the fixed frame 210 is fixedly connected to the inner wall of the cylinder 100. The top end of the fixed frame 210 is connected to one end of the fixed shaft 220. The other end of the fixed shaft 220 extends into the feed port 102. One end of the spiral baffle 230 is spirally arranged along the peripheral side wall of the fixed shaft 220, and the other end of the spiral baffle 230 is spirally arranged along the inner wall of the cylinder 100. It is understandable that by fixing the side end of the fixing frame 210 to the inner wall of the cylinder 100, the fixing frame 210 is stably installed inside the cylinder 100. Then, by installing one end of the fixing shaft 220 on the top of the fixing frame 210, the fixing shaft 220 can be suspended inside the cylinder 100 through the fixing frame 210. Finally, by spirally arranging one end of the spiral baffle 230 along the peripheral side wall of the fixing shaft 220 and spirally arranging the other end of the spiral baffle 230 along the inner wall of the cylinder 100, a spiral guide channel 106 can be formed inside the cylinder 100. At the same time, the mixed liquid is prevented from leaking out from the gap between the spiral baffle 230 and the cylinder 100. When the mixed liquid rotates and flows in the spiral guide channel 106, it can continuously collide with the spiral baffle 230, the fixing shaft 220 and the cylinder 100, so that the mixed liquid can be fully mixed and the mixing effect of the battery powder can be improved. Furthermore, the presence of a perforated area on the fixed frame 210 does not affect the feeding of the mixed liquid, ensuring the normal operation of the spiral feeding washing device 10. Further, in this embodiment, the fixed frame 210, fixed shaft 220, spiral baffle 230, and cylinder 100 can be made of stainless steel or PVE plastic, ensuring good structural stability. When the fixed frame 210, fixed shaft 220, spiral baffle 230, and cylinder 100 are made of stainless steel, the mixed liquid will continuously collide with the fixed shaft 220, spiral baffle 230, and cylinder 100 as it rotates and flows within the spiral guide channel 106. The impact force is insufficient to wear down the stainless steel, thus ensuring good structural strength of the spiral feeding washing device 10 while preventing the introduction of additional metal into the mixed liquid.

[0054] like Figure 8 and Figure 9As shown, in one embodiment, the fixing frame 210 includes a central fixing block 2110 and a plurality of fixing rods 2120. The central fixing block 2110 is welded to one end of the fixing shaft 220, one end of each of the plurality of fixing rods 2120 is welded to the side end of the central fixing block 2110, and the other end of each of the plurality of fixing rods 2120 is welded to the inner wall of the cylinder 100. It is understandable that by suspending the central fixing block 2110 in the center of the cylinder 100, and by welding one end of several fixing rods 2120 to the side of the central fixing block 2110 and the other end of several fixing rods 2120 to the inner wall of the cylinder 100, the central fixing block 2110 can be stably and suspended in the center of the cylinder 100. Then, by welding one end of the fixing shaft 220 to the top of the central fixing block 2110, the fixing shaft 220 can be stably suspended in the center of the cylinder 100, thereby ensuring that the spiral baffle 200 has good structural stability and that the channel size of the spiral guide groove 106 is consistent, further improving the mixing effect of the battery powder.

[0055] like Figure 2 and Figure 9 As shown, in one embodiment, one end of the spiral baffle 230 is welded to the peripheral sidewall of the fixed shaft 220, and the other end of the spiral baffle 230 is welded to the inner wall of the cylinder 100. It is understood that welding one end of the spiral baffle 230 to the peripheral sidewall of the fixed shaft 220 and the other end to the inner wall of the cylinder 100 improves the connection stability between the spiral baffle 230 and the fixed shaft 220, as well as the connection stability between the spiral baffle 230 and the cylinder 100. This, in turn, improves the structural stability of the spiral baffle 200 and the connection stability between the spiral baffle 200 and the cylinder 100, effectively enhancing the structural stability of the spiral feeding washing device 10.

[0056] like Figure 6 , Figure 7 , Figure 10As shown, in one embodiment, the water curtain generator 300 includes an annular water pipe 310, an inlet pipe 320, a plurality of outlet pipes 330, and a plurality of water curtain nozzles 340. One end of the inlet pipe 320 and one end of the plurality of outlet pipes 330 are connected to the annular water pipe 310, and the other end of the inlet pipe 320 is connected to the water supply assembly. The plurality of outlet pipes 330 are all welded to the cylinder 100, and the other end of the plurality of outlet pipes 330 extends to the inner side of the cylinder 100. Each water curtain nozzle 340 is installed on the other end of the corresponding outlet pipe 330. Understandably, the water supply assembly introduces water from the inlet pipe 320 into the annular water pipe 310, then the annular water pipe 310 distributes the water to each outlet pipe 330, and finally, each water curtain nozzle 340 sprays water out, forming a semi-circular water curtain. Multiple semi-circular water curtains together constitute a water curtain (e.g., Figure 6 The A marking in the designation ensures that the battery powder comes into contact with the water curtain during its descent to form a mixed liquid. Furthermore, by welding the water outlet pipe 330 to the cylinder 100, and connecting one end of the water inlet pipe 320 and one end of several water outlet pipes 330 to the annular water pipe 310, the connection stability between the water curtain generator 300 and the cylinder 100 is effectively improved. Further, in this embodiment, by controlling the feeding amount and speed of the feeding assembly and the water output of the water curtain nozzle 340, the ratio of battery powder to water is controlled, ensuring that the battery powder and water are mixed proportionally. This also enables continuous feeding of the battery powder, avoids clumping, and significantly shortens the water washing and dissolution time of the battery powder, thereby improving production efficiency.

[0057] like Figure 6 and Figure 7 As shown, in one embodiment, a plurality of water curtain nozzles 340 are arranged at equal intervals along the inner periphery of the cylinder 100. The water sprayed from the plurality of water curtain nozzles 340 is directed towards the centerline of the cylinder 100. It can be understood that by arranging the plurality of water curtain nozzles 340 at equal intervals along the inner periphery of the cylinder 100, and ensuring that the water spraying direction of the plurality of water curtain nozzles 340 is consistently directed towards the centerline of the cylinder 100, the thickness of the water curtain formed by each water curtain nozzle 340 forming a semi-circular water curtain is uniform, further improving the mixing effect of the battery powder.

[0058] like Figures 4 to 7As shown, in one embodiment, the spiral feeding washing device 10 further includes a vortex generator 400. The water inlet of the vortex generator 400 is located on the outside of the cylinder 100 and is connected to the water supply assembly. The water outlet of the vortex generator 400 is located on the inside of the cylinder 100, and is situated between the feed inlet 102 and the spiral guide channel 106. It can be understood that the water supply assembly provides water to the vortex generator 400, and the water outlet of the vortex generator 400 outputs a fan-shaped water curtain (e.g., ...) from its outlet. Figure 5 (marked with B), while the fan-shaped water curtain acts on the water curtain (such as...) Figure 5 Within the area marked (A), battery powder falls into the water curtain to form a mixed liquid. Simultaneously, the fan-shaped water curtain provides a swirling impact force to the mixed liquid, improving the dispersion of the battery powder and further enhancing its mixing effect. Furthermore, in this embodiment, the number of swirling generators 400 is two.

[0059] like Figure 5 , Figure 7 and Figure 11 As shown, in one embodiment, the vortex generator 400 includes a water pipe 410, a pressurized nozzle 420, and a flow divider 430. The water pipe 410 is welded to the cylinder 100. One end of the water pipe 410 is located outside the cylinder 100 and is connected to the water supply assembly. The other end of the water pipe 410 extends to the inside of the cylinder 100. The pressurized nozzle 420 is installed on the other end of the water pipe 410, and the flow divider 430 is installed on the water outlet end of the pressurized nozzle 420. Understandably, water is supplied through the water supply assembly via the water pipe 410 to the pressurized nozzle 420, where it is output as high-pressure water. Since the spray direction of the pressurized nozzle 420 is downwards, a flow divider 430 with an inclined surface is installed to change the flow direction of the high-pressure water from the pressurized nozzle 420, causing the high-pressure water to flow towards the centerline of the cylinder 100 and form a high-pressure fan-shaped water curtain (e.g., ...). Figure 5 (marked with B), through a high-pressure fan-shaped water curtain (such as...) Figure 5 The B-marker) acts on the water curtain (e.g. Figure 5 The swirling force provided by the swirling nozzle (marked with "A") further enhances the dispersion of battery powder in the mixture, thereby improving the mixing effect of the battery powder. Furthermore, welding the water pipe 410 to the cylinder 100 improves the connection stability between the swirling generator 400 and the cylinder 100. In this embodiment, the swirling effect provided by the high-pressure fan-shaped water curtain is controlled by adjusting the pressure output of the pressurized nozzle 420 and the water flow rate of the water supply assembly, thereby improving the mixing effect of the battery powder.

[0060] like Figure 3 and Figure 4 As shown, in one embodiment, the spiral feeding washing device 10 further includes a grid plate 500, which is disposed inside the feed inlet 102, and the periphery of the grid plate 500 is welded to the inner wall of the cylinder 100. It can be understood that by setting the grid plate 500, the input amount of battery powder is controlled, achieving continuous feeding of battery powder while ensuring good mixing effect of the battery powder.

[0061] like Figure 1 and Figure 2 As shown, in one embodiment, the spiral feeding washing device 10 further includes a feed hood 600. One end of the feed hood 600 is welded to one end of the cylinder 100, and the other end of the feed hood 600 has a feed inlet 602. One end of the feed inlet 602 is connected to the feed assembly, and the other end of the feed inlet 602 is connected to one end of the feed port 102. It can be understood that by providing the feed hood 600 to cover the feed port 102, the sealing performance of the spiral feeding washing device 10 is improved, while allowing the battery powder input through the feed inlet 602 to have a buffer space to fall, thus preventing battery powder blockage.

[0062] like Figure 3 and Figure 7 As shown, in one embodiment, the spiral feeding washing device 10 further includes a guide bucket 700, which is disposed inside the cylinder 100. The periphery of the guide bucket 700 is welded to the periphery of the inner wall of the cylinder 100. The guide bucket 700 is located between the feed inlet 102 and the spiral guide channel 106, and the guide bucket 700 forms a flow outlet 702, which is connected to both the feed inlet 102 and the spiral guide channel 106. It can be understood that after the battery powder falls into the water curtain to form a mixed liquid, the mixed liquid flows through the flow outlet 702 of the guide bucket 700 to the spiral guide channel 106, ensuring the smooth flow of the mixed liquid while ensuring that the mixed liquid can flow from one end of the spiral guide channel 106 to the other end, so that the mixed liquid can fully collide with the cylinder 100, the fixed shaft 220 and the spiral baffle 230, further improving the mixing effect of the battery powder.

[0063] like Figure 2 , Figure 3 and Figure 8 As shown, in one embodiment, the spiral feeding washing device 10 further includes a discharge funnel 800. One end of the discharge funnel 800 is welded to the other end of the cylinder 100, and the other end of the discharge funnel 800 forms a discharge port 802. One end of the discharge port 802 is connected to the liquid tank, and the other end of the discharge port 802 is connected to one end of the discharge outlet 104. It can be understood that the mixed liquid flowing out through the spiral guide channel 106 is guided to the liquid tank for collection through the discharge port 802 of the discharge funnel 800, thereby completing the discharge operation of the mixed liquid.

[0064] Please see Figures 1 to 11 The feeding assembly feeds battery powder into the cylinder 100 through the feed inlet 602 of the feeding hood 600. The battery powder passes through the grating plate 500 and enters the cylinder 100. The water supply assembly then supplies water to the water curtain generator 300 and the vortex generator 400. The water curtain generator 300 sprays water towards the centerline of the cylinder 100 to form a water curtain (e.g., ...). Figure 5 (marked with A), allowing the battery powder and water to fully mix and form a mixture liquid, while the cyclone generator 400 creates a high-pressure fan-shaped water curtain (such as... Figure 5 The B-marker) acts on the water curtain (e.g. Figure 5 The mixture is marked with "A" and provides swirling force to the mixed liquid, causing it to fall onto the guide hopper 700. The mixed liquid flows into the spiral guide channel 106 through the flow outlet 702 of the guide hopper 700. In the spiral guide channel 106, the mixed liquid will continuously collide with the cylinder 100 and the spiral baffle 200, improving the mixing effect of the battery powder. Finally, the mixed liquid flows to the liquid tank through the discharge outlet 802 of the discharge funnel 800.

[0065] Compared with the prior art, this disclosure has at least the following advantages:

[0066] 1. Battery powder is fed into the feed inlet through the feeding assembly. At the same time, water is supplied to the water curtain generator through the water supply assembly, so that the water curtain generator forms a water curtain between the feed inlet and the spiral guide channel. The battery powder falls onto the water curtain to form a mixed liquid. As the mixed liquid flows into the spiral guide channel, it will continuously collide with the cylinder and the spiral baffle when it rotates and flows in the spiral guide channel, so that the mixed liquid can be fully mixed, thereby improving the mixing effect of the battery powder.

[0067] 2. The battery powder is continuously fed by the feeding component and the water supply component continuously supplies water to the water curtain generator, so that the mixed liquid flows continuously into the spiral guide channel. After passing through the spiral guide channel, the mixed liquid flows into the liquid tank for storage through the outlet. This enables continuous feeding of battery powder, avoids the battery powder from sticking together, shortens the water washing and dissolving time of battery powder, and improves the mixing effect of battery powder without the need for additional stirring equipment, thus reducing the energy consumption of the spiral feeding water washing device.

[0068] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
