Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of electrode material production equipment, and particularly relates to a water washing batching device. BACKGROUND

[0002] The battery pole piece is usually prepared by using high-nickel ternary material as raw material. Due to the high content of LiOH and Li2CO3 impurities on the surface of the high-nickel ternary material, the raw material generally needs to be water washed during the preparation process. At present, most manufacturers will use a wet water washing system such as the one disclosed in Chinese patent document CN117358087A to water wash the raw material in batches. In order to ensure the consistency of the water washing effect of the raw material, batching needs to be performed for each batch, and in the process of traditional pipeline batching, the raw material mainly slides along the inner wall of the pipeline under the action of gravity. The above-mentioned way is difficult to control the unloading rate, which may cause the occurrence of material flushing, and finally lead to abnormal batching accuracy. CONTENT OF THE UTILITY MODEL

[0012] In some embodiments, each of the conveying pipes is provided with a discharge section near its end, and there are two washing tanks, with each discharge section connected to one of the washing tanks.

[0013] In some embodiments, the washing tank includes a mixing tank body, a water inlet pipe, a rotary drive, and a stirring paddle. The mixing tank body is connected to the discharge section, and the rotary drive is fixedly installed on the mixing tank body. The stirring paddle is located inside the mixing tank body and connected to the rotating shaft of the rotary drive. The water inlet pipe is connected inside the mixing tank body.

[0014] In some embodiments, the washing tank further includes a sprayer disposed inside the mixing tank; the rotating shaft of the rotary drive passes through the sprayer, and the shaft wall of the rotating shaft is fixedly connected to the sprayer; the water inlet pipe is connected to the interior of the sprayer, and a plurality of spray holes are spaced apart on the outer surface of the sprayer.

[0018] In the aforementioned water washing and batching device, the conveying pipe is horizontally positioned between the feeding hopper and the washing tank, and the vibrator is located close to the feeding section of the conveying pipe. This allows the material entering the feeding section from the feeding hopper to bounce and displace against the bottom of the inner circumferential wall of the conveying pipe under the action of the vibrator. Simultaneously, because a flow-limiting baffle is positioned between the feeding section and the discharge section, a portion of the edge of the flow-limiting baffle and the inner circumferential wall of the conveying pipe form a material passage gap. After the flow-limiting baffle is rotated by the rotary driver, if the material passage gap gradually approaches the bottom of the inner circumferential wall of the conveying pipe, the material can more easily slide through the gap towards the discharge section, accelerating the batching rate. If the material passage gap gradually moves away from the bottom of the inner circumferential wall of the conveying pipe, the material will be obstructed by the flow-limiting baffle, slowing down the sliding rate. This allows for more precise control of the feeding rate, reduces material overflow, and ultimately improves batching accuracy. Attached Figure Description

[0035] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0037] 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.

[0038] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0039] like Figure 1 and Figure 2 As shown, an embodiment of the water washing and batching device includes a feeding bin 100, a conveying pipe 200, a water washing tank 300, a vibrator 400, and a material flow limiting component 500; the feeding bin 100, the conveying pipe 200, and the water washing tank 300 are connected sequentially from top to bottom; the conveying pipe 200 is provided with an inlet 210 and an outlet 220; the inlet 210 is connected to the feeding bin 100, which is used to feed materials; the outlet 220 is connected to the water washing tank 300, which is used to wash materials; the conveying pipe 200 is horizontally arranged between the feeding bin 100 and the water washing tank 300; the vibrator 400 is installed on the conveying pipe. The material flow limiting component 500 is located on the conveying pipe 200 and close to the feed section 210. The material flow limiting component 500 includes a rotary driver 510 and a flow limiting baffle 520. The flow limiting baffle 520 is rotatably disposed inside the conveying pipe 200 and is separated between the feed section 210 and the discharge section 220. A portion of the edge of the flow limiting baffle 520 and the inner peripheral wall of the conveying pipe 200 form a material passage notch 501. The rotary driver 510 is fixedly installed on the conveying pipe 200, and the drive shaft of the rotary driver 510 is connected to the flow limiting baffle 520 to drive the flow limiting baffle 520 to rotate so that the material passage notch 501 is close to or away from the bottom of the inner peripheral wall of the conveying pipe 200.

[0040] It is understandable that, since the conveying pipe 200 is horizontally arranged between the feeding bin 100 and the washing tank 300, and the vibrator 400 is arranged close to the feeding part 210 of the conveying pipe 200, the material entering the feeding part 210 from the feeding bin 100 can jump and displace against the bottom of the inner peripheral wall of the conveying pipe 200 under the action of the vibrator 400. Meanwhile, since the flow-limiting baffle 520 is positioned between the feed section 210 and the discharge section 220, a portion of the edge of the flow-limiting baffle 520 and the inner peripheral wall of the conveying pipe 200 form a material passage gap 501. After the flow-limiting baffle 520 is driven to rotate by the rotary driver 510, if the material passage gap 501 gradually approaches the bottom of the inner peripheral wall of the conveying pipe 200, the material can more easily slide through the material passage gap 501 to the discharge section 220 of the conveying pipe 200, thus accelerating the batching rate. If the material passage gap 501 gradually moves away from the bottom of the inner peripheral wall of the conveying pipe 200, the material will be hindered by the flow-limiting baffle 520, slowing down the sliding rate. This allows for more precise control of the feeding rate, reduces material overflow, and improves batching accuracy.

[0041] Combination Figure 2 As shown, in some embodiments, the flow-limiting baffle 520 has an arc-shaped edge portion 521 and a straight edge portion 522 positioned opposite each other. The arc-shaped edge portion 521 slides against the inner peripheral wall of the conveying pipe 200, and the straight edge portion 522 and the inner peripheral wall of the conveying pipe 200 form a material passage notch 501. It can be understood that since the arc-shaped edge portion 521 of the flow-limiting baffle 520 slides against the inner peripheral wall of the conveying pipe 200, when the rotary driver 510 drives the flow-limiting baffle 520, the arc-shaped edge portion 521 slides relative to the inner peripheral wall of the conveying pipe 200, thereby causing the flow-limiting baffle 520 to rotate within the conveying pipe 200. This allows the straight edge portion 522 to gradually move closer to or further away from the bottom of the inner peripheral wall of the conveying pipe 200, thereby changing the position of the material passage notch 501 formed by the straight edge portion 522 and the inner peripheral wall of the conveying pipe 200 relative to the bottom of the inner peripheral wall of the conveying pipe 200.

[0042] Combination Figure 1 and Figure 3As shown, in some embodiments, the water washing and feeding device further includes a support suspension 600, which includes a support top plate 610 and a support bottom plate 620 connected to each other; the support top plate 610 and the support bottom plate 620 are disposed on opposite sides of the feeding section 210, the vibrator 400 is fixed on the support bottom plate 620, and the feeding bin 100 is installed on the support top plate 610; the feeding section 210 is provided with a feeding branch pipe 211, and the two ends of the feeding branch pipe 211 are respectively connected to the conveying pipe 200 and the feeding bin 100. It is understandable that, since the feed section 210 of the conveying pipe 200 is located between the interconnected support top plate 610 and support bottom plate 620, the feeding bin 100 can be installed on the support top plate 610 and the vibrator 400 can be fixed on the support bottom plate 620. This allows the feeding bin 100, the vibrator 400 and the conveying pipe 200 to be compactly integrated together, thereby increasing the structural strength and reducing the impact of the vibration of the vibrator 400 on the structure of the water washing batching device itself.

[0043] Combination Figure 3 As shown, in some embodiments, a connection interface 6101 is provided on the support top plate 610. The feeding bin 100 and the feeding branch pipe 211 are respectively installed on both sides of the support top plate 610. The feeding bin 100 is connected to the feeding branch pipe 211 through the connection interface 6101. A feed rate regulating valve 611 is provided at the connection interface 6101. It can be understood that, since a feed rate regulating valve 611 is provided at the connection interface 6101, and the feeding bin 100 is connected to the feeding branch pipe 211 through the connection interface 6101, the amount of material passing through the connection interface 6101 can be changed by adjusting the opening degree of the feed rate regulating valve 611. This further avoids excessive material entering the conveying pipe 200 from the feeding chamber, which would increase the burden on the vibrator 400 and affect the normal feeding of the conveying pipe 200.

[0044] Combination Figure 3As shown, in some embodiments, the water washing and feeding device further includes a feed pipe opening and closing assembly 700; the feed pipe opening and closing assembly 700 includes a push-pull driver 710 and a blocking insert 720, and an insertion port 201 is provided on the wall of the feed pipe 200; the blocking insert 720 is slidably inserted into the insertion port 201; a portion of the blocking insert 720 is located between the feed section 210 and the flow limiting baffle 520, and forms an opening 7201 with the inner wall of the feed pipe 200; the push-pull driver 710 is fixedly mounted on the support suspension 600, and the drive rod of the push-pull driver 710 is connected to the blocking insert 720 to drive the blocking insert 720 to slide and close or open the opening 7201. It is understandable that, since the blocking insert 720 is slidably inserted into the inlet 201 on the wall of the conveying pipe 200, the part of the blocking insert 720 located between the feed section 210 and the flow limiting baffle 520 forms an opening 7201 with the inner wall of the conveying pipe 200, so that the push-pull driver 710 can drive the blocking insert 720 to slide at the inlet 201. When the push-pull driver 710 pushes the blocking insert 720, the blocking insert 720 abuts against the inner wall of the conveying pipe 200, thereby closing the opening 7201. At this time, the material in the conveying pipe 200 will be isolated to avoid excessive material from increasing the burden on the flow limiting baffle 520 and causing the flow limiting effect of the flow limiting baffle 520 to decrease, thus affecting the material dispensing accuracy.

[0045] Combination Figure 1 As shown, in some embodiments, each of the conveying pipes 200 has a discharge section 220 near its end, and there are two washing tanks 300, with each discharge section 220 connected to one washing tank 300. It is understood that since the washing tanks 300 require time to prepare materials, by setting up two washing tanks 300, each connected to a discharge section 220 near the end of the conveying pipe 200, the washing operations of the materials can be performed alternately by each washing tank 300. When one washing tank 300 is being prepared, the other washing tank 300 can simultaneously perform the material washing operation, thereby improving the efficiency of the material washing operation.

[0046] Combination Figure 1 and Figure 4As shown, in some embodiments, the washing vessel 300 includes a mixing vessel body 310, a water inlet pipe 320, a rotary drive 330, and a stirring paddle 340. The mixing vessel body 310 is connected to the discharge section 220, and the rotary drive 330 is fixedly mounted on the mixing vessel body 310. The stirring paddle 340 is located inside the mixing vessel body 310 and connected to the rotating shaft 331 of the rotary drive 330. The water inlet pipe 320 is connected inside the mixing vessel body 310. It can be understood that since both the discharge section 220 of the conveying pipe 200 and the water inlet pipe 320 are connected to the mixing vessel body 310, water can enter the mixing vessel body 310 through the water inlet pipe 320, and at the same time, the discharge section 220 of the conveying pipe 200 can introduce materials into the mixing vessel body 310 to mix with water. Furthermore, since the stirring paddle 340 inside the mixing vessel 310 is connected to the rotating shaft 331 of the rotary driver 330, the rotary driver 330 can drive the stirring paddle 340 to rotate to stir the material and water inside the mixing vessel 310, thereby improving the efficiency of material washing.

[0047] Combination Figure 4 As shown, in some embodiments, the washing tank 300 further includes a sprayer 350, which is disposed inside the mixing tank body 310; the rotating shaft 331 of the rotary drive 330 passes through the sprayer 350, and the shaft wall of the rotating shaft 331 is fixedly connected to the sprayer 350; the water inlet pipe 320 is connected to the inside of the sprayer 350, and a plurality of spray holes 3501 are spaced apart on the outer surface of the sprayer 350. It is understandable that since the water inlet pipe 320 is connected to the inside of the sprayer 350, the water inlet pipe 320 can inject water into the inside of the sprayer 350. At the same time, since the shaft wall of the rotating shaft 331 is fixedly connected to the sprayer 350, and several spray holes 3501 are spaced apart on the surface of the sprayer 350, when the washing tank 300 discharges material, the stirring paddle 340 rotates and stirs the material and water. The water is simultaneously dispersed and sprayed out through several spray holes 3501 on the surface of the sprayer 350, which can clean the material hanging on the circumference of the rotating shaft 331, reduce the material residue and prevent the occurrence of process abnormalities.

[0048] Combination Figure 5As shown, in some embodiments, the washing tank 300 is also equipped with an additive dispensing mechanism 800. The additive dispensing mechanism 800 includes a feeding bin 810, a tube vibrating conveying assembly 820 and a premixing bin 830 connected sequentially from top to bottom. The premixing bin 830 is connected to the washing tank 300 and has an inlet 8301. The tube vibrating conveying assembly 820 includes a fixed vibrator 822 and a feed pipe 821. The feed pipe 821 is horizontally arranged between the feeding bin 810 and the premixing bin 830. The first end of the feed pipe 821 is connected to the feeding bin 810 and the second end of the feed pipe 821 is connected to the premixing bin 830. It is understandable that, since the feed pipe 821 is horizontally positioned between the feeding bin 810 and the premixing bin 830, and the vibrator 822 is fixed to the feed pipe 821, the additive in the feeding bin 810 can bounce and displace against the bottom of the inner circumferential wall of the feed pipe 821 under the action of the vibrator 822. This allows the additive to be slowly injected into the premixing bin 830 through the feed pipe 821 and premixed with the water entering from the inlet 8301 to prepare the additive solution. Furthermore, because the premixing bin 830 is connected to the washing tank 300, the additive solution can enter the washing tank 300 and mix with the materials. The additive solution can stabilize the properties of the materials and prevent them from denaturing during the washing process.

[0049] Combination Figure 5 and Figure 6 As shown, in some embodiments, the tube vibratory feeding assembly 820 further includes a torsion driver 823 and a flow-limiting baffle 824; the flow-limiting baffle 824 is rotatably disposed inside the feed pipe 821 and is blocked between the two ends of the feed pipe 821; a portion of the edge of the flow-limiting baffle 824 and the inner peripheral wall of the feed pipe 821 form a dispensing notch 8201; the torsion driver 823 is fixedly installed on the feed pipe 821, and the drive shaft of the torsion driver 823 is connected to the flow-limiting baffle 824 to drive the flow-limiting baffle 824 to rotate so that the dispensing notch 8201 approaches or moves away from the bottom of the inner peripheral wall of the feed pipe 821. It is understandable that, since the flow-limiting baffle 824 is blocked between the two ends of the feed pipe 821, part of the edge of the flow-limiting baffle 824 and the inner peripheral wall of the feed pipe 821 form a dispensing notch 8201. After the flow-limiting baffle 824 is driven to rotate by the torsion drive 823, if the dispensing notch 8201 gradually approaches the bottom of the inner peripheral wall of the feed pipe 821, the additive can more easily slide through the dispensing notch 8201 to the second end of the feed pipe 821 to accelerate the dispensing rate. If the dispensing notch 8201 gradually moves away from the bottom of the inner peripheral wall of the feed pipe 821, the additive will be blocked by the flow-limiting baffle 520 to reduce the sliding rate and slow down. This allows for more precise control of the feeding rate, reduces the occurrence of additive flushing, and thus improves the dispensing accuracy.

[0050] In some embodiments, the rotary driver 510, rotary driver 330, and torsional driver 823 can all be electric motors, pneumatic motors, or hydraulic motors, etc.; the push-pull driver 710 can all be telescopic cylinders, telescopic hydraulic cylinders, or telescopic electric cylinders, etc.; and the vibrator 400 and vibrating tube device 822 can all be traditional electric vibrators or pneumatic vibrators, etc. It should be noted that the above are only illustrative examples and are not intended to be specific limitations. The vibrator 400 and the conveying pipe 200 can be connected in any conventional fixed manner, and the vibrating tube device 822 and the feeding pipe 821 can be connected in any conventional fixed manner; therefore, this disclosure will not elaborate further.

[0051] In some embodiments, for better understanding, the operation of the water washing and mixing device is described below:

[0052] Combination Figure 1 and Figure 2 As shown, the material is first fed into the feeding hopper 100 and then enters the conveying pipe 200 through the feeding section 210. The vibrator 400 is started, causing the conveying pipe 200 to vibrate. The material bounces and moves along the bottom of the inner circumferential wall of the conveying pipe 200 as it vibrates. The drive driver 510 drives the flow-limiting baffle 520 to rotate, so that the material passage gap 501 formed by part of the edge of the flow-limiting baffle 520 and the inner circumferential wall of the conveying pipe 200 gradually approaches the bottom of the inner circumferential wall of the conveying pipe 200. During this process, the material can more easily slide through the material passage gap 501 to the discharge section 220 of the conveying pipe 200, which speeds up the batching rate. When the material passage gap 501 gradually moves away from the bottom of the inner circumferential wall of the conveying pipe 200, it becomes more difficult for the material to pass through the material passage gap 501. At this time, the material batching rate decreases, so that the material can be accurately injected into the mixing vessel 310 through the conveying pipe 200. After the material is fully injected into the mixing vessel 310, the water inlet pipe 320 is opened to inject water into the mixing vessel 310. At the same time, the rotary driver 510 is started to drive the stirring paddle 340 to stir the mixture of material and water to complete the material washing operation.

[0053] Compared with the prior art, this disclosure has at least the following advantages:

[0054] In the aforementioned water washing and batching device, since the conveying pipe 200 is horizontally arranged between the feeding bin 100 and the water washing tank 300, and the vibrator 400 is arranged close to the feeding section 210 of the conveying pipe 200, the material entering the feeding section 210 from the feeding bin 100 can jump and displace against the bottom of the inner peripheral wall of the conveying pipe 200 under the action of the vibrator 400. Meanwhile, since the flow-limiting baffle 520 is positioned between the feed section 210 and the discharge section 220, a portion of the edge of the flow-limiting baffle 520 and the inner peripheral wall of the conveying pipe 200 form a material passage gap 501. After the flow-limiting baffle 520 is driven to rotate by the rotary driver 510, if the material passage gap 501 gradually approaches the bottom of the inner peripheral wall of the conveying pipe 200, the material can more easily slide through the material passage gap 501 to the discharge section 220 of the conveying pipe 200, thus accelerating the batching rate. If the material passage gap 501 gradually moves away from the bottom of the inner peripheral wall of the conveying pipe 200, the material will be hindered by the flow-limiting baffle 520, slowing down the sliding rate. This allows for more precise control of the feeding rate, reduces material overflow, and improves batching accuracy.

[0055] 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 utility model 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.
