Description

Technical Field

[0001] The present invention relates to the technical field of storage tanks, and particularly to a storage tank for waste lithium battery black powder with a sufficient mixing structure. Background Art

[0002] With the rapid popularization of electric vehicles and portable electronic devices, the usage amount of lithium batteries has increased significantly. After the end of the life cycle of these batteries, the generated waste lithium batteries have also increased sharply. The abandonment of lithium batteries will not only occupy a large amount of land resources, but also may cause serious pollution to the environment. Therefore, it is necessary to safely and efficiently process and store waste lithium batteries.

[0003] Currently, when recycling the cathode material on waste batteries, the battery is first mechanically crushed and separated to obtain cathode sheet materials. Generally, the sheet materials include aluminum sheets and black powder-like active substances adhered thereto. These substances are usually composed of lithium compounds, carbon materials, and impurities. It is necessary to further separate the aluminum sheets and the black powder thereon to reduce the aluminum content in the black powder. The separation method generally includes the following steps: passing the sheet materials to be processed through a vibrating screen, transporting the obtained powder to a cyclone separator through pneumatic conveying, then transporting the materials to a pulse separator, and then transporting the materials obtained in the above steps to a rotary heating drying cylinder through a pipeline. Subsequently, the materials enter a rotary kiln from the rotary heating drying cylinder, and degumming is achieved in the rotary kiln. Then, after the discharge of the rotary kiln is demagnetized by an electromagnet, the particle size of the materials is controlled by a jet mill, and the obtained materials are collected and weighed to improve the uniformity of the materials. Finally, the black powder materials are quantitatively stored in a storage tank, and specific materials are added for mixing at the same time to obtain materials with a large volume and uniformity. Then, the materials in the storage enter the packaging process.

[0004] Existing storage tanks usually add black powder and specific materials such as binders, fillers, conductive agents, and chemical additives successively, and then conduct centralized stirring and mixing. It is difficult to make them fully mixed by stirring, and the mixing effect is poor, which affects the material quality. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The storage cavity of the black powder storage tank of the present invention is composed of a bottom support and a layered tank body, which can perform synchronous mixing during the process of material entry to improve the mixing efficiency. A partition structure is formed in the storage cavity by using the lifting partition plate and the rotating partition plate. The material after mixing is below the lifting partition plate, while the material being mixed is above the lifting partition plate. After the black powder and the specific material are mixed above, the feeding can be stopped. Subsequently, by opening the rotating partition plate, the mixed material can be sent to the lower part. And the partition structure can change the sizes of the two cavities by lifting, and store the mixed material layer by layer. During this process, the mixing and storage are carried out in multiple steps, improving the mixing efficiency and ensuring sufficient mixing of the materials.

[0018] 2. In addition to arranging mixing blades on the lifting partition plate to mix the materials, the present invention can also use air flow to help the powder materials flow in the cavity and promote the uniform mixing of the powder materials. An intake pipe is arranged on the feeding cover. When feeding, first, the air flow is sent into the first branch pipe through the control valve. Multidirectional air flow is formed in the storage cavity by using the mixed flow air groove to disperse the powder materials, and the black powder and the specific material are mixed together in cooperation with the mixing blades. After the mixing is completed, the intake pipe and the second branch pipe are connected through the control valve, and the gas can be blown out from the lower blowing groove to generate pressure to promote the powder materials to fall and enter below the partition structure.

[0019] 3. The feed cover of the present invention is provided with ventilation holes. When generating multi-directional airflows through the mixed-flow air groove, in order to avoid the increase in pressure inside the cavity, the exhaust holes can be opened to connect the storage cavity with the outside, ensuring the gas circulation. And a filter screen is used to prevent the loss of materials. When generating a downward pressure through the downward air groove, the rotation of the telescopic rod drives the movable valve plate to rotate, forming a sealing structure with the fixed valve plate to form a downward pressure inside the storage cavity to accelerate the sedimentation of the powder materials. The telescopic rod is controlled by means of the piston rod, achieving the effect of automatically controlling the gas flow direction.

[0020] 4. The partition structure of the present invention is an opening and closing structure. When the rotating partition rotates to the horizontal state, the lifting partition and the rotating partition separate the storage cavity. When the rotating partition rotates to the downward inclined state, the materials that have been mixed above can fall into the lower part for stable storage. The opening and closing of the rotating partition are also synchronously controlled by the telescopic rod. When the telescopic rod rotates to close the exhaust holes, the rotating partition can automatically rotate downward to open. Therefore, when the second branch pipe intakes air, the rotating partition is in the open state, and the powder materials can fall into the lower part for storage. On the contrary, when the first branch pipe intakes air, the rotating partition is in the horizontal state, cooperating with the lifting partition to complete the separation.

[0033] Please refer to Figures 1 to 10, the present invention provides a technical solution: a storage tank for waste lithium battery black powder with a fully mixed structure, including a storage tank main body. The storage tank main body includes a layered tank body 1 and a bottom support 2. An inlet cover 3 is assembled on the layered tank body 1. A sub-inlet pipe 4 is provided on the inlet cover 3.

A support 14 is assembled on the installation seat 13, and a stirring structure is installed on the support 14. An inlet pipe 17 is installed on the inlet cover 3, and a first branch pipe 18 and a second branch pipe 20 extending below the inlet cover 3 are connected to the inlet pipe 17. A mixing gas groove 19 and a downward blowing gas groove 21 are respectively connected to the first branch pipe 18 and the second branch pipe 20. A control valve 22 is installed on the inlet pipe 17 to control the gas to enter the first branch pipe 18 or the second branch pipe 20. An exhaust hole 23 is provided on the inlet cover 3, and a filter screen 24 is fixedly installed in the exhaust hole 23. A telescopic rod 25 is rotatably installed in the filter screen 24, and a movable valve plate 27 is fixedly installed on the telescopic rod 25. A fixed valve plate 26 is provided in the exhaust hole 23. An opening and closing valve structure is formed by the fixed valve plate 26 and the movable valve plate 27. A piston rod 28 is movably provided near the second branch pipe 20 of the inlet pipe 17, and the piston rod 28 can close the joint of the second branch pipe 20 and the inlet pipe 17 in the initial state. When the piston rod 28 is pushed open by the air flow, it can drive the telescopic rod 25 to rotate, and a winding wheel 35 is installed at the bottom end of the telescopic rod 25. When the winding wheel 35 rotates, it can control the opening and closing angle of the rotating partition 12. When the opening and closing valve structure is closed, the rotating partition 12 opens on both sides of the lifting partition 6.

[0034] As Figure 1 , Figure 2 shown, the bottom support 2 is installed at the bottom of the layered tank body 1, and support feet are provided on the bottom support 2. There are two sub-inlet pipes 4, and the outlet pipe 5 is installed at the center of the bottom of the bottom support 2.

[0035] The storage cavity of the black powder storage tank of the present invention is composed of the bottom support 2 and the layered tank body 1. When storing black powder, the black powder and specific materials such as adhesives are respectively added to the storage cavity from two different sub-inlet pipes 4, and synchronous mixing is carried out during the entry process to improve the mixing efficiency. After the feeding is completed, the inlet cover 3 can be replaced with a sealing cover to ensure that the properties of the black powder mixture remain unchanged after storage. When packaging is required, the mixture is taken out from the outlet pipe 5.

[0036] As Figure 3 , Figure 4As shown, guide rails are installed on the inner wall of the layered tank body 1, and guide grooves 7 are provided on the lifting partition plate 6, and the guide rails are arranged in fit with the guide grooves 7. A nut seat 8 is arranged in the lifting partition plate 6, and a lead screw pair 9 is installed on the feed cover 3. The lead screw pair 9 is driven by a first drive seat 10, and the nut seat 8 is installed on the lead screw pair 9. A telescopic tube 11 is connected between the nut seat 8 and the feed cover 3, and the telescopic tube 11 is sleeved outside the lead screw pair 9.

[0037] The tank body of the black powder storage tank adopts a layered tank body 1. During use, a partition structure is formed in the storage cavity by using the lifting partition plate 6 and the rotating partition plate 12. The material after mixing is below the lifting partition plate 6, while the material during mixing is above the lifting partition plate 6. After the black powder and the specific material are mixed above, the feeding can be stopped. Subsequently, by opening the rotating partition plate 12, the mixed material is sent to the lower part, and the partition structure can change the sizes of the two cavities by lifting. The first drive seat 10 drives the lead screw pair 9 to rotate, so as to control the height of the nut seat 8, drive the lifting partition plate 6 to rise layer by layer, and store the mixed material layer by layer. In this process, the mixing and storage are carried out in multiple steps, improving the mixing efficiency, ensuring sufficient mixing of the material, and a telescopic tube 11 is provided for the lead screw pair 9, which can prevent the powder material from sticking to the upper half of the lead screw pair 9 and affecting the rise of the partition structure. After the mixing is completed, the lead screw pair 9 can be withdrawn from the layered tank body 1 along with the feed cover 3 for cleaning to prepare for the next use.

[0038] As Figure 5 shown, the rotating partition plates 12 are symmetrically arranged on both sides of the lifting partition plate 6, and the rotating partition plates 12 are installed by hinges, and when the rotating partition plates 12 are unfolded, their edges can fit the inner wall of the layered tank body 1.

[0039] The partition structure is an openable and closable structure. When the rotating partition plates 12 rotate to the horizontal state, the lifting partition plate 6 and the rotating partition plates 12 separate the storage cavity. When the rotating partition plates 12 rotate to the lower inclined state, the material that has been mixed above can fall into the lower part for stable storage.

[0040] As Figure 6 shown, a card slot is provided in the mounting seat 13, and the bracket 14 is assembled in the card slot. A second drive seat 15 is installed on the bracket 14, and a mixing blade 16 is connected to the second drive seat 15.

[0041] In the present invention, a mounting seat 13 is provided on the lifting partition plate 6. The bracket 14 is assembled through the mounting seat 13. The second drive seat 15 on the bracket 14 can drive the mixing blade 16 to rotate to continuously mix the black powder and the specific material.

[0042] As Figures 8 - 10As shown, one end of the intake pipe 17 is externally connected to the air pump device, and the other end is movably installed with the piston rod 28. The first branch pipe 18 and the second branch pipe 20 are vertically installed at the bottom of the intake pipe 17. The air outlet of the mixed flow air groove 19 is arranged laterally, and the air outlet of the downward blowing air groove 21 is arranged downward. The control valve 22 is installed at the joint of the first branch pipe 18 and the intake pipe 17.

[0043] In addition to using the mixing blade 16 to mix the materials, the present invention can also use air flow to help the powder materials flow in the cavity and promote the uniform mixing of the powder materials. The intake pipe 17 is provided on the feed cover 3. Air flow is sent into the intake pipe 17 through an air pump. When feeding, first, the air flow is sent into the first branch pipe 18 through the control valve 22. The mixed flow air groove 19 is used to form a multi-directional air flow in the storage cavity to disperse the powder materials, and cooperate with the mixing blade 16 to mix the black powder and the specific material together. After the mixing is completed, the intake pipe 17 and the second branch pipe 20 are connected through the control valve 22, and the gas can be blown out from the downward blowing air groove 21 to generate pressure to promote the powder materials to fall and enter below the partition structure.

[0044] As Figure 10 shown, the exhaust hole 23 is arranged close to the second branch pipe 20, and the telescopic rod 25 is rotatably installed at the center of the filter screen 24. The fixed valve plate 26 and the movable valve plate 27 are mutually attached, and the movable valve plate 27 can rotate with the telescopic rod 25.

[0045] When generating a multi-directional air flow through the mixed flow air groove 19, in order to avoid the pressure in the cavity from rising, the exhaust hole 23 can be opened to connect the storage cavity with the outside to ensure gas circulation, and the filter screen 24 is used to prevent material loss. When generating a downward pressure through the downward blowing air groove 21, the movable valve plate 27 is driven to rotate by the rotation of the telescopic rod 25 to form a sealing structure with the fixed valve plate 26, and a downward pressure is formed in the storage cavity to accelerate the settlement of the powder materials.

[0046] As Figure 9 shown, a spring structure is connected to the piston rod 28. The piston of the piston rod 28 is located in the intake pipe 17, and a rack 29 is fixedly connected to the outer end of the piston rod 28. A driven gear 30 is fixedly installed at the top of the telescopic rod 25, and an intermediate gear 31 is meshed between the driven gear 30 and the rack 29.

[0047] When the control valve 22 guides the air flow into the second branch pipe 20, the pressure of the gas acts on the piston rod 28 to push the piston rod 28, so that the rack 29 on the piston rod 28 moves, driving the intermediate gear 31 to rotate, and then driving the driven gear 30 to rotate, so that the telescopic rod 25 rotates in the middle of the filter screen 24, and the two valve plates close the exhaust hole 23. Then the air flow enters the second branch pipe 20, achieving the effect of automatically controlling the gas flow direction.

[0048] AsFigure 7 As shown, a guide sleeve 32 is fixedly installed on the lifting partition plate 6, and a wire groove is provided in the guide sleeve 32. A lifting rope 33 is movably connected in the wire groove. One end of the lifting rope 33 is fixedly connected to a reel 35. By rotating the reel 35, the lifting rope 33 can be wound up and released. The other end of the lifting rope 33 is fixedly connected to a support plate 34, and the support plate 34 is located below the lifting partition plate 6. Both sides of the support plate 34 are in contact connection with the bottom surface of the rotating partition plate 12.

[0049] At the same time, the opening and closing of the rotating partition plate 12 are also synchronously controlled by the telescopic rod 25. When the telescopic rod 25 rotates to close the exhaust hole 23, the reel 35 at its bottom end rotates synchronously, releasing the lifting rope 33 wound thereon, so that the support plate 34 is lowered and no longer supports the rotating partition plate 12. The rotating partition plate 12 can rotate downward to open. Therefore, while the second branch pipe 20 intakes air, the rotating partition plate 12 is in an open state, and the powder material can fall into the lower part for storage. On the contrary, when the piston rod 28 is reset under the action of the spring structure, the telescopic rod 25 can be reversed, and the lifting rope 33 is wound again through the reel 35, generating a pulling force to lift the support plate 34. The support plate 34 can lift the rotating partition plate 12, so that the rotating partition plate 12 cooperates with the lifting partition plate 6 to complete the separation.

[0050] The spring structure adopts an elastic member including a spring. The elastic member is installed in the intake pipe 17. One end of the elastic member is connected to the inner wall of the intake pipe, and the other end is connected to the piston of the piston rod 28. The elastic force of the elastic member can keep the piston rod 28 in balance. Under the action of air pressure, the piston rod 28 can move against the elastic force of the elastic member. After the air pressure disappears, the elastic force of the elastic member can act on the piston rod 28, enabling it to overcome the meshing transmission resistance and pipeline friction force to completely reset, winding the lifting rope 33 again by the same length, and realizing the complete retraction of the rotating partition plate.

[0051] When the present invention is in use: First, the storage cavity of the black powder storage tank of the present invention is composed of a bottom support 2 and a layered tank body 1. When storing black powder, the black powder and specific materials such as adhesives are respectively added into the storage cavity from two different sub-feed pipes 4, and synchronous mixing is carried out during the entry process to improve the mixing efficiency. After the feeding is completed, the feed cover 3 can be replaced with a sealing cover to ensure that the properties of the black powder mixture remain unchanged after storage. When packaging is required, the mixture is taken from the discharge pipe 5. The tank body of the black powder storage tank adopts a layered tank body 1. During use, a partition structure is formed in the storage cavity by using a lifting partition 6 and a rotating partition 12. The material after mixing is below the lifting partition 6, while the material during mixing is above the lifting partition 6. After the black powder and specific materials are mixed above, the feeding can be stopped. Subsequently, by opening the rotating partition 12, the mixed material is sent to the lower part, and the partition structure can change the sizes of the two cavities by lifting. The first driving seat 10 drives the lead screw pair 9 to rotate, thereby controlling the height of the nut seat 8 and driving the lifting partition 6 to rise layer by layer, and storing the mixed material layer by layer. In this process, the mixing and storage are carried out in multiple steps to improve the mixing efficiency, ensure sufficient mixing of the material, and a telescopic tube 11 is provided for the lead screw pair 9, which can prevent the powder material from sticking to the upper half of the lead screw pair 9 and affecting the rise of the partition structure. After mixing is completed, the lead screw pair 9 can be withdrawn from the layered tank body 1 along with the feed cover 3 for cleaning and preparation for the next use. The partition structure is an openable and closable structure. When the rotating partition 12 rotates to the horizontal state, the lifting partition 6 and the rotating partition 12 separate the storage cavity. When the rotating partition 12 rotates to the lower inclined state, the material that has been mixed above can fall into the lower part for stable storage. The present invention is provided with a mounting seat 13 on the lifting partition 6, and the bracket 14 is assembled through the mounting seat 13. The second driving seat 15 on the bracket 14 can drive the mixing blade 16 to rotate to continuously mix the black powder and specific materials. In addition to using the mixing blade 16 to mix the material, the present invention can also use air flow to help the powder material flow in the cavity and promote the uniform mixing of the powder material. An air inlet pipe 17 is provided on the feed cover 3, and air flow is sent into the air inlet pipe 17 through an air pump. When feeding, first, the air flow is sent into the first branch pipe 18 through the control valve 22, and a multi-directional air flow is formed in the storage cavity by using the mixed-flow air groove 19 to disperse the powder material, and the black powder and specific materials are mixed together with the cooperation of the mixing blade 16. After mixing is completed, the air inlet pipe 17 and the second branch pipe 20 are connected through the control valve 22, and the gas can be blown out from the lower air blowing groove 21 to generate pressure to promote the powder material to fall and enter the lower part of the partition structure. When generating a multi-directional air flow through the mixed-flow air groove 19, in order to avoid the pressure in the cavity from rising, the exhaust hole 23 can be opened to connect the storage cavity with the outside, ensure gas circulation, and use the filter screen 24 to prevent material loss. When generating a downward pressure through the lower air blowing groove 21,Then, the rotation of the telescopic rod 25 drives the rotation of the movable valve plate 27 to form a sealing structure with the fixed valve plate 26, creating a downward pressure in the storage cavity to accelerate the settlement of the powder material. When the control valve 22 introduces the air flow into the second branch pipe 20, the pressure of the gas acts on the piston rod 28 to push the piston rod 28, causing the rack 29 on the piston rod 28 to move, driving the rotation of the intermediate gear 31, and then driving the rotation of the driven gear 30, so that the telescopic rod 25 rotates in the middle of the filter screen 24, and the two valve plates close the exhaust hole 23. Subsequently, the air flow enters the second branch pipe 20, achieving the effect of automatically controlling the gas flow direction. At the same time, the opening and closing of the rotating partition 12 are also synchronously controlled by the telescopic rod 25. When the telescopic rod 25 rotates to close the exhaust hole 23, the reel 35 at its bottom rotates synchronously, releasing the lifting rope 33 wound around it, so that the support plate 34 is lowered and no longer holds the rotating partition 12, and the rotating partition 12 can rotate downward to open. Therefore, when the second branch pipe 20 intakes air, the rotating partition 12 is in the open state, and the powder material can fall down for storage. On the contrary, when the piston rod 28 resets under the action of the spring structure, the telescopic rod 25 can be reversed, and the lifting rope 33 is rewound through the reel 35 to generate a pulling force to lift the support plate 34. The support plate 34 can lift the rotating partition 12, enabling the rotating partition 12 to cooperate with the lifting partition 6 to complete the separation.,

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
