Description

Technical Field

[0001] This utility model relates to the field of lithium carbonate battery technology, specifically to a purification device for electrode raw materials of lithium carbonate batteries. Background Technology

[0002] Lithium carbonate batteries are rechargeable lithium-ion batteries that use lithium carbonate as the main lithium source material, synthesize positive electrode active materials such as lithium iron phosphate and ternary materials through high-temperature solid-state method or hydrothermal method, and then match negative electrode, electrolyte and other components. Lithium carbonate battery electrode raw material purification equipment refers to equipment used to remove magnetic metal impurities, non-magnetic foreign matter, and unqualified particles from lithium carbonate and cathode material raw materials, so that their purity reaches battery-grade standards. According to their different purification methods, they are also divided into magnetic separation purification equipment, screening and grading purification equipment, and wet chemical purification equipment, etc.

[0003] However, when using existing drum-type magnetic separation equipment for purifying electrode raw materials for lithium carbonate batteries, the drums on the equipment are in a damp state for a long time. Under this environment, the outer surface of the drum may rust after long-term use, which will affect its electromagnetic adsorption accuracy. In addition, after each use of the equipment, it is necessary to manually clean the impurities remaining on the outer surface of the drum. Therefore, it does not meet the existing requirements. To address this, we propose a new equipment for purifying electrode raw materials for lithium carbonate batteries. Utility Model Content

[0004] The purpose of this utility model is to provide an electrode raw material purification device for lithium carbonate batteries, in order to solve the problems mentioned in the background art, such as the rollers on the equipment being in a damp state for a long time when using existing roller-type magnetic separation electrode raw material purification equipment for lithium carbonate batteries, the outer surface of the rollers used for a long time in this environment may rust, thereby affecting its electromagnetic adsorption accuracy, and the need to manually clean the impurities remaining on the outer surface of the rollers after each use of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a purification device for electrode raw materials of lithium carbonate batteries, comprising a drum-type electromagnetic purification device body, wherein a concave outer shell is fixed on the upper end face of the drum-type electromagnetic purification device body, a single-cylinder is fixedly installed on the upper side inside the concave outer shell, the piston rod of the single-cylinder is connected to a strip plate, and a strip sponge is fixed on the lower end face of the strip plate. The strip-shaped sponge has a rust remover storage groove on both sides above the concave outer shell. The rust remover storage groove contains rust remover. The lower inner wall of the rust remover storage groove has multiple conical grooves. A sealing cover is provided above the conical grooves. A transmission pipe is provided inside the sealing cover. The bottom end of the transmission pipe is fixed inside the strip plate. Both sides of the strip plate are equipped with multiple drying lamps that are fixedly installed on the lower end face of the concave shell.

[0006] Preferably, a sealing sleeve is fixedly fitted on the lower side of the outer surface of the transmission tube, and a sealing groove is provided on the outer side of the top end of the sealing sleeve located on the lower end face of the concave outer shell, and the outer surface of the sealing sleeve is in contact with the inner wall of the sealing groove.

[0007] Preferably, a fixing bracket is fixed on both sides of the upper end face of the sealing cover, and the other end of the fixing bracket is fixed to the lower inner wall of the rust remover storage tank.

[0008] Preferably, an electromagnetic separation drum is provided below the concave outer shell and installed on the outer surface of the main body of the drum-type electromagnetic purification equipment. A control panel is fixedly installed on one side of the electromagnetic separation drum and is electrically connected to the main body of the drum-type electromagnetic purification equipment.

[0009] Preferably, the outer side of the top end of the transmission tube is in contact with the inner wall of the sealing cap, and the transmission tube and the sealing cap are slidably connected.

[0010] Preferably, a sealing cap is provided above the rust remover, located on the upper side inside the rust remover storage tank, and a handle is fixed to the upper end of the sealing cap.

[0011] Preferably, a protective cover plate is provided above the single-cylinder on the upper end face of the concave outer shell, and the concave outer shell and the protective cover plate are fixed together by screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model allows the electromagnetic separating roller to be rotated without stopping after the equipment has finished its daily work. At this time, a single-cylinder pushes the strip sponge downwards, so that it comes into contact with the outer surface of the electromagnetic separating roller. As the outer surface of the rotating electromagnetic separating roller continuously comes into contact with the outer surface of the strip sponge, it can automatically clean the impurities remaining on the outer surface of the strip sponge. The above technical solution enables the equipment to automatically clean the electromagnetic separating roller, thereby increasing the functionality of the equipment. 2. When the strip-shaped sponge is pushed downward by the single-cylinder, the transmission pipe sealed by the sealing cap inside the rust remover will be opened. Then, under the action of gravity, the rust remover will be absorbed by the strip-shaped sponge along the opened transmission pipe. When the electromagnetic separation roller rubs against the strip-shaped sponge, the rust remover absorbed by the strip-shaped sponge will be applied to the outer surface of the electromagnetic separation roller. Through the friction between the strip-shaped sponge and the rust remover, the electromagnetic separation roller can be automatically derusted. The above technical solution can perform rust removal on the electromagnetic separation roller during the daily cleaning process, thereby preventing the accumulation of rust on the outer surface of the electromagnetic separation roller over time, which would affect the electromagnetic adsorption effect of the equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The main body 1 (model eCcMN94b), single-cylinder 5 (model SC-32), and rust remover 9 (model LJ-927) of the drum-type electromagnetic purification equipment mentioned in this utility model can be obtained from the market or through private customization.

[0017] Please see Figures 1 to 4An embodiment of this utility model is provided: an electrode raw material purification device for lithium carbonate batteries, including a drum-type electromagnetic purification device body 1, a concave shell 4 fixed on the upper end face of the drum-type electromagnetic purification device body 1, a single-cylinder cylinder 5 fixedly installed on the upper side inside the concave shell 4, a strip plate 6 connected to the piston rod of the single-cylinder cylinder 5, and a strip sponge 7 fixed on the lower end face of the strip plate 6. On both sides above the strip sponge 7, there is a rust remover storage tank 8 located on the upper end face of the concave shell 4. The inside of the rust remover storage tank 8 contains rust remover 9. The lower inner wall of the rust remover storage tank 8 is provided with multiple conical grooves 10. A sealing cover 11 is provided above the conical grooves 10. A transmission pipe 13 is provided inside the sealing cover 11, and the bottom end of the transmission pipe 13 is fixed inside the strip plate 6. Both sides of the strip plate 6 are provided with multiple drying lamps 14 fixedly installed on the lower end face of the concave shell 4; the lower part of the concave shell 4 is provided with an electromagnetic separation drum 3 installed on the outer surface of the drum-type electromagnetic purification equipment body 1, and a control panel 2 fixedly installed on the outer surface of the drum-type electromagnetic purification equipment body 1 is provided on one side of the electromagnetic separation drum 3, and the control panel 2 is electrically connected to the drum-type electromagnetic purification equipment body 1; the equipment can be controlled through the control panel 2. When the equipment is needed, start the equipment and rotate the electromagnetic separation drum 3. After ensuring that the electromagnetic separation drum 3 runs smoothly without any abnormal noise, feed the slurry evenly and continuously along the direction of the electromagnetic separation drum 3. When the electromagnetic separation drum 3 comes into contact with the slurry, it can automatically adsorb the magnetic material mixed with it. After the electromagnetic separation drum 3 with magnetic material adsorbed on its outer surface rotates from the position in contact with the slurry, it is rinsed by water flow to wash off the magnetic material adsorbed on the outer surface of the electromagnetic separation drum 3. After the equipment finishes its work for the day, do not stop the rotation of the electromagnetic separating roller 3. At this time, the strip plate 6 is pushed down by the single-cylinder cylinder 5. When the strip plate 6 moves down, the strip sponge 7 fixed to it will move down with it. The strip sponge 7 moves down until it is in contact with the electromagnetic separating roller 3. When the outer surface of the rotating electromagnetic separating roller 3 is in contact with the outer surface of the strip sponge 7, it can automatically clean the impurities remaining on the outer surface of the strip sponge 7. The above technical solution enables the equipment to automatically clean the electromagnetic separation roller 3, thereby increasing the functionality of the equipment.

[0018] The outer side of the top end of the transfer pipe 13 is in contact with the inner wall of the sealing cap 11, and the transfer pipe 13 and the sealing cap 11 are slidably connected; the sealing cap 11, whose inner wall is in contact with the outer surface of the transfer pipe 13, can seal the inlet of the transfer pipe 13 located inside the rust remover 9. When the strip plate 6 is pushed downward by the single-cylinder cylinder 5, the transmission pipe 13 fixed to it will move downward along with it. As the transmission pipe 13 descends, the top end of the transmission pipe 13 will leave the inside of the sealing cover 11 and enter the inside of the conical groove 10. When the top end of the transmission pipe 13 enters the inside of the conical groove 10, under the action of gravity, the rust remover 9 will drip through the transmission pipe 13 onto the strip sponge 7 and be absorbed by the strip sponge 7. When the electromagnetic separation roller 3 rubs against the strip sponge 7, the rust remover 9 absorbed by the strip sponge 7 will be applied to the outer surface of the electromagnetic separation roller 3. Then, through the friction between the strip sponge 7 and the rust remover 9, the electromagnetic separation roller 3 can automatically perform rust removal. The above technical solution enables the electromagnetic separation roller 3 to be cleaned and derusted simultaneously during daily cleaning, thereby preventing the accumulation of rust on the outer surface of the electromagnetic separation roller 3 over time, which would affect the electromagnetic adsorption effect of the equipment. After the cleaning operation of the electromagnetic separating roller 3 is completed, the strip plate 6 and strip sponge 7 are pulled back to their original positions by the single-cylinder cylinder 5. As the strip plate 6 moves to its original position, the transmission pipe 13 fixed to it will be inserted into the interior of the sealing cover 11 again to seal the sealing cover 11 and prevent the rust remover 9 from continuing to flow out. After the strip plate 6 and the strip sponge 7 are pulled back to their original positions, the drying lamp 14 is turned on to dry the electromagnetic separation drum 3. After the electromagnetic separation drum 3 is completely dried, the main body 1 of the drum-type electromagnetic purification equipment is turned off and the rotation of the electromagnetic separation drum 3 is stopped.

[0019] A sealing sleeve 15 is fixedly fitted on the lower side of the outer surface of the transmission pipe 13. A sealing groove 16 is provided on the outer side of the top end of the sealing sleeve 15, located on the lower end face of the concave housing 4, and the outer surface of the sealing sleeve 15 is in contact with the inner wall of the sealing groove 16. The sealing sleeve 15 and the sealing groove 16 can enhance the sealing between the transmission pipe 13 and the concave housing 4, thereby preventing the rust remover 9 from flowing out from the position where the transmission pipe 13 contacts the concave housing 4.

[0020] A fixing bracket 12 is fixed on both sides of the upper end face of the sealing cover 11. The other end of the fixing bracket 12 is fixed to the lower inner wall of the rust remover storage tank 8. The fixing bracket 12 fixed to the upper end face of the sealing cover 11 can fix the sealing cover 11 and prevent it from moving.

[0021] The rust remover 9 is provided with a sealing cap located on the upper side of the inside of the rust remover storage tank 8, and a handle is fixed on the upper end of the sealing cap; the sealing cap can seal and protect the rust remover 9 inside the rust remover storage tank 8, preventing foreign objects from contaminating it.

[0022] The single-cylinder cylinder 5 is provided with a protective cover plate located on the upper end face of the concave outer shell 4, and the concave outer shell 4 and the protective cover plate are fixed together by screws; the protective cover plate can seal and protect the single-cylinder cylinder 5, and when the single-cylinder cylinder 5 malfunctions, the protective cover plate can be removed to repair the single-cylinder cylinder 5.
