Description

Technical Field

[0001] This utility model relates to the field of nickel sulfate crystal processing technology, specifically to a device for reducing the silicon content in nickel sulfate crystals. Background Technology

[0002] Nickel sulfate, also known as nickel alum, is an important nickel salt that appears as blue or green crystals and is soluble in ethanol and ammonia. It exists in nature in three forms: anhydrous, hexahydrate, and heptahydrate.

[0003] In existing technologies, nickel sulfate crystals are used in batteries. When nickel sulfate crystals are used in batteries, since they contain silicon, the silicon on the nickel sulfate crystals is treated to prevent the silicon from reacting with the electrolyte during battery charging and discharging, increasing internal resistance, and damaging the positive electrode material structure due to volume expansion. This ensures battery cycle life and improves electrode reaction stability.

[0004] However, when reducing the silicon content in nickel sulfate crystals, precipitation may be used to treat the silicon. However, the amount of precipitant added may be difficult to control precisely, leading to the co-precipitation of nickel ions, which reduces the nickel recovery rate and introduces new impurity ions. The colloidal silica particles formed during the precipitation process are difficult to settle and filter quickly. Therefore, we propose a device to reduce the silicon content in nickel sulfate crystals. Utility Model Content

[0015] 1. By placing the washing chamber into the collar, pouring nickel sulfate crystals and pure water into the washing chamber, starting the motor, and rotating the drive disc, the movable arm will move in a circular motion along the edge of the drive disc, thereby driving the collar to move laterally back and forth on the base. This causes the gear to mesh with the tooth groove when the collar moves, and the brake lever will start to rotate. At the same time, during the reciprocating motion, the nickel sulfate crystals and pure water in the washing chamber will shake, which allows the nickel sulfate crystals to mix and collide fully with the pure water at about 50 degrees Celsius, and the silicon-containing impurities attached to the crystal surface will be removed by the water flow.

A positioning rod 18 is provided at one end of the protrusion 111, and one end of the protrusion 111 is fixedly connected to one end of the positioning rod 18. The bottom end of the positioning rod 18 is engaged with the inner wall of the top end of the side plate 19. The top end of the positioning rod 18 is fixedly connected to one side of the washing chamber 12. An L-rod 112 is provided at one end of the bottom support 17, and one end of the bottom support 17 is connected to the L-rod 112. The bottom end is fixedly connected, and the top end of the L rod 112 is provided with a motor 113. The top end of the L rod 112 is fixedly connected to the outside of the motor 113.

One side of the sleeve 11 is fixedly connected to one end of the drain port 116.

[0027] This device for reducing the silicon content in nickel sulfate crystals features a rectangular base 17 with a cavity 11 on its top side. Rollers on the cavity 11 can reciprocate laterally on the base 17. Inside the cavity 11 is a chuck 14 with multiple protruding rods on its top side, each corresponding to a hole at the bottom of the washing chamber 12. Therefore, by placing the washing chamber 12 into the collar and engaging it with the chuck 14, and simultaneously... The washing chamber 12 is internally designed with a brake lever 13. During insertion, the brake lever 13 needs to pass through the chuck 14 and the sleeve cavity 11 respectively, and finally enter the center of the gear 15. The bottom end of the brake lever 13 is cross-shaped. After entering the gear 15, the cross-shaped action allows the gear 15 and the brake lever 13 to become one unit. At this time, nickel sulfate crystals are poured into the washing chamber 12, and pure water at about 50 degrees Celsius is also poured into the washing chamber 12. Since the inner side of the base 17 has a toothed groove 16, The tooth groove 16 and the gear 15 are in a meshing state. Then, by starting the motor 113, the output end of the motor 113 is fixedly connected to the drive disk 114. At the same time, the edge of the drive disk 114 is designed with a movable arm 115. The other end of the movable arm 115 is connected to one side of the sleeve cavity 11. So when the drive disk 114 rotates, the movable arm 115 will move in a circle along the edge trajectory of the drive disk 114, thereby driving the sleeve cavity 11 to move laterally back and forth on the base 17. During this process, the gear 15, under the engagement of the brake rod 13, makes the gear 15 mesh with the tooth groove 16 when the sleeve cavity 11 moves, and then the brake rod 13 starts to rotate. At the same time, during the reciprocating motion, the nickel sulfate crystals and pure water in the washing chamber 12 will shake. Therefore, under the action of rotation and shaking, the nickel sulfate crystals can be fully mixed and collided with the pure water at about 50 degrees, allowing the silicon-containing impurities attached to the crystal surface to be removed under the action of water flow, thereby effectively reducing the silicon content in the nickel sulfate crystals.

[0028] A positioning rod 18 is installed on one side of the washing chamber 12, and a side plate 19 is designed on one side of the sleeve cavity 11. Therefore, by combining the positioning rod 18 with the side plate 19, the position of the washing chamber 12 will not shift after entering the sleeve cavity 11, thereby ensuring that the hole can accurately enter the protrusion on the chuck 14. After the washing work is completed, since a telescopic rod 110 is installed on the top side of one end of the side plate 19, the top end of the telescopic rod 110 contacts the protrusion 111, and the protrusion 111 is fixed on the positioning rod 18. Then, by extending the length of the telescopic rod 110, the position of the washing chamber 12 in the sleeve cavity 11 is raised, and the hole is disengaged from the protrusion on the chuck 14. At this time, the water inside will be discharged from the hole, so that the washed nickel sulfate crystals are separated from the water, which is convenient for subsequent draining.

[0029] A drain port 116 is designed on one side of the sleeve cavity 11. When liquid flows out from the washing chamber 12, it will naturally fall into the sleeve cavity 11 and then flow out from the drain port 116. Finally, an L rod 112 is fixedly connected to one end of the base 17. The top of the L rod 112 is fixed to the bottom side of the motor 113. In this way, the L rod can provide stable support for the motor 113, fix the motor 113 on the base 17, and ensure that the position of the motor 113 is fixed when it is running.

[0030] Example 2: Please refer to Figure 1 - Figure 6 The auxiliary mechanism 2 includes a cavity cover 21, an inner plate 22 is provided on the inner wall of the cavity cover 21, the inner wall of the cavity cover 21 is engaged with the outer side of the inner plate 22, and the outer side of the cavity cover 21 is engaged with the inner side of the top of the washing cavity 12.

[0031] A chamber cover 21 is designed at the top of the washing chamber 12, and an inner plate 22 is designed on the inner wall of the chamber cover 21. This allows for easy observation of the nickel sulfate crystals in the washing chamber 12 by pulling up the inner plate 22 during the washing process. At the same time, after washing, the inner plate 22 is pressed down, and its surface sealing structure can tightly fit the inner wall of the chamber cover 21 to prevent liquid from splashing out, ensuring the safety of operators. It can also play a dustproof role during the crystal draining stage, preventing external impurities from re-contaminating the nickel sulfate crystals and further ensuring the purity of the product.

[0032] Please see Figure 1 - Figure 6 By placing the washing chamber 12 into the collar and finally into the center of the gear 15, the gear 15 and the brake lever 13 become one unit. Nickel sulfate crystals are poured into the washing chamber 12, along with pure water at approximately 50 degrees Celsius. Then, the motor 113 is started, and its output end is fixedly connected to the drive disc 114. A movable arm 115 is designed on the edge of the drive disc 114, with the other end of the movable arm 115 connected to one side of the collar 11. Thus, when the drive disc 114 rotates, the movable arm 115 moves along... The edge trajectory of the drive disc 114 makes a circular motion, which in turn drives the sleeve cavity 11 to make a lateral reciprocating motion on the base 17. During this process, the gear 15, under the engagement of the brake lever 13, makes the gear 15 mesh with the tooth groove 16 when the sleeve cavity 11 moves, and then the brake lever 13 starts to rotate. At the same time, during the reciprocating motion, the nickel sulfate crystals and pure water in the washing chamber 12 will shake. Therefore, the nickel sulfate crystals can be fully mixed and collided with the pure water at about fifty degrees, and the silicon-containing impurities attached to the crystal surface can be removed by the water flow.

[0033] By designing an inner plate 22 on the inner wall of the chamber cover 21, the nickel sulfate crystals in the washing chamber 12 can be easily observed by pulling up the inner plate 22 during the washing process. At the same time, after washing, the inner plate 22 can be pressed down, and its surface sealing structure can tightly fit the inner wall of the chamber cover 21 to prevent liquid from splashing out, ensuring the safety of operators, and also playing a dust prevention role during the crystal draining stage.
