Description

Technical Field

[0001] This utility model relates to the field of zirconium ball cleaning technology, and in particular to a circulating zirconium ball cleaning device. Background Technology

[0002] When preparing battery cathode materials using the high-temperature solid-state method, the raw materials used must be ground using a sand mill. After being ground to a certain particle size standard, they can be transferred to the next production process. During the production of cathode materials, the sand mill may become clogged due to factors such as the instability of the raw materials and the temperature fluctuation of the grinding chamber during the grinding process. Whenever the sand mill becomes clogged, the slurry in the grinding chamber and the zirconium balls are removed from the grinding chamber together, and then the zirconium balls are separated separately. In order to improve grinding efficiency, the zirconium balls must be cleaned thoroughly.

[0003] The existing zirconium ball cleaning device cleans the zirconium balls, then dries them in a dryer, and then loads them into a sand mill. That is, the cleaning and drying processes are carried out by separate equipment, and the transfer of zirconium balls is relatively time-consuming.

[0004] Based on this, we are now studying a zirconium ball cleaning device that integrates cleaning, drying and screening, which improves production efficiency, reduces costs and reduces the floor space required. Utility Model Content

[0005] The purpose of this invention is to provide a circulating zirconium ball cleaning device that integrates cleaning, drying and screening into one unit, thereby improving production efficiency, reducing costs and minimizing floor space required.

[0006] Technical solution: The circulating zirconium ball cleaning device of the present invention includes a cleaning cylinder body with a feed pipe joint installed at the top and a discharge pipe joint at the bottom, a demagnetizing mechanism connected to the cleaning cylinder body, and a screening mechanism connected to the demagnetizing mechanism. A support base is installed below the screening mechanism, and a weighing scale is installed between the support base and the base plate.

[0007] The side wall of the cleaning cylinder body is equipped with a circulation system consisting of circulation pipes and circulation pump, and a hot air dryer is installed on the outside of the circulation system; the screening mechanism is equipped with zircon ball outlets corresponding to different screening materials.

[0008] Furthermore, the device has a water inlet pipe at the top of the cleaning cylinder body and a drain pipe on one side of the lower end of the cleaning cylinder body.

[0009] Furthermore, the screening mechanism of the device includes a screening base and a support installed at the lower end of the screening base. The upper end of the screening base is connected to the demagnetizing mechanism through a flexible joint. A screening screen is provided in the middle position inside the screening base. Screening chambers are provided in both the upper and lower layers of the screening screen. Zirconium ball outlets are respectively located on one side of the upper and lower screening chambers. A vibration motor is installed inside the support, and a counterweight is installed at the lower end of the vibration motor.

[0010] Furthermore, the two ends of the circulation pipeline of the device are connected to the upper and lower ends of the cleaning cylinder body, respectively. The circulation pump is installed on the outer wall of the cleaning cylinder, and the input and output ends of the circulation pump are connected to the circulation pipeline. A three-way valve is installed on the circulation pipeline, and a branch pipe is installed on the three-way valve, which is connected to the air outlet of the hot air dryer.

[0011] Furthermore, the device has an air inlet mesh cover installed at the rear end of the hot air dryer, a fan installed inside the hot air dryer, and an electric heating element installed at the air outlet of the hot air dryer.

[0012] Furthermore, the demagnetizing mechanism of the device contains multiple magnetic rods.

[0013] Furthermore, each of the four corners of the lower end of the cleaning cylinder body of the device is equipped with a support column, and a base plate is installed at the lower end of the support column.

[0014] Beneficial Effects: Compared with existing technologies, the advantages of this invention are as follows: This device integrates cleaning and drying functions by setting a circulation system on the cleaning cylinder body. A certain amount of cleaning fluid is introduced into the cleaning cylinder through the inlet pipe. Then, the circulation pump runs, pumping the bottom cleaning fluid to the top of the cylinder. The circulating flushing action continuously agitates the zirconium balls inside, improving the cleaning effect. After cleaning, wastewater is discharged through the drain valve. The three-way valve on the circulation system switches to the hot air dryer passage, and hot air is introduced into the cleaning cylinder by the hot air dryer to dry the zirconium balls. Cleaning and drying are carried out in the same container, eliminating the need for transfer, which is highly efficient and fast. This solves the problem of time-consuming transfer of zirconium balls during the operation of existing devices where cleaning and drying are separate processes. In addition, by sequentially setting the demagnetizing mechanism, screening mechanism, and weighing scale below the cleaning cylinder, demagnetizing, screening, and weighing operations can be carried out in sequence by the falling discharge, making transfer convenient and highly efficient.

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, the circulating zirconium ball cleaning device of this utility model is used in conjunction with a battery cathode material sand mill. It includes a cleaning cylinder body 1, a feed pipe connector 101 installed on one side of the upper end of the cleaning cylinder body 1, and support columns 103 installed at the four corners of the lower end of the cleaning cylinder body 1. A base plate 104 is installed at the lower end of the support columns 103.

[0022] A circulation system 2 is installed on one side of the cleaning cylinder body 1, and a hot air dryer 3 is installed on the outside of the circulation system 2. An electrically controlled feeding valve 105 is installed below the cleaning cylinder body 1, and a demagnetizing mechanism 4 is installed at the lower end of the electrically controlled feeding valve 105. The demagnetizing mechanism 4 consists of a box and multiple magnetic rods 401 located inside the box. Preferably, they are strong permanent magnet rods. The magnetic rods 401 can remove impurities from the zirconium balls through magnetism.

[0023] A screening mechanism 5 is installed below the demagnetizing mechanism 4, a support base 6 is installed below the screening mechanism 5, a weighing scale 7 is installed between the support base 6 and the base plate 104, and a water inlet pipe 107 is provided at the rear of the upper end of the cleaning cylinder body 1.

[0024] The circulation system 2 includes a circulation pipe 201 and a circulation pump 202. The two ends of the circulation pipe 201 are connected to the upper and lower ends of the cleaning cylinder body 1, respectively. The circulation pump 202 is installed on the outer wall of the cleaning cylinder body 1, and the input and output ends of the circulation pump 202 are connected to the circulation pipe 201. A three-way valve 203 is installed on the circulation pipe 201, and a branch pipe 204 is installed on the three-way valve 203. The branch pipe 204 is connected to the air outlet of the hot air dryer 3.

[0025] The screening mechanism 5 includes a screening base 501 and a support 506. The upper end of the screening base 501 is connected to the demagnetizing mechanism 4 via a flexible joint 502. A screening screen 503 is provided in the middle of the screening base 501. Screening chambers 504 are provided in both the upper and lower layers of the screening screen 503. A zirconium ball outlet 505 is provided on one side of the screening chamber 504. The zirconium ball outlet 505 is connected to the zirconium ball inlet of the sand mill via a pipe. The zirconium balls are loaded into the sand mill using a known pipeline conveying method. The support 506 is installed at the lower end of the screening base 501. A vibration motor 507 is installed inside the support 506. A counterweight 508 is installed at the lower end of the vibration motor 507. An air inlet screen 301 is installed at the rear end of the hot air dryer 3. A fan is installed inside the hot air dryer 3. An electric heating element is installed at the air outlet of the hot air dryer 3.

[0026] A drain valve 106 is installed on one side of the lower end of the cleaning cylinder body 1. A dehumidification valve 102 is installed on the other side of the upper end of the cleaning cylinder body 1. The steam generated during the drying of the zirconium balls can be discharged through the dehumidification valve 102 to avoid excessive internal pressure and secondary moisture caused by water vapor.

[0027] Operating method: Connect the feed pipe connector 101 of the cleaning cylinder body 1 to the discharge pipe of the sand mill. Use conventional pipeline feeding method to send the zirconium balls in the sand mill into the cleaning cylinder body 1. After completion, introduce a certain amount of cleaning fluid into the cleaning cylinder body 1 through the water inlet pipe 107. Then, the circulation pump 202 runs to pump the bottom cleaning fluid to the top of the cylinder. The circulation flushing action continuously agitates the zirconium balls inside, improving the cleaning effect. After cleaning, drain the wastewater through the drain valve 106. Switch the three-way valve 203 on the circulation system 2 to the hot air dryer 3 passage. The hot air dryer 3 introduces hot air into the cleaning cylinder body 1 to dry the zirconium balls.

[0028] After drying, the electrically controlled feeding valve 105 is opened, allowing the zirconium balls to fall sequentially into the demagnetizing mechanism 4 and the screening mechanism 5. When the zirconium balls pass through the demagnetizing mechanism 4, the multiple strong permanent magnet rods 401 inside the zirconium balls can remove impurities through magnetism. When the zirconium balls fall into the screening mechanism 5, the weighing scale 7 first weighs them. Since the upper end of the screening mechanism 5 is connected to the demagnetizing mechanism 4 through the flexible joint 502, the weighing scale 7 can only weigh the screening mechanism 5 and its internal weight. The weight at this time is A. After weighing, the vibrating motor 507 inside the screening mechanism 5 runs. At this time, zirconium balls that do not meet the specifications due to grinding and wear fall from the screening screen 503 to the lower layer, while those that meet the standards remain in the upper layer. After screening, the zirconium balls that meet the standards in the upper layer are discharged first. Then the weighing scale 7 weighs them again to obtain parameter B. Subtracting A from B gives the weight of the zirconium balls that meet the standards. The difference between this value and the preset total weight of zirconium balls can be used to calculate how many zirconium balls need to be added back into the sand mill.
