Description

Technical Field

[0001] This utility model relates to a zirconia ball screening device for impurity removal and demagnetization, belonging to the technical field of zirconia ball screening devices. Background Technology

[0002] The lithium iron phosphate industry mainly uses the iron phosphate process for production. Iron phosphate, lithium carbonate, and a carbon source are mixed, then ground, dried, and sintered before final packaging and shipping. The preparation process involves a grinding step, where the mixed slurry is ground using a grinding mill with zirconium oxide balls to achieve the required particle size. After a period of operation, the zirconium balls wear down, their diameter decreases, or they break, reducing grinding efficiency. Additionally, there is the possibility of raw materials carrying over or magnetic materials from the process mixing with the zirconium balls. Therefore, the zirconium balls require regular maintenance. Currently, the industry uses a manual process: the zirconium balls are manually transferred from the grinding mill to a collection tank, rinsed with pure water, and then agitated with a magnetic rod to remove magnetic impurities. The rinsed zirconium balls are then transferred in batches to a dryer to remove moisture, dried, and recycled for later use.

[0003] In the prior art, a zirconium ball cleaning device disclosed in Chinese invention patent CN109482572A includes a supporting body, a cleaning component, and a screening component. The supporting body is provided with a cleaning space with an opening for accommodating zirconium balls. The cleaning component is connected to the supporting body and is used to emit ultrasonic waves into the cleaning space. The screening component is disposed inside the cleaning space and divides the cleaning space into a screening space and a qualified product cavity connected to the opening. The screening component is used to screen zirconium balls with a radius smaller than a preset radius inside the qualified product cavity to the screening space. The problem with this invention patent is that the zirconium balls used in the lithium iron phosphate industry production process, in addition to producing small-diameter zirconium balls, also include broken zirconium balls, small raw material particles, large raw material particles, and impurities and foreign objects introduced by the raw materials. Simple cleaning cannot remove insoluble impurities, and the screening process can only remove unqualified objects smaller than the preset diameter. Large impurities and large magnetic foreign objects will still remain in the particles that meet the preset diameter, and it cannot remove the metallic magnetic substances mixed in.

[0026] Example 1

[0027] like Figure 1 , Figure 3 As shown, a zirconia ball screening, impurity removal, and demagnetization device includes a feeding hopper 1, which is funnel-shaped and used for temporarily storing and discharging untreated zirconia balls. A feeding port 11 is provided at the top of the feeding hopper 1 for discharging the balls. A screening component 2 is connected to the bottom of the feeding hopper 1, and the top of the screening component 2 is connected to the feeding hopper 1.

[0028] The magnetic separation component 3 includes a magnetic separation plate 31. A permanent magnet plate 35 is provided at the bottom of the magnetic separation plate 31 to adsorb magnetic impurities. The zirconia balls are demagnetized and recycled, making full use of the zirconia balls, improving utilization rate, saving resources, reducing production costs, and saving manual screening, thus improving work efficiency.

[0029] Example 2

[0030] Improvements based on Example 1: such as... Figures 1 to 4As shown, the screening assembly 2 includes a screening box 21, a first screen 22, a second screen 23, a first discharge port 24, a second discharge port 25, and a third discharge port 26. The top of the screening box 21 is connected to the feeding hopper 1. The screening box 21 is equipped with the first screen 22 and the second screen 23. The first screen 22 has sieve holes for separating large particles of impurities and zirconia balls. The first discharge port 24 is located on the side of the first screen 22, penetrating the screening box 21, and is used to discharge large particles of impurities. The large particles of impurities are blocked by the first screen 22, while the zirconia balls and smaller impurities fall into the second screen 23 through the sieve holes of the first screen 22. The second screen 23 has a second discharge port 25 on its side wall, penetrating the screening box 21. The second screen 23 has sieve holes for separating complete zirconia balls from worn and non-standard zirconia balls and small particles of impurities. The complete zirconia balls are separated by the first screen 24. The screen openings of the second screen 23 are blocked, and the material is discharged from the second outlet 25 through vibration and falls onto the magnetic separation plate 31. The worn zirconia balls and small particles that do not meet the specifications fall into the bottom of the screening box 21 through the screen openings. The bottom side wall of the screening box 21 is connected to the third outlet 26, and the worn zirconia balls and small particles that do not meet the specifications are discharged from the screening box 21 through the third outlet 26. Several springs 27 are arranged around the bottom of the outer wall of the screening box 21. The springs 27 are used to support the screening box 21 and reduce the dynamic load and noise during vibration. The bottom of the springs 27 is connected to the screening base 28 to fix the screening assembly 2. The screening base 28 is equipped with a vibration motor 29 for driving the vibration of the screening box 21. The diameter of the zirconia balls is 0.3~0.8mm, so the mesh number of the first screen 22 can be 20 mesh~35 mesh, and the mesh number of the second screen 23 can be 35 mesh~60 mesh.

[0031] Furthermore, the second discharge port 25 is connected to the magnetic separation plate 31 through flexible connections such as hoses and funnels, so that the zirconia balls roll down automatically.

[0032] like Figure 3 , Figure 4 As shown, the magnetic separation assembly 3 includes a magnetic separation base 33, and the magnetic separation plate 31 is inclined to facilitate the automatic downward rolling of the zirconia balls. The inclined bottom of the magnetic separation plate 31 is hinged to the magnetic separation base 33, and the magnetic separation base 33 is used to support and fix the magnetic separation plate 31.

[0033] Furthermore, an adjustment component 32 is provided on the magnetic separation base 33. The upper end of the adjustment component 32 is rotatably connected to the magnetic separation plate 31. The adjustment component 32 can adjust the tilt angle of the magnetic separation plate 31 by extending or shortening.

[0034] Furthermore, the magnetic separation plate 31 is an inverted trapezoid, wider at the top and narrower at the bottom, with the sides of the magnetic separation plate 31 rolled upwards to gather the sliding zirconia balls;

[0035] Furthermore, a protective cover 34 is provided on the magnetic separation plate 31, and a number of permanent magnet plates 35 are provided on the lower wall of the protective cover 34. There is a cavity between the bottom of the protective cover 34 and the magnetic separation plate 31, and the cavity allows the zirconia balls to pass through. During the downward movement of the zirconia balls, the permanent magnet plates 35 adsorb magnetic impurities in the zirconia balls, and the protective cover 34 can prevent the introduction of environmental impurities and prevent the zirconia balls from splashing out.

[0036] Furthermore, the protective cover 34 is transparent, allowing observation of the permanent magnet plate 35 adsorbing magnetic materials without opening the protective cover 34, thus facilitating the maintenance of the permanent magnet plate 35.

[0037] like Figure 1 , Figure 2 As shown, a stirring motor 12 is installed on the feeding hopper 1. The output shaft of the stirring motor 12 extends into the feeding hopper 1 and is connected to a stirring rod 13 for stirring untreated zirconia balls and impurities. A pneumatic hammer 14 is installed on the lower outer wall of the feeding hopper 1 for striking the zirconia balls remaining in the feeding hopper 1.

[0038] A conveying pipe 15 is provided between the feeding hopper 1 and the screening component 2. One end of the conveying pipe 15 is connected to the bottom outlet of the feeding hopper 1, and the other end is connected to the inlet of the screening component 2.

[0039] Furthermore, a flow regulating valve 16 is provided on the conveying pipe 15, which is used to control the feeding speed of the feeding hopper 1.

[0040] A collection component 4 is provided at the discharge port of the magnetic separator 3 to collect intact and compliant zirconia balls for recycling; the bottom of the collection component 4 is equipped with multiple casters 41 to facilitate the transfer of zirconia balls.

[0041] The working principle of this utility model:

[0042] like Figures 1 to 4As shown, during use, untreated zirconia balls are poured into the feeding hopper 1 from the feeding port 11. The stirring motor 12 and the pneumatic hammer 14 are turned on to facilitate the feeding of the zirconia balls. The flow regulating valve 16 is adjusted to control the feeding speed. The untreated zirconia balls fall onto the first screen 22 in the screening assembly 2 through the conveying pipe 15. The vibration motor 29 is turned on. Large particles of impurities are blocked by the first screen 22 and discharged from the screening box 21 through the first discharge port 24 by vibration. Zirconia balls and smaller impurities fall into the second screen 23 through the screen holes of the first screen 22. The intact zirconia balls are blocked by the screen holes of the second screen 23 and discharged from the screening box 21 through the second discharge port 25 by vibration, rolling onto the magnetic separation plate 31. Wear-resistant zirconia balls and small particles that do not meet specifications fall through the sieve holes of the second screen 23 into the bottom of the screening box 21 and are discharged from the screening box 21 through the third discharge port 26, completing the initial size and specification screening. The zirconia balls that have passed the initial screening fall onto the inclined magnetic separation plate 31. The adjustment component 32 is adjusted to control the angle of the magnetic separation plate 31, and the zirconia balls that have passed the initial screening roll down through the inclined magnetic separation plate 31. During the rolling process, the permanent magnet plate 35 on the magnetic separation plate 31 and the protective cover 34 will adsorb the magnetic impurities in the zirconia balls after the initial screening. When the permanent magnet plate 35 is full of magnetic impurities, the upper end of the protective cover 34 is lifted to remove the magnetic impurities. The zirconia balls after magnetic separation roll down to the collection component 4 for reuse.

[0043] However, as is well known to those skilled in the art, the working principles and wiring methods of the stirring motor 12, the pneumatic hammer 14, the flow regulating valve 16, and the vibrating motor are commonplace and belong to conventional means or common knowledge. Therefore, they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
