Description

TECHNICAL FIELD

[0001] The utility model relates to material screening technical field, especially a zirconium bead screening system. BACKGROUND

[0002] The sand mill is a necessary equipment for lithium iron phosphate production, and zirconium beads are used as operating consumables, with large usage and high value. In the grinding process, zirconium beads collide with materials for grinding, and wear and tear and breakage are inevitable. When the zirconium beads break or wear to a certain extent, they are called unqualified products and cannot continue to participate in the grinding work, and need to be screened from zirconium beads with qualified particle size. At the same time, the magnetic foreign matter produced by the wear of the bare metal in the equipment will cause short circuit of lithium ion batteries and even explosion of the batteries, affecting the safety of lithium ion batteries.

[0003] At present, the screening method in the industry is mostly traditional manual screening, and there is no complete zirconium bead screening equipment or system. Such a way generally has the problems of low screening efficiency and low screening quality. Zirconium beads need to be screened once every three months, and screening of a sand mill completely needs to consume 2-3 hours of time of an employee; and does not include metal foreign matter treatment, which has a certain influence on product quality, and a production line often needs to use dozens of sand mills. Therefore, manual screening of zirconium beads is a huge engineering operation and has many disadvantages.

[0032] The utility model will make further detailed description in combination with the drawings of specification and specific embodiment.

[0033] As Figure 1 And Figure 2 Shown: a zirconium bead screening system, including rack assembly 4, feeding assembly 1, screening assembly 2, remove magnetic assembly 3 and collection assembly 5.

[0034] Specifically, the feeding assembly 1 includes a feeding tank for accommodating and guiding the zirconium beads, which can be designed as an inclined or horizontal structure to facilitate the smooth flow of the material. The feeding tank can be, but is not limited to, a cylindrical or funnel-shaped structure. The feeding tank is connected to the screening assembly through a pipeline or channel, and a pneumatic ball valve 6 is arranged on the pipeline or channel to control the flow of the zirconium beads. The pneumatic ball valve 6 is selected because it has the advantages of fast response, high control accuracy, and good sealing performance. The pneumatic ball valve can be instantly opened or closed, and can quickly adjust the flow of the zirconium beads. At the same time, its design can ensure good sealing performance when fully open or fully closed, reducing material leakage.

[0035] Specifically, the screening assembly 2 includes a screening body 21, and at least one filter screen 22 is arranged in the screening body. By replacing filter screens with different mesh sizes, zirconium beads with different particle size requirements can be screened. The inner cavity of the screening body is divided into a qualified area 23 and a non-qualified area 24 by the filter screen 22. The non-qualified area 24 is provided with a waste outlet 25 on one side, so that the unqualified zirconium beads screened by the filter screen 22 enter the non-qualified area 24 and are then discharged through the waste outlet 25. The qualified area 23 is provided with a discharge outlet 26 on one side, which is used to communicate with the demagnetization assembly 3 to further demagnetize the qualified zirconium beads.

[0036] It can be understood that the outer diameter size of the unqualified zirconium beads is usually smaller than that of the qualified zirconium beads. Therefore, the qualified area 23 is arranged above the filter screen 22, and the non-qualified area 24 is arranged below the filter screen 22. For example, when a single-layer filter screen is arranged, the aperture of the filter screen 22 is smaller than the outer diameter size of the qualified zirconium beads and larger than the outer diameter size of the unqualified zirconium beads. In this way, when a certain amount of zirconium beads enter the filter screen of the screening body through the feeding assembly, the qualified zirconium beads that meet the particle size requirements are retained on the filter screen 22, i.e., in the qualified area 23, and then enter the next demagnetization process through the discharge outlet 26. The zirconium beads that do not meet the particle size requirements fall through the filter screen into the non-qualified area 24 below the filter screen and are then discharged through the waste outlet 25. However, this embodiment does not exclude the special case where the outer diameter size of the qualified zirconium beads is smaller than that of the unqualified zirconium beads. Therefore, the mesh size of the filter screen can be set according to the particle size requirements of the zirconium beads, and the number of filter screens can also be set according to the subdivision requirements of the different particle sizes of the zirconium beads. For example, when the particle size of the unqualified zirconium beads needs to be further subdivided, multiple layers of filter screens can be arranged, so that the qualified zirconium beads that meet the particle size requirements are retained on the first layer of filter screens, and the zirconium beads that do not meet the particle size requirements are further screened through the subsequent several layers of filter screens with different apertures. Preferably, the number of filter screens is 1-3.

[0037] In this embodiment, the screening body 21 can be a cylindrical body or a container with other shapes, and the shape and structure of the screening body are not specifically protected in this embodiment.

[0038] In this embodiment, the filter screen 22 is detachably connected to the screening body 21, and the connection method includes but is not limited to threaded connection or clamping. In this way, the filter screen of different mesh sizes can be replaced at any time to achieve the screening of zirconium beads with different particle size requirements.

[0039] In this embodiment, a valve may be provided at the discharge port 26 of the qualified zone of the screening assembly. When a certain number of qualified zirconium beads have accumulated in the qualified zone, the valve is opened to allow the qualified zirconium beads to enter the demagnetization assembly 3. Alternatively, no valve is provided at the discharge port, and the qualified zirconium beads after screening enter the demagnetization assembly 3 directly.

[0040] Specifically, the demagnetization component 3 includes an iron remover 31. The iron remover 31 has a very high magnetic field strength and can effectively adsorb metal foreign matter in the zirconium beads onto the sheet metal. The feed port of the iron remover 31 can be directly aligned with the discharge port of the screening component or connected via a pipeline, so that the zirconium beads enter the iron remover through the feed port of the iron remover to separate the ferromagnetic material. Alternatively, an inclined channel is provided between the feed port of the iron remover and the discharge port of the screening component, and the zirconium beads smoothly enter the iron remover 31 through the inclined channel to separate the ferromagnetic material. It is understandable that since the iron remover is already a prior art, this embodiment does not provide a specific description of its structure.

[0041] Specifically, the collection assembly 5 includes a collection box connected to the discharge port of the iron remover 31. A discharge channel 51 is provided between the discharge port of the iron remover 31 and the collection box to facilitate smooth collection of the demagnetized zirconium beads within the collection box. The discharge channel 51 is designed as an inclined structure, and the end of the discharge channel 51 located at the discharge port of the iron remover is designed as an arc-shaped retaining structure to prevent the zirconium beads from escaping the discharge channel.

[0042] Specifically, the rack assembly 4 can be an integrated design or a modular design. The present embodiment preferably adopts a modular design.

[0043] The following is a preferred embodiment of the modular design of the rack assembly: the rack assembly 4 is divided into an upper rack area 41, a middle rack area 42, and a lower rack area 43, which are arranged separately. The upper rack area 41 houses the feed assembly 1 and its connected pneumatic ball valve 6, the middle rack area 42 houses the screening assembly 2, and the lower rack area 43 houses the collection assembly 5. This modular design allows the three areas to be transported separately or assembled as a whole for easy replacement and maintenance.

[0044] In this embodiment, the racks in each zone are preferably connected by screws. And the discharge port of the pneumatic ball valve 6 in the upper zone of the rack is connected to the feed port of the screening assembly 2 in the middle zone of the rack, such as a flange connection. The iron remover 31 is arranged outside the rack assembly. The iron remover 31 can be separated from the rack assembly, or it can be detachably connected to the middle zone 42 of the rack. The iron remover 31 can be installed at an angle or horizontally. It is only necessary to ensure that the feed port of the iron remover is aligned or connected with the discharge port of the screening assembly to allow qualified zirconium beads to fall in. The discharge channel 51 between the iron remover 31 and the collection assembly 5 can be installed on the lower zone of the rack, or on the outer shell of the iron remover, and extend through the lower zone 43 of the rack to the feed port of the internal collection box.

[0045] It can be understood that in this embodiment, the rack assembly 4 can also be divided into a detachably connected upper rack area and a lower rack area, the upper rack area is provided with a feed assembly 1 and a pneumatic ball valve 6 connected thereto, the lower rack area is provided with a screening assembly 2 and a collecting assembly 5, the screening assembly 2 and the collecting assembly 5 are separated by a partition or a partition frame, in addition, the bottom surface of the lower rack area may not be provided with a bottom plate, and the collection box is placed directly on the ground.

[0046] It is understandable that the racks in each zone can be designed as a frame structure or a closed shell structure according to actual needs. If designed as a closed shell structure, a door body is set on the shell of each zone to facilitate the replacement, installation and maintenance of internal components.

[0047] The working principle of this embodiment is as follows: all components are assembled and fixed, and dry zirconium beads are put into the feeding component 1 manually or by feeding equipment, and enter the screening component 2 through the pneumatic ball valve 6; after the zirconium beads pass through the screening component 2, the zirconium beads with particle size that does not meet the requirements are screened out as unqualified products, and the zirconium beads with particle size that meets the requirements enter the demagnetization component 3 to screen out metal foreign matter in the zirconium beads, and the remaining qualified products flow into the collection component 5, thereby forming a zirconium bead screening system.

[0048] Among them, when the zirconium beads pass through the pneumatic ball valve 6, the flow rate of the zirconium beads can be controlled by controlling the opening and closing amount of the pneumatic ball valve 6. After entering the screening component 2, the filter screen 22 with different mesh sizes can be replaced to achieve screening of zirconium beads with different particle size requirements. Unqualified products will be discharged from the waste port 25, and zirconium beads that meet the particle size requirements will enter the demagnetization component 3 from the discharge port 26 of the screening component 2. The iron remover 31 has a very high magnetic field strength and can effectively adsorb metal foreign matter in the zirconium beads on the sheet metal. Qualified zirconium beads eventually flow into the collection component 5. This system is modular in design, and each module performs its own function. The screening efficiency and quality are significantly improved compared to traditional screening methods.

[0049] Tests have shown that zirconium bead screening is very necessary. For a 450L sand mill filled with 1100Kg of zirconium beads, 60% of the beads can be reused through screening, and the economic benefits generated are: the economic benefit of single maintenance is 1100Kg×0.6×160 yuan / Kg=105,600 yuan; compared with manual screening, taking 40 450L sand mills as an example, manual screening excluding demagnetization requires an employee 120-150 hours, while this system including demagnetization only takes an employee 24-30 hours, saving a lot of time.

[0050] This system is widely applicable to screening operations with different outputs and different zirconium bead particle size requirements. It not only brings economic benefits to companies in the industry, but also effectively improves product production quality.

[0051] Furthermore, the term "connection" should be interpreted broadly. For example, it can include fixed connection, detachable connection, or integral connection; it can include direct connection, indirect connection through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0053] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
