Description

Technical Field

[0001] This utility model relates to the field of material separation device technology, specifically to a ball material separation device. Background Technology

[0002] Ball milling technology, as a core method for material pulverization and nanomaterial preparation, has wide applications in materials science, metallurgy, chemical engineering, and new energy. Laboratory ball milling achieves particle refinement and uniform mixing through the mechanical collision and shearing action between the grinding balls and the material. Especially in wet ball milling, the introduction of a liquid medium effectively reduces the grinding heat effect and inhibits particle agglomeration, significantly improving material dispersibility and reactivity. However, the separation efficiency between the grinding balls and the material after ball milling has long constrained the standardization of experimental procedures and the reproducibility of data. Traditional separation methods (such as vibrating sieving, magnetic separation, or gravity sedimentation) generally face bottlenecks such as screen clogging, grinding ball residue, and long separation cycles when dealing with high-viscosity slurries after wet ball milling. This leads to increased errors in subsequent material characterization (such as particle size analysis and specific surface area testing) and even affects the accurate evaluation of material properties.

[0003] For example, Chinese patent CN 115845992 B discloses a multi-stage separation device based on wet ball milling. It includes a first separator and a second separator with cavities. The second separator divides the cavity of the first separator into a first separation chamber and a second separation chamber connected to the discharge port. The first separation chamber is located between the first and second separators, and the second separation chamber is located within the second separator. The second separation chamber is radially and axially connected to the first separation chamber, forming a first separation channel and a second separation channel, respectively. This invention is applicable to ball-material separation in wet ball milling scenarios and has a multi-stage separation effect. However, the overall size of the equipment is large, the structure is complex, and the manufacturing cost is high. Utility Model Content

[0004] To address the issues that existing ball-material separation devices for wet ball milling are large in size, have complex internal structures to achieve multi-stage separation, and are costly to manufacture, this invention proposes a ball-material separation device with a simple structure, low manufacturing cost, and the ability to separate balls from materials in wet ball milling scenarios.

[0005] To achieve the above-mentioned technical effects, this utility model proposes:

[0006] A ball material separation device includes a tubular separation chamber, one end of which is detachably connected to a sealing cover, and the other end of which is detachably connected to a collection chamber. A screen is provided inside the separation chamber near the collection chamber.

[0007] This utility model aims to simplify the structure of the ball-material separation device and realize the basic function of ball-material separation. The separation chamber and the collection chamber are designed to be detachably connected so that after ball-material separation, the separation chamber and the collection chamber can be disassembled to take out the separated material. The screen is set in the separation chamber and close to the collection chamber, and space is reserved for ball-material separation on the side of the screen in the separation chamber near the sealing cap.

[0008] The separation chamber is threadedly connected to the sealing cover and the collection chamber, respectively. The separation chamber and the sealing cover, and the separation chamber and the collection chamber can be configured to be threadedly connected. The manufacturing process is mature and has a certain degree of sealing performance, which facilitates the disassembly and installation of the various components.

[0009] The separation chamber and the sealing cover are connected by external threads, the sealing cover by internal threads, the separation chamber and the collection chamber by internal threads, and the collection chamber and the separation chamber by external threads. After the sealing cover and the separation chamber are threadedly connected in place, the sealing cover presses its inner bottom surface against the port of the separation chamber. After the opening end of the collection chamber is spirally connected to the separation chamber in place, the screen abuts against the opening end face when feeding, providing some support to the screen during the separation of the ball material.

[0010] A sealing ring is provided between the separation chamber and the sealing cover, and a sealing ring is provided between the separation chamber and the collection chamber. The sealing rings further enhance the sealing performance between the components.

[0011] The collecting chamber is cylindrical, with an open end and a blind end. The open end of the collecting chamber is connected to the separation chamber, and the blind end is spherical. Because the blind end of the collecting chamber is a circular arc spherical surface, the stress at the bottom of the collecting chamber is more uniform during the centrifugal separation of the spherical material.

[0012] The screen is located below 1 / 2 of the overall length of the ball material separator and close to the collection chamber.

[0013] The screen has a layered structure, including a first screen layer and a second screen layer, with the second screen layer located below the first screen layer and close to the collection chamber. This layered design optimizes the separation of granular materials.

[0014] The aperture of the first screen layer is larger than that of the second screen layer, and there is a gap between the first screen layer and the second screen layer.

[0015] The separation chamber, the collection chamber, and the sealing cover are all made of rigid plastic.

[0016] The beneficial effects of this utility model are:

[0017] The overall structure is simple and the manufacturing cost is low; the detachable structure of the separation chamber and the collection chamber facilitates the removal of materials after the separation of the spheres, and the disassembly and installation operations are simple; the single-layer structure of the screen further reduces the cost, and the multi-layer structure can further eliminate material bubbles.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0028] Example 1

[0029] In the prior art, the ball-material separation device for wet ball milling is relatively complex and large in size, making it inconvenient to operate in the experimental process. This embodiment proposes a ball-material separation device with a simple structure and convenient operation. The preferred embodiment of the ball-material separation device is described below.

[0030] Reference Appendix Figure 1 and 2 In this embodiment, the ball material separation device includes a tubular separation chamber 100, with a sealing cover 300 and a collection chamber 200 detachably connected to both ends of the separation chamber 100, and a screen 400 connected in the separation chamber 100.

[0031] The separation chamber 100 has an external thread on its outer surface at one end and an internal thread on its inner surface at the other end. The sealing end cap also has an internal thread on its inner surface and is threaded to the separation chamber 100. The other end face of the separation chamber 100 has an internal thread on its inner surface. The collection chamber 200 has an open end with an external thread at one end and a blind end with a spherical arc surface at the other end. The open end of the collection chamber 200 with the external thread is threaded to the separation chamber 100. A screen 400 is installed in the separation chamber 100, positioned below half the overall length of the ball material separation device and close to the collection chamber 200. The screen 400 is used to separate grinding materials from the balls.

[0032] In this embodiment, the separation chamber 100 and the collection chamber 200 are detachably connected by threads, and the separation chamber 100 and the sealing end cap are detachably connected by threads. This makes operation convenient. During operation, it is ensured that there are no foreign objects inside the collection chamber 200 and that it is tightened with the separation chamber 100. The mixture of ball material and grinding material enters from the other end of the separation chamber 100 and the sealing end cap 300 is tightened. The ball material and grinding material are separated by the screen 400. The grinding material enters the bottom of the collection chamber 200. After separation, the collection chamber 200 and the separation chamber 100 can be unscrewed to remove the grinding material.

[0033] Example 2

[0034] This embodiment provides a ball-material separation device, and the following describes optional embodiments of the ball-material separation device.

[0035] This embodiment further describes the structure of screen 400. (Refer to the attached document.) Figures 1 to 3 The system includes a tubular separation chamber 100, with a sealing cover 300 detachably connected to one end and a collection chamber 200 detachably connected to the other end. A screen 400 is provided inside the separation chamber 100 near the collection chamber 200. The screen 400 has a layered structure, including a first screen layer 401 and a second screen layer 402, wherein the second screen layer 402 is located below the first screen layer 401 and near the collection chamber 200.

[0036] The first screen 400 and the second screen 400 are fitted together. The second screen 400 further eliminates air bubbles in the ground material.

[0037] The collecting chamber 200 is cylindrical, with an open end and a blind end. The open end of the collecting chamber 200 is connected to the separation chamber 100, and the blind end is spherical. The spherical structure of the blind end of the collecting chamber 200 can disperse the stress experienced during the separation process and prevent the collecting chamber 200 from cracking.

[0038] Reference Appendix Figure 3The separation chamber 100 is threadedly connected to the sealing cover 300 and the collection chamber 200. The connection end between the separation chamber 100 and the sealing cover 300 has an external thread, while the sealing cover 300 has an internal thread. The connection end between the separation chamber 100 and the collection chamber 200 has an internal thread, and the connection end between the collection chamber 200 and the separation chamber 100 has an external thread. A mixture of sealing ball material and grinding material is added to the threaded connection between the separation chamber 100, the collection chamber 200, and the sealing cover. After separation, the grinding material is removed. A sealing ring 500 is provided between the separation chamber 100 and the sealing cover 300, and another sealing ring 500 is provided between the separation chamber 100 and the collection chamber 200. The sealing ring 500 prevents leakage during separation and ensures a tight seal. The threaded connection structure facilitates quick assembly and disassembly, and combined with the sealing ring 400, achieves reliable sealing performance to prevent material leakage.

[0039] The screen 400 is located below 1 / 2 of the overall length of the ball material separator and close to the collection chamber 200. After the collection chamber 200 is threadedly connected to the separation chamber 100, the open end of the collection chamber 200 is located inside the separation chamber 100, and the open end of the collection chamber 200 abuts against the second screen 400, providing certain support for the second screen 400.

[0040] In this embodiment, the ball-material separation device has a layered structure for the screen 400. The first screen layer 401 and the second screen layer 402 are used for screening the balls and defoaming the ground materials, respectively, thereby improving separation efficiency. Compared to the single-layer screen structure in Embodiment 1, the layered structure of the screen 400 in this embodiment can further eliminate air bubbles.

[0041] Example 3

[0042] This embodiment provides a ball-material separation device, and the following describes optional embodiments of the ball-material separation device.

[0043] This embodiment provides an optional sieve 400 structure. (See attached document.) Figure 1 , 2 4. A ball material separation device includes a tubular separation chamber 100, one end of which is detachably connected to a sealing cover 300, and the other end is detachably connected to a collection chamber 200. A screen 400 is provided inside the separation chamber 100 near the collection chamber 200. The screen 400 has a layered structure, including a first screen layer 401 and a second screen layer 402, wherein the second screen layer 402 is located below the first screen layer 401 and near the collection chamber 200, wherein the aperture of the first screen layer 401 is larger than that of the second screen layer 402, and a gap exists between the first screen layer 401 and the second screen layer 402.

[0044] There is a certain gap between the first screen layer 401 and the second screen layer 402. After the grinding material is screened by the first screen layer 401, it comes into contact with the second screen layer 402 after passing through a certain distance. The smaller pore size of the second screen layer 402 can effectively eliminate air bubbles in the grinding material. The material regains some kinetic energy in this distance, which is beneficial for defoaming through the fine pores of the second screen layer 402.

[0045] Reference Appendix Figure 2 and 4 The collecting chamber 200 is cylindrical, with an open end and a blind end. The open end of the collecting chamber 200 connects to the separating chamber 100, and the blind end is spherical. The spherical structure of the blind end of the collecting chamber 200 can disperse the stress during the separation process and prevent the collecting chamber 200 from cracking. The separating chamber 100 is threadedly connected to the sealing cover 300 and the collecting chamber 200. The connection end between the separating chamber 100 and the sealing cover 300 has an external thread, and the sealing cover 300 has an internal thread. The connection end between the separating chamber 100 and the collecting chamber 200 has an internal thread, and the connection end between the collecting chamber 200 and the separating chamber 100 has an external thread. The threaded connection between the separating chamber 100, the collecting chamber 200, and the sealing end cover allows for the addition of a mixture of spherical material and grinding material, followed by the removal of the grinding material after separation. A sealing ring 500 is provided between the separating chamber 100 and the sealing cover 300, and a sealing ring 500 is provided between the separating chamber 100 and the collecting chamber 200. The sealing ring 500 is designed to prevent leakage upon separation, ensuring a tight seal. The threaded connection facilitates quick assembly and disassembly, and together with the sealing ring 400, provides reliable sealing performance to prevent material leakage.

[0046] The screen 400 is located below half the overall length of the ball material separator and close to the collection chamber 200. The second screen layer 402 abuts against the opening end of the collection chamber 200, and the opening end of the collection chamber 200 provides some support for the screen 400. The first screen layer 401 is located above the second screen layer 402. In this embodiment, the layered structure of the screen 400 requires extending the length of the separation chamber 100 beyond the original dimensions of Embodiment 2 to ensure that the layered structure of the screen 400 does not affect the capacity of the separation chamber 100.

[0047] Compared to Embodiment 2, in this embodiment, the first screen layer 401 and the second screen layer 402 have a certain gap, that is, the grinding material separates through a certain gap and reaches the second screen layer 402 for contact. The material regains some kinetic energy in this gap, which is beneficial for defoaming through the fine pores of the second screen layer 402.

[0051] Four support blocks 403 are provided on the axial side inside the separation chamber 100. The screen 400 can be placed in the connection end of the screen and the sealing end cover. The screen 400 overlaps on the support blocks 403. The maximum gap between the edge of the screen 400 and the inner wall of the separation chamber 100 is not greater than the aperture of the screen 400.

A sealing ring 500 is provided between the separating chamber 100 and the sealing cover 300, and a sealing ring 500 is also provided between the separating chamber 100 and the collecting chamber 200. The threaded connection structure facilitates quick assembly and disassembly, and combined with the sealing ring 400, it achieves reliable sealing performance to prevent material leakage.

[0053] The screen 400 is located below 1 / 2 of the overall length of the ball material separation device and close to the collection chamber 200. Above the screen 400 is the separation space for the mixture of ball material and ground material. The position of the screen 400 can be adjusted according to actual needs.

[0054] In this embodiment, the screen 400 is detachably connected to the separation chamber 100. The aperture of the screen 400 can be selected according to the actual diameter of the balls, making it suitable for a wider range of applications. In this embodiment, the separation chamber 100, the collection chamber 200, and the sealing cover 300 are all integrally injection molded from rigid plastic, resulting in low mass production costs.

[0055] In some other embodiments, two screens 400 may be added to the separation chamber 100 in sequence, with the screen 400 with a smaller aperture added first and the screen 400 with a larger aperture added later. The structure of the double-layer screens 400 can screen the ball material and defoam it in sequence.

[0056] As an optional embodiment, this embodiment has greater flexibility compared to the above embodiment, and adds one or two steps to the operation.

[0057] Example 5

[0058] This embodiment provides a ball-material separation device, and the following describes optional embodiments of the ball-material separation device.

[0059] This embodiment provides an optional solution, see attached... Figure 1 , 2 6. A ball material separation device includes a tubular separation chamber 100, one end of which is detachably connected to a sealing cap 300, and the other end is detachably connected to a collection chamber 200. A screen 400 is detachably connected to the interior of the separation chamber 100 near the collection chamber 200. The screen 400 has a layered structure, including a first screen layer 401 and a second screen layer 402. Four support blocks 403 are axially arranged inside the separation chamber 100. The first screen layer 401 enters from the connection end between the separation chamber 100 and the sealing cap and overlaps the support blocks 403.

[0060] Reference Appendix Figure 6 The collecting chamber 200 is threadedly connected to the separating chamber 100, and the sealing cover 300 is also threadedly connected to the separating chamber 100. One end of the separating chamber 100 has an external thread that connects to the sealing cover 300, and the other end has an internal thread that connects to the collecting chamber 200.

[0061] When connecting the separation chamber 100 and the collection chamber 200, first place the second screen layer 402 at the port of the collection chamber 200. The outer diameter of the second screen layer 402 is slightly smaller than the inner diameter of the separation chamber 100. After connecting the collection chamber 200 and the separation chamber 100, the second screen layer 402 is positioned between the support block 403 and the collection chamber 200, and is located at the opening end of the collection chamber 200.
