Description

Technical Field

[0001] This utility model relates to the field of material handling technology, and more specifically, to a screening machine. Background Technology

[0002] In the production process of battery materials, screening machines are one of the indispensable key pieces of equipment. Their main function is to screen the size of material particles in the production process to obtain material particles that meet the requirements, thereby ensuring the quality and safety of battery material products.

[0003] Screening machines require regular screen replacement to ensure stability and sieving efficiency. However, the sealing rings currently used in screening machines have limitations during screen replacement. Specifically, operators need to disassemble the old screen and install the new one, inevitably leading to direct contact between the screen structure and the outer structure. This disassembly and assembly process can easily cause violent collisions between the screen structure and the outer structure. Such collisions not only damage the equipment but, more importantly, the magnetic substances generated can mix into the material, resulting in a decline in the quality of battery materials.

[0004] In other words, existing screening machines suffer from damage due to collisions during the assembly and disassembly process. Utility Model Content

[0005] The main purpose of this utility model is to provide a screening machine to solve the problem of equipment damage caused by collisions during the disassembly and assembly process of the screening machine in the prior art.

[0006] To achieve the above objectives, this utility model provides a screening machine. Along the flow path of the material, the screening machine includes a top cover, a first mounting frame, a sealing ring, a screening component, a second mounting frame, and a vibration mechanism. The top cover is located on the first mounting frame, the screening component is located between the first and second mounting frames, and the second mounting frame is located on the vibration mechanism. The sealing ring is arranged circumferentially around the screening component, and the inner wall of the sealing ring is in contact with the outer wall of the screening component. The sealing ring includes a first annular segment and a second annular segment connected to each other, and the outer diameter of the first annular segment is larger than the outer diameter of the second annular segment.

[0007] Furthermore, the screening assembly includes a main structure, which includes a main body section and a radial extension section. The radial extension section is located at one axial end of the main body section and at one end of the main body structure near the first mounting bracket. The radial extension section extends outward along the radial direction of the main body section. A first annular section is fitted onto the radial extension section, and a second annular section is fitted onto the main body section.

[0008] Furthermore, the outer diameter of the main body section is smaller than the inner diameter of the second mounting bracket, and the second annular section is located between the main body section and the second mounting bracket.

[0009] Furthermore, the axial height of the second annular segment is greater than the axial height of the main segment.

[0010] Furthermore, the end of the second annular segment near the second mounting bracket is flush with the end of the main body segment near the second mounting bracket.

[0011] Furthermore, the outer surface of the radial extension segment includes a first surface, a transition surface, and a second surface connected in sequence, and the first annular segment is disposed in conjunction with and covers the first surface, the transition surface, and the second surface.

[0012] Furthermore, the screening assembly includes a main structure, a screen, and a support structure. The main structure includes a flow cavity, and the screen is disposed at the opening of the flow cavity at one end of the main structure near the first mounting frame. The support structure is disposed inside the flow cavity and connected to the cavity wall of the flow cavity. The screen is disposed near the first mounting frame relative to the support structure.

[0013] Furthermore, the support structure includes a support ring and at least two support arms. The two ends of the support arms are respectively connected to the support ring and the cavity wall of the flow cavity, and the at least two support arms are arranged at intervals along the circumference of the flow cavity to form a flow channel between two adjacent support arms.

[0014] Furthermore, the first mounting bracket and the second mounting bracket are detachably connected by an annular connector.

[0015] Furthermore, the sealing ring is made of rubber; or the sealing ring is made of plastic.

[0016] Applying the technical solution of this utility model, along the direction of the material flow path, the screening machine includes a top cover, a first mounting frame, a sealing ring, a screening component, a second mounting frame, and a vibration mechanism; the top cover is located on the first mounting frame, the screening component is located between the first mounting frame and the second mounting frame, and the second mounting frame is located on the vibration mechanism; the sealing ring is arranged circumferentially around the screening component, the inner wall of the sealing ring is in contact with the outer wall of the screening component, and the sealing ring includes a first annular segment and a second annular segment connected to each other, the outer diameter of the first annular segment being larger than the outer diameter of the second annular segment.

[0017] In this application, the vibration mechanism of the screening machine drives the top cover, first mounting frame, screening component, and second mounting frame to vibrate synchronously. This allows the material to pass through the screening component between the first and second mounting frames, separating the material into large particles and qualified particles, effectively achieving material screening and ensuring the continuity and integrity of the screening operation. A sealing ring is circumferentially installed on the screening component, with its inner wall fitting against the outer wall of the screening component. This effectively prevents damage to the outer wall of the screening component from hard collisions during screen replacement, thus preventing magnetic substances generated by collisions from mixing into the material. Specifically, the sealing ring consists of a first annular segment and a second annular segment connected together, with the outer diameter of the first annular segment being larger than that of the second annular segment. This design helps to create an adaptive sealing effect in different parts of the screening component, ensuring a stable seal even under high-frequency vibration of the vibration mechanism, reducing seal failure and material leakage caused by vibration.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] To address the problem of equipment damage caused by collisions during the disassembly and assembly process of existing screening machines, this application provides a screening machine.

[0032] like Figures 1 to 7 As shown, along the direction of the material flow path, the screening machine includes a top cover 10, a first mounting frame 20, a sealing ring 30, a screening component 40, a second mounting frame 50, and a vibration mechanism 60; the top cover 10 is located on the first mounting frame 20, the screening component 40 is located between the first mounting frame 20 and the second mounting frame 50, and the second mounting frame 50 is located on the vibration mechanism 60; the sealing ring 30 is arranged around the circumference of the screening component 40, and the inner wall of the sealing ring 30 is in contact with the outer wall of the screening component 40; the sealing ring 30 includes a first annular segment 31 and a second annular segment 32 connected to each other, and the outer diameter of the first annular segment 31 is larger than the outer diameter of the second annular segment 32.

[0033] When the screening component 40 is removed from between the first mounting frame 20 and the second mounting frame 50, it is prone to collision, which leads to the generation of tiny fragments, i.e. magnetic materials. These magnetic materials fall into the screening machine and mix into the material, causing the material to fail to meet the standards.

[0034] In this application, the vibration mechanism 60 of the screening machine drives the top cover 10, the first mounting frame 20, the screening component 40, and the second mounting frame 50 to vibrate synchronously. This causes the material to pass through the screening component 40 between the first mounting frame 20 and the second mounting frame 50, separating the material into large particles and qualified particles. This effectively achieves the screening of materials by the screening machine, thereby ensuring the continuity and integrity of the screening operation. The screening component 40 is equipped with a circumferential sealing ring 30. The inner wall of the sealing ring 30 is fixedly fitted to the outer wall of the screening component 40, effectively preventing damage to the outer wall of the screening component 40 from hard collisions during screen replacement 45, and thus preventing magnetic substances generated by the collision from mixing into the material. Specifically, the sealing ring 30 is divided into a first annular segment 31 and a second annular segment 32 connected to each other. At the same time, the outer diameter of the first annular segment 31 is larger than the outer diameter of the second annular segment 32. This arrangement helps to form an adaptive sealing effect in different parts of the screening assembly 40. Even under the high-frequency vibration of the vibration mechanism 60, the sealing ring 30 can maintain a stable sealing state, reducing sealing failure and material leakage caused by vibration.

[0035] In such Figure 1 and Figure 5 In the illustrated embodiment, the first annular segment 31 and the second annular segment 32 of the sealing ring 30 can be integrally molded without the need for additional adhesives or other fasteners, which can significantly improve the sealing performance and stability of the sealing ring 30, thereby extending the service life of the entire sealing ring 30.

[0036] Specifically, the sealing ring 30 can be made of an elastic material. For example, the sealing ring 30 can be made of rubber or plastic, giving it wear resistance and corrosion resistance, making it suitable for long-term exposure to chemicals or high-temperature environments. Furthermore, since the sealing ring 30 is made of an elastic material such as rubber or plastic, it can adapt to the size of different models of screening components 40 through its elastic force.

[0037] It should be noted that, as Figure 1 As shown, the screening component 40 is located between the first mounting frame 20 and the second mounting frame 50. The first mounting frame 20 and the second mounting frame 50 are detachably connected by an annular connector, allowing operators to easily replace the screening component 40 by disassembling the annular connector. Optionally, the annular connector can be a clamping ring connector, thereby securing the relative positions of the first mounting frame 20 and the second mounting frame 50; the annular connector can also be a clamp connector, securing the relative positions of the first mounting frame 20 and the second mounting frame 50 by rotation or sliding. Of course, connectors other than clamping ring connectors or clamp connectors can also be used, as long as they can achieve a secure connection between the first mounting frame 20 and the second mounting frame 50.

[0038] It should be noted that the installation direction along the top cover 10, the first mounting bracket 20, the screening component 40 and the second mounting bracket 50 is the axial direction of the screening machine, and the direction perpendicular to the above axial direction is the radial direction of the screening machine.

[0039] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the screening assembly 40 includes a main structure 41, a screen 45, and a support structure 46. The main structure 41 includes a flow cavity. The screen 45 is disposed at the opening of the flow cavity at one end of the main structure 41 near the first mounting frame 20. The support structure 46 is disposed inside the flow cavity and connected to the cavity wall. The screen 45 is positioned relative to the support structure 46 near the first mounting frame 20. The flow cavity extends through the interior of the main structure 41 and has an opening at each end for material to pass through. Specifically, the screen 45 is located at the opening of the flow cavity at one end of the main structure 41 near the first mounting frame 20. The support structure 46, connected to the cavity wall, is located below the screen 45, providing stable support for the screen 45 and reducing the possibility of screen deformation. This allows the support structure to work with the screen 45 to achieve stable screening.

[0040] Specifically, such as Figure 2 As shown, the main structure 41 includes a main body section 42 and a radial extension section 43. The radial extension section 43 is located at one axial end of the main body section 42 and at one end of the main structure 41 near the first mounting bracket 20. The radial extension section 43 extends outward along the radial direction of the main body section 42. A first annular section 31 is fitted onto the radial extension section 43, and a second annular section 32 is fitted onto the main body section 42.

[0041] Along the axial direction of the screening machine, the main structure 41 of the screening assembly 40 sequentially includes a radially extending section 43 and a main body section 42. After the sealing ring 30 is installed on the main body structure 41, the first annular section 31 of the sealing ring 30 surrounds the outer periphery of the radially extending section 43, and the second annular section 32 surrounds the outer periphery of the main body section 42, effectively protecting the outer wall of the main body structure 41. The first annular section 31 is closer to the first mounting bracket 20 than the second annular section 32. The radially extending section 43 extends radially outward along the main body section 42. The first annular section 31 conforms to protect the radially extending section 43 with its larger outer diameter, providing a tighter seal and effectively preventing material leakage from the gap between the screening assembly 40 and the first mounting bracket 20. The second annular section 32 conforms to protect the main body section 42 with its smaller outer diameter, effectively avoiding collisions during the assembly and disassembly of the screening assembly 40, thereby reducing the entry of magnetic substances generated by collisions into the material and ensuring the consistency of material quality.

[0042] Specifically, such as Figure 3As shown, the outer surface of the radial extension 43 includes a first surface 431, a transition surface 432, and a second surface 433 connected in sequence, and the first annular segment 31 is fitted and covers the first surface 431, the transition surface 432, and the second surface 433. Along the axial direction of the screening machine, the outer surface of the radial extension 43 is composed of the first surface 431, the transition surface 432, and the second surface 433, with one end of the second surface 433 connected to the end of the main body segment 42 near the first mounting bracket 20. The first annular segment 31 covers the above three surfaces, enabling the first annular segment 31 to form a continuous sealing ring on the outer surface of the radial extension 43, significantly enhancing the sealing effect.

[0043] Optionally, by changing the outer extension of the radial extension 43, the design of different screening components 40 can be adapted to ensure the fit between the sealing ring 30 and the screening component 40, and solve the sealing and buffering problems under special screening requirements.

[0044] Furthermore, the outer diameter of the main body section 42 is smaller than the inner diameter of the second mounting bracket 50. For example... Figure 4 As shown, when the screening machine starts working, the radially extended section 43 is partially mounted on the second mounting frame 50 so that the main body section 42 is located within the second mounting frame 50. Along the radial direction of the screening machine, the second annular section 32 is located between the main body section 42 and the second mounting frame 50. That is, the gap between the outer wall of the second annular section 32 and the inner wall of the second mounting frame 50 is at least greater than 0 mm, so that even if accidental displacement or shaking occurs during operation, the main body section 42 can be buffered by the second annular section 32, avoiding a hard collision with the second mounting frame 50, thereby reducing the magnetic material generated by the collision.

[0045] Optionally, by adjusting the shape and size of the second annular segment 32, it is possible to adapt to the structure and screening requirements of different screening machines. For example, as Figure 4 In the illustrated embodiment, the end of the second annular segment 32 near the second mounting bracket 50 is flush with the end of the main body segment 42 near the second mounting bracket 50; that is, the end of the second annular segment 32 and the end of the main body segment 42 near the second mounting bracket 50 are flush. For example, along the axial direction of the screening machine, the axial height of the second annular segment 32 is greater than the axial height of the main body segment 42. In other words, appropriately setting the axial height of the second annular segment 32 can prevent damage caused by exposure of the outer wall of the main body segment 42, and will not obstruct the flow of qualified particle size material from the main structure 41.

[0046] like Figure 6 and Figure 7As shown, the support structure 46 includes a support ring 461 and at least two support arms 462. The two ends of each support arm 462 are connected to the support ring 461 and the cavity wall of the flow chamber, respectively. At least two support arms 462 are spaced apart circumferentially along the flow chamber to form a flow channel between adjacent support arms 462. The screen 45 is in direct contact with the support ring 461 and support arms 462 below, thus ensuring the stability of the screening process. Specifically, the two ends of each support arm 462 are firmly connected to the support ring 461 and the cavity wall of the flow chamber, respectively. Multiple support arms 462 are spaced apart circumferentially along the radial direction of the screen, meaning that the interval between the inner ring of the support ring 461 and the support arms 462 together form a flow channel, ensuring smooth flow of material inside the screen. Furthermore, the support ring 461 and support arms 462 extend a certain thickness along the axial direction of the screen, providing sufficient support for the screen 45.

[0047] Optionally, the number of screening components 40 can be one, two, three or more. If the number of screening components 40 is multiple, the screening components 40 are stacked.

[0048] Alternatively, depending on the vibration mode, the screening machine can be a straight-discharge vibrating screen, a circular vibrating screen, or other vibrating screens.

[0049] Optionally, the top cover 10 of the screening machine is provided with a feed inlet 11 and an observation port 12. After the material is fed into the screening machine through the feed inlet 11, it is filtered by the screen 45 after passing through the first mounting frame 20. The operator can observe the screening progress of the material through the observation port 12, thereby controlling the feeding speed of the material. Large particles cannot pass through the screen 45 and will be discharged directly from the slag discharge pipe 21 connected to the first mounting frame 20. Qualified particles fall through the screen 45 and into the second mounting frame 50. The vibration mechanism 60 drives the qualified particles to be discharged from the discharge pipe 51 connected to the second mounting frame 50.

[0050] Optionally, the second mounting bracket 50 is also equipped with an ultrasonic kit 52, which can transmit sound waves through the waveguide rod 521 of the ultrasonic kit 52 to vibrate the accumulated material on the screen 45, thereby improving the screening efficiency.

[0051] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0052] In this application, the vibration mechanism 60 of the screening machine drives the top cover 10, the first mounting frame 20, the screening component 40, and the second mounting frame 50 to vibrate synchronously. This causes the material to pass through the screening component 40 between the first mounting frame 20 and the second mounting frame 50, separating the material into large particles and qualified particles. This effectively achieves the screening of materials by the screening machine, thereby ensuring the continuity and integrity of the screening operation. The screening component 40 is equipped with a circumferential sealing ring 30. The inner wall of the sealing ring 30 is fixedly fitted to the outer wall of the screening component 40, effectively preventing damage to the outer wall of the screening component 40 from hard collisions during screen replacement 45, and thus preventing magnetic substances generated by the collision from mixing into the material. Specifically, the sealing ring 30 is divided into a first annular segment 31 and a second annular segment 32 connected to each other. At the same time, the outer diameter of the first annular segment 31 is larger than the outer diameter of the second annular segment 32. This arrangement helps to form an adaptive sealing effect in different parts of the screening assembly 40. Even under the high-frequency vibration of the vibration mechanism 60, the sealing ring 30 can maintain a stable sealing state, reducing sealing failure and material leakage caused by vibration.
