Description

Technical Field

[0001] This application relates to the technical field of artificial graphite processing, and particularly relates to a screening device for the production of artificial graphite particles. Background Art

[0002] In the production process of artificial graphite particles, the screening link is a crucial step. Through screening, graphite particles of different particle sizes can be effectively classified to ensure that the quality of the final product meets the standard requirements.

[0003] In practical applications, in the screening process of existing graphite screening equipment, due to the special physical and chemical properties of graphite particles, such as high hardness and certain adhesiveness, they are prone to accumulate and block on the material-passing net during the screening process. Especially when the particle size distribution is uneven or the screening time is long, this blockage phenomenon is particularly obvious. When graphite particles block on the material-passing net, it will seriously affect the screening efficiency, making the screening process slow and unstable, and may even damage the screening equipment.

[0004] To address this problem, traditional screening equipment often adopts the method of vibrating screening. By vibrating, it can prompt the graphite particles to move on the sieve mesh, thereby reducing the blockage phenomenon. However, although vibrating screening can alleviate the blockage problem to a certain extent, it also has disadvantages such as high energy consumption, high noise, and high maintenance costs. In addition, for some graphite particles with specific sizes and shapes, the effect of vibrating screening is not ideal, and blockage still occurs.

[0005] In view of the above problems, a screening device for the production of artificial graphite particles is now designed. Utility Model Content

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] An embodiment of the present application provides a screening device for the production of artificial graphite particles, which can solve the problem that existing graphite screening equipment in the related art is prone to form accumulation and blockage on the material passing net during the screening process.

[0037] Please refer to Figures 1 - 3 , a screening device for the production of artificial graphite particles includes; a frame body 1, a screening box 2 arranged obliquely on the frame body 1, a filter screen 3, a cleaning mechanism 4 and a feeding roller 5. The inside of the screening box 2 has a chamber for screening graphite particles; the filter screen 3 is arranged inside the screening box 2 along the length direction of the screening box 2; a feeding hopper 8 is provided at the top of the upper end of the screening box 2 inclined upward, and a material distribution port 7 is provided at the bottom and the lower end of the screening box 2 inclined downward; the cleaning mechanism 4 is arranged inside the screening box 2 and is used for stirring the graphite particles above the filter screen 3; the feeding roller 5 is arranged inside the feeding hopper 8 and is used for guiding the graphite particles inside the feeding hopper 8 to uniformly enter the inside of the screening box 2.

[0038] The graphite particles enter the screening system through the feeding hopper 8. The feeding roller 5 can guide the graphite particles to uniformly and stably enter the inside of the screening box 2, which helps to avoid the accumulation and blockage of graphite particles during feeding and improves the screening efficiency.

[0039] The screening box 2 is arranged obliquely and a filter screen 3 is arranged inside. When the graphite particles enter the screening box, they will slide down along the screen surface and are affected by gravity during this process.

[0040] The larger graphite particles cannot pass through the mesh holes of the filter screen 3, so they will slide down along the screen surface and finally be discharged from the material distribution port 7 at the lower end of the screening box 2 inclined downward for subsequent processing.

[0041] The smaller graphite particles can pass through the filter screen 3 and continue to move inside the screening box 2 and are discharged through the material distribution port 7 at the bottom of the screening box 2.

[0042] The cleaning mechanism 4 is arranged inside the screening box 2 and is used for periodically or continuously stirring the graphite particles above the filter screen 3, which helps to prevent the graphite particles from forming accumulation on the screen surface or blocking the mesh holes, and ensures the continuity and high efficiency of the screening process.

[0043] Through the guidance of the feeding roller 5, the graphite particles can uniformly enter the screening box 2, reducing the accumulation and blockage phenomena during feeding, thereby improving the screening efficiency.

[0044] The obliquely arranged screening box 2 and the filter screen 3 enable the graphite particles to be affected by gravity during the sliding process, accelerating the screening process.

[0045] The arrangement of the cleaning mechanism 4 reduces the need for manual cleaning of the screen surface, reduces labor intensity and maintenance costs. At the same time, by preventing the mesh from being blocked, the service life of the screen and the entire screening device is extended.

[0046] Specifically, the screening box 2 in this embodiment includes a box body 21 and a cover plate 22 connected to each other, the bottom of the box body 21 is arranged in a V shape, a feed port connected to the feed hopper 8 is arranged above the cover plate 22, and the filter screen 3 is arranged on the top of the box body 21. The feed port 7 at the bottom is set at the lowest point of the bottom of the box body 21.

[0047] The bottom of the box body 21 is arranged in a V-shape, which is conducive to the graphite particles to naturally slide to both sides during the screening process and gather at the distribution port 7 at the bottom.

[0048] A feed port connected to the feed hopper 8 is provided above the cover plate 22, which is the entrance for graphite particles to enter the screening box 2. The cover plate 22 not only seals and protects the interior of the screening box, but also forms a sealed screening environment together with the box body 21 to reduce dust spillage.

[0049] In one embodiment, the cleaning mechanism 4 includes: a driving member 41 arranged on the cover plate 22; a toggle plate 42 slidably arranged inside the cover plate 22; the driving member 41 is connected to the toggle plate 42 and is used to drive the toggle plate 42 to move along the length of the filter screen 3; a plurality of bristles in contact with the filter screen 3 are arranged at the bottom of the toggle plate 42.

[0050] When the driving member 41 is activated, it drives the toggle plate 42 to reciprocate along the length direction of the filter screen 3. This movement can be continuous or intermittent, depending on the requirements of the screening process and the control program of the driving member.

[0051] The bottom of the toggle plate 42 is provided with a plurality of bristles that are in close contact with the filter screen 3. These bristles are made of wear-resistant, soft and elastic materials to ensure that they can effectively clean the surface of the filter screen without causing damage to the filter screen. As the toggle plate 42 moves, the bristles will continuously brush the surface of the filter screen 3, cleaning off the graphite particles, impurities or agglomerates attached thereto. These cleaned particles or impurities will fall into the bottom of the screening box 2 or other collection devices for subsequent processing.

[0052] Regular cleaning of the cleaning mechanism 4 effectively prevents clogging of the filter screen 3, ensuring the continuity and efficiency of the screening process. When the filter screen remains unobstructed, the graphite particles can pass through the mesh faster, thereby improving the screening efficiency.

[0053] The cleaning mechanism 4 is simple and practical in design and is suitable for the screening of graphite particles of different sizes and shapes. The cleaning effect and screening efficiency can be further optimized by adjusting the working parameters of the driving member 41 such as speed and stroke.

[0054] Furthermore, the driving member 41 includes a housing 411 disposed on the cover plate 22, a driving motor 412 is disposed inside the housing 411, a screw 413 is disposed on the output shaft of the driving motor 412, and a transmission rod 414 is threadedly connected to the screw 413; a through hole connected to each other is provided between the housing 411 and the cover plate 22, and one end of the transmission rod 414 is connected to the toggle plate 42. The screw 413 is arranged along the length of the filter screen 3, and an accordion protective cover is disposed inside the through hole on both sides of the transmission rod 414.

[0055] The driving motor 1 412 is used as a power source to drive the screw rod 413 to rotate through its output shaft. The screw rod 413 is arranged inside the housing 411 along the length direction of the filter screen 3, and its surface has threads. The transmission rod 414 is connected to the screw rod 413 through threads, so when the screw rod rotates, the transmission rod 414 will move linearly along the length direction of the screw rod. One end of the transmission rod 414 is connected to the toggle plate 42, so when the transmission rod moves under the drive of the screw rod 413, it will drive the toggle plate 42 to move along the length direction of the filter screen 3.

[0056] Interconnected through holes are provided between the housing 411 and the cover plate 22 so that the transmission rod 414 can pass through and connect to the toggle plate 42. An accordion protective cover is provided inside the through hole, which is located on both sides of the transmission rod 414 and expands and contracts with the movement of the transmission rod. The main function of the accordion protective cover is to prevent dust, impurities, etc. from entering the housing 411 and protect the drive motor 412 and the screw rod 413 from pollution and damage.

[0057] Through the precise cooperation of the driving motor 412 and the screw rod 413, the position of the transmission rod 414 and the toggle plate 42 can be precisely controlled. This precise control helps to ensure that the cleaning mechanism 4 can work according to the predetermined trajectory and speed during the screening process, thereby improving the cleaning effect and screening efficiency.

[0058] The threaded connection between the screw rod 413 and the transmission rod 414 is self-locking, which can prevent the transmission rod from slipping or falling off during movement to a certain extent. At the same time, the setting of the accordion protective cover further enhances the stability and reliability of the structure and reduces failures and damages caused by external factors.

[0059] Specifically, a slide rail 6 is disposed inside the cover plate 22 and arranged along the length direction of the filter screen 3 , and the other end of the toggle plate 42 away from the transmission rod 414 is slidably matched with the slide rail 6 .

[0060] The slide rail 6 is precisely installed inside the cover plate 22, and its length direction is consistent with the length direction of the filter screen 3. The slide rail 6 is usually made of wear-resistant and corrosion-resistant materials.

[0061] One end of the toggle plate 42 away from the transmission rod 414 is provided with sliding components such as a slide block, a slide groove, etc. that match the slide rail 6. These sliding components can be closely embedded in the slide rail 6 and slide smoothly on the slide rail as the transmission rod 414 pushes.

[0062] The sliding cooperation between the slide rail 6 and the toggle plate 42 can ensure the stability and linearity of the toggle plate during movement, thereby reducing the risk of uneven cleaning or damage to the filter screen due to deviation or shaking of the toggle plate.

[0063] In one embodiment, the material distribution roller 5 includes a rotating shaft 51 rotatably disposed inside the feed hopper 8, a roller 52 is disposed on the rotating shaft 51, a material distribution plate 53 is disposed in an annular shape on the roller 52, and the roller 52 is hollow inside.

[0064] The roller 52 is fixedly mounted on the rotating shaft 51 and rotates with the rotating shaft. The diameter and length of the roller 52 are designed according to the size of the feed hopper 8 and the characteristics of the material to ensure that the material can fully contact the distribution plate 53 and be evenly distributed.

[0065] The interior of the drum 52 is designed to be a hollow structure, which helps to reduce the overall weight of the drum, reduce the load, and may provide a certain heat insulation or sound insulation effect.

[0066] The main function of the dividing plate 53 is to divide and rearrange the materials entering the feed hopper 8 to ensure that the materials can enter the subsequent screening or processing process evenly and orderly.

[0067] It should be noted that there is a gap between the dividing plate 53 and the feed hopper 8, and the gap satisfies the flow of graphite particles.

[0068] Furthermore, in this embodiment, the material distribution roller 5 also includes a reducer 54 arranged on the feed hopper 8, and a driving motor 2 55 is arranged on the reducer 54. The output shaft of the reducer 54 is connected to either end of the rotating shaft 51, and the output shaft of the driving motor 2 55 is connected to the input shaft of the reducer 54.

[0069] The drive motor 2 55 provides power to the reducer 54 through the rotation of the output shaft. The drive motor 2 55 usually has an adjustable speed and power to meet the requirements of different materials and processes. In addition, the drive motor 2 55 can also be connected to a control system to achieve automatic control and remote monitoring.

[0070] The main function of the speed reducer 54 is to reduce the rotational speed of the output shaft of the driving motor II 55 and increase the torque to match the rotational requirements of the rotating shaft 51 and the drum 52. Through the adjustment of the speed reducer 54, it can be ensured that the material distribution drum 5 rotates at an appropriate speed, neither too fast causing the material to not be fully dispersed and distributed, nor too slow affecting the screening or processing efficiency.

[0071] In one embodiment, in order to improve the filtering efficiency, the screening box 2 in this implementation scheme is mounted on the frame body 1 through springs, and a vibration motor is provided on the screening box 2.

[0072] Mounting the screening box 2 on the frame body 1 through springs can enable the screening box 2 to generate a certain degree of vibration under the drive of the vibration motor. This vibration helps to break the adhesion force between the materials, make the materials more loosely distributed on the sieve mesh, increase the contact area and opportunities between the materials and the sieve mesh, thereby improving the screening efficiency.
