Description

Technical Field

[0001] The present invention relates to the technical field of screening devices, and particularly to a waste screening and recycling device for carbon material processing. Background Art

[0002] In the production process of carbon products, raw materials need to be processed into different shapes. The cut-off scraps after the finished products can be recycled, crushed and screened again, and a screening device is required during screening.

[0003] Referring to the Chinese invention patent with the publication number: CN 117753655 A and the name: A screening device for carbon product manufacturing. Through the main body, slider, lead screw, and cleaning motor structures provided in this invention, during the operation of the device, the user can drive the cam to rotate synchronously through the rotation of the output shaft of the screening motor, thereby improving the screening effect of the screening plate on carbon manufacturing raw materials. At the same time, the user can drive the two lead screws to rotate synchronously and reversely through the rotation of the output shaft of the lead screw, and use the guiding operation of the material guiding groove to facilitate the user's recycling operation without manual cleaning by the user, improving the practicability of the device.

[0004] However, in the actual use process, the above and similar technical solutions still have some problems: 1. During the shaking screening process, due to the large noise generated by mechanical vibration, it seriously affects the comfort and quality of the working environment and poses a potential threat to the hearing health of the operators; as the key component driving the screening equipment, the motor needs to work continuously for a long time to maintain the stability of screening, resulting in a significant increase in power consumption and an increase in operating costs; the design of using a rectangular screen, although meeting the screening requirements to a certain extent, occupies a large movement space, and when placed horizontally, it is difficult to control the screening speed, affecting the screening efficiency and accuracy; 2. During the screening process, due to the light weight of fine particles, they are easily affected by air flow and suspended in the air to form dust; these dusts not only pollute the working environment, but may also damage the respiratory systems of the operators, and long-term exposure may even cause occupational diseases; 3. As the core component of the screening equipment, the smoothness of the screen directly affects the screening efficiency. Therefore, the screen needs to be regularly dredged to ensure its normal operation. During the dredging process, brushes and scrapers are usually used for cleaning. However, due to the long scraper and the middle part of the screen being easily deformed by external forces during long-term use; the deformation of the screen will lead to a decline in the cleaning effect, affecting the screening accuracy and efficiency.

[0016] Compared with the prior art, the present invention provides a waste screening and recycling device for carbon material processing, which has the following beneficial effects: 1. For the waste screening and recycling device for carbon material processing, the crushed carbon material waste is placed in the feeding hopper. The carbon material waste falls onto the spiral screen bars through the feeding hopper and slides downward along the spiral screen bars under the action of gravity for screening. The fine particles will pass through the screen and fall onto the spiral receiving bars, thus completing the screening purpose.

[0017] 2. For the waste screening and recycling device for carbon material processing, for the fine carbon material waste particles with low quality, start the first fan, so as to form a negative pressure in the mesh cylinder. External gas enters through the air holes, passes between the spiral screen bars and the spiral receiving bars, and then enters the top of the first fan through the holes of the mesh cylinder. The air will carry the fine carbon material waste particles between the spiral screen bars and the spiral receiving bars, so as to extract the particulate dust and discharge it into the interior of the discharge pipe through the first fan. By installing a dust collection bag at the outer end of the discharge pipe, it can be collected, effectively avoiding the particulate dust from diffusing into the air and affecting the health of the staff.

The spiral screen bar is narrow and not easy to sink, and the contact area is large during scraping, so as to ensure the screening efficiency. The filter screen can intercept fine particles. During the screening process, the collection cylinder can be pulled out to observe the size and composition of the fine particles in the filter screen, which is convenient for sampling at any time.

[0032] In the present invention, a second fan 45 is installed below the collecting cylinder 41 on the fixing plate 42. A first spring 47 is installed between the brush 43 and the fixing plate 42.

The inside of the mesh cylinder 29 is communicated with the outside through the through groove and the air duct 44, so as to increase the negative pressure at the bottom end of the filter screen 46 and facilitate the capture of floating dust particles.

[0033] In the present invention, a control component 53 for driving the rotation of the mesh cylinder 29 is connected to the cylinder body 1. The control component 53 includes a first gear 533. The first gear 533 is installed on the outer wall of the mesh cylinder 29. A fixing frame 531 is installed on the cylinder body 1. A motor 532 is installed on the fixing frame 531. A second gear 534 is installed on the output shaft of the motor 532.

[0034] In the present invention, a slide bar 58 is installed on the outer wall of the mesh cylinder 29. A slider 57 is slidably connected to the slide bar 58. A second spring 51 is movably sleeved outside the slide bar 58. A fixed bar 55 is installed on the slider 57. A connecting rod 54 is movably connected between the fixed bar 55 and the scraper 52. A torsion spring 56 is installed between the connecting rod 54 and the scraper 52, so as to ensure that the scraper 52 is in close contact with the surface of the spiral screen bar 26 and ensure the cleaning effect.

[0035] Working principle: Place the crushed carbon material waste in the feed hopper 25. The carbon material waste falls onto the spiral screen bar 26 through the feed hopper 25 and slides downward along the spiral screen bar 26 under the action of gravity. The rubber strip 281 plays a sealing role to prevent fine particles from getting stuck in the gaps at both ends of the spiral screen bar 26, so as to carry out screening. The fine particles will pass through the screen and fall onto the spiral receiving bar 27, slide downward through the spiral receiving bar 27, and are separated through the coarse material hopper 22 and the fine material hopper 23, thus completing the screening purpose. When it is necessary to adjust the screening speed, start the electric push rod 211, so as to pull the telescopic cylinder 212 to slide downward, drive the rotating bar 282 to move through the connecting plate 283 at the top, and then drive the tops of the spiral screen bar 26 and the spiral receiving bar 27 to move downward synchronously. The rotating bar 282 can ensure the smooth connection between the connecting plate 283 and the spiral screen bar 26 and the spiral receiving bar 27, so as to compress the spiral screen bar 26 and the spiral receiving bar 27, change the pitch, the pitch decreases, the slope becomes gentler, thus slowing down the movement speed of the carbon material waste and facilitating the improvement of the screening quality. When the electric push rod 211 extends, the slope becomes steeper, thus increasing the movement speed of the carbon material waste and facilitating the rapid screening of waste with large differences in thickness, so as to improve the screening efficiency. For the fine carbon material waste particles with low mass, start the first fan 33, so as to form a negative pressure in the mesh cylinder 29. External gas enters through the air holes 31, passes through between the spiral screen bar 26 and the spiral receiving bar 27, and then enters the top of the first fan 33 through the holes in the mesh cylinder 29. The air will carry the fine carbon material waste particles between the spiral screen bar 26 and the spiral receiving bar 27, so as to extract the particle dust, discharge it into the interior of the discharge pipe 32 through the first fan 33, and can be collected by installing a dust collection bag at the outer end of the discharge pipe 32, effectively avoiding the particle dust from diffusing into the air and affecting the health of the staff. Start the motor 532. The motor 532 drives the second gear 534 to rotate, thereby driving the first gear 533 to rotate and driving the mesh cylinder 29 to rotate. When the mesh cylinder 29 rotates, its inner side will rub against the brush 43. The first spring 47 pushes the brush 43 to tightly contact the inner wall of the mesh cylinder 29, so that the holes in the mesh cylinder 29 can be dredged, ensuring the efficiency of dust removal. At the same time, when the mesh cylinder 29 rotates, it will drive the slider 57 to rotate synchronously, drive the scraper 52 to rotate through the fixed rod 55 and the connecting rod 54, and the torsion spring 56 pushes the scraper 52 to tightly contact the surface of the spiral screen bar 26, so that the scraper 52 moves upward spirally along the surface of the spiral screen bar 26, thereby pushing and cleaning the particles blocked in the mesh holes of the spiral screen bar 26 to ensure the screening efficiency. When the scraper 52 moves to the top, the drive motor 532 reverses, thereby driving the scraper 52 to move downward and reset, so as to facilitate working again. While the brush 43 is rotating, the second blower 45 works, forming a negative pressure at one end of the brush 43 through the air duct 44 to suck in the fine particles brushed off. Under the action of the filter screen 46, the fine particles are intercepted. During the screening process, the collection cylinder 41 can be pulled out to observe the size and composition of the fine particles in the filter screen 46, which is convenient for sampling at any time.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
