Description

Technical Field

[0001] This utility model relates to the field of carbon raw material screening technology, and more specifically, to a carbon block raw material screening device. Background Technology

[0002] Charcoal briquettes, as an important industrial raw material, are widely used in metallurgy, chemical industry, energy and other fields. In the production of charcoal briquettes, raw material screening is one of the key process steps. Its purpose is to separate raw materials of different particle sizes to ensure product quality and production efficiency. Traditional charcoal briquette raw material screening devices usually adopt a fixed screen structure. However, in actual use, screen clogging is prone to occur, especially when the raw material has high moisture content or contains a lot of fine powder. Screening efficiency drops significantly, and may even lead to equipment shutdown for cleaning, seriously affecting production continuity.

[0003] While some existing screening devices employ vibration or tapping mechanisms to reduce screen clogging, these structures are often complex in design, have high maintenance costs, and limited anti-clogging effectiveness. Furthermore, traditional screening devices suffer from insufficient material feeding uniformity, which can easily lead to localized screen overload, further exacerbating clogging and affecting screening efficiency. Therefore, there is a need for a carbon block raw material screening device with a reasonable structure, excellent anti-clogging performance, and the ability to achieve uniform material feeding, in order to improve screening efficiency, reduce maintenance costs, and meet the needs of industrial production.

[0004] Based on this, this utility model discloses a carbon block raw material screening device. Summary of the Invention

[0005] To address the problems mentioned in the background art, where existing screening devices partially employ vibration or tapping mechanisms to reduce screen clogging, but these structures are often complex in design, have high maintenance costs, and limited anti-clogging effects, and where traditional screening devices suffer from insufficient material feeding uniformity, easily leading to localized screen overload and further exacerbating clogging, thus affecting screening efficiency, this utility model provides a carbon block raw material screening device, which includes a screening tank, a tank cover at the top of the screening tank, a screening screen inside the screening tank, anti-clogging components on both sides of the screening screen, and a uniform material feeding component at the top of the tank cover; The anti-clogging component includes two hollow columns, each of which is fixedly connected to both sides of the upper part of the screening tank. A return spring is fixedly connected to the inner cavity of the hollow column, and a pressing rod is fixedly connected to the upper part of the return spring. The surface of the pressing rod is slidably connected to the inner wall of the hollow column, and the hollow column limits the pressing rod. A drive block is fixedly connected to the upper part of each pressing rod.

[0006] As a further improvement to this technical solution, grooves are provided on both sides of the screening tank at positions corresponding to the drive blocks. Each drive block passes through the grooves, and the opposite side of each drive block is fixedly connected to both sides of the screening screen. Hollow boxes are fixedly connected to the opposite side of the grooves on the screening tank, and baffles are slidably connected to the opposite side of each hollow box. Each baffle is fixedly connected to the upper and lower parts of the drive block.

[0007] As a further improvement to this technical solution, a cam is provided on the upper part of the drive block, and a rotating rod is fixedly connected to the inner cavity of each cam. The end of each rotating rod meshes with a transmission component through a helical gear pair, and a drive shaft is meshed with the opposite side of each transmission component.

[0008] As a further improvement to this technical solution, a synchronous pulley A is fixedly connected to one side of the drive shaft surface, a synchronous belt is sleeved on the surface of the synchronous pulley A, a synchronous pulley B is driven to one end of the inner cavity of the synchronous belt, a drive motor is provided on one side of the synchronous pulley B, and the output shaft of the drive motor is fixedly connected to the synchronous pulley B.

[0009] As a further improvement to this technical solution, the uniform feeding assembly includes a feeding pipe, which is movably connected to the inside of the can lid via a bearing. A worm gear is fixedly connected to the surface of the feeding pipe, and a worm is meshed with one end of the worm gear. The worm is fixedly connected to the drive shaft.

[0010] As a further improvement to this technical solution, the upper part of the discharge pipe is connected to a feed hopper via a rotary joint.

[0011] Compared with existing technologies, the beneficial effects of this utility model are: 1. In this charcoal raw material screening device, the anti-clogging component design enables automatic high-frequency vibration of the screening screen. When the cam rotates, it periodically presses down the drive block to make the screening screen move up and down reciprocally, effectively shaking off the accumulated charcoal raw material, preventing screen blockage, improving screening efficiency, and reducing the frequency of manual cleaning and maintenance costs.

[0012] 2. In this charcoal block raw material screening device, the uniform feeding component design achieves uniform dispersion of charcoal block raw materials. The drive shaft drives the worm gear to rotate, causing the feeding pipe to rotate slowly, ensuring that the raw materials are evenly spread on the screening screen, avoiding local accumulation that could lead to uneven screening or overload, improving screening quality, reducing equipment wear, and extending service life.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Therefore, this utility model provides a carbon block raw material screening device, see [link to relevant documentation]. Figures 1 to 6 As shown, it includes a screening tank 1, a tank cover 2 is provided on the upper part of the screening tank 1, a screening screen 3 is provided in the inner cavity of the screening tank 1, anti-clogging components are provided on both sides of the screening screen 3, and a uniform feeding component is provided on the upper part of the tank cover 2. The anti-clogging component includes two hollow columns 4, each fixedly connected to the upper sides of the screening tank 1. A return spring 5 is fixedly connected to the inner cavity of each hollow column 4, and a pressing rod 6 is fixedly connected to the upper part of the return spring 5. The surface of the pressing rod 6 is slidably connected to the inner wall of the hollow column 4, and the hollow column 4 limits the movement of the pressing rod 6. A driving block 7 is fixedly connected to the upper part of each pressing rod 6. Grooves are provided on both sides of the screening tank 1 at positions corresponding to the driving blocks 7, and each driving block 7 passes through the groove. One side of each driving block 7 is fixedly connected to both sides of the screening screen 3. Hollow boxes 8 are fixedly connected to the opposite sides of the grooves on the screening tank 1. A baffle plate 9 is slidably connected to one side of the drive block 7. Each baffle plate 9 is fixedly connected to the upper and lower parts of the drive block 7. A cam 10 is provided on the upper part of the drive block 7. A rotating rod 11 is fixedly connected to the inner cavity of each cam 10. The end of each rotating rod 11 meshes with the transmission component 12 through a helical gear pair. A drive shaft 13 is meshed with the opposite side of each transmission component 12. A synchronous pulley A14 is fixedly connected to one side of the surface of the drive shaft 13. A synchronous belt 15 is sleeved on the surface of the synchronous pulley A14. A synchronous pulley B16 is drivenly connected to one end of the inner cavity of the synchronous belt 15. A drive motor 17 is provided on one side of the synchronous pulley B16. The output shaft of the drive motor 17 is fixedly connected to the synchronous pulley B16.

[0017] During operation, the drive motor 17 starts, driving the synchronous pulley B16 to rotate. Through the transmission of the synchronous belt 15, the synchronous pulley A14 and the drive shaft 13 rotate synchronously. The drive shaft 13 drives the rotating rods 11 on both sides to rotate through the transmission component 12, causing the cam 10 to rotate accordingly. When the cam 10 rotates, its protruding part periodically presses the drive block 7 downward, causing the pressing rod 6 to slide downward in the hollow column 4 and compress the return spring 5. When the protruding part of the cam 10 disengages from the drive block 7, the return spring 5 rebounds, pushing the pressing rod 6 and the drive block 7 to return upward. Since the drive block 7 is fixedly connected to the screening screen 3, the screening screen 3 vibrates up and down, continuously shaking off the carbon blocks accumulated on the screen, effectively preventing blockage. The baffle plate 9 moves up and down with the drive block 7, always covering the groove on the screening tank 1, preventing the raw material from entering the hollow box 8 or the hollow column 4, ensuring stable operation of the equipment.

[0018] Further, see Figures 1 to 5 As shown, the uniform feeding assembly includes a feeding pipe 18, which is movably connected to the inside of the can cover 2 via a bearing. A worm gear 19 is fixedly connected to the surface of the feeding pipe 18, and a worm 20 is meshed at one end of the worm gear 19. The worm 20 is fixedly connected to the drive shaft 13. The upper part of the feeding pipe 18 is connected to a feed hopper 21 via a rotary joint.

[0019] During operation, the drive shaft 13 drives the worm gear 20 to rotate, and the worm gear 20 meshes with the worm wheel 19, causing the feed pipe 18 to rotate slowly inside the can cover 2. The charcoal raw material enters the feed pipe 18 from the feed hopper 21 and is evenly dispersed onto the screening screen 3 under the action of rotation, avoiding local accumulation and improving screening efficiency.

[0020] In summary, this approach effectively addresses the problems of existing screening devices, which, while employing vibration or tapping mechanisms to reduce screen clogging, often suffer from complex designs, high maintenance costs, and limited anti-clogging effectiveness. Furthermore, traditional screening devices often suffer from insufficient material feeding uniformity, leading to localized screen overload, which further exacerbates clogging and affects screening efficiency.
