When producing granular activated carbon, a screening cylinder is usually used for screening. The screening cylinder is rotated by a driving motor to screen out the required size. However, when activated carbon particles enter the screening cylinder, they are likely to fall into the bottom of the screening cylinder in a pile, and the passing property of the activated carbon is affected due to the extrusion effect, that is, it affects the passing of activated carbon particles through the sieve holes of the screening cylinder, thereby affecting the screening effect. Content of the Utility Model

[0024] Refer to the attached Figures 1-8, an activated carbon screening device, comprising a fixed cylinder 1, a driving motor 2, a feeding mechanism 3, a screening mechanism 4 and an adjusting mechanism 5. The fixed cylinder 1 is arranged horizontally, and a first discharge port 6 is formed in the lower cylinder wall of the fixed cylinder 1. The first discharge port 6 is arranged along the length direction. A driving motor 2 is fixed at one end of the fixed cylinder 1. The screening mechanism 4 is located inside the fixed cylinder 1. Two first brackets 7 are fixed inside the screening mechanism 4. A driving shaft 8 is fixedly connected to the centers of the two first brackets 7. One end of the driving shaft 8 sequentially passes through the screening mechanism 4 and the fixed cylinder 1 and is connected to the output end of the driving motor 2. A second bracket 9 is fixed on the inner wall of the fixed cylinder 1 on the side far from the driving motor 2. The other end of the driving shaft 8 passes through the screening mechanism 4 and is connected to the second bracket 9 through a bearing. The feeding mechanism 3 is arranged on the fixed cylinder 1, and the discharge end of the feeding mechanism 3 extends into the screening mechanism 4. An adjustable adjusting mechanism 5 is arranged on the inner wall of the screening mechanism 4. One side of the adjusting mechanism 5 adjacent to the inner wall of the screening mechanism 4 has a predetermined gap, and this predetermined gap is a through hole to facilitate the passage of activated carbon particles. The adjusting mechanism 5 is configured to cause the material to roll down along the inner wall of the screening mechanism 4 when it rises to a predetermined height. The activated carbon particles are lifted to a predetermined height by the adjusting mechanism 5. That is, when the adjusting mechanism 5 at the bottom rotates and rises, the activated carbon particles are lifted to a predetermined height. During the lifting process, the activated carbon particles roll down along the inner wall of the screening mechanism 4 through the through hole, so that the activated carbon particles are screened not only at the bottom of the screening mechanism during the screening process, but also during the rolling process, avoiding the accumulation and extrusion of activated carbon particles during the screening process, which affects the screening effect, and also increasing the contact area and improving the passability. And, due to the movable connection of the adjusting mechanism 5, the predetermined gap between the other adjusting mechanism 5 and the inner wall of the screening mechanism 4 is changed, that is, the size of the through hole is changed, thereby avoiding jamming.

[0025] Specifically, the screening mechanism 4 includes a screening cylinder 401 with openings at both ends. Annular baffles 402 are fixed at both ends of the screening cylinder 401. There is a predetermined distance between the annular baffles 402 and the adjacent end of the fixed cylinder 1. The feeding mechanism 3 is located between the annular baffle 402 and the end face of the fixed cylinder 1. The first bracket 7 is fixed on the inner wall of the screening cylinder 401.

[0026] In this embodiment, the adjusting mechanism 5 includes a sliding groove 501 which is uniformly arranged inside the two annular baffles 402, and the sliding grooves 501 of the two annular baffles 402 are symmetric with each other. A first baffle 502 is slidably connected between the two symmetrically arranged sliding grooves 501. One side of the first baffle 502 adjacent to the inner wall of the screening cylinder 401 has a predetermined gap with the inner wall of the screening cylinder 401. The direction of the sliding groove 501 has a predetermined angle with the radial direction of the annular baffle 402, so that the first baffle 502 and the inner wall of the screening cylinder 401 form a structure with a V-shaped groove to facilitate the lifting of materials. During use, the distance between the first baffle 502 at the bottom and the inner wall of the screening cylinder 401 is the smallest. The V-shaped groove structure formed by the first baffle 502 and the inner wall of the screening cylinder 401 can lift the materials to a predetermined height. During the lifting process, the materials located in the V-shaped groove structure uniformly roll through the through holes onto the wall of the screening cylinder 401, thereby increasing the contact area between the activated carbon particles and the screening cylinder, and also avoiding accumulation and extrusion, thus improving the passing performance and screening effect. The first baffle 502 on the other side slides due to the action of gravity, increasing the distance between the first baffle 502 and the inner wall of the screening cylinder 401 and avoiding jamming.

[0027] In this embodiment, the adjusting mechanism 5 includes a sector-shaped groove 503 which is circumferentially and uniformly arranged inside the two annular baffles 402. The sector-shaped groove 503 opens towards the fixed cylinder 1. The sector-shaped grooves 503 of the two annular baffles 402 are symmetric with each other. A second baffle 504 is rotatably connected between the two symmetrically arranged sector-shaped grooves 503. The second baffle 504 has a predetermined gap with the inner wall of the screening cylinder 401, and the second baffle 504 can rotate a predetermined angle within the sector-shaped groove 503. Similarly, through the swinging action of the second baffle 504, the lifting of materials is realized, and during the lifting process, the materials roll onto the inner wall of the screening cylinder 401 through the gap between the second baffle 504 and the inner wall of the screening cylinder 401, improving the contact area and passing performance. The swinging of the second baffle 504 on the other side increases the gap between the second baffle 504 and the inner wall of the screening cylinder 401, avoiding jamming.

[0028] Among them, the feeding mechanism 3 includes a feeding hopper 301 and a feeding pipe 302. The feeding hopper 301 is fixed at the top of one end of the fixed cylinder 1 and is adjacent to the driving motor 2. The feeding pipe 302 is located between the annular baffle 402 and the end face of the fixed cylinder 1, is connected to the feeding hopper 301 at the upper end, and extends to the inside of the screening cylinder 401 through the annular opening of the annular baffle 402 at the lower end.

[0029] Among them, the lower end of the fixed cylinder 1 is connected to a support seat 10. The upper end face of the support seat 10 has a gap with the fixed cylinder 1 and has an arc-shaped guiding surface to facilitate the discharge of the screened activated carbon particles.

[0030] In this embodiment, in order to achieve the effect of hierarchical screening, a plurality of partition plates 11 are provided on the arc-shaped diversion surface. The screen holes of the screening cylinder 401 gradually increase in the direction of the second support 9, and a plurality of second discharge ports 12 are annularly arranged on the annular baffle 402 adjacent to the second support 9. In order to facilitate the rolling of the activated carbon in a predetermined direction, the screening cylinder 401 is arranged to incline downward in the direction of the second support 9.

[0031] 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 within the protection scope of the present invention.
