Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 3 The utility model proposes an activated carbon screening device, including a shell 1, the shell 1 is provided with a discharge port 11, a discharge plate 4 is provided below the discharge port 11, a feed hopper 3 is fixedly connected to the upper end of the shell 1, a door body 2 is hinged on the side wall of the shell 1, and a screening mechanism 5 is provided on the shell 1.

[0026] In the embodiment of the utility model, in order to be able to screen the activated carbon, specifically, the screening mechanism 5 includes a screen frame 50, the screen frame 50 is arranged directly below the feed hopper 3, a motor 51, the motor 51 is fixedly connected to the outer wall of the shell 1, and a reduction box 52, the reduction box 52 is drivingly connected to the motor 51, the output shaft of the reduction box 52 passes through the shell 1 and is rotatably connected to the shell 1, the output shaft of the reduction box 52 is fixedly connected with a rotating shaft 53, the rotating shaft 53 is rotatably connected to the shell 1, the rotating shaft 53 passes through the cam 54 and is fixedly connected to the cam 54, the outer wall of the screen frame 50 is fixedly connected with a protrusion 2 502, the outer wall of one side of the screen frame 50 is fixedly connected with a protrusion 1 501, the outer wall of the other side of the screen frame 50 is fixedly connected with a spring 2 503, the end of the spring 2 503 away from the screen frame 50 is fixedly connected to the inner wall of the shell 1, the inner wall of the shell 1 is fixedly connected with a cross bar 12, the cross bar 12 is provided with a sliding groove 13, and the sliding groove 13 is slidably connected to the screen frame 50;

[0027] like Figure 2As shown, when the motor 51 is started, the transmission of the reduction box 52 causes the rotating shaft 53 to drive the cam 54 to rotate synchronously. During the rotation of the cam 54, the cam 54 first squeezes the protrusion 501 to make the screen frame 50 slide in the sliding groove 13, and the spring 2 503 undergoes elastic deformation. When the force of the cam 54 on the protrusion 501 disappears, the screen frame 50 will return to its original position under the elastic force of the spring 2 503. At this time, the design can make the screen frame 50 reciprocate through the cooperation between the cam 54 and the protrusion 501, thereby improving the screening efficiency of activated carbon.

[0028] Furthermore, a fixing block 14 is fixedly connected to the inner wall of the housing 1, the fixing block 14 is penetrated by a slide rod 15 and is slidably connected to the slide rod 15, one end of a spring 16 is fixedly connected to the outer wall of the slide rod 15, the other end of the spring 16 is fixedly connected to the outer wall of the fixing block 14, and a hammer head 17 is fixedly connected to one end of the slide rod 15 close to the screen frame 50;

[0029] like Figure 3 As shown, during the reciprocating motion of the screen frame 50, the protrusion 2 502 will squeeze the hammer head 17, so that the slide rod 15 drives the hammer head 17 to move upward, and at the same time, the spring 16 undergoes elastic deformation. It should be noted that under normal conditions, the hammer head 17 is in contact with the outer wall of the screen frame 50. At the same time, in this state, the spring 16 is in an elastic deformation state. When the protrusion 2 502 is separated from the hammer head 17, the hammer head 17 will hit the screen frame 50 under the action of the elastic force of the spring 16, causing the screen frame 50 to vibrate, thereby improving the efficiency of the screen frame 50 in screening activated carbon.

[0030] In the utility model, when in use, the activated carbon is first poured into the shell 1 through the feed hopper 3, and the motor 51 is started. At this time, the transmission of the reduction box 52 causes the rotating shaft 53 to drive the cam 54 to rotate synchronously. During the rotation of the cam 54, the cam 54 first squeezes the protrusion 501, and then the cooperation between the cam 54 and the protrusion 501 can make the screen frame 50 reciprocate to speed up the screening of the activated carbon. During this process, the protrusion 502 will squeeze the hammer head 17, so that the slide bar 15 drives the hammer head 17 to move upward. When the protrusion 502 is separated from the hammer head 17, the hammer head 17 will hit the screen frame 50 under the elastic force of the spring 16, causing the screen frame 50 to vibrate, thereby improving the efficiency of the screen frame 50 in screening activated carbon. Finally, the door body 2 is opened to take out the activated carbon in the screen frame 50.
