[0022] S4. After the screening is completed, adjust the control panel so that the electric telescopic rod is adjusted to the longest state, start the cylinder, push the rod to pull the moving block, so that the moving block moves toward the cylinder, and the semicircular gear rotates to rotate the first fixed rod. After the movable plate and the storage box are rotated to the appropriate position, close the cylinder, and the activated carbon in the first sieve and the second sieve will roll into the storage box, and the operator will collect the activated carbon in the storage box and the pull-out plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0045] An activated carbon screening method with classification function comprises the following steps:

[0046] S1. Place the activated carbon to be treated above the first screen 57, and adjust the control panel 11 so that the electric telescopic rod 9 is adjusted to the shortest state, so that the distance between the first partition 2 and the second partition 3 is shortened;

[0047] S2, start the motors installed in the middle of the moving plates 44 on both sides of the first screen 57. Since the long rods 410 are installed in the middle of the two motors, the long rods 410 rotate to drive the second rotating roller to rotate. A belt is installed between the first rotating roller 49 and the second rotating roller.

At the same time, when the motor is started, the long rod 410 rotates to drive the screw 54 to rotate, and the two push plates 55 start to move, so that the activated carbon is spread on the first screen 57, further accelerating the screening speed.

[0048] S3, by adjusting the control panel 11, after starting the motor installed in the middle of the moving plate 44 on both sides of the second screen 58, the long rod 410 in the middle of the motor rotates to drive the second rotating roller to rotate, so that the first rotating roller 49 rotates to drive the arc plate 48 to rotate, and the moving plate 44 moves up and down, so that the screen frame 51 vibrates up and down, and the activated carbon with the smallest particle size is sieved from the second screen 58 to the top of the pull-out plate 7 in the middle of the cabinet 1;

[0049] S4. After the screening is completed, the control panel 11 is adjusted so that the electric telescopic rod 9 is adjusted to the longest state, the cylinder 62 is started, and the push rod 63 pulls the moving block 64 so that the moving block 64 moves toward the cylinder 62. The semicircular gear 65 rotates to rotate the first fixed rod. After the movable plate 41 and the storage box 66 are rotated to the appropriate positions, the cylinder 62 is closed, and the activated carbon in the first sieve 57 and the second sieve 58 will roll into the storage box 66, and the operator will collect the activated carbon in the storage box 66 and the pull-out plate 7.

9. The activated carbon screening device with classification function according to claim 1, characterized in that: The cabinet body (1) is provided with a cabinet panel (10) mounted on all four sides thereof by means of bolts, and the cabinet panel (10) is provided with a control panel (11) mounted on the outside thereof by means of bolts, and the control panel (11) is electrically connected to the motor, the cylinder (62) and the electric telescopic rod (9).

10. A method for screening activated carbon with classification function, characterized in that: The activated carbon screening method comprises an activated carbon screening device with a classification function as claimed in any one of claims 1 to 9, comprising the following steps: S1, placing the activated carbon to be treated above the first screen (57), and adjusting the control panel (11) so that the electric telescopic rod (9) is adjusted to the shortest state, so that the distance between the first partition (2) and the second partition (3) is shortened; S2, start the motors installed in the middle of the moving plates (44) on both sides of the first screen (57). Since long rods (410) are installed in the middle of the two motors, the long rods (410) rotate to drive the second rotating roller to rotate. A belt is installed between the first rotating roller (49) and the second rotating roller. When the second rotating roller rotates, the first rotating roller (49) rotates accordingly, so that the rotating rod (47) installed in the middle of the first rotating roller (49) rotates to drive the arc plate (48) to rotate. When the arc plate (48) rotates to the top of the movable plate (41), the moving plate (44) moves up, so that the first spring (45) installed at the top of the moving plate (44) presses The movable plate (44) is compressed, and the second spring (46) installed at the bottom end of the movable plate (44) is stretched. When the curved plate (48) is away from the movable plate (41), the elastic force generated by the first spring (45) and the second spring (46) causes the movable plate (44) to move downward. As the curved plate (48) rotates continuously, the screen frame (51) vibrates up and down, and the activated carbon with smaller particle size is sieved from the first screen (57) to the second screen (58). At the same time, when the motor is started, the long rod (410) rotates to drive the screw (54) to rotate, and the two push plates (55) begin to move, so that the activated carbon is spread on the first screen (57), further accelerating the screening speed; S3, by adjusting the control panel (11), the motor installed in the middle of the movable plate (44) on both sides of the second screen (58) is started, and the long rod (410) in the middle of the motor rotates to drive the second rotating roller to rotate, so that the first rotating roller (49) rotates to drive the arc plate (48) to rotate, and the movable plate (44) moves up and down, so that the screen frame (51) vibrates up and down, and the activated carbon with the smallest particle size is sieved from the second screen (58) to the top of the pull-out plate (7) in the middle of the cabinet (1); S4. After the screening is completed, the control panel (11) is adjusted so that the electric telescopic rod (9) is adjusted to the longest state, the cylinder (62) is started, the push rod (63) pulls the moving block (64), so that the moving block (64) moves toward the cylinder (62), the semicircular gear (65) rotates, so that the first fixed rod rotates, the movable plate (41) and the storage box (66) rotate to the appropriate position, and the cylinder (62) is closed. The activated carbon in the first screen (57) and the second screen (58) will roll into the storage box (66), and the operator will collect the activated carbon in the storage box (66) and the pull-out plate (7).
