A vibration motor 5 is installed on one side of the bottom end of the screening box 2. When the vibration motor 5 is started, the leg 8 can be conveniently extended and retracted up and down in the sleeve 6, thereby realizing convenient up and down vibration of the device. A screening mesh plate 15 is installed in the middle part of the screening box 2, and two short shafts 16 are symmetrically welded in the middle of the two side walls of the screening mesh plate 15. A rotating motor 9 is fixed on the outside of the screening box 2 opposite to one of the short shafts 16. Two through holes 11 are symmetrically opened on both sides of the screening mesh plate 15 on the screening box 2, and an electric cylinder 4 runs through the through hole 11. When the screening mesh plate 15 needs to be moved after screening When the residual activated carbon on the screen is discharged, it is necessary to first separate the clamping block 10 from the screening mesh plate 15, and then the screening mesh plate 15 is rotated 180° under the action of the rotating motor 9, and the clamping block 10 is again pressed against the side of the screening mesh plate 15, and then the device only needs to continue to vibrate to achieve the discharge of the residual activated carbon in the device. The telescopic part of the electric cylinder 4 is equipped with a clamping block 10 for limiting and clamping the screening mesh plate 15. The electric cylinder 4 drives the clamping block 10 to press against the side of the screening mesh plate 15, which can achieve convenient limiting of the screening mesh plate 15. An elastic film 14 is installed on the side wall where the screening mesh plate 15 contacts the clamping block 10. The elastic film 14 is mainly used to avoid the accumulation of activated carbon on the side of the screening mesh plate 15 during the screening process, so as to facilitate the rotation and discharging of the screening mesh plate 15.

[0032] like Figure 1-Figure 4 As shown, in this embodiment, the rod diameter at the top end of the leg 8 is smaller than the inner hole diameter of the sleeve 6, the spring 12 is welded to the sleeve 6 and the leg 8, the short shaft 16 is rotatably connected to the screening box 2, the rotating motor 9 is connected to the corresponding short shaft 16 through a coupling, the short shaft 16 can realize convenient rotation adjustment of the screening mesh plate 15 relative to the screening box 2, the clamping block 10 is a U-shaped structure, the elastic film 14 is bonded to the screening mesh plate 15, and the cross-section of the outer wall of the screening mesh plate 15 is an arc structure.

[0033] like Figure 1-Figure 4 As shown, in the present embodiment, a support plate 7 is welded on the screening box 2 at the bottom end of the electric cylinder 4, and the support plate 7 is bolted to the electric cylinder 4. The support plate 7 can realize the reliable installation and fixation of the electric cylinder 4. A feeding port 1 is also opened in the middle of the top end of the screening box 2, and a straight-through discharge pipe 13 is welded in the middle of the bottom end of the screening box 2. The activated carbon to be screened can be conveniently added to the screening box 2 through the feeding port 1, and the screened activated carbon will be discharged through the discharge pipe 13 first.

The operation panel 3 can realize the orderly operation of the rotating motor 9 and the electric cylinder 4, so as to realize efficient screening and discharge of the activated carbon.

[0034] The specific implementation process of this embodiment is as follows: when in use, first connect the device to an external power source, and put the activated carbon to be screened into the screening box 2 through the feeding port 1, and then just start the vibration motor 5, and the sleeve 6, the legs 8 and the spring 12 can be used to realize the bottom and top vibration of the screening box 2, so as to realize the screening of the activated carbon. The small particles of activated carbon after screening will be directly discharged through the discharge pipe 13, while the large particles of activated carbon will remain on the screening mesh plate 15. When the residual activated carbon needs to be cleaned, it is firstly discharged through the electric discharge pipe 13. The moving cylinder 4 separates the clamping block 10 from the screening mesh plate 15, and then uses the rotating motor 9 to rotate the screening mesh plate 15 180°, and cooperates with the clamping block 10 to limit the screening mesh plate 15 again, so as to realize the convenient discharge of large particles of activated carbon after screening through vibration again. Because the activated carbon is evenly distributed on the screening mesh plate 15 under the above-mentioned screening and discharging method, the inconvenience caused by the accumulation of large particles of activated carbon to the screening of small particles of activated carbon during the screening process is avoided, so that the device has a higher screening efficiency for activated carbon.
