Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0024] Referring to Figs. 1 to 3 The vibrating screen in the embodiment includes a frame 3, a plurality of support columns 6 fixedly arranged at the bottom of the frame 3, a plurality of screen assemblies 1 detachably arranged inside the frame 3, a clamp assembly 2, a cover plate 4 coveringly arranged at the top of the frame 3, a dust hopper 5 fixedly arranged at the bottom of the frame 3, a discharge assembly 7 fixedly arranged at one end of the screen assembly 1, and a motor 8 fixedly arranged at both sides of the dust hopper 5. The plurality of screen assemblies 1 are arranged at intervals along the height direction of the frame 3. Each screen assembly 1 has one clamp assembly 2 detachably arranged at each side thereof. Each clamp assembly 2 is further detachably connected with the inner wall of the frame 3. The dust hopper 5 is in communication with one screen assembly 1 at the bottom layer. The dust hopper 5 is used for collecting the waste materials left after being screened by the plurality of screen assemblies 1. The cover plate 4 is provided with a feed inlet 41. The cover plate 4 covers the top of one screen assembly 1 at the top layer and the discharge assembly 7, so as to avoid the activated carbon particles from splashing out when the vibrating screen vibrates. The activated carbon particles to be screened can directly fall on the screen assembly 1 at the top layer after being poured into the feed inlet 41. The motor 8 is used for driving the dust hopper 5 and the frame 3 to vibrate, so as to make the activated carbon particles on the screen assembly 1 vibrate to screen the activated carbon of different particle sizes.

[0025] Further, three screen assemblies 1 are arranged in the embodiment. Each screen assembly 1 includes a first screen 11 and a second screen 12. The bottom surface of the first screen 11 is attached to the top surface of the second screen 12. The length of the first screen 11 is greater than the length of the second screen 12. The width of the first screen 11 is equal to or greater than the width of the second screen 12.

[0026] The first screen 11 is uniformly provided with a plurality of groups of first filter hole units along the length direction of the first screen 11, each group of first filter hole units includes a plurality of first filter holes 111 uniformly provided along the length direction of the first screen 11; the second screen 12 is uniformly provided with a plurality of groups of second filter hole units along the length direction of the second screen 12, each group of second filter hole units includes a plurality of second filter holes 121 uniformly provided along the length direction of the second screen 12, and the first filter holes 111 and the second filter holes 121 are provided in one-to-one correspondence. The length and width of each first filter hole 111 are equal to the length and width of each second filter hole 121, respectively, wherein the length of each first filter hole 111 and the length of each second filter hole 121 are 4-10 mm, and the width of each first filter hole 111 and the width of each second filter hole 121 are 1.5-5 mm. When one first screen 11 and one second screen 12 in one screen assembly 1 are attached, one first filter hole 111 and one corresponding second filter hole 121 are used together to form a combined hole, and the combined hole is used to filter activated carbon particles. By adjusting the position between the first screen 11 and the second screen 12, the size of the combined hole can be further adjusted. The width of one combined hole is equal to the width of the first filter hole 111 and the second filter hole 121, and the length of one combined hole is equal to or greater than the length of the first filter hole 111 and the second filter hole 121. In the three screen assemblies 1 of the embodiment, the length of the combined hole formed in each screen assembly 1 decreases in turn from top to bottom, and smaller particle size activated carbon can be filtered in turn. Specifically, when adjusting the size of the combined hole in each screen assembly 1, the position of the first screen 11 can be kept unchanged, and the second screen 12 can be moved along the length direction of the second screen 12 so that the first filter hole 111 on the first screen 11 is misaligned with the second filter hole 121 on the second screen 12. According to actual needs, the length of the combined hole formed is adjusted; along the width direction of the second screen 12, neither the first screen 11 nor the second screen 12 is adjusted, so as to ensure that the first filter hole 111 and the second filter hole 121 are always aligned in the width direction.

[0027] The two side edges of each first screen 11 in the length direction are provided with a plurality of first mounting holes 112 penetrating the thickness direction of the first screen 11, the two side edges of each second screen 12 in the length direction are provided with a plurality of second mounting holes 122 penetrating the thickness direction of the second screen 12, and the hole diameter of the first mounting hole 112 is equal to the hole diameter of the second mounting hole 122. When the second screen 12 is moved to adjust the length of the combined hole, the final position of the second screen 12 needs to be ensured to correspond to one first mounting hole 112 and one second mounting hole 122, so as to be fixed by the clamp assembly 2.

[0028] Further, each clamp assembly 2 comprises a fixing pin and two oppositely arranged clamping plates 21, each of which is provided with a plurality of third mounting holes 211 penetrating through the thickness direction of the clamping plate 21, and the plurality of third mounting holes 211 are arranged along the length direction of the clamping plate 21. When the clamp assembly 2 is used to fix the screen assembly 1, the bottom surface of one clamping plate 21 is attached to the top surface of the first screen 11, and the top surface of the other clamping plate 21 is attached to the bottom surface of the second screen 12, and the fixing pin is simultaneously inserted through the corresponding first mounting hole 112, second mounting hole 122 and third mounting hole 211 to prevent the screen assembly 1 from loosening. In the embodiment, the first mounting hole 112, the second mounting hole 122 and the third mounting hole 211 are all provided as threaded holes, and the fixing pin is provided as a bolt, and the clamp assembly 2 and the screen assembly 1 are fixed by the threaded connection between the threaded holes and the bolt.

[0029] Further, the discharge assembly 7 comprises a plurality of side plates 71, connecting plates 72 and discharge ports 73, and the number of the side plates 71, connecting plates 72 and discharge ports 73 is the same as the number of the screen assemblies 1, and the bottom of each connecting plate 72 is fixedly provided with one discharge port 73. Specifically, one end of the first screen 11 in each screen assembly 1 is fixedly connected with one side plate 71, the first screen 11 is perpendicular to the side plate 71, and the top surface of the first screen 11 is flush with the top edge of the side plate 71, and the bottom edge of the side plate 71 is fixedly connected with one side of one connecting plate 72, and the top surface of the connecting plate 72 is below the top surface of the corresponding first screen 11, so as to ensure that the activated carbon particles left after being filtered by the current screen assembly 1 can fall onto the connecting plate 72 from one end of the first screen 11 under the vibration of the motor 8 and be discharged downward from the corresponding discharge port 73; in addition, the side plate 71 can also ensure that the activated carbon particles left after being screened by the current screen assembly 1 will not fall into the next screen assembly 1. By arranging one side plate 71, one connecting plate 72 and one discharge port 73 at one end of each screen assembly 1, the activated carbon particles of different particle sizes obtained after being screened by each screen assembly 1 can be collected separately, and effective screening can be achieved.

[0030] The two ends of the plurality of connecting plates 72 are fixedly provided with one first fixed plate 74, and the side of the plurality of connecting plates 72 away from the screen assembly 1 is fixedly provided with one second fixed plate 75, and the top surfaces of the first fixed plate 74 and the second fixed plate 75 are above the top surface of the topmost connecting plate 72, so as to ensure that the activated carbon particles falling onto the connecting plate 72 will not fall to the ground.
