[0002] Generally, during the production of activated carbon, the particle size of the produced activated carbon is uneven and mixed together. Therefore, it is often necessary to screen it to make the produced activated carbon particles as uniform as possible. This allows the activated carbon to be loaded more evenly during use and reduces gaps. However, the activated carbon screening device in the prior art has low screening efficiency for activated carbon and a slow screening speed for activated carbon of different sizes, which affects the subsequent processing and use of the activated carbon. At the same time, if too much activated carbon is fed at one time, it will cause blockage. Therefore, the present application proposes an activated carbon screening device. Utility Model Content

Specifically, when the first motor When the cam 5 is driven to rotate, the cam 5 intermittently contacts the bottom of the connecting rod 9, which continuously pushes up the connecting rod 9. Furthermore, since one end of the connecting rod 9 is fixedly connected to the side wall of the vertical plate 10, and the bottoms of the two vertical plates 10 are connected by a first screen plate 12, and the slider 7 slides up and down in the slide groove 11, when the cam 5 continuously pushes up the connecting rod 9, the first screen plate 12 also continuously moves up and down, screening the activated carbon falling on the first screen plate 12. Similarly, the activated carbon will be screened through multiple first screening mechanisms. It should be noted here that the aperture of the first screen plate 12 decreases from top to bottom.

A second motor 16 is installed at the center of the outer side of the top of the unloading hopper 13, and the output end of the second motor 16 extends through the top of the unloading hopper 13 to the inner cavity of the unloading hopper 13 and is connected to a second rotating shaft 17. A plurality of stirring rods 18 are evenly arranged on the second rotating shaft 17. The second rotating shaft 17 located in the unloading channel 15 There are a number of stirring blades 19 evenly arranged on it. Specifically, the activated carbon to be screened is fed into the inner cavity of the lower hopper 13 from the two feed ports 14 opened on the top of the lower hopper 13. At this time, the second motor 16 is started, and the second motor 16 drives the second rotating shaft 17 and the stirring rod 18 to rotate, so as to break up the activated carbon first. When the activated carbon passes through the lower feeding channel 15, it is transported by a number of stirring blades 19 evenly arranged on the second rotating shaft 17 in the lower feeding channel 15, so as to avoid blockage due to too much activated carbon being fed at one time.

[0027] Furthermore, the second screening mechanism includes a third motor 20 installed on the outside of the bottom of the device body 1, the output end of the third motor 20 extends through the bottom of the device body 1 to the inner cavity of the device body 1 and is connected to a third rotating shaft 21, the third rotating shaft 21 is provided with a rotating sleeve 22, and two second sieve plates 23 are symmetrically connected on both sides of the rotating sleeve 22, and the other ends of the two second sieve plates 23 are fixedly connected to the side wall of the inner cavity of the device body 1, and a toggle component is provided on the top of the third rotating shaft 21, and the toggle component includes a fixing rod 24 threadedly connected to the top of the third rotating shaft 21, and two symmetrically connected on both sides of the bottom of the fixing rod 24 by bolts 25.

Specifically, by starting the third motor 20, the third motor 20 drives the third rotating shaft 21 to rotate, and at the same time drives the fixed rod 24 threadedly connected to the top of the third rotating shaft 21 to rotate, so that the toggle plate 26 rotates on the second sieve plate 23, and the activated carbon on the second sieve plate 23 is toggled, and screening is achieved while toggling. The fixed rod 24 and the third rotation are threaded, so that the fixed rod 24 can be disassembled, and the toggle plate 26 is fixed to the fixed rod 24 by the bolt 25, which facilitates the replacement of the toggle plate 26 and improves the practicality of the device.

[0028] Furthermore, a discharge solenoid valve 27 is installed at the discharge port 2. Specifically, by adjusting the opening of the valve port, the flow rate of the activated carbon discharge can be controlled to ensure the stability and accuracy of the discharge process.

[0029] It can be seen from the above technical solution that when in use, the activated carbon that needs to be screened is passed into the inner cavity of the lower hopper 13 from the two feed ports 14 opened at the top of the lower hopper 13. At this time, the second motor 16 is started, and the second motor 16 drives the second rotating shaft 17 and the stirring rod 18 to rotate, so that the activated carbon is first broken up, and then when it passes through the lower channel 15, it is transported by a number of stirring blades 19 evenly arranged on the second rotating shaft 17 in the lower channel 15 to avoid blockage due to too much activated carbon being fed at one time. The activated carbon passes through the multiple first screening mechanisms arranged in sequence from top to bottom in the inner cavity of the device body 1, and the activated carbon is screened for the first time. Specifically, by starting the first motor 3, the first motor 3 drives the second rotating shaft 17 and the stirring rod 18 to rotate, so as to break up the activated carbon. The first rotating shaft 4 is driven to rotate, and at the same time, the cam 5 connected thereto is driven to rotate, so that the cam 5 intermittently contacts the bottom of the connecting rod 9, which will continuously lift the connecting rod 9. Furthermore, since one end of the connecting rod 9 is fixedly connected to the side wall of the vertical plate 10, and the bottoms of the two vertical plates 10 are connected by a first sieve plate 12, and the slider 7 slides up and down in the slide groove 11, when the cam 5 continuously lifts the connecting rod 9, the first sieve plate 12 will also continuously move up and down, screening the activated carbon falling on the first sieve plate 12. By analogy, the activated carbon will be screened through multiple first screening mechanisms. It should be noted here that the aperture of the first sieve plate 12 decreases from top to bottom.

[0030] The activated carbon that has completed the first screening will fall into the second screening mechanism set at the bottom of the inner cavity of the device body 1, and the activated carbon will be screened again. Specifically, by starting the third motor 20, the third motor 20 drives the third rotating shaft 21 to rotate, and at the same time drives the fixing rod 24 threadedly connected to the top of the third rotating shaft 21 to rotate, so that the toggle plate 26 rotates on the second sieve plate 23, and the activated carbon on the second sieve plate 23 is toggled, and screening is achieved while toggling. The fixing rod 24 is threadedly arranged between the fixing rod 24 and the third rotation, so that the fixing rod 24 can be disassembled, and the toggle plate 26 is fixed to the fixing rod 24 by the bolt 25, which is convenient for replacing the toggle plate 26, thereby improving the practicality of the device. It should be noted here that the second sieve plate 23 The aperture size is smaller than the aperture size of the first sieve plate 12 located at the bottom, and the activated carbon is finally discharged from the two discharge ports 2 symmetrically opened at the bottom of the device body 1, and a discharge solenoid valve 27 is also installed at the discharge port 2. By adjusting the opening of the valve port, the flow rate of the activated carbon discharge can be controlled to ensure the stability and accuracy of the discharge process. Finally, by opening the box door of the device body 1, the activated carbon screened out from the first sieve plate 12 and the second sieve plate 23 can be taken out, which solves the problem that the activated carbon screening device in the prior art has low screening efficiency for activated carbon and slow screening speed for activated carbon of different sizes, which affects the subsequent processing and use of the activated carbon. At the same time, if too much activated carbon is fed at one time, it will cause blockage.
