The rotating motor 18 is started to drive the rotating rod 19 to rotate, and the rotating rod 19 drives the main rod 20 to rotate synchronously when it rotates. Because the main rod 20 and the linkage rod 23 are both movably sleeved on the connecting shaft 24, when the main rod 20 drives the connecting shaft 24 to rotate cyclically, the linkage rod 23 will drive the connecting seat 21 to move back and forth, and because the connecting seat 21 is fixedly sleeved on the outside of a connecting column 4, when the connecting seat 21 moves back and forth, a connecting column 4 will synchronously drive the first screen box 5 to move back and forth, and then the wood activated carbon in the first screen box 5 can be screened. And because the filter hole 10 opened on the bottom side of the second screen box 9 is smaller than the circular hole opened on the filter plate 6, the second screen box 9 can perform a second filtration on the wood activated carbon screened for the first time, and the two larger wood activated carbons will be respectively accumulated on the surface of the filter plate 6 and the filter hole 10. After all the filtering is completed, by opening the box door 25 provided on both the first screen box 5 and the second screen box 9, the two sizes of wood activated carbon accumulated on the filter hole 10 and the filter plate 6 can be collected immediately. Together with the smaller wood activated carbon collected in the collection box 3, three different sizes of wood activated carbon can be obtained at the same time after one screening process.

[0022] Specifically, connecting rods 8 are movably provided in the two circular holes located below the two fixed plates 2, and the sides of the two connecting rods 8 close to each other are respectively fixedly connected to the two sides of the second screen box 9, and one end of a connecting rod 8 and a connecting column 4 are fixedly installed with a limiting plate 16. Through the two connecting rods 8, when the first screen box 5 drives the second screen box 9 to move back and forth, the two connecting rods 8 can move in the circular holes opened at the bottom of the two fixed plates 2, which can provide a stable guiding effect, and through the two limiting plates 16, the connecting column 4 and the connecting rod 8 can be prevented from falling off.

[0023] Specifically, a connecting pipe 11 is fixedly installed on the bottom side of the first screen box 5, and the connecting pipe 11 is connected to the first screen box 5.

The two inclined blocks 7 are symmetrically arranged. The connecting pipe 11 is located between the two inclined blocks 7. The filter plate 6 is located above the two inclined blocks 7. A feed port 14 is fixedly installed on the top side of the first screen box 5. The feed port 14 is connected to the first screen box 5. A sealing plug 15 is arranged in the feed port 14. Two guide plates 13 are fixedly installed on the bottom side of the second screen box 9. The two guide plates 13 are fixedly installed on the bottom side of the second screen box 9. The plates 13 are arranged at an angle and symmetrically, and the two guide plates 13 are both facing the collecting box 3. Through the connecting pipe 11, the wood activated carbon filtered once will enter the second screen box 9 along the connecting pipe 11. The two inclined blocks 7 arranged in the first screen box 5 can avoid the problem of wood activated carbon accumulating at the corner of the first screen box 5 when it falls from the filter plate 6. Through the four connecting blocks 12, because the two sides of the four connecting blocks 12 are respectively fixedly connected to the bottom side of the first screen box 5 and the top side of the second screen box 9, when the first screen box 5 moves back and forth, the second screen box 9 can also move synchronously, and the two guide plates 13 fixedly installed on the bottom side of the second screen box 9 can make the wood activated carbon filtered for the second time fall accurately into the collecting box 3.

[0024] The screening device for producing wood activated carbon is connected to 220V mains electricity, and the main controller can be a conventional known device for control such as a computer.

[0025] In use: when it is necessary to screen the wood activated carbon, pour the wood activated carbon into the first screen box 5 from the feed port 14, then insert the sealing plug 15 into the feed port 14, and then start the rotating motor 18 to drive the rotating rod 19 to rotate. When the rotating rod 19 rotates, the main rod 20 is rotated synchronously. Because the main rod 20 and the linkage rod 23 are both movably sleeved on the connecting shaft 24, when the main rod 20 drives the connecting shaft 24 to rotate cyclically, the linkage rod 23 will drive the connecting seat 21 to move back and forth, and because the connecting seat 21 is fixedly sleeved on a connecting shaft 24, the connecting shaft 24 is rotated cyclically. The outer side of the connecting column 4, so when the connecting seat 21 moves back and forth, a connecting column 4 will synchronously drive the first screen box 5 to move back and forth, and through the filter plate 6 set in the first screen box 5, some smaller wood activated carbon can be filtered during the reciprocating movement, while some large wood activated carbon will remain on the surface of the filter plate 6, and the filtered wood activated carbon will fall into the second screen box 9 along the connecting pipe 11, and the two inclined blocks 7 set in the first screen box 5 can prevent the wood activated carbon from accumulating on the filter plate 6 when it falls off. The problem of the corner of the first screen box 5 is solved by setting four connecting blocks 12. Because the two sides of the four connecting blocks 12 are respectively fixedly connected to the bottom side of the first screen box 5 and the top side of the second screen box 9, when the first screen box 5 moves back and forth, the second screen box 9 can also move synchronously. When the wood activated carbon enters the second screen box 9, because the filter hole 10 opened on the bottom side of the second screen box 9 is smaller than the circular hole opened on the filter plate 6, the second screen box 9 can perform a second filtration on the wood activated carbon that has been screened for the first time. Then the wood activated carbon filtered by the second screening will fall into the collection box 3 along the drainage plate 13, and some larger wood activated carbon will accumulate on the surface of the filter hole 10. When the wood activated carbon is screened after multiple reciprocating movements, by opening the box doors 25 set in the first screen box 5 and the second screen box 9, the two sizes of wood activated carbon accumulated on the filter hole 10 and the filter plate 6 can be collected. Together with the smaller wood activated carbon collected in the collection box 3, three different sizes of wood activated carbon can be obtained at the same time after one screening process.
