[0023] Working principle: In the first step, when the continuous drying and screening device for activated carbon preparation is used, the activated carbon to be screened is fed into the upper bin 12, and then the activated carbon is introduced into the arc sieve plate 3 from the material pipe on the upper bin 12, and the servo motor 48 is started. The output shaft of the servo motor 48 drives the gear 49 to rotate, and the gear 49 is meshed and installed with the gear ring 46. The gear 49 rotates to drive the gear ring 46 to rotate, and the gear ring 46 is fixedly installed with the drum screen 4, so that the gear ring 46 rotates to drive the drum screen 4 to rotate, and the drum screen 4 rotates to drive the toggle block 41 to rotate, and the toggle block 41 rotates to toggle the rotating toggle block 31, and the rotating toggle block 31 is forced to drive the arc sieve plate 3, and the arc sieve plate 3 is forced to shake the arc sieve plate 3 is screened, and the screened activated carbon falls into the drum screen 4, and the rotating drum screen 4 performs secondary screening on the activated carbon screened by the arc sieve plate 3, and the activated carbon screened by the drum screen 4 falls into the trapezoidal collecting tank 17. The continuous drying and screening device for preparing activated carbon is designed as an arc sieve plate 3 for preliminary screening, and the drum screen 4 performs secondary screening, and the mesh number of the drum screen 4 is smaller than the mesh number of the arc sieve plate 3, so that when the activated carbon is screened, continuous screening can be performed, thereby improving the screening accuracy, keeping the particle size distribution uniform, and the arc sieve plate 3 cooperates with the drum screen 4 to continuously screen, and a large amount of activated carbon can be screened, thereby effectively improving the production efficiency.

[0024] In the second step, when the continuous drying and screening device for preparing activated carbon is used, the activated carbon to be screened is fed into the upper bin 12, and then the activated carbon is introduced from the material pipe on the upper bin 12 into the drying material pipe 32, and then introduced into the arc sieve plate 3 from the drying material pipe 32. During this period, the heating component 33 is started, and the heating component 33 heats the drying material pipe 32, thereby heating the activated carbon in the drying material pipe 32, and then the activated carbon after heating and drying falls into the arc sieve plate 3, and the servo motor 48 is started, and then the arc sieve plate 3 and the drum screen 4 cooperate to finely screen the activated carbon. By adding the heating component 33 to the drying material pipe 32 of the continuous drying and screening device for preparing activated carbon, when the activated carbon is screened, the heating component 33 is started to heat the drying material pipe 32, and then the activated carbon in the drying material pipe 32 is heated and dried, so as to avoid the activated carbon from accumulating into blocks due to moisture and affecting the screening effect, thereby effectively improving the working efficiency of activated carbon screening.

[0025] The third step, when the continuous drying and screening device for activated carbon preparation is used, the activated carbon to be screened is transported to the arc sieve plate 3, and the servo motor 48 is started. The output shaft of the servo motor 48 drives the gear 49 to rotate, and the gear 49 is meshed and installed with the gear ring 46. The rotation of the gear 49 drives the gear ring 46 to rotate, and the gear ring 46 is fixedly installed with the drum screen 4. The rotation of the gear ring 46 drives the drum screen 4 to rotate. The rotation of the drum screen 4 drives the fixed ring 42 to rotate in the air inlet chamber 21. The rotation of the fixed ring 42 drives the sliding plate 44 to rotate. Because the air inlet chamber 21 and the fixed ring 42 are eccentrically installed, the sealing chamber formed between the sliding plate 44 and the air inlet chamber 21 is larger at the bottom and smaller at the top. As the gap becomes smaller, the sliding plate 44 rotates to squeeze the spring 45, and the spring 45 is deformed by force until the gap becomes larger. , the spring 45 is reset to push the sliding plate 44 out of the slide groove 43, so that the sliding plate 44 fits with the inner wall of the air inlet chamber 21 to form a sealed cavity, and then the large cavity located below is connected with the suction pipe 52, and the small cavity located above is connected with the air supply pipe 53. When the fixed ring 42 drives the sliding plate 44 to rotate, the air in the large cavity is squeezed into the small cavity, and then the air is transported from the small cavity to the protective shell 2 through the air supply pipe 53. The continuous drying and screening device for preparing activated carbon is designed to be driven by the drum screen 4 to drive the fixed ring 42, and the fixed ring 42 rotates to drive the sliding plate 44, and then squeezes the inner cavity of the air inlet chamber 21 to drive air circulation, so that the drum screen 4 drives the airflow into the protective shell 2 while performing rolling screening, and the activated carbon screened in the protective shell 2 is ventilated and dried, thereby effectively improving the practicality of the device.

[0026] The fourth step is to place the drying bag in the drying box 5 when the continuous drying and screening device for preparing activated carbon is used, and then start the servo motor 48, so that the drum screen 4 and the arc-shaped screen plate 3 cooperate to screen the activated carbon. When the drum screen 4 rotates, it drives the fixed ring 42 to rotate, and the fixed ring 42 rotates to drive the sliding plate 44 to rotate. As the gap becomes smaller, the sliding plate 44 rotates to squeeze the spring 45, and the spring 45 is deformed by the force. When the gap becomes larger, the spring 45 resets and pushes the sliding plate 44 out of the slide groove 43, so that the sliding plate 44 fits the inner wall of the air inlet cavity 21 to form a sealed cavity, and then the sliding plate 44 rotates to squeeze the inner cavity of the air inlet cavity 21 to drive air circulation, and the air enters from the air inlet 51. The air is dried in the drying box 5, and then the air intake pipe 52 transports the dried air to the air inlet chamber 21, and then the air inlet chamber 21 is transported to the protective shell 2 through the air supply pipe 53. By adding the drying box 5 to the continuous drying and screening device for preparing activated carbon, the drying box 5 dries the air while the drum screen 4 rotates to drive the fixed ring 42, and the fixed ring 42 rotates to drive the sliding plate 44, thereby squeezing the inner cavity of the air inlet chamber 21 to drive the air circulation. The dried air is then transported to the protective shell 2 through the sliding plate 44 and the air inlet chamber 21 through the air intake pipe 52, thereby reducing the moisture content of the air in the protective shell 2, thereby effectively improving the drying effect of the activated carbon.

[0027] The fifth step is that when the continuous drying and screening device for the preparation of activated carbon is used, the activated carbon is introduced from the material pipe on the upper bin 12 into the arc sieve plate 3, the servo motor 48 is started to drive the drum screen 4 to rotate, the rotation of the drum screen 4 drives the toggle block 41 to rotate, the toggle block 41 rotates and toggle the rotating toggle block 31, the rotating toggle block 31 is forced to drive the arc sieve plate 3, the arc sieve plate 3 is forced to shake to screen the activated carbon inside, the screened activated carbon falls into the drum screen 4, the rotating drum screen 4 performs secondary screening on the activated carbon screened by the arc sieve plate 3, the activated carbon screened by the drum screen 4 falls into the trapezoidal collecting tank 17, and the remaining The activated carbon after preliminary screening in the arc sieve plate 3 is discharged through the discharge pipe 14, the activated carbon remaining in the drum screen 4 after secondary screening is discharged through the discharge port 15, and then the activated carbon remaining in the trapezoidal collecting tank 17 is discharged through the discharge port 2 16. By designing a continuous drying and screening device for preparing activated carbon and adding a discharge pipe 14, a discharge port 15, and a discharge port 2 16, after the activated carbon is screened, it can be discharged separately from the discharge pipe 14, the discharge port 15, and the discharge port 2 16 according to the different fineness of the activated carbon, thereby accurately dividing the screened activated carbon, and effectively improving the practicability of the device.
