Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] When implementing: Figure 1-4 As shown, a rotary drum air-cooled screen includes a support leg 1, a drum screen 2 and a support frame 6: the drum screen 2 is provided on the inner side of the support leg 1, the support frame 6 is provided inside the drum screen 2, a stirring structure 20 is provided on the side of the drum screen 2, a cooling structure 21 is provided on the upper end of the drum screen 2, and a screening structure 22 is provided on the surface of the drum screen 2;

[0023] The screening structure 22 includes a first filter ring 18 and a second filter ring 19. The surface of the cylindrical screen 2 is provided with the first filter ring 18 and the surface of the cylindrical screen 2 is provided with the second filter ring 19.

[0024] When the device is in use, the material is first poured into the interior of the drum screen 2 through the feed port 4, and then physically slides to the surface of the filter plate 17. During the sliding process, the drum screen 2 is driven to rotate by the stirring of the stirring structure 20 and the reducer 5, so that when the material passes through the first filter ring 18, the smaller material falls from the lower end of the first filter ring 18 to the inside of the first discharge port 10. At this time, the larger material passes through the filter plate 17 and enters the interior of the second filter ring 19. After stirring and rotation, the larger material passes through the lower end of the second filter ring 19 and enters the interior of the second filter ring 19, so as to screen the material.

[0025] A connecting block 3 is provided on the side of the drum screen 2 , and the connecting block 3 is rotatably connected to the drum screen 2 . A feed port 4 is provided on the upper end of the connecting block 3 .

[0026] A baffle 14 is provided inside the connecting block 3 , and the distance between the first filter ring 18 and the baffle 14 is smaller than the distance between the second filter ring 19 and the baffle 14 .

[0027] The stirring structure 20 includes a motor 12, a rotating shaft 13 and a stirring rod 15. The motor 12 is disposed on the side of the baffle 14, the rotating shaft 13 is disposed on the side of the motor 12, and the stirring rod 15 is disposed on the surface of the rotating shaft 13.

[0028] When the device is in use, the material first enters the interior of the drum screen 2 through the feed port 4, and then the motor 12 is turned on to drive the rotating shaft 13 to rotate, and the rotating shaft 13 drives the stirring rod 15 to rotate to stir the material to prevent the material from piling up and sticking together, resulting in smaller materials and larger materials being unable to be screened, resulting in reduced screening efficiency.

[0029] The rotating shaft 13 passes through the baffle 14, and the surface of the stirring rod 15 is provided with a scraper 16, and the shape of the scraper 16 fits the first filter ring 18 and the second filter ring 19;

[0030] When the device is in use, the motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the stirring rod 15 to rotate while driving the scraper 16 to rotate. The scraper 16 cleans the inner walls of the first filter ring 18 and the second filter ring 19 to prevent the inner wall from being clogged due to excessive material sticking to the inner wall.

[0031] A reducer 5 is provided on the side of the support leg 1, the drum screen 2 is rotatably connected to the support leg 1, and one end of the reducer 5 is connected to one end of the support frame 6;

[0032] When the device is in use, the material first enters the interior of the drum screen 2 through the feed port 4, and then the reducer 5 is turned on to rotate the reducer 5 to drive the support frame 6 to rotate, thereby driving the drum screen 2 to rotate through the support frame 6, so that the material is rolled by the rotation of the drum screen 2 to prevent the material from accumulating and being unable to be filtered out.

[0033] A first discharge port 10 is provided at the lower end of the first filter ring 18 , a second discharge port 11 is provided at the lower end of the second filter ring 19 , and a filter plate 17 is provided in the middle of the drum screen 2 .

[0034] The cooling structure 21 includes a blocking shell 7, a suction fan 8 and an air outlet 9. The upper end of the drum screen 2 is provided with the blocking shell 7, the upper end of the blocking shell 7 is provided with the suction fan 8, and the lower end of the blocking shell 7 is provided with an air outlet 9;

[0035] When the device is in use and the material needs to be cooled, the suction fan 8 is turned on to allow the suction fan 8 to suck the external air into the interior of the blocking shell 7, and then blow the gas out through the air outlet 9. When the material is stirred, the material flies upward due to the stirring force, and the blown gas blows the material back to the bottom, so as to prevent the material from splashing out of the drum screen 2. The material is continuously cooled by the airflow, thereby improving the cooling effect and preventing the cooling effect of the drum screen 2 from being affected by weather and environment.

[0036] When the utility model is in use, the material is firstly passed through the feed port 4 into the interior of the drum screen 2. At this time, the reducer 5 is turned on, so that the reducer 5 drives the support frame 6 to rotate, thereby driving the drum screen 2 to rotate, so that the material rotates and moves forward to prevent the material from piling up. Subsequently, the motor 12 is turned on, so that the motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the stirring rod 15 to rotate, so that the stirring rod 15 drives the scraper 16 to rotate, thereby not only stirring the material, but also removing the material stuck to the inner walls of the first filter ring 18 and the second filter ring 19, thereby improving the effect of material separation. In order to reduce the problem of materials sticking together and being unable to be screened due to accumulation, the suction fan 8 is turned on at this time, so that the suction fan 8 sucks the external air into the interior of the blocking shell 7, and continuously blows the air out from the air outlet 9 to cool the material. Then the smaller materials are screened by the first filter ring 18, pass through the lower end of the first filter ring 18 and fall to the internal discharge of the first discharge port 10, while the larger materials pass through the filter plate 17 into the interior of the second filter ring 19, and pass through the lower end of the second filter ring 19 into the internal discharge of the second discharge port 11, so as to achieve the purpose of cooling and screening the materials.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
