[0002] The working part of the cylindrical screen is cylindrical. The whole screen rotates around the axis of the cylinder. The axis is generally installed at a small inclination angle. The cylindrical screen is widely used for screening dry powdery or granular materials in industries such as metallurgy, building materials, chemical industry, grain, medicine, abrasives and chemical fertilizers. It is especially suitable for dry production of machine-made sand and can also be used for screening granular wet materials.

[0003] According to the Chinese patent disclosure document with the patent publication number CN208486121U, a kind of enclosed cylindrical screen is proposed, which includes a frame and a screen cylinder installed on the frame.

A combined guard is arranged above the screen cylinder, and the combined guard includes an upper guard and two side guards respectively fixed on both sides of the frame.

[0004] Although the above patent can use the cylindrical screen to screen raw materials, in the actual use process, the screen cylinder of this patent is prone to screen hole blockage during screening, thus limiting the screening efficiency and affecting the screening effect of raw materials. Summary of the Utility Model

[0005] In order to overcome the disadvantages mentioned in the above background art, the utility model provides a stable and durable enclosed cylindrical screen to solve the above problems.

The integrated controller is fixedly installed on the mounting rack. The mounting rings are symmetrically and fixedly installed inside the mounting rack. The screen cylinder is rotatably installed between the two mounting rings. The feeding hopper inclined towards the inside of the screen cylinder is fixedly installed on the mounting rack. The stepping motor electrically connected with the integrated controller is fixedly installed on the mounting rack. The output shaft of the stepping motor is fixedly connected with the screen cylinder. It further includes a scraping component. A scraping component for unclogging the screen cylinder is arranged inside the mounting rack. The scraping component includes a guide rod, a threaded rod, a toothed ring, a gear and a scraping ring.

Detailed implementation mode

[0020] The present utility model will be described in detail below in conjunction with the attached drawings and specific embodiments, but it is not intended to limit the present utility model.

[0021] Embodiment: A stable and durable enclosed cylindrical sieve, as Figures 1-4 shown, comprising a mounting frame 1, an integrated controller 2, a blanking hopper 3, a mounting ring 4, a sieve cylinder 5 and a stepping motor 6. The left part in front of the mounting frame 1 is bolted with an integrated controller 2. The mounting rings 4 are symmetrically welded left and right inside the mounting frame 1. A sieve cylinder 5 is rotatably mounted between the two mounting rings 4. The left side of the mounting frame 1 is bolted with a blanking hopper 3 inclined into the sieve cylinder 5. The right side of the mounting frame 1 is bolted with a stepping motor 6 electrically connected to the integrated controller 2. The output shaft of the stepping motor 6 is connected to the sieve cylinder 5 through a coupling. It further comprises a scraping component. A scraping component for unclogging the sieve cylinder 5 is provided inside the mounting frame 1. The scraping component includes a guide rod 7, a threaded rod 8, a gear ring 9, a gear 10 and a scraping ring 11. The guide rod 7 is bolted between the bottoms of the two mounting rings 4. The threaded rod 8 is rotatably mounted between the tops of the two mounting rings 4. The threaded rod 8 is a double-threaded screw. A gear ring 9 is fixedly mounted circumferentially on the left part of the sieve cylinder 5. The left end of the threaded rod 8 is connected through a coupling with a gear 10 meshing with the gear ring 9. A scraping ring 11 in contact with the outer side wall of the sieve cylinder 5 is threadedly connected to the threaded rod 8.

[0022] As Figure 4 shown, it further comprises elastic bumps 12. A plurality of elastic bumps 12 are provided circumferentially at the contact of the scraping ring 11 with the outer side wall of the sieve cylinder 5. When the scraping ring 11 moves, the elastic bumps 12 will push against the sieve holes of the sieve cylinder 5.

[0023] As Figure 1 , Figure 2 and Figure 5 shown, it further comprises a spraying component. The spraying component includes a water tank 13, a water pump 14, a sprinkler 15 and a connecting pipe 16. The middle of the top surface of the mounting frame 1 is bolted with a water tank 13. The inner bottom surface of the water tank 13 is bolted with a water pump 14 electrically connected to the integrated controller 2. Five sprinklers 15 electrically connected to the integrated controller 2 are respectively bolted symmetrically front and back inside the mounting frame 1. The sprinklers 15 all face the direction of the sieve cylinder 5. Connecting pipes 16 are respectively and hermetically connected between the sprinklers 15 and the water pump 14.

[0024] As Figure 1 , Figure 2 and Figure 5 shown, it further includes a collection cart 17. An internally lower part of the mounting rack 1 is provided with a slidably ejectable collection cart 17. When the collection cart 17 is pushed into the mounting rack 1, it is located directly below the sieve cylinder 5. Residue, waste water, etc. falling from the sieve cylinder 5 will fall into the collection cart 17 for collection.

[0025] As Figure 2 and Figure 3 shown, it further includes a spiral stirring plate 18. The spiral stirring plate 18 is welded to the inner side wall of the sieve cylinder 5, and the spiral stirring plate 18 will disperse the material as the sieve cylinder 5 rotates.

[0026] When it is necessary to use the cylindrical sieve to screen the material, first push the collection cart 17 into the mounting rack 1, and then start the screening program through the integrated controller 2. The integrated controller 2 will start the stepping motor 6. The output shaft of the stepping motor 6 will drive the sieve cylinder 5 to rotate. Then pour the material to be screened into the sieve cylinder 5 through the feed hopper 3, so as to screen and process the material through the rotating sieve cylinder 5. The spiral stirring plate 18 will disperse the material as the sieve cylinder 5 rotates, thereby preventing the material from accumulating, and further improving the screening efficiency while ensuring the screening effect. During this period, as the sieve cylinder 5 rotates, the sieve cylinder 5 will drive the gear ring 9 to rotate synchronously. The gear ring 9 will cause the threaded rod 8 to rotate through the gear 10 meshing with it. The threaded rod 8 will drive the scraping ring 11 to move reciprocally left and right along the guide rod 7 on the outer side wall of the sieve cylinder 5 through the double - thread. When the scraping ring 11 moves, it will push against the sieve holes of the sieve cylinder 5 through the elastic bumps 12, so as to dredge the sieve cylinder 5 and prevent blockage, thereby ensuring the screening effect of the sieve cylinder 5 on the material. During this period, the integrated controller 2 will also start the water pump 14 and the sprayer 15. The water pump 14 will extract the clear water in the water tank 13 and transmit it to the sprayer 15 through the connecting pipe 16. The sprayer 15 will evenly spray the clear water towards the sieve cylinder 5, so as to cooperate with the sieve cylinder 5 to screen the material. The screened residue and waste water will fall into the collection cart 17 for collection. When the screening of the material is completed, push out the collection cart 17 for cleaning.

[0027] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
