Description

Technical Field

[0002] A rotary dust removal cylindrical screen is a device for screening and dust removal of materials through rotary motion. It consists of main parts such as a driving device, a screen cylinder, a frame, and a dust removal system. Among them, the screen cylinder is the core part of the device, and the screening and separation of materials are realized through rotation.

The blockage of the screen holes will significantly reduce the screening area, thereby reducing the passing speed and screening efficiency of the materials. This may lead to the interruption of the production process and affect the overall production plan. The long-term blockage of the screen holes and frequent cleaning may cause wear to the screen cylinder and shorten the service life of the equipment. Therefore, it is necessary to provide a cylindrical screen that can avoid screen mesh blockage and ensure the screening efficiency. Content of the Utility Model

[0038] The rotating ring 21 is fixed at one end of the outer surface of the cylindrical screen 16. The cleaning plate 22 is fixed on one side of the outer surface of the rotating ring 21. The electric push rod 23 is fixedly installed on one side of the outer surface of the cleaning plate 22. The cleaning rod 24 is fixedly connected to the output end of the electric push rod 23.

[0039] The electric push rod 23 is the power source of the anti-blocking component, driving the cleaning rod 24 to expand and contract;

[0040] On one side of the outer surface of the cleaning rod 24, a first limiting groove 25 is provided. On the other side of the outer surface of the cleaning rod 24, a second limiting groove 26 is provided. A first limiting rod 27 penetrates through the inside of the first limiting groove 25, and a second limiting rod 28 penetrates through the inside of the second limiting groove 26. Sieve holes 29 are provided on the outer surface of the cylindrical sieve 16;

[0041] On both sides of the outer surface of the cleaning rod 24, a first limiting groove 25 and a second limiting groove 26 are provided. The first limiting rod 27 penetrates through the first limiting groove 25, and the second limiting rod 28 penetrates through the second limiting groove 26, enabling the cleaning rod 24 to slide stably along the first limiting rod 27 and the second limiting rod 28 under the push of the electric push rod 23, thereby cleaning the outer surface of the cylindrical sieve 16.

[0042] Sieve holes 29 are provided on the outer surface of the cylindrical sieve 16. These sieve holes 29 are the key parts for material screening and are also the places where blockages are likely to occur;

[0043] Working principle:

[0044] When the screening speed slows down;

[0045] First, the staff stops the cylindrical sieve 16 through an external control module and starts the electric push rod 23. The electric push rod 23 extends, synchronously driving the cleaning rod 24 to extend;

[0046] Next, under the limitation of the first limiting rod 27 and the second limiting rod 28, the extension action of the cleaning rod 24 is stable, and the cleaning rod 24 is inserted into the sieve holes 29 to push out the blocked materials;

[0047] Then, through the external control module, the cylindrical sieve 16 is started to rotate 180 degrees, and the above operations are synchronized to clean out the blocked materials on the entire cylindrical sieve 16;

[0048] This step can restore the screening efficiency of the rotary dust removal cylindrical sieve 16 by timely cleaning the blocked sieve holes 29, avoid material accumulation and a decrease in screening speed caused by blockage of the sieve holes 29, and cleaning the sieve holes 29 can reduce the wear of the sieve mesh caused by long-term blockage, thereby extending the service life of the equipment.

The movable block 33 penetrates through the outer surface of the lead screw 32. The movable plate 34 is connected to one side of the outer surface of the movable block 33. The slide rail 35 is fixed on the other side of the outer surface of the chassis 11.

[0053] The slide rail 35 is fixed on the other side of the outer surface of the chassis 11, which provides stable support and guidance for the movable plate 34, ensuring that the movable plate 34 can slide smoothly and transfer the materials to the designated position accurately.

[0054] Working principle:

[0055] When the screened materials fall below the installation frame 12;

[0056] The materials keep piling up directly below, affecting the feeding speed.

[0057] At this time, the staff starts the second motor 31 through the external control module. The second motor 31 drives the lead screw 32 to rotate and will drive the movable block 33 to move on the outer surface of the lead screw 32.

[0058] The movable block 33 will synchronously drive the movable plate 34 to move, pushing the screened materials to both sides for the staff to collect easily.

[0059] This step also, through the movement of the movable plate 34, quickly pushes the piled-up materials to both sides, effectively avoiding the problem of slow feeding speed caused by material accumulation and improving the operation efficiency of the entire production line.
