[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model uses a device with components such as a connecting frame, a rotating frame, and a cleaning roller. The connecting frame and the rotating frame are driven to rotate by a motor. The cleaning roller on the rotating frame is in continuous contact with the outer wall of the screen.

[0019] In this embodiment, each of the two cleaning units includes a fixed frame 23, a limiting ring 232, a rotating shaft 231, and a cleaning roller 24. The fixed frame 23 is located on the screening unit at the end away from the hopper support 4 and is mounted on the base plate 1. The rotating shaft 231 is rotatably connected to the fixed frame 23. The cleaning roller 24 extends along the axial direction of the screening unit.

[0020] In this embodiment, the screening unit is disposed between two cleaning rollers 24. The screening unit includes a rotating frame 211, a screen 22, a fixing ring 212, an arc-shaped stirring plate 34, a connecting frame 21, and a motor 2. The fixed end of the motor 2 is fixedly connected to the first connecting plate 121, and the output end passes through the first connecting plate 121 and is connected to the first end of the connecting frame 21 to drive the connecting frame 21 to rotate. The second end of the connecting frame 21 is fixedly connected to the fixing ring 212, which cooperates with the rotating shaft 231 and is controlled by a limiting ring 232. Limiting; the rotating frame 211 is disposed between the first and second ends of the connecting frame 21 and is fixedly connected to the connecting frame 21; multiple screens 22 are arrayed on the rotating frame 211 to cooperate with the rotating frame 211 to form a cylindrical screening area; multiple arc-shaped stirring plates 34 are provided, and the multiple arc-shaped stirring plates 34 are arranged in a ring array in the screening area and are fixedly connected to the inner wall of the rotating frame 211 respectively; multiple slots 33 are evenly arranged circumferentially on the outer wall of the rotating frame 211, and the slots 33 are corresponding to the impact units.

[0021] The above technical solution can improve the screening effect of the device by setting up the arc-shaped stirring plate 34.

[0022] In this embodiment, the outer wall of the cleaning roller 24 is connected with bristles, the rotating frame 211 is disposed between the two cleaning rollers 24, and the outer wall of the screen 22 is in contact with the bristles so as to clean the screen 22 by the bristles.

[0023] Through the above technical solution, the bristles on the cleaning roller 24 can easily clean the device and prevent clogging.

[0024] In this embodiment, a rubber ring is provided on the outer sleeve of the fixing ring 212 to increase the friction between it and the rotating shaft 231 and prevent slippage between the fixing ring 212 and the rotating shaft 231.

[0025] In this embodiment, the impact unit includes a second connecting plate 31, a pulley 32, and a spring telescopic column 3; the first end of the spring telescopic column 3 is mounted on the feed plate 11, and the second end extends toward the rotating frame 211 and is connected to the second connecting plate 31; a plurality of impact blocks 311 are connected to one end of the second connecting plate 31 near the rotating frame 211, and the plurality of impact blocks 311 are arranged in an array on the second connecting plate 31 and are adapted to the slot 33 to roll and fit with the slot 33 to impact the screen 22.

[0026] Through the above technical solution, the impact block 311 can impact the screen 22, and the impact can improve the screening effect while preventing clogging.

[0027] The implementation principle of the slag vibrating screening device with screen cleaning function provided by this utility model is as follows: During operation, motor 2 drives the connecting frame 21 and rotating frame 211 to rotate via its output end. Slag enters from hopper 12 and falls onto the screen 22 inside the rotating frame 211. The vibration generated by the rotation of the rotating frame 211 causes the slag to be screened on the screen 22. Slag that meets the particle size requirements falls through the screen holes and is discharged onto the discharge plate 11. During this process, while the rotating frame 211 drives the screen 22 to rotate, its outer wall fixing ring 212 contacts the two rotating shafts 231 on the two fixing frames 23, causing the two rotating shafts 231 to rotate synchronously with the rotating frame 211. This drives the two cleaning rollers 24 to continuously clean the outer wall of the screen 22, preventing the screen holes from clogging. At the same time, the arc-shaped stirring plate 34 on the inner wall of the rotating frame 211 rotates with the rotating frame 211 to stir the slag and prevent it from accumulating. The groove 33 on the outer wall of the rotating frame 211 cooperates with the pulley 32. While it rotates, it drives the spring telescopic column 3 to extend and retract, so that the impact block 311 intermittently impacts the rotating frame 211 and the screen 22, enhancing the vibration of the screen 22. Through the synergistic effect of the cleaning structure and the vibration enhancement structure, efficient slag screening and automatic screen cleaning are achieved.

[0028] This invention utilizes a device comprising a connecting frame 21, a rotating frame 211, and a cleaning roller 24. The connecting frame 21 and the rotating frame 211 are driven to rotate by a motor 2. The cleaning roller 24, mounted on the rotating frame 211, maintains continuous contact with the outer wall of the screen 22. As the rotating frame 211 vibrates and screens the screen 22, the cleaning roller 24 simultaneously wipes and cleans the surface of the screen 22, effectively removing adhering slag particles and sticky impurities and preventing screen clogging. Compared to traditional manual cleaning methods, this structure achieves automatic cleaning during the screening process, reducing the number of downtimes for cleaning and improving the continuous operation capability of the device.

[0029] The above are merely preferred embodiments of the present utility model and do not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
