Description

Technical Field

[0001] The utility model relates to the technical field of rolling screens, and more specifically to a rolling screen beating and cleaning device. Background Art

[0002] The rolling screen is a device that screens the material when the material continuously passes through the rotating cylindrical screen. The fine material falls into the fine particle hopper through the screen holes, and the coarse particles fall into the coarse particle hopper from the end of the columnar screen. The rolling screen is used in the production process of carbon ladle refractory materials, silicon carbide, metallic silicon, etc. In order to prevent the rolling screen from being blocked, a beating device is set on the rolling screen.

[0003] After searching, the utility model patent with announcement number CN217748096U discloses a rolling screen beating and cleaning device, including two bases and a rolling screen, the top outer walls of the two bases are respectively fixedly connected to a first frame and a second frame, the outer wall of one side of the first frame is rotatably connected to a symmetrically arranged first rotating rod and a second rotating rod, the outer walls of the first rotating rod and the second rotating rod are respectively fixedly connected to an equidistantly distributed first fixed seat and a second fixed seat; when it is necessary to clean the rolling screen, start the reduction motor, the reduction motor cooperates with the mounting frame, the mounting hole, the annular groove and the rotating ring to drive the second rotating rod to rotate, the second rotating rod drives the second fixed seat to rotate, the second fixed seat drives the second support rod to rotate, the second support rod drives the second beating ball to beat one side of the rolling screen, so that the granular material adhered to one side of the rolling screen can be beaten and cleaned, which is more practical and suitable for wide promotion and use.

[0004] However, the above patent still has the following shortcomings: the radial position of the beating ball beating the side of the rolling screen is fixed, the beating part will be subjected to a greater vibration force, and the vibrating force around the beating part is smaller, which is not convenient to ensure the uniformity and quality of beating cleaning; and the beating ball repeatedly hitting the screen will cause wear, and the beating effect of the worn beating ball will be weakened, affecting the beating effect, and it is not convenient to replace it. For this reason, we propose a rolling screen beating cleaning device. Utility Model Content

[0028] For details, please refer to Figure 1 and Figure 3 The beating mechanism 11 includes a connecting column 14 fixedly connected to the square column 10, a beating ball 15 is fixedly connected to the end of the connecting column 14, two screw holes 16 are provided on the side of the beating ball 15, a beating sleeve 17 is provided on the outer side of the beating ball 15, a bolt 18 is provided on the outer side of the beating sleeve 17, and the end of the bolt 18 is threadedly sleeved with the inner cavity of the screw hole 16.

[0029] In this embodiment, the beating sleeve 17 is installed on the outer side of the beating ball 15 through the cooperation of the screw hole 16 and the bolt 18.

[0030] For details, please refer to Figure 1 and Figure 2 The driving mechanism 5 includes two sets of driving frames 19 fixedly connected to the top surface of the base 1, and the inner sides of the two sets of driving frames 19 are rotatably connected with driving rods 20 respectively.
