Description
Technical Field
[0001] The utility model relates to the technical field of level meters, in particular to an anti-scaling device for a level meter. Background Art
[0002] Level measurement usually refers to the detection of the height of materials (solid or liquid) in closed or open containers in industrial production processes. If the material height is detected continuously, it is called continuous measurement. If only the material height is detected to see whether it has reached a certain position, it is called limit measurement. The instrument that completes this measurement task is called a level meter.
[0003] The existing publication number CN213209194U proposes an anti-scaling device for a level meter, which forms a strong rotating wind on the detection surface of the level meter and blows it below the detection surface of the level meter. The rotating wind column pushes away the dust and fog below the level meter, which not only keeps the detection surface of the level meter clean, but also reduces the concentration of dust and fog below the level meter to improve the accuracy of the level meter. However, in actual work, there is not only dust but also water mist in the crushing chamber of the crusher. The water mist will cause the dust to adhere to the level meter, and the dust will be dried and hardened, which will affect the detection data of the level meter.
[0004] Therefore, a device for preventing fouling of a level meter is proposed. Utility Model Content

[0026] like Figure 1 , Figure 2 As shown, the rotating assembly 4 includes a fixed slide 401 fixedly connected to the top of the level meter 1, and the fixed slide 401 is internally movably connected with movable rods 402 arranged equidistantly in a circumferential manner, and the top of the movable rod 402 is fixedly connected with a driven gear 403.
