Description

Technical Field

[0001] The utility model relates to the technical field of vertical mill material distribution, and more specifically to a vertical mill uniform material distribution device. Background Art

[0002] Vertical mill is a grinding equipment that integrates fine crushing, drying, grinding, powder selection and conveying. It is widely used in the grinding and ultra-fine grinding of various solid materials in cement, building materials, electric power, metallurgy, chemical industry, non-metallic minerals and other industries. When using vertical mill for tailings treatment, when the tailings are sent into the vertical mill, the tailings tend to be concentrated in a certain place, which increases the load of the vertical mill and reduces the efficiency of the vertical mill. Therefore, it is necessary to increase the distribution device to let the tailings fall into the vertical mill and evenly disperse the tailings, save energy consumption, and reduce equipment failures and wear.

[0003] After searching, a material distribution device of a vertical mill disclosed in publication number CN209452018U includes a device body, a fixed frame is connected to the outer shell of the device body, fixed plates are welded at both ends of the fixed frame, and the fixed plates are screwed to the outer shell of the vertical mill. The device body includes an extrusion mechanism and a material leveling mechanism. The extrusion mechanism includes a special-shaped shell one, two rotating shafts with the same structure are rotatably connected in the shell one, an extrusion roller is connected to the outer shell of the rotating shaft, one end of the rotating shaft is clamped in the output shaft of motor one, and the motor one is fixedly connected to the shell one. A discharge port is provided at a lower end of the shell, and a material leveling mechanism is provided at the lower end of the discharge port.

[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, the interior of the main body is located below the extrusion roller and has a cavity of a certain volume. When the material is extruded and transported to the interior of the main body, if the materials are piled up on each other, they cannot flow out well through the bottom of the main body. At the same time, the bracket will also cause certain obstructions, and thus the material cannot be discharged downward well. For this reason, we propose a vertical mill uniform distribution device.
