Automatic stator blade distance adjusting device for vertical roller mill powder concentrator

Abstract

The invention discloses an automatic stator blade distance adjusting device for a vertical roller mill powder concentrator. The automatic stator blade distance adjusting device comprises an annular driving disc which is horizontally arranged in the center of a powder concentrator shell, wherein outside notch grooves which have the equal number with the stator blades of the powder concentrator and are uniformly arranged are arranged on the annular driving disc; a pin shaft is inserted into each outside notch groove; the pin shaft is vertically and fixedly connected to a horizontal rocker arm; the horizontal rocker arm is fixedly connected with a vertical pivot; the vertical pivot is fixedly connected with the stator blades of the powder concentrator; the vertical pivot is rotationally connected with the powder concentrator shell; an inner ring of the annular driving disc is in friction connection with at least three guide wheels which are uniformly distributed; the guide wheels are arranged on the powder concentrator shell; an outer ring of the annular driving disc is meshed with two driving gears which are symmetrically arranged; each driving gear is provided with a driving mechanism; the driving mechanism is arranged on the powder concentrator shell; the pin shaft is a stepped shaft; and the annular driving disc is supported on a shaft shoulder of the pin shaft. According to the device, the stator blade distance can be automatically adjusted according different material grindabiliies and different finished product requirements.

Description

technical field [0001] The invention relates to a vertical roller mill powder separator, in particular to an automatic adjustment device for the distance between stationary blades of the vertical roller mill powder separator. Background technique [0002] The vertical mill integrates crushing, drying, grinding, and grading conveying in one, with high production efficiency, and can grind block, granular and powder raw materials into required powder materials. [0003] The vertical mill system includes the main transmission device, grinding disc device, lubrication device, hydraulic device, powder selection device, etc. The powder classifier classifies the pulverized materials brought up by the gas through the stationary blades of the powder classifier, and screens out the fine powder that meets the product fineness requirements. In order to meet the adaptability of the vertical mill to various materials and control the finished products with different fineness, the spacing o...

AI Technical Summary

Problems solved by technology

At present, the spacing of the stationary blades of some mills is fixed and cannot be adjusted, which greatly reduces the adaptability of the vertical mill to the grinding materials.

The static blades of some powder classifiers can be adjusted, but it can only be completed by the operator after the vertical mill system is shut down, that is, the adjustment of the spacing of the static blades is still in the manual stage.

Manually adjusting the spacing of the stator blades seriously affects the automation of the vertical mill, and greatly reduces the equipment operation rate of the vertical mill
