A guide vane angle adjustment system related to a powder classifier

Abstract

The invention relates to the field of material screening technology. Specifically, it is an angle adjustment system for guide blades of a powder classifier. A flange is provided at the bottom of a stepper motor with a brake disc. A powder classifier housing is installed on the flange. The stepper motor The output end is equipped with a reducer with a transmission gear. The large ring gear supported by the bracket on the powder separator casing is paired with the transmission gear. The other end of the large ring gear is connected to the transmission arm on the guide blade and the limit switch is installed on the selector. The powder machine housing is distributed on both sides of the transmission arm, and the displacement sensor is installed on the powder separator housing and distributed on one side of the transmission arm. The advantage of the invention is that: due to the use of an electric actuator, the degree of automation of the guide blade angle adjustment of the powder separator is greatly improved, real-time adjustment of the guide blade angle is realized, the powder selection performance of the powder separator is maximized, and the powder selector is improved. The output of the powder separator greatly shortens the debugging time of the powder separator, saves a lot of unnecessary labor costs, and greatly improves the economic benefits of the production enterprise.

Description

[0001] [technical field] [0002] The present invention relates to the technical field of material screening, in particular to the adjustment of the blades of the coal dust static classifier with high fineness, the angle of the guide vane of the dynamic and static combined state classifier for raw meal, clinker mill and blast furnace slag mill. Regulate the system. [0003] [Background technique] [0004] Separators are widely used in coal mills, raw meal unloading drying mills and cement mill systems in new dry process cement production lines. At present, the guide blades of the classifiers used in coal mills, slag mills, raw meal mills, and cement mills all use guide vane adjustment systems to adjust their powder selection angles. There are two main adjustment methods: single-chip adjustment, and multi-chip associated multi-group manual adjustment. However, the above two adjustment methods have their own shortcomings. Single-piece adjustment is time-consuming, and it takes...
