Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a stepless self-adjusting spiral unloading device used on a vertical centrifuge. Background Art

[0002] The spiral discharge device is a device used in the centrifuge to scrape off the coal particles left on the inner wall of the screen basket under the action of centrifugal force. When the coal particles are continuously scraped off, the spiral discharge rotor on the spiral discharge device will also be continuously worn. After the spiral discharge rotor is worn, the gap between the blades of the spiral discharge rotor and the inner wall of the screen basket will continue to increase, resulting in the coal particles on the inner wall of the screen basket cannot be scraped off in time, affecting the life of the screen basket and reducing the product yield.

[0003] After the gap between the blades of the spiral unloading rotor and the inner wall of the screen basket becomes larger, the spiral unloading rotor needs to be adjusted. The adjustment of the spiral unloading rotor in the existing bolt unloading device is complicated and cumbersome. It is necessary to remove the screen basket, the feeding plate, the mounting pad, and the spiral unloading rotor in sequence. After the removal, the mounting pad previously installed on the top of the spiral unloading rotor is installed to the bottom of the spiral unloading rotor, and then the components are installed in sequence. The method of this process is very cumbersome, requiring the disassembly and installation of a large number of bolts, which takes a lot of time. In addition, for every 1mm increase in the height of the adjustment pad, the gap decreases by 0.34mm. There is a position limit for the adjustment of the spiral unloading rotor, and it cannot be directly adjusted to the appropriate position. It requires workers to make multiple adjustments, which wastes a lot of manpower and material resources, and the site may not have a good adjustment environment. There is a need for a spiral unloading device that can be easily disassembled, is not restricted by the environment, and is easy to adjust steplessly. Utility Model Content
