Self-rotating blowing type ash removal device for observation window of coal feeder

Abstract

The invention discloses a self-rotating blowing type ash removal device for an observation window of a coal feeder. The device comprises a self-rotating blowing mechanism and a regulation and control air supply mechanism, the self-rotating blowing mechanism is rotatably arranged in the center of observation glass and comprises a blowing connecting shaft and a self-rotating blowing part, the self-rotating blowing part is rotatably connected with the blowing end of the blowing connecting shaft by arranging a rotating connecting part, an air guide cavity is formed in the center of the self-rotating blowing part, arc-shaped blowing guide holes are evenly distributed in the outer side of the air guide cavity, and the regulation and control air supply mechanism comprises an air supply guide pipe and a regulation and control valve. The device has the beneficial effects that the designed self-rotating blowing mechanism is combined with the regulation and control air supply mechanism, so that the powder accumulation probability in the observation window is almost zero, the coal feeder does not need to be stopped due to the powder accumulation problem or the damage of a scraping strip, and the loss of power generation in a plant caused by stopping the coal feeder due to small defects is effectively reduced. The device is reasonable in design structure, convenient to disassemble and assemble, low in maintenance amount and long in service life.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment for the observation window of a coal feeder, and more specifically, relates to a self-rotating purge type ash cleaning device for the observation window of a coal feeder. Background technique [0002] In order to facilitate the observation of the internal operation of the coal feeder, an observation window is designed on the front and rear door panels of the coal feeder. Since coal ash and pulverized coal will be generated when the coal feeder is conveying coal, due to the positive pressure inside the coal feeder, the Coal powder will inevitably be raised during coal powder, and coal powder will adhere to the glass surface of the observation window, which will affect the observation. The center of the existing observation window will be equipped with a manually rotatable scraper cleaner. There is fluff attached to the glass surface of the observation window, and the fluff attached to th...

AI Technical Summary

Problems solved by technology

Due to the poor internal environment of the coal feeder, it is easy to produce powder accumulation. After frequent rotation of the scraper for cleaning, it is easy to cause the scraper blade to jam or even be damaged. As a result, the powder accumulation near the observation glass cannot be cleaned in time, and the monitoring function of the inside of the coal feeder is lost. , to delay the timing of troubleshooting, it is necessary to stop the coal feeder for inspection and treatment

In addition, due to the limitation of the length of the scraper blade, the window sill connected to the observation window is an area that cannot be cleaned by the scraper blade, and the accumulation of coal dust will affect the observation. After the coal dust accumulates to a certain extent, it will affect the rotation of the scraper blade, and it is necessary to stop. The coal feeder was transported for cleaning, and the coal feeder was shut down due to minor problems, which affected the normal operation of the unit and caused a certain degree of economic loss

Moreover, in daily use, it is necessary to intermittently rotate the scraping teeth or hairs of the scraping blade to clean and replace the powder accumulation, so as to maintain a good cleanliness on the inner surface of the observation window glass, which requires a waste of manpower and material resources during operation, and the equipment structure is easy Damaged, often requires maintenance, short lifespan
