Technical Field
The utility model relates to a feeder sight glass belongs to feeder equipment technical field.
Background
At present, a coal feeder is a device for uniformly and continuously supplying raw coal to a coal mill, which can automatically adjust the coal feeding amount according to the change of the load demand of the coal mill, complete the measurement of the coal feeding amount in the conveying process, and display the instantaneous value and the accumulated value of the coal feeding amount.
The CS2036HP type electronic weighing type coal feeder of jian power plant use shanghai power generation equipment complete set design institute production of jian, and every boiler is equipped with 6 coal feeders, and 1 coal feeder corresponds 1 coal pulverizer, and coal feeder equipment limit contains entry coal breakage flashboard, entry pipeline, coal feeder export flashboard, to pipeline and relevant controller, measurement station, cable etc. between the coal pulverizer telescopic joint.
Unlike the viewing windows of other devices, the coal feeder is transported by the coal feeder. The coal dust can be attached to the surface of the observation window to influence the visual effect. The dust cleaning device for the old coal feeder adopts a wiper type scraper device to be arranged at the outer sides of an end door and a side door to clean coal dust attached to the surface of glass, but because the end door and the side door of the coal feeder adopt explosion-proof structures which are relatively thick and heavy, the coal dust cleaned from an observation window can still be accumulated on a step between the observation glass and a window seat. Moreover, the observation window needs manual scraping, and in the practical situation, under the normal operation condition of the equipment, a user rarely scrapes the window regularly, so that coal on the window glass is accumulated more and more thickly, and the scraping difficulty is increased. In the past, the accumulated coal powder is harder and harder, so that the windscreen wiper is difficult to rotate to achieve the effect of cleaning accumulated coal, and operators are difficult to observe the running condition of a belt in the coal feeder.
In view of the above-mentioned drawbacks, the present designer actively makes research and innovation to create a sight glass for coal feeder, so that the sight glass has industrial value.
