Description

TECHNICAL FIELD

[0001] The utility model relates to the field of slag extractor, especially relates to the rotary locking mechanism for the slag extractor. BACKGROUND

[0002] The boiler is the indispensable heating device in industrial production, and most of the boilers are heated by burning coal. The coal will produce slag after burning. If the completely burned slag in the boiler is not discharged in time, it will seriously affect the combustion efficiency of the coal in the furnace, because the slag will occupy a large amount of space in the furnace, resulting in the lack of oxygen in the furnace, which will cause the coal in the furnace to burn insufficiently, so it is necessary to use the slag extractor to discharge the slag in the boiler.

[0003] The patent with the patent name of "a boiler slag extractor" (the patent application number is 201521113390.X) discloses a slag extractor. The spiral blade arranged in the boiler can discharge the coal slag from the inside of the boiler. Finally, the coal slag falls into the trolley, and the slag discharge efficiency is high. However, when the slag extractor discharges the coal slag, the worker needs to check the coal slag storage capacity in the trolley regularly. Once the worker forgets to check the coal slag storage capacity in the trolley due to being busy with other things, the coal slag may overflow the trolley and fall to the ground, so manual cleaning is needed, which will increase the labor of the worker. Therefore, it is necessary to propose the rotary locking mechanism for the slag extractor to solve the above problems. UTILITY MODEL CONTENT
