[0002] Boilers are indispensable heating devices in industrial production. Most boilers provide heat by burning coal. Coal will produce slag after combustion. If the 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 a lack of oxygen in the furnace, which will cause incomplete combustion of the coal in the furnace.

The slag removal mechanism has the crushing and filtering effects, so that the slag removal The mechanism crushes the coal slag, and the crushed coal slag ash is collected and processed for subsequent recycling. At the same time, the incompletely crushed coal slag can be filtered by the filter screen on the slag removal mechanism, which effectively realizes the slag removal of the coal slag produced by boiler combustion. However, there are still some problems in the use of this device. That is, in the process of the slag falling from the boiler to the discharge hopper, some slag will adhere to the inner wall of the boiler. Because it is not scraped off, the slag will accumulate in the boiler for a long time, which makes it easy for the slag to gather together each time. For this reason, we proposed a boiler slag removal mechanism for a heating station to solve the above problems. Utility Model Content
