Description

Technical Field

[0001] The utility model relates to the technical field of waste incineration slag screening, in particular to an anti-blocking type drum screening device for treating slag in a waste incineration power plant. Background Art

[0002] Incineration is a method of waste disposal that converts waste into ash and gas through high-temperature combustion, reducing its volume and recovering energy. This method is widely used in modern cities, helping to reduce land pressure, prevent groundwater contamination, and reduce greenhouse gas emissions.

[0003] However, in the existing technology, the screen mesh of the drum screening machine is easily clogged by wet garbage when passing through it, resulting in a decrease in screening efficiency. In order to maintain the normal operation and high efficiency of the screening machine, it is usually necessary to stop the machine regularly for cleaning to remove the clogged screen mesh. However, this frequent shutdown and cleaning not only interrupts the normal production process, but also leads to a decrease in production efficiency. At the same time, the additional manpower and time required to perform these cleaning tasks will also increase production costs accordingly. Therefore, we provide a non-clogging drum screening device for waste incineration power plant slag treatment. Utility Model Content
