[0002] Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, and turning it into residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment facilities to prevent heavy metals, organic pollutants, etc. from being discharged into the environmental medium again. Recycling the heat generated by waste incineration can achieve the purpose of waste resource utilization, and the existing waste incineration equipment can basically meet the daily use needs, but there are still some shortcomings that need to be improved.

[0003] The waste incineration devices used on the market tend to produce a large amount of slag during the incineration process, which requires a screening device to screen and classify. Most of the existing screening devices use a rotary screening drum, which can quickly screen the slag inside by shaking the screening drum back and forth. However, due to the overall strength considerations of the existing screening drum, the size of the feed port is usually designed to be smaller, resulting in a lot of time required to feed the slag, resulting in low work efficiency. For this reason, we propose a slag processing and screening device for waste incineration to solve the above problem. Utility Model Content
