Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a drum screen for waste treatment. Background Technology

[0002] With the improvement of people's living standards, the number of daily necessities has gradually increased, leading to an increase in household waste. Waste disposal is a current challenge. Waste-to-energy generation can not only reduce waste accumulation, eliminate the spread of bacteria and infectious diseases, and reduce air pollution, but also generate a certain amount of electricity. The principles of waste disposal are harmlessness, reduction, and resource recovery. Waste incineration power generation greatly reduces landfilling, saving a large amount of land resources, and also reduces the air pollution of groundwater and the surrounding environment caused by landfills. Before waste incineration, in order to improve incineration efficiency, the waste needs to be crushed. To ensure that the crushed waste is of uniform size, a drum screen can be used to screen the crushed waste. Although the drum screens currently used for waste disposal can meet normal usage requirements, they still have shortcomings in actual use. For example, existing drum screens often require manual shovels to put the waste into the drum screen for screening, which is labor-intensive and requires improvement. Therefore, a drum screen machine for waste disposal is proposed. Utility Model Content
