Description

Technical Field

[0001] The utility model relates to the field of garbage disposal, in particular to a multi-stage screening device for domestic garbage. Background Art

[0002] People generate a lot of garbage in their daily lives. In the past, these domestic garbage were either transported to power plants for incineration to generate electricity, or buried in the land. As time went by, people gradually realized that the garbage buried in the land not only polluted the environment, but also destroyed the ecology. For sustainable development, people began to classify the garbage and recycle the usable parts, reducing the pollution to the environment. Now the garbage is generally transported to the garbage treatment plant for screening before being processed. Among people's domestic garbage, some garbage often piles up together and carries a lot of water. Excessive water will make it easier for microorganisms in the garbage to reproduce and grow, which will accelerate the corruption of the garbage, causing the garbage to pile up and stick together, affecting the operator's screening of the garbage. For this reason, a multi-stage screening device for domestic garbage is proposed. Utility Model Content
