Description

Technical Field

[0002] Solid waste refers to solid, semi-solid, and gaseous items and materials placed in containers that have lost their original use value or have not lost their use value but have been discarded or abandoned during production, life and other activities, as well as items and materials that are included in waste management according to laws and administrative regulations. Because most of them are more harmful, they are generally included in the solid waste management system, such as stones with small particles that are difficult to classify.

The existing solid waste treatment device only performs simple screening of solid waste. For example, the patent application with application number CN202011302607.7 discloses the use of screening solid waste and using atomization to reduce dust treatment. Although the impact of solid waste on the environment during treatment is reduced to a certain extent, there is still a situation where solid waste remains on the screening structure inside the device after long-term use of the solid waste treatment device, resulting in secondary mixed pollution.
