Description

Technical Field

[0001] The utility model relates to a light garbage stripping device of a garbage screening system. Background Art

[0002] The traditional garbage screening process mainly uses a drum screen to separate large materials and fine materials (mainly humus). The garbage screening system corresponding to the treatment process includes a plate feeder, a leveler, a drum screen, a wind separator and a baler arranged in sequence. The garbage on the leveler is manually sorted to separate oversized fabrics and bricks; the undersize of the drum screen is humus; the oversize of the drum screen is separated into light materials and heavy materials by a wind separator. The light materials are sent to the baler to form combustibles, and the heavy materials are transported to the magnetic separator, which separates metals and inorganic aggregates.

[0003] Normally, the water content in landfill waste is relatively high. When the waste materials with high water content are rolling inside the drum screening machine, it is easy for mud and plastic waste to stick together, and mud, aggregate (stone waste) and plastic waste to stick together. Both of the above situations are not conducive to the separation of the three main screened materials: humus, inorganic aggregate, and light combustible waste. If the plastic content in the humus is too high, it will directly affect the visual quality and even the test report of the humus, directly affect the test results, and cause rework, increased difficulty in humus disposal and other problems, affecting production efficiency. The inorganic aggregate (stone waste) separated by the magnetic separator is usually used for backfilling of surrounding mountains. If the aggregate and plastic waste are severely bonded, there will be a similar situation as humus. Utility Model Content
