Description

Kitchen garbage screening is clear machine just

Technical Field

The utility model relates to a kitchen garbage pre treatment facility especially relates to a kitchen garbage screening is clear machine just.

Background

In order to respond to the disputes of national call to carry out waste classification in various big cities, the problem of recycling treatment and disposal of urban wet waste represented by kitchen waste after classification is urgently to be solved. After the kitchen waste is collected and transported, the kitchen waste is primarily sorted, large impurities (such as plastic packaging bags, glass products, plastic bottles and the like) in the kitchen waste are removed, the kitchen waste enters a crushing, sorting and pulping link, and the high organic matter slurry enters an anaerobic fermentation system after oil extraction to produce methane for recycling.

However, the kitchen waste has complex components and contains a large amount of inorganic substances such as plastic bags, woven bags, plastic bottles, glass bottles, shells, gravels, glass and the like, and therefore, the equipment for primary screening and cleaning of the kitchen waste before pretreatment is particularly important. The cleaning efficiency and the cleaning quality of the equipment determine the organic matter loss rate of the pretreatment system and the normal operation of subsequent equipment.

Patent publication No. CN207446416U discloses a kitchen garbage drum screening machine of area heating.
