Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solid-liquid separation, in particular to a kitchen waste solid-liquid separation air flotation device. Background Technique
[0002] Kitchen waste refers to the waste generated in activities such as residents' daily life, food processing, food service, and unit meal supply. Kitchen waste generally contains extremely high moisture and organic matter and is prone to spoilage. When dealing with kitchen waste, it is necessary to first carry out solid-liquid separation treatment on the kitchen waste. Traditional kitchen waste solid-liquid separation methods often have the problem of incomplete solid-liquid separation. A patent document with the publication number CN 214763658 U records a kitchen waste solid-liquid separation device. The device includes a storage tank. A separation net is horizontally and fixedly connected inside the storage tank. One end of the separation net and the side wall of the storage tank are provided with solid separation holes.
