Description

Technical Field

[0001] This utility model belongs to the field of kitchen waste treatment technology, and in particular relates to a solid-liquid separation device for kitchen waste treatment. Background Technology

[0002] Solid-liquid separation is a key step in food waste treatment, aiming to separate solid matter (such as food scraps) from liquids (such as oil and water) in organic waste for subsequent treatment (such as composting, anaerobic fermentation, or direct discharge).

[0003] Traditional kitchen waste solid-liquid separation equipment typically uses filter plates to separate solids and liquids. This method can only separate relatively obvious liquids, but it is difficult to effectively separate the moisture in solid waste. As a result, a large amount of moisture still remains in the solid waste after the separation process, requiring the replacement of other separation equipment to process the solid waste again. This not only increases the number of operation steps, but also increases the waste treatment cost. Utility Model Content

[0004] The purpose of this invention is to provide a solid-liquid separation device for kitchen waste treatment. Specifically, by setting up a separation mechanism, a motor drives a gear to rotate counterclockwise, which in turn drives a separation cylinder to rotate clockwise via a gear ring. When the waste enters the separation cylinder, centrifugal force separates the water from the waste, achieving a good solid-liquid separation effect and significantly reducing the moisture content of the solid waste. The solid waste in the separation cylinder is then conveyed to the right by spiral blades and discharged into a collection box. This method can significantly reduce waste treatment costs and solves the problem of traditional kitchen waste solid-liquid separation equipment, which typically uses filter plates for solid-liquid separation. This method can only effectively separate relatively obvious liquids, but it is difficult to effectively separate the moisture in the solid waste.
