Technical Field

The invention belongs to the field of kitchen waste treatment and recycling, and particularly relates to a kitchen waste dry-wet separator.

Background

The kitchen waste occupies a large proportion in the existing solid waste in China, compared with other plastic and rubber organic solid wastes, the kitchen waste has the characteristics of high water content, high viscosity, complex property and the like, and is easy to stick to a draining net during extrusion to block the draining net, so that extrusion equipment cannot continue to work. In the existing dry-wet separator, a solid-liquid separator is mainly used, the solid-liquid separator can be used for treating the preliminary separation of solid and liquid, the water content of the treated kitchen waste is still high, the operation such as airing and drying is needed, the airing occupied area is large, the pollution is serious, the drying cost is high, and the environment pollution is large due to the fact that other substances are contained in the dried steam.

Aiming at the problems of the dry-wet separator, the solution in the prior art is that an open type variable-pitch variable-root-depth single-blade spiral conveying dry is generally used in the extrusion section of the extrusion spiral part, and the water filter screen is designed to be in a step type, for example, the dry-wet separator disclosed in patent 201920185815.X, the dry-wet separation device of the kitchen waste achieves the dehydration effect through extrusion, and the water cannot be completely separated by the extrusion in the spiral stage. In addition, the volume, the quality and the like of each component of the kitchen waste are basically different, the effect of complete separation cannot be achieved by virtue of the water separated by the kitchen waste in the spiral extrusion stage, and the consequences that a draining net is blocked and cannot be utilized are caused. And the structure of the open type pitch-variable and root-variable single-blade spiral conveying dry and step type water filtering net is relatively complex, and the assembly and the cleaning are relatively troublesome, if the above consequences are caused, some economic and energy losses or consumption can be caused, and in comparison, the dry-wet separator which has a simple structure and is provided with an additional water draining net cleaning device is more suitable for treating the kitchen waste.
