Description

Kitchen waste macro-aggregate is sorting unit in advance

Technical Field

The application relates to the field of kitchen waste pretreatment, in particular to a kitchen waste macro-material pre-sorting device.

Background

At present, the component characteristics of the kitchen waste raw materials are determined by the dietary habits and living habits of groups and subsequent storage, collection and transportation systems, and compared with foreign kitchen waste, the domestic kitchen waste is greatly different. The main characteristics are as follows: 1. the water content is high and reaches 75-85%; 2. the organic matter content accounts for 75-90% of the dry weight, and a large amount of biomass energy is contained; 3. the grease content is high and reaches 1.5-3%; 4. the components are complex, and the material contains mixed plastics and large interferents such as large tablecloth, large woven bags and the like (hereinafter collectively referred to as large materials). The large materials of the kitchen waste raw materials are easy to cause the problems of blockage, winding and the like in the material conveying process of a treatment system.

Chinese patent No. CN205518951U discloses a device for pre-sorting large kitchen waste materials, which comprises a hopper, a large material pre-sorting mechanism arranged on the feeding side of the upper part of the hopper, a double-screw conveyor on the lower part of the hopper, a liquid collecting tank and a gas collecting hood fixed on the top of the hopper.
