Kitchen waste composting barrel

Abstract

The invention discloses a kitchen waste composting barrel. The kitchen waste composting barrel comprises a barrel body and a barrel lid, wherein the barrel body is internally provided with a water filtering board; the circumferential outer side of the water filtering board is in contact with the barrel wall of the barrel body; the water filtering board divides the barrel body into a composting area and a filtered water collecting area; a plurality of grooves are formed in the inner side of the barrel wall; a mesh plate is arranged at the outer surface of each groove; the mesh plates and the grooves form vertical cavities; the cavities are communicated with the filtered water collecting area; the bottom surface of the inner wall of the barrel lid is inclined or curved; the lowest end of thebottom surface of the inner wall of the barrel lid corresponds to one of the cavities and import condensed water formed on the inner wall of the barrel lid into the cavity through a collecting plate;and an intake valve and an exhaust valve are fixed on the barrel body. The condensed water on the barrel lid is collected at the lowest end of the bottom surface of the inner wall of the barrel lid,so that the outflow of the condensed water in the composting barrel is facilitated, and the humidity in the composting body can be changed by collecting the condensed water; and in addition, the air flow in the composting body can be adjusted through the intake valve and the exhaust valve.

Description

technical field [0001] The invention relates to a compost bucket, in particular to a compost bucket used for kitchen waste, and belongs to the technology in the field of garbage treatment. Background technique [0002] The main sources of kitchen waste are household kitchens, restaurants, restaurants, cafeterias, markets and other food processing-related industries. At present, 40% of the vast majority of urban waste in the world is kitchen waste, mainly including discarded vegetable leaves, leftovers, etc. Vegetables, leftovers, fruit peels, eggshells, tea dregs, bones, etc. Its chemical components are mainly starch, cellulose, protein, lipid and inorganic salts. Kitchen waste has the following characteristics: First, the content of organic matter such as crude protein and crude fiber is high, and kitchen waste is rich in nitrogen, phosphorus, potassium, calcium and various trace elements, which has great development and utilization value, but is perishable and produces st...

Problems solved by technology

[0003] Composting is a rather complicated process, currently mainly aerobic composting and anaerobic composting, however, aerobic composting requires ventilation and exhaust, which is an exothermic reaction, and the temperature of the compost often rises to 55-70 ℃, the odor is easy to diffuse during the process; the anaerobic reaction is usually carried out efficiently in three stages: normal temperature 20 ℃, medium temperature 35 ℃ and high temperature 55 ℃, so the reaction odor is less in a closed environment and it is not easy to spread, but anaerobic reaction The degradation of organic matter after the reaction is not complete, and aerobic fermentation is required for further degradation and stabilization; both composting methods have great disadvantages
