Automatic sorting treatment system for kitchen waste and treatment process

Abstract

The invention discloses an automatic sorting treatment system for kitchen waste and a treatment process, relates to the field of domestic waste treatment, and solves the problems that existing kitchenwaste is large in reserve and threatens human health. The automatic sorting treatment system comprises a transport vehicle, a material collecting bin, a water filtering elevator, a large-foreign matter sorting machine, a fine crushing and sorting machine, an extrusion dehydrator, an oil-water separation device, a secondary pendulum bob pulping machine and an anaerobic fermentation tank, wherein the water filtering elevator is used for receiving the kitchen waste uniformly conveyed by the material collecting bin and carrying out water filtering treatment; the large-foreign matter sorting machine is used for sorting large foreign matters in the kitchen waste residues; the fine crushing and sorting machine is used for carrying out fine crushing on the large sorted kitchen waste residues andsorting out inorganic impurities; the extrusion dehydrator is used for carrying out extrusion dehydration treatment on the finely sorted kitchen waste residues; the oil-water separation device is usedfor mixing kitchen waste swill obtained after water filtration and kitchen waste slurry obtained after extrusion dehydration and then carrying out oil extraction and dehydration treatment; the secondary pendulum bob pulping machine is used for finely pulping the kitchen waste residues subjected to oil extraction and dehydration; and the anaerobic fermentation tank is used for carrying out anaerobic fermentation on kitchen waste liquid subjected to oil extraction and dehydration. The automatic sorting treatment system is high in treatment efficiency, good in treatment effect, energy-saving andenvironmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to an automatic sorting and treatment system and a treatment process for kitchen waste. Background technique [0002] Kitchen waste, namely kitchen waste, also becomes swill or slop, which is the domestic waste formed by people in the process of production and consumption. Food waste is easily corrupted and deteriorated, which emits a bad smell and spreads bacteria and viruses. [0003] According to different sources of food waste, it is mainly divided into food waste and kitchen waste. Catering waste mainly comes from the leftovers of the catering industry such as restaurants and canteens. This kind of waste is relatively large, has a wide range of sources, and is widely distributed. Kitchen waste mainly comes from the leftovers discarded in the daily cooking of residents, and the amount is not as large as dining waste. The main characteristics of kitchen waste ...
