Kitchen waste crushing system and method

Abstract

The invention discloses a kitchen waste crushing system and method. The system comprises a treatment area, a dehydration area and a winnowing classification area which are sequentially connected from top to bottom, wherein a feed port I and an air inlet I are formed in the top end and the side surface of the treatment area respectively, the air inlet I and a blower device I outside the treatment device are communicated, a plurality of needling devices are staggered on the inner wall of the treatment area, and an active sludge spray device is arranged in the position close to the feed port I. The kitchen waste crushing system comprises three parts, namely, the treatment area, the dehydration area and the winnowing classification area, primary waste crushing is realized through repeated operation of the needling devices and the blower device in the treatment area, the waste is treated with active sludge, the treatment is economic and environment-friendly, then the waste is dehydrated, later transportation is facilitated, and the sterilization effect is realized; finally, winnowing classification is performed, and the kitchen waste after the crushing treatment can be conveniently transported to a waste treatment plant for further treatment.

Description

technical field [0001] The invention relates to a garbage crushing system, in particular to a kitchen garbage crushing system and method. It belongs to the technical field of environmental protection equipment. Background technique [0002] Two-thirds of China's cities are surrounded by garbage, and one-quarter has no landfill sites. Correspondingly, the urban garbage disposal rate is only about 50%, and the garbage is approaching the urban circle step by step. Like poisonous water, it seeps into the lives of urbanites. Sorting and reusing waste as a resource is a waste disposal method advocated internationally, but due to historical problems and perennial living habits in China at this stage, it is still difficult to realize it for a while. [0003] Among all kinds of waste, the treatment of kitchen waste is particularly difficult. Behind all kinds of delicious domestic dishes are countless garbage. Due to the lack of basic classification habits, food waste is often extr...

AI Technical Summary

Problems solved by technology

Behind all kinds of delicious domestic dishes are countless garbage. Due to the lack of basic classification habits, food waste is often extremely complicated, and its contents include leftovers (including vegetable leaves, shells, bones, etc.), leftovers, waste paper, waste Rags, plastic bags, and even broken tableware, etc., are high in oil content, generally greasy, high in protein content, and have a lot of soup and water, which are easy to rot and deteriorate, high collection and transportation costs, and difficult to handle

[0004] At present, large-scale centralized treatment stations are used for the treatment of food waste, which requires a large number of transportation vehicles, which brings traffic pressure to the increasingly congested traffic in the city; in addition, toxins are easy to be produced during transportation, and food waste is easy to rot and smell. The food waste has deteriorated and smelly, and when it is transported to the waste treatment plant, the food waste has produced a large amount of toxins
