Raw refuse sorting process

Abstract

The invention relates to a raw refuse sorting process. The raw refuse sorting process includes the following steps that raw refuse is transported into a material bin; the refuse in the material bin isconveyed to a bag breaking device to be subjected to bag breaking treatment; the refuse after being subjected to bag breaking treatment is conveyed to a building waste sorting system, and stone, glass and metal in the refuse are separated out; the refuse with the stone, the glass and the metal separated out is conveyed to a breaker, breaking and dust screening are performed, and the dust after screening treatment is used for compost; and the refuse after being broken is conveyed to a sorting system, and classified collecting is performed. Totally, the raw refuse sorting process is reasonablein design, and has the beneficial effects of being exquisite in classifying, high in screening efficiency, high in plastic substance reutilizing rate and environment-friendly and harmless.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to a raw garbage sorting process. Background technique [0002] The status quo of China's urban domestic garbage pollution is a status quo. With the development of the economy and the improvement of people's living standards, the problem of garbage has become increasingly prominent. 2 / 3 of the 668 cities in China are surrounded by garbage belts. These garbage cannot be buried. Burning is too much to burn, causing a series of serious hazards; according to the investigation of waste expert Wang Weiping, the potential of waste resources is also increasing with the development of living standards and economy. Among the waste components, metal, paper, plastic and glass are regarded as It is a resource that can be directly recycled, accounting for 42.9% of the total garbage, and the direct recycling rate should not be lower than 33%. However, this requires the country ...

[0002] The status quo of China's urban domestic garbage pollution is a status quo. With the development of the economy and the improvement of people's living standards, the problem of garbage has become increasingly prominent. 2 / 3 of the 668 cities in China are surrounded by garbage belts. These garbage cannot be buried. Burning is too much to burn, causing a series of serious hazards; according to the investigation of waste expert Wang Weiping, the potential of waste resources is also increasing with the development of living standards and economy. Among the waste components, metal, paper, plastic and glass are regarded as It is a resource that can be directly recycled, accounting for 42.9% of the total garbage, and the direct recycling rate should not be lower than 33%. However, this requires the country to spend a lot of money to clean up. Through manual methods, large plastic, paper, and metal materials in domestic waste are screened for recycling and reuse. This kind of waste treatment method is not conducive to environmental protection, the waste reuse rate is low, and the garbage sorting effect is poor. The plastic substances in the garbage cannot be fully utilized; therefore, it is necessary to provide a primary garbage sorting process with fine classification, high screening efficiency, high recycling rate of plastic substances, and environmental protection and harmlessness
