Totally-closed automatic crushing and sorting technical device of domestic garbage and resource-based product production

Abstract

The invention relates to a totally-closed automatic crushing and sorting technical device of domestic garbage and resource-based product production, which effectively solve the key technical problems of the crushing and the sorting of the domestic garbage and the resource-based product production. The technical device is provided with the following parts: a domestic garbage mixing and coarse crushing device (capable of being applied to crushing large-size domestic garbage) consisting of an energy storage belt pulley, a speed changer, a rotor, a movable cutter head, a fixed cutter platform, a transmission gear and a conveying mechanism; a domestic garbage mixing and fine crushing device provided with a coarse crushing chamber, an intermediate crushing chamber, a fine crushing chamber and a discharging chamber consisting of turntables, detents, rails and screens; and a garbage automatic sorting device comprising a four-stage sizing mechanism consisting of a rotary drum, an impacting head and an arc screen, and a plastic removal separating mechanism consisting of vibrating boards. The totally-closed automatic crushing and sorting technical device is operated automatically in a totally closed mode, can simply sort the domestic garbage into three types of metal, plastic and organic-inorganic mixed sandy mud after mixing and crushing the domestic garbage, and uses market mature technical devices to produce resource-based products respectively. The totally-closed automatic crushing and sorting technical device has the advantages of unique structure, reliable product quality and the like.

Description

Technical field: [0001] The invention belongs to fully enclosed automatic crushing and sorting technical equipment for domestic garbage and the production of resource-based products. Background technique: [0002] At present, due to the complex composition of domestic waste and the influence of factors such as high moisture content in domestic and foreign classification and treatment technologies for municipal solid waste, it is difficult to realize automatic crushing and classification. Even in developed countries, only the process of sorting by conveyor belt and manual , and then recycled separately, the workers' working environment and sanitation conditions are poor, and the cost of the sorted usable waste is high, which is not conducive to commercial operation and affects the recycling of waste resources. The crushing treatment of garbage can only be carried out after sorting. For example: the garbage pretreatment and sorting system of Shengong Environmental Engineering ...

Problems solved by technology

[0002] At present, due to the complex composition of domestic waste and the influence of factors such as high moisture content in domestic and foreign classification and treatment technologies for municipal solid waste, it is difficult to realize automatic crushing and classification. Even in developed countries, only the process of sorting by conveyor belt and manual , and then recycled separately, the workers’ working environment and sanitation conditions are poor, and the cost of the sorted usable waste is high, which is not conducive to commercial operation, which affects the recycling of waste resources.

The crushing treatment of garbage can only be carried out after sorting. For example: the garbage pretreatment and sorting system of Shengong Environmental Engineering Co., Ltd. of China Academy of Sciences, the domestic garbage resources of Lishan Company of Siping City, Jilin Province and the Environmental Equipment Research Center of Agricultural Machinery Institute The chemical treatment system, the classification technology of Beijing Zhongyi Huaneng Environmental Protection Technology Co., Ltd., etc. In addition, the water separation technology system of Shenzhen Lvnuo Environmental Protection Technology Co., Ltd. uses the different proportions of sieved garbage and garbage to separate multiple times in the classified waterway , the garbage that cannot be separated still needs to be landfilled, the water and electricity consumption is huge, the operating cost is high, and the classification effect is poor

For the crushing of large domestic waste and the fine crushing equipment of waste, there are also disadvantages such as large energy consumption and large particle size of waste after fine crushing. For example, the large waste crusher produced by Swiss SID company has high energy consumption and a processing capacity of 10-20t. / h equipment, installed power 200KW

Garbage fine shredders have a processing capacity of 2-20t / h, equipment with a crushing particle size of 8-80mm, and installed power of 160-250KW. There is still no technical solution for terminal products for crushed garbage
