Automatic sorting and crushing device for waste

Abstract

The invention relates to the technical field of waste processing equipment and particularly relates to an automatic sorting and crushing device for waste. The automatic sorting and crushing device comprises a feeding hopper, a material sorting tank and a crushing tank, wherein a coarse filtration pipe, a fine material pipe and a sieving mechanism are respectively arranged in the material distribution tank, a coarse material crushing chamber and a fine material crushing chamber are formed in the crushing tank in parallel, a crushing paired roll and a fine crushing mechanism are arranged in thecoarse material crushing chamber, and a crushing pipe and a screw rod extrusion mechanism are respectively arranged in the fine material crushing chamber. According to the crushing device, materials falling from the feeding hopper are sorted by virtue of the sieving mechanism in the material sorting tank, coarse materials are sequentially and respectively crushed by virtue of the crushing paired roll and a crushing shaft in the coarse material crushing chamber, and fine materials are sequentially and respectively crushed by virtue of a crushing rotating roll and the screw rod extrusion mechanism in the fine material crushing chamber, so that the automatic sorting and crushing process of waste with different particle sizes is realized, the particle sizes of the crushed waste are uniform, and the convenience of the subsequent waste treatment is improved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment equipment, in particular to a garbage automatic classification and crushing device. Background technique [0002] Garbage is unwanted or useless solid and fluid matter. In densely populated cities, garbage disposal is a headache. Common way is to send to landfill after collecting for landfill treatment, or burn with incinerator. But both create environmental concerns, and ending overconsumption could further reduce landfill saturation. Waste disposal in landfills not only pollutes the groundwater and emits a bad smell, but many cities have less and less landfill area. Incineration inevitably produces toxic gases that harm living organisms. Most cities are researching ways to reduce waste and encourage recycling. At present, when the garbage is processed, it must first be crushed. The existing general garbage crushing device simply crushes the garbage. During the crushing process, it...

Problems solved by technology

At present, when the garbage is processed, it must first be pulverized. The existing general garbage pulverization device simply pulverizes the garbage. During the pulverization process, the garbage with different particle sizes cannot be classified, and the pulverization effect is poor.
