Urban waste classified recovery device for municipal engineering

Abstract

The invention discloses an urban waste classified recovery device for municipal engineering. The urban waste classified recovery device comprises a first box body and a second box body, wherein a feeding opening is formed in the top of the first box body, and a filtering plate is arranged below the feeding opening; a material receiving box is arranged at the bottom of the first box body, a first supporting plate is arranged on the inner wall of the first box body, and a first driving motor used for driving the first supporting plate to be matched is arranged on the side wall of the first box body; and a scraper matched with the filtering plate is arranged in the first box body, a first opening is formed in the side wall of the first box body, and clear water is contained in the second boxbody. Filtered objects are screened under the buoyancy effect of the clear water, so that disposable chopsticks and plastic bags float on the water surface, bones, metal and other garbage are precipitated at the bottom of the second box body, therefore the disposable chopsticks and the plastic bags are directly collected, the garbage screening difficulty is reduced, and garbage screening is more convenient.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to an urban waste sorting and recycling device for municipal engineering. Background technique [0002] Food waste is the most important type of urban waste, including food processing leftovers (kitchen waste) and food residues (swill) produced by families, schools, canteens, and catering industries. Its composition is complex, which is a mixture of oil, water, fruit peel, vegetables, rice noodles, fish, meat, bones, waste tableware, plastic, paper towels and other substances. The amount of food waste in my country is very large, and it is showing a rapid upward trend. [0003] The use of composting technology to treat food waste is one of the methods of food waste treatment. The waste has to go through several stages of collection, screening, dehydration, fermented composting and post-composting treatment. During the screening process, the waste mainly uses d...

Problems solved by technology

[0003] The use of composting technology to treat food waste is one of the methods of food waste treatment. The waste has to go through several links such as collection, screening, dehydration, fermented composting and post-composting treatment. During the screening process, the waste mainly uses disposable chopsticks , plastic bags, bones, etc., but disposable chopsticks and other garbage can be recycled. The existing recycling methods generally use manual selection. At the same time, plastic bags cannot be directly used for landfill. They also need to be picked out and manually selected. The method requires workers to directly dig through the garbage, and the sanitation environment is poor, which will have a certain impact on human health
