Abstract
Description
Technical Field
[0001] The utility model relates to the field of garbage sorting and conveying, in particular to a mixed material conveyor used for garbage sorting. Background Art
[0002] With the increasing urbanization and industrialization, resources are becoming increasingly scarce, while waste, such as construction and renovation waste, electronic product waste, industrial waste, domestic waste, and kitchen waste, is increasing. Waste is also a large amount of recyclable resources. Therefore, the country has vigorously promoted waste sorting and recycling systems. The recycled waste is processed by coarse crushing equipment to form a mixture of small-sized solids, lightweight materials (films, small flakes, etc.), and dust. The mixture is then transported by conveyors to various reprocessing units or sorting units for classification. The disadvantages of this system are: first, the mixture generates excessive dust during transportation, creating a harsh working environment and seriously damaging the health of workers. Therefore, it is necessary to remove the dust from the mixture; second, the dust mixed in the mixture is heavy, which increases the overall transportation load and energy consumption, reduces transportation efficiency, and reduces sorting efficiency; third, the dust enters the machinery, increasing machine wear and shortening its service life, and increasing the failure rate of sorting equipment and other equipment.
