Comprehensive rubbish sorting technology and comprehensive rubbish sorting machine

Abstract

A comprehensive garbage sorting technology includes the steps of garbage grinding, bag breaking, magnetic separation, primary winnowing, two-grade sorting in a rotary screen and secondary winnowing. A comprehensive garbage sorting machine comprises a plate-type feeder, a garbage grinding and bag breaking machine and a magnetic separator are mounted in a feeding section and a discharging section of the plate-type feeder respectively, a first winnower and a first U-shaped belt conveyer are sequentially arranged below the discharging end of the plate-type feeder, the rotary screen comprising a first screening section and a second screening section is arranged at the rear end of the plate-type feeder, a first discharging hopper and a second discharging hopper are arranged below the first screening section and the second screening section of the rotary screen respectively, a second U-shaped belt conveyer and a third U-shaped belt conveyer are arranged below the two discharging hoppers respectively, a fourth U-shaped belt conveyer is arranged at the rear end of the rotary screen, and a second winnower is mounted below the discharging end of the rotary screen. The comprehensive garbage sorting technology and the comprehensive garbage sorting machine have the advantages that magnetic metal, building garbage, organic matters and the like in garbage can be sorted out step by step, thorough separation of various materials in household garbage is achieved, and recovery and utilization of useful materials are facilitated.

Description

technical field [0001] The invention relates to the technical field of domestic garbage treatment, in particular to a garbage comprehensive sorting process and a sorting machine. Background technique [0002] At present, there are many sorting methods for domestic waste, for example, the common ones are mechanical vibrating screening method, winnowing method and so on. Commonly used sorting equipment includes vibrating screens, drum screens, wind separators, etc. Some equipment sorts according to the specific gravity of the various components in the garbage, such as vibrating screens and air separators, and some equipment sorts according to the particle size of the components in the garbage, such as drum screens. Since domestic waste contains various components, such as organic waste such as leftovers, construction waste, metal waste, plastic product waste, quality product waste, etc., the existing sorting methods and sorting equipment cannot separate the various components...

AI Technical Summary

Problems solved by technology

Since domestic waste contains various components, such as organic waste such as leftovers, construction waste, metal waste, plastic product waste, quality product waste, etc., the existing sorting methods and sorting equipment cannot separate the various components in the waste. The components are sorted out. In the actual use process, there is a problem of incomplete sorting, and thus the full recycling of garbage cannot be realized.
