Classification system for winnowing garbage

Abstract

The invention discloses a garbage air separation sorting system that includes feeder, material pit, garbage crusher, magnetic separator, discharge port transferring belt, air separation sorter, separated material transferring belt. The garbage crusher includes frame and cabinet. Feeding funnel is set on the upper end of the box, and the discharge hatch is set on the bottom side. Reduction drives are set on the two sides. Four knife shafts are set in box in parallel. Cutter wheel is set on the knife shaft. The air separation sorter has a blower fan on the head and another blower fan on the top of the box. The invention improves the accuracy rate of sorting and the effect.

Description

technical field [0001] The invention belongs to garbage processing equipment, and in particular relates to a garbage winnowing and sorting system which performs winnowing and sorting after rubbish is crushed and treated. Background technique [0002] As we all know, the composition of waste is very complex, including kitchen waste, other components such as plastic, glass, metal, and even construction waste. When these garbage enter the combustion grate, it is easy to cause damage to the grate, or produce polluting gas, which affects the quality of exhaust emissions. In order to make the garbage entering the combustion grate more suitable for combustion, it is necessary to use a garbage crusher before the garbage enters the grate. Crushing, and then screening and sorting the garbage, screening out the garbage that is not suitable for entering the combustion grate, and then transferring it to the garbage incinerator for incineration to generate electricity, which can not only ...

AI Technical Summary

Problems solved by technology

The existing waste air separation and classification system is generally composed of a magnetic separator, a wind separator, a vibrating screen (or drum screen), and a crusher. The wind separator only includes a fan, and the wind direction is parallel to the horizontal line, resulting in light Garbage such as plastic bags floats in the air of the sorter, and the garbage sorting effect is not good; the vibrating screen (or drum sieve) is installed in the system, mainly because the front part of the system is not equipped with a garbage crusher or the garbage crusher installed cannot dispose of large pieces. Garbage crushing needs to filter the garbage, but due to the larger garbage and harder garbage, the screen is easily blocked and damaged; the existing garbage crusher consists of a feed hopper, a discharge port and a crushing system. The crushing system consists of a crushing box and parallel and counter-rotating crushing cutter shafts installed in the crushing chamber. The two cutter shafts are equipped with cutter wheels at intervals, and the cutter teeth are evenly distributed on the circumferential surface of the cutter wheels. The cutter teeth cooperate with each other to form scissors. If the distance between adjacent cutter shafts is too large, small garbage cannot be effectively shredded, and if the distance between adjacent cutter shafts is too small, larger garbage cannot be effectively shredded, and it is easy to jam the knife, causing the machine Can not work normally
