Refined classification system and treatment method of domestic waste

Abstract

The invention discloses a refined classification system for domestic garbage and processing methods, Refined domestic waste classification system, including a conveyor, a garbage crusher and a magnetic separator are installed above the conveyor, the outlet of the garbage crusher is directly facing the upper surface of the conveyor, and a plastic recycling machine is installed below the outlet of the conveyor , There is a drum screen under the discharge port of the plastic recycling machine, and a composting raw material bin and an incineration raw material bin are arranged under the drum screen. It can realize 4 types of material separation. The first type is the separation of metal objects, the separation of plastic materials, the separation of composting raw materials and the separation of incineration raw materials. The separation effect is good and the cost is low. It solves the single method of separation according to weight. To achieve the purpose of separating by material type.

Description

technical field [0001] The invention relates to a sorting treatment device and a treatment method for garbage, and belongs to the technical field of environmental protection sludge treatment. Background technique [0002] In the field of garbage sorting, there are many garbage sorting devices in the prior art. For example, the patent name is: a horizontal wind-powered garbage fine sorter. The guide plate, compared with the existing technology, adds a guide plate. When the material enters from the material inlet, it slides into the air separation chamber along the guide plate. Since the guide plate is designed to be inclined, it is difficult to combine gravity and guidance. Next, after the external wind drive is removed, the heavy materials are thrown out at a shorter distance, and the light materials are thrown out at a longer distance. At the same time, the inclined guide plate has a blocking effect, which can cause the materials to fall For dispersion, the material is alr...

Problems solved by technology

[0003] The above-mentioned patent uses wind force sorting to classify substances of different weights, but this method cannot achieve fine separation processing. For example, the metal part is heavy, and other glass structures are also heavy. Separating according to the structural design of the above-mentioned patent will cause Sorting metal structures and glass together, and for example, paper and plastic bags are lightweight structures, so they will be sorted into the same area, so the above-mentioned wind separation device can only roughly separate heavier garbage and lighter garbage Garbage separation, but this kind of separation method is far from meeting the requirements of fine classification processing, and fine classification processing needs to classify the same type of materials, for example, metal objects need to be classified into one class, plastic bag structures into one class Combustible materials are classified into one class, and non-combustible materials are classified into one class

Such a requirement cannot be achieved with the current technology.
