Benefits of technology

This patented technology improves household cleanliness during disposal processes such as rubbish collection. It separates different types of wastes before entering it's bin or container. Its technical effect includes improved sorting efficiency, effective use of resources like water, energy usage, and environmental friendings compared to current methods that require multiple stages of processing.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the management of house refuse (Waste) that has been discarded over several years due to its harmful effects on human well being and environmental concerns. Current solutions involve burning them away at home instead of finding new ones from scattered collection sites. However, these techniques have limitations because their effectiveness depends heavily upon factors like material type, moisture content, and particle size distribution. There remains an urgent unmet demand for improved ways to efficiently dispose of Wastes containing various types of materials including stone, metal scraps, plastic containers, rubbish residue, and nonorganics.

Embodiment Construction

[0016] refer to figure 1 An example of application of the device and method is illustrated.

[0017] Firstly, the domestic waste is magnetically separated by the magnetic separator on the feed belt, and then enters the crusher for crushing, and then is transported into the winnowing room through the feeding belt in the winnowing unit, and the average cross-sectional wind speed in the winnowing room is controlled by a circulating fan to 8m / s , air volume 34000m 3 / h, domestic waste is sorted due to the difference in density in the winnowing room. The heavy matter in domestic waste will directly fall into the heavy matter storage bin due to its high density; the medium-heavy matter in domestic waste hits the diversion drum 1 driven by the wind force, and falls into the medium-heavy matter storage bin under the action of its diversion , the rotating speed of drum 1 is 19 rpm; the light matter in domestic waste will continue to move forward under the drive of the wind, and will

Abstract

The invention relates to an air separation device and a method for domestic garbage. The device comprises a preprocessing unit and an air separation unit, wherein the preprocessing unit contains a feed belt, a magnetic separator and a crusher, and the air separation unit comprises a charging belt, a dedusting filter cartridge, a circulating fan 1, an air separation chamber, an air return pipeline, a roller 1, a roller 2, a circulating fan 2, a heavy substance storage bin, an intermediate-weight substance storage bin, a light substance storage bin and the like. In the invention, the separation of the domestic garbage is realized by the following method: the domestic garbage enters the magnetic separator and the crusher by the feed belt for preprocessing, then enters the air separation unit and enters the air separation chamber by the charging belt, the air speed and the air quantity in the air separation chamber are controlled, heavy substances, intermediate-weight substances and light substances in the domestic garbage respectively fall into the respective storage bins, and the return air is connected to the dedusting filter cartridge by a pipeline and is returned to the circulating fans after the return air is dedusted.
