Air flow different specific sorting device for household garbage

Abstract

The invention discloses an air flow different specific sorting device for household garbage. The device comprises a bulk material room, a tuyere, a fan, a blanking room, a blanking adjustor and a circulating air pipeline. A closed high pressure air flow formed by the tuyere, the fan and the circulating air pipeline is negative pressure in the blanking cavity, the other regions of the bulk material room are air flow fields of positive pressures, and a mixed garbage material is driven to deviate from a gravity track according to specific gravity difference. The smaller the specific gravity is, the greater the deviation is. Light materials fall into the blanking room opposite to the indoor tuyere of the bulk material room, so that a different specific sorting effect is achieved.

Description

technical field [0001] The invention relates to the fields of environmental protection, mechanical automation and the like, and in particular relates to a sorting device for garbage air flow with different specific gravity. Background technique [0002] With the continuous deepening of my country's urbanization process and the improvement of people's living standards, the amount of waste per capita continues to rise, people's awareness of environmental protection is increasing, the contradiction between increasingly strict environmental laws and regulations and the backward level of waste disposal is becoming more and more prominent, big cities are facing The dilemma of "garbage siege", the effective disposal of domestic waste needs to be solved urgently. With the diversification of production and the increasing number of product types, the size and shape of domestic waste also show a trend of becoming more and more complex; the characteristics of complex components of urban ...

AI Technical Summary

Problems solved by technology

[0003] The air flow and air pressure of the traditional air flow sorting technology are small, which affects the sorting effect, brings about the problem of incomplete sorting, and also affects the sorting efficiency

[0004] In the traditional air flow sorting device, the fan, air inlet and ventilation duct are not connected into a closed air circulation pipeline. The air inlet of the fan and the outlet of the ventilation duct directly lead to atmospheric pressure, so negative pressure cannot be generated near the blanking chamber. Affect sorting efficiency

[0005] The composition of garbage is variable. Traditional sorting equipment has fixed air flow and blanking parameters, and cannot adjust parameters according to composition changes, which affects the sorting effect.
