High-efficiency comprehensive winnowing equipment with functions of raising dust control and separation of objects with approximate specific gravity

Abstract

The invention discloses high-efficiency comprehensive winnowing equipment with functions of raising dust control and separation of objects with approximate specific gravity, and relates to the field of garbage treatment. The equipment comprises a first-stage fan assembly, a second-stage fan assembly, a third-stage fan assembly, a first-stage rotating hub assembly, a second-stage rotating hub assembly, a bouncing belt section, a winnowing light object discharging belt conveyor, a winnowing bin, a settling chamber and an air return structure. According to the equipment, three-stage winnowing is conducted on light objects through the first-stage fan assembly, the second-stage fan assembly and the third-stage fan assembly, and two-stage winnowing is conducted on heavy objects; materials which are sorted out are scattered and thinned step by step through the first-stage rotating hub assembly and the second-stage rotating hub assembly, the impurity rate of winnowing heavy objects is reduced, the winnowing quality is improved, four-stage separation of the light objects is achieved through the bouncing belt section, and then efficient comprehensive winnowing is achieved. The air return structure uses wind power internal circulation for dust raising control, and the environmental protection requirement is met. An air return port filter screen is automatically cleaned through a cleaning device, the labor intensity of workers is reduced, and frequent shutdown is avoided.

Description

technical field [0001] The application relates to garbage disposal equipment, in particular to a high-efficiency comprehensive winnowing equipment with the functions of controlling dust and sorting objects with close specific gravity. Background technique [0002] Most of the general air separation equipment is first-level wind separation, which only conducts a wind-force specific gravity separation on the incoming materials to obtain two types of materials, light and heavy, so the purity of the first-level air separation products cannot be guaranteed. Based on this, in order to ensure the purity of the air-selected products, some equipment manufacturers often add another air-selected equipment when the quality of the air-selected products of the current air-selected machine cannot meet the requirements. Carry out further selection respectively, but the quality of the winnowing material after winnowing in this scheme is still not ideal, and has increased equipment investment...

Problems solved by technology

[0002] The general large-scale winnowing equipment is mostly first-level winnowing, and only one wind-force specific gravity sorting is performed on the incoming materials to obtain two types of materials, light and heavy, so the purity of the first-grade winnowing products cannot be guaranteed.

Based on this, in order to ensure the purity of the air-selected products, some equipment manufacturers oft
