Problems solved by technology

Due to the relatively simple structure, there is no auxiliary sufficient humidification device and cleaning device in the conveying section, so the powder cannot be fully humidified, and the muddy powder will be blocked in the conveying section, or excessive water will cause slopping and other phenomena.
The above dust-free loading machines for powder materials are all based on the above-mentioned humidification treatment, and it is difficult to effectively control the dust generated during dust transportation
In addition, the wet and dry dual-purpose powder loading machine invented by me adopts the technical scheme of "zero material level" small drop, negative pressure vacuum cover and external spraying. It is still difficult to effectively control the dust during the loading operation when the gas ash of the blast furnace gravity dust collector is unloaded and loaded

Embodiment Construction

[0024] In the method of the present invention, the output powder is transported through the conveying device, and after the first-stage humidification is performed on the powder in the conveying device, the powder that has not been fully humidified is transported to an enlarged diffuser to generate dust, and then in the enlarged The raised dust is humidified in the second stage in the release container, and then discharged. After the powder is humidified in two stages, the dust is sprayed and dusted before being discharged. Spray and press the discharged dust again.

[0025] Before spraying and humidifying, the spraying and humidifying device shall be heated, deiced and thawed or blocked.

[0026] In the conveying device, the powder is humidified at the first stage while pushing the powder for scraping and stirring.

[0027] The multi-stage humidification method of the present invention has multiple types such as two-stage, three-stage, and four-stage. Among them, the humid...

Abstract

The invention is concerned with the multilevel spray powder wetting method and the equipment and the powder non-dust car loader. It is: transports the outputting powder by the transporting equipment, processes the first order wetting to the powder in the transporting equipment, transports the un-wetting powder to a container to create dust, processes the second order wetting to the rising powder in the container, vents it. The invention can achieve the enough wetting of the powder, and control the dust, in order that the wetting powder is saturation status, which breaks through the traditional wetting governing localization.

Description

technical field [0001] The invention belongs to a powder material humidification method and device and a dust-free loading machine for powder materials, in particular to a multi-stage spray powder material humidification method and device and a powder material dust-free loader based on multi-stage spray powder material humidification. Background technique [0002] Blast furnace gravity dust collector unloads dust and dust collected by ordinary dust collectors and other powdery materials. The current ash unloading and loading process includes two-shaft stirring type and drum type humidification and ash unloading device, which are all mixed with water in the horizontal section. Because After the powder is mixed with water, the conveying resistance is large, and the muddy powder is easy to stick to the stirring device and the casing, causing the humidification equipment to be easily blocked, the failure rate of the mechanical equipment is high, the maintenance is difficult, and ...
