Multi-level dissolving-out tank structure for extracting coal ash

Abstract

The invention discloses a multi-level dissolving-out tank structure for extracting coal ash. The multi-level dissolving-out tank structure comprises a dissolving tank, wherein a cavity is formed in the dissolving tank, a cover plate is movably clamped to the upper side of the cavity, a rotating cavity is formed in the cover plate, a first gear is rotationally connected to the inside of the rotating cavity, an oil cylinder is fixedly connected to the upper side of the first gear, and a telescopic rod is connected to the inside of the oil cylinder in a sliding manner; and inlet / outlet is formedin the side wall of the dissolving tank, a rotating block is rotationally connected to the side wall of the inlet / outlet through a rotating shaft, a sliding chute is formed in the rotating block, a sliding strip is connected to the inside of the sliding chute in a sliding manner, and sliding plate is fixedly connected to the side wall of the sliding strip. According to the multi-level dissolving-out tank structure, the insides of trays in the cavity are placed in a layering manner by virtue of a support block and a support plate, coal ash for extracting aluminum oxide is put into each tray layer by layer and is not integrally stacked together, so that the coal ash in the trays can be in adequate contact with water in the cavities.

Description

technical field [0001] The invention relates to the technical field of dissolution equipment, in particular to a multi-level dissolution tank structure for extracting alumina from fly ash. Background technique [0002] With the steady development of my country's energy industry and the rapid development of the power industry, the discharge of fly ash has increased sharply. Many oxidized components of fly ash can be used as resources, from which we can extract alumina materials. However, in the process of extracting alumina, the water-soluble substances are extracted first, otherwise it will affect the refining of alumina. Most of the common devices for extracting the aqueous solution substances in fly ash are a simple container, and then the treated The fly ash and water are directly poured into the container for water fusion. Since the fly ash is directly poured into the container, the fly ash and water are in a static state in the container, and the fly ash at the bottom of ...

[0002] With the steady development of my country's energy industry and the rapid development of the power industry, the discharge of fly ash has increased sharply. Many oxidized components of fly ash can be used as resources, from which we can extract alumina materials. However, in the process of extracting alumina, the water-soluble substances are extracted first, otherwise it will affect the refining of alumina. Most of the common devices for extracting the aqueous solution substances in fly ash are a simple container, and then the treated The fly ash and water are directly poured into the container for water fusion. Since the fly ash is directly poured into the container, the fly ash and water are in a static state in the container, and the fly ash at the bottom of the container is not easy to be fully mixed with water. contact, the water-soluble substances inside the fly ash cannot be completely dissolved in water, and it is troublesome to take the fly ash out of the container, so we propose a method for extracting alumina from fly ash The multi-level dissolution tank structure
