Description

Manufacturing apparatus and manufacturing method of waste structure TECHNICAL FIELD

The present invention relates to an apparatus and method for manufacturing a waste structure.

As industrial waste increases with the progress of industrialization, interest in recycling of industrial waste is increasing. Uncontaminated waste glass that can be recycled is melted and recycled, but most are recycled as inexpensive industrial glass or tile materials.

In the case of contaminated or mixed waste glass, since it is difficult to use it as an original usable material, it is landfilled after paying the landfill fee. In addition, in the case of cement kiln dust generated during clinker production in the cement industry, since the concentration of chlorine causing cracks and corrosion is high, most of the cement kiln dust is landfilled.

Accordingly, there is a need for a technology that can effectively recycle waste (waste glass, cement kiln dust, etc.) in terms of resource and energy saving and environmental conservation.

1 to 2 , the apparatus 10 for manufacturing a waste structure according to an embodiment of the present invention may include a crusher 100 , a mixer 200 and a molding machine 300 .

Specifically, the crusher 100 may crush raw materials including waste glass, waste and other impurities. The waste may include at least one of cement kiln dust, cordierite, petro coke ash, semiconductor sludge, or sand. Of course, these cement kiln dust, cordierite, petro coke ash, semiconductor sludge or sand are only one type of waste applicable to the present invention, and in addition to these wastes, various types of waste may be applied to the present invention.

The crusher 100 may crush the raw material to a predetermined size or less. For example, the crusher 100 may crush the raw material to a size of 200 mesh or less through a physical crushing process. To this end, the crusher 100 may include a crushing blade (not shown) for crushing the raw material, and a rotating motor (not shown) for rotating the crushing blade. Since the crusher 100 is a conventional crusher capable of crushing the raw material to a size of 200 mesh or less, a detailed description thereof will be omitted.

The mixer 200 may receive the raw material crushed to a predetermined size or less from the crusher 100, and may uniformly mix the supplied raw material by stirring. As the mixer 200, a conventional mixer may be used for uniform mixing of raw materials.

The molding machine 300 may mold the raw material uniformly mixed by the mixer 200 into a waste structure. The waste structure may be molded into a foamed structure having a low density by the molding machine 300 , or may be molded into a high strength structure having high strength by the molding machine 300 .

When the temperature of the raw material reaches the molding temperature, the molding machine 300 may mold the raw material into a waste structure by maintaining the temperature of the raw material at the molding temperature for a preset molding time within a preset humidity range.

For example, the molding machine 300 may heat the raw material to 80° C. (first molding temperature) at 2° C./min (first temperature rise temperature). When the temperature of the raw material reaches 80 ℃ (first molding temperature), the molding machine 300 within the 80 ~ 98% humidity range, the temperature of the raw material for 24 hours (first molding time) 80 ℃ (first molding temperature) ), the raw material can be molded into a high-strength structure.

And if the water is more than 10 wt%, the bonding between the waste powder may not be properly made and may not be well agglomerated.

The molding machine 300 may heat the raw material to 900° C. (second molding temperature) at 5° C./min (second temperature rising temperature). When the temperature of the raw material reaches 900 ℃ (second molding temperature), the molding machine 300 within the 80 ~ 98% humidity range, the temperature of the raw material for 3 hours (second molding time) 900 ℃ (second molding temperature) ), and the raw material can be molded into a foam structure. In this way, after heating the raw material to 900 ° C. (second molding temperature) at 5 ° C./min (second temperature rising temperature), the temperature of the raw material is heated within the range of 80 to 98 % humidity for 3 hours (second molding time). If maintained at 900 ° C. (second molding temperature) during this time, the porosity of the structure can be improved by reducing the destruction of the crystal structure of the raw material.
