Description

Technical Field

[0001] The invention relates to the technical field of waste incineration fly ash-based foam ceramics, in particular to a waste incineration fly ash-based foam ceramic and a preparation method thereof. Background Art

[0002] Garbage fly ash-based foam ceramics are a type of ceramic material made from fly ash produced by waste incineration as the main raw material. This type of ceramic has the characteristics of light weight, Class A fireproof and non-combustible, low water absorption, easy cutting, corrosion resistance, and no cracking. It can be used as ceramic insulation boards, ceramic wall panels, ceramic insulation and decorative integrated boards, etc. Its preparation and processing flow mainly includes two steps: preparing powder blanks and sintering. First, the raw materials such as waste incineration fly ash, quartz sand and additives are mixed with water, ball milled in a ball mill to obtain a uniformly mixed slurry, and then dried to obtain a powder blank. Next, the powder blank is filled into a mold and placed in a high-temperature furnace for sintering to finally obtain garbage fly ash-based foam ceramics.

[0003] Based on the physical and chemical properties of fly ash-based foam ceramics, we can conclude that ceramic masonry made from this material can be used in a variety of building facilities and play specific functions. The following are some possible application scenarios and functions:

[0004] Thermal insulation building facilities: Fly ash-based foam ceramics have good thermal insulation properties. Therefore, masonry made from them is particularly suitable for building facilities that require good thermal insulation effects, such as walls, roofs, insulation layers, etc. In winter, it can reduce heat loss and improve indoor thermal insulation effects; in summer, it can block the intrusion of external heat and reduce indoor temperature, thereby saving energy and improving the energy efficiency of buildings.

[0005] Fireproof building facilities: Since garbage fly ash-based foam ceramics have the characteristics of fireproof and non-combustible, the masonry prepared from it is suitable for building facilities that require high fire protection, such as fire walls, fire partitions, high-temperature factories, etc. When a fire occurs, it can effectively prevent the spread of the fire and protect the safety of people and property.

[0006] Lightweight structure building facilities: This material is lighter than traditional masonry, which can reduce the self-weight of the building and reduce the burden on the foundation. Therefore, it is suitable for lightweight structure building facilities such as low-rise buildings, temporary buildings, mobile homes, etc. The use of this lightweight masonry can not only reduce construction costs, but also speed up the construction progress.

[0007] Environmentally friendly building facilities: The preparation of fly ash-based foam ceramics utilizes the fly ash produced by garbage incineration, realizes the resource utilization of waste, and reduces environmental pollution. Therefore, the masonry prepared by it conforms to the concept of environmental protection and is suitable for environmentally friendly building facilities such as green buildings and ecological buildings.

[0008] The overall quality of existing ordinary bricks and stones is generally heavier than that of garbage fly ash-based foam ceramic bricks and stones. Under the premise of constructing temporary buildings after disasters for the victims to live in, the overall quality of ordinary bricks and stones is heavier and the construction operation is more burdensome than that of garbage fly ash-based foam ceramic bricks and stones. In view of this, we propose a garbage incineration fly ash-based foam ceramic and a preparation method thereof. Summary of the invention

[0052] Compared with the prior art, the present invention has the following beneficial effects:

[0053] 1.

The light fly ash-based foam ceramic body effectively reduces the construction and operation burden of personnel during the construction of temporary buildings after disasters, thereby improving the operation and speeding up the construction efficiency, and facilitating the rapid formation of temporary buildings after disasters.

The above operation is used to facilitate construction work for personnel without construction experience, and the staggered filling of the solidified cement improves the stability of building formation.

[0054] 2. The present invention forms an integral structure by relatively fitting the molding sleeve A and the molding sleeve assembly B, and relatively separating and unfolding them so that the molding assembly A and the molding assembly B can respectively process and shape the feed hole and the cylindrical hole. The above two operating structures effectively improve the functionality and meet the requirements for the production of fly ash-based foam ceramic bodies.

[0055] 3. The present invention connects the driving shaft with the driving keyboard key through the keying protrusion and the keyway, so that the servo driving motor drives the driving keyboard and the driving shaft to rotate by driving the synchronous wheel to rotate the driving belt, and at the same time drives the driving shaft to perform lifting and lowering adjustment through the linear stroke return of the push rod to drive the auxiliary rotating seat.

[0056] 4. The present invention adopts a rotating cavity with a notch and a fan-shaped cross-section, and at the same time, the arc angle of the rotating cavity cross-section is set to be greater than 180 degrees, so that the molding sleeve assembly B and the molding sleeve A can be freely opened and separated in the integral structure and the expanded structure state, which is a necessary connection measure to achieve the two structural shapes; and by rotating the screw to cause the adjustment block to descend and adjust, the inclined force surface B is used to extrude the inclined force surface A, so that the friction extrusion block slides outward for adjustment, so that the outer surface of the friction extrusion block is in friction contact with the sliding seat. Through this setting, the hovering height of the molding sleeve assembly B is effectively controlled to control the accuracy of the channel forming.

The present invention arranges the mesh belt so that in the expanded structural state, the mesh belt is expanded and tightened to squeeze the wet material in the mold to form the feed hole; at the same time, in the overall structural state, the rotating spring is rotated and twisted in the expanded structure, and the synchronous drive winding shaft is rotated during the adjustment process from the expanded structure to the overall structure. The mesh belt is wound by rotating the winding mesh belt to prevent the mesh belt from being exposed to the outside and affecting the cylindrical hole forming operation.
