Description

Tne traveling manufacturing equipment of the foaming concrete

The present invention relates to a foamed concrete manufacturing apparatus, and more particularly to a foamed concrete manufacturing apparatus in a trailer for manufacturing a portable cement storage tank, industrial by-products and fine aggregate storage tank, foam storage tank, water tank, foaming machine, mixing tank and foamed concrete It is possible to easily manufacture and apply foamed concrete at the site by connecting and configuring the feeder, and to have uniform and constant characteristics through accurate metering of the materials used. The present invention relates to a mobile foam concrete manufacturing apparatus that can achieve the effect of minimizing the problem.

In general, lightweight concrete by foaming action is classified into three types of high pressure steam wild animal (ALC), atmospheric steam curing (PALC), and cast-in-place lightweight concrete. Among the curing methods, foaming method and preform ( Pre-foam) and Mixer foam (Mixfoam) method.

These types can be distinguished by mixing the foaming agent in the slurry and foaming and mixing the foam in the slurry in advance. A method of foaming bubbles in a slurry is a method used in manufacturing a product such as ALC, and uses a metal powder foaming agent (AL powder, Zn powder, etc.).

On the other hand, the method of making the bubble in advance and mixing it into the slurry is a method used in the production of in-situ cast concrete, using an organic foaming agent (vegetable foaming agent, animal protein foaming agent, etc.). Since the final volume can not be determined by mixing foaming agent in the slurry and foaming, as in the manufacture of ALC, it is cut and cured to a certain size after complete foaming, but the method of preparing the foam in advance and mixing it with the slurry is poured only as the design volume Since curing is necessary, there is a difference in that processing after pouring is unnecessary.

In addition, the metal powder foaming agent reacts in a high temperature condition in most cases, the chemical reaction does not occur at room temperature or tends to occur late, the production amount at the time of manufacturing at room temperature is small, the productivity is low, while the organic foaming agent is at room temperature It is easily foamed at, so it is mainly used for on-site pouring.

The prior art using a dry powder foaming agent is a technique for manufacturing ALC products using metal aluminum powder or metal zinc powder, and in order to manufacture powder-foamed concrete for on-site casting, weak organic foaming agents (animal protein foaming agents, plant standing foaming agents) And the like) have been used.

Conventionally, a method of manufacturing lightweight concrete by bubble action in the field is to dilute organic foam stock solution at a concentration of about 2% in a large container of about 20-30 tons, and then pressurize it to the foamer using a foam liquid transfer pump. At this time, the compressed air generated by the high-pressure compressor is injected into the bubble liquid transferred to the foaming machine to make a group of bubbles to mix with the mortar slurry.

Here, the specific gravity of the bubble group is generally about 0.035 ~ 0.05 and mixed with the cement slurry to produce a limited bubble concrete, but since the shape or size of the foaming machine making the bubble is not constant for each equipment, Quality can only be manufactured differently.

In addition, since the concentration of diluting the bubble undiluted solution varies from about 2% to 7% depending on the worker, the specific gravity of the bubble group is varied, as well as the quality of the lightweight foam concrete becomes uniform. In addition, since the bubble stock solution being used is an organic substance, it is difficult to process the foam dilution after the completion of the foam concrete pouring process, and there is a problem such that when the remaining foam solution is left or is discharged to the sewer, odor is generated.

As the generation of bubble group is important in light weight concrete by bubble action, more advanced techniques are used to prevent the cost increase and to leave the bubble liquid by using the Gipon solution and mixed water separately without diluting Gipon solution. There may be a way to prevent this, but this is a problem that a complicated device is required, and still poses a problem of unstable quality.

As described above, the conventional foam concrete manufacturing apparatus is difficult to switch to various foaming ratios, and it is not only able to freely control the mixing ratio of foamed concrete required for the production of foamed concrete using industrial by-products or fine aggregates, but also uniform density.
