Description

technical field [0001] The invention relates to concrete products, in particular to the improvement of a foam concrete pouring device and its working method. Background technique [0002] At present, the foam concrete produced in China is mainly a kind of porous concrete formed by adding foam with cement as the colloidal material and fly ash as the aggregate. Its working process is: the dry powder screw conveyor transports the dry powder in the dry powder silo into the weighing hopper above the thermal insulation slurry mixer, and the measured dry powder is unloaded into the mixing drum of the foam concrete mixer, and at the same time, it is sent to the mixing drum Add a certain amount of water, after a long time of stirring evenly, the mixer will discharge the mixed foaming slurry into the receiving hopper of the grouting pump, and the grouting pump will send the foaming slurry into the body to be cast through the grouting head inside the cavity. [0003] The existing pro...

AI Technical Summary

Problems solved by technology

[0003] The existing problems are: 1. The foam concrete produced by the physical foaming method has a relatively heavy bulk density, so its thermal insulation performance is also poor; The workpiece has a long conveying stroke and poor fluidity; 3. After the foaming slurry is injected into the cavity, it will shrink during the curing process, and there will be a gap with the cavity wall, the combination is not firm, and the upper part of the workpiece is often sunken; affecting the thermal insulation performance; 4 , single-head pouring, low efficiency of the workpiece

This case guarantees the quality of the product, but in the work, single-head pouring is used, which leads to long production time and low efficiency; the quantitative mixer is weak in adjustability and cannot adapt to different cavity volumes; the pumping system is adopted increased production costs

[0005] The case has the following problems: the chemical reaction has already occurred in 3 / 4 of the mixing foam collection box, and then enters the foam concrete pump 6 through the pipeline, the three-way butterfly valve 5, and the main discharge pipe 501, and then sends out

After the chemical reaction of the foamed concrete, the tailings are easy to expand and condense in the pipeline, valve body, and pump body, resulting in the failure of the aforementioned components

We can think that the problem of "quantitative" and "proportion uniformity" is better solved in this case, but there are great hidden dangers, which are likely to cause 501 and failure of foam concrete pump 6)
