ある。Description: TECHNICAL FIELD The present invention relates to an apparatus for supplying a foaming liquid to a concrete mixer in the production of cellular concrete.
（従来の技術） 気泡コンクリートの製造には、従来、化学反応によっ
てガスを発生させる方法や、起泡剤をスラリー中に添加
して混合過程で起泡させる方法、或は、発泡機で別につ
くった泡をスラリーと混合する方法が行なわれている。(Prior Art) Conventionally, cellular concrete is produced by a method of generating a gas by a chemical reaction, a method of adding a foaming agent to a slurry to foam in a mixing process, or a method of separately producing the foam using a foaming machine. A method of mixing the foam with a slurry has been practiced.

型、養生を経て気泡コンクリート製品とするのである。A gas-liquid mixing method using this foaming machine is disclosed in JP-A-63-1565.
As described in Japanese Patent Publication No. 26, a pressurized gas and liquid are simultaneously injected from one side into a cylindrical body containing microsphere nodules and ejected from the other side. . Then, the foamed liquid of the gas-liquid mixture which has been jetted out is sent to a concrete mixer and mixed with ready-mixed concrete. After molding and curing, the foamed concrete product is obtained.

きた。(Problems to be Solved by the Invention) However, concrete products manufactured by using a method of mixing foaming liquid from a foaming machine with ready-mixed concrete exhibit variations in specific gravity values, lack quality stability, and have a high yield. It turned out that there was no problem, and a solution was requested.

は、これまでの多くの実験により観察されている。In view of the introduction of the foaming liquid into the concrete mixer from the above conventional foaming machine, foamed concrete was supplied at the beginning of the mixer operation because foamed concrete was manufactured by a batch system by kneading the mixer. Thereafter, the operation of the foaming machine is stopped and intermittent operation is performed from kneading to discharging, and then to charging of ready-mixed concrete. And it seems that the main cause of the problem is that the foaming liquid is intermittently ejected from such a foaming machine.
That is, if the foaming machine is operated intermittently, the temperature change in the foaming machine increases, which causes a change in the volume and gap of the microspheres in the cylinder, and also causes the microspheres to change during the downtime. The liquid will stick and make the street worse, and therefore, in practice, the mixing of gas and liquid will be less uniform and the size of the foam will also be uneven. This has been observed in many previous experiments.

移動させる。In the apparatus of the present invention, the foaming liquid supplied to the concrete mixer 2 is jetted from the lower end of the foaming machine 1 as described above. Compressed air into the body 4 of the foamer 1 than the tube R 1, also stock enters pipe 11 feed from tube R 2, it is bubbler into the body 4 in a state of gas-liquid mixture. Then, the compressed air and the stock solution that have been injected repeat compression, diffusion, refraction, branching and merging while passing between the respective spheres to form a foaming liquid which is a liquid in which gas is evenly mixed. And is supplied downward into the concrete mixer 2. In this case, the compressed air is sent from the air source 17 through the opened solenoid valve SoL-1, and the undiluted solution is sucked and discharged from the undiluted solution tank 13 by the hydraulic pump 21 and sent through the solenoid valve SoL-2. in the initial operation, until the feed volume than the hydraulic pump 21 reaches a predetermined value (short-time), the electromagnetic valve SoL-3 of the return pipe R 4 together with the temporarily closes the solenoid valve SoL-2 the open, circulate a stock solution in the return pipe R 4 from a stock solution supply pipe R 2, when the amount of feeding has reached a predetermined value, the electromagnetic valve SoL-3
Is closed, and the solenoid valve SoL-2 is opened to feed the liquid to the foaming machine 1. In this case, the swing motor 12 is operated by the switching operation of the solenoid valve SoL-4, and the foaming liquid receiver 3 is moved from the position immediately below the foaming machine 1 as shown in FIG. Move to

In this case, stock from the stock solution feed pipe R 2 solenoid valve SoL-2 remains open is to be fed to the foaming machine 1, compressed air solenoid valve So
Close L-1 and interrupt feeding to foaming machine 1. Therefore, only the undiluted solution is sent to the foaming machine 1, and the undiluted solution coming out of the foaming machine 1 enters the foaming liquid receiver 3 and passes from the return pipe R 3 to the undiluted solution tank 13.
And the stock solution is circulated.
In this way, the foaming machine 1 does not stop the operation even when the foaming liquid is not supplied to the concrete mixer 2, and only the undiluted solution is constantly flowing in the foaming machine 1.

At that time, while the feed of the undiluted solution to the foaming machine 1 is continued, the solenoid valve SoL-1 is opened to send compressed air to the foaming machine 1 again.
The foaming liquid is sent to the concrete mixer.

It is better to stop the blowing of the foaming liquid for a short period of time. During that time, the solenoid valve SoL-2 is closed temporarily, the solenoid valve SoL-3 is opened, and the liquid from the hydraulic pump 21 is connected to the pipe R 4. From the original solution tank 13. In this case, the suspension of the liquid supply to the foaming machine 1 is extremely short, so that there is no possibility that the influence of the suspension of the liquid supply in the foaming machine 1 is caused.

ある。(Effects of the Invention) As described above, the apparatus of the present invention includes a foaming machine that feeds a stock solution and compressed air into a cylindrical main body containing a spherical nodule and ejects a foaming liquid, and a foaming machine. When the foaming liquid is not fed into the concrete mixer between the concrete mixer for kneading the liquid and the ready-mixed concrete, the foaming liquid is received in order to continuously circulate the foaming liquid in the foaming machine. The foaming liquid receiver to be returned to the undiluted liquid tank is movably provided in a position directly below the foaming machine for receiving the foaming liquid and a position not to interrupt the feeding of the foaming liquid to the concrete mixer, or is provided adjacent to the foaming liquid receiver. Since the foaming machine is movably provided above the concrete mixer and the foaming liquid receiver, the foaming machine is installed as before even when the foaming liquid is not supplied to the concrete mixer. Stop driving In addition, it is possible to always keep the foaming machine in the operating state and to distribute the stock solution therein. Therefore, the temperature change in the foaming machine can be suppressed to a very small level, and there is no danger that the undiluted solution will adhere to or harden the microspheres housed in the main body, and the uniform spacing between the microspheres can be maintained. The liquids can be mixed uniformly, and as a result, a number of excellent effects can be obtained, such as the production of foamed concrete of stable quality without variation in specific gravity.
