[Problem that the idea aims to solve]

Normally, when mixing powder and liquid, the powder and liquid are placed separately in a tank. However, in the conventional configuration, powder and liquid are mixed together in a tank. The mixing speed is not high, and for a while after adding the specified amount of powder. The powder and liquid cannot mix completely, and the powder remains in a lump and floats in the liquid. The mixture in this state can be used in propulsion construction methods, for example, as a lubricant for propulsion pipes. When used, it prevents lumps of powder from sticking to the conveying pipe that conveys the lubricant to the propulsion device. There is a risk that the pipes will be clogged by growth, or, for example, When the combined mortar is used as a construction material, the raw powder mixture is There is a risk that it will harden in a rough shape, resulting in an uneven and poor-quality finish. There is. For this reason, the powder does not turn into powder immediately after being added to the liquid. It would be good if it could be mixed with However, in order to do this, workers must mix the powder and liquid. A predetermined amount of powder must be added into the fluid in small portions depending on the However, there was a problem in that it took a lot of effort and time. This invention was developed in consideration of the above circumstances, so powder can be easily added to liquid without complicated work. The purpose is to provide a device that can mix powder immediately after mixing without turning it into powder. shall be.

[Means to solve the problem]

To achieve the above purpose, a tank for containing a mixture of liquid and powder, and a front The characteristic structure of the present invention in a mixing device equipped with a stirrer for stirring the mixed substances in the storage tank is , a container capable of containing powder is disposed in the tank, and a plurality of holes penetrating inside and outside are provided in the tank. Formed in the wall of the container, the contents inside the container are pushed outward through the hole while stirring. It is equipped with an extrusion device and a drive device for driving this extrusion device, and In addition, for reasons to be described later, the container is placed in a position where it is immersed in the mixed substance in the tank. or the container is formed into a cylindrical shape and the extrusion device is centrifugal. a rotating blade that presses the contents in the container against the side wall portion of the wall of the container with force; and adding a point on the side wall portion with the plurality of holes formed therein. Both are valid.

[0005]

[Effect]

As the powder is directly introduced into the container, multiple holes penetrating the inside and outside are formed. is formed on the wall of the container, and the contents inside the container are allowed to flow outward through the hole while stirring. By having an extrusion device for extruding and a drive device for driving this extrusion device, , the powder is successively passed through holes formed in the wall of the container by the driving device and the extrusion device. However, when the powder is pushed out through the hole, the powder is pushed out through the hole. While being passed through a sieve, large chunks of powder are ground into smaller pieces. did Therefore, it is pushed out of the container in the form of small pieces that are easily mixed with the liquid. As soon as the powder enters the tank outside the container, it is dispersed in a liquid without powder. can be mixed separately. Moreover, as shown in claim 2, the container is placed inside the tank. If it is installed in a position where it will be immersed in a mixed substance, the powder and liquid should be uniformly distributed as described above. In addition to being able to form small pieces that are easy to mix, it also prevents the liquid from being pre-mixed in the container. The mixing speed can be further improved. Moreover, as shown in claim 3 , the container is formed into a cylindrical shape, and the extrusion device uses centrifugal force to push the inside of the container into a cylindrical shape. The container is composed of rotating blades that press the contents of the container against the side wall portion of the wall of the container. In the case where the plurality of holes are formed in the side wall, the side wall is formed by rotating blades. Some of the powder that is pressed against the hole but not pushed out from the hole rises up and down. At the side wall, gravity acts so that it slides downward along the side wall. , making it difficult to stick around the hole.

[0006]

[Effect of the idea]

Therefore, immediately after adding the powder, mix it quickly so that it does not turn into lumps. This makes it possible to simultaneously input a large amount of a given powder, and as a result, In addition, the labor input can be reduced. In addition, the container is immersed in the mixed substance in the tank. If the mixing speed is increased and the amount of powder is This allows you to input the material at your own pace, improving work efficiency. Further, the container may be formed into a cylindrical shape. At the same time, the extrusion device uses centrifugal force to push the contents inside the container through the walls of the container. The plurality of rotating blades are configured to press against the side wall portion of the If pores are formed, it will be difficult for the powder to stick to the container and grow, reducing mixing performance. You can prevent it from happening.
