2 is a view showing a tank structure for storing mixed liquor according to an embodiment of the present invention.

2, the tank structure 1000 for storing mixed liquor according to an embodiment of the present invention includes a tank unit 100, a circulation unit 200, and a partition wall unit 300, and the screen unit 400 ).

The tank portion 100 can be partitioned into a side wall, a front wall, a rear wall, a ceiling, and a floor, as shown in FIG. 2, as a container capable of storing the mixed liquid 20 therein. In this case, the mixed liquid 20 means a semi-liquid mixture obtained by mixing at least one kind of solid component into a liquid.

Generally, the mixed liquid 20 to be used by mixing one or more kinds of solid components into a liquid has a problem in that the solid component in the liquid is separated from the liquid due to component characteristics, there is a problem.

Therefore, it is necessary to appropriately stir the mixed liquid 20 so that such solid component can not be separated from the liquid.

In this embodiment, the case where the tank structure 1000 for storing mixed liquor is a mud tank is described as an example. In this case, the mixed liquid 20 may be a liquid mud.

Since the liquid mud stored in the tank unit 100 has a high viscosity, if the mud circulation in the tank unit 100 is not smooth, the liquid mud can not be used and can be discarded. In order to prevent this, an impeller stirring the liquid mud may be installed inside the tank 100. However, in a region where the mud circulation can not be smoothly performed by the stirring by the impeller, the mud is fixed . In particular, there is a high possibility that the mud is fixed to the edge or apex region of the tank portion 100.

In order to solve this problem, conventionally, a method of spraying high-pressure fluid to a portion where the mud is fixed by installing a mud gun inside the tank 100 has been used. However, It is not easy to control, and there is a problem that the mud gun operates in the liquid mud while influencing the mud circulation by the impeller or the impeller.

In the case of fluids, especially in the case of mixed liquor 20, turbulence can occur in which fluid molecules move in an irregular and curvilinear manner during the circulation process. In such a turbulent flow, the mixed liquid 20 may not smoothly be discharged from the tank 100, and consequently, circulation and stirring of the mixed liquid 20 may not be performed smoothly.

Accordingly, the porous plate-shaped partition wall portion 300 is provided in a part of the tank portion 100, which is relatively likely to be densely packed with the liquid molecules of the mixture liquid 20 during the discharge of the mixed liquid 20, To pass through the holes of the partition 300.
