Abstract

PURPOSE:To provide a device to increase gas volume intruded in to liquid, stir and mix gas into the deep layer of liquid and so on by providing an intake vent on one side of a hollow drive shaft, and a flat blade in the axial direction at the other end, and providing an air conducting cap in parallel with the flat vane to form a slit-shaped exhaust vent. CONSTITUTION:A stirring vane 3 and an air conducting cap 4 are rotated by the rotation of a hollow drive shaft 1 to generate centrifugal force, and blast pressure generated by a forced flower 6 is also jointed to drain the liquid in the drive shaft quickly. At the same time, gas is supplied from an air intake 2 through a gas supply line of a hollow section, exhausted out of a slit-shaped air vent 5 and stirred and mixed in the liquid. By said process, a large volume of gas can be stirred and mixed into a deep layer of liquid in the form of microfoams, and intruded volume of gas can be controlled by controlling the number of rotation for a wide range of use requiring aeration such as intruding the gas into a fishpond or the like.

Detailed Description of the Invention <Industrial Application Field> The present invention is applicable to gas contamination during sewage treatment, gas contamination to fish ponds in fish farms, and cooling water. This invention relates to a self-priming gas mixing device used in fields that require gas mixing and other aeration.

〈従来の技術〉 液体（特に水）中に気体（特に空気、酸素）を混入する

の人心によって大きく左右されている。They were gas self-priming stirring type, compression pump type, etc. In either method, the purpose is aeration, and its effectiveness is greatly influenced by the amount of mixed gas, the position at which it is stirred and mixed in the liquid, and the concentration of bubbles of mixed gas.

おける使用には適していない難点があった。Since the water wheel type stirs the surface layer of the liquid, gas cannot be mixed in sufficiently. The self-priming stirring type is roughly divided into two types: the propeller type and the stirring blade type, but the propeller type is
As seen in No. 21.452, Japanese Patent Publication No. 5B-20294, etc., a propeller is rotated in the liquid and the liquid is transported downward along with the flow of the liquid, but the delivery distance of the liquid mixed with gas is It is short, and the amount of gas mixed in is not large.6 More importantly, when the device is in a stopped state in liquid, the inside of the hollow drive shaft is filled with liquid flowing back up to the liquid level from the air outlet. are doing. A strong force is required to discharge this liquid during startup, but propeller-type engines do not have an effective structure or equipment. Therefore, although it is suitable for use in shallow liquid areas, it is not suitable for use in deep liquid areas.

。The stirring blade type, as seen in Japanese Patent Publication No. 16803/1983, has several stirring blades on the drive shaft and releases gas from their tips, so the amount of gas stirred and mixed in is small. It also had the disadvantage of poor mixing efficiency.Furthermore, the gas injection method using a compression pump lacked the ability to stir the liquid, so it had the disadvantage of insufficient mixing efficiency.

みられない。Regarding how to make the generated bubbles finer, a device used in a special field such as releasing argon gas into molten aluminum has been proposed, for example, in Japanese Patent Publication No. 59-38815. However, no structure has been found that is suitable for use in the general field described above, which is the object of the present invention.
