する。In the aeration #C negative configured as described above, when the motor 81 is driven, the stirring blade rotates via the drive shaft connected to the motor 81, creating a swirling flow in the liquid in the draft tube. urge In addition, the swirling 1/Ic of these several bodies, that is, the eddy current, generates negative pressure in the liquid, sucks the waste from the intake port 85 of the hollow drive shaft, flows down inside the shaft, and passes through the air diffuser port 86 at one end. Released into living fluids. At this time, the bubbles become fine bubbles due to the stirring blade or the vortex. This swirling liquid flows down inside the draft tube 4 at a high flow rate, reaches the bottom of the aeration tank, and then floats over the top of one end of the draft tube, and further flows into the top end of the draft tube. In this way, a swirling flow occurs in the tank as shown by the arrow, and the liquid inside the tank swirls inside and outside the draft tube. At this time, the gas inhaled in the air becomes bubbles, which become finer due to the water flow in the draft tube, improving the oxygen bath survival efficiency, and by providing a DO sensor, the gas suction j4i can be easily adjusted.

Relationship with the amended person's case Patent applicant address: 3-11-1, Shimosakabe, Amagasaki Name: 7 J M, M F4 Kogyo Co., Ltd. . Clear am 1. Title of the invention@Aeration method and device 2. Claims (υ) In an aeration device which supplies gas into several bodies and stirs and dissolves the gas, the aeration m is placed at a desired position in the aeration tank. In an aeration apparatus equipped with an aerator installed vertically and supplying gas into a liquid by forming a low-pressure part at the aeration machine mouth opening, the present invention provides the following features: An aeration method and device for supplying and dissolving air or other gas into the liquid while stirring the waste water, etc., increases the flow rate of the liquid generated by the stirring blade, and increases the stirring flow and suction at the bottom of the tank. The purpose of the present invention is to achieve a uniform aeration effect throughout the tank by creating air bubbles.In other words, the present invention is an aeration device that supplies gas into a liquid and stirs and dissolves it. The gist of the invention is that a cylindrical drum with seven gourds is installed vertically in the center and below the stirring blade of the aerator.Hereinafter, the present invention will be explained based on the illustrated embodiment. 1 is an aeration tank having a required shape and internal volume, and a pedestal 2 is installed approximately in the center of the tank, and an aerator 6 is vertically installed in the tank by this pedestal 2. This aerator 6 is driven by a A hollow stirring shaft 6 is attached to the motor 31 for
2 are connected directly or indirectly, and a stirring blade 33 is fixed to the lower end of this shaft 52, and this motor is placed with a cover 34 outside the shaft, and the stirring blade is connected via the stirring shaft by the drive of the motor. While rotating the p-liquid and thereby stirring the p-liquid,
A device that generates negative pressure in the liquid, sucks air or gas into the liquid along with the vortex of the liquid, stirs and mixes the vortex, and agitates the air or gas bubbles using stirring blades to dissolve them. This hollow stirring shaft is provided with an intake port 35 above the water surface and an air diffuser port 36 near the blade. Further, a cylindrical draft cheep 4 is vertically installed on the pedestal 2 via a bracket 5, and the draft cheep 4 is positioned below the stirring blade, and its upper and lower ends are connected to the inflow of liquid. , to make the outflow more efficient (row 54) widen the end in a morning glory shape. In the illustrated embodiment, the stirring blade is inserted slightly into the upper end of the draft cheep. The diameter and length of this draft cheep 4 are adjusted according to the depth of water in the type 4-i, but the draft cheep length is 1.5 to 3 times the diameter of the stirring blade. It is preferable to define it as a range. Also, the ones in Figures 3 to 5 are the entire motor and drive shaft.
A stirring blade is protruded from the tip of the cover 6, and a stage air volume control valve 7 is provided on the cover near the air intake 0 of the hollow drive shaft. This is the fc embodiment in which the amount of gas sucked into the liquid can be adjusted with the opening/closing section #, and all other parts are the same as the embodiments shown in Figs. 1 and 2.This warm air control valve 7 is provided. Embodiment e In this case, a Do sensor (not shown) is provided in the tank, and the sensor detects the DO value in the tank to control the intake h!. In an aeration device, motor 3
When the well blade 1 is driven, the well blade rotates via a drive shaft connected to the groove, and a swirling flow is generated in the liquid in the drive shaft 7. In addition, the swirling flow or vortex flow of this adult generates negative pressure in the liquid, sucks the gas through the intake port 35 of the hollow drive shaft, flows down within 1M, and passes through the intake port 36 at the lower end, causing the liquid circulation to become a draft. Inside the tube 4, it flows down at a high flow rate and reaches the bottom of the aeration tank, passes the lower end of the draft tape, floats to the top surface, flows into the upper end of the draft tube, and in this way flows into the tank. As shown by the arrow, the liquid in the tank becomes a swirling flow and swirls inside and outside the draft tube.At this time, the gas sucked in by the aerator does not form bubbles, and the water flow inside the draft tube becomes microscopic. By installing a sensor, the amount of gas suction can be adjusted to the J7 fiij 4i. According to the present invention, a single aeration machine is installed vertically at the desired XM, - of the aeration tank. Then, a cylindrical trat tube is installed so that the stirring blade of the aerator is interposed, the gas supplied into the liquid is atomized, and the liquid is sucked from the upper end of the draft tube, and the inside of this gourd is It has the advantage of providing a uniform aeration effect throughout the tank because it is designed to flow in and discharge from the bottom end. 4.
