[0009]

[Embodiment of the invention]

 As shown in FIG. 2, the apparatus according to one embodiment of the present invention has a ventilation pipe section A, a float B, a one-way valve C, a bubble-forming board D, and a weight E. The ventilation pipe section A includes an upper stage 1 and a lower stage 2. A hook hole 11 is provided at an upper end of the upper stage 1. The rope connected to the hook hole 11 is connected to a floating body on the liquid surface. A side hole 12 is provided on a side surface of the ventilation pipe portion A 1, and an air pipe is connected to the side hole 12.

An engagement surface 21 is formed on an outer peripheral edge of the lower end of the lower stage 2. In this engaging surface 21, the bubble forming film 3 is locked by the fixing piece 22 and the fixing component. The upper and lower tiers 1 and 2 of the ventilation pipe part are joined by a screwing method, and below the lower tier 2, a bubbling board D and a ventilation distribution pipe 4 are screwed in order. In the cross section of the bubbler D, several reinforcing rods 31 are provided, and screw holes 32 are provided at appropriate positions.

After the assembling, the outlet 43 of the ventilation pipe 4 is installed below the two screw holes 32 of the bubbling board D.

The float B is installed on the upper stage 1 of the ventilation pipe section A. Further, the one-way valve C is installed in the two screw holes 32 installed in the bubble-forming board D, and fitted into the outlet 43 of the ventilation pipe 4. The one-way valve C prevents the liquid from flowing into the vent pipe section A.

[0013] Thus, the pressure required by the air pump in each use is reduced. The lower part of the outlet 43 forms a horizontal part 41 and a vertical part 42, so that the air of the part is located below the one-way valve C. Therefore, the buoyancy of the gas in the horizontal portion 41 and the vertical portion 42 can further reduce the pressure required by an air pump or another air supply container during air supply.

Several reinforcing rods 31 are installed in the cross section of the bubbling plate D to obtain the strength and hardness required by the bubbling plate D. The bubble-forming film 3 is a film body having extremely minute exhaust holes, and is installed on the upper edge of the bubble-forming board D. The center position is just on the engagement surface 21 of the lower part 2 of the ventilation pipe part A, the bubble fixing film 3 is locked by the annular fixing piece 22 and the fixing component, and the annular packing 51 and the fixing component are further fixed. The bubble-forming film 3 is fixed by use. A storage space 52 is formed between the bubble forming film 3 and the bubble forming board D.

The weight E includes a support frame 61 and a weight 62. The support frame 61 is installed at the bottom of the bubble forming film 3, and the weight 62 is installed at the end of the support frame 61.

Next, as shown in FIG. 3, at the time of use, the hanging type liquid / gas mixing device is put in water, the motor is started, the gas is caused to flow into the air pipe, and the gas is introduced into the air pipe section A through the side hole 12. , And further into the ventilation pipe 4. The horizontal portion 41 and the vertical portion 42 of the ventilation branch pipe 4 form an air-filled space, can pass through a one-way valve C installed at the outlet 43, and can enter the housing space 52. By correspondingly providing the bubbler D and the bubbler film 3, the air is subdivided and the oxygen is advantageously dissolved in water. The gas forms a large amount of small bubbles through the bubble film 3 and rises slowly.

When the weight of the bubbler D is sufficient (for example, when it is made of steel), it is not necessary to further use a weight. The float B can provide buoyancy for improving the overall structure.

When the suspended liquid-gas mixing device is subjected to an external force and tilts, the improved buoyancy provides a restoring torque and can be restored to the original position. In this way, the foaming surface of the bubbler D maintains the upward facing state forever.

When the weight of the bubbler D is not sufficient (for example, when it is made of a plastic material, etc.), it is submerged in a liquid using a weight E. At the same time, the floating B can stabilize the entire structure.

When the suspended liquid-gas mixing device is subjected to an external force in the liquid and tilts, the float B provides buoyancy, and the weight E provides downward gravity. In this way, the two correspond to each other, so that the suspension type liquid / gas mixing device generates a torque for restoring the original position, and the foaming surface of the bubbler D is kept forever upward.

The float B has a design integrally formed with the upper section 1 of the ventilation pipe section A, but can be assembled separately after being manufactured separately. Although there is no particular limitation on the material, it is important that the material does not react chemically with gas or liquid and has a specific gravity smaller than that of liquid. Further, although there is no strict restriction on the shape, the total buoyancy must be able to be concentrated at the center point of the ventilation pipe section A (the simplest is an axisymmetric structure, and the cross section is circular).

The horizontal part 41 and the vertical part 42 of the ventilation pipe part A prevent the liquid from flowing back from the storage space 52 of the bubbler board D to the ventilation pipe part A and the air filling space of the ventilation distribution branch pipe 4. The one-way valve C installed at the end outlet 43 is simple in structure and provides an effective backflow prevention function.

In the cross section of the bubbler D, there are several reinforcing rods 31, which provide the strength and hardness required by the bubbler D, and which the float B provides. The recovery torque can be used to hold the foaming surface of the bubbler D upwards (if the bubbler D was soft, the recovery torque would lose effect).

The bubble forming film 3 is fixed to the upper edge of the bubble forming board D. The material and the size of the pores of the bubble forming film 3 are selected according to actual needs. The outer shape of the bubbled film 3 and the bubbler D is also not strictly limited, like the float B, but the best and simplest shape is still circular.

The gas is supplied from a floating air supply device on the liquid surface (air supply is also possible on the shore), through an air inlet pipe, a ventilation pipe section A, a bubble plate D, and a ventilation branch pipe 4 to form a bubble plate. D enters into the accommodation space 52 of D, and then is made into a large amount of small bubbles by the bubble forming film 3 and floats upward. The weight of the rope and the weight E on the ventilation pipe section A can adjust the depth of the gas-liquid mixing device in the liquid.

Further, since the rope is made of a soft material, external force (wave wind) on the liquid surface can be effectively isolated.

The float B and the weight E at the bottom of the bubbler D provide a recovery torque for stabilizing the apparatus, so that there is no need to fear the influence of external force coming from the water bottom. Upright forever.

The one-way valve C can prevent liquid backflow during air supply, closes the air entry route, and can significantly reduce the load on the air pump during air supply. The one-way valve C is installed in two screw holes 32 installed on the bubble-forming board D, and is fitted into the outlet 43 of the ventilation pipe 4. The one-way valve C prevents liquid from flowing into the ventilation pipe section A, and reduces the pressure required by the air pump each time it is used. Since the vertical portion 42 and the horizontal portion 41 are located below the outlet 43, the air in the portion is located below. Therefore, the buoyancy generated in the gas in the vertical portion 42 and the horizontal portion 41 can further reduce the pressure required by an air pump or another air supply device during air supply.

In the cross section of the bubbler D, several reinforcing rods 31 are provided to provide the required strength and hardness of the bubbler film 3.

As shown in FIGS. 4 and 5, the device of the present invention can be another embodiment.

The structure of another embodiment includes a vent tube A, a float B, a one-way valve C ′, and a bubbler D.

The ventilation pipe section A is provided with an upper stage 1 and a lower stage 2. A top end of the upper stage 1 is a hook hole 11, and a rope connected to the hook hole 11 is connected to a floating body on the liquid surface. A side hole 12 is provided on a side surface of the ventilation pipe A, and an air pipe is connected to the side hole 12.

A float B is provided below the side hole 12 so as to be connected to the ventilation pipe portion A, and is connected between the lower portion 2 of the ventilation pipe portion A and the bubble plate D, and can be combined very easily. Install an effective one-way valve C '. A hook 61 'is provided at the bottom of the bubbler D for hanging a heavy object.

At the center of the bubbling plate D, the lower part 2 of the ventilation pipe section A is connected to the ventilation shaft 23, and the ventilation shaft 23 is provided with a unidirectional valve C ′. A hole 24 is provided on the ventilation shaft 23 so that the gas flows out from the ventilation pipe A. A large amount of small bubbles are generated by the bubble-forming film 3 on the surface of the bubble-forming board D, and rise slowly.

In the cross section of the bubbler D, several reinforcing rods 31 are provided to provide the required strength and hardness of the bubbler D. Thus, the foaming surface of the bubbler D can be held upward using the recovery torque provided by the float B. The material of the bubble forming film 3 and the size of the pores are selected according to actual needs. The outer shapes of the bubbled film 3 and the bubbler D are not strictly limited, as in the case of the float B, but the best and simplest shape is still a circle.

The gas is supplied from a floating air supply device on the liquid surface (air supply is also possible on the shore) from an air entry pipe, a ventilation pipe section A, a bubble plate D, a ventilation distribution pipe 4, a unidirectional valve C ′, The gas enters the bubbler D through the hole 24 on the ventilation shaft 23 on the bubbler D, and subsequently, a large amount of small bubbles are formed by the bubbler film 3 and float upward. The rope on the vent pipe section A can adjust the depth of the gas-liquid mixer in the liquid.

In addition, since the rope is made of a soft material, external force (wave wind) on the liquid surface can be effectively isolated.

The weight of the floating B and the bottom of the bubbler D provide a recovery torque for stabilizing the structure, so that there is no need to fear the influence of an external force coming from the water bottom, and the foaming surface of the bubbler D is permanent. It is upward.

The one-way valve C ′ prevents the liquid from flowing backward when the air supply is stopped, and blocks the air entry route. As a result, the burden on the air pump during air supply can be reduced. The gas flowing into the bubble forming film 3 becomes a large amount of small bubbles, and increases the reaction area between the gas and the liquid and the time.

In addition, since it has a self-stabilizing adjusting force, when installed in liquid, there is no need to fear the effects of external forces such as wind waves, and the bubble-blowing surface of the bubbler can be held upwards. Simple, easy to maintain, and efficient. Furthermore, since it is only necessary to supply gas by an air pump, it leads to relatively power saving, and the operation is the same at the time of a power failure. Need to connect.

The installation of the ventilating branch pipe, the bubbling plate, and the one-way valve favorably and effectively prevent the backflow of water into the vent pipe section, and the reaction pressure of water in the storage space below the bubbling membrane. The pressure required by the air pump can be reduced, the service life of the pump can be extended, the efficiency is high, and the power saving effect is extremely high.
