Description

High efficiency micro bubble dissolved oxygen equipment

The present invention relates to a high-efficiency micro-bubble dissolved oxygen device, and in particular to a high-efficiency micro-bubble dissolved oxygen device developed mainly for improving the dissolved oxygen content in deep water areas of fish ponds.

Taiwan is an island-shaped country surrounded by the sea. This unique environment has created a considerable aquaculture industry in Taiwan. In the land-based aquaculture industry, the oxygen content of the fish pond water has a great impact on the health, survival rate and feed conversion rate of the fish in the pond. The higher the oxygen content of the pond water, the healthier the fish and the higher their disease resistance, thus greatly increasing aquaculture profits.

The current ways to provide dissolved oxygen in fish ponds are as follows:

1. Water pumping wheel: One of the companies has developed a new patent No. M279182 in the Republic of China. When the motor is started, the driving helical gear is rotated synchronously to drive the connected driven helical gear and the gear shaft to rotate, which can drive the water pumping blades of the water pumping wheel to pump water. Moreover, a small horsepower motor can drive the two connected driving helical gears and the driven helical gear to operate. Waterwheel, but the above structure can only improve the dissolved oxygen content on the surface of the pool water, and the dissolved oxygen content in the deep pool is not increased. Moreover, the blade-type flapping not only causes noise that affects the growth environment of aquatic organisms, but also easily harms aquatic organisms when the flapping speed is too high, causing unnecessary losses. In addition, this method requires a large voltage to be provided by the shore, which is not only dangerous but also easily affected by power outages.

2. Windmill device: Another industry has developed a high-efficiency air-pumping windmill device with Republic of China patent No. 141439, which is mainly composed of a fan blade wind receiving unit, an air compression unit, and a tail wing orientation unit. The technology uses a simple blade structure to fully absorb wind power to exert its operating function and drive the rear compressor to compress and store air to provide cylinder pressure to compress air and pump it into the water to increase the oxygen density in the fish pond. The above-mentioned wind power generation will generate unstable energy due to seasonality or wind force, which is easy to cause intermittent oxygen supply and lead to uneven oxygen density.

3. Submerged type: Another operator has developed a submerged pressurized oxygen supply machine for water treatment with Republic of China patent No. 194375. It uses a hollow inverted cone-shaped pressurized air intake pipe that is larger at the top and smaller at the bottom, and a pressurized air intake mechanism linked to a rotary machine to generate a strong air suction force, achieving sufficient mixing of air and water and injecting it into the water. However, this method still produces a loud noise when the outer blades hit the fish pond, affecting the living space of fish.

4. Submersible motor: A submersible motor pressurized dissolved oxygen pump with Republic of China patent No. M313423 has been developed by an industry. It is an improvement on the structure of submersible motor pumps. The main structure includes a submersible motor, a shaft seal seat, an air suction pipe seat, a cylindrical squirrel cage axial flow fan attached to the hollow inner shaft, a spiral exhaust fan, and a propeller attached to the outer shaft. Its characteristic is that the air on the water surface is directly poured into the water through the powerful suction motor of the invention, and the blades installed outside disturb the water in the fish pond to generate water flow, so that the air and water are mixed to increase the oxygen content. However, this method still requires a large voltage to drive the motor to operate, which causes power consumption problems.

5. Mobile green energy: The mobile green energy fish pond aerator with the Republic of China patent No. M461318 uses a pumping motor to pump the fish pond water away from the water surface and spray it into the air. The design of the atomizing nozzle allows the sprayed pond water to be sprayed into the air in an atomized manner to increase the contact area between water and air and increase the oxygen content of the water. At the same time, the falling water mist can fall on the solar panels to reduce the surface temperature of the solar panels. In order to improve the conversion efficiency of the solar panels, a power motor is designed to allow users to control the movement to a designated location for oxygenation through wireless means. However, the above structure can only improve the dissolved oxygen content on the surface of the pool water, and the dissolved oxygen content in the deep pool is not increased. In addition, the mobile green energy fish pond aerator cannot increase the oxygen content and move when the weather is bad.

In response to the above-mentioned development of new improved structures, other companies have also developed a variety of water bath oxygenation equipment used in water treatment (such as sewage treatment, aquaculture, etc.), such as the known technical literature: Announcement No. 056594 "Floating Circulation Wide-Angle Air Transport Water Truck", Announcement No. 066928 "Gush-type Water Pumping Truck", Announcement No. 163849 "Improved Structure of Farm Water Pumping Truck", Announcement No. 177 No. 992 "New Structure of Water Pumping Cart for Aquaculture", No. 189930 "New Structure of Oxygen Supply Water Pumping Cart for Aquaculture", No. 228051 "Structure of Oxygen Supply Water Pumping Cart for Aquaculture with Drainage Function", No. 342599 "Structure of Water Pumping Cart for Aquaculture"...etc., but they are also unable to achieve the effect of improving the efficiency of the present invention in a large area to increase the oxygen in the fish pond and purify the water quality.

The inventor of the present invention has known that the conventional water pumping motor has the above-mentioned shortcomings, and therefore came up with the idea of creating the present invention. After much discussion and trial production of samples, as well as many revisions and improvements, the present invention was finally launched.

The present invention provides a high-efficiency micro-bubble dissolved oxygen device, comprising: a motor; a pipe frame, the pipe frame is assembled on the motor; and at least one high-efficiency dissolved oxygen generating mechanism, the high-efficiency dissolved oxygen generating mechanism is a structure capable of generating a venturi effect and a spiral pressurization action, the motor is arranged in a fish pond, the motor guides the water in the fish pond and then drives the flowing water to sequentially pass through the pipe frame, and then enter the space of the high-efficiency dissolved oxygen generating mechanism, and cooperates with the dual pressurization method of the venturi effect and the spiral pressurization in the high-efficiency dissolved oxygen generating mechanism, so that the external air is sucked in by negative pressure and broken into smaller micro-bubbles, which are dissolved in the flowing water and then guided into the water in the fish pond.

Please refer to Figures 6 to 8 for schematic diagrams of the use of the high-efficiency micro-bubble dissolved oxygen equipment in a fish pond, wherein the procedures are carried out in sequence as follows: the first is a pumping procedure: the high-pressure air supply and waterproof motor body 11 of the motor 10 is set in the middle water area at the bottom of the fish pond, and the water in the fish pond is pumped from the bottom frame 12 by the motor body 11 of the motor 10; the second is a guiding procedure: the interface 111 of the motor 10 drives the guided water flow to flow to the vertical main pipe 21 and the horizontal main pipe 22 of the pipe frame body 20 and the two covers 24 in sequence, so that Each cover 24 makes the internal flow pipeline a closed space, so the water in the fish pond is drawn to flow toward each elbow 23 and then enter the high-efficiency dissolved oxygen spray tube 31 respectively; the third is the first pressurization procedure: the second end 322 of the first air intake elbow 32 is connected to the outside to provide negative pressure air, which is sequentially sucked into the first end 321 of the first air intake elbow 32 and then into the 36 small apertures of the air column plate 3121 of the second joint end 312 to divide the air, pressurize and break it to form micro bubbles, and then guide the first pressurized micro bubbles into the gas collecting tank 312 ...

The first air inlet bend 322 is connected to the outside to provide negative pressure air, which is inhaled into the first end 321 of the first air inlet bend 32 and then into the 36 small apertures of the air column plate 3121 of the second joint end 312 to separate and pressurize the air to break it into micro bubbles, and then introduce the first pressurized micro bubbles into the air column plate 3121 of the second joint end 312. The water flows into the gas collecting tank 3122, where the water flows through the first aperture 3111, the second aperture 3112 and the third aperture 3113 in the first joint end 311 of the high-efficiency dissolved oxygen spraying tube 31 in sequence. Since the diameters of the first aperture 3111 and the third aperture 3113 are larger than the second aperture 3112, the different cross-sectional area designs produce a venturi effect, thereby pressurizing the flowing water to form a second pressure velocity change, and the micro-bubbles in the gas collecting tank 3122 are driven by the pressure velocity to be sucked in by the negative pressure and broken into smaller micro-gases. The water outlet 313 of the bubble jet is provided with multiple staggered left and right spiral grooves 3131 to generate spiral pressurization.

The floating plate frame 40 is provided with two floating plates 41 and a frame 42. The motor 10 is a gear pump. The motor body 11 of the motor 10 is installed in the frame 42. The pipe frame 20 is installed horizontally at the bottom of the two floating plates 41 in the fish pond. The motor body 11 of the motor 10 increases the oxygen content of the fish pond. The water in the fish pond is extracted from the bottom frame 12 through the pipeline, and the interface 111 of the motor 10 drives the water flow to the vertical main pipeline 21 and the horizontal main pipeline 22 of the pipe frame 20 and the two covers 24 in sequence. Since each cover 24 makes the internal flow pipeline a closed space, the water flow in the fish pond is extracted to flow toward each elbow 23 and then enter the high-efficiency dissolved oxygen injection pipe 31 respectively. The second end 322 of the first air intake elbow 32 is connected to the outside to provide negative pressure air to be sucked into the first end of the first air intake elbow 32 in sequence. After the air is divided and pressurized to break the air into micro bubbles, the micro bubbles are guided into the gas collecting tank 3122. The water flows through the first aperture 3111, the second aperture 3112 and the third aperture 3113 in the first joint end 311 of the high-efficiency dissolved oxygen spraying tube 31 in sequence. Since the diameters of the first aperture 3111 and the third aperture 3113 are larger than the second aperture 3112, the different cross-sectional area designs generate Venturi. The micro-bubbles in the gas collecting groove 3122 are guided by the pressure-increasing speed to be sucked in by the negative pressure and broken into smaller micro-bubbles, which are then ejected from the water outlet 313. The micro-bubbles in the gas collecting groove 3122 are guided by the pressure-increasing speed to be sucked in by the negative pressure and broken into smaller micro-bubbles, which are then ejected from the water outlet 313. The micro-bubbles in the gas collecting groove 3122 are guided by the pressure-increasing speed to be sucked in by the negative pressure and broken into smaller micro-bubbles, which are then ejected from the water outlet 313. The micro-bubbles in the gas collecting groove 3122 are guided by the pressure-increasing speed to be sucked in by the negative pressure and broken into smaller micro-bubbles, which are then ejected from the water outlet 313. The micro-bubbles in the gas collecting groove 3122 are guided by the pressure-increasing speed to be sucked in by the negative pressure and broken into smaller micro-bubbles, which are then ejected from the water outlet 313. The air bubbles are sucked in by the negative pressure and broken into smaller bubbles, which are dissolved in the flowing water and then introduced into the fish pond by the high pressure, thereby achieving a high efficiency and wide range of oxygen increase and water purification in the fish pond, and the floating plate frame 40 is able to move in the fish pond, thereby achieving a large range of dissolved oxygen efficiency increase as the main effect; please refer to Figures 13 and 14, in which a high efficiency dissolved oxygen generating mechanism 30 is directly arranged on the interface 111 of the motor body 11 of the motor 10, and the motor body 11 of the motor 10 is arranged on the floating plate The frame 40 is pressurized by the motor body 11 to extract water from the fish pond from the bottom frame 12 where it is connected to a pipe body, and driven by the interface 111 of the motor 10 to flow to the high-efficiency dissolved oxygen spray pipe body 31. After entering the high-efficiency dissolved oxygen spray pipe body 31, the second end 322 of the first air intake elbow 32 is connected to the outside to provide negative pressure air, which is sequentially sucked into the first end 321 of the first air intake elbow 32 and then to the 36 small apertures of the air column plate 3121 of the second joint end 312 for air segmentation and pressurization to break up the micro bubbles. The first pressurized microbubbles are guided into the gas collecting tank 3122, and the water flows through the first aperture 3111, the second aperture 3112 and the third aperture 3113 in the first joint end 311 of the high-efficiency dissolved oxygen spraying tube 31 in sequence. Since the diameters of the first aperture 3111 and the third aperture 3113 are larger than the second aperture 3112, the different cross-sectional area designs produce a venturi effect, thereby pressurizing the flowing water to form a second pressurization speed change, and then the microbubbles in the gas collecting tank 3122 are guided to increase the pressurization speed. The micro-bubbles are sucked in by the negative pressure and broken into smaller micro-bubbles, which are ejected toward the water outlet 313. The micro-bubbles in the air collecting groove 3122 guide the pressurization speed to drive the micro-bubbles to be broken into smaller micro-bubbles, which are dissolved in the flowing water and then led to the fish pond at high pressure, thereby achieving the main effect of increasing the area of the fish pond with high efficiency and large range.

After the bubbles are formed, the microbubbles generated by the first pressurization are guided into the gas collecting tank 3122, where the water flows sequentially through the first aperture 3111, the second aperture 3112 and the third aperture 3113 in the first joint end 311 of the high-efficiency dissolved oxygen spraying tube 31. Since the diameters of the first aperture 3111 and the third aperture 3113 are larger than the diameters of the second aperture 3112, the different cross-sectional areas are set. The design generates a venturi effect, which in turn causes the flowing water to be pressurized to form a second pressure velocity change, and the micro-bubbles in the gas collecting groove 3122 are driven by the pressure velocity to be sucked in by the negative pressure and broken into smaller micro-bubbles, which are ejected toward the water outlet 313. The inner part of the water collecting groove 313 is provided with a plurality of staggered left and right spiral grooves 3131 to generate a spiral pressurization action. The micro-bubbles in the gas collecting groove 3122 are driven by the pressure velocity to be sucked in by the negative pressure to form smaller micro-bubbles. The air bubbles sucked in by the negative pressure are broken into smaller bubbles and ejected toward the water outlet 313. A plurality of staggered left and right spiral grooves 3131 are provided inside to generate spiral pressurization. A double pressurization method is formed to dissolve the air bubbles sucked in by the negative pressure into the flowing water and then lead them into the fish pond under high pressure, thereby achieving the effect of increasing the oxygen in the fish pond and purifying the water quality in a large area with high efficiency in the fish pond.
