Description

2366526 Water Pressure Oxygenating Device

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to the structure of a water pressure 5 oxygenating device, more particularly to a structure of a water pressure oxygenating device utilizing the pressure of a water pump which diverges the water into several branch pipes, and then to everywhere in the pool.

Description of the Prior Art

In the conventional cultivating ponds (or water tanks) that provide 10 oxygenating devices used for cultivating fishes along the coast or in the inland fresh water pisciculture and interior cultivating aquarium, currently uses an impeller waterwheel aeration method for the ponds, and waterwheels in the shape of a radiant spoon are generally used. By the continual rotation of the waterwheel, splashes are formed on the water surface of the pond in order to 15 oxygenate the water and improve the water quality. However, such doing is limited to certain local points on the water surface. For the aquarium, regardless of large or small ones, it has two pumps, one for extracting water to the filter tank for removing impurities in the water, and the other is for pumping air into water to produce splashes, and provides oxygenated water for 20 the cultivated organisms. Neither of the above can take care of the oxygen supply for the whole area, and obviously using two pumps is a waste of energy consumption.

The popular implementations of the conventional oxygenated devices generally have the following shortcomings.

1. General impeller waterwheel aeration method can only cover the water surface and is limited to a point but not the whole area including that is deep down in the water.

2. General extracting aeration method generally produces noise pollution, affects the landscape, and expedite the water vaporization and water loss.

5 3. General air pump oxygenating devices directly pump air into water, and easily generate hot air for long-time use, that in turn raise the water temperature. Since there is no water filter device, the polluted air will be brought to the water and contaminate the water or hurt the cultivated organisms.

10 4. The foregoing methods or device cannot be used for the overall flow of the water in ponds (aquaria), and generally cannot provide the average oxygen supply for cultivated organisms.

5. The foregoing methods or device cannot cope with the overall chemical spreading, and it is one of the ma or shortcomings in 15 cultivation.

6. The foregoing methods or device waste resources or material (additional pumps, energy consumption), cannot attain the overall oxygenation effect and may have the risks of electricity leakage which will damage the cultivated organisms.

20 In view of the shortcomings and inconvenience of the prior art mentioned above, which are the subjects of improvements for a long time, hence the inventor of the present invention based on years of experience accumulated from the engagement in the related industry conducted extensive research to resolve the foregoing shortcomings and invented the present 25 invention.

Therefore, the primary objective of the present invention is to provide an improved structure of a water pressure oxygenated device comprising only four portions, namely water pump installed in the land, water splitter, branch water pipe and mist producing chamber, and air filter supplier. It forms an overall structure and is deposed according to the real situation (such as the size of 5 ponds or aquaria). There are artificial cultivation businesses along the seacoast or the inland rivers and lakes in different countries, and they uses the foregoing conventional methods and bears the shortcomings as mentioned above. The present invention is definitely a major contribution to the world cultivation industry.

10 To make it easier for our examiner to understand the objective of the invention, structure, innovative features, and performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer to Figures 1. The water pump I is deposed on the land 7 near the periphery of the pond and secured to a fixed water pump base plate 12, having a small housing 11 above the water pump for its protection. The feeding 10 pipe 14 is supported by the water pipe supporting plate 121 and is suspended in water without touching the bottom of the pond to suck water in the pond. A water-feeding filter is deposed at the end of a feeding pipe for filtering any possible existing sandstone, grass, leaf, small fish, shrimp, or other microorganisms, which gives the first filter for the pond. Water is ejected from 15 the water pump after pressure is added, and a pipe leads the water to a water purification filter tank 132 having a premium filter materials. The water filtered from the filter tank feedbacks to the pond through the bottom of the tank, and circulates the water for continual use for the pond, and also keeps the pond water clean. The water sucked in is again sent to an output pipe 16 by the 20 water pump land then directly to the branch water splitter 2. Instantly, the water passes through the water splitter cover 22 which has several connecting pipe 23 for branch water pipes respectively flows into each branch water pipe 3 and then to a mist producing chamber 4 at the end of the branch water pipe.

After passing through the pressure binder 42 of the chamber, which couples to 25 an air feeding valve and fresh oxygen supply pipe 5, air is sucked and mixed by circulation with the water in the mist producing chamber 44 by the friction of water flow, and the water is forced to the dispersion nozzle 45 and ejected through the ejecting hole 46 and dispersed from side to side according to the specially designed flat fan-shaped distribution. Such fan-shaped distribution helps to expand the coverage of ejected water in the pond, and produces the water flow due to its addition and impact. Therefore, it produces oxygenated water, and provides sufficient oxygen in average for the cultivated organisms in the entire pond (aquarium) via several mist producing chambers 4 deposed at 5 the appropriate locations. It sure improves the cultivation business for excellent cultivated products and its production as well.

For the mechanism of the present invention, the pump is installed on the land (near the side of the pond), which facilitates maintenance and repair. In case electricity leakage occurs, this safe arrangement will not kill the cultivated 10 organisms with electric shocks. Slight modification for the pump, which has a water-feeding pipe 14 having a filter mask 15 at the front end of th& water feeding pipe 14, allows water to be ejected by the pump and split into two pipelines of which one is the filtered water pipe 13 for transporting part of the water into a purification filter tank 132, and then to the pond for storage after 15 filtered; there is a output water control valve 131 deposed in the middle of such water pipe used for adjusting the control of the output water flow. The purification filter tank 132 is a rectangular box having an open side on its upper side for receiving the incoming water, and having regular filter material inside the tank, and the bottom is in the form of a net for holding the filter material 20 and allowing the water to pass into the pond through it. The other split pipeline is an output water pipe 16, and the water sucked in through the pump when pressure is added and passes into the output water pipe 16 and then directly to the water splitter 2 and further distributes to different branch water pipes for use.

25 The splitter 2 according to the present invention is a pipe that is secured to the external end of an output water pipe 16 having screw threads with sealed washer on it and is coupled with the water splitter cover 22 by screws and formed a whole piece. There are a plurality of connecting pipes 23 of the branch water pipe having the tallest one in the middle that facilitates the installation of the branch water pipes. The connection of such connecting pipe and branch water pipes 3 securely couples each of the branch water pipes to the splitter by a branch water pipe screw board 5 1. The total internal diameter of the branch water pipes 3 cannot exceed the diameter of the output water pipe to 5 ensure the constant water pressure and maintain the water pressure for the mistproducing chamber.

The mist-producing chamber 4 according to the present invention is a structure made of metal (steel) or plastic and in the shape of inverted "T" and the pipes on its upper section are coupled to fresh air supply pipe 5, and the pipes along the horizontal side with its inward end coupled to a branch water pipe 3, and the outward end coupled to a dispersing nozzle 45 that constitutes the structure of an overall mist-producing chamber 4. A vertically downward inhaling valve 41 is deposed according to the internal diameter and its location just forms a bottleneck with a protruding ringed pressure binder 42 at the internal diameter of the pipe. It pushes the water transported from the branch pipes and increases its pressure. Since the inhaling valve is about half of the area of the inlet of the fresh air supply pipe 5, it sucks the air into the air/water mixing mist-producing chamber 44 by the friction created by the strong water spout and the guidance of the inhaling valve. The front path of the extended segment of the air/water mixing mist-production chamber has a prominent ringed bar for reducing the internal diameter of the pipe and forms an air/water mixing mist-producing chamber 44 in the middle of the rear pressure binder.

The mixture of the air and water formed by the rear pressure binder and the inhaling valve 41 is ejected from the rear pressure binder 42. Due to the blocking by the bottleneck of the front pressure binder 43, the mixture will naturally whirl inside the mist-producing chamber 44 to completely mix the air and water together and the water ejected is the mixture with oxygenated water.

To expand the area of the ejection, a dispersion nozzle 45 is added to the ejecting outlet, and the dispersion nozzle has a structure of short tube member and has a circular shape at its lower section with screw thread within the internal pipe for easy connection with the ejecting pipe of the mist- producing chamber; its front section is flat and has a plurality of ejecting holes 46 in its interior. Such holes are constructed according to the fan (or circular) shaped 5 nozzle from side to side and distributed as a whole piece fan shape in order to eject the mixture in a fan shape that covers a larger area for the dispersion. It attains the purposes of supplying oxygenated water and increases the water mobile activities function. To strengthen the oxygen supply, it incorporates a connected body of two or more consecutive mist- producing chambers (as 10 shown in Figure 4) for mixing more fresh air into the water and fully supplying sufficient oxygenated water to the pond.

The air filter supplier 6 according to the present invention has a structure of using a small circular airbag (similar to the swimming buoy) filled with air or made of polylon material. This structure flows in the water having a ringed 15 groove at its internal surface for installing the chamber connection tenon 611. The hollow lower section of the air filter supplier is a purified air storage chamber 62, and a protruding member is deposed inside the periphery of the chamber, which is an internal ringed platform to support the circular activated carbon filter material. The upper periphery of the device has several square air 20 inhaling holes 64 and there is a cylindrical dust filter 66 at this section for performing the first filtering of the air sucked into the air supplier. A circular chemical adding cup (wide at top and narrow at the bottom) or funnel 67 in the section for adding cultivation chemicals to this cup before sending it into the pond. A small hole is deposed at the bottom of the suspending leg of such cup 25 or funnel allowing the chemicals to slowly drop into the pond with rhythm of a long time, and makes the chemical even and adds small quantity of it, and such hole can be selectively plugged according to the demand quantity of the chemicals (small plug rods are prepared for this purpose). If there is a large demand for the chemicals, all of the plug rods can be removed, and the inverted conical cup is used in order to prevent any blocks to the airflow. After all elements are installed as a piece, a decorative device 691 can be installed on each air filter supplier, such as a duck, a lotus, or the like, and finally a triangular protection cover 69 is added. When everything is ready, a central 5 fixing screw is inserted to the center of the bottom to fix screw nut 682 of the axle rod and screwed to be a whole piece air filter supplier. The bottom of such device has a connecting pipe directly connected to the fresh air supply pipe 5 that is respectively connected to each mist- producing chamber 4 for supplying fresh air.

10 The air filter supplier 6 according to the present invention can be installed on the land near the pond for the application on places such as a long narrow ditch or pond. The fresh air supply pipe 5 can be installed along with the output pipe (as shown in Figure 6), and the number of mist-producing chambers can be installed according to the consumption in the ditch, and 15 similarly it can provide the overall oxygenated water effect for the cultivation ditch.

Therefore, in summation of the above description, the improved structure of the present invention at least has the following merits:

1. The present invention only uses a water pump, which saves material 20 and energy (electricity) and maintenance and repair manpower.

2. The present invention generally increases the oxygenation and water mobility of the pond (aquarium), reduces water temperature and maintains it in a good range, and distributes water everywhere in the pond to attain the functions of overall oxygen supply and 25 mobile current.

3. It increases dissolved oxygen, provides biochemical oxygen and chemical oxygen, quickly decomposes organic matters, removes stinging odors or poisonous gases, and prevents diseases caused by flingus infection.

4. If chemicals are needed, it can be added via the air filter supplier and distributed to each of the mist-producing chambers through the 5 fresh air supply pipe; and after mixing, it is ejected into the water of the pond. Such arrangement allows an evenly distributed, widely spread, appropriate amount, fast, convenient, efficient, direct, and excellent effective way to provide oxygenated water.

5. The present invention refills fresh water, and achieve a quick 10 cooling action through the water passage in the fresh air supply pipe in the pond. Therefore the water temperature of the water entering the mist-producing chamber is the appropriate temperature for the pond. After ejecting the mixture, it produces excellent oxygenated water with appropriate temperature. It efficiency, convenience, and 15 consistence are well accepted by the cultivation industry. The air filter supplier according to the present invention is artistic to t he observer since each set has a decoration such as a duck, a goose, a lotus, or the like which beautifies the pond quite a bit.
