Abstract

PURPOSE:To produce continuously fine bubbles in water by placing many water supply pipes communicated with a pump in parallel under the water surface in a fixed area of a water tank, etc., and facing the opening port of a spouting pipe attached to the appropriate position of the water supply pipe to the discharge port of an air supply pipe. CONSTITUTION:Many water supply pipes 3 communicated with a pump P are placed in parallel under the water surface in the fixed area in a water tank, a fish preserve, etc., and the lower part of an air supply pipe 4 is fixed to the respective water supply pipe 3. A float F equipped with an air port (a) is attached to the upper part of the air supply pipe 4, and a nozzle (n) furnished to the water supply pipe 3 is faced to the spouting port (d) which is opened at the lower part of the air supply pipe 4. In this way, fine bubbles are produced at all times in the water, and the sufficient agitation due to the convection in water can be obtained. The time and efforts required for setting a prime mover can be remarkably reduced in comparison with the existing apparatus wherein the prime mover is set over or under the water surface. In addition, immeasurable damages to fishes and shellfishes due to the local agitation of water can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is suitable for purifying water and cultivating fish and shellfish by making the air bubbles released into the water fine within a certain area, and has a simple structure as a whole. The present invention relates to a fluid stirring device capable of stirring water.

Water h! The water that is stored in a certain area, such as a fish tank or an aquaculture pond, is transformed into an air-like gaseous substance and is released into the sky.

Conventionally, as a means to obtain an environment suitable for water purification and fish and shellfish farming, for example, (1) an electric motor set at a fixed position above the water surface rotates a rotating shaft at high speed' (200θ to 200θ rotations/min); Then, while water is passed between the rotating shaft and the outer cover set with a gap of PJr, air is blown out from below the inner side of the rotating shaft, and the air and water are mixed. There is a type of agitation type, but in such type, since the rotating shaft rotates at high speed, it is often difficult or impossible for the air to form or maintain a fine bubble state. A prime mover like an electric motor,
Because it is necessary to install above the water surface of aquariums, cages, aquaculture ponds, etc., there is a nearby prime mover J! It is difficult to say that it is an appropriate stirring means because it causes real damage due to the movement of the mixture (11).
) If the electric motor is connected underwater, there will be almost no noise damage caused by driving the electric motor, but it will require complete sealing for the electric motor, rotating shaft, etc., and smooth driving will be required. Because it requires the use of a lubricant, it is difficult to avoid complicating the structure, and the lubricant may unexpectedly leak into the water due to vibrations when the motor is running, contaminating the water, or causing the lubricant to a of
Depending on the type, there is a risk of damaging seafood, and
In the event of failure of the motor due to overload operation or overheating of the motor, it is difficult to say that this is an appropriate method, as there are disadvantages such as the time required to remove the motor from the water. Therefore, with the intention of correcting the above-mentioned drawbacks, the present invention has been developed by arranging a large number of water pipes connected to pumps under the water surface in a certain area such as an aquarium, a fish tank, or an aquaculture pond. By placing the opening of the ejection pipe installed in the appropriate place facing the outlet at the lower end of the air supply pipe, fine air bubbles are constantly generated in the water, and air is generated. It is an object of the present invention to provide a fluid-throwing shuttle device that can be used satisfactorily, eliminates unnecessary disasters and complicated labor caused by installing the prime mover above or below the water surface, and has an extremely simple overall configuration. It is something to do.

Referring to the drawings below, we will describe a case where this embodiment of the present invention is applied to a water tank T.A joint J is installed below a connecting pipe connected to the discharge pipe of a pump P fixed outside the water tank T.
A suitable number (three in this case) of the water supply pipes 3 connected and branched to the R5' hand J are set in parallel underwater, and an air supply pipe group is connected to each of these water supply pipes at a predetermined interval. The lower ends of the floats F, which have air holes a, are fixed to the upper ends of the air supply pipes q, while the air supply 'f? A nozzle n that is fixed and protrudes from the side of the water pipe 3 is housed inside the spout d formed near the lower end of the float, and the air taken in from above the float F is directed through the nozzle n. It is made fine by the pressurized water that is ejected, and can be ejected into the water pail 1. In addition, in order to prevent the water pipe 3 from shaking in the water,
Suspend g+, 1iIV+ in the appropriate place, and also water t6T,
The bent portions C of the water pipes 3 of both t (1") are brought into contact with the holding rod J attached to the bottom, and the water pipes 3 are prevented from coming close to each other in advance, and the jet from one spout d flows into the water pail. This is to prevent local concentration within 1. In the figure, S is the suction pipe, 2
is water.

Since the present invention has the above-described configuration, the pump P is now driven by an electric motor (not shown) to supply water 4'l! through the suction pipe S! ! When the water 2 in T is sucked in and the water Z discharged from the discharge pipe is sent to each water pipe 3 in parallel via the connecting pipe 1 joint J, a nozzle installed at an appropriate position on the water pipe 3 is used. A jet jet ejected from n into the water tank T suppresses and atomizes the air taken in from the air port a at the upper end of the float F at the jet port d, and continuously creates a large amount of fine particles into the water tank 1. Eject as bubbles. Therefore, the presence of a large amount of fine air bubbles in the aquarium helps prevent water pollution, and the fish and shellfish being cultured can inhale enough fine air bubbles into their bodies to promote growth. In addition, the continuous jetting of water from the spout D d causes forced convection within the water bucket, and the water 2 and air are sufficiently and uniformly stirred. It is possible to sufficiently take in air from the float F into the water tank T due to the outflow, thereby preventing the possibility of insufficient suction in the water tank T. Moreover, it is possible to prevent the possibility of insufficient air flow in the water tank T, and also to reduce the electric motor required for agitation. Compared to conventional agitation equipment, which sets the pump above or below the water surface, the effort required to set up the prime mover can be significantly reduced, and since the rotating shaft is not inside the water tank, it is possible to locally grind the water. There is no accidental damage to the fish and shellfish caused by water pipes, and since the water pipe 3 is suspended at a substantially constant position below the water surface by the float F via the air pipe, the settings of the water pipe 3 and the air pipe are Not only can the position be easily confirmed, but the overall structure is not particularly complicated compared to conventional ones, so it is robust and can be constructed at low cost. be.

The above is an example when applied to a water pail T, but it is of course possible to apply it to a fish tank, aquaculture pond, etc. Any number of water pipes 3 can be selected. mo).
