Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hydroponic cultivation apparatus that simultaneously performs oxygen enrichment, liquid flow, and vertical movement of the liquid level by supplying air to the liquid in the aquarium.

Conventional aquarium liquid oxygen enrichment and flow equipment are used in biological breeding tanks and the like. Furthermore, equipment whose liquid level (water level) fluctuates is used in hydroponic cultivation of plants and the like. As a method of oxygen enrichment and liquid flow,
One method is to supply air to the bottom of the aquarium with an air supply pump and flow the liquid with a floating air flow to the water surface (liquid flow) to enrich oxygen. There is a method of enriching oxygen with an enrichment device. The vertical movement of the liquid level is caused by a liquid pump.

However, this method of using an air pump requires a large amount of air, and the efficiency decreases as the shallow water area increases. Furthermore, the method of using a liquid pump is not effective in enriching the liquid with oxygen, although it consumes a large amount of power.

In view of the above-mentioned drawbacks of the conventional art, the present invention temporarily stores the air from the air piping in a storage area divided by partitions, and releases the accumulated air to a certain extent into the liquid at once, thereby improving oxygen enrichment and liquid flow. The device moves the liquid level up and down, and will be explained in detail below based on the drawings.

A partition 2 is arranged in a water tank used for hydroponic cultivation to form an air reservoir 3. An air pipe 1 connected to an air pump is arranged at the bottom of this partition 2.
The liquid in the upper part of the partition 2 and the liquid in the reservoir are connected through one or more communication pipes 4. By attaching a valve to this, you can also determine the direction of water flow. Alternatively, the lateral surface may be partitioned without providing the communication pipe 4, and the lower portion may be opened.

One end of the U-shaped air discharge pipe 5 is opened to the upper part of the air reservoir 3 divided by the partition 2, and the other end passes through the partition 2 and faces the upper liquid. The lower part of the U-shaped air discharge pipe 5 is located slightly higher than the lower open end of the communication pipe 4.

Next, the effect will be explained.

The air discharged from the air pump through the air piping 1 into the aquarium enriches the oxygen in the liquid while discharging the liquid in the air reservoir 3,
It accumulates inside. At this time, the water level in the U-shaped air discharge pipe 5 falls together with the water level in the air reservoir 3.

When air continues to accumulate in the air storage area 3 and reaches the bottom of the U-shaped air release pipe 5, the air passes through the air release pipe 5 and is released into the liquid at the top of the partition 2 while enriching it with oxygen. Ru. As the air is released, the water level in the air reservoir 3 rises, and the air is released until the water level reaches the air release pipe 5+inlet. When this water surface reaches the inlet of the air discharge pipe 5, the discharge of air stops.

Then, the air from the air inlet 4 accumulates in the air reservoir 3 again.

In this way, the liquid level in the water tank rises and falls as the air in the air reservoir 3 is stored and released, and the liquid in the water tank flows each time.

In short, the present invention arranges a partition 2 for storing air in an aquarium, attaches an air pipe 1 to the lower part of the partition 2, and
One side of the U-shaped air discharge pipe 5 is open to the upper part of the hangout area divided by the partition 2, and the other side is exposed to the liquid above the partition 2, so that the liquid bath required for the hydroponic cultivation device is reduced. It is possible to enrich the oxygen content, fluidize the liquid, and move the liquid level up and down in a simple and inexpensive manner, which has great advantages.
