Description

[Detailed explanation of the idea] 《Industrial application field》 This invention relates to an aquarium for breeding fish and shellfish.

《Prior Art》 Conventional aquariums had flat bottoms, and the feces that had accumulated on the bottom had to be vacuumed up from time to time with a pump.

《Problem that the invention aims to solve》 However, this kind of cleaning requires a lot of effort.

The purpose of this invention is to provide an aquarium that can automatically drain sediment.

<Means for Solving the Problems> The biological aquarium of this invention includes: an aquarium with an inclined bottom so that sediment collects at the bottom of the valley; a water supply pipe that continuously supplies water to the aquarium; It consists of a siphon pipe led from the bottom of the tank, and a ventilation pipe led into the tank from the top of the siphon pipe.

Preferably, a plurality of discharge holes are provided at intervals along the bottom of the water tank, and the interior of the water tank and the siphon pipe are communicated through these holes.

<<Operation>> When water is continuously supplied to the aquarium, the liquid level in the aquarium gradually rises, and when it reaches the highest point of the siphon tube, the water in the aquarium is discharged from the bottom of the valley to the outside through the siphon tube. At this time, the sediment that has accumulated at the bottom of the valley is also caught up in the water flow and discharged to the outside.

When the liquid level in the tank becomes lower than the tip of the ventilation tube, air is sucked into the siphon tube from the tip of the ventilation tube.
The siphon phenomenon stops. Then, the liquid level in the tank rises again.

Repeat this process.

Note that if a plurality of holes are provided at intervals along the valley bottom of the water tank, and the inside of the water tank and the siphon pipe communicate with each other through these holes, water will be uniformly drawn into the siphon pipe from the valley bottom. Therefore, it is difficult for deposits to remain.

<<Example>> In the drawings, reference numeral 1 is a water tank, and its bottom 1
A is made in the shape of a V, and the excrement of the fish and shellfish raised inside is designed to settle on the valley floor 2.

A discharge pipe 3 passes through the valley bottom 2, and the discharge pipe has a plurality of discharge holes 4 spaced apart from each other. A siphon tube 5 is led from one end of the discharge tube 4. Top part 5 of siphon tube 5
A is a position lower than the upper edge of the water tank 1, from which a ventilation pipe 6 is guided into the water tank, and its tip is located at a position lower than the highest part 5a of the siphon pipe.

Reference numeral 7 is a water supply pipe, from which water is continuously supplied to the water tank 1.

Water is continuously supplied and the liquid level in the water tank 1 gradually rises, and when the liquid level reaches level A, which is the same height as the highest part 5a of the siphon tube, the water in the water tank 1 reaches the highest point in the siphon tube. The air flows out beyond the portion 5a, and due to this flow, the air inside the vent pipe 6 is sucked toward the siphon pipe and gradually discharged together with the water. Eventually, when the air inside the vent pipe 6 disappears and the vent pipe 6 becomes filled with water, a siphon phenomenon occurs, and the water in the tank 1 flows out forcefully through the siphon pipe 5. At this time,
Sediment 8 such as feces that has settled on the valley floor 2 is sucked out from the discharge hole 4 together with water. It should be noted that since the plurality of discharge holes 4 are spaced apart from each other along the valley floor 2, water is evenly sucked into the siphon pipe 5 from the valley floor 1, and the sediment 8 is evenly discharged. Should.

When the liquid level in the water tank 1 falls and reaches level B, the tip of the vent pipe 6 comes out of the water, air is sucked into the siphon pipe 1, and the siphon phenomenon stops. Therefore, the discharge from the siphon tube 1 is stopped, and the liquid level in the water tank 1 starts to rise again.

In this breeding tank, the above operations are repeated.

<<Effects>> The aquarium according to claim 1 continuously supplies water to the aquarium with an inclined bottom, and when the tank becomes full, the water overflows with sediment from the siphon pipe led from the bottom of the aquarium to the outside, causing the liquid to flow out. When the surface falls to a certain level,
Air is sucked in through the ventilation pipe, the siphon phenomenon stops, and the liquid level rises again, which is a repeated action.The inside of the aquarium can be kept clean at all times without the need for human intervention, and there are no moving parts and the structure is extremely simple. Simple and reliable.

According to the breeding aquarium of claim 2, since the plurality of discharge holes are distributed at intervals along the valley bottom,
Can be discharged without leaving any sediment.
