Description

Aquaculture container with air pressure layer and pressure relief port

Technical Field

The invention relates to an aquaculture container, in particular to an aquaculture container used in the live transportation or long-time aquaculture process of aquatic products.

Background

At present, the known aquatic organism culture container generally refers to a fishpond, a fishpond or a fish tank and the like, an oxygen increasing system of the container stirs water by an air pump or a water pump and the like, namely, oxygen increasing equipment is externally arranged, and the air flow direction in the water is not taken into consideration when the aquaculture container is built.

The invention is the biggest difference with the past aquatic organism culture container that the container is provided with a special structure in addition to water storage, and under the condition that an external air pump is added to pressurize an air pressure layer after the regulated minimum water level is reached, the air pressure borne by the water body in the container is divided into a high pressure area and a low pressure area, so that the gas can be easily dissolved into the water from the high pressure area, and the dissolved gas in the water can be discharged from the low pressure area, and the adjustment of the dissolved gas in the water through the design is simple and controllable.

Disclosure of Invention

Firstly, a pressurizing cover plate is arranged at the top of a container, but the pressurizing cover plate does not seal the top of the whole container, but leaves a pressure relief opening, a circle of water storage coaming plate is arranged upwards along the pressure relief opening, a circle of air pressure layer sealing plate is arranged downwards along the pressure relief opening, the length of the air pressure layer sealing plate can not reach the bottom of the container, then water is injected into the container, the height of the water must exceed the lowest point of the air pressure layer sealing plate, at the moment, water is continuously added, the water can not reach the bottom of the pressurizing cover plate corresponding to the air pressure layer, because the bubbles can not be discharged, the water can lift the water level in the pressure relief opening, an air pump is started, more bubbles are injected into the air pressure layer through an air conduit, at the moment, the air pressure layer is increased, the water is pressed downwards by the bubbles, the water can only pass through the lowest point of the air pressure layer sealing plate and overflows from the water storage opening, and the water level in the air pressure layer sealing plate and the coaming plate corresponding to the pressure relief opening is further lifted, the air pressure of the air pressure layer is determined by the water level height in the sealing plate of the air pressure layer and the water storage enclosing plate corresponding to the pressure relief opening, because the water body corresponding to the pressure relief opening is only one atmospheric pressure, and the air pressure layer is the pressure generated by the water level plus one atmospheric pressure, the air pressure borne by the water body corresponding to the air pressure layer and the water body corresponding to the pressure relief opening is divided into high and low, the water in the container is communicated with each other, but the external air pressure borne by different areas of the water body is different, the air pump continues to send the air bubbles to the air pressure layer, part of the air bubbles are extruded below the sealing plate of the air pressure layer, so the part of the air bubbles pass through the lowest point of the sealing plate of the air pressure layer, and under the buoyancy effect generated by the air bubbles, the air bubbles overflow the container at the highest point of the water stored in the water storage enclosing plate through the pressure relief opening, and disturb the water in the pressure relief opening, so that the air pressure borne by the part of the water is reduced, the saturation value is reduced according to the Henry principle, so that dissolved gas is separated out, after the bubble disturbance is stopped, the saturation value is increased, and the gas in the high-pressure area is relatively high in dissolved concentration, so that the dissolved gas in the water automatically diffuses to the low-pressure area and sucks the gas in the pressure layer, and the process is repeated, so that the gas in the pressure layer is dissolved in the whole water.

The air pressure layer is a closed air layer, air bubbles are pumped in by the air pump, and the air is dissolved into water by exchange, so that the air required to be dissolved into the water is added into the air pressure layer in advance by the air pump, and the air required by the aquaculture industry culture process, such as pure oxygen, ozone and the like, is proportionally pumped into the air pressure layer.

The lowest point of the sealing plate of the pneumatic layer does not mean the lowest point of the plate falling, but means the horizontal position of the point through which water and air bubbles can pass when passing from the pneumatic layer to the pressure relief opening.

After the air pressure layer is continuously added with air bubbles, the air bubbles cross the lowest point of the sealing plate of the air pressure layer and then pass through the water layer in the pressure relief port to be discharged out of the container, so that the air pressure of the water body in the pressure relief port is reduced, the air pressure is reduced according to the Henry principle, the saturation value is reduced, and the gas dissolved in the water body is released due to the reduction of the saturation value.

When bubbles are discharged from the pressure relief opening, water in the low-pressure area is disturbed, so that the saturation value of the water is reduced, and after dissolved gas in the water is released, the gas in the water in the high-pressure area is diffused to the water in the low-pressure area, so that the gas dissolution amount of the water in the high-pressure area is reduced, the pressure of the air pressure layer is not changed, and the gas in the air pressure layer is absorbed into the water.

The aquaculture container is not a closed container, aquatic organisms can enter and exit through the pressure relief opening, water can enter or overflow through the passage, and even under the condition of opening, part of water in the container is also raised by air pressure.

The invention has the advantages that when the aquaculture container is established, the water in the container is structurally divided into a high-pressure area and a low-pressure area, the high-pressure area can easily dissolve the added gas into the water, and the low-pressure area can easily discharge the gas in the water.
