Description

Aeration and oxygenation device

This creation is related to an aeration and aeration device, especially an aeration and aeration device that can reliably inhale and mix air into the water to increase the oxygen content in the water.

Aquatic products all live on water, so the quality of the water in the breeding environment is closely related to the growth and breeding of the breeding organisms and their resistance to diseases. Among them, when the cultured fish and shrimp are hypoxic, they will have floating heads, irritability and shortness of breath, and even slow the growth rate and cause the death of the cultured fish and shrimp.

A common way to increase the amount of dissolved oxygen in the breeding environment is to set up a waterwheel on the breeding pond. The waterwheel is equipped with a frame on a float, the frame is equipped with a motor, the output shaft of the motor is connected to a transmission rod, and the transmission rod is sleeved There is a water-lifting wheel; according to this, when the motor starts to run, it can drive the water-lifting wheel, so that the blades on the water-lifting wheel flap and move the water surface to produce splashes and turbulence, hoping to achieve the effect of increasing the amount of dissolved oxygen in the pool.

Because the existing waterwheel uses blades to flap and move the water surface to introduce air into the pool water, it can only create disturbance and aeration effects on the surface waters of the breeding pool, but it is difficult to achieve improved solubility for deeper pool water. The effect of oxygen cannot solve the problem of insufficient oxygen supply in the lower waters. In particular, the bottom of the water body contains a large number of dead algae, zooplankton carcasses, residual bait, feces, etc., and its oxidative decomposition requires a large amount of oxygen, which accounts for about 40% of the total oxygen consumption of the aquaculture water. Therefore, increasing the dissolved oxygen in the bottom of the aquaculture pond has Its necessity.

Therefore, an industry has developed a submersible pump as a device to increase the oxygen content at the bottom of the pool, which is mainly driven by a motor to drive the upper and lower impellers to rotate, and the suction force is generated in the space corresponding to the lower impeller to inhale the water. , And then discharge a strong water flow from the drainage port. At the same time, because the space corresponding to the upper impeller is connected to the outside, air is introduced, and the air is sucked into the mixing flow channel, mixed with the water flow, and sprayed out from the drainage port to achieve exposure. The purpose of the gas, such as Taiwan Announcement No. M571380 "Aerator" and Taiwan Announcement No. I674144 "Multi-angle rotating liquid-gas mixing device" belong to the design of this type of structure. However, because of the above-mentioned No. M571380 and No. I674144 In the patented aeration device, because the inlet flow path introduces air into the water flow, the position is designed before the compression section of the mixing flow path, and the pressure of the lower impeller inhales the water body, which makes it difficult to draw air into the gas-liquid mixing flow path. On the contrary, the water flows backward from the air inlet into the space where the upper impeller is arranged, which hinders the introduction of air into the mixing channel through the air inlet and affects the effect of gas-liquid mixing.

Today, the creator of the present invention has corrected and improved the above-mentioned traditional oxygen supply water tankers and the use of submersible pumps as devices to increase the oxygen content at the bottom of the pool.
