Oxygen increasing machine for aquiculture

Abstract

An aquaculture automatic aerator with simple structure, stable performance, low cost, low process and low power consumption is suitable for aeration of aquaculture water body of non-freezing water surface. The automatic aerator mainly comprises a motor, a motor case, a special nozzle, a screen stencil, a bracket and a float body. The motor is arranged on the water surface by the float body and the bracket. The axile bush of the special nozzle is directly connected with motor shaft. The special nozzle comprises a motor shaft bush, a centrifugal impeller part, a main pipe part and a propeller part; the propeller is connected with one end of the main pipe; the other end of the main pipe is connected with one cover blade of the centrifugal impeller; the other cover blade of the centrifugal impeller is connected with the motor shaft bush. The centrifugal impeller part comprises two cover blades and centrifugal blades; the cover blade connected with the motor shaft bush forms a cone shape and the cover blade connected with one end of the main pipe forms a funnel shape; the centrifugal blade is held between the two cover blades.

Description

Technical field [0001] The utility model relates to an aeration equipment for aquaculture, which is suitable for implementing aeration for aquaculture water bodies on non-frozen water surfaces. Background technique [0002] At present, the aeration principle of the widely used aquaculture aeration machine is to sprinkle the water body on the water surface to make the water fully contact with the air, so as to increase the oxygen content of the water body. (1) It can be divided into two categories from the working mode of aeration: the first category, the water spray aerator that sprays water in the form of a fountain; the second category, the speed of the motor shaft is decelerated by the gearbox, and then The shaft in the gearbox drives the impeller to stir the water surface, causing the water surface to oscillate and produce splashes, increasing the contact surface between water and air to increase the oxygen content of the water body. Oscillating aerators: can be divided ...

AI Technical Summary

Problems solved by technology

The oxygenation effect is not as good as that of the water spray aerator. The reason: it is determined by the working method of the oscillating aerator, and the impeller of the oscillating aerator fails to completely sprinkle and disperse the water body on the water surface, making the water body Full contact with the air; the power consumption is greater than that of the water spray aerator. The reason is that the impeller of the oscillating aerator is too large, so the resistance of the water body is also large. The actual use also shows that the power consumption of the oscillating aerator is greater than that of the spray aerator. Water-type aerator; the manufacturing process requirements are equivalent to those of the water-spray aerator. The reason is that the oscillating aerator has a gearbox, and the gearbox is an important device for mechanical energy transmission. Therefore, the manufacturing process requirements for the gearbox are relatively high; the service life is longer than The reason for the water spray aerator is: the oscillating aerator is an air-cooled aerator, the motor is placed on the water surface by the floating body and the bracket, and the motor uses air cooling to dissipate heat. This design keeps the motor away from high temperature and humidity. Hidden danger, this is also the reason why the performance stability of the oscillating aerator is greater than that of the water spray aerator
