Description

Jet aerator

This creation is about a jet aerator, especially a jet aerator that can increase the amount of dissolved oxygen in the water of the pond.

Aquaculture ponds usually raise high-density fish and shellfish, and a large number of cultures must metabolize a large amount of oxygen. If the dissolved oxygen in the water of the culture pond is lower than the consistent oxygen threshold, it will cause suffocation and death of the culture. There are: control the feeding amount to avoid excessive corruption of bait and affect water quality, limit livestock density to reduce oxygen consumption, regularly remove sludge at the bottom of the pool, replace new water and use aerator, etc., but face the sudden decrease of oxygen content In the case, only the use of an aerator can instantly and effectively improve the dissolved oxygen condition.

The conventional aerator is a water tank type aerator that increases the amount of dissolved oxygen in the pool water by rotating the blades to dial the water surface, but the range affected by the water pump is limited by the circumference of the blade and acts only on the blade. The surface of the pool water cannot fully increase the dissolved oxygen content of the pool water, nor can it agitate the bottom circulation of the pond.

Another conventional aerator is an aerated aerator that pressurizes air through a duct at the bottom of the immersion tank by an air compressor, and then discharges air bubbles from a plurality of air holes in the duct, and the air bubbles rise from the bottom of the pool. In the middle, part of the gas can be dissolved into the water and has the effect of disturbing the pool water. According to the installation range of the air duct and the power increase of the air compressor, the dissolved oxygen in the pool water can be widely increased, and the convective circulation of the bottom of the pool and the water surface can be improved. However, the energy consumption of the air compressor is huge, and the erection and maintenance of the air duct are not easy to implement.

Moreover, the proportion of air dissolved in water of the above aerator is low, and most of the bubbles are released into the atmosphere after floating on the surface, and once the aerator is stopped, the dissolved air content will fade with time, forcing the aerator to last for a long time.

The above and other objects, features and advantages of the present invention will become more apparent and obvious. The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings. In a first embodiment of the present invention, the jet aerator comprises a jet element 1, a flow guiding element 2 and an injecting element 3, the jet element 1 being hollow tubular for the flow guiding element 2 to extend. And fixed, the injection element 3 is disposed through the wall of the flow element 1 .

The spray element 1 has a spray tube 11 and a cover 12, and the cover 12 is coupled to one end of the spray tube 11. An acceleration space 13 is formed between the spray tube 11 and the cover 12, and the spray tube 11 The other end is provided with a first-class crossing 111. The accelerating space 13 has a conical space at one end of the flow passage opening 111. The accelerating space 13 has a minimum cross-sectional area connected to the flow passage opening 111. The guiding body 12 is provided with a guiding hole 121 at the center thereof. A first joint portion 122 is disposed on the inner edge of the flow hole 121.

One end of the flow guiding element 2 penetrates the guiding hole 121 and is received in the accelerating space 13 . The guiding element 2 has a guiding tube 21 and an adjusting member 22 , and the guiding tube 21 and the adjusting member 22 . The hollow guide tube is formed in a hollow tubular shape, and the guide tube 21 is movably fitted into the adjusting member 22; A second joint portion 221 is disposed on the outer edge of the adjusting member 22, and the second joint portion 221 is coupled to the first joint portion 122 of the cover body 12. The joint type is not limited. In this embodiment, The first joint portion 122 and the second joint portion 221 are combined by a thread.

Referring to Figures 2 and 6, one end of the draft tube 21 is connected to the atmosphere or a first pressurizing system P1 at one end, and the other end of the draft tube 21 is inserted into the adjusting member 22 by an outlet end 212. An accelerating space 13 extending into the interior of the spouting element 1 has a flow guiding gap 23 between the outlet end 212 and the flow port opening 111 of the spouting tube 11; wherein the inner edge of the guiding hole 121 and the adjusting member Preferably, the outer edge of the 22 is surrounded by a tapered space, and the combined direction end is smaller than the loose end, and the tapered space of the guide hole 121 is slightly smaller than the tapered space of the adjusting member 22, the adjusting member 22 can be tightly closed. The inner diameter of the adjusting member 22 is slightly narrowed to fasten the guide tube 21 and cannot be moved; when the adjusting member 22 is loosened from the guiding hole 121, the regulating member 22 is The inner diameter is slightly loose, so that the air guiding tube 21 can slide to the adjusting member 22 to adjust the relative position of the air guiding tube 21 and the flow path opening 111, and the cross-sectional size of the flow guiding gap 23 can be changed.

Referring to Figures 2 and 3, the injection element 3 has a first injection tube 31 which is hollow tubular. One end of the first injection tube 31 is connected to a second pressurization system P2, and the other end is connected. Passing through the wall of the nozzle 11 to communicate with the accelerating space 13, the first injection tube 31 preferably deviates from the central axis O of the jet tube 11, so that the second pressurizing system P2 pressurizes the fluid through the first injection. When the tube 31 enters the acceleration space 13, a forced vortex can be formed, and the fluid travels along the wall of the nozzle tube 11, and can uniformly diffuse into the axial direction to fill the acceleration space 13.

Referring to Figures 2, 4 and 5, the injection element 3 has a second injection tube 32, the second injection tube 32 is hollow tubular, and one end of the second injection tube 32 is connected to a third pressurization system P3. The other end penetrates the wall of the nozzle tube 11 and communicates with the acceleration space 13. The inside of the second injection tube 32 is provided with a check valve 321 to press the third pressurization system P3 through the second injection tube. 32 entering the acceleration space 13 , when the second injection pipe 32 is not connected to the third pressurization system P3 or the third pressurization system P3 stops working, the check valve 321 can prevent fluid from being added The speed space 13 flows back to the outside of the second injection pipe 32. The second injection tube 32 can input a medicament or a nutrient solution as needed, and cooperate with the pressurized fluid of the first injection tube 31 to form a forced vortex, and the medicament or nutrient solution and the pressurized fluid can be inside the acceleration space 13 . mixing.

Referring to FIG. 2, according to the structure of the first embodiment of the present invention, the accelerating space 13 inside the spouting element 1 can be filled with liquid by the first injection pipe 31, and the guiding tube 21 The inlet end 211 introduces air, and the outlet end 212 extends through the acceleration space 13. Due to the closing of the cover 12 and the flow guiding element 2 and the pressurization of the second pressurizing system P2, the liquid inside the accelerating space 13 can only be separated by the flow port 111 and the draft tube 21. The flow guiding gap 23 flows out. It is known from the mass continuity that the liquid flow rate per unit time is a constant value, that is, the product of the liquid flow velocity and the liquid passage cross-sectional area is constant and inversely proportional to each other, so the flow guiding gap 23 with respect to the minimum cross-sectional area is 23 There is a relatively large liquid flow rate, and Bernoulli's principle knows that the lowest flow rate of any horizontal flowing fluid has the highest flow rate, so the outlet end 212 of the draft tube 21 adjacent to the flow guiding gap 23 can be obtained. A reduced pressure generates a pressure difference from the atmospheric pressure of the inlet end 211, and the air is pushed through the draft tube 21 to mix with the liquid flowing out of the flow guiding gap 23, and the dissolved gas is ejected from the flow path opening 111. Jet flow.

The flow guiding gap 23 increases the pressure of the outlet end 212 relatively, and the pressure difference between the inlet end 211 and the outlet end 212 of the draft tube 21 is relatively reduced, resulting in a decrease in air flow rate through the draft tube 21, The flow rate of the liquid passing through the flow guiding gap 23 is constant, and the proportion of the air flowing through the flow path opening 111 is reduced.

Referring to FIG. 7, the first injection tube 31 of the injection element 3 penetrates the wall of the nozzle tube 11 at an oblique angle, so that when the fluid enters the acceleration space 13 through the first injection tube 31, the fluid has a The flow component to the runner port 111 and a flow component along the pipe wall of the jet pipe 11, so that an eddy current that advances axially toward the runner port 111 can be formed, and the dispersion is added. The impact of the pressurized fluid on the wall of the jet tube 11. When the fluid is naturally injected into the jet pipe 11 without being pressurized, the two flow components make the fluid lack sufficient kinetic energy to form a vortex along the pipe wall of the jet pipe 11, so the modification is suitable for the second pressurizing system P2 to accelerate the fluid at a high pressure. injection.

Referring to FIG. 8, which is a second embodiment of the present invention, the second embodiment of the present invention is substantially the same as the first embodiment described above, and the main difference is that the second embodiment of the present invention has a shunt tube 24; the flow guiding element 2 of the embodiment has an adjusting member 22, a flow guiding gap 23 and a shunt tube 24. The adjusting member 22 and the guiding gap 23 have substantially the same structure as the first embodiment. For example, only the shunt tube 24 will be described in detail below. The shunt tube 24 is provided with an inlet end 241, a closed end 242 and a plurality of through holes 243. The inlet end 241 is connected to a first pressurizing system P1, and the other end of the shunt tube 24 forms the closed end 242. The shunt tube The adjusting portion 22 is disposed on the adjusting member 22, and the closed end 242 extends through the accelerating space 13. The closed end 242 forms a flow guiding gap 23 with the flow port opening 111 of the spout tube 11. The plurality of through holes are formed. A 243 ring is disposed on the wall of the shunt tube 24 to communicate the interior of the shunt tube 24 with the accelerating space 13.

When the liquid is pressurized by the first pressurizing system P1, the liquid can enter the accelerating space 13 via the plurality of through holes 243; the second pressurizing system P2 pressurizes the gas into the accelerating space through the first injection pipe 31. 13; the third pressurizing system P3 pressurizing agent or nutrient solution enters the accelerating space 13 through the second injecting pipe 32, so that the liquid is evenly dispersed and the air and the medicament or the nutrient solution are sufficiently mixed, and then discharged from the channel port 111. Contains a gas, functional jet.

In summary, the jet aerator has created a high-speed and low-pressure water flow by compressing the flow space to form a pressure difference, and the intake air and the water flow are mixed to form a water flow containing a large number of tiny bubbles, so that the bubbles diffuse in the direction of the water flow. Dissolve and increase the proportion and range of air dissolved water in the culture pond. Moreover, the medicament or the nutrient solution can be introduced into the jet pipe through the injection pipe with the check valve, and can be widely dispersed in the pool water during the jet flow process, thereby saving work time and manpower. In addition, the direction, position and flow rate of the jet can be adjusted, so that the aeration operation can simultaneously generate a circulation function to optimize the water quality of the culture, and the underwater rotation mechanism can be eliminated, thereby avoiding damage to the culture.
