[0002] In recent years, with the rapid development of aquaculture industrialization, microalgae, as a special type of organism with fast growth, easy cultivation and strong survival ability, has played an increasingly important role in aquaculture. Microalgae are not only rich in a variety of nutrients that are essential for the growth of aquatic organisms, but also because of their small size, they are easily ingested by aquatic organism seedlings, which has a significant effect on enhancing the immunity of shellfish seedlings and improving their survival rate. Therefore, microalgae are widely used as live bait in aquaculture.

[0003] However, the traditional artificial feeding method has the following problems: 1. The feed is not evenly fed, resulting in low feed utilization and high residual rate, which further leads to uneven growth of shellfish fry and easily causes nutrient enrichment in the water, which is not conducive to the growth of shellfish fry. 2. It is not compatible with the factory aquaculture model, with high labor intensity and low feeding efficiency. Utility Model Content

[0031] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0032] like Figure 1 An aerated two-liquid mixing feeding device includes a mixing barrel 2 for placing algae liquid and water, and also includes a mixing device for driving the algae liquid and water to mix.

[0033] like Figure 4 The mixing barrel 2 is mounted on a support base 3, and a support leg 4 is connected to the bottom of the support base 3. A placement plate 5 is also provided below the support base 3, and the placement plate 5 is fixed on the support leg 4.

[0034] The upper end of the mixing barrel 2 is provided with an algae liquid inlet 1 for injecting algae liquid with a certain concentration.

[0035] like Figure 3 A plurality of support blocks 9 are also installed at the upper end of the inner wall of the mixing barrel 2, and an annular water pipe 7 is placed on the support block 9. Water outlet holes are evenly arranged at the bottom of the annular water pipe 7, and the annular water pipe 7 is also connected to a water pipe access port 8 located outside the mixing barrel 2. The water pipe access port 8 is used to connect to an external waterway, and water can be evenly and fully sprayed into the mixing barrel 2 along the annular water pipe 7, which can assist in mixing on the one hand, and can also clean the algae attached to the barrel wall on the other hand.

[0036] In this embodiment, the mixing device is an aeration device 6 , and the aeration device 6 includes a plurality of aeration heads 6 - 4 arranged inside the mixing barrel 2 .

[0037] like Figure 2 The aeration device 6 also includes a blower 6-1, an air valve 6-2 and a gas pipeline 6-3.

[0038] The blower 6-1 is installed on the placement plate 5. The air outlet of the blower 6-1 is connected to the gas pipeline 6-3 through the air valve 6-2. Multiple branches of the gas pipeline 6-3 extend from the bottom into the mixing barrel 2, and the aeration head 6-4 is installed at the end of each branch.

[0039] Furthermore, the aeration head 6 - 4 is spherical, and a plurality of air outlet holes are provided on the surface of the aeration head 6 - 4 , so that the high-concentration algae liquid and water in the mixing barrel 2 are evenly mixed by aeration.

[0040] In other optional embodiments, the mixing device may be a blade stirring device or other device that can perform a mixing function.

[0041] like Figure 1 The water outlet of the mixing barrel 2 is connected to a delivery pipeline, a water pump 11 is provided on the delivery pipeline, and a bait-casting nozzle 14 is provided at the end of the delivery pipeline. The water pump 11 is connected to a timing controller, and the timing controller can control the water pump 11 to start / stop.

[0042] Furthermore, the delivery pipeline includes a main pipeline 12 connected to the water outlet end of the mixing barrel 2 and a plurality of branch pipelines 13 connected to the main pipeline 12 .

[0043] The water pump 11 is arranged on the main pipeline 12 , and the bait-casting nozzle 14 is arranged at the end of the branch pipeline 13 .

[0044] The feeding nozzle 14 is provided with a hemispherical surface, and a plurality of injection holes are provided on the hemispherical surface, so that the feed is sprayed out in multiple directions and evenly sprayed into the breeding pond, thereby avoiding the phenomenon of uneven feeding and high concentration of feed.

[0045] Preferably, a screen 10 is provided at the water outlet of the mixing barrel 2. The screen 10 is disc-shaped and has a plurality of mesh holes, which are the same size as the injection holes of the bait-casting nozzle 14. The screen 10 can prevent excessive impurities from flowing into the conveying pipeline and causing the bait-casting nozzle 14 to be blocked.

[0046] During operation, algae liquid reaching a certain concentration flows into the mixing barrel 2 from the algae liquid water inlet 1, and at the same time, water flows into the annular water pipe 7 through the water pipe inlet 8, and then flows into the mixing barrel 2 along the barrel wall or is directly sprayed into the mixing barrel 2. The concentration of the quantitative water and algae liquid after mixing should reach the feeding standard. Before feeding, the blower 6-1 supplies air, and the gas is sprayed through the air valve 6-2, the gas pipeline 6-3 and the aeration head 6-4, so that the high-concentration algae liquid and water are evenly mixed, and then the water pump 11 evenly delivers the mixed liquid into the culture pond along the conveying pipeline and the feeding nozzle 14. The timing controller can control the starting frequency and duration of the water pump 11, so as to achieve the purpose of timing and quantitative feeding.

[0047] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
