Technical Field

[0001] The invention relates to the technical field of rotifer cultivation, in particular to a rotifer nutrition intensification cultivation device. Background Art

[0002] In the process of silver pomfret breeding, rotifers, as high-quality bait and food source, have many advantages: individual rotifers are usually around 100-500 microns, which matches the size of the mouth of newly hatched silver pomfret larvae, and the larvae can easily eat them, reducing the difficulty of feeding and energy waste caused by too large or too small food, and improving the feeding efficiency and survival rate of the larvae; rotifers are rich in nutrients such as protein, unsaturated fatty acids, vitamins and minerals, among which the protein content is generally around 50%-70%, and the content of unsaturated fatty acids such as DHA and EPA is also high. These nutrients are essential for the growth, development and health of silver pomfret larvae, and can meet their energy needs and physiological metabolic needs for rapid growth. Rotifers are a common microscopic aquatic organism. Due to their advantages of fast growth, strong fertility and easy cultivation, rotifers are widely used in silver pomfret breeding and other fish.

[0003] Existing rotifer culture devices are generally culture pools, which place rotifers and algae together for reproduction and growth, and the algae can provide the oxygen and food required for the growth of rotifers. For example, the prior art publication number is CN111248139A, which is a high-density rotifer culture device and method. The invention includes a rotifer culture device, which includes a culture tank, a microalgae culture barrel, and a central control system.

[0004] However, the above-mentioned prior art still has the following problems when used: traditional rotifer culture devices directly place rotifers and algae in a culture pool for natural reproduction and growth, and only rely on algae as food for rotifers. The nutritional content of rotifers is low. When cultivating silver pomfret fry, the nutritional content provided by rotifers is low, which will cause the silver pomfret fry to grow slowly and have a low survival rate. Based on this, the present invention provides a rotifer nutrition enhancement culture device. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Refer to the instruction manual Figure 1-8 The present invention provides a rotifer nutrition enhancement culture device, comprising a culture pool 1 for culturing rotifers and algae, wherein a culture component 2 is installed on the culture pool 1, wherein the culture component 2 comprises a top plate 21 located above the culture pool 1, wherein the top plate 21 is connected to the culture pool 1 via a rotating component 3, wherein a fluorescent lamp 22 and an adjustment mechanism 23 are detachably connected to the bottom end of the top plate 21, wherein the adjustment mechanism 23 is located on one side of the fluorescent lamp 22, wherein a nutrition enhancement component 4 is detachably connected to the bottom end of the top plate 21 away from the adjustment mechanism 23, wherein the nutrition enhancement component 4 comprises a material bottle 41 storing yeast, wherein the material bottle 41 is located on the side of the adjustment mechanism 23 away from the fluorescent lamp 22, and is used for automatically injecting yeast to enhance the nutrition of the rotifer; In this embodiment, the fluorescent lamp 22 can be selected from Philips MASTER T814W. The LED light source of the fluorescent lamp has the advantages of high light efficiency, energy saving, and long life. Its 14W power can replace the traditional T836W fluorescent lamp, provide stable lighting in rotifer culture, and have a high color rendering index, which can truly restore the growth environment of rotifers, and will not generate excessive heat, reducing the interference of temperature changes on the growth of rotifers; Next, a support plate 42 is sleeved on the outer wall of the material bottle 41. The support plate 42 and the material bottle 41 are both located on the side of the adjustment mechanism 23 away from the fluorescent lamp 22, and the top end of the support plate 42 is connected to the bottom end of the top plate 21. The end of the material bottle 41 close to the adjustment mechanism 23 is connected to the feed pipe 43 through a control valve. A liquid outlet pipe 8 is installed on the side of the culture pool 1 away from the servo motor 32, and the liquid outlet pipe 8 is connected to the inside of the culture pool 1. A plurality of supporting legs 9 are fixedly provided at the bottom end of the culture pool 1 to improve the stability of the culture pool 1.

[0019] In actual use, rotifers and algae reproduce and grow in the culture solution in the culture pool 1. Algae are rich in nutrients such as protein, carbohydrates, fats, vitamins and minerals. These nutrients can meet the needs of rotifer growth and reproduction. For example, chlorella is poured into the culture pool 1. Chlorella is rich in protein, with a content of up to 50%-60%. Its amino acid composition is also relatively reasonable, which can provide high-quality protein nutrition for rotifers, thereby enhancing the nutrition of rotifers. In addition, a fluorescent lamp 22 is used to rotate around the culture pool 1 to provide sufficient light for the rotifer and Chlorella, so that the Chlorella can grow better. The Chlorella can also provide oxygen during photosynthesis to promote better reproduction of the rotifer. In addition, yeast is intermittently added to the culture pool 1 using a feed bottle 41. Yeast is rich in protein, and its protein content is usually around 40%-60%, and its amino acid composition is relatively balanced. These proteins can provide the rotifer with the nitrogen source required for growth and reproduction, thereby further promoting the growth of the rotifer and improving the nutrition of the rotifer, so that the rotifer can provide sufficient nutrition for the silver pomfret seedlings.

[0020] Refer to the instruction manual Figure 1-6 The rotating assembly 3 includes an outer gear ring 31, which is movably sleeved on the top of the outer wall of the culture tank 1, and the support plate 42 is detachably fixed to the top of the outer gear ring 31. A detachable servo motor 32 is fixedly arranged on the outer wall of one side of the culture tank 1. The servo motor 32 is a motor that can accurately control the position, speed and torque. The servo motor model ECMA-C10602ES can be selected. A gear 33 meshing with the outer gear ring 31 is fixedly sleeved on the output shaft of the servo motor 32; The regulating mechanism 23 includes a vertical rod 231, the top end of the vertical rod 231 passes through the top end of the top plate 21, a mounting groove 232 is provided in the vertical rod 231, an air pipe 233 is fixed in the mounting groove 232, and at least two aeration heads 234 are connected to the air pipe 233, and one end of each aeration head 234 passes through the outer wall of the vertical rod 231; A detachable shield 7 is installed at the top of the top plate 21, and an air pump 235 detachably connected to the top plate 21 is arranged inside the shield 7. The air pump 235 can be selected from XGB-5500W / 5.5KW, with a power of 5.5KW, which is suitable for oxygenation, aeration and other occasions, and has the advantages of high efficiency, dust prevention, stable performance, low noise, etc. One end of the air pipe 233 is connected to the air outlet of the air pump 235, and the air pump 235 transports gas into the air pipe 233, and the gas is ejected from the aeration head 234 to provide oxygen for rotifers and algae; At least one pH detector 236 is fixedly embedded in the outer wall of the vertical rod 231. Specifically, the pH detector 236 is of model HI253A, and its pH resolution can reach up to 0.001pH, with an accuracy of ±0.01pH; ±0.002pHorp. It has excellent GLP management function and data storage function, and is therefore suitable for detecting the pH value in the culture medium. At least one heating plate 237 is fixedly installed on the outer wall of the vertical rod 231. The heating plate 237 is of model SBWK-FB0.5 / 220 explosion-proof and waterproof electric heating plate, a fully cast aluminum alloy heat dissipation heater with low design power load and large heat dissipation area. It has a dual temperature protection device and is suitable for heating in an environment with water and high humidity. Multiple heating plates 237, multiple pH detectors 236 and multiple aeration heads 234 are spaced apart on the vertical rod 231.

[0021] The gear 33 connected thereto is driven to rotate by the servo motor 32, and the rotation of the gear 33 drives the outer gear ring 31 to rotate on the outer wall of the culture tank 1, so that the fluorescent lamp 22 can illuminate the rotifers and Chlorella in the culture tank 1 in all directions. At the same time, the multiple heating plates 237 on the vertical rod 231 stir the culture solution, so that the rotifers and algae are evenly distributed in the culture tank 1, avoiding the rotifers and algae from gathering in local areas and causing uneven distribution of light and nutrients. In addition, the temperature of the culture solution can be adjusted by the heating plate 237, so that the rotifers and Chlorella grow in the culture solution at a suitable temperature. The air pump 235 is used to transport air into the air pipe 233. When the air is ejected from the aeration head 234, the culture solution can flow, which can not only move the rotifers and Chlorella, but also provide some oxygen. At the same time, the pH detector 236 on the vertical rod 231 detects the pH value of the culture solution in real time, so that the staff can adjust the pH value in the culture solution.

[0022] Refer to the instruction manual Figure 1-5 At least one elastic rod 5 is fixedly provided at the top of the culture pool 1, and a knocking ball 6 is fixedly provided at the top of each elastic rod 5. The feed pipe 43 and the elastic rod 5 are both made of nitrile rubber, and the knocking ball 6 is made of stainless steel.

[0023] Whenever the feed tube 43 on the feed bottle 41 contacts the elastic rod 5 on the culture tank 1, both are made of nitrile rubber and therefore have a certain elasticity. The elastic rod 5 and the feed tube 43 will be deformed by squeezing each other. When the feed tube 43 is removed from the elastic rod 5 and the two restore their shapes, the stainless steel knocking ball 6 on the elastic rod 5 will quickly knock on the feed tube 43, causing the feed tube 43 to vibrate and shake out the residual yeast. When the feed tube 43 restores its shape, it will vibrate, thereby effectively avoiding yeast residue.

[0024] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
