Description

Technical Field

[0001] This utility model relates to the field of Artemia salina egg collection technology, specifically to a collection and separation device for Artemia salina eggs. Background Technology

[0002] Artemia (brine shrimp) has become an important resource in aquaculture and scientific research due to its unique biological characteristics. Its dormant eggs are resistant to drying and can be stored for a long time. They hatch within 24 hours of being unsealed, providing high-protein, active feed for fish and shrimp larvae, with nutritional value surpassing that of artificial feed. Adults contain over 60% protein and unsaturated fatty acids, significantly improving larval survival rates. Its salt and alkali tolerance eliminates resource competition during cultivation, and eggshell separation technology enables industrial-scale collection.

[0003] Traditional methods of collecting Artemia salina eggs involve manual rinsing, which floats the eggshells in water to achieve a separation purity of 80%. However, this method suffers from low efficiency, high water consumption, and a high rate of egg breakage. Therefore, existing centrifuges with eggshell separation technology are used to improve the purity and efficiency of eggshell separation. However, during operation, they cannot effectively collect eggshells and soil, leading to clogging in subsequent operations. Utility Model Content

[0004] The purpose of this invention is to provide a collection and separation device for Artemia salina eggs, in order to solve the problem that existing centrifugal devices for egg shell separation technology cannot effectively collect egg shells and soil, leading to easy blockage during subsequent operations.

[0025] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0026] See Figures 1 to 4This utility model provides a device for collecting and separating Artemia salina eggs, including an incubation box 1. The top of the incubation box 1 is provided with a separation component. One end of the separation component is hinged to the side of the top surface of the incubation box 1, and a drive component 2 extends from the side of the top surface of the incubation box 1. The drive component 2 extends into a first fixing block 3 provided on the side of the top surface of the incubation box 1. The first fixing block 3 is provided with a drive motor. The output end of the drive motor extends into the first fixing block 3 and engages with the drive component 2. A cultivation box 4 is connected to the side of the incubation box 1. A light source component is provided on the top of the cultivation box 4. The light-emitting end of the light source component extends into the cultivation box 4. A heating film is attached to the inner side wall of the incubation box 1 and connected to an external power source. A bottom tube 23 is provided at the bottom and connected to an external oxygen generator. A spare light source is connected to the light source component.

[0027] It should be noted that during the day, natural light is used to illuminate the top of the incubation box, while an external oxygen generator is activated to supply oxygen to the bottom pipe 23 for aeration, and an external power supply is activated to heat the heating membrane, maintaining the water temperature inside the incubation box 1 at 28℃. At night, a backup light source 24 is used to provide light, while an external oxygen generator is activated to supply oxygen to the bottom pipe 23 for aeration, and an external power supply is activated to heat the heating membrane, maintaining the water temperature inside the incubation box 1 at 28℃ to facilitate the hatching of Artemia eggs.

[0028] In addition, a one-way valve is installed at the top of the bottom pipe 23 to prevent water from flowing back into the incubator 1 when oxygen is output, thus affecting the operation of the external oxygen generator.

[0029] In this embodiment, water is filled into the incubation box 1, and the water flow can circulate into the cultivation box 4. After the water level reaches the top surface of the separation component, the pre-hatched brine shrimp eggs are placed inside the separation component. After the brine shrimp eggs hatch, they are attracted to light by the light source component in the cultivation box 4 and swim into the cultivation box 4. The hatched brine shrimp eggs float on the water surface, while dead eggs and soil fall to the bottom of the separation component. After the brine shrimp eggs have hatched, the separation component is flipped by a drive motor to turn the dead eggs, hatched eggs, and soil out of the incubation box 1. This solves the problem that existing centrifuge equipment for egg shell separation technology cannot effectively collect egg shells and soil, which can easily cause blockages in subsequent operations.

[0030] Preferably, the separation component includes a separation frame 5, a collection tube 6 is provided at the bottom of the separation frame 5, and the top of the collection tube 6 is detachably connected to the top of the separation frame 5.

[0031] It should be noted that the separation frame 5 is a sieve frame. After the brine shrimp eggs are hatched, the brine shrimp are larger than the eggshell. Therefore, the upper part of the separation frame 5 is made of a large sieve to facilitate the brine shrimp swimming out of the separation frame 5 by being attracted to light. The broken shells and soil fall into the collection cylinder 6 through the bottom surface of the lower part of the separation frame 5. In addition, dead eggs remain at the bottom of the separation frame 5.

[0032] When the brine shrimp hatch, their shells either float on the water surface or sink to the bottom of the separation frame 5. The dust adhering to the outer surface of the brine shrimp eggs, or the dust on the outside, sinks into the collection tube 6 due to its own density. After the brine shrimp have finished hatching, the eggshells and soil are poured out of the incubation box 1 by flipping the separation frame 5 and the collection tube 6.

[0033] Optionally, the bottom of the separation frame 5 is provided with external threads, the collection cylinder 6 is provided with internal threads, the bottom of the separation frame 5 is threadedly connected to the top of the collection cylinder 6, and the outer circumferential surface of the collection cylinder 6 is provided with mutually symmetrical gripping rods 7.

[0034] The separation frame 5 and the collection cylinder 6 are connected by a threaded connection, making the connection between them more stable. A gripping rod 7 is provided on the side of the collection cylinder 6, which allows for manual rotation of the collection cylinder 6 and the separation frame 5 to separate the collection cylinder 6 from the separation frame 5.

[0035] Optionally, one end of the gripping rod 7 is provided with a rotating rod that extends into the collection cylinder 6 and is connected to a scraping strip 8. The other end of the scraping strip 8 is rotatably connected to the inner wall of the collection cylinder 6.

[0036] It should be noted that the outer circumference of the scraping strip 8 is equipped with a brush. By contacting the inner wall and bottom of the collection cylinder 6 with the brush, the brush can deeply clean the inner wall and bottom of the collection cylinder 6, thereby improving the cleaning quality.

[0037] Grasp one end of the gripping rod 7, and drive the rotating rod to rotate. The rotating rod drives the scraping strip 8 to rotate, and the scraping strip 8 scrapes the soil off the inner wall and bottom of the collection cylinder 6, improving the convenience of scraping the soil off the inner wall of the collection cylinder 6.

[0038] Preferably, the light source assembly includes a start-up end 9 and a light source 10. The start-up end 9 is located at the top of the incubator 4, and the light source 10 is electrically connected to its bottom. The light source 10 is located inside the incubator 4, and the start-up end 9 is connected to an external power source.

[0039] It should be noted that the starting end 9 can supply power to the light source 10 and the backup light source 24. The light intensity of the backup light source 24 is less than that of the light source 10, which makes it easier for the brine shrimp to swim into the incubation box 4 by being attracted to the stronger light.

[0040] An external power source supplies current to the starter terminal 9, which activates the lamp source 10. The lamp source 10 increases the light source in the incubator 4, making it easier to utilize the phototaxis of the brine shrimp, which then swims into the incubator 4 to complete the collection of brine shrimp.

[0041] Preferably, the incubator 1 is connected to the incubator 4 via a pyramidal tube 11. One side of the pyramidal tube 11 is open, and the other side is provided with a through hole 12.

[0042] Using a pyramidal tube 11 for communication, when the brine shrimp have hatched, they swim through the opening of the pyramidal tube 11 and through the through hole 12 into the incubation box 4.

[0043] Preferably, the incubator 4 is provided with a lifting component on its side, and the lifting component is slidably connected to the output port on the side of the incubator 4 through the sealing plate 13.

[0044] After collecting the brine shrimp, the sealing plate 13 can be slid upwards by lifting the component, opening the incubation box 4. The brine shrimp then flow into the breeding pond through this opening.

[0045] Optionally, the lifting assembly includes a zigzag handle 14 and a second fixed block 15. A toothed rack 16 is slidably connected inside the second fixed block 15. The bottom of the toothed rack is connected to a sealing plate 13. One end of the zigzag handle 14 extends into the second fixed block 15 and is provided with a gear 17. One side of the gear 17 is rotatably connected to the inner sidewall of the second fixed block 15 through an end rod. The gear 17 meshes with the toothed rack 16.

[0046] In one example, by grasping and rotating the bend handle 14, the gear 17 at the other end drives the rack 16 to slide upwards. As the rack 16 slides upwards, it causes the sealing plate 13 to slide upwards, thus opening the outlet of the incubator 4. Conversely, when the bend handle 14 is reversed, the gear 17 drives the rack 16 downwards, and the rack 16 causes the sealing plate 13 to slide towards the bottom of the outlet until the bottom of the sealing plate 13 is in close contact with the bottom of the outlet.

[0047] Optionally, the incubator 4 has a sliding groove 18 on its side. The top and side of the sealing plate 13 extend into the sliding groove 18 and are slidably connected to the inner side wall of the sliding groove 18. The side of the sealing plate 13 is connected to the bottom periphery of the sliding groove 18 through an elastic cloth 22. The bottom of the sealing plate 13 is provided with a sealing block 19. The bottom of the side of the incubator 4 is provided with a sealing groove 20 corresponding to the sealing block 19.

[0048] During the sealing process within the chute 18, the elastic cloth 22 connected to the side of the sealing plate 13 and the bottom edge of the chute 18 continuously prevents water from leaking out of the incubator 4 through the chute 18. Furthermore, a sealing block 19 is provided at the bottom of the sealing plate 13 to further prevent water leakage from the incubator 4.

[0049] Preferably, the incubator 1 is provided with a water outlet valve 21 on its side.

[0050] When the water source needs to be changed, the old water source can be output to the incubator 1 and incubator 4 by opening the outlet of the incubator 4 and the outlet valve 21 of the hatching box 1, thereby improving the water supply efficiency.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
