Description

Technical Field

[0001] The present invention relates to the field of aquaculture equipment, and more particularly to an oyster seed cultivation system. Background Art

[0002] At present, most of the oyster seedlings are cultivated in cement ponds. To ensure the normal reproduction of oyster seedlings, it is necessary to ensure the water quality and oxygen content in the water for cultivation. In response to these requirements, cement ponds can be used to cultivate oyster seedlings in large water bodies. While meeting the water quality requirements, the oxygen concentration in the water can also meet the standards. However, the use of cement ponds as a cultivation facility and method occupies a large area and consumes a lot of water, and the workload brought about by the subsequent equipment maintenance and bait feeding is also very large. Although the oyster seedlings can grow normally, the utilization rate of water resources and bait is very low, which is contrary to the development direction of modern agricultural equipment and facilities.

[0003] Therefore, how to provide an oyster seed cultivation system that can overcome the above problems is an urgent problem that those skilled in the art need to solve. Summary of the Invention

DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] The present invention discloses an oyster seed cultivation system. The present invention is designed with a tank body 1, a tank body 2 3, a tank body 3 5, a water outlet pipe 4, an annular filter cotton 7 and a water pump 9. Oyster seedlings can be placed in the tank body 2 3. The water in the tank body 2 3 always flows stably from top to bottom. After passing between the inner wall of the tank body 1 and the outer wall of the tank body 2 3, the water in the tank body 2 3 overflows from the upper end of the tank body 1. Due to the overflow method, the contact area of ​​the water with the air is increased during the downward overflow process, so that the oxygen content of the water body is sufficient; the water overflowing from the tank body 1 is filtered by the annular filter cotton 7, which reliably intercepts larval excrement. The annular filter cotton 7 will not be immersed in the water body, so that the impurities intercepted on the annular filter cotton 7 will not pollute the water body for a long time, thereby ensuring the water quality and being suitable for high-density cultivation of oyster seedlings.

[0024] The design of the frustum 2 allows impurities in the water of tank 2 (3) to sink and collect on the periphery of the lower bottom surface of the frustum 2. These impurities rise with the water flow and are ultimately removed from the upper end of tank 1 (1). Impurities do not accumulate on the inner bottom wall of tank 1 (1). Because the water in tanks 1 (1), 2 (3), and 3 (5) circulates, the water consumption of the entire cultivation system is low.

[0025] The design of the annular aeration stone 10, on the one hand, ensures that the oxygen content of the water in the entire system is sufficient to meet the normal growth and development of the oyster seedlings; on the other hand, the bubbles uniformly discharged by the annular aeration stone 10 will move impurities in the water upward during the rising process, ensuring that the impurities can be reliably discharged from the tank body 1;

[0026] The design of the annular guide cover 8 and the retaining ring 12 ensures that the water overflowing from the tank body 1 can effectively pass through the annular filter cotton 7;

[0027] The residual bait microalgae in the water in tank body three 5 will be rejuvenated by the blue waterproof LED light 15, and then pumped again into tank body one 1 and tank body two 3 through the water pump 9.

[0028] Example

[0029] See attached Figure 1-5 Schematic diagram of the overall and partial structures of one embodiment of the present invention, which specifically discloses an oyster seed cultivation system, including: a tank body 1, a truncated cone body 2, a tank body 2, a water outlet pipe 4, a tank body 3, an annular orifice plate 6, an annular filter cotton 7, an annular flow guide cover 8, and a water pump 9. The tank body 1, the tank body 2, the water outlet pipe 4, and the tank body 3, 5 are all arranged vertically.

[0030] The cylindrical tank has an opening at the top.

[0031] The lower bottom surface of the frustum 2 is coaxially fixed to the inner bottom wall of the tank body 1. A circular water inlet hole is opened in the center of the bottom wall of the tank body 1. The frustum 2 is provided with a water inlet channel that passes through its upper and lower bottom surfaces. The water inlet channel corresponds to and is connected to the water inlet hole. Since the frustum 2 has an inclined side surface, impurities in the water of the tank body 1 will accumulate on the periphery of the lower bottom surface of the frustum 2 when sinking.

[0032] The lower end of the cylindrical tank body 2 (3) is open and coaxially arranged within the tank body 1. The oyster seed is arranged within the tank body 2 (3). The upper end of the tank body 2 (3) is arranged above the upper end of the tank body 1. The lower end wall of the tank body 2 (3) corresponds vertically to the oblique side surface of the frustum (2) and has a gap therebetween. That is, water in the tank body 2 (3) can flow through the gap into the space between the inner wall of the tank body 1 and the outer wall of the tank body 2 (3).

[0033] The upper end of the outlet pipe 4 with a circular cross-sectional outer contour is coaxially fixed to the inner wall of the upper end of the tank body 2 3, and the lower end of the outlet pipe 4 is coaxially and tightly abutted with the upper bottom surface of the truncated cone body 2. The water inlet channel is connected to the outlet pipe 4, and a plurality of outlets 40 are opened on the side wall of the outlet pipe 4. The outlets 40 are arranged near the upper end of the outlet pipe 4; the water flowing out of the outlet 40 can first flow downward, and then return upward after passing through the gap formed by the lower end wall of the above-mentioned tank body 2 3 and the oblique side surface of the truncated cone body 2, and finally overflow from the upper end of the tank body 1. The oyster seedlings are attached to the tank body 2 3 and will not move out from the above-mentioned gap. If necessary, an annular filter can be detachably embedded between the inner wall of the tank body 1 and the outer wall of the tank body 2 3. The annular filter can intercept the oyster seedlings, larvae excrement and residual bait microalgae in the water will pass through the annular filter;

[0034] The top of the tank body 3 5 is open, and the lower end of the tank body 1 is coaxially arranged inside the tank body 3 5. External purified source water can be added from the open end of the tank body 3 5. The side wall of the tank body 3 5 is provided with a vertically arranged long hole, which is sealed with glass. The water level inside the tank body 3 5 can be observed through the vertically arranged long hole.

[0035] The annular orifice plate 6 is coaxially fixed in the tank body 3 5, the tank body 1 is limited on the inner side of the annular orifice plate 6, and the annular filter cotton 7 is coaxially laid on the annular orifice plate 6;

[0036] The outer contour of the annular flow guide cover 8 is truncated cone-shaped. The inner side wall of the annular flow guide cover 8 is tightly fixed to the outer side wall of the tank body 1. The outer side wall of the annular flow guide cover 8 is vertically aligned with the annular filter cotton 7. The water overflowing from the tank body 1 will be guided by the annular flow guide cover 8 and flow down directly above the annular filter cotton 7. The annular filter cotton 7 will intercept the larval excrement in the water, and the residual bait microalgae in the water will pass through the annular filter cotton 7.

[0037] The water pump 9 is arranged in the tank body 3 5 and its water outlet is connected to the water inlet through a water pipe.

[0038] More specifically, it also includes an annular aeration stone 10 and an air pump 11. The inner bottom wall of the tank body 1 is coaxially provided with an annular groove. The frustum body 2 is limited inside the annular groove. The annular aeration stone 10 is embedded in the annular groove. The annular aeration stone 10 is arranged between the outer wall of the tank body 2 3 and the inner wall of the tank body 1; the air pump 11 is fixed to the upper end of the tank body 2 3. The air pump 11 is connected to the annular aeration stone 10 through an air pipe. The air pump 11 pumps air to the annular aeration stone 10, and the annular aeration stone 10 will produce bubbles that rise evenly. The bubbles are in the tank body 1 1 and the outer wall of the tank body 3. On the one hand, this design can oxygenate the water and ensure the oxygen supply of the oyster seedlings. On the other hand, the frustum 2 is limited to the inner side of the annular aeration stone 10. Impurities in the tank body 1 will gather above the annular aeration stone 10. When the bubbles float up, they will further drive the impurities to move upward, which helps to discharge the impurities from the tank body 1. At the same time, the annular aeration stone 10 is always in an aerated state, the surface of the annular aeration stone 10 will not be blocked, and impurities will not accumulate on the outer periphery of the bottom surface of the frustum 2 and remain motionless.

[0039] A retaining ring 12 is coaxially fixed to the upper plate surface of the annular orifice plate 6. The retaining ring 12 is arranged between the outer wall and the inner wall of the annular air guide cover 8. The upper end of the retaining ring 12 is arranged higher than the upper surface of the annular filter cotton 7. The water overflowing from the tank body 1 can reliably pass through the annular filter cotton 7.

[0040] A plurality of connecting plates 13 are evenly distributed and fixed around the inner wall of tank body three 5. One end of the plurality of connecting plates 13 away from the inner wall of tank body three 5 is fixed to the outer wall of tank body one 1, so that tank body one 1 and tank body three 5 can be reliably fixed together.

[0041] A plurality of limit plates 14 are evenly distributed and fixed around the outer wall of the second tank body 3 . The limit plates 14 are arranged horizontally and their lower surfaces are detachably fixed to the upper end wall of the first tank body 1 . The limit plates 14 can limit the vertical movement of the second tank body 3 .

[0042] More specifically, a blue waterproof LED light 15 is also included, secured to the inner bottom wall of tank body 3 5 . Water filtered by annular filter 7 flows into tank body 3 5 , where residual microalgae are rejuvenated by the blue waterproof LED light 15 before being pumped back into tank body 1 1 and tank body 2 3 via water pump 9 .

[0043] A through hole is provided on the top of the second tank body 3 , and a cover plate 16 is detachably sealed at the through hole. The cover plate 16 can be opened to add purified water or put oyster larvae into the second tank body 3 .

[0044] When the cultivation system is working, the water pump 9 pumps the water in the tank body 3 5 into the tank body 1 1 and the tank body 2 3. Since the water outlet 40 is arranged in the tank body 2 3 and close to the top of the tank body 2 3, the water discharged from the water outlet 40 will flow downward, and then return upward after passing through the gap formed by the lower end wall of the above-mentioned tank body 2 3 and the inclined side surface of the frustum body 2, and finally overflow from the upper end of the tank body 1 1. The water flow direction in the tank body 2 3 is constant. Due to the frustum body 2, when the water in the tank body 2 3 flows downward, the impurities in the water will not stay on the inner bottom wall of the tank body 1 1, and will smoothly overflow from the top of the tank body 1 1, and the aeration of the annular aeration stone 10 makes the oxygen content of the water in the tank body 1 1, the tank body 2 3 and the tank body 3 5 sufficient; the liquid level of the water in the tank body 3 5 is below the annular orifice plate 6, so the impurities intercepted on the annular filter cotton 7 will not be soaked in water for a long time, avoiding water deterioration.

[0045] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0046] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention.
