Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to an aquaculture hatching tank. Background Technology

[0002] Currently, there are many shortcomings in the hatching tanks used in the aquaculture industry.

[0003] Most water tanks have simple temperature control devices, making it difficult to accurately control the water temperature, resulting in large temperature fluctuations that affect the normal hatching of fish eggs. The oxygen supply system has a single aeration method, resulting in uneven dissolved oxygen distribution, which cannot meet the oxygen requirements of fish eggs at different developmental stages. The water circulation system cannot flexibly adjust the intensity and direction of the water flow, which can easily cause fish eggs to accumulate and be damaged by collisions. Therefore, an aquaculture hatching water tank is proposed to address the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An aquaculture hatching tank includes a tank body, a temperature control structure, an oxygen supply structure, and a water circulation structure. The upper half of the tank body is cylindrical, and a cross-shaped support is provided at the middle and bottom of the tank body. The center of the cross-shaped support has a collar structure, and the inner side of the collar is fitted and connected to the outer side of the aeration pipe. The top side of the cross-shaped support is fitted and connected to the bottom side of the hatching tank. An isolation net is provided on the outer wall of the hatching tank. A carrying rod is provided at the top of the hatching tank. A collar is also provided at the middle of the bottom plate of the cross-shaped support and the collar is fitted onto the outer side of the aeration pipe.

[0006] Preferably, the temperature control structure includes a heating element, a heat-conducting cover, and a temperature sensor. The temperature sensor is installed inside the housing, the heating element is distributed in a serpentine pattern at the bottom of the housing, and a heat-conducting cover is installed on the outside of the heating element.

[0007] Preferably, the oxygen supply structure consists of an air pump, an air pipe, an aeration disc, and an aeration pipe. The air pump is located outside the tank and is connected to the aeration disc inside the tank through the air pipe. The right end of the aeration disc is fixedly connected to the bottom left end of the aeration pipe. Multiple micropores are provided at the connection between the aeration disc and the aeration pipe. The air generated by the air pump enters the aeration disc through the air pipe and is evenly released into the water in the aeration pipe in the form of tiny bubbles through the micropores.

[0008] Preferably, the water circulation structure includes a circulating water pump installed outside the tank, one end of the outlet pipe connected to the inside of the tank, and the other end connected to the inlet of the circulating water pump through a filter box. The outlet of the circulating water pump is equipped with a second outlet pipe, one end of which is connected to the inside of an annular pipe. The annular pipe is fixed to the inside of the top of the tank by a fixing block. Multiple nozzles are provided inside the annular pipe, with the nozzle outlets facing the same direction.

[0009] Preferably, the filter box is equipped with a detachable filter frame, the filter frame has a filter screen inside the right side wall, the bottom side of the filter frame is attached to the top of the support plate, and the front and rear ends of the support plate are fixedly connected to the front and rear side walls of the filter box.

[0010] Preferably, the temperature sensor is connected to the external controller via a data line, the external controller is connected to the frequency converter group via a control line, the frequency converters inside the frequency converter group are connected to the air pump and the circulating water pump via lines, the external controller is connected to the heating tube controller via a control line, and the heating tube controller is connected to the heating tube via an electrical circuit.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) In the temperature control structure, the serpentine design of the heating tube increases the heating area. Combined with the heat conduction cover and temperature sensor, it can achieve precise control of water temperature, provide a stable and suitable temperature environment for the organism to be incubated, and effectively improve the hatching success rate.

[0012] The oxygen supply structure, through the coordinated operation of air pumps, air pipes, aeration discs, and aeration pipes, releases air evenly into the water in the form of tiny bubbles, increasing the contact area between oxygen and water, improving dissolved oxygen efficiency, ensuring that the organisms to be hatched receive sufficient oxygen during their growth, and promoting their healthy development.

[0013] The water circulation structure utilizes a circulating water pump and a filter box to achieve water circulation and purification. The removable filter frame facilitates the cleaning of impurities and maintains the filtration effect. The even spray from the nozzles ensures more uniform water flow, providing a good living environment for the hatching organisms, reducing the frequency of water changes, and lowering operating costs and labor intensity.

[0014] The box has a reasonable structural design. The cross bracket and collar structure ensure a stable connection between the incubation tank and the aeration pipe. The handle makes it easy to operate the incubation tank. The overall equipment is simple to operate and highly practical. Attached Figure Description

[0022] Please see Figure 1-3 An embodiment of this utility model provides: an aquaculture hatching tank, including a tank body 1, a temperature control structure, an oxygen supply structure, and a water circulation structure. The upper half of the tank body 1 is cylindrical. The middle and bottom ends of the tank body 1 are provided with cross supports 4. The center of the cross support 4 is a collar structure. The inner side of the collar is attached to the outer side of the aeration pipe 24. The top side of the cross support 4 is attached to the bottom side of the hatching bucket 61. The outer wall of the hatching bucket 61 is provided with an isolation net 62. The top of the hatching bucket 61 is provided with a carrying rod 63. The carrying rod 63 and the middle of the bottom plate of the cross support 4 are also provided with collars. The collars are sleeved on the outer side of the aeration pipe 24.

[0023] The temperature control structure includes a heating tube 51, a heat-conducting cover 52, and a temperature sensor 53. The temperature sensor 53 is installed inside the housing 1. The heating tube 51 is distributed in a serpentine pattern at the bottom of the housing 1. The heating tube 51 is equipped with a heat-conducting cover 52 on its outer side.

[0024] The oxygen supply structure consists of an air pump 21, an air pipe 22, an aeration disc 23, and an aeration pipe 24. The air pump 21 is located outside the tank 1 and is connected to the aeration disc 23 inside the tank 1 through the air pipe 22. The right end of the aeration disc 23 is fixedly connected to the bottom left end of the aeration pipe 24. Multiple micropores are provided at the connection between the aeration disc 23 and the aeration pipe 24. The air generated by the air pump 21 enters the aeration disc 23 through the air pipe 22 and is evenly released into the water in the aeration pipe 24 in the form of tiny bubbles through the micropores.

[0025] The water circulation structure includes a circulating water pump 32 installed outside the tank 1. One end of the outlet pipe 30 is connected to the inside of the tank 1, and the other end is connected to the inlet of the circulating water pump 32 through the filter box 31. The outlet of the circulating water pump 32 is equipped with a second outlet pipe 33. One end of the second outlet pipe 33 is connected to the inside of the annular pipe 34. The annular pipe 34 is fixed to the inside of the top of the tank 1 by a fixing block 36. Multiple nozzles 35 are provided inside the annular pipe 34, and the outlet of the nozzles 35 faces the same direction.

[0026] The filter box 31 is equipped with a detachable filter frame 311. A filter screen 312 is installed inside the right side wall of the filter frame 311. The bottom side of the filter frame 311 is attached to the top of the support plate 313. The front and rear ends of the support plate 313 are fixedly connected to the front and rear side walls of the filter box 31.

[0027] In use, first place the organism to be incubated in the incubation bucket 61. The incubation bucket 61 is stably fixed to the aeration pipe 24 by the cross bracket 4, and the handle 63 makes it easy to move the incubation bucket 61. Then fill the box 1 with water, and the water level should cover the incubation bucket 61 and all functional components.

[0028] When the temperature control structure is activated, the temperature sensor 53 monitors the water temperature inside the chamber 1 in real time. If the water temperature is lower than the set value, the heating tube 51 starts to work. The serpentine distribution of the heating tube 51 increases the contact area with the water, and the generated heat is evenly conducted to the water through the heat conduction cover 52, so that the water temperature is maintained within a suitable range.

[0029] When the oxygen supply structure is activated, the air pump 21 delivers air to the aeration disc 23 through the air pipe 22. Under the action of the micropores at the connection between the aeration disc 23 and the aeration pipe 24, the air is evenly released into the water in the aeration pipe 24 in the form of tiny bubbles, replenishing the water with oxygen and meeting the respiratory needs of the organisms to be hatched.

[0030] When the water circulation structure is activated, the circulating water pump 32 runs, and the water in the tank 1 flows into the filter box 31 through the outlet pipe 30. In the filter box 31, the water passes through the filter screen 312 in the detachable filter frame 311, and impurities are filtered and intercepted. The filtered water is then transported by the circulating water pump 32 through the second outlet pipe 33 to the ring pipe 34, and then evenly sprayed back into the tank 1 through multiple nozzles 35 on the ring pipe 34, thus realizing the circulation and purification of the water.
