Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an oxygenation device for shrimp larvae farming. Background Technology

[0002] Aquaculture is the production and operation of aquatic economic animals and plants raised by humans in suitable waters, according to the ecological habits of the aquatic organisms and their requirements for aquatic environmental conditions. It is a sector of agricultural production. Aquaculture is divided into marine aquaculture and freshwater aquaculture based on the nature of the water body. Based on the aquatic organisms being raised or cultivated, it includes fish, shrimp, crabs, shellfish, algae, water chestnuts, lotus, and lotus roots, etc. Aquaculture is a production and operation that utilizes suitable waters to raise aquatic economic animals and plants. It is an important part of fisheries. Humans started engaging in aquaculture later than the fishing industry, which harvests natural aquatic resources. The emergence and development of aquaculture marks the enhancement of human beings' ability to influence and control waters.

[0003] Shrimp, as an important economic aquatic product, occupies a significant position in global aquaculture. Shrimp larvae rearing is a crucial link in the entire shrimp farming process, and its quality directly affects the growth rate, survival rate, and final yield of adult shrimp. Shrimp larvae are extremely sensitive to environmental factors such as water quality, temperature, and dissolved oxygen during their growth process, especially dissolved oxygen levels. In high-density farming environments, the demand for dissolved oxygen is even more urgent. Insufficient dissolved oxygen can lead to slow growth and decreased immunity in shrimp larvae, and even cause large-scale mortality, resulting in huge economic losses for farmers. To address these issues, we propose an aeration device for shrimp larvae rearing. Utility Model Content

[0004] The purpose of this invention is to provide an oxygenation device for shrimp larvae farming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An aeration device for shrimp larvae farming includes a fixed plate, a farming frame fixedly connected to the upper surface of the fixed plate, an air pump fixedly installed on the right side of the farming frame, two support seats fixedly connected to the bottom surface of the fixed plate, a discharge pipe fixedly connected to the bottom surface of the fixed plate, a valve fixedly connected to the outer surface of the discharge pipe, a filter frame inside the farming frame, two sets of dissolved oxygen sensors fixedly installed on the upper surface of the filter frame, a first filter screen fixedly installed on the inner side wall of the filter frame, two lifting handles fixedly connected to the upper surface of the filter frame, two guide plates fixedly connected to the upper surface of the fixed plate, a microporous aeration disc fixedly connected to the upper surface of each guide plate, a connecting pipe fixedly connected to the inner side wall of the farming frame, and the connecting pipe communicating with the microporous aeration disc, the air inlet end of the connecting pipe being fixedly connected to the air outlet end of the air pump.

[0007] In a further embodiment, two reinforcing strips are fixedly connected to the upper surface of the fixing plate. The two reinforcing strips are fixedly connected to the front and back of the air pump respectively on their sides that are close to each other. The left side of each reinforcing strip is fixedly connected to the right side of the breeding frame.

[0010] In a further embodiment, the inner sidewall of the breeding frame is provided with two sets of guide grooves, and each guide groove is slidably connected to a guide block. The sides of the two sets of guide blocks that are close to each other are fixedly connected to the left and right sides of the filter frame, respectively.

[0011] In a further embodiment, a second filter screen is provided between the two guide plates, and the left and right ends of the second filter screen are fixedly connected to one side of the guide plate that is close to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device releases air into the water as tiny bubbles through a microporous aeration disc, increasing the contact area between air and water and thus significantly improving dissolved oxygen levels. This meets the dissolved oxygen requirements of shrimp larvae in high-density aquaculture environments. The combination of a filter frame, a first filter, and a second filter effectively filters impurities and shrimp excrement from the water, preventing clogging of the microporous aeration disc and protecting the shrimp from harm. This ensures stable operation of the aeration system. A dissolved oxygen sensor monitors the dissolved oxygen content in the water in real time and feeds the data back to the control system, automatically adjusting the air pump for precise aeration and energy savings. The guide trough and guide blocks facilitate cleaning of the filter frame. The discharge pipe and valves allow for the regular discharge of wastewater and pollutants from the aquaculture water, maintaining water quality and providing a favorable growth environment for the shrimp larvae.
