Description

Technical Field

[0002] Multi-barrel farming is the use of multiple large barrels for high-density farming. Through technologies such as oxygenation, constant temperature control, and water circulation, efficient farming is achieved. It also embodies the concept of environmental protection and effectively solves the problems faced in traditional farming, such as land restrictions, water shortages, and high costs, thereby improving the economic benefits of farming.

[0003] However, in actual application, especially when heating multiple breeding barrels, the existing technology is to heat hot water and let the hot water flow through the heating pipes laid in each breeding barrel to achieve overall heating. Although this method is convenient for integrated operation and simplifies the use process, it is somewhat insufficient in actual breeding practice, because different breeding barrels may raise different types of fish, and different fish require different suitable breeding temperatures. Or in the same fish breeding experiment, it is necessary to explore the water temperature conditions that are most suitable for their growth. Suitable water temperature is crucial for fish growth. It can not only promote the rapid growth of fish and increase production, but also effectively prevent the occurrence of diseases. Therefore, it is particularly important to accurately control the water temperature of each breeding barrel.

[0004] However, due to its inherent limitations, the traditional water circulation heating method is difficult to achieve differentiated temperature regulation between different breeding barrels. On the other hand, although it is possible to install a heating device in each breeding barrel to achieve personalized temperature control, this approach will lead to an increase in the overall equipment cost and bring a certain economic burden to the breeders, which is obviously not in line with actual needs.

[0055] Since the opening size of the solenoid valve 7 is controlled by the current, the required heating power is converted into the corresponding current size. The opening size of the solenoid valve 7 corresponds to the flow rate, and the opening size of the solenoid valve 7 is proportional to the current size. This relationship is affected by the heating power demand. The following calculation formula can be obtained: ,in It is expressed as the maximum current value for controlling the electromagnetic valve 7 to fully open. It is the minimum current value for controlling the opening of the solenoid valve 7 to be completely closed.

[0072] By adopting the above technical solution, the water pump 2 extracts the liquid and first introduces it into the small compartment on the left side of the heating box 1. The heating pipe 14 installed here can heat the liquid to a preliminarily set temperature range according to a preset program. During this process, the second temperature sensor 9 monitors the water temperature in the small compartment on the left in real time to ensure accurate heating. Subsequently, the liquid that has been preliminarily heated flows into the small compartment in the middle, where the heating pipe 14 further heats the liquid. The third temperature sensor 10 is responsible for monitoring the water temperature at this stage to ensure that the heating process meets the established requirements. Finally, the liquid enters the third small compartment on the right side of the heating box 1 and is deeply heated again through the heating pipe 14, while the fourth temperature sensor 11 monitors the water temperature in this final heating stage.

[0073] Through this segmented heating design, not only can the temperature of the liquid in the heating box 1 be finely controlled, but the stability and accuracy of the temperature control are also greatly improved, thereby ensuring that the liquid flowing out of the heating box 1 can be maintained within a constant target temperature range. This design effectively avoids temperature fluctuations that may occur in traditional heating methods. Segmented heating also helps to save energy because each stage only works on the part that needs to be heated, reducing unnecessary energy loss.
