[0002] Aquaculture is the use of waters available for breeding, including planting, by humans, in accordance with the ecological habits of the breeding objects and the requirements for the water environment, using aquaculture technology and facilities to engage in the breeding of aquatic economic animals and plants. As one of the agricultural production sectors, my country's coastal fishing areas have seen a boom in investment in the development of marine aquaculture cages, which has become a hot area for the development of my country's marine fisheries in recent years. Therefore, water temperature regulation has become a major problem in aquaculture, and water temperature regulation devices are needed to ensure the survival rate of the farmed animals.

[0003] For example, in the prior art, there is a water heating system for a farm with a publication number of CN208821514U. Although the heating system minimizes the damage to organisms when heating the water in the aquaculture pond, there are obvious energy efficiency problems in the hot water transportation process. In the process of transporting the heated water to the heating U-shaped pipe through the hot water pipe, due to the lack of an effective heat insulation structure in the hot water transportation process, the heat in the hot water will inevitably be lost to the surrounding environment in large quantities. In order to compensate for the large amount of heat loss, more fuel needs to be consumed to heat the water in the boiler, resulting in unnecessary energy waste;

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1: In view of the problem that in the prior art, due to the lack of an effective heat insulation structure in the hot water transportation process, a large amount of heat in the hot water is lost to the surrounding environment, and more fuel is consumed to heat the water in the boiler, thereby causing energy waste, the following solution can be used to solve the problem;

[0026] See also Figure 1 - Figure 5 As shown, the energy-saving and environment-friendly fuel boiler suitable for aquaculture in this embodiment comprises a boiler body 1, a heating tube 2 is fixedly connected inside the boiler body 1 for placing fuel, the heating tube 2 is heated by fuel combustion, and the heated heating tube 2 quickly heats the water around it, a water adding pipe 11 is fixedly connected to the top of the boiler body 1, and a sealing cover is provided at the end of the water adding pipe 11, the water adding pipe 11 is used to inject water into the boiler body 1, and then the sealing cover is covered to prevent the problem of water vapor evaporating after heating and taking away a large amount of heat, a water outlet pipe 12 is fixedly connected to the bottom of one side of the boiler body 1, and the outer side of the water outlet pipe 12 is fixedly connected to a heat preservation return pipe 14 through a connecting block 13, a heat conduction pipe 15 is fixedly connected to the free end of the water outlet pipe 12, and the free end of the heat conduction pipe 15 is fixedly connected to the bottom of the heat preservation return pipe 14, a return pipe 16 is fixedly connected to one side of the top of the boiler body 1, and the free end of the return pipe 16 is fixedly connected to the top of the heat preservation return pipe 14;

[0027] The heated water is transported to the heat pipe 15 located in the aquaculture water body through the outlet pipe 12. The surrounding aquaculture water body is heated by heating the heat pipe 15. The hot water enters the insulation return pipe 14 through the heat pipe 15, and then wraps the outer wall of the outlet pipe 12. The part of the heat carried by the return water in the insulation return pipe 14 is used to reduce the cooling effect of the outside on the outer wall of the outlet pipe 12, so as to form the heat insulation effect of the outlet pipe 12 on the hot water during the transportation process, which can effectively reduce the large amount of heat loss of the hot water during the transportation process. In addition, when the outlet pipe 12 is transported, part of the lost heat is used to insulate the return water, which can further improve the efficiency of reheating the return water, achieve energy saving effect, and avoid causing more fuel waste.

[0028] One end of the heating tube 2 passes through the outside of the boiler body 1, which makes it easy to add fuel into the heating tube 2. A sealing door 21 that is compatible with the heating tube 2 is hinged on the outer wall of the boiler body 1 to avoid the problem of part of the heat energy being lost through the feed port of the heating tube 2 when the fuel is burned. A fuel placement box 22 is provided inside the heating tube 2 for placing fuel.

[0029] U-shaped slideways 23 are symmetrically welded on the inner walls of both sides of the heating tube 2, and slide rails 24 slidably connected to the corresponding U-shaped slideways 23 are fixedly connected on the outer wall of the fuel placement box 22. The fuel placement box 22 is slidably placed on the heating tube 2, so that the fuel placement box 22 can be easily taken out, thereby facilitating the fuel to be evenly placed in the fuel placement box 22, thereby improving the uniform heating of the surrounding water body in the boiler body 1 during the fuel combustion process, eliminating the problem of excessive heat being difficult to fully utilize due to local concentration of fuel, and a plurality of ventilation holes are opened through the bottom of the fuel placement box 22, and an air inlet pipe 25 is fixedly connected on the sealing door 21 and located below the fuel placement box 22. By blowing oxygen-rich air into the bottom of the fuel placement box 22 in the heating tube 2, combined with the setting of the ventilation holes, the combustion effect of the fuel is improved, thereby improving the heating efficiency of the water in the boiler body 1.

[0030] A scraper 26 is fixedly connected to the bottom of the fuel placement box 22 on the side away from the sealing door 21 and is slidably connected to the inner wall of the heating tube 2. When the fuel placement box 22 is taken out of the heating tube 2, the scraper 26 is driven to slide and the fuel residue inside the heating tube 2 is discharged simultaneously. An insulating layer 17 is provided inside the side wall of the boiler body 1 to improve the insulation efficiency of the boiler body 1 and reduce the loss of a large amount of heat energy during the heating process.

[0031] The top of the heating tube 2 is fixedly connected with a plurality of smoke exhaust pipes 27 at equal intervals along its length direction, and the free end of the smoke exhaust pipe 27 extends to the outside of the boiler body 1 and is fixedly connected with the smoke treatment pipe 28. The exhausted smoke enters the interior of the smoke treatment device through the smoke treatment pipe 28, and the smoke is purified before being discharged, thereby achieving an environmental protection effect during the use of the boiler body 1. The smoke exhaust pipe 27 is arranged in a spiral disk shape around the annular side wall of the heating tube 2, and the smoke generated by the combustion of the fuel in the fuel placement box 22 is discharged through the spiral disk-shaped smoke exhaust pipe 27. The water body is simultaneously heated and treated with the help of the heat carried in the smoke, thereby improving the heating efficiency of the water body. The spiral disk-shaped arrangement of the smoke exhaust pipe 27 is used to increase its contact surface with the water body, thereby improving the utilization effect of the thermal energy in the smoke.

[0032] A water outlet pump 18 is fixedly connected to the water outlet pipe 12, and the heat conducting pipe 15 is arranged in a wave shape to increase the contact area between the heat conducting pipe 15 and the aquaculture water body, thereby improving the heating effect on the aquaculture water body, and a protective mesh pipe 19 is sleeved on the outer side of the heat conducting pipe 15, and the protective mesh pipe 19 is fixedly connected to the heat conducting pipe 15 through the insulation block 110. After the hot water enters the heat conducting pipe 15, the surrounding aquaculture water body is heated, and during the heating process, the protective mesh pipe 19 on the outer side of the heat conducting pipe 15 can effectively prevent the direct contact between the aquaculture products and the heat conducting pipe 15, thereby avoiding the death of aquaculture products due to high temperature and ensuring the stability and safety of the aquaculture environment.

[0033] The working process and principle of the utility model are as follows:

[0034] During use, the utility model injects water into the boiler body 1 through the water adding pipe 11, covers the sealing cover, evenly places the fuel in the fuel placing box 22, and then places the fuel placing box 22 in the heating tube 2. After the fuel is ignited and the sealing door 21 is closed, oxygen-rich air is blown into the heating tube 2 and below the fuel placing box 22 through the air inlet pipe 25, and the complete combustion of the fuel is quickly achieved in conjunction with the ventilation holes.

[0035] The heating tube 2 is heated by the combustion of the fuel in the fuel placement box 22, and the heated heating tube 2 quickly heats the surrounding water, and the smoke generated by the fuel combustion is discharged through the spiral disc-shaped smoke exhaust pipe 27, and the water is heated synchronously by the heat carried by the smoke, thereby improving the heating efficiency of the water. The exhausted smoke enters the inside of the smoke processor through the smoke treatment pipe 28, and the smoke is purified before being discharged, thereby achieving environmental protection performance during the use of the boiler body 1;

[0036] After the water body is heated, the hot water is circulated and transported in cooperation with the water outlet pump 18. The heated water is transported to the heat pipe 15 located in the aquaculture water body through the water outlet pipe 12. The heat pipe 15 is heated, so that the surrounding aquaculture water body is subjected to heat transfer heating treatment. In the heating process, the protective mesh pipe 19 on the outside of the heat pipe 15 can effectively prevent the direct contact between the aquaculture products and the heat pipe 15, thereby avoiding the problem of death of aquaculture products caused by high temperature. The hot water enters the insulation return pipe 14 through the heat pipe 15, and wraps the outer wall of the water outlet pipe 12 to form the heat insulation effect of the water outlet pipe 12 on the hot water during the transportation process, thereby reducing the large amount of heat loss of the hot water during the transportation process. When the water outlet pipe 12 is transported, part of the lost heat is used to insulate the return water. The return water in the insulation return pipe 14 flows back to the boiler body 1 through the return pipe 16 to be heated again.
