Description

Technical Field

[0001] The utility model relates to the technical field of pig breeding equipment, in particular to a hot air blower device for pig breeding. Background Technique

[0002] The pig breeding industry is an important industry in China's agriculture. It plays an important role in ensuring the safe supply of meat food. China's pig breeding industry is transforming from a traditional one to a modern one. Significant changes have taken place in both the breeding mode, regional layout and production mode, production capacity. When breeding pigs, it is necessary to control the temperature of the pigsty. In winter, it is necessary to heat the pigsty to increase the temperature of the pigsty, and at the same time, it is necessary to meet the ventilation of the pigsty to avoid excessive bacteria and viruses in the air.

[0003] Existing hot air blower devices all heat the original air in the pigsty to increase the temperature of the pigsty. In order to ensure a constant temperature, the ventilation volume becomes less, resulting in a large amount of harmful gases, bacteria and viruses accumulating in the pigsty, endangering the health of pigs and reducing the meat yield of pigs. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a hot air blower device for pig breeding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A hot air blower device for pig breeding, including a mounting seat. Three ventilation pipes are detachably connected to the middle of the mounting seat. A throat tube is fixedly connected to the middle of the ventilation pipe. Both ends of the throat tube are fixedly connected with a convergent-divergent tube. An air inlet pipe is fixedly connected to the upper side of one end of the throat tube close to the first fan blade, and the upper end of the air inlet pipe passes through the ventilation pipe. A disinfectant spray pipe is fixedly connected to the lower side of the other end of the throat tube far from the first fan blade, and the lower end of the disinfectant spray pipe passes through the ventilation pipe. A first mounting rack is fixedly connected to the inside of one end of the ventilation pipe. A first motor is fixedly connected to the middle of the first mounting rack, and the output end of the first motor faces the throat tube. The output end of the first motor is fixedly connected with a first fan blade. A heating coil is fixedly connected to the inside of the other end of the ventilation pipe. First filter nets are threadedly connected to both ends of the ventilation pipe.

[0006] As a further description of the above technical solution:

[0007] The mounting seats are all located between the convergent-divergent tube and the first fan blade on the outer surface of the ventilation pipe. Through an external tool, the mounting seats are installed on the pigsty wall, so that one end of the ventilation pipe passes through the pigsty and extends into the pigsty interior.

[0008] As a further description of the above technical solution:

[0009] One end of the disinfectant spray pipe passing through the ventilation pipe is fixedly connected to a liquid storage bucket, and the disinfectant spray pipe is located at the lower end inside the liquid storage bucket. One side of the upper end of the liquid storage bucket is fixedly connected to a water injection pipe. The end of the water injection pipe away from the liquid storage bucket is threadedly connected to a sealing cover. By removing the sealing cover, disinfectant can be injected into the liquid storage bucket through the water injection pipe. The disinfectant can be used to disinfect pigs, and multiple disinfectants can be recycled.

[0010] As a further description of the above technical solution:

[0011] One end of the air inlet pipe passing through the ventilation pipe is fixedly connected to a main air pipe. The upper end of the main air pipe is threadedly connected to a third filter screen. Inside the main air pipe, a second mounting bracket is fixedly connected. In the middle of the second mounting bracket, a second motor is fixedly connected, and the output end of the second motor faces the air inlet pipe. The output end of the second motor is fixedly connected to a second fan blade. The air inlet pipe extends to the upper end of the pigsty. The air temperature above the pigsty is higher than the air temperature at the lower end of the pigsty. By driving the second fan blade to rotate through the second motor, the air in the middle of the main air pipe can quickly enter the air inlet pipe and then enter the throat pipe along the air inlet pipe. When the air in the middle of the main air pipe enters the air inlet pipe, the pressure inside the main air pipe becomes smaller, causing the air above the pigsty to enter the main air pipe.

[0012] As a further description of the above technical solution:

[0013] One end of the ventilation pipe away from the first fan blade is hinged with a protective cover. Inside the ventilation pipe at the end away from the ventilation pipe, a drying box is slidably connected, and the drying box is located directly below the protective cover. Both ends of the drying box are threadedly connected to second filter screens. Filtering materials are arranged inside the drying box. By rotating the protective cover, the drying box can be removed.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the present utility model, first, the first motor drives the first fan blade to rotate, enabling the low-temperature air from the outside to enter the ventilation pipe. The air flows along the contraction-diffusion pipe into the throat pipe and accelerates towards the other set of contraction-diffusion pipes. During this process, according to the Venturi effect, the gas inside the air inlet pipe will accelerate and flow into the throat pipe. By driving the second fan blade to rotate with the second motor, the air from the outside can enter the main air pipe, causing the air in the middle of the main air pipe to quickly enter the air inlet pipe and then flow towards the heating coil along with the cold air. The air passing through the heating coil will be heated, increasing the temperature of the gas finally entering the pigsty, thereby maintaining the temperature of the pigsty. At the same time, a large amount of outside gas enters the pigsty, maintaining ventilation inside the pigsty, diluting a large amount of harmful gases inside the pigsty, and reheating the gas at the upper end of the pigsty can achieve an energy-saving effect.

[0016] 2. In the present utility model, during the process of the cold air flowing inside the throat pipe, the liquid inside the liquid storage barrel will flow along the disinfectant spray pipe into the throat pipe and be atomized by the high-pressure and high-speed gas, thereby disinfecting the cold air entering the throat pipe and the air at the upper end of the pigsty. The disinfected gas will pass through the drying box for filtration and further sterilization, thus removing a part of the bacteria and viruses originally inside the pigsty and also removing the bacteria and viruses in the fresh air entering the pigsty, preventing the excessive growth of bacteria and viruses even at a suitable temperature and ensuring the health of the fattening pigs.

[0026] Refer to Figures 1-5 As shown in [figure reference], an embodiment provided by the present utility model: a hot air blower device for pig breeding, including a mounting base 1. Three ventilation pipes 2 are detachably connected to the middle of the mounting base 1. A throat pipe 12 is fixedly connected to the middle of the ventilation pipe 2. Converging-diverging pipes 13 are fixedly connected to both ends of the throat pipe 12. An air inlet pipe 6 is fixedly connected to the upper side of one end of the throat pipe 12 close to the first fan blade 16, and the upper end of the air inlet pipe 6 passes through the ventilation pipe 2. A disinfectant spray pipe 4 is fixedly connected to the lower side of the other end of the throat pipe 12 away from the first fan blade 16, and the lower end of the disinfectant spray pipe 4 passes through the ventilation pipe 2. A first mounting bracket 14 is fixedly connected to the inside of one end of the ventilation pipe 2. A first motor 15 is fixedly connected to the middle of the first mounting bracket 14, and the output end of the first motor 15 faces the throat pipe 12. A first fan blade 16 is fixedly connected to the output end of the first motor 15. A heating coil 9 is fixedly connected to the inside of the other end of the ventilation pipe 2. First filter nets 8 are threadedly connected to both ends of the ventilation pipe 2.

[0027] One end of the ventilation pipe 2 away from the first fan blade 16 is hinged with a protective cover 3. Inside the ventilation pipe 2, a drying box 10 is slidably connected at the end away from the ventilation pipe 2, and the drying box 10 is located directly below the protective cover 3. Both ends of the drying box 10 are threadedly connected with second filter nets 11. A filtering material is arranged inside the drying box 10. By rotating the protective cover 3, the drying box 10 can be removed. Then, a set of second filter nets 11 is removed, and the filtering material inside the drying box 10 is replaced. After that, the drying box 10 is reinstalled inside the ventilation pipe 2 and the protective cover 3 is covered, which can remove bacteria and viruses in the air. One end of the air inlet pipe 6 passing through the ventilation pipe 2 is fixedly connected with a main air pipe 7. The upper end of the main air pipe 7 is threadedly connected with a third filter net 22. Inside the main air pipe 7, a second mounting bracket 19 is fixedly connected. In the middle of the second mounting bracket 19, a second motor 20 is fixedly connected, and the output end of the second motor 20 faces the air inlet pipe 6. The output end of the second motor 20 is fixedly connected with a second fan blade 21. The air inlet pipe 6 extends to the upper end of the pigsty. The air temperature above the pigsty is higher than the air temperature at the lower end of the pigsty. By driving the second fan blade 21 to rotate through the second motor 20, the air in the middle of the main air pipe 7 quickly enters the air inlet pipe 6 and enters the throat pipe 12 along the air inlet pipe 6. When the air in the middle of the main air pipe 7 enters the air inlet pipe 6, the pressure inside the main air pipe 7 becomes smaller, causing the gas above the pigsty to enter the main air pipe 7. The mounting seats 1 are all located between the converging-diverging pipe 13 and the first fan blade 16 on the outer surface of the ventilation pipe 2. Through an external tool, the mounting seats 1 are installed on the pigsty wall, so that one end of the ventilation pipe 2 passes through the pigsty and extends into the pigsty. One end of the disinfectant spray pipe 4 passing through the ventilation pipe 2 is fixedly connected with a liquid storage bucket 5, and the disinfectant spray pipe 4 is located at the lower end inside the liquid storage bucket 5. One side of the upper end of the liquid storage bucket 5 is fixedly connected with a water injection pipe 17. The end of the water injection pipe 17 away from the liquid storage bucket 5 is threadedly connected with a sealing cover 18. By removing the sealing cover 18 and injecting disinfectant into the liquid storage bucket 5 through the water injection pipe 17, the disinfectant can disinfect the pigs, and multiple disinfectants can be recycled.

[0028] Working principle: When in use, install the mounting base 1 at the lower end of the pigsty wall, so that the ventilation pipe 2 passes through the wall and extends into the lower end inside the pigsty. Hot air flows from bottom to top, and the gas temperature at the upper end of the pigsty is higher than that at the lower end. Rotate the protective cover 3 to remove the drying box 10, then remove a set of second filter meshes 11, replace the filtering material inside the drying box 10, and then install the drying box 10 back into the ventilation pipe 2 and cover the protective cover 3, which can remove bacteria and viruses in the air. Remove the sealing cover 18 and inject disinfectant into the liquid storage bucket 5 through the water injection pipe 17. The disinfectant can disinfect the pigs, and multiple disinfectants can be recycled. Drive the first fan blade 16 to rotate through the first motor 15, so that the low-temperature air outside enters the ventilation pipe 2. The air enters the throat pipe 12 along the contraction-diffusion pipe 13 and accelerates towards the other set of contraction-diffusion pipes 13. In this process, according to the Venturi effect, the gas inside the air inlet pipe 6 will accelerate and flow into the throat pipe 12. Drive the second fan blade 21 to rotate through the second motor 20, so that the outside air can enter the main air pipe 7, and the air in the middle of the main air pipe 7 can quickly enter the air inlet pipe 6. The liquid in the liquid storage bucket 5 will flow along the disinfectant spray pipe 4 into the throat pipe 12 and be atomized by the high-pressure and high-speed gas, so as to disinfect the cold air entering the throat pipe 12 and the air at the upper end of the pigsty. The disinfected gas will pass through the drying box 10 for filtration and sterilization again, so as to remove part of the original bacteria and viruses inside the pigsty and the bacteria and viruses in the fresh air entering the pigsty, avoiding excessive bacteria and viruses even at a suitable temperature, ensuring the health of the fattening pigs. Then it will flow towards the heating coil 9 along with the cold air. The air passing through the heating coil 9 will be heated, so that the temperature of the gas finally entering the pigsty increases, thus maintaining the temperature of the pigsty. At the same time, a large amount of outside gas enters the pigsty, keeping the ventilation inside the pigsty, diluting a large amount of harmful gases inside the pigsty, and reheating the gas at the upper end of the pigsty can achieve the effect of energy conservation.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
