[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] This utility model provides a ventilation and air exchange device for pig farming, such as... Figure 1-4As shown, the ventilation and air exchange device for pig farming includes: a mounting box 1; a treatment box 2, which is fixedly installed on the mounting box 1 for gas treatment; a guide pipe 3, which is fixedly installed inside the mounting box 1 and extends into the treatment box 2; an air inlet pipe 4, one end of which is fixedly installed on the guide pipe 3, and the other end of which extends into the pigsty; a fan 5, which is fixedly installed inside the guide pipe 3; a liquid inlet pipe 6, which is fixedly installed on the top of the treatment box 2 and fixedly connected to a water tank containing deodorizing liquid; a nozzle 7, which is fixedly installed on the liquid inlet pipe 6; an exhaust pipe 8, which is fixedly installed on the top of the treatment box 2; and a pigsty air intake mechanism, which is located inside the mounting box 1 and is used to inject fresh gas into the pigsty.
[0022] In this embodiment, one end of the air inlet pipe 4 is placed inside the pigsty. When the fan 5 is activated, the gas from the pigsty is drawn into the treatment box 2 through the guide pipe 3. Simultaneously, deodorizing liquid is delivered to the nozzle 7 through the liquid inlet pipe 6 and sprayed into the treatment box 2 to contact the inhaled gas, removing odors and some harmful gases. The treated gas is then discharged through the exhaust pipe 8. The pigsty air intake mechanism injects fresh gas into the pigsty, achieving air renewal. Through effective ventilation, the temperature and humidity inside the pigsty are regulated, harmful gases such as ammonia and hydrogen sulfide are expelled, dust and pathogenic microorganisms are reduced, and the risk of respiratory diseases and other infectious diseases in pigs is lowered, ensuring the healthy growth of pigs. This device, through deodorizing liquid treatment, effectively removes odors generated during pig farming, improves the environment inside the pigsty, and protects the health of both humans and pigs. The various components work together to achieve effective treatment and circulation of gas within the pigsty, providing excellent ventilation conditions for pig farming.
[0023] In a further preferred embodiment of this utility model, the pigsty air intake mechanism includes a fan 9, an air inlet pipe 10, a fixing cover 11, and a ventilation pipe 12. The fan 9 is fixedly installed inside the mounting box 1. The air inlet pipe 10 is fixedly installed at the air inlet end of the fan 9 and extends to the outside of the mounting box 1. The fixing cover 11 is fixedly installed inside the mounting box 1 and is fixedly connected to the exhaust end of the fan 9. The ventilation pipe 12 is fixedly installed on the fixing cover 11 and extends into the pigsty.
[0024] In this embodiment, when the fan 9 is activated, fresh outside air is drawn into the mounting box 1 through the air inlet pipe 10. The drawn-in fresh air enters the fixed cover 11 through the exhaust end of the fan 9. After being collected in the fixed cover 11, the fresh air is injected into the pigsty through the ventilation pipe 12, thus replenishing the fresh gas in the pigsty. The pigsty air intake mechanism works in conjunction with the original ventilation and air exchange device. The setting of the fan 9 increases the power of airflow, enabling fresh air to be injected into the pigsty more quickly and effectively, further improving the ventilation and air exchange capacity of the pigsty. This helps to better regulate the temperature and humidity in the pigsty, expel harmful gases, and reduce the accumulation of dust and pathogenic microorganisms. The fan model is a 9-26 centrifugal fan. By continuously injecting fresh gas into the pigsty, a better growth environment is provided for the pigs, effectively reducing the risk of respiratory diseases and other infectious diseases in pigs, ensuring the healthy growth of pigs, and thus improving breeding efficiency.
[0025] In a further preferred embodiment of the present invention, an electronic cooling chip 13 is fixedly installed on the side wall of the fixed cover 11, and cooling fins 14 are fixedly installed at both ends of the electronic cooling chip 13, wherein one side of the cooling fin 14 is correspondingly arranged with the exhaust end of the fan 9.
[0026] In this embodiment, when it is necessary to cool the fresh air entering the pigsty, the electronic cooling element 13 is activated. After the electronic cooling element 13 is activated, it generates cooling at both ends, which is dissipated and cooled through the cooling fins 14 fixed at both ends. One side of the cooling fin 14 is positioned corresponding to the exhaust end of the fan 9. The fresh air exhausted by the fan 9 passes through this cooling fin 14, exchanging heat with it and thus lowering its temperature. The cooled fresh air is collected within the fixed cover 11 and then injected into the pigsty through the ventilation pipe 12. In hot weather or when the temperature inside the pigsty is too high, the electronic cooling element 13 and the cooling fins 14 can cool the fresh air entering the pigsty, helping to regulate the temperature inside the pigsty, providing a more suitable growth environment for the pigs, reducing stress caused by high temperatures, and ensuring the health and growth performance of the pigs. The introduction of cooled fresh air into the pigsty can more effectively reduce the overall temperature inside the pigsty. At the same time, in conjunction with the existing ventilation system, it can further improve the air quality inside the pigsty, enhance the ventilation effect, and reduce the accumulation of harmful gases and pathogenic microorganisms.
[0027] In a further preferred embodiment of the present invention, a fixing frame 15 is fixedly installed on the mounting box 1, and a cooling fan 16 is fixedly installed on the fixing frame 15. The cooling fan 16 is correspondingly arranged with the cooling fins 14 on the other side of the electronic cooling chip 13.
[0028] In this embodiment, when the electronic cooling chip 13 is activated to cool the fresh air entering the pigsty, the cooling fins 14 on its other side will generate heat. At this time, the cooling fan 16 is activated simultaneously. Since the cooling fan 16 is correspondingly positioned to the cooling fins 14 on the other side of the electronic cooling chip 13, the cooling fan 16 will generate airflow, accelerating the airflow around the cooling fins 14 on that side. Under the action of the airflow generated by the cooling fan 16, the heat on the cooling fins 14 is quickly carried away and dissipated into the surrounding environment, thereby ensuring that the electronic cooling chip 13 can work continuously and stably, maintain a good cooling effect, and avoid performance degradation or even damage to the electronic cooling chip 13 due to overheating. This ensures that the electronic cooling chip 13 can continuously and stably provide cooling for the fresh air entering the pigsty, guaranteeing the stability of the pigsty temperature regulation. The mounting bracket 15 facilitates the installation and fixation of the cooling fan 16, enabling it to accurately align with the cooling fins 14 on the other side of the electronic cooling chip 13. The overall structure is rationally laid out, and the components work together to improve the reliability and service life of the device, providing a more stable and efficient ventilation and temperature regulation environment for pig farming.
[0029] In a further preferred embodiment of the present invention, a scraper 17 is slidably installed inside the processing box 2, a drive screw 18 is rotatably installed inside the processing box 2, the drive screw 18 is threadedly connected to the scraper 17, and a drive motor 19 is fixedly installed on the processing box 2, the output shaft of the drive motor 19 is fixedly connected to the drive screw 18.
[0030] In this embodiment, when a certain amount of dirt, sediment, and other impurities accumulate on the inner wall of the treatment box 2 due to prolonged use, the drive motor 19 is activated. The output shaft of the drive motor 19 drives the drive screw 18 to rotate. According to the principle of threaded transmission, the rotation of the drive screw 18 causes the scraper 17 to move along the inner wall of the treatment box 2. As the scraper 17 moves, it contacts the inner wall of the treatment box 2, scraping away the dirt, sediment, and other impurities on the inner wall, keeping the inner wall of the treatment box 2 clean and ensuring the gas treatment effect. The drive motor model is DL112. During long-term use, dirt and sediment accumulate on the inner wall of the treatment box 2. These impurities affect the contact effect between the deodorizing liquid and the gas, reducing the gas treatment efficiency. The scraper 17 can clean the impurities on the inner wall in a timely manner, ensuring that the treatment box 2 always maintains good gas treatment capacity and effectively removes harmful gases and odors discharged from the pigsty. Traditional treatment box cleaning methods usually require manual entry into the treatment box, which is not only labor-intensive but also poses certain safety hazards. The automatic cleaning structure in this embodiment only requires starting the drive motor 19 to move the scraper 17 and perform cleaning work, which greatly reduces the workload and cost of manual maintenance and improves the operational efficiency of the farm.
[0031] In a further preferred embodiment of the present utility model, the scraper 17 is arranged in a "return" shape, and a groove is formed on one side of the scraper 17 opposite to the guide pipe 3, and the shape of the groove is adapted to the guide pipe 3.
[0032] In this embodiment, the "return" shaped scraper 17 is combined with the groove design adapted to the guide pipe 3, so that the scraper 17 can effectively clean the inner wall of the treatment tank 2 during movement, prevent collision with the part of the guide pipe 3 extending into the treatment tank 2, and ensure the smooth movement path of the scraper 17. This design of the "return" shaped scraper 17 and the groove realizes a large-scale cleaning of the inner wall of the treatment tank 2 without adding too many complex structures. The structure is simple and ingenious, with strong practicability, improves the overall performance and reliability of the device, and reduces the equipment maintenance cost of the breeding farm.
[0033] In a further preferred embodiment of the present utility model, a guide rod 20 is fixedly installed in the treatment tank 2, and the guide rod 20 slidably penetrates through the scraper 17.
[0034] In this embodiment, the arrangement of the guide rod 20 increases the stability of the movement of the scraper 17, avoids problems such as jamming and deviation of the scraper 17 during movement due to uneven force or other factors, ensures the smooth progress of the cleaning work, and improves the cleaning efficiency and effect. The stable movement of the scraper 17 can reduce the situation of cleaning interruption or incomplete cleaning caused by mechanical failures, extend the service life of the treatment tank 2 and the cleaning device, reduce the equipment maintenance cost, and improve the reliability of the entire ventilation and air exchange device. The guide rod 20 and the driving screw 18 cooperate with each other to form a complete driving and guiding system. The structure is simple and reasonable, matches the overall structure of the treatment tank 2, and does not have a negative impact on the gas treatment function of the treatment tank 2, further optimizing the overall performance of the device.
[0035] In summary, compared with related technologies, this device combines mechanical ventilation with deodorizing liquid treatment technology. Through the coordinated operation of fans and the pigsty air intake mechanism, it achieves rapid gas renewal and effective removal of harmful gases within the pigsty, significantly improving the pigsty environment and reducing the risk of respiratory diseases and other infectious diseases in pigs. The electronic cooling plates and cooling fins enable the device to automatically adjust the temperature of the fresh air entering the pigsty according to the ambient temperature, providing a more suitable growth environment for pigs, reducing stress responses caused by high temperatures, and ensuring the health and growth performance of the pigs. The cooperation between the scraper and the drive screw enables automatic cleaning of the inner wall of the treatment tank, reducing the workload and cost of manual maintenance and improving the operational efficiency of the farm. Meanwhile, the "U"-shaped scraper and guide rod design further enhances the cleaning effect and the stability of the device. The coordinated operation of all components makes the device perform excellently in ventilation, temperature regulation, cleaning, and maintenance, providing comprehensive and intelligent support for pig farming and improving farming efficiency.
