Description

Technical Field

[0001] This utility model relates to the field of pig farming technology, and in particular to a ventilation device for pig farms that automatically regulates temperature and humidity. Background Technology

[0002] Pigs require a suitable temperature for growth. Suckling piglets need a higher temperature, generally between 25℃ and 30℃, while finishing pigs require a lower temperature, generally between 18℃ and 22℃. Temperature is a major factor affecting pig health and productivity. Within a suitable temperature range, pigs do not require heat compensation or additional heat production, resulting in the fastest weight gain and highest feed utilization. However, traditional pigsty designs are often inadequate, failing to meet the environmental requirements for normal pig growth and thus hindering pig farming.

[0003] To address the aforementioned issues, existing patent publication number CN217364154U, entitled "A Temperature and Humidity Control Device for Pigsties in Pig Farming," proposes that this utility model uses an installed temperature control switch to control the operation of a fan and heating wire, facilitating ventilation of the pigsty with hot air and temperature regulation. An installed humidity control switch controls the operation of an exhaust fan, facilitating ventilation and humidity regulation, thus ensuring comfort within the pigsty.

[0004] However, the aforementioned patents cannot physically cool or pre-heat the air entering the device during use, resulting in excessive energy consumption for cooling and heating the air, thus reducing the device's energy efficiency. Therefore, we propose an automatic temperature and humidity regulating ventilation device for pig farms to solve the aforementioned problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 An embodiment of this utility model provides an automatic temperature and humidity regulating ventilation device for pigsties, comprising a water tank 1 and a pigsty 11. Several mounting slots 12 are fixedly opened on the side of the pigsty 11. A fixed cylinder 5 is fixedly installed inside the mounting slot 12. A fan 6 and a controller are installed inside the fixed cylinder 5. A second dustproof net and a heating wire are installed on the inner wall of the fixed cylinder 5. The second dustproof net and the heating wire are both located in front of the air outlet of the fan 6, and the second dustproof net is located in front of the heating wire. A temperature and humidity detector 18 is fixedly installed at one end of the fixed cylinder 5 inside the water tank 1.

[0029] During use, the temperature and humidity detector 18 detects the temperature and humidity inside the pigsty 11. When the humidity is high, the fan 6 is turned on to promote air circulation inside the pigsty 11, remove moisture from the pigsty 11, and reduce the humidity inside the pigsty 11. When the temperature is low, the fan 6 is turned on and the heating wire is run to blow hot air into the pigsty 11, thereby ensuring that the internal environment of the pigsty 11 is maintained at a suitable temperature and humidity.

[0030] Considering that existing pigsty ventilation systems cannot physically pre-treat or heat the air entering the system, resulting in excessive energy consumption for cooling and heating, thus reducing the system's energy efficiency, this invention incorporates a heat exchange component between the fixed cylinder 5 and the water tank 1. Utilizing geothermal principles, the air entering the fixed cylinder 5 is pre-cooled in summer and pre-heated in winter, thereby maintaining the temperature inside the pigsty 11 within a reasonable range. This reduces the operating load on the electrical components inside the fixed cylinder 5 and solves the problem of excessive energy consumption and reduced energy efficiency associated with existing pigsty ventilation systems that cannot physically pre-treat or heat the air entering the system.

[0031] Specifically, the heat exchange assembly includes an air inlet pipe 3 and an air outlet pipe 4. Both the air inlet pipe 3 and the air outlet pipe 4 are covered with an insulation layer. The top of the water tank 1 is bolted with a cover 2. The air inlet pipe 3 and the air outlet pipe 4 are respectively fixed at both ends of the top of the cover 2. A first U-shaped pipe 8 is fixedly installed at one end of the air inlet pipe 3 that extends into the water tank 1. A second U-shaped pipe is fixedly installed at one end of the air outlet pipe 4 that extends into the water tank 1. The ends of the first U-shaped pipe 8 and the second U-shaped pipe are fixedly connected by a connecting pipe 10. Heat exchange plates 9 are fixedly installed on the outer ring of both the first U-shaped pipe 8 and the second U-shaped pipe. A flow collector is fixedly installed at the end of the fixed cylinder 5. The other end of the air outlet pipe 4 is fixedly connected to the end of the flow collector. The air inlet pipe 3, the first U-shaped pipe 8, the connecting pipe 10, the second U-shaped pipe, the air outlet pipe 4, the flow collector, and the air inlet end of the fan 6 are interconnected. The water tank 1 is located inside the soil layer.

[0032] After the fan 6 is started, the external air passes through the inlet pipe 3, the first U-shaped pipe 8, the connecting pipe 10, the second U-shaped pipe, the outlet pipe 4, and the collector shroud in sequence before entering the interior of the fixed cylinder 5. Through the arrangement of the first U-shaped pipe 8, the second U-shaped pipe, and the heat exchange fins 9, in summer, the air inside the pipe transfers heat to the liquid water inside the water tank 1 to cool the air inside the pipe. In winter, the heat from the liquid water inside the water tank 1 is transferred to the air inside the pipe to heat the air inside the pipe. Therefore, by utilizing the geothermal principle, the air entering the device is pre-treated for cooling or heating, reducing the energy consumption of the device.

[0033] Furthermore, the end of the air inlet pipe 3 is threadedly connected to a threaded cylinder 13, and a filter cylinder 7 is fixedly installed at the end of the threaded cylinder 13. The inner wall of the filter cylinder 7 is sequentially provided with a first dustproof net 14, filter cotton and activated carbon plate along the wind direction. The first dustproof net 14, filter cotton and activated carbon plate are used to filter the air entering the fixed cylinder 5 to ensure the air quality entering the pig house 11. When it is necessary to clean the inside of the filter cylinder 7, the threaded cylinder 13 can be unscrewed, which improves the convenience of the device.

[0034] Furthermore, a water pump is fixedly installed in the middle of the bottom of the tank cover 2. The water outlet end of the water pump is connected to a water outlet pipe 15, and the water inlet end of the water pump is connected to a water inlet pipe. The other end of the water outlet pipe 15 passes through the tank cover 2 and is fixedly connected to the fixed cylinder 5. A diversion pipe 16 is fixedly installed at the end of the fixed cylinder 5 through a connecting rod. Several nozzles 17 are fixedly installed on the inner wall of the diversion pipe 16 in a ring-shaped and uniform arrangement. The water outlet pipe 15 passes through the fixed cylinder 5 and is fixedly connected to the diversion pipe 16. A water supply pipe is installed on the top of the tank cover 2, and a pipe cap is threadedly connected to the top of the water supply pipe.

[0035] When it is necessary to increase the humidity inside the pigsty 11, the water pump is started to draw water out of the water tank 1 and spray it out through the nozzle 17. Under the action of the fan 6, the water is evenly diffused inside the pigsty 11, which facilitates the increase of humidity inside the pigsty 11.

[0036] Furthermore, the fan 6, water pump, and temperature and humidity detector 18 are all electrically connected to the controller. The wiring diagram of the fan 6, water pump, temperature and humidity detector 18 and controller in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. The control method and wiring layout will not be explained in detail.

[0037] Working principle: During use, after the fan 6 is started, the external air passes through the air inlet pipe 3, the first U-shaped pipe 8, the connecting pipe 10, the second U-shaped pipe, the air outlet pipe 4, and the collector shroud in sequence before entering the interior of the fixed cylinder 5. Through the arrangement of the first U-shaped pipe 8, the second U-shaped pipe, and the heat exchange fins 9, in summer, the air inside the pipe transfers heat to the liquid water inside the water tank 1 to cool the air inside the pipe. In winter, the heat from the liquid water inside the water tank 1 is transferred to the air inside the pipe to heat the air inside the pipe. Therefore, by utilizing the geothermal principle, the air entering the device is pre-treated for cooling or heating, reducing the energy consumption of the device.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
