Description

Technical Field

[0001] This utility model relates to the technical field of pigsty ventilation equipment, specifically to a pigsty with a vertical ventilation system. Background Technology

[0002] To provide a better living environment for livestock and reduce the occurrence of diseases, pig farms typically install fans and evaporative cooling pads to ventilate the pigsties, increase air humidity, and expel stale air. To better control the temperature and humidity within the pigsties and ensure air circulation, evaporative cooling pads, temperature sensors, humidity sensors, and a large number of fans need to be installed throughout the pigsties. This takes up considerable space and increases costs. Even so, uneven temperatures can still occur within the pigsties, and strong drafts blowing directly on the animals can easily cause stress reactions, making them more susceptible to illness.

[0003] In addition, most pigsties currently use longitudinal ventilation, which involves installing a high-powered fan at one end of the pigsty and blowing air longitudinally to the other end. This ventilation method will have a certain degree of attenuation along the way, resulting in stronger winds and greater stress response in the animals on the side closer to the fan, while weaker winds and poor ventilation on the side farther away from the fan. Utility Model Content

[0004] The purpose of this invention is to provide a pigsty with a vertical ventilation system. The air is adjusted to a suitable temperature and humidity in the air mixing device, and then blown vertically into the pigsty through the air duct. This reduces the attenuation of the air force along the way, making the ventilation more uniform and the ventilation effect better.

[0005] This utility model includes a pigsty body, inside which several rows of breeding cages are installed from left to right. A trench ventilation duct is provided on the floor of the corridor on the side of the breeding cages, running through both ends of the pigsty body. The pigsty body also has at least one row of ventilation ducts running through both ends of the pigsty body, with the ventilation ducts located between two rows of breeding cages and spaced parallel to the breeding cages. A mixing device for supplying air into the ventilation ducts is installed on the outer front end of the pigsty body, and the mixing device has an air inlet that can draw in outside air. Several outlets are arranged at intervals on the left and right side walls of the ventilation ducts, and each outlet is equipped with a ventilation window. The airflow direction when the air blows out of the ventilation window is perpendicular to the front and rear extension direction of the pigsty body.

[0006] With the above structure, outside air enters the mixing device through the air inlet. After being treated in the mixing device, fresh air with suitable temperature and humidity is formed. The air is then discharged from the mixing device through the air outlet, and then enters the pigsty through the air duct, the outlet end, and the ventilation window. Through the ventilation window, the air is evenly distributed into the pigsty, replacing the air inside. At the same time, vertical ventilation is formed by the trench fan. The vertical airflow from top to bottom can reduce the ventilation distance and reduce dust in the pigsty. Compared with the traditional longitudinal ventilation scheme, this vertical ventilation scheme can effectively reduce the attenuation of the airflow at the rear of the pigsty and improve the overall ventilation effect.

[0007] Preferably, a pigsty ceiling is provided between two adjacent rows of air ducts or between one of the air ducts and the side wall of the main pigsty on the same side. The pigsty ceiling has an arc-shaped structure that is low on the left and right sides and high in the middle.

[0008] Preferably, several air guide plates are installed at intervals below the ceiling of the pigsty.

[0009] Preferably, the air guide plate is rotatably connected to the bottom of the pigsty ceiling.

[0010] Preferably, the air guide plate is made of two straight plates joined at a certain angle, so that it has a structure with one side being convex and the other side being concave in the direction of its cross-section, and the convex side of the air guide plate is installed facing the windward side.

[0011] Preferably, there are several air guide plates, and the length of the several air guide plates gradually increases from the edge of the pigsty ceiling to the middle of the pigsty ceiling.

[0012] Preferably, the air guide plates are installed at offset positions in the left and right directions of the pigsty.

[0013] Preferably, a spray device is installed inside the air mixing device. The spray device includes nozzles installed on the upper part of the air mixing device and a water storage tank located below the nozzles. The water storage tank is connected to a water inlet pipe. A submersible pump is installed inside the water storage tank, and the submersible pump provides circulating water to the nozzles. A hot air blower, a temperature sensor, and a humidity sensor are also installed inside the air mixing device. The submersible pump, the hot air blower, the temperature sensor, and the humidity sensor are electrically connected to a control device.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. Outside air enters the mixing device through the air inlet. After being treated in the mixing device, it forms fresh air with suitable temperature and humidity. The air is then discharged from the mixing device through the air outlet, and then enters the pigsty through the air duct, outlet, and ventilation window. With the use of ventilation windows and air guide plates, the air is evenly distributed into the pigsty, providing better ventilation. At the same time, vertical ventilation is formed by the trench fan. The vertical airflow from top to bottom can reduce the ventilation distance and reduce dust in the pigsty. Compared with the traditional longitudinal ventilation scheme, this vertical ventilation scheme can effectively reduce the attenuation of airflow at the rear of the pigsty and improve the overall ventilation effect.

[0016] 2. The main body of the pigsty is equipped with a suspended ceiling. The suspended ceiling has an arc-shaped structure that is higher in the middle and lower at both ends. Several air guide plates are installed at intervals below the suspended ceiling. The length of the air guide plates gradually increases. The air guide plate is spliced ​​together by two straight plates at a certain angle, so that its cross-section has a convex side and a concave side. The convex side of the air guide plate is installed facing the windward side. The air guide plates, together with the suspended ceiling, can evenly distribute the air to all parts of the pigsty and ensure good ventilation.

[0017] 3. After the air is adjusted to a suitable temperature and humidity in the mixing device before entering the pigsty, the temperature and humidity of the air can be better controlled, so that the air quality in various parts of the pigsty is basically consistent, reducing temperature and humidity fluctuations in the pigsty. At the same time, it can also reduce the stress response of animals. In addition, there is no need to install wet curtains, temperature sensors, humidity sensors and other equipment in the pigsty, which reduces costs and saves space. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] The orientations mentioned in this specification are based on the orientation of a pigsty with a vertical ventilation system under normal operation, and do not limit the orientation during storage and transportation. They only represent relative positional relationships and do not represent absolute positional relationships.

[0028] like Figures 1 to 3 As shown, a pigsty with a vertical ventilation system includes a main pigsty 1. Several rows of breeding cages 2 are installed inside the main pigsty 1 from left to right. A trench ventilation duct 3, running through both ends of the main pigsty 1, is located on the floor of the corridor on the side of the breeding cages 2. At least one row of ventilation ducts 5, running through both ends of the main pigsty 1, is also provided inside the main pigsty 1. The ventilation duct 5 is located between two rows of breeding cages 2 and is parallel to and spaced apart from the breeding cages 2. A mixing device 4, supplying air to the ventilation duct 5, is installed on the outer front side of the main pigsty 1. The mixing device 4 has an air inlet 20 for drawing in outside air. Several outlets are spaced at intervals on the left and right side walls, and each outlet is equipped with a ventilation window 6. The airflow direction when the air blows out of the ventilation window 6 is perpendicular to the front and back extension direction of the main body of the pigsty 1. The outside air enters the air mixing device 4 through the air inlet 20. After being treated in the air mixing device 4, it forms fresh air with a suitable temperature and humidity. It is discharged from the air mixing device 4 through the air outlet, and then enters the pigsty through the air duct 5, the outlet end, and the ventilation window 6 to replace the air in the pigsty. At the same time, it is combined with the trench fan to form vertical ventilation. The vertical airflow from top to bottom can reduce the ventilation distance and reduce dust in the pigsty.

[0029] like Figure 1 As shown, a pigsty ceiling 7 is installed between two adjacent rows of air ducts 5 or between one row of air ducts 5 and the side wall of the pigsty main body 1 on the same side. Specifically, the installation position and method of the pigsty ceiling 7 need to be determined according to the layout of the pigsty main body 1. If there are multiple rows of air ducts 5 in the pigsty main body 1, the middle part of the pigsty ceiling 7 is installed between two adjacent rows of air ducts 5, while the pigsty ceiling 7 located at the left and right ends of the pigsty main body 1 is still installed between the air ducts 5 and the side wall of the pigsty main body 1 on the same side. If the pigsty main body 1 is small and there is only one row of air ducts 5 in the middle, the pigsty ceiling 7 is installed between the air ducts 5 and the side wall of the pigsty main body 1 on the same side.

[0030] like Figure 4As shown, the pigsty ceiling 7 has an arc-shaped structure that is lower on the left and right sides and higher in the middle; several air guide plates 8 are installed at intervals below the pigsty ceiling 7; the air guide plates 8 are rotatably connected to the bottom of the pigsty ceiling 7, and a gap is left between the air guide plates 8 and the pigsty ceiling to allow air to pass through, such as... Figure 4 As shown in the figure, the arrows indicate the direction of wind speed and flow. The angle of the air guide plate 8 and the gap between the air guide plate 8 and the pigsty ceiling 7 can be adjusted according to factors such as season and ambient temperature to achieve better ventilation in the pigsty.

[0031] Preferably, such as Figure 5 As shown, the air guide plate 8 is made of two straight plates spliced ​​together at a certain angle, so that it has a structure with one side being convex and the other side being concave in the direction of its cross-section. The convex side of the air guide plate 8 is installed facing the windward side. The convex structure of the air guide plate 8 can disperse the airflow passing over its surface, so that the airflow flows to both sides of the air guide plate 8, making the wind force more evenly distributed. There are several air guide plates 8, and the length of the several air guide plates 8 gradually increases from the edge of the pig house ceiling 7 to the middle of the pig house ceiling 7, so as to reduce the wind speed attenuation at the far end of the ventilation window 6, keep the wind speed uniform, and ensure that the ventilation effect in various positions in the pig house is basically the same.

[0032] Furthermore, such as Figure 6 As shown, the air guide plates 8 are installed at staggered positions on the left and right sides of the pigsty, so that the airflow forms turbulence after entering the pigsty and spreads outwards, making the wind force more evenly distributed. At the same time, the wind force blowing on the animals is gentler, reducing the animals' stress response. The pigsty roof is arched. By adjusting the opening angle of the ventilation windows 6 on the side walls, the air is mixed with the air in the pigsty through the curvature of the roof frame and flows downwards from the middle of the pigsty. The negative pressure environment created by the trench fan at the air duct 5 allows a certain speed of orderly wind to be achieved at the slatted floor, pressing the polluted gas and dust down into the manure ditch or expelling them outside the pigsty.

[0033] like Figure 7As shown, a spraying device is installed inside the air mixing device 4. The spraying device includes a nozzle 9 installed on the upper part of the air mixing device 4 and a water storage tank 10 located below the nozzle 9. The water storage tank 10 is connected to a water inlet pipe, which replenishes water to the water storage tank 10. A submersible pump 11 is installed inside the water storage tank 10. The submersible pump 11 provides circulating water to the nozzle 9. The nozzle 9 sprays water mist into the air mixing chamber of the air mixing device 4 to increase the humidity of the air. A hot air blower 12, a temperature sensor, and a humidity sensor are also installed inside the air mixing device 4. The submersible pump 11, the hot air blower 12, the temperature sensor, and the humidity sensor are electrically connected to a control device. When the air temperature is low, the hot air blower 12 starts to heat the air. The temperature sensor and the humidity sensor collect the temperature and humidity values ​​of the air in the air mixing chamber and transmit them to the control device. The control device controls the operation of the submersible pump 11 and the hot air blower 12 according to the settings.

[0034] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
