Description

Technical Field

[0001] This application relates to the technical field of livestock breeding, and particularly to a ventilation system for breeding environment. Background Art

[0002] As the name implies, building breeding means raising pigs in buildings. By using the three-dimensional breeding mode, more pigs can be raised per unit area. At the same time, according to the types of pig groups, they are raised in separate buildings, which can maximize the all-in and all-out of pigs and save labor. According to different feeding purposes, it can be divided into breeding pig houses, gestation pig houses, farrowing pig houses, growing pig houses and fattening pig houses, etc. Feeding and drinking water are generally carried out inside the houses, and the pig houses are usually equipped with ventilation systems for the circulation of air inside and outside the houses.

[0003] In the breeding environment of pig houses, temperature and air flow are important factors affecting animal thermal comfort and breeding economic benefits. At present, the breeding environment temperature of commercial pigs is more suitable between 21 and 23 degrees Celsius.

[0004] In the prior art, the heat preservation effect of the ventilation system for building breeding is poor. Most of them directly exchange the outside normal temperature air with the air inside the main body of the building pig house, and cannot cool the temperature inside the pig house well, resulting in a higher environmental temperature in the pig house and affecting the growth of piglets. Therefore, it needs to be improved. Summary of the Utility Model

[0005] In order to improve the breeding environment of pig houses, this application provides a ventilation system for breeding environment.

[0006] The ventilation system for breeding environment provided by this application adopts the following technical solutions:

[0007] A ventilation system for breeding environment includes a building main body, a fan, a water curtain paper and a heat preservation pad. The building main body is used for breeding piglets. An air inlet is opened on the building main body, and the air inlet is used for external air to enter the building main body; the water curtain paper is arranged on the side where the air inlet is located; an air outlet is also opened on the building main body, and the air outlet is used for the air inside the building main body to flow out; the heat preservation pad is arranged on the outer peripheral side of the building main body, and the heat preservation pad is made of heat-insulating materials.

[0008] By adopting the above technical solutions, piglets are bred in the building main body. The fan inhales external air from the air inlet and makes the air pass through the water curtain paper at a certain speed (the wind speed is between 1.8 meters and 2.2 meters per second). The heat can be taken away by water evaporation, so that the air passing through the water curtain is cooled. The cooled air enters the building main body, and the air with a higher temperature inside the building main body is discharged from the air outlet, thus forming the replacement of hot and cold air, and effectively maintaining the temperature inside the building main body between 21 and 23 degrees Celsius.

[0009] Meanwhile, the presence of the heat preservation pad can create a sealed condition with good heat preservation and insulation for the main building of the pigsty, reduce the heat transfer between the main building of the pigsty and the external environment, and effectively maintain the constancy of the temperature inside the main building of the pigsty.

[0010] Preferably, a number of dormitory units, unit pig driving channels and production channels are provided inside the main building of the pigsty. The dormitory units are arranged at intervals in the length, width and height directions of the main building of the pigsty. The unit pig driving channels are arranged between two adjacent dormitory units, and each unit pig driving channel communicates with the production channel; the two ends of the production channel are respectively a personnel entrance and exit and a pig loading platform.

[0011] By adopting the above technical solution, each dormitory unit can be used as a place for piglet breeding. When piglets need to be slaughtered and processed, the staff can enter from the personnel entrance and exit, then drive the piglets in the dormitory unit to the unit pig driving channel, and then further drive them to the production channel, and finally reach the pig loading platform.

[0012] Preferably, an air filtration device is further included. The air filtration device and the water curtain paper are arranged in sequence along the air flow direction. The air filtration device is used to filter the air blown in by the fan.

[0013] By adopting the above technical solution, since the external air generally contains impurities, by adding a primary or sub-high efficiency air filtration device, the dust and fine particles in the air can be blocked in front of the device, reducing the impact of dust impurities on breeding.

[0014] Preferably, a cooling device is further included. The cooling device is used to further cool the air cooled by the water curtain paper.

[0015] By adopting the above technical solution, the cooling device can further significantly reduce the air temperature on the basis of the cooling of the water curtain paper, so as to achieve the intervention intensity for the control of the entire environment during the production process.

[0016] Preferably, the air supply channel of the cooling device is in a flared shape, and air enters from the opening at the larger diameter end and flows out from the opening at the smaller diameter end.

[0017] By adopting the above technical solution, the cooling device adopts the physical principle of compressed air cooling, allowing air to pass through the flared channel (entering from the larger diameter opening and flowing out from the smaller diameter opening) at a relatively fast speed. During this process, the air is compressed and energy is released, causing the air temperature to drop.

[0018] Preferably, an adsorption layer is further provided at the output end of the air filtration device. The adsorption layer is made of fiber material.

[0019] By adopting the above technical solution, based on the fiber adsorption principle, the fiber material has both ventilation and good adsorption properties. Allowing air to pass through the fiber material at a certain speed enables fine particles such as dust in the air to adhere to the fiber material, thereby making the air cleaner after passing through. Moreover, the vast majority of germs are attached to fine particles such as dust, which can also effectively isolate germs and provide great assistance to pig breeding production.

[0020] Preferably, the main building of the pigsty is a reinforced concrete structure building.

[0021] By adopting the above technical solution, this ventilation system produces better effects under the conditions that the pigsty is relatively airtight and has good heat insulation. In this way, the negative pressure effect generated when the fan works is good, the air circulation path is relatively single, and the circulation is smooth. Using a reinforced concrete structure building can well ensure the airtightness inside the main building of the pigsty and reduce the impact on the temperature of the breeding environment.

[0022] Preferably, it further includes an alarm system, and the alarm system is for power-off alarm, carbon dioxide and ammonia over-standard alarm.

[0023] By adopting the above technical solution, when the alarm system detects abnormal situations inside the main building of the pigsty, it can promptly issue corresponding alarms so that the staff can make timely responses to achieve safe production.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] (1) By setting up a fan and a water curtain paper, the fan sucks external air from the air inlet and makes the air pass through the water curtain paper at a certain speed. Utilizing the fact that water evaporation can take away heat, the temperature of the air passing through the water curtain is reduced, effectively maintaining the temperature inside the main building of the pigsty between 21 and 23 degrees Celsius.

[0026] (2) By setting up an air filtration device, the air filtration device can block dust and fine particles in the air at the front end of the device, reducing the impact of dust impurities on breeding.

[0027] (3) By setting up an alarm system, when the alarm system detects abnormal situations inside the main building of the pigsty, it can promptly issue corresponding alarms so that the staff can make timely responses. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The embodiments of the present application disclose a ventilation system for a breeding environment. Refer toFigures 1 to 3 , the ventilation system includes the building main body 1, the fan 2, the water curtain paper 3 and the thermal insulation pad 4. The building main body 1 serves as a place for piglet breeding. In this embodiment, the building main body 1 is a reinforced concrete structure building. Specifically, several dormitory units 5, unit pig driving passages 6 and production passages 7 are provided in the building main body 1. The dormitory units 5 are arranged at intervals in the length, width and height directions of the building main body 1, and each dormitory unit 5 is used for piglet breeding. The unit pig driving passage 6 is arranged between two adjacent dormitory units 5 and is used for piglets to pass through. The production passage 7 is located in the middle area of the building main body 1, and each unit pig driving passage 6 is connected to the production passage 7. The two ends of the production passage 7 are respectively a personnel entrance and exit 8 and a pig loading platform 9. The personnel entrance and exit 8 is for personnel to pass through, and the pig loading platform 9 serves as a platform for slaughtering and feeding piglets. When piglets need to be slaughtered and processed, the staff can enter from the personnel entrance and exit 8, then drive the piglets in the dormitory unit 5 to the unit pig driving passage 6, and then further drive them to the production passage 7, and finally reach the pig loading platform 9.

[0039] An air inlet 10 is opened on the building main body 1, and the air inlet 10 is used for external air to enter the building main body 1. The water curtain paper 3 is installed on the side where the air inlet 10 is located. An air outlet 11 is also opened on the building main body 1, and the air outlet 11 is used for the air in the building main body 1 to flow out. The thermal insulation pad 4 is fixedly installed on the outer peripheral side of the building main body 1. The thermal insulation pad 4 is made of heat-insulating material and is used for heat preservation of the building main body 1.

[0040] During the breeding process, the fan 2 sucks external air from the air inlet 10 and makes the air pass through the water curtain paper 3 at a certain speed (the wind speed is between 1.8 meters and 2.2 meters per second). Since water evaporation can take away heat, the air passing through the water curtain is cooled. The cooled air enters the building main body 1, and the air with a higher temperature in the building main body 1 is discharged from the air outlet, thus forming a replacement of cold and hot air, so that the temperature in the building main body 1 is effectively maintained between 21 and 23 degrees Celsius.

[0041] At the same time, the existence of the thermal insulation pad 4 can create a closed and well heat-insulated condition for the building main body 1, reduce the heat transfer between the building main body 1 and the external environment, effectively maintain the constancy of the temperature in the building main body 1, and create a good temperature environment for the growth of piglets.

[0042] Among them, an air filtration device 12 is also installed in the main building 1. The air filtration device 12 and the water curtain paper 3 are arranged in sequence along the air flow direction. The air filtration device 12 is used to filter the air blown in by the fan 2. Since the external air generally contains impurities, by adding a primary or sub-high efficiency air filtration device 12, the dust and fine particles in the air can be blocked at the front end of the device, reducing the impact of dust impurities on breeding. Among them, in some embodiments, an adsorption layer is further provided at the output end of the air filtration device 12. The adsorption layer is made of fiber material. The fiber material has both air permeability and good adsorption. By adopting the fiber adsorption principle and allowing the air to pass through the fiber material at a certain speed, the dust and other fine particles in the air can be attached to the fiber material, making the air cleaner after passing through. Moreover, most of the germs are attached to the dust and other fine particles, so it can also effectively isolate the germs, providing great help for pig breeding production.

[0043] In addition, in combination with Figure 4 , a cooling device 13 is also installed in the main building 1. The cooling device 13 is used to further cool the air cooled by the water curtain paper 3. In this embodiment, the air supply channel of the cooling device 13 is in a flared shape. The air enters from the opening with a larger diameter and flows out from the opening with a smaller diameter. The cooling device 13 adopts the principle of compressed air cooling in physics. Let the air pass through the flared channel (enter from the opening with a larger diameter and flow out from the opening with a smaller diameter) at a faster speed. During this process, the air is compressed and releases energy, causing the air temperature to drop. On the basis of the cooling of the water curtain paper 3, the cooling device 13 further significantly reduces the air temperature, thereby achieving a strong intervention in the control of the entire environment during the production process.

[0044] In some embodiments, an alarm system (not shown in the figure) is also provided in the main building 1. The alarm system can be, but is not limited to, power failure alarm, carbon dioxide over-standard alarm, and ammonia over-standard alarm. When the alarm system detects an abnormal situation in the main building 1, it can promptly issue corresponding alarms so that the staff can respond in a timely manner to achieve safe production.

[0045] The implementation principle of a ventilation system for a breeding environment in an embodiment of the present application is as follows: Piglets are bred in the main building 1. The fan 2 guides the air from the outside to the inside. The primary or sub-high efficiency air filtration device 12 blocks the dust and fine particles in the air at the front end of the device, and the air completes the purification process. Then the air passes through the water curtain paper 3 at a certain speed (the wind speed is between 1.8 m and 2.2 m / s). Using the fact that water evaporation can take away heat, the air passing through the water curtain is cooled.

[0046] Subsequently, the cooled air enters the flared cooling device 13, and the air temperature is reduced again and enters the main building 1 of the pigsty. The hot air in the main building 1 of the pigsty is discharged from the air outlet, thus forming a replacement of hot and cold air, effectively maintaining the temperature in the main building 1 of the pigsty between 21 and 23 degrees Celsius.

[0047] The presence of the heat preservation pad 4 can create a closed condition with good heat preservation and insulation for the main building 1 of the pigsty, reduce the heat transfer between the main building 1 of the pigsty and the external environment, effectively maintain the constancy of the temperature in the main building 1 of the pigsty, and ensure the normal growth of piglets.

[0048] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
