Abstract
Description
Technical Field
[0001] This utility model relates to the field of poultry house structure technology, and in particular to a poultry house ventilation structure and poultry house. Background Technology
[0002] Poultry houses are buildings specifically constructed for raising poultry (such as chickens, ducks, geese, etc.). Their design and construction need to take into account multiple aspects such as the growth needs, health, management, and production efficiency of poultry. Poultry house ventilation is an important part of the poultry house design process. Poultry house ventilation can provide fresh air for poultry and regulate the internal temperature of the poultry house, thereby reducing the occurrence of poultry diseases and increasing profits.
[0003] Currently, when small-volume ventilation is required in poultry houses, air is usually introduced through small windows. When the negative pressure fan on the back wall is turned on, negative pressure is created inside the house, and fresh air enters the house through the small windows and flows into the cages, thus achieving ventilation for the poultry.
[0004] However, if there is a large temperature difference between the inside and outside of the shed in the north or during winter, cold air will enter the shed and flow directly into the cages of poultry, which will inevitably cause cold stress to the poultry, causing them to get sick and bringing serious consequences to the breeding. Utility Model Content
[0005] This application provides a poultry house ventilation structure that reduces cold stress in poultry caused by temperature differences between the inside and outside of the house, thereby reducing disease incidence and improving poultry farming performance. This application also provides a poultry house employing the aforementioned ventilation structure.
[0006] The first aspect of this application provides a poultry house ventilation structure, including:
[0007] A partition is installed in the poultry house and above the breeding cages. The partition has air vents located above the area between the breeding cages. A heat exchange zone is formed between the partition and the roof of the poultry house.
[0008] A ventilation component is installed at the air inlet of the poultry house, the air inlet being located above the partition, and the ventilation component is used to control the opening and closing of the air inlet;
[0009] The first exhaust ventilation system is located above the partition and connected to the poultry house.
[0010] The second exhaust system is located below the partition and connected to the poultry house.
[0011] The beneficial effects of the above embodiments are as follows: by forming a double-layer roof structure with the partition and the roof, the first exhaust mechanism draws the hot air in the breeding area to the heat exchange area to exchange heat with the cold air entering from outside the poultry house, realizing the reuse of waste heat in the poultry house. After the cold air is heated, it is drawn into the area between the breeding cages by the second fan for diffusion, avoiding the cold air from flowing directly to the poultry after entering the house, reducing the cold stress of the poultry due to temperature difference, reducing the occurrence of diseases, and thus improving breeding performance.
[0012] Based on the above embodiments, the embodiments of this application can be further improved as follows:
[0013] In one embodiment of this application: the partition is provided with a guide surface corresponding to the air inlet, the guide surface being used to guide the cold air entering from outside the building obliquely upwards. The beneficial effect of this step is that it allows the cold air entering the heat exchange zone to fully mix with the hot air inside the building.
[0014] In one embodiment of this application, the guide surface is a smooth surface. The beneficial effect of this step is that it can reduce wind resistance and improve heat exchange efficiency.
[0015] In one embodiment of this application, the roof is a gable-shaped or convex arc-shaped structure. The beneficial effect of this step is that it increases the height space in the middle of the heat exchange zone, allowing for more thorough mixing and heat exchange of hot and cold air.
[0016] In one embodiment of this application, the inner wall of the roof is a smooth surface. The beneficial effect of this step is that it can reduce wind resistance and improve heat exchange efficiency.
[0017] In one embodiment of this application, it further includes a temperature sensor connected to the poultry house for detecting the outside temperature. The temperature sensor is electrically connected to the ventilation components, the first exhaust mechanism, and the second exhaust mechanism. The beneficial effect of this step is that the ventilation components, the first exhaust mechanism, and the second exhaust mechanism work together to achieve the function of air exchange after heat exchange, thereby improving automation and reducing labor costs.
[0018] The second aspect of this application provides a poultry house, including the aforementioned poultry house ventilation structure. Attached Figure Description

[0026] Example 1
[0027] like Figure 1 , 2 As shown, a poultry house ventilation structure includes: a partition 1, a ventilation component 2, a first exhaust mechanism 3, and a second exhaust mechanism 4. The partition 1 is disposed in the poultry house and located above the breeding cages. The partition 1 has air holes 101 located above the area between the breeding cages. A heat exchange zone 5 is formed between the partition 1 and the roof of the poultry house. The ventilation component 2 is disposed at an air inlet 6 opened in the poultry house. The air inlet 6 is located above the partition 1 and is used to control the opening and closing of the air inlet 6. The first exhaust mechanism 3 is disposed above the partition 1 and connected to the poultry house. The second exhaust mechanism 4 is disposed below the partition 1 and connected to the poultry house.
[0028] Specifically, such as Figure 1 As shown, partition 1 and the roof form a double-layer roof structure. Partition 1 forms a suspended ceiling structure inside the house. Air inlets 6 are opened sequentially at intervals along the side walls of the poultry house. Air inlets 6 are located above partition 1. Ventilation components 2 adopt small ventilation windows. The small ventilation windows are installed at the ventilation openings and are used to control the flow of air in and out of the ventilation openings.
[0029] Specifically, such as Figure 1 As shown, the partition 1 is equipped with a guide surface 102 corresponding to the air inlet 6. The guide surface 102 is used to guide the cold air entering from outside the building to flow obliquely upward. In the direction towards the middle of the heat exchange zone 5, the guide surface 102 is an upward sloping surface. After the cold air enters the building through the guide surface 102, it moves upward, so that the cold air and the hot air inside the building are more fully mixed.
[0030] Specifically, the guide surface 102 is a smooth surface, which helps to reduce wind resistance and improve heat exchange efficiency.
[0031] Specifically, such as Figure 1 As shown, the roof has a gable or convex arch structure, which increases the height space in the middle of the heat exchange zone 5, allowing the hot and cold air to mix and exchange heat fully.
[0032] Specifically, the inner wall of the roof is smooth, which helps to reduce wind resistance and improve heat exchange efficiency.
[0033] Specifically, such as Figure 1 As shown, the first exhaust mechanism 3 and the second exhaust mechanism 4 are negative pressure fans, which are installed on the rear wall.
[0034] The working process of this poultry house ventilation structure is as follows: When it is necessary for cold air from outside to enter the house for ventilation, the air inlet 6 is first closed through the ventilation component 2, the first exhaust mechanism 3 is opened, and the hot air in the breeding area is drawn into the heat exchange zone 5. The first exhaust mechanism 3 is then closed, the ventilation component 2 is opened, and the second exhaust mechanism 4 is started. A negative pressure is formed in the breeding area, which causes the cold air from outside to first enter the heat exchange zone 5 and mix with the hot air therein to increase its temperature. Then, they enter the passageway of the breeding area through the air hole 101 and diffuse toward the breeding cages on both sides. Therefore, it can prevent the cold air from outside from blowing directly into the breeding cages, thereby reducing the poultry's emergency response to temperature differences, reducing the occurrence of diseases, and thus improving breeding performance.
[0035] Example 2
[0036] The difference between Embodiment 2 and Embodiment 1 is that the poultry house ventilation structure further includes: a temperature sensor connected to the outside of the poultry house, used to detect the outside temperature, and the temperature sensor is electrically connected to the ventilation component 2, the first exhaust mechanism 3, and the second exhaust mechanism 4.
[0037] Specifically, the poultry house ventilation structure also includes a controller, a temperature sensor connected to the controller's electrical control signal, and the controller connected to the ventilation component 2, the first exhaust mechanism 3, and the second exhaust mechanism 4's electrical control signal. The ventilation component 2 uses an electric window, and the controller uses a PLC controller, industrial computer, or industrial computer, etc.
[0038] The specific working process is as follows: a temperature sensor detects the outside temperature. When the temperature is lower than the preset value, the temperature sensor sends a signal to the controller. The controller then controls the ventilation component 2 to close the air inlet 6 and starts the first exhaust mechanism 3. After the first exhaust mechanism 3 runs for a period of time, it is then closed. Next, the ventilation component 2 is controlled to open the air inlet 6 and start the second exhaust mechanism 4. The second exhaust mechanism 4 draws the cold air into the heat exchange zone 5 for heat exchange before it enters the breeding area. Therefore, through the cooperation of the ventilation component 2, the first exhaust mechanism 3, and the second exhaust mechanism 4, automated ventilation can be achieved.
