Description

Technical Field

[0001] This utility model relates to the field of poultry farming equipment technology, and in particular to a ventilation structure and poultry house for poultry farming environment. Background Technology

[0002] In poultry farming, small windows are commonly used as the main air intakes for low-volume ventilation in poultry houses. When the negative pressure fan on the back wall is activated, a negative pressure environment is quickly created inside the poultry house, drawing in fresh outside air through the small windows. This fresh air circulates naturally within the poultry house, achieving ventilation and ensuring the normal life activities of the poultry.

[0003] However, this ventilation method can cause problems under certain conditions. Especially in the cold season in the north, where the temperature difference between inside and outside the shed is large, cold air entering through small windows, if not preheated or buffered, will directly contact the poultry, causing cold stress. This can lead to physiological dysfunction, illness, and decreased immunity, threatening the poultry's health. Furthermore, in multi-layer cage rearing systems, when the number of layers exceeds four, ventilation efficiency becomes a significant issue. Fresh air struggles to penetrate the lower cages, affecting the respiration and metabolism of the lower-level poultry. It also hinders heat dissipation and the removal of stale air, which, in the long run, will be detrimental to poultry growth, reducing breeding efficiency and economic benefits. Utility Model Content

[0004] This application provides a ventilation structure for poultry farming environments to address the problem of cold stress in poultry caused by direct ventilation in winter, and also solves the industry-wide problems of large temperature differences and poor air uniformity in multi-story farming. This application also provides a poultry house employing the aforementioned ventilation structure for poultry farming environments.

[0005] The first aspect of this application provides a ventilation structure for a poultry farming environment, comprising:

[0006] The building is equipped with a first air vent, a second air vent, and a third air vent.

[0007] A suspended ceiling is connected to the enclosure. The first and second ventilation ports are located above the suspended ceiling, and the third ventilation port is located below the suspended ceiling. The area above the suspended ceiling forms a heat exchange zone, and the area below forms a breeding zone. The suspended ceiling is also provided with ventilation holes that connect the heat exchange zone and the breeding zone.

[0008] The air duct connects the second air exchange port to the third air exchange port.

[0009] The beneficial effects of the above embodiment are as follows: Fresh air from outside the poultry house is introduced into the heat exchange zone through the first ventilation port for heat exchange. The cold air mixes with the hot air in the heat exchange zone and heats up. Part of the warm air after heat exchange enters the space above the breeding area directly through the ventilation hole, and the other part enters the space below the breeding area through the air duct. This design structure can effectively prevent cold air from blowing directly onto the poultry, and can solve the technical problem of poor ventilation in the area below the multi-layer breeding cages, thereby achieving temperature and air quality consistency in the vertical direction.

[0010] Based on the above embodiments, the embodiments of this application can be further improved as follows:

[0011] In one embodiment of this application, it further includes a first fan connected to the air duct, the first fan being used to control the flow direction of gas in the air duct. The beneficial effect of this step is that the first fan can discharge air from the bottom of the enclosure to the heat exchange zone for heat exchange, and can also control the flow of warm air after heat exchange to the bottom of the enclosure, thereby improving ventilation efficiency and effectiveness.

[0012] In one embodiment of this application, it further includes a ventilation window connected to the first air exchange port. The beneficial effect of this step is that the ventilation window controls the communication between the inside and outside of the building.

[0013] In one embodiment of this application: the ceiling has a guiding surface, which is adjacent to the first and second air vents, and is used to guide gas to flow upwards towards the center of the heat exchange zone. The beneficial effect of this step is that by guiding the gas flow through the guiding surface, the gas flow distance is increased, allowing for sufficient heat exchange between the gases.

[0014] In one embodiment of this application, the ventilation hole faces the aisle between the poultry cages. The beneficial effect of this step is that it prevents fresh air from blowing directly onto the poultry, thereby further reducing the probability of cold stress.

[0015] In one embodiment of this application, it further includes a second fan connected to the breeding area. The beneficial effect of this step is that the second fan generates negative pressure in the breeding area, drawing warm air from the heat exchange zone into the breeding area, thereby accelerating ventilation efficiency.

[0016] In one embodiment of this application, it further includes a third fan connected to the heat exchange zone. The beneficial effect of this step is that by controlling the order in which the second and third fans are turned on, the function of first drawing hot air from the feeding area into the heat exchange zone, and then drawing fresh air that has undergone heat exchange from the heat exchange zone back into the feeding area is achieved.

[0017] A second aspect of this application provides a poultry house, including the aforementioned ventilation structure. Attached Figure Description

[0025] Example 1

[0026] A ventilation structure for a poultry farming environment includes: a housing 1, a ceiling 2, and an air duct 3. The housing 1 is equipped with a first air vent 101, a second air vent 102, and a third air vent 103. The ceiling 2 is connected to the housing 1. The first air vent 101 and the second air vent 102 are located above the ceiling 2, and the third air vent 103 is located below the ceiling 2. The area above the ceiling 2 forms a heat exchange zone 104, and the area below forms a farming zone 105. The ceiling 2 also has ventilation holes 201 that connect the heat exchange zone 104 and the farming zone 105. The air duct 3 connects the second air vent 102 and the third air vent 103.

[0027] Specifically, the enclosure 1 includes a roof, side walls, a front gable wall, and a rear gable wall. The side walls are located on both sides of the front gable wall and the rear gable wall. The roof is located above the side walls, the front gable wall, and the rear gable wall. The ceiling 2 is a flat structure and is connected between the side walls, the front gable wall, and the rear gable wall. The breeding area 105 below the ceiling 2 contains breeding cages arranged in multiple rows, with passageways between adjacent rows of breeding cages.

[0028] Specifically, the ventilation structure also includes a first fan 4, which is connected to the third ventilation port 103. The first fan 4 is used to control the flow direction of gas in the air duct 3. The first fan 4 can exhaust the air at the bottom of the housing 1 to the heat exchange zone 104 for heat exchange, and can also control the warm air that has completed heat exchange to flow back to the bottom of the housing 1, thereby improving the ventilation efficiency and effect.

[0029] Specifically, the ventilation structure also includes a ventilation window 5, which is connected to the first ventilation port 101. The ventilation window 5 is a commonly used product in poultry houses, and it controls the connection between the inside and outside of the house.

[0030] Specifically, the ceiling 2 has a guide surface 202, which is adjacent to the first air exchange port 101 and the second air exchange port 102. The guide surface 202 is used to guide the gas to flow upward toward the center of the heat exchange zone 104. In the direction toward the center of the heat exchange zone 104, the guide surface 202 is an inclined surface arranged at the edge of the ceiling 2 and tilted upward. When outside air enters the heat exchange zone 104 through the first air exchange port 101, it comes into contact with the guide surface 202, and the guide surface 202 guides the air to move upward, increasing the distance that fresh air travels in the second heat exchange zone, so that the hot and cold air can exchange heat fully.

[0031] Specifically, ventilation vent 201 is positioned directly opposite the aisle between the cages. This prevents fresh air from blowing directly onto the poultry, thereby further reducing the probability of cold stress.

[0032] Specifically, the ventilation structure also includes a second fan 6, which is connected to the breeding area 105. There are multiple second fans 6 installed on the rear wall. The second fans 6 draw air out of the shed, thereby creating negative pressure in the breeding area and drawing warm air from the heat exchange zone 104 into the breeding area, thus accelerating the ventilation efficiency.

[0033] Specifically, the ventilation structure also includes a third fan 7, which is connected to the heat exchange zone 104. There are multiple third fans 7, which are installed on the rear wall. By controlling the order in which the second fan 6 and the third fan 7 are turned on, the function of first drawing hot air from the feeding area into the heat exchange zone 104, and then drawing fresh air that has completed heat exchange from the heat exchange zone 104 into the feeding area is realized.

[0034] When this ventilation structure is in use, there are first fans 4, second fans 6, and third fans 7. The opening sequence and forward / reverse direction of the first fans 4, second fans 6, and third fans 7 can be adjusted, so there are multiple ventilation control methods. However, this does not affect the implementation of the structure, and the control methods are not within the scope of protection of this application. Therefore, the following is an example of one control method: First, turn on the first fans 4 and the third fans 7 to draw the hot air in the breeding area 105 into the heat exchange area 104. Then, turn off the fans, open the ventilation window 5, and fresh outside air enters the heat exchange area 104 to mix and exchange heat with the hot air in the heat exchange area 104. Then, turn on the third fans 7 and turn the first fans 4 in reverse to draw the heat-exchanged fresh air into the upper layer of the breeding area through the vent 201 and into the lower layer of the breeding area through the air duct 3, thereby achieving all-round ventilation.

[0035] Therefore, this ventilation structure, through its double-layered roof, effectively preheats the fresh air entering the poultry house during cold seasons, preventing cold air from directly contacting the poultry and significantly reducing the probability of cold stress, thus protecting the poultry's health. Simultaneously, addressing the industry challenge of large temperature differences and poor air uniformity in multi-layered poultry farming, this ventilation structure employs a unique airflow mechanism. By simultaneously supplying air to both upper and lower layers, it ensures that fresh air is evenly distributed to each cage, effectively reducing the temperature difference between layers and improving the overall air uniformity of the farming environment. This design not only improves the poultry's living environment but also promotes effective air circulation within the house, contributing to increased farming efficiency and economic benefits.
