Description

Technical Field

[0001] This utility model relates to the field of poultry farming building technology, and in particular to a ventilation structure for optimizing the microenvironment of chicken houses. Background Technology

[0002] Improper ventilation in chicken houses is a major factor contributing to chicken diseases. Lateral ventilation in chicken houses is widely used because the air velocity during ventilation is below 0.1 m / s, which is considered windless ventilation. However, the lack of necessary control over the exhaust of polluted air leads to secondary pollution and environmental damage in the chicken farm's microenvironment, thus affecting the farm's long-term stable production performance. Furthermore, in northern winters, chicken houses require not only ventilation but also insulation, further increasing the difficulty of ventilation. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes an optimized ventilation structure for chicken coops. The purpose of this ventilation structure is to control the location of polluted air discharge, prevent secondary air pollution, and maximize the temperature of the air entering the chicken coop during winter.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An optimized ventilation structure for a small-scale chicken coop includes an exhaust structure comprising a horizontal exhaust channel and a vertical exhaust channel. An air inlet side window is provided at the top of the outer wall of the chicken coop, and a fan is installed at the bottom of the outer wall of the chicken coop near the ground. The first end of the horizontal exhaust duct connects to the fan on the outer wall of the chicken house, the lower end of the vertical exhaust duct connects to the second end of the horizontal exhaust duct, and the top of the vertical exhaust duct is higher than the roof of the chicken house.

[0005] Preferably, the top of the vertical exhaust duct is connected to a top plate by a bracket, and the top plate and the upper bracket of the vertical exhaust duct form an exhaust port.

[0006] Preferably, the air inlet side window is provided with a baffle that can close the air inlet side window.

[0007] Preferably, the side wall of the transverse exhaust duct is provided with an access door for workers to enter the transverse exhaust duct.

[0008] Preferably, a guide plate for guiding the gas flow is provided at the connection between the horizontal exhaust channel and the vertical exhaust channel.

[0009] Preferably, the ventilation structure of the optimized small-environment chicken house also includes a return air structure, which includes a return air duct, a heat exchange duct, and an inner duct. The return air duct passes through the side wall of the vertical exhaust channel. The front end of the heat exchange duct is connected to the return air duct, and the return air duct extends inside the horizontal and vertical exhaust channels. The end of the heat exchange duct is connected to the inner duct, which is installed inside the chicken house.

[0010] Preferably, the inner pipe is a pipe that extends vertically along the inner side of the outer wall of the chicken house.

[0011] Preferably, the end of the inner tube is connected to a horizontal tube, which extends perpendicularly to the outer wall of the chicken coop in a direction away from the outer wall. Preferably, there are multiple sets of exhaust and return air structures, and the ends of multiple return air structures are connected to a heat exchanger pipe, which is densely covered with through holes.

[0012] The beneficial effects of using this utility model are: This ventilation structure, with its elevated vertical exhaust ducts, allows exhaust air from the chicken coop to be quickly carried away by the high-level airflow, preventing polluted air from circulating back into the coop. This design also avoids the possibility of polluted air entering through the intake windows of the other coop when two coops are facing each other, thus preventing the spread of disease and the potential for contamination.

[0013] In addition, to meet the heat exchange needs of chicken houses in winter, the return air structure can exchange heat with the high-temperature air exhausted from the chicken house during the process of bringing ambient air into the chicken house, thus preventing the chickens from being exposed to sudden cold air.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0020] Example 1

[0021] like Figure 1 As shown, the optimized ventilation structure of the chicken coop in this embodiment has a horizontally placed air inlet window 11 on the outer wall 10 near the ceiling, and a square channel below the outer wall 10 near the ground. A fan 13 is installed in this channel to guide the stale air inside the chicken coop outwards. An exhaust structure 20 is installed at the position corresponding to the fan 13. The first end of the horizontal exhaust channel 21 is connected to the position of the fan 13 on the outer wall 10, and the lower end of the vertical exhaust channel 22 is connected to the second end of the horizontal exhaust channel 21. The vertical exhaust channel 22 is erected vertically, and its top is higher than the ceiling of the chicken coop.

[0022] When ventilation is needed in the chicken coop, the air inlet side window 11 is opened. Outside air enters the coop from a higher position through the air inlet side window 11, preventing debris and pollutants from entering the coop with the airflow. The stale air inside the coop, due to its higher temperature, is exhausted outside through the horizontal exhaust duct 21 and the vertical exhaust duct 22. Because the exhaust vent 24 of the exhaust structure 20 is positioned high, the airflow is rapid, creating a chimney effect. If ventilation efficiency is insufficient, the fan 13 can be actively turned on to provide air pressure and force the stale air out of the coop.

[0023] In one feasible embodiment, the horizontal exhaust duct 21 is made of corrugated board with a length of 180cm, a width of 130cm, and a height of 170cm, with an internal metal frame to prevent the corrugated board from deforming. Its front end is connected to the exhaust side of the fan 13, and its rear end is connected to the vertical exhaust duct 22 and sealed.

[0024] The vertical exhaust duct 22 has a bottom structure that is 100cm long, 130cm wide, and 810cm high. The bottom inner side connects with the horizontal exhaust duct 21, and the top retains a 50cm four-sided exhaust port 24. The four sides are made of corrugated board, and the surrounding gaps are sealed.

[0025] The top plate 23 is located above the vertical exhaust duct 22 and is spaced apart from the upper end of the vertical exhaust duct 22 by a metal bracket. The top plate 23 serves to shelter from rain. Its area is 190cm x 160cm and it is made of corrugated board. The top plate 23 is conical or frustum-shaped and has a 5-degree outward slope to drain rainwater.

[0026] Because debris inevitably travels through the fan 13 during the exhaust of polluted air from the chicken coop, a movable door 25 is installed in the horizontal exhaust duct 21 to facilitate cleaning. The movable door 25 is located on the lowest side of the vertical exhaust vent 24 and is used for periodic cleaning and disinfection. The movable door 25 is 60cm wide and 180cm high, made of corrugated board, and fits well with the side panel of the vertical exhaust duct for a good seal. It has two fixed latches at the top and bottom. The design of the movable door 25 facilitates cleaning and disinfection; chicken feathers, dander, and other contaminants can be periodically removed and disinfected through the movable door 25.

[0027] Because it guides the air in the horizontal exhaust duct 21 to flow smoothly into the vertical exhaust duct 22, a guide plate 26 is installed at the connection between the horizontal exhaust duct 21 and the vertical exhaust duct 22. The guide plate 26 is located at the bottom of the vertical exhaust duct at a 45-degree angle and serves to guide the air upward.

[0028] In addition, a baffle 12 is installed at the air inlet side window 11. This baffle 12 can close the air inlet side window 11 when needed to prevent excessive heat loss outside the chicken house. The baffle 12 can be a sliding plate or a rotating plate.

[0029] The ventilation structure in the above embodiment prevents polluted air from circulating into the chicken house. This design avoids the possibility of polluted air entering through the air inlet window 11 of the other chicken house when two chicken houses are facing each other, thus preventing the farm from becoming self-contaminated. Harmful gases, dust, pathogens, and other particles in the polluted air discharged by the ventilation structure are directly released into the upper atmosphere of the chicken farm and carried away by the high-altitude airflow, greatly reducing odor in the farm area and significantly improving the microenvironment of the chicken farm.

[0030] Because of the use of this ventilation structure, the chicken house can save land area in the chicken farm. Since it solves the problem of cross-contamination between chicken houses, the distance between the houses can be reduced. Each house can reduce the land area by more than 300m2, and 8 houses can save nearly 4 acres of land.

[0031] Example 2

[0032] The optimized ventilation structure for chicken houses proposed in this embodiment is based on the optimized ventilation structure for chicken houses in the above embodiment, with the addition of a return air structure. Its function is to increase the temperature of the air entering the chicken house as much as possible when the ambient temperature is low in winter.

[0033] like Figure 2As shown, the return air structure includes a series of metal pipes. Specifically, the return air structure includes a return air duct 31, a heat exchange pipe 32, and an inner pipe 33. The return air duct 31 penetrates the side wall of the vertical exhaust channel 22. The front end of the heat exchange pipe 32 is connected to the return air duct 31, and the return air duct 31 extends inside the horizontal exhaust channel 21 and the vertical exhaust channel 22. The end of the heat exchange pipe 32 is connected to the inner pipe 33, which is installed inside the chicken house.

[0034] The return air duct 31 is preferably oriented towards the outer wall 10 of the chicken house, with its center 3m-4m above the ground. The return air duct 31, heat exchange pipe 32, and inner pipe 33 are integrated metal pipes, or sealed pipes constructed from corrugated sheets. When using the return air structure, the inlet side window 11 needs to be sealed first by the baffle 12. The high-temperature gas flowing out of the chicken house exchanges heat with the low-temperature gas entering the return air structure in the horizontal exhaust channel 21 and the vertical exhaust channel 22. The heat exchange process mainly takes place at the heat exchange pipe 32. For example, if the outdoor temperature is -20℃, the air temperature entering the inner pipe 33 can be increased by about 15℃ after heat exchange through the return air structure. The return air structure can exchange heat between the air exhausted from the chicken house and the air entering the chicken house, preventing cold air from blowing directly into the chicken house and avoiding chickens getting sick due to cold air blowing directly into them.

[0035] The function of the inner tube 33 is to guide airflow in a specific direction. In this embodiment, the inner tube 33 is installed vertically upward against the inner wall of the chicken house's outer wall 10. Since the external ambient temperature is low, the air entering the chicken house remains cold even after heat exchange. Therefore, the main function of the inner tube 33 is, firstly, to further increase the temperature of the air entering the chicken house by exchanging heat between the air inside the chicken house and the low-temperature gas in the inner tube 33. Simultaneously, because the inner tube 33 guides the air upward, it prevents the air entering the chicken house from blowing directly across the chicken cages.

[0036] like Figure 3 and Figure 4 As shown, due to the large length of the chicken house, multiple exhaust structures 20 and return air structures can be installed. The multiple return air structures are equipped with horizontal pipes 34. The first end of the horizontal pipe 34 connects to the upper end of the aforementioned inner pipe 33, and the second end of the horizontal pipe 34 connects to a horizontally placed heat exchanger pipe 35. In this embodiment, the heat exchanger pipe 35 is densely covered with through holes, allowing the air introduced into the chicken house by the return air structure to be slowed down and its air pressure reduced through the heat exchanger pipe 35, transforming high-speed air into low-speed, low-pressure air. This creates a seamless ventilation experience inside the chicken house, preventing the chickens from getting sick due to sudden cold.

[0037] In actual use, the ventilation structure described in this application significantly reduces the incidence of respiratory diseases in chickens, demonstrating remarkable effectiveness.
