Description

Technical Field

[0001] The utility model relates to the technical field of ventilation of closed poultry breeding sheds, in particular to a closed poultry breeding microcirculation ventilation system. Background Art

[0002] In the large-scale, intensive and efficient meat and poultry production model, the ventilation effect inside the breeding house has a great impact on the growth environment, production performance and economic benefits of the animals in the house. The factors affecting the growth environment of meat and poultry include three main aspects: physical, chemical and biological. Among them, physical factors mainly include temperature, light, ventilation, dust, noise, etc.; chemical factors mainly include oxygen content and harmful gases in the air; biological factors mainly include various viruses, bacteria, molds and other microorganisms. Among the above factors, temperature, humidity, light and harmful gases have a greater impact. The air flow inside the breeding house can effectively improve the temperature, humidity, harmful gases in the house, and reduce the content of microorganisms in the house. It can be seen that ventilation control in the breeding house helps to improve the environmental conditions of the meat and poultry house, which is related to the development and growth of meat and poultry farming, the breeding quality, and the quality of meat products.

[0003] At present, large-scale breeding houses generally use mechanical negative pressure fans to achieve ventilation in the house. A certain number of negative pressure fans are installed at one end of the house, and an adjustable damper is installed on the wall at the other end, and an adjustable air inlet window is installed on the side walls. When the negative pressure fan is running, the turbid gas in the house is continuously discharged to the outside of the house, forming a certain negative pressure in the house, forcing the fresh air outside the house to enter the house through the damper at the open end and the air inlet window on the side wall. The environmental controller determines the number of negative pressure fan units to be opened according to the breathing volume of the animals in the house and the current actual temperature. Different numbers of fans opened represent different ventilation levels. When the temperature in the house is low, the number of fan units opened is small. When the temperature rises, the environmental controller automatically realizes ventilation upgrade, and the number of fans opened and the ventilation time gradually increase, that is, the ventilation volume is increased. To ensure the physiological needs of normal growth and development of meat poultry.

[0004] However, this traditional poultry house ventilation mode has several disadvantages. For example, longitudinal ventilation may cause uneven ventilation from front to back, breeding equipment may form wind resistance and cause ventilation dead corners, and there is insufficient ventilation in places where poultry are concentrated. Utility Model Content

[0005] In order to overcome the above problems existing in the prior art, the utility model proposes a closed poultry breeding microcirculation ventilation system.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a closed poultry farming microcirculation ventilation system, including an electrical control module, a refrigeration module, a sterilization and drug administration module, an air flow control box, and a dehumidification module. The air flow control box is provided with an air inlet on one side and an air outlet on the other side. The sterilization and drug administration module and the refrigeration module are provided below the air flow control box. A ventilation duct is provided above the air flow control box. A main power fan and a duct-dispersed wind-type two-way fan are installed in the ventilation duct. The other end of the ventilation duct is connected to the poultry house. The ventilation duct is provided on both sides of the poultry activity area. There are multiple dehumidification modules, and the multiple dehumidification modules are arranged at intervals in the ventilation duct. The electrical control module realizes the opening and closing of the entire ventilation system.

[0007] The above-mentioned closed poultry farming microcirculation ventilation system also includes an intake air sterilization module, which is arranged at the air inlet. The outside air first passes through the intake air sterilization module and then enters the airflow control box.

[0008] The above-mentioned closed poultry farming microcirculation ventilation system also includes an emergency oxygen supply module, which is located below the airflow control box. An electric control valve is provided at the communication position between the emergency oxygen supply module and the airflow control box.

[0010] In the above-mentioned closed poultry farming microcirculation ventilation system, a power fan is arranged in the dehumidification module, and a membrane dehumidification is arranged in the dehumidification module, and the humid air is separated from the water by the dehumidification membrane.

[0011] The beneficial effects of the utility model are that the ventilation ducts are arranged on both sides of the poultry activity area and adopt a dispersed wind design, which has good comfort and does not affect the physiological condition of meat poultry; by arranging an emergency oxygen supply module, it is effectively avoided that when the poultry is sick, lacks oxygen or there is a problem with ventilation in the house, the death of poultry due to lack of oxygen is avoided, and the life of the poultry is effectively protected or maintained; by arranging a refrigeration module, the occurrence of summer smoldering accidents is reduced; by arranging an air intake sterilization module, the air entering the poultry house is preliminarily sterilized, avoiding the situation of collective infection of poultry in the poultry house due to viruses in the air.

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] like Figure 1 As shown, the present embodiment discloses a closed poultry farming microcirculation ventilation system, including an electrical control module 2, a refrigeration module 1, a sterilization and medication module 3, an air flow control box 12, and a dehumidification module 9. An air inlet 10 is provided on one side of the air flow control box 12, and an air outlet 5 is provided on the other side. The sterilization and medication module 3 and the refrigeration module 1 are provided below the air flow control box 12. A ventilation duct 7 is provided above the air flow control box. The ventilation duct is provided on both sides of the poultry activity area. A main power fan 6 and a pipeline wind-dispersing bidirectional fan 8 are installed in the ventilation duct 7. The other end of the ventilation duct is connected to the poultry house. A plurality of dehumidification modules 9 can be provided according to the size of the poultry house. The plurality of dehumidification modules are arranged at intervals in the ventilation duct. A power fan is provided on the dehumidification module. When working, the fan generates power to send the humid air in the house into the dehumidification module 9. The humid air passes through the dehumidification membrane to achieve steam / water separation. The dry air passes through the dehumidification device and remains in the house. The water vapor is discharged to the outside of the poultry house through the water guide pipe to achieve a dehumidification effect.

[0017] In this embodiment, the ventilation system also includes an air inlet sterilization module 11, which is arranged at the air inlet 10. The outside air first passes through the air inlet sterilization module and then enters the air flow control box. An emergency oxygen supply module 4 is also provided, which is located below the air flow control box 12. The position where the emergency oxygen supply module 4 is connected to the air flow control box 12, the air inlet, the air outlet, the position where the refrigeration module is connected to the air flow control box 12, the position where the sterilization and drug delivery module is connected to the air flow control box 12, and the position where the dehumidification module is connected to the ventilation pipeline are all provided with electric control valves. The electrical control module 2 is intelligently controlled to realize the opening and closing of the entire ventilation system, effectively control the intelligent conversion of each module, and enable the free conversion of ventilation, sterilization, cold air, dehumidification and supply.

[0018] In this embodiment, the emergency oxygen supply module is an emergency means designed in the poultry house. When the poultry is sick, hypoxic or has ventilation problems in the house, emergency oxygen supply measures can be taken to ensure that the life of the poultry is protected or maintained. Solid oxygen or compressed oxygen is set in the emergency oxygen supply module. The electric control valve at the position where the emergency oxygen supply module 4 is connected to the air flow control box 12 is opened, and other electric control valves are closed to send oxygen into the air flow control box 12. The main power fan sends the oxygen into the ventilation pipeline, and then the pipeline dispersed wind bidirectional fan sends it into the poultry house, so as to alleviate the emergency hypoxia caused by various reasons during the breeding process.

[0019] When this embodiment is used, the electric control valve at the air inlet is opened, and other electric control valves are closed. The air sterilized by the air inlet sterilization module 11 is sent into the ventilation pipeline through the main power fan 6, and then the pipeline wind-dispersing two-way fan 8 on the ventilation pipeline evenly sends the air into the poultry house to achieve ventilation of the poultry house. When exhausting, the electric control valve at the air outlet is opened, and other electric control valves are closed. The high-humidity, dirty, and harmful gases in the poultry house are discharged from the poultry house through the air flow control box 12 through the pipeline wind-dispersing two-way fan 8 and the main power fan 6 on the ventilation pipeline, thereby completing the goal of supplying air and exhausting high-humidity and harmful gases.

[0020] When the poultry house needs to be sterilized, the slow-release sterilizer or disease prevention and treatment agent is placed in the sterilization and dosing module 3, the electric control valve connecting the sterilization and dosing module with the airflow control box 12 is opened, and other electric control valves are closed. Through the slow release of the drug, the main power fan sends the agent into the ventilation pipeline, and the pipeline dispersed air bidirectional fan 8 sends the agent into the poultry house, so as to achieve the purpose of removing harmful gases, disinfecting and sterilizing, and preventing and treating related poultry diseases.

[0021] When the temperature is high in summer, the poultry house needs to be cooled. Open the electric control valve connecting the refrigeration module and the airflow control box 12, close other electric control valves, start the main power fan, and send the cold air into the ventilation duct. The pipeline dispersed air two-way fan 8 sends the cold air into the poultry house. The cold air is mild and is directly sent to the poultry gathering area. It can effectively supplement the cooling of the wet curtain and reduce the occurrence of smoldering accidents in emergency situations.

[0022] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
