Description

Technical Field

[0001] The utility model relates to the technical field of meat and poultry breeding, and provides a pipe-guided ventilation device for a closed meat and poultry breeding shed. Background Art

[0002] In the large-scale closed meat and poultry breeding mode, the ventilation and air change of the breeding shed are the most crucial links in breeding, which are related to the growth environment, production performance and economic benefits of meat and poultry. Generally, in large-scale closed meat and poultry breeding, 16,000 - 22,000 can be bred in a breeding cycle in a standard shed, with a density of 12 - 20 per square meter, and 100 cubic meters of feces can be produced in one breeding cycle. Such a high breeding density and excreted feces can cause the air in the shed to be turbid and lack oxygen, with a large amount of harmful gases such as ammonia, hydrogen sulfide, carbon dioxide, carbon monoxide and methane, and cause meat and poultry to lack oxygen and suffer from chronic poisoning. When the ammonia concentration reaches 20 ppm and lasts for more than 6 weeks, obvious lesions occur in the lungs of meat and poultry; when it reaches 50 ppm, it can cause tearing and runny nose; when it is 60 - 80 ppm, it can cause mucosal congestion, edema, conjunctivitis, keratitis and tracheitis, and the egg production significantly decreases; when meat and poultry are in an environment of 25 ppm, the weight gain and feed utilization rate are significantly reduced. Ammonia is also easy to cause meat and poultry poisoning, making their appetite decrease or disappear completely, and even causing death in severe cases. When the hydrogen sulfide content in the air in the shed is higher than 6.6 ppm, meat and poultry are prone to photophobia and tearing, pharyngeal burns, and are prone to rhinitis, tracheitis, and even cause pulmonary edema. In addition, hydrogen sulfide is easily soluble in water. After contacting the respiratory mucosa of poultry, it combines with sodium ions therein to form sodium sulfide. Its strong stimulating effect can cause ophthalmia and respiratory tract inflammation. After sodium sulfide enters the blood, it is hydrolyzed to release hydrogen sulfide again, which has an asphyxiating effect on cell respiration, thus causing tissue hypoxia in the body, leading to respiratory paralysis and asphyxiation death. In such an environment, viruses, bacteria and molds are extremely easy to breed in the shed, threatening the life safety of meat and poultry. Most of the designs of the traditional closed meat and poultry breeding shed ventilation systems in our country adopt the negative pressure longitudinal ventilation method. Thus, it can be seen that the ventilation and air change of the breeding shed are crucial for breeding. It discharges harmful gases, supplies sufficient oxygen for the growth of meat and poultry, keeps the relative temperature and humidity in the shed appropriate, and reduces the retention of pathogenic microorganisms such as bacteria and viruses in the shed.

An air outlet end is arranged at the bottom of the light energy ion sterilizer 3, and the air outlet end is connected to the active power fan 5 through the air supply duct 4. The active power fan 5 can suck the fresh air outside the shed into the shed through the light energy ion sterilizer 3. The light energy ion sterilizer 3 adopts light energy ion technology to disinfect and sterilize the fresh air, so as to ensure that the fresh air entering the shed is clean fresh air without pathogenic microorganisms.

[0020] A plurality of layers of ultraviolet lamps 11 and a plurality of layers of titanium dioxide nanomesh 10 are arranged in the light energy ion sterilizer 3, and the ultraviolet lamps 11 and the titanium dioxide nanomesh 10 are arranged at intervals. An air flow diffuser 9 is arranged inside the air inlet end of the light energy ion sterilizer 3, and the air is evenly distributed in the light energy ion sterilizer 3 through the air flow diffuser 9.
