An Air Circulation System for Dairy Farms with Sterilization and Filtration Function

Abstract

The invention discloses a cow breeding shed air circulation system with disinfecting and filtering functions and belongs to the technical field of cow breeding. The cow breeding shed air circulation system comprises two circulation pipelines and multiple air pumps arranged on the circulation pipelines. The two circulation pipelines are connected through a circulation air supply device. An efficient disinfecting and filtering device is arranged between each circulation pipeline and the circulation air supply device. Each circulation pipeline is provided with an exhaust pump, a temperature adjusting device and an air inlet pump. A backflow preventing bend is arranged at the end of each circulation pipeline. A residue filtering net, a first layer of ammonia gas filtering net and a second layer of ammonia gas filtering net are arranged in each backflow preventing bend. Each air inlet pipe is provided with a disinfecting device and an inlet air flow adjusting valve. Heat preservation layers are arranged in the circulation pipelines and the backflow preventing bends. The cow breeding shed air circulation system is reasonable in design, simple, convenient to use and capable of conducting circulation filtering and purifying on air of a cow shed, cleanliness of the air in the cow shed is ensured, air is extracted from the outside and disinfected and filtered, the air in the shed is supplemented, ammonia gas is removed through the ammonia gas filtering nets, and the air in the cow shed is ensured.

Description

technical field [0001] The invention relates to an air circulation system for a dairy cow breeding house, in particular to an air circulation system for a dairy cow breeding house with a disinfection and filtering function, and belongs to the technical field of dairy cow breeding. Background technique [0002] Dairy cows are yellow cattle of dairy breeds. They are excellent breeds that have been highly selected and bred. The dairy cows in China are mainly black and white cows. This breed has been introduced from the cattle and sheep breeding base of Shandong Provincial Animal Husbandry Bureau in 1980. This breed has strong adaptability, Wide distribution, high milk yield, and resistance to rough feeding. Black-and-white cows are also called Chinese Holstein cows. Chinese Holstein cows have a history of more than 100 years. The breeding process is very complicated. Because cows can produce milk, many Dairy cows are raised in all regions, and when raising dairy cows, cold prot...

[0002] Dairy cows are yellow cattle of dairy breeds, which have been highly selected and bred. The dairy cows in China are mainly black-and-white cows. This breed has been introduced from the cattle and sheep breeding base of Shandong Provincial Animal Husbandry Bureau in 1980. This breed has strong adaptability, Wide distribution, high milk yield, and resistance to rough feeding. Black-and-white cows are also called Chinese Holstein cows. Chinese Holstein cows have a history of more than 100 years. The breeding process is very complicated. Because cows can carry out milk production, many Dairy cows are raised in all regions, and cold protection and warmth are important measures when raising dairy cows. However, different feeding and management links require different temperatures. In practice, giving appropriate temperatures to each link according to the physiological needs of dairy cows can better improve the temperature. The economic benefits of raising dairy cows are cold-resistant and not heat-resistant, but there must be a certain limit to the cold. Generally, the most suitable temperature for dairy cows is 12°C to 14°C, and the most suitable temperature for pregnant and lactating cows is 16°C. Currently, the most suitable temperature for dairy cows on the market is The greenhouses in the greenhouses are all ordinary greenhouses. In terms of temperature control, the traditional method of setting a stove in winter and blowing fans in summer is adopted. However, the method of blowing fans cannot substantially reduce the temperature in the greenhouses. The traditional method cannot control the temperature and increases manual labor. Moreover, the existing cooling system in the cowshed does not have the function of air circulation, let alone the function of sterilizing and filtering the air, and cannot reduce the content of amines in the cowshed, which is not conducive to the breeding of dairy cows, and cannot effectively serve modern Development of aquaculture
