Description

A ventilative system of a pigpen

The present invention equally and stably supply external fresh air to pig breeders, mudang pigs (wineless pigs) and piglets (hereinafter referred to as pigs) to prevent breeding pigs from damage caused by temperature differences and occur in pigs. The present invention relates to a ventilation system for pigs that can provide an optimal growth environment by quickly discharging harmful gases and dust.

As is well known, the improvement of living standards due to economic development, the continuous increase in meat consumption, the mass supply through mass production following livestock development, and the import and export of low-priced meat through trade, the competition in price and quality in the livestock sector This is being done.

In livestock farming, the mass farming and breeder's automation facility will be established to improve productivity and quality. However, the automated farming house will be equipped with cooling, heating and heating based on more systematic studies on money, temperature, ventilation and heat loss. It is managed by ventilation and feed.

However, the data of cooling, heating, and ventilation system in the automatic pig house is designed based on the approximate data without satisfying the conditions of each livestock farm, the temperature change according to the pig's conditions, the size of the pig house, the number and season of the pigs, and the region. This is a problem that is difficult to apply to livestock farmers.

Therefore, each livestock farmer has to manage the pig company's system manually. Especially in the ventilation system, if the temperature difference between the four seasons and the day and night temperature are big like Korea, the problem is more difficult to manage.

For example, heating and ventilation are achieved at the minimum cost with minimal wear and exhaust during winter in winter, and cooling and ventilation is required with maximum wear and exhaust during the hot summer during summer.

However, ventilation can not be achieved by simply opening and closing the open door of the pig company. In a closed pig house, turbidity is severe due to the increase of carbon dioxide and odor caused by the breathing of pigs and pig meal. Carbon dioxide, odors and dusts such as these will make pig management difficult and cause infectious diseases, and will cause very fatal damage to piglets.

In order to improve the above problems, the applicant's prior registration No. 20-0352121 of "Applicant's ventilation window automatic opening and closing device of Muchang pigs", No. 20-0333829 "Don's ventilation system", No. 10- No. 0388265, "Pig ventilation system", 20-0351889 "Pig ventilation system", 10-0790345 "Muchang pig ventilation system, No. 10-0693071" Ventilation system of laborers "and a number of patented inventions can see.

In the preceding invention, a preheating chamber in which air from the outside is temporarily formed is formed on one side of the pig house, which is composed of a pig room, a pig flour collecting chamber, and a flooring material, and a vent is provided for discharging the indoor air to the outside. The flap keeps the temperature difference within the pig house to a minimum, thereby reducing the damage caused by the temperature difference, while reducing the cooling and heating costs, and controlling the air discharge amount and speed according to the pig's conditions, seasons, and temperatures to prevent conventional closure. I have.

However, there are many differences in temperature, wind speed, and season depending on the structure of the pigs, the mountains, fields, etc., which makes it impossible to achieve optimal temperature and oxygen supply, and when heat waves and tropical nights occur due to abnormal temperature in summer. Because they do not achieve a large number of breeders, the growing pigs heat up and the stress increases, which slows down the growth. In addition, the cold air directly hits the respiratory disease occurs, the skin is rough and there is a lack of gloss has a disadvantage of poor marketability.

In winter, the pigs keep the internal temperature at 18 ~ 20 ℃ to fit the minimum oxygen demand for pigs and exhaust the minimum gas so that the pig can grow to the right temperature without heating. As it is the most suitable cold and not hot season, it controls excessive amount of inflow and outflow. In the hot summer, the inside of the room is heated with maximum ventilation, so make a lot of air and make the wind speed 0.5 ~ 1m / sec. The situation is required to achieve the flow of air to lower the body heat by passing by.

In order to satisfy the above conditions, the applicant is developing a technology previously filed with the pre-registered invention as described above. However, such prior art cannot satisfy the optimal condition because it cannot be determined as the best configuration. have.

In particular, the conventional dressing system has a low flow rate as the cold air is rapidly descending as the blowing air is injected from the air, and the sensation temperature is low as it rubs with the pig. It adversely affects the development and causes respiratory diseases such as pleurisy, bronchial disease and rhinitis, causing the risk of death.

The present invention has been made in order to improve the problems as described above, but in particular to achieve the inlet according to the plurality of inlet stages and the step-by-step exhaust in Muchangdonsa, providing the optimum environment in the inlet and simple to manufacture It is an object of the present invention to further improve the growth conditions by making the supplying and exhausting of the air easy and uniform in the pig house.

In order to achieve the above object of the present invention, a distribution duct for injecting and supplying external fresh air into a pig house, and a distribution pipe for uniformly injecting the air supplied from the pig duct into the pig house, and odors and gases generated in the pig house. It consists of a step-by-step exhaust duct and an exhaust fan to effectively exhaust dust.
