Description

A ventilative system of a pig farm

The present invention relates to a ventilation system of a pig house, in particular, to make the distribution of the air in pigs evenly distributed, and to reduce the temperature difference in the breeder by preheating and cooling according to the temperature difference of the air in the breeder, and to adjust the amount of ventilation to adjust the optimal growth environment It is related to the ventilation system of pig breeders to be able to provide.

As is well known, the improvement of living standard according to economic development, the continuous increase in meat consumption, the mass production of livestock development, the mass supply of livestock products, and the import and export of low-priced meat by trade, the price and Quality competition is taking place.

This competition gives consumers the freedom to choose and economic gains by choosing cheap livestock, while producers will not seek to reap the benefits of investment by increasing purchasing power and minimizing the cost of production through advanced product discrimination. It is impossible.

As a result, producers have to diversify their production facilities to improve quality while at the same time focusing on cheaper producers.

Therefore, the livestock farmers raise a large number of pigs for the improvement of productivity and quality, and achieve an automated facility by large breeders for breeding.

These automated houses are managed by cooling, heating, ventilation, and feeding based on more systematically researched data on swine water, temperature, ventilation, and heat loss.

In the automatic barn as described above, the cooling, heating, and ventilation system has a problem that it is very difficult to apply to each barn as uniform data according to the conditions of the barn and the tonnage and season.

Therefore, there was a hassle that managers had to manually manage the barn system, and especially in the ventilation system, the temperature difference between day and day is severe and it is very difficult to manage.

For example, in the summer, the zookeepers can be opened as much as possible to obtain the cooling effect through natural ventilation, and in winter season, the airtightness can be sealed to obtain the heating effect due to the thermal barrier. The problem of severely inhibiting the growth environment is generated. As such, the increase in carbon dioxide and odors and toxic gases generated from the excrement make the management of the barn difficult and lead to the development of infectious diseases.

In addition to the seasons, the temperature difference between day and night and the wind strength in each season is remarkably different, which makes it necessary to apply a system suitable for the season, day and night.

In Korean Patent No. 1561,3 for improving the above problems, the ventilation device of the pen is composed of a waiting room where external air flows into one side of the pig house so that the air passes through the tube passing through the pen inside with the preheating of the introduced air. Ventilation system for supplying preheated air through penetrate into the pen and ventilating fan for sucking and discharging air through the bottom of pig house.

The bottom surface has provided a manure processing device for pumping the manure to the pipe formed with a mesh to pass only the excrement.

Ventilation system in this selection has a disadvantage that the preheating chamber of the incoming air is composed of one on the ground side wall of the barn, so that the temperature difference due to the outside temperature of the barn cannot be achieved, and the preheating effect is extremely low. In addition, there are a large amount of discharge holes in all directions, and when a small amount of air is supplied in the winter season, a large amount of air is discharged from the inlet side, so that the amount of exhaust air is very small at the end of the plastic pipe, that is, the other side of the house, so the air is balanced in the house. Not only can not supply the air directly sprayed in the spring and autumn when the direct supply of strong air to the pigs when the temperature difference on the skin of the pig sharply causes the problem of causing harm, the tube is reduced by the air pressure decrease in the tube There is a risk of the pigs tearing down to the bottom.

In addition, in another embodiment, while supplying the inlet air between the ceiling and the roof, the preheated air is supplied to the air discharge holes drilled in the ceiling. However, this embodiment has a difficult configuration and the air circulation is not active. The circulation flow of the air is not good in the inside, and another embodiment of the present invention allows the air introduced from the outside of the house to be supplied after being introduced into the preheating chamber through the pipeline through the basement, but this configuration is difficult to supply sufficient air and also the installation cost. There is a problem that is much use.

Accordingly, in order to improve the above disadvantages of the vinyl tube, the Korean Utility Model Registration Nos. 173829 and 173830 introduce external air into the pig house, but the ground water is injected into the air passage outside the livestock house to achieve heat exchange, and then the top of the pig house. In addition to supplying the vinyl duct horizontally installed on the ground and the discharge hole is divided into the upper or lower portion of the vinyl duct so as to supply and circulate the desired air by drilling.

This configuration also does not solve the disadvantages of vinyl tubes, and in some cases a large amount of exhaust does not achieve a balanced distribution, and the air flow, circulation and ventilation in the barn can not be effectively exerted, as well as directly in the air flow pipe Due to the injection, the heat exchange effect is low, or the temperature is severely generated and the temperature difference is a problem that the pig suffers cold.

In view of the problems with the ventilation system in the conventional barn as described above (hereinafter referred to as "donsa"), the present invention has been devised to improve this. In particular, the present invention has a dual configuration of the preheating chamber to minimize the temperature difference in the barn by increasing the preheating effect. The structure of the inlet air discharge pipe in the house can be adjusted according to the season with the low installation cost, and the structure is simple with the effect of reducing the cold and fuel consumption while reducing the damage caused by the temperature difference. It is an invention for the purpose of preventing the conventional closed end by adjusting the air discharge amount and speed according to the.
