Description

The ventilation system for windowless swine housing

The present invention relates to a ventilation system for use without pigs, and more specifically, to supply air outside the pig house to the inside of the pig house and to discharge the polluted air inside the pig house to the outside, the pig breeding space and pigs are not buffered inside the pig house After separating into a space, the outdoor air is not supplied directly to the breeding space, but is indirectly supplied to the breeding space through the buffer space to prevent direct contact between the pig and the outdoor air, and the ventilation duct and pig yarn for supplying the outdoor air into the pig house. The present invention relates to a ventilation system for useless pigs, in which an interval and a height of an exhaust fan for discharging internal air are appropriately set so that an optimal air flow and smooth ventilation are achieved.

Most domestic pigs that raise pigs among livestock raising houses are open type pigs that allow natural ventilation using open walls without proper ventilation system.In summer, natural ventilation alone is not enough. In winter, in order to prevent the cold to block the walls of the pigs with a heat cover, the ventilation of the pigs is extremely poor, which has a structural defect that has a very bad effect on the breeding of pigs.

In Korea, the four seasons are clearly distinguished and there are significant differences in the seasonal climate characteristics.The annual difference in temperature is very large, reaching 60 ℃ in the central region, and the daily difference is more frequent than 10 ℃. Despite the difference in climate, most livestock farms prefer winch type pigs, or open type pigs, that open and close both open walls with vinyl or non-woven thermal insulation covers.

As mentioned above, domestic livestock farmers prefer open pigs because the construction cost is relatively low, which is inevitable in the case of pig farmers whose income level is not high. In spite of the blocking, the warming effect is very low and the ventilation function is sharply dropped, thereby raising the mortality rate of the pigs raised by the respiratory disease.

Moreover, in winter and other non-season seasons, at night, the thermal insulation cover blocks the open walls of the pig house. In this case, the pig's internal air, which is not well ventilated, contains excessive heat and moisture, suspended dust, odors, gases and bacteria. The back contains a large amount of respiratory diseases can not easily occur.

That is, the conventional open type piglet has a problem that the respiratory disease which accounts for most of the pig mortality can hardly be prevented because the ventilation function of supplying fresh air and exhausting the air in the fresh piglet is very insufficient.

In order to solve the above problems of open pigs, remodeling to remove open walls is made, or construction is made so that there is no open wall from the beginning. By making it happen, a method of increasing pig productivity while reducing mortality of pigs is being attempted.

The changchangdonsa, a retaining wall of a suitable height is made on the concrete floor, the insulation panel wall is erected on the retaining wall, the roof is mounted on the top of the wall, the changchangdonsa can not be natural ventilation is provided with a ventilation device Therefore, compared with the open pig house has the advantage that can significantly reduce the frequency of occurrence or prevention of respiratory diseases in pigs.

As the ventilation device of the changchang pig company as described above, "ventilation system of pig farming company" published in Korean Patent Publication No. 388265, "exhaust system of changchang pig company" published in Patent Publication No. 291853, Patent Publication No. 790345 There are many such as the "ventilator of Muchang pigs" published in Japanese Patent Application No. 2008 and the "angular pig ventilator of Muchang pigs" published in Japanese Patent Application Publication No. 2008-90774.

However, the above invention, the air supply duct outside directly to the pig house, or the air supply duct is biased to one side inside the pig house, or the location of the air outlet or the exhaust port discharged air inside the pig house There are disadvantages in the function and structure for ventilation, such as improper. When applied on site, it may be difficult to obtain adequate ventilation and adequate airflow.

An object of the present invention is to provide a comfortable environment inside the pig house through the uniform air flow and smooth ventilation.

In addition, there is another object of the present invention to improve pig productivity by preventing or minimizing respiratory diseases in pigs through seasonally appropriate ventilation.

The above object of the present invention is achieved by a buffer space which is an empty space partitioned in the pig house so that the outdoor air introduced from the pig house can stay temporarily before being fed to the pig.

In addition, it is achieved by a blower duct, an exhaust fan, an auxiliary air intake provided on the wall, and a variable air flow rate blower installed according to standardized standards such as a constant height, size, and spacing.

Ventilation system using no pigs of the present invention, because the outside air is indirectly supplied to the breeding space through the buffer space in the pig house, especially in the winter when there is a significant difference from the general conditions such as temperature and humidity compared to the air in the breeding space The cold and dry outdoor air does not come into direct contact with the pig, and the ventilation ducts and exhaust fans are arranged at the proper height and spacing, so that the air flow is minimized, the ventilation is uniform, and the comfortable environment is created. Improved, there is an advantage that the mortality rate due to respiratory disease is significantly reduced by efficient ventilation.

In addition, there is an advantage that a uniform ventilation can be always performed regardless of the season by the auxiliary air intake of the wall and the air flow variable blower fan.

The present invention relates to a ventilation system installed in the pig house.

The ventilation system of the present invention has a technical feature of supplying outdoor air to a pig house and allowing the indoor air inside the pig house to be discharged to the outside of the pig house, so that the outdoor air supplied to the pig house does not come into direct contact with a pig being raised. .

That is, the waste disposal system of the present invention divides the inside of the pig house into a buffer space as a breeding space where the pigs are raised and an empty space where the pigs are not raised so that the pigs being raised are not immediately exposed to the outdoor air supplied to the pigs. In addition, the outdoor air is introduced into the buffer space once, and the introduced outdoor air is stabilized in the buffer space, and then is indirectly supplied to the breeding space.

In addition, in the ventilation system of the present invention, a plurality of blowing ducts and exhaust fans, etc. installed in the pig house are installed at a constant height and interval range so that the air flow is uniform and smooth ventilation is achieved.

In the ventilation system of the present invention as described above, the outdoor air is introduced into the buffer space in the pig house, the outdoor air introduced into the buffer space is supplied downward from the top of the breeding space through the ventilation duct, corresponding to the supply amount of the outdoor air The indoor air in the breeding space is discharged to the outside through the exhaust fan of the exhaust port installed on the side wall of the wall.

At this time, a driving force for allowing outdoor air to flow into the breeding space from the outside of the pig house and then to the breeding space through the ventilation duct is provided in the breeding space as the exhaust fan discharges the indoor air of the breeding space to the outdoors. It is generated by the negative pressure formed, that is, the suction force of the exhaust fan.

As used herein, the term "side wall" refers to "two walls having a relatively long length while facing in the width direction" on the wall of a pig that forms a planar visual shape, and the "front wall" refers to the side wall while facing in the length direction. Compared with two shorter walls compared to the wall with the entrance (main door) means.

In Korea, there is a large climate deviation according to the season. In order to prevent the air flow from flowing faster than necessary while excessive negative pressure is formed inside the breeding space by the fan, the auxiliary inlet provided with an opening and closing means is closer to the exhaust fan. It may be provided at the upper end of the side wall in the position, and a blowing fan may be provided between the main air intake of the buffer wall and the ventilation duct which are erected between the front and rear walls so as to partition the breeding space and the buffer space.

In other words, if there is a large difference between indoor and outdoor climates of the pigs, or if it is necessary to temporarily increase the air flow rate or air flow rate, it is possible to cope with the method of appropriately using the opening and closing means of the auxiliary suction port or a blowing fan.

Ventilation system of the present invention is optimized for pigs of a certain size in a rectangular shape in plan view, especially pigs having a length of 25 to 40 m, a width of 8 to 15 m, a side wall height of 2.5 to 3.5 m and a ridge height of 4 to 5 m. to be.

When the ventilation system of the present invention is installed in the same size as above, the ventilation duct has a height of 2 to 2.5 m, the distance between the blowing ducts is 2 to 2.5 m, the height of the exhaust fan is 1 to 1.5 m, and the interval between the exhaust fans is It is preferably set to 4.5 to 6.5 m, and the distance between the wall and the duct and the wall and the exhaust fan is preferably in the range of 30 to 60% of the space between the duct and the space between the exhaust fans, respectively.

However, as described above, the installation conditions of the blower duct, the exhaust fan, and the auxiliary suction port are limited. If the blower duct height does not reach 2 m, the air flow may be increased more than necessary. If the height of the exhaust fan is less than 1 m, the air flow can be increased faster than necessary as the discharge of relatively cold air increases, and if it exceeds 1.5 m, the air flow becomes too slow to discharge pollutants such as dust. This is because smooth air flow and ventilation cannot be achieved.

Details of the effects and the resulting effects, including the object and technical configuration of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.
