Description

[0001] VENTILATING SYSTEM FOR LIVESTOCK HOUSE [0002]

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a ventilating apparatus, and more particularly, to a ventilating apparatus using a shaft for ventilating air inside a barn, such as a cattle or pig.

The barn is a structure for efficiently managing livestock such as cattle and pigs and for protecting livestock from natural weather such as snow and rain. Because these animals hold large numbers of livestock at the same time, harmful gases and odors are generated from the excrements of the animals in the animals. Therefore, a ventilator should be installed in the house to discharge these harmful gases and odors to the outside to keep fresh air inside the house.

FIG. 1 is a cross-sectional view showing a conventional ventilating apparatus using a spring.

Referring to FIG. 1, a spring type ventilating apparatus 20 includes a duct 21 installed on a sidewall of a housing 10, a damper 22 for regulating the amount of air flowing into the housing 10 from the duct 21, And a spring 23 for regulating the opening and closing of the damper 22.

The duct 21 has an inlet 21a through which air is introduced from the outside and an outlet 21b through which the air introduced into the duct 21 is discharged into the housing 10. The damper 22 is installed on the side of the discharge port 21b and automatically opens according to the ventilation amount of the air inside the housing to introduce outside air into the housing 10. Particularly, the damper 22 is automatically opened and closed by the spring 23. This spring-type ventilating apparatus 20 is disadvantageous in that the opening / closing of the damper 22 is affected by a change in elastic force of the spring 23 have.

That is, when the damper 22 is opened, the spring 23 is pulled. As the extension length of the spring 23 becomes longer, the elasticity index of the spring 23 becomes higher and the damper 22 can not be fully opened. Also, the elastic coefficient of the spring 23 is reduced due to the use for a long period of time or adhesion or corrosion of foreign matter, and the sealing force by the damper 22 is lowered. Therefore, the outside air can not flow into the central portion of the housing, but is spread widely only in the region adjacent to the outlet 21b, so that ventilation of the inside of the housing 10 by the ventilator 20 can not be achieved.

2 is a view showing a conventional ventilating apparatus using a shaft using the weight of a damper.

Referring to FIG. 2, the ventilating apparatus 30 includes a duct 31 installed on the side wall of the housing 10 and a damper 32 for controlling the amount of air flowing into the housing 10 from the duct 31 .

The duct 31 has an inlet 31a through which air is introduced from the outside and an outlet 31b through which the air introduced into the duct 31 is discharged into the housing 10.

The damper 32 is installed inside the duct 31 and automatically opens according to the ventilation amount of the air inside the housing to introduce outside air into the housing 10. The ventilation device 30 shown in Fig. 2 has a structure in which the damper 32 is opened and closed by the weight of the damper 32. The structure of the ventilation device 30 is relatively simple, Long-term use is possible. However, since the amount of the inflow of the outside air increases with the increase of the ventilation amount in the housing 10, the area of the damper 32 that resists perpendicularly to the inflow air increases as the inflow amount of the outside air increases It is different. Therefore, the shaft-use ventilator 30 can not keep the flow rate of the dressing constant according to the change in the ventilation amount in the housing 10.

Especially, it is very important to control the air velocity of the outside air flowing horizontally from the ventilator to the ground depending on the size and structure of the housing.

That is, when the housing width is narrow, if the wind speed of the outside air flowing into the housing is too high, the introduced outside air is immediately given to the domestic house animal after it hits the opposite wall. In the case of pigs, the cold stress caused by this external air may cause the immune system to become weakened, leading to disease or death. On the other hand, if the wind speed of the outside air flowing into the housing is too low, the outside air is provided only in the area immediately below the ventilation device, so that the air inside the house and the inside air can not be mixed properly.

When the wind speed of the outside air flowing into the housing is too high when the housing width is wide, it is impossible to make an ideal air mixing inside the housing by colliding with the outside air flowing from the ventilation device on the opposite side. On the contrary, if the wind speed of the outside air is too low, the outside air is provided only in the area immediately below the ventilation device, and the ventilation is not properly performed, and the outside air is directly supplied to the livestock located in the area adjacent to the ventilation device.

Korean Registered Utility Model No. 20-0443163 (2009.01.08) "Exhaust and ventilation of container type housing" Korean Registered Patent No. 10-1137965 (Apr. 12, 2012) "Ventilation System of Pigs"

3 to 6, a plurality of axial ventilating apparatuses 100 according to the present invention are installed on the side wall 11 of the barn 10 to ventilate the inside of the barn 10, as shown in FIG.

Specifically, the axial ventilator 100 includes a duct 110, a vertical member 120, and a flow control panel 130.

The duct 110 is coupled to the side wall 11 of the housing 10 and guides the outside air to the inside of the housing 10 (PI). In this embodiment, the duct 110 has a generally box shape as shown in Fig.

The duct 110 includes a side plate 111, an upper plate 112, an outer lower plate 113, and an inner lower plate 114.

The side plate 111 is vertically disposed with respect to the ground to form an inner space into which the outside air flows and a portion corresponding to the ventilation hole 11a formed in the side wall 11 is opened to connect the inside space of the duct 110 and the housing 10, The inner space PI is communicated.

The upper plate 112 extends vertically from the side plate 111 and is inserted into the ventilation hole 11a at one end for coupling the duct 110 to the housing side wall 11.

The outer bottom plate 113 is vertically extended from the side plate 111 to face the top plate 112 and a first inlet 113a for introducing the outside air into the duct 110 is formed.

The inner lower plate 114 is provided between the upper plate 112 and the lower outer plate 113 and extends vertically from the side plate 111 to face the upper plate 112. The inner bottom plate 114 is formed with a second inlet 114a through which the outside air flows and one end is fitted into the ventilation hole 11a in order to connect the duct 110 to the housing side wall 11.

In particular, the inner bottom plate 114 separates the inner space of the duct 110 into a primary receiving space IS1 and a secondary receiving space IS2. Here, the primary receiving space IS1 is defined by the side plate 111, the outer bottom plate 113 and the inner bottom plate 114, and the outside air is introduced through the first inlet 113a. The secondary wearing space IS2 is defined by the side plate 111, the upper plate 112 and the lower inner plate 114 and the outside air flows from the primary receiving space IS1 through the second inlet 114a. Here, the secondary receiving space IS2 communicates with the internal space PI of the housing 10 through the vent 11a.

In this embodiment, the outer bottom plate 113 is folded upward at one end adjacent to the housing side wall 11 and is coupled to the lower face of the inner bottom plate 114.

Meanwhile, a vertical member 120 and a flow control panel 130 are provided in the duct 110.

The vertical member 120 is disposed between the upper plate 112 and the lower outer plate 113 perpendicularly to the ground. The vertical member 120 has a columnar shape and may be made of stainless steel. As the vertical member 120 of the present invention, a wire or rod can be used. One end of the vertical member 120 is coupled to the lower surface of the upper plate 112 and the other end is coupled to the upper surface of the lower outer plate 113. Here, the vertical member 120 is coupled to the outer bottom plate 113 through the second inlet 114a.

5, the number of the vertical members 120 is increased according to the size of the flow control panel 130. In this embodiment, Or reduced.

The flow regulating panel 130 is provided in the secondary take-in space IS2 inside the duct 110. The flow rate regulating panel 130 faces the inner bottom plate 114 so as to face the ground. The flow control panel 130 is formed with a coupling hole 131 into which the vertical member 120 is inserted and a coupling hole 131 corresponding to each vertical member 120. The flow regulating panel 130 moves upward and downward in the longitudinal direction of the vertical member 120 according to a pressure difference between the outside and the inside of the housing 10 and flows into the inside space PI of the housing 10 through the duct 110. [ .

That is, when there is no pressure difference between the outside and the inside of the housing 10, the flow control panel 130 is seated on the inner bottom plate 114 as shown in FIG. The flow regulating panel 130 moves vertically upward when negative pressure is generated inside the housing 10. The outside air introduced into the primary receiving space IS2 flows into the space between the flow control panel 130 and the inner bottom plate 114 through the second inlet 114a and then flows into the interior space of the housing 10 ).

The flow regulating panel 130 moves along the vertical member 120 while being fitted to the vertical member 120 so that it can move vertically without being moved in the horizontal direction with respect to the ground.

In this embodiment, the flow control panel 130 may be made of an ultra-lightweight material such as a wood block so as to be vertically moved by the negative pressure inside the barn 10.

In the ventilation device 100 of the present invention, the flow rate adjusting panel 130, which is horizontally arranged with respect to the ground, automatically vertically moves by the negative pressure generated inside the barn 10 without a separate driving member, ) To regulate the amount of external air flowing into the inside of the apparatus. The axial ventilation device 100 divides the internal space of the duct 110 into a primary receiving space IS1 and a secondary receiving space IS2 and divides the flow regulating panel 130 into a secondary receiving space IS2). Accordingly, the ventilating apparatus 100 can maintain a constant flow rate of the outside air flowing into the housing 10 for ventilation, and can supply the housing 10 with outside air at a proper flow rate.

The axial ventilator 100 of the present invention may further include an adjusting weight 140 coupled to a lower surface of the flow control panel 130. The adjusting weight 140 adjusts the wind speed of the outside air flowing into the housing 10. That is, as the weight of the adjusting weight 140 is light, the wind speed of the outside air flowing into the housing 10 from the ventilator 100 is reduced. On the other hand, the weight of the adjusting weight 140 increases as the wind speed of the outside air flowing into the housing 10 from the ventilator 100 increases.

In this embodiment, the axial ventilation device 100 has one adjusting weight 140, but the number of the adjusting iron weights 140 may vary according to the size of the flow control panel 130 and the size of the barn 10 Can be increased or decreased.

The wind speed of the outside air supplied from the axial ventilation device 100 to the inside of the housing 10 is adjusted according to the weight and the number of the adjusting weight 140 and the weight of the flow control panel 130. Accordingly, the user adjusts the weight of the flow control panel 130 or the weight of the control weight 140 according to the condition of the barn 10 and the weather to adjust the wind speed of the outside air supplied to the barn 10 from the ventilating apparatus 100 Can be maintained at a proper wind speed.

As described above, the axial ventilator 100 of the present invention can appropriately adjust the air speed of the outside air flowing into the housing 10 by using the adjusting weight 140, The outside air can be sufficiently preheated before reaching the livestock in the barn 10 and the air and the outside air inside the barn 10 can be ideally mixed inside the barn 10. Accordingly, the ventilating apparatus 100 can keep the air inside the housing 10 pleasantly, and can prevent the cold stress and diseases of the domestic animal in the housing 10.

The axial ventilation device 100 may further include a filter net 150 for filtering foreign substances flowing into the duct 110. The filter net 150 is coupled to the outer bottom plate 113 of the duct 110 and is provided corresponding to the first inlet 113a. The filter net 150 filters the foreign matter introduced into the first inlet 113a together with the outside air to prevent foreign matter from entering the inside of the duct 110. [

The axial ventilator 100 further includes a coupling pipe 160 inserted in the coupling hole 131 and coupled to the flow control panel 130. The coupling pipe 160 is formed corresponding to the coupling hole 131, and the vertical member 120 is inserted. At this time, the inner diameter of the coupling pipe 160 is formed to be larger than the thickness of the vertical member 120, thereby minimizing the friction between the coupling pipe 160 and the vertical member 120 when vertically moving the flow control panel 130.

The axial ventilation device 100 further includes a ventilation fan 170 provided inside the housing 10. The ventilation fan 170 adjusts the pressure difference between the inside and the outside of the housing 10 to adjust the vertical movement of the flow control panel 130 vertically. That is, by driving the ventilation fan 170, a negative pressure is formed inside the housing 10, and the flow control panel 130 moves vertically according to the negative pressure formed inside the housing 10.

Hereinafter, an operation procedure for ventilating the interior of the housing 10 using the shaft-use ventilator 100 will be described in detail with reference to the drawings.

FIGS. 7 and 8 are side cross-sectional views showing an operating state of the axial ventilator shown in FIG.

7 and 8, a negative pressure is formed inside the housing 10 by driving the ventilation fan 170 and the flow control panel 130 is moved in the direction of the arrow A in FIG. 7 by the negative pressure formed inside the housing 10 As shown in FIG. Thus, the outside air OA flows into the primary receiving space IS1 through the first inlet 113a and the outside air OA of the primary receiving space IS1 flows through the second inlet 114a into the secondary And enters the dressing space IS2. The outside air OA flowing into the secondary receiving space IS2 flows into the inside space PI of the housing 10 at a constant flow rate and ventilates the air inside the housing 10.

Here, the vertical movement height of the flow control panel 130 is adjusted according to the rotation speed of the ventilation fan 170. When the rotational speed of the ventilation fan 170 rises, the flow regulating panel 130 moves vertically upward. When the rotational speed decreases, the flow regulating panel 130 vertically moves downward. For example, when the rotational speed of the ventilation fan 170 shown in FIG. 7 decreases, the flow regulating panel 130 moves vertically downward as shown in FIG. 8 is larger than the flow rate of the outside air OA flowing into the housing 10 from the axial ventilator 100 of Fig. OA) flow rate is less.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
