BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system using a local negative pressure means,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system by means of a local negative pressure of a house, in which a large-sized supply fan and an exhaust fan are installed facing each other on the left and right sides,

An intake pipe for locally forming a negative pressure on intake pipe by intake; A cyclone separating the foreign matter from the air sucked through the intake pipe by connecting the intake pipe to the inlet; An air pump connected to the outlet of the cyclone to maintain a negative pressure formed around the intake pipe to expand the fresh air region to the negative pressure side; .

According to the present invention, when the air intake pump is disposed on the bottom surface of a housing where a plurality of narrow partitioned poultry or chickens or chickens are housed, that is, a place where odor air is to be removed, The foreign matter and the odor air sucked into the ball are separated by the ciclon, and the air is discharged to the outside, and a reducing pressure is formed around the intake tube, and a fresh air area formed inside the housing by the large air supply fan is negative pressure side Expanded and fresh areas of the livestock can be maintained in a healthy environment.

When large-sized livestock farms are concentrated in an industrial-operated large-scale farmhouse, or when a large number of livestock farms are stacked in a multi-layered structure with a hen coop, the breeding environment of the livestock is not particularly bad, The respiratory disease is so severe that it causes various diseases and the abuse of chemicals for the control has seriously discussed the problem of food contamination,

In the housing, a large-sized supply fan and an exhaust fan are installed on the side wall at a predetermined height so as to supply fresh air to the housing by the supply fan, and the turbid air inside the housing is discharged by the exhaust fan and ventilated .

[Citation 1] No. 10-1260937 (Announcement 2013.05.06) [Reference 2] 10-0952958 (Announcement of Apr. 12, 2010) [Citing Document 3] No. 10-0729180 (June 16, 2007)

Fig. 1 is a distribution diagram of the odor air area and the fresh air area in the interior space of one housing (money yarn). The large air supply fan f1 and the exhaust fan f2 are disposed on the upper left side wall and the upper side wall of the door d of the housing P, And a plurality of partition pig pens (b) are disposed in the bottom layer of the pest (P). The height of our pig is about 1m.

A fresh air area fa formed by the flow of the air supplied by the operation of the air supply fan f1 and the air exhausted by the operation of the exhaust fan f2 And the bottom (B) layer in which the pigs (b) are arranged is not exposed to fresh air, so that the pigs are still in a pollution air area ) pa (dark portion in the figure)

In addition, the poultry poultry manure tank is installed in the bottom of the pig poultry, and odor is continuously rising through the manure trough.

Also, even when chickens or chickens are collectively housed in the bottom B of the house P, the fresh air area fa ventilated by the air supply fan f1 does not reach the floor B of the house Chickens or chickens are still in the stench air area (Pa).

In other words, even if the ventilation performance of the air supply fan and the ventilation fan is good, the fresh air area can be sensed at the eye level of a person, but the fresh air area can not be sensed at the eye level of the domestic animal.

The reason why the fresh air area fa by the air supply fan f1 does not reach the bottom B layer of the housing P as described above is due to the air circulation disorder caused by the structure such as the porcelain usb installed inside the housing However, the fundamental reason is that the flow of air is blocked by the bottom layer (B), and no air flow is formed on the bottom side.

Therefore, the air in the crossflow portion is easily ventilated because airflow is generated between the air supply fan f1 and the exhaust fan f2 by the operation of both fans, but the contaminated odor air in the bottom layer is properly ventilated I will not,

In order to solve the above-mentioned problem, as shown by the arrow in FIG. 2, the present invention forms a local negative pressure toward the bottom of the housing, and is formed by the external discharge of the odor air in the bottom layer and the simultaneous operation of the air supply fan f1 The problem is to allow the fresh air area (fa) to expand uniformly to the bottom (B) layer of the house where the negative pressure is created, so that the livestock can be raised in the fresh air area (fa).

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the present invention in order to solve the above-mentioned problems, it is an object of the present invention to provide an air- And the ventilation system is expanded by a uniform negative pressure distribution system.

It is another object of the present invention to provide an air conditioner which is provided with an intake pipe for generating negative pressure by sucking air in the bottom layer as a means for creating a local negative pressure of the housing and a cyclone separating the foreign matter and air flowing through the intake pipe, And an air pump for sucking air through the ciclon so as to form an air flow toward the bottom by a negative pressure formed around the air intake tube.

It is a further object of the present invention to provide a system and a method for reducing odor air in the bottom layer by means of creating a local negative pressure of the housing, To provide a ventilation system by means of local negative pressure means of the housing, in which the livestock can be raised environmentally friendly in the fresh air area.

The present invention is described in detail as follows.

An intake pipe for locally forming a negative pressure on intake pipe by intake; A cyclone separating the foreign matter from the air sucked through the intake pipe by connecting the intake pipe to the inlet; An air pump connected to an outlet of the cyclone to maintain a negative pressure around the intake pipe to expand the fresh air area of the housing to the negative pressure side; .

In the intake pipe, a plurality of intake holes are perforated at regular intervals, and the size of the intake holes is set in consideration of the uniformity of the suction force depending on the length of the intake pipe. Therefore, as the inner diameter of the intake hole increases toward the outer end of the intake pipe and the inner diameter of the intake pipe increases, the inner diameter of the intake hole becomes smaller.

The length of the suction tube is set according to the structural environment of the housing and can be arranged horizontally close to the bottom of the housing and also vertically and arranged in a narrow low space between corners or structures that are normally not ventilated That is, the intake pipe is installed at a local site where air is to be exhausted.

Between the suction pipe and the inflow port of the cyclone, a connection pipe or a flexible pipe is connected according to the condition of the installation site.

Generally, it is preferable that the ciclon and the air pump are installed outside the housing, considering the space inside the housing and the noise of the air pump.

The air pump can be replaced with a motor fan, and the cyclone dust collecting box can be easily separated and cleaned.

The discharge pipe of the air pump coupled to the outlet of the cyclone may be blown to the side of the odor air dilution device to dilute the odor and discharge it to the atmosphere.

According to the present invention having the above-described configuration, in a housing where a large-sized supply fan and an exhaust fan are installed facing both side walls and ventilated, a plurality of small partitioned porcine worms, or chicks or chickens, The intake pipe is disposed at the bottom of the bottom between the bottom of the housing or various fixtures obstructing the ventilation.

In particular, when chickens or chickens are raised in a group on the bottom of a barn, one or a plurality of low-level horizontal intake motors capable of sucking contaminated air in the bottom layer of the central part of the barn are arranged side by side at predetermined intervals .

In addition, in the case of the partitioned pork, each of the pigs is placed along the side wall of the pig's pancreas so as to pass through the floor adjacent to the pancreas or the abdominal cavity so that a part of the pancake is introduced into the inside of the panty tank, The intake tract is disposed at a height that can suck the odor air on the upper side of our manure tank and the odor air on the upper side of the pigs and pigs.

In addition, the space between the structure and the installation is staggered, and the intake pipe is disposed in a zigzag manner by using a bending pipe, so that odor air can be discharged.

As a result, the arrangement of the suction pipe is arranged such that a fresh air region formed in the inner space of the housing by the operation of the air supply fan is expanded to the bottom corner of the housing, .

When the arrangement of the intake pipes is completed, the air pump is operated.

In order to prevent the problem that the viscous material of the livestock adheres to the rotary shaft of the air pump to cause the rotation failure, the air pump is disposed on the side of the inlet of the cyclone, Respectively.

When the air pump is operated, the internal pressure of the ciclon is lowered, so that a low pressure is generated around the suction hole of the suction pipe, so that the contaminated odor air in the bottom layer of the housing is sucked into the suction hole of the suction pipe.

The contaminated odor air and foreign substances which are sucked through the intake holes of the intake pipe, such as the vacuum cleaner, are introduced into the cyclone through the conduit, so that the foreign matter is separated by the cyclone and the air is discharged to the outside through the outlet of the air pump. A new airflow is formed in the internal space of the housing by the negative pressure formed around the intake air holes of the intake tube toward the intake air holes of the intake tubes arranged on the bottom side.

Therefore, the fresh air region formed inside the housing by the air supply fan along the bottom side air current formed by the negative pressure formed around the intake tube extends to the bottom floor corner of the housing.

On the floor of the house where the chickens or chickens are kept, the stench is severely emitted by the excrement. However, odor air containing ammonia, nitrogen, or carbon dioxide (CO ₂ ) The fresh air is continuously supplied to the bottom floor of the barn, so that the air inside the barn is kept fresh,

In addition, in the case of pigs, the odor air ascending from the pit tank is sucked through the intake hole of the suction pipe of the part of the suction pipe introduced into the upper side of the pit tank, and the odor air inside the pigs is sucked into the suction pipe of the suction pipe And the upper air of the pig is sucked into the suction hole of the suction pipe leading to the upper side of the pig, the air flow from the space of the concurrent housing to the suction pipe of the pig is formed, and the fresh air supplied by the large- Because it is supplied to us, pigs are more eco-friendly in the fresh air area when their odors are further reduced.

Accordingly, not only the functional efficiency of the large supply fan and the exhaust fan disposed in the housing is further improved, but also the fresh air area is extended to the corner of the bottom floor by the air flow formed on the sea side of the house by the simple negative pressure means of the present invention. The livestock can be raised in a cleaner environment than in the pond.

Since a negative pressure is locally generated in the bottom layer of the housing where the flow of air is blocked, airflow can be formed toward the bottom, so that the fresh air area formed by the operation of the air supply fan can reach the bottom floor corner It can be expanded to a uniform distribution.

A suction pipe for sucking air in the bottom layer by a means for creating a local negative pressure of the housing, a ciclon for separating the air and the foreign matter introduced through the suction pipe, And an air pump that sucks air through the ciclon so that an airflow is formed toward the bottom by the negative pressure formed around the cushion. Therefore, the structure is simple and easy to install and use. By arranging the intake tracts, it is possible to easily remove the contaminated odor air such as the vacuum cleaner, and simultaneously, fresh air can be locally induced.

Also, all the space leading to the bottom of the stall can be ventilated with fresh air, so that livestock can be raised in an environmentally friendly manner in a fresh air area.

Further, the present invention has various effects such as being usefully applied to local ventilation means of various industries.

Fig. 4 is an example of applying the local negative pressure means M of the present invention to a pig (b) partitioned into several compartments in a barn (P).

4, in the case of the pig worm b having the structure shown in Fig. 4, the cyclone 20 and the air pump 30 are connected to the outer side of the poultry P of the pig worm b, Respectively.

The outer end portion 10a of one or more bottom intake tubes 10 penetrating through the lower portion of the stool of the pig we b or the bottom B adjoining the stool serves as the pouring tank t of the pig, And the suction pipe 10 is guided to the upper side of the pig worm b along the side wall w of the housing to be fixed by the fixture c vertically and the inner end of the suction pipe 10 Is connected to the inlet 21 of the ciclon 20 by passing through the side wall w of the housing by means of a flexible connecting tube or conduit 12 and a bending tube 11 connected to the cigarette 10b.

Since the ciclon 20 and the air pump 30 are integrally coupled to each other, there is no separate installation operation. When the discharge pipe 14 of the air pump 30 is connected to a malodor air dilution device You can do piping work.

When the air pump 30 is operated by the motor 30m, the air inside the ciclon 20 is sucked, and the contaminated odor air around the suction pipe 10h is sucked into the duct 12 and the air introduced into the ciclon 20 is separated from the air and the foreign matter is collected in the dust box 24 through the dust collecting opening 23 and separated The air is introduced into the inlet 31 of the air pump 30 through the conduit 13 connected to the outlet 22 of the ciclon 20 and discharged to the outlet 32 of the air pump 30 and the outlet 14 of the air pump 30. [ As shown in FIG.

Since the malodor air is sucked continuously into the intake holes 10h of the intake tract 10 in accordance with the continuous operation of the air pump 30, a negative pressure is created around the intake tract 10,

As a negative pressure is formed around the intake pipe 10, a flow of air that has not been generated in the direction from the space inside the housing P to the intake hole 10a of the intake pipe 10 is formed. The local negative pressure lasts while the air pump is operated and air is sucked into the suction hole 10h of the suction pipe 10,

Therefore, the odor air generated in the pig (b) is sucked into the suction hole (10h) of the suction pipe (10) together with the fresh air flowing along the air flow and is discharged to the outside. Since the pig is filled with fresh air, Unlike ours, pigs (b) are placed in the fresh air zone (fa) so that pigs can be raised in an environmentally friendly and healthy way in the fresh air zone.

Fig. 5 is an embodiment in which the negative pressure means of the present invention is applied to a poultry house housing

As shown in Fig. 5, when a chick is placed on the bottom of the house (b) of the poultry or when the chicken is irradiated, the crocons (20) and air The pump 30 is installed.

The intake tube 10 for sucking air is horizontally arranged at a level lower than at least the height of a chick or chicken on the bottom of the barn B and is fixed with a fixture c.

One or a plurality of suction pipes 10 are arranged in parallel at predetermined intervals according to the planar width and width of the housing.

Also, when the suction pipe 10 is disposed in a local space according to an unillustrated installation or structure provided on the housing bottom B, it is piped using a conduit or a curved pipe in a form suitable for each installation environment.

A curved pipe 11 and a conduit 12 connected to the inner end portion 10b side of the suction pipe 10 disposed at the bottom B of the housing b are provided on the outside of the housing through the side wall w of the housing Is connected to the inlet (21) of the cyclone (20)

When the air pump 30 is operated by the motor 30m, the internal air of the ciclon 20 is sucked in. Then, the contaminated odor air of the bottom floor of the housing is introduced into the intake hole 10h of the intake tube 10 first Sucked,

Air containing foreign matter sucked through the intake pipe 10 flows into the cyclone 20 through the inlet 21 through the conduit 12.

The air introduced into the cyclone 20 is separated from the foreign matter and is collected in the dust box 24 through the dust collector 23 and separated air is discharged through the outlet 22 of the cyclone 20 and the conduit 13 Is discharged to the discharge port (32) and the discharge pipe (14) through the air pump (30).

Since the malfunctioning air is continuously sucked into the intake holes 10h of the intake tract 10 in accordance with the continuous operation of the air pump 30, a negative pressure is created around the intake tract 10,

As the negative pressure is formed around the intake pipe 10, a flow of air is generated in a direction from the space inside the housing P to the intake hole 10a of the intake pipe 10. The local negative pressure lasts while the air pump is operated and air is sucked into the suction hole 10h of the suction pipe 10,

As shown by the arrow in Fig. 2, since the air supply fan f1 and the air discharge fan f2 provided in the housing P are operated, fresh fresh air introduced into the interior of the housing is supplied to the bottom B of the poultry house housing, The fresh air area fa formed inside the housing is extended to the corner of the bottom B of the poultry housing b.

Therefore, the odor air generated by the excretion of the poultry house generated at the bottom of the poultry house is sucked into the suction hole (10h) of the suction pipe (10) together with some fresh air flowing along the air stream, Unlike conventional poultry houses, chickens or chickens are placed in the fresh air area (fa) because they are filled with fresh air, so that they can be eco-friendly and healthy.

In addition, although the present invention has been described with respect to a ventilation system for a house, it is also applicable to local ventilation means of various industries.
