Description

  The embodiment of the present invention relates to a chicken breeding apparatus equipped with air conditioning equipment so that a large number of chickens can be raised in a comfortable environment.

  2. Description of the Related Art Conventionally, many [Patent Documents] have been provided in consideration of chicken breeding devices that can be bred while maintaining the health of a large number of chickens and that can efficiently collect eggs. Since chickens are vulnerable to high temperatures, temperature management (cooling) is important for breeding in high-density poultry houses.

  For example, a poultry house equipped with a cooling facility shown in [Patent Document 1] is designed to spray a large amount of water on a cold water filter provided at one end of the building to vaporize it and cool the inside of the poultry house with the heat of vaporization. . The air after cooling the poultry house is forcibly exhausted from the building by a forced exhaust fan provided at the other end of the building. The cold water filter has a mesh shape and includes a large number of air gaps so that air can pass therethrough.

Japanese Patent Laid-Open No. 9-135648

  In order to collect eggs, it is necessary to arrange chickens in a row in the poultry house. In addition, if a larger amount of chickens is bred to reduce production costs, the poultry house becomes longer in the longitudinal direction. Therefore, even if the temperature is lowered by several degrees from the outside air temperature with the cold water filter, there is a possibility that the whole inside the chicken house cannot be sufficiently cooled by heat radiated from a large number of chickens.

  Moreover, at present, considering the efficient use of the egg collection conveyor, for example, it has a structure in which a plurality of chicken houses that are long in the longitudinal direction are arranged in parallel. If it is going to introduce the air conditioner which completely cools and heats the inside of a poultry house, an indoor unit will be installed in each building at predetermined intervals along the longitudinal direction. On the other hand, when outdoor units are provided at the same place in a lump, connection piping work with each indoor unit becomes complicated.

  Because of these circumstances, a larger number of chickens can be bred vigorously in a more comfortable environment, and they are not affected even in extreme heat, improving spawning efficiency and contributing to a reduction in production costs. A chicken breeding device was desired.

The chicken breeding apparatus according to the present embodiment includes a plurality of chicken house buildings that are long in the longitudinal direction and whose interior is partitioned into a wind guide chamber and a return duct chamber by a partition plate along the longitudinal direction.
The breeding block is arranged in a wind guide room of a plurality of poultry house ridges, and rearing gauges for accommodating a large number of chickens are arranged in the longitudinal direction along the wind guide room.
One air conditioner building is connected to one end of each of a plurality of poultry house buildings, sucks back heat exchange air from the return duct chamber, exchanges heat, and replaces it with temperature-controlled cold or warm heat exchange air. Blow out into the wind chamber.
A bent duct portion connecting the air guide chamber and the return duct chamber is provided at each of the other ends of the plurality of poultry houses, and guides the heat exchange air that has passed through the air guide chamber to the return duct chamber.

A guide plate 16 is provided along the lower part of the disinfecting spray nozzle 15 to concentrate and guide the disinfecting liquid. A drain pan 17 is provided at the bottom of the central air conditioner tower 1. The disinfectant received by the drain pan 17 is discharged through a guide pipe to a discharge tank (not shown) disposed outside the tower.

  The main header ridge 3 is divided into an upper part and a lower part of the first floor part and the second floor part by a partition plate 18. As described above, one end of the main header ridge 3 is connected to the central air conditioner tower 1, and the other end shown in FIG. 1 is closed and the ventilation damper 2 is provided.

  In the example of FIG. 2, the indoor unit 25 is arranged in the main header ridge 3, but by considering the arrangement of the disinfecting spray nozzle 15 and the drain pan 17, together with the prefilter group 23 and the HEPA filter group 24, The indoor unit 25 composed of the indoor heat exchanger 26 and the indoor blower 27 can be completely accommodated in the central air conditioner tower 1.

  The main return air duct 21 which is the second floor portion of the main header building 3 is provided with a ventilation fan 28 for blowing heat exchange air guided to the central air conditioner tower 1 as described later, and a carbon dioxide removing device. 29 is arranged. Although the ventilation fan 28 is always driven, the carbon dioxide removal device 29 is operated as a prevention device in the case of a bird flu epidemic.

  Although not particularly illustrated, a dust collector or a dust collector may be disposed in the main return air duct 21 of the main header building 3. By operating these devices, “contaminants” composed of feathers, chicken feed, or chicken dung can be efficiently removed from the air passing through the main return duct 21.

  Furthermore, an electric seat shutter may be provided at a connection portion between the main header building 3 and the central air conditioner tower 1. Central control unit tower 1, main header building 3 and each chicken house building 4 can be completely separated by control in the control room for the electric seat shutter, and each poultry house building 4 is completely in positive pressure by adjusting the opening. (Internal pressure should be higher than outdoor pressure).

  The indoor blower 27 of the indoor unit 25 has a high static pressure characteristic, but when the HEPA filter group 24 having a large ventilation resistance is used, the number of revolutions is increased by using an inverter or the like. It becomes possible to secure a predetermined air volume.

FIG. 3A is a view in which the main header ridge 3 is a longitudinal section, and one poultry house ridge 4 is partially cut away. FIG. 3B is a longitudinal sectional view of one poultry house ridge 4 taken along the line BB of FIG. 3A, and illustrates the internal structure and the flow of heat exchange air.
In the figure, the x mark in the circle indicates that the heat exchange air flows from the front side to the back side of the paper, and the black circle mark in the center of the circle indicates that the heat exchange air flows from the back side of the paper to the near side. .

  As described above, the inside of the main header ridge 3 is partitioned up and down by the partition plate 18 serving as the floor of the second floor portion by the ceiling of the first floor portion, and there is no window in either the first floor portion or the second floor portion. The first floor portion is a main air duct 20, and the second floor portion is formed as a main return air duct 21.

A plurality of poultry house ridges 4 are connected to one main header ridge 3, and the interior of each hen house ridge 4 is partitioned vertically by a partition plate 30 provided at the same height as the partition plate 18 of the main header ridge 3 It is done. The first floor portion that is the lower part of the partition plate 30 in the poultry house building 4 is referred to as a “wind guide chamber” 31, and the second floor portion that is the upper portion of the partition plate 30 is referred to as a “return duct chamber” 32.
There is no vertical partition in the connection part between one main header building 3 and each chicken house building 4, and the main air duct 20 of the main header building 3 and the air guide chamber 31 of each chicken house building 4 communicate with each other, Similarly, the main return air guide path 21 of the main header building 3 and the return duct chamber 32 of each poultry building 4 communicate with each other.

  A plurality of rearing blocks GA in which rearing gauges G that house a large number of chickens are stacked in multiple stages are housed in the air guide chamber 31 of the poultry building 4 in a state of being arranged in the longitudinal direction of the air guide chamber 31. Although not particularly illustrated, the air guide chamber 31 is provided with an egg collection conveyor, a water supply / drainage device, and a feces treatment conveyor, and all of these utility management can be integrated and controlled in the control room.

  The main air duct 20 of the main header building 3 does not have a breeding block GA, and is connected to the egg collection conveyor, water supply / drainage device, and feces processing conveyor of each poultry building 4 and the main egg collection conveyor and the main water supply / drainage device not shown. , Feces main processing conveyor is provided. All of these utility management can be centrally controlled in the control room, saving labor.

  As shown to FIG. 3 (A), the bending duct part 5 mentioned above is connected to the edge part on the opposite side to the site | part connected with the main header ridge 3 in each chicken house ridge 4. As shown in FIG. The bent duct portion 5 is bent so as to communicate the air guide chamber 31 which is the first floor portion of the poultry house building and the return duct chamber 32 which is the second floor portion. In particular, as shown in FIG. 1, a ventilation damper 33 is provided on the side wall of the bent duct portion 5.

  As described above, the central air conditioner tower 1 is provided with the outside air intake damper 10, and the main header ridge 3 and each poultry house ridge 4 have a windowless structure without windows. Further, a ventilation damper 2 is provided at the end of the main header ridge 3 so as to be openable and closable, and a ventilation damper 33 is provided at the bent duct portion 5 so as to be openable and closable.

  From this, the main header ridge 3 and each poultry house ridge 4 sealed each damper 10, 2, 33 or controlled the opening, and further driven the air conditioner 6 to increase the internal pressure from the outside. It can be a “positive pressure type”. The intake of the air from the outside is only the intake of the outside air of the central air conditioner tower 1, and the air that does not pass through the prefilter group 23 and the HEPA filter group 24 can be prevented from directly entering each poultry house building 4.

FIG. 4 is a plan view of the chicken breeding apparatus KA, which partially shows the flow of heat exchange air.
The heat exchange air guided from the main air duct 20 to the branch section between the main air duct 20 of the main header building 3 and the air guide chamber 31 of each chicken house building 4 is efficiently sent to the air guide chamber 31 of each chicken house building 4. A heat exchange air guide plate 35 is provided for well distributing and guiding.

  As shown in FIGS. 2 to 4, heat exchange air (CA), which is cold air or warm air generated by the air conditioner 6 in the central air conditioner tower 1, is sent to the main air duct 20 of the main header building 3. Be blown out. Further, the heat exchange air is diverted and guided by the heat exchange air guide plate 35 to the wind guide chambers 31 of the respective chicken house ridges 4 to cool or heat the chickens in the breeding gauge G disposed in the wind guide chamber 31.

  The heat exchange air that has come out of the air guide chamber 31 is guided as return air (RA) from the bent duct portion 5 to the return duct chamber 32 of each poultry house building 4. Therefore, an opposing flow partitioned by the partition plate 30 is formed in each poultry house building 4.

  The return air guided through the return duct chamber 32 of each poultry building 4 collects in the main return air duct 21 of the main header building 3. Also in the main header ridge 3, a counter flow partitioned by the partition plate 18 is formed and sucked into the air conditioner 6 from the main return air guide path 21. Then, heat is again exchanged by the indoor heat exchanger 26, and heat exchange air such as cold air or warm air is blown out to the main air passage 20.

  Eventually, in this chicken breeding apparatus KA, heat exchange air is guided from one central air conditioner tower 1 through a plurality of poultry house buildings 4 in a loop through one main header building 3. . Therefore, there is no problem of air stagnation and temperature distribution non-uniformity as in the distributed batch type air conditioning ventilation that air-conditions a plurality of poultry houses distributed as in the past. An air conditioning distribution close to a uniform flow can be obtained and air conditioning efficiency can be improved.

  The inside of the poultry house ridge 4 was partitioned into a first-floor air guide chamber 31 and a second-floor return duct chamber 32 through a partition plate 30 that vertically divides the interior, and heat exchange air was allowed to flow through the chambers 31 and 32. Therefore, it is possible to insulate the solar radiation load with the flow of return air guided to the return duct chamber 32 on the second floor. It is not necessary to thicken the heat insulating material to be constructed in the attic of the poultry house building 4 and the construction cost can be reduced.

  On extremely hot days when the outside air temperature becomes extremely high (for example, 35 ° C. or higher), all the dampers 2, 10, 33 are closed to prevent an increase in heat load due to the outside air, and the air conditioner 6 performs the cooling operation. That is, cold air is blown out from the indoor unit 25 and is diverted to the air guide chambers 31 of the respective poultry building 4 through the main air duct 20 of the main header building 3.

  Since the breeding gauge G in which a large number of chickens are housed is arranged in the wind guide chamber 31 of each chicken house building 4, the cold air cools the chickens in the breeding gauge G. Thereby, the lethal temperature (about 40 degreeC) or less of a chicken is ensured and a severe heat damage can be avoided.

  When the outside temperature falls below freezing, chickens slow down to maintain body temperature, thus reducing feed intake. So-called feed efficiency is reduced and thus egg-laying efficiency is reduced. At this time, all the dampers 2, 10, 33 are closed, and the air conditioner 6 is switched to the heating operation.

  Warm air is blown out to the air guide chamber 31 of each chicken house building 4 through the main air passage 20 of the main header building 3 to warm the chickens in the breeding gauge G. Therefore, the optimal temperature (about 13 degreeC) for a chicken can be ensured and egg-laying efficiency can be maintained at the same level as usual.

  In a warm region, the outside air temperature does not decrease so much and the heat generated by a large number of chickens also contributes to heating the chicken house building 4. In such an area, the air conditioner 6 may be used exclusively for cooling.

FIG. 5 is a diagram illustrating the operation of the units constituting the chicken breeding apparatus during normal times and during avian influenza (disease) epidemic.
During normal times, the HEPA filter 24 is removed and the outside air is not washed. The temperature of the breeding cage GA is managed, and the air conditioner 6 stops the operation of the refrigeration cycle and performs the air blowing operation for operating only the indoor air blower 27 at 13 ° C. which is the optimum temperature for the chicken and the temperatures before and after that. The intake fan 12 is driven, and the dampers 2, 10, 33 are fully opened.
In addition, when the temperature falls a few degrees below the optimum temperature, the air conditioner 6 performs the heating operation, and the intake fan 12 stops. Each of the dampers 2, 10, and 33 changes from a half-open state to a fully-closed state.

On the other hand, when the temperature rises several degrees from the optimum temperature, the air conditioner 6 switches to a weak cooling operation. Each of the dampers 2, 10, and 33 changes from a half-open state to a fully-closed state. The operation change temperatures of the respective devices are different from each other as shown in FIG. In any of these states, the carbon dioxide removal device 29 does not operate. On the other hand, when a viral avian disease such as avian influenza is prevalent, the HEPA filter 24 is additionally incorporated and a disinfectant is sprayed. The operations of the air conditioner 6 and the intake fan 12 may be basically the same as in normal times, but the operation switching temperatures of the devices are slightly different as shown in FIG.

  Each of the dampers 2, 10, and 33 is in a half-open state near the optimum temperature, and is switched to a fully closed position when the temperature falls a few degrees below the optimum temperature, and is switched to a fully closed position when the temperature rises a few degrees above the optimum temperature. The carbon dioxide removal device 29 is stopped in the vicinity of the optimum temperature, but starts to operate when the temperature falls several degrees below the optimum temperature, and also starts when the temperature rises several degrees above the optimum temperature.

  In this way, during the bird disease epidemic, the outside air inflow is reduced or completely blocked, and the outside air already taken into the central air conditioner tower 1 is sterilized. As a result, the chicken housed in the breeding gauge G can be prevented from being attacked by the virus, and an ideal prevention mode can be realized.

6A and 6B are plan views of modified chicken breeding apparatuses KA1 and KA2, each having a structure different from that of the chicken breeding apparatus KA described above with reference to FIG.
The chicken house building 4 described above is formed in the same length, but is not limited to this. As shown in FIG. 6A, the chicken house building 4A is connected to the central air conditioner tower 1. The length in the longitudinal direction is gradually shortened as the distance from the near part increases.

  That is, the main header ridge 3 has a duct structure with respect to the central air conditioner tower 1, and each chicken house ridge 4A also has a duct structure. If the size and direction (and angle) of the heat exchange air guide plate 35 that distributes heat exchange air from the main header building 3 to each chicken building 4 are not properly installed, the amount of the chicken building 4A close to the central air conditioner tower 1 is as large as The more heat exchange air flows, the smaller the heat exchange air becomes.

  In FIG. 4, the size of the heat exchange air guide plate 35 is increased in order from the side closer to the central air conditioner tower 1 to the side farther away. Such setting of the size and angle of the heat exchange air guide plate 35 must be set in accordance with each of the poultry houses 4 and is difficult.

  Therefore, in FIG. 6 (A), each poultry house building 4A and the central air conditioner tower are formed so that each of the poultry house buildings 4A is formed so that the length in the longitudinal direction is gradually shortened as the distance from the part close to the central air conditioner tower 1 increases. By making the distances in the flow of heat exchange air performed with 1 as equal as possible, the heat exchange air was distributed almost in the same state to every corner of each poultry house building 4A.

  In FIG. 6B, in the same manner as in FIG. 6A described above, each poultry house ridge 4B is formed such that the length in the longitudinal direction is gradually shortened as the distance from the portion close to the central air conditioner tower 1 increases. The longitudinal direction of each poultry house ridge 4B was connected to the main header ridge 3 in a state where it was tilted by a predetermined angle so that the flow of heat exchange air between the main air duct 20 and the air guide chamber 31 formed an obtuse angle.

  Thereby, the heat exchange air led from the central air conditioner tower 1 to the main air duct 20 of the main header ridge 3 can be efficiently diverted to the baffle chambers 31 of the respective poultry house ridges 4 with little resistance. Then, the return heat exchange air guided from the bent duct portion 5 to the return duct chamber 32 can be efficiently guided to the main return air guide path 21 of the main header ridge 3 with little resistance.

  FIG. 7A is an external perspective view of the chicken breeding apparatus KB in the second embodiment, and FIG. 7B is a cross-sectional plan view of the central air conditioner tower 1B of the same embodiment. In this embodiment, the air conditioner building is configured only from the central air conditioner tower 1B.

  Here, the central air conditioner tower 1B has a polygonal shape (a pentagonal shape in the example of FIG. 7) in plan view. The main header building 3 as described above is unnecessary, and the plurality of chicken building 4C is directly connected to each surface of the central air conditioner tower 1B. In other words, the number of the poultry house ridges 4 is provided according to the polygonal shape of the central air conditioner tower 1B, and it is neither more nor less.

  Inside the central air conditioner tower 1B, indoor units are arranged, and an outdoor unit 8 is arranged on the roof, and the air conditioner 6 is constituted by these units. Further, a ventilation window 9 as described with reference to FIG. 2 is fitted, an outside air intake damper is provided inside, and a wire net for preventing small animal intrusion is stretched. Similarly, a plurality of intake fans are attached, an annular disinfection spray nozzle is provided, and a drain pan is provided at the bottom.

FIG. 8 is a longitudinal sectional view of each chicken house ridge 4C.
Each poultry house ridge 4C is a windless, but has a one-story structure with a high ceiling (roof). The outer wall such as the side walls and the ceiling wall (roof) can be a so-called prefabricated building mainly made of inexpensive lightweight steel. The partition plate 30B that divides the building into two layers is provided with a predetermined gap between the side wall and the ceiling wall. That is, each chicken house ridge 4C has a double structure in which a building is provided inside the prefab building.

  The cross section of the poultry house ridge 4C is from the air guide chamber 31B (inner building) inside the partition plate 30B and the return duct chamber 32B formed in the gap between the outside of the partition plate 30B and both side walls and the ceiling wall which are the outer walls of the building. Become.

  Each of the cross-sectional shapes is such that the air guide chamber 31B is rectangular, whereas the return duct chamber 32B is formed in a concave shape that is inverted up and down. One end of each of the air guide chamber 31B and the return duct chamber 32B is connected to the central air conditioner tower 1B, and the other end is in communication with the bent duct portion 5. In the air guide chamber 31B, there is no change in that a breeding block GA in which breeding gauges G accommodating a large number of chickens are arranged along the longitudinal direction is arranged.

  Since the number of poultry house ridges 4C is the same as the number of faces of central air conditioner tower 1B, it is convenient to apply as a small-scale chicken breeding apparatus KB. The breeding block GA in which breeding gauges G for accommodating chickens are arranged is surrounded by a double structure of the outer wall of the chicken house building 4C and the partition plate 30B, so that it is hardly affected by the outside air temperature, and a complete air conditioning effect can be obtained. .

  The chicken house ridges 4, 4A, 4B, and 4C in the first and second embodiments are assumed to be medium-sized with a length of about 25M. Therefore, if a certain amount of static pressure is obtained, the indoor blower 27 has no fear of temperature change and air volume change during supply to the poultry house ridges 4, 4A, 4B, and 4C. As a precaution, a booster fan may be provided in the main return air duct 21 or the return duct chamber 32 so that the return heat exchange air is accelerated and guided.

  In addition, the poultry house building 4C divided by the partition plate 30B inside with such a one-story structure is not limited to being connected to each surface of the polygonal central air conditioner tower 1B as shown in FIG. As shown in FIG. 1, the main air conditioner tower 1 and the main header ridge 3 may be connected in a substantially fish-bone shape. Of course, at this time, the main header building 3 has a structure adapted to the chicken building 4C.

  Conversely, the poultry house building 4 shown in FIG. 3 may be connected to each surface of a polygonal central air conditioner tower 1B as shown in FIG. Also in this case, it is necessary to set it as the internal structure of the central air conditioner tower 1B adapted to the structure of the poultry house building 4.

  As mentioned above, although this embodiment was described, the above-mentioned embodiment is shown as an example and does not intend limiting the range of embodiment. The novel embodiment can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the scope of the invention.
