Description
Technical field
The present invention relates to the broiler breeding field of livestock breeding, be specifically related to a kind of modernization hen house.
Background technology
In modernization broiler breeding technology, the environmental control system of hen house is most important, relate to the many factors such as temperature, humidity, wind speed, illumination, air quality, the key of hen house ring control is temperature control, and ventilating is in general one of basic means of controlling hen house temperature.
Although the method for ventilation that Various Seasonal adopts is had nothing in common with each other, but the major function of ventilating system comprises ventilation and cooling, for example winter ventilation Main Function is ventilation, in time the pernicious gases such as the ammonia in hen house, suspension and carbon monoxide are discharged, summer ventilation Main Function is cooling, by guaranteeing that the ventilation of certain wind speed causes air-cooled effect, make chicken reach relatively comfortable sendible temperature, guarantee its normal growth.
The more employing of summer ventilation " wet curtain-negative-pressure air fan " aeration cooling system, the operation principle of this aeration cooling system is now described in conjunction with Fig. 1, this aeration cooling system is comprised of wet curtain 11, water supply installation 12, exhaust blower 13, wherein, wet curtain 11 is arranged in the ventilating opening being opened on hen house one body of wall, water supply installation 12 is arranged at the upper end of wet curtain 11, this system comprises main-supply and is provided with the distributive pipe road that adds wet hole, and exhaust blower 13 is installed in the through hole with on the wet relative body of wall of curtain 11 of papery porous.
When the ventilating opening of the wet curtain of opening installation, while opening exhaust blower, the air stream of hen house outside when porous, moistening wet curtain surface, large quantity of moisture evaporation, the sensible heat being embodied by temperature in air is converted into evaporation latent heat, thereby reduces the temperature of air self.Indoor by constantly introducing in a steady stream through the cold air of Wet-curtain temperature reducing during exhaust blower exhausting, and the indoor relatively hot air after heat exchange is discharged hen house by exhaust blower, thus reach cooling-down effect.In addition, this method can also play to hen house the effect of humidification.
At present, in broiler breeding in order to obtain best production achievement, the emphasis Consideration of conventionally controlling sendible temperature as environment of chicken house, rather than dry-bulb temperature.Sendible temperature is to weigh chicken to feel the leading indicator of environmental temperature height, it and dry-bulb temperature, relative moisture, wind speed be functional relation, referring to the function reference table shown in table 1.
Table 1
| Dry-bulb temperature | Relative moisture | Wind speed | Sendible temperature |
| 80F(27℃) | 50％ | 0 | 82F(28℃) |
| 80F(27℃) | 70％ | 0 | 86F(30℃) |
| 80F(27℃) | 50％ | 2m/s | 66F(19℃) |
| 80F(27℃) | 70％ | 2m/s | 70F(21℃) |
As shown in Table 1, under identical dry-bulb temperature and identical wind speed, the higher sendible temperature of relative moisture is higher, and relative moisture increases by 20% sendible temperature will increase by 2 ℃; Under identical dry-bulb temperature and identical relative moisture, because the higher sendible temperature of effect wind speed of air-cooled effect is lower, when wind speed increases 2m/s, sendible temperature will reduce by 9 ℃, and as can be seen here, wind speed is more obvious to reducing the effect of sendible temperature.
Based on These characteristics, in order to obtain the sendible temperature of suitable chicken growth, the mean wind speed in hen house at least should reach more than 2 meters.And mean wind speed is relevant with hen house sectional area to total ventilation in hen house, the relation between three is as shown in formula (1):
formula (1)
Wherein, the mean wind speed of υ on representing in hen house along wet curtain to exhaust blower direction; N represents the quantity of exhaust blower;
represent the exhaust air rate of every exhaust blower; S represents the sectional area of hen house.
Formula clearly illustrates that in (1) very much, wants to improve the wind speed of hen house, or increases total ventilation of hen house, increases row's exhaust blower quantity, or reduces the sectional area of hen house.Increase row's exhaust blower quantity and mean increase cost, power consumption and maintenance cost.Therefore,, generally in order to control cost, generally from reducing sectional area aspect, consider.
Next, by reducing the sectional area of the hen house of a certain designated volume, be example, describe the relation between three in detail.As shown in Figure 2, the cross sectional shape of a hen house consists of rectangle and isosceles triangle, and wherein, the width of rectangle is 12 meters, and height is 2.4m; Leg-of-mutton height is 2.4m, sectional area s=43.2mm
2.Platform exhaust blower is installed in hen house, and the exhaust air rate hypothesis of every exhaust blower is 9m
3/ s, calculates above-mentioned parameter substitution formula (1):
In order to reduce the sectional area of the hen house parts 2 that keep out the wind that suspended at hen house top, parts 2 to the height of hen house bottom surface that keeps out the wind is 3.6m, other parameter constants, now, sectional area s=39.6mm
2, the wind speed υ ≈ 2.27m/s drawing by formula (1).
In the situation that row's exhaust blower quantity is constant, by reducing hen house sectional area, wind speed can be improved to 0.27 meter per second on original basis.The air-cooled effect that wind speed produces after changing is also different, and the corresponding temperature of both air-cooled effects differs approximately 2 ℃, and in thermal extremes situation, 2 ℃ of temperature difference are enough to chicken group to cause serious injury.
As can be seen here, summer is during longitudinal ventilation, and in hen house, installing keeping out the wind holds court from behind a screen and really the wind speed and the cooling-down effect that improve in hen house are had to positive effect.But deep bead can only be to helping out in hen house, and should be as the Main Means that improves wind speed.But in practical application, people are by the distance between hen house bottom surface and deep bead of dwindling simply, to obtaining relatively high wind speed, but the wind speed that this method will be aggravated in hen house is inhomogeneous, and makes the level of growth of chicken unbalanced, finally will cause the reduction of overall yield.

Embodiment
Core of the present invention is, provide a kind of modernization hen house that is provided with the parts that keep out the wind, by setting hen house bottom surface to the distance of deep bead, so that wind speed is uniformly distributed relatively in hen house, thereby make chicken level of growth equilibrium in hen house, finally realize the raising of overall yield.
Without loss of generality, now in conjunction with Figure of description, illustrate present embodiment.
Refer to Fig. 1 and Fig. 2, Fig. 1 is the schematic perspective view of hen house in prior art, and Fig. 2 is the schematic cross-section of hen house mounting block wind part in Fig. 1.
As shown in Figure 2, a kind of modernization hen house provided by the invention, comprise and be installed on the wet curtain 11 in ventilating opening on hen house one side wall, be arranged at the water supply installation 12 of wet curtain upper end, and be arranged at least one exhaust blower 13 on another side wall, also comprise at least one parts 2 that keep out the wind that is suspended in hen house top, 2 distance L from described hen house bottom surface of windshied part.
formula (2)
Wherein, n represents the quantity of exhaust blower 13,
represent the exhaust air rate of every exhaust blower 13, υ represents the mean wind speed in hen house, and w represents in the parts place plane of keeping out the wind, the distance between two relative bodies of wall, and h represents the height of body of wall.
Compared with prior art, the present invention is clear and definite by formula, in the hen house of designated volume, while obtaining the sendible temperature of suitable chicken growth during required mean wind speed, the parts that keep out the wind, from the distance of hen house bottom surface, have solved in prior art in order to obtain higher wind, dwindle simply between the two distance and cause the inhomogeneous problem of wind speed in hen house, thereby make in hen house wind speed relatively even, the level of growth of balanced chicken, finally provides the output of chicken.
Next, by three concrete instances, illustrate, by formula (2) how to confirm, keep out the wind parts to the appropriate distance between hen house bottom surface.
Example 1: as depicted in figs. 1 and 2, the cross sectional shape of A hen house is comprised of rectangle and triangle, suppose that we wish by mounting block wind part, make the mean wind speed in hen house reach 2.5m/s, distance w=12m in the parts place plane of keeping out the wind between relative body of wall, the height h=2.4m of hen house inner wall.The exhaust blower of 8 48 inches is installed in hen house, and the exhaust air rate of every exhaust blower is for being 10.8m
3/ s.Above-mentioned parameter substitution formula (2) is calculated:
formula (2)
L＝[(8×10.8)÷(2.5×12)]×2-2.4＝3.36m
Therefore,, for the hen house of above-mentioned scale, after mounting block wind part, its lower edge should be 3.36 meters from the appropriate distance of hen house bottom surface.
Example 2: as depicted in figs. 1 and 2, the cross sectional shape of B hen house is comprised of rectangle and triangle, suppose that we wish by mounting block wind part 2, make the mean wind speed in hen house reach 2.5m/s, at the planar distance w=16m between body of wall relatively of 2 of parts that keeps out the wind, the height h=2.4m of hen house inner wall.The exhaust blower of 11 48 inches is installed in hen house, and the exhaust air rate of every exhaust blower is 10.8m
3/ s.Above-mentioned parameter substitution formula (2) is calculated:
formula (2)
L＝[(11×10.8)÷(2.5×16)]×2-2.4＝3.54m
Therefore,, for the hen house of above-mentioned scale, after mounting block wind part, its lower edge should be 3.54 meters from the appropriate distance of hen house bottom surface.
Example 3: as depicted in figs. 1 and 2, the cross sectional shape of C hen house is comprised of rectangle and triangle, suppose that we wish by mounting block wind part 2, make the mean wind speed in hen house reach 2.5m/s, at the planar distance w=16m between body of wall relatively of 2 of parts that keeps out the wind, the height h=2.65m of hen house inner wall.The exhaust blower of 11 48 inches is installed in hen house, and the ventilation of every exhaust blower is for being 10.8m
3/ s.Above-mentioned parameter substitution formula (2) is calculated:
(formula 2)
L＝[(11×10.8)÷(2.5×16)]×2-2.65＝3.29m
Therefore,, for the hen house of above-mentioned scale, after mounting block wind part, its lower edge should be 3.29 meters from the appropriate distance of hen house bottom surface.
Further, practical experience surface, the parts 2 that keep out the wind are too small from the distance of hen house bottom surface, in causing above-mentioned hen house, the inhomogeneous problem of wind speed, also make the static pressure in hen house increase, and the increase of static pressure will cause the generation of following problem:
1. the static pressure of hen house is higher, and negative pressure is larger, and air is easier to be entered from leaking out of hen house, by wet curtain, is not lowered the temperature and is directly entered in hen house, thereby causing the cooling-down effect of longitudinal ventilation poor.
2. the increase of static pressure has increased the exhaust resistance of exhaust blower, directly cause the operating efficiency of exhaust blower to reduce, can make operating efficiency reduction by 30% even more, and the reduction of exhaust blower efficiency, hen house inner air flow and exchange have been reduced, thereby reduced the cooling air volume that enters hen house by wet curtain, the effect that makes hen house pass through Wet-curtain temperature reducing reduces.In addition, the increase of exhaust resistance, has increased the carrying of exhaust blower fan blade, will cause like this exhaust blower shortening in service life.
In sum, this programme by formula 2 clear and definite the distance of keeping out the wind between parts 2 and hen house bottom surface, not only solved the inhomogeneous problem of wind speed in hen house, and make static pressure in hen house be positioned at rational scope, thereby when guaranteeing " wet curtain-negative pressure " cooling-down effect, extended the service life of exhaust blower.
Practical experience by for many years shows, no matter the scale of hen house is much, during mounting block wind part 2, the parts 2 that keep out the wind are to the distance between hen house bottom surface more preferably greater than equaling 2.7m within it.In addition, the parts 2 that keep out the wind can only help out to increasing mean wind speed in hen house, and should be as the Main Means that improves wind speed.Generally, the mean wind speed that mounting block wind part 2 improves should be controlled in 0.5m/s scope, and any expectation therefrom obtains higher wind speed, may cause the result of running counter to desire.
Further, according to the difference of the actual scale of hen house, the quantity of the parts 2 that keep out the wind of installing also changes thereupon, and adjacent two intervals of keeping out the wind between parts exert an influence to the gentle stream of the wind speed in hen house, interval is excessive cannot realize the effect that increases wind speed, too small time static pressure increase, therefore, guarantee that adjacent two rational intervals of keeping out the wind between parts are particularly important.
Next the setting principle of windshied part part is described by an object lesson in conjunction with Fig. 3, hen house in this programme is steel building, along wetting curtain 11 to the first direction of exhaust blower 13, adopt steelframe as bearing support successively equally spaced being erected between relative two bodies of wall, the top of hen house is divided into a plurality of parts.If hen house is that ι is while being 120m along the distance between two relative bodies of wall on first direction, by being spaced apart 6m or 4.5m between adjacent two steelframes in situation, and every two steelframes, the parts 2 that keep out the wind are set, adjacent two keep out the wind and are spaced apart 9m or 12m between parts.
It should be noted that, this programme, by set up the mode of bearing support at hen house top, not only, by bearing the top load of described hen house, has improved the bearing capacity at hen house top, and the dismounting of the parts of being convenient to keep out the wind.Certainly, meeting on the basis of hen house top bearing capacity requirement, the interval in this programme between the quantity of bearing support, material and adjacent steel bearing support can be other numerical value.In addition, through practical experience sum up and repeatedly constructed experiment show, when interval D≤ι/10 of adjacent two parts that keep out the wind, can realize the effect of the interior mean wind speed of increase hen house, wherein, ι represents the two relative bodies of wall distance in a first direction of hen house.
In addition, it should be noted that, the parts that keep out the wind in this programme can be for deep bead, keep out the wind and hold court from behind a screen, or can utilize the furred ceiling in hen house to realize the effect that increases wind speed.
In sum, during longitudinal ventilation hen house mounting block wind part for improving wind speed, reducing the effect that hen house temperature has positive meaning, but we also must clearly realize that, if use mistakenly the parts that keep out the wind can cause adverse consequences equally.So not high and wind speed enough hen house again, there is no need mounting block wind part for those hen house height; And hen house height is higher, really having must be when mounting block wind part, along the distance to hen house bottom surface in the reasonable scope, unaffected to guarantee uniformity and the ventilation of wind speed in hen house under the parts that must guarantee to keep out the wind.
The foregoing is only the preferred embodiment of the present invention, do not form limiting the scope of the present invention.Any any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present invention.
