JPH02109928A - Ventilation of poultry-farming house and dropping drier - Google Patents

Abstract

PURPOSE:To effect the ventilation and drying of fowl droppings simultaneously to remove bad odor by allowing the air in the poultry-farming house always to flow from the upper part to the lower part and drying the fowl dropping simultaneously with the air circulating in the house. CONSTITUTION:The poultry-farming house is provided with the draft air duct 1 in the attic story and the slits 2 are opened on the bottom of the duct 1 to blow the air from the duct 1 into the house. At the same time, baffle plates 3 are set near the slits 2 on the house side to distribute the air coming in from the slits. In the meantime, opposing cages 5 are set on the floor in the house so that the space uppermost a gradually expands downward, for example, b and c, and dripping receivers 6 are set outside the bottoms of each cage 5 so that they have a small inclination toward the center line of each slit. Further, the slits 7 for exhaustion are opened on the parts of the floor corresponding to the extension of the center lines of the slits, respectively, and the height 8 up to the floor is set suitably.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a method for ventilating the inside of a poultry house,
This invention relates to a device that simultaneously dries chicken manure and removes odors.

(Prior art) Conventional ventilation systems for poultry houses include an air duct installed in the attic, a blower that forcibly sends outside air into the duct, and a slit provided at the bottom of the air duct into the house. The poultry manure was brought into the house and exhausted from the lower part of the side wall of the house, and there was no equipment for drying chicken manure.

(Problem to be solved by the invention) However, in the above-mentioned device, the air is forced into the air supply duct by the blower and the air that flows in through the slit is circulated inside the house for ventilation. However, when the forced air circulates inside the house, wind is naturally generated, and this wind causes the blades,
Part of the feed or chicken manure, etc., circulated at the same time and filled the house, and the environment inside the house could not be said to be good.

Moreover, since there is no equipment to dry chicken manure,
The house was always filled with a foul odor, making it difficult for even experienced workers to work efficiently inside the house.

In view of the above points, it is an object of the present invention to provide a device that can remove bad odors in the house by suppressing the circulation of unnecessary blades for ventilation and drying chicken manure. be.

(Means for Solving Problems) In order to achieve the above object, the present invention provides an air duct etc. in the attic, and provides a slit in the bottom of the air duct for sending air from the air duct into the house. In a ventilation system for a poultry house that ventilates the house by forcibly blowing air from the top to the bottom of the house, a barrier plate is installed near the inside of the house in the slit to disperse the forced air. , Several stages of opposing cages are installed on the floor with the opposing gap gradually widening from the top to the bottom, and a slight downward slope is placed outward at the bottom of each cage in the direction of the center line of the gap. A feces receiving plate is provided, an exhaust slit with an appropriate width is provided in the body part on the central extension of the gap, and an underfloor is provided with a height sufficient to accumulate feces.

(Function) With the above configuration, the air that is forced to flow in through the slit is dispersed above the cage by the obstruction plate, spreads throughout the interior of the house, and is then exhausted under the floor through the exhaust slit in the floor. It will be done. At this time, the direction of air flow within the house is always from above to below. As a result, even if unnecessary objects such as blades flow together with the air, they will not fly upwards and will always fall downward.
Since only \ is moved, it is possible to prevent unnecessary objects such as feathers from filling the house, and the environment inside the house is significantly improved.

In addition, by providing a droppings receiving plate on the outside of the bottom of each cage, the droppings excreted by the chickens in each cage are once received by the droppings receiving plate, and then dried by the air circulating inside the house on the droppings receiving plate. This will suppress the generation of odors due to the appropriate dry conditions, and furthermore, the odor-laden air that has passed through the excrement will be discharged outside the house through the exhaust slit, so it will be possible to eliminate the above-mentioned unnecessary materials. Similarly, the house will not be filled with water. Moreover, by periodically dropping the dried feces on the feces receiving plate to the underfloor through the exhaust slit, it becomes easier to dry the feces on the feces receiving plate, and the feces from inside the house to the underfloor are always allowed to flow through the exhaust slit. Since the air is exhausted at a constant pressure, odors do not enter the house from under the floor, making the house very comfortable for both the chickens and the workers.

(Example) Embodiments of the present invention will be described below based on the drawings.

As shown in the drawings, the present invention provides an obstruction plate (3) near the inside of the house in the slit (2) provided at the bottom of the air duct (1).
The cages (5) facing each other are installed on the floor (4) by gradually widening the gaps (b) and (c) downward from the top gap (a). ) is provided with a excrement receiving plate (6) on the outside of the lower part of each floor, and an exhaust slit (
7), and the underfloor (8) is set at an appropriate height.

Therefore, immediately after the air forced to flow in from the air supply duct (1) flows vertically downward into the house through the slit (2),
Since the air is laterally corrected by the obstruction plate 3), the air is dispersed throughout the house. The air dispersed throughout the house layer passes through each cage (5) and the feces on the feces receiving plate (6) from above to below, and then is discharged from the exhaust slit (7) to the underfloor (8). The Rukoto. The excrement excreted by the chickens raised in each cage (5) is once received on the excrement receiving plate (6) provided outside the bottom of each cage (5), and after it has dried appropriately, it falls downward. Here, as the gap between the opposing cages (5) is gradually widened from the top row downwards, the gap between the opposing feces receiving plates (6) installed outside the lower part of each cage (5) is increased. Similarly, by gradually widening the gap downward, when dropping excrement downward from the excrement receiving plate (6), it does not directly pass through the exhaust slit (7) and be discharged under the floor (8). This is intended to be dropped onto the lower feces receiving plate (6), and since this lowest feces receiving plate (6-) is closest to the exhaust slit (7), the air is removed. Since it has the highest amount of passage and can accelerate the drying of feces, it is possible to complete appropriate drying at this point, and this feces receiving plate (
The tip (9) on the opposite side of the feces receiving plate (6-) constitutes the opening end of the exhaust slit (7).
), it is easy to allow dried feces to fall to the floor.

Note that the droppings that fall under the floor (8) have a slight odor, but because pressurized air is always exhausted from the house via the exhaust slit (7), the odor will enter the house. Moreover, since the air discharged from the exhaust slit (7) has a velocity sufficient to circulate within the underfloor (8), the chicken manure that has fallen into the underfloor (8) can be further dried. It is something that can be done.

(Effects) As described above, the present invention provides sufficient ventilation inside a poultry house and prevents the house from being filled with feathers and other unnecessary materials, thereby providing the most suitable environment for poultry farming. It's something you get.

In addition, since the feces are properly dried at the same time as ventilation, the bad odor generated from the feces can be eliminated.
This provides an environment suitable for raising poultry.

Needless to say, these conditions are ideal for those working inside poultry farms.

Furthermore, by accumulating dried feces under the floor, the air discharged from the exhaust slit can dry the chicken feces under the floor again. It has the advantage of being easier to dispose of, and because chicken manure still has a slight odor even after being properly dried, it can remove the bad odor from inside the house. be.
