JPH03191242A - Ventilating method for cattle shed and its apparatus - Google Patents

Abstract

PURPOSE:To considerably improve the circumstances of an existing facility with a rather small amount of investment required only for providing at least two air fans, by a method wherein the air inside a cattle shed is gathered by a second air fan to send it to a first air fan, and discharged outside by the first air fan. CONSTITUTION:Two or more air fans, e.g., first, second and third fans 12, 13 and 14, are located at the first, second and third positions in order and arranged one behind another in a line at distances which allow the air flow of a fan to reach the other fan on the down stream. And, when the fans 12-14 are operated together, the air in a cattle shed 10 flows in the direction shown by arrows F1, F2, and F3, that is, the air is sent in turn from fan 14 to the fan 13, from the fan 13 to the fan 12 and finally discharged outside by the fan 12. Thereby, the incoming air flow from the outside is forcibly developed and a circulating air flow is produced between the inside of the cattle shed and the outside. Therefore, the air in the cattle shed is kept clean.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a ventilation method and apparatus for a livestock breeding house for raising livestock such as pigs and chickens.

(Conventional collisions and their problems) This type of livestock housing is full of strong odors, dust and germs caused by the movement of the animals, and is not only an obstruction to the rearing, but also a [r] Hygiene has become a major problem in the working environment of workers.

Conventionally, one way to improve this unsanitary environment has been to make the enclosure a closed structure and install an air conditioner to it, but this structure and equipment Because this method requires a large amount of capital investment, it is a difficult method for small and medium-sized livestock breeders to adopt.

For this reason, small and medium-sized i5 breeders keep their breeding houses open and well-ventilated. The current situation is to create a calm structure and hope for ventilation by natural winds.

Unissued 1!1 aims to improve this current situation.

(Means for Solving the Problem) The first invention relates to a ventilation method for a livestock breeding house, which is used for breeding livestock such as pigs and chickens.

-1- In the breeding house, a first ventilation fan is arranged at a first position where the airflow flowing towards the window leading to the outside world of the breeding house flows, and a first ventilation fan is placed in the rear direction of this first ventilation fan. A second blower fan is installed at a second position where the airflow flows, and the first blower fan and the second blower fan are operated simultaneously to remove the air in the breeding house that remains near the second blower fan. , collected in the second blower fan and sent to the first blower fan,
The feature is that the air inside the enclosure is forced to flow out into the outside world by being discharged to the outside world using the first blower fan.

The second invention relates to a ventilation system for a livestock breeding shed.

In a device that uses a blower fan to ventilate a breeding house for raising livestock such as pigs and chickens.

The device described in J.2 consists of at least a plurality of blower fans,
The first blower fan is placed at the first position where the blown air flows towards the window leading to the outside world of the breeding house, and the wS2 blower fan is placed in the rear direction of the first blower fan where the blown air flows. A plurality of airflow fans are placed at a second position t where the airflow flows, and a third blower fan is located behind the second airflow fan at a third position where the blown airflow flows. The blower fans are arranged in sequence in the rear direction at intervals where the blown air flows, and the air inside the breeding house is sequentially sent out to the blower fans located in the front direction, and the air is flowed out to the outside world by the first blower fan. The configuration is such that the

(Example) The present invention will be described below based on drawings showing an example of implementation.

Figure 1 is a vertical sectional view of the breeding house 10, and Figure 2 is a vertical cross-sectional view of the breeding house 10.
It is a horizontal cross-sectional view of O.

The breeding house 10 has a plurality of windows of appropriate size,
It is a structure that is open to the outside world.

Any window 1 among these multiple windows 11.11A and IIB
Let 1A be the window leading to the outside world.

First, the first blower fan 12 is placed at an appropriate spatial position within the pen IO, facing the window 11A communicating with the outside world. The first blower fan 12 must be in a position where the airflow blown therefrom flows and further flows out from the window 11A to the outside world.Hereinafter, this position will be referred to as a first position.

In the embodiment, the first blower fan 12 is suspended from above the room so as to occupy this first position, but the invention is not limited to this, and it may be supported from the floor or supported from the nearest pillar (not shown). It may be constructed in

In this way, with respect to the first blower fan 12 placed at the first position, the second blower fan 13 is further placed behind the first blower fan 12 .

This second blower fan 13 also. This must be the position where the blown air flows, reaches the first blower fan 12, and is sucked in. Hereinafter, this position will be referred to as the second position.

Of course, the amount of airflow sucked into the first blower fan 12 is
It is not necessary that the entire airflow is from the second blower fan, as long as an appropriate amount of airflow can be generated between the room and the outside world, as will be described later.

Further, in this embodiment, a third blower fan 14 is arranged behind the second blower fan 13 arranged at the second position in the same manner as the second blower fan 13 for the first blower fan 12. ing.

That is, this third blower fan 14 as well. It must be in a position where the blown air flows, reaches the second blower fan 13, and is sucked in.

This position is called the third position.

In this way, if the second and third positions are respectively
At least a plurality of blower fans 12 to 12, such as a blower fan 12, a second blower fan 13, and a third blower fan 14,
14 are lined up in sequence behind each other at intervals where the blown air flows, and are operated simultaneously, the air inside the breeding house 10 flows in the direction of the arrows F1→F2→F3, that is, in the direction of each blower fan. The air is sequentially sent out to the blower fan 13.12 located in the front direction of the first air blower 14.13.
The air is blown out to the outside by the blower fan 12.

As a result, the air inside the breeding house 10 flows out to the outside world, and on the other hand, it is possible to forcibly generate an airflow flowing in from the outside world, and it is possible to generate a circulating airflow between the inside of the breeding house 10 and the outside world.

(Effects of IJI) 1. According to the second aspect of the invention, circulating airflow can be forcibly generated between the inside of the breeding house of the existing equipment and the outside world simply by arranging a plurality of blowing fans equipped with appropriate blowing acid.

Therefore, it is possible to release dust and germs caused by strong odors generated in the breeding house and the movement of the animals being kept into the outside world, making the interior of the breeding house cleaner than before. .

Therefore, not only the animals being kept, but also the working environment of the breeding staff is t! It is good for people and is hygienic.

In particular, one advantage of the present invention is that the environment of existing equipment can be greatly improved with a relatively small investment of just preparing at least two blower fans.
