Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facility for raising large numbers of experimental animals such as mice and rats.

(Prior art) As shown in Fig. 6, a conventional breeding facility for this species has a rack 2 installed in a room with an air supply port 13 in the ceiling and an exhaust port 14 in the lower part of the side wall. Breeding containers 5 are lined up.

Fresh air that has passed through the air conditioning system 3 is supplied from the air supply port 13, and indoor air is sucked and exhausted from the exhaust port 14 to forcefully ventilate the room.

(Problems with the prior art) When we examine the flow of indoor air, we find that most of the fresh air supplied indoors comes from the space formed between the outer periphery of the rack and the ceiling, floor, and walls of the room, and the space inside the container. Only a small amount of fresh air passes through the top, flows from the rear of the rack to the exhaust port 14, and flows into the liver breeding container.

For this reason, a ventilation volume that replaces the indoor air approximately 15 times per hour is required, which increases the size of ventilation equipment and increases initial and running costs.

(Means for Solving the Problems) The present invention is devised so that fresh air always passes through the rack, and its structure is such that fresh air is formed between the outer periphery of the rack 2 and the ceiling, floor, and wall surfaces of the room. The air supply side space 11 is created by partitioning the space and narrowing the rack.
and an exhaust side space 12.

An air supply port 13 is provided in the air supply side space, and an exhaust port 14 is provided in the exhaust side space, and the front opening facing the air supply side space of each rack stage is closed with a curtain 7 that can be opened and closed over multiple rack stages. , a ventilation hole 71 is opened in the curtain 7.

(Function) The outer periphery of the rack and the ceiling, floor, and wall of the breeding room are partitioned, and fresh air supplied to the air supply side space is vented to the ventilation hole 7 of the curtain 7 that closes the rack opening.
1 into the rack 2.

(Effects) The fresh air flowing into the rack 2 through the ventilation hole 71 of the curtain 7 effectively ventilates the inside of the container, and can prevent air from staying inside the container.

Fresh air is not wasted through the outside of the rack and is ensured that all of the fresh air passes through each rack stage, resulting in an air conditioning system with a smaller capacity than before. Initial costs and running costs can be reduced, and containers 5 in the rack 2 can be taken out by opening the curtain 7, and the rack itself can also be taken out freely if the rack is equipped with wheels. Further, the amount of ventilation to each stage of the rack 2, that is, the rearing container 5, can be adjusted by the size and position of the ventilation hole 71 of the curtain 7.

Furthermore, when the curtain 7 and the rack 2 are narrowed, the air supply side has a higher pressure than the exhaust side, so air does not flow back from the rack 2 to the air supply side.
It can prevent infection between animals.

(Example) The breeding room 1 has a passageway in the longitudinal center of the room, and racks 2, 2 are placed on both sides of the passageway.

A partition plate 4 is used to partition the outer periphery of the rack 2 and the ceiling, floor, and wall surfaces of the room, and the rack 2, 2
It is divided into an air supply side space 11 in between and an exhaust side space 12, 12 behind the racks 2, 2, and entrances and exits 16, 17 are provided at appropriate positions in the rearing room 1 and the partition plate 4.

A plurality of air supply ports 13 are provided on the ceiling of the air supply side space 11, and an air conditioning system 3 consisting of an air conditioner 31, a fan 32, a filter 33, and a heater 34 is installed in the air supply ports. The system creates air conditions suitable for breeding animals, and this fresh air is sent into the air supply side space 11 from the air supply port 13.

A plurality of exhaust ports 14 are provided in the ceiling of each exhaust side space 12, 12, and a fan 15 is connected to the exhaust ports 14.

Each stage of the rack 2 has its entire surface open on the side facing the air supply side space 11, and has a back plate 22 on the side facing the exhaust side space 12 with a space between it and the upper shelf board 21.
has been established.

On the back plate 22 is a space adjustment plate 2 that can be slid vertically and positioned using clamp screws 24.
3 or a constant air volume valve (not shown) is installed.

On each shelf board 21 of the rack 2, transparent breeding containers 5 made of synthetic resin with open tops are placed in parallel with the adjacent containers, and the height of the container is the same as the height of the back plate 22. A circulation space is formed between the upper shelf board 21 and the upper shelf board 21.

A curtain rail 72 is arranged at the front edge of the ceiling plate 20 at the top of the rack 2 over the entire length of the rack 2, and a transparent curtain made of synthetic resin is hung close to the rack.

A plurality of curtains 7 are hung so as to completely cover the opening surface of the rack 2.

A large number of ventilation holes 71 are regularly provided in each curtain 7, corresponding to the space between each shelf board 21 of the rack 2 and the container 5 below the shelf board.

As shown in Fig. 4, on the bottom surface of the shelf board 21 of the rack 2,
A baffle plate 6 is attached close to the curtain 7 so as to be swingable back and forth.

However, the outer periphery of the rack 2 and the interior ceiling, floor and walls are separated by a partition plate 4.
Fresh air supplied to the air supply side space 11 flows out from the ventilation hole 71 of the curtain 7 through the rack 2 to the exhaust side space 12.

Therefore, air stagnation within the rack 2 is prevented, and by providing the baffle plate 6 on the bottom surface of each shelf board 21 as in the embodiment, fresh air passing through the rack 2 is prevented from stagnating on the baffle plate 6. Since the air is forcibly guided into the container 5, air stagnation within the container can be prevented even if the container is a plastic container without ventilation holes in the peripheral wall. Furthermore, when the curtain 7 and the rack 2 are narrowed, the pressure on the air supply side is higher than that on the exhaust side.
Air does not flow back from the rack 2 to the air supply side, and infection between animals can be prevented.

Furthermore, the upper end of the baffle plate 6 is pivoted so that it can swing back and forth, so when the force of the airflow flowing in from the ventilation hole 71 of the curtain 7 is strong, the baffle plate 6 is pushed backward and tilted, causing the container to collapse. By adjusting the amount of air flowing into the lower part, there will be no inconvenience caused by strong winds hitting the animals inside the container.

Since the curtain 7 is made of transparent resin, light enters the rack 2 even when the curtain is closed, so that the animal's condition can be clearly seen without harming the animal's health.

In addition, by providing a space adjustment plate 23 on the back of the rack 2 to equalize the amount of air flowing out from the ventilation holes 71 of the curtain 7, the flow of air passing through the rack becomes smooth, and the air flow near the back of the rack 2 is made equal. There is no vortex flow in which the air blown into the exhaust space returns to the inside of the rack, resulting in excellent ventilation of the entire breeding room.

Further, in order to take in and take out some containers, the curtain 7 can be opened only in the necessary part, and in order to take in and take out all the containers, it is sufficient to open the curtain 7 fully, and the presence of the curtain does not interfere with taking out and taking out the containers.

In addition, when carrying out the present invention, as shown in FIG.
A net container 5 is housed in each tier of the rack 2, and a curtain 7 has a large number of ventilation holes 7 corresponding to the front positions of the containers.
You can also open 1.

Furthermore, the partition plate 4 shown in FIG. 2 can be omitted and the curtain 7 can be suspended from the ceiling.

Furthermore, it is also possible to adjust the amount of ventilation into the container 5 by adjusting the size and position of the ventilation holes 71 of the curtain 7.

The present invention is not limited to the above configuration,
Of course, various modifications are possible within the scope of the claims.
