Description

[Detailed Description of the Invention] This invention relates to a ventilation system for containers, and is particularly suitable for application to a ventilation system for maritime containers.

In modern containers, opportunities to transport perishables such as grains and fruits have increased, and cargo spoilage can occur due to excess moisture inside the container due to the respiration of these perishables, and condensation due to temperature differences inside and outside the container. This has led to the need to increase the ventilation capacity of ventilation systems.

However, if ventilation holes are easily installed on the limited outer surface of the container, it will not only drain rainwater like a sea container. If the container is placed in an environment where there is splash from waves, moisture can easily enter the container and damage the cargo.

Therefore, as shown in FIG. 1A, a container ventilation system 1 is attached to a wall panel 3 near the top rail 2, and a ventilation hole 4 leading to the outside of this ventilation system 1 is
As shown in FIG. 1B, a ventilation hole 10 is provided only in the lower wall 5 of the ventilation device 1, and a ventilation hole 10 is provided in the upper part of the container side of the ventilation device 1 in correspondence with the ventilation hole 6 provided in the wall panel 3 of the container. There is one in which a drain plate 9 with communication holes 8 is arranged in multiple layers in the passage 7 to prevent moisture from entering the container. However, in such a ventilation system 1, if a large amount of upward sea spray is applied to the container and this wave spray continuously enters the ventilation system 1 through the ventilation hole 4, the ventilation hole 4, which also serves as a drainage hole, will be damaged. This is disadvantageous in that drainage is obstructed and water easily enters the inside of the container.

In the container ventilation system according to this invention, a large number of ventilation holes are provided on the side walls of the outside of the container to ensure sufficient ventilation, and water that has entered the ventilation system is reliably separated using a specially constructed drain plate. It is designed to allow drainage and prevent water from entering the container.

An example in which this invention is applied to a ventilation system for a sea container will be described below with reference to FIGS. 2 to 7.

Maritime containers (hereinafter referred to as "containers") are
As shown in Fig. 2, double door opening/closing door 12 is located at the rear.
This container has a hexahedral structure, and this container has a rectangular parallelepiped-shaped frame formed from a top rail 13, a bottom rail 14, and a pair of pillars 15 at the front and rear, respectively, arranged at the top and bottom of the container. There is. On both sides and the front of this frame,
The wall panel 16 is formed by fitting a corrugated board so that its protrusions 17 and grooves 19 extend in the vertical direction. The ventilation system 18 for the container includes a cover plate 20 attached to the concave strip 19 of the wall panel 16 on the outside of the container so as to cover the concave strip 19.

That is, this cover plate 20 mainly forms the side wall surface of the ventilation device 18, but the upper part of the cover plate 20 is designed so that the ceiling of the ventilation device 18 has a single-flow type with good water drainage, as shown in FIG. It is bent diagonally, and both upper and lower ends of the cover plate 20 are bent so as to be parallel to the portion forming the side wall surface. Then, this bent portion is attached to the wall panel 16, and both side edges of the cover plate 20 are attached to the wall panel 16 to form the ventilation device 18.

By the way, FIG. 3 shows a vertical section of the ventilation device 18, and FIGS. 4 and 5 show a cross section of the ventilation device 18. In the ventilation room 21, wall panel 1
A plurality of longitudinal drainage plates 22 whose upper ends are brought into contact with the ventilation chamber 21 and which extend downward are diagonally arranged in parallel and at equal intervals in the longitudinal direction of the ventilation chamber 21.

The adjacent longitudinal drain plates 22 are arranged such that the lower part of the upper longitudinal drain plate 22 and the upper part of the lower longitudinal drain plate 22 overlap each other in the lateral direction of the ventilation room 21. Further, the longitudinal draining plates 22 are formed in a channel cross section, so that each longitudinal draining plate 22
The distance between the pair of flange portions 22a and 22b is,
It is substantially the same regardless of the length direction of the longitudinal draining plate 22. The upper end of the web portion 22a of the longitudinal draining plate 22 is in contact with the wall panel 16 as described above.

As shown in FIG. 7, in the flange portions 22a and 22b of each longitudinal draining plate 22, the lower longitudinal draining plate 2
The flange portions 22a, 22b of the upper and lower longitudinal drain plates 22 are cut out, and the flange portions 22a, 22b of the upper longitudinal drain plate 22 are fitted into the cutout portions 22d.
form a partition wall 26 that extends vertically.

Thus, the first air passage 27 is formed between the overlapping portions of the adjacent longitudinal draining plates 22, and the lid plate 20 is formed between each longitudinal draining plate 22 and the cover plate 20.
A steam/water separation chamber 24 is formed in the center of the ventilation chamber 21, and a pair of left and right second ventilation passages 25 are provided on both sides of the ventilation chamber 21.
is formed. A communication section 28 is formed above each longitudinal draining plate 22 by the longitudinal draining plate 22 directly above and the wall panel 16, and the first air passage 2
7 communicate with the pair of second air passages 25 through the communication portions 28, respectively.

Further, a partition plate 30 is attached near the lower end of the lowest longitudinal drain plate 22, and this partition plate 30 connects the lower part of the communication section 28 formed by the longitudinal drain plate 22 and the wall panel 16, and the second ventilation A drainage chamber 31 is provided in the lower part of the ventilation chamber 21 which communicates with the air-water separation chamber 24 by blocking the lower portion of the passage 25 .

Next, the lid plate 2 which becomes one side wall of the steam/water separation chamber 24
A large number of first ventilation holes 33 and drainage holes 35 communicating with the outside are provided in the portion of the cover plate 20 that serves as the lower wall 32 of the ventilation chamber 21, and the wall that forms the communication portion 28. A large number of second ventilation holes 34 on the inside side of the ventilation device 18 are provided in the panel 16. Note that the second ventilation hole 34 provided in the wall panel 16 may be provided in the side wall of the grooved portion 19 in the wall panel 16, as shown in FIG.

Thus, in the container ventilation system 18 described above,
As shown in FIG. 3 or FIG. 7, for example, ventilation accompanied by moisture flowing in from the first ventilation hole 33 leading to the outside in the direction of arrow A in the figure collides with the front drainage plate 22 and releases kinetic energy. The water that is consumed and has a large mass moves down the steam/water separation chamber 24 while being transmitted to the longitudinal draining plate 22, and mainly flows into the lower wall 3.
The water is discharged to the outside of the ventilation system 18 through the drain hole 35 of No. 2. Then, the ventilation that has lost moisture rises in the first ventilation path 27 as shown by arrow B in the figure and reaches the communication section 28, and a part of it reaches the communication section 28.
The remaining air flows into the container from the second ventilation hole 34 opening at the bottom, and the remainder flows into the container from the second ventilation hole 34 at the lower side via the second ventilation path 25.

In this case, the first ventilation hole 33 leading to the outside is
Since it is provided on the side wall of the ventilation device 18, ventilation with a large horizontal vector component easily flows into the ventilation room, but since the angle (α) between the drain plate 22 and the wall panel 16 is extremely small, It is difficult for the moisture after colliding with the draining plate 22 to rise up the first air passage 27 and reach the communication portion 28 . In addition, ventilation with a large upward vector component is difficult to pass through the first ventilation hole 33 leading to the outside, and even if it passes through and flows into the steam/water separation chamber 24, it consumes kinetic energy. , there is no risk of the air flowing up the first ventilation path 27 and reaching the communication portion 28 as in the case described above.

By the way, for example, upward wave spray easily flows in from the drain hole 35 provided in the lower wall 32 of the ventilation room 21, but because of the partition plate 30, this wave spray can flow directly or into the second ventilation path. 25 into the communication portion 28 and flow into the container through the second ventilation hole 34. The inflowing wave spray passes through the drainage chamber 31 and passes through the air-water separation chamber 2.
4, even if a large amount of water such as sea spray continuously flows in, the first ventilation hole 33 is provided in the side wall of the steam/water separation chamber 24. It will be easily discharged out of the ventilation device 18 through the pores 33.

The present invention is not limited to the marine container ventilation system of the above-described embodiment, but can be applied to various types of container ventilation systems.

Further, in the ventilation system of the embodiment, a corrugated board is used for the wall panel 16, but a corrugated board other than a corrugated board can be used. Furthermore, ventilation equipment 1
8 is a convex strip 17 shown in FIG. 2 of the corrugated board.
It is also possible to install it inside the container using the . In this case, the positions of the wall panel 16 and the cover plate 20 shown on the left and right sides in FIG. 3 are interchanged.

Further, it is sufficient that there are at least two or more of the plurality of draining plates 22, and these draining plates 22 are arranged parallel to each other at equal intervals, but such a limitation is not particularly required. In addition, the drain plate 22
A gap may be created between the upper end of the wall panel 16 and the wall panel 16 without contacting each other.

Furthermore, the cross section of the draining plate 22 is made into a channel shape, and the flange portions 22a, 22b of each draining plate 22 are made into a channel shape.
are connected to form a partition wall 26 that extends over almost the entire length of the cover plate 20, but the drain plate is not provided with such flange portions 22a and 22b, and a pair of partition plates are provided on both side edges of the drain plate 22. The partition wall 26 may also be formed by attaching a. In addition, in the embodiment, the drain plate 22 of the channel cross section is used, and the communication part 2
8 is formed in a triangular shape as shown in FIG. The partition wall 26 can be provided with a moisture removal function for ventilation flowing out into the second ventilation path 25.

Furthermore, as shown in FIG.
If a diaphragm 36 is provided in the communication section 28 near the outlet, most of the ventilation coming out of the first ventilation path 27 will flow out from the communication section 28 to the second ventilation path 25, and then the ventilation will flow through the communication section 28 at the bottom. The second ventilation hole 34 provided in 28
The ventilation path is not only tortuous but also extremely long.
Ventilation will be drained sufficiently.

A ventilation system for a container according to this invention includes a corrugated plate that constitutes a wall panel of the container and has a groove extending in the vertical direction, and a corrugated plate that is attached to the container so as to cover the groove. a lid plate that forms a vertical ventilation chamber between the side wall surface forming the grooved portion, a first ventilation hole formed in either one of the corrugated plate and the lid plate, and the other of these. A second ventilation hole formed in the vertical ventilation chamber is arranged so as to extend substantially vertically into the vertically elongated ventilation chamber, and the positions of the ventilation holes are sequentially shifted in the height direction, and the wall surface thereof is connected to the first ventilation hole. A plurality of longitudinal draining plates facing each other are provided, and the lower part of the upper longitudinal draining plate and the upper part of the longitudinal draining plate one level lower than the upper longitudinal draining plate are provided between these. A ventilation passage extending substantially vertically is formed, and the lower wall surface is connected to the first
are stacked so as to face the ventilation holes, and ventilation introduced into the ventilation room from the outside through the first ventilation hole is guided to the longitudinal drainage plate and then through the second ventilation hole. It was configured to be installed inside the container.

Therefore, according to this invention, the ventilation device utilizes the grooves in the wall panel and is embedded in the grooves, so the thickness of the container wall is increased due to the ventilation device, or the wall surface is There are no protruding parts that cause any inconvenience to cargo handling operations, and the structure is simple and can be manufactured at low cost.

Furthermore, since the longitudinal drainage plate is installed in a vertically elongated ventilation room, it can be made sufficiently long, and as a result, the first ventilation path is also sufficiently long, so that moisture can There is no fear that the air will rise up the ventilation path and flow into the container. Moreover, the large number of ventilation holes made it possible to significantly increase the amount of ventilation.

Therefore, even if the cargo is perishable, the respiration of the cargo will not be hindered, and the overhumidity inside the container due to this respiration can be eliminated, and the container will be more stable due to temperature changes. It also prevents condensation inside the container, which prevents the cargo from spoiling.
