Abstract

(57) [Summary] [Purpose] A duct is installed in the rising air passage structure of the horizontal bulkhead facing the cooler room so that the cool air flows directly to the lower cargo hold and the upper cargo hold, and the cool air volume is controlled. It aims to provide a product with good freshness by allowing it to flow evenly to make the frozen temperature of the frozen cargo uniform. [Configuration] Cold air flowing under the lower grating deck 12 is branched into cool air for the lower stage and cool air for the upper stage at the rising portion of the horizontal partition wall 2 facing the cooler room 8.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rising air passage of a horizontal bulkhead facing a cooler room in a cargo hold of a refrigerating ship.

[0002]

[Prior art]

 Conventionally, in this type of device, as shown in FIGS. 3 and 4, the cargo hold 30 is surrounded by front and rear horizontal bulkheads 31, outer plates 32 and upper and lower decks 33 and 34 for each section, and a heat insulating material is provided. I was covered with 35.

Further, the frozen barge 30 was divided into upper and lower cargo spaces by a grating deck 36, and a cargo 37 was loaded on each deck.

The cooler room 38 is partitioned by a partition wall 39 in front of or behind the cargo hold 30 and a refrigerator 40 is arranged to circulate cold air.

Return ports 41 are provided at several places on the upper part of the upper partition wall 39, and on the lower part of the lower partition wall 39, the wind of the grating deck 42 of the bottom joist structure of the freezing barn 30 is provided. Dozens of air outlets 43 flowing into the road were arranged side by side in the lateral direction of the hull.

Cooling air was sequentially blown out from the small holes 47 of the grating deck 42 to cool the lower coin 37.

The rising air passage structure of the horizontal partition wall 31 facing the cooler room 38 has a wooden plywood 44 stretched over the heat insulating material 35 and a spar ring 45 (wooden timber) provided in the vertical direction. The cargo 37 in the lower stage is closely attached to the sparring 45 and loaded to form a duct 46, which serves as an air passage. Further, the cargo 37 in the upper stage was brought into close contact with the sparring 45 and loaded to form a temporary duct 46 and an air passage, but cold air leaked in the middle and did not reach the uppermost stage.

The cold air that has cooled the lower cargo 37 further circulates through the small holes (not shown) in the grating deck 36 to cool the upper cargo 37.

[0009]

[Problems to be solved by the device]

 As mentioned in the prior art, we try to load cargo into the cargo hold and to keep all cargo at a uniform temperature, but the circulation of cold air is not uniform, and cargo far from the cooler room is cold and close to it. Had a problem that there was spotting and a phenomenon that it cooled well (short circulation) appeared.

The present invention has been made in view of the above problems of the conventional technique, and an object thereof is to provide a lower air passage structure of a horizontal partition wall facing a cooler room. We will arrange ducts so that the cold air will flow directly to the cargo holds of the above and the cargo holds of the upper stage, and to make the flow rate of the cold air even, to make the frozen temperature of the frozen cargo uniform, and to provide the frozen cargo with good freshness. It is what

[0011]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention divides the cool air flowing under the lower deck of the lower deck into the cool air for the lower stage and the cool air for the upper stage at the rising part of the horizontal partition facing the cooler room, Make the cooling temperature of the entire cargo uniform.

[0012]

[Action]

 This device circulates the cool air from the bottom to the top, and installs ducts in the distance to make the cool air even near and far from the cooler room, reducing friction loss of the cool air and making the cool air uniform over the cargo hold. And the temperature of the entire cargo becomes uniform.

【Example】

 An embodiment will be described with reference to the drawings. As shown in FIG. 1 and FIG. 2, a cooling / freezing barn 1 is surrounded by front and rear horizontal partition walls 2, an outer plate 10, and upper and lower decks 3 and 4 for each section. It is covered with heat insulating material 5.

The cargo barge 1 is divided into upper and lower cargo barges 1 by a grating deck 6 and cargos 7 are loaded on the respective decks.

The cooler room 8 is partitioned by a partition wall 9 in front of or behind the cargo hold 1 and a refrigerator 20 is arranged.

At the upper part of the upper partition wall 9, return ports 11 are provided at several places, and at the lower part of the lower partition wall 9, in the air passage of the grating deck 12 of the lower joist structure of the cargo hold 1. Several tens of blown air inlets 13 are arranged side by side in the lateral direction of the hull.

Cooling air is sequentially blown out from the small holes 14 of the grating deck 12 to cool the lower goods 7.

The rising air passage structure of the horizontal partition wall 2 facing the cooler room 8 has a wooden plywood 15 stretched over the heat insulating material 5,

In the lower stage, a duct 16 is provided on the wooden plywood 15 with an appropriate width from the ship side to the ship side, and a spar ring 17 (wooden lumber) is provided in the longitudinal direction so that the cargo 7 in the lower stage is closely attached to the spar ring 17. By loading and loading, a temporary duct 18 is formed and serves as an air passage, and the lower cargo hold 1 is circulated.

The upper stage is connected to the lower duct 16 and is provided with a spar ring 19 (wooden lumber) in the longitudinal direction. The upper stage cargo 7 is brought into close contact with the spar ring 19 to be loaded, thereby providing a temporary duct ( (No drawing number) has been created, and it is an air passage, and it is designed to circulate the cargo hold 1 on the upper stage and return to the return port 11.

The cold air that has cooled the lower cargo 7 further circulates through the small holes (not shown) of the grating deck 6 to cool the upper cargo 7, and returns to the return port 11.

[0022]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. In this device, the cold air flowing under the lower deck of the lower tier is divided into the cold air for the lower tier and the cold air for the upper tier at the rising part of the horizontal bulkhead facing the cooler room to prevent short circulation and to prevent short circulation. It has the effect that the cold air volume can be made to flow evenly to the cargo, the freezing temperature of the cargo can be made uniform, and the freshness of the frozen cargo can be maintained.
