Definitions

• the present disclosure relates to a bulk container, and more particularly to a ventilation device for a bulk container. Background technique
• FIG. 1 is a schematic view showing the structure of a conventional bulk container.

• the inside of the ventilator is a labyrinth structure.
• the labyrinth structure generally consists of a plurality of holes, and the structure is complicated, and the vent hole has a small diameter and is easily blocked.
• the existing ventilator of the labyrinth structure cannot achieve the air pressure inside and outside the box due to the small amount of ventilation. balance.
• the present disclosure provides a ventilating device for a bulk container, through which the ventilating device of the container realizes the balance of the air pressure inside and outside the container during bulk unloading, and avoids deformation or damage of the container.
• the present disclosure also provides a bulk container including the above-described ventilation device.
• the ventilation device of the bulk container of the present disclosure comprises a ventilation pipe and a one-way cabinet; the ventilation pipe is disposed on the casing of the container, the inlet port thereof faces the outside of the container of the container, and the air outlet thereof faces the The inside of the box of the container; the one-way wide is disposed in the box of the container, and can open and close the air outlet of the air duct.
• the ventilation device further includes a detachable protective cover, the detachable protective cover is disposed in the container, and is surrounded by a part of the container to form a hollow structure, and the one-way valve is enclosed among them.
• the air duct is inclined, and the position of the air outlet is higher than the position of the inlet.
• the air duct is a hollow tube having a circular, square or short cross section.
• the one-way valve is a soft cover.
• the soft cover is fixed to the case by hinges, bolts, rivets or welding.
• the venting means is disposed on the end of the container, the end sill, the top side rail, the sill, the sill beam, the wall panel, or the roof.
• At least one of the ventilation devices is disposed on the bulk container.
• the soft cover covers the air outlet of the air duct during the normal transportation, and prevents water vapor from entering the box: the bulk cargo flows out during unloading, the air pressure inside the box is lower than the air pressure outside the box, the soft cover is naturally opened, and the box is opened.
• the air inlet of the external air ventilation duct enters the tank to achieve the balance of the air pressure inside and outside the tank, which can realize the safe transportation and safety of the container for bulk cargo. The purpose of full unloading. Illustration
• the figure is a schematic view of an existing bulk container
• Figure 2 is a schematic view of a bulk container of the present disclosure which is provided with a passage means;
• Figure 3 is a cross-sectional view of the ventilation device of the bulk container shown in Figure 2 taken along the line A-A.
• the Pf map mark is as follows: 1 ventilation pipe, 2 soft cover, 3 protective cover, 31 first "L” shaped plate, 32 “Z” shaped plate, 33 second "L” shaped plate, 41 threshold , 411 front vertical board, 412 rear vertical board, 413 bottom board, 42 door fascia board, 421 upper top board, 422 sloping board, 423 lower top board.
• the present disclosure will be described by taking a ventilation device disposed on a sill of a bulk container case as an example.
• the provision of the ventilating device on the threshold of the bulk container body is merely exemplary and is not intended to limit the disclosure.
• the ventilating device can be placed in any suitable location for the bulk container, such as end turns, end sills, roof side rails, door panels, door beams, wall panels, box roofs, and the like.
• Figure 2 is a schematic view of a bulk container with a ventilating device disposed in the present disclosure:
• Figure 3 is a cross-sectional view of the ventilating device of the bulk container of Figure 2 taken along line A A.
• a plurality of venting devices are provided on the sill of the container casing.
• the sill 41 and the sill plate 42 of the container are enclosed in a hollow columnar structure extending in the horizontal direction.
• the sill 41 is a U-shaped structure formed by bending a steel plate, and includes a front vertical plate 411 and a rear vertical plate 412, and a bottom plate 413 connecting the two vertical plates.
• the sill plate 42 is also formed by bending a steel plate, and includes an upper top plate 421, a slanting plate 422 and a lower top plate 423.
• the upper top plate 421 and the lower top plate 423 extend in a horizontal direction, and the slanting plate 422 is connected to the upper top plate 421 and the lower top plate 423.
• the upper top plate 421 is welded to the front vertical plate 411_ and the rear vertical plate 412.
• the upper top plate 421 is flush with the front vertical plate 411, and the upper top plate 421 and the inclined plate 422 are connected at the outer side of the threshold, that is, the upper top plate. 421 is wider than the bottom plate 413.
• the air duct i is a steel pipe, and the outer end thereof is welded to the front vertical plate 411 of the sill 41 to form an air inlet, and the inner end thereof is welded to the rear vertical plate 412 of the sill 41 to form an air outlet.
• the air duct 1 is inclined so that its air outlet is higher than the air inlet to prevent rainwater and the like from entering the tank.
• the soft cover 2 is a thin plate connected to the rear vertical plate 412 of the container door by a hinge, installed at the air outlet of the air duct 1, and the area of the soft cover 2 is larger than the area of the outlet of the air duct 2 to cover The air outlet of the air duct 1 is stored. During the transportation, the soft cover 2 covers the air outlet of the air duct 1 to seal the bulk container to prevent water vapor from entering the box; when the cargo is unloaded, the internal air pressure is lowered, and the atmospheric pressure opens the soft cover 2 .
• the detachable protective cover 3 includes a first "L” shaped plate 31, a “ ⁇ ” shaped plate 32 and a second “L” shaped plate 33.
• the first "L” shaped plate 31 is welded to the inclined plate 422 of the sill plate 42.
• the second "L” shaped plate 33 is welded to the rear riser 412 of the sill 41.
• the upper and lower portions of the " ⁇ " shaped plate 32 are respectively associated with the first "L” shaped plate 31 and the second The "L'' shaped plate 33 is connected by bolts and nuts.
• the second "L” shaped plate 33 and a portion of the rear vertical plate 412 of the rocker panel 42 enclose a hollow cylindrical structure extending in the sill direction.
• the hollow cylindrical structure encloses a plurality of ventilation means disposed on the sill.
• the length of the structure is narrower than the width of the interior of the bulk container so as to vacate a distance between the two ends of the hollow column structure, that is, the inner space of the hollow column structure communicates with the inner space of the container to maintain ventilation.
• the detachable protective cover 3 The goods can be prevented from directly pressing on the soft cover 2 of the air duct 1 to affect the effect.
• the bulk container of the present disclosure avoids deformation or damage of the container because the above-mentioned ventilation device can have a difference in air pressure inside and outside the bulk container, so that the air pressure inside and outside the container is balanced.
