Description

Bulk container and drafting apparatus thereof

Technical field

The utility model relates to the drafting apparatus of a kind of bulk container, particularly a kind of bulk container.

Background technology

Fig. 1 is existing bulk container structural representation.The ventilator of existing bulk container is generally riveted on both sides, two ends, top of container body etc.The inside of ventilator is labyrinth structure, and labyrinth structure is generally comprised of a plurality of holes, its complex structure, and breather port diameter is less, easily stops up.When bulk container is unloaded, because bulk goods flow velocity is fast, flow is large, cause the rapid reduction at short notice of freight container internal pressure, the ventilator of existing labyrinth structure can not make case inner and outer air pressure reach balance because its ventilation volume is too little at short notice.Even if many ventilators are installed, air can not enter in case in time, and still out of reach requirement of fanning effect causes case internal gas pressure on the low side, and the barometric pressure outside case easily causes bulk container distortion, even damages.

Utility model content

In order to address the above problem, the utility model provides a kind of drafting apparatus of bulk container, and while realizing bulk goods unloading by the drafting apparatus of this freight container, the balance of freight container inner and outer air pressure, avoids distortion or the damage of freight container.The utility model also provides a kind of bulk container that comprises above-mentioned drafting apparatus.

The drafting apparatus of bulk container of the present utility model, comprises breather pipe and check valve; Described breather pipe is arranged on the casing of described freight container, and its ventilation inlet is outside the casing of described freight container, and its air outlet is in the casing of described freight container; Described check valve is arranged in the casing of described freight container, can open and close the air outlet of described breather pipe.

Described drafting apparatus also comprises removable protection case, and described removable protection case is arranged in described freight container, is encircled into hollow structure with the part casing of described freight container, and described check valve is surrounded therein.

Described breather pipe is obliquely installed, and the position of described air outlet is higher than the position of described ventilation inlet.

Described breather pipe is that cross section is the hollow tube of circular, square or rectangle.

Described check valve is soft cover plate.

Described soft cover plate is by hinged, bolt, rivet or be fixedly welded on described casing.

Described drafting apparatus is arranged on end lintel, end sill, top beam of laterally, door-plate, door crossbeam, wallboard or the case top of described freight container.

Another object of the present utility model is to provide a kind of bulk container that comprises above-mentioned drafting apparatus.

Drafting apparatus described at least one is set on described bulk container.

According to freight container of the present utility model, in transportation, soft cover plate covers, prevents that by the air outlet of breather pipe steam etc. from entering in case at ordinary times; During unloading, bulk goods flows out, case internal gas pressure than low, the soft cover plate of the outer air pressure of case naturally open, thereby case outer air enters in case and reaches case inside and outside air pressure balance from the air intake vent of breather pipe, can realize freight container for the object of unloading with safety of transporting safely of bulk goods.

Fig. 2 arranges the schematic diagram of ventilate bulk container on lintel of the present utility model;

Fig. 3 is the A-A cutaway view of the drafting apparatus of bulk container shown in Fig. 2.

Wherein, description of reference numerals is as follows: 1 breather pipe, 2 soft cover plates, 3 protection cases, 31 first " L " shape plate, 32 " Z " shape plate, 33 second " L " shape plate, 41 lintels, 411 front vertical plates, 412 back vertical plates, 413 bottom plate, 42 lintel plates, 421 upper plates, 422 swash plates, 423 lower roof plates.

The specific embodiment

Describe below with reference to accompanying drawings embodiment of the present utility model, the utility model is further illustrated.

It is example that the drafting apparatus of take is arranged on the lintel of bulk container casing, and the utility model is described.It is only exemplary that drafting apparatus is arranged on the lintel of bulk container casing, is not intended to limit the utility model.Those skilled in the art are to be understood that drafting apparatus can be arranged on any position that is applicable to arranging drafting apparatus of bulk container casing, such as end lintel, end sill, top beam of laterally, door-plate, door crossbeam, wallboard, case top etc.

Fig. 2 arranges the schematic diagram of ventilate bulk container on lintel of the present utility model; Fig. 3 is the A-A cutaway view of the drafting apparatus of bulk container shown in Fig. 2.As shown in Figure 2, a plurality of drafting apparatuss are arranged on the lintel of container body.

As shown in Figure 3, the lintel 41 of freight container and lintel plate 42 are encircled into the hollow columnar structures that an along continuous straight runs extends.Lintel 41 is the U-shaped structure that a steel plate bending forms, and this U-shaped structure comprises front vertical plate 411 and back vertical plate 412, and the bottom plate 413 that connects two risers.Lintel plate 42 is also that a steel plate bending forms, comprise a upper plate 421, a swash plate 422 and lower roof plate 423, upper plate 421 and lower roof plate 423 along continuous straight runs extend, swash plate 422 is connected between upper plate 421 and lower roof plate 423, upper plate 421 is weldingly connected with front vertical plate 411 and back vertical plate 412, upper plate 421 is mutually concordant with front vertical plate 411, and the junction of upper plate 421 and swash plate 422 is in the outside of lintel, and upper plate 421 is wider than bottom plate 413.

Breather pipe 1 is a steel pipe, and the front vertical plate 411 of its outer end and lintel 41 is weldingly connected and is formed into air port, and its back vertical plate 412 inner and lintel 41 is weldingly connected and forms air port.Breather pipe 1 is obliquely installed, and makes its air outlet higher than the position of air intake vent, to prevent that rainwater etc. from entering in case.

Soft cover plate 2 is a thin plate, by hinge, be connected with the back vertical plate 412 of freight container lintel, be arranged on the air outlet place of breather pipe 1, and the area of soft cover plate 2 is greater than the air outlet area of breather pipe 2 to cover the air outlet of breather pipe 1, the air outlet that soft cover plate 2 covers breather pipe 1 in transportation is with sealing bulk container, prevents that steam etc. from entering in case; When unloading, air pressure inside reduces, and barometric pressure is opened soft cover plate 2.

Removable protection case 3 comprises first " L " shape plate 31, " Z " shape plate 32 and second " L " shape plate 33; first " L " shape plate 31 is welded together with the swash plate 422 of lintel plate 42; second " L " shape plate 33 is welded together with the back vertical plate 412 of lintel 41, and the upper and lower of " Z " shape plate 32 is connected by bolt and nut with second " L " shape plate 33 with first " L " shape plate 31 respectively.The part back vertical plate 412 of first " L " shape plate 31, " Z " shape plate 32, second " L " shape plate 33 and the lintel plate 42 of the part upper plate 421 of lintel plate 42, swash plate 422, removable protection case 3 is encircled into the hollow columnar structures of extending along lintel direction.This hollow columnar structures is enclosed in a plurality of drafting apparatuss that are arranged on lintel wherein.The width of the Length Ratio bulk container inside of this hollow columnar structures is narrow, to vacate a segment distance at the two ends of hollow columnar structures, the inner space of this hollow columnar structures communicates with internal container space, to keep ventilation.Removable protection case 3 can prevent that goods is directly pressed on the soft cover plate 2 of breather pipe 1, affects fanning effect.

Bulk container of the present utility model, owing to having above-mentioned drafting apparatus and can have draught head inside and outside bulk container, makes freight container inner and outer air pressure reach balance, thereby has avoided distortion or the damage of freight container.
