Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to large containers configured to be stackable. A typical example of this large container is a silo. The large container includes a main body, a head, and seven lunges arranged along the central axis of the large container. The head is attached to the upper part of the main body by welding, and has an insertion opening at the upper part for storing items to be stored in this large container, and the shape is a conical shape that becomes smaller as it goes upward. . The flange is attached by welding to the lower end of the main body and serves to attach to the main body other parts forming the large container, such as a funnel for discharging the contents.

Large containers of the above type are widely known (eg West German patent specification DID-PS2159602).

Since large containers can be stacked, the cost of transporting the large containers from the manufacturing site to the installation site is extremely low. During the above-mentioned transportation, a number of main body parts each having a diameter of several meters and a length many times the diameter, each having a head at one end and a flange at the other end, are fitted one on top of the other. This is because it can be transported by If you do this, it's a tractor.

When large containers are transported using freight trains, ships, etc., they can be transported without actually requiring a large space. In comparison, it is clear that a large amount of space would be required if the above-mentioned members were moved separately without stacking them (for example, U.S. Patent Specification 1tJs-ps 3023019 and 410981).
9).

The same applies when transporting a large cylinder-shaped silo using a transport device.

Large containers equipped with a closing plate that closes the opening are also known. In this case, the opening is closed by a closing plate biased by a closing means using a spring. When the differential pressure between the inside and outside of the large container increases beyond a predetermined value, the closing plate is suddenly pushed toward the low pressure side. Many countries have regulations in place for large containers that pose a risk of internal pressure exceeding, exceeding, or lower than the specified pressure.According to these regulations, large containers such as those mentioned above It is prescribed that a so-called rupture disc, a so-called closing disc that can be ruptured by high pressure, should be used. A disc-shaped closing plate held by a rubber fastener has also been proposed. By attaching this closing plate to the opening of the container, the closing plate is explosively removed from the wall of the large container when the pressure inside the large container exceeds an allowable pressure. When using such a closure plate, methods have been considered to prevent the closure plate from popping out when the pressure inside the container is released. However, the disadvantage of adopting such a structure to prevent pop-out is that it becomes necessary to provide means for holding a series of closing plates corresponding to various predetermined pressures and applying appropriate preloads to them. . For this reason, the use of large containers that could be stacked and transported was almost impossible. In order to avoid such drawbacks, a left bursting disc type closure plate was first installed on a large container after it was transported to the construction site of the large container. However, this method was also not preferable. This is because, in this case, it becomes necessary to dispatch a person skilled in container manufacturing to the location where large containers are installed. That is, as mentioned above, it is difficult to attach the closing plate with a predetermined pressure unless it is done by an experienced person.

Dispatch of such skilled personnel generally has the disadvantage of increasing costs.

The problem to be solved by this invention is to
The object of the present invention is to improve the large stackable containers described at the beginning of ``Detailed Description of the Invention''.

This improvement is to allow large containers to be stacked and transported to a customer site, ie, a construction site, regardless of the structure in which a rupture disk-type closure plate is attached to large containers at a manufacturing factory.

The invention of this application that solves the above problems is as follows. That is, in the large container of the present invention, a neck is formed between the head and the main body. This neck is formed between the joint with the main body and the joint with the head, and forms a larger angle with respect to the central axis of this large container than the conical main body, and contracts toward the head. It has a shape that

The neck is provided with an opening, and the opening includes a closing plate that at least partially ruptures and rapidly separates when the pressure inside the large container exceeds or exceeds a predetermined pressure range. is arranged to close said opening.

The neck is formed to be inclined at a larger angle with respect to the central axis than the main body, so when the closing plate is assembled in an operable state, it is necessary to stack large containers. A gap is formed between adjacent large containers.

Therefore, the closure plate can be attached to the large container at the manufacturing site and adjusted to perform the desired function. Since such a manufacturing method can be used, the adjustment of the closing plate can be carried out with sufficient precision at the manufacturing site using a specified measuring device, and if necessary, highly skilled personnel can be used. It also becomes easier. Furthermore, many large containers can be assembled and tested one after another, which is convenient for rapid and smooth manufacturing.

Although the above description of the large container is for a standard container, various modifications can be made depending on the purpose of use, for example. Next, let's look at an example.

For example, one example of this is to use an elastic flang, for example made of rubber, to directly close the opening in the neck against at least one bend. At this time, one side of the clamp member is rotatably attached to one of the neck and the closure plate, and the other side is provided with at least one member extending beyond the clamp member so as to press against the other of the neck and the closure plate. Preferably, there are two arms.

However, the rotation of the above-mentioned arm is always prevented and the closing plate is placed in close contact with the opening of the neck, and when a pressure that is too high or below the specified pressure is generated in the large container, the one that allows the rotation of the above-mentioned arm is cut off. is provided.

Another possible modification is that, in order to make the closure plate easier to tear off, there may be a notch in the middle between the edge of the opening in the neck and the outer edge of the closure plate to make it easier to tear. A clamping member is provided at the weakened portion of the clamping member. In this case, it is preferable that the weakened portion be provided at a position that can be reached from the outside so that damage occurs along this weakened portion. The most advantageous method is to use a single ring-shaped clamping part which is provided almost uniformly and completely surrounding the closing plate. In addition, as the material of the clamp member, when excessive pressure is applied instead of rubber, there is no tearing between the neck and the closing plate, and the overpressure is always released through the opening formed in the neck based on the shearing of the shear bin.
An elastically bending material may be used, as is done on one side of the closure plate.

As an alternative to the shear bin described above, it has a function that does not restrict the movement of the arm when the applied pressure exceeds a predetermined tolerance value, but stops the movement of the arm when the pressure is below a predetermined value. Other percentages may also be used.

Next, this invention will be explained in detail. FIG. 1 shows a silo which is an embodiment of a large container according to the present invention. The large container has a main body 1 made of aluminum or steel. It is assembled by combining an annular flange 6, a funnel part 13 for taking out the contents of the container, a ring-shaped base part 7, etc. The large container is mounted by a well-known method on a base 10 provided at a predetermined location at a predetermined construction site, such as a chemical factory. Main body part 1
An insertion opening 1 is provided at the top of the
and reinforcing members 12.12 in two, three or more places.
A is provided. A rope, such as a steel rope S or a chain ioo, is coupled to the reinforcing member 12.12a. The above-mentioned ropes and chains are used when lifting the large container or the main body 1 or when assembling the large container. A flange 4 and an auxiliary ring 2, which is arranged at a predetermined distance from the flange 4 and used when transporting this large container, are provided at the lower end of the main body part 1. The auxiliary ring 2
is used together with the strut 5 as a sweeper. The strut 5 is attached to the outside of the main body 1 so as to extend from the flange 4 to the auxiliary ring 2. Flange 4. The annular flange 6 and the base 7 are connected by gel 8. =1
The large container shown in the figure shows the normal condition when it is erected at a construction site. A discharge opening 9 is provided at the bottom of the funnel portion 13. As shown in Fig. 1, when in use, this large container is constructed so that the central axis 14 points almost vertically, and its outer peripheral surface tapers upward, forming a small angle β with the vertical line. It has a conical shape. The angle β corresponds to the apex angle of the conical shape. A neck portion 20 having a conical shape is welded between the main body portion 1 and a conical head portion 21 having a larger apex angle than the main body portion 1 . The apex angle of the conical shape of the neck portion 20 is formed to have a value between the conical apex angle of the main body portion 1 and the conical apex angle of the head portion 2 . The neck 20 is provided with an opening that supports a closing plate 22 that pops out explosively.

Figure 2 shows the main body part 1. A plurality of container bodies 50 each consisting of a neck portion 20 and a head portion 21 are assembled to be suitable for transportation. As shown in FIG. 2, a plurality of container bodies 50 of the large container are assembled so that the central axes 14 are coaxial, and the right end portion stacked on the innermost side and opening with the largest cross-section is located on the transporter. The lower end protrusion 19 of the transporter 16 is placed on the rail 17 and can move substantially horizontally along the central axis of the container body 50. −
The living body parts 1d stacked on the inner side are supported by the holding member 18.

Therefore, even if a plurality of container bodies 50 are stacked and supported as shown in FIG. 2, the thin end portions will not sag downward. The container body 50 is arranged so that the center axis 14 faces in the horizontal direction, and the reinforcing portion 12h of the container body 50 at the outermost side of the stack is located at the top of the head 21 and the top of the flange 4. , is located. A lifting part side 83 such as a copper wire or chain 100.0 is connected to the reinforcing member 12a attached to the head 2, and the reinforcing member 1 of the flange is connected to the reinforcing member 12a.
A lifting member S4 similar to the lifting member 83 is also coupled to 2a. The lifting members 83+84 are used to lift and move the plurality of stacked container bodies 50 shown in FIG. 2.

FIG. 3 shows a state in which six container bodies are all set up vertically. 1 to Ie indicate six stacked main bodies. The central axes 14 of the living body parts 1 to 1e are oriented substantially vertically as described above. The lower ends of the main body parts 1 to Ie are formed to have the largest cross section, and seven flanges 4 and an auxiliary ring 2 are provided here at predetermined intervals. With the above structure, the auxiliary ring 2 comes into contact with the seven runs 4 of the living body parts to be stacked next, and works to maintain the distance in the center axis direction between the two main body parts at a predetermined value. A reinforcing member 12a is provided at the minimum diameter portion at the top of the main body portion 1, and serves as a ring for use in suspending the main body portion 1 by a hoist.

The reinforcing member 12m is inserted into the inner part of the neck 20 as shown in FIG. 4c.
111 and is welded, and protrudes upward through the head 21. Furthermore, by using the large reinforcing member 12 shown in FIG. 4a, even if the container body 50 is heavy, it can be safely and reliably lifted or transported.

FIG. 4a shows the upper part of the closing plate 22, a part of the neck part 20 above it, and a part of the head part 2 which continues thereon, together with a cross-section. Further, FIG. 4b shows a lower part of the closing plate 22, a part of the neck part 20 below it, and a part of the main body part 1 provided in the F direction following these parts. The closing plate 22 is attached to seal the opening in the neck 20, as will be explained later.

The head 21 is formed to have an angle a of approximately 15° with respect to the horizontal plane 3θ, as shown in FIG. 4a. The cross section, ie, the horizontal plane 30, which is substantially perpendicular to the center axis 14, is of course substantially perpendicular to the vertical line 32, which is substantially parallel to the center axis 14. Further, the reference numeral 1x in FIG. 4b indicates a part of the cross section of the main body part 1 which is located just outside the main body part 1 when the main body parts 1 are stacked as shown in FIG. As can be seen from FIG. 1, the main body portion 1x forms an angle β with respect to the central axis 14 of the main body portion 1 (FIG. 1). As shown in FIG. 4b, the outer edge 21x of the head 21 extends in the radial direction beyond the welded joint 24 with the upper end of the neck 20. is a plate-shaped reinforcing member 12
is attached by welding. The reinforcing member 12 is connected by a chain 100 to a handle 25 attached to the closing plate 22 by a known method such as welding. As shown in FIGS. 1 and 4c, the lifting member S is connected to the reinforcing member 12.
The position at which the connector m is attached is determined approximately above the coupling portion 24. The neck portion 20d has an opening on its side, and a clamp member 31 in which the closing plate 22 is made of an elastic material such as rubber is attached to the edge surrounding the opening, and the closing plate 22 is attached to the clamp member. The above installation situation is the 5th
．． This is explained in detail in Figure 6.7. A handle 25 is attached to the outside of the closing plate 22 as described above, and a handle 25 is attached to the outside of the closing plate 2 at a position close to the edge.
An arm support 26 is welded. The arm support 2
An arm 23 is attached to 6. This arm 23 is
It extends beyond the clamp member 31 to the upper part of the closing plate 22, and an adjustment part 28 is attached to the tip thereof. The adjustment portion 28 includes a screw, and when the screw is screwed in, the closing plate 22 is pressed toward the inside of the neck portion 20 .

The peripheral wall of the neck portion 200 is inclined at a larger angle with respect to the central axis 14 than the peripheral wall of the main body portion 1.
A container body 50 as shown in Figure b! ! ! Jt section 20
The distance between the main body portion 1x of the container main body stacked adjacent to the outside of the container main body can be designed to be sufficiently large.

The distance M shown on the left side of FIG. 3 is determined by the relationship between the conical shape of the main body portion 10 and the conical shape of the neck portion 20 having a larger apex angle than the conical shape, that is, the inclination angle of the outer periphery of both parts with respect to the central axis 14. . That is, in FIG. 4b, the interval M is formed between the neck 20 extending from the living body part 1 and the main body part 1x surrounding the outside thereof, and narrows downward.
An annular space 33 with a generally triangular cross-section that widens upwards holds the closing plate 22 and provides a pre-pressure mechanism, namely the arm support 26. The arm 23 and the adjustment part 28 can be accommodated, and these members 26, 23 can be accommodated.
．． It is set to such an extent that it does not interfere with the operation of 28. A large number of container bodies 60 formed in this manner can be stacked one after another without any problem as shown in FIG.

As clearly shown in Figure 4b, the main body parts 1. The lower arm support 26 (the upper arm support 26
(shown in FIG. 4a) and the adjacent main body portion 1x of the container body, it is possible to leave a distance aztl- at least comparable to the above-mentioned distance a1. The adjustment part 28 and the handle 25 attached to the upper part of the neck part 20 and the closing plate 22 shown in Fig. 4a are arranged in the upper wide part of the annular space 33 (the living body part 1x is omitted in Fig. 4a). ), and the distance a! from the main body part 1x! A much larger spacing is formed. Note that the angle α defining the annular space 3.9 shown in FIG. 4b is approximately 4. Note that the joint portion 27 between the neck portion 20 and the main body portion 1 is formed by welding.

A portion of the neck 20 is shown in FIG.

A head 21 whose upper end is closed is welded to the neck 20. This construction is commonly used in the construction of silos, and the neck 20 is provided with an opening of approximately a few square meters, which opening is closed by a closing plate 22 which ruptures when excessive pressure is applied. The outer periphery of the closing plate 22 is inserted into a space formed in a clamp member 31 provided along the outer periphery of the nucleus. A part of the above insertion situation is shown in FIG. In this figure, the edge 29 of the neck 20 is inserted into the space from the left, and the edge of the closing plate 22 is inserted from the right into a space provided in the clamp member 31 separately from the space. . Since the clamp member 31 connects the closing plate 22 and the neck 20 in a sealed state, rain or seawater will not enter the silo. In Figures 1 and 2, ° is
Although the position of the clamp part '#310 is shown, the present invention is not limited to this, and the closing plate 22 may be attached to an appropriate position depending on the purpose. In addition to attaching the closure plate 22 as described above, the large container of the invention uses an arm 23 which acts in this way for the attachment of the closure plate 22.

As shown in FIG. 6, the left end of the arm 23 is rotatably attached to an arm support 26 having a U-shaped cross section by a shaft 37. The arm support 26 is welded to the neck 20. The arm 23 extends beyond the clamp member 31 and substantially parallel to the neck 20, and is provided with an adjustment portion 28 with a screw at its tip reaching the closing plate 22. By rotating the screw, its tip can move forward and backward relative to the closing plate 22. The tip of the screw is formed so that it can remain stationary when pressed by an external force regardless of the rotation of the screw. C marked on the right end of FIG. 6 indicates the distance between the upper surface of the arm 23 and the outer surface of the closing plate 22 (the upper surface in FIG. 6). When the arm 23 can freely rotate around the shaft 37, the distance cl/i can be freely changed by rotating the screw of the adjusting section 28. 6th
Reference numeral 15 in the figure indicates a pin that is cut with a predetermined shearing force.

The pin 15 is attached to the arm 23 and the arm support 26 combined with the arm 1, within a distance +A from the shaft 37 that rotatably supports the arm 23,゛It acts to stop the rotation of the arm 23 about the axis 37.The relative relationship between the distances A and B is the magnitude of the force required to cut the pin 15 and the closure plate. In a practical example, the distance A is determined at the 70 end, and the distance A is determined by the relative relationship between the point at which the adjustment part 28 presses the closing plate 22tl and the rotation axis 37 of the arm 23. The distance B is determined to be approximately 300. Also, the screw that belongs to the 1.1 joint 28 and presses the closing plate 22 has a thread shape of M12, and the bottle 15 has an ilt diameter of 6.
Made of fi aluminum. The arm support 26 is a U-shaped steel part with a thickness of 4 mm, and its dimensions are 40 x 5.
It is 0x40wm. Further, the arm 23 is similarly formed with a U-shaped part made of steel, and the U-shaped arm 230 has a U-shaped part on the inside of both legs.
The outer sides of both legs of the letter-shaped arm support 26 are joined at one end to reduce rattling. Distance G on matatasu diagram 6
is the length between the position of the axis 37 and the neck edge 29,
The width of the arm 23 is determined to be approximately 120 mm, the width of the arm support 26 is determined to be 50 mm.

For example, by screwing in the screw of the first section 28, the force with which the arm 23 presses the closing plate 22 can be adjusted.

If the pressure inside the large container becomes too high, the large force exerted on the closure plate 22 will cause the adjustment portion 28. It is transmitted via the arm 23 and the bottle 15 to the arm support 26 and the neck 20. As a result, when the shearing force applied to the bottle 15 exceeds the permissible limit, the bottle 15 is cut, and the arm 23 is released from the position restricted by the bottle 15 and becomes able to rotate about the shaft 37f. In this state, arm 2
3 does not exert any force on the closing plate 22, and the closing plate 22 is moved away from the clamp member 3, and therefore from the neck 20.
This results in the person being pushed away from the body. That is, the closing plate 22, which is ruptured by overpressure, acts as a kind of safety valve and can prevent damage to the large container. The closing plate 220
The function as a safety valve is determined by the screw-in level ME of the adjustment part 28.
This is easily done by adjusting 'f. Further, the cylindrical bottle 15 passes through the arm 23 and the arm support 26 at both ends. A safety ring l5a (Fig. p. 7) is fitted into the penetrating portion of the bottle 15, and the clamp ring 15g functions to prevent the bottle 15 from being pulled out.

Further, as shown in FIGS. 6 and 7, a long groove JJX is formed on the side of the clamp member 31 that receives overpressure, and the chain length flJ
31 x acts to facilitate the closure plate 22 being pushed out by the applied overpressure.

The above description is a typical embodiment of the present invention, and various other modifications are possible. For example, the adjustment section 2 in Fig. 6
One example of this is to make it adjustable so that the position where the screw 8 presses the closing plate and the distance between the bins 15 can be changed.
