Description

Fluid transport container

The present invention relates to a fluid transport container that is suitably used mainly for transporting a highly viscous fluid such as grease.

Conventionally, containers used for transporting highly viscous fluids, which are so-called viscous materials such as oils and fats such as grease, fluid foods such as printing inks, adhesives, paints, and mayonnaise, and various other highly viscous materials, Tanks made of plastic or plastic were generally used.

However, this kind of tank is quite expensive, and the efficiency of transporting empty tanks and storing empty tanks when returning from the destination is inferior, and it is troublesome to clean the tank inner surface and the discharge pipe for repeated use. It was a thing.

Therefore, in recent years, a bag made of a flexible synthetic resin film or the like is used in combination with a rigid outer frame that can be folded and disassembled, and the bag is discarded after being used once. A liquid container with simplified cleaning has been proposed (for example, Patent Document 1).

In this case, in transporting a low-viscosity liquid, filling and discharging can be easily performed using the fluidity of the liquid. However, in the case of a highly viscous fluid as described above, the fluid itself Filling and discharging are difficult to perform with only fluidity. Therefore, for example, a highly viscous fluid is filled or discharged by a pumping force from an inlet / outlet port at the bottom.

By the way, when the high-viscosity fluid is discharged from the inlet / outlet portion at the bottom by the pumping force by the pump, the high-viscosity fluid is sucked and discharged by the pump from the portion close to the inlet / outlet portion. On the upper surface (liquid level) of the fluid, the top of the bag sinks from the center, and the top of the bag is drawn from the center, and part of the bag is sucked into the entrance / exit port. As a result, the discharge of the highly viscous fluid may be hindered. In particular, the fluid may remain in the peripheral portion of the bag body without being sufficiently discharged.

Therefore, the bag body can be opened and closed by projecting the flange cylinder having a long hole through which the liquid passes through the cylindrical discharge body attached to the entrance and exit of the interior body. An inner bag for a container has been proposed that prevents the mouth from being completely blocked by being sucked into the mouth (see Patent Document 2).
Japanese Patent No. 3769653 JP 2004-182275 A

By simply preventing the bag body from sticking to the entrance / exit port as described above and completely blocking it, the internal high-viscosity fluid is discharged from the vicinity of the entrance / exit port by suction by the pump. Therefore, when a flexible bag body such as a synthetic resin film is adsorbed on the outer peripheral surface of the discharge body, there is a possibility that the discharge of the fluid is hindered. In addition, there is almost no effect in promoting the discharge of the fluid in the peripheral part in the bag, and there is a possibility that the fluid remains in the peripheral part. Such a problem becomes more prominent as the viscosity of the highly viscous fluid is higher.

Further, since the proposed inner bag for a container is a bag made entirely of a synthetic resin film or the like, as the highly viscous fluid of the contents is discharged and reduced, The layers are folded and overlapped, and the fluid becomes more difficult to be discharged, and the remaining amount of fluid increases.

The present invention has been made in order to solve the above-described problems, and in particular, the structure of the container body for storing the fluid to be transported, particularly the structure of the lower body including at least the bottom, is devised and stored. Fluid that can be discharged from not only the central part near the entrance and exit but also the peripheral part at the same time, and the fluid can be discharged almost without leaving to the end Provide shipping containers.

A fluid transport container of the present invention that solves the above-mentioned problems is a fluid transport container comprising a container main body that stores a fluid and an outer frame that supports the container main body, and the container main body includes at least a bottom portion. And a lower body made of a flexible sheet material fixed to the upper portion of the lower body in a sealed state, and the lower body is made of a porous body through which fluid can pass over at least the entire bottom. It has a double wall structure with an inner wall and an outer wall made of a liquid-impermeable plate, has a gap through which fluid can flow between the inner and outer walls, and has a fluid inlet / outlet at the bottom of the outer wall. It is characterized by becoming.

This fluid transport container is mainly used to store and transport a highly viscous fluid that is a so-called viscous material such as grease. In this use, when the internal high-viscosity fluid is sucked and discharged by the pumping force of the pump from the inlet / outlet portion of the lower body in the container body, the space between the inner and outer walls of the lower body of the double wall structure in the container body Through the gap, the suction force by the pump extends over at least the entire area of the bottom, and the internal fluid is sucked substantially simultaneously over the entire area of the bottom through the inner wall made of a porous body and flows from the gap between the inner and outer walls to the entrance / exit port. Discharged.

Moreover, even if the fluid contained is a highly viscous fluid, the upper body (liquid level) of the upper body made of a flexible sheet material is locally reduced because the upper surface (liquid level) of the fluid is lowered as a result of the discharge. In addition, even if the upper body is closely attached to the inner wall due to a small amount of fluid remaining inside, there is no risk of closing the entrance port formed on the outer wall. The suction and discharge action is reliably performed to the end through the gap between the mouth and the inner and outer walls. In addition, since only the upper body is made of a flexible sheet material, even if the upper body is folded along the inner wall, there is little overlap, and the remaining amount attached to the upper body is small. Become.

In the fluid transport container, the lower body of the container main body includes a bottom portion and a side lower portion region, and an inner wall made of a porous body that allows fluid to pass through the entire bottom portion and the side lower portion region and a liquid-impervious portion. A double wall structure with an outer wall formed of a plate material can be formed, and a structure in which a gap through which a fluid can flow between the inner and outer walls can be provided.

In this case, when sucking and discharging the highly viscous fluid, the suction force by the pump extends not only to the bottom but also to the lower side region, and the internal fluid is sucked across the entire bottom and side lower region. Thus, the fluid can be sucked and discharged without a shortage even in the peripheral part far from the entrance / exit part. Therefore, the discharge of the fluid in the container body is made uniform as a whole, the lowering of the upper surface of the fluid accompanying the decrease in the fluid is averaged, and the upper body made of the flexible sheet material is not partially drawn into the fluid.

In the fluid transport container, the porous body constituting the inner wall of the lower body is made of a perforated plate or a net having a large number of apertures through which a highly viscous fluid can pass. As a result, even if the internal fluid is a highly viscous fluid, the fluid can be discharged simultaneously over the entire bottom portion or the entire bottom portion and side surface lower region. Further, when the inner wall made of the porous body is provided so as to be removable from the outer wall, the inner and outer walls of the lower body can be easily cleaned by removing the inner wall.

In the fluid transport container, a bottom portion of the outer wall of the lower body has a funnel shape inclined toward the entrance / exit port, and the inner wall forms a corresponding shape with the outer wall so as to cover the entrance / exit portion. What is provided in is preferable. That is, when the internal fluid is discharged, the fluid delivered from the opening existing over substantially the entire inner wall of the lower body is sucked from the entrance / exit port by the pumping force of the pump, and the entrance / exit port It can be reliably discharged efficiently by guiding to the part.

Further, in the fluid transport container, it is preferable that the container body is supported by the lower body being supported by a lower bottom receiving frame in the outer frame at the peripheral edge. Accordingly, the container body can be stably supported at a predetermined height position in the outer frame, and the container body can be easily provided to be removable from the outer frame.

In the fluid transport container, it is preferable that a cylindrical mouth member capable of connecting a fluid filling and discharging pipe is attached to an entrance / exit portion of the outer wall of the lower body. Thereby, the said filling and discharge | emission pipe | tube can be connected easily. Also, cleaning is facilitated by removing the filling and discharging tube.

In the fluid transport container, the upper body is fixed such that a lower end portion of a flexible sheet material is held in a sealed state via a packing with respect to a frame member attached to the upper end portion of the lower body. Is preferable. Accordingly, the upper body made of the flexible sheet material can be securely fixed to the lower body in a sealed state and used. When the upper body is damaged, the lower body can be used semipermanently by replacing only the upper body.

In the fluid transport container, the outer frame is provided with side plates that cover at least four side surfaces of the upper body of the container body. Thereby, the upper body which consists of a flexible sheet material of the said container main body can be supported and protected from the exterior.

As described above, according to the fluid transport container of the present invention, the lower body including the bottom of the container main body, or the lower body including the bottom and the side surface lower region, the inner wall made of a porous body through which the fluid can pass and the liquid non-permeable. The inner wall of the housed by having a double wall structure with an outer wall made of a conductive plate material, having a gap through which fluid can flow between the inner and outer walls, and providing a fluid inlet / outlet at the bottom of the outer wall Even if it is a highly viscous fluid having a high viscosity, it can be discharged simultaneously not only from the central part near the entrance / exit port but also from the peripheral part, and the fluid can be discharged smoothly. Moreover, as the internal fluid decreases, the upper surface of the fluid descends substantially evenly, and the upper and lower openings made of a flexible sheet material follow the above and the entrance / exit port is folded. The fluid can be discharged without being sucked into the part and hardly remaining until the end.

Next, the best mode for carrying out the present invention will be described based on an embodiment shown in the drawings.

FIG. 1 is a cross-sectional view showing an outline of an assembled state of a fluid transport container A according to the present invention, FIG. 2 is an enlarged cross-sectional view of the vicinity of the entrance / exit part, and FIG. 3 is a connection part between a lower body and an upper body of the container body 4 is an enlarged cross-sectional view of a portion for receiving and supporting the lower body, FIG. 4 is a perspective view showing a section of the container body with a part cut away, FIG. 5 is a perspective view with a part cut out of the outer frame, and FIG. It is sectional drawing of the state near discharge completion.

The fluid transport container A according to the present invention includes a container main body 1 that stores a fluid to be transported, for example, a highly viscous fluid, and an outer frame 3 that supports the container main body 1. The pallet part 4 is integrally provided.

As shown in FIG. 4, the container body 1 is formed of a material having rigidity such as metal and includes a lower body 10 including at least a bottom 10a, preferably a bottom 10a and a side lower region 10b continuous therewith. The lower body 10 includes a lower body 10 and an upper body 20 made of a non-liquid-permeable flexible sheet material fixed to the upper end of the lower body 10 in a sealed state. The entrance / exit part 11 is provided in 10a. Reference numeral 5 denotes a fluid filling and discharging pipe connected to the inlet / outlet port 11.

The upper body 20 has a cylindrical shape with a side surface upper region 20b and a top portion 20a, and a mouth portion 21 with an air vent with a cap is provided on a part of the top portion 20a. Examples of the non-liquid-permeable flexible sheet material constituting the upper body 20 include a single-layer or multi-layer sheet of a synthetic resin film such as a polyethylene film, and tarpaulins in a form in which these sheets are reinforced with fibers. Water-resistant sheets, composite sheets made of combinations of these with other material sheets, or various non-liquid-permeable and flexible sheet materials such as rubber bag materials, etc. It is preferable to use a sheet material that can withstand use.

The lower body 10 has an inner / outer double wall structure, and the inner wall 12 is a lower body comprising at least a bottom 10a, preferably the entire lower body 10 comprising the bottom 10a and a side lower region 10b as shown in the figure. A porous body through which a highly viscous fluid to be transported can pass, that is, a porous body having many openings through which the fluid can pass, and the outer wall 13 has moderate rigidity such as a stainless steel plate or other metal. It is formed liquid-tight by a plate material, and has a required gap S between the inner and

outer walls

12 and 13 through which a highly viscous fluid can pass. The gap S varies depending on the open area ratio of the porous body constituting the inner wall 12 and the viscosity of the fluid, but is, for example, about 10 to 30 mm, preferably about 15 to 25 mm.

The inner wall 12 is attached to the inner surface of the outer wall 13 so as to be removable and to hold the gap S. As a means for this, a nut member 14 serving as a spacer is fixed to a required portion in the bottom and side lower regions of the inner surface of the outer wall 13 by means such as welding, and the inner wall 12 is attached to the nut member 14. The inner wall 12 is fixed by a screw member 15 such as a bolt that penetrates and is screwed, and the inner wall 12 can be separated from the outer wall 13 by removing the screw member 15. The inner wall 12 can be integrally formed of a porous body, but it is desirable to divide the inner wall 12 into a plurality of parts such as a bottom portion and four side surface lower regions in order to facilitate separation from the outer wall 13.

As the porous body constituting the inner wall 12, a perforated plate or a net body such as a punching metal in which a large number of apertures 12a through which a fluid to be transported, in particular, a highly viscous fluid can pass, is formed is preferably used. Among them, a metal perforated plate such as a punching metal or the like in which the round holes and the square holes are arranged in at least one direction in the vertical and horizontal directions, or in a staggered arrangement, a parallel arrangement of long holes, and a parallel arrangement of deformed holes is particularly preferably used. Of course, other materials such as a perforated plate, a metal net, a cage net, a rigid synthetic resin net, and various other perforated plates and nets can be used.

The aperture ratio of the apertures 12a of the porous body, that is, the pore diameter, the arrangement pitch, the aperture density, and the like can be appropriately set according to the viscosity of the fluid to be transported. For example, when the holes 12a are punched metal having a round hole with a diameter of 10 to 40 mm, the parallel pitch is 20 to 50 mm and the hole interval is 5 to 30 mm. Of course, it is also possible to implement with other hole diameters and arrangements than those described above. The porosity of the porous body need not be the same over the entire surface of the lower body, and the porosity can be partially varied, for example, by varying the aperture ratio between the central portion and the peripheral portion.

The entrance / exit port 11 is provided at the center of the bottom of the outer wall 13. In the case of the figure, the outer wall 13 has a funnel shape in which the bottom portion is inclined in a reverse quadrangular pyramid shape from four directions toward the entrance / exit port portion 11, and the inner wall 12 made of the porous body is the outer wall 13. And the entrance / exit port 11 is provided so as to cover the whole while maintaining the gap S between the port 11 and the entrance / exit port 11. That is, the bottom 10a of the lower body 10 has a funnel shape, and the fluid passing through the inner wall 12 easily flows into the inlet / outlet port 11 when the fluid is discharged. The inclination angle of the bottom portion 10a can be appropriately set in consideration of the fluid flow effect, etc., but the storage efficiency becomes worse as the inclination angle becomes larger, and the flow effect cannot be obtained as the inclination angle becomes smaller. In the upper part, the inclination angle with respect to the central part having the entrance / exit port 11 is 15 ° to 45 °, preferably 20 ° to 30 °.

As shown in an enlarged view in FIG. 2, a cylindrical connection port member 16 for connecting the filling and discharging pipes 5 is integrally attached to the access port 11 by means such as welding. The tube end portion of the mouth member 16 and the tube end portion of the filling and discharging tube 5 are brought into butt contact with each other via a packing (not shown) by a clamp-type connecting means 7. To be connected to. The filling and discharging pipe 5 is provided with an open / close valve 52 on an elbow-shaped pipe body 51 and a fitting 53 to which other pipes or hoses (not shown) having a pump for pressure feeding can be connected. Become. The filling and discharging pipe 5 is connected to the mouth member 16 and fixed on the pallet portion 4 by a fixture 6 including a pressing member.

The rising height H of the lower side surface region 10b of the lower body 10 is in a range of ½ or less of the side surface height of the container body 1 in consideration of the effect of discharging the fluid at the peripheral portion in the container body 1 and the like. Thus, in a state where the internal fluid is almost completely discharged, the sheet material constituting the upper body 20 can be appropriately set so as to be in contact with the entire inner surface of the inner wall 12. The height of the side surface of the container body 1 is set to 1/5 or more and 1/2 or less so that the sheet material of the upper body 20 is not excessively overlapped in a state where the sheet material is in contact with the inner surface of the inner wall 12. It is preferable to keep it.

That is, since the porous body opening 12a constituting the inner wall 12 of the lower body 10 can simultaneously discharge at least the entire area of the bottom 10a, the rising height H from the bottom edge of the side surface lower region 10b of the lower body 10 However, even if the height of the side surface of the container body 1 is lower than 1/5, the effect of uniform fluid discharge can be obtained. However, if the height H of the side surface lower region 10b is too low, the upper portion made of the flexible sheet material is used. In the state where the body 20 is in close contact with the inner wall due to the discharge of the internal fluid, there is too much room and the overlap increases, so the above range is more preferable.

As means for fixing the upper body 20 to the upper end of the lower body 10 in a liquid-tight manner, as shown in an enlarged view in FIG. 3, the upper end of the side lower region 10 b of the lower body 10, particularly the upper end of the outer wall 13. A mounting frame member 18 is fixed by welding means, and a sealing material 19 such as rubber is disposed on the upper surface of the frame member 18 so that the lower end portion 22 of the flexible sheet material constituting the upper body 20 is sealed. It is sandwiched between the material 19 and the pressing frame member 23 and fastened by the screw fastening means 24 at a predetermined pitch interval (for example, 50 mm interval) in the length direction, and the fastening by the screw fastening means 24 is released. The sheet material constituting the upper body 20 can be replaced. As the screw fastening means 24, in the case shown in the figure, a screw shaft portion 24a is projected from the frame member 18, and the sealing material 19, the lower end portion 22 of the sheet material, and a pressing frame are provided with respect to the screw shaft portion 24a. The members 23 are provided so as to be fitted to each other at the engagement hole portions and tightened by the nuts 24b. It can be fixed by using other various fixing means such as an adhesive means or a rivet type stop means.

The container body 1 may be configured by being integrally incorporated in the outer frame 3 at a rigid lower body 10 portion, and the bottom edge of the lower body 10 may be a bottom receiving frame of the lower body 10. It can also be provided so as to be detachable with respect to the outer frame 3 so as to be supported by 31. The illustrated embodiment shows a case where the container body 1 is incorporated into the outer frame 3 and is detachable.

In the illustrated embodiment, the outer frame 3 is connected to the bottom receiving frame 31 for receiving the lower body 10 of the container main body 1 and the bottom receiving frame 31 on the pallet portion 4. The

side plates

32a, 32b, 32c, and 32d that cover the four side surfaces of the upper body 20 and the upper frame 33 as an upper lid that is detachably attached to the assembled side plates.

In the bottom receiving frame 31, a horizontal frame-like receiving frame member 35 is bridged between the supporting

columns

34, 34 along the four side surfaces at the required height positions of the supporting columns 34 erected at the four corners of the pallet portion 4. It has a frame shape. And as the said receiving frame member 35 expands and shows in FIG. 3, the cross-sectional view which has the receiving plate part 35a which protrudes diagonally corresponding to the inclination of the bottom part 10a of the said lower body 10 inward from an inner lower part. The lower plate 10 of the container body 1 that is dropped into the outer frame 3 from the upper side and set by the receiving plate portion 35a can be supported by the peripheral edge portion by the receiving plate portion 35a.

In the case of the figure, the support pillar 34 extends above the receiving frame member 35, and the side frame portion 36 provided at the upper end thereof is substantially the same as the upper end of the lower body 10 of the container body 1 received and supported as described above. It is provided to be at the same height. The recording plate portion 35a can be provided so as to support substantially the entire surface of the bottom portion 10a of the lower body 10 except for the entrance / exit port 11, but if the lower body 10 is a rigid material such as metal, It is not necessary to support substantially the entire surface of the bottom portion 10a, and the bottom portion 10a can be implemented so as to receive the peripheral portion of the lower body 10 as shown.

In any case, when the lower body 10 of the container main body 1 is received and supported on the bottom receiving frame 31 as described above, the lower body 10 is adjusted so as to prevent rattling or lifting of the received lower body 10. It is desirable to provide a lock means (not shown) that can be engaged and disengaged with the outer frame 3.

The four

side plates

32a, 32b, 32c, and 32d of the outer frame 3 each have an inner surface formed of various types of boards such as a metal plate, a synthetic resin plate, or a particle board, or other rigid members, inside the frame member. The panel body is stretched so as to be provided, and is provided to support the upper body 20 of the container body 1 from the outside. Each of the

side plates

32a, 32b, 32c, 32d is connected to the upper portion of the bottom receiving frame 31 and erected, and adjacent side plates are connected to each other to be assembled into a planar rectangle. The

side plates

32a, 32b, 32c, and 32d are normally connected to the bottom receiving frame 31 in a separable manner.

In the case of the figure, one of the four

side plates

32a, 32b, 32c, 32d, for example, one of the left and right side plates 32b as viewed from the front, can be bent outwardly with respect to the side frame portion 36 through a hinge portion 37. The container main body 1 can be set and cleaned, or the upper body 20 of the container main body 1 can be replaced from the open portion.

The

side plates

32a, 32b, 32c, and 32d are folded inward by sequentially changing the height with respect to the side frame portion 36 that is substantially at the same height as the upper end portion of the lower body 10 of the container body 1. It is also possible to configure such that the container body 1 can be folded with a low bulk while the container body 1 is set when returning or storing an empty container from a transportation destination. The

side plates

32 a, 32 b, 32 c, and 32 d are provided so as to be connected to the receiving frame member 35 and cover the side surfaces of the bottom receiving frame 31, omitting the side frame portion 36 of the bottom receiving frame 31. It can also be implemented.

The fluid transport container A configured as described above is used for transporting fluid foods such as grease, printing ink, adhesives, paints, mayonnaise, and other various fluids, especially highly viscous fluids. The container body 1 composed of the lower body 10 having a double wall structure and the upper body 20 made of a flexible sheet material connected to the lower body 10 is inserted into the outer frame 3 assembled in advance in a predetermined shape. The lower body 10 is set so that the peripheral edge of the lower body 10 is supported by the receiving frame member 35 provided on the bottom receiving frame 31 of the outer frame 3. A filling and discharging pipe 5 is connected in a liquid-tight manner by a clamp-type connecting means 7 to a mouth member 16 provided in the entrance / exit part 11 in the bottom part 10 a of the lower body 10. It is fixed to.

The filling of the fluid to be transported, particularly the highly viscous fluid, is carried out by being pumped by a pump (not shown) provided in a pipe connected to the filling and discharging pipe 5 and filled and stored in the container body 1. At this time, the fluid pumped by the pump enters between the inner wall 12 and the outer wall 13 of the double wall from the inlet / outlet port 11 at the bottom 10a of the lower body 10 forming the double wall structure of the container body 1, It spreads to the peripheral part through the gap S between the inner and

outer walls

12 and 13, and is sent and filled into the container body 1 through the openings 12a of the inner wall 12 made of a porous body over the entire bottom part 10a and side surface lower region 10b. With this filling operation, the upper body 20 made of the flexible sheet material in the folded state swells along the

side plates

32a, 32b, 32c, and 32d on the four side surfaces of the outer frame 3, and is finally filled. It is held in a swelled state as shown in FIG. 1 by a fluid (not shown).

And when discharging the fluid of the contents at the transport destination, it is sent out by the suction force of the pump for pumping provided in the pipe connected to the filling and discharging pipe 5. At this time, when the fluid is sucked from the inlet / outlet port 11 of the lower body 10 of the container body 1 by the suction force of the pump, the suction force by the pump is generated between the inner and

outer walls

12 and 13 of the double wall structure. The gap S extends to at least the entire area of the bottom 10a, in the case of the embodiment, to the entire area of the lower side area 10b, and the internal fluid is simultaneously sucked through the openings 12a of the inner wall 12 made of the porous body. It flows from the gap between them to the entrance / exit, and is discharged.

Therefore, even if the contained fluid is a highly viscous fluid, the upper surface (liquid level) of the fluid in the container main body 1 is reduced so as to drop substantially at the same time due to the discharge. The top body 20a of the upper body 20 made of the flexible sheet material descends so as to collapse, but the upper body 20 made of the flexible sheet material is not sucked locally. In addition, as the upper surface of the internal fluid becomes lower than the height of the lower side surface region 10b of the lower body 10 and the remaining amount decreases, the upper body 20 moves to the side surface lower region 10b and the bottom portion 10a of the lower body 10. At this time, suction is performed along the inner surface, and the entire inner wall 12 of the lower body 10 is sucked at this time. Even if the hole 12a is blocked, the entrance / exit 11 formed in the outer wall 13 is not blocked. Therefore, a suction / discharge action is performed from the other opening 12a through the gap S between the inner /

outer walls

12 and 13 from the entrance / exit port 11, and as a result, the fluid can be discharged satisfactorily until the end. Almost no residue.

In addition, when the fluid transport container A is repeatedly used, the inside of the container body 1 can be washed and reused according to the contained fluid, or can be reused without washing. For example, in the case of grease or the like, it can be used repeatedly without cleaning the inside of the container body 1.

The present invention can be suitably used for transporting fluid food such as grease, printing ink, adhesive, paint, mayonnaise and other highly viscous fluids.
