Description

PNEUMATICALLY FILLABLE CONTAINER The invention relates to a pneumatically fillable container made of flexible, airtight material, for granular, free-flowing material, with suspension devices for mounting on a support frame, with a funnel-shaped outlet that merges into an outlet connection, with a filter ceiling delimiting an air space below the container ceiling , with a filling line that ends in the center of the filling space below the filter ceiling, and with a ventilation opening that is arranged in the air space between the filter ceiling and the container ceiling.

Such a container is known from DE-GbM 8203988, published on July 1st, 1982. The container is suspended in a support frame and has a horizontally stretched filter ceiling at a distance from the container ceiling, through which the conveyed air, which has entered the filling chamber via the filling line, can enter the intermediate space between the filling chamber and the container ceiling and is removed through the ventilation opening provided in the container ceiling . The filling line is fed in parallel above the tank ceiling, is angled in the middle of the tank ceiling and passes through the tank ceiling and the filter ceiling in the vertical tank axis, opening out just below the filter ceiling. This is necessary because the filter cover is inflated with pneumatic filling. Since the ventilation opening must not be laid through the filter ceiling, the ventilation opening is provided in the immediate vicinity of the filling line in the container ceiling, so that the section of the filling line provided in the space serves as a spacer for the filter ceiling.

Containers of this type, in particular storage containers for coal, usually have to be accommodated in rooms of limited height, especially in very low basement rooms. On the other hand, of course, is as large as possible Capacity of the container is desirable, for example, to accommodate the entire amount necessary for a heating period. The usable height of the container is determined by the slope angle of the filling material, which is also decisive for the emptiness. The maximum usable container volume therefore corresponds to two cones with the base facing each other.

These containers can, for example, be part of pourable fuels, as are described, for example, in DE-OS 32 05 146. In the process, malfunctions occur repeatedly, which, in contrast to pressure conveyors, cannot be remedied by the suction conveyor system, which leads to bridges forming in the container outlet, blockages in the suction lines, since these were not completely emptied when the conveyance was interrupted, etc. These malfunctions are usually corrected arduous since, for example, clogged lines can only be emptied after complete disassembly.

The invention has now set itself the task of significantly increasing the capacity of such a container while maintaining the overall height.

Furthermore, the container should be provided with a discharge device, in which malfunctions are largely excluded and troubleshooting is made possible by easy dismantling in the simplest possible manner.

The increase in the capacity of such containers can be achieved, for example, by arranging the filter ceiling to rise towards the filling opening of the filling line. If the filter ceiling is braced horizontally, the vertical distance from the slope line of the filling material becomes with increasing distance from the vertical axis of the container greater. The filter cover can therefore be attached to the side wall in the space remaining outside the upper cone, ie deeper than before, and pulled up to the filling line. This results in the possibility of arranging the end of the filling line higher, so that its section penetrating the air space is shortened and the usable height is increased. The filling opening of the filling line can be arranged, in particular, at the smallest possible distance to a level that limits the overall height, for example the room - in particular the basement ceiling - if the ventilation opening of the air space is arranged in the region of the upper edge of the container. If the filter ceiling rises towards the center, its distance from the top edge is greatest, so that the vent opening cannot be closed even when the filter ceiling is inflated to the maximum. In this embodiment, the filter cover can therefore even be connected to the container cover in the peripheral region of the incoming filling line. In a vertical step through the container, the maximum distance from the filter ceiling to the top edge, in the area of which the ventilation opening is located, represents the height on the hypotenuse of a right-angled triangle in which the hypotenuse of the filter ceiling and the two cathets correspond to the edge-near sections of the container ceiling and the side wall . The smallest possible distance between the filling opening and the plane that limits the overall height is determined by the outer diameter of the filling line, which is immediately after the line elbow. flows into the filling chamber. For manufacturing reasons, it may be favorable in the case of the container, which is made in particular from blanks of textile material, to arrange the ventilation opening in the side wall in the region of the upper edge, with a connected ventilation line also forming a straight tube. If the ventilation opening is arranged in the container ceiling near the upper edge, the filling line can be known. Be fed way above the tank ceiling. If the ventilation opening is provided in the side wall next to the upper edge, the filling line is also fed through the side wall directly below the tank ceiling without loss of useful height. Since the container ceiling can in this case lie directly on the upper room delimitation plane, the distance between the filling opening and the room delimitation plane essentially also only depends on the diameter of the filling line.

Another measure to increase the capacity of the container, which is also effective regardless of the rising course of the filter cover, is that the cross-sectional area of the filling opening is larger than the cross-sectional area of the filling line. The filling line can have a filling opening that is larger than its cross section. It can also be branched in the central area and have a filling opening in each branch. In any case, the upper bulk cone of the material to be conveyed in the container is converted into an approximate truncated cone, the top surface delimitation line of which is formed by an encircling line of all filling openings.

However, the capacity can also be increased by taking measures in the lower part of the container, whereby the combination of all measures naturally has the greatest possible effect. The height of a discharge device attached to the outlet connector of the container should also be as low as possible so as not to impair the usable height. Vibratory conveyor troughs are particularly suitable for this purpose, and their inflow opening can generally be smaller than the cross section of the outlet connection. A taper must therefore be provided between these two. In a further embodiment, this is designed as a funnel insert for the outlet connecting piece, the one side wall of the funnel-shaped outlet extending into a funnel neck funnel bottom and a ring fleece surrounding this, which extends downward from the upper edge of the funnel bottom and is braced with the outlet neck of the container. As a result, the funnel nozzle of the funnel insert is essentially at the same height as the outlet nozzle itself or only slightly lower. The funnel insert is preferably inserted into the outlet nozzle from above, in a preferred embodiment the funnel bottom extending over the ring flange parallel to the adjoining area of the side wall of the Spout protruding, annular support projection.

When using a vibratory conveyor as a discharge device, at least the funnel-shaped outlet of the container also vibrates. This enables yet another measure to increase the usable space of the container. This consists in that the inclination of the side wall, at least in the area adjoining the outlet connection, is less than the natural slope angle of the free-flowing material. The vibration drive also discharges the material lying there within the natural slope angle. In the area adjoining the outlet nozzle, the side walls can be cut parabolically, as a result of which the usable space is increased again, the amount of curvature decreasing towards the outlet nozzle.

In a preferred embodiment of the vibration discharge device, it comprises a vibrating conveyor trough which is closed at the top and which can be attached to the outlet nozzle of the container essentially perpendicular to the nozzle axis, and in which a dividing wall which keeps the vibrating conveyor height smaller than the trough height extends downward from the cover plate of the vibratory conveyor trough.

A further saving in height can be achieved by that the funnel neck is provided with an external thread which can be screwed into an annular web with an internal thread inserted into the cover plate. The ring web protruding into the vibrating conveyor trough can at the same time form the partition which limits the height of the vibrating conveyor, since the height of the ring web cannot fall below a certain dimension when the funnel nozzle is screwed in.

For use in pneumatic suction conveyor systems, for example in the supply of stationary heating systems with granular coal, it is provided in a preferred embodiment that

a connecting piece of a suction line leads laterally away from the space of the closed vibrating conveyor trough that remains outside the natural cone of material emerging through the outlet piece of the container, the projection of the partition wall in the longitudinal direction of the channel onto the connecting piece of the suction line partially, preferably about a third, covering its mouth cross section.

As a result, a short-path vibratory feed stage is placed in front of the actual suction feed. The vibration conveyor takes the material to be conveyed directly from the container, whereby the formation of bridges in the container outlet is also prevented by the vibration and moves it at least until the material to be taken over by the suction conveyor system loosely and without exposure to the material contained in the container in the vibrating conveyor trough Available. This means that practically only that portion of the free-flowing material is absorbed by the suction conveyor system that lies outside the cone of material extending from the container outlet into the trough. Due to the partition wall, which limits the Schingförderhöhe, an upper part of the cross-section of the mouth of the suction line is kept free, in the lower part of the vibration-promoted Good has occurred. This means that at the beginning of each suction phase of the suction conveyor air can freely enter the suction line, which initiates the entrainment of the material to be conveyed. Likewise, at the end of each conveying phase, after the vibratory conveyor, for example an unbalance motor, has been switched off, the suction line can be sucked completely empty, since the air required can enter the free mouth cross section above the vibratory conveyor height. This will, of course, continue to extract material to be conveyed from the space remaining outside the natural pouring cone and therefore also at least partially empty it; however, since the vibration delivery is interrupted, the bulk cone material, which is indeed loaded by the container goods, is not conveyed further, nor is it fed into the suction conveyor, so that the suction line is completely emptied after a relatively short time, and then the suction phase is also ended. The conveying air is sucked in to support the discharge from the container through the closed vibrating conveyor trough, since sufficient air channels remain between the free-flowing material.

In practical long-term tests, it has been shown that the occurrence of malfunctions can be prevented in particular if the distance between the partition and the mouth of the connecting piece of the suction line corresponds to approximately twice the gutter height.

In a further embodiment, it is provided that the connecting piece of the suction line is arranged on a lateral, detachably fastened end plate of the vibrating conveyor trough. After removal of the end plate, the entire length of the vibrating conveyor trough is accessible.

In a further embodiment of the invention it is provided that between the mouth of the outlet port of the container and the connecting piece of the suction line, the partition extends approximately in a tangential plane of the bottom surface of the natural pouring cone. According to this embodiment, a separate partition is thus designed to limit the height of the material to be conveyed, the arrangement in the tangential plane having proven particularly advantageous to the experiments. It has also proven to be advantageous if the partition extends approximately over the upper half of the channel height and the upper edge of the mouth cross section of the connecting piece is approximately two thirds of the channel height.

The connecting piece of the suction line is preferably represented by a straight piece of pipe which extends through the end plate at approximately 45 ° and which is cut on the inside parallel to the end plate. Such a design has the advantage that the partition provided as an additional component does not have to be attached to the vibrating conveyor trough in the above-mentioned tangential plane. The attachment of the partition can also be achieved in that at least one arm extends from the part of the connecting piece protruding into the inside of the vibrating conveyor trough parallel to the trough bottom, at the free end of which the partition is attached, so that even in this case after removing the end plate entire vibratory conveyor trough is freely accessible. When using the device in coal conveying systems, it also proves to be advantageous if an opening is arranged in the surrounding area of the channel bottom on the connection piece side. As is well known, coal has a tendency to release contained water that drips from the container into the vibrating conveyor trough. The container connection is outside the channel center of gravity, so that when using containers made of textile material, the weight of the channel results in a slight slope of the channel bottom. The water therefore flows to the deepest area of the channel, in which the bottom opening is formed, through which it can exit the device. It works when the suction conveyor is operating the bottom opening, which is smaller than the grain size of the material to be conveyed, is not disadvantageous, since small amounts of external air enter through it, so that the conceivable escape of dust components is prevented. The small amounts of external air also make it easier to start each suction phase and empty the suction line at the end of the suction phase. In order on the one hand to empty the container in a different way than through the suction line and on the other hand to supply larger amounts of external air if necessary. can, it is provided in a further embodiment that in the cover plate of the vibrating conveyor trough in the area between the connecting points of the suction line and the partition there is an opening closed by a removable leg, a lockable pipe socket rising from the cover.

The invention will now be described in more detail below with reference to the figures in the accompanying drawings, without being limited thereto.

1 and 2 show two vertical sections through two exemplary embodiments of the ice, FIG. 3 shows a vertical section through a discharge device according to line III-III of FIG. 4, FIG. 4 shows a section along line IV-IV of FIG. 3, and FIG. 5 shows a vertical section according to FIG. 3 through a further embodiment.

Figures 1 and 2 show two versions of the container with the same usable space, a container according to the prior art being shown in dotted lines in both. The additional filling volume that can be achieved when all measures are used together is shown hatched and designated by the number 26. It ranges between 20% and 40% of the original Lichen volume, the available room height h between the floor 24 and the ceiling 25 is unchanged. The container 1 made of flexible, airtight material of cylindrical or prismatic basic shape is suspended from a support frame, not shown. The lower

Part of the container 1 represents a funnel-shaped outlet 6 which merges into an outlet nozzle 7. The side wall 21 of the funnel-like outlet is not cut following the natural slope line 13 of the granular, free-flowing material, but rather has a substantially lower inclination, at least in the area surrounding the outlet connection 7. In vertical section, the section curve of the side wall 21 can be, for example, a parabolic load or a similar curve. It could also represent a straight line with a consistently lower slope. A vibration discharge device is attached to the outlet nozzle 7 and has, for example, a closed vibrating conveyor trough 19 acted upon by a balancing motor 20. The opening cross-section of the vibrating conveyor trough 19 is, in the interest of a low overall height, as small as necessary and therefore generally much smaller than the opening cross-section of the outlet connection 7. A tapering piece is therefore required which is designed as a funnel insert 14. This has a funnel bottom 15 with a support ring 22 that extends the outlet area 23 of the side wall 13, from which an outer ring flange 16 and a funnel neck 18 protrude concentrically, each pointing downward. The ring flange 16 is adapted to the diameter of the outlet nozzle 7, inserted into this and connected to it in any manner, for example by means of a pipe clamp, a tension band 17 or the like. The funnel neck 18 is adapted to the diameter of the inlet opening of the vibrating conveyor trough 19 and screwed into it, for example, as will be explained in more detail later. As a result, the top of the vibrating conveyor trough 19 is located directly or only slightly below the outlet connection 7, whereby at least the height of the ring flange 16 is saved. (The upper edge of the outlet nozzle 7 'when using conventional tapering pieces is shown in dotted lines.)

On the top of the container 1, on which the arrangement of the filling line 9 ', the container ceiling 4' and the filter ceiling 5 'of a conventional container suitable for the same room height h is also dotted, according to the embodiment according to the invention, the conveying air is of conveyed material separating filter cover 5 arranged obliquely rising to the center. It therefore has a smaller distance from the container ceiling 4 in the area of the filling line 8 and a greater distance in the area of the side wall 3 of the container 1. The vent 12 is relocated to the area of the upper edge 10 of the container 1, in which it is at the greatest distance from the filter cover 5, so that it cannot move or close the inlet opening 12 even when inflated during the pneumatic filling of the container.

In FIG. 1, the filling line 8 is fed horizontally between the container ceiling 4 and the room ceiling 25, as in the prior art, and the ventilation opening 12 is provided in the container ceiling 4, from which the ventilation line continues at an angle. The arrangement of the vent opening 12 in the edge area and the rising arrangement of the filter cover 5 allows it to be connected to the container cover 4 in the central region, in which the filling line 8 has an angled, only extremely short vertical extension, which forms the filling opening 9, through the container cover 4 opens directly into the filling space 2 of the container 1. According to FIG. 2, the container ceiling 4 is provided above the filling 8, ie the side wall 3 of the container is pulled up to the ceiling 25, so that the filling line 8 and the ventilation opening 12 are indeed are provided in the same spatial arrangement, but lead through the side wall 3 into the air space 11. The arrangement of the filter cover 5 is unchanged from the embodiment according to FIG. 1, since it is also again assigned to the filling opening 9 in the center, and in this case is fixed to the filling line 8. The distance between the ceiling 25 and the filling opening 9 is composed in both versions of the outer diameter of the filling line 8 and the negligible, exaggerated thickness of the container ceiling 4. The cross-sectional area of the filling opening 9 is in both

Versions compared to the cross-sectional area of the filling line 8 significantly enlarged. For this purpose, the elbow shown in the drawings can be provided with the vertical leg forming only the opening edge of the filling opening, which in the embodiment according to FIG. 2 also serves for the central fastening of the filter cover 5. In the embodiment according to FIG. 1, in which the filter cover 5 is connected to the container cover 4, the filling line 8 can also be divided into several radial branches, each of which has a filling opening, so that this has the diameter of the filling opening 9 shown cover the corresponding area. When the container is filled, the upper truncated cone shown is thereby achieved, which contributes significantly to increasing the useful diameter of the container. The diameter of the filling opening 9 and thus the top surface of the truncated cone can also be chosen to be larger than shown, the maximum being essentially achieved when the slope of the filter cover 5 corresponds to the natural angle of repose of the material or, if this is larger, at approx. 45 °.

By combining the described measures, an increase in the capacity of a square container 1 with a base area of 2 × 2 meters in a room with a height of 2.20 m could be increased from 3 tons of coal granules to 3.8 tons of coal granules on the container lower part about 40% and that on the upper part of the container about 60% of the useful volume increase. It is clear that each of the measures described individually applied leads to an increase in the usable container volume.

3 to 5 show two versions of a vibration support device for use in pneumatic suction conveyor signals.

To generate the conveyor vibrations, the balancing motor 20 is arranged on an end plate 32 of the vibrating conveyor trough 19, which is shown at approximately 30 ° to the vertical. In a circular opening of the cover plate 33 of the vibrating conveyor trough 19, an inwardly projecting ring web 42 with an internal thread is inserted, into which the funnel neck 18 is screwed. The vibrating conveyor trough 19 extends perpendicular to the axis 48 of the funnel nozzle 18 and comprises a bulk space 46, which is filled by the pouring cone of the material to be discharged flowing in from the container 1, and a subsequent suction space. Due to the vibration of the vibrating conveyor trough 19, the material flowing out of the container 1 is conveyed in the longitudinal direction of the trough into the suction space into which a connection support 36 of a suction line 35 of a suction conveyor system opens. The connecting piece 36, which is preferably arranged in the second, in particular removable, end plate 34, is set so that the cross-sectional area of its opening is partially covered in the conveying direction by the projection of the partition wall 37 projecting into the vibrating conveyor trough 19 from above. The partition 37 limits the delivery head a of the - moving material, so that the suction chamber is divided into a lower delivery chamber 44 and an upper air space 45. The surface 29 of the material set in motion therefore extends into the connecting piece 36, the upper part of the cross-sectional area of the mouth of the connecting piece 35 remaining free to the extent of the height b. An opening 39 is provided in the channel bottom 43 in the area of the connecting piece 36. Furthermore, the air space 45 is removable Lid 40 accessible in the cover plate 33, in which a further lockable pipe socket 41 is arranged, which opens into the air space 45.

In the embodiment according to FIGS. 3 and 4, the partition 37 is formed by a separate component which is fastened by two arms 38 to the end of the connecting piece 36 which projects into the vibrating conveyor trough 19. When the end plate 34 is removed after the closure devices 30 have been loosened (FIG. 4), the partition 37 is also removed from the vibrating conveyor trough 19 so that it is freely accessible over the entire length and the entire height c. The partition 37 is preferably at a distance from the end of the connecting piece 36 which corresponds approximately to twice the channel height c. It is furthermore preferably arranged in a tangential plane 31 on the bottom surface of the natural pouring cone formed by the material flowing in through the funnel mouth 27 when the unbalance motor 20 is switched off, this arrangement having proven particularly advantageous in tests.

in the embodiment according to FIG. 5, the partition 37 is formed by that part of the ring web 42 which faces the connecting piece 36 of the suction line 35. The ring web 42, into which the funnel connection 18 is screwed, projects to the extent of the partial height b into the vibrating conveyor trough 19, so that the material conveyed by the vibration in turn assumes the delivery height a in the delivery space 44, so that the air space 45 remains above the height b. In this embodiment, too, the connecting piece 36, which in particular rises above 45 °, is arranged such that the projection of the partition 37 onto the connecting piece 36 covers the upper part, preferably the upper third, of the cross-sectional area of the mouth. The surface 29 of the moving goods therefore runs at a distance b from the uppermost point of the opening edge of the connecting piece 36. The function of the discharge device is now as follows: the pourable, granular material filled in the container 1 forms a natural pouring cone in the bulk space 46 of the vibrating conveyor trough 19, which is indicated by the dashed slope line 47. To carry out the

Good is switched on the suction conveyor system, so that the air is sucked in the direction of arrows A, mostly through the material to be conveyed, but also through the opening 39 in the channel bottom 43. Now the vibrating conveyor trough 19 is put into operation, whereby the material lying in the bulk space 46 is conveyed in the direction of the suction nozzle 36. The partition 37 limits the delivery height to the amount a, so that in both versions the air space 45 remains at least with the height b. The conveyed material entering the connecting piece 36 of the suction line 35 is grasped by the suction and transported away. This takes place with a constant excess of air, since the air can constantly enter the suction line 35 unhindered through the upper part of the cross-sectional area of the mouth. The opening edge of the connecting piece 36 is designed so that as little turbulence as possible arises, for example, bevelled, rounded, etc.

At the end of the delivery phase, the vibration drive, ie the balancing motor 20, is switched off while the suction conveyor system is still in operation. The material now contained in the conveying space 44, which is now stationary, is sucked off until a natural pouring cone in the vibrating conveyor trough 19 is reached, which is indicated by the slope line 47 emanating from the lower edge of the partition 37. The slope line 47 extends according to FIG. 3 from the additional partition 37, according to FIG. 5 from the ring web 42 downwards. The material contained in the bulk space 46, which is weighted by the material filled in the container 1, is no longer detected by the suction conveyor system when the delivery space 44 is emptied. After emptying the suction line 35, the suction conveyor system is also switched off. At the beginning of the next conveying phase, therefore, goods that get back into the conveying space 35 by vibration can be detected by the suction conveying system with a constant excess of air. The one provided in the cover 40

Connection piece 41 is used in particular for emergency air supply A 'when emptying the suction line in the event that only insufficient amounts of air can take the usual route in the direction of arrows A due to moisture, contamination of the goods in the container 1. Via the opening of the cover plate 33 closed by the cover 40, another emptying of the container 1 is also possible. When the suction conveyor system is at a standstill, the opening 39 in the channel bottom 43 also serves for the outflow of water, which is emitted in small amounts from the material contained in the container 1, in particular granulated coal. Due to the eccentric arrangement of the vibrating conveyor trough 19 with respect to the axis 48, there is a slight slope in the vibrating conveyor trough 19, so that water drops emerge from the opening 39. An escape of dry

Dust is not possible since air enters through opening 39 when the suction conveyor system is in operation.
