Description

The invention relates to a device for filling powdered debris in a container made of deformable material - in particular in a bag - which is arranged in a container made of rigid material and temporarily set a glove box containing a lock system, according to the preamble of claim 1. In addition The invention encompasses a method that can be carried out with this device.

There are various known systems with which you can empty toxic powder low in contamination from equipped with plastic bags barrels. One of the most common methods is the use of insulation systems. The keg is introduced through a lock into the isolator, lifted with a mechanical device, whereupon the plastic bag filled with the product is opened by an operator with gloves. The product is then manually emptied into a funnel attached to the lower part of the isolator. The disadvantage of these isolation systems is that they are designed for specific applications and therefore have very little flexibility. The space requirements and the investment costs of such systems are significant. In addition, dust build-up within the insulator is significant, so the filters clog quickly, the equipment must be cleaned frequently and there is a risk of product loss.

There is also a system that includes a clear cylindrical so-called glove box with side openings for gloves. A stainless steel ring with a flat seal is attached to the lower part of the glove box and ensures the seal to the barrel. From above, a movable Suction lance is introduced, which is connected by a sealing sleeve with the glove box. The system is connected to a pneumatic lifting device which allows the lifting and lowering of the glove box above the drum. The barrel emptying is carried out by an operator using the suction lance, which is connected to a pneumatic conveyor system. The powder is conveyed under vacuum and emptied in a completely closed manner into the container to be filled.

Compared to a conventional isolator, the advantages of such a system are a small footprint and a low investment. Depending on the type of product, however, handling the suction lance can be tedious and time-consuming. In addition, it is sometimes difficult to empty the plastic bag completely. In addition, the system can not be used for lumpy products. When emptying a large number of barrels (> 10 barrels), the emptying time for a production unit may be very long and inadequate (10 - 15 min / barrel).

In view of these circumstances, the inventor has set the goal of eliminating the identified problems. In particular, barrels equipped with plastic bags containing toxic powders should be able to be emptied practically free of contamination (<1 μg / m ³ ) and semiautomatically.

To achieve this object, the teaching of the independent claim; the dependent claims indicate favorable developments. In addition, all combinations of at least two of the features disclosed in the description, the drawings and / or the claims fall within the scope of the invention. For the given design ranges, values within the specified limits should also be disclosed as limit values and used as desired.

According to the invention supports - preferably at least two laterally spaced from one another, forming a main frame side frames - at a distance to a shelf a rotatable shaft on which at least one designed as a glove box hood - or a hood trough or a hood system - is fixed. At variable-length piston / cylinder units is also mounted at a variable distance from the shaft at least one parallel to the shaft longitudinal axis support plate as a holding base for the rigid container; this is at the other end of a tightly connectable in the hood, the hood trough and the hood system protruding connecting pipe.

According to a further feature of the invention, the hood or the hood trough - or the outer region of the hood system - of metallic material, preferably made of stainless steel, shaped and provided at least in the bottom part with a window element; At a front area in breakthroughs gloves or glove-like devices are provided, in which an operator can intervene to open inner bags of the drums or containers contamination-free.

As low it has proven to connect the rigid container or barrel by laterally mounted pneumatic piston with the hood or the hood trough or the hood system. These pistons seal the system by forcing the keg against the gasketed adjacent lower plate of the device.

According to another feature of the invention, the hood or the hood trough or the hood system is mounted in a receiving box of the shaft from which protrude the mentioned piston / cylinder units for the support plate.

This system is installed on a so-called main frame, which offers a pair of shaft bearings on side frames for the shaft and these shaft bearings near - about radial - end walls of the receiving box, protrude from each of which axially parallel longitudinal walls; two mutually aligned longitudinal walls are formed as connection elements for the piston / cylinder units.

It has proved to be favorable to fix the hood or the hood trough on the longitudinal walls of the receiving box remote from the piston / cylinder units. In addition, the hood or the hood trough should span at least one axis-parallel plate, which is penetrated by the connecting pipe.

According to a further feature of the invention, the connecting tube is associated with a clamping frame with which a pressing pressure can be generated on the outer surface of the pipe wall, thanks to which the free end of the bag can be fixed to the connecting pipe. For this purpose, a pressure ring of the clamping frame to be applied to the pipe wall, which is designed to be displaceable radially and / or axially parallel; This pressure ring is preferably offered as a flexible and inflatable profile. The pressure ring is advantageously held by at least one thrust leg leading him, which surrounds an axially parallel clamping arm of the clamping frame and is axially slidable on this and set at a position to be selected.

Advantageously, between the clamping frame and connecting tube of the mouth region of the container made of deformable material - ie the bag - are set. The latter is to be arranged to receive the powdery aggregate as an inner bag in an outer bag surrounding it as a shell; Both bags are located in the mentioned rigid container, so the barrel of the device. The mouth region of the envelope or outer bag is preferably attached to a one - associated with the rigid container or barrel - Breakthrough of the hood or the hood trough or hood system surrounding ring-like fastening device set. This is a breakthrough circumferential profile ring whose outer surface is assigned at least one pressure profile as a clamping element for the mouth region of the outer bag. The profile ring should be integrally formed on the outside a footbridge as a support for a pressure profile.

According to the invention, the connecting tube is connected by means of a connecting element to a pneumatic conveying system, the connecting element preferably tapering away from the connecting tube in a funnel-like manner. In addition, the connecting element should be equipped with an optionally existing jamming or clumping in the powdery debris breaking device, such as a grinder.

Of particular importance is that the device is equipped with a manual or automatic tilting device, with which the system can be tilted by 180 °. Depending on the application, the upper part of the system may be equipped with different connections. In any case, the system consists of a connecting tube with an inflatable seal to which the inner bag is to be attached.

In order to avoid that the inner bag falls down when tilting the barrel and thus hinders a complete emptying of the barrel, certain processes must be considered when attaching the bag. The previously opened inner bag is first attached by means of an O-ring to a welded on the bag holder ring. The top of the bag is then attached to the connecting tube, which is installed at the top of the system with an inflatable seal. Since the space between the bag and the barrel is closed, the bag is normally held back during emptying. It is also possible this room under slight negative pressure to ensure the secure hold of the bag.

In one embodiment of the invention, a rotatable with this process apparatus is arranged on the shaft, extending from the radially to the shaft, the connecting pipe; a latter holding box half of the process apparatus is associated with the receiving box of the device, the other box half provided with a closable filling element. For this purpose, at least one away from the shaft cross-sectionally tapering box half is particularly favorable; between the to the connecting tube tapered box half and the connecting pipe to be arranged a closure member.

On the box halves on both sides in each case a common sleeve surrounding the shaft to which a radial panel element is fixed for connection to the receiving box. In particular, to the shaft of this device, a motor is connected.

In the context of the invention is also a connection funnel, which is connected by a hose with a pneumatic conveying system and mounted in the upper part of the hood on the connecting pipe. After the keg has been connected to the system, it is tilted and automatically emptied by the conveyor system. For heavy flowing products, a float may be used to break possible powder bridges. Advantageously, the lower plate of the hood can be made of a porous material to replace the filter of the suction funnel.

In the context of the invention is a method for filling powdered debris in a container made of deformable material in which the heap receiving bag is inserted into another bag and placed with this in the rigid container, after which the rigid container formed as a glove box hood or a hood trough or a hood system tightly connected and the mouth region of the opened inner bag is connected to a connecting tube. The debris is fed to a reactor or dosed to another inner bag.

The system according to the invention can therefore be used, for example, rotating process apparatuses - biconical dryers, mixers or the like. - to fill in a closed way and empty. The hood is permanently connected to the process apparatus. A barrel filled with raw material is added to the system and loaded by gravity into the apparatus after it has been tilted 180 °. At the end of the process, which involves drying and mixing, the powder is loaded into a new drum.

The system according to the invention may also be used as a dispensing unit; In the pharmaceutical industry, it is often customary to fill a drum with raw material into smaller, precise loads.

It is also possible to dose a precise amount of powder from one barrel to a second barrel by placing two hood systems, separated by a metering valve, on scales.

The barrel or the container 10 is by pneumatic pistons, attached to the side of the system are connected to the hood 22. These pistons seal the system by pressing the barrel 10 against the peripheral edge 24 of the system, as previously noted with a gasket. Above the peripheral edge 24, a waste sack 27 can be seen here, which receives the clamping surfaces 54, 48 described below after their removal. Not shown in Fig. 4 are two gloves 26, which are both mounted on the front of the hood 22 in apertures. In contrast, two filters 32 of the so-called "push-through" type are provided opposite the gloves 26 (FIG. 17).

In particular, Fig. 3, 5 it can be seen that from the peripheral edge 24, a profile ring 28 angle-like cross section of the height i protrudes downwards, the - opposite to a molded, outwardly directed footbridge 29 endender - a clamping band 30 at a radial distance a ,

The vertical tube 34 is associated with a tensioning frame 38 above its mouth edge 36, the structure of which is shown particularly clearly in FIG. 9; from a - at a central distance b to the wall 35 of the vertical tube 34 arranged on a radial rod 39 - axially parallel clamping arm 40 protrudes toward the vertical tube 34 toward a pressure profile 42, which thanks to a clamping arm 40 surrounding push foot 43 to the former - by pressing a Handle 41 can be moved axially parallel and with a pressure ring 44 of elastic material as - if necessary inflatable - sealing member against the vertical tube 34 is able to be performed.

In the interior 20 of the barrel or container 10, a arranged around the vertical axis A bag 46 is indicated, the upper mouth portion 47 is connected in the open state of Fig. 2, 4, 6 to 12 to those profile ring 28 of the hood 22 by a round profile 31 and the interior 48 receives an inner bag 50 for powdery products Q. The hood 22 is shown in FIG. 1, 2 at a distance from Upper edge 19 of the container 10, a limited by the clamping frame 28 hood opening 23 is closed by a clamping surface 54, which in turn is pressed according to FIG. 3 with an O-ring or round profile 31 to the outer surface of the profile ring 28. This clamping surface 54 may be formed, for example, by a portion of the mouth region 47 of the previously treated - and then cut - outer hull bag 46 and braced with a central bracket 56.

Thanks to the two attached to the hood front gloves 26, the inner bag 50 can be opened safely in the closed barrel or container 10 from the outside by an operator and his mouth 51 are fed to the pressure ring 44. According to Fig. 6 to 10 of the mouth portion 51 of the inner bag 50 is pressed after lifting the push foot 43 on the clamping arm 40 in the arrow direction x by the aforementioned pressure ring 44 to the outer surface of the wall 35 of the vertical tube 34 and this connected to the bag space 52. If the latter is filled by introducing the pulverulent product Q, its mouth region 51 is separated off and braced in accordance with FIG. 10 by a clamp 56; he then serves as a clamping surface 58 for closing the vertical tube 34. Another clip 56 _a closes the remaining inner bag 50. The latter is pressed into the container interior 20. In Fig. 14, the mentioned flat profile or strap 30 can be seen, which is released to move the O-ring 31 down.

Thanks to a sketched in Fig. 16, 18 rotating device 60 as a main frame of the inner bag 50 is emptied quickly in a simple manner. This rotating device 60 has at a clear distance e from each other on two side frames 62 which are fixed on a shelf B and are each provided with a shaft bearing 63, between which on a shaft 64, the longitudinal axis N at a distance n to the control shelf B, a rotatable receiving box 66 is located; this has at two radial end walls 67 each two parallel waves Longitudinal walls 68 and includes a hood trough 80, in Fig. 16 from above the connecting tube 34 _a engages. In the box-like hood trough 80 is at achsprelleen shoulders 81 of the side wall 82 a parallel to the longitudinal axis N of the shaft 64 transverse plate 84 defined by window glass and penetrated by the connecting pipe 34 _a . The latter is surrounded by a uniform with the glass or transverse plate 84 and iw above described tensioning frame 38 _a . From the axis-parallel clamping arm 40 _a projects at the free end at right angles from a transverse arm 45, in the groove-like pressure profile 42 of the pressure ring 44 stores and in Fig. 18 the mouth portion 51 of the inner bag 50 presses against the tube wall 35. This inner bag 50 passes through the - located here in a two ridge profiles 86 of the hood trough 80 parallel bottom plate 87 located hood breakthrough 23, the profile ring 28 surrounds. On the foot land 29 of the mouth region 47 of the outer bag 46 is attached. Above the bolted to the side wall 82 bottom plate 87 of the profile ring 28 is continued by an attachment ring 85 _, which offers on its outer periphery clamping elements 85 _a for the inner bag 50.

The connecting pipe 34 _a opens at the other end into a connecting funnel 70, from which a connecting pipe 71 with locking mechanism and filter 72 protrudes radially. On the connecting funnel 70, which is connected by a hose to a pneumatic conveying system, a filter is installed, which allows to suck the conveying air of the powder. Optionally, a lid 75 of the funnel 70 may be formed as a porous material plate to replace the filter of the suction funnel.

Of the bottom longitudinal radial walls 67 of the receiving box 66 in FIG. 16, axially parallel piston / cylinder units 76 protrude, which are connected at the other end to a support plate 78, the light wave spacing n _{1 of which is} variable. This support plate 78 is seated in the starting position with adjustable feet 79 to the aforementioned shelf B. Its sacks 46, 50 are connected in the manner described above with the hood trough 22 _a , so that the bag space 52 connects to the connecting pipe 34 _a . In the cross section of Fig. 17, 33 indicates a filter for the powder; the latter is - not recognizable in the drawing connected to the upper part of the connecting hopper 70.

The previously opened inner bag 50 is first attached by means of the round profile or O-ring 31 to a welded to the bag holder ring. The upper part of the inner bag 50 is then fixed to the vertical or connecting pipe 34 _a , which is installed in the ridge region of the system with an inflatable seal. By operating the piston / cylinder units 76 and their shortening, the space between the inner bag 50 and the barrel 10 is closed for emptying. It is also possible to put this space under slight negative pressure to ensure the secure hold of the inner bag 50.

After rotating the shaft 64 by 180 ° by actuation of a handwheel 65 with the shaft 64 downstream drive member 65 _a , the connecting pipe 71 of the connecting hopper 70 is connected to a delivery hose 88 to a reactor unit 90 and that to a lateral attachment piece 96 of a reactor 92 towering cylinder tube 94 made of electrolytically polished stainless steel, the interior 95 serves as a pumping chamber; this is connected to the delivery hose 88 serving as the supply line - conveying direction y. That neck nozzle contains a so-called butterfly valve 89 as a blocking member in a connection flange for the delivery hose 88.

Above the lid 93 of the reactor 92, a valve housing 98 and a drive element 99 for a butterfly valve are indicated. Towards the top, the cylinder tube 94 terminates on a filter insert 100, the one - axial with a T-shaped connecting pipe 102 provided - Domdeckel 104 is spanned. This is determined by a locking device on the tow hook of the cylinder tube 94. From the connecting pipe 102, on the one hand, there is a vacuum line 106 with a vacuum valve 107 for a vacuum pump located upstream of it, and on the other hand a conveying gas line 108 containing a check valve 109 for a conveying gas source.

During a suction phase, the butterfly valve 89 of the supply line 88 opens, the discharge line remains closed. Now, the pumping chamber 95 fills thanks to the construction of a vacuum on the vacuum line 106 to a desired level, possibly even completely.

After a predetermined period of time, the supply line 88 is closed and the discharge line is opened. The powder Q is discharged by means of pressure - for example, nitrogen for filter cleaning - after opening the check valve 109 in the conveying gas line 108. At the end of the suction phase, the vacuum line 106 remains open for a certain time before the butterfly valve of the discharge line is opened to remove the oxygen from the pumping chamber 95.

Of particular importance in this process is the filter in the filter cartridge 100, which retains the powder while maintaining the suction capacity of the system. Thanks to its location between pumping chamber 95 and source of conveying gas, the filter is cleaned every cycle and therefore maintains its full filtration capacity.

The blocking elements 89, 107, 109 and the butterfly valve of the discharge line are connected to each other at a control box tax technically. During a suction phase, the butterfly valve 89 of the supply line 88 opens, whereas the discharge line remains closed. Thanks to the thereby open vacuum valve 107, the pumping chamber 95 sucks fully; closes after a predetermined period of time the supply line 88 and the discharge line is released. The conveyed material is ejected by pressure - compressed air or nitrogen for filter cleaning. The filter in the upper part of the cylinder tube 94 retains the finest particles and cleans itself with each evacuation cycle.

Before the introduction of the powder into the downstream reactor 92, air and powder are separated from each other by delaying the closing of the vacuum shut-off valve 107 from opening the Förderguteinlaufes. So that when releasing the discharge line no gases of the reactor 92 are sucked in, the cylinder tube 94 is first pressurized and only then opened the drain valve. Moreover, the vacuum line 106 can only be opened when the discharge line is closed.

The attached to the hood trough 80 and tilted barrel 10 is automatically emptied by the conveyor system. For heavy flowing products, a reciprocating motion can be used to break possible powder bridges.

When the product Q to be evacuated contains lumps, a lump breaker system indicated at 74 in FIG. 20 may be integrated into the suction or connection hopper 70. In this embodiment, the side walls 82 _a rectangular cross section and - like the side walls 82 of Fig. 16, 19 - connected to the longitudinal walls 68 and the ridge plate 86 by screws 69.

The system according to the invention can also be used to, for example, rotating process apparatuses 110 - biconical dryers, mixers or the like. - to fill in a closed way and empty. In Fig. 21, the hood system 80 _a lying in the vertical axis A of the device 61 is permanently connected to the process apparatus 110 and is loaded by gravity into the device 61 after it has been tilted by 180 °. Dry at the end of the process, mix - the powder is in a new barrel 10 loaded. The shaft 64 of the device 110, having an overall height f of, for example, 2200 mm and a length g of about 2500 mm, is driven by a motor M mounted outside the side frames 62; between the latter, the shaft 64 passes through the process apparatus 110, which contains two box halves 112, 112 _t , each tapering away from the shaft 64, on both sides of which the bushes 113 surrounding the shaft 64 connect. At the latter, in each case a radial panel member 114 is set for a receiving box 66 _a , with which the hood system 80 _{a is} connected.

The upper box part 112 has a closable filler neck 111. The connecting pipe in the vertical axis A 34 _a and also passes through here, a clamping frame 38 - of the lower casing part 112 _t is the interposition of a closure 116th

The system according to the invention can also be used as a dispensing unit. In the pharmaceutical industry, it is often customary to fill a drum with raw material into smaller, precise loads. With the device 120 of FIG. 23, it is possible to meter a precise amount of powder Q from a barrel 10 into a second barrel 10 _a by two axially spaced q - hood systems 80 _b - by a metering valve 122 are separated - connects with scales. These - both hood systems 80 _b assigned - Wege organs are designated in Fig. 23 with 124.

Finally, FIG. 37 shows the FIG Closing the drum 10 containing the metered amount of powder.

In Fig. 38, 39 it is clarified that with a system 128 according to the invention not only barrels 10 can be emptied, but also a so-called big bag 130 with a glued-in double liner. Here is a bottom open hopper 70 _{a arranged} in a driving wheels 132 movable support frame 134. From the hopper 70 _a is a connecting pipe 71 _a for a feed line 88, which leads, for example, to the reactor 92 of FIG. At the upper hopper edge 73 sets a filter 136 for the promotion.
