Definitions
- the invention relates to a transport container for volatile powders.
- Volatile powders are used in the composition of many composite materials. It is for example possible to embed such powders in a resin matrix. For example, to lighten certain resins, it is possible to include a charge of microballoons formed of hollow spheres a few micrometers in diameter. Such filled resins are used in particular for their particular acoustic properties. The presence of a vacuum inside each sphere tends to lighten them, making the powders formed from microballoons very volatile before their inclusion in the resin.
- the invention relates to the transport container.
- Handling the powder inside the glove box consists, for example, of filling a transport container with a precise quantity of powder.
- the evaluation of the quantity of powder can be done by weighing in the glove box.
- the transport container is sealed in the glove box and then extracted from it.
- the container is then transported to a place of use, for example to insert the powder into a reactor allowing mixing with a resin.
- the insertion in the reactor poses a problem of complete emptying of the transport container.
- the emptying can be done by opening the seal of the transport container then emptying the dose of powder. This must be done in compliance with the regulations, therefore in a confined and possibly oxygen-depleted enclosure. These operations are cumbersome and costly.
- the invention provides a much simpler solution for transporting and extracting the powder from its transport container while ensuring complete emptying of the container.
- the subject of the invention is a transport container for volatile powders comprising a hermetic enclosure of tubular shape with a circular section around an axis, a suction duct configured to collect the volatile powder disposed in the hermetic enclosure, the suction duct opening into the hermetic enclosure by means of a rod movable in rotation around the axis and movable in translation along the axis, the rod comprising a first tube s extending along the axis and a second tube extending radially with respect to the axis, the first tube and the second tube each comprising an internal channel communicating with the suction duct, the second tube having at least one opening s opening in the hermetic enclosure and communicating with its internal channel, the opening making it possible to collect the powder located in the hermetic enclosure.
- the first tube passes through a cover closing the hermetic enclosure perpendicular to the axis through a stuffing box, the internal channel of the first tube communicating only with the suction duct and with the inner channel of the second tube.
- the second tube extends symmetrically on either side of the axis.
- the second tube advantageously has several openings opening into the sealed enclosure and communicating with its internal channel, the openings being arranged asymmetrically on either side of the axis.
- the openings are advantageously arranged along the second tube so as to cover a circular section of the hermetic enclosure during rotation of the rod around the axis.
- the second tube is advantageously provided with plastic caps each arranged at one end of the second tube.
- the plugs can each comprise an opening contributing to the removal of the powder.
- the hermetic enclosure may comprise a cover extending mainly perpendicular to the axis, the cover comprising an opening centered around the axis, the opening comprising a bearing allowing guidance in rotation around the axis and in translation along the axis of the first tube in the opening and sealing means arranged between the opening and the first tube.
- the cover advantageously comprises a porthole allowing an operator to observe the interior of the hermetic enclosure.
- the lid may mainly comprise a transparent glass plate.
- Figure 1 schematically shows an example of an enclosure allowing the filling of a transport container according to the invention
- FIG 2a shows in more detail the transport container shown in Figure 1;
- Figure 2b shows in section the transport container of Figure 2a
- Figure 3a shows a suction rod allowing the extraction of the powder from the transport container of Figure 2a;
- Figure 3b shows in more detail a tube of the suction rod shown in Figure 3a
- Figure 3c shows in partial section one end of the tube of Figure 3b.
- FIG. 1 shows a device 10 for handling volatile powders.
- the device 10 comprises a glove box 12 in which the powder is handled.
- the glove box 12 is mainly formed of a hermetic enclosure comprising orifices 14, four in the example shown, allowing an operator standing outside the glove box 12 to insert his hands inside. through waterproof gloves attached to the wall of the glove box 12.
- handling may consist of a sample being taken from an input container 16, weighing a quantity of powder 18 to place it in a transport container 20.
- the input container 16 allows to fill several transport containers 20.
- the input container 16 can come from a powder manufacturer and the transport container 20 can be used in a separate reactor from the glove box 12 and in which the powder is used by example to be embedded in a resin matrix. It is understood that the dosage of a precise quantity of powder in the glove box 12 is only one example of manipulation making it possible to fill the transport container.
- the invention relates to the transport container 20 itself regardless of how it is filled.
- the device comprises an inlet lock 22 in which the inlet container 16 is placed and an outlet lock 24 in which one or more transport containers 20 are placed.
- the inlet lock 22 communicates with the box box 12 through an opening 26 which can be closed by a hatch 28.
- the exit lock 24 communicates with the glove box 12 through an opening 30 which can be closed by a hatch 32.
- the entry lock 22 has a door 34 for inserting and extracting the entry container 16 therein.
- the outlet lock 24 has a door 36 allowing the introduction and extraction of the transport container(s) 20 .
- the entry container 16 is placed in the entry lock 22 by the door 34, the hatch 28 being closed. During this introduction, the entry container 16 is sealed in order to be able to be directly manipulated by the operator outside the glove box 12. After introduction of the entry container 16 into the entry lock 22 and closing the door 34, the operator can open the hatch 28, unseal the entry container 16 to take the powder 18 from it through the opening 26.
- the dosage of the powder 18 in a transport container 20 placed inside the glove box 12 can be done by means of a scale 38, also placed in the glove box 12. Once the metering carried out, the transport container 20 is sealed and then placed in the outlet lock 24 through the opening 30. This operation of filling a transport container 20 can be repeated several times and the operator deposits several transport containers 20 sealed in the outlet lock 24. Once the transport container or containers 20 have been filled and sealed and then deposited in the outlet lock 24, the operator can close the hatch 32 in order to extract the transport container or containers 20 from the exit lock 24 through door 36.
- the volatile powders 18 may present flammability risks. This is particularly the case when the volatile powders 18 are formed from microballoons enclosing a flammable gas. To ensure operator safety, it is possible to deplete the oxygen in the air present in the glove box 12 and therefore inside the transport container 20 before it is sealed.
- the ambient air contains around 20% oxygen and the target oxygen level to be observed in the glove box 12 is a function of the degree of flammability of the powders 22. For example, to obtain an oxygen level of the order of 8%, it is possible to use a technique called lost scanning. More precisely, a permanent flow of inert gas, such as for example nitrogen, sweeps the inside of the glove box 12. A filter allows the excess air to leave the glove box 12.
- the filter is calibrated to allow air to pass and retain the particles of powder handled in the glove box 12.
- the sweeping is schematized by a nitrogen reserve 40 able to inject nitrogen into the glove box 12 and a filter 42 arranged crossing the wall 18.
- the sweeping is configured so as to reach the entire volume of the glove box 12, the volume of the entry lock 22, as well as the volume of the exit lock 24.
- a closed loop purification system which makes it possible to limit the consumption of inert gas.
- the oxygen depletion system may have a sensor for measuring the oxygen level allowing it to regulate its operation.
- the gas pressure inside the glove box 12 can be maintained slightly higher than the atmospheric pressure prevailing in the room in which the device 10 is located.
- the overpressure then prevents the ambient air of the room from penetrating into the glove box 12 through any micro leaks or through the gloves which tend to become porous over time.
- a system for cleaning the internal volume of the glove box 12 can be provided in order to eliminate the particles of powder 22 which may be deposited in the glove box 12 outside the transport container 20 during the handling of the powder. 22.
- the device 10 may comprise a vacuum cleaner 44 provided with a filter 46 similar to the filter 42.
- the vacuum cleaner 44 can be equipped with pipes, not shown, allowing the operator to reach the entire volume of the glove box 12 and also the interior of the airlocks 22 and 24. It is also possible to provide a specific vacuum cleaner for the exit airlock 24 in order to avoid completely cleaning the internal volume of the glove box 12 when the operator wishes to access the exit lock 24 to remove one or more full transport containers 20 or to drop off one or more empty transport containers.
- the device 10 can have a specific vacuum cleaner at the entrance lock 22.
- FIGS. 2a and 2b show transport container 20 in greater detail. The following description can also apply to input container 16 which itself forms a transport container between the powder manufacturer glove box 12.
- FIG. 2a represents the transport container 20 in perspective.
- the transport container 20 comprises a hermetic enclosure 50 of tubular shape with a circular section around an axis 52.
- FIG. 2b represents the transport container in section through a plane containing the axis 52.
- the hermetic enclosure 50 comprises a tubular 54 itself, a bottom 56 and a lid 58.
- the bottom 56 and the lid 58 both close the tubular part 54.
- the bottom 56 and the lid 58 are substantially flat. They extend mainly perpendicular to axis 52.
- Bottom 56 is integral with tubular part 54.
- Cover 58 is removable.
- a flange 60 can form one end of the tubular part, the end opposite the bottom 56.
- a seal 62 is compressed between the flange 60 and the cover 58. The compression of the seal 62 is ensured by means of latches 64 being articulated on the cylindrical part 54 and coming to rest on the cover 58. Any other means of positioning and sealing the cover 58 with respect to the tubular part 54 is of course possible. It is for example possible to compress a joint by means of screws.
- the hermetic enclosure 50 comprises a suction duct 66 configured to pick up the powder disposed in the hermetic enclosure 50.
- the suction duct 66 passes through the cover 58.
- the suction duct 66 is closed off. This closure can be achieved by means of a connector 68 which remains closed as long as a pipe is not connected to it.
- the fitting of the pipe in the connector 68 makes it possible to open the connector 68. Any other sealing means, such as for example a simple plug is possible.
- the removable lid 58 facilitates the filling of the transport container 20 by opening it widely.
- the cover can be fixed, like the bottom 56, permanently and the filling of the transport container 20 can be carried out by any other means, for example by the suction conduit 66 which can be used in both directions to make it circulate the powder 18. If it is desired to retain the one-way suction duct for extracting the powder from the transport container 20, it is possible to provide another duct passing through the walls of the hermetic enclosure 50 to fill it.
- the suction duct 66 opens into the enclosure by means of a rod 70 movable in rotation around the axis 52 and movable in translation along the axis 52.
- the rod 70 comprising a first tube 72 extending along axis 52 and a second tube 74 extending radially relative to axis 52.
- Figure 3a shows an advantageous example of rod 70 outside the hermetic enclosure 50 and Figure 3b shows a tube 74 of this advantageous example.
- the rod 70 thanks to its shape and its possible movements in rotation and in translation can substantially reach the entire internal volume of the transport container 20. More precisely, the possible movements of the rod 70 allow the tube 74 to sweep a cylindrical volume with a circular section of the same axis, the axis 52, as the axis of the tubular shape of the transport container 20.
- the two tubes 72 and 74 each comprising an internal channel, respectively 72a and 74a communicating with the suction duct 66.
- the tube 74 has at least one opening opening into the internal volume of the hermetic enclosure 50 and communicating with the internal channel, 74a. The opening allows the suction of the powder 18 located in the internal volume of the hermetic enclosure 50.
- the tube 74 sweeps the internal volume of the hermetic enclosure 50 in agitating the powder 18 and the opening, moving at least vertically, makes it possible to suck up almost all of the powder 18 present in the hermetic enclosure 50.
- the tube 74 extends along an axis 78 perpendicular to the axis 52.
- the tube 74 can extend along its axis 78 only on one side of the axis 52.
- the cane 70 has the shape of the letter L.
- the tube 74 advantageously extends symmetrically on either side of the axis 52 to take the form of the inverted letter T.
- the suction of the powder inside the hermetic enclosure 50 is done through one or more openings communicating the internal channel 74a before the internal volume of the hermetic enclosure 50. It is possible to make only one opening in the form of a slit extending over the entire length of the tube 74 in order to best scan the interior volume of the hermetic enclosure 50 during the translation and rotation movements of the rod 70 Alternatively, it is possible to reduce the section of the opening by making it only partly along the tube 74, for example on one side of the axis 52 only. provides greater suction. By carrying out translations and rotations of 360° around the axis 52, it is possible to reach the entire internal volume of the hermetic enclosure 50.
- the tube 74 has several openings opening into the hermetic enclosure 50 and communicating with the channel 74a.
- the tube 74 comprises six openings, 80, 82, 84, 86, 88 and 90 arranged asymmetrically on either side of the axis 52.
- the asymmetry makes it possible to scan the internal volume of the hermetic enclosure 50 while maintaining the smallest possible opening sections.
- the number of six openings is given only by way of example and it is possible to implement the invention with a smaller or larger number of openings.
- the openings 80 to 90 are arranged along the second tube 74 so as to cover a circular section of the hermetic enclosure 50 during a rotation of the rod 70 around axis 52.
- the circular section can be partial or complete. More precisely, the opening 80, furthest from the axis 52 can open up to the end of the tube 74 or at a short distance from the latter as shown in FIG. 3b. From 90% coverage of a complete section of the hermetic enclosure 50, very good suction results are obtained. After having carried out a complete translation of the rod 70 and several rotations combined with the translation, the hermetic enclosure 50 is almost empty.
- the openings 80 to 90 are all aligned. In other words, they all extend in the same plane containing the axis 78. In order to better suck up the powder that can settle on the bottom 56, this plane can be perpendicular to the bottom 56 and the openings are then directed towards the bottom 56. Alternatively, it is possible to make openings opening in different radial directions around the axis 78. It is for example possible to provide openings oriented towards the cover 58. In FIG. 3b, the openings 80 at 90 take the form of slots extending along the axis 78. Other opening shapes are also possible, for example helical slot shapes around the axis 78, circular hole shapes, etc. .
- the internal surfaces of the hermetic enclosure 50 can be covered with an anti-adherent coating making it possible to limit the adhesion of the powder to the walls of the hermetic enclosure 50.
- the choice of coating depends on the type of powder placed in the hermetic enclosure 50. It is for example possible to implement a coating based on fluorinated ethylene propylene known in the Anglo-Saxon literature under the name of "Fluorinated Ethylene Propylene" or its acronym: FEP .
- This type of coating is relatively fragile. It is particularly sensitive to the scratches that the tube 74 could make during the movements of the rod 70 if it were to touch the internal walls, in particular of the tubular part 54.
- plugs 92 can be put in place, even in the absence of non-stick coating.
- the tubes 72 and 74 can be made of metal alloy and the caps of plastic material. Plugs 92 can block channel 74a.
- FIG. 3c shows a variant of cap 93, one tubular face 94 of which is flush with the outer face 74b of the tube 74. This flush allows the tube 74 to descend lower into the hermetic enclosure 50 and to come into contact with the bottom 56.
- the caps 92 and 93 can be sealed. They may, alternatively, be pierced to aid suction. In this effect the cap 93 comprises an opening 95 extending along the axis 78 and communicating with the channel 74a.
- the suction generates a vacuum inside the hermetic enclosure 50. It is therefore useful to provide an air inlet 98 in the hermetic enclosure 50 to compensate for the vacuum.
- the air inlet 98 is for example placed across the lid 58.
- the air inlet 98 is provided with a calibrated filter to allow air to pass and retain the powder particles 18.
- a mechanism allowing the rotation and the translation of the rod 70 is located above the cover 58.
- the tube 72 can fit inside a larger diameter tube. But advantageously to simplify this mechanism, the tube 72 passes through an opening 100 of the cover 58.
- the opening 100 is centered around the axis 52 to allow the movements in translation and in rotation of the rod 70.
- the opening is provided with a bearing 102 allowing the tube 72 to be guided in rotation and in translation in the opening 100.
- the bearing 102 can be formed of a cylinder fixed to the cover and pierced along the axis 52.
- the tube 72 is fitted in the bore 104 of the cylinder.
- the opening 100 is also provided with means ensuring the tightness of the hermetic enclosure 50 at the level of the crossing of the lid 58 by the tube 72.
- the means ensuring the tightness are for example formed of a cable gland 106 secured to the cover 58.
- the stuffing box 106 contains a seal 108 held against the tube 72.
- the movements of the rod 70 in rotation and in translation can then be carried out directly by grasping the tube 72 above the cover 58.
- the tube 72 extending periodically outside the hermetic enclosure 50, it has no suction opening. All suction openings are located on tube 74. In other words, channel 72a communicates only with suction conduit 66 and with channel 74a.
- the cover 58 can include a transparent porthole allowing the operator to observe the interior of the hermetic enclosure 50. Through this porthole, the operator can also visualize the movement of the rod 70 and thus position openings 80 at 90 in the vicinity of possible clusters of powder along the walls of the hermetic enclosure 50. The window can be produced locally in the cover 58.
- the cover 58 mainly comprises a transparent glass plate 110 in which are formed the opening 100 and another opening to place the air inlet 98 provided with its filter.
- a strapping can surround the glass plate 110 to provide therein areas for attaching the latches 64.
- the tubular part 54 and even the bottom 56 can also be made of transparent glass in order to further improve the visibility of the interior of the hermetic enclosure 50.
- the hermetic enclosure 50 and more generally the entire transport container 20 must be able to mechanically withstand the stresses due to its use and in particular the manipulations inside and outside the box. gloves 12 as well as the depression due to the suction of the powder by the rod 70.
- the tubular part 54 and the bottom 56 are advantageously made of metal alloy.
- the various components of the hermetic enclosure 50 can be made with any type of material, homogeneous such as for example plastic or composite materials.
- the tubular part 54 and the bottom 56 can be assembled by any means or produced in a single mechanical part without assembly, for example by molding or 3D printing.
- the powder 18 may possibly become electrostatically charged inside the hermetic enclosure 50. Electrostatic charges may create a risk of explosion when the particles are flammable. To avoid this risk, it is possible to introduce an inert gas into the hermetic enclosure 50 through the air inlet 98. The presence of electrostatic charges can lead the powder 18 to agglomerate in the hermetic enclosure 50. The introduction of inert gas through the air inlet 98 does not allow the powder 18 to avoid agglomerating To avoid the formation of agglomerate, it is possible to provide a potential tap 112 connected to the metal components of the hermetic enclosure 50 and allowing the powder particles to be discharged.
- the hermetic enclosure 50 can be made of a metal alloy apart from the window or the transparent glass plate 110.
- the tubular part 54 and the bottom 56 can be made of a metal alloy to which the potential tap is connected. Tubes 72 and 74 can also be made in metal alloys.
- the bearing 102 can allow electrical conduction between the rod 70 and the potential tap 112. The electrostatic discharge also avoids the risk of explosion. It is thus no longer necessary to provide for the introduction of inert gas and the air inlet 98 can admit ambient air.
- the potential tap 112 can for example be connected to an electrical ground when handling the hermetic enclosure 50 inside the glove box 12 and also when emptying the powder 18 by suction.
- the tubes 72 and 74 can be made with any type of material, homogeneous such as for example plastic or composite materials.
- the assembly of the tubes 72 and 74 can be achieved by any means such as welding or gluing. It is also possible to produce the two tubes 72 and 74 of the rod 70 in a single mechanical part without assembly, for example by molding or 3D printing.
