Definitions
- the invention relates to a device and a method for handling 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 introduction can be carried out through a door provided in the enclosure.
- the door When handling powders in the enclosure, the door is closed tightly. To be able to open the door, it is necessary to eliminate all traces of powder located in the enclosure, for example by means of a filtration system equipped with a vacuum cleaner capable of treating the air, the interior surfaces of the enclosure and any object located inside the enclosure. If there is a risk of explosion, it is necessary to restore an acceptable proportion of oxygen after eliminating the powders. These operations are cumbersome and costly.
- the invention aims to provide a much simpler solution for introducing volatile powders into an enclosure where they are handled.
- the subject of the invention is a device for handling volatile powders comprising a hermetic enclosure comprising a hatch making it possible to close an opening arranged across a wall of the hermetic enclosure, outside the hermetic enclosure the device comprising:
- a telescopic skirt arranged so as to surround the flexible container, the telescopic skirt being fixed on the one hand to the support and on the other hand to the wall of the hermetic enclosure, the telescopic skirt being configured to retract and expand according to displacements of the support while retaining a substantially tubular shape and a section of substantially constant shape around the flexible container.
- the telescopic skirt is configured so that when the movable support approaches the opening, a characteristic dimension of an inner section of the telescopic skirt decreases so as to tighten the flexible container.
- the hermetic enclosure comprises a flange surrounding the opening of the hermetic enclosure and extending beyond the wall towards the outside of the hermetic enclosure.
- the flexible container is configured to cover the collar at its opening, and a seal seals between the collar and the flexible container.
- the seal is advantageously incorporated into a ply of the flexible container.
- the device advantageously comprises an entry lock fixed to the hermetic enclosure and in which are placed the flexible container, the mobile support and, where applicable, the skirt.
- the device advantageously comprises means for sealing the flexible container.
- the sealing means can be configured to weld the flexible container along several strips each capable of ensuring the sealing of the flexible container.
- the hermetic enclosure can be a glove box.
- the gantry moving mechanism may include an actuator configured to be operated by means of a foot pedal arranged such that an operator can operate the foot pedal while keeping hands in glove box gloves.
- the invention also relates to a method for handling volatile powders by means of a device according to the invention, the method comprising a sequence of the following operations:
- the method for handling volatile powders may also comprise the following operations:
- the sealing operation of the flexible container is advantageously carried out by means of several welding strips of the flexible container, each of which can seal the flexible container, the operation of separating the flexible container being carried out by cutting the container flexible between the extreme welding bands.
- FIG. 1 schematically shows an example of a manipulation device according to the invention
- FIG. 2 shows in more detail a flexible container of the device of Figure 1;
- FIG. 3 shows an alternative embodiment of the flexible container.
- FIG. 1 shows a device 10 for handling volatile powders.
- the device comprises a hermetic enclosure 12 in which the powders are handled.
- the hermetic enclosure 12 is mainly formed of a glove box. More specifically the hermetic enclosure 12 comprises orifices 14, four in the example shown, allowing an operator standing outside the hermetic enclosure 12 to insert his hands inside the hermetic enclosure through sealed gloves attached to the wall of the sealed enclosure 12.
- a glove box allows an operator to handle products or objects located in the sealed enclosure without being in direct contact with the interior of the hermetic enclosure 12.
- handling may consist of a sample being taken from a first transport container, weighing a quantity of products in order to place it in a second transport container.
- the first container makes it possible to fill several second containers.
- the first container can come from a powder manufacturer and the second container can be used for transfer to a reactor separate from the hermetic enclosure and in which the powder is used, for example, to be embedded in a resin matrix. It is understood that the removal of a precise quantity of powder is only one example of manipulation.
- the invention can be implemented for any type of manipulation carried out in the hermetic enclosure. It is for example possible to mix the powder and the resin in the hermetic enclosure 12.
- the invention relates to the introduction of products into the hermetic enclosure 12.
- the hermetic enclosure 12 comprises an opening 16 arranged across a wall 18 of the hermetic enclosure 12 and a hatch 20 allowing the opening 16 to be opened and closed which allows products to be introduced inside the hermetic enclosure 12 in order to be handled there. Once closed, the hatch 20 is sealed.
- the volatile powder 22 is delivered in a sealed packaging 24 which is placed in a flexible container 26 adapted to the device 10. More precisely the flexible container 26 has an opening 28 configured to fit the opening 16 in a sealed manner. of the hermetic enclosure 12.
- the hermetic enclosure 12 comprises a collar 30 surrounding the opening 16 and projecting from the wall 18 towards the outside of the hermetic enclosure 12.
- the flexible container 26 covers the collar 30 at its opening 28.
- a seal 32 is interposed between the collar 30 and the flexible container 26.
- the seal 32 is for example an O-ring.
- a flange 34 surrounds the flexible container 26 at its opening 28 and makes it possible to compress, radially around the opening 16, the joint sealing 32. Any other means allowing the flexible container 26 to come tightly marry the opening 16 of the sealed enclosure 12 is possible.
- the flexible container 26 is sandwiched in the tapered fitting. The tightening of the flange is done, in this alternative, perpendicular to the wall 18 along the axis of the conical fitting.
- the hatch 20 is closed.
- the packaging 24 is sealed allowing it to be handled without danger of contact with the volatile powder 22.
- the packaging 24, still sealed is placed inside the flexible container 26.
- the flexible container 26 is put in place so fitting the opening 16 in a leaktight manner.
- this fitting consists more precisely of placing the flexible container 26 around the flange 30 while maintaining the seal 32 between the flexible container 26 and the collar 30 and then tightening the flange 34 around the flexible container 26 so as to compress the seal 32 between the flexible container 26 and the collar 30. around the opening 16, it is possible to open the hatch 20.
- the interior of the flexible container 26 then communicates with the interior of the hermetic enclosure 12 which allows the operator to grasp the packaging 24 and to break its seal to access er to volatile powder 22.
- the device 10 When the packaging 24 is full, its level in the packaging 24 is close to the opening 16 and the operator can access the powders through the opening 16. As the operator draws powder 22 in the packaging 24, its level drops and the operator may have difficulty drawing from the packaging 24.
- the device 10 comprises a mobile support 36 on which the flexible container 26 rests.
- the support 36 is mobile in translation along an axis 38. The mobility in translation allows the support 36 to approach the opening 16, carrying in its translation the flexible container 26 and the packaging 24.
- the device 10 also comprises a mechanism 40 for moving the support 36 in translation in the direction of the opening 16. This mechanism can be manual.
- the support can be guided in translation along a rod 42 extending along the axis 38.
- a handle 43 secured to the support 36 allows the movement of the support 36.
- the maintenance in position of the support 36 along the rod 42 is for example ensured by bracing by means of the weight of the support 36.
- Associate a pinion integral with a handle makes it possible to move the support 36 in translation along the rod 42 by engagement of the pinion on the rack.
- the mechanism 40 for moving the support 36 in translation can be motorized.
- the device 10 comprises an actuator 44 making it possible to move the support 36 in translation along the axis 38.
- the control of the actuator 44 is advantageously carried out by a pedal 45 configured to be accessible by the operator when he carries out manipulations in the hermetic enclosure 12, his hands in the gloves placed in the orifices 14.
- a pedal 45 configured to be accessible by the operator when he carries out manipulations in the hermetic enclosure 12, his hands in the gloves placed in the orifices 14.
- any means of moving the support 36 is possible within the scope of the invention.
- the flexible container 26 When the support 36 causes the bottom of the flexible container 26 towards the opening 16, the flexible container 26 can be deformed so as to shrink the dimensions of its opening 28 below its retention at the collar 30. More precisely , during the ascent of the support 36 in the direction of the opening 16, the flexible container 26 can bend while sagging, thus causing a flattening of its section perpendicular to the axis 38. The operator can take care to avoid this phenomenon by placing a tool in the soup container 26 or even in the packaging 24 during the translation of the support 36 in the direction of the opening 16. Alternatively, it is advantageous to provide means limiting the risk of narrowing of the opening 28 These means comprise for example a telescopic skirt 46 surrounding the flexible container 26.
- the skirt 46 is fixed on the one hand to the support 36 and on the other hand to the wall 18 of the hermetic enclosure 12.
- One of the fixings of the skirt 46 either in support 36, or to the wall 18 is removable in order to access the flange 34.
- the fixing of the skirt 46 to the wall 18 is chosen as the removable fixing.
- the skirt 46 is configured to retract and expand according to movements of the support 36, while retaining a substantially tubular shape. around the flexible container 26.
- the skirt 46 retains a section, perpendicular to the axis 38, of substantially constant shape.
- substantially constant is meant a section varying in a given proportion by its retraction and its expansion.
- the section of the skirt 46 can be circular and remain substantially circular during the movements of the support 36.
- the diameter of the skirt 46 varies little during its retraction and its expansion.
- Other section shapes of the skirt 4 are possible within the scope of the invention, for example an oval, polygonal shape, etc.
- the presence of the skirt 46 makes it possible to guide the flexible container 26 when the support 36 moves. in translation, thus limiting the risk of the opening 28 of the flexible container 26 shrinking below the flange 30.
- the skirt 46 is for example formed of a deformable film to which is fixed an elastic metal wire winding in a helix around the flexible container 26.
- the wire ensures the rigidity of the skirt 46.
- the wire deforms in the same way of a coil spring retaining a substantially tubular shape.
- Other embodiments of the skirt 46 can be considered within the scope of the invention.
- the skirt 46 can for example be formed from alternating truncated cones all extending along the same axis parallel to the axis 38. The angles at the top of the various truncated cones increase when the skirt 46 retracts and decrease when the skirt 46 expands. The skirt 46 then deforms like an accordion.
- the skirt 46 is configured so that when the movable support 36 approaches the opening 16, the diameter d of the inner section of the skirt 46 and more generally a characteristic dimension of the section decreases so as to tighten the flexible container 26.
- the skirt 46 than alternating truncated cones are possible to allow the variation of the inner section of the skirt 46. It is for example possible to equip the skirt with several retractable rings depending on the elongation of the skirt 46.
- the flexible container 26 and the skirt 46 when present, are fragile components. More specifically, a risk of puncturing by external elements exists and can lead to leaks of volatile powder in the environment of the device 10.
- the device 10 can comprise an entry lock 50 in the form of a box fixed to the enclosure hermetic 12 and in which the flexible container 26, the mobile support 36 and, if necessary, the skirt 46 are arranged. 50.
- the airlock 50 advantageously comprises a door allowing access to the flexible container 26 in order to put it in place.
- the handling of the volatile powder is carried out inside the hermetic enclosure 12 by the operator. More precisely, the operator draws volatile powder 22 from the packaging 24 then manipulates it in the hermetic enclosure 12. This manipulation consists for example of filling an outlet container 52. The filling is accompanied by a weighing allowing the quantity of powder 22 present in the outlet container 52 to be dosed with precision. A scale 54 allowing the weighing is represented schematically in the hermetic enclosure 12.
- the device 10 further comprises an outlet lock 60 for receiving the powder 22 in different outlet containers 52.
- the outlet lock 60 is, like the inlet lock 50, fixed to the hermetic enclosure 12.
- the outlet lock 60 can be sized to receive several outlet containers 52. From inside the hermetic enclosure 12, the outlet lock 60 is accessed through an opening 62 made in the wall 18 of the hermetic enclosure 12.
- a hatch 64 makes it possible to isolate the hermetic enclosure 12 from the exit lock 60 by closing the opening 62.
- the volatile powders 22 may present flammability risks. This is particularly the case when the volatile powders 22 are formed from microballoons enclosing a flammable gas. To ensure the safety of the operator, it is possible to deplete the oxygen in the air present in the hermetic enclosure 12.
- the ambient air contains around 20% oxygen and the target oxygen level to be observed in the hermetic enclosure 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 so-called lost sweeping technique. More precisely, a permanent flow of inert gas, such as for example nitrogen, sweeps the interior of the hermetic enclosure 12.
- a filter allows the excess air to leave the hermetic enclosure 12.
- the filter is calibrated to allow air to pass and retain the particles of powder handled in the hermetic enclosure 12.
- the sweeping is schematized by a nitrogen reserve 66 able to inject nitrogen into the hermetic enclosure 12 and a filter 68 arranged in passing through the wall 18.
- the sweep is configured so as to reach the entire volume of the hermetic enclosure 12, the interior of the flexible container 26 as well as the volume of the outlet lock 60.
- the oxygen depletion system may have a sensor for measuring the oxygen level allowing it to regulate its operation. In the case of volatile powders presenting risks of flammability, once the seal has been made between the flexible container 26 and the hermetic enclosure 12 around the opening 16, the oxygen depletion of the internal volume of the hermetic enclosure 12 is carried out before opening the hatch 20.
- the gas pressure inside the hermetic enclosure 12 can be maintained slightly higher than the atmospheric pressure prevailing in the room in which the device 10 is located.
- the overpressure thus prevents the ambient air of the room from entering the hermetic enclosure through any micro leaks or through the gloves which tend to become porous over time.
- a system for cleaning the internal volume of the hermetic enclosure 12 can be provided in order to eliminate the particles of powder 22 which may be deposited in the hermetic enclosure 12 out of the outlet container 52 during the handling of the powder. 22.
- the device 10 may comprise a vacuum cleaner 70 provided with a filter 72 similar to the filter 68.
- the vacuum cleaner 70 can be equipped with pipes, not shown, allowing the operator to reach the entire volume of the hermetic enclosure 12 and also the interior of the flexible container 26 and of the outlet lock 60. It is also possible to provide a specific vacuum cleaner for the outlet lock 60 in order to avoid completely cleaning the internal volume of the enclosure hermetic 12 when the operator wishes to access the outlet lock 60 to take a full outlet container 52 or to deposit an empty outlet container 52 there.
- the exit lock 60 includes a door 74 allowing the exit containers 52 filled with their dose of powder 22 to be removed and also allowing the introduction of empty exit containers 52 for filling into the enclosure. hermetic 12.
- the hatch 64 is closed during the handling of powders inside the hermetic enclosure 12.
- the interior of the hermetic enclosure 12 and in particular the outer surfaces of the outlet containers 52 are cleaned by means of the vacuum cleaner 70 before opening the hatch 64.
- the internal volume of the outlet lock 60 remains clean even when the hatch 64 is open.
- the device has an oxygen depletion system for the air present in the hermetic enclosure 12, it may be useful to provide a system for restoring oxygen to the outlet airlock 60 in order to prevent the operator is subjected to air that is too low in oxygen by opening the door 74.
- This oxygen replenishment system can use a compressed air network often present in premises of the type to which the device 10 is brought to be installed.
- the oxygen replenishment system is activated after cleaning the inside of the hermetic enclosure 12 to prevent traces of powder from being in the presence of gas that is too rich in oxygen.
- the oxygen replenishment system may have a sensor for measuring the oxygen level allowing it to regulate its operation. It is also possible to actuate it when the hatch 64 is open, but this requires replenishing the entire volume of the hermetic enclosure with oxygen, to carry out this operation, which consumes inert gas before a new powder handling operation 22 inside the hermetic enclosure 12.
- FIG. 2 shows in more detail the flexible container 26 which can be used to extract waste from the device 10 and in particular the packaging 24 when it is empty.
- the device 10 comprises means for sealing the flexible container 26.
- the flexible container 26 can be made of a thermoplastic material and the sealing means can consist of a heating clamp 80 allowing the sealing of the sealed container 26 in particular to enclose the packaging 24 therein once emptied of its powder and possibly any other type of waste, such as a vacuum cleaner bag 70, which the operator can place in the flexible container 26 before it is closed.
- Other means of closures are of course possible within the scope of the invention. It is for example possible to fold the flexible container and maintain the fold by means of clamps.
- a single welding strip may be sufficient to seal the flexible container 26.
- Weld strip 82 is closest to opening 16 and strip 86 furthest away. Each welding strip can alone seal the flexible container 26.
- the heating clamp 80 can be configured to make only one strip and the operator repeats the welding operation as many times as there are strips to be made. Alternatively, the heating clamp 80 can be configured to produce the three bands simultaneously. This allows better control of the gap between the different welding strips.
- the flexible container 26 can be cut using any type of cutting tool between the two end strips 82 and 86 and in particular on the trace of the intermediate strip 84 when three strips are carried out.
- the strip 84 then serves as a guide for cutting the flexible container 26.
- the strips being made at a distance from each other, the use of a cutting guide makes it possible to limit the risk of rupture of the seal. of the flexible container 26 during the cutting operation.
- the cutting of the flexible container 26 on the strip 84 has another advantage, which is to prevent any powder particles that may be between two consecutive strips from being released.
- the flexible container 26 is cut into two parts, the part 26-1, the closest to the opening 16, remains attached to the collar 30 and the other part 26-2 can be removed, for example for treatment of waste and recycling.
- FIG. 3 shows an alternative embodiment of the flexible container 26 and more specifically of the seal placed at the interface between the flange 30 and the flexible container 26. More specifically, the seal 32 can be placed in a fold 90 of the flexible container 26. It is possible to fold the edge of the flexible container 26 at the level of its opening 28, to enclose the seal 32 in the fold 90 and to fix this fold to the rest of the flexible container 26.
- Fastening can be carried out in various ways, for example by welding or gluing.
- the presence of the seal 32 in the fold 90 of the flexible container 26 makes it possible to limit the number of operations that the operator must perform when mounting the flexible container 26 on the collar 30. This also makes it possible to secure this assembly, forgetting the seal 32 is then impossible.
- the seal 32 can be single or multiple as shown in Figure 3. Inside the fold 90, it is possible to separate the seals 32 by a bead of glue or welding.
