Definitions
- the invention relates to an improved device, making it possible to optimize the transfer of pulverulent materials, of varying particle size. It also relates more specifically to the supply of powdered material under pressure to a pocket of a molten metal, for example intended for molding metal parts, and more specifically, aluminum.
- This powder is generally of acidic pH, and is intended to be mixed with the molten metal to optimize the qualities required thereof depending on the parts to be produced.
- the object of the invention is therefore first of all to propose a device making it possible to transfer pulverulent materials of variable particle size using a pressurized fluid. Furthermore, it is aimed at a device which makes it possible to overcome the various aforementioned drawbacks.
- a device for the transfer of pulverulent materials comprising: M an enclosure in which the pulverulent material to be transferred is agitated and pressurized, enclosure at the lower end of which a pipe conveys said material in the direction of its destination ;
- M an inlet for gas, and in particular compressed air, emerging at the level of the pipe, and suitable for ensuring the progression of the material towards said place.
- This device is characterized in that at the gas inlet, said pipe forms a nozzle, directed in the direction of flow of the material, said nozzle opening into a second pipe, substantially of the same diameter as the first, and in that the gas inlet opens at the lower end of the first pipe, outside the nozzle, said gas entering the second pipe by means of a plurality of through orifices formed substantially in the same plane as the lower end of the nozzle, and oriented substantially parallel to the direction of flow of the pulverulent material.
- the invention consists first of all in giving the pipeline a particular profile, in particular in the form of a nozzle, known to impose on a flowing fluid an increase in its speed, this increase in speed being in further optimized by the orientation of the gas flow intended to ensure the progression of the pulverulent material.
- the device comprises two gas supplies, distributed diametrically relative to the pipe.
- the joining of the first and second pipes is obtained by means of a ring, at the level of which the gas inlet pipes terminate.
- the invention relates more specifically to the supply of powder under pressure to a bath of molten metal.
- This device for supplying powder under pressure to a bath of molten metal comprising: “an enclosure, in which the powder is agitated and pressurized, enclosure at the lower end of which a pipe conveys the powder towards the molten metal bath; M an inlet for neutral gas, opening at the level of the pipe, and suitable for ensuring the progression of the powder towards said bath; is characterized in that at the neutral gas inlet, said pipe forms a nozzle, directed in the direction of flow of the powder, said nozzle opening into a second pipe, substantially of the same diameter as the first, and in that the arrival of neutral gas opens at the lower end of the first pipe, outside the nozzle, said gas entering the second pipe by means of a plurality of through orifices formed substantially in the same plane as the lower end of the nozzle, and oriented substantially parallel to the direction of flow of the powder.
- the two pipes are secured to one another by means of rings.
- One of the rings is also provided with two lateral orifices, diametrically distributed with respect to its generator, at the level of which the inlets of neutral gas terminate.
- the device may have more than two inlets of neutral gas, and in this case, the ring in question is provided with as many lateral orifices.
- said ring comprises a partition, oriented perpendicularly to the direction of flow of the powder, and pierced on the one hand, with a central orifice, in order to allow the introduction at this level of the lower end of the nozzle, and on the other hand, through orifices, peripheral with respect to the central orifice, and oriented parallel to said direction of flow, and intended to allow the passage of gas under pressure in the direction of the pipe.
- this device is more particularly intended for aluminum foundries.
- Figure 1 is a side view of the installation according to the invention.
- Figure 2 is a front view of the installation of Figure 1.
- Figure 3 is a longitudinal sectional view of the device according to the invention.
- Figure 4 is a schematic view partially showing the securing ring of two pipes, according to the invention.
- Figure 5 is a bottom view of said ring.
- the invention is more particularly described in relation to a device for supplying a bath of liquid metal with a pulverulent material. However, it cannot be limited to this single application, and any device for transferring pulverulent material is also covered by the present invention.
- FIG 1 a side view of the installation according to the invention.
- This basically consists of a chassis (1) mounted on casters (2) to allow its movement, one or more of the rollers being provided with a braking system, in order to promote the stability of the together.
- This tabular or metallic frame (1) receives an enclosure (3), in this case of frustoconical shape, within which is stored the acid pH powder to be incorporated in the molten metal, for example aluminum.
- This powder is stirred by means of a paddle stirrer (5), driven by an electric motor, also not shown.
- This enclosure (3) is provided with an access and filling hatch, positioned on its upper face, and capable of being closed by means of a sealed cover (4), in order to be able to keep the powder under pressure.
- the lower end (7) of the tank (3) is extended by a first pipe (8), of determined diameter. Nevertheless, and advantageously, an alveolar distributor (6) is inserted between the lower end (7) and the first pipe (8), intended to calibrate in a known and determined manner, the quantity of powder to be injected into the molten metal.
- Such cellular distributors are in themselves well known, so there is no need to describe them here in more detail.
- This alveolar distributor (6) is advantageously managed by means of a programmable automaton, the electrical cabinet of which is represented by the reference (11).
- the lower end of the first pipe (8) ends in a nozzle (12), the own lower end of which (13 ) ends in a second canahsation (9), of identical or substantially identical diameter to that of the canaHsation (8).
- These two pipes are secured to one another by means of two rings (10, 22), as can be seen in Figure 3.
- This nozzle increases the speed of flow of the powder at this level, and leaving in the pipe (9).
- the ring (10) end at the level of the ring (10) two pipes (14) and (15) of arrival of neutral gas, in particular argon, under determined pressure.
- the ring (10) is provided with two lateral orifices, diametrically distributed with respect to its generator, at the level of which the neutral gas pipes (14, 15) terminate.
- the pressure is in fact dependent on the flow rate, this being managed by means of variable flow valves (known under the name SMC), controlled in 0-10 volts by the programmable controller (11).
- SMC variable flow valves
- the gas arrives at the level of the ring (10) outside the nozzle (12), and is introduced at the level of the pipe (9) substantially at the same level as the 'lower end (13) of the nozzle.
- the ring (10) is provided with a partition (19) perpendicular to the direction of flow of the powder, pierced on the one hand, with a central opening (23), in order to allow the introduction at this level of the lower end (13) of the nozzle (12), and on the other hand, peripheral through orifices (20), oriented parallel to said direction of flow, and intended to allow the passage of gas under pressure in the direction of the pipeline (9).
- FIG. 5 shows a view from below of said ring (10), in which six of these orifices (20) have been represented. Obviously, the number indicated is purely illustrative and in no way limitative.
- the pipe (9) is fixed to the pipe (8) by means of a ring (22) attached to the ring (10) by means of screws inserted in threaded or threaded orifices (21) formed within the ring (10).
- O-rings or lip seals (16), (17) and (18) are in place in order to ensure watertightness, in particular with respect to the neutral gas, and therefore of the entire installation.
