Definitions

  • the present invention relates to a device for loading fitted with a flow adjustment device, for supply an enclosure with a predetermined flow rate of one solid matter.
  • It relates more particularly to a device for charging to supply an enclosure with a flow predetermined solid material
  • a device for charging to supply an enclosure with a flow predetermined solid material comprising: a hopper with material provided with a funnel-shaped lower part, which defines a central flow axis substantially vertical; a supply pipe to the enclosure, which is located axially below said part lower of the material hopper; and a retainer and adjusting the material flow.
  • Such a device which is designed to equip a tank fitted with a rotary distribution chute or oscillating, is known from patent specification EP-62,770.
  • a retainer and adjustment of the combined material flow which includes two registers in the form of spherical caps. Movement relative of these two caps allows to vary the section of symmetrical passage around the central flow axis of the material.
  • These registers are arranged in a room waterproof, located directly below the hopper.
  • This sealed chamber is provided at its lower end with the lower sealing member.
  • This includes a valve which can be swiveled between a lateral position, in which it is sheltered from the discharged material hopper, and a closed position, in which it is transverse to the axis of flow of the material. In this shutter position the valve is applicable, for an axial translational movement, on a seat.
  • This seat peripherally surrounds the discharge opening of the hopper and has a sealing surface facing bottom, i.e. in the direction of flow of the matter.
  • a device of the kind described in the booklet of Patent EP-62,770 knows how to give complete satisfaction of the point characteristic view of flow and point adjustment sealing view, even for an enclosure in which high working pressures prevail. Its only disadvantage is its high mounting height, which results the fact that the combined retaining and adjusting member of the material flow and the sealing member are superimposed below the hopper. In order to remedy, if necessary, to this disadvantage, one could for example think of replace the flow control device located below the hopper, by a flow control member which is directly integrated into the hopper.
  • Patent specification EP-88 253 also provides a lower sealing member which is integrated into the hopper.
  • This includes a shutter disc, which is arranged below the bell and provided with a seal of peripheral sealing on the side of its lower face.
  • the disc When the bell is resting on its seat, the disc can be applied axially on a second seat.
  • This last which is located below said first seat, has a smaller passage section than this and is provided a sealing surface facing the interior of the hopper.
  • This waterproof member does not, however, satisfaction. Indeed, said second seat, which is exposed to wear by materials flowing through the discharge opening, is rapidly deteriorated and does not can no longer ensure a gas-tight shutter under pressure.
  • the objective of the present invention is to provide a loading device, of the kind described in the preamble, in which the retaining and adjusting member of the material flow is integrated in the hopper, but which not all the disadvantages mentioned above for the device of patent specification EP-88 253.
  • a loading device for supply an enclosure with a predetermined flow rate of one solid material, comprising a material hopper provided with a funnel-shaped lower part which defines an axis substantially vertical flow central, a tubing supply to the enclosure, which is located axially below of said lower part of the hopper, an organ retaining and adjusting the material flow which encompasses a bell movable in the hopper between a position lower shutter of a discharge opening in said lower part of the hopper and a position upper lift, and a central oblong metering body and significantly more slender than the bell, coaxial with said axis central flow of the material and movable along the latter so as to penetrate more or less through said discharge opening towards the tubing supply, characterized in that the bell and the body dosing units are relatively movable one by relative to each other, so that the vertical distance that separates the two is freely adjustable.
  • the term "bell" also encompasses a retaining body which does not necessarily have the shape of a bell.
  • the central metering body is no longer a component of the bell, but a independent element, whose position in relation to the discharge opening can be adjusted independently relative to the position of the bell in the hopper matter.
  • This feature allows the bell to be placed a distance from the discharge opening, in which it almost no longer influences the flow rate flowing through this one.
  • This flow can therefore be essentially regulated by moving the central dosing body.
  • Another advantage of the proposed device lies in the fact that the position of the bell in the hopper can be varied freely upstream of the position in which it almost no longer influences the flow rate flowing through the discharge opening.
  • This possibility of power vary the location of the bell in the hopper, without as much act on the flow, allows to choose for the bell a location in the hopper in which it influences optimally homogeneity of the flow of matter inside the hopper.
  • This well-known phenomenon finds its origin in the fact that the finer particles have tendency to flow through the center of the hopper, while the larger particles rather flow along the walls.
  • the central body of dosage includes a lower trunk, which first flares out of the bottom up and ending in one end upper which tapers towards a rod ordered.
  • the lower trunk acts as an element of setting.
  • the upper end on the other hand, is designed so as to influence as little as possible the flow of material, i.e. the setting characteristic.
  • the bell is provided with a hollow or a cavity in which the central metering body is fully removable, for example when the bell is in its lower position closing the opening of flow. It follows that there is, in position shutter of the discharge opening, no more elements which penetrates through it.
  • the device can be installed on an enclosure under pressure, for example a shaft furnace.
  • the hopper is then used from a solid lock container to load into the pressure vessel.
  • such a body lower seal includes a valve which can be swiveled between a lateral position, in which it protected from the material discharged from the hopper, and a closed position, in which it is transverse to the axis of flow of the material and in which it can be applied axially on a seat.
  • the latter surrounds peripherally the hopper discharge opening and has a downward facing sealing surface. It will be noted that this sealing member is not exposed the wear of materials flowing from the opening of discharge from the material hopper.
  • the sealing valve can also be directly mounted downstream of the discharge opening; which allows achieve a significant gain in mounting height by relative to the known device of the patent specification EP-62,770.
  • a lower sealing member comprising: a obturation element arranged directly below the bell and axially movable relative to it, said closure element being provided with a surface lateral device in which a seal is integrated inflatable seal and a central opening of passage for the central metering body; means for move the obturator axially between a protected position below the bell and a position operational outside the bell, when this the latter is in said lower shutter position; and a seat mounted axially below the opening of discharge, said seat being provided with a first surface seal that faces down and surrounds said inflatable seal when the closure element is located in said operational position.
  • This organ lower seal reduces the height of mounting the loading device even more.
  • the bell is fitted with an upper sleeve which is extended upwards outside the hopper.
  • This sleeve allows to introduce and extract the central metering body through this sleeve and at the same time constitutes an axial guide of the central body dosing.
  • At least one first cylinder located outside of the material hopper is connected between the latter and the muff. This or these first cylinders are sized for provide the necessary effort to raise the bell to through matter.
  • the central dosing body is provided a coaxial rod which is guided axially inside sleeve, and at least one second cylinder is connected axially between the sleeve and this rod. This second cylinder is slaved to the first cylinder (s), so that a stroke (c) of the bell in a first direction simultaneously causes a stroke (c) of the central body of dosing in the opposite direction.
  • the hopper is provided with a fixed guide sleeve which extends axially from top to bottom inside the material hopper.
  • the bell is provided with an upper sleeve which is can be engaged on this fixed sleeve.
  • the central dosing body is fitted with a coaxial rod which is guided axially to inside the fixed sleeve.
  • At least one first cylinder is connected between the hopper and said upper sleeve, and at minus a second cylinder is connected between the hopper and the rod inside the fixed sleeve.
  • FIG. 1 shows an embodiment of a charging device according to the present invention, designed to equip a shaft oven.
  • the reference 10 marks a housing of a drive mechanism of a chute rotary or oscillating distribution (not shown).
  • the reference 12 marks the vertical axis of the shaft furnace.
  • a supply pipe 14 axially passes through the casing 10 to feed the distribution chute with a material loading, for example coke, chipboard, pellets etc. This supply pipe 14 is coaxial to the vertical axis 12 of the shaft furnace.
  • Reference 18 globally identifies a hopper with material, which constitutes a lock container for the loading material of the shaft furnace. This matter of loading is marked inside the hopper 18 by the reference 20.
  • the material hopper 18 comprises a part upper 22, in the form of a cylinder coaxial with the axis vertical 12. In this upper part 22 are arranged two loading openings 24 and 26, through which the hopper can be filled. The filling is done by example, in a manner known per se, through two skip carriers 28 and 30.
  • Each of these loading openings 24 and 26 is equipped with an upper sealing valve 32 and 34.
  • These upper sealing valves guarantee, in position closed, the tightness of the hopper with respect to the outside atmosphere.
  • Figure 1 they are shown, in dashed lines, in the open position. We notes that they are, in this position, each located in a lateral tube 36, 38 of the hopper, well at protected from the material discharged by the skips 28, 30 to through the loading openings 24 and 26.
  • Each of these pipes 36, 38 is provided with a flange shutter 40, 42 removable, which allows access to respective valve for maintenance work.
  • the upper part 22 of the material hopper 18 is extends into a lower part 44, which has the shape of a funnel or trunk of coaxial cone of revolution to the axis 12.
  • the angle at the top of the cone of revolution is by example between and 60 ° and 80 °, which corresponds to a slope of an internal wall 46 of the order of 50 ° to 60 °.
  • a lower opening 48, coaxial with axis 12, is provided with a sealing member 50.
  • the latter ensures, in closed position, tightness of the hopper 18 relative to in the oven.
  • the sealing member 50 comprises a valve sealing 52, pivotable from a lateral position (shown in broken lines in Figures 1 and 2), in which it is sheltered from matter flowing from the opening 48, in a position shutter, in which it is transverse to the axis 12.
  • the valve 52 can be applied, in a manner known per se, axially on a seat 54, peripherally surrounding the opening 48 and provided a sealing surface 56 which is oriented downwards.
  • the space required to pivot the valve 52 below of the hopper 18 is obtained by connecting the latter to using a sealed chamber 58 to the tubing supply 14.
  • a side tube 60 provided with a removable flange 62, allows access to inside the sealed chamber 58, to replace the valve 52 or seat 54.
  • Reference 64 globally identifies the retaining member and material adjustment.
  • the latter includes a bell 66 and a central metering body 68, displaceable one relative to the other along axis 12.
  • the bell 66 has the shape of a hollow truncated cone, which is coaxial with axis 12 and which flares towards a lower horizontal edge 70.
  • the bell is shown in a closed position. She is supported with its lower edge 70 on the wall interior 46 of the hopper 18, so as to seal a passage section 72 in the conical part of the hopper 18, upstream of the sealing member 50.
  • this passage section constitutes a discharge opening 72 of the hopper 18, which can be closed by the bell 66 and which can be released in removing the bell 66 upwards.
  • the central metering body 68 has an oblong shape, significantly more slender than the bell 66. It is by example of a body of revolution composed of two trunks of cone 74, 76 superimposed, which widen from the bottom to the top and which define the actual adjustment profile. AT its upper end 78, this body of revolution gradually thins towards a stem support 80, which is coaxial with axis 12.
  • the choice of profile of the central metering body 68 is determined, ie experimentally, either by calculations. What matters is that the central metering body 68 is oblong and above all significantly more slender than the bell 66.
  • the axial positioning of the central metering body 68 in the lower opening 48 of the hopper 18 delimits therein an annular passage opening.
  • the section of this annular passage opening is determined by the cross section of the central body of dosage 68 at this lower opening 48.
  • the bell 66 is provided at its end upper of a sleeve 82, which is extended axially upwards outside the material hopper 18.
  • a axial sealing device 84 for example a device of the type of a cable gland, provides axial guidance and the sealing of the sleeve 82 through an upper wall of the hopper 18.
  • Two cylinders 86 and 88 are connected between arms 90 and 92, integral with the upper end of the sleeve 82, and the hopper 18. These jacks 86 and 88 must be sized to provide the necessary effort allowing the bell 66 to be raised through the material 20.
  • a third cylinder 94 is tightly mounted on the upper end of the sleeve 82.
  • Its rod 96 penetrates axially in the sleeve 82, where it is connected to the upper end of the rod 80 of the central body of metering 68.
  • This rod 80 is guided inside the sleeve 82 during its vertical displacement relative to the hopper 18.
  • a regulator 100 ensures that a displacement of stroke (c) of cylinders 86 and 88 in one direction, causes a synchronous displacement movement (c) of the cylinder 94 in the opposite.
  • the regulator 100 therefore makes it possible to keep the central metering body 68 stationary by compared to the hopper 18, when the bell 66 is raised or lowered by cylinders 86 and 88.
  • the bell 66 is provided at its end upper part of a sleeve 102, which is axially engaged on a fixed sleeve 104.

  • This rod 80 is guided axially inside the fixed sleeve 104, during its vertical displacement relative to the hopper at material 18.
  • a cylindrical cage 118 surrounds the rods of cylinders 110 and 112, to protect them against contamination and wear by the loading material.
  • the bell 66 is in its position raised in which it releases the opening of discharge 72. Its position in matter 20 will be chosen from so as to have a minimal influence on the flow of material flowing through the discharge opening 72 and maximum influence on the homogeneity of the emptying of the material hopper 18.
  • the bell travel will be, for therefore, determined according to the particle size and the nature of the loading material. It could be adjusted according to the level of loading in the hopper 18, which naturally lowers during emptying of it. This adjustment will be done, for example, automatically based on an output signal from a hopper continuous weighing device 18.
  • Figure 6 shows a variant of the device of Figures 1 and 2.
  • the Figure 6 device includes a sealing member lower 200, which is fully integrated into the hopper to matter 18.
  • This member 200 comprises a seat 202, which is tightly mounted on the hopper 18 at the lower opening 48, and a closure element 204, having the shape of a crown.
  • the crown-shaped closure element 204 is tightly attached to the lower end of a sleeve 206, in which a central metering member 208, equivalent to the metering member 68 of FIG. 1 or 2, can be removed.

  • This channel 282 is equipped with go connection pipes and back for a liquid.
  • These lines are schematically represented by arrows 284 and 286 on Figure 2.
  • Reference 288 schematically represents a liquid packaging unit, which ensures that the temperature of the liquid circulating in the channel annular 282 is such that the surface temperature of the sealing surfaces 276 and 278 is never lower at dew point, to avoid condensation, and never higher than an upper limit temperature, determined for example by the working temperature limit a seal applied against one of the two surfaces 276 and 278.
  • the shutter element 204 in an operational position.
  • the element shutter 204 is applied in this position with a upper peripheral edge 292, which is provided with a seal elastomer 294, against said second sealed surface 278 of the seat 202.

  • An inflatable elastomeric seal 298 is housed in a annular cavity 300, which is arranged in the surface lower device 296. In said position operational, this inflatable seal 298 faces said first sealing surface 276. When it is deflated, seal 298 is set back from the surface lower device 296 (see Figure 2). When he is swollen, i.e. pressurized by a fluid, the seal 298 is however firmly applied to said first sealing surface 276 and thus ensures the seal between the closure element 204 and the seat 202.
  • This channel supply 302 is preferably provided with supply lines outward and return connections, shown schematically by arrows 304 and 306. In this way we can organize a circulation of a liquid cooling through the inflatable seal 298. This liquid can also be identical to the liquid circulated at through the annular channel 282 of the seat.
  • annular channel 308 is arranged, which is connected by a passage 310 to a compressed air circuit or a pressurized gas.

  • the latter is interrupted by a vertical cylindrical surface 316, directly above said second sealing surface 278, which reduces wear of this surface.
  • the material retaining member 216, the adjusting member of the material flow 208 and the sealing member lower 200 are integrated all three in the hopper to material 18. This characteristic makes it possible to connect the lower outlet opening 48 of the hopper to material 18, directly to the loading nozzle 14, without passing an intermediate sealed chamber, of the type of chamber 58 in Figure 1. This results in a gain appreciable in mounting height.
