Definitions
- the present invention relates to the field of filling containers with solid particles such as grains or granules.
- These containers can be, for example, reactors for the petroleum or chemical industry or silos for the storage of cereals, fertilizers or any other product in the form of solid particles.
- the filling of such containers is done by transferring the solid particles from hoppers or funnels, which pour the solid particles into the container through flexible sleeves or rigid pipes.
- it is sought to fill the container with the maximum amount of solid product and to have the most homogeneous distribution of solid particles possible in terms of particle size so as to come as close as possible to the optimum filling theoretically determined.
- the feeding devices used for grain grain silos are very varied.
- no particular standard is imposed as to the flow rate to be observed for these supply devices.
- homogeneous filling can be made difficult because of the variable flow rate of the feed device used, or of the variable flow rates of the feed devices used for the same silo which depends in particular on the arrival of the trucks bringing the grains of cereals.
- the invention aims to remedy these drawbacks by proposing a filling system for a container intended to store solid particles which is not or only slightly sensitive to variations in the flow rate of solid particles in order to maintain a minimum flow rate capable of guaranteeing the filling of the container by a homogeneous rain of solid particles.
- the invention relates to a filling system for a container intended for storing solid particles, the system being arranged to cooperate with a device for supplying solid particles and comprising a device for distributing the particles.
- solids comprising at least one separating element intended to receive and selectively distribute the solid particles towards a distribution device
- the element separator comprising a body for receiving solid particles, one end of which has an axial opening intended to feed the distribution device continuously
- the distribution device comprising at least one spreading element intended to fill the container with solid particles in a homogeneous and driven manner by a drive shaft passing through the axial opening
- the receiving body comprises a frustoconical part comprising the axial opening and flaring away from the axial opening, the frustoconical part being extended by a tubular part comprising at least one radial opening situated upstream of the axial opening and arranged to direct the solid particles without meeting those leaving the axial opening before arriving in the distribution device from a predetermined quantity of solid particles stored in the frustocon
- the system therefore comprises a receiving body capable of maintaining a minimum flow rate even in the event of variations in flow rate of the device for supplying solid particles.
- the lower axial opening is preferably dimensioned with respect to the lowest flow rate which can be encountered and supplied by a buffer volume upstream in order to guarantee a substantially constant flow rate capable of filling the container with a homogeneous rain of solid particles.
- each upper radial opening is advantageously used to guarantee a minimum filling of the buffer volume upstream of the lower axial opening and to compensate for any variations in flow rate by directing the solid particles also towards the distribution device when the volume buffer upstream of the lower axial opening is filled. It is therefore understood that whatever the flow of solid particles received in the filling system, the latter will always be able to fill the container with a homogeneous rain of solid particles.
- the invention may also include one or more of the following optional features, taken alone or in combination.
- the axial opening can be delimited by a contour of substantially circular or polygonal shape which allows the solid particles to be easily directed towards the distribution device.
- the radial opening may be of shape delimited by a contour coinciding with the intersection of a cylinder (for example of circular or polygonal section) and a surface of the receiving element in order to easily direct the solid particles towards the distribution device, or have a shape which widens away from the axial opening in order to offer a variable distribution flow rate as a function of the storage height of the solid particles in the receiving body.
- the axial opening and / or the radial opening can be at least partially concealable in order to control the flow of solid particles feeding the dispensing device. Indeed, the selective concealment of the axial opening and / or of the radial opening can allow the filling system to be adaptable to the variations in flow rate of the same type of solid particles and / or to the similar or identical flow rate. different types of solid particles (for example if the same silo is used at different times to store different grains).
- the receiving body can be rotatably mounted to optimize the storage and distribution of solid particles.
- the feeding device is a belt conveyor
- the latter generates an inclined jet at the outlet of the belt which may not be oriented in the axial (vertical) direction when it arrives in the filling system.
- the rotation of the receiving body therefore makes it possible to compensate for this asymmetry by filling the buffer volume of the receiving body more homogeneously.
- its movement promotes settlement in its buffer volume.
- the movement of the receiving body makes it possible to optimize the distribution of solid particles between the axial and radial openings.
- its movement promotes the passage of solid particles through the axial opening when its buffer volume is filled.
- its displacement makes it possible to distribute angularly a possible defect of passage, like a stuck object, at the level of the axial and radial openings in order to make more homogeneous the flow of solid particles feeding the distribution device.
- the receiving body can be linked to a drive mechanism, such as electric, in order to be selectively moved. This allows in particular to be able to control the movement (start, speed, stop, etc.) according to the operating conditions of the filling system.
- a drive mechanism such as electric
- the drive mechanism can be coupled to the distribution device in order to make proportional the movement of the receiving element relative to that of the scattering element which allows, for example, d '' use the motor of the distribution device to move the receiving element or vice versa.
- the receiving body can also include at least one drive element intended to cooperate with the flow of solid particles to move the receiving body. This allows in particular to be able to absorb a part of the energy of the displacement of the solid particles so as not to have to add a drive mechanism.
- the scattering element may include a turntable provided with fins of varying lengths so that the periphery of the tray extends in substantially at least one spiral so as to fill the container in the form of a homogeneous rain of solid particles.
- the separator element may further comprise a fixed casing surrounding the receiving body in order to guide the solid particles leaving the radial opening towards the distribution device.
- Figure 1 is a perspective view of a filling system according to the invention.
- Figure 2 is a perspective view similar to Figure 1 in which a portion of the housing has been removed in order to view a receiving body of the filling system according to the invention;
- Figure 3 is a perspective view of the receiving body.
- orientations are the orientations of the figures.
- the terms “upper”, “lower”, “left”, “right”, “above”, “below”, “forward” and “backward” are generally understood with respect to the direction of representation of the figures.
- the invention generally relates to a filling system for a container such as a catalysis reactor or a storage silo intended to store solid particles such as catalyst in the form of granules or cereal grains.
- the filling system is intended to be mounted in the upper part of the container in order to distribute, according to a uniform and regular rain, the solid particles making it possible to fill the container progressively along an upper front forming a substantially flat and horizontal surface.
- This type of filling makes it possible to maximize the quantity of solid particles stored in the container according to a very homogeneous distribution but also to ensure the protection of solid particles in particular by avoiding their attrition generating dust.
- the filling system 1 is arranged to fill a silo with cereal grains.
- the invention can also be applied to other fields such as catalysts for the petroleum industry or more generally for the chemical industry.
- the filling system 1 is arranged to cooperate with a feed device (not shown) of solid particles.
- the feeders are generally belt conveyors that discharge the grain into a filling nozzle mounted on the roof of the silo.
- the filling system 1 according to the invention is therefore placed at the outlet of this filling nozzle to distribute the cereal grains uniformly in the silo.
- the filling system 1 comprises a fixing device 3, a distribution device 5 and a device 7 for distributing solid particles.
- the fixing device 3 mainly comprises a chassis 4 intended to support the filling system 1 in the silo and to be fixed to at least one wall of the silo and / or the filling nozzle of the silo.
- the distribution device 5 is intended to receive and selectively distribute the solid particles coming from the filling nozzle of the silo towards the distribution device 7.
- the device 5 mainly comprises a hopper 8 extended by at least one separating element 9.
- the hopper 8 forms a funnel intended to channel the cereal grains from the filling nozzle of the silo towards the separating element 9.
- the hopper 8 is not an essential element of the invention. Thus, it could be removed or replaced by another type of delivery device.
- the separator element 9 advantageously comprises according to the invention a body 11 for receiving solid particles intended to guarantee a minimum flow of solid particles even in the event of variations in the flow rate of the solid particle feed device.
- the receiver body 11 has a frustoconical part 11 a and a tubular part 11 b formed integrally.
- the lower end of the frustoconical part 11 has an axial opening 13, the frustoconical part 11 flares away from the axial opening 13.
- the frustoconical part 11 therefore makes it possible, by gravity, to direct the particles solid towards the axial opening 13.
- the frustoconical part 11 a is extended by the tubular part 11 b comprising at least one radial opening (four in FIGS. 2 and 3).
- the axial orientation in the position of use of the filling system 1 corresponds substantially to that of the action of gravity.
- Each radial opening 15 is advantageously formed without the need to move parts or occluders.
- the axial opening 13 is intended to continuously supply the device 7 for dispensing solid particles while each opening 15 radial, located upstream of the axial opening 13, is arranged to direct the solid particles to the dispensing device 7 beyond a predetermined amount of solid particles stored in the receiving body 11.
- the two parts 11 a, 11 b of the latter allow the solid particles leaving each radial opening 15 not to meet those leaving the axial opening 13 before arriving in the dispensing device 7.
- the axial opening 13 can be of various shapes.
- the axial opening 13 can be delimited by a contour of substantially circular or polygonal shape in order to easily direct the solid particles towards the device 7 for distribution.
- the axial opening 13 is delimited by a circular contour.
- the solid particles pass through an annular space formed by the axial opening 13 delimited by a contour of circular shape at the center of which a drive shaft of the distribution device 7 is present.
- other forms of axial opening 13 can be envisaged without departing from the scope of the invention.
- each radial opening 15 is at least equal to one and cannot be limited to four as illustrated in FIGS. 2 and 3.
- each radial opening 15 can also be of various shapes.
- each radial opening 15 can thus be delimited by a contour coinciding with the intersection of a cylinder and a surface of the receiving element in order to easily direct the solid particles towards the distribution device 7.
- the section of the cylinder can thus be substantially circular or polygonal.
- at least one radial opening 15 may have a shape which flares away from the axial opening 13 as illustrated in FIGS. 2 and 3. This shape in fact makes it possible to offer a variable distribution rate depending on of the height of storage of solid particles in the receiving body 11.
- other forms of radial opening 15 can be envisaged without departing from the scope of the invention.
- the filling system 1 therefore comprises a receiving body 11 capable of maintaining a minimum flow even in the event of variations in flow of the feed device (not shown) in solid particles. More specifically, the lower axial opening 13 is preferably dimensioned with respect to the lowest flow rate which can be encountered and supplied by a buffer volume (volume of solid particles stored in the receiving body 11) upstream in order to guarantee a substantially constant flow. able to permanently fill the container with a homogeneous rain of solid particles.
- each upper radial opening 15 is advantageously used to guarantee a minimum filling of the buffer volume upstream of the lower axial opening 13.
- Each upper radial opening 15 also makes it possible to compensate for any variations in the flow rate of the supply device (not shown) by directing, if necessary, the solid particles also towards the distribution device 7 when the buffer volume upstream of the lower axial opening 13 is filled. It is therefore understood that whatever the flow of solid particles received in the filling system, the latter will always be able to supply the dispensing device 7 so that it fills the container with a homogeneous rain of solid particles.
- the receiver body 11 is mounted to rotate in order to optimize the storage and distribution of solid particles.
- the feeding device is a belt conveyor
- the latter generates an inclined jet at the outlet of the belt which may not be oriented in the axial (vertical) direction when it arrives in the filling system.
- the rotation of the receiving body therefore makes it possible to compensate for this asymmetry by filling the buffer volume of the receiving body more homogeneously.
- its movement promotes settlement in its buffer volume (volume of solid particles stored in the receiver body 11 upstream of the axial opening 13).
- the movement of the receiving body 11 makes it possible to optimize the distribution of solid particles between the axial and radial openings 13, 15.
- the receiver body 11 can be linked to a drive mechanism 17 in order to be selectively moved. This allows in particular to be able to control the movement (start, speed, stop, etc.) according to the operating conditions of the filling system.
- Different types of drive mechanism 17 can be envisaged, for example hydraulic, pneumatic or electric.
- the drive mechanism 17 mainly comprises a toothed wheel 18 secured to the tubular part 11b of the receiver body 11, a reduction train 19 and a motor assembly 20. Therefore, it is understood that the rotation of the receiver body 11 can be actuated without the mandatory presence of an operator.
- the activation of the rotation of the receiving body 11 could be subject to the activation of the feeding device (not shown) or the presence of solid particles in the receiving body 11.
- the receiver body 11 may also include at least one drive element (not shown) intended to cooperate with the flow of the particles solid to move the receiver body 11.
- the drive element could be formed by a curved or straight rib mounted on the internal wall of the receiving body 11 so that the abutment of part of the axial movement of the solid particles against these ribs induces a rotation of the receiving body 11. It is therefore understood that the rotation of the receiving body 11 would be dependent on the flow of solid particles arriving in the receiving body 11.
- the receiver body 11 can also be coupled to the distribution device 7 in order to make the movement of the receiver body 11 relative to that of the scattering element 21 which allows , for example, using the motor of the dispensing device 7 to move the receiving body 11 or vice versa.
- a toothed wheel secured to the tubular part 11b of the receiver body 11 could be coupled by a reduction gear (for example a planetary gear train) to the motor of the distribution device 7 or to a drive shaft of the motor. such as, for example, that of the scattering element 21.
- the receiving body 11 could rotate between two and eight times slower than the plate 23, as, for example, four times slower. However, nothing prevents conversely that the receiving body 11 rotates at the same speed or faster than the scattering element 21.
- the separator element 9 may also include a fixed casing 10 surrounding the receiver body 11 in order to guide the solid particles leaving each radial opening 15 towards the distribution device 7.
- the distribution device 7 can be of different types. It comprises at least one scattering element 21 driven by a motor shaft connected to a motor (not visible) and intended to fill the container with solid particles in a homogeneous manner and, preferably, in the form of a homogeneous rain of solid particles.
- the scattering element 21 may comprise, as illustrated in FIGS. 1 and 2, a turntable 23 provided with fins 22 making it possible to eject, by centrifugal force, the solid particles in a homogeneous distribution. As can be seen in FIGS.
- the fins 22 preferably have variable lengths so that the periphery of the plate 23 extends in the form of a substantially spiral or several spirals so as to eject the solid particles according to several rays capable of creating the distribution in the form of homogeneous rain.
- dispensing devices 7 can be used, such as the strap type or the whip type.
- the invention is not limited to the embodiments and variants presented and other embodiments and variants will be apparent to those skilled in the art.
- radial openings 15 are present on the frustoconical part 11 a.
- one or more of the axial and radial openings 13, 15 may be partially or completely concealable, for example, using a diaphragm, or a flap, selectively movable in order to adjust the free passage section of the axial and radial openings 13, 15.
- selective occultation would make it possible to adapt to the flow rate of the same type of solid particles or to adapt to the flow rate of different types of solid particles (for example in the case where the same silo is used at times to store different cereals).
- the filling system 1 comprises a body 11 receiving geometries and different dimensions without departing from the scope of the invention.
- the filling system 1 can also include several receiving bodies 11 of identical shape or not mounted coaxially in order to optimize the distribution of solid particles.
- the filling system 1 comprises several distribution devices 7 of identical geometry or not mounted coaxially in order to optimize the distribution of solid particles.
- several scattering elements 21 could thus each comprise, as illustrated in FIG. 1, a turntable 23 provided with fins 22 allowing the ejections, by centrifugal force, of the solid particles in a homogeneous distribution.
