The invention relates to a device (1) for filling a vertical elongate container (2) with granules, the container comprising elements (10) for slowing the fall of the granules, which elements are intended to be distributed vertically inside the container by means of elements (6) that support these fall-slowing elements (10, 20, 30), these supporting elements (6) being fixed along a first support that extends vertically and that is called the first vertical support (4A), in which device (1) the supporting elements (6) are also fixed along a second support that extends vertically and that is called the second vertical support (4B). The invention may especially be used in chemistry to fill a tubular reactor with catalyst, especially for vapour reforming.
The invention relates to a device for filling a container with solid particles, the device having annular ducts for passing particles, which ducts are defined by a plurality of vertical nozzles arranged coaxially relative to one another, and a diaphragm arranged upstream from the annular ducts for regulating the flow rate of particles in the annular ducts, the diaphragm has a plurality of shutter flaps for shutting off the annular ducts, each flap shutting off an angular sector of a single annular duct and the diaphragm having control means for controlling movement of the shutter flaps that are configured to be capable of partially shutting off any one of duct independently of the other ducts. The invention also relates to a method of shutting off a filler device.
The invention relates to a device for filling a container with solid particles comprising annular ducts (20, 20', 20") for the passage of the particles, delimited by a plurality of vertical tubes (16) positioned coaxially with respect to one another, and a diaphragm (22), positioned upstream of the annular ducts (20, 20', 20"), for regulating the flow rate of the particles in the annular ducts, the diaphragm (22) comprising a plurality of shutters for closing off the annular ducts, each one closing off an angular sector of a single annular duct and comprising control means for moving the closure shutters, configured in order to be able to partially close off one duct independently of the other ducts. The invention also relates to a process for closing off a filling device.
