Problems solved by technology

[0008] One problem is that, depending on the particle size, some concentric tubes can clog during filling because the tubes are not open enough, resulting in a suboptimal filling achieved and control of the filling parameters is tricky

Embodiment Construction

[0037] exist figure 1An apparatus 10 for filling a container (not shown) with solid particles is shown, the apparatus 10 comprising a reservoir 12 which receives solid particles in bulk. In this example, the particles are catalyst pellets for petrochemical reactors. It is to be noted that the diameter of the container to be filled with solid particles may be relatively large compared to the diameter of the device. Thus, the diameter of the container to be filled can vary between 0.5 and 15 meters, while the external diameter of the device can be comprised between 0.1 and 2.5 meters.

[0038] In the embodiment shown here, the reservoir 12 includes a brushed deflector 14 which allows distribution by deflecting the flow and causing the solid particles to mix with each other before they are dispensed into the container. Solid particles. In fact, the flow of solid particles in the reservoir tends to cause separation of the particles: longer particles tend to flow towards the out...

Abstract

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.

Description

technical field [0001] The present invention relates to the field of filling containers with solid particles such as grain or pellets. The container may for example be a reactor in the petroleum or chemical industry, or a silo for storing grain, feed or any other product in the form of solid particles. Background technique [0002] Filling of such containers is achieved by pouring solid particles from a funnel screen or funnel which pours the particles into the container by means of a flexible sleeve or rigid tube. [0003] Usually the aim is to fill the container with the maximum amount of solid product and to obtain as uniform a distribution of solid particles as possible in size, in order to get as close as possible to the theoretically determined optimal filling. [0004] In fact, especially in the case of chemical reactors, it is advantageous to have as large a mass of catalyst as possible in the reactor, in order to be able to lengthen the intervals between plant down...
