Problems solved by technology
The system described in the present application has the disadvantage that it is very difficult and time consuming to install on the chamber to be filled, thus undesirably increasing the downtime of the reactor
Moreover, this system comprising a telemetry device at the level of the filling device cannot operate with the thick loading device described in EP 0 769 462, since the presence of a rotating deflector between the filling front and the telemetry system will interfere with the laser telemetry

Embodiment Construction
[0055] figure 1 The apparatus in includes a funnel 1 containing the separated solids. This funnel 1 is fixed to the feed line 2 of the plant. During filling, the funnel 1 and the feed line 2 are filled with separated solids, from which the separated solids flow out through the orifice 7 on the side wall and / or bottom 5 of this feed line. These orifices 7 are preferably adjustable using adjustable closure means (not shown), such as variable orifice diaphragms, for adjusting the flow of separated solids into the chamber.
[0056] The feed line 2 is axially traversed along its entire length by a hollow central shaft 3 which is fastened by at least two bearings and which is flanked by drive means 4 which are preferably compressed air motors Drive rotation. The transmission between the motor 4 and the drive central shaft 3 takes place by any suitable means, for example by a belt. The entire filling device is securely held and fixed in the manhole (trou d'homme) of the reactor b...

The present invention relates to a device for equably loading a chamber with solid grain comprising a divided solid feeder hopper 1 and a spread system 8, which is connected to a central shaft 3 which rotates about a substantially vertical axis through a drive device 4, arranged on the bottom of the chamber to be loaded, and a feed pipeline 2 partially surrounding the central shaft. The device is characterized in that: the central shaft 3 is a pipe of large enough inner diameter and is used for implementing a plurality of correlative or auxiliary operations at the region to be loaded during the loading period, furthermore, a fixing pipe 6 connected with the feed pipeline 2 is arranged within the central shaft 3, and is substantially coaxial with the same.
Description
technical field [0001] The present invention relates to devices and methods for charging chambers with separated solids, in particular for charging chemical reactors with catalysts, and in particular for charging functional devices during the charging process by means of the hollow structure of the rotating shaft Introduced into and / or removed from the chamber. [0002] More particularly, the present invention relates to loading chemical or electrochemical, petroleum or petrochemical fixed bed reactors with solid particles in a separated state, the solid particles may be in the form of beads, granules, cylinders, pellets, rods, or any other shape, but they Usually of relatively small size. In particular, the particles may be molecular sieves or solid catalyst particles, generally extruded, prepared in irregular shapes or in the form of single or multiple rods, the size of which varies according to each individual case, from a few tens of millimeters to a few centimeters.
