Abstract

The invention relates to a system ( 1 ) for distributing solid particles in order to load an enclosure with solid particles, including: a device ( 30 ) for supporting a device ( 10 ) for loading solid particles, said supporting device being arranged such as to maintain the loading device in the enclosure, and a sensor-supporting device ( 40 ), said sensor ( 46 ) intended for collecting information on the loading of the enclosure, and in which the system for distributing solid particles is arranged such that the supporting device and the sensor-supporting device can be mounted on the device for loading solid particles, while being movable relative to said loading device.

First claim

The invention claimed is:

1. A solid particle distribution system for charging a chamber with solid particles comprising:
a retention device for a charging device for solid particles, this retention device being arranged so as to ensure the retention of the charging device in the chamber and
a sensor support device supporting a sensor, the sensor being intended to acquire information relating to the charging of the chamber,
and wherein
the solid particle distribution system is arranged so that the retention device and the sensor support device are mounted on the solid particle charging device and the retention device and the sensor support device are able to be moved relative to this charging device,
the sensor support device is able to have vertical movements, rotation movements and/or radial movements and the retention device is able to have vertical movements, rotation movements and/or radial movements.

2. The distribution system as claimed in claim 1 , further comprising:
a cylindrical support element which is fixedly joined to the charging device and which is arranged so as to support the retention device and the sensor support device so that the retention device and the sensor support device can slide along this support element.

3. The distribution system as claimed in claim 2 , wherein the support element comprises a circular ring.

4. The distribution system as claimed in claim 2 , further comprising
a fixing plate which is fixedly joined to the retention device and/or to the sensor support device and which is mounted so as to slide on the support element.

5. The distribution system as claimed in claim 2 , further comprising
means for locking the retention device and/or the sensor support device on the support element.

6. The distribution system as claimed in claim 1 , further comprising:
means for adjusting the height of the retention device with respect to the charging device.

7. The distribution system as claimed in claim 1 , wherein the sensor support device comprises a spacer element in order to radially offset the sensor relative to the charging device.

8. The distribution system as claimed in claim 7 , wherein
the spacer element comprises a drive chain, and
the sensor support device comprises an element for guiding the drive chain, the guiding element being arranged so as to guide the drive chain so that a portion of the drive chain at an output of the guiding element extends in a direction different from that of a portion of the drive chain at an input of the guiding element.

9. The distribution system as claimed in claim 8 , wherein
the guiding element defines a passage for receiving the drive chain, the passage forming an angle close to 90°.

10. A method for installing a solid particle distribution system in a chamber, the solid particle distribution system comprising a retention device for a charging device, which retention device is arranged to ensure the retention of the charging device in the chamber, and a sensor support device supporting a sensor, the sensor being intended to acquire information relating to the charging of the chamber, the method comprising:
a step of assembling the sensor support device and the retention device on the charging device, and
a step of adjustment during which the sensor support device and the retention device are moved relative to the charging device in order to be adapted to the environment inside the chamber and/or the diameter of a bed of solid particles which it is desirable to monitor,
wherein the sensor support device is able to have vertical movements, rotation movements and/or radial movements and the retention device is able to have vertical movements, rotation movements and/or radial movements.
