摘要:
The invention relates to a light-weight device for loading solid particles into an enclosure including at least one pipe (18, 20) for the circulation of said solid particles and at least one movable element for controlling the fall velocity of the particles, which is designed to be slidably moved inside of said pipe (18, 20). The device further includes a plurality of identical guide plates (12a, 12b) connected to each other by attachment means. Said at least one pipe (18, 20) is made of a flexible material and each guide plate (12a, 12b) has at least one through opening for receiving and guiding said at least one pipe (18, 20) in a position in which the longitudinal axis of the pipe extends substantially perpendicular to the plane of each guide plate.

The invention concerns a device (11) for loading solid particles (4) into a chamber (8), comprising a sleeve (20) wherein the solid particles (4) can flow, generally from up downwards, said sleeve (20) including at least one pipe (2) with substantially vertical axis (X'X), preferably made from a rigid material. Said device is characterized in that the pipe (2) contains at least one means (3) for controlling the speed of the particles (4) falling in said pipe (2), and the sleeve (20) includes several single elements (20a, 20b, 20c) successively nested into one another. The invention also concerns a loading method using such a device (1).

The invention relates to a device for loading solid particles into a chamber, comprising: a means for supplying the solid particles to be distributed, which discharges said particles into a supply channel (1); a mobile assembly (2) disposed below the supply channel (1), including a central shaft (3) and deflector elements (5) which are rotationally fixed to the shaft, disposed around the shaft at multiple vertical stages (E1-E4) and hinged to same such that they can move upwards; and a supply channel (1) which at least partially surrounds the central shaft and comprises at least one solid-particle-discharge hole (4) disposed in a horizontal and/or side wall. The device is characterised in that the mobile assembly (2) is designed to allow the position of the deflector elements (5) on the central shaft (3) to be adjusted in order to vary the permeability thereof to solid particles.

The invention relates to a device for loading solid particles into an enclosure, including: a means for supplying solid particles to be dispensed, which can be arranged on the top part of the enclosure to be loaded and which pours the solid particles in a substantially vertical manner into a feeding pipe (1); a mobile device (2) disposed entirely or partially inside the enclosure and under the feeding pipe, including a central shaft (3) rotatably driven by a motor means (4) about a substantially vertical axis and deflector elements (6) having a substantially identical shape and being rotatably secured to the shaft (3), preferably arranged in line with one another at different heights about the shaft (3) and pivotably connected thereto so that they can be raised, for example by centrifugal force; and a feeding pipe (1) at least partially surrounding said central shaft (3) and comprising at least one opening (5) for discharging the solid particles, which opening is provided on the horizontal or side wall thereof. The invention is characterised in that the device includes at least one deflector element (7) disposed on the rotatably driven shaft (3), the width of said deflector element (7) close to the shaft (3) being less than that of the other deflector elements (6), in particular the width of the element close to the shaft is smaller than that of the other deflector elements. The invention also relates to a use of said device and to a loading method involving said device.
