Definitions
- the invention relates to the cleaning of silos used for the storage of industrial products such as, for example, sodium carbonate.
- It relates more particularly to a device for cleaning such a silo.
- Silos intended for the storage of industrial products must be cleaned periodically.
- certain industrial products in particular sodium carbonate powder, tend, under the effect of gravity forces, to clump together and form incrustations on the wall of the silo.
- these incrustations generally tend to amplify over time, so that they reduce, sometimes considerably, the useful capacity of the silos and risk, in the long run, of clogging the withdrawal chutes.
- a first method used to detach incrus ⁇ tions from the wall of a silo is to break them by means of a percussion tool operated manually. This method involves the presence of an operator inside the silo, which constitutes a danger and is generally prohibited by safety rules, in the case of large silos.
- a known device designed for this purpose, comprises a metal chassis movable inside the silo and carrying the cutter, the chassis being able to rotate 360 degrees on a circular raceway disposed above an opening.
- This known device has the advantage of being able to be operated from outside the silo. However, its handling is difficult, its productivity is low and the cutter may also damage the wall of the silo.
- the invention therefore relates to a device for cleaning the wall of a silo, comprising a compressed air gun which can be moved inside the silo, the barrel being for this purpose suspended on two cables which are fixed respectively on the side and other from its center of gravity and which are respectively connected to two winches, by taking support respectively on two pulleys secured to a chassis which is disposed inside the silo and which is fixed to a turntable, movable on a circular path above a silo opening.
- the compressed air gun is an apparatus well known in the art, which is designed to project, in a defined direction, a jet of compressed air.
- the flow rate of the compressed air jet, its temperature and its pressure can be adjusted at will, using a compressor, valves and a pressure reducer, depending on the size of the incrus ⁇ tations to be detached and the nature of these incrustations. In practice, it is possible, for example, to adjust the pressure of the compressed air between 0.4 and 1.5 MPa. Examples of compressed air guns usable in the device according to the invention are described in the above-mentioned AIRNESCO brochure and in document GB-A-686842 (AIRNESCO).
- the compressed air gun is suspended in the silo by two cables connected respectively to two separate winches.
- the two cables are fixed to the barrel, respectively on either side of the center of gravity of the barrel.
- the winches ensure a vertical movement of the barrel inside the silo.
- the winches being maneuverable separately, they also allow the barrel to rotate 180 degrees in the vertical plane.
- the chassis and the turntable have the function of orienting the barrel in the horizontal plane.
- the cables supporting the barrel are supported separately on two separate pulleys of the chassis, so that the movement of the plate on the circular path, generally horizontal, ensures a 360 degree rotation of the chassis and the barrel around an axis vertical.
- the winches and at least one of the pulleys are preferably arranged in the immediate vicinity of the vertical passing through the center of the above-mentioned circular path.
- one of the pulleys is mounted at one end of an arrow which is articulated to the chassis, at its other end.
- the articulation of the boom to the chassis is arranged so as to allow the boom to rotate about a horizontal axis, to move the barrel away from or closer to the wall of the silo.
- the winches can advantageously be arranged outside the silo and the cables then pass through a central opening of the turntable which, for this purpose, is annular.
- the compressed air gun comprises a stabilizing mass. Its function is to absorb, by inertia, the feedback of the jet of compressed air on the barrel, so as to reduce the amplitude of the oscillations of the barrel and to stabilize it in the silo.
- the compressed air cannon carries a television camera, connected to a receiver located outside the silo.
- the television camera is oriented towards the front of the barrel and it has the function of viewing the front of the incrustation subjected to the jet of compressed air. In this way it allows permanent visual monitoring of the silo wall, which greatly facilitates the operation of the winches and the chassis to modify the position and orientation of the barrel.
- the device according to the invention is applicable to the cleaning of all silos that have contained an industrial product, for example wheat, coal or ore silos. He finds a particular appli ⁇ cation for removing scale from the silos used to store powdered sodium carbonate.
- the figure partially shows, in vertical axial section, the upper zone of a silo whose side wall 1 is pierced with a manhole 2 at its upper part.
- An agglomerate 3 of a solid substance adheres to the wall 1.
- a device is introduced into the silo, through the manhole 2 the invention.
- This comprises a rotating annular plate 4 placed on a horizontal circular path 5 formed at the periphery of the manhole 2.
- the circular path 5 and the tray 4 are arranged to allow the tray to rotate 360 degrees on the circular path 5.
- the tray 4 carries a frame 6 of metal beams inside the silo.
- An arrow 7 is articulated to the chassis 6 on a ball joint 8, so that it can pivot in a vertical plane, around a horizontal axis.
- a pulley 9 is fixed to the free end of the arrow 7 and three coaxial and independent pulleys 10 are fixed to the chassis 6, under the central opening 24 of the annular plate 4.
- the pulleys 10 are positioned substantially on the passing vertical axis through the center of the circular path 5.
- the inclination of the arrow 7 is adjusted by means of a cable 18 which is connected, via one of the three pulleys 10 to a winch 19 located outside the silo, above the manhole 2.
- An arm 11 carrying a compressed air gun 12 and a balancing mass 13, is suspended in the silo, by two cables 14 and 15 which pass through the central opening 24 of the annular plate 4 and are respectively connected to two separate winches 16 and 17 located outside the silo, above the manhole 2, in the immediate vicinity of the vertical axis of the circular path 5.
- the cables 14 and 15 fixed respectively on either side of the center of gravity of the assembly consisting of the arm 11, of the barrel 12 and of the balancing mass 13. They respectively bear on two of the three pulleys 10, the cable 14 also taking support on the pulley 9.
- the barrel 12 carries a camera of television 20 oriented towards the front of the barrel.
- a flexible sheath 21 passing through the opening 24 of the plate 4 is fixed to the arm 11. It contains a conduit for supplying the barrel 12 with compressed air produced by a compressor not shown, located outside the silo.
- the flexible sheath 21 also contains a cable for connecting the camera 20 to a television receiver, not shown, located outside the silo
- the barrel 12 is first brought in front of a zone 22 of the agglomerate to be attacked.
- the plate 4 is properly oriented on the path 5 to bring the barrel into the vertical axial plane of the zone 22 and the winches 16, 17 and 19 are maneuvered to bring the barrel 12 to the level of the zone 22.
- the winches 16 and 17 it is in particular possible, by means of the winches 16 and 17, to orient the arm 11 so that it occupies a horizontal position (as shown in the figure), a position for which the barrel 12 is directed obliquely towards the bottom or a position for which the barrel is directed obliquely upwards. It is advantageous to be able to orient the barrel 12 obliquely to attack an oblique face of the agglomerate 3 or to clean an inclined face 23 of the wall.
- the camera 20 makes it possible to easily and precisely find the optimum position of the barrel 12.
- the barrel 12 When the barrel 12 has reached the appropriate position opposite the agglomerate 3, it is placed in communication with the compressor so as to project a jet of compressed air onto the zone 22 of the agglomerate 3.
- the camera 20 makes it possible to follow the action of the compressed air jet on the agglomerate. As pieces of the agglomerate 3 detach under the effect of the compressed air jet (which is sent by successive pulses), the position and orientation of the barrel 12 is modified by means of the platform 4 and winches 16, 17 and 19.
