Abstract
Description
La présente invention concerne un système de décolmatage pneumatiqueThe present invention relates to a pneumatic declogging system
industriel pour permettre l'écoulement mécanique de matières stockées colmatantes et pulvérulentes dans des silos et trémies, et qui ne s'évacuent pas de manière naturelle. industrial to allow the mechanical flow of clogging and powdery storage materials in silos and hoppers, and which do not drain naturally.
La technique habituellement utilisée est le ringardage manuel, soit à l'aide de marteaux frappant l'enveloppe métallique de l'unité de stockage, soit à l'aide de pics ou lances à air plantés dans la matière stockée qui ne s'écoule pas. The technique usually used is the manual interlocking, either with hammers striking the metal casing of the storage unit, or with the help of picks or air lances planted in the stored material that does not flow. .
Le risque d'accident pour les opérateurs est réel, et difficile à anticiper en cas d'éboulement brutal de la matière.De plus, l'environnement poussiéreux et les conditions de température parfois élevées rendent ce travail ingrat. The risk of accidents for operators is real, and difficult to anticipate in the event of a sudden collapse of the material. Moreover, the dusty environment and the sometimes high temperature conditions make this work ungrateful.
Le dispositif selon l'invention permet de remédier a ces dangers. Il permet en effet de prévenir ces risques en mécanisant le ringardage et de ce fait protége l'opérateur qui déclenche l'écoulement de la matière à distance. The device according to the invention makes it possible to remedy these dangers. It allows to prevent these risks by mechanizing the ringardage and thus protects the operator who triggers the flow of the material at a distance.
L'action de l'air comprimé permet de créer une déflagration pneumatique dont la force d'impact est suffisante pour forcer l'écoulement de la matière stockée. The action of the compressed air creates a pneumatic deflagration whose impact force is sufficient to force the flow of the stored material.
Les dessins annexés illustre l'invention La figure 1 représente en coupe le dispositif de l'invention en mode admission et remplissage. The accompanying drawings illustrate the invention. FIG. 1 represents in section the device of the invention in admission and filling mode.
La figure 2 représente en coupe le dispositif de l'invention en mode de tir En référence à ces dessins, le dispositif comporte une vanne 3 voies (6) munie de trois orifices: d'admission (A), de remplissage (B) et de tir (C). FIG. 2 represents in section the device of the invention in firing mode. With reference to these drawings, the device comprises a 3-way valve (6) provided with three orifices: intake (A), filling (B) and shooting (C).
L'admission (figure 1) L'air comprimé pénètre par le plateau de fermeture (1) dans la chambre arrière (A). Un piston circulaire (5) boulonné (3) sur un guide creux (4) obture l'orifice de la chambre de tir (C) grâce a un ressort (2) maintenant l'ensemble piston (5) et guide creux (4) en pression mécanique étanche sur ce même orifice. Inlet (Figure 1) Compressed air enters through the closure plate (1) into the rear chamber (A). A circular piston (5) bolted (3) on a hollow guide (4) closes the orifice of the firing chamber (C) through a spring (2) holding the piston assembly (5) and hollow guide (4) in mechanical pressure sealed on the same hole.
Le remplissage (figure 1) L'air comprimé fuit dans la chambre de remplissage (B) grâce à un faible jeu suffisant entre les parois latérales du plateau de fermeture (1) et du guide creux (4) pour permettre cette fuite laminaire. Filling (Figure 1) Compressed air leaks into the filling chamber (B) due to a small clearance between the side walls of the closure plate (1) and the hollow guide (4) to allow this laminar leakage.
Le tir (figure 2) La sortie brutale de l'air contenu dans la chambre d'admission (A) est déclenchée par la vidange instantanée de l'air contenu dans cette même chambre (A) et dans le guide creux (4).La dépression constatée dans la chambre d'admission (A) va plaquer l'ensemble piston (5) et guide creux (4) sur l'arrière du plateau de fermeture (1). Firing (Figure 2) The sudden exit of the air contained in the intake chamber (A) is triggered by the instantaneous emptying of the air contained in the same chamber (A) and in the hollow guide (4). The depression found in the intake chamber (A) will press the piston assembly (5) and hollow guide (4) on the rear of the closure plate (1).
L'étanchéité sur l'orifice de la chambre de tir (C) est brutalement rompue, et 10 l'air contenu dans la chambre de remplissage (B) est abruptement relâché dans la chambre de sortie....créant la déflagration requise pour l'évacuation de la matière stockée. The seal on the orifice of the firing chamber (C) is abruptly broken, and the air contained in the filler chamber (B) is abruptly released into the exit chamber .... creating the required deflagration to evacuation of the stored material.
A titre non limitatif, la vanne trois voies (4) a des dimensions différentes en fonction de la taille des trémies et silos ainsi que du degré de colmatage constaté de la matière. Non-limiting, the three-way valve (4) has different dimensions depending on the size of the hoppers and silos and the degree of clogging found the material.
Le dispositif selon l'invention est particulièrement destiné à l'évacuation de matières colmatantes dans des silos et trémies contenant de la matière 20 pulvérulente. The device according to the invention is particularly intended for the evacuation of clogging materials in silos and hoppers containing pulverulent material.
