Abstract

La présente invention concerne un dispositif de commande d’un dépoussiéreur à air comprimé dans lequel un moteur de soufflante peut se refroidir lui-même même si des installations cibles de dépoussiérage réitèrent des mises en service et des arrêts, ainsi qu’un procédé de commande du dépoussiéreur à air comprimé. Le dispositif de commande pour le dépoussiéreur à air comprimé commande les mises en service individuelles d’un dispositif d’air comprimé et d’un moteur de soufflante du dépoussiéreur à air comprimé sous forme d’ensemble, arrête le moteur en fonctionnement en réponse à un signal d’arrêt du fonctionnement des installations cibles de dépoussiérage, et puis entraîne le dispositif d’air comprimé exclusivement pendant une période prédéterminée. Une unité de commande des mises en service du dispositif d’air comprimé est équipée d’une minuterie de refroidissement pour régler la période de fonctionnement de moteur continue afin que le moteur se refroidisse par lui-même.
