Title
(EN) STEEL GRIT DRYER
(FR) SÉCHOIR À GRENAILLE D'ACIER
Abstract
(EN)
A mobile steel grit dryer used to dry steel grit may be configured with a number of different functions and features to assist a contractor in performing steel or other structure maintenance when using steel grit in resurfacing the structure. The steel grit dryer may be configured with a heat process vacuum bypass so that an off-board vacuum, such as a vacuum on a grit recycling system, may be utilized as opposed to having an onboard vacuum. The dryer may include multiple modes so that an operator may use different modes for different environmental conditions. An exoframe may provide for better durability when being transported to different jobsites. A variety of automation and safety features may also be provided to simplify and improve safety for operators.

Cette invention concerne un séchoir à grenaille d'acier mobile utilisé pour sécher de la grenaille d'acier, pouvant être configuré avec un certain nombre de fonctions et de caractéristiques différentes pour aider un entrepreneur à effectuer un entretien de structures d'acier ou autres lorsqu'il utilise de la grenaille d'acier pour le resurfaçage de la structure. Le séchoir à grenaille d'acier peut être configuré avec une dérivation de mise sous vide pour traitement thermique de telle sorte qu'un dispositif de mise sous vide externe, tel qu'un dispositif de mise sous vide sur un système de recyclage de grenaille, peut être utilisé par opposition à un dispositif de mise sous vide embarqué. Le séchoir peut comprendre de multiples modes de sorte qu'un opérateur puisse utiliser différents modes pour différentes conditions environnementales. Un cadre externe peut être fourni pour une meilleure durabilité lors du transport vers différents sites de travail. Diverses caractéristiques d'automatisation et de sécurité peuvent également être fournies pour simplifier et améliorer la sécurité des opérateurs.
