Abstract
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.
Claims8
A steel grit processing system, comprising:
- a steel grit dryer in fluid communication with a vacuum of a steel grit blast machine via a conduit within which a vacuum pressure is applied by the vacuum, the steel grit dryer including a heat bypass conduit that bypasses heat produced by a heat source on the steel grit dryer;
- and
- a hose in fluid communication with the heat bypass conduit, thereby enabling an operator to vacuum steel grit via the hose into the steel grit dryer to dry the steel grit using the vacuum pressure produced by the vacuum.
A steel grit dryer, comprising:
- a heat source configured to heat air in which steel grit is to be dried;
- a first conduit connector to which a conduit that is in fluid communication with a vacuum connects;
- a heat process bypass conduit in fluid communication with the first conduit connector, and arranged to bypass heat produced by the heat source;
- and
- a second conduit connector in fluid communication with the heat bypass conduit, and configured to enable a vacuum hose used to vacuum steel grit for drying by the steel grit dryer to be connected to and enable an operator to use the vacuum hose to vacuum steel grit into the steel grit dryer to be dried by the air heated by the heat source.
