Abstract
A system for removing magnetic particles from a moving air stream. The system has magnetic collectors disposed in the air stream. The collectors may comprise mutually parallel motor driven rollers spaced which interact with the moving air stream. The rollers are optionally grooved or finned to provide for accumulation of collected particles. The rollers are in real time communication with a data hub. The data hub receives static and dynamic air handler performance parameters to monitor the performance parameters of the system which are indicative of and quantitatively relatable to debris accumulation on the rollers. When a threshold air handler performance parameter value is reached, the data hub alerts an operator for maintenance and restoration of the system.
Claims20
A system for removing magnetic particles from a moving air stream, said system comprising:
- an air handler having an inlet and an outlet for directing an air stream therethrough, the air stream having a plurality of magnetic particles entrained therein;
- at least one magnet disposed internal to said air handler so that said at least one magnet can interact with the air stream to remove magnetic particles therefrom;
- a motor operably associated with said at least said magnet to impart movement thereto during operation of said air handler;
- at least one air handler performance parameter sensor operably connected to each said at least one magnet, said sensor gathering data from air handler performance parameters selected from the group consisting of weight, current, voltage, torque and temperature and combinations thereof;
- and
- a data hub operably connected to each of said at least one air handler performance parameter sensor, the data hub being capable of determining an initial respective value of each said parameter and a respective change in said respective value of each said parameter responsive to and quantitatively indicative of accumulation of magnetic particles on that magnet and being capable of reporting a change in said respective value of each said at least one sensor to an operator.
A system for removing magnetic particles from a moving air stream, said system comprising:
- an air handler having an inlet and an outlet for directing an air stream therethrough, the air stream having a plurality of magnetic particles entrained therein;
- at least one motor driven, axially rotatable magnet disposed internal to said air handler so that said at least one magnet can interact with the air stream to remove magnetic particles therefrom;
- at least one air handler performance parameter sensor operably connected to each said at least one magnet, said sensor gathering data from air handler performance parameters selected from the group consisting of weight, current, voltage, torque, temperature and combinations thereof;
- and
- a data hub operably connected to each of said at least one air handler performance parameter sensor, the data hub being capable of determining an initial respective value of each said parameter and a respective change in said respective value of each said parameter responsive to accumulation of magnetic particles on that magnet and being capable of reporting a change in said respective value of each said at least one sensor to an operator.
A system for removing magnetic particles from a moving air stream, said system comprising:
- an air handler having an inlet and an outlet for directing an air stream therethrough, the air stream having a plurality of magnetic particles entrained therein;
- at least one motor driven, axially rotatable roller disposed internal to said air to interact with the air stream to remove magnetic particles therefrom, said roller having a core with a nonmagnetic shell;
- said shell having at least one of ports therethrough to expose a magnetic core and magnetic fins extending outwardly therefrom;
- at least one air handler performance parameter sensor operably connected to each said at least one magnet, said sensor gathering data from air handler performance parameters selected from the group consisting of weight, current, voltage, torque and temperature;
- and combinations thereof;
- and
- a data hub operably connected to each of said at least one air handler performance parameter sensor, the data hub being capable of determining an initial respective value of each said parameter and a respective change in said respective value of each said parameter responsive to accumulation of magnetic particles on that magnet and being capable of reporting a change in said respective value of each said at least one sensor to an operator.
