WIRELESS TEMPERATURE SENSING AND CONTROL SYSTEM FOR METAL KILN AND METHOD OF USING THE SAME

摘要

A rotary aluminum kiln temperature regulation system (10) comprising one or more temperature sensing and transmitting devices (14, 16, 18, 20) in the kiln that is configured to take temperature readings in an area of the kiln in proximity to the one or more temperature sensing and transmitting devices (14, 16, 18, 20) and wirelessly transmit those readings to a receiver (22). The system (10) also includes a control unit (24) operatively connected to the receiver (22) that is configured to receive the transmitted temperature readings and determine when the transmitted temperature readings exceed a predefined temperature setpoint. The control unit (24) is operatively connected to one or more heat flow control devices (13, 15, 31, 34, 37, 40, 41, 110, 116, 122, 124) that can adjust heat flow inside the kiln in proximity to the one or more temperature sensing and transmitting devices (14, 16, 18, 20), such that the control unit (24) regulates the one or more heat flow control devices (13, 15, 31, 34, 37, 40, 41, 110, 116, 122, 124) to maintain a desired level of heat flow in the kiln (12) in proximity to the one or more temperature sensing and transmitting devices (14, 16, 18, 20) in response to the temperature readings transmitted from the one or more temperature sensing and transmitting devices (14, 16, 18, 20).
