Description

Technical Field

[0001] The utility model relates to the technical field of glass production, and in particular to a DCS-based feeder fault alarm device. Background Art

[0002] The glass kiln uses an inclined blanket feeder for feeding operations. During actual production operations, the shovel pull rod is subjected to high force, resulting in the breaking of the connecting rod. Most automation equipment on the market only provides motor operation fault monitoring, and does not monitor push rods and pull rods such as couplings. When the pull rod drives the shaft, the motor does not alarm, and there is no prompt on the upper computer HMI (Human Machine Interface) screen. By the time the operation and maintenance personnel discover the fault and shut down the machine for emergency repairs, it has already caused significant losses to production.

[0003] After searching, the applicant found that the Chinese patent document with publication number 219259833U disclosed a feeder abnormal exit alarm device and a feeder on June 27, 2023, including a first power supply, a limit switch, a relay, a second power supply and an alarm; the limit switch is arranged at the feeder exit position, and the touch rod of the limit switch is in contact with the feeder; the coils of the first power supply, the limit switch and the relay are connected in sequence to form a first circuit; the second power supply, the contacts of the relay and the alarm are connected in sequence to form a second circuit; this device also cannot solve the above technical problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to provide a DCS-based feeder fault alarm device that can detect the status of the feeder's pull rod transmission shaft in real time and alarm when the pull rod transmission shaft is broken. Utility Model Content
