Abstract

The invention relates to a bucket elevator measuring and calculating device, which comprises a touch display screen, a PLC, speed measuring switches and a pulverized coal bucket elevator, wherein themeasuring and calculating switches comprise the first speed measuring switch and the second speed measuring switch, the first speed measuring switch and the second speed measuring switch are arrangedon the left side and the right side of the pulverized coal bucket elevator respectively, and the first speed measuring switch and the second speed measuring switch are both connected with the PLC. ThePLC is connected with the touch display screen through a signal line. The speed measuring switches are installed on the two sides of the bucket elevator to calculate whether a chain operates normallyor not, the whole process is reminded by the audible and visual alarm, signals are introduced into the touch display screen of the duty room of the hot blast stove to display the operation state in real time, and online monitoring of the bucket elevator is achieved. And normal operation of the bucket elevator without groove disengagement is monitored, normal operation of the pulverized coal supply hot-blast stove is guaranteed, and shutdown caused by influence on production heat supply requirements due to hearth temperature reduction or sudden coking caused by insufficient pulverized coal supply is prevented.

Description

technical field [0001] The invention belongs to the field of bucket elevators for hot blast stoves in the iron and steel industry, and in particular relates to a bucket elevator measuring and calculating device. Background technique [0002] The pulverized coal bucket elevator of the No. 3 furnace uses a chain hopper to lift pulverized coal. Personnel in the fully sealed state cannot observe it. There is no detection and slipping device. Unscheduled downtime due to production heating. Contents of the invention [0003] The purpose of the present invention is to provide a bucket elevator measuring and calculating device with real-time on-line monitoring and sound and light alarm throughout the process. [0004] The technical solution adopted by the present invention to solve the technical problem is: a bucket elevator measuring and calculating device, including a touch display screen, PLC, a speed measuring switch and a pulverized coal bucket elevator. The first switch an...
