Abstract
The utility model which provides an automatic display alarm device relates to an automation device of the metallurgy industry, and the utility model which aims at the specific problems that the management intensity is high and the furnace age and production quality are influenced caused by the non-intellectualization of the working state display alarm method of the present blast furnace blowing coal powder branch pipe discloses an automatic display alarm device which comprises a typewriter, an industry control computer and a display screen, and the utility model comprises a data collecting unit, a signal isolating unit, a main control chamber wire connecting box, a field wire connecting box and a detected fluid physical transceiver unit, and the field signals and the detecting point physical signals are sent into the industry control computer through treatments of the data collecting unit and the signal isolating unit. Compared with the prior arts, the utility model which has the advantages of accurate calculation, quick reaction, clear display and timely forecast is specifically suitable for various kinds of industrial furnaces of the blowing coal powder.
Description
One, technical field
The utility model relates to the automatic displaying alarm of industrial furnace, particularly about detect a kind of automation equipment that pulverized coal injection in blast furnace arm duty centralized displaying is reported to the police with electric method methods such as (electric capacity, electric charge, electricity) leading.
Two, background technology
The device that shows pulverized coal injection in blast furnace arm duty at present adopts Thermal Meter to combine usually, feel in the practicality that lacking signal focuses on, picture shows that dynamic analysis is to functions such as coal injection arm duty diagnosis, have to go to handle, analyze, judge, report to the police by people's modus operandi, yet sometimes the delay time at stop, influence blast furnace and keep nominal situation, cause furnace life to descend, waste energy, product quality such as can not guarantee at serious consequence.
Three, summary of the invention
At above-mentioned weak point, the utility model will the applied electricity principle, can provide a kind of signal to focus on to many coal injection arms, the distribution state that shows each arm coal dust is calculated consumption coal total amount, and picture shows, the long distance transmission, dynamic analysis, record, and have a kind of automatic displaying alarm of analysis, diagnosis, warning function.In order to solve above-mentioned task, solution of the present utility model is: in displaying alarm, be provided with data acquisition unit, signal isolated location, master-control room terminal box, field terminal box, detected fluid physical signalling Transmit-Receive Unit.The master-control room terminal box, data acquisition unit receives line, data acquisition unit and output line thereof are connected successively with industrial control computer, show that on-the-spot coal injection arm normally jets, stop up, pre-alarm, sky blows, the blow off duty, measured tube physical signalling pipeline and the field terminal box and the output line thereof of the temperature signal that transmission detected fluid physical signalling Transmit-Receive Unit sends, concentration signal, rate signal, the master-control room terminal box, the signal isolated location receives line, the signal isolated location, signal isolated location output line is connected successively with industrial control computer; This computer also is connected to display screen, print signal line and printer.
Owing to be provided with data acquisition unit, signal isolated location, terminal box, detected fluid physical signalling Transmit-Receive Unit in the device of the present utility model, therefore having signal compared to existing technology focuses on, picture shows, the long distance transmission, dynamic analysis, record is analyzed accurately, diagnoses clear, the advantage of the sensitivity of reporting to the police, use on for the many blast furnaces of pulverized coal injection in blast furnace arm, can also reduce cost, it is timely to transfer manpower, handling failure is accurate, improve furnace life, good product quality, the advantage of increase economic benefit.
Four, description of drawings
Fig. 1 is automatic displaying alarm block diagram.
Among the figure, 1 printer, 2 print signal lines, 3 industrial control computers, 4 display screens, 5 data acquisition unit output lines, 6 signal isolated location output lines, 7 data acquisition units, 8 signal isolated locations, 9 data acquisition units receive line, and 10 signal isolated locations receive line, 11 master-control room terminal boxes, 12 field terminal box output lines, 13 field terminal boxs, 14 measuring point physical signal lines, 15 detected fluid physical signalling Transmit-Receive Units.
Five, the specific embodiment
It contains printer (1) the utility model, print signal line (2), industrial control computer (3) and display screen (4), also be provided with data acquisition unit (7) in the device, signal isolated location (8), master-control room terminal box (11), field terminal box (13), detected fluid physical signalling Transmit-Receive Unit (15).Master-control room terminal box (11), data acquisition unit receives line (9), data acquisition unit (7), data acquisition unit output line (5) is connected successively with industrial control computer (3), show that on-the-spot coal injection arm normally jets, stop up, pre-alarm, sky blows, and the blow off duty is transmitted the temperature signal that detected fluid physical signalling Transmit-Receive Unit (15) sends, concentration signal, the measured tube physical signalling pipeline (14) of rate signal, field terminal box (13), field terminal box output line (12), master-control room terminal box (11), the signal isolated location receives line (10), signal isolated location (8), and signal isolated location output line (6) is connected successively with industrial control computer (3).
Claims (1)
1, a kind of automatic displaying alarm that contains typewriter, industrial control computer, display screen, it is characterized in that being provided with data acquisition unit in this device, the signal isolated location, the master-control room terminal box, field terminal box, detected fluid physical signalling Transmit-Receive Unit, the master-control room terminal box, data acquisition unit receives line, data acquisition unit, and the data acquisition unit output line is connected successively with industrial control computer; Show that on-the-spot coal injection arm is normally jetted, obstruction, pre-alarm, sky are blown, the stop-spraying duty, the measured tube physical signalling pipeline of the temperature signal that transmission detected fluid physical signalling Transmit-Receive Unit sends, concentration signal, rate signal, with field terminal box, the field terminal box output line, the master-control room terminal box, the signal isolated location receives line, the signal isolated location, and signal isolated location output line is connected successively with industrial control computer.
