Description
Technical field
The utility model is related to the fields such as blast furnace process, instrument and meter for automation, electrical, and in particular to a kind of blast furnace process is crucial
The monitoring device of data.
Background technology
Blast furnace is the closed reactor of a large-scale high temperature and pressure and dusty, and internal environment is extremely complex, blast furnace
Operating personnel are it should be understood that smelting process situation can not use intuitive detection means in stove.The monitoring of blast furnace level, usually
PLC controller is delivered to using mechanical stock rod gathered data, periodic measurement controlling level is capable of providing and gives blast furnace post personnel
Data it is limited, operating personnel can only rule of thumb judge the distribution situation of charge level, this is unfavorable for the Real-time Decision of execute-in-place.
In the blast furnace ironmaking process of constant pressure air feed, air port pressure detecting instrument detection data is delivered to PLC controller,
Blast furnace operating personnel by virtue of experience judge whether smelting process is different in stove by the monitoring of the data of blast-furnace tuyere wind pressure and air quantity
Often.In the blast furnace for determining wind pressure smelting, air port wind pressure should be constant, once wind pressure changes, necessarily occur in stove
Abnormal conditions, and post personnel must monitor wind pressure data the moment, wind pressure changes to be discovered in time, carry out rational reply
Strategy.It is all by virtue of experience to judge that operating personnel, which understand most of situation in stove, cannot be judged accurately very well.The prior art
It can not solve the above problems.
Utility model content
Purpose of the utility model is to solve operating personnel in the prior art according to the material position and wind pressure of blast furnace, air quantity
Monitoring data by virtue of experience judge situation in stove, cannot objective and accurate real-time progress decision the problem of, provide a kind of blast furnace
Smelt the monitoring device of critical data.
In order to achieve the above object, the utility model uses following technical scheme：
A kind of monitoring device of blast furnace process critical data, including be arranged in the stock rod of blast furnace internal upper part and setting in height
Draught temperature detector, air port flow detector, air port pressure detecting instrument on the air port of stove lower part, air port pressure detecting instrument it is defeated
Outlet, which is connected with pressure one and enters two, goes out signal isolator, and pressure one enters the output end that two go out signal isolator and is connected with PLC
Controller, pressure one enter another output end that two go out signal isolator and are connected with arithmetic unit, and the output end of arithmetic unit is connected with
Display screen；The output end of stock rod, which is connected with material position one and enters two, goes out signal isolator, and material position one enters two go out signal isolator one
Output end is connect with PLC controller, and material position one enters another output end that two go out signal isolator and connect with arithmetic unit.
The utility model compared with the existing technology, has the advantages that：
The monitoring device of the blast furnace process critical data of the utility model passes through the output end company in air port pressure detecting instrument
It connects pressure one and enters two and go out signal isolator, pressure one enters two output end connection PLC controllers for going out signal isolator, pressure
One enters two another output end connection arithmetic units for going out signal isolator, and the output end of arithmetic unit connects display screen；Stock rod it is defeated
Outlet connection material position one enters two and goes out signal isolator, and material position one enters two output ends and PLC controller for going out signal isolator
Connection, material position one enter another output end that two go out signal isolator and are connect with arithmetic unit.It more can directly calculate discharging
Position rate travel and wind pressure rate of change, can preferably assist blast furnace operator to make Real-time Decision, can be become by accumulation
Blast furnace process big data provides data supporting for preferably optimization blast furnace technology.

Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-2, a kind of monitoring device of blast furnace process critical data, including the spy in 1 internal upper part of blast furnace is set
Ruler 2 and the draught temperature detector 4 being arranged on 1 lower part air port 3 of blast furnace, air port flow detector 5, air port pressure detecting instrument
6, the output end of air port pressure detecting instrument 6, which is connected with pressure one and enters two, goes out signal isolator 7, and pressure one enters two and goes out signal isolator
7 output end is connected with the normal transmission that PLC controller 9 ensures blast furnace data, and pressure one enters two and goes out signal isolator 7
Another output end is connected with arithmetic unit 10, and the output end of arithmetic unit 10 is connected with LED display 11；The output end of stock rod 2 connects
It is connected to material position one and enters two and go out signal isolator 8, material position one enters two and goes out an output end of signal isolator 8 and PLC controller 9 connects
It connects, material position one enters another output end that two go out signal isolator 8 and connect with arithmetic unit 10.
When work, the wind pressure data detected from air port flow detector 5 input is passed through functional operation, meter by arithmetic unit 10
The wind pressure rate of change in the unit interval is calculated, and is shown on LED display 11；Arithmetic unit 10 will be nearest from stock rod 2
The difference of the data twice of detection is carried out according to time of measuring interval calculation discharging position rate travel on LED display 11
