Description
Technical field
The utility model relates to a kind of blast furnace granulated slag measurement mechanism, specifically blast furnace granulated slag blowing type liquid level measurement mechanism.
Background technology
When blast furnace granulated slag is iron and steel enterprise's smelting pig iron, after ash in non-ferrous components in iron ore and coke, injection coal etc. fusings, the product of discharging from blast furnace, is that to take calcium silicate be the fused mass of leading with ca aluminosilicate, through the material of the cold granulating of shrend, be called for short grain slag, water-granulated slag etc.The generation of grain slag, along with the grade of pig iron smelting technology and iron ore is different and change, is generally 25% ~ 40% of pig iron output.Along with the fast development of Iron industry, ironmaking the improving constantly of output, the output of grain slag also increases substantially, therefore, understand and study performance and the feature of grain slag, exploitation and comprehensive utilization grain slag, to salvaging, develop a circular economy, build a resource-conserving society, be significant.And first process procedure---the granulating pit of piling up as grain slag, it is the inevitable requirement of comprehensive utilization blast furnace granulated slag that the liquid level of grasping in real time, exactly granulating pit changes, and is also the demand of blast furnace production technology.
It is the principle that adopts radar or microwave sounding that at present a lot of blast furnace granulated slag liquid levels detects, and by the electromagnetic wave of transmitting fixed wave length, detects electromagnetic wave and travels to and fro between radar and object time, by calculating, draws.Although radar or microwave are a kind of very advanced distance-finding methods, but also there is its limitation in application, especially for this class of grain slag, take molten state particle as main, to have mixed water solidliquid mixture matter, precision and the accuracy measured are had a greatly reduced quality, result of use at actual process scene is very undesirable, and last past contact will be by means of artificial auxiliary judgment.Thereby cannot raise the efficiency, reduce costs.
Summary of the invention
The utility model is intended to overcome the defect of prior art, provides a kind of blast furnace granulated slag blowing type liquid level measurement mechanism, continuously and stably Real-Time Monitoring.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A blast furnace granulated slag blowing type liquid level measurement mechanism, is characterized in that: it comprises that air-source, gas blow pipe, constant current mode air blowing controller, grain slag liquid level detect controller and pressure unit; On described gas blow pipe, be respectively equipped with air intake, gas outlet and measurement mouth, the air pressure of gas outlet and measurement mouth equates; Described air-source is communicated with the air source inlet of constant current mode air blowing controller, the source of the gas outlet of constant current mode air blowing controller is communicated with the air intake of gas blow pipe, the gas outlet of gas blow pipe is positioned at granulated slag groove bottom, and pressure unit detects controller with the measurement mouth of gas blow pipe with grain slag liquid level respectively and is connected.
Described blast furnace granulated slag blowing type liquid level measurement mechanism, is characterized in that: the inside that described grain slag liquid level detects controller adopts eight layers of pcb board.
Described blast furnace granulated slag blowing type liquid level measurement mechanism, is characterized in that: the working temperature that described grain slag liquid level detects controller is-40 ℃～+ 85 ℃ or-25 ℃～+ 85 ℃.
The beneficial effects of the utility model are: realized the intelligent of blast furnace granulated slag liquid level detection system and improved precision and stability, having had good antijamming capability, having realized the continuous measurement of accurate stable of blast furnace granulated slag liquid level.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1: a kind of blast furnace granulated slag blowing type liquid level measurement mechanism, it comprises that air-source 1, gas blow pipe 2, constant current mode air blowing controller 3, grain slag liquid level detect controller 4 and pressure unit 5; On described gas blow pipe, be respectively equipped with air intake 21, gas outlet 22 and measure mouth 23, the air pressure of gas outlet and measurement mouth equates; Described air-source is communicated with the air source inlet 31 of constant current mode air blowing controller, the source of the gas outlet 32 of constant current mode air blowing controller is communicated with the air intake of gas blow pipe, the gas outlet of gas blow pipe is positioned at granulated slag groove 6 bottoms, it is zero liquid level place, use air-source to blow continuously to gas blow pipe by constant current mode air blowing controller, prevent gas blow pipe can be not mixed whose molten Particle Blocking, guaranteed to detect continuously with stable; Adopt constant current mode air blowing controller as the flow setting device on air blowing pipeline, guaranteed to continue in granulated slag groove, to be blown into quantitative gas, avoided waiting because gas flow is unstable the fluctuation of the detection data that cause; Pressure unit detects controller with the measurement mouth of gas blow pipe with grain slag liquid level respectively and is connected; The upper end pressure of pressure transmitter measurement gas blow pipe, owing to measuring the air pressure of mouth and gas outlet, equate, and this air pressure is identical with the grain slag liquid level static pressure at place, gas outlet, so measure the air pressure of mouth by detection, just can measure grain slag liquid level.
The inside of described intelligent controller adopts eight layers of pcb board; Its working temperature is-40 ℃～+ 85 ℃ or-25 ℃～+ 85 ℃.
Claims (3)
1. a blast furnace granulated slag blowing type liquid level measurement mechanism, is characterized in that: it comprises that air-source, gas blow pipe, constant current mode air blowing controller, grain slag liquid level detect controller and pressure unit; On described gas blow pipe, be respectively equipped with air intake, gas outlet and measurement mouth, the air pressure of gas outlet and measurement mouth equates; Described air-source is communicated with the air source inlet of constant current mode air blowing controller, the source of the gas outlet of constant current mode air blowing controller is communicated with the air intake of gas blow pipe, the gas outlet of gas blow pipe is positioned at granulated slag groove bottom, and pressure unit detects controller with the measurement mouth of gas blow pipe with grain slag liquid level respectively and is connected.
