Embodiment
, for ease of implementation method of the present invention and the effect that reaches are had further understanding, now coordinate the accompanying drawing preferred embodiment that develops simultaneously to be described in detail as follows.
Be divided into material feeding jar (being subjected to batch can) and blanking tank (gravimetric tank) without bell string pan furnace top.Under groove, system is transported to material feeding jar with furnace charge by main belt, when blanking tank meets the charging condition, the upper lock gate in material feeding jar is opened, and furnace charge is from the material feeding jar blanking tank of packing into.This moment, furnace charge was waited for stockline in blanking tank, in the process of waiting for, need to carry out punching press to blanking tank, after arriving stockline, tail gates in blanking tank are opened, and furnace charge was shed in blast furnace by distributing device according to the angle that has set and time, had so just completed the cloth process one time.In this process, respectively material feeding jar and blanking tank are set up one or more software track devices, i.e. material feeding jar software track device and blanking tank software track device, to charging, discharge, the punching press of furnace roof, the states such as pressure release are followed the tracks of.
When system under groove during to the blast furnace roof discharge, under groove, system can autofeed be criticized and generates software track device under a groove, and this tracker is generated by system software under groove, can the current position of real-time follow-up charge.After charge arrived furnace roof, furnace top system can be received under groove the stub bar arriving signal that system sends over, and at this moment furnace top system just can start material feeding jar software track device.
Software track device in the present invention includes time detecting module, parameter setting module, time comparison module, alarm module and equipment optimization module.this time detecting module is for detection of the time span of the start-stop moment of pushing up each technological process without bell string pan furnace with definite each technological process, set the reference time of each technological process according to parameter setting module, compare with the reference time that sets by the real time length of time comparison module to each technological process, when the time span of technological process reality surpasses the reference time that sets, alarm module sends alerting signal, starting outfit optimization module is optimized equipment in order to the time span of each technological process was controlled in the reference time of setting simultaneously, improve whereby charging and discharge efficiency without bell string pan furnace top.
As shown in Figure 1, the time detecting module by material feeding jar software track device detects respectively: 1 moment for charge arrival furnace roof; 2 is the moment that charge enters furnace roof fully; 3 moment that start to open for upper lock gate; 4 moment of for upper lock gate, opening fully; 5 for starting to close the moment of material loading lock; 6 close fully for the material loading lock, finish the moment of material feeding jar tracker.
Can clearly recognize the situation of this batch of material at material feeding jar from material feeding jar software track device, comprise following 5 time periods:
Tsl enters the time span of material feeding jar for this batch of material, the length of this time depends primarily on the aperture of system gate under groove, the mode of discharge and the width of belt;
The time span that Tsw deposits in material feeding jar for this batch of material, when blanking tank does not also possess the charging condition, the charge that under groove, system sends over will first be stored in material feeding jar, in case after blanking tank possessed the charging condition, charge will be transferred to blanking tank by material feeding jar;

Tsc is the time span of closing upper lock gate, and the length of this time depends primarily on the working condition of pressure and the valve arrangement of hydraulic system;
Material feeding jar software track device will carry out record to these times respectively, the clear and definite present residing state of charge that demonstrates after starting.The time period of each technological process can be set a reference time by parameter setting module according to knowhow equally, start-up time comparison module, when in case time period length surpasses the reference time of setting, start the alarm module of material feeding jar software track device, system provides warning automatically on picture, prompting charging process existing problems.Such as, set a time ts to Tsz, but the actual time to the blanking tank charging is greater than ts, illustrate in this process and have problems, be likely that upper lock gate has got stuck, at this moment system just can be reported to the police, and starts the equipment optimization module of material feeding jar software track device this moment upper lock gate is handled it.
Can also find out from the material feeding jar tracker, when Tsw=0, this moment, program process just can be optimized for as shown in Figure 2.In the material feeding jar charging, consider the opening time of upper lock gate, at this moment can open in advance upper lock gate, so just reduced the charge time of furnace top system.
After upper lock gate cut out fully, at this moment furnace top system just can start blanking tank software track device.
As shown in Figure 3, the time detecting module by blanking tank software track device detects respectively: the 1 ' moment of for upper lock gate, closing fully; 2 ' is the complete moment of blanking tank punching press; 3 ' is the moment of stock rod to stockline; 4 ' the moment that starts to open for tail gates; 5 ' the moment of for tail gates, opening fully; 6 ' the moment that starts to close for tail gates; 7 ' the moment of for tail gates, closing fully; 8 ' is the complete moment of blanking tank pressure release.
Txp is the punching press time span of this batch of material, and the length of this time depends primarily on the impact style of furnace top system employing and the size of punching press gaseous tension;
The time span that Txw deposits in blanking tank for this batch of material, the length of this time depends primarily on the working of a furnace of blast furnace system;
Txt is the time span that stock rod is carried chi, and the length of this time depends primarily on the setting of stockline and puies forward the speed of chi;
Txo is for opening the time span of tail gates, and the length of this time depends primarily on the working condition of pressure and the valve arrangement of hydraulic system;
Txb is the cloth time span of this batch of material, and the length of this time depends primarily on the burden distribution matrix setting means of this batch of material;
Txc is the time span of closing tail gates, and the length of this time depends primarily on the working condition of pressure and the valve arrangement of hydraulic system;
Txf is the time span of pressure release, and the length of this time depends primarily on the size of furnace top pressure.
Blanking tank software track device will carry out record to these times respectively, the clear and definite present residing state of charge that demonstrates after starting.The time period of same each process can be set a reference time by parameter setting module according to knowhow, when in case time period length surpasses the reference time of setting, start the alarm module of blanking tank software track device, system provides warning automatically on picture, prompting charging or cloth process existing problems, start the equipment optimization module of blanking tank software track device relevant device is handled it this moment.
By the foundation without bell string tank furnace top charging material software tracker, can very clearly understand the concrete condition of charge, in time provide alarm condition, optimize action sequence.Material feeding jar can match with software track device under groove with the software track device of blanking tank, so just can reduce main belt stopping time, and very fast material loading rhythm, improve charging capacity.
The above, be only preferred embodiment of the present invention, not is used for limiting protection scope of the present invention.
