Embodiment
For ease of implementation method of the present invention and the effect that reaches are had further understanding, the preferred embodiment that develops simultaneously of existing conjunction with figs. is described in detail as follows.
No bell string pan furnace top is divided into batch can (being subjected to batch can) and blanking tank (gravimetric tank).System is transported to batch can with furnace charge by main belt under the groove, when blanking tank satisfies the charging condition, the upper lock gate in the last batch can is opened, and furnace charge is gone into blanking tank from material loading is canned.This moment, furnace charge was waited for stockline in blanking tank, in the process of waiting for, need carry out punching press to blanking tank, after arriving stockline, tail gates in the blanking tank are opened, and furnace charge was shed in the blast furnace by distributing device according to angle that has configured and time, had so just finished the cloth process one time.In this process, respectively last batch can and blanking tank are set up one or more software track devices, promptly go up batch can software track device and blanking tank software track device, to charging, discharge, the punching press of furnace roof, states such as pressure release are followed the tracks of.
When system under the groove during to blast furnace furnace roof discharge, system can autofeed criticize and generates software track device under the groove under the groove, and this tracker is calculated by system software under the groove and generates, can the current position of real-time follow-up charge.After charge arrived furnace roof, furnace top system can be received the stub bar arriving signal that system sends under the groove, and at this moment furnace top system just can start upward batch can software track device.
Software track device among the present invention includes time detecting module, parameter setting module, time comparison module, alarm module and equipment optimization module.This time detecting module is used to detect no bell string pan furnace and pushes up the start-stop of each technological process constantly to determine the time span of 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 each technological process, when the time span of technological process reality surpasses the reference time that sets, alarm module sends alerting signal, the starting outfit optimal module is optimized equipment so that the time span of each technological process was controlled in the reference time of setting simultaneously, improves the charging and the discharge efficient on no bell string pan furnace top whereby.
As shown in Figure 1, the time detecting module by last batch can 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 begin to open for upper lock gate; 4 moment of opening fully for upper lock gate; 5 for beginning to close the moment of material loading lock; 6 close the moment of batch can tracker in the end fully for the material loading lock.
From last batch can software track device, can clearly recognize the situation of this batch of material, comprise following 5 time periods at last batch can:
The time span that Tsl enters batch can for this batch of material, the length of this time depend primarily on the aperture of system's gate under the groove, the mode of discharge and the width of belt;
The time span that Tsw deposits in last batch can for this batch of material, when blanking tank does not also possess the charging condition, the charge that system sends under the groove will be stored in the batch can earlier, in case after blanking tank possessed the charging condition, charge will be transferred to blanking tank by last batch can;
Tso is for opening the time span of upper lock gate, and the length of this time depends primarily on the working condition of the pressure and the valve arrangement of hydraulic system;
Tsz is the down time span of batch can charging of last batch can, and the length of this time depends on the bore of the kind of charge, weight and upper lock gate;
Tsc is the time span of closing upper lock gate, and the length of this time depends primarily on the working condition of the pressure and the valve arrangement of hydraulic system;
Last batch can software track device will carry out record to these several 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, the alarm module of batch can software track device in the startup, system provides warning automatically on picture, prompting charging process existing problems.Such as, set a time ts to Tsz, but the actual time of feeding to blanking tank is greater than ts, illustrate in this process and have problems, might be that upper lock gate has got stuck, at this moment system just can report to the police, and starts the equipment optimization module that goes up batch can software track device this moment upper lock gate is handled it.
Can also find out that from last batch can tracker when Tsw=0, this moment, program process just can be optimized for as shown in Figure 2.In the canned material of material loading, consider opening the time of upper lock gate, at this moment can open upper lock gate in advance, 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 closing fully for upper lock gate; 2 ' the moment that finishes for the blanking tank punching press; 3 ' is the moment of stock rod to stockline; 4 ' the moment that begins to open for tail gates; 5 ' the moment of opening fully for tail gates; 6 ' the moment that begins to close for tail gates; 7 ' the moment of closing fully for tail gates; 8 ' the moment that finishes for the 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 the 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 cloth 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 the 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 several 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 moments.
By the foundation of no bell string pan furnace top furnace charge software track device, can very clearly understand the concrete condition of charge, in time provide alarm condition, optimize action sequence.Last batch can match with software track device under the groove with the software track device of blanking tank, so just can reduce main belt and stop number of times, and very fast material loading rhythm improves the material loading ability.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
