Description
Technical field
The utility model relates to Research for Feeding Raw Materials System field, and particularly a kind of blast furnace revert system concentrates storing to concentrate the equipment of discharge.
Background technology
Charging of blast furnace screening system, when getting the raw materials ready screening, the flow of the fine ore that every batch of material produces and coke breeze is at 40 ~ 80t/h, high returning charge about the 10t produced, screening in every 5 minutes once, 7 minutes about time length of belt-conveying returning charge, returning charge all belts when burnt system is normally produced with system of returning mine that return of blast furnace operate throughout the year.Due to continual running all the year round, make the serious wear of the conveyor of blast furnace return conveyer system, step-down gear and the transmission apparatus such as cylinder, carrying roller thereof, shorten the work-ing life of belt, add the power cost of enterprise operation.
Summary of the invention
The purpose of this utility model is to provide a kind of blast furnace revert system and concentrates storing to concentrate the equipment of discharge, the wearing and tearing of the conveyor of blast furnace return conveyer system, step-down gear and the transmission apparatus such as cylinder, carrying roller thereof can be reduced, extend the work-ing life of belt, reduce the power cost of enterprise operation.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of blast furnace revert system concentrates storing to concentrate the equipment of discharge, comprise storage bin, feed opening, A level gage, B emergency gate, C electric gate valve, described storage bin is arranged on the blanking mouth place of the Article 1 return conveyer in blast furnace revert system, the upper end of storage bin is provided with feed opening, the lower end of storage bin is provided with C electric gate valve, A level gage is installed in storage bin, in storage bin lower lateral, B emergency gate is installed.
Compared with prior art, the beneficial effects of the utility model are:
A kind of blast furnace revert system concentrates storing to concentrate the equipment of discharge, owing to having installed storage bin between Article 1 return conveyer and Article 2 return conveyer, the breeze of come to Article 1 belt-conveying or coke powder carry out concentrated storing and " suppress storehouse ", when concentrated storing " suppresses storehouse ", by all transport return conveyer system-downs of next stage, the total runtime of return conveyer system can be shortened, reduce the conveyor of blast furnace return conveyer system, step-down gear and cylinder thereof, the wearing and tearing of the transmission apparatus such as carrying roller, extend the work-ing life of belt, reduce the power cost of enterprise operation.
Accompanying drawing explanation
Fig. 1 is the structural representation that storing can be concentrated in the utility model to concentrate the blast furnace revert system of discharge;
Fig. 2 is the structural representation of storage bin in the utility model;
In figure: 1-storage bin 2-Article 1 return conveyer 3-feed opening 4-A level gage 5-B emergency gate 6-C electric gate valve
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
As shown in the figure, a kind of blast furnace revert system concentrates storing to concentrate the equipment of discharge, comprise storage bin 1, feed opening 3, A level gage 4, B emergency gate 5, C electric gate valve 6, see Fig. 1, described storage bin 1 is arranged on the blanking mouth place of the Article 1 return conveyer 2 in blast furnace revert system, see Fig. 2, the upper end of storage bin 1 is provided with feed opening 3, the lower end of storage bin 1 is provided with C electric gate valve 6, in the upper end of storage bin 1 inside, A level gage 4 is installed, in storage bin 1 lower lateral, B emergency gate 5 is installed.
Charging of blast furnace screening returning charge haulage system is two cover belt transportation systems, respectively returning charge transport fine ore and coke breeze.The utility model return mine and the Article 1 belt blanking mouth place returned in burnt belt system install respectively storage mineral powder bin and storage coke powder storehouse.Storage mineral powder bin and the volume settings of storing up coke powder storehouse are 300m by the returning charge amount that the volume in storage mineral powder bin and storage coke powder storehouse produces according to blast furnace and determine in the present embodiment
3.
B emergency gate 5 is in closing condition when normal, and when an accident occurs, B emergency gate 5 is opened discharge of materials to ground.
In addition, in order to prevent breeze or the fluffy material of coke powder of storage bin 1C electric gate valve 6 in winter place discharge gate, freeze, cannot discharge, coal gas can be installed to frozen breeze or blowing of coke powder in the bottom of storage bin 1, or lagging facility is installed freezes to prevent C electric gate valve 6 place discharge port.
A kind of adopt blast furnace revert system to concentrate storing to concentrate the equipment of discharge to carry out the method that discharge concentrated by concentrated storing, concrete steps are as follows:
1) when blast furnace is when sieving, close the C electric gate valve 6 of storage bin 1, screening thing is transported to storage bin 1 by Article 1 return conveyer 2, now by all transport return conveyer system-downs of subordinate.
2) measured by A level gage 4, when charge level in storage bin 1 reaches setting material level, start subordinate's transport return conveyer system, open C electric gate valve 6, by the control to C electric gate valve 6 aperture, control the flow of subordinate's return conveyer, concentrate and the breeze in storage bin 1 or coke powder are discharged by Article 2 return conveyer and subordinate's belt-conveying.
3) after storage bin 1 is emptying, again by all transport return conveyer system-downs of the C electric gate valve 6 of storage bin 1 and subordinate.Continue storing and " suppress storehouse ".
When blast furnace is normally produced, if blast furnace revert system runs repeatedly according to above step, then revert system all can be in stopped status most of the time every day.When concentrated discharge is at 2 hours, by Automated condtrol, " suppressing storehouse " storing concentrates the process of discharge can carry out 3 ~ 4 circulations every day.As can be seen here; within 24 hours in the prior art, do not stop transport turn belt; in the utility model, there is half the time to be in stopped status; while having saved electric energy; reduce the wearing and tearing of the transmission apparatus such as motor, step-down gear, cylinder and carrying roller; also extend belt work-ing life, greatly improve the conveying efficiency of belt.
