Technical field
The present invention relates to blast-furnace technique field in ironmaking, waste material cleaning system in a kind of large blast furnace overhaul stove is specifically provided
System and method for cleaning.
Background technology
Currently, when well known large blast furnace overhaul, there are two types of methods for waste material cleaning in stove, and one is by gas welding stove
Shell is locally cut open, and removes refractory brick in part cooling wall and stove, then, by mechanical equipment by residual iron grumeleuse in stove and waste material one
And clear up and come out of the stove, finally furnace shell is restored to the original state, cooling wall is installed, builds refractory brick by laying bricks or stones.The speed of such method waste material cleaning
Degree is very fast, and still, resilient, cooling wall connection water pipe are not also easy to produce strain cracking leak, refractory brick for furnace shell breakage deformation
The old and new's joint part is also easy to produce gap and oozes iron, or even causes hearth breakout accident.
Another kind is not destroy furnace shell, by set up scaffold, manually by the original methods such as pneumatic pick, sledgehammer, drill rod into
Row manual cleaning finally has bad luck slag iron from air outlet, iron mouth outward.Since iron dirt is abnormal solid in stove, in addition having a large amount of residual
Iron, cleaning are got up extremely difficult, and not only labor intensity is big, and time-consuming, if encounter residual iron in stove it is big when, clearance time is long
It is longer up to the dozens of days even time.
Invention content
In order to solve the above technical problem, the present invention provides waste material cleaning system in a kind of large blast furnace overhaul stove and clearly
Reason method is analyzed and is proved by the furnace structure to entire blast furnace, is hoisted in blast furnace burner hearth using by excavator, by
Mechanical execution replaces the method for manual work to quickly clean waste material in stove, and adds motorized pulleys belt feeder and have bad luck, existing to solve
Have in technology, the problems such as furnace shell breakage deformation not resilient, manual cleaning labor intensity is big, and clearance time is long.
The invention is realized in this way waste material cleaning system in a kind of large blast furnace overhaul stove, including drum belt machine A,
Stem bar A, drum belt machine B, stem bar B and slag ladle, drum belt machine A are located on tuyere platform, and blast furnace air outlet is stretched into one end, separately
It is located at out on the platform of ironworks with contact connectio at the top of stem bar A, drum belt machine B below one end, the lower ends stem bar A and drum belt
The upper surface of one end machine B connects, and stem bar B is connected below the other end of drum belt machine B, slag is directed at immediately below stem bar B
Tank.
Further, in blast furnace, it is equipped with excavator A and excavator B, the working end of excavator A is hydraulic hammer, excavator
The working end of B is scraper bowl.
Further, the slag ladle is equipped with multiple, and each slag ladle is arranged on trolley, and trolley is sequentially connected with, by headstock
Traction.
Further, the width of the drum belt machine A and drum belt machine B are 1.2m.
A kind of method for clearing up waste material in cleaned system stove using waste material in above-mentioned large blast furnace overhaul stove is provided, including such as
Lower step：
1) waste material in stove is placed on drum belt machine A, drum belt machine by waste material transportation to stem bar A, waste material along
Stem bar A is transported on drum belt machine B；
2) waste material is continued to transport by drum belt machine B, to end after slided from stem bar B, fall into slag ladle.
Further, excavator A and excavator B is equipped in the blast furnace, the working end of excavator A is hydraulic hammer, is excavated
The working end of machine B is scraper bowl, and excavator A is responsible for broken waste material, and excavator B is responsible for waste material being transported on the drum belt machine A.
Further, operating room and body are separated by excavator A and excavator B outside blast furnace, is hung successively from manhole
It is transported in blast furnace, is re-assemblied in blast furnace.
Further, the slag ladle is equipped with multiple, and each slag ladle is arranged on trolley, and trolley is sequentially connected with, by headstock
Traction, after first slag ladle fills waste material, headstock trailer wagon forward, by second slag ladle draw to the stem bar B just under
Side, each slag ladle is filled to cleaning waste slag finish successively.
Compared with the prior art, the advantages of the present invention are as follows：
1, it constructs, is avoided since resilient, guarantee be not cold for furnace shell breakage deformation under the premise of not destroying furnace shell
But wall connection water pipe is not deformed cracking leak, need not build refractory brick by laying bricks or stones again.
2, excavator is hung in stove using special scheme, the clear material of machinery, belt haul, greatly improve expect clearly in stove into
Degree, it is safe and environment-friendly, it is domestically leading.
3, manual work is replaced by mechanical execution, greatly improved work efficiency, effectively shorten waste material in blast furnace overhaul stove
The construction time is cleared up, construction cost is saved, shortens total time of construction, blast furnace is enable to produce in advance.
4, it avoids and manually carries out manual cleaning by original methods such as pneumatic pick, sledgehammer, drill rods, cross-operation increases
The safety coefficient of work progress in State of Blast Furnace.
5, the technology of the present invention is innovated, and is popularized in an all-round way and is applied, and achieves good result, generate great economic benefit and
Social benefit.
