Description
Technical field
It is used for conversion equipment of the blast furnace slurry when being conveyed to different filtering ponds the present invention relates to a kind of, belongs to blast furnace
Ironmaking equipment technical field.
Background technology
Blast furnace slurry conversion equipment be responsible for grain slag conveying with shunting, realize water used in grain slag region recycle with it is used
The recycling of slag.Slurry conversion equipment is located between slag runner and two filtering ponds, and its effect is when blast furnace casting, to incite somebody to action
The grain slag discharged by slag runner guides filtering ponds into, after side filtering ponds are filled up by grain slag, the distributor changed using slurry, will
Grain slag is incorporated into another filtering ponds, continues to output grain slag, until end of tapping a blast furnace, then grain slag realizes pulp water in filtering ponds
Separation, slag realizes recycling, and water is realized and recycled.The slurry conversion equipment used at present drives slag using feed screw apparatus
Starch pipeline to swing, slurry is transported to different filtering ponds.The shortcoming of this structure is obvious, on the one hand, because slurry pipeline is needed
Swing, thus leading screw is subjected to the effect for the power that the Zola right side is dragged for a long time, easily occurs bending and deformation, it is necessary to frequently change silk
After thick stick, and leading screw flexural deformation to a certain extent, it will the effect that pipeline swings can not be completed, so as to cause grain slag to overflow
Go out filtering ponds, due to grain slag high temperature, thus surrounding enviroment can be caused with expendable destruction；On the other hand, slurry pipeline
Swing, it is necessary to which the material of sludge suction rubber pipe is flexible material, wearability is poor, and sludge suction rubber pipe is located at the lower section of slag runner, not only
The souring of grain slag from top to bottom is born, and grain slag temperature is very high, directly contribute the destruction to sludge suction rubber pipe, thus
During the use of sludge suction rubber pipe, it is very easy to abrasion and even occurs mill leakage phenomenon, once occurring mill leakage, will cause outside grain slag
Let out, because its temperature is very high, surrounding enviroment will be caused with serious destruction, its consequence is unable to estimate, it is therefore desirable to find abrasion
Sludge suction rubber pipe is changed immediately, because abrasion is more frequent, thus sludge suction rubber pipe changes very frequent, because its cost is high, changes
Time is long, frequently changes and adds spare parts cost, cost of labor, the maintenance difficulties of equipment is improved, while sludge suction rubber pipe only has
It could be changed in blast furnace staying, thus, it is necessary to which blast furnace is forced damping down just if being worn and torn in the period of non-periodical repair plan
It can complete to change, heavy damage conditions of blast furnace brings huge economic loss to enterprise.Damage to meet an urgent need to take simultaneously and put
Dry slag measure, causes to have a strong impact on to periphery bad border.
Because existing blast furnace slurry conversion equipment has disadvantage mentioned above, adverse effect is caused to blast fumance, still
So far without good solution, the problem as puzzlement blast fumance, it would be highly desirable to solve.

Fig. 1 shows that the basic platform 1 of concreting is located between slag runner 2 and two filtering ponds, and a point slag pipeline 3 is located at
On basic platform 1.Basic platform 1 is in level height of the level height higher than two filtering ponds sides of the side of slag runner 2, point slag
Level height of the bottom surface of pipeline 3 in the side of slag runner 2 is higher than the level height two filtering ponds sides.Basic platform 1 and point slag
The height that pours of pipeline 3 is tilted from slag runner 2 to two filtering ponds directions, keeps certain gradient, is easy to slurry automatic from slag runner 2
Flow to filtering ponds.
Fig. 1 shows, because point slag pipeline 3 directly bears high temperature grain slag washing away from the top down, in order to prevent that pipeline from being rushed
Brush is damaged, designs and inlays one layer of carborundum liner plate 4 in the inside of point slag pipeline 3, strengthens its wearability.
Fig. 1 shows that one end of point slag pipeline 3 is main pipeline, and main pipeline slag inlet is connected with slag runner 2, point slag pipeline 3
The other end is two laterals, and the slag inlet of two laterals is connected with the slag notch of main pipeline, two laterals
Slag inlet of the slag notch respectively with two filtering ponds be connected, the slag inlet of two laterals is respectively mounted gate 5.Pass through
The alternating of two valves 5, which is opened and closed, to be injected separately into slurry to two filtering ponds, realize the conversion conveying of blast furnace slurry.
Fig. 1,2 displays, gate 5 are made up of column 12, crossbeam 13, track 14, flashboard 15, lifting rod 16.Each gate 5
There are two columns 12 both sides respectively, and two columns 12 fix the entrance both sides for being cast in point lateral of slag pipeline 3, and two are stood
The upper end of post 12 is connected by crossbeam 13, and the inner side of two columns 12 is respectively mounted track 14, and the both sides of the edge insertion of flashboard 15 is in-orbit
In road 14, flashboard 15 is with track 14 to be slidably matched, and lifting rod 16 is vertically fixed in the upper end of flashboard 13, and the upper end of lifting rod 16 is passed through
Lifting hole on crossbeam 13 is connected with hoisting mechanism.
Fig. 1 shows that there is lifting platform 6 top of gate 5, and two groups of hoisting mechanisms are separately mounted on lifting platform 6, and two groups carry
Mechanism is risen respectively with two upper ends of gate 5 to be connected.Hoisting mechanism is made up of motor 7, reductor 8, reel 9, steel wire rope 10, electricity
Machine 7 is connected by shaft coupling 11 with reductor 8, and the output shaft of reductor 8 is connected with the axle of reel 9, one end of steel wire rope 10
It is wrapped on reel 9, the other end of steel wire rope 10 is connected with the upper end of lifting rod 16 of the top of gate 5.
The reel 9 of one embodiment of the present of invention uses key type of attachment with the connection of reductor 8, justifies in the side of reel 9
On, open a φ 20 hole, by steel wire rope 10 through clot and being fixed with steel wire rope card behind φ 20 hole, steel wire rope 10 it is another
One end is passed through after the gudgeon bearing pin on the top of lifting rod 16 of gate 5, is equally fixed using steel wire rope card.
Fig. 2 shows that when gate 5 is opened, gate 5 is under conditions of deadweight, in order to prevent the pendant suddenly of gate 5
Under, gate 5 bottom center weld a retainer ring 17, and two siding tracks 14 towards filtering ponds direction upper side
A retainer ring 17 is respectively welded, the retainer ring 17 of track 14 is relative with the position level of retainer ring 17 of gate 5, and cremorne bolt 18 is through
In the retainer ring 17 of track 14 and gate 5, gate 5 is fixedly connected with track 14, so as to realize that gate 5 opens stable, prevented
The effect fallen.
In order to prevent gate hoist structure from breaking down in the process of running, cause gate 5 normally-open, in lifting
The front end of platform 6 is welded with hanger, and the position of hanger is located at the relative lifting platform 6 in two 5 top lifting rod of gate, 16 tops
Side wall on.When gate 5 can not use hoisting mechanism to open, hanger is realized as the fixing end of jack using jack
Gate 5 it is normally-open.
The size of flashboard 15 of gate 5 is identical with the inside dimension of lateral, because flashboard 15 often bears rushing for grain slag
Brush, flashboard 15 strengthens its wearability, track 14 uses 20#B channel-section steels, at track 14 and gate 5 using 25mm manganese steel plate
The top transported in grain slag, is in the environment of vapor for a long time, and surface is perishable to be damaged, and causes body distortion, gate 5 can not
Normal switch is completed, thus design uses anticorrosive paint to brush its surface, and brushed again on the top of anticorrosive paint
One layer of butter, as the lubricant of gate 5 and track 14, and serves carry out secondary guarantor to track 14 to a certain extent
The effect of shield.
