Technical field
The utility model belongs to steel-making blast furnace slag granulation device field, particularly a kind ofly overhaul conveniently, the blast-furnace slag granulating device of reusable edible.
Background technology
The good permanent method of general employing is carried out the blast-furnace slag pelletizing technology in the metallurgical industry, water feeding system in the conventional granulating device is to adopt feedwater bag and nozzle to weld together, feed water between bag and the nozzle to being rigidly connected, contain more fine slag in the water of water feeding system utilization, life-time service can wear and tear nozzle pipe, nozzle, feedwater bag; And conventional nozzle length is 250mm, and space for maintenance is narrow and small, and nozzle after the wearing and tearing and feedwater bag are difficult to overhaul and change.
On November 15th, 2004, the disclosed patent No. was that 2,003,201 16779.0 Chinese patent discloses a kind of metallurgical slag granulator that can back and forth dewater, comprise chute, be located at the pelletizer of chute below and the water system and the system of mucking haulage that is correlated with, at least one the dehydration dolly that can back and forth walk, be set in sequence in described pelletizer under, each the dehydration dolly both sides one pair roller respectively is installed; Article two, track is arranged on the both sides of described dehydration dolly, cooperates with described roller, rolls thereon for roller, drives the dehydration dolly and back and forth walks; One trailer wagon is arranged on described two tracks, is connected with described dehydration dolly, is used for traction dehydration dolly; One water leg is arranged on the below of described dehydration dolly, and over against described pelletizer, is connected with water shoot on the water leg, is connected with described water system; At least two slag storehouses are arranged on the both sides of described water leg below respectively compactly, and the width between centers at each center, slag storehouse and water leg center is an integer spacing of described dehydration dolly.This technical scheme does not still solve feedwater bag and nozzle wear and service clearance is little, the problem of maintenance difficult.
The utility model content
The utility model provides a kind of and has overhauled conveniently, maintenance and change the blast-furnace slag granulating device of space enlargement, has solved in the prior art granulating technical barrier of maintenance difficult between the water feeding system and nozzle.
At all deficiencies of prior art, the technical scheme that the present invention proposes is as follows:
A kind of blast-furnace slag granulating device comprises pelletizer, it is characterized in that; described pelletizer mainly is made up of pelletizer casing, granulation wheel, and described granulation wheel is positioned at the pelletizer casing, on the pelletizer casing nozzle is set; described nozzle connects water feeding system, flexibly connects between water feeding system and nozzle.
Adopt metallic hose to flexibly connect between described water feeding system and nozzle.
The metallic hose that described metallic hose flexibly connects to adopting the 1Cr18Ni9Ti material connects.
Between described metallic hose and nozzle, between metallic hose and the water feeding system, be connected by screw thread or flange.
Be socketed in respectively on water feeding system and the nozzle at described metallic hose two ends, belled position adds lock ring.
Described water feeding system is 1～7 feedwater bag, and each feedwater bag connects 1～17 nozzle, and nozzle is uniformly distributed on the pelletizer casing of granulation wheel both sides.
Described water feeding system is 7 feedwater bags, wherein flexibly connects between two feedwater bags and nozzle.
This blast-furnace slag granulating device also comprises slide cinder notch, transmission mechanism, water trap and settling tank; Described slide cinder notch is positioned at described pelletizer top, in the described pelletizer skimming plate is set, and the pelletizer end stretches in the water trap, and settling tank is positioned at a side-lower of water trap; Described water feeding system is positioned at the both sides of pelletizer, wraps the nozzle that flexibly connects on the pelletizer casing by feedwater.
After slag flows out from the slide cinder notch; enter in the pelletizer by transmission mechanism; being dispersed as the little liquation of slag by the granulation of high speed rotating wheel drips; meanwhile water feeding system forms at the nozzle place by the feedwater of feedwater bag and sprays; drop in the little liquation of slag and to carry out shrend in the air; grain slag mixture after the shrend impacts and carry out further granulation on the skimming plate in pelletizer, and the grain slag mixture after the granulation enters water trap and carries out the pulp water separation, and the water after the separation reclaims and flows into settling tank.
Water after wherein pulp water separates residue and supplementary feed after filtration is transported in the water feeding system together.The water that utilizes in the whole like this slag granulation process can recycle, so the water yield of using in the industrial application is also corresponding less.The operating pressure of water feeding system is 0.4Mpa during industrial application, and the water pressure of feedwater bag is 0.4Mpa like this, and the latus rectum by nozzle diminishes, and reaches jeting effect.
The metallic hose of selecting the 1Cr18Ni9Ti material for use between feedwater bag and the nozzle flexibly connects; on the one hand owing to changed in the prior art being rigidly connected between the two; the maintenance difficult problem of having avoided nozzle length to cause inadequately; increased space for maintenance; can when metallic hose damages, effectively utilize the blast-furnace slag granulating device temporary stoppage time in time to change, improve production efficiency greatly.Be stainless steel owing to 1Cr18Ni9Ti in addition, the plasticity of 1Cr18Ni9Ti and toughness height, wear resisting property is good, has also prolonged the life-span of this granulated blast-furnace device accordingly.
The beneficial effects of the utility model are; this blast-furnace slag granulating device overhauls conveniently, overhauls and changes space enlargement; can effectively utilize the short period of shutdown to carry out changing fast and in time, reduce water waste, this device can be widely used in the slag granulation system of metallurgical industry.
