Description
The utility model belongs to technical field of metallurgical iron-making devices, particularly a kind of blast furnace slag processing device.
Blast-furnace slag of the prior art is handled three kinds of the conventional bath methods, INBA method, figure daraf(reciprocal of farad) that are generally.Wherein conventional bath method floor space is big, industrial pollution is serious, work situation is abominable; The INBA method has been improved work situation, has been reduced pollution, but invest excessive, the whole equipment of factory, state of the art are required very high, be generally used for newly-built large blast furnace; The figure daraf(reciprocal of farad) has changed the way with the shrend granulation, and with the liquid slag Mechanical Crushing, in addition the high pressure water cooling forms slag with the granulation wheel that at a high speed flies to change; compare with the method for Water Quenching Slag; because the reduction of quantity of circulating water reduces investment, floor space reduces; but its shortcoming is relatively poor to the adaptability of blast furnace slag quantitative changeization; when the blast furnace quantity of slag was big, slag granulation and cooling performance were bad, were prone to the black slag of red slag and bulk; so grain slag is second-rate, envrionment conditions is poor than the INBA method.
The purpose of this utility model is to provide a kind of less investment that has, and floor space is little, and working cost is low, and production environment is good, and equipment and facility are simple, maintenance, easy to operate simple, reliable, the blast furnace slag processing device that slag particleization is effective.
The purpose of this utility model realizes by following measure: blast furnace slag processing device is made up of circle round groove, grain slag separator tank, dehydration e Foerderanlage, adhesive tape conveyor, pond, granulation recycle pump etc. of slag ditch, Punched box, water slag groove, grain slag.The slag ditch is connected with the grain slag Punched box, water slag groove connects grain slag Punched box and grain slag circle round groove and grain slag separator tank, circle round transfer lime and the upflow tube of groove bottom of grain slag all is connected with water slag groove behind its groove, vapour collect cover and steam discharge chimney are arranged at the grain slag groove top of circling round, dehydration e Foerderanlage one end places in the grain slag separator tank, the other end is connected with rubber conveyer through the slag dumping funnel, and transfer roller is connected to the grain slag stockyard; The grain slag separator tank is communicated with the pond by overflow port, the overflow ditch of wall top band graticule mesh, and the pond is established the granulation recycle pump and connected the grain slag Punched box through water pipe, valve.
The utlity model has following advantage:
1. floor space is little, and flexible arrangement especially is fit to old factory and transforms.
2. equipment and facility are simple, and transmission apparatus and pipeline and valve are few, and construction investment is few (for a 2500m
3Blast furnace is compared with the INBA method and can be saved surplus the investment about 800 ten thousand yuan), energy consumption is low, operation and easy to maintenance.
3. install safe and reliablely, blast furnace is joined two cover dehydration e Foerderanlages, variation that can the flexible adaptation blast furnace quantity of slag, and can not become the limiting element of blast furnace ordinary production.
4. the production environment condition is good, and the flushing cinder water cycle is used, and does not have outer draining.
5. the slag processing power is big, dewatering efficiency height, grain slag water ratio≤15%.
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described further.
Fig. 1 is the blast furnace slag processing device synoptic diagram.
1 is the granulation recycle pump for pond, 9 for adhesive tape conveyor, 8 for grain slag separator tank, 6 worm conveyors, 7 for the grain slag groove, 5 that circles round for water slag groove, 4 for grain slag Punched box, 3 for slag ditch, 2 among the figure.
The blast furnace slag processing device of present embodiment is made up of circle round groove 4, grain slag separator tank 5, worm conveyor 6, adhesive tape conveyor 7, pond 8, granulation recycle pump 9 etc. of slag ditch 1, grain slag Punched box 2, water slag groove 3, grain slag as shown in the figure.Slag ditch 1 is connected with grain slag Punched box 2, water slag groove 3 connects grain slag Punched boxs 2 and grain slag circle round groove 4 and grain slag separator tank 5, vapour collect cover and steam discharge chimney are arranged at grain slag groove 4 tops of circling round, worm conveyor 6 one ends place in the grain slag separator tank 5, blade on the worm conveyor 6 is provided with treatment hole, the other end is through the rubber conveyer 7 on slag dumping funnel linking grain slag separator tank 5 sides, and transfer roller 7 is connected to the grain slag stockyard; Grain slag separator tank 5 is communicated with pond 8 by overflow port, the overflow ditch of wall top band graticule mesh, and pond 8 is established granulation recycle pump 9 and connected backwater slag Punched box 2 through water pipe, valve.
Blast furnace slag enters the grain slag Punched box 2 that is attached thereto with after molten iron separates through slag ditch 1, carries out slag granulation, and ejection high speed water bundles make the slag water quenching cooling in the grain slag Punched box 2, forms a grain dress grain slag.Grain slag is transported to the grain slag groove that circles round through water slag groove 3 and carries out secondary breaking and coarse filtration for 4 li, grain slag groove 4 substructures of circling round are a circular channels, being convenient to slag circles round in groove, further shrend cooling, in establish steel construction pieces such as impingement plate, backwater baffle plate, filtering grid, feed opening, transfer lime and upflow tube, impingement plate working face surfacing one deck Wimet; Grid is combined by the two-layer evenly distributed steel plate that intersects, the adjacent grid suitable spacing of being separated by, transfer lime and upflow tube all are connected with water slag groove behind its groove, and the transfer lime cross section is faded to trapezoidal by rectangle, upflow tube is terminal to join with the grain slag operculum colpi, and overflow water flows directly into water slag groove; Grain slag circle round the vapour collect cover on groove 4 tops and the steam discharge chimney is collected and discharging furnace slag granulating process in the water vapor that produces.Be transported to collection and the precipitation that grain slag separator tank 5 carries out grain slag from the grain slag grain slag that groove 4 comes out that circles round through water slag groove 3, water slag groove 3 is provided with manual grain slag and distributes gate, in order to carry or to cut off the grain slag of the grain slag dehydration equipment that leads to work or stop; The grain slag that sinks to grain slag separator tank 5 bottoms promotes and dehydration through worm conveyor 6, blade on the worm conveyor 6 is provided with treatment hole, grain slag in rotating and upgrading process through the treatment hole drainage, the water that leaches flows into grain slag separator tank 5 by the return flume that is arranged on worm conveyor 6 belows, grain slag separator tank 5 bottoms are provided with back flushing ring-type water pipe and nozzle, in order to stir grain slag separator tank bottom grain slag to prevent water slag plate knot.Grain slag after the dehydration falls into through the slag dumping funnel on the rubber conveyer 7 on grain slag separator tank 5 sides, and the grain slag rubber conveyer is provided with compressed air blowing cleaner and prevents the airtight sealing cover of water granulated slag steam diffusion.The overflow port of the water that the grain slag separator tank is 5 li by grain slag separator tank 5 wall top band graticule mesh flows into pond 8 after entering the overflow ditch, and the water in the pond is sent to grain slag Punched box 2 and recycles after 9 pressurizations of granulation pumping plant granulation recycle pump.Grain slag is after worm conveyor 6 dehydrations, and the finished product grain slag is delivered to the grain slag stockyard by rubber conveyer 7 and stored and transport outward.
