Background technology
Steel and iron industry is the AND ENERGY RESOURCES CONSUMPTION IN CHINA rich and influential family, and energy consumption accounts for 15% of national total energy consumption.In steel manufacture process, the energy consumption of sintering circuit occupies the second, and in SINTERING PRODUCTION, the heat sinter sensible heat accounts for more than 40% of overall heat consumption, and sintered, energy saving is very important.It is the effective way that improves the steel and iron industry efficiency that high efficiente callback utilizes sintering mine sensible heat.
The conventional sintering machine is subjected to cooling process technology limit, causes that air quantity is large, wind-warm syndrome is low, and UTILIZATION OF VESIDUAL HEAT IN efficient is low.Employing stove formula is cooling can significantly improve flue-gas temperature, improves UTILIZATION OF VESIDUAL HEAT IN efficient, improves generated energy.The high temperature bulk sintering deposit that sintering deposit particle size influences heat exchange efficiency, sintering machine produce must through after fragmentation in stove with the cooling-air countercurrent flow, the refrigerating gas heat absorption is more abundant, exit gas temperature is higher, Air Quantity Required is less, generated energy is larger, remarkable benefit.
How to improve finished product sintering deposit quality, particle size uniformity after the ore deposit fragmentation of assurance high temperature sintering satisfies the cold heat exchange requirement of stove, is the key of the cold sintering machine cogeneration of stove.
The utility model content
In order to solve the problems of the technologies described above, it is a kind of for the cooling sintering deposit high-temperature crushing device of stove formula that the utility model provides, can solve sintering mineral aggregate size bigger than normal, the problem that cooling effect is poor, obtain to increase the contact area in cooling furnace air and hot ore deposit, strengthen the effect of the heat exchange of hot mineral aggregate and air.
For achieving the above object; The technical solution of the utility model is: a kind of for the cooling sintering deposit high-temperature crushing device of stove formula; Comprise discaling roll; The grate plate; Mobile trolley used; Movable rail; Jack; Reductor and motor; The grate plate be fixed on mobile trolley used on; Discaling roll is arranged on above the grate plate; Discaling roll is connected by reductor discaling roll shaft coupling with reductor; Reductor is connected by the motor reducer shaft coupling with motor; Crushing teeth on described discaling roll is axially alternately evenly arranged along discaling roll; Adjacent row's crushing teeth interlaced arrangement; The level interval of adjacent row's crushing teeth is 200mm; Be 400mm with adjacent crushing teeth spacing in row; Grate lath spacing adjacent on described grate plate is 200mm.
The inner water-cooled that adopts of described discaling roll reduces roller body core temperature.
The crushing teeth of described discaling roll adopts anti-friction material, and crushing teeth adopts Wear-resistant white cast iron material.
Described mobile trolley used being arranged on movable rail.
The beneficial effects of the utility model:
1) reduce high temperature sintering ore particle degree, increase the heat convection area of the interior hot ore deposit of stove and air, enhanced heat exchange promotes flue-gas temperature to the 600 ℃ left and right of coming out of the stove, and the waste heat boiler steam parameter can adopt medium temperature and medium pressure, significantly promotes residual heat generating efficiency;
When 2) movable rail can facilitate equipment fault, mobile trolley used withdrew from, and facilitated the discaling roll maintenance;
3) hot ore particle degree reduces and can wear and tear by the aggravation crushing teeth, and crushing teeth adopts Wear-resistant white cast iron material;
4) sintering deposit high temperature can shorten service life of equipment, and the inner water-cooled that adopts of discaling roll reduces the discaling roll core temperature, extension device service life.
