~10mm has reached more than 98%, but temperature only maintains room temperature level.Under common steam, hot water heating mode, steamed because adding
Vapour can only be contacted with partial material, and temperature of charge is uneven；Heating water is only 8% or so to be limited by technique water content, is added water
Amount is limited, and temperature can not reach more than sintering " dew point " temperature；Cause temperature of charge uneven and relatively low, only 35~45 DEG C,
It is difficult to meet the temperature needed for production, " overly moist " phenomenon, and excessive moistening layer became uneven is produced in sintering process, sintering feed is influenceed
The gas permeability of layer, ultimately results in the reduction of sintering production efficiency, cost rise.
Accordingly, it would be desirable to which a kind of temperature that can make sintering feed keeps the uniform, preheating device of stability.
Utility model content
The utility model, which aims to provide a kind of hot waste gas heat energy of utilization sintering process generation, keeps the temperature of sintering feed
Uniformly, the metal sintered material preheating device of stability.
What the purpose of this utility model was realized in：The utility model discloses a kind of metal sintered pre- hot charging of material
Put, including housing, the top setting charging aperture of housing, the bottom setting discharging opening of housing, the bottom setting gas supply assembly of housing,
Some first stock guides and the second stock guide are set from lower and alternate in inner walls, make the first stock guide and the second stock guide it
Between form a serpentine channel, the top of the first stock guide and the second stock guide is correspondingly arranged on anti-blocking plug assembly, the confession respectively
Pneumatic module, anti-blocking plug assembly electrical connection PLC control unit.
Beneficial effect：The utility model carries out repeatedly reinforcing convection current by waste gas from bottom to top and material from top to bottom
After heat exchange, the temperature of material is set to be further increased to 55~75 DEG C, it is ensured that the uniformity of temperature profile of material, consistent；Eliminate burning
" overly moist " phenomenon during knot, hence it is evident that improve the gas permeability of sinter bed, further increase productivity ratio；Meanwhile, pass through
The hot waste gas heat energy for making full use of sintering process to produce replaces steam to be thermal source, saves the consumption of sintering solid fuel, and reduction contains
The environmental pollution caused is arranged outside dirt hot waste gas, energy-conserving and environment-protective is reached, reduces the effect of production cost.
