Description

A kind of metal sintered material preheating device
Technical field
The utility model belongs to metal melting equipment field, and in particular to a kind of metal sintered material preheating device.
Background technology
In integrated iron and steel works, sintering is one of main technique of iron mineral powder agglomeration, the sintering deposit of sintering circuit production There is provided 50%~80% or so of iron-bearing material needed for blast furnace process, the material quantity of sintering production processing is very big, the grade 0 of raw material ~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.
Brief description of the drawings
Fig. 1 structural representations of the present utility model;
Fig. 2 is use state of the present utility model with reference to figure;
Label in figure:1 ~ housing, 2 ~ charging aperture, 3 ~ jet head sets, 4 ~ air feed pipe, 5 ~ tracheae, 6 ~ discharging opening, 7 ~ the first guides Plate, 8 ~ the second stock guides, 9 ~ air inlet spray head.
Embodiment
Metal sintered material preheating device shown in 1 ~ 2, including housing 1 with reference to the accompanying drawings, the top of housing 1 sets charging Mouth 2, the bottom of housing 1 sets discharging opening 6, and the bottom of housing 1 sets gas supply assembly, is set in the inwall of housing 1 from lower and alternate Some stock guides 8 of first stock guide 7 and second, make to form a serpentine channel between the first stock guide 7 and the second stock guide 8, the The top of one stock guide 7 and the second stock guide 8 is correspondingly arranged on anti-blocking plug assembly, the gas supply assembly, anti-blocking plug assembly respectively Electrically connect PLC control unit.
Described gas supply assembly includes tracheae 5, valve, flowmeter and air inlet spray head 9, and the air inlet spray head 9 has several, And the bottom of housing 1 is distributed on, described one end of tracheae 5 sequentially connects the blast pipe, valve, flowmeter of sintering furnace, another connection Each air inlet spray head 9.
Described anti-blocking plug assembly includes pressure fan, jet head sets 3 and air feed pipe 4, and the pressure fan passes through air feed pipe 4 Connect jet head sets 3.
