4, sintering time is short, is heated irregular, and shaping difficulty, powder rate are high.
5, the prereduction rate of ore is low.
6, flue dust is difficult to collect process, large to the pollution of environment.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention proposes a kind of energy-efficient vertical sintering machine.
The highly effective energy-conserving vertical sintering machine that can solve the problems of the technologies described above, its technical scheme comprises body of heater, difference is the suitable for reading of described body of heater is charging aperture, the end opening of described body of heater is discharging opening, described discharging opening is provided with Turbogrid plates, air blast is set from discharging opening to air blast in body of heater, or air exhauster is set from charging aperture to exhausting in body of heater; Body of heater bilateral symmetry above described Turbogrid plates arranges left and right blank plate, on body of heater, the left and right notch for left and right blank plate turnover is offered corresponding to left and right blank plate, cutting cutting edge is offered in the front end of left and right blank plate, and the rear end of left and right blank plate is connected to left and right blank oil cylinder and synchronously stretches out and on the piston rod of retracting.
Conventional design, feeding warehouse is located at the charging aperture of body of heater, and discharge bin is located at the discharging opening of body of heater, and described air blast is by pipeline connection discharge bin.
Further design, the charging aperture of described body of heater arranges bonnet, and described feeding warehouse is located on bonnet, and deduster is communicated in the sidepiece of bonnet by flue.
For preventing the wind direction of left and right blank plate when mineral aggregate is burnt till in cutting in obstruct body of heater, left and right blank plate offers ventilating opening.
The advantage that highly effective energy-conserving vertical sintering machine of the present invention has compared with traditional continuous pallettype sintering machine or circular travelling sintering machine:
1, once igniting gets final product continuous sintering, eliminates traditional approach coal gas continuous ignition device.
2, owing to adopting the air blast mode of lower portion of furnace body, make full use of sintering furnace charge cooling residual heat preheating ore, energy consumption is only 50% of conventional sintering mode.
3, device structure is brief, and cost of investment is low, is only 40% of conventional sintering equipment investment.
4, the time of staying of sintered products in body of heater is long, and being heated evenly, sintered products is shaped, powder rate is low, is 50% of conventional sintering mode product powder rate.
5, because thickness of feed layer in body of heater significantly increases, ore pre-also effective, prereduction rate is high, and the prereduction rate of conventional sintering mode product ore is only 70%, and the prereduction rate of ore sintering product of the present invention can reach more than 90%.
6, sealing structure of the present invention is high, and smoke spillage rate is low, fuel consumption is low, and environmental pollution is little.
