Two, operating method explanation

1, sintering process will guarantee the supply of heat sinter continuous-stable, while guarantee the stabilization of its ingredient and temperature, to the greatest extent Hot mine mean temperature may be improved.

2, the operating principle of this process system is to reduce circulation as far as possible under the premise of guaranteeing to be sintered cold mine dump temperature Air quantity promotes the temperature of hot fume, while the control of waste heat boiler delivery temperature is in suitable temperature.

3, the packing speed of heat sinter is adjusted by controlling the revolving speed speed of distributing device 7, operating principle is to try to It reduces revolving speed speed to adjust, keeps feed rate balanced.

Three, it illustrates

The working principle of the utility model

The utility model exchanges heat according to cold and hot medium counter flow, and the highest principle of heat exchanger effectiveness carries out technological design, passes through Distributing method is cleverly designed, thus realize the equalization stable of uniform the segregation-free phenomenon and heat transfer process of material filling, thus Realize efficient UTILIZATION OF VESIDUAL HEAT IN.The method that the utility model utilizes cooling wind closed cycle work, passes the gas through seven or eight hundred degree High-temperature material, the oxygen content in gas is reduced and 5% or less is recycled, make raw sinter can not double sintering and environment it is dirty Dye problem.

Four, the key point of the utility model and point to be protected

Realize that sealing and uniform distribution avoid material segregation heat exchange using seal pipe, distributing device, it is closed circuit using recuperated gas The method that the technology of circulation is sintered the vertical cooling heat transferring of mine,

Key point: it A, is realized using seal pipe 6, with the cooperation of distributing device 7 ventilative equal in sealing and uniform distribution, heat exchanging chamber Even, heat exchange thoroughly, obtains high efficiency heat exchange.

B, distributing device is equipped with the deflector chute of multiple and different length, non-co-content, realizes the uniform distribution of segregation-free.

C, it is provided with Minitype dust collector 16 on cool air hose 18, mini fan 17, regulating valve 24, passes through exhaust regulating valve 24 Adjust discharge gas flow number, control heat exchanging chamber in and velocity-reducing chamber in vacuum magnitude, reach feed inlet and formed with discharge port Negative pressure avoids fugitive dust from eliminating pollution.

D, the high-temperature material that seven or eight hundred degree are passed the gas through using the technology of recuperated gas closed cycle, by containing in gas Oxygen amount reduces by 5% or less and is recycled, and makes raw sinter can not double sintering.Avoid the raw material and oxygen two not cooked completely Secondary sintering, the disastrous effect for causing to stop production can not be discharged by striking up partnership in heat exchanging chamber.

E, the design of heat exchanging chamber 10 circularizes, and has reached cooling gas from the air inlet simultaneously of inner and outer ring lower part, has reached cooling gas It is more evenly distributed, exchanges heat more thorough.

F, dredging machine 12 selects electric hydraulic push rod or hydraulic push rod and air-leg, plays and destroys scaffold phenomenon, makes stream It is unobstructed.
