Mainly one or more collector mats are arranged by sinter on circular cooler trolley top in the mode of current UTILIZATION OF VESIDUAL HEAT IN
Heat smoke is generated in cooling procedure to collect, and will be collected heat smoke feeding afterheat utilizing system and is used.
Studies have shown that the temperature of sintering ore bed is larger along short transverse difference in distribution in the trolley of sintering machine tail portion, such as Fig. 1 institutes
Show, upper surface is sintered ore bed temperature has been environment temperature, and mine temperature is unloaded far below sinter in ring cold machine, and lower layer's sinter
Layer temperature is in the condition of high temperature due to combustion.Fig. 2 is traditional cooling technique sinter discharging schematic diagram, 1 ＇'s of sintering machine
Sintering ore bed in 2 ＇ of tail portion trolley uniformly carries out discharging, is crushed into 3 ＇ of single roll crusher, mine is unloaded using sintering machine
After 4 ＇ that struggle against are collected, into 5 ＇ of ring cold machine distribution device, it is cold to be evenly arranged in ring for sinter after being crushed using distribution device
Cooling operations are carried out on 6 ＇ of machine trolley, such mode has the following problems：
First, low-temperature sintering ore bed temperature is far below ring cold machine discharge temp, cooling operations are carried out without entering ring cold machine,
Traditional cooling technique increases the unnecessary sinter treating capacity of ring cold machine.
Second, currently employed sinter circulating cooling waste heat reclaiming process, into the temperature of the cooling air of circular cooler trolley
Degree has been higher than the temperature of low-temperature sintering ore bed, so low-temperature sintering ore bed will absorb the heat of cooling air, reduces sinter
Waste heat flue-gas temperature.
Therefore, ring cold machine treating capacity how is reduced, the cost of ring cold machine is reduced, improves sinter waste heat recovery volume, is this
Field technology personnel's technical issues that need to address.

Degree, so realizes the separation of high temperature and low-temperature sintering ore bed, the low-temperature sintering ore bed after separation is crushed by double-geared roller crusher
Afterwards, it is directly utilized, high temperature sinter, which then enters, carries out cooling operations in ring cold machine 10.
The adjustment process of shovel flitch 2 is as follows：First according to the testing result of temperature-detecting device, 2 top of shovel flitch is determined
Proper height, be adjusted using hydraulic system, be adjusted, be sintered in the temperature of ore bed according to bed temperature distribution situation
When rising, the angle of shovel flitch 2 increases, and the top of shovel flitch 2 rises to low temperature and high temperature sinter layer separation height；It is sintered ore bed
Temperature when reducing, the angle of shovel flitch 2 reduces, and the top of shovel flitch 2 drops to low temperature and high temperature sinter layer separation height；
Then mobile wheel is utilized to adjust the lateral position on the top of shovel flitch 2, according to the lateral position on sinter top and sinter
Emptying point situation, so that it is in the position in the emptying point of sinter always, i.e. it is left be in emptying point for the top of shovel flitch 2
It when side, is moved right using wheel 5, shovel flitch top is made to be in emptying point position；The top of opposite shovel flitch 2 is in emptying point
It when right side, is moved to the left using wheel 5, shovel flitch top is made to be in emptying point position.
Since low-temperature sintering ore bed is directly entered follow-up screening process, reduce ring cold machine treating capacity, ring cold machine area and
Air quantity can greatly reduce, and reduce the construction cost and operating cost of ring cold machine 10, meanwhile, only high temperature sintering ore bed enters ring
Cold 10, sinter initial temperature improves in ring cold machine 10, and the temperature of heat smoke will be sharply increased, and improves sinter waste heat and returns
Receipts amount.
Certainly, sinter cooler is not limited to circular cooler, can also be vertical cooling machine or straight line cooler
Deng, moreover, the position of the first unloading mine bucket 6 and the second unloading mine bucket 7 is not fully confined to underface and obliquely downward, it can be according to need
It is adjusted.
