Place is disposed with more discharge devices.Temperature detection instrument can be used to carry out temperature detection to the sinter that each discharge gate is discharged.
Vertical cooling machine volume is larger, and surface area is also very big, and the detection of temperature of charge is for cooling in vertical cooling machine tank
The control to Boiler pressure control and ore discharge temperature of wind is most important.Inventor has found in the implementation of the present invention, existing
It is typically all that temperature detection is carried out to the sinter being discharged from vertical cooling machine in technology, when observed temperature deviates target temperature
Take control measure such as adjustment to air quantity again, however the temperature data of this method detection seriously lags, material reaches discharge gate
If Shi Wendu is too low to illustrate that heat exchanger time is long, early air quantity may should be reduced, and if the excessively high explanation of temperature may be early
Air quantity should just be increased, or even had little time to cool down sinter by increasing cooling air quantity again at this time, can only finally stop arranging
Material to avoid the hot mine of discharge blows downstream belt, and stops discharge and easily cause material in tank because of the carbon residue that locally burns incompletely
Burning cause the superfusion of hot mine form bulk and can not discharge, or even vertical cooling machine is blocked, causes serious consequence.

Specific implementation mode
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent and the consistent all embodiments of the present invention.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects being described in detail in claims, of the invention.
Fig. 1 is the stream according to a kind of vertical cooling machine temperature of charge detection method shown in an exemplary embodiment of the invention
Cheng Tu.Temperature-detecting device used in this method is inserted into described vertical through the trepanning ecto-entad on the vertical cooling machine kiln wall

The second mean value is obtained, wherein second mean value is the equal of the temperature value that the non-contact temperature measuring instrument repeatedly measures
Value；
Using the difference of first mean value and second mean value as the coefficient of relationship.
Also relationship can be calculated by following formula based on step S201 and step the S202 data measured respectively
Coefficient k：
In above formula：
K, the coefficient of relationship between measured temperature and actual temperature value, unit DEG C；
Ti, the data that temperature-detecting device (thermocouple) thermometric obtains, unit DEG C, i=1,2 ..., n；
Tj, the temperature data (i.e. calibration temperature measurement data) that non-contact temperature measuring instrument measures, unit DEG C, j=1,2 ..., m.
Above formula is measured with thermometric multigroup temperature data with temperature-detecting device of the present invention multigroup by calibration
Temperature data is compared, and temperature gap coefficient is found out.It measures calibration number (the n values i.e. in formula and m values) and carries out more accurate
Exactness is higher.By the coefficient of relationship that calibrates in advance of the present invention plus observed temperature value to get to actual temperature of charge, relationship
Formula is：
T=T0+k
In above formula：
K, the coefficient of relationship between measured temperature and actual temperature value, unit：℃；
T0, the data that temperature-detecting device (thermocouple) thermometric obtains, unit：℃；
T, counted test point material actual temperature, unit：℃.
In addition, can also be advanced optimized to k values.It is shown in Figure 3, in the present embodiment or other certain implementations of the invention
In example, the method can also include：
Step S301 obtains the coefficient of relationship in multiple and different times.
Step S302 obtains the coefficient of relationship mean value for the coefficient of relationship that the multiple different time obtains.
Step S303, using the coefficient of relationship mean value as obtaining relationship system used in the actual temperature value step
Number.
To obtain more accurate k values, multiple (such as n times) calibration may be used, that is, when respectively obtaining multiple (n) differences
Between when k values, then average treatment, such as following formula again：
In above formula：
K, the coefficient of relationship between measured temperature and actual temperature value, unit DEG C；
ki, the coefficient of relationship that ith obtains, unit DEG C, i=1,2 ..., n.
It is easily understood that the n onrelevants in n herein and step S201.
The temperature-detecting device in the embodiment of the present invention is further described by example again below：
In the present embodiment or other of the invention some embodiments, the predeterminated position be the vertical cooling machine air feed into
At mouthful, alternatively, at the vertical cooling machine bottom discharging mouth.Or may be that the vertical cooling machine kiln wall is any required
The position for detecting temperature, to this embodiment of the present invention and is not limited.
As example reference can be made to shown in Fig. 4, in Fig. 4,400 be vertical cooling machine, and material (i.e. heat sinter, in Fig. 4 not
Draw) enter after vertical cooling machine 400 from top entry storehouse and falls naturally due to gravity；It can be in air feed entrance cross section week
Setting temperature-detecting device 401, can also be transversal at bottom discharging mouth to detect by air feed temperature of charge after cooling on side
Temperature-detecting device 402 is arranged to detect temperature of charge before discharge in face periphery.403 be blast pipe (or perhaps air duct), is used
