Embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail; Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
Embodiment one:
As shown in Figure 1: a kind of adjustable for height slag dry method centrifugal granulation equipment of the present embodiment, comprise water cooler 1 and pelletizer, the cooling stave that described water cooler 1 comprises opening for feed 5, discharge port 6 and is arranged on water cooler inwall, described pelletizer comprises swivel arrangement 21 for making centrifugal granulation to slag 7 and for the setting device 22 to swivel arrangement 21 lifting effect; Described opening for feed 5 is provided with the proofing unit I for detecting slag 7 fluctuations in discharge.Described swivel arrangement 21 can adopt revolving cup, rotating disk, plate-spinning or rotary drum; Described setting device 22 can adopt hydraulic structure or physical construction to carry out height control.In present case, swivel arrangement 21 adopts revolving cup, and setting device 22 adopts the mode of hydraulicefficiency governing.Equipment of the present utility model by the real-time detection of opening for feed slag 7 flow to adjust the height of pelletizer; ensure that slag 7 is when different flow; the cooling intensity of high temperature slag particle 8 after granulation in water cooler is substantially identical, thus slag particle 8 temperature out is consistent substantially.
Concrete, due in the dry method centrifugal granulation of blast furnace slag, after granulation, the height of temperature is closely connected with slag uninterrupted, namely in the flushing cycles of blast furnace slag, slag fluctuations in discharge clearly, default flows is less, then increase gradually, pelletizer and cooling stave keep changeless words, then there will be discharge port 6 slag particle temperature first low rear high situation, when there is difference in discharge port 6 slag particle temperature and design temperature, in order to not affect the stable conditions of follow-up system because of the fluctuation change of slag particle temperature out, and not because of slag particle temperature too high time, there is inter-adhesive one-tenth block, the problems such as glass rate is on the low side, slag fluctuations in discharge by arranging proofing unit I 3 pairs of opening for feeds 5 detects, and the height of pelletizer is regulated according to the slag flow diameter that it detects, to reach the substantially identical object of the cooling intensity of high temperature slag particle in water cooler after controlling granulation, in present case, described proofing unit I 3 is video detector.
Concrete principle of work is:
1), at the tap cinder initial stage, because the slag flow of opening for feed 5 is less, namely the diameter of slag stream stock that detects of proofing unit I 3 is thinner, swivel arrangement 21 is allowed to reduce by setting device 22, make the impingement position of slag particle and cooling stave lower, shorten the duration of contact of slag particle on cooling stave, thus make slag particle can not undercooling on cooling stave, cause landing in the slag particle temperature of discharge port 6 far below the temperature value of technique initialization;
2), in tap cinder mid-term, due to the slag stability of flow of opening for feed 5, namely the diameter of slag stream stock that detects of proofing unit I 3 is thicker, swivel arrangement 21 is allowed to raise by setting device 22, make the impingement position of slag particle and cooling stave higher, increase the duration of contact of slag particle on cooling stave, thus slag particle is fully cooled on cooling stave, allow landing can not far above the temperature value of technique initialization in the slag particle temperature of discharge port 6;
3), in the tap cinder later stage, because the slag flow of opening for feed 5 reduces, namely the diameter of slag stream stock that proofing unit I 3 detects attenuates, swivel arrangement 21 is allowed to reduce by setting device 22, the impingement position of slag particle and cooling stave is reduced, shorten the duration of contact of slag particle on cooling stave, thus make slag particle can not undercooling on cooling stave, cause landing in the slag particle temperature of discharge port 6 far below technique initialization value range;
In whole flushing cycles; at any time according to the feedback that proofing unit I 3 pairs of slag flow diameter of opening for feed 5 detect; to regulate pelletizer height; thus ensure that the slag particle temperature of discharge port 6 controls in the value range of technique initialization; and the slag particle temperature under every batch of landing is consistent substantially; the inter-adhesive one-tenth block of slag particle can not be caused, the temperature that subsequent technique needs can be reached simultaneously.

Another kind as embodiment one realizes the mode of outlet slag particle temperature control, described discharge port 6 is provided with the proofing unit II 4 for being granulated rear slag particle temperature sensing, and the height of pelletizer is regulated according to slag particle 8 temperature that it detects, to reach the temperature controlling discharge port 6 slag particle, thus slag particle 8 temperature out is consistent substantially; Described proofing unit II 4 is thermoelectricity occasionally infrared thermography, and in present case, proofing unit II 4 adopts thermopair.
Concrete principle of work is:
1), when the temperature value of the slag particle temperature that proofing unit II 4 detects discharge port 6 higher than technique initialization, swivel arrangement 21 is allowed to raise by setting device 22, make the impingement position of slag particle and cooling stave higher, to increase the duration of contact of slag particle on cooling stave, and then increase the cooling intensity of slag particle on cooling stave, thus reduce the slag particle temperature of discharge port 6;
2), when the temperature value of the slag particle temperature that proofing unit II 4 detects discharge port 6 lower than setting, swivel arrangement 21 is allowed to reduce by setting device 22, make the impingement position of slag particle and cooling stave lower, to reduce the duration of contact of slag particle on cooling stave, reduce the cooling intensity of slag particle on cooling stave, thus raise the slag particle temperature of discharge port 6;
In whole flushing cycles; at any time according to the proofing unit II 4 of discharge port 6 feedback to slag particle temperature detection after granulation; to regulate pelletizer height; thus ensure that the slag particle temperature of discharge port 6 controls in the value range of technique initialization; make the fluctuation of slag particle temperature out little; the stability of follow-up system operating mode can not be affected; and when slag particle temperature is too high; also be not easy to occur inter-adhesive one-tenth block; the phenomenons such as glass rate is on the low side; the advantages such as the working efficiency of its Whole Equipment is given full play to, and has simple to operate, reliable.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
