Specifically to introduce this utility model below by following examples and to improve metallurgical cinder dry granulation device
The operating process of energy.
Embodiment one：
As shown in Fig. 1-2,5, because the flight speed of slag particle and the rotating speed of revolving cup are related, rotational speed of rotor then slag particle flight slowly
Speed is relatively low, and it is higher, so, if slag particle only keeps constant speed to clash into is subject to slag cavity slag particle that revolving cup turns fast then slag particle flight speed
During impingement region wall, because of the same position of excessive slag particle this internal face of constant impingement, easily cause slag particle on this internal face
Bonding and hardened in bulk, therefore, this embodiment is characterized in that the rotating speed of revolving cup non-constant.Specifically, the system is to utilize
The rotating speed of revolving cup carries out slag granulating in time according to cyclically-varying, including as follows step by step：First, collect revolving cup
Little rotating speed and maximum (top) speed, and this two kinds of rotating speeds are stored in controller；Then, provide rotating speed by frequency conversion motor for revolving cup,
And controlled via the rotating speed that frequency conversion motor is supplied to revolving cup by controller and enter line period between minimum speed and maximum (top) speed

Can also comply with triangle (as b in Fig. 2) or trapezoidal (as c in Fig. 2) rule；And this periodically variable cycle time is 8 seconds,
Certainly cycle time described in different enforcement can be also the other values in the range of 1,3,5,10 etc. 1～10.Due to turning of revolving cup
Speed is in cyclically-varying, result in the change of the slag particle horizontal direction flight speed that different time throws away, and slag particle was flying
Only acted on by gravity and air drag in journey, the change of horizontal component velocity will lead to slag particle and by slag cavity slag particle impingement region wall
The time of face contact impact simultaneously differs.The i.e. slag particle different flight time, lead to the drop in its action of gravity
Different.So slag particle, in the contact point by slag cavity slag particle impingement region wall, occurs as well as the rotation speed change of revolving cup
Periodically change, thus defining one to clash into band than relatively decentralized.So because the rum point of slag particle more disperses, just do not allow
Easily there is bonding and the caked phenomenon of plate.
Embodiment two：
As in Figure 3-5, because slag particle bonding is relevant with the effective area clashing into by slag cavity slag particle impingement region wall,
It is typically with water-cooling structure by the slag cavity slag particle impingement region wall first half, slag particle is clashed into by slag cavity slag particle in shock
Certain cooling effect will be obtained after the wall of region, so, if slag particle clashes into just for the internal face at a position, slag particle
Temperature reduces relatively slowly, easily causes slag particle to bond on this internal face and hardened in bulk, therefore, this embodiment is characterized in that being subject to slag
The vertical height position of cavity is simultaneously non-constant.Specifically, the system be using by slag cavity vertical height position in time by
Carry out slag granulating according to cyclically-varying, including as follows step by step：First, collect by slag cavity in vertical direction minimum
Position and highest order, and this two kinds of extreme positions are stored in controller；Then, reciprocal to being provided by slag cavity from Electrohydraulic push rod
Lifting drive, and controlled in lowest order via the vertical height position that Electrohydraulic push rod is supplied to by slag cavity by controller and
Carry out cyclically-varying, this periodically variable curve meets sinusoidal rule, as shown in a in Fig. 4, certainly in difference between a high position
Curve described in embodiment can also comply with triangle (as b in Fig. 4) or trapezoidal (as c in Fig. 4) rule；And this cyclically-varying
Cycle time be 8 seconds, cycle time described in different enforcement can be also the other in the range of 1,3,5,10 etc. 1～10 certainly
Value.Because the vertical height position by slag cavity is in cyclically-varying, result in the slag particle that different time throws away in the horizontal direction
After flying out, slag particle will be led to the position by slag cavity slag particle impingement region wall contact impact and to differ, that is, slag particle is being subject to
Different impingement positions are obtained on slag cavity.So slag particle is in the contact point by slag cavity slag particle impingement region wall, also can be with
The changing of generating period by the vertical height position change of slag cavity, thus defining one to clash into band than relatively decentralized.
So because the rum point of slag particle more disperses, just it is less likely to occur bonding and the caked phenomenon of plate.
Embodiment three：
The present embodiment be by both modes of embodiment one and embodiment two in combination with together with, allow revolving cup 2 simultaneously
Rotating speed and by slag cavity 1 vertical height position all non-constant, specifically just do not repeating.In this way can also
Slag particle is made to obtain different impingement positions on by slag cavity, so slag particle is being contacted by slag cavity slag particle impingement region wall
Point, the rotating speed as well as revolving cup and the changing, thus being formed of generating period by the vertical height position change of slag cavity
One clashes into band than relatively decentralized.So because the rum point of slag particle more disperses, just it is less likely to occur bonding and hardened in bulk
Phenomenon.
In above three embodiment, described system can also be obtained by temperature measuring equipment and be subject to slag cavity 1 slag particle impingement region
Temperature, and according to the temperature by slag cavity 1 slag particle impingement region obtaining to the rotating speed of described revolving cup 2 and or be subject to slag cavity 1
Vertical height position adjusted control further according to cyclically-varying in time.So, slag can be made by by slag chamber
