Solidification forms particle.
The lava of final granule shape enters in inner cylinder 43 from discharge bucket 22 into particle entrance 41 is crossed, the driving of the second actuator 13
The rotation of second roller 4, lava particle move downward under the action of helical blade 9 along inner cylinder 43, finally from cooling material outlet 48
It drops out.And liquid metal second pump 8 under the action of by cooling duct 44, cool down to the lava particle in inner cylinder 43,
So the temperature of the lava particle finally dropped out from cooling material outlet 48 is lower.
The high temperature fluent metal being discharged from cooling chamber 33 is introduced into the first liquid reserve tank 16, and it is cold to enter back into First Heat Exchanger
But, it is finally recirculated by the first pump.From cooling duct 44 be discharged high temperature fluent metal successively pass through the second liquid reserve tank 19,
Second heat exchanger 17 is cooled, finally recirculates by the second pump 8.When the pump of restarting first and the second pump 8, first open
Heating rod 84, heating rod 84 heat the liquid metal in pipeline, and the liquid metal of solidification is made to become liquid again, restore
Mobility turns off heating rod 84.
Embodiment 2
On the basis of embodiment 1, as shown in Figure 7 and Figure 8, the shaft 6 on 2 right side of heat exchange box is located in this programme and is located at
45 periphery of rotation axis on 42 right side of outer cylinder is all provided with limited position mechanism, avoids shaft 6 and rotation axis 45 that axial play occurs.
By taking shaft 6 as an example, position-limit mechanism includes the fixed block 18 positioned at 16 left side of the first liquid reserve tank, fixed block 18 and first
16 left wall of liquid reserve tank is integrally formed.Fixed block 18 is ring-type, and shaft 6 first protrudes into after 18 inner circumferential of fixed block again through the first liquid reserve tank

Road, three screw channels are aligned with three limiting slots respectively, and are set there are three the threaded rod 53 being threadedly engaged with screw channel, will
After threaded rod 53 screws in screw channel, 53 end of threaded rod is protruded into limiting slot, pushes against change 5, is played support to shaft 6 and is made
With while, also avoid shaft 6 that axial float occurs during rotation.
After threaded rod 53 pushes against change 5, change 5 can not be rotated relative to threaded rod 53, therefore when shaft 6 rotates, change 5
It is rotated relative to shaft 6, ball 52 rolls between change 5 and shaft 6, the friction that ball 52 reduces change 5 and shaft 6 is subject to
Power avoids change 5 and shaft 6 from wearing.Secondly, ball 52 plays a supporting role to change 5, avoid change 5 in threaded rod 53
Pressure effect is lower, and deformation occurs.
6 outer wall of shaft is painted coated with high temperature resistant, and the present embodiment is painted using inorganic silicon high temperature resistant, high temperature resistant paint solidification
Oil resistant paint layer is formed afterwards.It is fixed with thermal insulation layer outside high-temperature-resistant layer, the thermal insulation layer in the present embodiment uses asbestos layer, avoids work
People is burned after touching shaft 6.
