Further, referring to Figure 2 together to Fig. 4, one kind as semi-solid slurrying equipment provided by the invention is specific
Embodiment, sealing mechanism 21 include pedestal 211 and shield 212, and shield 212 can cooperate with pedestal 211, by soup ladle 26 seal every
Absolutely, shield 212 is detachably connected with pedestal 211, surrounds cavity between shield 212 and pedestal 211.It, can when shield 212 is opened
The soup ladle 26 for holding molten metal bath to be moved on pedestal 211 by conveying mechanism 30；Then, it is covered and is closed by shield 212
On pedestal 211, soup ladle 26 is sealed in cavity, allows for the air exclusion outside soup ladle 26 and cavity in this way.
Specifically, the first actuator 232 is motor, and the main body of motor is installed on 212 outside of shield, the top of shield 212
Equipped with seal assembly, sealed between the shaft and stirring rod 231 and shield 212 of motor by seal assembly.It can ensure in this way
When motor rotates, shield 212 is air tight, it is ensured that the sealing of cavity；It simultaneously can be using shield 212 to stirring rod 231 and motor
It radiates, prevents the excessively high failure of motor temperature or accident.It can be connected by gearbox between motor and stirring rod 231,
Motor speed is adjusted in this way, plays the role of controlling mixing speed.The seal assembly can be sleeve sealing structure etc..It is preferred that
Ground, the first actuator 232 are variable-frequency motor, in this way the revolving speed convenient for control stirring rod 231.
Specifically, shield 212 and pedestal 211 can be manufactured using alloy (such as steel, cast iron), can be ensured so higher
Intensity, avoid when vacuumizing shield 212 or pedestal 211 from deforming；It is preferable thermally conductive also to ensure that shield 212 has simultaneously
Performance.
Further, pedestal 211 is equipped with the seal washer cooperated with 212 open edge of shield.Sealing ring is arranged can
So that cavity has preferable sealing effect, gas leakage between shield 212 and pedestal 211 is prevented, the effect vacuumized is influenced.
Specifically, pedestal 211 is equipped with frame-shaped seal groove, and seal washer is placed in seal groove, can be avoided so close
Seal washer is mobile, prevents sealing structure from failing.Preferably, shield 212 is equipped with sealed groove, is embedded with sealing in sealed groove
Ring, in this way when shield 212 and the lid of pedestal 211 close, sealing ring and seal washer can play sealing function simultaneously, three-layer sealed
Structure, it is ensured that soup ladle 26 is isolated from the outside world by shield 212 with pedestal 211.
Further, please refer to figs. 2 and 3 together, and one kind as semi-solid slurrying equipment provided by the invention is specific
Embodiment, pedestal 211 are equipped with for driving shield 212 and pedestal 211 to cover the second actuator 27 for closing or opening.Using
Two actuators 27 drive shield 212 and pedestal 211 to open and close, and convenient for the control to shield 212, can prevent from being opened manually
Shield 212 is burned.
Further, referring to Figure 4 together and Fig. 5, specific as one kind of semi-solid slurrying equipment provided by the invention
Embodiment, vacuum device include and the vacuum tube 221 of cavity connection, the vacuum pump connecting with vacuum tube 221 and setting
Blow valve on shield 212.In shield 212 and 211 Gai Hehou of pedestal, the air in cavity is extracted out using vacuum pump, from
And the oxide isolations such as molten metal bath in soup ladle 26 and water, oxygen in air is avoided to react, it prevents from generating metal oxide,
Improve the purity of semi solid slurry.Installation of relief valve can convey gas into cavity after the completion of prepared by semi solid slurry,
The vacuum degree in cavity is reduced, convenient for separating shield 212 and pedestal 211, the semi solid slurry prepared is taken out spare.
Specifically, the second actuator 27 is motor or cylinder.Linear motor or lifting cylinder can be used, by second
The shell of actuator 27 is fixed on pedestal 211, and shield 212 is mounted on output shaft, and this makes it possible to pass through the second driving
The lifting of part 27 is so that the rise of shield 212 or fall.
Preferably, the second actuator 27 is the revolution clamping cylinder being vertically arranged on pedestal 211, so that shield
212 can not only go up and down along the vertical direction during opening or falling, additionally it is possible to be rotated along cylinder piston rod.Make in this way
Conveying mechanism 30 can be avoided by obtaining after shield 212 is opened, and shield 212 is avoided to generate interference to the movement of conveying mechanism 30.Specifically
Ground, revolution clamping cylinder moves along a straight line in first stroke, so that shield 212 rises, stirring rod 231 rises to soup ladle 26
Top；Revolution clamping cylinder is rotated in the second formation or screw, so that shield 212 deviates the upper of soup ladle 26
Side thus is avoided that shield 212 stirring rod 231 and soup ladle 26 during opening or falling generate interference, prevents in soup ladle 26
Semi solid slurry spill.
Further, the clamping device 25 for gripping soup ladle 26 is additionally provided on pedestal 211.Using clamping device
25, soup ladle 26 can be locked on pedestal 211, soup ladle 26 can be avoided to shake when rabbling mechanism 23 stirs in this way, can also prevented
Only in 212 lifting process of shield soup ladle 26 movement.It prevents from causing semi solid slurry to spill since soup ladle 26 shakes, causes safety
Accident.
Further, detent is provided on soup ladle 26, clamping device 25 includes and the briquetting 252 of clamping matching and use
In the third actuator 251 of driving briquetting 252.Passed through using briquetting 252 and clamping matching convenient for keeping the steady of soup ladle 26
