However, during the charging process, the metal lifting rod is easily melted by heating or extends into the silicon liquid, so that the silicon material is scrapped.
Therefore, how to provide a lifting rod which avoids polluting silicon liquid is a technical problem which needs to be solved by the technical personnel in the field at present.
SUMMERY OF THE UTILITY MODEL
In view of the above, an object of the present invention is to provide a lifting rod, which can effectively prevent the lower end of the lifting rod from melting and polluting silicon liquid, and another object of the present invention is to provide a feeder comprising the lifting rod.
In order to achieve the above object, the utility model provides a following technical scheme:
a lift bar, comprising: the upper end of the molybdenum alloy rod body is connected with the lower end of the upper rod body.
Preferably, the upper rod body is detachably connected with the molybdenum alloy rod body.
Preferably, the upper rod body and the molybdenum alloy rod body are in threaded connection.
Preferably, the lower extreme of going up the body of rod is equipped with the external screw thread, the upper end of the molybdenum alloy body of rod be equipped with external screw thread complex screw hole.
Preferably, the lower extreme of going up the body of rod is equipped with the screw hole, the upper end of molybdenum alloy body of rod be equipped with screw hole complex external screw thread.
Preferably, the upper rod body is a stainless steel rod body.
A feeder comprising a lifting bar as claimed in any one of the preceding claims.
Compared with the prior art, the technical scheme has the following advantages:
the utility model provides a charging means and lifting rod thereof, include: go up the body of rod and the molybdenum alloy body of rod, the upper end of the molybdenum alloy body of rod is connected with the lower extreme of last body of rod. Because the lower extreme of lifter bar is close to the silicon liquid, through the high temperature resistant and the high melting point nature that utilize the molybdenum alloy, can guarantee that the lower extreme of lifter bar can not melt even stretching into in the silicon liquid yet, consequently can avoid the lifter bar lower extreme to melt and pollute the problem appearance of silicon liquid, and then reduce the extra manufacturing cost who brings because of the lifter bar.
