Moreover, the male screw portion 62 engraved on the cap nut 36 is screwed into the female screw portion 60 engraved on the nut mounting hole 57 of the outer cylinder 15, whereby the verticality of the stirring pin 7 is easily obtained. In addition, since the cap nut 36 and the outer cylinder 15 have a sealing function, even if the welded portion 34 provided on the outer surface side of the outer cylinder 15 is worn, the space between the cap nut 36 and the outer cylinder 15 is reduced. It is easy to maintain the sealing property of. In addition, since the screw-threaded portion is resin-impregnated, there is no risk of leakage of cooling water in the jacket.

Further, in the stirring pin 7 of this embodiment, since the pin body 44 made of cemented carbide is fixed to the stud bolt 42 by brazing, the spring pin insertion hole which causes stress concentration is formed in the pin body 44. Eliminates the need to equip. Moreover, as shown in FIG. 1, if the molten metal 50 used for brazing fills the gap S between the pin body 44 and the stud bolt 42, the impact due to the collision with the ball in the fixed container 3 or the material to be processed is achieved. Therefore, it is possible to prevent the rattling between the pin body 44 and the stud bolt 42. Therefore, the risk of cracks occurring in the cemented carbide pin body 44 due to stress concentration is avoided, thereby allowing the cemented carbide pin body 44 to reach its original life due to wear and to improve the reliability of the design life. It can be further increased.

Incidentally, it goes without saying that the configurations of the cap nut member and the agitation pin in the dispersing machine of the present invention are not limited to the configurations of the above-mentioned embodiment, and various forms can be adopted. Further, the form of the disperser of the present invention is not limited to the horizontal sand grinder of the present embodiment, but can be applied to other forms of dispersers such as a vertical sand grinder.

As described above, according to the dispersing machine of the present invention, the stirring pin projecting on the outer peripheral surface of the agitator shaft has the skirt portion of the cemented carbide pin body capped on the stud bolt. Since the stud bolt is mounted in a cap nut member that stands upright, the stud bolt is not attached even if the outer peripheral surface of the agitator shaft is worn due to friction with the balls or the material to be processed loaded in the fixed container. The state of being covered with the pin body made of cemented carbide is maintained, and part of the stud bolt is not exposed in the space for dispersing and kneading the material to be treated. Therefore, it is possible to prevent the inconvenience of wear breakage of the stud bolts from occurring before the outer peripheral surface of the agitator shaft reaches the end of its life due to wear, and a disperser equipped with a stirring pin that can be continuously used for a longer period of time. Can be provided.
