The support 51 is arranged on the granulation tank 400.

[0073] Specifically, as shown in Figures 1 to 6 The upper adjusting piece 48 is arranged above, the lower adjusting piece 50 is arranged below, the lower adjusting piece 50 is provided with adjusting holes arranged at equal intervals in the up-down direction, the upper adjusting piece 48 is provided with at least one connecting hole, the connecting piece 49 passes through the connecting hole of the upper adjusting piece 48 and the adjusting hole of one of the lower adjusting pieces 50 to connect the upper adjusting piece 48 and the lower adjusting piece 50, the size of the upper adjusting piece 48 and the lower adjusting piece 50 in the up-down direction after connection can be changed by connecting different adjusting holes, the size of the whole inclination adjustment component 41 in the up-down direction is changed, and then the adjustment seat 1 is adjusted to rotate to drive the dispersing rod 21 to rotate in the up-down direction, and the angle between the dispersing rod 21 and the ground is changed.

[0074] The molten metal granulation and dispersing device 200 of the embodiment of the utility model, through setting up upper adjusting piece 48, connecting piece 49, lower adjusting piece 50 and support 51, screw sleeve 47 and upper and lower screw rod 46 are all threadedly connected, the size of the whole inclination adjustment component 41 in the up-down direction can be coarsely adjusted by rotating the screw sleeve 47, then the size of the whole inclination adjustment component 41 in the up-down direction is finely adjusted by upper screw rod 45, lower screw rod 46 and screw sleeve 47, so that the liquid column 500 vertically impacts the dispersing rod 21, and the stability of the dispersing device 200 is improved.

[0075] When adjusting the dispersing rod 21, the locking nut connecting the adjusting seat 1 and the crankshaft 42 is loosened at this time, so that the crankshaft 42 can normally deflect; at the same time, the locking nut of the screw buckle is loosened, so that the screw rod 45 on the screw buckle can normally rotate. The plane passing through the center line of the screw buckle connecting pin and perpendicular to the center line of the screw rod of the screw buckle is recorded as the first plane, and the plane passing through the center line of the hole of the sleeve 43 connecting the ear 44 and perpendicular to the center line of the crankshaft 42 (second shaft 422) is recorded as the second plane. As the adjusting seat 1 moves in the axial direction of the rotating shaft 32, the crankshaft 42 drives the sleeve 43 to make a spatial motion, and the second plane also changes in the spatial range, and the second plane has a unique intersection with the first plane, forming a spatial hinge connection pair with the rotating shaft 32 as the intersection. At this time, the movement mechanism composed of the hand wheel and the screw buckle has only one degree of freedom. The screw buckle, the upper adjusting piece 48, and the lower adjusting piece 50 all bear tension, and the hinge rotary pair connected by the three can not work when the hand wheel is adjusted, and the three can be regarded as a whole, that is, the entire granulation and dispersion device 200 can also be regarded as having only one degree of freedom at this time. Rotating the hand wheel drives the rotating shaft 32 to rotate, which drives the adjusting seat 1 to move in the axial direction of the rotating shaft 32 through the threaded pair, so that the dispersing rod 21 is re-centered with the liquid column 500, and at the same time, the crankshaft 42 drives the sleeve 43 to deflect, the sleeve 43 drives the upper screw rod 45 of the screw buckle to rotate through the spatial hinge connection pair, the locking nut connecting the adjusting seat 1 and the crankshaft 42 is tightened, and the locking nuts of the upper and lower screw rods of the screw buckle are tightened, forming a stable state under stress, and the adjustment is completed.

[0076] In some embodiments, the rotation angle of the dispersing assembly 2 is 0°-45°. Further, the rotation angle of the dispersing rod 21 relative to the ground, i.e., the horizontal plane, is set to avoid excessive rotation of the dispersing member. For example, taking the rotating shaft 32 and the adjusting seat 1 as the fulcrum, the dispersing assembly 2 is arranged at the left end of the fulcrum, and the inclination adjustment assembly 4 is arranged at the right end of the fulcrum. This layout allows the inclination angle of the dispersing assembly 2 to be changed by adjusting the size of the inclination adjustment assembly 4 in the up-down direction, thereby controlling the rotation range. When the inclination adjustment assembly 4 is operated, it will affect the inclination angle of the dispersing assembly 2 through the lever principle, but due to the existence of the fulcrum, the change of the inclination angle is limited within a safe range, i.e., 0° to 45°. By limiting the rotation angle of the dispersing member, it can prevent it from losing stability due to excessive inclination during operation, thereby ensuring the overall stability of the equipment. Limiting the rotation angle of the dispersing member can also prevent the operator from being injured due to the out-of-control equipment during operation, thereby improving the safety of the equipment. The plane formed by the front-back direction and the left-right direction is the horizontal plane.

[0077] In some embodiments, the outer thread of the rotating shaft 32 is trapezoidal thread, compared with the existing triangular thread, the trapezoidal thread can move a farther distance in the front-back direction after the rotating shaft 32 rotates one circle, and the adjustment efficiency is improved. Meanwhile, the tooth profile of the trapezoidal thread is wider and the tooth side angle is smaller, which makes the contact area between the tooth sides larger when the trapezoidal thread is subjected to axial force, thereby dispersing the pressure and improving the carrying capacity of the threaded connection.
