Here, a specific explanation of the internal passage of the stirring blade provided along the blade portion and the shaft portion is required. The paddle portion 331 of the stirring paddle is O-shaped or twisted O-shaped, the rotating shaft portion 332 of the stirring paddle is located at the upper side of the paddle portion and is connected with the paddle portion into a whole, and the inlet and the outlet of the inner channel 333 of the stirring paddle are arranged on the upper end face of the rotating shaft portion, so that the extending direction of the inner channel 33 of the stirring paddle is approximately as follows: enters from an inlet on the upper end surface of the rotating shaft part, then walks around the O-shaped paddle part for one circle, and finally exits from an outlet on the upper end surface of the rotating shaft part. Also, since the inlet and outlet of the inner channel of the stirring paddle are not positioned at the center of the upper end surface of the rotating shaft part, the inlet flow cavity and the outlet flow cavity of the stirring paddle are designed into annular cavities.

More specifically, the paddle inflow cavity 34 is located on the side between the inner and outer paddles, and the paddle outflow cavity 35 is located on the top between the inner and outer paddles; a third sealing ring structure 37 is arranged between the inner stirring paddle connector 32 and the outer stirring paddle connector 31 corresponding to the stirring paddle inflow cavity 34; a fourth sealing ring structure 38 is arranged between the inner joint 32, the outer joint 31 and the driving shaft 36 of the stirring paddle corresponding to the outflow cavity 35 of the stirring paddle.

The third sealing ring is correspondingly an annular sealing ring, and seals the stirring paddle inflow cavity to prevent leakage of cooling medium. The stirring paddle outflow cavity is a cavity formed by matching between the stirring paddle inner joint and the top of the stirring paddle outer joint, but because the stirring paddle driving shaft penetrates through the central positions of the stirring paddle inner joint and the stirring paddle outer joint (wherein the stirring paddle driving shaft and the stirring paddle inner joint are relatively fixed, but are relatively pivoted with the stirring paddle outer joint, and the stirring paddle inner joint and the stirring paddle outer joint are relatively pivoted), the stirring paddle outflow cavity is also an annular cavity, and correspondingly, the fourth sealing ring structure is a sealing ring sleeved on the stirring paddle driving shaft and positioned in the stirring paddle outflow cavity, so that the cooling medium in the stirring paddle outflow cavity is prevented from leaking from the matching gap between the stirring paddle driving shaft and the stirring paddle inner joint and the stirring paddle outer joint.

More specifically, the paddle drive shaft 36 is connected to the rotating shaft portion 332 of the paddle through the outer paddle fitting 31 and the inner paddle fitting 32, and drives the inner paddle fitting 32 and the paddle 33 to rotate. It should be noted that, the upper end surface of the rotating shaft portion 332 of the stirring paddle is connected to the lower end surface of the inner joint 32 of the stirring paddle, so that the inlet 334 and the outlet 335 of the inner passage of the stirring paddle are respectively communicated with the water inlet 321 and the water outlet 322 of the inner joint of the stirring paddle; meanwhile, the center position of the rotor shaft portion 332 of the paddle is correspondingly connected to the paddle drive shaft 36. That is, the paddle drive shaft 36 rotates while driving the paddle nipple 32 and the shaft portion 332 of the paddle to rotate, but the outer paddle nipple 31 remains relatively stationary, and because of the existence of the paddle inlet chamber 34 and the paddle outlet chamber 35, the cooling medium is always kept flowing along the inner paddle nipple inlet channel 311, the paddle inlet chamber 34, the inner paddle nipple inlet channel 321, the inner paddle channel 333, the inner paddle nipple outlet channel 322, the paddle outlet chamber 35, and the outer paddle nipple outlet channel 312.

In addition, the paddle drive shaft 36 is connected to the agitator drive spindle via a transmission mechanism such as a planetary gear set, thereby obtaining power, and the layout thereof varies for different types of agitators. These are conventional in the mixer art and will not be described in detail herein.

It should be mentioned that, besides a group of stirring paddle circulation cooling systems, more than two groups of stirring paddle circulation cooling systems can be arranged, so long as the stirring paddle circulation cooling systems are reasonably distributed, and then the circulation cooling outer total joint is provided with a circulation cooling outer total joint water inlet channel and a circulation cooling outer total joint water outlet channel, and the circulation cooling outer total joint water outlet channel is connected into the circulation cooling system through a pipeline.

As another alternative, the water inlet channel of the outer joint of the stirring blade and the water outlet channel of the outer joint of the stirring blade can be exchanged with each other, correspondingly, the water inlet channel of the inner joint of the stirring blade and the water outlet channel of the inner joint of the stirring blade are also exchanged with each other, and the inlet and the outlet of the inner channel of the stirring blade are also exchanged with each other, so that the cooling medium flows along the water inlet channel of the outer joint of the stirring blade, the water inlet channel of the inner joint of the stirring blade, the water outlet channel of the outflow cavity of the stirring blade and the water outlet channel of the outer joint of the stirring blade in turn. It is colloquially also possible to circulate the cooling medium in reverse. Is an equivalent alternative technical scheme.
