Detailed Description

The accompanying drawings are preferred embodiments of the large-angle rotary agitator, and the present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, 2, 3 and 4, the large-angle rotary stirrer comprises a motor 1, a transmission shaft 2, blades 3, a guide ring 4, a fixed cylinder 5 and a fixed rod 6.

The output shaft of the motor 1 is downwards fixedly connected with the upper end of the transmission shaft 2, and a lower end block 21 is arranged below the transmission shaft 2. The two blades 3 are symmetrically arranged on two sides of the lower end block 21, a rotating shaft 32 is arranged in the middle of the end surface of the blade 3 facing the lower end block 21, the rotating shaft 32 is inserted into the lower end block 21, and the blade 3 can rotate around the axis of the rotating shaft 32. The end surface of the vane 3 facing away from the lower end block 21 is provided with a cylindrical guide block 31,

the fixed cylinder 5 is sleeved above the transmission shaft 2. The cylindrical limiting block 22 is sleeved on the circumferential surface of the transmission shaft 2 inside the fixed cylinder 5, the limiting block 22 is fixedly connected with the transmission shaft 2, and the limiting block 22 is rotatably arranged in the inner wall of the fixed cylinder 5. The limiting block 22 ensures that the transmission shaft 2 can only rotate and cannot move up and down.

The guide ring 4 is sleeved outside the blades 3, and the two blades 3 are both positioned in the middle of the guide ring 4. As shown in fig. 5, the guide ring 4 includes an upper circular ring and a lower circular ring, the middle of the two circular rings is supported by a plurality of supporting frames 43, the supporting frames 43 are surrounded by arc-shaped bands 41, and the arc-shaped bands 41 are connected end to end. The inner side end surface of the arc-shaped belt 41 is internally provided with a guide groove 411, the lowest point and the highest point of the guide groove 411 are respectively positioned at two sides of the transmission shaft 2, two middle points of the guide groove 411 are positioned at two sides of the lowest point and the highest point, and a connecting line between the two middle points of the guide groove 411 is vertical to a connecting line between the lowest point and the highest point of the guide groove 411. The guide block 31 is slidably disposed in the guide slot 411. Gaps are reserved among the upper circular ring, the lower circular ring, the supporting frame 43 and the arc-shaped belt 41, and the gaps are material through holes 42. The material passing hole 42 allows the stirred material in the reaction kettle to freely pass through and out of the guide ring 4.

The fixed cylinder 5 and the guide ring 4 are connected with 3-8 fixed rods 6, 3-8 fixed rods 6 are distributed in a circular array around the axis of the transmission shaft 2.

When the device is used, the fixed cylinder 5 is fixed in the middle of the upper cover of the reaction kettle, and the motor 1 is positioned outside the reaction kettle. The power line of the motor 1 is connected with the power supply line of a factory, the motor 1 drives the transmission shaft 2 to rotate, and the lower end block 21 drives the blades 3 to rotate around the axis of the transmission shaft 2.
