[0027] The stirring mechanism 14 includes a connecting block 143 fixedly connected to the outer wall of one side of the rotating rod 11, a second connecting groove 144 is opened on one side of the connecting block 143, and a stirring blade 142 is movably connected to the inner wall of the second connecting groove 144. The outer wall of one side of the stirring blade 142 is fixedly connected to a connecting column 141, and the connecting column 141 is correspondingly connected to the first connecting groove 12 opened on the outer wall of the rotating rod 11. The first spring 13 is arranged between the connecting column 141 and the first connecting groove 12. A slot 145 is opened on the outer wall of one side of the connecting block 143, and a clamping hole 145 is provided on one side of the slot It is connected to a clamping block 146, and a second spring 147 is movably connected to one side of the clamping block 146. The side of the second spring 147 away from the clamping block 146 is connected to a limiting block 148, and one side of the limiting block 148 is fixedly connected to a mounting block 149. The clamping block 146, the second spring 147 and the limiting block 148 are all arranged on one side of the inner wall of the mounting block 149, and one side of the mounting block 149 is correspondingly connected to the stirring blade 142. There are two connecting blocks 143, which are respectively arranged at the upper and lower ends of the stirring blade 142, and the clamping block 146 is slidably connected to the inner wall of one side of the mounting block 149.

[0028] By providing a motor 6, a rotating rod 11 is connected to the lower end of the motor 6, and a plurality of stirring mechanisms 14 are arranged in a circular array on the outer wall of the rotating rod 11, which can make the stirring more uniform and thus improve the stirring efficiency. A first connecting groove 12 is provided on the outer wall of the rotating rod 11, and the stirring mechanism 14 is correspondingly connected to the first connecting groove 12, and a first spring 13 is provided between the stirring mechanism 14 and the first connecting groove 12. Therefore, when the motor 6 is started, the motor 6 will drive the rotating rod 11 to rotate, and drive the stirring mechanism 14 to rotate, and then perform the stirring operation. However, after long-term use, the stirring blade 142 needs to be replaced, but the existing ones mostly adopt an integrated design, and the stirring blade 142 is fixedly connected to the rotating rod 11. Therefore, when maintenance and replacement are needed, the entire design needs to be replaced. The stirring mechanism 14 is provided with a connecting block 143, and the connecting block 143 is provided with two and is respectively fixedly connected to the outer wall of one side of the rotating rod 11, and a second connecting groove 144 is provided on the side corresponding to the two connecting blocks 143, and the inner wall of the second connecting groove 144 is slidably connected to the stirring blade 142, so that the stirring blade 142 can be limited and connected by the connecting block 143, and the outer wall of one side of the stirring blade 142 is fixedly connected with three connecting columns 141, and the three connecting columns 141 can be connected to the first connecting groove 12 provided on the outer wall of the rotating rod 11, so as to limit the position of the stirring blade 142 and connect to the inner wall of the first connecting groove 12 There is a first spring 13, which is arranged between the connecting column 141 and the first connecting groove 12. Therefore, when the stirring blade 142 is installed, the first spring 13 will be squeezed. At this time, by limiting the stirring blade 142, a pressure is continuously applied to the first spring 13. When the limit of the stirring blade 142 is cancelled, the first spring 13 will generate a reaction force on the stirring blade 142, which can quickly pop out the stirring blade 142, thereby realizing the operation of quick disassembly and replacement. For limiting the stirring blade 142, the inner wall of the second connecting groove 144 opened on the side wall of the connecting block 143 is connected to the mounting block 149, and the inner wall of the mounting block 149 is connected to the clamping block 146, the second spring 147 and the limiting block 148. The clamping block 146 can be clamped with the slot 145 opened in the connecting block 143, so that the mounting block 149 can be fixed to one side of the inner wall of the connecting block 143, thereby limiting the stirring blade 142. When the stirring blade 142 needs to be disassembled, since there is a convex plate on one side of the clamping block 146 for the staff to press, the convex plate on one side of the clamping block 146 can be squeezed with both hands at the same time. At this time, the clamping block 146 will squeeze the second spring 147. At this time, the clamping block 146 will shrink into the mounting block 149 and leave the slot 145 and the connecting block 143. Then the mounting block 149 can be taken out. At this time, the stirring blade 142 will be subjected to the reaction force of the first spring 13, which will pop it out, thereby realizing the quick disassembly and replacement operation of the stirring blade 142.

[0030] It should be noted that a shaft seal 5 is connected to the lower end of the motor 6, and the shaft seal 5 can ensure that there will be no gap at the connection between the rotating rod 11 and the box body 1, and then liquid leakage will occur. The observation device 2, monitoring instrument 3 and air pressure instrument 4 connected to the upper end of the box body 1 can enable the staff to quickly connect to the situation inside the box body 1 and then adjust it at any time. The side wall of the box body 1 is connected to a liquid discharge pipe 7 and a liquid inlet pipe 8, which can transport the liquid into the inner wall of the box body 1 and output it. There are five brackets 9 in a circular array on the outer wall of the box body 1, which can be used for fixed installation of the box body 1. The bottom end of the box body 1 is connected to a material discharge port 10, which can discharge the stirred material.

[0031] The working principle of the above embodiment is as follows: the material and liquid are transported into the box body 1, and the motor 6 is started at this time. The motor 6 will drive the rotating rod 11 to rotate, and drive the stirring mechanism 14 to rotate, and then perform the stirring operation. However, after a long period of use, the stirring blade 142 needs to be replaced. However, the existing ones mostly adopt an integrated design, and the stirring blade 142 is fixedly connected to the rotating rod 11. Therefore, when it needs to be repaired and replaced, it needs to be disassembled and replaced as a whole, which increases the cost and makes the operation more cumbersome. For this purpose, the stirring blade 142 can be connected to the first connecting groove 12 opened on the outer wall of the rotating rod 11, and connected to the second connecting groove 144 opened on the side wall of the connecting block 143 fixedly connected to the outer wall of the rotating rod 11. At this time, the connecting column 141 on one side of the stirring blade 142 will It is engaged with the first connecting groove 12 and squeezes the first spring 13. At this time, the mounting block 149 is installed in the second connecting groove 144 opened in the connecting block 143. At this time, the block 146 is engaged with the slot 145 opened on the connecting block 143, and the stirring blade 142 can be fixedly connected. When the stirring blade 142 needs to be disassembled and replaced, the staff can squeeze the convex plate on one side of the block 146 with both hands at the same time. At this time, the block 146 will squeeze the second spring 147. At this time, the block 146 will shrink into the mounting block 149 and leave the slot 145 and the connecting block 143, and then the mounting block 149 can be taken out. At this time, the stirring blade 142 will be subjected to the reaction force of the first spring 13, and it will be popped out, thereby realizing the quick disassembly and replacement operation of the stirring blade 142.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
