[0033] In this embodiment, the water inlet structure 9 includes a water pump 91 mounted on the upper side of the mounting frame 101, the water inlet end of the water pump 91 is connected to the water inlet pipe 90, and the water outlet end is connected to the soft water pipe 92. The L-shaped water pipe 93 is installed inside the cylinder body 1, the flange of the L-shaped water pipe 93 is connected with the pipe joint 604, and the top of the L-shaped water pipe 93 slides through the upper side of the cylinder body 1 and is connected with the soft water pipe 92. Each branch pipe 602 is connected and installed with a nozzle 603 on the lower side, the nozzle 603 is located above the stirring rod 52 and the filter plate 53, a circular cavity is formed in the hollow support ring 601, the circular cavity is communicated with the pipe cavity of each branch pipe 602, and a pipe joint 604 is formed on one side of the hollow support ring 601, which is communicated with the circular cavity. The guide rod 71 is installed in the inner side of the cylinder body 1 in a ring shape, the branch pipe 602 is slidably sleeved on the guide rod 71 through the connecting pipe 61, and the heating rod 711 is embedded and installed in the inner side of the guide rod 71. The heating rod 711 can be heated during mixing, so as to promote the mixing of the additive. Therefore, the water pump 91 is connected with the mixed liquid or cleaning liquid through the water inlet pipe 90, and sends the mixed liquid or cleaning liquid into the hollow support ring 601 and each branch pipe 602, and sprays downward through each nozzle 603. During the stirring process, the mixed liquid can be widely distributed and mixed with the additive liquid in the cylinder body. During the later cleaning process, the cleaning liquid can directly flush the stirring rod 52 and the filter plate 53.
[0034] More specifically, in use, the additive liquid material to be mixed is poured into the hopper 3, at this time the rotating motor 45 drives the polygonal rotating pipe 4 to rotate clockwise in the forward direction, which drives the rotating pipe 51 of the stirring frame 5, the stirring rod 52, and the filter plate 53 to rotate clockwise in the forward direction, thereby mixing and stirring the material in the cylinder body 1. At this time, the lifting screw 402 is rotated clockwise in the forward direction under the action of the polygonal slide block 403 and the polygonal cavity 401. Since the transmission screw pipe 85 is threadedly sleeved on the lifting screw 402, the driving motor 81 drives the driving gear 84 to rotate counterclockwise through the rotating shaft 82, so that the driving gear 84 meshes with the driven gear 86 of the transmission screw pipe 85 to rotate clockwise, that is, the transmission screw pipe 85 rotates clockwise synchronously with the lifting screw 402. At this time, the lifting screw 402 does not slide under the action of the threaded transmission structure, but the rotating shaft 82 drives the rotating screw 7 to rotate counterclockwise synchronously through the transmission belt 83. The rotating screw 7 can threadedly drive the connecting pipe 61 on one side of the upper support 6 and the lower support 60 to displace upward along the guide rod 71, so as to displace the upper support 6 and the lower support 60 upward synchronously and limit the stirring frame 5 rotating in the forward direction, thereby improving the stirring height.
[0035] With the same principle, after the stirring frame 5 reaches the top, the transmission motor 81 drives the rotating shaft 82 to rotate clockwise in the forward direction. At this time, not only can it drive the stirring frame 5 to move downward, thereby forming the upward and downward reciprocating stirring frame 5 movement to expand the mixing range, but also the driving gear 84 rotates clockwise in the forward direction, engaging the driven gear 86 and the transmission screw pipe 85 to rotate counterclockwise. At this time, the transmission screw pipe 85 and the lifting screw 402 have different rotation directions, and the lifting screw 402 can be pushed upward and displaced along the polygonal cavity 401 under the threaded transmission action of the transmission screw pipe 85, and the piston 404 is driven to move upward, so that the liquid at the bottom of the cylinder is sucked into the polygonal cavity 401 from the side water injection hole 43 and the upper water injection hole 44 of the inner disc cavity 42, and under the condition of cylinder 1 sealing, the air outside the cylinder 1 enters to increase the air pressure when the stirring frame 5 reaches the bottom. When the stirring frame 5 reaches the bottom, the transmission motor 81 drives the driving gear 84 to rotate counterclockwise and engages the driven gear 86 and the transmission screw pipe 85 to rotate clockwise, and the rotating motor 45 drives the polygonal rotating pipe 4 and the lifting screw 402 to rotate counterclockwise at this time. Under the condition that the transmission screw pipe 85 rotates clockwise, the lifting screw 402 can be displaced downward and drive the piston 404 to push the liquid in the polygonal cavity 401 downward, so that the liquid enters the inner disc cavity 42 through the through hole 405, and is sprayed to the four sides and the upper side by each side water injection hole 43 and upper water injection hole 44., improve the different flow paths and flow rates, and fully mix and collide with the liquid inside the cylinder 1, and the upwardly sprayed liquid can flow towards the stirring frame 5, thereby retransporting the liquid deposited at the bottom of the cylinder upward, synchronously mixing with the stirring frame 5, and sequentially operating, which can greatly improve the blending effect of the additive;
[0036] During mixing, the three guide rods 71 can simultaneously conduct heat to the upper bracket 6 and the lower bracket 60 to heat the liquid in the cylinder 1, and when additional mixing liquid needs to be added into the cylinder 1, the water pump 91 and the water inlet pipe 90 of the water inlet structure 9 can be used to sequentially draw the external mixing liquid into the soft water pipe 92, the cavity of the hollow support ring 601, and the cavities of the four branch pipes 602, and finally sprayed downward by the ten nozzles 603 at the lower side of the branch pipe 602, and the sprayed mixing liquid can be mixed with the additive in the cylinder 1 in a large range and fully;
[0037] After the mixing, the additive solution can be discharged outward by opening the discharge valve pipe 2, and because the liquid level inside the cylinder 1 rises after the water spraying base 41 sprays the liquid, the air pressure inside the cylinder 1 is enhanced at this time, which helps to improve the discharge efficiency of the liquid from the discharge valve pipe 2, and after the solution is discharged, the mixed liquid of the water inlet structure 9 can be replaced with cleaning liquid, which is sent into each nozzle 603 to be sprayed downward, so as to quickly flush the rotating stirring rod 52 and the filter plate 53 below, thereby improving the cleaning efficiency and effect of the stirring frame 5.

Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
