The rotating end of the rotating base 3 is fixed with the preparation frame 4, the left side of the top of the rotating base 3 is fixed with the first mounting frame 1, and the right side of the top of the rotating base 3 is fixed with the second mounting frame 2. The stirring component 5 is fixed to the top wall of the first mounting frame 1, and the stirring end of the stirring component 5 is located in the preparation frame 4. The stirring component 5 is connected to the gear 8 through the transmission component 6. The outer wall of the stirring frame is fixedly sleeved with a gear ring 7, and the gear ring 7 is meshed with the gear 8. A part of the position adjustment member 9 is arranged on the second mounting frame 2, and the other part of the position adjustment member 9 is fixed to the rotating end of the stirring component 5. The stirring plate 10 is fixed to the adjustment end of the position adjustment member 9 and is located inside the preparation frame 4. A row of pipes is fixedly connected to the lower side wall of the preparation frame 4. The mixing uniformity of the treatment agent affects the subsequent treatment effect. The liquid in the preparation frame 4 is stirred and mixed by the stirring assembly 5. At the same time, the stirring assembly 5 is driven by the transmission assembly 6 to drive the gear 8 to rotate, so that the ring gear 7 rotates in the opposite direction, and drives the preparation frame 4 to rotate in the opposite direction. By setting the preparation frame 4 that rotates in the opposite direction of the stirring assembly 5, in cooperation with the stirring assembly 5, the stirring and mixing effect and efficiency are further improved. While the stirring assembly 5 rotates, the position adjustment member performs a position adjustment action, drives the stirring plate 10 to adjust the position, and cooperates with the rotating configuration frame to achieve the stirring of the liquid while changing the stirring position of the stirring plate 10, so that the stirring is more comprehensive, thorough and efficient. In this way, through the linkage of the stirring assembly 5 and each structure, only one power output is needed to realize a variety of stirring and mixing methods such as fixed position stirring, rotation of the preparation frame 4, and position change stirring, which greatly improves the stirring and mixing efficiency and mixing uniformity.

[0046] Wherein, the stirring assembly 5 includes a motor 51, a first rotating shaft 52, a first bearing seat 53, a first stirring blade 54, and a second stirring blade 55.

The lower part of the first rotating shaft 52 passes through the first bearing seat 53 and the second mounting frame 2, and extends to the inside of the configuration frame 4, where a plurality of first stirring blades 54 are fixed. The bottom end of the first rotating shaft 52 is fixed with a second stirring blade 55, and the second stirring blade 55 is located below the first stirring blade 54. The length of the second stirring blade 55 is 2-4 times the length of the first stirring blade 54. The specific multiple is set as required. The motor 51 rotates, driving the first rotating shaft 52 to rotate, so that the first stirring blade 54 and the second stirring blade 55 rotate to perform stirring and mixing. The second stirring blade 55 disposed below the first stirring blade 54 performs large-scale stirring and mixing at the bottom of the preparation frame 4. Combined with the shorter first stirring blade 54 and the position-adjustable stirring plate 10, the liquid is stirred and mixed in different forms at different positions, and the mixing is more comprehensive and thorough.

[0047] Among them, the position adjustment member 9 includes a beveled cylinder 91, a spring 92, a sphere 93, and a vertical rod 94. The beveled cylinder 91 is fixed to the first rotating shaft 52.

The first rotating shaft 52 rotates, driving the inclined cylinder 91 to rotate. Due to the setting of the spring 92, the ball 93 always contacts the inclined surface of the inclined cylinder 91. During the rotation of the inclined cylinder 91, the ball 93 repeatedly moves up and down, driving the repeated up and down movement, and then driving the stirring plate 10 to repeatedly move up and down. Combined with the setting of the rotating preparation frame 4, repeated stirring and mixing operations are achieved at different positions of the liquid. In addition, the setting of the vertical rods 94 on the left and right sides of the first bearing seat 53, combined with the cooperation of the ball 93 and the inclined cylinder 91, during the rotation of the inclined cylinder 91, the vertical rods 94 on the left and right sides maintain an up and down movement trajectory, and the mixing effect is better.

Through the way of air flow stirring, the stirring and mixing of the liquid is achieved in another way, so that the treatment agent is mixed more evenly and the mixing efficiency is higher. The pumping process does not require an additional power source, and is linked with the vertical rod 94 to adjust the up and down position of the stirring plate 10 while also supplying air, which is a clever design. The first one-way valve 15 is set so that air can only enter the cylinder body 12 from the outside through the air inlet pipe 14, and the second one-way valve 17 is set so that the air in the cylinder body 12 can only be discharged through the air outlet pipe 16.
