In addition, after the traditional equipment completes the storage work, buffer still remains on the inner wall of the tank body. Therefore, when placing the next batch of buffer, the residual liquid is likely to contaminate the next batch of buffer. Utility Model Content

[0037] The outer wall at the top of the fixed ring 8 is rotatably connected to the inner wall at the bottom of the inner tube 7. The inner tube 7 and the outer tube 2 are connected through the fixed ring 8, so that the liquid in the inner tube 7 can enter the water outlet pipe 9 through the fixed ring 8. The bottom of the fixed ring 8 is fixedly connected to the water outlet pipe 9, and the inner wall of the inner tube 7 is fixedly connected to the blades 10, and the blades 10 are arranged in a circular array along the central axis of the inner tube 7.

[0038] The spray mechanism 6 includes a water drain box 61, the outer wall of the water drain box 61 is fixedly connected to a water inlet pipe 62, the bottom of the water inlet pipe 62 is fixedly connected to a fixed frame 63, and the inner wall of the fixed frame 63 is fixedly connected to a blocking cone 64.

[0039] Working principle:

[0040] When in use, first place the frame 1 on the ground, and use the frame 1 to stabilize the position of the outer cylinder 2. After the position of the outer cylinder 2 is stabilized, then flip the upper cover 11 upwards. After the upper cover 11 is flipped upwards, the buffer can be poured into the storage tank. After stopping adding the buffer, the upper cover 11 is closed again to prevent dust on the top from entering the storage tank. After the buffer is stored for a long time, the solid-liquid separation will occur, resulting in the phenomenon of buffer stratification or because the components in the buffer evaporate into the air, causing the buffer concentration to change. These situations can be solved by the mixing mechanism 5. Start the stepper motor 4 at the bottom of the outer cylinder 2, and drive the inner cylinder 7 to rotate through the stepper motor 4. The outer cylinder 2 and the inner cylinder 7 are connected by The roller 12 is connected, and the roller 12 is used to support the inner cylinder 7, so as to prevent the inner cylinder 7 from colliding with the outer cylinder 2 due to eccentricity during rotation. A blade 10 is provided in the wall of the inner cylinder 7, so during the rotation of the inner cylinder 7, the blade 10 is synchronously driven to rotate, and then the buffer in the inner cylinder 7 is driven to rotate synchronously, so as to stir the buffer and solve the stratification. Similarly, during the stirring of the inner cylinder 7, additives can be added to the mixing mechanism 5, and the additives flow into the inner cylinder 7 through the mixing mechanism 5, and are mixed with the buffer under the stirring of the inner cylinder 7. When the storage tank completes the storage work, the inner wall of the inner cylinder 7 can be rinsed by the spray mechanism 6, so as to prevent the buffer from remaining on the inner cylinder 7 and causing contamination to the next batch of buffer.

[0041] When the inner cylinder 7 is driven by the stepper motor 4, the additive is poured into the feed box 51 on the top of the fixed frame 3 during the process of stirring the buffer. The additive entering the feed box 51 enters the square tube 53 through the feed pipe 52. There is an outlet pipe 54 arrayed on the square tube 53, so the additive enters the buffer through the outlet pipe 54. Because the buffer is driven by the inner cylinder 7 and rotates in the inner cylinder 7, the additive can enter the rotating buffer and then fully merge with the buffer. Because the square tube 53 is square, the buffer is blocked by the square tube 53 during the rotation, thereby disrupting the rotation direction of the buffer, so that the buffer can be further stirred.

[0042] After the storage tank has finished storing the buffer, the buffer in the tank can be released to the outside by opening the water outlet pipe 9, and then the water outlet pipe 9 is kept in the open state, and the clean water pipe from the outside is connected to the round pipe on the top of the water discharge box 61, so that the clean water enters the water discharge box 61. After the clean water enters the water discharge box 61, it enters the fixed frame 63 through the water inlet pipe 62, and then is sprayed on the inner cylinder 7 through the fixed frame 63, so that the inner wall of the inner cylinder 7 is cleaned. In the process of cleaning the inner cylinder 7, Start the stepper motor 4 to force the inner cylinder 7 to rotate, further increasing the cleaning of the inner cylinder 7. A baffle cone 64 is fixed in the fixed frame 63. Therefore, the clean water is blocked by the baffle cone 64 and sprayed onto the inner cylinder 7 along the outer wall of the baffle cone 64, thereby increasing the spraying area of ​​the clean water. The baffle cones 64 are fixed by connecting rods 65 to prevent the position of the baffle cones 64 from shifting. The sewage for cleaning the inner cylinder 7 flows into the fixed ring 8, and then flows to the outlet pipe 9 through the fixed ring 8, so that the sewage can flow out to the outside.
