A motor bracket is fixedly installed on the top of the fermentation tank, and a motor is fixedly installed inside the motor bracket. A rotating shaft is fixedly installed at the output end of the motor, and a rotating drum is fixedly installed at the bottom of the rotating shaft. By installing a water pipe on one side of a measuring instrument, with one end of the water pipe extending into the fermentation tank, the measuring instrument can more accurately measure the concentration of the water-reducing agent inside the fermentation tank.

[0004] When existing high-dosage mother liquor is mixed with low-concentration solvent, it is easy to cause stratification and agglomeration, resulting in uneven dispersion of water-reducing agent. In addition, most existing stirring devices are single stirring modes, which make it difficult to balance dispersion efficiency and mixing effect, and have high energy consumption, thus reducing the effect of use.

9. The use of a high-dosage low-concentration concrete water-reducing agent preparation device, characterized in that, The high-amount low-concentration concrete water reducing agent dispensing device of claim 8 is used, including the following steps: S1, by storing solvent in the interior of the solvent storage tank (201), storing water reducing agent mother liquor in the interior of the water reducing agent mother liquor storage tank (202), and storing additives in the interior of the additive storage tank (203), the top of the tank body is provided with a flip cover (205) and is rotatably connected with a rotating connection seat (204), which is convenient for opening to add corresponding liquid agent to the interior, and the feeding pipeline (206) is connected to the top of the dispensing tank top cover (102) and cooperates with the quantitative valve (207) to quantitatively add different liquid agents to the interior of the dispensing tank body (101) for mixing and dispensing operation; S2, when the liquid agent enters the interior of the dispensing tank body (101), the stirring motor (103) drives the stirring shaft (104) to rotate, and then drives the installation ring (105) and part of the main stirring paddle (106) to rotate, so that the stirring blades (107) distributed on the main stirring paddle (106) mix and stir the liquid agent; S3. Meanwhile, the transmission gears (108) distributed on the stirring shaft (104) provide transmission. The gear ring (110) is installed on the inner wall of the mixing tank (101) through the internal support frame (109) and is distributed in multiple groups. The gear ring (110) and the transmission gear (108) mesh to achieve synchronous rotation. Auxiliary stirring paddles (112) are connected to the gear ring (110) above and below through the rotating shaft (111), realizing the function of synchronous auxiliary rotation stirring and providing further thorough mixing operation. At the same time, the first-stage angled stirring paddle (113) and the second-stage angled stirring paddle (114) are distributed at the bottom of the stirring shaft (104) near the bottom of the inner side of the mixing tank (101), which can further thoroughly stir the bottom of the tank and improve the mixing effect. S4. After the preparation is completed, the water-reducing agent is connected to the conveying pump (301) through the discharge pipe (115) to facilitate the discharge of the water-reducing agent and further conveyed to the conveying pipe (303). The water-reducing agent is then conveyed to the inside of the finished product storage tank (304) through the conveying pipe (303) for storage. The top cover (307) of the finished product tank provides a sealing function at the top. The top cover (307) of the finished product tank is equipped with an inspection cover plate (305) to facilitate the inspection of the inside of the tank from the top. The discharge pipe (306) is located at the bottom of the finished product storage tank (304) to facilitate the discharge of the finished product for use. S5. After the device is used up and the internal parts are emptied, clean water is transported by connecting the water inlet pipe on the side of the booster pump (401) to an external water source, connecting the booster pump (401) to the pipe connector (402), and connecting the first water supply pipe (403) and the second water supply pipe (406) to the pipe connector (402). S6. One end of the first water supply pipe (403) is connected to a first spray ring (404) and a first pressurizing nozzle (405) is distributed at its bottom to facilitate high-pressure rinsing of the interior and components of the mixing tank (101) and reduce residue. One end of the second water supply pipe (406) is connected to a second spray ring (407) and a second pressurizing nozzle (408) is distributed to facilitate high-pressure rinsing of the interior of the finished product storage tank (304), thereby facilitating comprehensive rinsing and cleaning. S7. After cleaning, open both the branch valve (116) and the discharge pipe (306) to facilitate the discharge of the cleaned wastewater.
