The device includes a hollow tank supported by multiple support rods. The tank has an inlet at the top and an outlet at the bottom. A discharge pipe with a control valve is connected to the outlet. However, this solution relies solely on a single spherical nozzle for cleaning, resulting in poor cleaning effectiveness and difficulty in thoroughly removing residues from the tank. Furthermore, the spherical nozzle, located inside the tank, is prone to clogging, affecting normal operation. Additionally, the nozzle is difficult to disassemble and maintain. Therefore, a pre-mixed concrete admixture homogenization device is provided to address these issues. Utility Model Content

The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figures 1 to 5In this embodiment of the present invention, a premixed concrete admixture homogenization device includes: a support base 1, an upper fixing block 2 fixedly connected above the support base 1, a mixing tank 3 fixedly connected to the side of the upper fixing block 2, the interior of the upper fixing block 2 communicating with the interior of the mixing tank 3, a discharge pipe 4 provided below the mixing tank 3, an electromagnetic pneumatic valve 5 fixedly connected to the outside of the discharge pipe 4, a movable mounting plate 6 provided on the side of the mixing tank 3 away from the upper fixing block 2, a feeding hopper 7 fixedly connected above the upper fixing block 2, the bottom of the feeding hopper 7 penetrating into the interior of the upper fixing block 2, a first drive motor 8, a cleaning water tank 9 and a drive water pump 10 fixedly connected above the support base 1, a first gear 11 fixedly connected to the rotating shaft of the first drive motor 8, a hollow rotating shaft 12 provided inside the upper fixing block 2, the interior of the cleaning water tank 9 connected to the water inlet of the drive water pump 10 via a hose, and the water outlet of the drive water pump 10 rotatably connected to one end of the hollow rotating shaft 12 via a rotary joint. A second gear 13 is fixedly connected to the side of the rotating shaft 12. The first gear 11 and the second gear 13 are compatible. Three sets of stirring blades 14 are fixedly connected to the side of the hollow rotating shaft 12. A fixed bracket 15 is fixedly connected to the side of the hollow rotating shaft 12. A cleaning scraper 16 is fixedly connected to the outside of the fixed bracket 15. A water storage tank 17 is opened on the inner side of the movable mounting plate 6. A bearing 18 is fixedly connected to the inner side of the water storage tank 17. A sealing ring 19 is fixedly connected to the inner side of the bearing 18. The movable mounting plate 6 and the stirring tank 3 have compatible threads on their sides. When the movable mounting plate 6 and the stirring tank 3 are tightly connected by threads, one end of the hollow rotating shaft 12 abuts against the sealing ring 19. Cleaning water can flow from the cleaning water tank 9 through the drive water pump 10 and the hollow rotating shaft 12 into the water storage tank 17. The size of the sealing ring 19 on the inner side of the bearing 18 is compatible with the hollow rotating shaft 12. Multiple sets of nozzles 20 are fixedly connected to the inner side of the movable mounting plate 6. The nozzles 20 are connected to the inside of the water storage tank 17.

[0025] Using the above scheme: the admixture in the mixing tank 3 is driven by the first gear 11 driven by the first drive motor 8 to mesh with the second gear 13 on the hollow rotating shaft 12, thereby driving the stirring fan blades 14 to uniformly stir the admixture.

[0026] Reference Figure 1 and Figure 2 An electric telescopic rod 21 is fixedly connected above the support base 1. A rotating fixing block 22 is fixedly connected to the movable end of the electric telescopic rod 21. Feeding hoppers 24 are rotatably connected to both sides of the rotating fixing block 22. A second drive motor 23 is fixedly connected to the side of the feeding hopper 24. The rotating shaft of the second drive motor 23 passes through the feeding hopper 24 and is fixedly connected to the rotating fixing block 22.

[0027] Using the above method: when it is necessary to feed the premixed concrete admixture into the feed hopper 7, simply retract the electric telescopic rod 21 to the maximum extent, pour the premixed concrete admixture into the feed hopper 24, and then drive the electric telescopic rod 21 to the appropriate position, drive the second drive motor 23 to drive the feed hopper 24 to rotate relative to the position of the rotating fixed block 22, and pour the admixture into the feed hopper 7.

[0028] The working principle of this utility model is as follows: First, the electric telescopic rod 21 is retracted to its maximum extent to make room for the feeding hopper 24. The premixed concrete admixture is poured into the feeding hopper 24. Then, the electric telescopic rod 21 drives the rotating fixed block 22 and the feeding hopper 24 to move to a suitable position so that the feeding hopper 24 is close to the inlet hopper 7. The second drive motor 23 is started, and its rotating shaft drives the feeding hopper 24 to rotate relative to the rotating fixed block 22 until the outlet of the feeding hopper 24 is aligned with the inlet of the inlet hopper 7. The admixture automatically falls into the mixing tank 3 under the action of gravity.

[0029] When the admixture enters the mixing tank 3, the first drive motor 8 is started. The rotating shaft of the first drive motor 8 drives the first gear 11 to rotate. Since the first gear 11 is matched and meshed with the second gear 13 on the hollow rotating shaft 12, the hollow rotating shaft 12 will rotate accordingly. The three sets of stirring blades 14 installed on the side of the hollow rotating shaft 12 rotate with the shaft to uniformly stir the admixture in the mixing tank 3. At the same time, the cleaning scraper 16 on the outside of the fixed bracket 15 rotates with the hollow rotating shaft 12 to scrape off and prevent residues on the inner wall of the mixing tank 3.

[0030] After mixing is complete, the discharge pipe 4 can be opened or closed by controlling the switch of the electromagnetic pneumatic valve 5, thereby controlling the discharge of the admixture in the mixing tank 3.

[0031] When cleaning the inside of the mixing tank 3 is required, the drive water pump 10 is started, and the cleaning water is pumped to one end of the hollow rotating shaft 12. The shaft is rotated through a rotary joint. When the movable mounting plate 6 is tightly connected to the mixing tank 3 by threads, one end of the hollow rotating shaft 12 abuts against the sealing ring 19, and the cleaning water flows from the hollow rotating shaft 12 into the water storage tank 17. The cleaning water in the water storage tank 17 is then sprayed out through multiple sets of nozzles 20, directly spraying onto the inner wall of the mixing tank 3 to clean the inner wall. At the same time, the first drive motor 8 can be started to drive the cleaning scraper 16 to rotate, further enhancing the cleaning effect and better removing residues on the inner wall of the mixing tank 3. Since the nozzles 20 are set on the detachable movable mounting plate 6, cleaning and maintenance are more convenient and less prone to clogging.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
