[0029] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination should be considered non-existent and not within the scope of protection claimed by this utility model.
[0030] This utility model provides a technical solution; please refer to [link / reference]. Figure 1-4 The system includes: a mixing chamber 1, a premixing and grinding assembly 2 installed inside the mixing chamber 1, a drive motor 6 mounted on the top of the mixing chamber 1, a support frame 11 with one end fixedly connected to the inner wall of the mixing chamber 1 and the other end fixedly connected to the premixing and grinding assembly 2, a mixing plate 12 installed at the bottom of the support frame 11, and a guide plate 14 fixedly connected to the inner wall of the mixing chamber 1.

[0031] Furthermore, one end of the drive spindle 8 is fixedly connected to the output shaft of the drive motor 6, and the other end of the drive spindle 8 movably passes through the support frame 11 and is fixedly connected to the top center of the mixing tray 12. Two sets of rotating shafts 4 are symmetrically arranged on both sides of the drive spindle 8 and rotatably connected to the top of the inner wall of the mixing chamber 1. Through the fixed connection between the drive spindle 8 and the output shaft of the drive motor 6, and the arrangement of the rotating shafts 4, power can be effectively transmitted to the mixing tray 12. The two sets of symmetrically arranged rotating shafts 4 ensure the uniform rotation of the mixing tray, improving the uniformity and effect of mixing.
[0032] Furthermore, identical pulleys 7 are fixedly fitted onto the outer walls of the drive shaft 8 and the two sets of rotating shafts 4, and the pulleys 7 are connected by a belt 5. The pulleys 7 on the outer walls of the drive shaft 8 and the rotating shafts 4 are connected by the belt 5, which can effectively distribute power to each component, ensure the coordinated operation of each part, and thus improve the overall stirring efficiency.
[0033] Furthermore, the rotating shaft 4 extends movably to the outer wall below the support frame 11 and is provided with a ring of annular flow-dividing blades 28. The annular flow-dividing blades 28 are connected to the rotating shaft 4 through several sets of fixed columns 29. The arrangement of the annular flow-dividing blades 28 helps guide the flow direction of the material and enhances the mixing effect. At the same time, the fixed columns 29 ensure the stability of the annular flow-dividing blades, thereby reducing dead zones of material and improving the overall mixing.

[0035] Furthermore, the guide plate 14 is inclined and located below the support frame 11, and a material through hole 16 is opened on the guide plate 14. Several sets of cutting blades 15 are installed at the bottom of the guide plate 14. The inclined setting of the guide plate 14 and the design of the material through hole 16 can optimize the material flow path, and the cutting blades 15 help to improve the mixing efficiency of the material, thereby improving the quality of the slurry.
[0036] Furthermore, the second drive motor 17 is mounted on the outer wall of the mixing tank 1 and extends movably into the mixing tank 1. One end of the second rotating shaft 18 is rotatably connected to the inner wall of the mixing tank 1, and the other end of the rotating shaft 18 is fixedly connected to the output end of the second drive motor 17. The second rotating shaft 18 is located below the guide plate 14, and several sets of stirring blades 19 are fixedly sleeved on the outer wall of the second rotating shaft 18. The connection between the second drive motor 17 and the inner wall of the mixing tank 1 via the second rotating shaft 18 can provide additional stirring action during the stirring process, enhancing the stirring effect. The setting of the stirring blades 19 further improves the mixing effect of the materials.
[0037] Furthermore, the filter screen 20 is fixedly connected to the inner wall of the mixing tank 1, and the filter screen 20 is located below the rotating shaft 18. The fixed connection of the filter screen 20 to the inner wall of the mixing tank 1 and its location below the rotating shaft 18 helps to remove impurities generated during the mixing process, improving the purity and quality of the slurry.
[0038] Furthermore, the bottom of the mixing tank 1 has a trapezoidal structure, and a discharge port 21 is installed at the bottom of the mixing tank 1. A solenoid valve 22 is installed on the discharge port 21. The trapezoidal structure of the bottom of the mixing tank 1 helps to concentrate and discharge materials. The setting of the discharge port 21 and the solenoid valve 22 provides better control and management of material discharge, improving the convenience of operation.
[0039] Furthermore, the premixing and grinding assembly 2 includes: a premixing chamber 23, which is fixedly connected to the inner wall of the mixing chamber 1. The premixing chamber 23 has an elliptical cavity inside, and the inner wall of the premixing chamber 23 is provided with a ring of grinding teeth 24. A drive motor 26 is installed on the outer wall of the rear end of the mixing chamber 1, and the output shaft of the drive motor 26 extends movably into the premixing chamber 23 and is fixedly sleeved with several sets of grinding rods 25. The feed inlet 3 is located on the outer wall of the mixing chamber 1 and communicates with the premixing chamber 23. Two sets of crushing wheels 27 are installed at the outlet at the bottom of the premixing chamber 23, and both sets of crushing wheels 27 are rotatably connected to the inner wall of the mixing chamber 1.
[0040] Preferably, the top of the mixing tank 1 is provided with a liquid inlet.
[0041] Preferably, the models of drive motor 16, drive motor 27 and drive motor 326 can be: YE2 and YE3 series high-efficiency energy-saving motors, YVF series variable frequency speed control motors and YCT series electromagnetic speed control motors.
[0042] Preferably, the solenoid valve 22 can be a 2W series solenoid valve, an EX series explosion-proof solenoid valve, or a ZHCB series high-temperature solenoid valve.
[0043] Working principle and its beneficial effects: When the raw material is put into the premixing and grinding component 2 through the feed port 3, the drive motor 26 is started to drive the grinding rod 25 to rotate in the premixing box 23. This allows the material to be pre-treated and ground before mixing. The pre-treated raw material falls onto the guide plate 14 through two sets of crushing wheels 27, which further enhances the crushing treatment of the material and ensures the fineness and uniformity of the material. Subsequently, liquid is injected into the mixing tank 1 through the liquid inlet at the top of the mixing tank 1, while the drive motor 6 is started to drive the drive shaft 8 to rotate, which in turn drives the mixing plate 12 to rotate, thereby mixing the liquid with the material. At the same time, the drive shaft 8 drives two sets of rotating shafts 4 to rotate through the belt 5. The annular flow divider blades 28 on the two sets of rotating shafts 4 help guide the flow direction of the material, improving the uniformity and effect of the mixing. The mixed material flows out through the material passage hole 16 under the guidance of the guide plate 14. Then, the drive motor 17 is started to drive the rotating shaft 18 to rotate, while several sets of stirring blades 19 can further mix it more thoroughly. When passing through the cutting blade 15, it helps to further crush large particles of material, thereby improving the purity and quality of the slurry. Finally, the material accumulates at the bottom of the mixing tank 1 through the filter screen 20, and the solenoid valve 22 provides better control and management of the discharge function, improving the convenience of operation.
