The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Example 1:

[0021] Please see Figure 1 As shown, this utility model provides a slurry mixing device for self-compacting concrete preparation, including a support frame 1, a positioning frame 2 welded inside the support frame 1, an arc-shaped clamping plate 10 welded inside the positioning frame 2, a mixing tank 3 fixedly installed inside the arc-shaped clamping plate 10, a drive motor 4 fixedly installed on the top of the support frame 1, a rotating shaft 5 fixedly installed inside the support frame 1 through the output shaft of the drive motor 4, a mixing rod 6 annularly installed on the lower end surface of the rotating shaft 5, a first sealing plate 11 and a second sealing plate 12 for cooperation are respectively installed on the front and rear sides above the mixing tank 3, a push-pull plate 13 is slidably installed on the left end of the first sealing plate 11 and the second sealing plate 12, a positioning clamping bracket 14 is installed on the front and rear sides of the upper end of the support frame 1 by bolts, an adjusting screw 15 is installed on the internal thread of the outer end of the positioning clamping bracket 14, a clamping plate 16 is rotatably installed on the inner end of the adjusting screw 15, the two clamping plates 16 are distributed outside the first sealing plate 11 and the second sealing plate 12, and a discharge pipe 9 is connected to the bottom of the mixing tank 3.

[0022] This technical solution, by setting a first sealing plate 11 and a second sealing plate 12, can seal the top of the mixing tank 3 to prevent mud splashing during the mixing process. At the same time, by adjusting the screw 15 and the clamping plate 16, the first sealing plate 11 and the second sealing plate 12 can be fixed, ensuring the reliability of the seal. The first sealing plate 11 and the second sealing plate 12 can be slidably opened and closed by the push-pull plate 13 and the guide rod, which makes it easy for operators to open the sealing plates to clean and maintain the inside of the mixing tank 3. The operation is simple and convenient.

[0023] Example 2:

[0024] Based on Embodiment 1, this utility model is as follows: Figure 1As shown, a feed pipe 7 is provided through the top right side of the support frame 1. The outlet of the feed pipe 7 corresponds to the top of the mixing tank 3. A control valve 8 is movably installed on the surface of the right end of the feed pipe 7.

[0025] Adopting such Figure 1 The technical solution shown has the discharge port of the feed pipe 7 corresponding to the top of the mixing tank 3. This design ensures that all kinds of raw materials fall accurately into the mixing tank 3 during the addition process, avoiding waste caused by spillage. At the same time, it ensures the accuracy of the raw material ratio, laying the foundation for the uniformity of subsequent mud mixing. The setting of the control valve 8 gives the operator the ability to flexibly control the feeding process. By adjusting the control valve 8, the amount of raw materials added can be precisely controlled according to the mixing requirements, preventing too much or too little raw material from affecting the quality of the mud.

[0026] Secondly, in the technical solution, limiting horizontal plates 17 are fixedly installed on both the front and rear sides of the upper end of the inner cavity of the support frame 1. The tops of the two limiting horizontal plates 17 are respectively attached to the bottoms of the first sealing plate 11 and the second sealing plate 12. A guide rod is longitudinally installed on the right side of the push-pull plate 13. The left ends of the first sealing plate 11 and the second sealing plate 12 are both engaged with the surface of the guide rod through the slot and slidably installed longitudinally.

[0027] Its adoption is as follows Figure 1 The technical solution shown has the top of the limiting horizontal plate 17 in contact with the bottom of the first sealing plate 11 and the second sealing plate 12. This design provides a stable support for the sealing plates. During the mixing process, the equipment will generate a certain amount of vibration. The limiting horizontal plate 17 can effectively limit the vertical displacement of the first sealing plate 11 and the second sealing plate 12, ensuring that they remain in a stable position under vibration, avoiding the sealing effect caused by the shaking of the sealing plates, ensuring the sealing performance of the mixing tank 3, and reducing the possibility of mud splashing.

[0028] The guide rod on the right side of the push-pull plate 13 engages with the slots on the left end of the first sealing plate 11 and the second sealing plate 12, enabling the longitudinal sliding installation of the sealing plates. The guide rod provides precise guidance for the sliding of the sealing plates, allowing the first sealing plate 11 and the second sealing plate 12 to move smoothly along a fixed trajectory during the opening and closing process, avoiding deviation, jamming, or other issues.

[0029] Example 3:

[0030] This utility model is as follows Figures 1-3 As shown, an arc-shaped groove is provided at the center of the first sealing plate 11 and the second sealing plate 12, and the internal shape of the arc-shaped groove matches the external shape of the rotating shaft 5; a support plate is welded to the bottom of the inner cavity of the support frame 1, and a through groove is provided in the middle of the support plate, and the bottom of the mixing tank 3 is connected to the upper edge of the through groove.

[0031] By adopting the above technical solution, the arc-shaped grooves opened at the relative positions of the center of the first sealing plate 11 and the second sealing plate 12, because their internal shape matches the external shape of the rotating shaft 5, can form a tight fit with the rotating shaft 5 when the sealing plates are closed. This design effectively fills the gap between the sealing plates and the rotating shaft 5, greatly improves the sealing integrity of the top of the mixing tank 3, prevents mud from overflowing from the gap between the two during the mixing process, further reduces raw material waste and environmental pollution, and ensures the stability of the mixing operation.

[0032] The working principle of this utility model is as follows: the operator pushes the push-pull plate 13 and uses the guiding action of the guide rod to slide the first sealing plate 11 and the second sealing plate 12 to the closed state, so that the arc groove at the center of the two is tightly fitted with the rotating shaft 5. Then, the adjusting screw 15 at the outer end of the positioning bracket 14 is rotated to cause the pressing plate 16 to move inward and press against the outside of the first sealing plate 11 and the second sealing plate 12. The pressing force is used to fix them, thereby achieving the sealing of the top of the mixing tank 3 and preventing mud splashing during the mixing process.

[0033] The operator opens the control valve 8 at the right end of the feed pipe 7, and feeds the various raw materials required for preparing self-compacting concrete into the mixing tank 3 through the feed pipe 7. During the mixing operation, the drive motor 4 is started, and the output shaft of the drive motor 4 drives the rotating shaft 5 to rotate, which in turn causes the stirring rod 6 on the lower surface of the rotating shaft 5 to rotate. During the rotation, the stirring rod 6 fully stirs the raw materials in the mixing tank 3, making them evenly mixed and forming a slurry that meets the requirements. When the slurry is mixed, the discharge pipe 9 connected to the bottom of the mixing tank 3 is opened, and the mixed slurry is discharged through the discharge pipe 9.
