Description

Technical Field

[0001] This utility model relates to the field of concrete admixture processing technology, specifically a mixing device for producing concrete admixtures. Background Technology

[0002] Concrete admixtures (also known as concrete additives) are chemical substances added to concrete during the mixing process, in addition to cement, aggregates, and water. Their purpose is to improve the performance of concrete, enhancing its workability, durability, strength, and other properties. The use of admixtures can improve the workability, economy, and long-term performance of concrete under different environments and working conditions.

[0003] Existing concrete admixtures require manual mixing during processing to ensure proper integration with concrete components. However, manual mixing is time-consuming, impacting production efficiency. Furthermore, some finer or granular admixtures may not mix completely, resulting in low uniformity and high labor intensity. No solutions have yet been proposed to address these technical problems. Utility Model Content

[0004] To address the problems in related technologies, this utility model proposes a mixing device for concrete admixture production to overcome the aforementioned technical problems in existing related technologies. The purpose of this utility model is to achieve automated and thorough mixing of admixtures and concrete, solving the problems of poor mixing effect and uneven mixing caused by manual operation, saving manual mixing time, improving production efficiency, ensuring stable concrete performance in each batch, avoiding inconsistent results, and preventing local concentrations from being too high or too low, which would affect the performance of the concrete.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for producing concrete admixtures, comprising a mixing chamber, a top cover on the top of the mixing chamber, a drive motor mounted on the top of the top cover, a main gear movably connected to the center of the top of the mixing chamber, the output end of the drive motor fixedly connected to the top of the main gear, side gears meshing on both sides of the main gear, a plurality of teeth arranged in a ring structure on the inner wall of the top cover, a plurality of rotating shafts inside the mixing chamber, a plurality of arc-shaped openings on both sides of the top of the mixing chamber, one end of the top of the rotating shaft passing through the arc-shaped opening and extending to the top of the mixing chamber, and the end connected to the bottom end of the side gear, and a plurality of stirring blocks arranged on the rotating shaft.

[0006] Preferably, a feed pipe is connected to the top side of the mixing box, a number of base frames are fixedly connected to the outer surface of the bottom end of the mixing box, and a discharge pipe is connected to the center of the bottom of the mixing box.

[0007] Preferably, the two sides of the side gear mesh with the main gear and the meshing gear, respectively.

[0008] Preferably, there are two of each of the side gear, rotating shaft, and arc-shaped opening.

[0009] Preferably, the discharge pipe is equipped with a valve.

[0010] Preferably, the bottom of the mixing box is inclined at an angle of 10° to 40°.

[0011] Preferably, the inner wall of the mixing box is provided with a wear-resistant layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention relates to a mixing device for producing concrete admixtures. A drive motor rotates the main gear, which in turn drives the side gears to move in a ring while simultaneously rotating itself. The side gears, in their movement and rotation, drive the rotating shaft to move and rotate, thereby mixing the admixtures and concrete in an automated process. This achieves thorough mixing of the admixtures and concrete, solving the problems of poor mixing and uneven mixing caused by manual operation. It saves manual mixing time, improves production efficiency, ensures stable concrete performance in each batch, avoids inconsistent results, and prevents localized high or low concentrations that could affect concrete performance.

[0019] Example

[0020] Please see Figure 1-3This utility model proposes a technical solution for a mixing device for producing concrete admixtures: a mixing device for producing concrete admixtures includes a mixing box 1, specifically, the mixing box 1 is cylindrical; a top cover 5 is provided on the top of the mixing box 1, specifically, the top cover 5 serves to support a drive motor 6; the drive motor 6 is mounted on the top of the top cover 5, a main gear 7 is movably connected to the center of the top of the mixing box 1, the output end of the drive motor 6 is fixedly connected to the top of the main gear 7, side gears 8 mesh on both sides of the main gear 7, and a plurality of teeth 9 are provided on the inner wall of the top cover 5, the plurality of teeth 9 being arranged in a ring structure, specifically, when the drive motor is started... Machine 6 drives the main gear 7 to rotate. Since the two sides of the side gear 8 mesh with the main gear 7 and the meshing gear 9 respectively, the main gear 7 drives the side gear 8 to move in a ring while rotating on its own axis. The mixing box 1 is equipped with several rotating shafts 10. Several arc-shaped openings 11 are opened on both sides of the top of the mixing box 1. One end of the top of the rotating shaft 10 passes through the arc-shaped opening 11 and extends to the top of the mixing box 1. The end of the shaft is connected to the bottom end of the side gear 8. Several stirring blocks 12 are provided on the rotating shaft 10. Specifically, when the side gear 8 moves and rotates, it drives the rotating shaft 10 to move and rotate, thereby mixing the additives and concrete by the stirring blocks 12.

[0021] Please see Figure 1-2 As shown, further, a feed pipe 2 is connected to the top side of the mixing box 1, several base frames 3 are fixedly connected to the outer surface of the bottom end of the mixing box 1, and a discharge pipe 4 is connected to the center of the bottom of the mixing box 1.

[0022] In this embodiment, the material enters the interior of the mixing box 1 through the feed pipe 2, the base frame 3 supports the mixing box 1, and the discharge pipe 4 discharges the material after the additives and concrete are mixed.

[0023] Please see Figure 2 As shown, furthermore, the two sides of the side gear 8 mesh with the main gear 7 and the meshing gear 9, respectively.

[0024] Please see Figure 2-3 As shown, furthermore, there are two of each of the side gear 8, the rotating shaft 10, and the arc-shaped opening 11.

[0028] In this embodiment, it is beneficial for the discharge of materials.

[0029] Please see Figure 2 As shown, a wear-resistant layer is further provided on the inner wall of the mixing box 1.

[0030] In this embodiment, the wear-resistant layer is an existing one to prevent severe wear inside the mixing tank 1 when the admixture is mixed with concrete, thereby extending the service life of the mixing tank 1.

[0031] The working principle of this utility model:

[0032] The additives and concrete to be mixed are slid into the mixing box 1 through the feed pipe 2. The drive motor 6 is started to drive the main gear 7 to rotate. Since the two sides of the side gear 8 are respectively engaged with the main gear 7 and the meshing gear 9, the main gear 7 drives the side gear 8 to move in a ring while rotating on its own axis. The side gear 8 drives the rotating shaft 10 to move and rotate while moving and rotating, so that the mixing block 12 mixes the additives and concrete. After the mixing is completed, the valve is opened and the mixture is discharged through the discharge pipe 4.

[0033] This invention enables automated mixing of admixtures and concrete, solving the problems of poor mixing and uneven mixing caused by manual operation. It saves manual mixing time, improves production efficiency, ensures stable concrete performance in each batch, avoids inconsistent results, and prevents local concentrations from being too high or too low, which would affect the performance of the concrete.
