[0002] With the rapid development of the construction industry and the increasing awareness of environmental protection, recycled concrete, as an important material for resource recycling, is being used more and more widely. The cleaning quality of recycled concrete aggregates directly affects the overall performance of recycled concrete and the application effect of subsequent projects.
[0003] However, traditional cleaning devices usually rely on simple rotation or rinsing methods, which are insufficient to achieve thorough mixing and efficient cleaning of concrete aggregates. As a result, impurities attached to the surface of the aggregates cannot be completely removed, and the cleaning effect is not ideal. This not only reduces the quality of recycled aggregates but also has an adverse effect on the subsequent concrete preparation process, thereby weakening the overall performance of recycled concrete. Utility Model Content

By combining a mesh cleaning cylinder with a mixing roller, along with the brushing function of a brush and the spraying of a spray pipe, efficient cleaning of concrete aggregates is achieved. The use of a gear and gear ring meshing transmission structure allows the mixing roller to rotate simultaneously with the mesh cleaning cylinder, further enhancing the uniformity of mixing and brushing, significantly improving the cleaning effect.

Detailed Implementation
[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0017] This utility model discloses a recycled concrete aggregate cleaning device, which mainly includes a frame 1, a mesh cleaning cylinder 2, a mixing roller 3, a spray pipe 4, a motor 5, a mixing plate 6, a gear ring 7, a brush 8, an annular support frame 9, a connecting shaft 10, a guide groove 13, and a gear 15; Figure 1 As shown, the entire device is supported by a frame 1, which is welded from high-strength steel and has good stability and load-bearing capacity. The mesh cleaning cylinder 2 is a hollow cylindrical structure with open ends. Annular support frames 9 are set at both ends inside the cylinder. A connecting shaft 10 is fixedly installed in the middle of the annular support frame 9. The connecting shaft 10 is connected to the frame 1 through bearings, so that the mesh cleaning cylinder 2 is installed at an angle on the frame 1. This ensures that the aggregate can gradually move towards the discharge port along the inside of the mesh cleaning cylinder 2 during the cleaning process, and also facilitates the discharge of the aggregate after cleaning. Multiple annular reinforcing ribs 12 are welded equidistantly along the axial direction on the outer wall of the mesh cleaning cylinder 2 to enhance the overall strength and deformation resistance of the mesh cleaning cylinder 2.
[0018] The mixing rollers 3 are evenly distributed among the annular support frames 9. The ends of the mixing rollers 3 are rotatably connected to the annular support frames 9 via bearings, allowing the mixing rollers 3 to rotate freely on the annular support frames 9. Multiple sets of annularly distributed mixing plates 6 are equidistantly arranged along the axial direction on the mixing rollers 3. Brushes 8 are evenly arranged between each set of mixing plates 6. The gap between the mixing plates 6 and the inner wall of the mesh cleaning cylinder 2 is 2-5mm. The surface of the mixing plates 6 is provided with anti-slip texture to enhance the friction during the mixing process. The brushes 8 are designed to scrub the surface of the aggregate, further improving the cleaning effect. A gear 15 is provided at the end of the mixing rollers 3. The gear 15 meshes with a gear ring 7 fixed on the inner wall of the mesh cleaning cylinder 2. The gear ring 7 is fixed to the inner wall of the mesh cleaning cylinder 2 by bolts. When the mesh cleaning cylinder 2 rotates, the gear ring 7 drives the gear 15 to rotate, so that the mixing rollers 3 rotate on their own axis while revolving with the mesh cleaning cylinder 2, realizing the dual functions of mixing and scrubbing.
[0019] The spray pipe 4 is fixedly installed on the inner wall of the guide channel 13 by clamps, located on both sides of the mesh cleaning cylinder 2. One end of the spray pipe 4 is connected to an external water supply pipe, and the other end is closed. A water pump is installed on the water supply pipe. Multiple nozzles are equidistantly arranged on the spray pipe 4 along the axial direction, and the nozzles are arranged radially along the mesh cleaning cylinder 2. The spray center line is perpendicular to the axis of the mesh cleaning cylinder 2. The cleaning water is sprayed into the mesh cleaning cylinder 2 through the nozzles, thereby achieving transverse penetration cleaning of the aggregate.
[0020] The motor 5 is fixedly mounted on one side of the frame 1 by bolts. Its output shaft is connected to the connecting shaft 10 through a coupling, thereby driving the mesh cleaning cylinder 2 to rotate. When the motor 5 starts, its output shaft drives the connecting shaft 10 to rotate through the coupling, thereby causing the mesh cleaning cylinder 2 to rotate around the axis of the connecting shaft 10. The rotation speed of the mesh cleaning cylinder 2 can be adjusted according to the actual cleaning needs to adapt to the cleaning of aggregates with different particle sizes and contamination levels.
[0021] The frame 1 is inclinedly installed with a V-shaped cross-section guide channel 13. The guide channel 13 is located at the bottom of the mesh cleaning cylinder 2, and a discharge port 14 is opened at the bottom end of the guide channel 13. The semi-enclosed structure of the guide channel 13 forms a physical barrier, which effectively blocks splashing water droplets generated by water flow impact or aggregate collision during the cleaning process, and at the same time facilitates the guidance of sewage and mud to be discharged and collected along the discharge port 14.
[0022] A feed hopper 17 is installed on the frame 1 near the feed inlet of the mesh washing cylinder 2 to guide the aggregate into the washing cylinder evenly and prevent the material from scattering. A collection trough 16 is installed at an angle on the frame 1 near the discharge outlet of the mesh washing cylinder 2. The collection trough 16 is located at the bottom of the mesh washing cylinder 2 and a vibration motor 11 is installed at its bottom. The clean aggregate after washing is collected by gravity and, in conjunction with the vibration motor 11, can prevent the aggregate from remaining and accumulating in the collection trough 16, ensuring continuous discharge.
[0023] In summary, this invention achieves efficient cleaning of recycled concrete aggregates by using the mesh cleaning cylinder 2 and the mixing roller 3 in conjunction with the brushing function of the brush 8 and the spraying function of the spray pipe 4. The meshing transmission structure of the gear 15 and the gear ring 7 allows the mixing roller 3 to rotate on its own axis while revolving with the mesh cleaning cylinder 2, further improving the uniformity of mixing and brushing and significantly enhancing the cleaning effect. It effectively solves the problems of poor cleaning effect and low efficiency caused by insufficient mixing in traditional cleaning devices, improving the cleanliness and quality of aggregates and providing a strong guarantee for improving the overall performance of recycled concrete.
[0024] Work process:
[0025] First, the recycled concrete aggregate to be cleaned is fed into the mesh washing cylinder 2 through the feed hopper 17. After starting the motor 5, the motor 5 drives the connecting shaft 10 to rotate through the coupling, and drives the mesh washing cylinder 2 to rotate through the annular support frame 9. Since the mesh washing cylinder 2 is in an inclined state, the aggregate gradually moves towards the discharge port along the inside of the mesh washing cylinder 2 under the combined action of gravity and the rotation of the mesh washing cylinder 2. At the same time, the mixing roller 3 revolves with the mesh washing cylinder 2, and the aggregate is cleaned by the meshing action of the gear 15 and the gear ring 7. The aggregate is now rotating. The mixing plate 6 and brush 8 on the mixing roller 3 fully mix and wash the aggregate during rotation, removing impurities attached to the surface of the aggregate. The water pump on the water supply pipe is turned on, and the water pump draws the cleaning water into the spray pipe 4 and sprays the cleaning water into the mesh cleaning cylinder 2 through the nozzle. The cleaning water washes down the impurities during the mixing and washing process and is discharged through the mesh of the mesh cleaning cylinder 2 to the guide channel 13. The cleaned aggregate is discharged from the outlet of the mesh cleaning cylinder 2, thus completing the entire cleaning process.
[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
