Detailed Implementation

[0029] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0030] See Figure 1-6 A mixing device for recycling waste slurry from a concrete mixing plant includes a cylinder 3. Multiple support legs 2 are fixed to the bottom of the cylinder 3. A top plate 7 is installed at the top of the cylinder 3, and a support structure is fixed to the top of the top plate 7. A top mixing power device for providing mixing power is fixed to the top of the support structure. The output end of the top mixing power device is connected to a first mixing shaft 15, on which an annular mixing paddle structure is installed. A bottom motor 4 is fixed to the bottom of the cylinder 3 via a bottom motor base 5. The second mixing shaft 17 of the bottom motor 4 is connected to a bottom mixing assembly, which is located at the inner bottom of the cylinder 3. This mixing device can be used to achieve thorough homogenization of the recycled slurry during the concrete slurry recycling process, thereby realizing the secondary utilization of waste slurry and ensuring the performance of the prepared concrete, thus achieving the purpose of resource conservation and utilization.

[0031] In this process, the concrete waste slurry to be recycled is placed into the inside of the cylinder 3. Then, the top stirring power device is started, which drives the first stirring shaft 15, which in turn drives the annular stirring paddle structure to stir the slurry. At the same time, the bottom motor 4 is started, which drives the bottom stirring component to stir and agitate the slurry at the bottom of the cylinder 3. This achieves thorough homogenization of the slurry and ensures that its reuse performance remains consistent.

[0032] In this example, to ensure the stability of the entire mixing device, a base plate 1 is fixed to the bottom of the support leg 2. The base plate 1 is fixedly connected to the mounting foundation by anchor bolts. The base plate 1 can be used to reliably fix the support leg 2, thereby ensuring the stability and reliability of the entire cylinder 3.

[0033] Furthermore, to ensure the reliability of the fixed installation of the top stirring power unit, the support structure includes a column 8 fixed to the top of the top plate 7, and a crossbar 9 fixed to the top of the column 8 on the same side. The ends of the crossbars 9 are fixedly connected by a connecting plate 10. This support structure enables reliable installation and fixation of the top stirring power unit, thereby ensuring its subsequent stable power output.

[0034] Furthermore, the top stirring power device includes a stirring motor 14, with a reducer 13 mounted on the output shaft of the stirring motor 14. The reducer 13 is fixed to the top of the motor mounting plate 11 via a reducer base 12, and the motor mounting plate 11 is fixed to the top of the crossbar 9. The output shaft of the reducer 13 is connected to a first stirring shaft 15, which is rotatably supported on a bearing seat 6, which is fixed to the center of the top plate 7. This top stirring power device primarily provides rotational power to the annular stirring paddle structure. During operation, when stirring is required, the stirring motor 14 is started, driving the reducer 13, which in turn drives the first stirring shaft 15. The first stirring shaft 15 then rotates the annular stirring paddle structure, thereby achieving the stirring of the concrete slurry through the annular stirring paddle structure.

[0035] Furthermore, the annular stirring paddle structure includes a first sleeve 21 installed on the upper part of the first stirring shaft 15. Extending rods 19 are fixed to both sides of the first sleeve 21, and a vertical rod 20 is fixed to the bottom end of the extending rods 19. The bottom end of the vertical rod 20 is connected to a second sleeve 27 via a bottom bent rod 26. The second sleeve 27 is fixed to the lower part of the first stirring shaft 15. Multiple three-bladed stirring paddles 22 are mounted on the first stirring shaft 15. Multiple movable stirring plate assemblies are installed on the vertical rod 20. This annular stirring paddle structure enables thorough stirring of the slurry inside the cylinder, thereby achieving thorough mixing of the additives and ensuring the performance of the prepared slurry. During operation, the first stirring shaft 15 drives the extending rods 19, which in turn drives the vertical rod 20, which in turn drives the movable stirring plate assemblies, thus achieving stirring of the slurry.

[0036] Furthermore, the movable stirring plate assembly includes an ear seat 23 fixed to the outer wall of the upright 20, and a stirring plate 25 is hinged to the ear seat 23 via a rotating pin 24. The movable stirring plate assembly described above effectively enhances the stirring effect on the slurry.

[0037] Furthermore, the bottom stirring assembly includes a stirring impeller 28 mounted on the top of the second stirring shaft 17, and a protective cover 29 is provided around the stirring impeller 28. The bottom stirring assembly described above can achieve a certain flow effect on the slurry at the bottom, effectively preventing sedimentation and ensuring a good mixing effect.

[0038] Furthermore, the bottom stirring assembly is eccentrically installed inside the cylinder 3, offset from the center of the cylinder 3 by a certain distance. This eccentric installation structure ensures effective subsequent mixing and thus guarantees the mixing quality of the slurry.

[0039] Furthermore, multiple slurry inlet pipes 16 are provided on the upper outer wall of the cylinder 3, and multiple slurry outlet pipes 18 are provided at the bottom end of the cylinder 3. The slurry inlet pipes 16 facilitate the subsequent inflow of slurry. The slurry inlet pipes 16 can be connected to a waste slurry recovery tank through pipelines, thereby automatically inputting slurry into the cylinder 3. At the same time, the slurry outlet pipes 18 facilitate the recovery of the stirred slurry for reuse.

[0040] The working process and principle of this utility model:

[0041] In the specific working process, firstly, when reusing slurry that needs to be recycled, the slurry is fed into the inside of the cylinder 3, and additives are added again according to performance requirements. Then, the top stirring power device is started. The stirring motor 14 is started, which drives the reducer 13, which in turn drives the first stirring shaft 15. The first stirring shaft 15 drives the extension rod 19, which in turn drives the upright 20, which in turn drives the movable stirring plate assembly, thereby achieving stirring of the slurry. At the same time, the bottom motor 4 is started, which drives the second stirring shaft 17, which in turn drives the stirring impeller 28. The stirring impeller 28 stirs and agitates the slurry at the bottom of the cylinder 3, thereby achieving full homogenization of the slurry and ensuring that its reuse performance remains consistent.
