[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] To address the high energy consumption issue inherent in traditional granulation methods that utilize a "mixer + granulator," this solution provides Example 1: Please see Figures 1-5In this utility model: a vertical shaft mixing and granulation integrated machine for fly ash stabilization treatment includes a cylinder 1. The top of the cylinder 1 is connected to a feed pipe 2 and a liquid addition pipe 3. A rotating shaft 4 is rotatably connected to the inner wall of the cylinder 1. A motor 12 is fixedly connected to the top of the cylinder 1. The output shaft of the motor 12 is fixedly connected to the rotating shaft 4. An annularly distributed upper dispersion paddle 5 is fixedly connected to the middle of the rotating shaft 4. An annularly distributed lower granulation paddle 6 is fixedly connected to the bottom of the rotating shaft 4. A hydraulic feeding mechanism 7 is provided at the bottom of the cylinder 1. The hydraulic feeding mechanism 7 includes a discharge hole 701, which is opened on the cylinder 1. A sealing block 702 is slidably connected to the inner wall of the discharge hole 701. A hydraulic push rod 703 is fixedly connected to the outer side of the cylinder 1. A moving plate 704 is fixedly connected to the telescopic end of the hydraulic push rod 703. A connecting rod 705 is fixedly connected to the left side of the moving plate 704. The left end of the connecting rod 705 is fixedly connected to the sealing block 702.

[0016] In this invention, fly ash first enters the cylinder 1 through the feed pipe 2, and stabilizing agent and water are quantitatively injected through the liquid addition pipe 3. Motor 12 drives the rotating shaft 4, which drives the upper dispersing paddle 5 to rotate at high speed, fully shearing and mixing the fly ash and liquid. After mixing, the material falls to the lower granulation paddle 6. The squeezing and tumbling action of the paddle blades causes the wet material to form dense particles. After granulation is completed, the hydraulic push rod 703 drives the moving plate 704 to move to the left. The moving plate 704 drives the sealing block 702 to slide out from the discharge hole 701. At this time, the cylinder 1 loses its seal, and the particles will be discharged from the discharge hole 701 to complete the unloading. Mixing, granulation, and unloading are all completed in a single unit, achieving efficient and stable processing. This is more energy-efficient and reduces material transfer losses compared to the traditional step-by-step "mixer + granulator" model.

[0017] Please see Figure 4 The inner wall of the cylinder 1 is fixedly connected with a wear-resistant layer 8, which is a wear-resistant ceramic lining layer.

[0018] In this invention, by providing a wear-resistant layer 8 composed of wear-resistant ceramic lining plates on the inner wall of the cylinder 1, the wear resistance of the cylinder 1 can be improved, and the service life of the device can be extended.

[0019] Please see Figures 1-4 The cylinder 1 is fixedly connected to a hopper 9 on its right side, and the bottom of the hopper 9 is connected to a discharge pipe 10.

[0020] In this invention, the hopper 9 can be used to receive the particles discharged from the discharge hole 701. After the particles enter the hopper 9, they will be discharged from the discharge pipe 10, which makes it convenient for workers to collect them.

[0021] To address the issue that traditional unloading mechanisms lack the function of particle screening, this solution provides Embodiment Two: Please see Figure 4and 5 The hopper 9 is equipped with a sieve cylinder 11 that is rotatably connected to it, and the left end of the sieve cylinder 11 is rotatably connected to the inner wall of the discharge hole 701.

[0022] In this invention, during unloading, the sealing block 702 slides into the screen cylinder 11 from the discharge hole 701. At this time, the particles discharged from the discharge hole 701 fall into the screen cylinder 11. The screen cylinder 11 is provided with screen holes that allow particles of the required diameter to pass through. Qualified particles will be discharged smoothly from the screen cylinder 11, while unqualified particles with larger diameters or clumps will remain in the screen cylinder 11, thereby achieving the effect of particle screening.

[0023] After the qualified particles are discharged, the hydraulic push rod 703 then drives the sealing block 702 to move to the left until the sealing block 702 is pulled out of the screen cylinder 11. At this time, the unqualified particles inside the screen cylinder 11 will be discharged from the screen cylinder 11, thus completing the unloading of unqualified particles.

[0024] When using the sieve cylinder 11 to screen particles, a problem of low screening efficiency occurs. To solve this problem, this solution provides Example 3: Please see Figure 4 and 5 The cylinder 1 is equipped with a second motor 13, and the output shaft of the second motor 13 is fixedly connected to a drive gear 14. The left side of the screen cylinder 11 is fitted with a passive gear ring 15 fixedly connected to it. The drive gear 14 and the outer side of the passive gear ring 15 are rotatably connected to the cylinder 1, and the drive gear 14 and the passive gear ring 15 mesh with each other.

[0025] In this invention, when screening particles, motor 2 13 is turned on, which drives the drive gear 14 to rotate. The drive gear 14 meshes with the passive gear ring 15, which in turn drives the screen cylinder 11 to rotate. During the rotation of the screen cylinder 11, the screening of particles is accelerated, and the unloading efficiency of the device is improved.

[0026] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
