[0002] Waste mud recycling and granulation equipment is an environmentally friendly treatment device mainly used to dewater, dry, and granulate waste mud generated during drilling, construction, or industrial wastewater treatment, converting it into solid particles. Its core function is to achieve the resource reuse of mud by separating harmful substances, recovering useful components, reducing waste emissions, and using the generated particles for roadbed filling, building material raw materials, or land reclamation, thus reducing environmental pollution risks and saving disposal costs. This equipment combines economic and ecological benefits and is one of the key technologies for green production and the circular economy.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5This utility model provides an embodiment of a waste mud recycling granulation device, including a support frame 1; and a conical granulation shell 2, which is fixedly connected to the support frame 1. A drive assembly is provided below the conical granulation shell 2, and the drive assembly is fixedly connected to the support frame 1. The output end of the drive assembly is fixedly connected to a bottom stirring rod 4, and the drive assembly is used to drive the bottom stirring rod 4 to rotate. The bottom stirring rod 4 is rotatably connected to the conical granulation shell 2. A side mixing assembly is fixedly connected to the conical granulation shell 2, and a blower 11 is fixedly connected to the conical granulation shell 2. An air supply pipe 12 is fixedly connected to the output end of the blower 11, and an annular pipe 13 is fixedly connected to the other end of the air supply pipe 12. The annular pipe 13 is fixedly connected to the conical granulation shell 2. On the granulation shell 2, several jet nozzles 1301 are provided below the annular pipe 13. The jet nozzles 1301 are fixedly connected inside the conical granulation shell 2. The dried slurry is introduced into the conical granulation shell 2, and then the drive component outputs power to the bottom stirring rod 4, causing the bottom stirring rod 4 to rotate. At the same time, the side mixing component also starts to work, so that the slurry circulates and mixes in the conical granulation shell 2 until granulation is completed. After the finished product is discharged from the shell, the blower 11 generates negative pressure to provide a strong airflow to the air supply pipe 12. The air is then transported through the air supply pipe 12 to the annular pipe 13, and then through the annular pipe 13 to each jet nozzle 1301, which sprays onto the inside of the conical granulation shell 2 to remove residual particles on the inner wall and prevent the machine from clogging.
[0024] Please see Figures 1-3In this embodiment, the driving assembly includes a first driving motor 301, a driving gear 302, and a driven gear 303. The first driving motor 301 is fixedly connected to the support frame 1, and its output end is fixedly connected to the driving gear 302. The first driving motor 301 drives the driving gear 302 to rotate. The driven gear 303 is meshed with one side of the driving gear 302. The driven gear 303 is fixedly connected to the bottom stirring rod 4. The first driving motor 301 outputs torque to the driving gear 302, causing the driving gear 302 to rotate, which in turn drives the driven gear 303 meshing with the driving gear 302 to rotate. This, in turn, drives the bottom stirring rod 4 to stir in the conical granulation shell 2 for granulation. The side mixing assembly includes a second driving motor 501 and a side stirring rod 502. The second driving motor 501 is fixedly connected to the conical granulation shell 2. The output end of the second drive motor 501 is fixedly connected to the side stirring rod 502. The second drive motor 501 is used to drive the side stirring rod 502 to rotate. The side stirring rod 502 is rotatably connected to the conical granulation shell 2. The second drive motor 501 outputs torque to the side stirring rod 502, causing the side stirring rod 502 to rotate and generate a large extrusion force on the dry mud, pushing the mud to the top of the conical granulation shell 2, allowing the mud particles to fall along the inclined surface of the conical granulation shell 2, thus achieving cyclic stirring. An adhesive tank 6 is fixedly connected to the conical granulation shell 2, and a booster pump 7 is fixedly connected to the adhesive tank 6. The output end of the booster pump 7 is fixedly connected to an atomizing pipe 8, and the other end of the atomizing pipe 8 is fixedly connected to the conical granulation shell 2. The booster pump 7 generates negative pressure, which transports the adhesive in the adhesive tank 6 to the atomizing pipe 8, and atomizes the adhesive through the atomizing pipe 8, spraying it into the conical granulation shell 2.
[0025] Please see Figures 1-5In this embodiment, a vacuum pump 9 is fixedly connected to the conical granulation shell 2. An extraction pipe 10 is fixedly connected to the output end of the vacuum pump 9, and the other end of the extraction pipe 10 is fixedly connected to the conical granulation shell 2. The vacuum pump 9 generates negative pressure, which is used to extract gas from the conical granulation shell 2 through the extraction pipe 10, allowing the slurry to be automatically drawn into the conical granulation shell 2. A feed pipe 201 is located above the conical granulation shell 2, and a discharge pipe 14 is fixedly connected to the bottom of the conical granulation shell 2. A feeding assembly is fixedly connected to the discharge pipe 14. Dry slurry is fed into the conical granulation shell 2 through the feed pipe 201, and the opening and closing of the discharge pipe 14 is controlled by the feeding assembly. The feeding component for controlling the product feeding includes a hydraulic cylinder 1501, a hydraulic rod 1502, and a sealing piston 1503. The hydraulic cylinder 1501 is fixedly connected to the conical granulation shell 2. The output end of the hydraulic cylinder 1501 is fixedly connected to the hydraulic rod 1502. The hydraulic cylinder 1501 is used to push the hydraulic rod 1502 to move linearly. The other end of the hydraulic rod 1502 is fixedly connected to the sealing piston 1503. The sealing piston 1503 is slidably connected inside the discharge pipe 14. The hydraulic cylinder 1501 outputs pressure to the hydraulic rod 1502, causing the hydraulic rod 1502 to move back and forth linearly, which drives the sealing piston 1503 to move, thereby controlling the discharge of the finished product.
[0026] During operation, a vacuum pump 9 generates negative pressure, which is used to extract gas from the conical granulation shell 2 through the extraction pipe 10. This allows the slurry to be automatically drawn into the feed pipe 201 and then transported into the conical granulation shell 2. The first drive motor 301 outputs torque to the drive gear 302, causing it to rotate. This drives the driven gear 303 meshing with the drive gear 302 to rotate, thereby causing the bottom stirring rod 4 to stir within the conical granulation shell 2. Simultaneously, the second drive motor 501 outputs torque to the side stirring rod 502, causing it to rotate and exert significant pressure on the dry slurry, pushing it upwards towards the conical granulation shell 2. This allows the slurry particles to then move along the inclination of the conical granulation shell 2. The mixture falls and is circulated and stirred. Then, a negative pressure is generated by the booster pump 7, which delivers the adhesive in the adhesive box 6 to the atomizing pipe 8. The adhesive is atomized through the atomizing pipe 8 and sprayed into the conical granulation shell 2 to complete the granulation of waste sludge. Then, the hydraulic cylinder 1501 outputs pressure to the hydraulic rod 1502, causing the hydraulic rod 1502 to shorten and drive the sealing piston 1503 to slide in the discharge pipe 14, opening the discharge pipe 14 and discharging the finished product out of the shell. Then, the blower 11 generates a negative pressure to provide a strong airflow to the air supply pipe 12, which delivers the air to the annular pipe 13, and then to each jet nozzle 1301, spraying it onto the inside of the conical granulation shell 2 to remove residual particles on the inner wall and prevent machine blockage.
[0027] Through the above steps, two stirring rods are used to achieve thorough and uniform mixing inside the device, resulting in a product of good quality that avoids inconsistencies in quality that could affect subsequent use. A blower 11 is also installed in conjunction with an annular pipe 13, using multiple air nozzles 1301 to thoroughly clean the inside of the device, preventing residues and cleaning the gaps in the stirring structure to prevent blockages. This avoids resource waste and is more economical, solving the problems of traditional granulation devices having a simple structure, insufficient mixing, lack of a cleaning structure, shortened device lifespan, and increased production costs.
