DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Example: Figure 1-3 As shown, a multifunctional sludge drying device comprises a bottom plate 1, a lifting assembly is arranged on the left side of the top of the bottom plate 1, a hinge seat 10 is fixedly connected to the right side of the top of the bottom plate 1, a sludge drying device body 3 is hingedly connected to the top of the hinge seat 10, a connecting seat 4 is fixedly connected to the left end of the sludge drying device body 3, and the connecting seat 4 is fixedly connected to the output end of the lifting assembly, a stirring assembly is arranged inside the sludge drying device body 3, a scraping ring 11 is slidably connected inside the sludge drying device body 3, a pair of second motors 13 are fixedly connected to the right end of the sludge drying device body 3, the pair of second motors 13 are connected to the same controller and can work at the same time, the output ends of the pair of second motors 13 are fixedly connected to threaded rods 12, the pair of threaded rods 12 are threadedly connected to the scraping ring 11, and the outer side surface of the scraping ring 11 fits the inside of the sludge drying device body 3;

[0022] After the sludge is dried in the sludge drying device body 3, the lifting component works to lift the left end of the sludge drying device body 3, and the sludge drying device body 3 rotates around the hinge seat 10 to open the discharge port, and the dried sludge is discharged from the discharge port. When the sludge outflow speed is significantly reduced, a pair of second motors 13 work to drive a pair of threaded rods 12 to rotate, and the rotating pair of threaded rods 12 drive the scraper ring 11 to move toward the discharge port inside the sludge drying device body 3 through the thread. The scraper ring 11 concentrates the sludge adhered to the inner wall of the sludge drying device body 3 toward the discharge port, so that the sludge in the sludge drying device body 3 is discharged as much as possible, thereby improving the sludge discharge effect.

[0023] Specifically, Figure 1 As shown, the lifting assembly includes a first motor 5 and a column 8. The first motor 5 is fixedly connected to the top of the base plate 1. The output end of the first motor 5 is fixedly connected to a take-up wheel 6. A rope 7 is wound around the outside of the take-up wheel 6. The column 8 is fixedly connected to the top of the base plate 1. The top of the column 8 is rotatably connected to a fixed pulley 9, and the rope 7 passes through the fixed pulley 9 and is fixedly connected to the connecting seat 4. A worm gear reducer is arranged inside the first motor 5. The first motor 5 drives the take-up wheel 6 to rotate when it works. The rotating take-up wheel 6 winds the rope 7 around the outside of the take-up wheel 6, so that the height of the movable end of the rope 7 becomes higher, thereby lifting the left side of the sludge drying device body 3.

[0024] Specifically, Figure 2 and Figure 3 As shown, the stirring assembly includes a rotating shaft 14, and the rotating shaft 14 is rotatably connected to the inside of the sludge drying device body 3, and multiple groups of connecting pipes 15 are fixedly connected to the outside of the rotating shaft 14. A stirring rod 19 is slidably connected to the inside of the connecting pipe 15. The right end of the sludge drying device body 3 is fixedly connected to a third motor 20, and the output end of the third motor 20 is fixedly connected to a driving gear 21, and the outer side of the driving gear 21 is meshingly connected to a driven gear 22, and the driven gear 22 is fixedly connected to the right end of the rotating shaft 14. The connecting pipe 15 and the stirring rod 19 have the same structure as the piston rod. The third motor 20 drives the driving gear 21 to rotate when it works, and the driving gear 21 drives the rotating shaft 14 to rotate through the driven gear 22, thereby causing the connecting pipe 15 and the stirring rod 19 to rotate inside the sludge drying device body 3 to stir the sludge.

[0025] Specifically, Figure 2 As shown, the interior of the rotating shaft 14 is a hollow structure, and the connecting pipe 15 is connected to the interior of the rotating shaft 14. The right end of the rotating shaft 14 is rotatably connected to the connecting head 18, and the right end of the connecting head 18 is fixedly connected to the hose 17. A hydraulic press 16 is provided at the bottom of the hose 17, and the hydraulic press 16 is fixedly connected to the top right side of the bottom plate 1. The hydraulic press 16 works to send hydraulic oil into the interior of the rotating shaft 14, and flows into the interior of the connecting pipe 15 along the internal cavity of the rotating shaft 14. As the hydraulic oil flows in, the stirring rod 19 is pushed out of the connecting pipe. 15. The overall length of the connecting pipe 15 and the stirring rod 19 is lengthened, and the operating range of the stirring assembly is improved. In order to prevent the sludge from passing over the scraper ring 11 and reaching the left side of the scraper ring 11 during the process of the scraper ring 11 cleaning the sludge, the scraper ring 11 needs to be thickened, so that the scraper ring 11 and the stirring rod 19 will interfere with each other. When the scraper ring 11 is operating, the hydraulic press 16 will retract the hydraulic oil, so that the stirring rod 19 will retract into the interior of the connecting pipe 15, avoiding the interference between the stirring rod 19 and the scraper ring 11.

[0026] Specifically, Figure 1 and Figure 2As shown, a pair of support seats 2 are fixedly connected to the middle of the top end of the base plate 1, and the top of the support seat 2 is arranged at the bottom of the sludge drying device body 3. The sludge drying device body 3 is supported by the support seat 2, thereby reducing the load on the articulated seat 10 and the lifting assembly.

[0027] Working principle: After the sludge is dried in the sludge drying device body 3, the first motor 5 works to drive the take-up wheel 6 to rotate, and the rotating take-up wheel 6 wraps the rope 7 around the outside of the take-up wheel 6, so that the height of the active end of the rope 7 becomes higher, and then the left side of the sludge drying device body 3 is lifted, and the sludge drying device body 3 rotates around the hinge seat 10 to open the discharge port, and the dried sludge is discharged from the discharge port. When the sludge outflow speed is significantly reduced, the hydraulic press 16 retracts the hydraulic oil, so that the stirring rod 19 retracts into the interior of the connecting pipe 15, and a pair of second motors 13 work to drive a pair of threaded rods 12 to rotate. The rotating pair of threaded rods 12 drive the scraper ring 11 to move toward the discharge port in the interior of the sludge drying device body 3 through the thread, and the scraper ring 11 concentrates the sludge adhering to the inner wall of the sludge drying device body 3 toward the discharge port, so that the sludge in the sludge drying device body 3 is discharged as much as possible.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
