Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a solid-liquid separation device for municipal solid waste treatment, comprising a base 22, a support frame 9 fixedly connected to the upper surface of the base 22, a first motor 1 and a crushing box 23 fixedly connected to the upper surface of the support frame 9, a first gear 2 fixedly provided at the output end of the first motor 1, crushing teeth 4 fixedly connected to the outer wall of the first gear 2, the outer wall of the crushing teeth 4 rotatably connected to the inside of the crushing box 23, a second gear 3 meshing with the tooth end of the first gear 2, the outer walls of both the first gear 2 and the second gear 3 rotatably connected to the outer wall of the crushing box 23, a feeding trough 10 fixedly connected to the upper surface of the crushing box 23, a magnet 21 fixedly connected to the outer wall of the feeding trough 10, the outer wall of the feeding trough 10 fixedly connected to the upper surface of the support frame 9, and a feeding assembly provided at the discharge port on the lower surface of the crushing box 23.

[0018] Specifically, the first motor 1 drives the first gear 2 to rotate, which in turn drives the crushing teeth 4 to rotate. The first gear 2 drives the second gear 3 to rotate in opposite directions, which in turn drives the crushing teeth 4 to rotate. The two sets of crushing teeth 4 rotating in opposite directions achieve the effect of crushing and pulverizing household waste. The base 22 supports and fixes the support frame 9 and support legs 20. The support frame 9 supports and fixes the crushing box 23, the feeding trough 10 and the first motor 1. The crushing box 23 supports the feeding trough 10, the first gear 2 and the second gear 3, thus achieving a stable device. Magnets 21 are installed on the outer wall of the feeding trough 10 to attract metal blocks, thus preventing metal blocks from entering the crushing box 23 and preventing jamming during the crushing process, thereby improving the crushing efficiency of household waste.

[0019] Reference Figure 1 and Figure 3 The feeding assembly includes a feeding cylinder 8, a second motor 5 is fixedly connected to the outer wall of the feeding cylinder 8, a fixed rod 7 is fixedly installed at the output end of the second motor 5, an auger blade 6 is fixedly connected to the outer wall of the fixed rod 7, the outer wall of the fixed rod 7 is rotatably connected to the inner wall of the feeding cylinder 8, and the outer wall of the feeding cylinder 8 is fixedly connected to the outer wall of the support frame 9.

[0020] Specifically, the second motor 5 drives the fixed rod 7 to rotate, which in turn drives the auger blade 6 to rotate. The fixed rod 7 supports and fixes the auger blade 6, and the support frame 9 supports and fixes the material transfer cylinder 8. In turn, the material transfer cylinder 8 supports and fixes the second motor 5 and supports the fixed rod 7, thus achieving a more stable sliding effect of the fixed rod 7 on the inner wall of the material transfer cylinder 8.

[0021] Reference Figure 1 and Figure 4 A support leg 20 is fixedly connected to the upper surface of the base 22, and a cylindrical shell 15 is fixedly connected to the upper surface of the support leg 20. An L-shaped plate 12 is fixedly connected to the upper surface of the cylindrical shell 15, and a third motor 11 is fixedly connected to the inner top wall of the L-shaped plate 12. A cross-shaped fixing frame 13 is fixedly installed at the output end of the third motor 11. The outer wall of the cross-shaped fixing frame 13 is rotatably connected to the inner top wall of the cylindrical shell 15, and a rotating drum 14 is fixedly connected to the outer wall of the cross-shaped fixing frame 13. The bottom end of the rotating drum 14 is rotatably connected to the inner wall of the cylindrical shell 15, and a discharge valve 19 is connected through the bottom end of the cylindrical shell 15. The interior of the rotating drum 14 is rotatably connected through the outer wall of the discharge valve 19, and a water outlet valve 18 is fixedly connected through the interior of the cylindrical shell 15.

[0022] Specifically, the third motor 11 drives the cross-shaped fixing frame 13 to rotate, which in turn drives the rotating drum 14 to rotate. The cylindrical outer shell 15 supports the rotating drum 14 and is fixed to the third motor 11 by the L-shaped plate 12. The support legs 20 also support and fix the cylindrical outer shell 15. The rapid rotation of the rotating drum 14 causes the liquid in the crushed household waste to be thrown out of the rotating drum 14 and into the cylindrical outer shell 15, achieving the effect of solid-liquid separation of the crushed household waste. At the same time, the water outlet valve 18 is opened to discharge the liquid. After the solid-liquid separation is completed, the centrifugal force of the material is changed by rapidly rotating the rotating drum 14 in the opposite direction, which breaks the adhesion between the material and the inner wall of the rotating drum 14, thereby achieving the effect of material detachment. At the same time, the discharge valve 19 is opened to separate and discharge the material. The rotating drum 14 is slidably connected to the discharge valve 19, which does not affect the rotation of the rotating drum 14 or the opening and closing of the discharge valve 19, and therefore does not affect the discharge of the discharge valve 19.

[0023] Reference Figure 4 A scraper 16 and a cleaning brush 17 are fixedly connected to the inner wall of the cylindrical outer shell 15, and the outer walls of the scraper 16 and the cleaning brush 17 are slidably connected to the outer wall of the drum 14.

[0024] Specifically, during the operation of the drum 14, the scraper 16 and the cleaning brush 17 can clean the outer wall and holes of the drum 14, thereby preventing blockage. The cylindrical outer shell 15 serves to support and fix the scraper 16 and the cleaning brush 17.

[0025] Working principle: First, the household waste to be processed is placed into the feeding trough 10. The metal in the household waste is discharged by the magnet 21, and then the household waste enters the crushing box 23. Then, the first motor 1 is started, and the first gear 2 is driven to rotate. The first gear 2 drives the crushing teeth 4 to rotate. Through the meshing connection of the first gear 2 and the second gear 3, the second gear 3 rotates in the opposite direction, and thus drives the crushing teeth 4 to rotate. Through the opposite rotation of the two sets of crushing teeth 4, the household waste is squeezed and crushed. Then, the crushed household waste is discharged into the conveying cylinder 8 through the discharge port on the lower surface of the crushing box 23. Then, the second motor 5 is started, and the second motor 5 drives the fixed rod 7 to rotate. The fixed rod 7 drives the auger blade 6 to rotate, thus sending the crushed household waste into the rotating drum 14. Then, the third motor 11 is started, which drives the cross-shaped fixing frame 13 to rotate, and in turn, the cross-shaped fixing frame 13 drives the rotating drum 14 to rotate. Through the rapid rotation of the rotating drum 14, the pulverized domestic waste is separated into solid and liquid. At the same time, the water outlet valve 18 is opened to discharge the liquid. During the rotation, the rotating drum 14 is cleaned by the scraper 16 and the cleaning brush 17 to prevent the holes of the rotating drum 14 from becoming clogged. After the work is completed, the discharge valve 19 is opened to discharge the processed domestic waste.
