Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically a solid-liquid separation device for waste collection and transportation. Background Technology

[0002] Garbage is solid waste generated in human daily life and production. Due to its large volume, complex and diverse composition, and its polluting, resource-intensive, and social characteristics, if it is not properly handled, it will pollute the environment, affect environmental sanitation, waste resources, undermine production and living safety, and disrupt social harmony. In the garbage disposal process, solid-liquid separation devices are needed to separate the collected garbage, thereby facilitating subsequent fine processing.

[0003] The published patent document CN213767307U discloses a solid-liquid separation device for garbage collection. This patent document uses a first motor to drive a connecting shaft to rotate. As the radius of the connecting shaft gradually increases, in conjunction with the rotation of the spiral blades, the garbage is squeezed and drained during the conveying process. The wastewater in the garbage falls into the bottom of the fixed base through the water-permeable holes. In conjunction with the conical cylinder fixedly installed at the end of the separation cylinder, the intensity of the garbage being squeezed is increased, further improving the solid-liquid separation efficiency. The aforementioned patent document uses conveying and squeezing solid-liquid separation and compression solid-liquid separation. However, the aforementioned patent document cannot perform conveying and squeezing solid-liquid separation during compression solid-liquid separation, and the two solid-liquid separations cannot be performed simultaneously, resulting in low solid-liquid separation efficiency for the garbage.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-2 This utility model provides a solid-liquid separation device for garbage collection, including a support platform 1, a conveying cylinder 2 mounted on the support platform 1, and a vertical pipe 3 passing through and fixedly installed on the support platform 1. The conveying cylinder 2 is connected to the vertical pipe 3, and a feed hopper 27 is connected to the top of the conveying cylinder 2. A conveying motor 4 is fixedly installed on one side of the conveying cylinder 2, and a conveying shaft 15 is rotatably mounted inside the conveying cylinder 2. One end of the conveying shaft 15 is fixedly installed to the output end of the conveying motor 4, and a spiral blade 16 matching the conveying cylinder 2 is fixedly installed on the outer wall of the conveying shaft 15. A hydraulic cylinder 5 is fixedly installed on the top of the support platform 1. A support rod 6 is fixedly installed on the output end of the hydraulic cylinder 5. A connecting shaft 7 is fixedly installed on the bottom of the support rod 6. A matching compression cylinder 18 and a disc 19 are provided inside the vertical pipe 3. A discharge motor 8 is fixedly installed on the outer wall of the vertical pipe 3. The lower end of the connecting shaft 7 is fixedly installed on the top of the compression cylinder 18. A rotating shaft 20 is connected through the middle of the disc 19 with an interference fit. One end of the rotating shaft 20 is fixedly installed on the output end of the discharge motor 8. The rotating shaft 20 is rotatably installed with the vertical pipe 3. In this technical solution, waste is conveyed into the conveying cylinder 2 through the feeding hopper 27. The conveying motor 4 drives the conveying shaft 15 and the spiral blades 16 to rotate and convey the waste. The compression cylinder 18 blocks the waste from entering the vertical pipe 3, thus conveying and compressing the waste to achieve primary solid-liquid separation. Then, the hydraulic cylinder 5 drives the support rod 6 to move upward. The support rod 6 drives the compression cylinder 18 to move upward through the connecting shaft 7, releasing the obstruction of the waste. The waste separated in the first step enters the vertical pipe 3. Then, the hydraulic cylinder 5, the support rod 6, and the connecting shaft 7 drive the compression cylinder 18 to move downward, compressing the waste in the vertical pipe 3 for secondary solid-liquid separation. Finally, the unloading motor 8 drives the rotating shaft 20 and the disc 19 to rotate, thereby discharging the compressed waste. This not only improves the separation effect but also allows the two solid-liquid separations to be carried out simultaneously, increasing the efficiency of solid-liquid separation of waste.

[0017] In some technical solutions, such as Figure 1-2 and Figure 4-5 As shown, the bottom of the conveying cylinder 2 is provided with several drainage holes 17 at equal intervals, and a collection tank 9 is fixedly installed at the bottom of the conveying cylinder 2. The drainage holes 17 are connected to the interior of the collection tank 9. The bottom of the collection tank 9 is connected to a vertical pipe 11. The outer wall of the vertical pipe 3 is provided with drainage holes 25, and a collection tank 10 is fixedly installed on the outer wall of the vertical pipe 3. The drainage holes 25 are connected to the interior of the collection tank 10, and the bottom inner wall of the drainage holes 25 is at the same height as the top of the disc 19. The bottom of the collection tank 10 is connected to an L-shaped pipe 12, which is connected to the vertical pipe 11.

[0018] In use, the water from the first solid-liquid separation can flow into the first collection tank 9 through the drain hole 17, and the water from the second solid-liquid separation can flow into the second collection tank 10 through the drain hole 25. Finally, the water from the solid-liquid separation is discharged through the vertical pipe 11 and the L-shaped pipe 12.

[0019] In some technical solutions, such as Figure 1 and Figure 3 As shown, sleeves 21 are fixedly connected to the front and rear sides of the top of the support platform 1, and connecting rods 22 are fixedly connected to the front and rear sides of the support rod 6. A limiting shaft 23 matching the sleeve 21 is fixedly installed at the bottom of the connecting rod 22, and the lower end of the limiting shaft 23 is inside the sleeve 21.

[0020] During use, the limiting action of the limiting shaft 23 and the sleeve 21 ensures the stability of the hydraulic cylinder 5 in moving and compressing the cylinder 18.

[0021] In some technical solutions, such as Figure 4-5 As shown, a matching filter screen 24 is fixedly installed inside the drain hole 17, and a matching filter screen 26 is fixedly installed inside the drain hole 25.

[0022] During use, filter screen 24 and filter screen 26 prevent debris from entering drain hole 17 and drain hole 25, thus not affecting the discharge of water from the solid-liquid separation.

[0023] In some technical solutions, such as Figure 1 As shown, several L-shaped support rods 13 are symmetrically fixedly installed on the front and rear sides of the conveying cylinder 2, and the lower end of the L-shaped support rods 13 is fixedly installed on the top of the support platform 1.

[0024] In use, the L-shaped support rod 13 provides an installation fulcrum for the conveying cylinder 2.

[0025] In some technical solutions, such as Figure 1 As shown, several support legs 14 are fixedly installed at equal intervals along the outer edge of the bottom of the support platform 1, and anti-slip pads are provided at the lower ends of the support legs 14.

[0026] When in use, the anti-slip pads at the lower end of the support legs 14 increase the stability of the device.

[0027] Working principle: During operation, waste is conveyed into the conveying cylinder 2 through the feed hopper 27. The conveying motor 4 drives the conveying shaft 15 and the spiral blades 16 to rotate and convey the waste. The compression cylinder 18 blocks the waste from entering the vertical pipe 3, thus conveying and squeezing the waste to achieve solid-liquid separation. The hydraulic cylinder 5 then drives the support rod 6 to move upward. The support rod 6, through the connecting shaft 7, drives the compression cylinder 18 to move upward, releasing the obstruction of the waste. The separated waste then enters the vertical pipe 3 and is further conveyed by the hydraulic cylinder 5... The support rod 6 and the connecting shaft 7 drive the compression cylinder 18 to move downwards, compressing the waste in the vertical pipe 3 and performing secondary solid-liquid separation. Then, the unloading motor 8 drives the rotating shaft 20 and the disc 19 to rotate, thereby discharging the compressed waste. The two solid-liquid separations can be performed simultaneously. The first drain hole 17 allows the water from the first solid-liquid separation to flow into the first collection tank 9, and the second drain hole 25 allows the water from the second solid-liquid separation to flow into the second collection tank 10. Finally, the water from the solid-liquid separation is discharged through the vertical pipe 11 and the L-shaped pipe 12.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
