[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1 to 4 As shown, this embodiment provides a solid waste treatment water recycling system, including a pretreatment tank 1. A sewage treatment tank 8 is connected to the bottom of the pretreatment tank 1 through a second sewage pipe 9. A water supply component is connected to the bottom of the sewage treatment tank 8 for supplying water to the pretreatment tank 1. A cement separation tank 14 is installed inside the sewage treatment tank 8. A vibrating screen 10 is installed above the cement separation tank 14. A fine impurity treatment tank 12 is installed at the lower end of the vibrating screen 10. A purifier 17 is connected to the bottom of the cement separation tank 14 through a water supply pipe 16. The purifier 17 is connected to the water supply component.

[0026] In use, the pretreatment tank 1 is filled with water, and the garbage is poured in. Metal waste settles to the bottom naturally, while lighter waste floats on the surface, completing the separation. After a period of use, a large amount of sludge and particulate matter will mix with the water. This wastewater is then passed through the second drain pipe 9 into the wastewater treatment tank 8. First, the particulate matter is separated by the vibrating screen 10. The remaining wastewater is then passed into the cement separation tank 14, where the sludge and water are separated. This prevents sludge from accumulating in the pipes and causing blockages. Furthermore, the separated sludge can be further processed, improving work efficiency. This invention achieves preliminary water recycling during garbage disposal through the pretreatment tank 1, wastewater treatment tank 8, water supply assembly, cement separation tank 14, and purifier 17. It separates and treats the particulate matter and sludge mixed in the water, reducing the possibility of pipe blockages, saving maintenance costs, and extending the system's lifespan. Simultaneously, the system possesses the overall function of collecting, treating, and reusing water used in garbage disposal.

[0027] Further refining the solution, a floating debris treatment device 2 and a metal treatment device 3 are respectively installed on one side of the pretreatment tank 1. A water supply component is connected to both the floating debris treatment device 2 and the metal treatment device 3. The atomized water sprayed by the water supply component absorbs the dust generated in the floating debris treatment device 2 and the metal treatment device 3. Floating debris is retrieved using external retrieval equipment and sent to the floating debris treatment device 2, while metal waste is sent to the metal treatment device 3 using external magnetic suction equipment. The waste is then sorted and processed. The atomized water sprayed by the water supply component absorbs the dust generated in both treatment devices, effectively reducing the spread of dust during waste treatment, improving the working environment, reducing the impact of dust on the health of operators, and preventing dust pollution of the surrounding environment.

[0028] Further refining the solution, the water supply component includes a water pump 7. One side of the water pump 7 is connected to the purifier 17, and the other side of the water pump 7 is connected to a water supply pipe 4. The water supply pipe 4 is connected to the floating debris treatment device 2 and the metal treatment device 3 respectively, and sprays water into them. The water supply pipe 4 sprays water into the interior of the floating debris treatment device 2 and the metal treatment device 3 to remove dust, reducing dust emissions and environmental pollution.

[0029] The design is further refined so that the water supply pipe 4 is connected to the water injection pipe 5, with the end of the water injection pipe 5 facing the pretreatment tank 1. A valve is installed at the connection between the water injection pipe 5 and the water supply pipe 4. The valve allows water to be injected into the pretreatment tank 1 as needed, making it easy to replenish water and increasing the system's flexibility and practicality.

[0030] Further refining the scheme, the bottoms of the metal treatment device 3 and the floating matter treatment device 2 are each connected to a first drain pipe 6. The bottom of the first drain pipe 6 extends into the wastewater treatment tank 8 and is located above the vibrating screen 10. Solenoid valves are installed in both the first drain pipe 6 and the second drain pipe 9. Dust generated by the two treatment devices is absorbed by atomized water and flows into the bottom of the two devices, then is discharged through the first drain pipe 6. The solenoid valves enable automatic control of the discharge process, opening or closing the drain pipes as needed, thus improving the system's automation level and operating efficiency.

[0031] Further refining the design, the cement separation box 14 is equipped with a water storage chamber 18, a sludge storage chamber 19, and a drive chamber 22. A separation plate 20 is installed above the water storage chamber 18, and a drive shaft 21 is fixedly connected to the bottom of the separation plate 20. A motor 23 is fixedly connected to the bottom of the drive shaft 21, and the motor 23 is located inside the drive chamber 22. Wastewater falls from the vibrating screen 10 onto the separation plate 20. The rapid rotation of the separation plate 20 throws large particles and sludge into the sludge storage chamber 19, while water is thrown into the water storage chamber 18. The rapid rotation of the separation plate 20, driven by the motor 23, throws large particles and sludge from the wastewater onto the separation plate 20 into the sludge storage chamber 19, while water is thrown into the water storage chamber 18. This separation method utilizes the principle of centrifugal force, which can efficiently separate mud and water from wastewater, improving the efficiency and quality of wastewater treatment and providing more favorable conditions for subsequent water purification.

[0032] Further refining the scheme, a planetary gear set 24 is also fixedly connected to the drive shaft 21. The planetary gear set 24 is located in the drive cavity 22. A first strong magnet 25 is fixedly installed on one side of the top surface of the planetary gear set 24. The first strong magnet 25 is magnetically connected to a second strong magnet 26. The second strong magnet 26 is located in the sludge storage cavity 19. A scraper 27 is fixedly connected to the top surface of the second strong magnet 26. A sludge outlet 29 is opened on the bottom side wall of the cement separation box 14. A flexible plate 30 is provided at the sludge outlet 29. The scraper 27 is used to scrape the sludge in the sludge storage cavity 19. When the scraper 27 contacts the flexible plate 30, the sludge is shaken by the flexible plate 30 and discharged from the sludge outlet 29. After scraping off the sludge, the scraper 27 comes into contact with the flexible plate 30. The flexible plate 30 scrapes off the sludge on the scraper 27 and discharges the sludge from the sludge outlet 29 by shaking. This avoids the sludge from accumulating in the sludge storage chamber 19 and affecting the separation effect, ensuring the continuous and stable operation of the cement separation box 14. At the same time, the magnetic connection and the shaking of the flexible plate 30 make the sludge discharge smoother.

[0033] Further refining the design, rollers 28 are installed on the side wall of scraper 27, and an annular groove is provided on the outer wall of water storage chamber 18. Rollers 28 are located in the annular groove and are slidably connected to it. The arrangement of the annular groove and rollers 28 provides stable support and guidance for the movement of scraper 27, reduces friction and shaking during the movement of scraper 27, ensures that scraper 27 can smoothly and accurately scrape the sludge in sludge storage chamber 19, and improves the reliability and service life of the equipment.

[0034] Further refining the design, a water collection hood 13 is installed above the cement separation tank 14, located below the vibrating screen 10. A receiving plate 11 is located at the lower end of the vibrating screen 10, with its lower end positioned above the fine impurity treatment tank 12. The water collection hood 13 collects water falling from the vibrating screen 10, preventing water loss and improving water recovery rate. The receiving plate 11 guides the residual impurities screened out by the vibrating screen 10 to the fine impurity treatment tank 12 for further processing, enabling the entire system to effectively separate and treat impurities of different particle sizes, thus improving the comprehensiveness of wastewater treatment.

[0035] Further refining the design, a sludge conveying mechanism 15 is installed on the side of the cement separation tank 14 furthest from the purifier 17. The sludge separated from the cement separation tank 14 enters the sludge conveying mechanism 15, where an auger compresses and transports the sludge. This centralized treatment and transport of sludge, combined with the auger's compression action, reduces the volume of the sludge, facilitating subsequent transportation and disposal. It also better integrates the entire water circulation system with the sludge treatment process, improving the overall efficiency of waste treatment.
