Description

Technical Field

[0001] This utility model is a rapid sedimentation device for wastewater solidification agents, belonging to the field of sedimentation tank technology. Background Technology

[0002] Sedimentation tanks are structures that remove suspended solids from water through sedimentation. They are water purification devices that utilize the natural sedimentation or coagulation sedimentation of water to remove suspended solids. Solidifying agents are substances that can transform harmful substances in wastewater into stable, non-migrating forms through physical or chemical processes. They play a role in wastewater treatment by reducing the toxicity of pollutants, minimizing environmental risks, and enabling resource utilization.

[0003] In most existing rapid sedimentation devices for wastewater solidification agents, the solidification agent is added through the top opening of the sedimentation device. This method of addition results in a concentrated addition of the solidification agent, which is not conducive to rapid mixing with wastewater. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rapid sedimentation device for wastewater solidification agents.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A rapid sedimentation device for wastewater solidification includes a sedimentation tank. A rotating component is rotatably connected to the top of the sedimentation tank. The bottom end of the rotating component extends into the sedimentation tank and is connected to a stirring shaft. Several stirring rods are evenly connected to the outer surface of the stirring shaft. A stirring mechanism that cooperates with the stirring shaft is provided at the top of the sedimentation tank. A flow cavity is opened inside the stirring shaft. A cavity and a flow pipe are opened inside the stirring rod. A through hole in the middle of the rotating component communicates with the flow cavity. An outlet is opened at the end of the stirring rod away from the stirring shaft.

[0021] See Figure 1-5 The stirring mechanism includes a gear ring 7 fixedly connected to the outer surface of the rotating part 6. A drive motor 8 is fixedly connected to one side of the top of the sedimentation tank 1. The output end of the drive motor 8 is connected to a drive gear 9. The side of the drive gear 9 meshes with the gear ring 7. Through the design of the stirring mechanism, the stirring mechanism drives the stirring shaft 2 and several stirring rods 3 to rotate. The stirring rods 3 rotate in the sedimentation tank 1, thereby accelerating the mixing and stirring of sewage and solidifying agent and accelerating the sedimentation effect.

[0022] See Figure 1-5 The pressing assembly includes a pressure plate 13 located inside the drug cylinder 12. An electric telescopic rod 14 is provided at the top inner part of the bracket 23. The output end of the electric telescopic rod 14 passes through the drug cylinder 12 and is connected to the top of the pressure plate 13. The rotary joint 11 has a hollow structure. The top end of the rotary joint 11 is connected to the drug cylinder 12, and the bottom end of the rotary joint 11 is connected to the through hole in the middle of the rotating part 6. A liquid inlet is provided on the side of the drug cylinder 12. A threaded cap 15 is threadedly connected to the liquid inlet. Through the design of the pressing assembly, it is convenient to introduce the curing agent in the drug cylinder 12 into the sedimentation tank 1.

[0023] See Figure 1-5The sealing assembly includes two U-shaped tubes 18 symmetrically arranged on the flow tube 16 near the end of the cavity 5. The other ends of the two U-shaped tubes 18 are connected to the outlet 17. The flow tube 16 is inclined, with the end of the flow tube 16 near the cavity 5 at the lower end and the end of the flow tube 16 near the outlet 17 at the higher end. An iron ball 19 is provided inside the flow tube 16. Magnets 20 are provided on both sides of the end of the flow tube 16 near the cavity 5. The iron ball 19 cooperates with the magnets 20. A maintenance cover 21 is provided on one end of the surface of the flow tube 16. The maintenance cover 21 is connected to the flow tube 16 by screws 22. Through the design of the sealing assembly, when it is necessary to add curing agent, the sealing assembly can be opened to seal the U-shaped tubes 18, so that the curing agent can be sprayed out through the U-shaped tubes 18 and the outlet 17. When it is not necessary to add curing agent, the sealing assembly can be driven to seal the U-shaped tubes 18.

[0024] See Figure 1-5 The end of the flow pipe 16 is spherical. The bottom of the sedimentation tank 1 is provided with a discharge pipe 10, and a solenoid valve is provided on the discharge pipe 10.

The electric telescopic rod 14, the drive motor 8, the control switch, and the solenoid valve are all electrically connected to the controller. The end of the flow pipe 16 is spherical, which is adapted to the shape of the iron ball 19, so that the iron ball 19 can fall to the end of the flow pipe 16 under the action of gravity to seal the openings of the two U-shaped pipes 18.

[0025] The circuits, electronic components, controllers, and modules involved are all existing technologies that can be fully implemented by those skilled in the art, so there is no need to elaborate. The content protected by this application does not involve any improvement to the software and methods.

[0026] In use, wastewater is introduced into the sedimentation tank 1 through the feed pipe 24 at the top of the sedimentation tank 1. Then, the electric telescopic rod 14 and the drive motor 8 are started. The output end of the electric telescopic rod 14 drives the pressure plate 13 to move. As the pressure plate 13 moves downward, the curing agent in the agent cylinder 12 can be pressed into the through hole in the rotating part 6 through the rotary joint 11. Then it flows into the flow chamber 4 and into the cavity 5. Then it flows into the flow pipe 16, passes through the U-shaped pipe 18 and is sprayed out through the outlet 17. The drive motor 8 rotates and drives the drive gear 9 to rotate. The drive gear 9 rotates and drives the toothed ring 7 that meshes with it to rotate. The toothed ring 7 rotates and drives the rotating part 6 to rotate. The rotating part 6 rotates and drives the stirring shaft 2 and the stirring rod 3 to rotate. With the rotation of the stirring rod 3, it is easy to spray the curing agent evenly and mix the curing agent and wastewater evenly. After the wastewater and curing agent are mixed, the mixture inside the sedimentation tank 1 can be discharged by starting the solenoid valve on the discharge pipe 10. When adding curing agent to the settling tank 1 is stopped, the operation of the electric telescopic rod 14 can be stopped. At this time, under the action of gravity, the iron ball 19 falls and lands near the end of the cavity 5. The design of the magnet 20 can improve the stability of the iron ball 19 when it is located inside the flow tube 16 and blocks the opening of the U-shaped tube 18. The end of the flow tube 16 is a spherical structure that matches the shape of the iron ball 19, making it easy for the iron ball 19 to fall to the end of the flow tube 16 under the action of gravity, which can block the openings of the two U-shaped tubes 18 inside the flow tube 16.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
