[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a highly corrosion-resistant metal tank device for sewage treatment, comprising:

[0032] Wastewater treatment tank 1 is equipped with a mixing mechanism. It should be noted that during the addition of disinfectant, the disinfectant can be fully mixed with the wastewater, and then the disinfectant and wastewater can be further mixed thoroughly to improve wastewater treatment efficiency.

[0033] The mixing mechanism includes a sterilization and disinfection agent tank 2, a material pump 3, a discharge pipe 7, a conduit 12, a valve plate 14, a rotating shaft 15, a square plate 16, a top plate 17, a torsion spring 18, a bevel gear 19, and a bevel gear 20.

[0034] The pump 3 is fixedly installed on the sewage treatment tank 1, the sterilization and disinfection agent tank 2 is fixedly installed on the top of the sewage treatment tank 1, the discharge pipe 7 is fixedly installed on the pump 3 and the sewage treatment tank 1, and the conduit 12 is fixedly installed on the sterilization and disinfection agent tank 2 and the discharge pipe 7. It should be noted that the sterilization and disinfection agent tank 2 contains sterilization and disinfection agents.

[0035] Valve plate 14 is rotatably mounted on conduit 12, rotating shaft 15 is rotatably mounted on sewage treatment tank 1, square plate 16 is fixedly mounted on rotating shaft 15, top plate 17 is fixedly mounted on top of rotating shaft 15, torsion spring 18 is fixedly mounted between top plate 17 and sewage treatment tank 1, bevel gear 19 is fixedly mounted on top plate 17, bevel gear 20 is fixedly mounted on valve plate 14, and bevel gear 19 and bevel gear 20 mesh with each other.

[0036] With the above structure, sewage is first added into sewage treatment tank 1, and pump 3 and solenoid valve 9 are started. This allows sewage to be drawn from the bottom of sewage treatment tank 1 and discharged through discharge pipe 7. The sewage discharged from discharge pipe 7 impacts square plate 16, causing square plate 16 to rotate at a certain angle. Square plate 16 drives shaft 15 to rotate, shaft 15 drives top plate 17 to rotate, top plate 17 compresses torsion spring 18, top plate 17 drives bevel gear 19 to rotate, which in turn causes valve plate 14 to rotate. This allows disinfectant in disinfectant tank 2 to enter discharge pipe 7 through conduit 12, so that disinfectant and sewage are mixed and impacted together on square plate 16. In this way, sewage and disinfectant are initially mixed and treated.

[0037] Specifically, the mixing mechanism also includes a material extraction pipe 4, a connecting pipe 5, a material extraction head 6, a branch pipe 8, a solenoid valve 9, a solenoid valve 10, and a discharge head 11. The material extraction pipe 4 is fixedly installed on the material extraction pump 3 and the sewage treatment tank 1. The connecting pipe 5 is fixedly connected to the material extraction pipe 4. The material extraction head 6 is fixedly installed on the connecting pipe 5. The branch pipe 8 is fixedly installed on the discharge pipe 7. The solenoid valve 9 and the solenoid valve 10 are respectively installed on the discharge pipe 7 and the branch pipe 8. The discharge head 11 is fixedly installed on the branch pipe 8.

[0038] With the above structure, after a certain amount of sterilizing and disinfecting agent is added, the solenoid valve 19 is closed and the solenoid valve 210 is opened. At this time, the valve plate 14 closes the conduit 12. At this time, the pump 3 draws out the sewage below the sewage treatment tank 1 and discharges it through the discharge head 11 on the branch pipe 8. After working for a period of time, the sewage and sterilizing and disinfecting agent can be fully mixed, thereby improving the sewage treatment efficiency.

[0039] Specifically, a weathering steel plate is fixedly installed on the inner wall of the sewage treatment tank 1. It should be noted that the weathering steel plate has the characteristics of high-quality steel such as wear resistance and fatigue resistance. While improving the structural stability of the sewage treatment tank 1, it can also prevent the sewage treatment effect of the treatment equipment from being affected by the corrosion of the inner wall.

[0040] Specifically, a one-way valve 13 is installed on the conduit 12, and the conduit 12 is internally connected to the discharge pipe 7. It should be noted that the one-way valve 13 is designed to prevent sewage from passing through.

[0041] Specifically, an addition pipe is fixedly installed on the top of the sewage treatment tank 1, a support frame is fixedly installed at the bottom of the sewage treatment tank 1, and a drain pipe is fixedly installed on the sewage treatment tank 1. A valve is installed on the drain pipe to facilitate the addition and discharge of sewage.

[0042] Working principle:

[0043] S1: When the equipment is put into operation, the operator first injects sewage into the sewage treatment tank 1 through the addition pipe, and then starts the suction pump 3. The suction pump 3 starts to work and uses its own suction to draw out the sewage from the bottom of the sewage treatment tank 1. The sewage flows through the suction pipe 4 and the connecting pipe 5 in sequence, and finally enters the discharge pipe 7 through the suction head 6. At this time, if the solenoid valve 1 9 is in the open state and the solenoid valve 2 10 is in the closed state, the sewage will be discharged directly along the discharge pipe 7.

[0044] S2: The sewage discharged from the discharge pipe 7 has a certain flow velocity and impact force, which impacts the square plate 16 fixed on the rotating shaft 15. The square plate 16 is subjected to the impact force of the water flow, which drives the rotating shaft 15 to start rotating around its axis. When the rotating shaft 15 rotates, the top plate 17 at the top rotates accordingly. During the rotation, the top plate 17 compresses the torsion spring 18 sleeved on the rotating shaft 15. The torsion spring 18 generates elastic deformation and accumulates elastic potential energy. The bevel gear 19 fixedly installed on the top plate 17 rotates synchronously with the top plate 17. Since the bevel gear 19 meshes with the bevel gear 20 on the valve plate 14, the rotation of the bevel gear 19 is driven by the gear meshing transmission, which drives the bevel gear 20 to rotate. The rotation of the bevel gear 20 causes the valve plate 14 to rotate around its rotating shaft on the guide tube 12. The valve plate 14, which was originally closed to the guide tube 12, gradually opens.

[0045] S3: When the valve plate 14 is opened, the disinfectant in the disinfectant tank 2 located at the top of the sewage treatment tank 1 flows into the discharge pipe 7 through the conduit 12 under the action of gravity, and mixes with the sewage flowing in the discharge pipe 7. During this process, the one-way valve 13 installed on the conduit 12 can prevent sewage from flowing back into the disinfectant tank 2, ensuring the accuracy and purity of the agent addition. At the same time, the elastic force generated by the torsion spring 18 and the water flow impact force form a dynamic balance, so that the valve plate 14 maintains a relatively stable opening, realizing the quantitative addition of the agent.

[0046] S4: After the valve plate 14 is opened and the agent is injected into the discharge pipe 7, the wastewater mixed with the agent continues to be discharged from the discharge pipe 7, impacting the square plate 16 again, forming a preliminary stirring and mixing effect, so that the agent is initially dispersed in the wastewater. After adding a certain amount of sterilizing and disinfecting agent, the operator closes the solenoid valve 19 and opens the solenoid valve 20. At this time, the wastewater pumped by the pump 3 is no longer discharged directly from the discharge pipe 7, but is discharged from the discharge head 11 through the branch pipe 8 on the discharge pipe 7. The discharge head 11 is designed to be inclined downward and circumferentially distributed, so that when the wastewater is sprayed from the discharge head 11, it forms a spiral upward vortex in the wastewater treatment tank 1. This vortex motion can stir the wastewater in all directions and at multiple angles, so that the agent and wastewater can fully contact and mix, greatly improving the mixing effect and reaction efficiency. Under the action of the vortex, the wastewater continuously circulates. After multiple cycles, the agent and wastewater are evenly mixed, completing the core process of wastewater treatment.

[0047] The above provides a detailed description of a highly corrosion-resistant metal tank device for wastewater treatment. Specific embodiments have been used to illustrate the principles and implementation methods of this invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concepts of this invention. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
