Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, specifically an iron-carbon coupled Fenton treatment device for wastewater. Background Technology

[0002] Coupled Fenton treatment is a common water treatment technology used to treat wastewater containing organic matter. It decomposes organic matter through oxidation, converting it into carbon dioxide, water, and harmless inorganic substances. A reactor is used in Fenton treatment, where wastewater is fed for processing. An existing wastewater Fenton treatment device (publication number: CN218232019U) includes a Fenton treatment tower, an inlet pump, a quantitative dosing device, an ozone generator, and a PLC controller. The upper and lower parts of the Fenton treatment tower are connected by a circulating water pipe with a circulating pump, forming a circulation loop. The inlet pump is connected to the bottom of the Fenton treatment tower via an inlet pipe. The quantitative dosing device includes a reagent tank and a dosing pipe with a dosing pump; the reagent tank is connected to the inlet pipe via the dosing pipe. The ozone generator is connected to the circulation pipe located between the circulating water pump and the Fenton treatment tower. The circulating water pump, inlet pump, dosing pump, and ozone generator are connected to and controlled by the PLC controller.

[0003] While existing devices can complete the Fenton reaction during use, they lack a mechanism for users to weigh iron and carbon powder, thus failing to guarantee the accuracy of iron and carbon addition. Therefore, we propose a device for treating wastewater by coupling iron and carbon with Fenton reaction. Utility Model Content

Detailed Implementation

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

[0024] Please see Figure 1-5 A device for treating wastewater using an iron-carbon coupled Fenton reactor includes a tank 1. A motor 2 is fixedly mounted on the top of the tank 1. A rotating rod 5 is fixedly mounted on the output shaft of the motor 2. A connecting shell 9 is rotatably connected to the bottom end of the rotating rod 5. A connecting rod 19 is fixedly mounted on the bottom end of the rotating rod 5. A circular tube 6 is fixedly mounted on the outer wall of the connecting rod 19. A hopper 8 is connected to the inner wall of the circular tube 6. A stirring rod 7 is fixedly mounted on the outer wall of the circular tube 6. A feeding hopper 3 is fixedly mounted on the top of the tank 1. An installation... The inner wall of the mounting groove 10 is fixedly fitted with a straight rod 11. A weighing spring 12 is sleeved on the outer wall of the straight rod 11. The top of the weighing spring 12 abuts against a receiving hopper 13. A solenoid valve 15 is provided on the inner wall of the receiving hopper 13. A connecting shell 2 14 is provided at the bottom of the receiving hopper 13. A guide pipe 18 is connected inside the connecting shell 2 14. A pressure sensor 16 is fixedly fitted at the bottom of the inner wall of the mounting groove 10. A squeezing rod 17 is fixedly fitted at the bottom of the receiving hopper 13. A discharge pipe 4 passes through the bottom of the tank body 1.

[0025] The above structure, with its tank 1, motor 2, feeding hopper 3, discharge pipe 4, rotating rod 5, circular pipe 6, stirring rod 7, throwing hopper 8, mounting groove 10, straight rod 11, weighing spring 12, and receiving hopper 13, allows the user to directly feed iron and carbon raw materials into the feeding hopper 3 during use. This increases the weight of the receiving hopper 13, causing it to descend along the inner wall of the mounting groove 10, thus achieving the effect of weighing the iron and carbon. This ensures the user's accuracy in adding auxiliary agents and raw materials during wastewater treatment, reduces material waste, guarantees the treatment effect of wastewater, and improves the practicality of the device.

[0026] In a preferred embodiment, the end of the guide tube 18 away from the connecting shell 2 14 is connected to the interior of the connecting shell 1 9, and the throwing hopper 8 is connected to the interior of the connecting shell 2 14 through the connecting shell 1 9.

[0027] In the above structure, the connecting shell 19 and connecting shell 214 are designed so that during operation, the material weighed inside the feeding hopper 3 can enter the circular pipe 6 through the guide pipe 18 and connecting shell 19, and then be thrown out through the throwing hopper 8, thereby improving the Fenton reaction effect of iron and carbon with sewage inside the device.

[0028] In a preferred embodiment, a controller is fixedly mounted on the outer wall of the tank 1, and the controller is electrically connected to the solenoid valve 15.

[0029] In the above structure, the controller structure allows the device to operate its various circuit components during operation and use, making it easier for users to operate and simplifying the operation process, thereby further improving the device's practicality.

[0030] In a preferred embodiment, the inner wall of the mounting groove 10 is slidably connected to the outer wall of the receiving hopper 13, and the outer wall of the receiving hopper 13 is slidably connected to the inner wall of the feeding hopper 3.

[0031] In the above structure, the installation groove 10 and the receiving hopper 13 are used to weigh iron and carbon, thereby achieving the effect of weighing iron and carbon, ensuring the accuracy of iron and carbon addition by the user, thus achieving the effect of treating sewage, and assisting the user in completing sewage treatment operations.

[0032] In a preferred embodiment, there are several stirring rods 7, and all of the stirring rods 7 are evenly distributed along the outer wall of the circular tube 6.

[0033] In the above structure, the multiple stirring rods 7 allow the device to stir the materials and wastewater during use, ensuring that the wastewater is in full contact with the materials, increasing the contact area between the materials and wastewater, and further improving the wastewater treatment effect of the device.

[0034] In a preferred embodiment, the outer wall of the receiving hopper 13 is provided with a through hole, and the inner wall of the through hole is slidably connected to the outer wall of the straight rod 11.

[0035] In the above structure, through the through hole and straight rod 11, after the user puts iron and carbon into the receiving hopper 13, the receiving hopper 13 will descend by the change in weight of the receiving hopper 13. The receiving hopper 13 can only rise and fall along the inner wall of the mounting groove 10, thereby avoiding the receiving hopper 13 from tilting or even shifting its position during the rising and falling process, thus improving the stability of the receiving hopper 13 during the rising and falling process.

[0036] In a preferred embodiment, the position of the extrusion rod 17 corresponds to the position of the pressure sensor 16, and the outer wall of the connecting shell 9 is provided with a discharge hole.

[0037] In the above structure, the pressure sensor 16 and the extrusion rod 17 are designed so that when the receiving hopper 13 descends, the pressure sensor 16 is compressed by the descending extrusion rod 17. This ensures that the device can complete the weighing of iron and carbon during operation, thereby achieving the effect of accurately adding iron and carbon and ensuring the normal use of the device.

[0038] In a preferred embodiment, the top end of the circular tube 6 is rotatably connected to the bottom of the connecting shell 9, and the connecting rod 19 is made of galvanized iron.

[0039] In the above structure, the rotating rod 5, the circular tube 6, and the connecting shell 9 enable the rotating rod 5 to drive the circular tube 6 to rotate during use, while the connecting shell 9 can receive the iron and carbon discharged from the receiving hopper 13, so that the iron and carbon can be discharged into the throwing hopper 8 to complete the throwing operation. The galvanized iron metal has the characteristic of hardness, which can ensure the tightness of the connection structure between the rotating rod 5 and the circular tube 6, thereby improving the stability of the device during operation.

[0040] like Figure 5As shown, the diameter of the connecting rod 19 is smaller than the bottom diameter of the connecting shell 9 and the diameter of the round tube 6, and the bottom of the connecting rod 19 is fixed to the inside of the round tube 6 through at least three connecting thin tubes. With this arrangement, the connecting rod 19 and the round tube 6 can be rotated synchronously during the rotation of the rotating rod 5. At the same time, the diameter of the connecting rod 19 is smaller than the bottom diameter of the connecting shell 9 and the diameter of the round tube 6, which facilitates the iron and carbon raw materials to enter the throwing hopper 8 along the round tube 6 and be thrown out through the throwing hopper 8. Among them, there are gaps between the at least three connecting thin tubes to facilitate the flow of iron and carbon raw materials.

[0041] The discharge pipe 4 is equipped with a valve to facilitate discharge work as needed.

[0042] Working principle: First, during operation, the user can put iron and carbon into the receiving hopper 13. At this time, with the solenoid valve 15 closed, the weight of the receiving hopper 13 increases, causing the receiving hopper 13 to descend and complete the weighing operation of the iron and carbon. Then, the user can open the solenoid valve 15 to discharge the iron and carbon into the connecting shell 9, which is then transported to the throwing hopper 8. This ensures the accuracy of the addition of iron and carbon, reduces material loss, and improves the practicality of the device. During operation, the motor 2 drives the rotating rod 5 and the round tube 6 to rotate together, causing the stirring rod 7 and the throwing hopper 8 to rotate together to stir the material. At the same time, the iron and carbon inside the throwing hopper 8 will be thrown out, increasing the contact area of ​​the material and thus improving the treatment effect of the device on sewage.
