DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: an oil-containing wastewater high-COD reduction device, including a treatment tank 1, a motor 2, a main stirring rod 3, a feeding pipe 4, an end cover 5, a transmission ring 6, a secondary stirring rod 7, an exhaust pipe 8, a transmission rod 9, a fan blade 10, an activated carbon cotton 11, a limiting mechanism 12, a positioning rod 1201, a bushing 1202, a clamping frame 1203, a spring 1204, an upper sprocket mechanism 13 and a lower sprocket mechanism 14. A motor 2 is fixedly arranged in the middle of the upper surface of the treatment tank 1, and the lower end of the output shaft of the motor 2 is fixedly connected to the main stirring rod 3. A feeding pipe 4 penetrates through the upper surface of the treatment tank 1 on the side of the motor 2. The outer walls of the upper and lower ends of the feeding pipe 4 are respectively sleeved with an end cover 5 and a transmission ring 6. At the same time, the outer wall of the side of the lower end of the transmission ring 6 is fixedly connected to a secondary stirring rod 7. An exhaust pipe 8 is installed through the side of the feeding pipe 4. The inner wall of the treatment tank 1 on the side of the feeding pipe 4 is movably connected to a transmission rod 9. The upper outer wall of the transmission rod 9 inside the exhaust pipe 8 is fixedly connected to a fan blade 10. The upper inner wall of the exhaust pipe 8 is movably connected to an activated carbon cotton 11. At the same time, a limiting mechanism 12 is installed on the outer wall of the upper end of the side of the exhaust pipe 8.

[0022] The feeding pipe 4 and the end cover 5 are threadedly connected, and the feeding pipe 4 and the transmission ring 6 form a rotating structure, which is convenient for the user to rotate the end cover 5 for disassembly and assembly of the end cover 5, and is convenient for the transmission ring 6 to rotate relative to the feeding pipe 4.

[0023] The upper outer wall of the transmission ring 6 is connected to the upper outer wall of the main stirring rod 3 through the upper sprocket mechanism 13. The outer wall of the transmission ring 6 below the upper sprocket mechanism 13 is connected to the lower outer wall of the transmission rod 9 through the lower sprocket mechanism 14. The transmission rod 9 is rotatably arranged with the treatment tank 1 and the exhaust pipe 8 respectively. When the motor 2 drives the main stirring rod 3 to rotate, the main stirring rod 3 drives the upper sprocket mechanism 13 to make the transmission ring 6 rotate, so that the transmission ring 6 drives the secondary stirring rod 7 to rotate to improve the stirring ability of the device. At the same time, the transmission ring 6 drives the lower sprocket mechanism 14 to make the transmission rod 9 rotate.

[0024] The limiting mechanism 12 includes a positioning rod 1201, a ferrule 1202, a clamping frame 1203 and a spring 1204. The positioning rod 1201 is fixedly installed on the upper outer wall of the side of the exhaust pipe 8, and a ferrule 1202 is sleeved on the outer wall of the positioning rod 1201. Moreover, a clamping frame 1203 is fixedly arranged on the upper surface of the ferrule 1202, which is convenient for limiting the activated carbon cotton 11 through the limiting mechanism 12 and ensuring the stability of the activated carbon cotton 11 during use.

[0025] The positioning rod 1201 and the ferrule 1202 form a sliding structure, and the end face of the ferrule 1202 is connected to the outer wall of the end of the positioning rod 1201 through the spring 1204, which is convenient for elastically supporting the ferrule 1202 through the spring 1204 and for the ferrule 1202 to slide relative to the positioning rod 1201.

[0026] The ferrule 1202 is in contact with the exhaust pipe 8, and both the clamping frame 1203 and the activated carbon cotton 11 are slidably arranged on the exhaust pipe 8. It is convenient for the spring 1204 to support the ferrule 1202 so that the ferrule 1202 is in contact with the exhaust pipe 8, thereby enabling the clamping frame 1203 to stably limit the activated carbon cotton 11, and for the clamping frame 1203 to move away from the activated carbon cotton 11, thus facilitating the user to draw out the activated carbon cotton 11 in the exhaust pipe 8 for replacement.

[0027] Working principle: When using this high-COD reduction device for oily wastewater, first as Figures 1-3 shown, the user pulls the clamping frame 1203 to make the clamping frame 1203 move away from the exhaust pipe 8. Then the clamping frame 1203 drives the ferrule 1202 to slide relative to the positioning rod 1201. And as the ferrule 1202 moves, the ferrule 1202 compresses the spring 1204 to deform. Next, the user inserts the activated carbon cotton 11 into the exhaust pipe 8. Subsequently, the user releases the clamping frame 1203. At this time, the spring 1204 resets and pushes the ferrule 1202 so that the clamping frame 1203 moves above the activated carbon cotton 11, thereby limiting the activated carbon cotton 11 to complete the installation of the activated carbon cotton 11. Then as Figures 1-4 shown, the user adds the oily wastewater with high COD and the treatment reagent to the treatment tank 1 through the feeding pipe 4. Then the user covers the end cover 5 on the feeding pipe 4 and tightens the end cover 5. Next, the user starts the motor 2. Subsequently, the motor 2 drives the main stirring rod 3 to mix the materials for wastewater treatment. At the same time, the main stirring rod 3 drives the transmission ring 6 to rotate through the upper sprocket mechanism 13. Then the transmission ring 6 drives the transmission rod 9 to rotate through the lower sprocket mechanism 14. At this time, the main stirring rod 3, the auxiliary stirring rod 7 and the fan blades 10 rotate simultaneously, thereby improving the stirring ability of the device, facilitating the full mixing of the materials to ensure the wastewater treatment effect. Then the fan blades 10 blow the air to flow so that the waste gas generated in the device is discharged from the device through the feeding pipe 4 and the exhaust pipe 8. At this time, the activated carbon cotton 11 purifies the waste gas. Therefore, the device is convenient for treating the processing waste gas, thus avoiding the direct emission of waste gas to pollute the atmospheric environment.

[0028] Although the present utility model 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 perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
