[0002] Wastewater discharged from chemical production processes, such as process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site rinsing water, can change their original physical or chemical properties after use, becoming wastewater containing different kinds of impurities.

[0003] Chemical wastewater includes process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site washing water discharged during chemical production. If this wastewater is discharged without treatment, it will cause pollution of water bodies of different properties and degrees, thereby endangering human health and affecting industrial and agricultural production. If the wastewater can be aerated, sufficient oxygen can be provided for aerobic microorganisms in the wastewater, promoting their growth and metabolism, accelerating the degradation of organic matter, and thus enabling it to be discharged or reused smoothly. Therefore, we propose a chemical wastewater treatment device with an aeration structure. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a chemical wastewater treatment device with an aeration structure includes a treatment cylinder 1. An inlet 4 is provided on the surface of the treatment cylinder 1. An aerator 10 is fixedly connected to the inner wall of the treatment cylinder 1. The inlet 4 is located above the aerator 10. A heater 12 is fixedly connected to the bottom of the treatment cylinder 1. A controller 13 is fixedly connected to the front of the heater 12. A connecting wire 20 is fixedly connected to the surface of the heater 12. A heating wire 14 is fixedly connected to the end of the connecting wire 20 away from the heater 12. The heating wire 14 is located on the inner wall of the treatment cylinder 1 and flows through the inlet 4. Add the chemical wastewater to be treated. The wastewater will then pass through the aerator 10 installed inside the treatment cylinder 1. Since a variable frequency fan is installed inside the aerator 10, the oxygen utilization rate inside the treatment cylinder 1 can be effectively improved, and energy consumption can be reduced. Then, the motor 2 located above the treatment cylinder 1 and the heater 12 at the bottom of the treatment cylinder 1 are started simultaneously. The heater 12 will heat the heating wire 14 installed on the inner wall of the treatment cylinder 1 through the connecting wire 20, thereby increasing the temperature inside the treatment cylinder 1, thereby accelerating the chemical reaction and enhancing the biodegradation effect.

[0022] The inner wall of the treatment cylinder 1 is fixedly connected to a fixed box 22, and the inner wall of the fixed box 22 is fixedly connected to a temperature sensor 9. The temperature sensor 9 is electrically connected to the controller 13. A ventilation window 3 is opened on the surface of the treatment cylinder 1. When the temperature sensor 9 detects that the stability inside the treatment cylinder 1 reaches the limit required for chemical wastewater treatment, it will feed back to the controller 13, thereby stopping the heater 12 from working, which is very convenient.

[0023] A motor 2 is fixedly connected to the top of the treatment cylinder 1. A stirring rod 8 is fixedly connected to one end of the motor 2 near the treatment cylinder 1. The stirring rod 8 passes through the treatment cylinder 1 and extends into its interior. A stirring blade 11 is fixedly connected to the surface of the stirring rod 8. When the motor 2 is started, it drives the stirring rod 8 at the output end to rotate. As a result of the rotation of the stirring rod 8, it synchronously drives the stirring blade 11 on the surface to rotate as well, thereby accelerating the reaction and treatment of the chemical wastewater inside the treatment cylinder 1.

[0024] The number of stirring blades 11 is set to several, and the several stirring blades 11 are fixedly connected to the surface of the stirring rod 8. The stirring blades 11 are located below the aerator 10, and the aerator 10 is located below the ventilation window 3.

[0025] A rotary valve 21 is rotatably connected to the surface of the processing cylinder 1. A connecting rod 15 is fixedly connected inside the rotary valve 21. A docking plate 16 is fixedly connected to the end of the connecting rod 15 away from the rotary valve 21. A fixing rod 17 is fixedly connected to the end of the docking plate 16 away from the connecting rod 15.

[0026] The processing cylinder 1 has a sliding groove 19 at the bottom of its inner wall, and a through groove on the surface of the sliding groove 19. A slide plate 18 is slidably connected to the top of the through groove. The slide plate 18 is slidably connected to the inner wall of the sliding groove 19, and a fixing rod 17 is fixedly connected to the top of the slide plate 18.

[0027] The bottom of the treatment cylinder 1 is fixedly connected to a conveying pipe 5. The end of the conveying pipe 5 away from the treatment cylinder 1 is fixedly connected to a storage tank 6. The conveying pipe 5 is located below the passage channel. The bottom of the treatment cylinder 1 is fixedly connected to a supporting leg 7. The number of supporting legs 7 is set to several. All supporting legs 7 are fixedly connected to the bottom of the treatment cylinder 1. By rotating the rotary valve 21, the connecting rod 15 can be rotated. As a result, the rotation of the connecting rod 15 will cause the docking plate 16 and its front fixed rod 17 to slide inside the sliding channel 19. This causes the sliding plate 18 to slide on the inner wall of the sliding channel 19 at the same time, so that the chemical wastewater can enter the storage tank 6 from the conveying pipe 5 below the passage channel and be discharged.

[0028] This utility model provides a chemical wastewater treatment device with an aeration structure, the specific working principle of which is as follows:

[0029] During use, the user needs to add the chemical wastewater to be treated through the inlet 4. The wastewater will then pass through the aerator 10 installed inside the treatment cylinder 1. Since a variable frequency fan is installed inside the aerator 10, the oxygen utilization rate inside the treatment cylinder 1 can be effectively improved, while reducing energy consumption. Subsequently, the motor 2 located above the treatment cylinder 1 and the heater 12 at the bottom of the treatment cylinder 1 are simultaneously activated. The heater 12, through the connecting wire 20, heats the heating wire 14 installed on the inner wall of the treatment cylinder 1, thereby increasing the temperature inside the treatment cylinder 1, accelerating the chemical reaction, and enhancing the biodegradation effect. Meanwhile, the chemical wastewater to be treated can be added through the inlet 4. A certain amount of treatment liquid is processed, and the motor 2 is started. The motor 2 will drive the stirring rod 8 at the output end to rotate. As a result, the rotation of the stirring rod 8 will drive the stirring fan blades 11 on the surface to rotate simultaneously, thereby accelerating the reaction treatment of the chemical wastewater inside the treatment cylinder 1. Finally, turning the rotary valve 21 will drive the connecting rod 15 to rotate. As a result, the rotation of the connecting rod 15 will drive the docking plate 16 and its front fixed rod 17 to slide inside the sliding groove 19, thereby causing the sliding plate 18 to slide on the inner wall of the sliding groove 19. This allows the chemical wastewater to enter the storage tank 6 through the conveying pipe 5 below the groove, and then be discharged.
