Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment agent mixing device. Background Technology

[0002] In wastewater treatment, chemical mixing refers to the process of thoroughly mixing various wastewater treatment agents with the wastewater. This process is crucial to the effectiveness of wastewater treatment. Through chemical mixing, the agents can undergo physical or chemical reactions with pollutants in the wastewater, thereby achieving the purpose of pollutant treatment.

[0003] Existing equipment relies on simple stirring or natural mixing, which makes it difficult to achieve a highly uniform distribution of the reagent in the wastewater. This can easily lead to local over- or under-reaction, affecting the overall effectiveness and stability of wastewater treatment. For some recalcitrant pollutants, the chemical reaction rate between the reagent and the pollutant is relatively slow, resulting in longer treatment times and lower treatment efficiency.

[0004] To address these issues, those skilled in the art have proposed a wastewater treatment agent mixing device. Utility Model Content

[0013] As a preferred embodiment of the wastewater treatment agent mixing device of this utility model, a plurality of support columns are fixedly installed on the bottom outer wall of the mixing tank.

[0014] In a preferred embodiment of the wastewater treatment reagent mixing device of this utility model, the ultrasonic oscillation mechanism includes an ultrasonic transducer. An installation opening is located on the outer wall of the mixing tank near the bottom. The ultrasonic transducer is mounted on the inner wall of the installation opening. The ultrasonic oscillation mechanism also includes a mounting frame, which is fixed to the outer wall of the mixing tank near the installation opening. An ultrasonic generator is mounted on the inner wall of the mounting frame. One end of the ultrasonic generator is connected to a cable and an amplitude transformer. The ultrasonic generator is connected to the ultrasonic transducer via the cable and the amplitude transformer.

[0017] As a preferred embodiment of the wastewater treatment agent mixing device of this utility model, the stirring mechanism includes a motor, which is installed at the center of the surface of the mixing tank. The bottom end of the output shaft of the motor is fixedly connected to a transmission shaft. A sleeve is provided on the outer circumference of the transmission shaft near the bottom. Multiple stirring rods are provided on the outer circumference of the sleeve. The stirring rods are located between the ultrasonic transducer and the guide plate.

[0018] In a preferred embodiment of the wastewater treatment reagent mixing device of this utility model, the pH adjustment mechanism includes a pH adjustment tank, a connecting pipe is vertically installed at the top of the pH adjustment tank, the connecting pipe is inserted into the bottom inner wall of the mixing tank, a solenoid valve is provided inside the connecting pipe near the mixing tank, and an inlet pipe is provided on the outer wall of the pH adjustment tank near the top.

This avoids local over- or under-reaction and ensures the stability of the wastewater treatment effect. The dual effects of stirring and ultrasonic oscillation accelerate the contact and reaction between the agent and pollutants in the wastewater, shortening the treatment time. Compared with the traditional method of relying on simple stirring or natural mixing, this device can make the wastewater meet the treatment requirements in a shorter time, improving the overall treatment efficiency.

After the initial treatment, a higher frequency (100-500kHz) is used for oscillation, which is suitable for wastewater with high requirements for mixing uniformity and small pollutant particles, facilitating further wastewater treatment.

However, the present invention may also be implemented in other ways different from those described herein.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1

[0033] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a wastewater treatment agent mixing device that can achieve the dual effects of stirring and ultrasonic oscillation, thereby accelerating the contact and reaction between the agent and pollutants in the wastewater. It includes a mixing tank 100 for containing wastewater and agents.

[0034] A stirring mechanism 200 is installed inside the mixing tank 100 to stir and mix the wastewater and chemicals inside the mixing tank 100.

[0035] An ultrasonic oscillation mechanism 300 is provided. Multiple ultrasonic oscillation mechanisms 300 are symmetrically installed in the mixing box 100. The ultrasonic oscillation mechanism 300 includes two oscillation modes: low frequency and high frequency.

[0036] The pH adjustment mechanism 400 is connected to the mixing tank 100.

[0037] Specifically, a sewage pipe 101 is inserted into the top outer wall of the mixing tank 100, and a medicine inlet pipe 102 is inserted into the top outer wall of the mixing tank 100 near the sewage pipe 101.

[0038] Multiple support columns 103 are fixedly installed on the bottom outer wall of the mixing box 100.

[0039] In use, wastewater is poured into the mixing tank 100 through the wastewater pipe 101, and then the chemical is poured into the mixing tank 100 through the chemical inlet pipe 102. Then, the stirring mechanism 200 is activated to ensure that the chemical and wastewater are fully mixed. Then, the ultrasonic oscillation mechanism 300 is activated to generate cavitation, mechanical and thermal effects in the mixture, further refining the chemical particles and making the chemical more evenly dispersed in the wastewater. This avoids the phenomenon of excessive or insufficient local reaction and ensures the stability of the wastewater treatment effect. After the wastewater treatment is completed, the wastewater is sent into the pH adjustment mechanism 400 to adjust its pH value. Finally, the treated water is discharged.

[0040] Example 2

[0041] Reference Figure 1 , Figure 2 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the ultrasonic oscillation mechanism 300 includes an ultrasonic transducer 303. An installation port is opened on the outer wall of the mixing box 100 near the bottom. The ultrasonic transducer 303 is disposed on the inner wall of the installation port. The ultrasonic oscillation mechanism 300 also includes a mounting frame 301, which is fixed to the outer wall of the mixing box 100 near the installation port. An ultrasonic generator 302 is installed on the inner wall of the mounting frame 301. A cable and an amplitude transformer are installed at one end of the ultrasonic generator 302. The ultrasonic generator 302 is connected to the ultrasonic transducer 303 through the cable and the amplitude transformer.

[0042] Specifically, a sealing ring 304 is provided on the inner wall of the mixing box 100 near the outer edge of the mounting port, and the sealing ring 304 is attached to the outer wall of the ultrasonic transducer 303.

[0043] Furthermore, multiple guide plates 104 are installed in a ring on the bottom inner wall of the mixing tank 100. The longitudinal section of the guide plate 104 is trapezoidal, and the short side of the guide plate 104 is located near the center of the mixing tank 100.

[0044] The stirring mechanism 200 includes a motor 201, which is installed at the center of the surface of the mixing box 100. The bottom end of the output shaft of the motor 201 is fixedly connected to a transmission shaft 202. A sleeve is provided on the outer circumference of the transmission shaft 202 near the bottom. Multiple stirring rods 203 are provided on the outer circumference of the sleeve. The stirring rods 203 are located between the ultrasonic transducer 303 and the guide plate 104.

[0045] During operation, motor 201 drives the transmission shaft 202 and stirring rod 203 to rotate, agitating the wastewater and chemicals in the mixing tank 100 to achieve initial mixing. The ultrasonic generator 302 generates a high-frequency electrical signal, which is converted into mechanical vibration by the ultrasonic transducer 303. This generates cavitation, mechanical, and thermal effects in the mixed liquid, making the chemicals more evenly dispersed in the wastewater. The guide plate 104 guides the liquid to flow towards the center, causing the liquid to circulate under the action of ultrasonic waves, further improving the mixing uniformity. The ultrasonic oscillation mechanism 300 first uses a lower frequency (20-40kHz) of ultrasonic waves for oscillation, which has a strong cavitation effect and is suitable for treating wastewater containing large particulate pollutants or requiring strong crushing and mixing for initial wastewater treatment. After the initial treatment, a higher frequency (100-500kHz) is used for oscillation, which is suitable for wastewater with high requirements for mixing uniformity and small pollutant particles, facilitating further wastewater treatment.

A solenoid valve 403 is provided inside the connecting pipe 402 near the mixing box 100. An inlet pipe 404 is provided on the outer wall of the pH adjustment box 401 near the top.

[0048] Specifically, a pH meter 405 is inserted into the outer wall of the pH adjustment box 401, one end of which extends into the interior of the pH adjustment box 401, and a discharge pipe 407 is inserted into the outer wall of the pH adjustment box 401 near the bottom.

[0049] Furthermore, a second motor 406 is installed at the center of the bottom outer wall of the pH regulating box 401. A connecting shaft is installed at the top of the output shaft of the second motor 406. The connecting shaft is vertically located inside the pH regulating box 401, and multiple connecting rods are installed on the outer circumference of the connecting shaft.

[0050] When in use, after the wastewater and the agent inside the mixing tank 100 have been mixed and treated, open the solenoid valve 403 so that the mixture enters the pH adjustment tank 401 through the connecting pipe 402. The pH value of the mixture is detected by the pH meter 405. Then, the neutralizing liquid is poured in through the inlet pipe 404 to adjust the pH value of the mixture. Start the motor 406 to drive the connecting rod to rotate and mix the mixture evenly. After the pH value of the mixture is adjusted, the mixture is discharged through the outlet pipe 407.
