Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a pH control device for treating beverage wastewater. Background Technology

[0002] As is well known, beverage wastewater treatment is a crucial aspect of environmental protection. Its goal is to remove pollutants from wastewater through a series of physical, chemical, and biological methods to meet discharge standards or facilitate reuse. Among the many treatment steps, adjusting the wastewater's pH value is critical, as many subsequent treatment processes (such as coagulation sedimentation and biological treatment) have strict requirements regarding the wastewater's acidity or alkalinity. Traditional pH control methods often have the following limitations.

[0003] Traditional mixing devices can only achieve simple circular motion, which leads to insufficient mixing between the regulator and wastewater, easily causing local concentrations to be too high or too low, affecting the final treatment effect. Manually adding regulators makes it difficult to accurately control the amount added, which may not only lead to chemical waste, but also introduce new pollution problems due to excessive use of regulators. In addition, the error caused by manual operation is large, and it is difficult to guarantee the consistency and reliability of the treatment results. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a pH control device for beverage wastewater treatment, which has the following beneficial effects:

[0016] The pH control device for beverage wastewater treatment features a stirring mechanism. The stirring blades revolve around a central axis while also rotating on their own axis, ensuring that the stirring is not limited to simple circular motion. Furthermore, the inclined design of the stirring blades promotes the vertical circulation of wastewater within the treatment tank. This facilitates rapid and uniform mixing of the regulator and wastewater, preventing issues such as excessively high or low concentrations in certain areas. The efficient operation of the stirring device ensures that all components are fully mixed.

[0017] This pH control device for beverage wastewater treatment utilizes a solid-state pH sensor, a control system, an acidity adjustment device, and an alkalinity adjustment device.

[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 1-4A pH control device for treating beverage wastewater includes a treatment tank 1, a stirring device, an acidity adjustment device, and an alkalinity adjustment device. A solid-state pH sensor 2 is installed on the inner wall of the treatment tank 1. A control system 3 is installed on the front side wall of the treatment tank 1. The acidity adjustment device is installed at one end of the treatment tank 1, and the alkalinity adjustment device is installed at the other end. The stirring device is installed inside the treatment tank 1. The stirring device includes a drive motor 4, a rotating shaft 5, a connecting plate 6, a gear ring 7, a gear 8, a stirring shaft 9, and stirring blades 10. A protective shell 11 is installed on the top wall of the treatment tank 1, and the drive motor 4 is installed at the top of the protective shell 11. The bottom output end of 4 is connected to the rotating shaft 5 through the protective shell 11. The connecting plate 6 is fixedly installed on the side wall of the rotating shaft 5. The gear ring 7 is installed on the inner wall of the protective shell 11. The gear 8 is meshed in the gear ring 7. The stirring shaft 9 is installed in the middle of the gear 8. The top end of the connecting plate 6 is rotatably connected to the top end of the stirring shaft 9. Multiple sets of stirring blades 10 are installed on the side wall of the stirring shaft 9. In this embodiment, when in use, firstly, the beverage wastewater to be treated is introduced into the treatment tank 1. At this time, the solid pH sensor 2 installed on the inner side wall of the treatment tank 1 begins to monitor the pH value of the wastewater in real time and feeds the data back to the control system 3 on the front side wall. According to the pH information received by the control system 3, if the wastewater is detected to be acidic, an appropriate amount of alkaline regulator (such as sodium hydroxide solution) is added through the acidity adjustment device; conversely, if the wastewater is alkaline, an acidic regulator (such as sulfuric acid or hydrochloric acid) is added through the alkalinity adjustment device. The added regulator is evenly dispersed in the wastewater by a stirring device. When the acidic or alkaline regulator is placed in the treatment tank 1, the operator or the automatic control system 3 starts the drive motor 4. The output end of the first motor drives the rotating shaft 5 to rotate. Since the connecting plate 6 is fixedly connected to the rotating shaft 5, and the gear 8 meshes with the gear ring 7, the connecting plate 6 drives the gear 8 to rotate along the inner side of the gear ring 7, and in the rotational action of the connecting plate 6... The stirring shaft 9 and stirring blade 10 rotate around the rotating shaft 5 while also rotating on their own axis. The rotation of the stirring shaft and stirring blade 10 promotes the circulation of wastewater in the treatment tank 1, prevents the conditioner from settling, and ensures that the liquid in the entire container is uniformly stirred, achieving efficient mixing of the conditioner and wastewater. Throughout the treatment process, the solid pH sensor 2 continuously monitors the pH value changes of the wastewater. The control system 3 dynamically adjusts the amount of acid-base conditioner added based on real-time data until the preset target pH range is reached. When the pH value of the wastewater stabilizes within the target range, the control system 3 stops adding conditioner and shuts off the drive motor 4, completing the entire treatment process.

[0025] Preferably, in this embodiment, the acidity adjustment device includes a first inlet pipe 12, an acidic storage tank 13, and a first metering pump 14. The first inlet pipe 12 is installed on the upper side wall of one end of the treatment tank 1, and the acidic storage tank 13 is installed at the top of the first inlet pipe 12. The first metering pump 14 is installed on the outer wall of the first inlet pipe 12. When the solid pH sensor 2 detects that the pH value of the wastewater in the treatment tank 1 is too high (i.e., the wastewater is alkaline), the sensor transmits the data to the control system 3 for analysis. Once it is determined that an acidic regulator needs to be added to lower the pH value, the control system 3 will activate the first metering pump 14. This metering pump is installed on the outer wall of the first inlet pipe 12 and is directly connected to the acidic storage tank 13 and the treatment tank 1. 4. According to the instructions of the control system 3, an appropriate amount of acidic regulator (such as sulfuric acid or hydrochloric acid) is drawn from the acidic storage tank 13 and accurately injected into the treatment tank 1 through the first inlet pipe 12. The metering pump can ensure that the chemical dosage added each time is accurate and avoids over- or under-dosage. At the same time, the stirring device starts to work, and the drive motor 4 drives the rotating shaft 5 to rotate, so that the stirring blades 10 can fully stir the wastewater, ensuring that the acidic regulator can be quickly and evenly dispersed in the entire water body, achieving the effect of quickly adjusting the pH value. The pH sensor continues to monitor the pH change of the wastewater in real time and feeds the information back to the control system 3. If the pH value still does not reach the preset range, the system will continue to fine-tune the operating parameters of the first metering pump 14 until the pH value stabilizes within the target range.

[0026] Preferably, in this embodiment, the alkalinity adjustment device includes a second inlet pipe 15, an alkaline storage tank 16, and a second metering pump 17. The second inlet pipe 15 is installed on the upper side wall of the other end of the treatment tank 1, and the alkaline storage tank 16 is installed at the top of the second inlet pipe 15. The second metering pump 17 is installed on the outer wall of the second inlet pipe 15. When the solid pH sensor 2 detects that the pH value of the wastewater in the treatment tank 1 is too low (i.e., the wastewater is acidic), the sensor transmits the data to the control system 3 for analysis. Once it is determined that an alkaline regulator needs to be added to increase the pH value, the control system 3 will activate the second metering pump 17. This metering pump is installed on the outer wall of the second inlet pipe 15 and is directly connected to the alkaline storage tank 16 and the treatment tank 1. According to the instructions of the control system 3, an appropriate amount of alkaline regulator (such as sodium hydroxide or sodium carbonate) is drawn from the alkaline storage tank 16 and accurately injected into the treatment tank 1 through the second inlet pipe 15. The metering pump can ensure that the chemical dosage added each time is accurate and avoids over- or under-dosage. At the same time, the stirring device starts to work, and the drive motor 4 drives the rotating shaft 5 to rotate, so that the stirring blades 10 can fully stir the wastewater, ensuring that the alkaline regulator can be quickly and evenly dispersed in the entire water body, achieving the effect of rapid pH adjustment. The pH sensor continues to monitor the pH change of the wastewater in real time and feeds the information back to the control system 3. If the pH value still does not reach the preset range, the system will continue to fine-tune the operating parameters of the second metering pump 17 until the pH value stabilizes within the target range.

[0027] Preferably, in this embodiment, the stirring blade 10 is installed at an angle on the side wall of the stirring shaft 9. The angled stirring blade 10 can generate stronger shear force, which helps to break up agglomerates or suspended particles in the liquid, making it easier to mix materials of different densities and viscosities evenly. The angled blade can not only push the liquid to make circular motion, but also make the liquid flow in the axial direction. This three-dimensional flow mode can more effectively prevent solid sedimentation and ensure that the materials in the entire processing tank 1 are fully stirred.

[0028] Preferably, in this embodiment, the tilt angle of the stirring blade 10 is between 30 degrees and 60 degrees. Within this angle range, the stirring blade 10 can effectively generate sufficient shear force, which is very effective for dispersing particulate matter in liquid or dissolving solids. An appropriate angle helps to break up agglomerated particles and promotes the uniform distribution of finer particles throughout the solution.

[0029] Preferably, in this embodiment, the drive motor 4 is a servo motor. A servo motor can achieve very precise position control, which is crucial for applications requiring accurate adjustment of stirring speed and position. For example, in beverage wastewater treatment, when adjusting the stirring intensity based on real-time monitored pH changes, a servo motor can provide the necessary fine control.

[0030] Preferably, in this embodiment, both the top of the acidic storage tank 13 and the top of the alkaline storage tank 16 are equipped with feed pipes 18. Top feeding makes it simple and easy to add new chemicals to the storage tanks without moving the storage tanks or using additional equipment, thus improving work efficiency.

The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.
