Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a wastewater purification device. Background Technology

[0002] Acidic wastewater is a significant environmental pollution problem originating from industrial production and human activities. Sulfides in ores oxidize during mining to produce sulfuric acid, forming acidic mine drainage; electroplating and pickling processes in the metal processing industry generate wastewater containing acidic substances; the chemical and pharmaceutical industries use large quantities of acidic raw materials, and improper treatment can lead to the discharge of acidic wastewater; the combustion of fossil fuels produces acidic gases, which, through atmospheric deposition, form acidic rainwater; and fertilizers and pesticides used in agricultural production can lead to acidic agricultural drainage. In short, potential sources of acidic wastewater exist in all sectors of human society. Acidic wastewater is highly corrosive, eroding pipes, equipment, buildings, and other infrastructure. It contains toxic and harmful components such as heavy metals and acidic substances. If it seeps into groundwater or is directly discharged into drinking water sources, it will severely pollute water sources and threaten human health. Therefore, the treatment of acidic wastewater is essential.

[0003] In existing acidic wastewater treatment processes, sodium hydroxide (NaOH) is used as a neutralizing agent, mixed with acidic wastewater to adjust its pH to neutral or near-neutral levels, thereby effectively reducing the potential environmental hazards of the wastewater. However, in practice, the amount of sodium hydroxide added often relies on the experience and judgment of on-site personnel. This method of operation, which depends on human experience, has many shortcomings. First, factors such as human emotions, fatigue, and distraction can affect the judgment of personnel, making it difficult to accurately control the concentration of sodium hydroxide during actual operation. Sometimes, too little sodium hydroxide may be added, resulting in insufficient neutralization of the wastewater's pH and poor purification effect, leaving it still containing substances harmful to the environment. At other times, too much sodium hydroxide may be added, making the wastewater too alkaline, wasting sodium hydroxide resources and potentially introducing new environmental problems, such as soil alkalization and the death of aquatic organisms. Second, the lack of precise control in the addition of sodium hydroxide can also lead to unstable wastewater treatment costs. Excessive consumption of sodium hydroxide increases operating costs, while poor treatment results may require more subsequent treatment steps, further increasing the overall cost.

[0004] To address the problems mentioned in the background section, this utility model provides a wastewater purification device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater purification device, comprising a purification tank, a vertical plate fixedly installed on the top of the purification tank, an outer cylinder fixedly installed on the top of the vertical plate, and an inner cylinder movably installed inside the outer cylinder, a feed pipe fixedly installed on the top of the outer cylinder, a discharge pipe fixedly installed on the bottom of the outer cylinder, a feed pipe fixedly installed on the top of the inner cylinder, a discharge pipe fixedly installed on the bottom of the inner cylinder, a drive motor fixedly installed on the top of the outer cylinder, and the output shaft of the drive motor fixedly connected to the inner cylinder, a conveying pipe fixedly installed on one end of the discharge pipe, and a discharge pipe fixedly installed on the bottom of the conveying pipe extending into the interior of the purification tank, a round rod movably installed inside the conveying pipe, and a spiral blade fixedly installed on the surface of the round rod, and a drive motor fixedly installed on one end of the conveying pipe, and the output shaft of the drive motor fixedly connected to the round rod.

[0008] Preferably, the bottom of the outer cylinder is provided with an annular groove, and the bottom of the inner cylinder is fixedly installed with an annular plate, which is located inside the annular groove.

[0009] Preferably, three sets of support legs are fixedly installed at the bottom of the purification box, and support leg pads are fixedly installed at the bottom of each of the three sets of support legs.

[0010] Preferably, an observation window is fixedly installed on the surface of the purification box, and the observation window is made of glass. A reinforcing rib is provided at the connection between the purification box and the vertical plate, and the reinforcing rib is triangular in shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses the power of a drive motor to rotate the inner cylinder. When the discharge pipe 2 coincides with the discharge pipe 1, the particles fall from the inside of the discharge pipe 1 into the inside of the conveying pipe. Subsequently, the power of the drive motor 2 causes the spiral blades on the surface of the round rod to rotate, which drives the particles to move continuously in the gap between the spiral blades. When passing above the discharge pipe, they fall into the purification tank. Compared with traditional devices, this device can ensure that sodium hydroxide and pollutants in wastewater have sufficient contact and reaction, thereby helping to accelerate the reaction rate and improve the treatment efficiency. It can also avoid the problem of poor treatment effect caused by excessively high or low local concentrations. At the same time, it can achieve effective purification treatment of acidic wastewater. It not only has the advantages of acid-base neutralization and adjustment, precipitation of heavy metal ions, and improved treatment efficiency, but is also easy to operate and control and has high cost-effectiveness.

[0013] 2. This utility model uses the power of a drive motor to rotate the stirring blades on the surface of the movable rod, thereby mixing wastewater and particulate matter. Simultaneously, the rotation of the rotating rod further mixes the fan-shaped blades. Compared with traditional devices, this device significantly reduces corrosion, thus extending the service life of equipment and pipelines, reducing maintenance and replacement costs, and protecting the ecological environment. Neutral or near-neutral wastewater has less environmental impact, contributing to ecological balance and biodiversity. Furthermore, adjusting the wastewater to neutral or near-neutral pH optimizes subsequent treatment processes and improves overall treatment efficiency. Attached Figure Description

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.

[0021] like Figures 1 to 5 As shown, this utility model provides a wastewater purification device, including a purification tank 1. A vertical plate 2 is fixedly installed on the top of the purification tank 1. An outer cylinder 3 is fixedly installed on the top of the vertical plate 2, and an inner cylinder 6 is movably installed inside the outer cylinder 3. A feed pipe 4 is fixedly installed on the top of the outer cylinder 3, and a discharge pipe 5 is fixedly installed on the bottom of the outer cylinder 3.

It not only has the advantages of acid-base neutralization and adjustment, precipitation of heavy metal ions, and improved treatment efficiency, but is also easy to operate and control and has high cost-effectiveness.

[0023] like Figure 5As shown, the purification box 1 is fixedly installed with an inlet pipe 15 and an outlet pipe 16 in sequence. The purification box 1 is movably installed with a movable rod 17 inside. The surface of the movable rod 17 is fixedly installed with a stirring plate 19.

The bottom of the purification box 1 is fixedly installed with a drive motor 18, and the output shaft of the drive motor 18 is fixedly connected to the movable rod 17.

[0024] The above solution significantly reduces corrosion, thereby extending the service life of equipment and pipelines, reducing maintenance and replacement costs, and protecting the ecological environment. Neutral or near-neutral wastewater has less environmental impact, which is beneficial to protecting ecological balance and biodiversity. Furthermore, adjusting the wastewater to neutral or near-neutral pH can optimize the effectiveness of subsequent treatment processes and improve overall treatment efficiency.

[0025] like Figure 2 As shown, a motor protective cover 22 is provided at the bottom of the purification box 1, and the drive motor 3 18 is located inside the motor protective cover 22. Heat dissipation holes 23 are provided on the surface of the motor protective cover 22.

[0026] The above solution is adopted: by setting a motor protection cover 22 at the bottom of the purification box 1, and the drive motor 3 18 is located inside the motor protection cover 22, the safety of the drive motor 3 18 is better protected. Heat dissipation holes 23 are opened on the surface of the motor protection cover 22 to improve the heat dissipation of the drive motor 3 18.

[0027] like Figure 3 As shown, an annular groove 24 is provided at the bottom of the inner cylinder 3, and an annular plate 25 is fixedly installed at the bottom of the inner cylinder 6, with the annular plate 25 located inside the annular groove 24.

[0028] The above solution is adopted: by opening a circular groove 24 at the bottom of the inner cylinder 3, and fixing a circular plate 25 at the bottom of the inner cylinder 6, and the circular plate 25 is located inside the circular groove 24, the stability of the inner cylinder 6 is higher when it rotates inside the outer cylinder 3.

[0029] like Figure 1 As shown, three sets of support legs 28 are fixedly installed at the bottom of the purification box 1, and support leg pads 29 are fixedly installed at the bottom of each of the three sets of support legs 28.

Support leg pads 29 are fixedly installed at the bottom of each of the three sets of support legs 28, which can contact the area between the support legs and the ground, further improving the stability.

[0031] like Figure 1As shown, an observation window 27 is fixedly installed on the surface of the purification box 1, and the observation window 27 is made of glass. A reinforcing rib 26 is provided at the connection between the purification box 1 and the vertical plate 2, and the reinforcing rib 26 is triangular in shape.

[0032] The above solution is adopted: by fixing an observation window 27 on the surface of the purification box 1, and the observation window 27 is made of glass, the staff can observe the internal condition of the purification box 1 more clearly. A reinforcing rib 26 is provided at the connection between the purification box 1 and the vertical plate 2, and the reinforcing rib 26 is triangular in shape, and the triangle has stability.

[0033] Working principle and usage process of this utility model:

[0034] Before use, the staff inserts sodium hydroxide granules from above the feed pipe 4 and into the inner cylinder 6 through the feed pipe 7. During use, the staff starts the drive motor 9 through an external switch. The power generated by the drive motor 9 causes the inner cylinder 6 to rotate. The rotation of the inner cylinder 6 causes the discharge pipe 8 to overlap with the discharge pipe 5. Then, the shell falls into the conveying pipe 10 through the discharge pipe 5. Then, the staff starts the drive motor 14. The force generated by the drive motor 14 causes the round rod 12 to rotate. The rotation of the round rod 12 causes the granules that fall into the gap between the spiral blades 13 to move continuously to the top of the discharge pipe 11 and fall into the purification box 1 through the discharge pipe 11.

[0035] In use, wastewater is injected into the purification tank 1 after connecting the inlet pipe 15. The particulate matter and wastewater are then mixed. The operator then starts the drive motor 18. The power generated by the drive motor 18 causes the movable rod 17 to rotate. The stirring plate 19 on the surface of the movable rod 17 mixes the wastewater and particulate matter. At the same time, the rotation of the stirring plate 19 causes the rotating rod 20 to rotate, which in turn causes the fan-shaped plate 21 to rotate, further mixing the wastewater and particulate matter.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
