Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a multi-stage oxidation device suitable for industrial wastewater treatment. Background Technology

[0002] When treating industrial wastewater, a multi-stage oxidation device is often used. By oxidizing the wastewater step by step and in stages, it can significantly improve the removal efficiency of organic matter, reduce the content of harmful substances in the wastewater, reduce the risk of secondary pollution, and improve the water quality to discharge standards or higher, thus meeting environmental protection requirements. This device usually combines multiple oxidation technologies, such as chemical oxidation and photocatalytic oxidation, to achieve more thorough decomposition of pollutants. This device is used because it can provide flexible and efficient treatment solutions for complex and varied industrial wastewater compositions, ensuring that the wastewater meets strict environmental standards before discharge, protecting the ecological environment and human health.

[0003] Multi-stage oxidation devices suitable for industrial wastewater treatment oxidize wastewater step by step through multiple stages: First, the wastewater enters the primary oxidation zone, where some organic matter begins to be oxidized and decomposed under the action of specific catalysts and oxygen; then it enters the intermediate oxidation zone, where organic pollutants in the wastewater are further removed under stronger oxidation conditions such as higher temperature, pressure, and the synergistic effect of different catalysts; finally, it reaches the advanced oxidation zone, where strong oxidants such as ozone and persulfate are used to deeply oxidize the remaining recalcitrant organic matter, transforming it into harmless small molecules or even completely mineralizing it, ultimately achieving efficient purification of the wastewater so that it meets discharge standards or reuse standards.

[0004] Existing technologies include multi-stage oxidation devices suitable for industrial wastewater treatment. However, current technologies for industrial wastewater treatment have many problems that urgently need to be solved. While some existing wastewater treatment devices can treat some industrial wastewater to a certain extent, they are significantly inadequate in terms of filtration. Many traditional devices can only treat some pollutants in wastewater, and it is difficult to achieve efficient filtration and separation of some fine particles, colloidal substances, and dissolved pollutants. This results in the treated wastewater still containing a large amount of harmful substances, failing to meet increasingly stringent environmental emission standards. Therefore, a multi-stage oxidation device suitable for industrial wastewater treatment is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 2 The present invention provides an embodiment of a multi-stage oxidation device suitable for industrial wastewater treatment, comprising a treatment tank shell 1, which provides a closed reaction space for industrial wastewater treatment, preventing wastewater leakage during treatment and avoiding pollution to the surrounding environment. Water inlets 2 are fixedly connected to one side of the space area at the top of the treatment tank shell 1 to ensure that industrial wastewater can enter the treatment tank evenly and avoid excessive or insufficient local flow, which would affect the treatment effect.

[0033] A motor housing 3 is fixedly connected to the top space of the treatment tank shell 1. This motor housing is used to install and fix the drive components for industrial wastewater treatment and purification. The interior is equipped with partitions and brackets to separate different components, avoid mutual interference, and facilitate maintenance and repair. The drive components for industrial wastewater treatment and purification are fixedly connected to the interior space of the motor housing 3. When the motor 4 is powered on, it starts to rotate and outputs power. The power is transmitted to the rotating shaft 5 through the transmission mechanism, which drives the stirring rod 6 and the scraper 7 to rotate inside the treatment tank.

[0034] The rotation of the stirring rod 6 enables the pollutants in the industrial wastewater to be fully mixed with the oxidant, accelerating the chemical reaction. The scraper 7 can scrape off the dirt adhering to the inner wall of the treatment tank, preventing the accumulation of dirt from affecting the treatment effect. The drive end of the drive component is rotatably connected to the rotating shaft 5, which transmits the power output from the motor 4 to the stirring rod 6, causing it to rotate inside the treatment tank, thereby realizing the stirring and mixing of the industrial wastewater. The stirring rod 6 is rotatably connected to both sides of the internal space area of ​​the rotating shaft 5, ensuring that the industrial wastewater can be fully mixed during the stirring process and avoiding uneven mixing in some areas.

[0035] Scrapers 7 are rotatably connected to both sides of the outer wall of the stirring rod 6. During the rotation of the stirring rod 6, the scrapers 7 rotate with the stirring rod 6 and scrape off the dirt attached to the inner wall of the treatment tank. This dirt is mainly formed by the gradual adhesion of suspended solids and sediments in industrial wastewater to the inner wall during long-term treatment. The presence of scrapers 7 can prevent excessive dirt accumulation from affecting the treatment effect, and also reduce the frequency of manual cleaning and reduce maintenance costs. A screen plate 8 is fixedly connected to the internal space of the outer shell 1 of the treatment tank. If the screen plate 8 becomes blocked or damaged during use, it can be easily disassembled and replaced. In order to ensure the normal operation of the screen plate 8, it is necessary to clean and maintain the screen plate 8 regularly.

[0036] The screen plate 8 has screen holes 9 on both the left and right sides of the internal space area. The diameter of the holes is small, which can intercept most of the suspended solids and impurities in the wastewater, and only allow the pre-treated clean water and small molecules to pass through. The drive component includes a motor 4. The motor 4 is externally fixedly connected to the inside of the motor box 3, and the rotating shaft 5 is externally fixedly connected to the inside of the motor 4.

[0037] Reference Figures 2 to 3 Both sides of the internal space of the treatment tank shell 1 are fixedly connected to the baffles 10 to limit the range of movement of certain components inside the treatment tank and prevent them from moving excessively during operation and causing collisions or damage. The bottom space of the treatment tank shell 1 is fixedly connected to the frame 11, which supports and fixes the components inside the treatment tank, such as the cylinder 12 and the push rod 13, providing a stable mounting base for these components and ensuring that they do not shake or shift during operation.

[0038] A cylinder 12 is fixedly connected to the internal space area of ​​the frame 11. By controlling the direction and flow of gas, the cylinder 12 can be precisely controlled to make it reciprocate according to a predetermined stroke and speed. In the processing tank, the cylinder 12 is usually used to drive some parts that require linear motion, such as push rod 13. The top space area of ​​the cylinder 12 is fixedly connected to the bottom side of the processing tank shell 1.

[0039] A push rod 13 is slidably connected to the top space of the cylinder 12 to transmit the linear motion of the cylinder 12 to the movable plate 14, thereby driving the movable plate 14 to move up and down. In the operation of some processing tanks, the up and down movement of the movable plate 14 can be used to control the entry and exit of materials and adjust liquid level parameters. The movable plate 14 is fixedly connected to the top space of the push rod 13 and plays a key role in the processing tank. It can move up and down according to different process requirements to realize the processing and control of materials.

[0040] Reference Figures 3 to 4An adsorption cotton net 15 is fixedly connected to the internal space of the movable plate 14 to perform preliminary adsorption and filtration on the substances entering the treatment tank. When the fluid containing impurities or specific substances passes through the movable plate 14, the adsorption cotton net 15 can intercept and adsorb some of the impurities or target substances, preventing them from further entering other areas of the treatment tank, thereby protecting the subsequent treatment equipment and improving the treatment effect.

[0041] The inner space of the movable plate 14 is fixedly connected to an adsorption cotton net 2 16. The adsorption cotton net 15 can further adsorb and filter the material after the initial filtration, capture the tiny impurities or residual target substances that have escaped the adsorption cotton net 15, improve the adsorption efficiency and precision. Through the synergistic effect of the two-stage adsorption cotton net, impurities in the material can be removed more effectively, and the quality of the processed product can be improved.

[0042] One side of the outer wall of the treatment tank shell 1 is fixedly connected to a drain outlet 17 to discharge the liquid or wastewater generated in the treatment tank in a timely manner. During the treatment process, when a certain amount of liquid or wastewater accumulates in the tank, the drain outlet 17 valve is opened, and the liquid can be discharged through the drain outlet 17 into a designated collection container or drainage pipe. This can keep the liquid level in the treatment tank stable and avoid affecting the treatment effect or causing safety accidents due to excessive liquid level.

[0043] A one-way valve 18 is rotatably connected to the internal space of the drain outlet 17 to prevent backflow of liquid during the drainage process. When liquid is discharged from the treatment tank through the drain outlet 17, the one-way valve 18 opens under the action of liquid pressure, allowing the liquid to flow out smoothly. When the liquid stops flowing or the external pressure is greater than the pressure inside the treatment tank, the one-way valve 18 automatically closes under the action of the spring, preventing the liquid from flowing back into the treatment tank.

[0044] Each side of the top space of the treatment tank shell 1 is fixedly connected to an exhaust port 19 to promptly discharge the gas generated inside the treatment tank to maintain the pressure balance inside the treatment tank. During the treatment process, a certain amount of gas will be generated due to the reaction or stirring of the substances. Bases 20 are fixedly connected to the left and right sides of the bottom space of the treatment tank shell 1 to support the weight of the entire treatment tank, ensuring that the treatment tank remains stable during placement and use, bearing the weight of the treatment tank and its internal substances, and evenly transferring the weight to the ground.

[0045] Working principle: Industrial wastewater enters the treatment tank evenly through the inlet 2 at the top of the outer shell 1. The motor 4 in the motor box 3 rotates after being powered on, and transmits power to the rotating shaft 5 through the transmission mechanism. The rotating shaft 5 drives the stirring rod 6 and the scraper 7 to rotate inside the treatment tank. The rotation of the stirring rod 6 ensures that the pollutants in the industrial wastewater are fully mixed with the oxidant, accelerating the chemical reaction. The scraper 7 rotates along with the stirring rod 6, scraping off the dirt that has been attached to the inner wall of the treatment tank by suspended solids and sediments over a long period of time. The screen plate 8 inside the treatment tank has small-diameter screen holes 9, which can intercept most of the suspended solids and impurities in the wastewater, allowing only the pre-treated clear water and small molecules to pass through. If the screen plate 8 is blocked or damaged, it can be easily disassembled and replaced, and regular cleaning and maintenance are required to ensure normal operation.

[0046] In the processing tank, precise control is achieved by controlling the direction and flow rate of gas in and out. The gas reciprocates according to a predetermined stroke and speed. The cylinder 12 drives the push rod 13, which is slidably connected at the top, to move linearly. The push rod 13 transmits the motion to the movable plate 14 connected at the top, causing the movable plate 14 to move up and down. When fluid containing impurities or specific substances enters the processing tank, the first adsorption cotton net 15 connected inside the movable plate 14 first performs preliminary adsorption filtration, intercepting and adsorbing some impurities or target substances. Then, the second adsorption cotton net 16 performs secondary adsorption filtration on the pre-filtered substance, capturing tiny impurities or residual target substances. Through the synergistic effect of the two-stage adsorption cotton nets, impurities are effectively removed, completing the processing and control of the material.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
