An electrocatalytic oxidation wastewater treatment device

Abstract

This utility model discloses an electrocatalytic oxidation wastewater treatment device, relating to the field of wastewater treatment technology. The device includes a wastewater treatment tank with an adjustment mechanism on its upper part for adjusting the electrode plates. The adjustment mechanism includes a moving component comprising two upper housings mounted on the upper part of the wastewater treatment tank. Synchronous wheels are rotatably mounted on both sides of the two upper housings. This application uses a servo motor to drive the synchronous wheels, which in turn drive the symmetrically distributed fixed frame and electrode plates to move synchronously relative to each other via a synchronous belt. This achieves the interchange of electrode plate positions, ensuring that during long-term use, the electrode plate closer to the wastewater inlet and more susceptible to high-concentration pollutant impact periodically exchanges positions with the electrode plate located on the wastewater discharge side. This effectively avoids excessive wear or performance degradation of one side of the electrode plate, ensuring a uniform workload for each electrode plate and maintaining optimal treatment conditions, significantly improving overall wastewater treatment efficiency and electrode plate lifespan.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an electrocatalytic oxidation wastewater treatment device. Background Technology

[0002] Electrocatalytic wastewater treatment equipment is a novel water treatment technology that utilizes electrochemical reactions to degrade or transform harmful substances in wastewater. It uses an electric field to drive redox reactions on the electrode surface, decomposing pollutants into harmless or low-toxicity substances. It is particularly suitable for treating recalcitrant organic pollutants, such as dyes, pesticides, traditional Chinese medicine, pharmaceutical intermediates, antibiotics, and hormones.

[0003] Referring to the patent document: Patent Publication No. CN112374619B, publication date 2021-05-18, a wastewater treatment device for electrocatalytic oxidation is disclosed, including a support, a top plate, a vertical pipe, and stirring blades. The top plate is fixedly installed on the support, and the vertical pipe is installed on the bottom surface of the top plate through a sealed bearing. Several stirring blades are fixedly installed on the outer periphery of the vertical pipe. A first circular plate is provided inside the vertical pipe, and a second circular plate is provided below the first circular plate. First through holes are respectively opened on both sides of the top surface of the first circular plate, and second through holes corresponding to the first through holes are opened on the top surface of the second circular plate. A first reciprocating screw is provided in one of the first through holes, and a second reciprocating screw is provided in the other second through hole. The first and second reciprocating screws pass through the corresponding second through holes. This invention has an ingenious structure, which can improve the aeration effect, extend the aeration depth, and inject air into wastewater at different depths, thereby improving the aeration effect. Furthermore, it can periodically break up the floating foam on the water surface during use, reducing the re-dissolution of waste gas into the wastewater and improving the aeration efficiency.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found: In existing electrocatalytic oxidation wastewater treatment devices, on the one hand, the electrode plates closer to the wastewater inlet bear a greater workload during wastewater treatment because they come into contact with high-concentration pollutants first. This leads to accelerated wear and a more significant performance decline compared to the electrode plates further downstream. Conversely, the electrode plates on the wastewater discharge side have a relatively lower workload, resulting in an uneven overall efficiency of the electrode plates. This not only affects the wastewater treatment effect but also shortens the lifespan of the electrode plates. On the other hand, during long-term use, impurities easily adhere to the surface of the electrode plates, further affecting the efficiency of the electrocatalytic reaction. However, existing devices typically do not allow for convenient and quick inspection and maintenance of the electrode plates. Operators must drain wastewater to perform these inspections and maintenance, increasing downtime for maintenance and reducing the overall operating efficiency of the wastewater treatment device.

[0005] Therefore, this utility model provides an electrocatalytic oxidation wastewater treatment device. Utility Model Content

[0006] In order to solve the problems of uneven electrode plate workload leading to reduced treatment efficiency and lifespan in existing electrocatalytic oxidation wastewater treatment devices, as well as inconvenient electrode plate maintenance resulting in excessive downtime and low operating efficiency, the purpose of this utility model is to provide an electrocatalytic oxidation wastewater treatment device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electrocatalytic oxidation wastewater treatment device, comprising a wastewater treatment tank, wherein an adjustment mechanism is provided on the upper part of the wastewater treatment tank for adjusting the electrode plates, the adjustment mechanism comprising: The moving component includes two upper housings located on the upper part of the wastewater treatment tank. Synchronous pulleys are rotatably mounted on both sides of the two upper housings. A drive component is located at the lower part of one of the synchronous pulleys. Synchronous belts that cooperate with each other are fitted in the middle of the two sets of synchronous pulleys. A fixed frame that is diagonally distributed is fixedly mounted on both sides of the two synchronous belts. Multiple electrode plates that are evenly distributed are fixedly mounted at the lower part of the four fixed frames. The lifting components are located on both sides of the wastewater treatment tank and are used to adjust the height of its electrode plates.

[0008] Preferably, the lifting assembly includes two support frames fixedly installed at the bottom of the upper housing, and cylinders are fixedly installed on both sides of the wastewater treatment tank, with the drive ends of the two cylinders fixedly installed at the bottom center of the support frames.

[0009] Preferably, the drive assembly includes a servo motor fixedly mounted on one side of the top of the support frame, with the bottom center of one of the synchronous pulleys fixedly mounted on the drive end of the servo motor, and both sets of synchronous pulleys being connected by a transmission belt. A stirring blade is installed on the lower inner surface of the wastewater treatment tank.

[0010] Preferably, the lower surfaces of the two upper housings each have two symmetrically distributed sliding grooves, and the tops of the four fixing brackets each have two symmetrically distributed sliders fixedly installed, with the four sliders slidably engaged inside the sliding grooves.

[0011] Preferably, two symmetrically distributed protective plates are fixedly installed on the lower part of each of the two upper shells, and all four protective plates are in contact with the upper part of the wastewater treatment tank.

[0012] Preferably, two symmetrically distributed inlet pipes are fixedly installed on one side of the lower part of the wastewater treatment tank, and two symmetrically distributed outlet pipes are fixedly installed on the other side of the lower part of the wastewater treatment tank.

[0013] Beneficial effects This invention provides an electrocatalytic oxidation wastewater treatment device. Compared with the prior art, it has the following advantages: 1. This application uses a servo motor to drive a synchronous pulley, which in turn drives the symmetrically distributed fixed frame and electrode plates to move synchronously relative to each other via a synchronous belt. This allows the electrode plates to be interchanged, so that during long-term use, the electrode plates near the wastewater inlet, which are more susceptible to high-concentration pollutant impacts, and the electrode plates located on the wastewater discharge side periodically exchange positions. This effectively avoids excessive wear or performance degradation of the electrode plates on one side, ensuring that the workload of each electrode plate is uniform and that they always maintain the best treatment state, thus significantly improving the overall wastewater treatment efficiency and the service life of the electrode plates.

[0014] 2. This application uses a cylinder to drive the support frame to lift the upper housing and moving components as a whole. When the electrode plate needs to be inspected, maintained, or its usage status needs to be observed, the cylinder pushes the electrode plate away from the wastewater surface. The staff can directly check whether there are impurities or damage on the surface of the electrode plate, and clean, repair, or replace it in time. This avoids the effect of electrocatalytic reaction due to impurities, reduces downtime for maintenance, and ensures the stable and efficient operation of the wastewater treatment device.

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an electrocatalytic oxidation wastewater treatment device, including a wastewater treatment tank 1, with an adjustment mechanism 2 on the upper part of the wastewater treatment tank 1 for adjusting the electrode plate 212. The adjustment mechanism 2 includes: The mobile component 21 includes two upper housings 215 disposed on the upper part of the wastewater treatment tank 1. Synchronous pulleys 211 are rotatably mounted on both sides of the two upper housings 215. A drive component is provided at the lower part of one of the synchronous pulleys 211. Synchronous belts 2111 are fitted in the middle of the two sets of synchronous pulleys 211 for mutual cooperation. The synchronous belts 2111 are made of polyurethane toothed synchronous belts, which have the characteristics of high transmission accuracy, non-slippage and long service life. A fixed frame 213 is fixedly installed on both sides of the two synchronous belts 2111 in a diagonally distributed manner. The fixed frame 213 is welded from high-strength steel, with a stable structure, which can reliably fix the electrode plates 212. Multiple electrode plates 212 are fixedly installed at equal intervals at the lower part of the four fixed frames 213. The motor plates 212 are all fixedly installed at the lower part of the fixed frame 213 by bolts. Lifting components 22 are installed on both sides of the wastewater treatment tank 1 to adjust the height of its electrode plates 212.

[0023] The lifting assembly 22 includes two support frames 217 fixedly installed at the bottom of the upper housing 215. Cylinders 221 are fixedly installed on both sides of the wastewater treatment tank 1. The drive ends of the two cylinders 221 are fixedly installed at the bottom center of the support frame 217. The cylinders 221 can be Japanese SMC standard cylinders, model JMDBB32-50-M9BW. Driven by the cylinders 221, the support frame 217 can be moved up and down, thereby adjusting the height of the electrode plate 212, making it convenient to observe whether there are impurities attached to the outer surface of the electrode plate 212.

[0024] The drive assembly includes a servo motor 216 fixedly mounted on one side of the top of the support frame 217. One of the synchronous pulleys 211 is fixedly mounted on the drive end of the servo motor 216 at the bottom center. The servo motor 216 is a Kollmorgen AKM2G servo motor, which drives the synchronous pulley 211 to rotate. Both sets of synchronous pulleys 211 are connected by a transmission belt. An agitator 222 is installed on the lower inner surface of the wastewater treatment tank 1. The rotation of the agitator 222 can agitate the wastewater in the wastewater treatment tank 1 to ensure that the additives such as hydrogen peroxide can be uniformly mixed when they enter the wastewater treatment tank 1.

[0025] Two symmetrically distributed grooves 2141 are provided on the lower surface of each of the two upper housings 215. Two symmetrically distributed sliders 214 are fixedly installed on the top of each of the four fixed frames 213. The four sliders 214 are slidably locked inside the grooves 2141. With the cooperation of the sliders 214 and the grooves 2141, the fixed frames 213 can be supported and limited. While ensuring the stable movement of the fixed frames 213, the fixed frames 213 can be supported and fixed, so that they are suspended from the lower part of the upper housings 215.

[0026] Two symmetrically distributed protective plates 2151 are fixedly installed on the lower part of each of the two upper shells 215. All four protective plates 2151 are in contact with the upper part of the wastewater treatment tank 1. The protective plates 2151 are located on the outside of both sides of the wastewater treatment tank 1 and can limit their movement, ensuring that the electrode plate 212 can be stably supported after the upper shell 215 is placed in the wastewater treatment tank 1.

[0027] Two symmetrically distributed inlet pipes 11 are fixedly installed on one side of the lower part of the wastewater treatment tank 1, and two symmetrically distributed outlet pipes 12 are fixedly installed on the other side of the lower part of the wastewater treatment tank 1. The inlet pipes 11 and outlet pipes 12 are used for the discharge and discharge of wastewater, respectively.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, after prolonged use, the servo motor 216 drives one of the synchronous pulleys 211 to rotate. Under the transmission of its belt, the two synchronous pulleys 211 on one side rotate synchronously. Through the cooperation of the synchronous pulleys 211 on both sides and the synchronous belt 2111, the two synchronous belts 2111 rotate synchronously, causing the two fixed frames 213 on both sides of the synchronous belt 2111 to move synchronously relative to each other. This causes the two sets of electrode plates installed at the bottom to move synchronously relative to each other, exchanging their positions. By exchanging their positions, the set of electrode plates 212 that was originally close to the wastewater inlet moves to the wastewater discharge side, while the electrode plate 212 on the wastewater discharge side moves to the wastewater inlet side, ensuring that the electrode plate 212 is always in the best treatment state. Meanwhile, under long-term use, the support frame 217 can be driven to move upward by two cylinders 221 in sync, which in turn drives the upper housing 215 to move upward, so that the moving component 21 moves upward away from the upper part of the wastewater treatment tank 1, thereby causing the electrode plate 212 to leave the wastewater, so that the usage of the electrode plate 212 can be easily observed, so as to adjust the position of the electrode plate 212.
