Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to an online sodium hypochlorite generator with multiple concentrations. Background Technology

[0002] In the chemical and water treatment fields, sodium hypochlorite, as a strong oxidant, possesses highly efficient and broad-spectrum bactericidal and disinfecting capabilities, and is widely used in drinking water disinfection, industrial circulating water treatment, swimming pool disinfection, and wastewater treatment. Traditional sodium hypochlorite preparation methods mostly employ offline production models, meaning that a sodium hypochlorite solution of a certain concentration is prepared in advance at a factory or specific production site, and then stored, transported, and used.

[0003] However, this offline production method has the following significant problems: Concentration is difficult to control precisely. The concentration of sodium hypochlorite solution produced offline is usually fixed, making it difficult to meet the diverse concentration requirements of different application scenarios. In actual use, it is often necessary to dilute or mix solutions of different concentrations to achieve the desired concentration, which not only increases operational complexity but may also lead to inaccurate concentration control.

[0004] To address the aforementioned issues, this invention proposes an online sodium hypochlorite generator with multiple concentrations. By integrating a mixing mechanism and an electrolysis component, it aims to achieve online generation and real-time concentration control of sodium hypochlorite solution to meet the needs of different application scenarios.

[0005] To address the shortcomings of existing technologies, this invention provides an online sodium hypochlorite generator with multiple concentrations, capable of generating sodium hypochlorite solutions of the required concentrations in real time, offering advantages such as high efficiency, energy saving, and precise controllability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an online sodium hypochlorite generator with multiple concentrations, comprising a solution tank, an electrolysis tank at the bottom of the solution tank, a mixing mechanism on the surface of the electrolysis tank, and an electrolysis assembly inside the electrolysis tank; The mixing mechanism is used to mix and adjust the concentration of the raw materials for generating sodium hypochlorite. The mixing mechanism includes a mounting frame fixed to the upper surface of the electrolysis tank.

The solution tank is rotatably connected to the upper surface of the electrolysis tank. The bottom ends of the two rotary feed pipes extend into the interior of the solution tank, and several stirring blades are fixedly connected to the surface of each of the two rotary feed pipes. A first drive motor is fixedly installed on the upper surface of the electrolysis tank. A first drive gear is fixedly connected to the rotating shaft of the first drive motor. A gear ring is fixedly connected to the surface of the solution tank, and the first drive gear meshes with the gear ring.

[0007] Preferably, a drive synchronous pulley is fixedly provided on the top of the drive shaft, a driven synchronous pulley is fixedly connected to the surface of the rotating feed pipe, and a drive belt is installed between the drive synchronous pulley and the driven synchronous pulley.

[0008] Preferably, the two drive shafts are symmetrically distributed on the left and right sides of the solution tank. The bottom end of each drive shaft is fixedly connected to a drive gear, the position of which corresponds to the gear ring, and both drive gears mesh with the gear ring.

[0009] Preferably, an annular limiting plate is fixedly connected to the upper surface of the electrolysis tank, the position of the annular limiting plate corresponds to the solution tank, and the solution tank is slidably connected to the inner surface of the annular limiting plate.

[0013] Compared with the prior art, this utility model provides an online sodium hypochlorite generator with multiple concentrations, which has the following beneficial effects: 1. High-efficiency mixing and concentration control: This device utilizes a mixing mechanism designed with a first drive motor to rotate the solution tank, simultaneously driving the rotating feed pipe and its surface stirring blades to agitate the solution tank. Furthermore, a drive belt synchronizes the rotation of the drive shaft and the rotating feed pipe, creating relative rotation between the feed pipe, stirring blades, and the solution tank, further enhancing the mixing effect. This design not only achieves efficient mixing of raw materials but also allows for flexible adjustment of the sodium hypochlorite concentration according to actual needs, improving production efficiency and product quality stability. The sodium hypochlorite concentration can be adjusted online by regulating the ratio of dilute to concentrated brine in the raw material supply system and the current intensity of the electrolysis tank.

[0014] 2. High degree of automation and ease of operation: The coordinated operation of the first and second drive motors achieves a fully automated process from raw material mixing to electrolysis to sodium hypochlorite production. This simplifies the operation, reduces the need for manual intervention, and improves production efficiency and safety.

Detailed Implementation

[0017] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0018] This utility model provides a technical solution: Please see Figures 1-4A multi-concentration sodium hypochlorite online generator is disclosed. The device mainly consists of a solution tank 1, an electrolysis tank 2, a mixing mechanism 3, an electrolysis assembly 4, an annular limiting plate 5, a drain pipe 6, and a control system (not shown in the figure). The solution tank 1 is located above the electrolysis tank 2 and is connected to the electrolysis tank 2 via a rotary connection, enabling a certain degree of rotational movement.

[0019] The electrolysis tank 2 is equipped with a mixing mechanism 3 and an electrolysis assembly 4 for mixing raw materials and electrolytic reaction. An annular limiting plate 5 is fixedly connected to the upper surface of the electrolysis tank 2 to limit the rotation range of the solution tank 1. A drain pipe 6 is located on the side of the electrolysis tank 2 to drain the generated sodium hypochlorite solution.

[0020] It is worth noting that the mixing mechanism 3 is mainly used for mixing and adjusting the concentration of the raw materials for generating sodium hypochlorite. The mixing mechanism 3 includes a mounting frame 301 fixed to the upper surface of the electrolysis tank 2. Two drive shafts 302 are symmetrically rotatably connected to the lower surface of the mounting frame 301. A drive synchronous wheel 308 is fixedly installed at the top of the drive shaft 302. Two rotary feed pipes 303 are rotatably connected to the upper surface of the mounting frame 301. A driven synchronous wheel 309 is fixedly connected to the surface of the rotary feed pipe 303. The drive synchronous wheel 308 and the driven synchronous wheel 309 rotate synchronously through a drive belt 310. The bottom ends of both rotary feed pipes 303 extend into the interior of the solution tank 1, and several stirring blades 304 are fixedly connected to their surfaces. When the drive shafts 302 rotate, the rotary feed pipes 303 rotate synchronously through the drive belt 310, thereby driving the stirring blades 304 to stir inside the solution tank 1, achieving mixing of the raw materials.

[0021] In addition, a first drive motor 305 is fixedly mounted on the upper surface of the electrolysis tank 2, and a first drive gear 306 is fixedly connected to the rotating shaft of the first drive motor 305. A gear ring 307 is fixedly connected to the surface of the solution tank 1, and the first drive gear 306 meshes with the gear ring 307. When the first drive motor 305 starts, the first drive gear 306 drives the gear ring 307 and the solution tank 1 to rotate, further enhancing the mixing effect. At the same time, transmission gears 311 are fixedly connected to the bottom ends of the two transmission shafts 302. The positions of the transmission gears 311 correspond to the gear rings 307, and both transmission gears 311 mesh with the gear rings 307. This design allows the transmission shafts 302 to generate additional stirring power for the solution tank 1 while rotating, through the meshing action of the transmission gears 311 and the gear rings 307, further improving the mixing efficiency.

[0022] Both rotary feed pipes 303 are fixedly connected to feed hoppers 312 at their top ends for adding raw materials into the device. The raw materials can enter the rotary feed pipes 303 through the feed hoppers 312 and be fully mixed with the liquid in the solution tank 1 under the action of the stirring plate 304.

[0023] It is worth noting that the electrolysis assembly 4 is mainly used to electrolyze the mixed raw materials to generate a sodium hypochlorite solution. Its structure includes a protective shell 401 fixed to the back of the electrolysis tank 2, with a second drive motor 402 fixedly connected to the inner wall of the protective shell 401. A second drive gear 403 is fixedly connected to the rotating shaft of the second drive motor 402. Two rotating shafts 404 are rotatably connected to the inner wall of the electrolysis tank 2, and a fixing sleeve 405 is fixedly connected to the surface of the rotating shafts 404. Several electrolysis rods 406 are evenly distributed on the surface of the fixing sleeve 405. When the second drive motor 402 starts, it drives the two rotating shafts 404 and the electrolysis rods 406 to rotate synchronously via the second drive gear 403. This design allows the electrolysis rods 406 to uniformly stir the electrolyte during electrolysis, improving electrolysis efficiency.

[0024] The rear ends of both rotating shafts 404 extend into the interior of the protective housing 401 and are fixedly connected to driven gears 407. The two driven gears 407 are symmetrically distributed on both sides of the second drive gear 403 and mesh with the second drive gear 403. This design ensures that the rotating shafts 404 and the electrolytic rod 406 can rotate stably and synchronously.

[0025] It should be noted that the annular limiting plate 5 is fixedly connected to the upper surface of the electrolysis tank 2, and its inner surface is slidably connected to the solution tank 1. The design of the annular limiting plate 5 limits the rotation range of the solution tank 1 while ensuring its stability during rotation. The drain pipe 6 is located on the side of the electrolysis tank 2 and is used to drain the generated sodium hypochlorite solution. A valve (not shown in the figure) can be installed on the drain pipe 6 to control the discharge rate and volume of the solution.

[0026] It should be further noted that this device is also equipped with a control system (not shown in the figure) for automated operation and precise control. The control system can use a PLC (Programmable Logic Controller) as the core controller, and uses sensors to monitor parameters such as raw material flow rate, electrolyte concentration, and electrolysis current in real time. Based on the set target concentration value, the control system can automatically adjust parameters such as the raw material supply, the magnitude of the electrolysis current, and the rotation speed of solution tank 1 to ensure that the generated sodium hypochlorite solution meets the preset concentration requirements.

[0027] The control system can also be connected to a remote monitoring terminal to achieve remote monitoring and fault diagnosis functions. Operators can view the device's operating status, concentration data, and other information in real time through the remote monitoring terminal, and can also perform remote control and parameter adjustments. When a fault occurs in the device, the control system can automatically issue an alarm signal and display the fault location and cause, facilitating timely troubleshooting by maintenance personnel.

[0028] When using this device, the raw material (such as dilute brine, concentrated brine, etc.) is first added to the rotary feed pipe 303 through the feed hopper 312. Then, the first drive motor 305 and the second drive motor 402 are started to make the solution tank 1 and the electrolysis rod 406 start rotating. At the same time, the control system automatically adjusts the supply of raw materials and the magnitude of the electrolysis current according to the set target concentration value. Under the action of the rotary feed pipe 303 and the stirring plate 304, the raw material is fully mixed with the liquid in the solution tank 1 and flows through the electrolysis rod 406 to carry out the electrolysis reaction. The generated sodium hypochlorite solution is discharged from the device through the drain pipe 6 for subsequent use.

[0029] Throughout the process, the control system monitors various parameters in real time and adjusts them as needed to ensure that the generated sodium hypochlorite solution meets the preset concentration requirements. Simultaneously, operators can view the device's operating status and remotely control it via a remote monitoring terminal.

[0030] In summary, this online sodium hypochlorite generator with multiple concentrations achieves the online generation of sodium hypochlorite solutions with multiple concentrations through the integrated design of a mixing mechanism and an electrolysis component.

[0031] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
