Description
Technical Field
[0001] The utility model relates to the field of electrolytic manganese, in particular to a novel diaphragm frame cleaning device for electrolytic manganese. Background Art
[0002] In the electrolytic section of electrolytic manganese production, a diaphragm bag is usually used to separate the cathode and anode in the electrolytic cell to ensure the smooth progress of the electrolytic reaction. However, during the electrolysis process, due to the occurrence of side reactions and the temperature difference in the electrolytic cell, a thick layer of crystals will gradually adhere to the surface of the electrolytic diaphragm frame and the diaphragm bag. These crystals mainly include compounds such as calcium sulfate and magnesium sulfate, which greatly affect the permeability of manganese ions, thereby directly affecting the output of electrolytic manganese. According to the test results, the crystals attached to the diaphragm bag and the diaphragm frame contain about 26.00% elemental calcium and about 1.10% elemental magnesium.
[0003] In the traditional treatment method, the operator usually needs to manually remove the diaphragm bag from the diaphragm frame, and then soak it in oxalic acid solution for a period of time to dissolve the crystals attached to the surface. After that, the soaked diaphragm bag is stirred and cleaned using a washing machine, and the attachments on the diaphragm frame are manually scraped off with a spatula. However, this method has many shortcomings. First, the process requires high physical strength from the operator and is labor-intensive. Secondly, due to the cumbersome and complicated treatment process and the long treatment time, the downtime of the entire electrolysis section is extended, which in turn increases the production cost. In addition, during the manual operation, due to mistakes or carelessness, the diaphragm frame and diaphragm bag are easily damaged, which not only increases the material cost, but also may affect the production progress.
[0004] Therefore, the prior art urgently needs a cleaning method with high automation, high cleaning efficiency and no damage to the diaphragm frame and diaphragm bag, so as to overcome the above-mentioned shortcomings in the traditional method and improve the overall efficiency and economic benefits of electrolytic manganese production. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a novel diaphragm frame cleaning device for electrolytic manganese.
[0006] The utility model is realized by the following technical solutions:
[0007] The utility model discloses a novel diaphragm frame cleaning device for electrolytic manganese, comprising cleaning tanks, wherein three cleaning tanks are provided and arranged in a linear array in sequence; an aeration mechanism is provided in the cleaning tanks; an automatic frame moving mechanism is provided above the three cleaning tanks for transferring the diaphragm frame in the three cleaning tanks; the automatic frame moving mechanism is connected with a walking track; hydrogen peroxide and sulfuric acid solution are introduced into one of the three cleaning tanks, clean water is introduced into the second one, and sodium hydroxide solution is introduced into the third one.
[0008] The design of this utility model aims to improve the cleaning efficiency of diaphragm frames during the electrolytic manganese production process. The linear arrangement of the three cleaning tanks enables the cleaning process to proceed continuously, avoiding repeated handling and operations. The aeration mechanism in the cleaning tank enhances the fluidity and reaction efficiency of the cleaning liquid by introducing bubbles into the tank, and can more effectively remove the attachments on the diaphragm frame. The existence of the automatic frame transfer mechanism greatly reduces the complexity of manual operations. The diaphragm frame is automatically transferred between different cleaning tanks through the walking track, ensuring that each cleaning step can be executed smoothly and accurately. Different chemical solutions (hydrogen peroxide and sulfuric acid solution, clear water, sodium hydroxide solution) are introduced into the three cleaning tanks respectively, and each solution plays a different cleaning role, targeting different types of attachments on the diaphragm frame to provide a comprehensive cleaning effect.
[0009] Furthermore, the above-mentioned cleaning tank includes a tank body, a liquid inlet, a liquid outlet, and a support grid; the upper half of the tank body is in the shape of a cuboid, and the lower half is in the shape of an inverted frustum; the liquid inlet is arranged in the upper half of the tank body, and the liquid outlet is arranged at the bottom of the tank body; a support grid is arranged at the connection of the upper and lower parts of the tank body to provide support for the diaphragm frame placed in the cleaning tank.
[0010] The design structure of the cleaning tank takes into account the liquid flow and discharge requirements during the cleaning process. The upper half of the tank body is in the shape of a cuboid, making the cleaning tank have a larger capacity and can accommodate larger diaphragm frames and cleaning liquid; the lower half is in the shape of an inverted frustum, and the conical structure is helpful for liquid discharge. The liquid inlet is arranged in the upper half of the tank body, facilitating the rapid entry of the cleaning liquid, while the liquid outlet at the bottom ensures the rapid discharge of the cleaning liquid, avoiding liquid retention during the cleaning process. The support grid is exactly located at the connection of the upper and lower parts of the tank body, which can provide stable support for the diaphragm frame, preventing the diaphragm frame from directly contacting the bottom of the tank, so that the cleaning liquid can fully cover all parts of the diaphragm frame and improve the cleaning effect.
[0011] Furthermore, the above-mentioned aeration mechanism includes side aeration coiled pipes, a lower aeration coiled pipe, and an air inlet hose; there are two side aeration coiled pipes, which are arranged in mirror symmetry and are respectively fixed on two opposite inner walls of the cleaning tank; the lower aeration pipe is vertically arranged with the two side aeration coiled pipes, is located between the two side aeration coiled pipes, and is at the lower end position of the two side aeration coiled pipes, and is fixedly connected inside the cleaning tank; the air inlets of the side aeration coiled pipes and the lower aeration coiled pipe are respectively connected in communication with the air inlet hose, and the air inlet hose is connected to a compressed air source. A number of through holes are respectively arranged on the side aeration coiled pipes and the lower aeration coiled pipe.
[0012] The function of the aeration mechanism is to inject bubbles into the cleaning liquid to enhance the fluidity and mixing effect of the liquid, thereby improving the efficiency of the chemical reaction. The symmetric arrangement of the side aeration coils ensures that the bubbles can be evenly distributed in the cleaning tank, ensuring that the cleaning liquid can fully contact the surface of the diaphragm frame. The lower aeration coil further increases the fluidity of the cleaning liquid by generating bubbles from the bottom upwards, enabling the substances deposited at the bottom of the tank to be effectively removed. The intake hose is connected to the compressed air source to provide a continuous air flow, enabling the aeration process to proceed stably for a long time. This design ensures that the aeration effect of the diaphragm frame during the cleaning process is maximized, significantly improving the cleaning efficiency and effect.
[0013] Furthermore, the above-mentioned automatic frame transfer mechanism includes a moving platform, a lifting platform, a lifting motor, a lead screw, and a clamping mechanism; the above-mentioned moving platform is a plate-shaped part, which is assembled and connected with the walking track and can move linearly along the walking track; the above-mentioned lifting platform is a rectangular frame, and the vertical rods on the four sides of the rectangular frame are arranged perpendicular to the moving platform and are slidably connected to the moving platform; the above-mentioned lifting motor is fixedly connected to the moving platform, and the output shaft of the lifting motor is coaxially and fixedly connected to the lead screw; the upper plate is fixedly connected to the upper rectangular frame above the above-mentioned lifting platform, and the lower plate is fixedly connected to the lower rectangular frame below; the above-mentioned lead screw passes through the upper plate upwards and is in threaded fit with the preset sleeve on the upper plate; the above-mentioned clamping mechanism is arranged on the lower plate and is used for clamping the diaphragm frame.
[0014] The automatic frame transfer mechanism is one of the core components of the entire cleaning device and is responsible for automatically transferring the diaphragm frame between different cleaning tanks. The moving platform moves linearly along the walking track to achieve the horizontal movement of the diaphragm frame, while the lifting platform realizes the vertical movement of the diaphragm frame through the lifting motor and the lead screw. The precise cooperation between the lead screw and the lifting motor ensures the smooth operation of the lifting platform and can accurately control the height of the diaphragm frame. The clamping mechanism firmly clamps the diaphragm frame through the interaction between the central gear and the clamping arm, preventing it from sliding or displacing during the moving process. The entire frame transfer process is precisely controlled by the control system to ensure that the diaphragm frame can be quickly and accurately moved to the designated cleaning tank to complete each cleaning step.
[0015] Further, the clamping mechanism includes a central gear, a first clamping arm, a second clamping arm, and a clamping head; the central gear is rotatably connected to the lower plate, and the central axis of the central gear is perpendicular to the lower plate; the first clamping arm includes a cross bar and a vertical bar, the cross bar is perpendicular to the vertical bar, the cross bar is parallel to the traveling direction of the automatic frame transfer mechanism, and the vertical bar is parallel to the lifting direction of the lifting platform. The end of the cross bar that is not connected to the vertical bar is provided as a rack and is meshed and assembled with the central gear; several sleeves are fixedly connected to the lower plate, and the cross bar of the first clamping arm passes through the sleeves and is slidably connected to the lower plate; the central gear is driven to rotate by a stepping motor fixedly connected to the lower plate; the structure of the second clamping arm is centrosymmetric with that of the first clamping arm and is centrosymmetrically arranged along the central axis of the central gear; there are two clamping heads, which are respectively fixedly connected to the ends of the vertical bars of the first clamping arm and the second clamping arm; the clamping head is a ninety-degree bent plate-shaped part, and the bending directions of the two clamping heads are symmetrical and both bend towards the central gear.
[0016] The clamping mechanism realizes the firm grasping of the diaphragm frame through precise mechanical design. The central gear is the key component of the system. It converts the rotational motion of the motor into the linear motion of the clamping arm through meshing with the rack. The symmetrical design of the first clamping arm and the second clamping arm ensures the uniform distribution of the clamping force, ensuring the stability of the diaphragm frame during the clamping process. The clamping head is designed with a ninety-degree bend, which can closely fit the edge of the diaphragm frame, providing a more stable clamping effect. The design of the entire clamping mechanism aims to always keep the diaphragm frame stable during the complex movement and cleaning process, preventing it from tilting or loosening, thereby improving the safety and reliability of the entire cleaning process.
[0017] Further, the support grid is composed of several vertically and crosswise arranged rods, and the rods in the same direction are arranged at equal intervals; several support blocks are arranged on the support grid, one end of the support block is fixedly connected to the support grid, and the other end is provided as a tip for supporting the diaphragm frame.
[0018] The beneficial effects of the present utility model are as follows:
[0019] High degree of automation: By adopting a control system to automatically control the transfer process of the diaphragm frame and the continuous process of aeration cleaning, manual intervention is greatly reduced, the operation efficiency is improved, and the labor cost is reduced. The control system can precisely control the time and conditions of each cleaning step to ensure the stability and consistency of the cleaning process.
[0020] Significant cleaning effect: The device adopts a three-stage cleaning tank design, which respectively introduces hydrogen peroxide and sulfuric acid solution, clean water and sodium hydroxide solution. Combined with aeration cleaning, it can not only effectively remove impurities such as manganese dioxide, manganese, calcium sulfate, magnesium sulfate, etc. attached to the surface of the diaphragm frame, but also finally convert it into a viscous precipitate through the double decomposition reaction of sodium hydroxide solution and acidic substances, thereby achieving a thorough cleaning effect.
[0021] Efficient cleaning process: The design of the aeration mechanism makes the cleaning solution evenly distributed on the surface of the diaphragm frame, and through the disturbance of bubbles, the efficiency of the chemical reaction is enhanced and the removal of impurities is accelerated. At the same time, the precise transfer function of the automatic frame-shifting mechanism makes the transition between each cleaning step fast and smooth, improving the overall cleaning speed.
[0022] Easy maintenance: The device has a reasonable structural design, and the modular design of the cleaning tank, aeration mechanism, automatic frame-moving mechanism, etc. is convenient for disassembly and maintenance. The control system can monitor the equipment status in real time through the human-machine interface, which is convenient for operators to debug and perform daily maintenance on the equipment.
[0023] In summary, the utility model significantly improves the cleaning efficiency and effect of the diaphragm frame by integrating automatic control and precise cleaning, while saving resources and enhancing the safety and maintainability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

A number of through holes are respectively arranged on the side aeration coils 21 and the lower aeration coil 22.
[0042] The function of the aeration mechanism 2 is to inject bubbles into the cleaning liquid to enhance the fluidity and mixing effect of the liquid, thereby improving the efficiency of the chemical reaction. The symmetrical arrangement of the side aeration coils 21 ensures that the bubbles can be evenly distributed in the cleaning tank 1, ensuring that the cleaning liquid can fully contact the surface of the diaphragm frame A. The lower aeration coil 22 further increases the fluidity of the cleaning liquid by generating bubbles from the bottom upwards, so that the substances deposited at the bottom of the tank can also be effectively removed. The air inlet hose 23 is connected to a compressed air source to provide a continuous air flow, enabling the aeration process to proceed stably for a long time. This design ensures that the aeration effect of the diaphragm frame A during the cleaning process is maximized, significantly improving the cleaning efficiency and effect.

[0044] The automatic frame shifting mechanism 3 is one of the core components of the entire cleaning device and is responsible for automatically transferring the diaphragm frame A between different cleaning tanks 1. The moving platform 31 moves linearly along the walking track 4 to achieve the horizontal movement of the diaphragm frame A, while the lifting platform 32 realizes the vertical movement of the diaphragm frame A through the lifting motor 33 and the lead screw 34. The precise cooperation between the lead screw 34 and the lifting motor 33 ensures the smooth operation of the lifting platform 32 and can accurately control the height of the diaphragm frame A. The clamping mechanism 35 firmly clamps the diaphragm frame A through the interaction between the central gear 351 and the clamping arms, preventing it from sliding or displacing during the movement.

[0048] When using:
[0049] The diaphragm frame A is transferred to one of the three cleaning tanks 1 by using the automatic frame moving mechanism 3. Hydrogen peroxide and sulfuric acid solution are introduced into the cleaning tank 1. The aeration mechanism 2 in the cleaning tank 1 is turned on to perform aeration cleaning, so that the manganese dioxide attached thereto reacts with the hydrogen peroxide and sulfuric acid to form manganese sulfate, and the manganese attached thereto reacts with the sulfuric acid to form manganese sulfate;
[0050] Then, the diaphragm frame A is transferred to the next cleaning tank 1 by using the automatic frame moving mechanism 3. Clean water is introduced into the cleaning tank 1. The aeration mechanism 2 in the cleaning tank 1 is turned on to perform aeration cleaning to wash away the acid attached to the surface.
[0051] Then, the diaphragm frame A is transferred to the next cleaning tank 1 by using the automatic frame moving mechanism 3. Sodium hydroxide solution is introduced into the cleaning tank 1. The aeration mechanism 2 in the cleaning tank 1 is turned on to perform aeration cleaning, so that sodium hydroxide and calcium sulfate and magnesium sulfate undergo double decomposition reaction, so that the calcium sulfate and magnesium sulfate crystals attached to the diaphragm frame A are converted into sticky hydroxide precipitates, and the cleaning is completed.
[0052] The aeration cleaning in the cleaning tank 1 with hydrogen peroxide and sulfuric acid solution lasts for 10-20 minutes; the aeration cleaning in the cleaning tank 1 with clean water lasts for 10-20 minutes; the aeration cleaning in the cleaning tank 1 with sodium hydroxide solution lasts for 30-60 minutes.
[0053] The transfer process of the above-mentioned diaphragm frame A and the continuous process of aeration cleaning are automatically controlled by the control system. The control system during the transfer process of diaphragm frame A and the continuous process of aeration cleaning is mainly responsible for the automated operation and coordination of the entire cleaning device. This control system includes the following main modules:
[0054] Central Processing Unit (CPU): The core component of the control system is the Central Processing Unit (CPU). It receives input signals from various sensors and actuators, and executes control tasks according to the preset program logic. The CPU is responsible for processing the transfer instructions of diaphragm frame A during the cleaning process, the start and stop of aeration cleaning, and the monitoring of the solution status in each cleaning tank.
[0055] Sensor module:
[0056] Position sensor: Installed on the walking track and lifting platform, it is used to detect the position of diaphragm frame A and its transfer between different cleaning tanks. The position sensor feeds back the real-time position information to the CPU to ensure that the diaphragm frame moves accurately into the designated cleaning tank.
[0057] Liquid level sensor: Monitors the liquid level of the solution in the cleaning tank to ensure that the solution in the tank is at an appropriate height during the cleaning process. If the liquid level is too low or too high, the CPU will issue a warning or automatically adjust the switch states of the liquid inlet and outlet.
[0058] Temperature sensor: Used to monitor the temperature of the solution in each cleaning tank to ensure that the reaction conditions are within the optimal range. Especially in the cleaning steps using hydrogen peroxide and sulfuric acid, temperature control is crucial for the effectiveness of the reaction.
[0059] Actuator module:
[0060] Motor control unit: This unit controls the movement of the mobile platform and the lifting platform, including the movement on the walking track and the lifting of the diaphragm frame. The motor control unit receives instructions from the CPU and precisely controls the start, stop, speed, and direction of the motor.
[0061] Valve controller: Controls the opening and closing of the valves at the liquid inlets and outlets of each cleaning tank to regulate the liquid flow in the cleaning tank. In addition, the valve controller also manages the intake valves in the aeration system to control the inflow of compressed air.
[0062] Aeration controller: Responsible for controlling the operation of the aeration mechanism, including the start and stop of the aeration coil and the adjustment of the aeration volume. The aeration controller ensures that an appropriate aeration intensity is maintained during the designated cleaning stage according to the instructions from the CPU.
[0063] Human-Machine Interface (HMI): The control system is configured with a Human-Machine Interface (HMI). Operators can monitor the entire cleaning process through the HMI and adjust the cleaning parameters. The HMI display screen can show the real-time position of the diaphragm frame, the status of each cleaning tank (including liquid level, temperature, etc.), the countdown of the cleaning time, and the working status of the aeration system. Operators can perform manual operations through the HMI or interrupt the automatic cleaning process when needed.
[0064] Program Control and Logic Design: The program of the control system presets the logic of multiple cleaning steps, including the transfer sequence of the diaphragm frame, the aeration duration of each cleaning tank, the solution replacement time, etc. The program will be adjusted according to different cleaning requirements. For example, when cleaning a diaphragm frame with higher cleaning difficulty, the cleaning time can be increased or the aeration intensity can be improved.
[0065] Safety System: The control system also integrates a variety of safety measures, including overload protection, emergency stop button, liquid level abnormal alarm, etc. When the system detects any abnormal situation (such as overheating of the solution, too low liquid level or motor overload), the safety system will immediately interrupt the cleaning process and notify the operator to take measures through the HMI.
[0066] After the above-mentioned aeration cleaning of the diaphragm frame A in the cleaning tank 1 filled with sodium hydroxide solution lasts for 30 - 60 minutes, it returns to the cleaning tank 1 filled with clean water for aeration cleaning for 10 - 20 minutes to wash off the attached alkali and complete the cleaning.
[0067] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features.
