Description

Technical Field

[0001] The utility model belongs to the technical field of selenium dioxide liquid extraction equipment, and particularly relates to an automatic selenium dioxide adding device for an electrolytic manganese bath. Background Art

[0002] Selenium dioxide is an inorganic compound with the chemical formula SeO₂. Selenium dioxide usually appears as a white crystalline powder, and its vapor is yellowish-green. It can be liquefied under pressure to obtain a yellow liquid, and it will sublime when heated to 315 °C under normal pressure to obtain a green vapor. It is easily soluble in water and polar organic solvents such as ethanol and acetone.

[0003] Selenium dioxide is an oxidant, catalyst, and chemical reagent in organic compounds, and it is also a raw material for manufacturing various inorganic selenium compounds. In the electrolytic manganese industry, selenium dioxide is an essential raw material. Approximately 1 kilogram of selenium dioxide is required to produce one ton of electrolytic manganese (the specific consumption may vary depending on the process). In addition, it is also used in the production of sodium selenite in the feed industry and as a selenium fertilizer raw material for selenium-containing crops in the agricultural industry. Selenium dioxide is also used in fields such as analysis, verification of alkaloids, production of other selenium compounds, and high-purity selenium.

[0004] Selenium dioxide liquid is usually stored in a container, and workers use traditional pipelines and valves to extract the liquid. When the liquid needs to be extracted, the valve is opened, and when it is not needed, the valve is closed. Although the overall operation is relatively simple, it is difficult to accurately control the extraction amount of selenium dioxide, resulting in a certain deviation between the obtained liquid volume and the required value. If the liquid volume is too much, it is easy to overflow and there are certain safety hazards. If it is too little, the operation needs to be carried out again, which is troublesome.

[0005] Therefore, a more reasonable technical solution is still needed to accurately control the extraction amount of selenium dioxide. Content of the Utility Model

[0006] The purpose of the utility model is to provide an automatic selenium dioxide adding device for an electrolytic manganese bath, which can accurately control the extraction amount of selenium dioxide and ensure the extraction quality and efficiency.

[0018] In a possible design, the stirring device includes:

Detailed implementation manners

[0034] The following further elaborates on the present utility model in conjunction with the drawings and specific embodiments. It should be noted here that the description of these embodiment manners is for helping to understand the present utility model, but does not constitute a limitation to the present utility model.

[0035] The specific structural and functional details disclosed herein are only used to describe the embodiments of the examples of the present utility model. However, the present utility model can be embodied in many alternative forms and should not be construed as limited to the embodiments described herein.

[0036] According to the specific implementation manners of the present disclosure, a selenium dioxide automatic adding device for an electrolytic manganese bath is provided. Among them, Figure 1 and Figure 2 shows one of the specific embodiments.

[0037] Referring to Figure 1 and Figure 2 as shown, the selenium dioxide automatic adding device for an electrolytic manganese bath includes: a storage tank 1 provided with a liquid discharge port 11 for emptying the storage tank 1 or performing maintenance when needed; a stirring device 2 arranged on the storage tank 1 for stirring the liquid in the storage tank 1; a metering filling device 3 connected to the storage tank 1 through a diversion pipe 35, and the metering filling device 3 is used for pouring the liquid into an external container; wherein, a liquid supplement angle seat valve 36 is arranged on the diversion pipe 35; a liquid level height detection device 4 arranged in the storage tank 1 for detecting the current height information of the liquid in the storage tank 1; and a controller communicatively connected to the stirring device 2, the metering filling device 3, the liquid supplement angle seat valve 36 and the liquid level height detection device 4, and controlling the stirring device 2, the metering filling device 3 and the liquid supplement angle seat valve 36 to perform corresponding actions according to the received current height information of the liquid.

[0038] The stirring device 2 is arranged on the storage tank 1, which is used to ensure the uniform mixing of the liquid in the storage tank 1, avoid precipitation or stratification, and ensure the accuracy and consistency of subsequent operations. It is connected to the storage tank 1 through the diversion pipe 35, and can accurately control and inject a certain amount of liquid into the target container. The liquid supplement angle seat valve 36 arranged on the diversion pipe 35 is used to control the flow of the liquid to ensure the accuracy and controllability of the filling process. The liquid level height detection device 4 is installed in the storage tank 1 to monitor the current height information of the liquid in the storage tank 1 in real time and feed back this information to the controller. The controller intelligently controls the working states of components such as the stirring device 2, the quantitative filling device 3, and the liquid supplement angle seat valve 36 according to the received liquid level information to achieve automated management.

[0039] Through the above technical solution, the controller can receive signals from sensors such as the liquid level height detection device 4, and according to the preset program and logic, precisely control the actuators such as the stirring device 2, the quantitative filling device 3, and the liquid supplement angle seat valve 36 to ensure the smooth progress of the entire processing process. The liquid supplement angle seat valve 36 ensures that the amount of liquid replenished into the quantitative filling device 3 always remains consistent within the specified opening and closing time through an electrical automatic control method.

[0040] When the quantitative filling device 3 drains the liquid in the storage tank 1 to the required amount, the connection relationship between the quantitative filling device 3 and the tank body can be released, and then the quantitative filling device 3 can be moved to above the electrolytic manganese tank at the specified position by the moving manipulator. At this time, the drain angle seat valve 33 is opened through an electrical automatic control method to empty the liquid in the quantitative filling device 3 and inject it into the electrolytic manganese tank. After a certain period of time, the liquid supplement angle seat valve 36 closes to prepare for the next filling.

[0041] After completing one filling, the liquid supplement angle seat valve 36 continues to open to replenish the liquid into the quantitative filling device 3, and so on in a cycle to achieve a continuous, efficient, and automated selenium dioxide liquid extraction process. The entire system, through a highly integrated and intelligent design, greatly improves the efficiency and accuracy of selenium dioxide treatment, reduces the complexity and risk of manual operation. At the same time, the stability and reliability of the system are also fully guaranteed.

[0042] In an embodiment provided by the present disclosure, the quantitative filling device 3 is located below the storage tank 1, and includes a tank body 31, a filling pipe 32, and a drain angle seat valve 33. One end of the filling pipe 32 communicates with the container, and the other end communicates with the tank body 31 through the drain angle seat valve 33; the drain angle seat valve 33 is communicatively connected to the controller.

[0043] The tank body 31 serves as a temporary storage and metering container for the liquid. The size and shape of the tank body 31 are usually determined according to the required filling volume. One end of the filling pipe 32 is connected to the container to ensure that the liquid can flow smoothly into the container; the other end is connected to the tank body 31 through the drain angle seat valve 33, so that under the control of the controller, the liquid can be accurately injected into the tank body 31 according to the preset amount.

[0044] The drain angle seat valve 33 controls the liquid flow between the filling pipe 32 and the tank body 31. The drain angle seat valve 33 is communicatively connected to the controller to receive the instructions of the controller to control the opening and closing of the valve. By accurately controlling the opening time and degree of the valve, it can ensure that the liquid volume filled each time maintains good accuracy, thus achieving the purpose of quantitative filling.

[0045] Specifically, the filling pipes 32 and the drain angle seat valves 33 are arranged in two groups and symmetrically arranged on both sides of the tank body 31. The two groups of filling pipes 32 can work simultaneously to quickly and evenly introduce the liquid from the storage tank 1 into the container. Compared with a single filling pipe 32, it can significantly shorten the filling time and improve the overall working efficiency.

[0046] In addition, different application scenarios may have different requirements for filling speed, accuracy, and stability. By adjusting the working parameters (such as flow rate, pressure, etc.) of the two groups of filling pipes 32, the quantitative filling device 3 can flexibly adapt to different application scenarios and meet various production requirements.

[0047] Furthermore, a blowing and emptying pipe 34 for blowing out the residual liquid in the filling pipe 32 is provided on the filling pipe 32, and the blowing and emptying pipe 34 is connected to an air pump.

[0048] After each filling, there may be a small amount of residual liquid in the filling pipe 32. If these residual liquids are not removed in time, it will affect the accuracy of the next filling. By blowing out the residual liquid through the blowing and emptying pipe 34, it can ensure the cleanliness and dryness inside the filling pipe 32, thereby improving the filling accuracy. By regularly blowing out the residual liquid, the cleanliness and smoothness of the equipment can be maintained, and its service life can be extended.

[0049] To ensure the smooth introduction of the liquid, the quantitative filling device 3 further includes an anti-overflow pipe 37. One end of the anti-overflow pipe 37 is connected to the tank body 31, and the other end extends upward, and the extension height is higher than the top surface height of the storage tank 1. When the liquid supplement angle seat valve 36 fails to close, the anti-overflow pipe 37 can serve as a safety barrier to effectively prevent the liquid from flowing out uncontrollably, protecting the safety of the surrounding environment and equipment.

[0050] One end of the overflow pipe 37 is connected to the tank body 31, and the other end extends upward and is higher than the top surface height of the water tank. In this way, during the normal filling process, even if the liquid in the tank body 31 rises due to certain reasons (such as overfilling or foam generated by stirring), it will not exceed the height of the overflow pipe 37 and overflow.

[0051] By adding the overflow pipe 37, the overall reliability of the quantitative filling device 3 is improved, the risk of production accidents caused by unexpected situations such as valve failures is reduced, and a strong guarantee is provided for the stability and continuity of the production process.

[0052] In the emergency situation of liquid overflow, the existence of the overflow pipe 37 can quickly isolate the problem within a controllable range and prevent the situation from further deteriorating. At the same time, it also provides a valuable time window for maintenance personnel to troubleshoot and solve faults such as valve failures. For operators, the design of the overflow pipe 37 reduces the risk of injury they may suffer from contacting the overflowing liquid.

[0053] In an embodiment provided by the present disclosure, a liquid adding port is provided on the storage tank 1; the automatic selenium dioxide adding device for the electrolytic manganese bath further includes a cover plate 5, one end of the cover plate 5 is rotatably connected to the top surface of the storage tank 1, and the other end is provided with a lock 6, and the lock 6 is lockably connected to the box body to be able to close and open the liquid adding port.

[0054] One end of the cover plate 5 and the top surface of the storage tank 1 adopt a rotatable connection method, such as hinge connection, so that the cover plate 5 can easily switch between the open and closed states, which can not only improve the operation convenience, but also reduce the wear and damage of components caused by frequent disassembly and assembly.

[0055] The other end of the cover plate 5 is provided with a lock 6, and the lock 6 can be firmly locked on the box body to ensure that when liquid adding is not required, the liquid adding port can be kept completely closed to prevent the cover plate 5 from loosening or falling off due to accidental collision or vibration, thereby ensuring the safe storage of the liquid in the storage tank 1.

[0056] A sealing gasket should be designed on the contact surface between the cover plate 5 and the top surface of the storage tank 1 or other sealing measures should be adopted to ensure that an effective sealing barrier can be formed when the cover plate 5 is closed, preventing impurities such as external air, dust or moisture from entering the inside of the storage tank 1 and affecting the purity and quality of the liquid.

[0057] In an embodiment provided by the present disclosure, the stirring device 2 includes: a positioning seat 21, fixedly connected to the storage tank 1; a driver 22, connected to the positioning seat 21; a transmission shaft 23, extending into the storage tank 1 and drivingly connected to the output shaft of the driver 22; and blades 24, fixedly connected to the transmission shaft 23.

[0058] The positioning seat 21 provides a stable support platform for components such as the drive 22 and the transmission shaft 23, ensuring the stability and reliability of the stirring device 2 during operation, and avoiding uneven stirring or equipment damage caused by shaking or loosening. The drive 22 can provide controllable and stable power output, and can adjust the rotation speed and torque according to the stirring requirements and process requirements to ensure that the stirring effect meets the expectations. The transmission shaft 23 rotates under the drive of the drive 22, thereby driving the blades 24 to stir, realizing effective stirring of the internal liquid, and making the components in the liquid be evenly mixed.

[0059] The drive 22 can be a power device such as an electric motor or a pneumatic motor, and a suitable type and specification can be selected according to specific requirements.

[0060] The material and structural design of the transmission shaft 23 should take into account the requirements of corrosion resistance, wear resistance and strength, so as to ensure its service life.

[0061] In addition, the shape, quantity and arrangement of the blades 24 can be optimized according to the characteristics of the stirred liquid and the process requirements. The material of the blades 24 should also have corrosion resistance and wear resistance to ensure the stability and reliability during long-term use.

[0062] Specifically, the blades 24 are arranged in at least two groups and are spaced along the axis of the transmission shaft.

[0063] Multiple groups of blades 24 can act on the liquid simultaneously, forming multiple stirring regions. The interaction between these regions can accelerate the flow and mixing of the liquid, thereby improving the stirring efficiency. Especially when dealing with high-viscosity or difficult-to-mix liquids, multiple groups of blades 24 can more effectively break the stratification and lumps in the liquid and achieve more uniform mixing.

[0064] The blades 24 spaced along the axis can generate stirring effects at different heights, so that the liquid in the entire storage tank 1 can be fully stirred. This three-dimensional stirring effect helps to eliminate the dead corners and unmixed regions in the liquid and further improves the uniformity and consistency of stirring.

[0065] During the stirring process, the liquid may generate reaction forces or impact forces, and multiple groups of blades 24 can disperse these forces, reducing the impact and wear on the transmission shaft 23 and the positioning seat 21, thereby extending the service life of the equipment.

[0066] In the present disclosure, the blades 24 are arranged in two groups spaced up and down.

[0067] Furthermore, the blades 24 are configured as three-blade impellers. The three-blade impellers can generate balanced stirring forces when rotating, so that the liquid is evenly mixed in the storage tank 1, which helps to reduce the dead corners and unmixed regions during the stirring process and improve the stirring efficiency and quality.

[0068] In addition, during the rotation process, the blade 24 can also push the liquid to form a circulating flow, promote the uniform distribution of each component in the liquid, reduce the vortex and turbulence phenomena of the liquid during the stirring process, and make the stirring process smoother and more controllable.

[0069] In the present disclosure, the liquid level height detection device 4 is configured as a liquid level gauge. A liquid level gauge is an instrument specifically used to measure the height of a liquid. It senses the position of the liquid surface directly or indirectly and converts this information into a signal that can be read or processed.

[0070] In other embodiments, the liquid level height detection device 4 can also be configured as a liquid level sensor, and the liquid level sensor is communicatively connected to the controller. Thus, accurate detection of the liquid level height in the storage tank 1 is achieved.

[0071] Furthermore, instruments such as radar and infrared ranging sensors can be added to more accurately detect the liquid level height. In this regard, those skilled in the art can flexibly select one or more of these according to actual usage requirements.

[0072] In the present disclosure, the controller is configured as a PLC logic controller.

[0073] Specifically, in the present utility model, the controller can also be configured as a Central Processing Unit (CPU). In other embodiments, the controller can also be one configured as a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), or a Field-Programmable Gate Array (FPGA).

[0074] In the present disclosure, the controller is communicatively connected to the stirring device 2, the quantitative filling device 3, the liquid replenishment angle seat valve 36, and the liquid level height detection device 4 through cables. In other embodiments, the controller can also be connected to the stirring device 2, the quantitative filling device 3, the liquid replenishment angle seat valve 36, and the liquid level height detection device 4 through wireless communication modules such as WiFi modules and ZigBee modules. In this regard, those skilled in the art can flexibly configure them under the technical concept of the present disclosure.

[0075] The present utility model is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present utility model. The above specific embodiments should not be construed as limiting the protection scope of the present utility model. The protection scope of the present utility model should be defined by the claims, and the description can be used to interpret the claims.
