Description

Technical Field

[0001] This utility model relates to the field of refined sodium tungstate production technology, and more specifically, to a mixing and clarification tank for refined sodium tungstate production. Background Technology

[0002] Sodium tungstate is a chemical substance, a colorless crystal or white crystalline powder that effloresces in dry air, loses its water of crystallization at 100°C, is soluble in water but insoluble in ethanol, has a relative density of 3.23–3.25, and a melting point of 698°C (anhydrous). The production of refined sodium tungstate requires extraction using a mixing and clarification tank. This tank consists of a mixing chamber and a clarification chamber, separated by an internal partition. The mixing chamber has a light phase inlet and a heavy phase channel on its two side plates, while the clarification chamber has a light phase outlet and a heavy phase outlet on its two side plates. The internal partition also has a mixing phase outlet.

[0003] In existing technologies, a stirring structure is usually installed in the mixing chamber of a mixing and clarification tank to achieve the purpose of stirring. However, existing mixing and clarification tanks lack a structure to prevent liquid splashing. During the stirring process, the liquid in the mixing chamber is prone to splashing due to shaking, which affects the cleanliness of the working environment, or splashes directly into the clarification chamber. This results in the heavy phase and light phase in the liquid in the mixing chamber not being fully contacted and mixed evenly, which greatly reduces the extraction and separation efficiency of the mixing and clarification tank. Therefore, a mixing and clarification tank for the production of refined sodium tungstate is needed to solve the above problems.

[0004] To address the above issues, application number 202122325714.8, entitled "A Mixing and Clarifying Tank for the Production of Refined Sodium Tungstate," describes a clarifying tank containing an anti-splash assembly. The clarifying tank has symmetrically arranged first locking holes on the left side of its inner wall, and symmetrically arranged second locking holes on one side of the first locking holes. The anti-splash assembly includes a first baffle and a second baffle, each with symmetrically arranged grooves. Locking blocks are slidably installed within these grooves, and the locking blocks are connected to the inner walls of the grooves via springs. The first and second baffles have notches at their closest points. The first baffle is connected to the clarifying tank via the locking blocks engaging the first locking holes, and the second baffle is connected to the clarifying tank via the locking blocks engaging the second locking holes. This invention prevents splashing of the extract liquid by using the first and second baffles, and the elastic restoring action of the springs allows the locking blocks to engage or disengage from the first and second locking holes, thus facilitating the assembly and disassembly of the anti-splash assembly.

[0005] Although the device has many beneficial effects, it still has the following problems: Although the device can shield the liquid splashed during the stirring process, avoid the extract from splashing due to agitation, and reduce the impact of the extract on the working environment, it is very inconvenient to clean the mixing chamber or sedimentation chamber in actual use. It requires personnel to disassemble multiple baffles, which undoubtedly increases the workload of the staff and causes great trouble in actual use.

[0006] Furthermore, when mixing sodium tungstate, this device only uses a stirring rod to stir and mix the sodium tungstate, which results in poor mixing efficiency and often requires a very long time, which undoubtedly brings a lot of inconvenience to actual use.

[0007] In view of this, we propose a mixing and clarification tank for the production of refined sodium tungstate. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The purpose of this invention is to provide a mixing and clarification tank for the production of refined sodium tungstate, so as to solve the problems mentioned in the background art.

[0010] 2. Technical Solution

[0011] A mixing and clarification tank for the production of refined sodium tungstate includes a sedimentation tank, a mixing tank on the side wall of the sedimentation tank, a fan-shaped nozzle on the inner wall of the sedimentation tank, a drain valve on the outer wall in front of the sedimentation tank, a lead screw motor on one side of the outer wall of the sedimentation tank, a lead screw connected to the output end of the lead screw motor, a movable plate sleeved on the outer wall of the lead screw, a fixed plate on the outer wall of the movable plate, a stirring assembly rotatably connected to the top of the fixed plate, the stirring assembly including gears, a water storage tank on the outer wall behind the sedimentation tank, water pumps on both sides of the outer wall of the water storage tank, and an ultrasonic generator and controller on the outer wall in front of the mixing tank.

[0012] Preferably, a water pump is fixedly sleeved inside the movable plate. The water pump is connected to an electromagnetic valve at its inlet end, and a connecting pipe is connected to the output end of the electromagnetic valve. The water pump is connected to a drain pipe at its outlet end, and the drain pipe extends to the outer wall of the other side of the movable plate.

[0013] Preferably, a limiting plate is provided on the outer rear wall of the movable plate, and a rubber plate is provided on the outer wall of the movable plate, the rubber plate being in contact with the inner wall of the sedimentation tank.

[0014] Preferably, multiple water pumps are connected to water delivery pipes at their output ends, and the ends of the multiple water delivery pipes are rotatably connected to the top of the transmission gear and the input end of the fan-shaped nozzle.

[0015] Preferably, a water spray cylinder is provided at the bottom of the transmission gear, and multiple water spray holes are opened on the outer circumference of the water spray cylinder. A transmission rod is provided at the bottom of the water spray cylinder, and a stirring rod is fixedly connected to the outer circumference of the transmission rod.

[0016] Preferably, an installation groove is provided at the bottom of the inner cavity of the mixing tank, and an ultrasonic vibration plate is installed inside the installation groove. The ultrasonic vibration plate is electrically connected to the ultrasonic generator.

[0017] Preferably, the top of the fixing plate is further provided with a connecting frame, the top of the connecting frame is provided with a drive motor, and the output end of the drive motor is connected to a gear that meshes with the transmission gear.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of this utility model are as follows: When it is necessary to clean the inside of the mixing tank and the stirring rod, the second water pump on one side of the water storage tank can be started first, and then the stirring component can be rotated by the drive motor. The second water pump on one side will transport the water source inside the water storage tank to the spray nozzle, so that the cleaning water can be sprayed and rinsed on the inner wall of the mixing tank by rotating spray. Then, the ultrasonic vibration plate can be used in conjunction with the cleaning water to perform ultrasonic cleaning on the inside of the mixing tank. When cleaning the sedimentation tank, the solenoid valve can be opened, and then the cleaning water can be transported to the sedimentation tank on the other side of the moving plate by the action of the first water pump. Then, the moving plate can be moved horizontally under the drive of the screw motor, and the impurities on the inner wall of the sedimentation tank can be cleaned in conjunction with the action of its rubber plate. When the screw motor drives the moving plate to the limit position, the fan-shaped nozzle can be controlled to tilt and spray water to rinse the inside of the sedimentation tank. The limit plate reduces the splashing of water when the water source is rinsed, and the impurities washed down can be better discharged through the drain valve, making the cleaning of the mixing tank and sedimentation tank more convenient and more practical.

[0020] When mixing sodium tungstate, a stirring rod can be used for initial stirring. Simultaneously, an ultrasonic vibrating plate can be used to radiate powerful ultrasonic energy into the surrounding liquid medium via high-frequency vibration. As these ultrasonic waves propagate through the liquid, they produce a series of complex physical effects. For example, the cavitation effect of the ultrasound creates numerous tiny bubbles in the liquid. These bubbles rapidly expand and burst within a very short time, generating strong microjets and localized high-temperature, high-pressure regions. These microjets can overcome the existing concentration gradient and diffusion resistance in the solution, allowing different components to penetrate and blend more quickly, further enhancing the turbulence of the liquid. This makes the mixing flow field generated by the rotation of the stirring rod more chaotic and complex. This not only allows materials in the central area of ​​the mixing tank to exchange positions with materials in the edge areas more quickly, but also effectively eliminates mixing dead zones that are prone to occur in traditional stirring. Through the synergistic cooperation of ultrasonic vibration and stirring rod rotation, the mixing efficiency of sodium tungstate is further improved, significantly shortening the mixing process that originally required a long time, effectively enhancing its stirring efficiency.

[0037] Furthermore, a limiting plate 230 is provided on the rear outer wall of the movable plate 200, and a rubber plate 210 is provided on the outer wall of the movable plate 200. The rubber plate 210 is in contact with the inner wall of the sedimentation tank 100, which facilitates cleaning of the inner wall of the sedimentation tank 100 during the movement of the movable plate 230.

[0038] Furthermore, the output ends of multiple water pumps 2310 are respectively connected to water delivery pipes, and the ends of the multiple water delivery pipes are respectively rotatably connected to the top of the transmission gear 260 and the input end of the fan-shaped nozzle 130.

[0039] In some embodiments, the end of one side of the water supply pipe extends into the interior of the water spray cylinder 270 to facilitate water delivery without affecting its rotation.

The ultrasonic vibration plate 440 is electrically connected to the ultrasonic generator 410.

[0042] It is worth noting that a connecting frame 250 is also provided on the top of the fixing plate 240, and a drive motor 251 is provided on the top of the connecting frame 250. The output end of the drive motor 251 is connected to a gear 252 that meshes with the transmission gear 260, so that the drive motor 251 can drive the transmission gear 260 to rotate.

[0043] In some embodiments: the device can be powered by an external conventional power source, and the device can be controlled by the controller 420.

[0044] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0045] Working principle: When cleaning the inside of the mixing tank 400 and the stirring rod 290 is required, the water pump 310 on one side of the water storage tank 300 can be started first. Then, the stirring assembly is rotated by the drive motor 251, causing the water pump 310 to deliver water from the water storage tank 300 to the spray nozzle 270. This allows the cleaning water to be sprayed and rinsed onto the inner wall of the mixing tank 400 through a rotating spray. Afterwards, the ultrasonic vibration plate 440 can be used in conjunction with the cleaning water to perform ultrasonic cleaning on the inside of the mixing tank 400. When cleaning the sedimentation tank 100, the solenoid valve 2 can be opened. 21. Then, the water pump 220 transports the cleaning water to the sedimentation tank 100 on the other side of the moving plate 200. Driven by the screw motor 120, the moving plate 200 moves horizontally, and the rubber plate 210 cleans the impurities on the inner wall of the sedimentation tank 100. When the screw motor 120 moves the moving plate 200 to its limit position, the fan-shaped nozzles 130 can be controlled to tilt and spray water into the sedimentation tank 100. The limiting plate 230 reduces water splashing during the rinsing process and better discharges the washed-down impurities through the drain valve 110, thus facilitating the mixing of the sedimentation tank. The 400 and 100 sedimentation tanks are easier to clean and more practical. When mixing sodium tungstate, the stirring rod 290 can be used for initial stirring. Simultaneously, the ultrasonic vibrating plate 440 can be used to radiate powerful ultrasonic energy into the surrounding liquid medium via high-frequency vibration. As these ultrasonic waves propagate in the liquid, they produce a series of complex physical effects. For example, the cavitation effect of the ultrasonic waves forms a large number of tiny bubbles in the liquid. These bubbles rapidly expand and burst in a very short time, generating strong microjets and localized high-temperature and high-pressure areas. These microjets can break through the original... The inherent concentration gradient and diffusion resistance allow substances of different components to penetrate and blend more quickly, further enhancing the turbulence of the liquid. This makes the mixing flow field generated by the rotation of the stirring rod 290 more chaotic and complex. This not only allows the material in the central area of ​​the mixing tank to exchange positions with the material in the edge area more quickly, but also effectively eliminates the mixing dead zones that are easy to occur in traditional stirring. Through the synergistic cooperation of ultrasonic vibration and the rotation of the stirring rod 290, the mixing efficiency of sodium tungstate is further improved. The mixing process that originally required a long time to complete is greatly shortened, effectively improving its stirring efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
