Description

Technical Field

[0001] This invention relates to the field of indium electrolyte equipment and preparation technology, specifically to an indium electrolyte preparation and purification equipment for quantitatively adding raw materials. Background Technology

[0002] Indium electrolyte is a solution used for electrochemical deposition or electroplating of indium, a rare metal commonly used in electronics, optics, and materials science. Indium electrolyte is usually composed of solutions containing indium salts, such as indium chloride (InCl3) and indium salts (In(NO3)3). Indium electrolyte is an important component required in the indium electrolytic purification process, and it is made by dissolving indium or its compounds in acid.

[0003] However, the existing technology still has the following drawbacks in practical applications:

[0004] In the preparation and purification of indium electrolyte, enamel basins or quartz vessels are mostly used as electrolytic containers and heated on an electric furnace. This process can lead to the following problems: First, enamel basins can be corroded by acid, contaminating the electrolyte. Second, due to external heating, quartz vessels are prone to uneven heating and breakage, resulting in electrolyte loss. Third, if the heated container breaks on the electric furnace, electrolyte leakage can cause short circuits in the furnace and burns to personnel. In addition, uneven addition of indium raw materials can prevent indium from dissolving quickly in the electrolyte, increasing the preparation time and reducing the quality of the purified indium electrolyte.

[0005] Therefore, in view of this, the present invention proposes an indium electrolyte preparation and purification device for quantitatively adding raw materials to make up for and improve the deficiencies of the prior art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an indium electrolyte preparation and purification device for quantitatively adding raw materials, thereby resolving the technical issues raised in the background section.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an indium electrolyte preparation and purification device for quantitatively adding raw materials, comprising a protective box and a reaction vessel, wherein the reaction vessel is disposed inside the protective box, a lifting component is disposed on one outer wall of the protective box, a fixed support rod is hinged to one side of the outer wall of the lifting component, a motor is mounted on the top of the fixed support rod away from the lifting component, a stirring rod is fixedly connected to the output shaft end of the motor through the inside of the fixed support rod, a quantitative feeding mechanism is disposed on the outer wall of the fixed support rod near the motor, a fixed clamping assembly is disposed on the inner wall of the bottom of the protective box, and an auxiliary limiting mechanism is disposed on the inner wall of the top of the protective box.

[0008] Furthermore, the quantitative feeding mechanism includes a feeding container fixedly connected to the outer wall of the fixed support rod, a connecting section fixedly connected to the top of the stirring rod, a rotating disk rotatably connected through the bottom inner wall of the feeding container, a connecting support rod rotatably connected to the outer wall of the connecting section, the end of the connecting support rod away from the connecting section being hinged to the bottom of the rotating disk on the side away from the center of rotation, a flow guide frustum fixedly connected to the top of the rotating disk and above the bottom inner wall of the feeding container, and multiple discharge ports evenly opened at the bottom of the feeding container.

[0009] Furthermore, there are two of each of the feeding container, rotating disk, connecting support rod, and flow guiding frustum, all symmetrically arranged around the fixed support rod as the central axis, and each of the two flow guiding frustums has a material guiding groove on its bottom outer wall.

[0010] Furthermore, the outer wall at the bottom of the protective box is provided with a discharge channel, and the outer wall at the bottom of the reaction vessel is connected to a drain valve.

[0011] Furthermore, the fixing clamping assembly includes four support crossbars fixedly connected to the inner wall of the bottom of the protective box in a rectangular distribution. Each of the four support crossbars has a stop block rotatably connected to its inner wall at the middle. The reaction container is placed on the top of the four support crossbars. Each of the four stop blocks has a support spring fixedly connected to its bottom on the side away from the reaction container. Each of the four support springs has its end away from the support crossbar fixedly connected to the inner wall of the bottom of the protective box.

[0012] Furthermore, the four baffles are all Y-shaped, and all four baffles abut against the outer wall of the bottom of the reaction vessel.

[0013] Furthermore, the auxiliary limiting mechanism includes a fixed frame fixedly connected to the inner wall of the top of the protective box. A cylinder is slidably connected through the inner wall of the fixed frame. A limiting block is fixedly connected to the end of the cylinder away from the fixed frame. An elongated groove is formed on the inner wall of the side of the limiting block away from the fixed frame. Three guide wheels are rotatably connected to the inner wall of the elongated groove in an up-down distribution. A second spring is fixedly connected to the outer wall of the limiting block near the fixed frame. The end of the second spring away from the limiting block is fixedly connected to the outer wall of the fixed frame.

[0014] Furthermore, the fixing frame, cylinder, limiting block, and second spring are evenly arranged in three on the inner wall of the top of the protective box.

[0015] Furthermore, the fixed frame is provided with an auxiliary deceleration assembly, which includes a bracket fixedly connected to the end of the cylinder away from the limiting block. A first buffer air bag is fixedly connected to the inner wall of the bracket. A second buffer air bag is symmetrically fixedly connected between the guide wheel and the side wall of the long groove. An air pipe connects the two second buffer air bags to the first buffer air bag.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) By setting up a quantitative feeding mechanism, when the rotating disk carries the guide platen to rotate inside the feeding container, when the guide groove on the outer wall of the guide platen is aligned with the discharge port, the indium raw material stored inside the feeding container will be discharged through the discharge port and fall into the electrolyte inside the reaction container. Since the guide platen rotates continuously, there is a time interval between the alignment of the guide groove and the discharge port. This gap period can be used to achieve the purpose of quantitatively adding indium raw material. Combined with the stirring action of the stirring rod, the purpose of fully dissolving indium raw material and electrolyte can be achieved, which helps to improve the efficiency of indium electrolyte preparation and purification. At the same time, the reaction container with built-in heating function adds indium raw material while stirring, avoiding waste of indium raw material, making the mixing more uniform, improving the quality of indium electrolyte preparation and purification, and shortening the preparation time.

[0018] (2) By setting an auxiliary limiting mechanism, when the No. 2 buffer gas bag is inflated from a deflated state to an expanded state, the gap between the guide wheel and the long groove is reduced, thereby increasing the rotation resistance of the guide wheel and slowing down the rotation of the guide wheel, preventing the guide wheel from rotating too fast. When the guide wheel contacts the surface of the reaction container, it can slow down the descent speed of the reaction container, preventing the reaction container from falling too fast and causing it to collide directly with the inner wall of the bottom of the protective box and be damaged. This effectively protects the reaction container and improves its service life.

[0019] (3) By setting a fixed clamping component, when the block is squeezed by the outer wall of the reaction container, it will flip over and squeeze the support spring at the same time. After the reaction container is completely placed in place, the block will reset under the rebound of the support spring and play the role of clamping and fixing the reaction container. With the limit block, it helps to improve the stability of the reaction container during placement inside the protective box, avoids shaking during the preparation and purification of indium electrolyte, which could cause the electrolyte to spill out and cause safety hazards such as burns to the staff. It helps to improve the safety of the reaction container during use. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Embodiments of the present invention

[0031] The reaction vessel 2 used in this technical solution is a feature of existing technology, which has its own heating function, as is known to those skilled in the art, and therefore its specific working principle is not described in detail.

[0032] Please refer to Figures 1 to 4 As shown, an indium electrolyte preparation and purification device for quantitatively adding raw materials includes a protective box 1 and a reaction vessel 2. The reaction vessel 2 is located inside the protective box 1. A lifting component 3 is provided on one outer wall of the protective box 1. A fixed support rod 301 is hinged to one side of the outer wall of the lifting component 3. A motor 302 is installed at the top of the end of the fixed support rod 301 away from the lifting component 3. A stirring rod 303 is fixedly connected to the output shaft end of the motor 302 through the inside of the fixed support rod 301. A quantitative feeding mechanism is provided on the outer wall of the end of the fixed support rod 301 near the motor 302.

[0033] The quantitative feeding mechanism includes a feeding container 401 fixedly connected to the outer wall of a fixed support rod 301, a connecting section 402 fixedly connected to the top of a stirring rod 303, a rotating disk 403 rotatably connected through the bottom inner wall of the feeding container 401, a connecting support rod 404 rotatably connected to the outer wall of the connecting section 402, and a connecting support rod 404 hinged at the bottom of the rotating disk 403 away from the center of rotation at one end of the connecting support rod 404. A flow guide frustum 405 is fixedly connected to the top of the rotating disk 403 and above the bottom inner wall of the feeding container 401. Multiple discharge ports 406 are evenly provided at the bottom of the feeding container 401. The feeding container 401, rotating disk 403, connecting support rod 404, and flow guide frustum 405 are symmetrically arranged in two units about the fixed support rod 301 as the central axis. The bottom outer walls of the two flow guide frustums 405 are provided with material guide grooves.

[0034] The fixed support rod 301 is adjusted to be directly above the reaction vessel 2. Then, the lifting component 3 is activated via a button on the control panel, causing the fixed support rod 301 to descend along with the stirring rod 303, allowing the stirring rod 303 to extend into the reaction vessel 2. The required amount of indium raw material is then added to the filling container 401. Simultaneously, the motor 302 is activated via a button on the control panel, causing the output shaft of the motor 302 to rotate, carrying the stirring rod 303 and the connecting section 402. When the connecting section 402 rotates one revolution with the stirring rod 303, the connecting support rod 404, rotatably connected to the outer wall of the connecting section 402, will rotate the rotating disk 403. The rotating disk 403 then causes the guide frustum 405 to rotate inside the filling container 401, thus... When the guide channel on the outer wall of the flow-guiding frustum 405 is aligned with the discharge port 406, the indium raw material stored inside the feeding container 401 is discharged through the discharge port 406 and falls into the electrolyte inside the reaction container 2. As the flow-guiding frustum 405 rotates continuously, there is a time interval between the alignment of the guide channel and the discharge port 406. This gap period can be used to achieve the purpose of quantitatively adding indium raw material. Combined with the stirring action of the stirring rod 303, the indium raw material and the electrolyte are fully dissolved, which helps to improve the efficiency of indium electrolyte preparation and purification. At the same time, the reaction container 2 with its own heating function adds indium raw material while stirring, avoiding waste of indium raw material, making the mixing more uniform, improving the quality of indium electrolyte preparation and purification, and shortening the preparation time.

[0035] Please refer to Figure 3 Preferably, the guide frustum 405 has a shape that is narrower at the top and wider at the bottom, and the surface of the guide frustum 405 is set with an inclined surface. When the indium raw material is placed in the feeding container 401, the guide frustum 405 can help the indium raw material to slide down quickly and fall into the interior of the reaction vessel 2 through the guide groove and the discharge port 406, which facilitates the discharge of the indium raw material.

[0036] Please refer to Figure 1 , Figure 2 as well as Figure 5 As shown, preferably, the bottom outer wall of the protective box 1 is provided with a discharge channel 501, and the bottom outer wall of the reaction vessel 2 is connected to a drain valve 502.

[0037] Please refer to Figure 2 , Figure 5 as well as Figure 6 As shown, preferably, a fixing clamping assembly is provided on the bottom inner wall of the protective box 1;

[0038] The fixed clamping assembly includes four support crossbars 601 that are fixedly connected to the bottom inner wall of the protective box 1 in a rectangular arrangement. Each of the four support crossbars 601 has a stop block 602 rotatably connected to the inner wall of the middle of each of the four support crossbars 601. The reaction container 2 is placed on top of the four support crossbars 601. Each of the four stop blocks 602 has a support spring 603 fixedly connected to the bottom of the side away from the reaction container 2. Each of the four support springs 603 has a Y-shaped outline and abuts against the bottom outer wall of the reaction container 2.

[0039] When the reaction container 2 descends inside the protective box 1, its bottom first lands on the surface of the support crossbar 601. At the same time, the outer wall of the bottom end of the reaction container 2 contacts the stop block 602 and exerts a squeezing force on the stop block 602 away from the reaction container 2, causing the stop block 602 to flip over. This also squeezes the support spring 603. After the reaction container 2 is fully placed in place, the stop block 602 returns to its original position under the rebound action of the support spring 603, thus clamping and fixing the reaction container 2. Together with the limiting block 703, this helps to improve the stability of the reaction container 2 during placement inside the protective box 1, preventing shaking and electrolyte spillage, thereby improving the safety of the reaction container 2 during use.

[0040] Please refer to Figure 6 Preferably, when the reaction container 2 is placed inside the protective box 1, the bottom of the reaction container 2 rests on the top of the support crossbar 601. The Y-shaped stop 602 facilitates contact with the outer wall of the bottom end of the reaction container 2. At the same time, the outer wall of the bottom end of the reaction container 2 exerts an outward squeezing force on the Y-shaped stop 602, causing the stop 602 to flip away from the reaction container 2 and simultaneously squeezing the support spring 603. Under the rebound action of the support spring 603, the stop 602 is reset, and the Y-shaped stop 602 re-contacts the outer wall of the bottom end of the reaction container 2, thereby clamping and fixing the reaction container 2.

[0041] Please refer to Figure 1 , Figure 2 , Figure 5as well as Figure 7 , Figure 8 As shown, preferably, an auxiliary limiting mechanism is provided on the inner wall of the top of the protective box 1;

[0042] The auxiliary limiting mechanism includes a fixed frame 701 fixedly connected to the inner wall of the top of the protective box 1. A cylinder 702 is slidably connected through the inner wall of the fixed frame 701. A limiting block 703 is fixedly connected to the end of the cylinder 702 away from the fixed frame 701. An elongated groove 704 is formed on the inner wall of the side of the limiting block 703 away from the fixed frame 701. Three guide wheels 705 are rotatably connected to the inner wall of the elongated groove 704 in a vertically distributed manner. A second spring 706 is fixedly connected to the outer wall of the side of the limiting block 703 near the fixed frame 701. The end of the second spring 706 away from the limiting block 703 is fixedly connected to the fixed frame 701. The outer wall of the frame 701, the fixed frame 701, the cylinder 702, the limiting block 703 and the second spring 706 are evenly arranged on the inner wall of the top of the protective box 1. The fixed frame 701 is equipped with an auxiliary deceleration assembly. The auxiliary deceleration assembly includes a bracket 801 fixedly connected to the end of the cylinder 702 away from the limiting block 703. The inner wall of the bracket 801 is fixedly connected to the first buffer air bag 802. The guide wheel 705 and the side wall of the long groove 704 are symmetrically fixedly connected to the second buffer air bag 803. The two second buffer air bags 803 and the first buffer air bag 802 are connected by an air pipe 804.

[0043] In this process, by vertically placing the reaction vessel 2 into the protective box 1, the outer wall of the bottom of the reaction vessel 2 first contacts the limiting block 703 and the guide wheel 705. The guide wheel 705 is rotatably connected to the inner wall of the long groove 704, thus limiting and guiding the reaction vessel 2, ensuring that the reaction vessel 2 remains in a vertical state and is successfully placed inside the protective box 1. As the reaction vessel 2 descends, the limiting block 703, after being squeezed by the outer wall of the reaction vessel 2, pushes the cylinder 702 to slide towards the side of the fixed frame 701, while simultaneously acting on the second spring 706. As the cylinder 702 slides, the support 801 gradually pushes the first buffer air bag 802 towards the side wall of the protective box 1. When the side of the first buffer air bag 802 away from the support 801 contacts the side wall of the protective box 1, the compression of the first buffer air bag 802 by the support 801 causes gas to be generated after compression. The gas is introduced into the second buffer air bag 803 through the air pipe 804. Since the second buffer air bag 803 is located between the side wall of the long groove 704 and the outer wall of the guide wheel 705, the second buffer air bag 803 expands from a deflated state. At this time, the gap between the guide wheel 705 and the long groove 704 is reduced, thereby increasing the rotational resistance of the guide wheel 705. This slows down the rotation of the guide wheel 705, preventing it from rotating too fast. When the guide wheel 705 contacts the surface of the reaction vessel 2, it also slows down the descent speed of the reaction vessel 2, preventing it from colliding directly with the inner wall of the bottom of the protective box 1 and causing damage. This effectively protects the reaction vessel 2 and extends its service life. In addition, after the reaction vessel 2 is placed in position, in the second... Under the rebound action of the spring 706, the cylinder 702, along with the limiting block 703, is reset, and the limiting block 703 and the guide wheel 705 are in close contact with the outer wall of the reaction vessel 2, thereby achieving a fixing effect. The first buffer gas bag 802 is reset without being squeezed by the support 801 and the top side wall of the protective box 1. At the same time, when the first buffer gas bag 802 returns to its initial shape, under the action of negative pressure, the gas inside the second buffer gas bag 803 is transported to the first buffer gas bag 802 through the gas pipe 804, thus facilitating the next use of the first buffer gas bag 802 and the second buffer gas bag 803.

[0044] Please refer to Figure 8Preferably, the limiting block 703 has an arc-shaped profile on the side near the reaction vessel 2, which facilitates contact between the reaction vessel 2 and the limiting block 703. This allows for smooth operation during the placement and removal of the reaction vessel 2 inside the protective box 1. In addition, the bracket 801 has a C-shaped profile, which allows the bracket 801 to fit the profile of the first buffer gas bag 802. This facilitates the compression of the first buffer gas bag 802 by the top side wall of the fixing frame 701. The gas generated by the compression of the first buffer gas bag 802 is then introduced into the second buffer gas bag 803 through the air pipe 804, causing the second buffer gas bag 803 to expand. This reduces the rotation speed of the guide wheel 705, which is beneficial for the reaction vessel 2 to descend slowly inside the protective box 1.

[0045] The following are the complete usage steps and working principle of the above embodiments:

[0046] When the device is in use, the reaction container 2 is placed inside the protective box 1. When the reaction container 2 is damaged, the protective box 1 can protect and isolate the reaction container 2, thereby preventing the electrolyte inside the reaction container 2 from flowing out and causing safety accidents such as electrolyte burns to personnel. This reduces the safety hazards to personnel during the preparation and purification of indium.

[0047] Since the fixed support rod 301 is hinged to the lifting component 3, and the lifting component 3 is activated via the operation button on the control panel, the lifting component 3 raises the fixed support rod 301 to a suitable height, so that the bottom of the stirring rod 303 is positioned above the top of the reaction vessel 2. Then, the operator uses a tool to pull the fixed support rod 301 towards one side of the lifting component 3, causing the fixed support rod 301 to rotate 90 degrees, thus creating an opening in the protective box 1 for subsequent placement of the reaction vessel 2. By vertically placing the reaction vessel 2 inside the protective box 1, the outer wall of the bottom of the reaction vessel 2 will first contact the limiting block 703 and the guide wheel 705, and the guide wheel 705 will rotatably connect to the inner wall of the long groove 704, thereby allowing for the reaction... Container 2 serves as a limiting guide, ensuring that the reaction container 2 remains vertical and is smoothly placed inside the protective box 1. As the reaction container 2 descends, the limiting block 703, under pressure from the outer wall of the reaction container 2, pushes the cylinder 702 towards the side of the fixing frame 701, simultaneously compressing the second spring 706. As the cylinder 702 slides, the support 801 gradually pushes the first buffer gas bag 802 towards the side wall of the protective box 1. When the side of the first buffer gas bag 802 furthest from the support 801 contacts the side wall of the protective box 1, the compression of the first buffer gas bag 802 by the support 801 causes gas to be generated. Gas is introduced into the second buffer gas bag 803 through the gas pipe 804. Since the second buffer gas bag 803 is located between the side wall of the long groove 704 and the outer wall of the guide wheel 705, when the second buffer gas bag 803 expands from a deflated state, the gap between the guide wheel 705 and the long groove 704 decreases. This increases the rotational resistance of the guide wheel 705, slowing its rotation and preventing it from rotating too quickly. When the guide wheel 705 contacts the surface of the reaction vessel 2, it also slows down the descent of the reaction vessel 2, preventing it from colliding directly with the inner wall of the bottom of the protective box 1 and causing damage. This effectively protects the reaction vessel 2. The reaction vessel 2 extends its service life. Furthermore, after the reaction vessel 2 is placed in position, the return action of the second spring 706 causes the cylinder 702, along with the limiting block 703, to reset, ensuring close contact between the limiting block 703, guide wheel 705, and the outer wall of the reaction vessel 2, thus achieving a fixing effect. The first buffer gas bag 802 resets without being squeezed by the support 801 and the top side wall of the protective box 1. Simultaneously, when the first buffer gas bag 802 returns to its initial shape, under negative pressure, the gas inside the second buffer gas bag 803 is transported to the first buffer gas bag 802 via the gas pipe 804, facilitating the next use of both the first and second buffer gas bags 802.

[0048] When the reaction container 2 descends inside the protective box 1, its bottom first lands on the surface of the support crossbar 601. At the same time, the outer wall of the bottom end of the reaction container 2 contacts the stop block 602 and exerts a squeezing force on the stop block 602 away from the reaction container 2, causing the stop block 602 to flip over. This also compresses the support spring 603. After the reaction container 2 is fully placed in position, the stop block 602 returns to its original position under the rebound action of the support spring 603, thus clamping and fixing the reaction container 2. Together with the limiting block 703, this helps to improve the stability of the reaction container 2 during placement inside the protective box 1, avoiding shaking that could cause electrolyte spillage and pose a safety hazard such as burns to workers. This improves the safety of the reaction container 2 during use.

[0049] By setting up the discharge channel 501, it is convenient for staff to connect the pipe to the drain valve 502, thereby achieving the purpose of discharging the electrolyte inside the reaction vessel 2;

[0050] After the reaction vessel 2 is successfully placed inside the protective box 1, the operator uses tools to pull the fixed support rod 301 near the lifting component 3 back to directly above the reaction vessel 2. The lifting component 3 is then activated via a button on the control panel, causing the fixed support rod 301 to descend along with the stirring rod 303, allowing the stirring rod 303 to extend into the reaction vessel 2. The required amount of indium raw material is then added to the filling container 401. Simultaneously, the motor 302 is activated via a button on the control panel, causing the output shaft of the motor 302 to rotate, carrying the stirring rod 303 and the connecting section 402. When the connecting section 402 rotates once with the stirring rod 303, the connecting support rod 404, which is rotatably connected to the outer wall of the connecting section 402, rotates the rotating disk 403, which in turn rotates the guide plate. The indium material stored inside the feeding container 401 rotates. When the guide channel on the outer wall of the guide frustum 405 aligns with the discharge port 406, the indium material stored inside the feeding container 401 is discharged through the discharge port 406 and falls into the electrolyte inside the reaction vessel 2. Because the guide frustum 405 rotates continuously, there is a time interval between the alignment of the guide channel and the discharge port 406. This interval can be used to quantitatively add indium material. Combined with the stirring action of the stirring rod 303, the indium material and the electrolyte are fully dissolved, which helps to improve the efficiency of indium electrolyte preparation and purification. At the same time, the reaction vessel 2 with its own heating function adds indium material while stirring, avoiding waste of indium material, making the mixing more uniform, improving the quality of indium electrolyte preparation and purification, and shortening the preparation time.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
