Description

Technical Field

[0001] This invention relates to the technical field of hydrogen peroxide preparation. More specifically, this invention relates to an apparatus for preparing high-purity hydrogen peroxide. Background Technology

[0002] Ultrapure hydrogen peroxide is a crucial microelectronic chemical reagent, typically purified from industrial-grade hydrogen peroxide. Current technology for producing ultrapure hydrogen peroxide involves mixing the industrial-grade hydrogen peroxide raw material with 0.5%–2% modified activated carbon by weight to remove organic carbon. However, due to the relatively small proportion of modified activated carbon powder, it floats on the surface when added to the hydrogen peroxide solution. Direct stirring causes the powder to adhere to the stirring rod or container wall above the liquid surface, resulting in insufficient mixing. Consequently, the amount of modified activated carbon mixed into the solution is far less than the predetermined value, severely impacting the organic carbon removal efficiency. Summary of the Invention

[0003] The present invention provides an apparatus for preparing high-purity hydrogen peroxide, the purpose of which is to overcome the shortcomings of existing equipment that result in insufficient mixing when stirring hydrogen peroxide solution and modified activated carbon powder.

[0008] Further explanation: It also includes a toggle assembly; the toggle assembly is connected to the second round rod; the toggle assembly includes a second connecting block, a second elastic telescopic rod, a third round rod, a lever, and a linkage unit; the second connecting block is fixedly connected to the inner side of the second round rod; the second elastic telescopic rod is fixedly connected to the lower side of the second connecting block; the third round rod is fixedly connected to the telescopic end of the second elastic telescopic rod; the third round rod is slidably connected to the second round rod; several levers are threaded through the third round rod; the linkage unit is connected to the second round rod; the linkage unit is used to drive the third round rod to move downward.

While the stirring rod stirs the hydrogen peroxide raw material solution, the modified activated carbon powder inside it gradually flows into the hydrogen peroxide raw material solution for thorough mixing, thus avoiding the problem of insufficient mixing caused by activated carbon powder adhering to the stirring rod or container side wall above the liquid surface in the prior art.

[0016] Meanwhile, the modified activated carbon powder is gradually filled into the first cavity from bottom to top by the second round rod, which effectively avoids the problem of clogging when the first cavity is wet. At the same time, the second round rod is also used to link the lever to move up and down, so that the lever moves the modified activated carbon powder in the second cavity and makes it fall smoothly, which effectively avoids the problem of the modified activated carbon powder getting stuck in the second cavity and unable to fall automatically. At the same time, the modified activated carbon powder is guided out of the second cavity by the first guide block, which prevents the modified activated carbon powder from remaining at the bottom of the second cavity.

[0017] During the stirring process, the third guide block directs more solution into the first opening and the first cavity, thereby quickly flushing out the modified activated carbon powder in the first cavity, which helps to improve mixing efficiency. At the same time, by making the width of the third guide block increase from top to bottom, more solution is guided into the lower part of the first cavity, which evenly flushes out the modified activated carbon powder in various positions of the first cavity, which helps to improve mixing uniformity and further improve mixing efficiency. Meanwhile, the second guide block directs the solution towards the inner wall of the long rod, so that the solution impacts the inner wall of the long rod and prevents the modified activated carbon powder from adhering and remaining on the inner wall of the long rod.

Detailed Implementation

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Implementation Plan 1

[0031] An apparatus for the preparation of high-purity hydrogen peroxide, such as Figure 1-5As shown, the assembly includes a support frame 1, a first cylinder 2, and a cylinder cover 3; the first cylinder 2 is bolted to the support frame 1; the cylinder cover 3 is bolted to the upper side of the first cylinder 2; it also includes a long rod 4, stirring blades 5, first elastic telescopic rods 6, movable plates 7, sealing rings 8, first round rods 9, gravity balls 10, a conveying assembly, and a rotating assembly; the long rod 4 is rotatably connected to the cylinder cover 3; two stirring blades 5 are welded to the long rod 4; a first cavity 91 is opened inside the long rod 4; two first openings 92 are opened inside the long rod 4, and the first openings 92 communicate with the first cavity 91; four first elastic telescopic rods 6 are bolted to the long rod 4; two movable plates 7 are provided inside the long rod 4, and the movable plates 7 are located inside the corresponding first openings 92; both movable plates 7 are connected to the corresponding... The first elastic telescopic rod 6 is fixedly connected to the telescopic end; a sealing ring 8 is fixedly connected to the outer side of each of the two movable plates 7, and the sealing ring 8 slides on the long rod 4; a first round rod 9 is welded to the middle of each of the two movable plates 7; a gravity ball 10 is welded to each of the two first round rods 9, and the gravity ball 10 is made of alloy material; the long rod 4 drives the stirring blade 5 to rotate, stirring the solution, and the long rod 4 is also used to move the modified activated carbon powder into the solution. During the rotation of the long rod 4, the modified activated carbon powder inside it is evenly diffused into the solution; a conveying assembly is connected to the first cylinder 2; the conveying assembly is used to convey the raw material solution into the first cylinder 2, and also to transfer the stirred solution out of the first cylinder 2; a rotating assembly is connected to the cylinder cover 3; the rotating assembly is used to drive the long rod 4.

[0032] The conveying assembly includes a first pipe 201, a first solenoid valve 202, a second pipe 203, and a second solenoid valve 204; the first pipe 201 is connected to the upper side of the first cylinder 2 and flanged; the first solenoid valve 202 is installed on the first pipe 201; the second pipe 203 is connected to the bottom of the first cylinder 2 and flanged; the second solenoid valve 204 is installed on the second pipe 203.

[0033] The rotating assembly includes a motor 205, a first spur gear 206, and a second spur gear 207; the motor 205 is bolted to the cylinder cover 3; the output shaft of the motor 205 is fixedly connected to the first spur gear 206; the second spur gear 207 is fixedly connected to the long rod 4; the first spur gear 206 and the second spur gear 207 mesh with each other.

[0034] First, the external feed pipe is manually connected to the first pipe 201, and the external discharge pipe is connected to the second pipe 203. Modified activated carbon powder is poured into the first cavity 91 of the long rod 4. The first solenoid valve 202 is opened, and the external feed pipe delivers hydrogen peroxide raw material solution to the first pipe 201. The hydrogen peroxide raw material solution flows into the first cylinder 2 until the liquid level is higher than the first opening 92. The first solenoid valve 202 is then closed, and the motor 205 is started. The motor 205 drives the first spur gear 206 to rotate, which in turn drives the second spur gear 207 to rotate. The second spur gear 207 drives the long rod 4 to rotate, which in turn drives the stirring blade 5 to rotate, stirring the hydrogen peroxide raw material solution. At the same time, the long rod 4 moves the parts on it. The gravity ball 10 pulls the first circular rod 9 under the action of centrifugal force, and the first circular rod 9 moves the movable plate 7 and the sealing ring 8. The movable plate 7 and sealing ring 8 are disengaged from the long rod 4, stopping the sealing of the first opening 92. At this time, the hydrogen peroxide raw material solution flows from the first opening 92 into the first cavity 91, carrying the modified activated carbon powder to the inside of the first cylinder 2. The stirring blade 5 continuously stirs the hydrogen peroxide raw material solution, making the hydrogen peroxide raw material solution and modified activated carbon powder fully mixed, removing the organic carbon in the hydrogen peroxide raw material solution. Then, the second solenoid valve 204 is opened, and the mixed solution flows from the second pipe 203 into the external discharge pipe. In use, the modified activated carbon powder is placed inside the stirring rod. While the stirring rod stirs the hydrogen peroxide raw material solution, the modified activated carbon powder inside it gradually flows into the hydrogen peroxide raw material solution for full mixing, avoiding the problem of insufficient mixing caused by activated carbon powder adhering to the stirring rod or container side wall above the liquid surface in the prior art.

[0035] Implementation Plan 2

[0036] Based on implementation plan 1, such as Figure 1-2 and Figure 6-8As shown, it also includes a feeding assembly; the feeding assembly is connected to the long rod 4; the feeding assembly includes a multi-stage hydraulic rod 208, a first connecting block 209, a second round rod 2010, a funnel 2011, a second cylinder 2012, and a stop block 2022; the multi-stage hydraulic rod 208 is fixedly connected to the cylinder cover 3; the first connecting block 209 is fixedly connected to the telescopic end of the multi-stage hydraulic rod 208; the second round rod 2010 is rotatably connected to the first connecting block 209, and the modified activated carbon powder is transferred to the inside of the long rod 4 through the second round rod 2010, avoiding the problem of clogging when the inside of the long rod 4 is wet and the modified activated carbon powder is poured directly from its top opening; the second round rod 2010 has a second cavity 93 inside; the second round rod 2010 has a second cavity 93 inside; the second round rod 2012 ... Rod 2010 is slidably connected to long rod 4; a funnel 2011 is connected and screwed to the upper end of the second round rod 2010, the funnel 2011 can be conical or square; the funnel 2011 is connected to the second cavity 93; a second cylinder 2012 is fixedly connected to the inner side of long rod 4, the second cylinder 2012 is made of alloy material; the second round rod 2010 and the second cylinder 2012 are slidably connected; two second openings 94 are opened on the lower side of the second round rod 2010, the second openings 94 are connected to the second cavity 93; two stops 2022 are fixedly connected to the inner side of long rod 4; the second round rod 2010 is in contact with the stops 2022; the stops 2022 cover the second openings 94.

[0037] Because the long rod 4 is used continuously, its interior is always damp. When modified activated carbon powder is poured into the first cavity 91, the powder adheres to the inner wall of the first cavity 91, causing blockage and resulting in feeding failure. At this time, the modified activated carbon powder is manually poured into the funnel 2011, and then flows from the funnel 2011 into the second cavity 93 of the second round rod 2010. The multi-stage hydraulic rod 208 is activated, which drives the first connecting block 209 to move upward. The first connecting block 209 drives the second round rod 2010 to move upward. The second round rod 2010 moves upward away from the stop block 2022, so that the second cavity 93 stops covering the second opening 94. The modified activated carbon powder in the second cavity 93 flows into the first cavity 91 through the second opening 94. As the second round rod 2010 moves upward, the modified activated carbon powder gradually fills the first cavity 91 from bottom to top, effectively avoiding blockage. The second round rod 2010 continues to move upward, aligning the lower side of the second round rod 2010 with the lower side of the second cylinder 2012. The cooperation of the second round rod 2010 and the second cylinder 2012 seals the first cavity 91, preventing the solution from entering the second round rod 2010 from the first cavity 91 during subsequent stirring. During the rotation of the long rod 4, the long rod 4 drives the second round rod 2010 and its parts to rotate together.

[0038] Implementation Plan 3

[0039] Based on implementation plan 2, such as Figure 1-2 and Figure 6-9 As shown, it also includes a toggle assembly; the toggle assembly is connected to the second round rod 2010; the toggle assembly includes a second connecting block 2013, a second elastic telescopic rod 2014, a third round rod 2015, a lever 2016, and a linkage unit; the second connecting block 2013 is welded to the inner side of the second round rod 2010, and the second connecting block 2013 is made of alloy material; the second elastic telescopic rod 2014 is fixedly connected to the lower side of the second connecting block 2013; the third round rod 2015 is fixedly connected to the telescopic end of the second elastic telescopic rod 2014; the third round rod 2015 is slidably connected to the second round rod 2010; several levers 2016 are passed through the third round rod 2015, and the modified activated carbon powder in the second round rod 2010 is toggled by the levers 2016 to make it fall smoothly and avoid blockage; the linkage unit is connected to the second round rod 2010; the linkage unit is used to drive the third round rod 2015 to move downward.

[0040] The actuating assembly also includes a first guide block 2017; the first guide block 2017 is welded to the inner side of the second round rod 2010; the first guide block 2017 is slidably connected to the third round rod 2015; the upper side of the first guide block 2017 is a conical surface, which can guide the modified activated carbon powder in the second round rod 2010 obliquely outward, so as to avoid the modified activated carbon powder remaining at the bottom of the second round rod 2010.

[0041] The linkage unit includes a spring block 2018 and a linkage block 2019; the spring block 2018 is welded to the lower side of the third round rod 2015; the spring block 2018 is in contact with the second round rod 2010; the spring block 2018 is in contact with the long rod 4; several linkage blocks 2019 are welded on the long rod 4; the linkage block 2019 cooperates with the spring block 2018, and while the second round rod 2010 moves upward, the linkage lever 2016 moves up and down reciprocally, agitating the modified activated carbon powder inside the second round rod 2010.

[0042] It also includes a second flow guide block 2020; a second flow guide block 2020 is welded to the upper and lower sides of each linkage block 2019. The second flow guide block 2020 guides the solution to the inner wall of the long rod 4, so that the solution impacts the inner wall of the long rod 4 and avoids the modified activated carbon powder from clumping and adhering to the inner wall of the long rod 4; the second flow guide block 2020 is provided with two arc surfaces.

[0043] It also includes a third flow guide block 2021; the third flow guide block 2021 is welded to the outside of the long rod 4, and the third flow guide block 2021 is located next to the first opening 92. More solution is guided to the first cavity 91 and the first opening 92 through the third flow guide block 2021.

[0044] The width of the third guide block 2021 increases from top to bottom.

[0045] Because the second cavity 93 is relatively small, the modified activated carbon powder may get stuck in the second cavity 93 and cannot fall automatically. Therefore, when the second round rod 2010 moves upward, the second round rod 2010 drives the elastic block 2018 to move upward and contact the linkage block 2019. The linkage block 2019 blocks and limits the elastic block 2018. Since the elastic coefficient of the elastic block 2018 is much greater than that of the second elastic telescopic rod 2014, the second round rod 2010 drives the second connecting block 2013 to continue moving upward. The elastic block 2018 and the third round rod 2015 remain stationary, stretching the second elastic telescopic rod 2014 until the second elastic telescopic rod 2014 is stretched to its maximum value. The second round rod 2010 continues to move upward, causing the elastic block 2018 to move upward. When the end of the elastic block 2018 bends downward and deforms, and the end of the elastic block 2018 does not overlap with the linkage block 2019 in the horizontal direction, the linkage block 2019 stops blocking and limiting the elastic block 2018, causing the second elastic telescopic rod 2014 to rebound and drive the third round rod 2015 to move upward quickly. Then, the elastic block 2018 continuously works in conjunction with multiple linkage blocks 2019, causing the third round rod 2015 to move up and down relative to the second round rod 2010. The third round rod 2015 drives the lever 2016 to move up and down. The lever 2016 repeatedly moves the modified activated carbon powder in the second cavity 93, allowing it to fall smoothly, effectively avoiding the problem of the modified activated carbon powder getting stuck in the second cavity 93 and unable to fall automatically.

[0046] When the modified activated carbon powder flows out of the second cavity 93, some powder will remain at the bottom of the second cavity 93. Therefore, a first guide block 2017 is set at the bottom of the second cavity 93 to guide the modified activated carbon powder out of the second cavity 93 and avoid residue.

[0047] During the stirring process, the long rod 4 drives the third guide block 2021 to perform circular motion, so that the third guide block 2021 guides more solution to the first opening 92 and the first cavity 91, thereby allowing the solution to quickly flush out the modified activated carbon powder in the first cavity 91, which helps to improve the mixing efficiency.

[0048] Because the modified activated carbon powder has a certain gravity, the modified activated carbon powder in the lower part of the first cavity 91 is relatively compact. At this time, by increasing the width of the third guide block 2021 from top to bottom, more solution is guided into the lower part of the first cavity 91, and the modified activated carbon powder in each position of the first cavity 91 is evenly flushed out, which helps to improve the mixing uniformity and further improve the mixing efficiency.

[0049] After the solution flows into the first opening 92, it is guided to the inner wall of the long rod 4 by the second guide block 2020, so that the solution impacts the inner wall of the long rod 4 and avoids the modified activated carbon powder from adhering and remaining on the inner wall of the long rod 4.
