Description

Technical Field

[0001] The present invention belongs to the technical field of nitric acid decolorization, and specifically relates to a microelectronic nitric acid decolorization device. Background Art

[0002] Microelectronic technology covers processes such as system circuit design, electronic device technology, and material preparation. During the production of microelectronic products, nitric acid is usually used as an etching solution. To prevent the etching solution from turning yellow and affecting the etching effect, it is necessary to first treat the nitrogen dioxide impurities in the nitric acid. Usually, nitrogen dioxide in the nitric acid is removed through a nitrogen reaction for decolorization. However, the current equipment has low efficiency in removing impurities and decolorizing, and the reaction between the reaction gas and nitric acid is insufficient, which affects the decolorization effect of nitric acid and the performance of the etching solution.

[0003] After retrieval, the existing patent (publication number: CN216726789U) discloses a nitric acid decolorization device for microelectronics, including a bottom plate and a driving motor. The bottom plate is provided with a triangular support frame and a side support plate. The triangular support frame is provided with a decolorization device body. The top of the decolorization device body is provided with a feed pipe, and a first sealing cover is installed on the feed pipe. The bottom of the decolorization device body is provided with a discharge pipe, and a second sealing cover is installed on the discharge pipe. A transmission shaft is installed on the decolorization device body, a first belt pulley is installed on the transmission shaft, and a conveyor belt is arranged on the belt pulley. In this nitric acid decolorization device for microelectronics, a sound-absorbing cotton layer is provided on the inner wall of the decolorization device body, which can absorb the noise generated during the stirring process, prevent noise from harming the bodies of workers, and improve the use effect of the nitric acid decolorization device for microelectronics.

[0004] However, in the actual use process, the air outlet and the stirring frame rotate simultaneously and synchronously, which may cause the nitric acid solution to rotate at the same rate as the stirring frame, and the gas discharged from the air outlet rotates synchronously with the stirring frame. As a result, the gas and the liquid only make local contact and then rise through buoyancy, reducing the reaction rate.

[0005] Therefore, the present invention provides a microelectronic nitric acid decolorization device. Summary of the Invention

[0006] In order to make up for the deficiencies of the existing technology and solve the problem that the air outlet and the stirring frame rotate simultaneously and synchronously, which may cause the nitric acid solution to rotate at the same rate as the stirring frame, and the gas discharged from the air outlet rotates synchronously with the stirring frame.

[0018] 1.

Then, it is evenly shunted and transported into the nitric acid liquid through the air outlet holes on the outside of the inner pipe. At the same time, the gas that has not been completely shunted is transported into the bottom air outlet disc through the dust-proof pipe for shunting and transporting into the nitric acid liquid to react with the nitric acid for the second reaction. While solving the problem that the gas rotates synchronously with the liquid and affects the contact area, it also performs a second reaction on the gas that has not been completely reacted during the reaction process.

[0036] Example 1:

[0037] As Figures 1 to 13As shown in the figure, a microelectronic nitric acid decolorization device according to the present invention includes a decolorization barrel 1. Inside the decolorization barrel 1, a corrugated barrel 11 is fixedly connected. The decolorization barrel 1 fixes the corrugated barrel 11, and a temperature sensor is arranged at the top of the decolorization barrel 1 to monitor the internal temperature in real time. A cavity is arranged between the decolorization barrel 1 and the corrugated barrel 11. The cavity is divided into two left and right cavities by two front and rear partition plates. The cavity formed between the decolorization barrel 1 and the corrugated barrel 11 is separated by the two front and rear partition plates to form two independent spaces. The bottom end of the corrugated barrel 11 is fixedly connected with an air outlet plate 88. The outer side of the top end of the air outlet plate 88 is fixedly connected with the bottom end of the decolorization barrel 1. The bottom end of the cavity is sealed by the air outlet plate 88. The front part on the left side of the top end of the decolorization barrel 1 is fixedly connected with a feed pipe 111. The left side of the top end of the feed pipe 111 is fixedly connected with an activated carbon pipe 112. The corrugated barrel 11 and the activated carbon pipe 112 are connected through the feed pipe 111, so that the activated carbon in the activated carbon pipe 112 can adsorb the pigment in the nitric acid before the nitric acid enters the corrugated barrel 11. The rear part on the left side of the top end of the decolorization barrel 1 is fixedly connected with an air inlet pipe 1 12. The air inlet pipe 1 12 is fixedly communicated with the corrugated barrel 11. The decolorization barrel 1 fixes the air inlet pipe 1 12, and the hydrogen for decolorization is transported into the corrugated barrel 11 through the air inlet pipe 1 12. The middle part on the left side of the top end of the decolorization barrel 1 is fixedly connected with a transmission box 2. The decolorization barrel 1 fixes the transmission box 2. Symmetric transmission components are arranged on the outer side of the transmission box 2. The top end of the transmission box 2 is fixedly connected with a motor 21. The transmission box 2 supports and fixes the motor 21. The output end of the motor 21 is fixedly connected with a bevel gear 1 22. The bevel gear 1 22 drives a bevel gear 2 23 to rotate. The bevel gear 2 23 is rotatably connected with the transmission box 2. The transmission box 2 limits the bevel gear 2 23, and thus a seal is arranged to seal between the transmission box 2 and the bevel gear 2 23. The right side of the bottom end of the bevel gear 2 23 is meshed with a bevel gear 3 24. The bevel gear 2 23 drives the bevel gear 3 24 to rotate. The bevel gear 3 24 is rotatably connected with the transmission box 2. The transmission box 2 limits the bevel gear 3 24, and thus a seal is arranged to seal between the transmission box 2 and the bevel gear 3 24. The bottom end of the bevel gear 3 24 is fixedly connected with a transmission rod 1 25. The outer side of the bottom end of the transmission rod 1 25 is fixedly connected with a stirring blade 26. The bevel gear 3 24 drives the transmission rod 1 25 and the stirring blade 26 to rotate at the same time. The right side of the top end of the corrugated barrel 11 is fixedly connected with an air extraction pipe 85. The corrugated barrel 11 fixes the air extraction pipe 85. One end of the air extraction pipe 85 is fixedly connected with a dust-proof pipe 86 through a gas valve (the gas valve is a common corrosion-resistant gas valve for sealing, which is a prior art). The communication between the air extraction pipe 85 and the dust-proof pipe 86 is controlled by the gas valve. A compensation component is arranged at the top end of the air extraction pipe 85. The rear side of the bottom end of the air extraction pipe 85 is fixedly connected with an air pump 84. The left side of the air pump 84 is fixedly connected with an air inlet pipe 2 83.The hydrogen gas at the top of the corrugated barrel 11 is extracted by the air pump 84 using the suction pipe 85, and at the same time, it is output using the second inlet pipe 83. The second inlet pipe 83 is fixedly connected to the decolorization barrel 1. The second inlet pipe 83 passes through the cavity between the decolorization barrel 1 and the corrugated barrel 11 and is not connected to the cavity. The bottom end of the second inlet pipe 83 is fixedly connected to the inner pipe 810. The second inlet pipe 83 is connected to the inner pipe 810, so that the hydrogen gas transported through the second inlet pipe 83 enters the inner pipe 810 and continues to be transported. The outer wall of the outer side of the inner pipe 810 is fixedly connected with evenly distributed air outlet holes 82. The hydrogen gas is shunted by the inner pipe 810, so that it enters the air outlet holes 82, and the gas is atomized and ejected through the air outlet holes 82 to form fine bubbles, which are mixed and reacted with nitric acid. The front side of the bottom end of the inner pipe 810 is fixedly connected with the third connecting pipe 87. The front end of the third connecting pipe 87 is fixedly connected with the air outlet disc 88. The third connecting pipe 87 is used to connect the inner pipe 810 and the air outlet disc 88, so that the unshunted gas enters the air outlet disc 88 and continues to be atomized and ejected.,

[0038] The compensation component includes the second fixing frame 51. The top end of the suction pipe 85 is fixedly connected with the compensation bottle 5. The compensation bottle 5 is supported and fixed by the suction pipe 85. The inner side of the compensation bottle 5 is fixedly connected with the second fixing frames 51 that are symmetrically arranged up and down. A limiting rod 52 is fixedly connected between the two second fixing frames 51. The compensation bottle 5 is used to fix the second fixing frame 51, and at the same time, the second fixing frame 51 is used to fix the limiting rod 52. A piston 53 is slidably connected to the outer side of the limiting rod 52. The limiting rod 52 is used to limit the piston 53. Thus, by the up and down movement of the piston 53, the pressure inside the equipment is adjusted.,

[0039] The transmission assembly includes a first driven gear 35. A second connecting rod 31 is fixedly connected to the outside of the bevel gear 23. The second connecting rod 31 is fixed by the bevel gear 23. A transmission box 3 is rotatably connected to the outside of the second connecting rod 31. The transmission box 3 is fixedly connected to the decolorizing barrel 1. A connecting component is arranged on the right side of the bevel gear 23. The second connecting rod 31 is rotatably connected to the transmission box 3. The transmission box 3 limits the second connecting rod 31. A first driving gear 32 is fixedly connected to one end of the outside of the second connecting rod 31. The first driving gear 32 is fixed by the second connecting rod 31. At the same time, the bevel gear 23 drives the first driving gear 32 to rotate by means of the second connecting rod 31. A third transmission rod 33 is fixedly connected to one end of the outside of the first driving gear 32. The third transmission rod 33 is fixed by the first driving gear 32. The first driving gear 32 is meshed with the first driven gear 35 at the top. The first driving gear 32 drives the first driven gear 35 to rotate. A fourth transmission rod 36 is fixedly connected to one end of the outside of the first driven gear 35. The fourth transmission rod 36 is fixed by the first driven gear 35. A first set of evenly distributed fan blades 34 is fixedly connected to the outside of the third transmission rod 33 on the left side of the transmission box 2. The first set of fan blades 34 is fixed by the third transmission rod 33 on the left side. At the same time, the third transmission rod 33 on the left side drives the first set of fan blades 34 to rotate. A second set of evenly distributed fan blades 37 is fixedly connected to the outside of the fourth transmission rod 36 on the left side of the transmission box 2. The second set of fan blades 37 is fixed by the fourth transmission rod 36 on the left side. At the same time, the fourth transmission rod 36 on the left side drives the second set of fan blades 37 to rotate. A propeller 41 is fixedly connected to the outside of the third transmission rod 33 on the right side of the transmission box 2. The propeller 41 is driven to rotate by the third transmission rod 33 on the right side, so as to extract the cooling and lubricating liquid on the right side of the sealed chamber 4 (the cooling and lubricating liquid is a fully synthetic gear oil ) and convey it to the left. The reason for using the cooling and lubricating liquid instead of water is that the cooling and lubricating liquid not only provides excellent anti-wear ability but also is beneficial for heat dissipation. At the same time, water is used as the coolant because the evaporation rate of oil is lower than that of water. Therefore, in the cooling system under high-temperature environments, the consumption and replenishment frequency of oil are much lower than those of water, thus reducing the operating cost. And oil can maintain physical and chemical stability in a temperature range from very low to very high, which makes it suitable for applications under extreme climate and temperature conditions. A power transmission component is arranged at the outer end of the fourth transmission rod 36 on the right side of the transmission box 2. The transmission box 2 is connected to the transmission boxes 3 on both sides through a first connecting pipe 6. The first connecting pipe 6 enables the transmission boxes 3 on both sides to communicate with the middle transmission box 2 with each other and be connected in series.

[0040] At the top of the left conduction box 3, there is a second oil inlet pipe 61 fixedly connected. At the bottom left end of the second oil inlet pipe 61, there is a heat dissipation box 7 fixedly connected. The second oil inlet pipe 61 is used to connect the heat dissipation box 7.

At the bottom of the heat dissipation box 7, there is a first oil outlet pipe 62 fixedly connected, and the first oil outlet pipe 62 is connected to the communication hole 71. The first oil outlet pipe 62 is connected to the left cavity between the decoloring barrel 1 and the corrugated barrel 11. The cooling and lubricating liquid is transported into the top end inside the communication hole 71 through the second oil inlet pipe 61, and then moves downward through the communication hole 71. During this process, the heat of the cooling and lubricating liquid is transferred to the heat dissipation plate 73 through the inner wall of the ventilation hole 72. At the same time, the first fan blade 34 and the second fan blade 37 blow air to the left, so as to exchange the heat on the inner wall of the heat dissipation plate 73 with the flowing air, thereby realizing the heat dissipation function.

[0041] At the bottom right of the left cavity, there is a third oil inlet pipe 89 fixedly connected. On the right side of the third oil inlet pipe 89, there is an outer pipe 81 fixedly connected. The third oil inlet pipe 89 is used to connect the left cavity and the outer pipe 81. The outer pipe 81 is sleeved outside the inner pipe 810, and both the outer pipe 81 and the inner pipe 810 are arranged in a spiral shape. One end of the outer pipe 81 is fixedly connected to the outer wall of the inner pipe 810, and both ends of the outer pipe 81 are connected to the inner pipe 810.

Through the air outlet hole 82, the internal space of the inner pipe 810 is connected to the external space of the outer pipe (81). Through the air outlet hole 82, the internal space of the inner pipe 810 is connected to the outside, so that the cooling and lubricating liquid flows through the space between the outer pipe 81 and the inner pipe 810. And hydrogen enters the inner pipe 810 through the second inlet pipe 83, and the hydrogen is refined through the air outlet hole 82, becoming fine small bubbles and being transported into the nitric acid to react with the nitric acid for decolorization. On the top right of the outer pipe 81, there is a second oil outlet pipe 8 fixedly connected. The right side of the second oil outlet pipe 8 is connected to the right cavity. Through the second oil outlet pipe 8, the inner space of the outer pipe 81 is connected to the right cavity, so that the cooling and lubricating liquid can flow through the space between the outer pipe 81 and the inner pipe 810.

[0047] The reason why the output end of the motor 21, the transmission component and the power transmission component adopt multiple components such as bevel gears, connecting rods, transmission rods, driving gears, driven gears, etc. is that when the decolorization reaction is carried out in the decolorization barrel 1, it is necessary to perform efficient heat dissipation treatment according to the actual situation. However, in the prior art, an additional cooling circulation device needs to be provided, which occupies a large area. In order to ensure that the problem of excessive heat generation during the reaction is solved centrally in one device, and at the same time, the overall operation of stirring and heat dissipation can be ensured, the above-mentioned parts are provided to integrate the stirring and overall heat dissipation operations. It is not to set up a complex structure, but to integrate the original cooling circulation device on the decolorization barrel 1 of the present invention and combine it with the power of stirring. That is, it ensures the stirring state and can effectively ensure the heat dissipation state. The integrated operation can effectively reduce the overall floor area of the device, and it is also convenient to operate simultaneously. It also refers to the vehicle braking system in the prior art for optimization and integration. It is not a complex mechanism to solve simple problems, but an integrated combination operation.

[0048] Working principle: When the microelectronic nitric acid decolorization device is operating, first, the internal space of the corrugated barrel 11 is evacuated to ensure that no other gases affect the reaction. Then, nitric acid is transported into the corrugated barrel 11 through the activated carbon tube 112 and the feed pipe 111. At the same time, the colored substances in the nitric acid are adsorbed by the activated carbon tube 112. Then, the unadsorbed colored substances enter the corrugated barrel 11 together with the nitric acid. Then, hydrogen is injected into the corrugated barrel 11 through the first intake pipe 12. After the hydrogen and nitric acid reach the injection volume, the feed pipe 111 and the first intake pipe 12 are closed. Then, the motor 21 drives the first bevel gear 22 to rotate. Then, the first bevel gear 22 drives the third bevel gear 24, the first transmission rod 25, and the stirring blade 26 to rotate simultaneously through the second bevel gear 23, so as to stir the nitric acid. At the same time, under the action of centrifugal force, the nitric acid moves outward to form a vortex. Finally, the lowest surface of the vortex contacts the bottom part of the stirring blade 26 and leaks out the upper half part. Thus, during the rotation of the stirring blade 26, the hydrogen above the liquid surface is transported into the nitric acid simultaneously during the rotation, so that the nitric acid and hydrogen are mixed for the first time. At the same time, the air pump 84 uses the suction pipe 85 to extract the hydrogen at the top of the corrugated barrel 11 and transports it into the inner tube 810 through the second intake pipe 83. The hydrogen is refined through the air holes 82 on the outer side of the inner tube 810 to generate fine bubbles, which are directly transported into the vortex to increase the contact area between hydrogen and nitric acid, thereby improving the reaction rate. The unshunted hydrogen enters the air outlet disc 88 through the third connecting pipe 87 and is refined again through the air outlet disc 88 to generate bubbles and be transported into the vortex from the bottom. The nitric acid is decolorized by hydrogen. Hydrogen, as a reducing agent, reacts with the colored impurities in the nitric acid. These impurities are often organic substances or oxides of certain metal ions, and they can be reduced to colorless or lighter-colored forms by accepting electrons in the hydrogen. The reaction usually takes place in the presence of a catalyst. Heat is generated during this process. When hydrogen is decolorizing nitric acid, catalysts such as platinum or palladium exhibit the best activity at a specific temperature. Usually, these catalysts can effectively promote the reaction between hydrogen and nitric acid in the medium temperature range, such as 50°C to 130°C. When the temperature is higher than 130°C, the temperature sensor installed inside the corrugated barrel 11 controls the electric push rod 38 to extend, driving the limit gear disc 39 to move to the right, so that the limit gear disc 39 engages with the engaging gear disc 310. Thus, the second bevel gear 23 drives the right connecting rod 31 to rotate through the connecting component, and then drives the propeller 41 to rotate through the right connecting rod 31. Thus, the cooling and lubricating liquid integrated on the right side of the propeller 41 is extracted and transported to the left side, and then enters the conduction box 3 through the connecting pipe 63. Then, it enters the transmission box 2 through the first connecting pipe 6 between the conduction box 3 and the transmission box 2. The cooling and lubricating liquid integrated enters the left conduction box 3 again through the left first connecting pipe 6, and finally enters the communication hole 71 through the second oil inlet pipe 61.Meanwhile, the left transmission rod three 33 and the transmission rod four 36 drive the first fan blade 34 and the second fan blade 37 to rotate, so as to convey the external cold air into the heat dissipation plate 73, and displace the heat transferred from the cooling and lubricating liquid in the communication hole 71 to the inner wall of the ventilation hole 72 onto the heat dissipation plate 73, thereby realizing the heat dissipation function. The cooled cooling and lubricating liquid enters the left cavity formed between the decolorizing barrel 1 and the corrugated barrel 11 through the first oil outlet pipe 62, and extrudes the original cooling and lubricating liquid, so that the cooling and lubricating liquid enters the space formed between the outer pipe 81 and the inner pipe 810 through the third oil inlet pipe 89, and thus directly contacts with the nitric acid eddy current through the outer pipe 81 for efficient cooling, and at the same time avoids the occurrence of local high temperature caused by violent local reaction. After that, the cooling and lubricating liquid enters the right cavity between the decolorizing barrel 1 and the corrugated barrel 11 through the second oil outlet pipe 8, and is re-transported back into the sealed chamber 4 through the first oil inlet pipe 48, and the filter plate 46 is used to filter the cooling and lubricating liquid to prevent the iron filings and impurities generated during the operation of the equipment from flowing inside the equipment. At the same time, the right transmission rod four 36 drives the second driving gear 42 to rotate, and the second driving gear 42 drives the cleaning rod 45 to rotate through the second driven gear 43 to clean the right surface of the filter plate 46, push the impurities around, and collect the impurities by using the collecting bottle 47. The filtered cooling and lubricating liquid continues to circulate through the extraction of the propeller 41. After the reaction is completed, the nitric acid is extracted by the water pump 91 through the first water inlet pipe 9 and conveyed out through the second water inlet pipe 92.,
