Description

Technical Field

[0001] This invention belongs to the field of nitric acid decolorization technology, specifically a microelectronic nitric acid decolorization device. Background Technology

[0002] Microelectronics technology encompasses processes such as system circuit design, electronic device technology, and materials preparation. In the manufacturing process of microelectronic products, nitric acid is commonly used as an etching solution. To prevent the etching solution from yellowing and affecting the etching effect, nitrogen dioxide impurities in the nitric acid must be treated first. Typically, nitrogen dioxide is removed from the nitric acid through a nitrogen reaction for decolorization. However, current equipment is inefficient in removing impurities and decolorizing, and the reaction between the reacting gas and nitric acid is incomplete, which affects the decolorization effect of the nitric acid and the performance of the etching solution.

[0003] A search revealed an existing patent (publication number: CN216726789U) disclosing a nitric acid decolorization device for microelectronics, comprising a base plate and a drive motor. The base plate is equipped with a triangular support frame and side support plates. The decolorization device body is mounted on the triangular support frame. A feed pipe with a first sealing cap is located at the top of the decolorization device body, and a discharge pipe with a second sealing cap is located at the bottom of the device body. A drive shaft with a first pulley and a conveyor belt are mounted on the pulley. This nitric acid decolorization device for microelectronics features a sound-absorbing cotton layer on the inner wall of the device body, which absorbs noise generated during stirring, preventing noise from harming workers and improving the device's effectiveness.

[0004] However, in actual use, the vent and the stirring rack rotate synchronously. This may cause the nitric acid solution to rotate at the same speed as the stirring rack, while the gas discharged from the vent rotates synchronously with the stirring rack. As a result, the gas and liquid only make local contact before rising due to buoyancy, thus reducing the reaction rate.

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

[0006] To overcome the shortcomings of existing technologies and solve the problem that the simultaneous synchronous rotation of the vent and the stirring rack may cause the nitric acid solution to rotate at the same speed as the stirring rack, while the gas discharged from the vent rotates synchronously with the stirring rack, resulting in the gas and liquid only making local contact before rising due to buoyancy and reducing the reaction rate, this invention proposes a microelectronic nitric acid decolorization device.

[0017] The beneficial effects of this invention are as follows:

[0018] 1.

A water inlet pipe 9 is fixedly connected to the right side of the bottom end of the decolorizing tank 1.

[0047] The aforementioned components, including multiple bevel gears, connecting rods, transmission rods, driving gears, and driven gears, are used in the output end of motor 21, transmission components, and power transmission components because efficient heat dissipation is required during the decolorization reaction in the decolorization tank 1, depending on the actual situation. However, existing technologies require additional cooling circulation devices, which occupy a large area. To ensure that the problem of excessive heat during the reaction is solved in one device, while ensuring the overall operation of stirring and heat dissipation, the aforementioned components are provided to integrate stirring and overall heat dissipation. This is not about setting up a complex structure, but rather integrating the original cooling circulation device into the decolorization tank 1 of this invention and combining it with the stirring power. This ensures both stirring and effective heat dissipation. The integrated operation effectively reduces the overall footprint of the device and facilitates simultaneous operation. It also refers to the optimization and integration of vehicle braking systems in existing technologies. It is not about solving a simple problem with a complex mechanism, but rather about integrated operation.

[0048] Working Principle: During operation of the microelectronic nitric acid decolorization device, the internal space of the corrugated tank 11 is first evacuated to ensure no other gases affect the reaction. Then, nitric acid is fed into the corrugated tank 11 through the activated carbon tube 112 and the feed pipe 111. Simultaneously, the activated carbon tube 112 adsorbs colored substances in the nitric acid. The unadsorbed colored substances then enter the corrugated tank 11 along with the nitric acid. Next, hydrogen is injected into the corrugated tank 11 through the gas inlet pipe 12. After the hydrogen and nitric acid have reached the required injection volume, the feed pipe 111 and the gas inlet pipe 12 are closed. Then, the motor 21 drives the bevel gear 22 to rotate. The bevel gear 22, through the bevel gear 23, simultaneously drives the bevel gear 24, the transmission rod 25, and the agitator. The stirring blade 26 rotates, thus stirring the nitric acid. Simultaneously, under centrifugal force, the nitric acid moves outward, forming a vortex. Finally, the lowest surface of the vortex contacts the bottom of the stirring blade 26, while the upper part leaks out. This allows the stirring blade 26 to simultaneously deliver hydrogen gas from above the liquid surface into the nitric acid during rotation, initiating the first mixing of nitric acid and hydrogen. Simultaneously, the air pump 84 uses the extraction pipe 85 to extract hydrogen gas from the top of the corrugated tank 11 and delivers it into the inner tube 810 through the second air inlet pipe 83. The hydrogen gas is then refined through the air outlet 82 on the outside of the inner tube 810, generating fine bubbles that are directly introduced into the vortex, increasing the contact area between hydrogen and nitric acid and thus improving the reaction rate. This process also addresses any remaining hydrogen gas. Hydrogen gas enters the outlet plate 88 through connecting pipe 3 87, where it undergoes further refining. Bubbles are generated and transported from the bottom into the vortex. Hydrogen gas is used to decolorize nitric acid. As a reducing agent, hydrogen reacts with colored impurities in nitric acid. These impurities are often organic compounds or oxides of certain metal ions, which can be reduced to colorless or lighter-colored forms by accepting electrons from hydrogen gas. The reaction usually occurs in the presence of a catalyst, generating heat. Catalysts such as platinum or palladium exhibit optimal activity at specific temperatures during the decolorization of nitric acid. Typically, these catalysts effectively promote the reaction between hydrogen and nitric acid in the medium temperature range, such as 50°C to 130°C. At temperatures above 130°C... At 0℃, the temperature sensor inside the corrugated tank 11 controls the extension of the electric push rod 38, causing the limiting gear 39 to move to the right, engaging with the engaging gear 310. This, through the bevel gear 23 and the connecting assembly, drives the right connecting rod 31 to rotate, which in turn drives the propeller 41 to rotate. This draws the integrated cooling and lubricating fluid from the right side of the propeller 41 and transports it to the left. The fluid then enters the transmission box 3 through the connecting pipe 63, then enters the transmission box 2 through the connecting pipe 6 between the transmission box 3 and the transmission box 2. The integrated cooling and lubricating fluid then enters the left transmission box 3 through the left connecting pipe 6, and finally enters the connecting hole 71 through the oil inlet pipe 61.Simultaneously, the left-side transmission rods 33 and 36 drive the fan blades 34 and 37 to rotate, thereby delivering external cold air into the heat sink 73. This displaces the heat transferred from the connecting hole 71 to the heat sink 73 via the ventilation hole 72, thus achieving heat dissipation. The cooled lubricating fluid then enters the left cavity formed between the decolorizing tank 1 and the corrugated tank 11 through the oil outlet pipe 62, squeezing out the original lubricating fluid and forcing it through the oil inlet pipe 89 into the space between the outer pipe 81 and the inner pipe 810. This allows the lubricating fluid to directly contact the nitric acid vortex through the outer pipe 81, achieving efficient cooling while preventing localized high temperatures caused by intense local reactions. The oil enters the right-side cavity between the decolorizing tank 1 and the corrugated tank 11 through the oil outlet pipe 28, and is then transported back to the sealed chamber 4 through the oil inlet pipe 18. The cooling and lubricating fluid is filtered by the filter plate 46 to prevent iron filings and impurities generated during equipment operation from flowing inside the equipment. Simultaneously, the right-side transmission rod 46 drives the drive gear 2 42 to rotate, which in turn drives the cleaning rod 45 through the driven gear 2 43 to clean the right-side surface of the filter plate 46 and push impurities outwards. The impurities are collected by the collection bottle 47. The filtered cooling and lubricating fluid continues to circulate through the propeller 41. After the reaction is complete, the nitric acid is extracted by the water pump 91 through the water inlet pipe 1 9 and transported out through the water inlet pipe 2 92.
