Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and more specifically, it relates to a deammoniation reaction vessel for synthesizing gold extraction agents. Background Technology

[0002] Gold extraction agent is a chemical agent used in the gold beneficiation process. During production, it can leach gold from the ore and separate the gold from other metallic or non-metallic impurities. In the synthesis of gold extraction agent, ammonia or ammonium salts are often used as intermediates to regulate the synthesis process. After preparation, ammonia removal treatment is required.

[0003] Common deammoniation processes utilize deammoniation reactors, which typically have a simple structure. During operation, the stirring mechanism used to agitate and mix the ammonia, promoting a more uniform internal temperature and ammonia distribution, is quite basic. It simply involves a few blades driven by a power unit to rotate, resulting in limited mixing effectiveness and impacting the reactor's processing efficiency. Furthermore, common reactors only have an exhaust system, lacking gas handling capabilities. The ammonia gas released from the reaction is directly emitted into the working environment, causing pollution and affecting nearby workers. Additionally, when agitating the gold extraction agent, the simple stirring structure only allows for horizontal agitation. The gold extraction agent at different heights flows solely by gravity, resulting in low mixing efficiency and further hindering the deammoniation reaction. Utility Model Content

[0030] Please see Figure 1-5 A deammoniation reaction vessel for synthesizing gold extraction agents includes a vessel body 1, a drive motor 2 on the vessel body 1, a drive tube 3 rotatably connected to the vessel body 1, a drive shaft 4 rotatably connected inside the drive tube 3, a drive bevel gear 5 on the drive motor 2, a driven bevel gear 6 on both the drive tube 3 and the drive shaft 4, the drive bevel gear 5 and the driven bevel gear 6 cooperating, an extension frame 7 at the lower end of the drive shaft 4, and stirring blades 8 on both the drive tube 3 and the extension frame 7.

[0031] The vessel body 1 is equipped with an exhaust pipe 9, and a purification box 10 is provided at one end of the exhaust pipe 9. The purification box 10 is equipped with a wire mesh demister 11, a cooling pipe 12 and an activated carbon adsorption layer 13. The wire mesh demister 11, the cooling pipe 12 and the activated carbon adsorption layer 13 are arranged in sequence. The outer end of the purification box 10 is equipped with a water inlet pipe 14 and a water outlet pipe 15. Both the water inlet pipe 14 and the water outlet pipe 15 are matched with the cooling pipe 12.

[0032] In this embodiment, the processing capacity is provided by the vessel body 1. When the gold extraction agent material is deaminated, the power is provided by the drive motor 2. The drive motor 2 drives the active bevel gear 5 to rotate. The rotation of the active bevel gear 5 cooperates with the driven bevel gear 6, causing the drive tube 3 and the drive shaft 4 to rotate. The transmission directions of the two driven bevel gears 6 are opposite, causing the drive tube 3 and the drive shaft 4 to rotate in different directions with their respective stirring blades 8, making the stirring more efficient.

[0033] More specifically, the exhaust structure is provided through the exhaust pipe 9. When the reactor is working, the ammonia gas released is discharged from the exhaust pipe 9 and enters the purification chamber 10 through the exhaust pipe 9. It first comes into contact with the wire mesh demister 11 to intercept the mist droplets generated by the reaction. Then it comes into contact with the ammonia gas through the cooling pipe 12. Cooling water is introduced into the water inlet pipe 14 so that the cooling water flows along the cooling pipe 12 to cool the gas flow. Most of the ammonia gas is condensed into ammonia water and left in the purification chamber 10 to be removed. At the same time, the temperature of the ordinary gas flow is reduced and discharged into the external space at a suitable temperature. The ammonia gas that has been condensed finally comes into contact with the activated carbon adsorption layer 13. The activated carbon adsorption layer 13 further absorbs the ammonia concentration in the gas, making the discharged gas cleaner.

[0034] Please see Figure 2 As one implementation of agitation: the agitator blade 8 includes an upper blade 16, a middle blade 17 and a lower blade 18, with the upper blade 16 inclined upward and the lower blade 18 inclined downward.

[0035] Specifically, the middle blade 17 rotates in the middle part of the vessel body 1 to perform the main stirring, while the upward tilting upper blade 16 causes the water to flow downward and the downward tilting lower blade 18 causes the water to flow upward, so that the liquid at the upper and lower ends move towards the middle, and the gold extraction agent at different heights is mixed, thereby improving the stirring effect.

[0036] Please see Figure 1 As a further embodiment of the vessel body: an observation port 19 is provided on the vessel body 1, and a protective glass 20 is provided at the observation port 19.

[0037] Specifically, the observation port 19 provides an observation structure, which remains stable under the protection of the protective glass 20, making it convenient for workers to judge the treatment effect of the gold extraction agent.

[0038] Please see Figure 2 As a further embodiment of the vessel body: the vessel body 1 is provided with a bracket 21, and a support ring 22 is rotatably connected to the bracket 21, and the support ring 22 cooperates with the drive shaft 4.

[0039] Specifically, the support structure is provided by bracket 21, and the drive shaft 4 is kept stable by the cooperation of support ring 22 with drive shaft 4.

[0040] Please see Figure 3 As a further embodiment of the extension frame: the outer end of the extension frame 7 is provided with a cleaning scraper 23, and the lower end is provided with a cleaning base plate 24. Both the cleaning scraper 23 and the cleaning base plate 24 are in conjunction with the vessel body 1.

[0041] Specifically, when the extension frame 7 rotates, it will clean the inner wall of the vessel 1 by contacting the side wall inside the vessel 1 through the cleaning scraper 23 and the bottom wall inside the vessel 1 through the cleaning base plate 24.

[0042] Please see Figure 1 As a further implementation of the purification box: a negative pressure fan 25 is provided at one end of the purification box 10.

[0043] Specifically, by controlling the operation of the negative pressure fan 25, the gas inside the vessel 1 can be discharged as much as possible when needed, reducing the amount of ammonia remaining inside the vessel 1.

[0044] Please see Figure 1 As a further embodiment of the vessel body: the vessel body 1 is provided with a balance air pipe 26, and the balance air pipe 26 is provided with a one-way valve 27.

[0045] Specifically, the venting structure is provided by the balancing pipe 26. When the gas inside the vessel 1 is discharged and the internal air pressure becomes low, outside air is introduced into it through the balancing pipe 26, and the one-way valve 27 controls the gas inside the vessel 1 to prevent it from being discharged from the balancing pipe 26.

[0046] Please see Figure 1 and Figure 4 As a further embodiment of the vessel body: a water supply tank 28 is provided at the outer end of the vessel body 1, a water supply pump 29 is provided at one end of the water supply tank 28, a condenser 30 is provided at one end of the water supply pump 29, the condenser 30 is connected to the inlet pipe 14, and the outlet pipe 15 is connected to the water supply tank 28.

[0047] Specifically, water is supplied through water supply tank 28 and pressure is provided through water supply pump 29, causing the water in water supply tank 28 to flow outward. The water flow is processed by condenser 30, and after the water flow temperature is reduced, it is passed into cooling pipe 12 for cooling, and the circulation is maintained under the action of water supply pump 29.

[0048] In summary, when the overall equipment is in use (or running):

[0049] When using the equipment, the processing capacity is provided by the vessel body 1. The equipment is connected to an external power source, and sufficient reagents are added to the vessel body 1 to provide deaming treatment for the propellant. During the deaming treatment of the gold extraction agent material, power is provided by the drive motor 2, which drives the active bevel gear 5 to rotate. The rotation of the active bevel gear 5 cooperates with the driven bevel gear 6, causing the drive tube 3 and drive shaft 4 to rotate. The bracket 21 provides a support structure, and the support ring 22 cooperates with the drive shaft 4 to keep the drive shaft 4 stable. The two driven bevel gears 6 have opposite transmission directions, causing the drive tube 3 and drive shaft 4 to rotate in different directions with their respective stirring blades 8, making the stirring more efficient. During stirring, the middle blade... The blade 17 rotates in the middle of the vessel 1 to perform the main agitation. The upward-sloping upper blade 16 causes the water to flow downward, while the downward-sloping lower blade 18 causes the water to flow upward, bringing the liquids at the upper and lower ends closer to the middle. This mixes the gold extractant at different heights and improves the agitation effect. The observation port 19 provides an observation structure and remains stable under the protection of the protective glass 20, making it convenient for workers to judge the treatment effect of the gold extractant. In addition, when the extension frame 7 rotates, it contacts the inner side wall of the vessel 1 through the cleaning scraper 23 and the inner bottom wall of the vessel 1 through the cleaning bottom plate 24. During the movement, the inner wall of the vessel 1 is cleaned, treating the ammonium salt crystals generated on the inner wall of the vessel 1 by the treatment reaction.

[0050] During reactor operation, the released ammonia gas is discharged from exhaust pipe 9 and enters purification tank 10 through exhaust pipe 9. It first contacts the wire mesh demister 11, which intercepts the mist droplets generated by the reaction. Then, it contacts the ammonia gas through cooling pipe 12. Water is supplied from water tank 28 and pressurized by water pump 29, causing the water in water tank 28 to flow outwards. The water flow is processed by condenser 30 to reduce its temperature before being introduced into cooling pipe 12 through inlet pipe 14. Under the action of water pump 29, the water continues to circulate, allowing cooling water to flow along cooling pipe 12 and cool the passing gas flow. This causes most of the ammonia gas to condense into ammonia water, which remains in purification tank 10, awaiting removal. At the same time, the temperature of the ordinary airflow is reduced so that it is discharged into the external space at a suitable temperature. The ammonia gas, after being condensed, finally comes into contact with the activated carbon adsorption layer 13. The activated carbon adsorption layer 13 further absorbs the ammonia concentration in the gas, making the discharged gas cleaner. When needed, the negative pressure fan 25 can be controlled to provide negative pressure to discharge the gas in the vessel 1 as much as possible. Moreover, the balancing air pipe 26 provides a ventilation structure. When the gas in the vessel 1 is discharged and the internal air pressure becomes low, the outside air is introduced into it through the balancing air pipe 26. The one-way valve 27 controls the gas in the vessel 1 to prevent the gas in the vessel 1 from being discharged from the balancing air pipe 26, thereby reducing the amount of ammonia gas remaining in the vessel 1.
