Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyanide reaction vessel technology, and in particular to a self-cleaning cyanide reaction circulation device. Background Technology
[0002] Cyanide reaction is widely used in fields such as precious metal extraction and organic synthesis. During the reaction process, a cyanide reaction recycling vessel is required, mainly to achieve full mixing, reaction and recycling of cyanide and raw materials.
[0003] The prior art patent document CN222093337U discloses a hydrocyanation reactor, including a reactor body, a hollow stirring shaft and a gas distributor inside the reactor body, the gas distributor being connected to a gaseous HCN gas source. The hollow stirring shaft and the gas distributor work together to mix the materials inside the reactor body. The reactor body is provided with a first discharge port and a reflux port. The reflux port is connected to a heat exchanger, and the first discharge port is connected to an external circulation pump. The heat exchanger and the external circulation pump are interconnected. An overflow baffle is provided at the first discharge port inside the reactor body, which can make the gas-liquid mixture in the reactor more uniform and effectively improve the reaction efficiency. The overflow baffle can achieve the effect of gas-liquid separation, which can effectively prevent gaseous substances from entering the external circulation pump with liquid substances and causing cavitation. The external heat exchanger can remove the heat generated by the hydrocyanation reaction, which can effectively avoid the problem of excessive side reactions caused by local overheating.
[0004] However, according to the existing patent document CN222093337U, the existing cyanidation reaction equipment requires periodic shutdown for disassembly and cleaning, which is difficult to clean, affects production efficiency, and is not convenient to meet the usage requirements.
[0005] Therefore, we propose a self-cleaning cyanide reaction cycle device. Utility Model Content

The air compressor facilitates the use of compressed air to blow away residual liquid inside the nozzle, preventing crystallization and solidification that could clog the nozzle orifice, thus reducing cleaning difficulty and improving production efficiency.
[0017] This invention, through the installation of a scraper and a polytetrafluoroethylene coating, allows the scraper to easily remove stubborn scale from the inner wall of the cyanide reaction circulating vessel, while the polytetrafluoroethylene coating helps prevent materials from adhering to the inner wall of the cyanide reaction circulating vessel and has excellent resistance to cyanide, with no swelling or corrosion even after long-term immersion, thus extending its service life.

[0027] Example: A self-cleaning cyanide reaction recycling device, such as Figures 1-5 As shown, the system includes a base plate 1, a support frame 2 fixedly installed at the top of the base plate 1, a cyanide reaction circulation vessel 3 fixedly installed in the middle of the support frame 2, a cleaning liquid tank 4 fixedly installed on one side of the top of the base plate 1 away from the cyanide reaction circulation vessel 3, an air compressor 5 fixedly installed on one side of the top of the base plate 1 near the cleaning liquid tank 4, a geared motor 6 fixedly installed at the top of the cyanide reaction circulation vessel 3, a rotating disk 7 fixedly installed inside the cyanide reaction circulation vessel 3 extending from the output shaft end of the geared motor 6, and a mounting column 8 fixedly installed at the bottom end of the rotating disk 7, a rotary joint 9 installed at the outer end of the mounting column 8, and a nozzle 10 fixedly installed at the outer end of the mounting column 8 to facilitate the rotation of the nozzle 10 to thoroughly rinse the inside of the cyanide reaction circulation vessel 3. After rinsing, the compressed air from the air compressor 5 enters the liquid inlet pipe 12 through the air inlet pipe 15 and is discharged from the nozzle 10 to blow away residual liquid and prevent crystallization and solidification that could clog the nozzle.
[0028] like Figures 1-5As shown, a water pump 11 is fixedly installed on one side of the cleaning liquid tank 4, and an inlet pipe 12 is fixedly installed on one side of the water pump 11. The inlet pipe 12 extends into the interior of the cyanide reaction circulating vessel 3. The inlet pipe 12 is fixedly connected to a rotary joint 9, and a solenoid valve 13 is fixedly installed at the outer end of the inlet pipe 12. An exhaust valve 14 is fixedly installed on one side of the top of the cyanide reaction circulating vessel 3. An air inlet pipe 15 is fixedly installed on the top of the air compressor 5. The air inlet pipe 15 is fixedly connected to the inlet pipe 12, and a solenoid valve 16 is fixedly installed at the outer end of the air inlet pipe 15. A stirring motor 17 is fixedly installed at the bottom of the cyanide reaction circulating vessel 3. The output shaft of the stirring motor 17 extends into the interior of the cyanide reaction circulating vessel 3, and a stirring rod 19 is fixedly installed at the output shaft of the stirring motor 17.

During the rotation of the stirring rod 19, the scraper 20 also rotates to remove stubborn scale from the inner wall of the cyanide reaction circulation vessel 3. The polytetrafluoroethylene coating 21 applied to the inner wall of the cyanide reaction circulation vessel 3 adheres almost no liquid or solid, allowing the cyanide solution to flow away quickly, preventing crystallization and deposition. It also exhibits excellent tolerance to cyanide, allowing for long-term immersion... After the reaction is complete and there is no swelling or corrosion, open solenoid valve 13 and close solenoid valve 2. Water pump 11 pumps the cleaning liquid in cleaning liquid tank 4 into cyanide reaction circulating kettle 3 through inlet pipe 12. Inlet pipe 12 is connected to rotary joint 9. Gear motor 6 drives rotating disk 7 to rotate. Rotating disk 7 drives nozzle 10 to rotate through mounting column 8 to thoroughly rinse the inside of cyanide reaction circulating kettle 3. After rinsing, solenoid valve 13 is closed and solenoid valve 2 is opened. Air compressor 5 compresses air and enters inlet pipe 12 through air inlet pipe 15 and is discharged from nozzle 10 to blow away residual liquid and prevent crystallization and solidification from clogging the nozzle.
