Description

Technical Field

[0001] The utility model belongs to the technical field of reaction kettles, in particular to a silver nitrate reaction kettle. Background Art

[0002] Silver nitrate is a colorless, transparent, orthorhombic flaky crystal. It is easily soluble in water and ammonia water, soluble in ether and glycerol, slightly soluble in anhydrous ethanol, and almost insoluble in concentrated nitric acid. Its aqueous solution is weakly acidic. The commonly used silver nitrate process principle is to rinse the silver with pure water, put it in a reactor, add an appropriate amount of deionized water, raise the temperature to a specified temperature, and gradually add nitric acid. In the reactor, silver reacts with nitric acid to form silver nitrate, and other metal impurities in the silver form nitrates. When the reaction of nitric acid and silver is completed, the temperature is raised to remove excess nitric acid, silver oxide is added to adjust the pH value, and an appropriate amount of deionized water is added to adjust the specific gravity of the silver nitrate solution. Other metal ions in the solution undergo a hydrolysis reaction with water to form a water-insoluble hydroxide precipitate. After filtration, the filtered silver nitrate solution enters an evaporation device for concentration, evaporation, crystallization, and drying to form a finished silver nitrate product.

[0003] Although the current reactor used for silver nitrate can meet the reaction requirements of silver and nitric acid, since the reaction of silver and nitric acid in the reactor will also generate precipitation, the precipitation will adhere to the side and bottom of the inner wall of the reactor, resulting in residues inside the reactor, which is inconvenient to clean.

[0022] In this embodiment, the reactor body 1 is used as the main reaction vessel for carrying the production process of silver nitrate. The feed pipe 2 is used to add the required raw materials, such as silver and nitric acid, into the reactor. The discharge pipe 3 is used to discharge the silver nitrate solution after the reaction. Two screws 4 are rotatably mounted on the reactor body 1 and are threadedly connected to the fixed block 6 on the scraper 5. This design enables the scraper 5 to move up and down along the inner wall of the reactor when the screw 4 rotates, effectively scraping off the sediment adhering to the side wall. The driving mechanism is used to drive the scraper to move up and down, and the movement of the scraper 5 is achieved by driving the rotation of the screw 4, so that the movement of the scraper is more stable and controllable, and the cleaning effect is improved. The cleaning mechanism is arranged at the bottom of the reactor body 1, and is used to scrape off the sediment at the bottom, and the bottom cleaning is achieved by the driving of the driving mechanism.

[0023] In a further preferred embodiment of the utility model, the driving mechanism includes two pulleys 7, a tensioner 8, a driving motor 9 and a driving belt 10, the two pulleys 7 are fixedly mounted on the two screws 4 respectively, the tensioner 8 is rotatably mounted on the top of the reactor body 1, the driving motor 9 is arranged on the reactor body 1, the output shaft of the driving motor 9 is fixedly connected to the tensioner 8, and the driving belt 10 is sleeved on the two pulleys 7 and the tensioner 8.

[0024] In this embodiment, two pulleys 7 are fixedly mounted on two screw rods 4, respectively. When the pulleys rotate, the screw rods 4 are driven to rotate together. The tensioner 8 is rotatably mounted on the top of the reactor body 1.

While driving the scraper 5 to move up and down, the driving mechanism can also drive the cleaning mechanism to clean the bottom of the reactor. This linkage design not only simplifies the operation process, but also improves the cleaning efficiency.

[0027] In a further preferred embodiment of the present invention, valves are provided on both the feed pipe 2 and the discharge pipe 3 .

[0028] In the present embodiment, the valve provided on the feed pipe 2 can control the entry of raw materials.

The presence of the protective cover 16 can also prevent people from accidentally touching the moving parts of the driving mechanism, reducing the safety risks during operation.

[0031] In a further preferred embodiment of the present invention, a slide groove 17 is provided on the reactor body 1 , a slider 18 is fixedly mounted on the scraper 5 , and the slider 18 is slidably mounted in the slide groove 17 .

[0032] In this embodiment, the opening position of the chute 17 matches the moving path of the scraper 5, ensuring that the slider 18 can slide smoothly in the chute 17. The fixed connection between the slider 18 and the scraper 5 ensures the stability and synchronization between the two, so that the scraper 5 can remain stable and accurate during the movement. The cooperation between the chute 17 and the slider 18 makes the movement of the scraper 5 more stable and controllable, and improves the cleaning effect and work efficiency.

[0034] In this embodiment, when the driving motor 9 is started, it drives the scraper 5 to move up and down along the chute 17 through the transmission action of the pulley 7, the driving belt 10 and the tensioning wheel 8 to complete the cleaning of the inner wall. At the same time, since the stirring shaft 19 is fixedly connected to the tensioning wheel 8, the stirring shaft 19 will also rotate accordingly. This rotational motion can effectively promote the mixing and reaction of the materials inside the reactor, improve the reaction efficiency and product quality. The rotational connection design between the stirring shaft 19 and the turntable 11 ensures that the stirring shaft 19 will not interfere with the work of the turntable 11 and the cleaning mechanism thereon when rotating. This ingenious linkage design allows the entire cleaning and stirring process to be carried out simultaneously without interfering with each other, thereby improving the working efficiency and practicality of the equipment.

[0035] In summary, compared with the relevant technology, the present device realizes the dual functions of efficient cleaning and uniform stirring of the silver nitrate reactor as a whole. Through the optimized design of the driving mechanism, not only the cleaning effect and working efficiency of the scraper on the inner wall of the reactor are improved, but also the linkage with the stirring shaft is realized, so that the material can be uniformly stirred at the same time during the cleaning process. In addition, the setting of the protective cover enhances the safety and stability of the equipment, while the coordination of the chute and the slider further improves the stability and controllability of the scraper movement.
