Description

Technical Field

[0001] This utility model relates to the field of metal metallurgy, and in particular to an oxidation-enhanced hydrometallurgical equipment for sodium pyroantimonate. Background Technology

[0002] Oxidation-enhanced sodium pyroantimonate hydrometallurgical equipment refers to a specialized equipment system for producing sodium pyroantimonate through an oxidation-enhanced hydrometallurgical process. Hydrometallurgy is a method of extracting or purifying metals through chemical reactions, typically requiring the addition of oxidizing and reducing agents to separate the desired metal from ore or waste. Oxidation enhancement refers to the process of adding oxidizing agents (such as hydrogen peroxide) or increasing oxidation conditions during hydrometallurgy to more effectively oxidize the antimony element in the raw materials, thereby generating the desired sodium pyroantimonate. The process flow of oxidation-enhanced sodium pyroantimonate hydrometallurgical mainly involves raw material processing, oxidation reaction, neutralization precipitation, and subsequent treatment.

[0003] In the traditional oxidative-enhanced hydrometallurgical process of sodium pyroantimonate, the method of adding the oxidant (such as hydrogen peroxide) is a critical step, directly affecting the distribution of the oxidant in the reaction equipment and the subsequent reaction rate and efficiency. Usually, the oxidant is added to the reaction equipment dropwise. Dropwise addition ensures that the oxidant gradually enters the reaction system at a certain rate and amount, thus avoiding the problem of excessively high or low local concentrations caused by adding it all at once. However, dropwise addition cannot guarantee the uniform distribution of the oxidant. If the dropwise addition position is improper or the dropwise speed is too fast, it may lead to uneven distribution of the oxidant in the reaction equipment, thereby limiting the reaction efficiency.

[0004] Therefore, in view of the above situation, there is an urgent need to develop an oxidation-enhanced sodium pyroantimonate hydrometallurgical equipment to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide an oxidation-enhanced sodium pyroantimonate hydrometallurgical equipment, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The reaction chamber is fixedly connected to the upper end of the base frame, and the top cover is hinged to the upper end of the reaction chamber. An inlet pipe is provided on the top cover for injecting an oxidant into the reaction chamber.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figure 1-4As shown in the figure, this utility model embodiment provides an oxidatively enhanced sodium pyroantimonate hydrometallurgical equipment, including a base frame 1, a reaction chamber 2, and a top cover 3. The reaction chamber 2 is fixedly connected to the upper end of the base frame 1, and the top cover 3 is hinged to the upper end of the reaction chamber 2. The top cover 3 is provided with a liquid inlet pipe 12, which is used to inject an oxidant into the reaction chamber 2. A dispersion component 5 is provided inside the reaction chamber 2 to disperse the oxidant injected from the liquid inlet pipe 12. A stirring device 6 is provided at the bottom of the reaction chamber 2 to stir and mix the raw materials and the oxidant. The outer wall of the reaction chamber 2 is wrapped with a water-proof shell 4, and the cavity between the reaction chamber 2 and the water-proof shell 4 is filled with a coolant. A temperature control component 11 is connected to the water-proof shell 4 to control the temperature of the coolant inside the water-proof shell 4, thereby controlling the temperature of the environment in which the oxidant and raw materials react inside the reaction chamber 2.

[0025] It is understood that the mixing equipment 6 adopts existing technology, which will not be described in detail here.

[0026] Furthermore, water was chosen as the coolant.

[0027] Furthermore, a second fixing ring 7 is fixedly sleeved on the stirring shaft of the stirring device 6. A plurality of axially evenly distributed support plates 8 are fixedly connected to the outer wall of the second fixing ring 7. Each support plate 8 is fixedly connected to a scraper 9, and the scraper 9 abuts against the inner wall of the reaction tank 2. The scraper 9 is used to scrape off the material attached to the inner wall of the reaction tank 2.

[0028] Specifically, the raw materials are added to the reaction chamber 2 by opening the top cover 3, and the oxidant is injected into the reaction chamber 2 through the liquid inlet pipe 12. The injected oxidant is dispersed by the dispersion component 5, so that it is evenly distributed on the raw materials. The raw materials and oxidant are mixed by the stirring device 6, so that they are evenly distributed, thereby improving the reaction efficiency. The material adhering to the inner wall of the reaction chamber 2 is scraped off by the scraper 9, and the temperature control component 11 is used to control the temperature of the coolant in the water-proof shell 4, thereby controlling the temperature of the environment in which the oxidant and raw materials react in the reaction chamber 2.

[0029] like Figure 1-3 As shown, the dispersion component 5 includes a motor 51, a dispersion shaft 52, a first fixing ring 53, and dispersion plates 54; the motor 51 is fixedly connected to the top cover 3, the drive shaft of the motor 51 passes through the top cover 3 and is fixedly connected to the dispersion shaft 52, the lower end of the dispersion shaft 52 is fixedly connected to the first fixing ring 53, and a plurality of evenly distributed dispersion plates 54 are rotatably connected to the first fixing ring 53.

[0030] Furthermore, the dispersion plate 54 is provided with a dispersion slope foot 541, which makes the upper end of the dispersion plate 54 wider than the lower end, so that when the side with the dispersion slope foot 541 impacts the oxidant, the oxidant is dispersed in the downward direction.

[0031] Furthermore, the height of the dispersion plate 54 is greater than its width, which allows the side of the dispersion ramp foot 541 to have a larger contact area with the oxidant injected from the liquid inlet pipe 12, thereby enabling more oxidant to come into contact with and impact, resulting in more uniform dispersion of the oxidant.

[0032] Understandably, motor 51 needs to be set to a suitable speed. If the speed is too high, the wind speed generated by motor 51 may blow the falling oxidant out along the liquid inlet pipe 12.

[0033] Specifically, the motor 51 starts, and then the motor 51 drives the dispersing shaft 52 to rotate through the drive shaft. Then the dispersing shaft 52 drives the first fixing ring 53 to rotate around the dispersing shaft 52. Subsequently, the first fixing ring 53 drives the dispersing plate 54 to rotate around the dispersing shaft 52, thereby impacting the falling oxidant and dispersing it downward.

[0034] like Figure 1 and Figure 2 As shown, the temperature control assembly 11 includes an inlet pipe 1101, a water pump 1102, an outlet pipe 1103, a water tank 1104, a temperature control device 1105, and an intermediate pipe 1106; the inlet pipe 1101 and the water pump 1102 are fixedly connected to the outer wall of the water-proof shell 4; the outlet end of the water pump 1102 is fixedly connected to the inlet pipe 1101, the inlet end of the water pump 1102 is fixedly connected to the intermediate pipe 1106, the other end of the intermediate pipe 1106 is fixedly connected to the water tank 1104, and the water tank 1104 and the outlet pipe 1103 are connected in series; the temperature control device 1105 is also connected to the water tank 1104; a temperature sensor is also fixedly connected to the outer wall of the reaction chamber 2.

[0035] Specifically, the water in the cavity between the reaction chamber 2 and the water-proof shell 4 enters the water tank 1104 through the outlet pipe 1103, then enters the water pump 1102 through the intermediate pipe 1106, and then returns to the cavity between the reaction chamber 2 and the water-proof shell 4 through the inlet pipe 1101. During this process, the temperature control device 1105 adjusts the water temperature in the water tank 1104 according to the temperature detected by the temperature sensor, thereby controlling the water temperature in the cavity between the reaction chamber 2 and the water-proof shell 4, and thus controlling the temperature in the reaction chamber 2 to be within a suitable range for the reaction of the oxidant and the raw materials.

[0036] The working principle of this utility model is as follows: Raw materials are added to the reaction chamber 2 by opening the top cover 3. The motor 51 starts, and then the motor 51 drives the dispersing shaft 52 to rotate via the drive shaft. The dispersing shaft 52 then drives the first fixing ring 53 to rotate around the dispersing shaft 52. Subsequently, the first fixing ring 53 drives the dispersing plate 54 to rotate around the dispersing shaft 52. Then, oxidant is injected into the reaction chamber 2 through the liquid inlet pipe 12. The dispersing plate 54 impacts the falling oxidant, causing it to disperse downwards. The stirring device 6 stirs and mixes the raw materials and oxidant, and drives the second fixing ring 7 to rotate. The second fixing ring 7 then drives the scraper via the support plate 8. 9. The movement scrapes away the material adhering to the inner wall of the reaction chamber 2. In addition, the water in the cavity between the reaction chamber 2 and the water-proof shell 4 enters the water tank 1104 through the water outlet pipe 1103, then enters the water pump 1102 through the intermediate pipe 1106, and then returns to the cavity between the reaction chamber 2 and the water-proof shell 4 through the water inlet pipe 1101. During this process, the temperature control device 1105 adjusts the water temperature in the water tank 1104 according to the temperature detected by the temperature sensor, thereby controlling the water temperature in the cavity between the reaction chamber 2 and the water-proof shell 4, and thus controlling the temperature in the reaction chamber 2 to be within the range suitable for the reaction of oxidant and raw materials.

[0037] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
