Description

Technical Field

[0001] The utility model relates to the field of chemical industry, in particular to a device for stirring and mixing rare earth concentrate and hydrochloric acid. Background Art

[0002] The current rare earth concentrate stirring and mixing device has low safety. The processed materials will be spilled during stirring. In case of emergency, there is no emergency stop function. There is no temperature monitoring function. It is not easy to monitor the production temperature during production, which leads to the product quality being affected by temperature problems. There is no intelligent control. Due to the high cost of rare earth materials, manual real-time monitoring is required during chemical processing, which increases the labor cost. The existing extraction stirring mechanism of a rare earth processing extraction device (Announcement No.: CN219149307U) has at least the following disadvantages in use:

[0003] 1. The current rare earth concentrate stirring and mixing device has potential safety hazards. The stirring process may cause the processed materials to leak, and there is no emergency stop function in an emergency. In this case, once an accident occurs, both the operator and the equipment may be damaged, so a highly safe rare earth concentrate and hydrochloric acid stirring and mixing device is urgently needed;

[0004] 2. The lack of temperature monitoring function during the production process makes it difficult to accurately monitor the production temperature, which may have a negative impact on the quality of the final product. Temperature is a critical parameter in many chemical processes. It directly affects key indicators such as reaction rate, product purity and yield. Therefore, a rare earth concentrate and hydrochloric acid stirring and mixing device that can monitor temperature is urgently needed;

[0005] 3. The lack of intelligent control function may lead to the need for manual real-time monitoring during the rare earth chemical processing, which increases labor costs. The cost of rare earth materials is high, so in the chemical processing process, the realization of intelligent control can improve the efficiency and stability of the operation and reduce the need for manual monitoring. Therefore, a rare earth concentrate and hydrochloric acid stirring and mixing device that can perform intelligent control is urgently needed. Utility Model Content

[0006] The main purpose of the utility model is to provide a rare earth concentrate and hydrochloric acid stirring and mixing device, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A device for stirring and mixing rare earth concentrate and hydrochloric acid comprises a mixer tank body, a mixing tank bracket is installed below the mixer tank body, a mixing controller is installed outside the mixer tank body, a mixer safety shield is covered above the mixer tank body, a mixing temperature sensor is installed below the mixer tank body, the mixer safety shield is rotated by a shield rotating shaft arranged on the side of the mixer tank body, a hydrochloric acid storage box is arranged above the mixer tank body, and a rare earth storage box is installed on the left side of the hydrochloric acid storage box. A hydrochloric acid spray head is installed below the hydrochloric acid storage box. A storage box bracket is installed on the right side of the hydrochloric acid storage box. A storage box bracket is installed on the left side of the rare earth storage box. A mixing and stirring fan blade is installed inside the mixer tank body. The mixing and stirring fan blade is connected to the stirring shaft motor.

[0009] Preferably, a hydrochloric acid storage box is provided above the mixer tank.

[0010] Preferably, a rare earth storage box is installed on the left side of the hydrochloric acid storage box.

[0011] Preferably, a hydrochloric acid spray head is installed below the hydrochloric acid storage box.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model adds a mixer safety shield and a mixing controller. When the mixing is performed after the addition, the shield is closed to prevent the corrosion damage caused by the leakage of hydrochloric acid. When the equipment is abnormal, the controller controls the equipment to stop urgently to ensure the safety of the operator and the equipment.

[0014] 2. By installing a mixing temperature sensor and a mixing controller, the temperature inside the mixer is monitored. When the temperature is too high, the sensor sends an electrical signal to the controller, thereby reducing the addition of hydrochloric acid and lowering the stirring rate, solving the production danger and low product quality problems caused by excessive temperature;

[0015] 3. By using hybrid controllers to perform intelligent control of equipment, production problems caused by inadequate manual monitoring can be avoided, production efficiency and stability can be improved, and labor costs can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Traditional processing 1 Traditional processing 2 Traditional processing 3 New processing Product quality 70％ 75％ 60％ 85％ Production efficiency 60％ 74％ 73％ 95％ Labor costs 94％ 90％ 95％ 80％

[0028] In this embodiment, the mixed temperature sensor 12 uses the TD Series temperature sensor produced by Honeywell. Compared with the new equipment using this sensor in the above figure, the product quality has increased by 10% to 25%, which greatly improves the product quality. It has many advantages. For example, the TD Series temperature sensor has high-precision measurement capabilities and can provide reliable and accurate temperature data. This series of sensors is designed to work in high-temperature environments and has good high-temperature resistance. For harsh environments such as chemical monitoring, corrosion-resistant materials are usually used in TD Series sensors to ensure the long-term stable operation of the sensor in corrosive media. As a well-known manufacturer, Honeywell's products usually have high reliability and stability, and TD Series sensors are no exception. TD Series provides a variety of models and options to meet the needs of different chemical monitoring scenarios, such as different measurement ranges, output signal types, etc.

[0029] In this embodiment, the hybrid controller 4 uses the DOP Series HMI industrial controller produced by Delta Electronics. As shown in the comparison data in the above table, the production efficiency is improved by 10% to 25% and the labor cost is reduced by 6% to 10%. It also has many advantages, such as the DOP Series HMI uses a touch screen operation interface, making the operation more intuitive and convenient. Users can achieve control and monitoring functions through simple finger touch and gesture operation. As a well-known industrial automation solution provider, Delta Electronics' products have reliable performance and stability. The DOP Series HMI has undergone strict quality control and testing, adapts to harsh industrial environments, and can operate stably for a long time. The DOP Series HMI provides a variety of options with different sizes, resolutions and functional configurations to meet different application requirements. Users can choose a suitable model according to specific project requirements. The DOP Series HMI has rich functions and flexible customization options, which can realize data visualization, real-time monitoring, alarm processing and other functions. It supports a variety of communication interfaces and protocols, which is convenient for connection and integration with other devices.

[0030] It should be noted that the utility model adds a safety shield and a mixing controller to the mixer. When stirring after the addition is completed, the shield is closed to prevent corrosive damage caused by hydrochloric acid leakage. When the equipment is abnormal, the controller urgently controls the equipment to stop urgently to ensure the safety of the operator and the equipment. By adding a mixing temperature sensor and a mixing controller, the temperature inside the mixer is monitored. When the temperature is too high, the sensor transmits an electrical signal to the controller, thereby reducing the addition of hydrochloric acid and reducing the stirring rate, solving the production danger and low product quality problems caused by excessive temperature. By using a mixing controller for intelligent control of the equipment, production problems caused by inadequate manual monitoring are avoided, production efficiency and stability are improved, and labor costs are reduced.
