Technical Field
[0001] The utility model relates to the field of conveying devices, in particular to a rare earth liquid conveying device. Background Art
[0002] Rare earth elements were discovered in the late 18th century. At that time, people often called water-insoluble solid oxides earth. Rare earths are generally separated in the form of oxides. Although the reserves on the earth are very huge, it is difficult to smelt and purify them, so they are relatively rare, hence the name rare earths. Generally speaking, rare earths on the earth exist in the form of rare earth oxides. Rare earths are known as "industrial vitamins". Today, they have become an extremely important strategic resource. When transporting rare earth liquid, a conveying device is needed to transport it.
[0003] In the production process of rare earth materials, the conveying link is the key link connecting raw material storage and processing procedures. Traditional conveying devices usually rely on simple pumping or gravity to convey materials, which have a series of limitations in design and operation. In traditional systems, since the output pressure of the pump is difficult to accurately control, the material flow rate and pressure fluctuate during the actual conveying process, which in turn affects the quality and production efficiency of the materials. In addition, when production conditions change, traditional systems lack the ability to flexibly adjust and are difficult to adapt to these changes in real time, thus affecting the stability of the production process.
[0004] Therefore, the existing rare earth material conveying systems mentioned above often cannot achieve precise pressure and flow control, lack the ability to flexibly adjust, and are difficult to adapt to these changes in real time, thus affecting the stability of the production process. A rare earth liquid conveying device can be designed to improve the above problems, so as to achieve precise control of pressure and flow during the rare earth material conveying process by stabilizing the front-end pressure and introducing closed-loop control logic, ensuring the stability of the conveying process and meeting specific production needs. Through the dynamic adjustment mechanism, the system can automatically adjust according to real-time production conditions to adapt to different production environments and material characteristics, and ensure the continuity and stability of the production process. Utility Model Content
[0005] In order to overcome the relatively low control accuracy and response speed in traditional conveying devices, most of them rely on variable frequency pumps and basic pressure feedback mechanisms. Due to the simple control strategy, the response to sudden pressure or flow changes is slow, and it is difficult to achieve precise control. At the same time, due to the lack of system stability and reliability, as well as the low degree of automation, maintenance is frequent and operation is complicated, which increases maintenance and operating costs. Therefore, traditional conveying systems usually rely on simple pumping systems or gravity to convey materials. These systems have a series of limitations and shortcomings in design and operation.

[0007] Preferably, a material storage component is provided for material storage, and an internal scraping structure is provided to facilitate scraping the inner wall of the material storage component to prevent rare earth adhesion; a flow monitoring component is provided for flow monitoring to facilitate detection sensing.
[0008] Preferably, a large gear is meshed and rotated on one side of the small gear; a rotating connecting frame is provided at the upper end of the large gear; and a rotating scraper is provided at the lower end of the rotating connecting frame. The pipeline connects the various components to provide a conveying channel for the rare earth material. The control unit receives data from the detection unit and automatically adjusts the operating status of the circulation pump and the constant pressure pump according to a preset program to achieve closed-loop control. The detection unit includes a pressure sensor and a flow sensor, which monitors the pressure and flow data in the conveying pipeline in real time and feeds the data back to the control unit.
[0009] Preferably, an annular bracket is arranged outside the silo; an output pipeline is arranged at the lower end of the silo. The silo is used to store the rare earth material to be transported. The circulation pump transports the rare earth material in the silo to the pressure stabilizing box.
[0010] Preferably, a circulation pump is provided on one side of the output pipeline, and the circulation pump adopts variable frequency control to adjust the flow rate, which is more energy-saving and efficient.
[0011] Preferably, a pressure inlet pipe is provided on one side of the circulation pump; a valve is provided on the pressure inlet pipe; a pressure stabilizing box is provided outside the pressure inlet pipe; a column bracket is provided at the lower end of the pressure stabilizing box; and a return pipe is provided at the rear end of the pressure stabilizing box. The pressure stabilizing box is located between the circulation pump and the constant pressure pump, and plays a role in buffering and stabilizing pressure.
[0012] Preferably, a double-ended feed pipe is provided on one side of the pressure stabilizing box; a filter box is provided on one side of the double-ended feed pipe; a flip cover is provided on the upper end of the filter box; a detachable filter plate is provided inside the filter box; a rotatable connector is rotatably connected between the flip cover and the detachable filter plate; and a double-ended discharge pipe is provided on one side of the filter box.

The speed of the constant pressure pump can be automatically adjusted by the control system to adapt to different pressure requirements.
[0014] Beneficial effects of the utility model:
[0015] 1. By setting up a pressure and flow monitoring system, after it is started, the detection unit monitors the pressure and flow in the conveying pipeline in real time and sends the data to the control unit. The pressure regulation is calculated by the control unit based on the received data and the built-in algorithm to calculate the required pump speed adjustment. When the monitored pressure is lower than the set value, the control unit will increase the speed of the constant pressure pump; otherwise, it will reduce the speed to maintain the set pressure value. The closed-loop control continuously receives data feedback from the detection unit through the control unit, and continuously adjusts the speed of the constant pressure pump to form a closed-loop control system to ensure the stability of the pressure during the conveying process. The use of front-end stabilization measures and closed-loop control systems can monitor the pressure and flow in the conveying pipeline in real time and make rapid adjustments. The system uses highly sensitive sensors and powerful control units to accurately control pressure and flow, with fast response speed and strong stability. It improves the stability and reliability of the system and reduces downtime and maintenance costs caused by frequent manual adjustments and maintenance. At the same time, the simplified operation process reduces the skill requirements for operators and further reduces labor costs. It overcomes the relatively low control accuracy and response speed in traditional conveying devices, which mostly rely on variable frequency pumps and basic pressure feedback mechanisms. Due to the simple control strategy, the response to sudden pressure or flow changes is slow, making it difficult to achieve precise control. At the same time, due to the lack of system stability and reliability, as well as the low degree of automation, maintenance is frequent and operation is complicated, which increases maintenance and operating costs. Therefore, traditional conveying systems usually rely on simple pumping systems or gravity to convey materials. These systems have a series of limitations and shortcomings in design and operation;

The circulation pump adopts variable frequency control to adjust the flow rate, which is more energy-saving and efficient. Pipes connect various components to provide a transportation channel for rare earth materials. The pressure regulating box is located between the circulation pump and the constant pressure pump, which plays a role in buffering and stabilizing the pressure. The filter unit is installed in an appropriate position to filter impurities that may be contained in the raw materials, protect downstream equipment and improve product quality.
