Description

Technical Field

[0001] This utility model relates to the chemical industry, and specifically discloses a rare earth chloride feeding device with a liquid level sensor. Background Technology

[0002] In rare earth chemical production, the rare earth chloride feeding device is one of the key pieces of equipment, its function being to accurately deliver the rare earth chloride solution to the designated process flow. However, existing feeding devices still have many shortcomings, affecting production efficiency and operational convenience.

[0003] Currently, most common rare earth chloride feeding devices on the market rely on manual observation of the liquid level and adjust the feed through manual or semi-automatic methods. This method has the following problems: First, since the detection of the liquid level depends on manual observation, errors are prone to occur, leading to overfeeding or underfeeding, affecting process stability; second, manual monitoring requires operators to be on duty for long periods, increasing labor intensity, and may also lead to inaccurate liquid level monitoring due to negligence or environmental factors.

[0004] Furthermore, existing feeding devices typically employ a fixed support structure, making it difficult to adjust the height according to different ground conditions after installation. This fixed structure design has limitations, especially when the ground is uneven or the installation position requires flexible adjustment. The equipment exhibits poor stability, is prone to swaying, and may even affect feeding accuracy. Existing concrete feeding devices for pipe pile forming (Publication No.: CN218227204U) have at least the following drawbacks:

[0005] 1. Existing feeding devices mostly rely on manual visual inspection to monitor the liquid level, requiring operators to periodically observe and manually adjust the feed rate. This method is easily affected by factors such as light and changes in liquid color, leading to misjudgments of the liquid level and impacting the stability of the feeding process. Because it depends on manual adjustment, negligence can easily result in insufficient or excessive feeding, thus affecting the continuity and stability of the rare earth production process. Therefore, there is an urgent need for a device that can monitor the liquid level without relying on manual inspection.

[0006] 2. Existing feeding devices typically use a fixed support structure, which cannot be adjusted in height after installation. When the equipment needs to be used in environments with different terrains or heights, the inability to adjust flexibly may lead to tilting or insufficient stability. When the ground is uneven, the fixed support of the equipment is prone to shaking, affecting feeding accuracy and even potentially damaging the equipment. Therefore, there is an urgent need for a height-adjustable device. Utility Model Content

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model incorporates a liquid level sensor installed inside the feeding device, enabling real-time monitoring of the liquid level without the need for manual visual inspection, thus avoiding misjudgments caused by factors such as light and changes in liquid color. The liquid level sensor is connected to the control system; when the liquid level falls below the set value, feeding is automatically initiated; when the liquid level reaches the upper limit, the feeding valve is automatically closed, ensuring the accuracy and stability of the feeding process. This design reduces the need for manual intervention, avoids insufficient or excessive feeding due to operator negligence, improves the continuity of rare earth production processes, and enhances production efficiency and safety.

[0016] 2. This utility model incorporates a telescopic support column at the bottom of the equipment, allowing for height adjustment to suit different installation ground conditions and adaptability to various terrains and production environments.

[0023] Example

[0024] Please see Figure 1-2 This utility model provides a technical solution:

[0025] A rare earth chloride feeding device with a liquid level sensor includes a feeding device body, a telescopic support column, and a liquid level sensor. The telescopic support column is installed at the bottom of the feeding device body, and a base plate is installed at the bottom of the telescopic support column. Limiting bolts are installed on the base plate. A filter plate is installed inside the feeding device body, and a liquid level sensor is installed on the filter plate. A siphon tank is located on the left side of the feeding device body, and a feeding conveying channel extends from the top of the siphon tank. The other end of the feeding conveying channel is connected to the top of the feeding device body. A fixing column is installed on the feeding conveying channel, and a control valve is installed on the fixing column. A feeding pump is located on the left side of the siphon tank, and a material suction pipe is installed above the feeding pump. A filter screen is installed at the top of the feeding conveying channel, and the filter screen is installed inside the feeding device body. A buoyancy box is installed above the filter screen, and a buoyancy ball is installed above the buoyancy box. An inlet pipe extends from the top of the feeding device body, and an inlet port is installed at the top of the inlet pipe.

[0026] It should be noted that automated liquid level monitoring is achieved through the linkage of the liquid level sensor and the control system, improving feeding accuracy and production stability. The liquid level sensor is installed on the filter plate, located inside the feeding device body, and monitors the liquid level in the feeding device in real time. When the liquid level is lower than the set value, the liquid level sensor sends a signal to the control system, which then starts the feeding pump to draw in the rare earth chloride solution through the material suction pipe and transport it to the siphon tank. The siphon tank guides the liquid into the feeding device body through the feeding conveying channel. A filter screen is installed at the inlet of this channel to filter out any solid impurities, ensuring the cleanliness of the feed. A control valve is connected to the top of the feeding conveying channel, which is installed on a fixed column to control the opening and closing of the feeding. When the liquid level sensor detects that the liquid level has reached the upper limit, the control system sends a command to the control valve to close the feeding channel, stop feeding, and prevent excessive liquid from entering.

[0027] The adaptability and stability of the equipment are improved through the cooperation of the telescopic support column, the base plate, and the limiting locking bolts: The bottom of the feeding device of this utility model is equipped with a telescopic support column. The height of this support column can be adjusted according to ground conditions, allowing the equipment to adapt to installation environments with different height requirements. The bottom of the telescopic support column is connected to the base plate, providing a stable support foundation and ensuring the overall stability of the equipment. Limiting locking bolts are installed on the base plate to fix the height of the support column. After adjusting the height of the support column, tightening the limiting locking bolts locks the telescopic support column, preventing changes in height or tilting of the equipment due to vibration or uneven ground. This structure allows operators to adjust the equipment height according to different terrains or usage scenarios, ensuring the equipment remains stable and preventing shaking caused by tilted or uneven ground, which could affect feeding accuracy.

[0028] Optimized feeding conveyor structure improves feeding smoothness: The feeding conveyor channel adopts a siphon design, used in conjunction with a siphon tank, to make material flow more stable and reduce liquid backflow. A filter screen installed inside the feeding channel effectively removes solid particles from the material, preventing blockage of the conveying pipe and improving feeding smoothness. A combination of a buoyancy box and buoyancy ball is used; when the liquid reaches a certain level, the buoyancy ball automatically rises, assisting in liquid level control and preventing excessive liquid from entering the feeding device. A liquid inlet pipe is located at the top of the equipment, with an inlet port at the top, providing an additional liquid replenishment channel to accommodate different feeding needs.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
