[0002] Accurate liquid level measurement during the storage, transportation, and processing of slurry can prevent slurry overflow from containers, avoiding material waste, environmental pollution, and potential safety accidents. It also prevents equipment from running dry without slurry, preventing equipment damage and ensuring the continuity of the production process. Real-time liquid level monitoring allows for precise control of slurry inflow and outflow, maintaining a balance between material supply and consumption during production, ensuring stable operation of the production system, and improving production efficiency and product quality.

The drip head 10 is located inside the collection frame 14.
[0037] During testing, a clean water pipe 4 is connected via an external water pipe, allowing water to enter the connecting pipe 6. As the water flows through the clean water flow stabilizer 5, the flow rate is controlled to ensure stable water flow. The clean water flow stabilizer 5 provides unidirectional flow, reducing slurry backflow. The stable water flow enters the connecting pipe 6, then the pressure guiding pipe 7, and finally the connecting pipe 22. The water then enters the isolation pipe 8. This provides a clean testing environment for the sensor detection head, facilitating stable sensor operation and cleaning. Simultaneously, water flows through... The pressure guide pipe 7 enters the sleeve 9, forming a dynamic pressure balance of water. Some clean water flows out through the drip head 10, and then the controller 3 activates the electric expansion joint 11. The expansion joint 11 extends and retracts, causing the telescopic steel wire 12 to extend and retract, removing the clumps attached to the drip head 10.

The arc-shaped contact plate 19 releases its contact with the fixed column 16, allowing the sliding sleeve 18 to slide on the fixed column 16. The testing equipment is adjusted to the specified depth, and the scale strip 21 facilitates precise positioning of the testing equipment.

[0040] The implementation principle of the online detection device for measuring the liquid level of easily adhering slurry in this embodiment is as follows: During detection, the operator installs the hydraulic sensor body 1 at a suitable depth of the slurry to be detected.

The controller 3 displays the value of the hydraulic sensor body 1 for easy observation by the operator. The sensor detection head is protected by the isolation tube 8.
[0041] During testing, a clean water pipe 4 is connected to an external water pipe, allowing water to enter the connecting pipe 6. As the water flows through the clean water flow stabilizer 5, the stabilizing head controls the incoming water flow to ensure stable water entry. The stabilizing head 5 has a unidirectional flow function, reducing slurry backflow. The stable water flow enters the connecting pipe 6, then the pressure guiding pipe 7, and finally the connecting pipe 22. The water then enters the isolation pipe 8, providing a clean testing environment for the sensor detection head, facilitating stable sensor operation and cleaning. Simultaneously, water enters the sleeve 9 through the pressure guiding pipe 7, creating a dynamic pressure balance. Some clean water flows out through the drip head 10, and the controller 3 activates the electric telescopic device 11. The telescopic device 11 extends and retracts, causing the telescopic steel wire 12 to extend and retract, removing the clumps attached to the drip head 10. This causes the steel wire to drive the brush to move, improving the cleaning effect on the drip head 10. The clumps are collected through the collection frame 14 and the filter screen 15.
[0042] During testing, the staff uses the fixed column 16 to facilitate the insertion of the testing equipment into the slurry of the testing tank. During testing, the fixed sleeve 20 is turned, causing it to rotate and move on the arc-shaped contact plate 19. The arc-shaped contact plate 19 releases its contact with the fixed column 16, allowing the sliding sleeve 18 to slide on the fixed column 16. The testing equipment is adjusted to the specified depth, and the scale strip 21 facilitates precise positioning of the testing equipment.
