By adjusting the liquid level, not only can the whole system achieve dynamic balance, but also the equipment of the vortex well can be protected from being flooded. Accurate monitoring of its liquid level is of key significance for the stable operation of the entire production process. The vortex well is usually used to treat a large amount of industrial wastewater, slurry, etc., and the internal environment is complex and harsh. As a key equipment for measuring the liquid level of the vortex well, the liquid level meter faces many challenges.

The detachable connection facilitates the installation and maintenance of the liquid level meter.

[0026] In a preferred scheme of the present embodiment, the liquid inlet 4 is a semicircular structure with an opening facing downward. The design of the liquid inlet 4 with a semicircular structure and an opening facing downward facilitates the rapid inflow of water into the protective tube body 3, so that the liquid level in the protective tube body 3 can timely and accurately reflect the liquid level height of the liquid in the inner ring 2, thereby improving the accuracy and timeliness of the liquid level measurement.

[0027] In a preferred solution of the present embodiment, the protective tube body 3 is made of a 10-meter steel pipe of DN80. The protective tube body 3 is made of a 10-meter steel pipe of DN80, which has certain strength and stability and can withstand the pressure and water flow impact in the vortex well 1, thereby ensuring the reliability of the protective tube body 3 during use.

[0028] In a preferred solution of the present embodiment, a plurality of first through holes are arranged in the vertical direction of the protective tube body 3. The plurality of first through holes can ensure the pressure balance inside and outside the protective tube body 3, avoid inaccurate liquid level measurement due to pressure difference, and also help the liquid level meter to sense liquid level changes more sensitively.

[0029] In a preferred solution of the present embodiment, the first through holes are arranged at intervals of 1 meter in the vertical direction. The first through holes are arranged at intervals of 1 meter, so that the pressure balance and liquid level sensing are more uniform, thereby improving the accuracy and stability of liquid level measurement.

The second through holes are horizontally arranged corresponding to the first through holes, which further enhances the pressure balance effect inside and outside the protection tube body 3. The circular hole design with a diameter of 8 mm can meet the pressure balance requirements without causing excessive impact on the structural strength of the protection tube body 3.

[0031] In a preferred scheme of the present embodiment, the vortex well liquid level gauge protection device also includes a first indication hole 6, a second indication hole 7, a third indication hole 8 and a fourth indication hole 9. The first indication hole 6, the second indication hole 7, the third indication hole 8 and the fourth indication hole 9 are arranged in the vertical direction of the protection tube body 3, and the outer wall of the protection tube body 3 is provided with scale lines in the vertical direction. When the first indication hole 6, the second indication hole 7, the third indication hole 8 and the fourth indication hole 9 can indicate the scale lines, preferably, when the liquid level is in the fourth indication hole 9, it is a low-low alarm, when the liquid level is in the third indication hole 8, it is a low alarm, when the liquid level is in the second indication hole 7, it is a high alarm, and when the liquid level is in the first indication hole 6, it is a high-high alarm. The setting of each indication hole and scale lines makes the reading of the liquid level more intuitive and accurate, which is convenient for the operator to quickly understand the liquid level situation and improve work efficiency.

[0032] In a preferred solution of the present embodiment, the vortex well liquid level gauge protection device also includes a first sealing plate, which is arranged at the top of the protection tube body 3. The first sealing plate is provided with a threaded hole, which is used for threaded connection with the liquid level gauge. The setting of the first sealing plate provides a stable installation position for the liquid level gauge. The threaded connection method is firm and reliable, and is easy to install and disassemble, thereby ensuring the stability of the liquid level gauge in the protection tube body 3.

[0033] In a preferred scheme of this embodiment, the surface of the protective tube body 3 is provided with an anti-corrosion coating, which can effectively resist the erosion of the protective tube body 3 by the corrosive medium in the vortex well 1, extend the service life of the protective tube body 3, and thus provide long-term and stable protection for the liquid level meter.
