The opening of the emptying pipe is facing downwards, which can prevent sundries or rainwater from entering the measuring pipe of the level gauge from the closing of the emptying pipe. The flushing water is connected to the outlet of the vent pipe, and the drain valve is opened, and the liquid level gauge can be regularly backwashed to prevent the ammonium sulfate slurry from scaling in the measuring pipe.

The utility model has the following beneficial effects through the above-mentioned technical solutions:

The utility model is a single-flange side-mounted liquid level measuring device, the top of the measuring device is provided with an anti-air pipe, which is suitable for the liquid level measuring device of the desulfurization circulation tank working condition, and can display the liquid level of the desulfurization circulation tank intuitively and accurately. The operator can compare the local liquid level and the remote liquid level. When the remote liquid level gauge has a fault or abnormal indication, the remote liquid level gauge is repaired based on the local liquid level indication. The purpose of intuitive and accurate measurement of the on-site liquid level of the desulfurization circulating tank and easy maintenance is realized.

Detailed ways

As shown in Figure 1, a desulfurization circulating tank liquid level measuring device includes a downward facing pipe (overflow port) 2, a scale 3, a measuring pipe 4, a flange 6, a sewage valve 7, an upper hoop Fixing point 2, lower hoop fixing point 5, back plate 8.

The utility model utilizes the principle of the communicating device to introduce the ammonium sulfate slurry in the desulfurization circulation tank into the measuring pipe 4 of the liquid level measuring device, and set the scales 3 on both sides of the measuring pipe 4, and the scale corresponding to the liquid level in the measuring pipe 4 can be Read the wiper level of the desulfurization circulation tank. The top of the liquid level measuring device is provided with an anti-air pipe 1 with an opening facing downward, which not only turns the liquid level gauge into a communication device, but also prevents sundries and rainwater from entering the measuring pipe, and can also be connected from the overflow port of the anti-air pipe 1. Temporary tube, backflush the measuring tube 4.

The utility model is a desulfurization circulating tank liquid level measuring device formed according to the principle of the communication device and combined with the structural characteristics of the existing magnetic flap liquid level gauge and glass tube liquid level gauge.
