Method and structure for preventing mud from blocking radar level gauge detection probe

Abstract

The invention discloses a method and structure for preventing mud from blocking a radar level gauge detection probe. According to the method, a mounting hole which is arranged on the top of a red mud storage tank is enlarged to be more than three times of the diameter of the radar level gauge detection probe, a guide pipe which is 1.5 times of the length of the radar level gauge detection probe is welded to the mounting hole, the top of the guide pipe is connected with a radar level gauge through a flange, the radar level gauge detection probe is located in the guide pipe, and the mud is prevented from blocking the radar level gauge detection probe. By means of the method and structure, interference on liquid level measurement caused by the mud splashed from the red mud storage tank with a stirring device can be avoided effectively, and the labor intensity of overhaul and maintenance personnel and dangerous situations are greatly reduced. Through practices, the accuracy of the liquid level measurement is greatly improved, the safe production requirement is met, and the maintenance is convenient. The method and structure have the advantages that the structure is reasonable, the installation is convenient, the measurement is accurate, and the manufacture cost is low.

Description

technical field [0001] The invention relates to a method and structure for preventing mud from clogging a detection probe of a radar level gauge, and belongs to the technical field of level measurement of red mud storage tanks in alumina production by Bayer process. Background technique [0002] In the Bayer process alumina production enterprise, many sections involve the measurement of the level of the red mud storage tank with a stirring device, which is measured by a radar level gauge installed on the top of the red mud storage tank. The detection probe at the bottom of the existing radar level gauge is lower than the top plate of the red mud storage tank. When the stirring device in the red mud storage tank is stirring, the mud in the storage tank will be splashed. The splashed mud will often block the detection probe at the bottom of the radar level gauge, affecting the transmission of radar waves, thereby affecting the accuracy of material level measurement, and in ser...

AI Technical Summary

Problems solved by technology

The splashed mud will often block the detection probe at the bottom of the radar level gauge, affecting the transmission of radar waves, thereby affecting the accuracy of material level measurement, and in severe cases, it cannot be measured at all

Therefore, it is necessary to stop frequently to clean the mud near the detection probe at the bottom of the radar level gauge to meet the measurement requirements, which increases the maintenance cost of the equipment and affects the production efficiency.
