Description

Technical Field

[0001] The utility model relates to the field of physical measuring devices, in particular to a tailings underwater repose angle measuring device. Background Art

[0002] Solid particles in still water can form a certain inclined surface without collapsing due to the friction between the particles. The angle φ between this inclined surface and the horizontal plane is called the underwater angle of repose of the particle, also known as the underwater angle of repose. Common measurement methods include the plate drawing method and the disc method.

[0003] The plate-pulling method is to make a transparent organic glass water tank, seal both ends, set a baffle at 1 / 3 of the water tank and fill it with solid particles. After filling, slowly pull out the baffle, and the particles will slide down under the action of underwater gravity to form a stable slope. The slope is the underwater repose angle of the particles. However, this method has a certain force on the solid particles due to the artificial operation of the baffle, so there is a possibility of particle adhesion, especially for fine particles.

[0004] The disc method is to place a disc with a diameter of 20 cm in a glass cylinder filled with clean water, and send solid particles into the center of the disc through a funnel fixed on the water surface, pile the particles into a cone, measure the cone height with a probe, and calculate the slope of the cone, which is the underwater repose angle of the particles. However, this method is suitable for large solid particles such as sand and gravel, and is not suitable for underwater repose angle measurement of fine-grained tailings that are easily soluble and dispersed.
