Testing device and testing method for determining rock salt dissolution rate

The invention discloses a testing device and a testing method for determining a rock salt dissolution rate, and belongs to the technical field of rock salt dissolution measuring instruments. The testing device comprises a main body frame, a clamping mechanism and a weighing machine; the clamping mechanism is used for fixing a salt rock sample on the main body frame; a water inlet pipe of the saltrock sample is connected with a liquid quantitative controller to control the amount of water passing through the salt rock sample; and a water outlet pipe of the salt rock sample extends into a watertank. The testing method comprises the following steps of mounting the testing device, adjusting the amount of water passing through the salt rock sample, adjusting an inclination angle of the salt rock sample through a shaft coupling to change the angle of the water flow passing through the salt rock sample, and analyzing the dynamic water dissolving rule of a salt rock under different flow conditions under consideration
