The invention relates to the field of liquid solid erosion devices, and concretely relates to a built-in stirring device. The device is provided with a seated submersible pump, a first wing-shaped diversion tube, a T-shaped outlet diverter, a slurry tank and a second wing-shaped diversion tube, the T-shaped outlet diverter is arranged at the outlet of the seated submersible pump to make a fluid bedivided into two streams by the T-shaped outlet diverter and enter diversion tubes, and outlets at two sides of the T-shaped outlet diverter are respectively connected with a first wing-shaped diversion tube one and the second wing-shaped diversion tube. After the assembling the device is finished, the device is arranged at the middle of the bottom of the slurry tank, and a cable plug is led to the outside of the slurry tank. After solid particles and a liquid are added according to a certain ratio, the submersible pump is started, and a medium is sucked in from the bottom of the submersiblepump, and is sprayed from the two wing-shaped diversion tubes to form a strong eddy current at the bottom of the slurry tank, so the solid phase and the liquid phase are effectively mixed. The devicesolves the problem of insufficient suspension of heavy and large solid phase particles in existing pipe erosion corrosion experimental devices, and improves the reliability of the erosion test of a heavy and large solid phase particle system.
Description
technical field [0001] The invention relates to the field of liquid-solid erosion devices, in particular to a built-in stirring device for promoting effective suspension of solid phase particles in liquid-solid erosion tests. Background technique [0002] In the existing technology, liquid-solid erosion mostly uses rotary, pipe-flow, and jet-type experimental devices. The pipe-flow device is based on the liquid flow / pipeline static structure, which can better simulate the axial direction of the fluid along the inner wall of the pipe. However, the mixing system adopted by the traditional pipe flow type often has the problem of insufficient particle suspension for the case of large solid particle density or particle size. The ratio is quite different. Contents of the invention [0003] The purpose of the present invention is to provide a built-in stirring device that promotes the effective suspension of solid phase particles in the liquid-solid erosion test, so as to solve ...
