Description

Technical Field

[0001] The utility model relates to the field of dosing devices, in particular to a dosing device suitable for coal preparation plants. Background Technique

[0002] The sedimentation of slime water is an important link in the coal processing process, which involves the separation and recovery of solid particles in the slime water. The slime water generated during coal mining, coal washing, coal transportation, etc., due to containing a large number of fine coal slime particles, has stable suspension and is difficult to achieve solid-liquid separation through natural sedimentation. Therefore, measures such as adding flocculants, adjusting the pH value, and changing the water temperature are required to promote the sedimentation of slime water.

[0003] When adding flocculants, in order to accelerate the sedimentation of slime water, generally, the flocculants are dissolved in water and then added to the slime water. The solution in the liquid storage tank is pumped to the nozzle through a water pump, so as to achieve the addition of flocculants. When the dosing device with this structure is used, since the liquid is added to the slime water and dispersed everywhere through natural flow, there is a problem that the mixing speed of the flocculant liquid and the slime water is slow, which slows down the sedimentation speed to a certain extent.
