Description

Technical Field

[0002] Coal flotation is a commonly used coal sorting technology. Through the action of coal flotation solution (flotation agent), the coal particles and other impurity particles are differentiated in affinity, thereby achieving effective separation of coal and impurities.

Through a scientific and reasonable preparation process, the efficiency of coal flotation can be improved, production costs can be reduced, and it is also beneficial to environmental protection and safe production.

[0003] At present, when preparing the flotation agent, a certain amount of water is usually injected into the preparation tank first, and then the corresponding solution raw materials are added to the preparation tank in proportion; the specific method of adding the solution raw materials is generally: the solution raw materials are introduced into the preparation tank through a metering pump to facilitate the control of the amount of raw materials added; a stirring structure is generally set in the preparation tank to accelerate the mixing speed of the solution.

[0047] When the utility model is in use:

[0048] The slot cover 1 is installed on the preparation tank; in the initial state, the premixing barrel 11 is located above the feed slot hole 24, and the sealing cover 15 is located at the bottom end of the limit rod 14 in the premixing barrel 11; when preparing the solution, the corresponding external solution raw material supply device is started to guide the material into the premixing barrel 11 through the flexible conduit 13 and the feed pipe 12, and the motor 3 is started at the same time.
