The invention relates to an atomized fall type
coal paste
preprocessor. A sliding plate is fixedly connected to the two sides of a lower tank body of a fall tank, a vertical shaft of a
fogging disc is connected with an output shaft of an
electric motor, an upper tank body of the fall tank is provided with a central feeding
pipe and an overflow launder; wherein the overflow launder is internally provided with baffle plates; a
slide plate comprises an upper
slide plate and a lower
slide plate, a ridged bar is fixedly connected on the slide plate; the vertical shaft of the
fogging disc is externally sheathed with a sleeve, the lower part of the sleeve is provided with a chemical feed
pipe which is communicated with a chemical feed hopper, the lower end of the chemical feed
pipe is placed above the front surface of the
fogging disk; a coupler is a flexible coupler. In the invention, the front surface of the fogging disk is the working surface; floating agent automatically flows to the working surface under the action of static pressure, thus avoiding blockage caused by impurities; with the fall tank, repeated fall of
coal paste is realized, so that
sufficient time is provided to contact and fully mix with the floating agent having gong through atomization and dispersion, thus facilitating formation of enough and stable
oil film on the surface of the fogging disk; the slide plate with ridged bars is set with different contact pretreatment time for medium-thickness and fine particles of the
coal paste, thus creating fine technological conditions for coal paste pretreatment.
