Manufacturing equipment and preparation method of carbide slag slurry and carbide slag slurry

The invention relates to manufacturing equipment and a preparation method of carbide slag slurry and the carbide slag slurry. The manufacturing equipment comprises a spiral feeder, a slurry preparation tank, a sand-water separator, a first-stage rotational flow station, a second-stage rotational flow station and a fine slurry storage tank which are connected in sequence, wherein dry slag enters the slurry preparation tank through the spiral feeder, coarse slag slurry stirred and mixed by the slurry preparation tank enters the sand-water separator, after large-particle impurities are removed by the sand-water separator, the coarse slag slurry is conveyed to the first-stage cyclone station through a slag slurry pump, and slurry treated by the first-stage cyclone station is conveyed to the second-stage cyclone station through a pump to be concentrated; and the fine slurry which is treated by the second-stage cyclone station and meets the concentration requirement automatically flows into the fine slurry storage
