Embodiment 1
[0028] Embodiment 1: comprise the following steps:
[0029] (1) Settling: transport the wet-process calcium carbide slurry with a solid content of 8 to 12% to the settling tank, and settling and separating impurities such as ferrosilicon and large-grained carbon particles with a particle size of less than 1mm materials;
[0030] (2) Initial separation by vibrating sieve: the material separated in the above step (1) is subjected to 2 times of vibrating sieving, the mesh numbers of the vibrating sieve are respectively 20 mesh and 100 mesh, which can screen out particles with a particle size greater than 0.85mm respectively. and large particle impurities with a particle size greater than 0.15mm, and then the sieved calcium carbide slurry is directly entered into the ultrasonic vibrating screen for screening by the pipeline;
[0031] (3) Ultrasonic vibrating sieve subdivision: introduce the carbide slag slurry sieved through the above step (2) into a single-layer ultrasonic vibra...
