8. The apparatus for breaking and granulating distillation residue with strong viscosity as claimed in claim 1, wherein the dry powder comprises one or more of sawdust, calcium oxide, and crushed stone powder.
9. A process for crushing and granulating highly viscous rectification residues, which comprises the crushing granulator, the first conveying belt, the second conveying belt, the vibrating screen, the particle collection bin, the distributor, the dry powder collection bin and the bulk material collection bin, and is characterized by comprising the following steps:
s1: respectively loading the dry powder into a vibrating screen and a distributing device, and putting the rectification residues into a crushing granulator;
s2: introducing protective gas into the crushing granulator, starting the crushing granulator and the vibrating screen, and uniformly dropping dry powder from the vibrating screen to be crushed, mixed and uniformly stirred with the rectification residues;
s3: the crushing granulator extrudes the mixture of the rectification residues and the dry powder which are uniformly mixed and stirred into granules, discharges the granules to a first conveyer belt from a discharge port, and discharges gas released in the process by pumping negative pressure in the granulation process;
s4: starting the first conveying belt and the distributing device, so that dry powder in the distributing device is uniformly paved on the surface of the first conveying belt, small particles discharged from a discharge port roll to a particle collecting bin at the lower end of the first conveying belt from the high end of the first conveying belt in an S-shaped route track under the action of gravity on the surface of the first conveying belt, and the residual dry powder and large rectification residues which cannot roll to the particle collecting bin fall to a second conveying belt from the high end of the first conveying belt;
s5: the dry powder falls into a dry powder collecting bin through meshes on a second conveying belt, and the residual large rectification residues fall into a large material collecting bin under the driving of the second conveying belt;
s6: the dry powder recovered in the dry powder collecting bin can be placed in a vibrating screen and a distributing device for repeated use, and the large rectification residues in the large material collecting bin are returned to the crushing granulator again for circular crushing.
10. The process for crushing and granulating rectification residues with strong viscosity as claimed in claim 9, wherein a crushing cutter set for stirring and crushing rectification residues is arranged in the crushing granulator, the crushing cutter set is arranged above the discharge port, an extrusion granulation plate is arranged on the discharge port, a plurality of granulation ports are formed in the extrusion granulation plate, and a rotary scraper is arranged below the extrusion granulation plate; in step S3, the granulation process specifically includes: the rectification residues are crushed and stirred by the crushing cutter set and are uniformly mixed with the dry powder, then the mixture is extruded by the crushing cutter set and the extrusion granulating plate, so that the mixture is extruded from a granulating opening of the extrusion granulating plate, and the extruded mixture is cut into small cylindrical particles by a rotary scraper below the extrusion granulating plate.
