[0002] Industrial solid waste is waste generated by industrial production, and its quantity is increasing day by day. If industrial waste is passively stored, it will not only occupy a large amount of land and cause waste of manpower and material resources, but also many industrial waste residues contain water-soluble substances, which pollute the soil and water bodies through leaching. Therefore, it is necessary to classify solid waste and carry out appropriate treatment after classification to turn waste into treasure.

[0003] After searching, the existing patent (Announcement No.: CN217595163U) discloses a screening device for industrial solid waste treatment. During use, the rotating shaft is driven by a motor to rotate, and the rotating shaft drives the filter connected thereto to rotate through a belt, and the preliminary screening of solid waste is completed by the rotating motion of the filter; the solid waste after the preliminary screening by the filter is filtered and screened again by pushing the cylinder to drive the movable filter to move horizontally, thereby simply and efficiently classifying and screening the solid waste, and has the advantages of high screening efficiency and good screening effect. However, the inventor found that the prior art has the following problems in the process of realizing the utility model: the above-mentioned screening device for industrial solid waste treatment uses vibration to classify and screen solid waste when in use, but in the actual production process, for industrial solid waste, its surface will adhere to a liquid with high viscosity.
