Description

Technical Field

[0001] The utility model relates to the technical field of fly ash, in particular to a recovery and classification device for fly ash floating beads. Background Art

[0002] Floating beads are hollow balls of fly ash that can float on the water. They are grayish white in color, thin in wall and hollow in center. They are very light in weight, with a bulk density of 720kg / m3 (heavy) and 418.8kg / m3 (light). The particle size is about 0.1mm, the surface is closed and smooth, the thermal conductivity is low, and the refractoriness is ≥1610℃. They are excellent thermal insulation and refractory materials, and are widely used in the production of lightweight castables and oil drilling.

[0003] However, in the prior art, after a multi-stage filtering and recovery device for floating beads has been working for a long time, debris is easily accumulated on the surface of the filtering device, resulting in reduced filtering efficiency or even blockage, which affects the recovery of the floating beads. For this reason, we propose a recovery and grading device for fly ash floating beads. Utility Model Content
