Abstract

A two-stage cyclone separation dust collector comprises an outer dust barrel provided with an outer air inlet. An inner dust barrel is further disposed in the outer dust barrel. A mesh cover drum corresponding to the outer air inlet is disposed above the inner dust barrel. The inner dust barrel, the mesh cover drum and the outer dust barrel enclose a primary cyclone cavity. A rotary conical drum is nested into the mesh cover drum. The upper end face of the rotary conical drum is rested at the upper end of the mesh cover drum. The upper end of the rotary conical drum is further provided with a circle of inner tangential air inlet which is located between the rotary conical drum and the mesh cover drum. An air outlet cover surrounding the rotary conical drum covers the rotary conical drum. A pendent cylindrical cyclone drum extending into the rotary conical drum is disposed at the center of the air outlet cover. A mesh cover plate filled with filter cotton covers the air outlet cover. The two-stage cyclone separation dust collector has the advantages that two-stage cyclone separation is used, dust separation is thorough, and coarse ash and fine ash separation is achieved; the primary cyclone system uses the mesh cover drum, the secondary cyclone system uses the signal conical structure, so that the two-stage cyclone separation dust collector is simple in structure, low in cost and good in effect.
