Description

Technical Field

[0001] The utility model relates to the technical field of cyclone dust collectors, in particular to a cyclone dust collector for sludge drying. Background Art

[0002] In industrial production, sludge needs to be dried. During the drying process, in order to improve the sludge drying efficiency, the sludge is generally stirred. When the sludge is dried to a certain extent and then stirred again, dust is easily generated. To ensure the drying efficiency, while not stopping the stirring, a rotary air dust collector is used to handle the generated dust. In the existing cyclone dust collectors for sludge drying, most of their filtering structures use filter plates for filtering. However, as the dust removal progresses, the filter plates are prone to blockage, thereby affecting the dust removal efficiency. For this reason, a cyclone dust collector for sludge drying is designed, which is convenient for diverting the filtered dust during dust removal, avoiding blocking the filtering channel, ensuring the continuity of dust removal, and at the same time facilitating the rapid cleaning of the filtered dust with high cleaning efficiency.

A chip collecting groove is arranged on the upper conical surface of the cyclone air suction structure and is located below the spherical box. An elevating drive structure for driving the filtering structure to lift is also arranged on the support frame. The specifications of the filter holes on the plurality of filter tennis ball covers decrease from outside to inside.

[0007] Preferably, the cyclone suction structure includes an upper conical cover and a lower conical cover fixedly installed on the upper and lower sides of the support frame.
