Title:
SUPPORT STRUCTURE OF POSITIVE POWER GRID IN FILTER
Document Type and Number:
WIPO Patent Application WO/2014/161125
Kind Code:
A1
Abstract:
A support structure of a positive power grid in a filter comprises a support frame (2) used for fixing the positive power grid (1) in the filter, and a support column (3) used for supporting the support frame. A connection column (4) capable of being connected to the support column is disposed on the lower surface of the support frame, and the diameter of the connection column is smaller than that of the support column. According to the support structure of a positive power grid in a filter, because the diameter of the support column is greater than that of the connection column, a step is formed between the support column and the connection column; to-be-treated air blown from the bottom of the support column moves upwards along the outer surface of the support column, dust particles carried in the air are effectively prevented from being attached to the connection column, the connection column is kept clean, the current generated by the positive power grid is prevented from being directly discharged to a lower discharge grid, and sparks are avoided, thereby ensuring the safe operation of a device.
