But in device air feed secondary air fan, the dust sucting pipeline being connected with kiln hood outlet aniseed storage room connect with secondary air fan, makes powder
Dirt is blasted in shaft cooler by dust sucting pipeline with cold air.
Bulk materials discharger includes the grid section being filtered to the discharging of limekiln kiln hood, is arranged on the kiln hood of limekiln
Aniseed clear out door and be connected to aniseed and clear out the transmission channel of door and kiln hood outlet aniseed storage room.
Dust sucting pipeline further includes a plurality of dust suction lateral, and a plurality of dust suction lateral suction inlet corresponds to multiple except dirt pits is set
It sets, a plurality of air duct pipe is simultaneously connected on the secondary air fan of shaft cooler.
Secondary air fan is the air blower with variable-frequency motor.
The impeller of secondary air fan is abrasion proof impeller.
The utility model beneficial effect is: (1) secondary air fan processing air quantity is big, and fans entrance ventilation shaft is directly accessed kiln
Head outlet aniseed room carries out space dust removal, no longer adds other dedusting corollary equipments, not only fugitive dust during the row's of can be reduced aniseed
Caused by environmental pollution reduce equipment investment cost simultaneously, reduce the power consumption of deduster draught fan matching later period operation.And it removes
Dirt and discharge link, and reduce processing step and technology controlling and process time.Dust collection is directly comprehensive with subsequent technique, it reduces to powder
The cleaning of dirt can improve yield to the recycling of lime dust.
(2) since fugitive dust point each in workshop all imports secondary air fan by air supply line, reduce either inside dust and cause
Environmental pollution.
