Description
Technical field
This utility model relates to the correlative technology field of a kind of cleaning shaft, particularly relates to a kind of cleaning shaft velocity of medium
Detection device.
Background technology
Cleaning shaft is as the term suggests being used to transmit flue dust, flue dust, cabo and other tobacco waste and (being hereinafter referred to as situated between
Matter) transmission channel, pipe diameter typically takes between 110～150mm, and one end of cleaning shaft connects the dedusting within cigarette machine
Catcher, one end connects sack cleaner, and pocket type dehydrater connects dedusting fan.Cleaning shaft, dust collector and pocket type remove
Form an airtight vacuum passage between dirt device three, when cigarette machine dedusting to be discharged, have a signal and transmit to removing
Dirt blower fan, activates dedusting fan and runs, and the powerful negative-pressure air-suction of generation makes the dust collector in cigarette machine by medium along removing
