4, difference gauge monitoring filtering layer resistance drop is set.
The operation of separator: powder is sent into fluid bed 1 through batcher 2 and feeder 3, and air enters fluid bed 1 from air distribution plate 4 under air-introduced machine 19 attracts, and with the powder fluidisation, wherein, fine powder is raised folding from fluosolids, raises the folding maximum particle size and regulates by controlling valve 18.Granule less than net formula baffle plate 13 apertures in the fluosolids overflows in mesh, with air-flow and raise the folding fine powder through linked hole 12, under the effect of flow apron 14, air-flow changed course, diffusion, reduction of speed, powder is thrown to the bottom of catching powder storehouse 10 under inertia force and gravity effect, subparticle then rises with air-flow, captures through filter 15 and stays in catching powder storehouse 10, purify air through converging air chamber 16, exhaust outlet 17, enter atmosphere by air-introduced machine 19.Fine powder characteristic in the design consideration powder of filter 15 can be a single chamber, and the fine powder layer comes off under the gravity effect after running up to certain thickness automatically; Also can be two chambers, adopt the forced action type bed of material that comes off.Fluosolids does not overflow and the thick component of not raising folding is called the bed material, though especially big particle can not be fluidized in the bed material, can move about to lowest part rapidly along the air distribution plate slope under the fluidizing agent effect yet.Bed material from discharge duct 4 through discharging machine 5 continuous controllable send into sifter 7, sieve out each required grade product.A small amount of granule of carrying under one's arms in the bed material sifts out through the sifter bottom, is sent back to by returning charge machine 9 and catches powder storehouse 10, concentrates discharging, the returning charge machine 9 that also can reverse, directly discharging.Since in the bed material fine powder content seldom, so the saturating sieve ability of bed material improves greatly, dust is also eliminated substantially when screening simultaneously.
With the miniature powder separation device of 6t/h is example, and the smalls that the Fujian anthracite of full moisture content below 10% is carried out granularity d＜25mm separates, and obtains promising result.
For high moisture content powder, the utility model then can be realized drying and separate synchronization job by installing the calandria heat exchanger at fluid bed additional or setting up hot-blast stove.
