Description
Technical field
The invention belongs to sealed valve and discharge apparatus technical field, relate in particular to a kind of sealed valve discharging method, also relate to the discharge device that uses the method, be applicable to unloading valve and condenser discharge mechanism etc.
Background technology
Sealed valve discharge is mainly used on the discharge mechanism of unloading valve and condenser.Unloading valve is the indispensable ash-discharging device of dry collector and material-transporting system, and dust exhaustor concentrates on the dust of collecting in collector for duster ash bucket, then is discharged by unloading valve.Unloading valve is applicable to granular material and granulated material, in industrial sector widespread uses such as environmental protection, metallurgy, chemical industry, grain, food.In order to guarantee the normal operation of dust exhaustor, unloading valve must be reliable, unload the smooth and sealing of ash.Condenser is mainly used in needing in textile industry the occasion of conveying or transfer raw material, its principle of work is: raw cotton or chemical fibre are under the stream pressure effect of blower fan, by cotton delivery pipe, constantly condense upon mesh dust cage surface, short flannel in cotton flow and dirt bits are by dust cage mesh Fan pipeline, enter dust-filtering system, the raw cotton or the chemical fibre that condense upon dust cage surface strip next board of lower feeding in stripping hired roughneck's revolution.
At present, unloading valve mainly has following three kinds of forms: the first is star-shaped dust-discharging valve, it is mainly by motor, planetary gear speed reducer (or pin synthetic fibre cycloid speed reducer) with turn imperial formula discharger and form, rely on the Action of Gravity Field of material and the positive action of feeder operating mechanism, material in storehouse is drawn off also and feeds in next device continuous uniform and go, but, more and stuck phenomenon easily occurs while having large granular materials at material, and existence gas leakage, because cinder-discharging port can produce certain negative pressure, also be easy to produce reentrainment of dust, the stripping hired roughneck of condenser is the same with the principle of work of star-shaped dust-discharging valve, the second is plate turnover ash discharge valve, it is to utilize material in feed bin or ash bucket to the pressure of valve plate, valve plate to be opened, material unload a certain amount of after, pressure on valve plate reduces and realizes and automatically closing, in discharge process, due to the material drawing off is not had to thrust, large granular materials is easily put up a bridge, and there is stuck phenomenon, also there will be reentrainment of dust simultaneously, the third is screw rod unloading valve, and screw rod unloading valve equally also has gas leakage and stuck shortcoming.
For textile industry, the collected dust of dust exhaustor mainly contains dust and fiber suede, and fiber suede wherein causes major cause stuck and that put up a bridge just.Therefore, how to guarantee that it is current industry problem demanding prompt solution that unloading valve unloads grey smoothness.
