Abstract
A kind of adjustable blast furnace gravitational dust collection ash exhauster of flow, including, blanking body, it is a babinet, which forms blanking channel, and babinet one side opening simultaneously accordingly sets a maintenance door to be opened/closed；Babinet upper and lower end sets a connecting flange respectively；Two pieces of fender plates, its side are movably connected on two side top in the blanking body box body by a shaft, and, the front end of two pieces of fender plates overlaps up and down, and formation can be opened and closed blanking channel structure；Two adjusting aperture screw rods, are correspondingly arranged in the blanking body babinet both sides respectively, its end is stretched into babinet, and against two pieces of fender plate lower faces, adjust two pieces of fender plate flip angles with this, and then adjust blanking channel aperture.Ash discharge flow is controlled when the utility model is used for blast furnace gravitational dust collection ash discharge operation, prevent because in the unit interval ash quantity it is excessive caused by dust pollution and stirring cage motor device overload fault.
Description
Technical field
Blast-furnace equipment is the utility model is related to, more particularly to a kind of adjustable blast furnace gravitational dust collection ash exhauster of flow.
Background technology
Gravity blast furnace dust catcher is first group of dust-extraction unit of blast furnace crude gas system, by shell is simplified, core pipe, stent,
The steel construction pieces such as each layer platform and ash exhauster form.Deduster core pipe top is connected with blast furnace down-comer, raw in blast furnace process
Into the very high coal gas of dustiness, enter deduster core pipe through down-comer, change airflow direction in cylinder, pass back into half clean coal
Gas is responsible for, into cleaning coal gas device.The reverse reflux of coal gas makes dust of the particle diameter more than 150 μm fall under the effect of gravity,
Separated from air-flow.The dust for dropping to simplified hypocone is referred to as once ash, is arranged through three groups of ash exhausters to mixer
Go out, then blast furnace region is carried out by truck and is recycled.
The ash quantity of daily gravitational dust collection is between 100 to 200 tons by taking certain blast furnace as an example, and whole discharge process is when 3 to 4 is small
Left and right.It is once grey to avoid being provided with the mixing of adjustable dispensing device for water in airborne dust technique, then give off gravity after being mixed by mixer
Dedusting is unloaded into truck, and strictly controls mixer operating current between 50-70A, but due to the difference of person works' experience
Different and the generation that works long hours fatigue, it is difficult to be affectedly bashful always optimal mixer operating current, water and ash quantity this three
The matching of key element, causes dust raising phenomenon occurs once in a while.
There was only the fully closed two states of standard-sized sheet, any group of long-time standard-sized sheet by the original three groups of ash exhausters of field observation
Afterwards ash quantity it is excessive carry out fetching water again cause the excessive failure chaser of mixer operating current, conventional counter-measure is to three groups of ash discharges
Device is opened and closed in turn, constantly switches over the normal work for ensureing mixer, ash discharge amount is suddenly big or suddenly small in this handoff procedure
So that water is also required to constantly adjust, the working strength of field worker is greatly improved, it is careless slightly to cause
Airborne dust, this does not meet the main trend of industry 4.0, or solves site problems by manpower.If lift the work of mixer
Then cost is excessively high for ability, and reduce the caliber of gravitational dust collection ash exhauster it will cause ash exhauster block it is serious after
Fruit.
Utility model content
The purpose of this utility model is that a kind of adjustable blast furnace gravitational dust collection ash exhauster of flow is designed, for blast furnace weight
During power dedusting ash discharge operation control ash discharge flow, prevent because in the unit interval ash quantity it is excessive caused by dust pollution and stirring cage motor
Equipment overload fault.
To reach above-mentioned purpose, the technical solution of the utility model is：
A kind of adjustable blast furnace gravitational dust collection ash exhauster of flow, including, blanking body, it is a babinet, on the babinet,
Under shed forms blanking channel, and babinet one side opening simultaneously accordingly sets a maintenance door to be opened/closed；Babinet upper and lower end is set respectively
One connecting flange；Two pieces of fender plates, its side are movably connected on opposite two in the blanking body box body by a shaft
Side wall upper part, and, the front end of two pieces of fender plates overlaps up and down, and formation can be opened and closed blanking channel structure；Two adjusting apertures
With screw rod, the blanking body babinet both sides of corresponding two pieces of fender plates are respectively arranged at, its end is stretched into babinet, and is supported
By two pieces of fender plate lower faces, two pieces of fender plate flip angles are adjusted with this, and then adjust blanking channel aperture.
Preferably, the maintenance door is connected to the blanking body body side opening with articulated connecting mode.
Preferably, one U-shaped fixed block of projection on the outside of the maintenance door, corresponding, blanking body body side opening is set
Fixed link, the fixed link are sticked in the U-shaped fixed block.
The beneficial effects of the utility model：
1st, the utility model is designed by fender plate, can be controlled into ash quantity size in mixer, will not be because of ash
Amount is excessive to cause mixer overload fault to shut down influence operation.
2nd, fender plate reduce dust removing system by caliber, and can be opened and closed cleaning at any time stifled for the setting of maintenance door
Plug.
3rd, the utility model solves the problems, such as blast furnace gravitational dust collection ash discharge airborne dust, prevents mixer overload fault from shutting down,
And significantly mitigate site operation personnel's labor intensity.
