Description
Technical field
The utility model is related to blast-furnace equipments, and in particular to a kind of ash exhauster of gravity blast furnace dust catcher.
Background technology
Gravity blast furnace dust catcher is raw coke oven gas dust pelletizing system primary dedusting device, and dust-cleaning principle is unexpected reduction air-flow stream
Speed and change flow direction, the dusts of larger particles is under gravity and inertia force effect, with qi leel from being deposited to deduster cone bottom
Point.Equipment body is designed to the steel construction composition of can-like, and ancillary equipment is mainly by various forms of valves and pipeline, stent etc.
Composition.Blast furnace gas enters gravitational precipitator lower part from blast furnace, and coal gas flows to top always in deduster, and the ash of bulky grain is in weight
Power effect is lower in free falling body state, and the ash for dropping to cone lower part is referred to as primary ash, through three groups of ash exhausters to blender
Discharge.
But during the ash discharge of actual production, original three groups of ash exhausters only have standard-sized sheet or fully closed two states.By
It is in line in original design, it is adjusted without ash uninterrupted, if causing blender work when ash quantity is excessive after any group of long-time standard-sized sheet
Make that electric current is excessively high to lead to failure chaser, therefore, it is difficult to accomplish that this three aspect of mixer motor operating current, water and ash quantity reaches
Matching, therefore it is easy to cause generation dust raising phenomenon.
Invention content
The purpose of this utility model is that designing a kind of ash exhauster of gravity blast furnace dust catcher, blast furnace weight is efficiently solved

It is interior to coordinate with ratchet；One retainer ring of ratchet pin lower part projection, top are arranged a spring, and both ends of the spring is born against in ratchet key seat
Bottom and retainer ring.
Also, the damper includes, damping wheel is coaxially disposed in the shaft other end for stretching out the bearing；Regulation handle,
Its forepart is pivotally connected to the cabinet exterior above the damping wheel by axis pin；Damping tape, one end are connected to described
Regulation handle front end, the other end are connected to the cabinet exterior above the damping wheel side by positioning pin.
Preferably, the corresponding regulation handle, the cabinet exterior also set a rotation scale bar, set several positioning pins thereon
Hole and corresponding positioning pin, with this secured adjusted handle.
When being dropped through impeller, impeller rotates ash under the effect of gravity, and the ash on impeller is passed through rotation side
Formula discharges it.Since the power of impeller is the ash of freely falling body, its rotary speed is depending on the size of ash quantity.Work as ash
Its unit interval speed is then big when measuring big, on the contrary then small.
The size that the utility model adjusts by controlling impeller rotation velocity and controls ash quantity, so as to solve to put ash when, flow
It measures the defects of suddenly big or suddenly small, can be easy to control mixer motor work electricity grey flow control in relatively stable state always
The matching of this three aspect of stream, water and ash quantity, efficiently solves the problems, such as airborne dust during gravity blast furnace dust catcher ash discharge.
The beneficial effects of the utility model：
The utility model realizes the ash discharge flow-rate adjustment control of gravity blast furnace dust catcher, works convenient for mixer motor electric
This three aspect of stream, water and ash quantity can reach best match, efficiently solve the problems, such as airborne dust during gravity blast furnace dust catcher ash discharge,
Also efficiently solve simultaneously mixer motor operating current it is excessively high when failure chaser, reduce the labor intensity of site operation personnel.
The apparatus structure is simple, and it is easy to implement, easy to operate, has good practical function.
