Abstract
Provided is a dust discharge valve for a blast furnace gravity dust collector. The technical scheme is that the dust discharge valve for the blast furnace gravity dust collector comprises a ball vale arranged at the upper portion and a plate valve connected with the ball valve, and an outlet of a valve body of the ball valve is connected with an inlet of the valve body of the plate valve. The ball valve serves as a first valve to have the sealing function, and a second valve uses openness of the plate valve to adjust dust amount and have the sealing function. The dust discharge valve for the blast furnace gravity dust collector has the advantages of being good in sealing performance, controllable in dust discharge amount and long in service life.
Description
Technical field
The utility model is a kind of gravity blast furnace dust catcher unloading valve.
Background technology
Blast furnace production is a smelting process continuously, in smelting process, produces a large amount of raw gas, and the dust content in the raw gas approximately is 30g/m
3, must just can carry out second stage employ through purifying treatment, and gravitational precipitator is a visual plant of handling the blast furnace raw gas; After the blast furnace raw gas gets into gravitational precipitator since the space enlargement flow velocity reduce; Inner contained dust granules falls to piling up under the self gravitation effect, and the dust of these accumulations must regularly be discharged through unloading valve, otherwise; The gravitational precipitator residual volume is too small when dust accretions arrives to a certain degree, will influence dust removing effects.
The gravity blast furnace dust catcher unloading valve adopts a kind of single conical surface, awl seat sealed structure at present, and its open degree is less, and flow out in the less gap that dust is opened through valve seat, valve gap when putting ash; Two conical surfaces are caused wash away, moist dust is prone to be bonded in valve gap, the contact surface of valve seat in discharge, when valve closes; Because valve gap, the contact surface of valve seat have the dust dung to exist; Very easily cause the valve closes imprecision, a large amount of coal gas is excessive, above-mentioned situation occurs; The lighter causes blast furnace staying to influence the ordinary production process, weight person's serious threat post worker's life security.
Summary of the invention
The utility model provides a kind of good airproof performance to the deficiency of prior art, Dust Capacity discharging controlled amount, the technical scheme of the gravity blast furnace dust catcher unloading valve of long service life.
The utility model is realized through following technical measures: a kind of gravity blast furnace dust catcher unloading valve comprises being positioned at top ball valve and the plate valve that is connected with ball valve that the ball valve body outlet is connected with plate valve valve body inlet.Wherein the first road valve adopts ball valve, mainly is to play sealing function, and the second road valve is through the aperture of valve plate and then plays the effect of regulating Dust Capacity size and sealing.
The concrete characteristics of the utility model also have; Above-mentioned ball valve body comprise the ball valve upper valve body that has upper flange plate, with ball valve that the ball valve upper valve body cooperates under valve body; The ball-type spool is installed in the valve body under ball valve upper valve body and the ball valve; Between said ball valve upper valve body inside and the ball-type spool gasket is installed, the ball-type spool is connected with the ball valve drive unit.
Above-mentioned ball valve drive unit comprises the turning axle that is fixedly connected with the ball-type spool; Said turning axle is fixedly connected with an end of cranking arm; The piston rod overhanging end of the said the other end of cranking arm and oil cylinder is hinged; Said cylinder block is hinged on the cylinder bracket, and said cylinder bracket is fixedly mounted under the ball valve on the valve body.
Above-mentioned plate valve comprises plate valve valve body and the valve plate that cooperates with the plate valve valve body, and said valve plate is connected with the plate valve drive unit.
Above-mentioned plate valve drive unit comprises that the universal joint that is connected with valve plate connects; Universal joint is fixedly connected with pivoted arm one end; One end of the other end of pivoted arm and turning axle is hinged, the other end of said turning axle with crank arm hingedly, the overhanging end of the said the other end of cranking arm and oil cylinder piston bar is hinged; Said cylinder block is hinged on the cylinder bracket, and said cylinder bracket is fixed on the plate valve valve body.
Valve body is connected through bolted under above-mentioned ball valve upper valve body and the ball valve.
Above-mentioned plate valve valve body is provided with inspection manhole.
The beneficial effect of the utility model is: good airproof performance, Dust Capacity size can be regulated; The utility model is simple in structure, convenient to operation, with low cost, save time, safe; Life cycle is long, and can change according to the wear pattern of valve plate.Especially after long-time the use, first road occurs when poorly sealed, can carry out secondary seal, solved thoroughly that life cycle is short, sealing effectiveness is bad and the big or small uncontrollable difficult problem of dust discharge amount through the valve plate that the Dust Capacity size is regulated in second road.This unloading valve is that to adopt hydraulic pressure be propulsion source simultaneously, and the Kai Heguan of the extension and contraction control valve through oil cylinder has realized remote manipulation, and the opening angle of valve is arbitrarily adjustable and control automatically.
