Slag tap after refining magnesium finishes, the slag tapping method of this vertical retort magnesium smelting is: open loam cake, take out a jar interior annex; Open lower cover, the lifting pipe core of hanging oneself is opened slag notch, and slag charge relies on the gravity free-falling to slag tap.There is following shortcoming in this slag tapping method:
Reduction jar gas stirring is violent when 1, slagging tap, and dust is gone out from a reduction jar port, and the production scene airborne dust is serious, and workman's operating environment is abominable;
2, slag charge is attached on the reduction jar inwall easily, and the adherent slag charge is not only cleared up difficulty, and can dwindle the useful volume of reduction jar, reduces one-pot material amount; When the situation that paulin appears taking in the raw material sintering, slag charge can not smooth and easyly be got rid of;
3, slag charge relies on gravity fall, can not control the velocity of discharge of slag charge.
Summary of the invention
Technical problem to be solved by this invention just provide a kind of on-the-spot airborne dust few, can clear up slag charge that is attached on tank skin and the vertical retort magnesium smelting slag tapping method that can control the slag charge velocity of discharge automatically, and a kind of vertical retort magnesium smelting device of implementing this method is provided.
Solve the problems of the technologies described above, vertical retort magnesium smelting slag tapping method of the present invention adopts following steps:
Step 1 is opened loam cake, takes out reduction jar interior annex, closes loam cake then;
Step 2 is laid deslagging device below slag notch, open lower cover, regulates the rotation push rod of deslagging device, and the cock that the rotation push rod is up moved with the shutoff slag notch is connected, and relies on the top of going up of rotation push rod, and slag notch is opened, and slag charge begins to discharge;
Step 4, slag tap accomplish after, oppositely regulate deslagging device, the rotation push rod descends, cock and pipe core are return and are fallen to resetting with rotating push rod, rotate push rod at last and separate with cock, remove deslagging device.
For implementing aforesaid method, vertical retort magnesium smelting device of the present invention includes reduction jar and pipe core, and pipe core is movably arranged in the reduction jar; The reduction pot bottom is a slag notch, on the said pipe core blade is installed, and the pipe core bottom is fixedly connected with cock; Cock is used to open and close slag notch, below slag notch, lays movably deslagging device, and the rotation push rod of this deslagging device pushes up through on the slag notch; Be connected with cock and slag tap and to clear up slag charge realizing; Slag tap after the completion, the rotation push rod falls, and separates voluntarily with cock.
Compare with the slag tapping method of existing vertical retort magnesium smelting, advantage of the present invention has:
1, effectively reduced the dust of production scene, when slagging tap, loam cake can be closed, and has avoided dust to go out from a reduction jar port, and the blade of installing on the pipe core has barrier effect to dust, has improved labor condition;
2, can clear up slag charge automatically, to thoroughly slagging tap in the reduction jar, under the rotation of pipe core blade is stirred, can effectively solve the problem of taking paulin such as slag charge, when the rotation of pipe core blade was slagged tap, its outer rim can be wiped adherent slag charge on jar inwall off;
3, may command tapping process through regulating pipe core and blade rotational speed thereof, can be controlled the velocity of discharge of slag charge, realizes the target of controlledization deslagging.
