In the industry of former Smelting magnesium, it has also become current most important former Smelting magnesium technology.In magnesium-smelting silicothermic process production process, process knot is reduced
Shu Hou, it is both needed to discharge reducing slag from reductive jar, is then fed again.During deslagging, the reducing slag flying dust of high temperature floats
Tank mouth periphery or even whole workshop are being reduced, is directly endangering the health of operator.Compared with conventional production of magnesium by pidgeonprocess technology,
The reductive jar of vertical retort magnesium smelting technology is erected in reduction furnace, realizes auto feed and deslagging using raw material self gravitation, significantly
Shorten the operating time, reduce labor intensity and recruitment.But the phenomenon that reducing slag flying dust is flown upward everywhere in tapping process is still deposited
In the operating environment very severe of worker.
The content of the invention
The technical problems to be solved in the utility model is：During for existing perpendicular tank Smelting magnesium technology deslagging tank mouth periphery or even
The problem that whole workshop reducing slag flying dust is flown upward everywhere, operation bad environments and pollution environment are serious, the utility model carry
For a kind of Smelting magnesium negative pressure slag-draining device.When carrying out deslagging using the utility model device, set by slag storehouse porch negative
Dust collecting system is pressed, reducing slag and flying dust are separated, negative pressure deslagging is realized, avoids the reducing slag flying dust of high temperature from being flown away to workshop, from
And improve operation environment.
In order to solve the above problems, the utility model adopts the technical scheme that：
The utility model provides a kind of Smelting magnesium negative pressure slag-draining device, including erects tank slag-drip opening, leads slag cylinder and slag storehouse, its
In：Also include exhaust duct, air extractor and dust filtering device, the perpendicular tank slag-drip opening bottom is provided with and leads slag cylinder, leads slag cylinder
Bottom is provided with slag storehouse, and slag storehouse porch is provided with exhaust duct, air extractor and dust filtering device.
According to above-mentioned Smelting magnesium negative pressure slag-draining device, slag storehouse porch is connected with exhaust duct, exhaust duct and pumping
Device is connected, and air extractor is connected with dust filtering device.
According to above-mentioned Smelting magnesium negative pressure slag-draining device, slag storehouse porch is connected with exhaust duct, exhaust duct and dust
Filter is connected, and dust filtering device is connected with air extractor.
According to above-mentioned Smelting magnesium negative pressure slag-draining device, the air extractor is blower fan, vavuum pump or jet pump.
The operating process of deslagging is carried out using the utility model Smelting magnesium negative pressure slag-draining device：Produced after Smelting magnesium reduction reaction
Raw reducing slag and its flying dust is discharged from perpendicular tank slag-drip opening, and slag cylinder is led into reducing slag；Reducing slag and its flying dust are by leading slag cylinder
Into slag storehouse, when reducing slag and its flying dust pass through slag storehouse porch, the discharge tube that flying dust is provided with through slag storehouse porch is by being evacuated
The negative-pressure gas that device is passed through introduces exhaust duct（The flow velocity of negative-pressure gas is 5~25m/s）；Flying dust is passed through by air extractor
After negative-pressure gas introduces exhaust duct, discharged after dust filtering device is handled；After reducing slag separates with the flying dust carried, enter
Collect in slag storehouse.
The utility model Smelting magnesium negative pressure slag-draining device, in tapping process, perpendicular tank slag-drip opening, lead between slag cylinder and slag storehouse
Interface and other position leaked-in airs and reducing slag flying dust, aspirated through air extractor, by the row for being located at slag storehouse porch
Wind pipeline is discharged, and is filtered through dust filtering device, is realized the collection of reducing slag flying dust.
Positive beneficial effect of the present utility model：
, will be also by the negative pressure dust collecting system of slag storehouse porch setting when the 1st, carrying out deslagging using the utility model device
Former slag and flying dust separation, realizes negative pressure deslagging, avoids the reducing slag flying dust of high temperature from being flown away to workshop, so as to improve operation ring
Border.
2nd, the utility model Smelting magnesium negative pressure slag-draining device passes through preliminary identification, significant effect：High temperature when avoiding deslagging
Reducing slag flying dust flies away to workshop, improves operation environment.
