Description
Technical Field
The utility model belongs to the field of crude magnesium refining ventilation devices, in particular to a crude magnesium refining crucible ventilation device.
Background
At present, a ventilation system adopted in a crude magnesium refining process is simple in structure, a left cover plate and a right cover plate need to be opened first during operation, crude magnesium is added to start smelting, the ventilation has certain efficiency when the cover plates are closed, but the left cover plate and the right cover plate need to be opened in subsequent addition of a fusing agent and a collapsing agent, the ventilation efficiency is deteriorated, the industrial sanitary condition of the process is poor, and the ventilation air suction hood for the root cause can not meet the technological requirements.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide a ventilation device for a crude magnesium refining crucible.
The purpose of the utility model is realized like this: a kind of crude magnesium refining crucible ventilating device, including the furnace body, characterized by that: the furnace body inboard be provided with the crucible, the furnace body top is provided with ring slit side suction hood, ring slit side suction hood top is provided with fire-resistant notes material that burns, one side that ring slit side suction hood is close to the crucible is provided with ring slit inlet scoop, the opposite side of ring slit side suction hood is provided with special-shaped collection pipe, the inside guide plate that is provided with of ring slit side suction hood, the guide plate includes forward guide plate and reverse guide plate.
The annular slit side air draft cover main body is a revolving body with a rectangular cross section, and annular band-shaped refractory castable is tied above the revolving body and is flush with the workbench in height.
The ring slit side suction hood is provided with a special-shaped collecting pipe communicated with an external waste gas treatment system.
The suction hood at the side of the annular slit is provided with an annular slit suction opening on the cylindrical surface opposite to the crucible.
The ring slit side air draft cover is characterized in that a forward guide plate and a reverse guide plate are arranged in the revolving body, and the guide plates are arc-shaped and symmetrical to the wind speed direction at the convergence part.
The side suction type is adopted by the ring slit side suction hood, the wind speed of the hood opening is 7-10 m/s, and the control wind speed of the central point of the crucible is 0.5-1 m/s.
The utility model discloses a design of ring slit side suction hood, uncovered operation has been realized, the cover mouth openly faces to the cover that induced drafts that contains gaseous air current, make the kinetic energy that the cover make full use of induced drafts contains gaseous air current, with the improvement ventilation effect, arranged the guide plate in the cover and along compiling a wind speed direction symmetry, ensure that the inlet scoop of the cover distal end that induced drafts has the same wind speed, be favorable to reaching ventilation effect with less convulsions volume, the appearance and the mounting dimension that have kept ventilation unit are unchangeable, adapt to newly-built or current systematic technological transformation, the apron has been cancelled, implement uncovered operation, and is simple in operation, and convenient for maintenance.
