Description
Technical field
The present invention relates to a kind of metal smelting device, specifically a kind of reductive jar for smelting magnesium metal.
Background technique
Reductive jar is the capital equipment of magnesium Metal Production, and mean level is mounted in reduction furnace, referred to as horizontal tank.Horizontal tank exists
Charge is few, feed the deficiencies of inconvenient, service life is short of slagging tap.In order to overcome horizontal tank disadvantages mentioned above, charge is big, can be automatic
Charging is slagged tap, the longer Vertical type reduction tank of service life is come into being, i.e., reductive jar is vertically installed in reduction furnace, referred to as perpendicular
Tank.A kind of entitled metal smelting Vertical type reduction tank of such as Patent No. 200510074923.2 and assembly of reduction furnace,
For another example the entitled a kind of reductive jar of metal smelting of Patent No. 200910254122.2 of the present inventor's invention, with horizontal tank
It compares, all has the characteristics that charging charge is big, service life is longer.But so far, existing magnesium metal smelt erects tank still
In the presence of charging, tapping operation is complicated, the recovery time is longer and production cost is higher the deficiencies of, to Smelting magnesium enterprise bring it is many not
Just.
Summary of the invention
Goal of the invention of the invention is to overcome defect present in background technique, thus realize it is a kind of charging, the side of slagging tap
Just quick, the reaction time is obviously shortened, and tank intensity is big, the reductive jar with long service life for smelting magnesium metal.
For achieving the above object, the technical scheme is that it is a kind of smelt magnesium metal reductive jar, including reduction
Tank body, the reduction tank body are hollow tubular structure, and the reduction tank base is in frustum-like shape, and restores tank base and be provided with
Slag notch；Heat-conducting plate is fixedly installed in the reduction inner tank wall, the reduction tank interior central part is movably set with cylinder
The diameter of the reduction gallbladder of shape, the reduction gallbladder is greater than the diameter of reduction tank base slag notch.
As the preferred technical solution of the present invention, vertical and circumference uniform distribution is solid on side wall in reductive jar body for the heat-conducting plate
Fixed setting, can be such that raw material is uniformly heated unanimously.
As the preferred technical solution of the present invention, the quantity of the heat-conducting plate is 4 ~ 50, and the height of heat-conducting plate is
10mm~200mm。
As the preferred technical solution of the present invention, the cross-sectional shape of the reduction gallbladder is circle, and restores the internal diameter of gallbladder
For 50mm ~ 400mm.
As the preferred technical solution of the present invention, restores and be provided with the recirculation hole that magnesium vapor passes through on the side wall of gallbladder, facilitate height
The magnesium vapor that temperature generates can be separated more smoothly from raw material, and recirculation hole circumference uniform distribution on reduction gallbladder side wall is staggeredly set
It sets, and recirculation hole is circular hole or strip-shaped hole.
The working principle of the reductive jar of smelting magnesium metal of the invention:
After restoring charging feedstock outside gallbladder in reductive jar body, with externally heated to reductive jar to 1200 DEG C left sides of reduction furnace
The right side, magnesium quilt when being evacuated to absolute pressure 100Pa or less from top to reduction tank body with vacuum pump, in reductive jar body in raw material
It restores, and the recirculation hole on reduction gallbladder is passed through with the state of steam and enters reduction gallbladder inner cylinder, eventually arrive at the top of reductive jar
Low-temperature space crystallize into solid-state magnesium；It after reduction reaction, uncaps and disposably mentions operation reduction gallbladder on the whole, will can quickly go back
Former slag is discharged from slag notch.
The reductive jar of smelting magnesium metal of the invention the utility model has the advantages that
1. the reductive jar of smelting magnesium metal of the invention, unique structure restore and are fixedly installed heat-conducting plate in inner tank wall,
Reduction gallbladder is the global facility that in tank and can move up and down, and overcomes the device being made of in the past multiple charging baskets,
The operation for enormously simplifying charging, slagging tap, while the high temperature open time for shortening reductive jar, avoid high-temperature oxydation and shortening makes
Use the service life.
2. the reductive jar of smelting magnesium metal of the invention, charge out magnesium, tank bottom of tank deck is slagged tap, and is arranged in reductive jar body
Heat-conducting plate is accelerated the endothermic process of the intracorporal material of reductive jar, is shortened also along the radial equipartition of the reduction inner tank wall
Original reaction time, improve production efficiency, at the same in reductive jar body longitudinal measure heat-conducting plate, make restore tank body intensity add
Greatly, service life is obviously prolonged.
