Embodiment
Present embodiment is that example describes with the production MAGNESIUM METAL.As shown in Figure 1, the upper and lower part that is vertically mounted on the reduction jar 3 in the process furnace stretches out at the bottom of process furnace furnace roof 4 and the heating-furnace 6 respectively, and the middle portion of reduction jar is in the process furnace and is heated.In reduction jar 3 upper ends preheating storage bin 2 is installed, the discharge port of preheating storage bin links with the upper end sealing and fixing of reduction jar 3, on the reduction jar between preheating storage bin 2 and the process furnace furnace roof 4, be installed with MAGNESIUM METAL crystallizer 17, on MAGNESIUM METAL crystallizer 17, be fixed with the Link Port 18 that links to each other with vaccum-pumping equipment.The external stability of the lower end extension of reduction jar 3 is equipped with bracing frame 16, and the reduction jar links to each other with the furnace bottom 6 of process furnace by bracing frame 16; The upper end of the discharge nozzle 8 of band cooling jacket links to each other with a reduction jar lower end sealing, but the lower end of discharge nozzle 8 is equipped with the drawing mechanism of open and close, this device is by forming by hinge 15 hinged outer gland sealing plate 12 and interior blocking material plate 9 with discharge nozzle 8 is outside, interior blocking material plate 9 is hinged by hinge 14 and discharge nozzle 8 inwalls, interconnects by being fixedly mounted on hinge on outer gland sealing plate and the interior blocking material plate and the connecting rod 13 that links to each other with two hinges respectively between outer gland sealing plate 12 and the interior blocking material plate 9.
The turnover panel 19 that discharge port is opened and closed is installed in the discharge port of preheating storage bin 2, and turnover panel 19 is connected through the hinge at the discharge port inwall.Turnover panel 19 is in vertical unlocking position as shown in Figure 1, and during dotted line position among Fig. 1, material enters in the reduction jar by the preheating storage bin.When material installs to design flow, turnover panel 19 is turned to horizontal closed position, then with opening for feed sealing plate 1 and opening for feed sealing and fixing.
During reaction, the outer gland sealing plate 12 of reduction jar lower end passes through sealing member 10 hermetic seals with the end of discharge nozzle 8, and blocking material plate 9 is in horizontal closed position shown in Figure 1 in the while.The reduction jar vacuumizes by Link Port 18, makes the reduction jar carry out reduction reaction under vacuum.Shown in Fig. 2,3, owing to be fixed with metallic vapor recovery tube 3-1 in the inner chamber of reduction jars 3, recovery tube 3-1 is fixed in the reduction jar by fixing gusset 3-2, has to be used to make the metal that is reduced out to enter the recovery holes 3-3 of recovery tube on recovery tube.Fixedly the quantity of gusset 3-2 can design according to the size of throughput.The quantity of the fixedly gusset of present embodiment is 3, and the inner chamber that so just will reduce jar is divided into three relatively independent chamber 3-4.Because after the outer wall of reduction jar heated by process furnace, heat rapidly to a reduction jar internal delivery, also can rise the temperature of charge in reduction jar interior centre by fixing gusset rapidly, can effectively reduce the heat-up time of material.After the MAGNESIUM METAL steam that is reduced overflows, enter by recovery holes 3-3 among the recovery tube 3-1 at reduction jar lumen centers position, enter in the crystallizer in the reduction jar by recovery tube and carry out crystallization.Because the existence of recovery tube, can effectively reduce the MAGNESIUM METAL steam and enter resistance in the crystallizer, improved the rate of recovery and the crystallization time of reduction jar.
Reaction is opened the outer gland sealing plate by the handle 11 that is fixed on the outer gland sealing plate after finishing, because the effect of connecting rod 13, interior blocking material plate is opened simultaneously in company with the outer gland sealing plate, and reacted waste residue flows out the discharge port of reduction jar bottom along interior blocking material plate.Because the effect of blocking material plate, the waste residue that has a certain temperature not with the outer gland sealing plate on contact with the discharge nozzle end cross-sectional sealing member 10 that matches, prolonged the work-ing life of sealing member.
In order further to reduce the drop temperature of waste residue, cooling jacket 7 is installed on discharge nozzle 8.
When discharging, not that reaction residues is all got rid of, but kept a part of reaction residues in the discharge nozzle of reduction jar.According to the character and the processing condition of reducing metal, the amount that keeps reaction residues is more than or equal to 1/8 of the material total amount of adorning in the reduction jar, smaller or equal to 1/3 of total amount, decrease of temperature speed slowed down.
After discharging finishes, with the outer gland sealing plate 12 of reduction jar lower end and the end hermetic seal of discharge nozzle 8, the turnover panel 19 that will be fixed on then on the discharge port of preheating storage bin 2 of reduction jar upper end is opened, be contained in the interior material of preheating storage bin and enter in the reduction jar, because the material in the reduction jar heats the material in the preheating storage bin when reacting, after this material enters the reduction jar, by the process furnace heating, can reach the temperature of reduction reaction soon, saved the heating-up time and the required energy of heating.The heating energy source of process furnace can be coal, combustion gas, electric energy equal energy source.
The lower surface and the horizontal plane of discharge nozzle acutangulate, and this acute angle is preferably 30-48 °.
