Problems solved by technology

[0002] Sponge zirconium is a metal zirconium production method that uses metal magnesium to reduce zirconium tetrachloride to produce sponge zirconium through the Krall method. The reduction product is separated by zirconium vacuum distillation to remove other Sponge zirconium can be obtained after the composition. The reduction furnace is a column cylinder welded by stainless steel plates. According to the ZrCl4 addition method, it can be divided into two different furnace types: one-time feeding and continuous feeding. The one-time feeding reduction furnace consists of reduction The magnesium ingot is pre-installed in the reaction crucible in the reduction furnace, the center of the sleeve above the crucible is a ZrCl4 gas conduit, and the volatilization furnace with ZrCl4 is placed on the reduction furnace. The furnace cover is connected with the vacuum system and the gas charging system, and the MgCl2 melt produced by the reaction is discharged from the furnace regularly through the flow tube, and the remaining MgCl2 at the end of the reduction can be exhausted from the discharge tube, and the product is taken out together with the reaction increase end after cooling Vacuum distillation, the production capacity of a single furnace of this reduction furnace is 700-800kg tons of zirconium sponge, the operation cycle is 48h, and the utilization rate of magnesium is 68%-72%. The passage pipes are connected, and the passage pipes often need to be disassembled for cleaning after restoration. Most of the existing flanges are connected by bolts and nuts. Although the structure is simple and stable, the frequent dismantling It is very inconvenient to install, and after the flange is heated, it will produce stress deformation and squeeze the bolts and nuts, resulting in more laborious screwing of the nuts and even slippery wires

Abstract

The invention provides a convenient-to-disassemble and assemble aisle device for a zirconium sponge reduction furnace, and belongs to the technical field of sponge zirconium production. The aisle device comprises a reduction furnace, an aisle pipe, a first flange and a second flange, the second flange is fixedly connected to the lower portion of the right side of the reduction furnace, the first flange is fixedly connected to the right side of the second flange through bolts, the right side of the first flange is fixedly connected with an aisle pipe, and fixing screw holes are formed in holes of the first flange and the second flange. According to the convenient-to-disassemble and assemble aisle device for the zirconium sponge reduction furnace, first magnets and second magnets are arranged, the principle that like poles of permanent magnets repel and unlike poles attract is utilized, when an inclined plate moves upwards and is in the same level with the first magnets, the two first magnets with like poles repelling repel each other, and the inclined plate pushes a movable plate more stably; and when the inclined plate moves downwards to the positions of the second magnets, the inclined plate and the second magnets are attracted under the principle that unlike poles attract, and the inclined plate drives the movable plate to move rightwards, so that a clamping and fixing rod is quickly separated from an embedding groove.

Description

technical field [0001] The invention relates to the technical field of zirconium sponge processing, more specifically, to a zirconium sponge reduction furnace. Background technique [0002] Sponge zirconium is a metal zirconium production method that uses metal magnesium to reduce zirconium tetrachloride to produce sponge zirconium through the Krall method. The reduction product can be obtained by zirconium vacuum distillation and separation to remove other components. Sponge zirconium is obtained. The reduction furnace is a stainless steel plate The welded column cylinder can be divided into two different furnace types: one-time feeding and continuous feeding according to the ZrCl4 adding method. The one-time feeding reduction furnace is composed of a reduction furnace and a volatilization furnace connected to it with a flange. Installed in the reaction crucible in the reduction furnace, the center of the sleeve above the crucible is the ZrCl4 gas conduit, the volatilizatio...
