Abstract

The utility model provides a heating crucible for vacuum distillation stove, characterized by includes the crucible body, the crucible body in bottom center protruding, crucible center bellying is equipped with the steam conduit who link up from top to bottom along the crucible axis, the last port top surface height of steam conduit is shorter than crucible pot mouth edge top surface height, guarantees when a plurality of crucibles pile up together, metal steam in the crucible can flow into in the steam conduit through the steam conduit mouth of pipe rather than the space between the outer bottom surface of top crucible. Compared with the prior art, the utility model, adopt the heating crucible of unit formula, compare with single large-scale crucible of tradition, evaporation area increases substantially, can more effectively utilize the coil thermal field, avoids the reduction of evaporation remainder liquid level, and upper strata vacuole formation causes empty fever, and evaporation efficiency increases substantially for energy efficiency increases substantially.

Description

Heating crucible for vacuum distillation furnace

Technical Field

The utility model relates to the technical field of non-ferrous metal vacuum metallurgy equipment, in particular to a heating crucible for a vacuum distillation furnace.

Background

The main equipment used for realizing alloy vacuum distillation separation in the vacuum metallurgy industry is a vacuum distillation furnace, the limitation of materials processed by a general vacuum distillation furnace is large, and the specific alloy materials processed by a specific vacuum distillation furnace are generally processed, so that the research and development cost of the vacuum distillation furnace is high. The heating crucible generally used in the vacuum distillation furnace is an integral large crucible, the crucible is relatively thick, and the metal evaporation surface is only one surface, so that the evaporation area is greatly reduced, and the upper part of the crucible is easily subjected to idle burning.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide a heating crucible for a vacuum distillation furnace, which has wide applicability in the alloy vacuum distillation separation technology.

The technical scheme of the utility model as follows:

the utility model provides a heating crucible for vacuum distillation stove, characterized by includes the crucible body, the crucible body in bottom center protruding, crucible center bellying is equipped with the steam conduit who link up from top to bottom along the crucible axis, the last port top surface height of steam conduit is shorter than crucible pot mouth edge top surface height, guarantees when a plurality of crucibles pile up together, metal steam in the crucible can flow into in the steam conduit through the steam conduit mouth of pipe rather than the space between the outer bottom surface of top crucible.

The further scheme is as follows: the crucible body in still include a plurality of division boards, division board side end face and crucible body inner wall connect as an organic wholely, another side end face and steam conduit outer wall connect as an organic wholely, the bottom surface is connected as an organic wholely with crucible body inner bottom surface for divide into a plurality of equal parts with the annular cavity etc. between steam conduit and the crucible body inner wall, division board up end height be less than or equal to steam conduit upper end mouth top surface height, when guaranteeing to heat the crucible and piling up, leave the space between division board and the heating crucible outer bottom surface above it, can let the gas circulation, because the existence of division board simultaneously, in the remaining evaporation surplus condensation process in heating the crucible, can avoid evaporation surplus condensation annular shrink to damage the crucible.

The further scheme is as follows: the excircle of the upper end face of the pot mouth of the crucible body is provided with a circle of bosses, the excircle of the outer bottom face of the crucible body is provided with a circle of grooves matched with the bosses, and the bosses and the grooves can be matched with each other to be buckled and embedded when a plurality of crucible bodies are stacked, so that the stability of the heating crucibles during stacking is enhanced.

Compared with the prior art, the utility model, adopt the heating crucible of unit formula, compare with single large-scale crucible of tradition, evaporation area increases substantially, can more effectively utilize the coil thermal field, avoids the reduction of evaporation remainder liquid level, and upper strata vacuole formation causes empty fever, and evaporation efficiency increases substantially for energy efficiency increases substantially.

Detailed Description

The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.

Example 1

As shown in the figure, a heating crucible for vacuum distillation stove, includes crucible body 1, crucible body in bottom surface center protruding, crucible center bellying is equipped with along crucible axis steam conduit 2 that link up from top to bottom, steam conduit 2's last port top surface height is less than 1 pot mouth edge top surface height of crucible body, guarantees when a plurality of crucible bodies 1 pile up together, metal steam in crucible body 1 can flow into in steam conduit 2 through the space between 2 mouths of pipe of steam conduit and the outer bottom surface of its top crucible.

The crucible body 1 is internally provided with a plurality of partition plates 3, one side end face of each partition plate 3 is connected with the inner wall of the crucible body 1 into a whole, the other side end face of each partition plate is connected with the outer wall of the steam pipeline 2 into a whole, the bottom face of each partition plate is connected with the inner bottom face of the crucible body 1 into a whole and is used for equally dividing an annular cavity between the steam pipeline 2 and the inner wall of the crucible body 1 into a plurality of equal parts, the height of the upper end face of each partition plate 3 is the same as that of the top face of the upper port of the steam pipeline, so that when the heating crucibles are stacked, a gap is reserved between each partition plate 3 and the outer bottom face of the heating crucible body 1 above the partition plate, gas circulation can be realized, and meanwhile, due to the existence of.

Crucible body 1's pot mouth up end excircle be equipped with

round boss

4, 1 outer bottom surface excircle of crucible body is equipped with round and boss 4 matched with recess 5 for a plurality of crucible bodies 1 when piling up, boss 4 and recess 5 can mutually support to detain to inlay for strengthen the stability of heating crucible when piling up.
