Description
Technical field
The utility model relates to a kind of non-ferrous metal metallurgy equipment art, particularly a kind of gasification feeding device that is used to produce Titanium Sponge 40-60 mesh.
Background technology
Titanium Sponge 40-60 mesh is the primary raw material in the Ti alloy, and it is the Kroll method that the main method of producing Titanium Sponge 40-60 mesh is gone up in industry at present, and this method is at first to utilize Mg and TiCl
4Reduction reaction generate Ti, remove excessive Mg, reaction product MgCl through vacuum distilling then
2With the little amount of titanium muriate, obtain spongiform titanium at last and stick together.
Large-scale 10 tons of reduction and distillation furnaces are main type of furnaces that the Kroll method is produced Titanium Sponge 40-60 mesh, but the Titanium Sponge 40-60 mesh produced of this type of furnace exists that center local superheating, spongeization rate are low, the densification of titanium piece is difficult to broken problem aborning.And be the important behave of the local agglomerating in center that sticks together of current domestic and international minimizing titanium through changing feed way.Application number is that 200620133754.5 Chinese patent has been introduced the titanium tetrachloride gasification installation that a kind of magnesium method is produced Titanium Sponge 40-60 mesh, and this device ultimate principle is to react uniformly with magnesium after utilizing the heat of molten metal bath magnesium that titanium tetrachloride is fully gasified again.Though the alleviation to a certain degree of this utility model liquid titanium tetrachloride at reactor center position and MAGNESIUM METAL 99 vigorous reaction; Help the raising of the quality product of Titanium Sponge 40-60 mesh; But still have following problem in actual use: necessarily expect under the fast situation (1); Because the heat transfer time is short, and TiCl can not be provided
4The required heat that is gasified totally, so gasification degree is low; (2) feeding device partly is inserted in the Mg melt, adds the rising of liquid level in the reinforced process, and the titanium piece that the filling tube pore volume is prone to generated stops up; (3) feeding device is near the reaction zone central position, and the filling tube end can be melted, and not only causes the Fe content overproof, and has lost gasification result.Therefore this utility model acquires a certain degree of difficulty in reality is promoted.
Application number is the titanium tetrachloride charging process that a kind of magnesium method that 200610051291.2 Chinese patent relates to is produced Titanium Sponge 40-60 mesh in addition; The ultimate principle of this method is: before titanium tetrachloride carries feeding tube to get into reactor drum, be provided with heating unit outside; Liquid titanium tetrachloride is through outside this during heating unit; Be heated to the above and gasification of boiling temperature, join in the reactor drum through the titanium tetrachloride filling tube, gasiform titanium tetrachloride and molten metal magnesium uniform contact are carried out reduction reaction.Though adopt this method that titanium tetrachloride is fully gasified, a significant drawbacks is arranged, be exactly because TiCl
4Being gasified totally needs a large amount of heat, and adopts the actual heat radiation load that has increased Reaktionsofen of external heat source gasification titanium tetrachloride, under the certain situation of heat radiation load, has not only increased energy consumption, has also limited the raising of material speed, has prolonged reduction cycle.
Application number is the titanium tetrachloride gasification process that a kind of magnesium method that 200610051187.3 Chinese patent relates to is produced Titanium Sponge 40-60 mesh; Wherein mention and utilize swirl nozzle formation mist droplet to be ejected on the MAGNESIUM METAL 99; Carry out reduction reaction, after this patent thought that titanium tetrachloride gasifies, the reduction reaction in the reactor drum was carried out equably; The situation of heat accumulation can not occur, thereby guarantee the quality product of Titanium Sponge 40-60 mesh.But in the actual use of this patent, only use swirl nozzle not scatter fully by titanium tetrachloride, and because the resistance of nozzle and pipeline expect that the fast upper limit receives than limitations.
Summary of the invention
The utility model technical problem to be solved provides a kind of gasification feeding device that is used to produce Titanium Sponge 40-60 mesh, utilizes this device can be so that TiCl
4Fully gasification can be avoided the existing problem of other gasification feeding devices simultaneously, and these problems comprise: titanium tetrachloride can not scatter fully, and gasification degree is low; Adopt external heat source gasification titanium tetrachloride to increase the heat radiation load of Reaktionsofen, also be unfavorable for energy-conservation; The filling tube pore volume is prone to stop up, and is prone to flame ablation at high temperature, thereby loses gasification result.
For the purpose that realizes solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of gasification feeding device that is used to produce Titanium Sponge 40-60 mesh; Be characterised in that: the gasification feeding device is uncovered disk-like structure; The bottom surface is processed by circular metal plate, the metallic ring-plate of 3-6 concentric(al) circles annular in the welding of circular metal panel area, and the inboard ring flat-plate height height of the ring flat-plate aspect ratio in the outside; The gasification feeding device is located on the big lid base plate of pyroreaction liquid level top in the reactor drum, is fixed by pull bar and big lid base plate.
Further, a kind of gasification feeding device that is used to produce Titanium Sponge 40-60 mesh of this patent is welded with gusset in the radial direction at the gasification feeding device.Further, the quantity of gusset is 4-12.
Through installing and fixing this gasification feeding device on the big lid base plate above the pyroreaction liquid level in reactor drum; The reaction heat that utilizes high temperature liquid level place heats the gasification feeding device through the mode of radiation and convection current, thereby makes the TiCl that is added on the gasification feeding device
4Gasification evenly gets into the gas-phase space on the reaction liquid level, at reaction liquid level place and liquid metal reactive magnesium.The metallic ring-plate of welding annular on the circular metal base plate, and the inboard ring flat-plate height height of the ring flat-plate aspect ratio in the outside can reach prolongation TiCl
4The technique effect of stop gasification time on the gasification feeding device; The gasification feeding device be welded with gusset in the radial direction, can reach the heating surface area that increases the gasification feeding device and the effect of intensity.
These technical schemes also can mutual combination perhaps combine, thereby reach better technique effect.
Through adopting technique scheme, the utlity model has following beneficial effect:
(1) reinforced through this gasification installation, gasification is abundant, and maximum can reach 100%;
(2) cost of manufacture is low, and is simple to operate;
(3) significantly reduced and contained sandwich magnesium chloride titanium piece amount in the product, made every stove contain sandwich magnesium chloride titanium piece amount and reduce to 20kg, improved product percent of pass 2.17% by 424kg;
