Abstract

The utility model provides a heating type reactor large cover, which comprises a cover body. A guide tube is arranged in the cover, the upper end of the guide tube is communicated with a reduction distillation reactor through a connecting pipe, the lower end of the guide tube is communicated with a condensing reactor, and the periphery of the guide tube is provided with a plurality of groups of annular heating elements through a plurality of heat resistant insulation layers. The heating type reactor large cover is characterized in that heat radiation holes are arranged on the heat resistant insulation layers below the annular heating elements. The heating type reactor large cover greatly reduces blockage of the lower portion of the guide tube of the reactor large cover, improves separation effects of impurities such as titanium sponge, magnesium chloride, metal magnesium and the like, greatly reduces times for manually dredging the guide tube and changing the heating type reactor cover, reduces labor strength, reduces maintenance cost, shortens production cycle, reduces secondary pollution of titanium sponge products, and ensures the quality of the titanium sponge products. Simultaneously, the heating type reactor large cover effectively avoids contact between the heating elements and the fallen scale on the outer wall of the guide tube and protects the heating elements from being damaged due to a short circuit or a broken circuit.

Description

The big lid of heating-type reactor

Technical field

The utility model relates to the big lid of a kind of heating-type, especially a kind ofly produces the used big lid of heating-type reactor of titanium sponge with the inverted U integrated process, belongs to evaporative condenser heating unit manufacturing technology field.

Background technology

Produce in the process of titanium sponge in the inverted U integrated process, after the reduction reaction of MAGNESIUM METAL and titanium tetrachloride finished, also residual in the titanium sponge in the reduction distillation reactor had part magnesium chloride and MAGNESIUM METAL impurity.For titanium sponge is separated and purified to this part impurity from titanium sponge, the reduction distillation reactor that fills titanium sponge is docked with condensation reactor, under the vacuum distilling state, the big lid of carrying pipe is sent into impurity such as magnesium chloride and MAGNESIUM METAL and is carried out condensation-crystallization in the condensation reactor on the process condensation reactor, obtain purified titanium sponge, the magnesium chloride of recyclable condensation-crystallization and MAGNESIUM METAL on the other hand on the one hand.In big lid skirt, stop up skirt behind the condensation-crystallization for preventing gaseous state magnesium chloride and MAGNESIUM METAL, thereby influence separating of gaseous state magnesium chloride and MAGNESIUM METAL and titanium sponge, prior art is the refractory insulating layer of setting up electric heater in the skirt periphery and supporting electric heater, to constitute the big lid of heating.But the big lid of existing heating can only heat the catheter wall in the big lid, heat energy effectively can't be radiated to the conduit lower end, make gaseous state magnesium chloride and MAGNESIUM METAL easily at big lid conduit lower end condensation-crystallization, in case and crystal growth, will stop up conduit from bottom to top and influence the vacuum distilling separation, thereby reduce the titanium sponge quality product, extend manufacture cycle, increase production cost.In addition; because the heating unit that is installed in the big lid is all exposed outside; there is not any sfgd.; when the iron scale of conduit outer wall in the big lid drops on the heating unit; easily cause and cause short circuit or open circuit; even cause the damage of heating unit, thereby shorten heating unit work-ing life, increase maintenance cost, extend manufacture cycle.Therefore be necessary prior art is improved.

Summary of the invention

Can't implement heating to the conduit bottom for solving the big lid of existing heating, make gaseous state magnesium chloride and MAGNESIUM METAL easily at conduit bottom condensation-crystallization, final influence effectively separating of impurity such as titanium sponge and magnesium chloride and MAGNESIUM METAL, and the oxide compound that come off easily of heating unit causes short circuit or opens circuit and cause the problem of damage that the utility model provides a kind of heating-type reactor big lid.

The utility model is finished by following technical proposal: the big lid of a kind of heating-type reactor, comprise the lid of establishing conduit in it, the upper end of conduit is communicated with the reduction distillation reactor by pipe connecting, the lower end of conduit is communicated with condensation reactor, the conduit periphery is provided with the annular heating unit of many groups by multi-layered thermal insulation layer, the heat-resisting thermal insulation layer that it is characterized in that annular heating unit below is provided with heat radiation holes, so that by heat radiation holes with the thermal energy transfer of heating unit to big lid bottom, prevent gaseous state magnesium chloride and MAGNESIUM METAL condensation-crystallization and stop up conduit below big lid conduit.

Described heat radiation holes is disposed on heat-resisting thermal insulation layer annular recesses bottom, and vertical with annular recesses, so that by vertical a plurality of heat radiation holes heat energy is transmitted vertically downward, until being delivered to big lid bottom.

The vertical heat radiating aperture of described heat-resisting thermal insulation layer annular recesses bottom, its upper end is communicated with annular recesses, and the lower end is communicated with adjacent heat-resisting thermal insulation layer annular recesses.

Described annular heating unit is socketed with the heat conduction protective sleeve outward, in the time of by heat conduction protective sleeve transferring heat energy, effectively avoids heating unit to contact with the conduit outer wall iron scale that comes off, the protection heating unit not because of short circuit, open circuit and damaged.

The utlity model has following advantage and effect: adopt such scheme, reduced the obstruction of the big lid conduit of reactor bottom significantly, separate impurities effects such as titanium sponge and magnesium chloride and MAGNESIUM METAL have been improved, greatly reduce the number of times of artificial mediation conduit and the big lid of replacing heating-type, reduced labour intensity, reduced maintenance cost, shorten the production cycle, realized saving energy and reduce the cost, and greatly reduced the secondary pollution of titanium sponge product, guaranteed the titanium sponge quality product; Simultaneously effectively avoid heating unit to contact with the conduit outer wall iron scale that comes off, protect heating unit not because of short circuit, open circuit and damaged.The utlity model has simple in structure, fitting operation convenience, the advantage that result of use is good.
