Description
Technical field
The utility model relates to thick cadmium purification techniques field, particularly relates to a kind of condenser for thick cadmium vacuum distilling.
Background technology
There is no independent mineral deposit at nature cadmium, there is no the cadmium of simple substance yet.Cadmium is mainly with the form in fluidisation ore deposit and zinc ore, Pb-Zn deposits and copper/lead/zinc ore symbiosis, so in Zinc Hydrometallurgy Process, cadmium is enriched in copper-cadmium slag, in pyrometallurgical smelting of lead zinc process, cadmium is enriched in calcination fume, extracts thick cadmium through process copper-cadmium slag with containing lead-cadmium elimination roast flue dust.
Conventional is a vacuum distillation method by the method for thick cadmium production pure cadmium, and the equipment of application is mainly vacuum distillation furnace, and vacuum distillation furnace comprises the integral part such as evaporator room, condensing chamber.In order to improve the production efficiency of cadmium product as far as possible, inner chamber for the condenser of thick cadmium vacuum distilling has larger space usually, pass through to hold a large amount of cadmium vapor, but, when vacuum distillation furnace blow-on or blowing out, less by the cadmium vapor amount of condenser, the heat loss of cadmium vapor obtains comparatively fast, owing to only having very little temperature difference region from the boiling point (general control is at 430 DEG C) of cadmium under the fusing point 321 DEG C to vacuum state of cadmium, the cadmium vapor of the quick cooling condensator outlet place that is everlasting forms solid-state cadmium, cause line clogging, thus cleaning equipment is often needed, affect production efficiency.
In sum, line clogging becomes those skilled in the art's technical problem urgently to be resolved hurrily how to prevent the condenser for thick cadmium vacuum distilling from occurring.
Utility model content
In view of this, the utility model provides a kind of condenser for thick cadmium vacuum distilling, and this condenser effectively can prevent line clogging, is conducive to the production efficiency improving cadmium product.
In order to achieve the above object, the utility model provides following technical scheme:
For a condenser for thick cadmium vacuum distilling, comprising:
Inner casing, the described inner casing top steam be provided with for being communicated with evaporator room enters manages and the vacuum-pumping tube for being communicated with vacuum pump, and bottom is provided with cadmium liquid outlet pipe;
Be placed on the shell outside described inner casing, between the inwall of described shell and the outer wall of described inner casing, form cooling medium pass;
Near described cadmium liquid outlet pipe, paste the hot plate be layered on the outer wall of described inner casing.
Preferably, in above-mentioned condenser, the middle part of described inner casing is cylindrical, and two ends are semisphere.
Preferably, in above-mentioned condenser, the quantity of described hot plate is multiple, and multiple described hot plate is arranged along the even circumferential of described inner casing.
Preferably, in above-mentioned condenser, described hot plate surrounds a whole circle around described inner casing.
Preferably, in above-mentioned condenser, the middle part of described shell is cylindrical, and two ends are semisphere.
Preferably, in above-mentioned condenser, described shell is the drum of open topped, and described cadmium liquid outlet pipe runs through the bottom of described shell, and described shell is provided with air inlet port near the side of bottom.
According to technique scheme, in the condenser that the utility model provides, paste on the inner casing outer wall of cadmium liquid outlet pipe and be covered with hot plate, so when cadmium vapor flow is less, during as vacuum distillation furnace blow-on or blowing out, utilize hot plate to heat and cadmium vapor can be avoided because heat loss is too fast to form solid-state cadmium, thus effectively prevent cadmium liquid outlet pipe from occurring line clogging, therefore, the condenser that the utility model provides can reduce pipeline cleaning work, improves the production efficiency of cadmium product.
