Abstract
The utility model relates to an inner heating furnace of equipment for purifying an organic electroluminescent material, which solves the technical problem that in the prior art, the distance from the thermocouple of an outer electric heating furnace to an electric heating wire on the body of the electric heating furnace is larger, the measured temperature cycle of the thermocouple is longer, and temperature overcharge is easy to generate, and thereby, material sublimation is influenced. The inner heating furnace is characterized in that a cylindrical through hole is arranged in the middle of the outer electric heating furnace; a quartz furnace tube taking the effect of the furnace pipe of the inner heating furnace passes through the through hole; the inner heating furnace comprising the electric heating wire support, the electric heating wire and the thermocouple is arranged in the quartz furnace tube; the right end of the quartz furnace tube is provided with a furnace door; the furnace door is provided with a heating electrode, a thermocouple electrode and an air tube; the left end of the air tube is connected with a material boat; and the right end thereof is connected with an air-release valve. The utility model has the advantages that the thermocouple and the electric heating wire are nearer to the material boat and can directly carry out heating and temperature control on the material boat, whereas the phenomenon of temperature overcharge can not be generated so that the material sublimation temperature is ensured and the inner heating furnace has the characteristics of high temperature rise speed and high heating efficiency, and thereby, the energy sources are saved.
Description
Technical field
The utility model belongs to vacuum sublimation purification furnace technical field, particularly a kind of internally heated oven of the electroluminescent organic material equipment that is used to purify.
Background technology
Vacuum sublimation purification principle is to utilize the vapour pressure difference that material produces under the vacuum heating conditions, and the material steam of vapour pressure is separated by specific condensing mode.After the equipment of electroluminescent organic material of being used to purify requires the distillation district to be heated to material gasification distillation, deposit to heat preservation zone and solidify, along with the different deposition materials purity of heat preservation zone temperature difference to reach the purification purpose.The disclosed a kind of vacuum sublimation purification furnace of prior art such as ZL200720038758.X, this vacuum sublimation purification furnace comprise body of heater and the flue that places in the body of heater, and described subliming furnace body of heater is the electrical heating body of heater, and promptly the electricity consumption heating furnace body heats the distillation flue.This structure belongs to external heating mode, shown in ZL200720038758.X patent specification accompanying drawing, its thermocouple is contained on the fire door of sublimation chamber, heating wire distance on thermocouple and the electric furnace body of heater is far away, be again vacuum state in the flue, the heat conduction is slower, and the temperature cycle that thermocouple records is longer, be easy to generate temperature and overcharge, thereby influence the material distillation.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art part, provide a kind of in mode of heating be used to purify the internally heated oven of electroluminescent organic material equipment, realize that thermometric detects accurately and the phenomenon of avoiding temperature to overcharge.
The technical solution adopted in the utility model comprises a stand, the left end support is installed on the table top of stand, vacuumize flexible pipe and right-hand member support, be equipped with on the table top between left end support and the right-hand member support and add electrothermal stove, in the middle of adding electrothermal stove a cylindrical hole is arranged, the Quartz stove tube that plays the effect of internally heated oven flue passes from this cylindrical hole, two ends, the Quartz stove tube left and right sides are by left end support and right-hand member stent support and clamping, the described electrothermal stove right-hand member that adds is the distillation district, middle part and left end are crystallizing field, play in the Quartz stove tube of internally heated oven flue effect and be equipped with by the electrothermal wire rack, the internally heated oven that heating wire of installing in the electrothermal wire rack and thermocouple are formed, the right-hand member of Quartz stove tube is provided with fire door, heating electrode is installed on fire door, thermocouple electrode and tracheae, the tracheae left end is connected with the material boat of placing sublimator material, and the tracheae right-hand member is connected with vent valve.
The utility model beneficial effect compared with prior art is, owing to adopt internally heated oven, thermocouple and heating wire are nearer apart from the material boat, internally heated oven can directly heat temperature control to the material boat, can not produce the phenomenon that temperature overcharges, both guarantee the material sublimation temperature, it is fast to have programming rate again, the characteristics that the efficiency of heating surface is high, thus the energy and sublimator material saved.
