Abstract
The invention discloses an observation window structure for an organic light emitting material sublimation purification device, and overcomes the problems that a furnace body of an external heating furnace of the organic light emitting material sublimation purification device can only be provided with a plurality of discontinuous small observation windows so as to cause incomplete observation of the heating condition of a sublimation region and a deposition region in the heating furnace, low working efficiency and energy waste in the prior art. The observation window structure is characterized in that an electric heating wire and a horizontal wire are wound in an insulating bracket in parallel; one or two sides of the furnace body of the external heating furnace are provided with an oblong observation window and at least one transparent glass layer; and the inner surface of the transparent glass is coated with a metal film layer with infrared reflectivity of between 40 and 80 percent. The observation window structure has the advantages of observing the sublimation and deposition conditions of the material in the heating furnace during work, adjusting the temperature at any time, timely stopping heating when the sublimation of the material at the sublimation region is observed to be finished, preventing energy waste, reflecting the heat back into the heating furnace to conduct a heat preservation function, keeping the heating temperature in the furnace uniform and improving the machining efficiency and the machining quality.
Description
Technical field
The invention belongs to vacuum sublimation purification furnace technical field, particularly a kind of window structure of luminous organic material sublimation purification device.
Background technology
In the prior art, the luminous organic material sublimation purification device comprises internally heated oven and externally heated oven, and flue, bushing pipe and material pipe are installed between internally heated oven and externally heated oven; Said externally heated oven is made up of insulation material and electrical heating wire, forms three thermals treatment zone, and one of them is the distillation district; Two other is a crystallizing field; Be provided with insulating support in distillation district with crystallizing field, said electrical heating wire is vertical with horizontal line radially to be wound on the insulating support external diameter, can only offer that several are interrupted and less visual windows at the gap location between the electrical heating wire radially on the feasible heating furnace body outside of this structure; The heating state of distillation district in the heating-furnace and crystallizing field is observed not exclusively; Can only behind end-of-job, internally heated oven and material pipe be extracted out, whether observation distillation situation is complete.The existing technical problem of this window structure, the one, need extract internally heated oven out back with the material pipe and observe, if distillation not exclusively, needs distillation again; The 2nd, the distillation of material boat sublimator material finishes, but does not observe, and heating work is also continuing.Since the existence of the problems referred to above, inefficiency, and waste energy.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the weak point of prior art, provide a kind of can the complete observation heating furnace in a kind of window structure of luminous organic material sublimation purification device of distillation district and crystallizing field duty.
The technical scheme that the present invention taked comprises the externally heated oven of being made up of insulation material and electrical heating wire; In three thermals treatment zone of externally heated oven, all be provided with insulating support; Said electrical heating wire and horizontal line parallel, horizontal are wound in the insulating support of each thermal treatment zone; Offer a rectangle visual windows that covers three thermals treatment zone in the body of heater one or both sides of externally heated oven; On the body of heater of the outside of rectangle visual windows, the form support is installed, layer of transparent glass is installed in the form support at least.
Scribbling the infrared reflecting rate at the inner surface of clear glass is 40%～80% metallic diaphragm.
The beneficial effect that the present invention compared with prior art produces is:
1. because a complete rectangle visual windows that covers three thermals treatment zone is set; Can when work, observe material distillation and deposition conditions in the heating furnace through the rectangle visual windows; At any time carry out the temperature adjustment; When the material distillation of observing the distillation district finishes, can in time stop heating, avoided energy waste.
2. owing to clear glass is installed and is scribbled the infrared reflecting metallic diaphragm, reflect heat is got back in the heating furnace, can play insulation effect, make in the stove heating-up temperature even, improved working (machining) efficiency and quality at the inner surface of clear glass in visual windows.
