Abstract
A left-side sublimation heating furnace used for purifying organic electroluminescence materials overcomes the defects that in the prior art, the right side of a heating furnace is a sublimation area, purification efficiency is low, vacuum degree of a vacuum system is affected, and a vacuum pump can be easily damaged when being used for a long time. The left-side sublimation heating furnace is characterized in that the left side of three heating areas inside the external heating electric furnace is a sublimation area, the middle and right sides of the three heating areas are depositional areas, the two ends of a middle material pipe and the two ends of a right material pipe are open, the left end of a left material pipe is sealed, and the right end of the left material pipe is open. The left-side sublimation heating furnace has the advantages that due to the fact that the left side is the sublimation area and the left end opening of the left material pipe is sealed, sublimation materials in a material boat are deposited towards the two deposition areas on the right side, under the air exhaust effect of a vacuumizing hose, surplus air flows rightwards through the right end opening of the left material pipe and the middle material pipe and the right material pipe communicated with the left material pipe and then flows leftwards in a space among the three material pipes and a liner pipe, and due to the fact that the length of the deposition area is doubled, adequate deposition of materials is guaranteed, the vacuum pump and a vacuum system are protected, and energy and sublimation materials are saved.
Description
Technical field
The utility model belongs to the vacuum sublimation purification furnace technical field, particularly for the left side of purification electroluminescent organic material distillation heating furnace.
Background technology
Vacuum sublimation purification principle is to utilize the vapour pressure that material produces under the vacuum heating conditions different, and the material steam that produces is separated by specific condensing mode.After the equipment requirement distillation district that is used for the purification electroluminescent organic material is heated to material gasification distillation, deposits to heat preservation zone and solidify, along with the heat preservation zone temperature is different, deposition materials purity is different, to reach the purification purpose.In the disclosed vacuum sublimation purification furnace of prior art, 3 thermals treatment zone of 3 corresponding heating furnaces of material pipe, the right side is the distillation district, left side and middle part are crystallizing field, the two ends of 3 material pipes all are uncovered, in the situation that does not also have fully to deposit at sublimator material, the part sublimator material is just taken away with air-flow, not only wasted effective useful resources, affect purification efficiency, and with the sublimator material that air-flow is taken away be deposited in the vacuum line and vavuum pump on, also affect the vacuum of vacuum system, the long-time vavuum pump that damages easily.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art part, provides a kind of sublimator material that can make fully to deposit, the left side distillation heating furnace that is used for the purification electroluminescent organic material that vacuum line and vavuum pump are shielded.
The technical solution adopted in the utility model comprises stand, left end support, external heat electric furnace, vacuumize flexible pipe, right-hand member support and play the Quartz stove tube of flue effect, left material pipe, middle material pipe and right material pipe are installed in Quartz stove tube, in left material pipe, the material boat is housed, described outer-heating electric furnace interior is divided into 3 thermals treatment zone, the left side is the distillation district, and middle part and right side are crystallizing field, and described middle material pipe and right material pipe two ends all are uncovered, described left material pipe left end sealing, right-hand member is uncovered.
Compared with prior art; the beneficial effects of the utility model are; because the left side is the distillation district; and left material pipe left end mouth of pipe sealing; sublimator material on the material boat is 2 crystallizing field depositions to the right; vacuumizing under the air-extraction function of flexible pipe; unnecessary gas by left material pipe right-end openings and be communicated with it in the middle of material pipe flow to the right first with right material pipe; flow to the left in space between 3 material pipes and bushing pipe again, extracts out through vacuumizing flexible pipe, because crystallizing field is equivalent to lengthen 1 times; both guaranteed that material fully deposited; improved deposition efficiency, had again the characteristics of protection vavuum pump and vacuum system, and then saved the energy and sublimator material.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure:
1. stand, 2. left end support,
3. the external heat electric furnace 4. vacuumizes flexible pipe,
5. Quartz stove tube, 6. bushing pipe,
7. left material pipe, 8. material boat,

11. the right-hand member support, 12. fire doors,
13. vent valve, 14. material pipe connecting rings.
The specific embodiment
As shown in drawings, the utility model has a stand 1, table top at stand 1 is equipped with left end support 2, vacuumize flexible pipe 4 and right-hand member support 11, external heat electric furnace 3 is installed on the table top between left end support 2 and the right-hand member support 11, a cylindrical hole is arranged in the middle of the external heat electric furnace 3, the Quartz stove tube 5 that plays the flue effect passes from this cylindrical hole, two ends, Quartz stove tube 5 left and right sides are supported and are clamped by left end support 2 and right-hand member support 11, described external heat electric furnace 3 inside are divided into 3 thermals treatment zone, the left side is the distillation district, middle part and right side are 2 crystallizing fields, play in the Quartz stove tube 5 of flue effect left material pipe 7 is installed, middle material pipe 9 and right material pipe 10, left material pipe 7 and middle material pipe 9, centre material pipe 9 and the material pipe 10 materials pipe connecting rings 14 of being connected connect, material pipe 9 and right material pipe 10 two ends all are uncovered in the middle of described, described left material pipe 7 left ends sealing, right-hand member is uncovered, material boat 8 is housed in left material pipe 7, the right-hand member of Quartz stove tube 5 is provided with fire door 12, at fire door 12 vent valve 13 is installed, bushing pipe 6 also is installed in Quartz stove tube 5.
The utility model distillation district is in the left side, sublimator material is put into material boat 8, material boat 8 is put into left material pipe 7, close fire door 12 and vent valve 13, vacuumize by vacuumizing flexible pipe 4, after vacuum reaches requirement, can begin heating, and at left material pipe 7 interior formation sublimator material gases, because the left end mouth of pipe of left material pipe 7 seals, sublimator material gas in the material boat 8 is by middle material pipe 9 and right material pipe 10 depositions, unnecessary sublimator material gas by right material pipe 10 right-end openings after, at left material pipe 7, space between middle material pipe 9 and right material pipe 10 and the bushing pipe 6 is mobile to left end, in flow process to the left, unnecessary sublimator material gas continues to be deposited on right material pipe 10 outsides expects pipe 9 outsides and manages 9 corresponding bushing pipe 6 inboards with right material pipe 10 and centre material with middle, finishes the material distillation and purifies.
