Abstract
Description
Technical Field
[0001] This utility model relates to the field of material heating and purification technology, and in particular to a purification and collection device. Background Technology
[0002] Organic electroluminescent materials are used in the manufacture of organic electroluminescent (OLED) displays. The performance of organic electroluminescent materials has high requirements for the cleanliness of the manufacturing environment and the stability of the production process. In the existing technology, the purification of organic electroluminescent materials generally involves placing the raw materials in a quartz glass tube carrier and heating them under high vacuum for purification.
[0003] In high-vacuum heating purification processes, organic electroluminescent material raw materials are placed into the purification equipment, and the material collection carrier of the purification equipment is generally a quartz glass tube. The quartz glass tube includes a feeding tube and a collecting tube. After heating, the organic electroluminescent material undergoes a phase change. In the feeding tube, the organic electroluminescent material becomes gaseous. Under thermodynamic forces, it moves to the collecting tube, cools into a solid state, and is then collected. However, the organic electroluminescent material generates stress upon heating, which is released during cooling. If this stress release is intense, it may cause the solid material to shatter and splatter, damaging the quartz glass tube carrier and leading to cross-contamination of the purified organic electroluminescent material. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a purification and collection device. During the cooling process of organic material gas, some organic material solids adhere to the surface of the collection component, reducing the amount of organic material solidifying at the bottom of the collection chamber. The collection component helps to increase the stress contact area of the organic material solids, disperse the stress release, reduce the stress on the cooling collection container, avoid the cracking and splashing phenomenon caused by the stress release of organic material solids at the bottom of the collection chamber, and prevent the cooling collection container from breaking.
[0005] The purification and collection apparatus according to an embodiment of the present invention includes:
[0006] The feeding container is equipped with a feeding chamber;
[0007] A heater is used to heat the feeding chamber;
[0008] A cooling collection container is provided with a collection chamber, which is connected to the feeding chamber;
[0009] A collection element is disposed at the bottom of the collection chamber, which divides the collection chamber into several areas. The surface of the collection element and the inner wall of the collection chamber serve as the contact surface for material adhesion.
[0010] The purification and collection device according to the embodiments of this utility model has at least the following beneficial effects: After organic material raw materials are added to the feeding chamber of the feeding container, the organic material raw materials in the feeding chamber are heated by a heater to transform them into organic material gas. Then, the organic material gas flows into the collection chamber of the cooling collection container due to thermal action. The cooling collection container cools the organic material gas, causing it to condense into organic material liquid. The organic material liquid solidifies into organic material solid at the bottom of the cooling collection container. The surface of the collecting element and the inner wall of the collection chamber serve as the contact surface for the organic material solid to adhere, thus the organic material solidifies at the bottom of the collection chamber and is collected. The surface of the collecting element is designed to facilitate the collection of organic solids. The collecting element divides the collecting chamber into several regions, where the organic material solidifies, thereby reducing the crystal volume of the organic solids and dispersing the stress release of the organic solids. During the cooling process of the organic gas, some organic solids adhere to the surface of the collecting element, reducing the amount of organic material solidifying at the bottom of the collecting chamber. The collecting element helps to increase the contact area between the organic solids and the collecting chamber, disperse the stress release, reduce the stress on the cooling collecting container, and prevent the cracking and splashing phenomenon caused by the stress release of the organic solids at the bottom of the collecting chamber, thus preventing the cooling collecting container from breaking.

[0030] In the description of this utility model, it should be noted that terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0031] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.
[0032] Reference Figures 1 to 7 As shown, this embodiment of the present invention provides a purification and collection device.
[0033] The purification and collection device includes a feeding container, a heater, a cooling collection container 100, a collection chamber 110, and a collection component 200.
[0034] The feeding container is equipped with a feeding chamber. A heater is used to heat the feeding chamber of the feeding container. Organic raw materials are fed into the feeding chamber, and the heater is used to heat the organic raw materials in the feeding chamber, so that the organic raw materials are converted into organic gas.
[0035] The cooling collection container 100 is provided with a collection chamber 110, which can be arranged in any direction, such as vertical or horizontal. The collection chamber 110 has connecting holes on two opposite side walls in the horizontal direction. One connecting hole on one side of the collection chamber 110 connects to the feeding chamber, and the other connecting hole connects to the vacuum device. The vacuum device evacuates the collection chamber 110, so that the organic material is purified in a vacuum environment, and the organic material gas moves from the feeding chamber to the collection chamber 110.
[0036] Of course, the collecting cavity 110 can also be set in a way that is inclined in the horizontal direction or inclined in the vertical direction, and the same technical effect described in this utility model can be achieved.
[0037] The collecting component 200 is disposed in the collecting cavity 110. The collecting component 200 is disposed in the collecting cavity 110 in any direction. In the following embodiments, the disposal direction of the collecting component 200 is the preferred option. Other disposal directions not mentioned can also achieve the technical effects described in this utility model.
[0038] Reference Figures 1 to 2 As shown, the collection chamber 110 is arranged in a horizontal direction. The collection chamber 110 has through holes on two opposite side walls in the horizontal direction. One through hole of the collection chamber 110 is connected to the feeding chamber of the feeding container, and the other through hole of the collection chamber 110 is connected to the vacuum device. The organic material gas generated in the feeding chamber is transferred to the collection chamber 110 due to the thermal effect. The organic material gas is cooled down in the collection chamber 110 with a lower temperature, so that the organic material gas is transformed into organic material liquid and solidified into organic material solid at the bottom of the collection chamber 110.
[0039] It is understandable that the cooling measures of the cooling collection container 100 can be natural cooling or cooling by using cooling equipment, so that the organic material gas can be cooled down in the collection chamber 110.
[0040] In this embodiment, the collection chamber 110 is provided with a first impurity collection area, a product collection area, and a second impurity collection area. The cooling collection container is provided with the first impurity collection area, the product collection area, and the second impurity collection area in sequence from the feeding chamber toward the vacuum device. The temperature of the first impurity collection area is higher than the temperature of the product collection area, and the temperature of the product collection area is higher than the temperature of the second impurity collection area. The lengths of the first impurity collection area, the product collection area, and the second impurity collection area can be customized according to the usage requirements of different purification and collection devices.
[0041] This structure achieves efficient separation of impurities from the target product. The product collection zone is located between the two impurity collection zones, avoiding contamination of the target product by impurities and improving product purity. The temperature gradient design ensures that different substances condense in different areas, optimizing the condensation process and reducing secondary contamination. The length of each zone can be customized according to actual needs, enhancing the flexibility and applicability of the device, thereby improving overall purification efficiency and product quality.
[0042] In this embodiment, the collection component 200 is disposed in the product collection area.
[0043] Reference Figures 3 to 7As shown, the collector 200 is located at the bottom of the collection chamber 110. Specifically, the collector 200 is located at the bottom of the product collection area. During the cooling process of the organic material gas in the collection chamber 110, the organic material gas first condenses into organic material liquid. The organic material liquid is collected at the bottom of the collection chamber 110 due to gravity. Some of the organic material liquid adheres to the surface of the collector 200. As the temperature continues to drop, the organic material solidifies on the surface of the collector 200.
[0044] Organic materials solidify at the bottom of the collection chamber 110 and on the surface of the collection component 200 to facilitate the collection of organic material solids. During the cooling process of the organic material gas, since some organic material solidifies on the surface of the collection component 200, the amount of organic material solidifying at the bottom of the collection chamber 110 is reduced. The collection component 200 helps to increase the contact area between the organic material solids and the collection chamber 110, disperse the release of stress, reduce the stress on the cooling collection container 100, avoid the cracking and splashing phenomenon caused by the stress release of organic material solids at the bottom of the collection chamber, and prevent the cooling collection container 100 from breaking.
[0045] It is understood that the shape of the collection component 200 includes, but is not limited to, fixed mesh grilles, strip partitions, perforated partitions, vertically arranged partitions, wavy partitions, and easily deformable soft components.
[0046] The material of the collecting component 200 includes, but is not limited to, heat-resistant materials such as stainless steel and quartz glass. The heat resistance temperature of the collecting component 200 is greater than the heating and purification temperature of the organic material, and the collecting component 200 does not react chemically with the organic material. In this embodiment, the heat resistance temperature of the collecting component 200 is greater than 400°C, and the organic material is an organic electroluminescent small molecule material.
[0047] The placement methods for the collection component 200 include, but are not limited to, quartz welding, stainless steel welding, and manual assembly.
[0048] according to Figure 3 and Figure 4 As shown, in the first and second embodiments of the collecting member 200, the collecting member 200 has a vertically arranged partition plate structure, and the collecting member 200 is vertically arranged relative to the bottom of the collecting cavity 110.
[0049] Reference Figure 3As shown, in the first embodiment of the collecting member 200, the collecting member 200 has a vertically arranged partition plate structure, the collecting cavity 110 is arranged in a horizontal direction, the length direction of the collecting member 200 is perpendicular to the setting direction of the collecting cavity 110, and the width direction of the collecting member 200 is parallel to the setting direction of the collecting cavity 110. A reinforcing block 201 is provided on each of the two side walls of the collecting member 200, and the bottom of the reinforcing block 201 abuts against the bottom of the collecting cavity 110. In some embodiments, the collecting cavity 110 is provided with a plurality of collecting members 200, and the collecting members 200 are distributed sequentially at intervals along the setting direction of the collecting cavity 110.
[0050] Reference Figure 4 As shown, in the second embodiment of the collecting member 200, the collecting member 200 has a vertically arranged partition plate structure, the collecting cavity 110 is arranged horizontally, the length direction of the collecting member 200 is parallel to the setting direction of the collecting cavity 110, the width direction of the collecting member 200 is perpendicular to the setting direction of the collecting cavity 110, and multiple collecting members 200 are distributed at intervals along the setting direction perpendicular to the setting direction of the collecting cavity 110, and the collecting members 200 extend along the setting direction of the collecting cavity 110. It can be understood that in some embodiments, the collecting member 200 has a reinforcing block 201 on each of its two opposite sidewalls, and the bottom of the reinforcing block 201 abuts against the bottom of the collecting cavity 110. This helps to distribute the pressure borne by the collecting member 200, avoid stress concentration, and thus improve the durability and reliability of the device.
[0051] The collecting component 200 is vertically arranged relative to the bottom of the collecting chamber 110, and the collecting component 200 is plate-shaped, which helps the organic material solidify on the surface of the collecting component 200, reduces the organic material solidification on the bottom wall of the collecting chamber 110, and utilizes the collecting component 200 to bear the stress released by the organic material solid, which greatly reduces the stress released by the organic material solid to the cooling collecting container 100.
[0052] Furthermore, when the collecting component 200 is a strip-shaped partition or a partition with holes, both ends of the bottom of the collecting component 200 have reinforcing blocks 201 to make it easier to place vertically on the bottom wall of the collecting cavity 110.
[0053] In some embodiments, refer to Figures 3 to 4 As shown, the ratio of the vertical height of each collector 200 to the vertical height of the collection cavity 110 ranges from 1:2 to 1:3.
[0054] The height of the collecting element 200 is 1 / 3 to 1 / 2 of the height of the collecting cavity 110, so as to avoid the collecting element 200 from obstructing the organic material gas that diffuses in the collecting cavity 110 under the action of heat, and to make the organic material solid condense evenly on multiple collecting elements 200.
[0055] In some embodiments, refer to Figures 5 to 6As shown, the collector 200 is provided with a curved portion 202 that bends along the thickness direction. There may be one or more curved portions 202, and the multiple curved portions 202 are distributed at intervals along the length direction of the collector 200.
[0056] The collecting component 200 is provided with a curved portion 202. Within the limited volume space of the collecting cavity 110, the collecting component 200 increases its surface area by bending and folding. Organic materials solidify on the surface of the collecting component 200, reducing the amount of organic materials solidifying at the bottom of the collecting cavity 110. The collecting component 200 helps to increase the contact area between the organic material solid and the collecting cavity 110, disperses the release of stress, reduces the stress on the cooling collecting container 100, avoids the cracking and splashing phenomenon caused by the stress release of the organic material solid at the bottom of the collecting cavity, and prevents the cooling collecting container 100 from breaking.
[0057] In some embodiments, refer to Figure 5 and Figure 6 As shown, the ratio of the vertical height of the collecting component 200 to the vertical height of the collecting cavity 110 ranges from 1:2 to 1:5.
[0058] The height of the collector 200 should not be too low to ensure that the organic material gas can adhere to the surface of the collector 200 and condense into organic material solid. If the height of the collector 200 is too high, it will hinder the diffusion of the organic material gas. Ensure that the organic material gas can adhere evenly to the surface of the collector 200.
[0059] In some embodiments, refer to Figure 5 and Figure 6 As shown, the collector 200, which is provided with multiple curved portions 202, is configured as a wave-shaped plate structure, with the multiple curved portions 202 bending toward the front and back of the collector 200 respectively.
[0060] Reference Figure 5 As shown, a collector 200 with multiple curved portions 202 is vertically disposed at the bottom of the collection cavity 110, such that the front and back of the collector 200 face the two horizontally opposite inner walls of the collection cavity 110 respectively.
[0061] This allows the organic material solids to be uniformly condensed on the front and back of the collector 200.
[0062] Reference Figure 6 As shown, a collector 200 with multiple curved sections 202 is laid flat at the bottom of the collection chamber 110. The multiple curved sections 202 are bent toward the front and back of the collector 200 respectively, so that the front and back of the collector 200 face the vertical sides respectively, so that the organic material solid can condense on the front or back of the collector 200.
[0063] In some embodiments, the collecting member 200 releases the stress generated after material adhesion in a deformable manner, and the collecting member 200 is preferably a deformable component.
[0064] When organic solid material condenses on the surface of the collector 200, since the collector 200 is a component that can deform under stress, the stress released by the organic solid material causes the collector 200 to deform. The collector 200 transforms the stress released by the organic solid material into its own deformation, preventing the stress released by the organic solid material from being applied to the bottom of the collection cavity 110, thereby avoiding the organic solid material from breaking and splashing.
[0065] In some embodiments, the collecting element 200 releases the stress generated after the material adheres by deforming, and the cross-sectional thickness of the collecting element 200 is less than 10 mm.
[0066] The collector 200 has a smaller thickness, which reduces the elastic modulus of the collector 200 and ensures that the collector 200 can deform after the release of the solid stress of the organic material.
[0067] In some embodiments, the collecting component 200 is configured as a component made of a deformable material with a thickness of no more than 0.5 mm, such as a stainless steel strip.
[0068] In some embodiments, the collection element 200 is made of stainless steel or quartz glass.
[0069] The collector 200 is a stainless steel part made of stainless steel. After the stress of the organic material solidified on the surface of the collector 200 is released, the stainless steel part is easy to deform, so that the collector 200 can adapt to the structure of the solidified organic material.
[0070] The collector 200 is a quartz glass component made of quartz glass material, which has a high heat resistance and does not react with organic materials.
[0071] In some embodiments, refer to Figure 3 , Figure 4 and Figure 7 As shown, in the first, second, and fifth embodiments of the collection component 200, multiple collection components 200 are provided, and the multiple collection components 200 are arranged at intervals at the bottom of the collection cavity 110.
[0072] Reference Figure 3 and Figure 4As shown, multiple collection components 200 are spaced apart at the bottom of the collection chamber 110. Each collection component 200 divides the collection chamber 110 into multiple smaller areas. The solidified organic material is divided into multiple small solid areas by the collection components 200. The stress of each small solid area is much smaller than the overall stress of the organic material solid before separation. The stress of the organic material solid is released through the collection components 200. After its reaction force is greatly reduced, the organic material solid can be prevented from cracking and splashing, and the stress on the cooling collection container 100 is reduced.
[0073] Reference Figure 7 As shown, in the fifth embodiment of the collecting element 200, two collecting elements 200 are provided at intervals at the bottom of the collecting cavity 110.
[0074] Reference Figure 7 As shown, in the fifth embodiment of the collection component 200, each collection component 200 is provided with a plurality of collection slots 210 that extend vertically through the collection slots.
[0075] The collecting component 200 has a porous grid structure. The solidified organic material is divided into multiple small solid areas by the collecting component 200. The stress of each small solid area is much smaller than the overall stress of the organic material before separation. The stress of the organic material is released through the collecting component 200. After the reaction force is greatly reduced, the organic material can be prevented from cracking and splashing. At the same time, the stress on the cooling collection container 100 is reduced.
[0076] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
