Description

Technical Field

[0001] The utility model relates to the technical field of purification of organic materials, and particularly relates to a sublimation boat. Background Art

[0002] For the purification of high - requirement organic small - molecule materials, a sublimation device is usually used for sublimation purification of the materials. The specific method is as follows: in a sublimation device with multiple temperature zones, the material to be purified is placed in a sublimation boat, and the purified material is vaporized by reducing pressure and heating. Then, the collection boat in the sublimation device cools and solidifies the material through low temperature to achieve the purpose of sublimation purification.

[0003] In order to make the thickness of the material to be purified in the sublimation boat smaller, and to avoid the residue of the material after sublimation covering the bottom material so that the bottom material is always heated but cannot sublimate, and finally resulting in the deterioration, carbonization and decomposition of the bottom material. In the prior art, the sublimation boat includes a boat body and a material tray for horizontally accommodating the material to be sublimated. A plurality of pairs of strip - shaped protrusions are arranged on the inner wall of the boat body, and the strip - shaped protrusions extend along the direction in which the material tray is inserted into the boat body. Slots are formed on the material tray, and the strip - shaped protrusions can be inserted into the slots so that two strip - shaped protrusions arranged in pairs support the material tray.

[0004] In order to avoid contaminating the material by the sublimation boat, the sublimation boat is often made of quartz. Since the forming ability of quartz is poor, it is difficult to form the strip - shaped protrusions inside the sublimation boat, and the processing cost is high. At the same time, a dead angle is formed at the connection between the strip - shaped protrusions and the inner wall of the boat body, and the dead angle is located inside the boat body, making it difficult to clean the inside of the boat body. Therefore, when sublimating different materials in the sublimation boat, cross - contamination is likely to occur. In addition, when installing the material tray, the slots need to be aligned with the strip - shaped protrusions, resulting in low installation efficiency of the material tray and low working efficiency. Summary of the Utility Model

[0036] This embodiment provides a sublimation boat for purifying materials by sublimation, but not limited thereto, to reduce the cost of the sublimation boat and the difficulty of cleaning.

[0037] As Figures 1 - 3 shown, the sublimation boat provided in this embodiment includes a cylindrical boat 1 and a material carrying assembly 2. One end of the cylindrical boat 1 is a closed end, and the other end is an open end. The cylindrical boat 1 is cylindrical. The material carrying assembly 2 includes at least one material tray 21. The material tray 21 includes a bottom wall 212 and side walls 211. Both sides in the width direction of the bottom wall 212 are connected with side walls 211. The outer wall surface of the side walls 211 is an arc structure, and the curvature of the arc structure is the same as the curvature of the inner wall of the cylindrical boat 1, so that the inner wall of the cylindrical boat 1 supports the outer wall surface of the side walls 211.

[0038] In this embodiment, by designing the outer wall surface of the side wall 211 into an arc structure, the arc structure cooperates with the cylindrical boat 1, so that the inner wall of the boat 1 supports the side wall 211, and then the material tray 21 is fixed in the boat 1. The inner wall of the boat 1 is smooth and does not require additional processing of strip protrusions, reducing the processing difficulty of the boat 1 and the processing cost of the boat 1 is low. In addition, the inner wall of the boat 1 is smooth and easy to clean, and cross-contamination will not occur when sublimating different types of materials. Since the boat 1 is cylindrical, when the boat 1 is placed horizontally (i.e., the axis of the boat 1 is located on the horizontal plane), as long as the material tray 21 is inserted into the boat 1 along the axis of the boat 1, the inner wall of the boat 1 can support the side wall 211. Therefore, when installing the material tray 21, it is not necessary to repeatedly adjust the position of the material tray 21 for alignment, improving the installation efficiency and working efficiency.

[0039] As Figure 4 shown, optionally, the number of the material trays 21 is at least two, and at least two material trays 21 are stacked in sequence along the radial direction of the boat 1. In this way, materials can be laid flat on all the material trays 21, improving the load capacity of the sublimation boat and the working efficiency. During use, the number of loading trays to be used can be judged according to the situation, and the operation is flexible. In this embodiment, four material trays 21 are provided, but the number of the material trays 21 is not limited to this, and can be more than four or less than four.

[0040] The widths of the bottom walls 212 of at least two material trays 21 stacked in sequence along the radial direction of the boat 1 from bottom to top gradually increase, so that the side wall 211 abuts against the inner wall of the boat 1, and at the same time, the load capacity of the material is increased. It can be understood that in this embodiment, up and down refer to the up and down of the sublimation boat in the use state, such as Figure 4 shown in the up and down.

[0041] Optionally, the outer edge and / or inner edge of the end of the side wall 211 away from the bottom wall 212 is a rounded corner, so as to prevent the side wall 211 from scratching the operator.

[0042] In two adjacent material trays 21, the distance between the upper surface of the bottom wall 212 of the lower material tray 21 and the bottom wall 212 of the upper material tray 21 is not less than 2 cm, so as to facilitate the sublimation of materials between two adjacent material trays 21. In this embodiment, the side wall 211 also functions to keep the bottom walls 212 between two adjacent material trays 21 at a preset distance.

[0043] Optionally, during use, the material is laid flat on the upper surface of the bottom wall 212, and the thickness of the laid material is not greater than 5 mm, so as to avoid the residue after sublimation of the material covering the material and the deterioration, carbonization and decomposition of the bottom material.

[0044] As Figure 4 and Figure 5As shown, optionally, the material carrying component 2 further includes a bottom material tray 22. The cross-section of the bottom material tray 22 is arc-shaped, and the curvature of the arc is the same as that of the inner wall of the cylindrical boat 1, so that the outer surface of the bottom material tray 22 fits against the inner wall of the cylindrical boat 1. Along the radial direction of the cylindrical boat 1, the material trays 21 are stacked on the bottom material tray 22. It can be understood that in this embodiment, the terms "inner" and "outer" refer to the inner and outer of the cylindrical boat 1, or the outer and inner of the space enclosed by the material tray 21 or the bottom material tray 22.

[0045] Specifically, the bottom material tray 22 is located at the lowermost side of the material carrying component 2, and a plurality of material trays 21 are sequentially stacked on the upper side of the bottom material tray 22 along the radial direction of the cylindrical boat 1.

[0046] The large contact area between the bottom material tray 22 and the cylindrical boat 1 can further improve the stability of the material carrying component 2. In addition, since the cylindrical boat 1 is cylindrical and the cross-section of the bottom material tray 22 is arc-shaped and the curvature of the arc is the same as that of the inner wall of the cylindrical boat 1, the bottom material tray 22 can fit against any position in the circumferential direction of the cylindrical boat 1, and the installation of the bottom material tray 22 is convenient.

[0047] The surfaces of the material tray 21 and the bottom material tray 22 that are in contact with each other are both flat surfaces, thereby improving the stability of the material tray 21. Optionally, the surfaces of two adjacent material trays 21 that are in contact with each other are also flat surfaces, thereby improving the stability of the material tray 21.

[0048] When using the sublimation boat, the material is placed on the upper surface of the bottom material tray 22, and the distance between the lowest point of the upper surface of the bottom material tray 22 and the bottom wall 212 is not less than 2 cm. This facilitates the sublimation of the material on the bottom material tray 22 between the material tray 21 and the bottom material tray 22.

[0049] Optionally, the maximum thickness of the material on the bottom material tray 22 is not greater than 5 mm, so as to avoid the residue after the sublimation of the material covering the material and the deterioration, carbonization and decomposition of the bottom material.

[0050] As Figure 4 and Figure 6 shown, exemplarily, the material carrying component 2 may further include a top material tray 23. The top material tray 23 is a flat plate structure, and along the radial direction of the cylindrical boat 1, the top material tray 23 is stacked on the material tray 21. The top material tray 23 is located at the uppermost side of the material carrying component 2 and is supported by the material tray 21 below it and fixed in the cylindrical boat 1. The structure of the top material tray 23 is simple.

[0051] The distance between the upper surface of the bottom wall 212 of the material tray 21 located at the uppermost side and the top material tray 23 is not less than 2 cm, so as to facilitate the sublimation of the material on the material tray 21 between the material tray 21 and the top material tray 23.

[0052] The height of the material carrying component 2 is not higher than the inner radius of the cylindrical boat 1 to avoid excessive weight of the sublimation boat and bring adverse effects to the sublimation equipment.

[0053] Optionally, the length of the material carrying component 2 is less than the axial dimension of the cylindrical boat 1, so as to reserve an empty position at the open end of the cylindrical boat 1, and other related devices such as a filter can be added at the reserved empty position.

[0054] Optionally, both the cylindrical boat 1 and the material carrying component 2 can be made of quartz glass.

[0055] In this embodiment, one end of the cylindrical boat 1 is sealed and the other side is completely open, which is convenient for cleaning and provides convenience for the insertion and removal of the material carrying component 2. The structure of the sublimation boat is simple and there is no complex process in the manufacturing process, so the manufacturing cost is low. The side wall 211 of the material tray 21 is closely attached to the inner wall of the cylindrical boat 1, so as to support the material tray 21 and play a role in supporting and fixing the material tray 21. At the same time, a certain distance can be maintained between the bottom walls 212 of two adjacent material trays 21 or between the bottom wall 212 of the material tray 21 and the top material tray 23.

[0056] In addition, during use, the number of material trays 21 to be used and whether the bottom material tray 22 and the top material tray 23 need to be used can be judged according to the amount of the material, and the operation is flexible and convenient.

[0057] The thickness of each layer of material in the material carrying component 2 is small, which avoids residue covering the material, reduces the heating time of the material, and reduces the possibility of the material deteriorating due to long-term heating.

[0058] Compared with the sublimation boat without the material carrying component 2, the single charging amount of the sublimation boat in this embodiment can be tripled. Since the material is thinly paved in layers on the material carrying component 2, the sublimation time is reduced, and more materials can be sublimated in a shorter time, increasing the sublimation efficiency.

[0059] Although the present invention has been described in detail above with general descriptions, specific embodiments and experiments, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
