Description

Technical Field

[0001] This utility model relates to the field of perovskite material processing technology, specifically to a perovskite material processing and placement structure. Background Technology

[0002] A vacuum freeze dryer is a device used for freeze-drying materials. It utilizes the principle of sublimation, converting moisture in materials directly from a solid to a gaseous state under extremely low temperatures and vacuum conditions, thus preserving the moisture content. Vacuum freeze dryers typically feature low temperature, vacuum, and rapid freezing. The main reason for storing perovskite materials in a vacuum freeze dryer is to maintain their structure and stability. Perovskite materials are highly chemically active compounds, easily affected by environmental factors and changes in their own structure, leading to alterations in their properties. The vacuum freeze dryer can process perovskite materials under low temperature, vacuum, and rapid freezing conditions, effectively inhibiting chemical reactions and moisture migration, thereby maintaining the material's structure and stability.

[0003] When perovskite materials are processed using a vacuum freeze dryer, clamping and positioning are necessary during placement to ensure accurate placement and maintain the material's original shape. Furthermore, the effectiveness of the vacuum freeze-drying process must be guaranteed. This affects the performance and stability of the perovskite material; therefore, we propose a perovskite material processing and placement structure. Utility Model Content

[0004] The purpose of this invention is to provide a perovskite material processing and placement structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a perovskite material processing and placement structure, including a vacuum freeze dryer, wherein the inner cavity of the vacuum freeze dryer is symmetrically provided with pulling structures, and a concave plate is fixedly connected between the inner sidewalls of two of the pulling structures. The number of concave plates is three, and they are arranged vertically in sequence. A first perforated plate is fixedly connected to the lower surface of the concave plate, and a baffle is fitted with the upper surface of the concave plate with a clearance fit. An insert plate is symmetrically fixedly connected to the sidewall of the baffle, and the sidewall of the insert plate is fitted with the inner cavity of the concave plate with a clearance fit.

[0006] Preferably, the pulling structure includes an inner plate, and there are two inner plates arranged symmetrically. The side wall of the inner plate is fixedly connected to the inner cavity of the vacuum freeze dryer. A semi-circular rod is fixedly connected to the other side of the inner plate. A side plate is sleeved on the outer wall of the semi-circular rod. One side of the side plate is clearance-fitted with the side wall of the inner plate. A concave plate is fixedly connected to the other side of the side plate.

[0007] Preferably, a rubber strip is glued to the lower surface corner of the baffle, and the sidewall of the rubber strip is in contact with the upper surface of the concave plate.

[0008] Preferably, the number of semicircular rods on one side is three, and they are arranged vertically in sequence.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When processing perovskite materials using a vacuum freeze dryer, the perovskite material is placed inside a concave plate with grooves, and a sliding baffle is set on top for snap-fit ​​positioning. Through the snap-fit ​​positioning of the sliding baffle, the weight of the baffle itself presses down, and the insert plate slides inside the concave plate, so that the baffle clamps and positions the perovskite material. The operation is simple and convenient. A first perforated plate is opened at the bottom of the concave plate, and the surface of the first perforated plate is covered with through holes to facilitate maintaining vacuum and low temperature conditions. This allows the perovskite material to better contact with vacuum and low temperature conditions during the freeze-drying process, thereby improving the drying efficiency.

[0017] Please see Figure 1-5This utility model provides a perovskite material freeze-drying and preservation device, including a vacuum freeze dryer 1. The inner cavity of the vacuum freeze dryer 1 is symmetrically provided with a pulling structure 2. A concave plate 3 is fixedly connected between the inner sidewalls of two pulling structures 2.

The sidewall of the insert plate 7 is fitted with the inner cavity of the concave plate 3 with a clearance fit.

[0018] The vacuum freeze dryer 1, model LGJ-10FD, is existing technology in this field. When storing perovskite material in the vacuum freeze dryer 1, the vacuum freeze dryer 1 is opened, the concave plate 3 is pulled out by the pull structure 2, and the baffle 5 is pulled upward. Since the baffle 5 is layered, it is fixed by the insert plate 7. By pulling upward, the interior of the concave plate 3 is exposed, and the perovskite material is placed inside the concave plate 3. The concave plate 3 is provided with a first perforated plate 4, which is used to place the perovskite material. After placement, the baffle 5 is released, and the weight of the baffle 5 presses down, causing the insert plate 7 to... The material will slide inside the concave plate 3, allowing the baffle 5 to clamp and position the perovskite material. Then, it will be pushed to place the concave plate 3 inside the vacuum freeze dryer 1. The vacuum freeze dryer 1 will be turned on. Since the surface of the first baffle plate 4 is provided with through holes, it is convenient to maintain vacuum and low temperature conditions. Through the fixed limit of the baffle 5 and the concave plate 3, the perovskite material can be clamped. At the same time, the surfaces of the first baffle plate 4 and the second baffle plate 6 are provided with through holes. During the clamping process, it is ensured that the perovskite material can better contact the vacuum and low temperature conditions during the freeze drying process, thereby improving the drying efficiency.

The side wall of the inner plate 21 is fixedly connected to the inner cavity of the vacuum freeze dryer 1. The other side of the inner plate 21 is fixedly connected to a semi-circular rod 22. A side plate 23 is sleeved on the outer wall of the semi-circular rod 22. One side of the side plate 23 is clearance-fitted with the side wall of the inner plate 21.

The side plate 23 can be sleeved with the semi-circular rod 22. The side plate 23 slides against the outer wall of the semi-circular rod 22, which increases the pulling function of the concave plate 3 and facilitates the placement of materials in the concave plate 3 for processing.

[0020] A rubber strip 8 is glued to the lower surface corner of the baffle 5. The side wall of the rubber strip 8 is attached to the upper surface of the concave plate 3. The rubber strip 8 can be attached to the concave plate 3 to reduce wear during fastening.

[0021] There are three semi-circular rods 22 on each side, arranged vertically in sequence. The installation of the side plate 23 can be made more stable by setting multiple semi-circular rods 22.
