Description

Technical Field

[0001] This utility model belongs to the technical field of quartz boats for annealing, and specifically relates to quartz boats for annealing. Background Technology

[0002] In the field of materials heat treatment, annealing is a crucial step in improving material properties. Quartz boats, as commonly used annealing support tools, are widely used due to their high temperature resistance and strong chemical stability. However, existing annealing quartz boats have several shortcomings in practical use. On the one hand, traditional quartz boats offer a limited method for fixing annealed samples, making them prone to slipping and tipping, affecting the uniformity of the annealing effect. On the other hand, during annealing, the gas needs to be in full contact with the sample to achieve a good annealing reaction, but the structure of existing quartz boats is not conducive to gas flow and diffusion, resulting in low annealing efficiency. Furthermore, existing quartz boats can only hold products of a single specification. Quartz boats also suffer from inconvenient handling and operation, and difficulty in removing products. Utility Model Content

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quartz boat for annealing, including a support plate and several sets of clamping blocks. Side plates are connected to both sides of the support plate, and end plates are connected to both ends of the support plate. Each set of clamping blocks includes several bottom clamping blocks and several side clamping blocks. The bottom clamping blocks are located on the support plate and are fixedly connected to the support plate. The side clamping blocks are located on the side plates and are fixedly connected to the corresponding side plates. The bottom clamping blocks and side clamping blocks in each set of clamping blocks are located in the same vertical plane. Several support plates are connected to the lower end of the support plate. The support plates, support plate, bottom clamping blocks, side clamping blocks, side plates and end plates are all made of quartz.

[0004] As a preferred embodiment of the above technical solution, the tray and side plate are provided with a number of ventilation holes, and the end plate is provided with a hand hole.

[0005] As a preferred embodiment of the above technical solution, each set of clamping blocks includes at least two bottom clamping blocks, and the middle of the support plate is provided with an elongated through hole.

[0006] As a preferred embodiment of the above technical solution, an eccentric shaft is provided in the elongated through hole, and the two ends of the eccentric shaft are respectively connected to a rotating support plate through a rotating shaft. The support plate is provided with a round hole for the rotating shaft to pass through, and a swing rod is fixedly connected after the rotating shaft passes through the round hole.

[0007] As a preferred embodiment of the above technical solution, the bottom clamping block and the side clamping block are respectively cylindrical, with the end face of the bottom clamping block smoothly transitioning to the circumferential surface, and the end face of the side clamping block smoothly transitioning to the circumferential surface.

[0008] The beneficial effects of this invention are as follows: The quartz boat for annealing can be used to place workpieces of various shapes; the clamping block structure can firmly fix the sample from the bottom and sides, preventing the sample from sliding or tipping over in a high-temperature and vibrating environment, ensuring the uniformity of annealing; the vent design of the support plate and side plates optimizes the gas flow path, promotes full contact between the gas and the sample, and significantly improves the annealing reaction efficiency; the hand hole on the end plate facilitates safe handling by operators, and the eccentric shaft and swing arm structure facilitates sample unloading. These designs effectively solve the shortcomings of traditional quartz boats and meet the stringent requirements of high-end material manufacturing for annealing processes.

[0014] like Figure 1-2As shown, the quartz boat for annealing includes a support plate 1 and several sets of clamping blocks. Side plates 2 are connected to both sides of the support plate 1, and end plates 3 are connected to both ends of the support plate 1. Each set of clamping blocks includes several bottom clamping blocks 4 and several side clamping blocks 5. The bottom clamping blocks 4 are located on the support plate 1 and fixedly connected to it, while the side clamping blocks 5 are located on the side plates 2 and fixedly connected to the corresponding side plates 2. The bottom clamping blocks 4 and side clamping blocks 5 in each set of clamping blocks are located in the same vertical plane. Several support plates 6 are connected to the lower end of the support plate 1. The support plates 6, support plate 1, bottom clamping blocks 4, side clamping blocks 5, side plates 2, and end plates 3 are all made of quartz. The bottom clamping blocks 4 and side clamping blocks 5 cooperate to clamp the workpiece between adjacent sets of clamping blocks. Workpieces of different shapes, such as square and round, can be placed inside the quartz boat.

[0015] Furthermore, the support plate 1 and the side plate 2 are respectively provided with a plurality of ventilation holes 7, and the end plate 3 is provided with a hand hole 8. The ventilation holes 7 improve the airflow effect inside the quartz boat and prevent the local temperature inside the quartz boat from becoming too high. The hand hole 8 makes it convenient to hold the quartz boat and move it.

[0016] Furthermore, each set of clamping blocks includes at least two bottom clamping blocks 4, and the center of the support plate 1 is provided with an elongated through hole 9. The lower end of the circular workpiece can extend into the elongated through hole 9, reducing the height of the workpiece and enabling the quartz boat to accommodate circular workpieces of a larger size range.

[0017] Furthermore, an eccentric shaft 10 is provided in the elongated through hole 9. The two ends of the eccentric shaft 10 are rotatably connected to the support plate 1 via a rotating shaft 11. The support plate 1 has a circular hole for the rotating shaft 11 to pass through. After the rotating shaft 11 passes through the circular hole, a rocker arm 12 is fixedly connected to it. By rotating the rotating shaft 11 through the rocker arm 12, the eccentric shaft 10 is driven to rotate. During the rotation of the eccentric shaft 10, it extends out of the elongated through hole 9, pushing the workpiece inside the quartz boat to a certain height, making it convenient to grab smaller workpieces from the quartz boat.

[0018] Furthermore, the bottom clamping block 4 and the side clamping block 5 are respectively cylindrical, with the end face of the bottom clamping block 4 smoothly transitioning to the circumferential surface, and the end face of the side clamping block 5 smoothly transitioning to the circumferential surface. The clamping block surfaces are smooth and are welded to the support plate 1 and the side plate 2.

The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0020] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
