Description

Technical Field

[0001] This utility model relates to the field of graphite material disk technology, and in particular to a device for a seven-layer graphite material disk. Background Technology

[0002] In the dehydroxylation process of products in industries such as semiconductors and photovoltaics, the single-batch capacity of the dehydroxylation furnace directly affects production costs and efficiency. Traditional dehydroxylation furnaces use graphite tray devices with a five-layer structure. With the expansion of production scale and the increasing demand for cost reduction, there is an urgent need for a device that can increase the single-batch loading capacity and improve production capacity by optimizing the tray loading design without changing the main structure of the dehydroxylation furnace. Against this background, an improved device technology with a seven-layer graphite tray has emerged. This device aims to provide a new solution for improving the production efficiency and economy of the dehydroxylation process by expanding the number of tray layers.

[0003] In the prior art, the graphite tray device for dehydroxylation furnaces usually adopts a mechanical structure with multiple layers of graphite plates and graphite columns stacked together. The technical principle is that the graphite columns support the upper and lower layers of graphite plates to form a multi-layer material loading platform. Each tray independently carries the material, and the stability of the stacked structure is maintained by the rigid support of the graphite columns. After the material is placed on each tray according to specifications, it enters the dehydroxylation furnace for processing as a whole. The mechanical connection of this structure is mostly a simple stacking type, and the inter-layer positioning mainly relies on the size matching of the graphite columns and graphite plates, without setting up complex limiting or adjustment components.

[0004] However, existing five-layer graphite tray devices have a limited single loading capacity, which makes it difficult for the dehydroxylation furnace to meet the growing production demand. Especially when multiple specifications of products are produced simultaneously, frequent loading and unloading operations increase energy consumption and labor costs. The improved seven-layer graphite tray device effectively solves this problem by increasing the number of layers to expand the loading space, significantly improving the single-batch capacity of the dehydroxylation furnace and reducing the production cost per unit product. Therefore, a seven-layer graphite tray device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device with a seven-layer graphite tray, which aims to improve the problems of limited single loading capacity and insufficient dehydroxylation furnace capacity of the existing five-layer graphite tray device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for a seven-layer graphite material tray includes a support plate, a plurality of graphite columns are fixedly connected to the top of the support plate, support blocks are slidably connected to the outer walls of the plurality of graphite columns, material support plates are fixedly connected to the upper surfaces of the plurality of support blocks, and an adjustment component is provided on one side of the plurality of support blocks.

[0008] The adjustment assembly includes multiple connecting shafts, one end of each connecting shaft is fixedly connected to the side wall of the support block, and a sliding shaft is slidably connected inside each connecting shaft. One end of each sliding shaft is fixedly connected to a locking shaft. Multiple slots are provided inside the graphite column, and the locking shaft engages with the slots. A spring is sleeved on the outer wall of the sliding shaft, one end of which is fixedly connected to the inner wall of the connecting shaft, and the other end is fixedly connected to the side wall of the locking shaft. Multiple protective components are provided on the side wall of the material support plate.

[0009] As a further description of the above technical solution:

[0010] Multiple protective components include a fixing plate and a fixing seat. One side of the fixing plate is fixedly connected to the side wall of the material support plate, and one side of the fixing seat is fixedly connected to the upper surface of the fixing plate.

[0011] As a further description of the above technical solution:

[0012] A pressing block is fixedly connected to one side of the fixed base, and symmetrical connecting columns are fixedly connected to one side of the fixed base.

[0013] As a further description of the above technical solution:

[0014] Each of the connecting columns has a sliding column slidably connected to its outer wall, and a spring is sleeved on the outer wall of each sliding column.

[0015] As a further description of the above technical solution:

[0016] One end of the spring is fixedly connected to the side wall of the connecting column, and the other end is fixedly connected to the side wall of the sliding column.

[0017] As a further description of the above technical solution:

[0018] A sleeve is fixedly connected to the outer wall of the extrusion block, and a sliding block is slidably connected inside the sleeve.

[0019] As a further description of the above technical solution:

[0020] A protective ring is fixedly connected to one side of the sliding block, and the outer wall of the protective ring is fixedly connected to the side wall of the sliding column.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by adding two layers of graphite columns to the original five-layer structure, the single loading capacity is significantly increased. Tests have verified that this has no adverse effect on product quality and can effectively improve the single-batch capacity of the dehydroxylation furnace. By pulling the sliding shaft, the locking shaft is disengaged from the locking groove. Then, by pulling the material support plate, the spacing can be quickly adjusted, solving the problem that the fixed layer spacing of the existing device is difficult to adapt to different specifications of products and improving the production changeover efficiency of dehydroxylation production of multi-specification products.

[0023] 2. In this utility model, the sliding block slides inside the sleeve, thereby squeezing the second spring. The elastic deformation of the second spring quickly absorbs and buffers the impact force, thus achieving the effect of elastic protection for the quartz tube. This solves the problem that quartz tubes are easily damaged by collisions and shaking during loading and transportation, and improves the yield rate and loading and unloading efficiency of quartz tube dehydroxylation production.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a seven-layer graphite material tray device, including a support plate 1. Multiple graphite columns 2 are fixedly connected to the top of the support plate 1. The distribution and arrangement of the graphite columns 2 are reasonably installed according to actual needs to ensure that they can support multiple material trays 4 and provide support for the stability of the device. Support blocks 3 are slidably connected to the outer walls of the multiple graphite columns 2. The design of the support blocks 3 has a certain degree of sliding and can be displaced accordingly with the movement of the adjustment components, thereby adjusting the height and position of the material trays 4 to meet the needs of multi-layer stacking. Material trays 4 are fixedly connected to the upper surfaces of the multiple support blocks 3. Through the connection with the support blocks 3, the material trays 4 can maintain a stable suspended state under the support of each graphite column 2. Adjustment components are provided on one side of the multiple support blocks 3 to adjust the vertical height and interlayer distance of the material trays 4 according to the needs.

[0033] The adjustment assembly includes multiple connecting shafts 5, one end of which is fixedly connected to the side wall of the support block 3. Each connecting shaft 5 has a sliding shaft 6 slidably connected inside it. One end of each sliding shaft 6 is fixedly connected to a locking shaft 7. The locking shaft 7 is designed to precisely engage with multiple slots 8 formed on the inner wall of the graphite column 2. The locking shaft 7 engages with the slots 8. This engagement structure ensures that the locking shaft 7 is precisely fixed in the predetermined position during adjustment, preventing displacement of the material support plate 4 due to external interference. A spring 9 is sleeved on the outer wall of the sliding shaft 6. The spring 9 provides elastic support during adjustment, ensuring free rebound. One end of the spring 9 is fixedly connected to the inner wall of the connecting shaft 5, and the other end is fixedly connected to the side wall of the locking shaft 7. Multiple protective components are provided on the side wall of the material support plate 4. These protective components are mainly used to protect the quartz tube and other materials from external impacts and wear.

[0034] Reference Figure 4 and Figure 5Multiple protective components include a fixing plate 10 and a fixing seat 11. One side of the fixing plate 10 is fixedly connected to the side wall of the material support plate 4 to ensure the stability of the fixing plate 10 on the material support plate 4. One side of the fixing seat 11 is fixedly connected to the upper surface of the fixing plate 10. A pressing block 12 is fixedly connected to one side of the fixing seat 11. A pair of vertically symmetrical connecting columns 13 are fixedly connected to one side of the fixing seat 11. Sliding columns 14 are slidably connected to the outer walls of multiple connecting columns 13. Springs 15 are sleeved on the outer walls of the sliding columns 14 to provide support for the sliding columns 14. Force is used to ensure that the protective component can operate stably throughout the adjustment process. One end of the spring 15 is fixedly connected to the side wall of the connecting column 13, and the other end is fixedly connected to the side wall of the sliding column 14. The outer wall of the pressing block 12 is fixedly connected to the sleeve 16, and the inside of the sleeve 16 is slidably connected to the sliding block 17. The sliding block 17 can slide freely inside the sleeve 16, thereby increasing the flexibility of the protective component and further ensuring the stability of the protective component. One side of the sliding block 17 is fixedly connected to the protective ring 18, and the outer wall of the protective ring 18 is fixedly connected to the side wall of the sliding column 14.

[0035] Working Principle: The seven-layer graphite tray device is based on the original five-layer graphite tray structure. It is modified and expanded using graphite pillars 2. After loading materials such as quartz rods and tubes into each layer of the graphite tray, the upper platform is built using graphite pillars 2 and support plates 4. This process is repeated until seven layers are formed, creating a complete loading structure. During installation, by pulling the sliding shaft 6, the pulling force causes the locking shaft 7 to contract inwards towards the connecting shaft 5, thereby compressing spring 9 and causing it to elastically deform, storing elastic potential energy. Then, by releasing the pulling force, spring 9 elastically recovers its shape. The force pushes the locking shaft 7 into the locking groove 8 to achieve locking, thereby restricting its movement and ensuring the stability of its transfer. At the same time, it allows the user to easily adjust the distance between multiple material support plates 4, improving flexibility. During loading, the protective ring 18 prevents the quartz tube from colliding with the device body. The protective ring 18 drives the sliding block 17 to slide inside the sleeve 16, and at the same time drives the sliding column 14 to slide on the outer wall of the connecting column 13, thereby squeezing the second spring 15. The elastic restoring force and elastic deformation capacity of the second spring 15 absorb and buffer the impact force, providing elastic protection for the quartz tube.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
