Description

Technical Field

[0001] This utility model belongs to the field of crystal furnace technology, and more specifically, it relates to a crystal synthesis furnace for producing crystals. Background Technology

[0002] In modern industry, crystal materials, due to their unique physical and chemical properties, have extremely wide and crucial applications in many industries such as electronics, optics, and semiconductors. Currently, crystal production mainly relies on various crystal synthesis furnaces, commonly including [Czochralski crystal synthesis furnaces, hydrothermal crystal synthesis furnaces, and crucible lowering crystal synthesis furnaces]. While these furnaces can meet the needs of crystal growth to a certain extent, they also have many problems. Furthermore, some drawbacks have been found in current crystal synthesis furnaces:

[0003] Firstly, the insulation layer inside the current crystal synthesis furnace is exposed to high temperatures for a long time, and its insulation performance will gradually deteriorate with the increase of usage time, so it needs to be replaced to ensure that the furnace body can maintain stable insulation performance. Furthermore, the common adhesive type is not easy to disassemble, thus increasing the difficulty of operation.

[0004] Secondly, the furnace body and furnace cover of most crystal synthesis furnaces are locked together with bolts. This method is time-consuming and inconvenient to operate when disassembling and feeding materials, requiring the use of tools to disassemble, thus increasing the complexity of feeding materials.

The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0040] Example 1:

[0041] Please refer to Figures 1 to 6 :

[0042] This utility model provides a crystal synthesis furnace for producing crystals, including an outer furnace body 1 and a heat insulation structure 3;

[0043] The outer furnace body 1 has a furnace cavity 101 inside. A support 102 is located at the bottom of the furnace cavity 101, and an inner furnace body 103 is located at the top of the support 102. An inner furnace cover 1031 is sealed and installed on the top of the inner furnace body 103. A fixing ring 301 is fixedly connected to the top of the outer furnace body 1. A through hole 3011 is formed on the fixing ring 301, and an assembly groove 3012 is formed at the through hole 3011. A first heat-insulating arc plate 302 is provided on the outer side of the inner furnace body 103. One end of the first heat-insulating arc plate 302 has a butt groove 3021, and the other end has a first insertion groove 3022. A second heat-insulating arc plate 303 is provided on one side opposite to the first heat-insulating arc plate 302. A mating arc block 3031 is fixedly connected to one end of the second heat-insulating arc plate 303. A pressing chamber 3032 is provided inside the mating arc block 3031. A movable sliding hole 3033 is located at the top of the mating arc block 3031. A spring 3034 is provided inside the pressing chamber 3032. A fixed pressure post 3035 is provided at the top of the spring 3034. An assembly stud 3036 is fixedly connected to the top of the fixed pressure post 3035. The assembly stud 3036 extends through the movable sliding hole 3033 and the through hole 3011 to the assembly groove 3012. A nut 305 is engaged at one end of the top of the first heat insulation arc plate 3022, and a second insertion groove 3037 is provided at the other end of the second heat insulation arc plate 303. A sealing block 304 is inserted into the first insertion groove 3022 and the second insertion groove 3037. The sealing block 304 is removed from the mounting stud 3036 by rotating the nut 305, and then the mounting stud 3036 is pressed down to move it downward and disengage it from the through hole 3011. Then the sealing block 304 is pulled out, and the first heat insulation arc plate 302 and the second heat insulation arc plate 303 can be separated for easy removal from the furnace cavity 101. During installation, only the first heat insulation arc plate 302 and the second heat insulation arc plate 303 need to be removed. 303 is placed into the furnace cavity 101 one after another. Then, the sealing plug 304 is inserted into the first insertion slot 3022 and the second insertion slot 3037 to assemble them. Then, it is attached to the furnace cavity 101. Then, the mounting stud 3036 is aligned with the through hole 3011. When the mounting stud 3036 moves down, it compresses the spring 3034 through the fixed pressure column 3035, so that the spring 3034 becomes elastic. Under the reaction force of the spring 3034, it pushes the fixed pressure column 3035 to move. The fixed pressure column 3035 drives the mounting stud 3036 to reset and pass through the through hole 3011. Then, the nut 305 is screwed on to complete the installation.

[0044] Furthermore, the top of the outer furnace body 1 is provided with an outer furnace cover 203, and a locking structure 2 is provided between the outer furnace body 1 and the outer furnace cover 203. The locking structure 2 includes an extension protrusion 201, a fixed hinge 2011 and a pin hole 2012. The extension protrusion 201 is fixedly connected to the rear side of the top of the outer furnace body 1, and the fixed hinge 2011 is fixedly connected to the top of the extension protrusion 201. The pin hole 2012 is provided on the fixed hinge 2011. The fixed hinge 2011 and the pin hole 2012 are used for hinged connection with the outer furnace cover 203.

[0045] Furthermore, a connecting lock frame 202 is fixedly connected to the top front side of the outer furnace body 1. A U-shaped groove 2021 is provided on the connecting lock frame 202, and a hinge groove 2022 is provided on the connecting lock frame 202. A flip hinge rod 2024 is hinged in the hinge groove 2022 through a first shaft pin 2023. The U-shaped groove 2021 is used to connect the card plate 2042 to move laterally, and at the same time, it lifts up and flips the flip hinge rod 2024. The flip hinge rod 2024 is used to limit the connection of the card plate 2042.

[0046] Furthermore, a hinge lug 2031 is fixedly connected to one rear end of the outer furnace cover 203. The hinge lug 2031 is hinged to the fixed hinge frame 2011 through the second shaft pin 2032, so as to facilitate the outer furnace cover 203 to be flipped in conjunction with the fixed hinge frame 2011.

[0047] Furthermore, a docking bend frame 2033 is fixedly connected to the front end of the outer furnace cover 203. The docking bend frame 2033 is provided with a movable shaft hole 2034. The docking bend frame 2033 is used to lock the outer furnace cover 203 to the outer furnace body 1 with the connecting lock frame 202. The movable shaft hole 2034 is used for the movable shaft 204 to move and rotate.

[0048] Furthermore, a movable shaft 204 is movably installed inside the movable shaft hole 2034. One end of the movable shaft 204 is fixedly connected to a connecting handle 2041, and the other end of the movable shaft 204 is fixedly connected to a connecting plate 2042. The connecting handle 2041 is used for the rotation and pushing of the movable shaft 204, and the connecting plate 2042 is used for the limiting after locking.

[0049] Example 2:

[0050] Based on Embodiment 1, the nut 305 is rotated to remove it from the mounting stud 3036, and then the mounting stud 3036 is pressed down to move it downwards and disengage it from the through hole 3011. Then, the sealing insert 304 is pulled out, allowing the first heat-insulating arc plate 302 and the second heat-insulating arc plate 303 to be disassembled and easily removed from the furnace cavity 101. This effectively shortens replacement time and reduces overall maintenance costs. Through the cooperation of the fixed hinge 2011, the hinge lug 2031, and the second shaft pin 2032, the outer furnace cover 203 is flipped and sealed. The top of the outer furnace body 1 is then rotated. The connecting handle 2041 is rotated so that the connecting plate 2042 is rotated to a horizontal position through the movable shaft 204. Then, the connecting handle 2041 is pushed to make the connecting plate 2042 pass through the U-shaped groove 2021 and lift the flipping hinge 2024. Under the principle of weight imbalance, the connecting plate 2042 automatically returns to a vertical position. Then, the flipping hinge 2024 is flipped down to lock it. It is simple and convenient, which greatly shortens the assembly and disassembly time of the synthesis furnace and the furnace cover, reduces the complexity of feeding, and effectively improves the overall production operation efficiency.
