Description

Technical Field

[0001] The utility model relates to the technical field of graphite, and more specifically, to a graphite mold for a crystallizer. Background Art

[0002] A crystallizer is a container or mold used to heat a liquid material (such as a metal or semiconductor material) above its melting point under high-temperature conditions for smelting, crystal growth, or other high-temperature processing processes. A graphite mold is a mold made of graphite material, which has excellent high-temperature heat resistance, thermal conductivity, and chemical stability, and is commonly used in high-temperature processing or forming processes.

[0003] Although the existing graphite mold of the crystallizer has a cooling structure, during the cooling process, due to the high temperature inside, a large amount of water vapor is generated. These water vapors cannot be discharged and thus diffuse inside the mold, resulting in uneven heating of the internal transistors, thereby affecting the cooling and crystallization work.

[0004] Therefore, it is necessary to design a graphite mold for a crystallizer. Summary of the Utility Model

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a graphite mold for a crystallizer, which can cool the crystallization tube comprehensively and evenly and absorb the water vapor inside the mold, thereby reducing the escape of water vapor.

A cooling component is installed on the sleeve. The top end of the sleeve is covered with a sealing cover, and a sealing ring is installed at the joint of the sealing cover and the sleeve. The inner upper surface of the furnace body is provided with a graphite mold main body. A crystallization tube is inserted into the graphite mold main body and extends into the sleeve. Partition plates are fixedly connected to both the upper and lower ends inside the sleeve, and the two partition plates divide the sleeve into a flow-dividing chamber and a flow-collecting chamber respectively.

[0027] Embodiment 1:

[0028] Please refer to Figures 1-4, a graphite mold for a crystallizer, comprising a furnace body 1. A sleeve 4 is inserted above the furnace body 1. The sleeve 4 and the furnace body 1 are fixedly connected through a mounting ring 3. A cooling component 2 is installed on the sleeve 4. A sealing cover 6 is provided at the top end of the sleeve 4. A sealing ring 5 is installed at the joint where the sealing cover 6 fits with the sleeve 4. The upper surface inside the furnace body 1 is provided with a graphite mold body 12. A crystallization tube 9 is inserted into the graphite mold body 12 and extends into the sleeve 4. Partition plates 7 are fixedly connected to both the upper and lower ends inside the sleeve 4, and the two partition plates 7 divide the sleeve 4 into a flow - dividing chamber 8 and a flow - converging chamber 10 respectively. In this solution, by setting the cooling component 2, the crystallization tube 9 is cooled comprehensively and evenly by using the characteristic of cyclic cooling of the structure, which is conducive to the formation of crystals. In cooperation with the annular silica gel plate 25 and the moisture - absorbing coating inside the cooling component 2, the water vapor inside the mold is absorbed, thereby reducing the escape of water vapor and improving the moisture absorption of the mold. Through the setting of the graphite sleeve 11, the graphite mold body 12, and the tapered copper protective sleeve 13, the slag and oxides mixed on the surface of the copper alloy solution are effectively prevented from entering the graphite mold, ensuring the quality of the crystallizer.

[0029] According to Figure 2 , the cooling component 2 includes a drainage pipe 21. The drainage pipe 21 is inserted through the outer wall of the flow - converging chamber 10. One end of the drainage pipe 21 is installed with a drainage hose 22. The top end of the drainage hose 22 is installed with a cooling water jacket 26, and the cooling water jacket 26 is adapted to the crystallization tube 9 and is snap - connected to the inner wall of the sleeve 4. By setting the cooling component 2, the mold is cooled comprehensively, making the heat absorption of the mold during the crystallization process uniform and thus improving the crystallization forming effect.

[0030] According to Figures 1-2 , an inlet hose 23 is inserted into the top end of the cooling water jacket 26. One end of the inlet hose 23 is installed with a water pump 24, and the water pump 24 is installed on one side of the flow - dividing chamber 8. A connecting pipe 27 is fixedly connected to the outside of the water pump 24. The bottom end of the connecting pipe 27 is installed with a water tank 28, and the water tank 28 is installed on the upper surface of the furnace body 1. By setting it like this, it is ensured that the coolant continuously cools the mold, improving the rationality of the mold structure.

[0031] According to Figures 1-2 , annular silica gel plates 25 are provided on the surfaces of the two partition plates 7 close to the cooling water jacket 26, and a moisture - absorbing coating is provided on the inner wall of the sleeve 4. By setting the annular silica gel plates 25 and the moisture - absorbing coating, the water vapor generated by cooling is absorbed, enhancing the moisture absorption inside the mold.

[0032] According to Figures 1-3The bottom ends of the crystal tube 9 and the graphite mold body 12 are both provided with reserved holes, and the two groups of reserved holes are connected. A graphite sleeve 11 adapted to the graphite mold body 12 is installed inside the furnace body 1, and an asbestos sleeve 14 is provided on the inner wall where the graphite sleeve 11 contacts the graphite mold body 12. By providing the graphite sleeve 11 and the asbestos sleeve 14, the sealing effect of the graphite sleeve 11 can reduce the direct contact between the outside air and the copper alloy melt, and the copper alloy melt is protected from oxidation.

[0033] according to Figure 4 A pointed conical copper protective sleeve 13 is provided between the bottom ends of the graphite sleeve 11 and the graphite mold body 12. By providing the pointed conical copper protective sleeve 13, the slag and oxides in the copper alloy solution are isolated to keep the solution pure.

[0034] Working principle: The staff injects the copper alloy melt into the furnace body 1 and injects the coolant into the water tank 28 in advance.

[0035] When the copper alloy melt reaches a certain water level, the conical copper protective sleeve 13 is set in a conical shape to separate the slag and oxide on the copper alloy solution on both sides, and the solution begins to flow into the graphite mold body 12, and then the solution is injected into the crystallization tube 9 through the reserved hole, and the prototype of the crystallizer is formed after a period of time; this process accumulates a lot of heat, and the water pump 24 is started to absorb the coolant from the water tank 28. The coolant enters the water pump 24 from the connecting pipe 27, and then flows into the water inlet hose 23 from the water pump 24. Due to the effect of gravity, it enters the cooling water jacket 26 through the water inlet hose 23. The crystallization tube 9 is cooled by continuously injecting coolant into the cooling water jacket 26. The water vapor generated in the process is absorbed by the connecting pipe 27, and some of the escaped water vapor is absorbed by the hygroscopic coating attached to the inner wall of the sleeve 4. After being fully formed, the coolant flows into the drainage pipe 21 along the drainage hose 22, and then flows out of the mold through the drainage pipe 21. After complete cooling, the staff opens the sealing cover 6, removes the crystallization tube 9, and then removes the mold.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
