[0002] After graphite is produced, there are still a certain amount of impurities inside it. When high-purity graphite products are needed, the graphite products often need to be purified. Generally, the graphite products are heated at high temperatures in a purification furnace to burn the impurities and improve the purity of the graphite.

[0003] High-temperature purification equipment is the key core equipment for obtaining high-purity graphite products. During each operation and maintenance process, the high-temperature purification equipment needs to clean the carbon impurities attached to the inner surface of the process gas inlet pipeline to ensure the smooth flow of the process gas inlet pipeline; before disassembling the inlet pipeline, the gas distributor on the inlet pipe needs to be removed, and then the tooling is used to disassemble the process inlet pipeline. Before disassembling the gas distributor, it is necessary to remove the gas distributor from the graphite platform. The gas distributor is a graphite product with a diameter of 1500mm and a thickness of 30mm. It is difficult to disassemble manually, and it increases the equipment maintenance time. There is a risk of damage during the disassembly process. Utility Model Content

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions.

[0006] A device for facilitating the disassembly and assembly of a gas distributor plate of a high-temperature purification equipment comprises a gas distributor plate and a disassembly tool; the gas distributor plate comprises a central air distributor cover and a gas distributor plate edge plate, the central air distributor cover and the gas distributor plate edge plate are threadedly connected, the central air distributor cover is connected to a process gas pipeline; the central air distributor cover is provided with a central air distributor cover vent hole; the disassembly tool comprises a connecting part and a disassembly part, the disassembly part is connected to the connecting part, the connecting part is provided with a hand-held part, the disassembly part corresponds to the number and position of the vent holes of the central air distributor cover, the disassembly part penetrates into the vent holes of the central air distributor cover to cooperate with rotation, and is used to separate the central air distributor cover and the gas distributor plate edge plate.

[0007] Furthermore, the air disk plugging cover is a disc structure, the air distributor plate edge plate is an annular structure, and the air disk plugging cover is connected to the center of the air distributor plate edge plate.

[0008] Furthermore, the process gas pipeline is connected to the bottom of the hollow air disk cover; a graphite platform is provided on the lower surface of the edge plate of the gas distribution plate, and the graphite platform, the gas distribution plate and the process gas pipeline are all arranged in the furnace body.

[0009] Furthermore, two air holes of the air disc plugging cover are symmetrically arranged on the air disc plugging cover; correspondingly, two disassembly parts are connected to the bottom of the connecting part, and hand-held parts are respectively arranged at both ends of the connecting part.

[0010] Furthermore, the connecting part and the hand-held part are an integrated structure.

[0011] Furthermore, the connecting part and the disassembling part are both rod-shaped structures, and the disassembling part is vertically connected to the bottom of the connecting part.

[0012] The beneficial effects of the utility model compared with the prior art are:
