Embodiment Construction
[0012] In order to make the technical means, technical features, invention objectives and technical effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0013] Such as figure 1 As shown, it is a furnace hearth for a carbon fiber high-temperature furnace of the present invention, which includes a graphite furnace hearth 1 and a furnace shell 2 arranged outside the furnace hearth 1. An insulating layer 3 is arranged on the periphery of the furnace hearth 1, and the heat insulating layer 3 passes through the furnace shell 2. The circumferentially arranged furnace and heat-insulating roof pressing device 4 can adjust the position of the furnace 1, and the heat-insulating layer 3 and the furnace 1 can be closely attached by adjusting the furnace pressing device 4 .
[0014] In the present invention, the insulation layer 3 has several layers, and a certain gap 5 will be eject...

The invention discloses an anti-loose device for hearth and heat preservation used for a carbon fiber high temperature furnace, comprising a hearth, a heat preservation layer and a hearth casing which are arranged on the outside of the hearth successively. The compact degrees of the hearth casing and the heat preservation layer are adjusted by tightening devices which are circumferentially disposed on the hearth casing. The heat preservation layer is circumferentially added to the hearth of the high temperature furnace, and mounting holes are opened on the hearth casing of the high temperature furnace. The hearth having regulating function and heat preservation tightening devices are installed by the mounting holes. By adjusting the tightening devices, the compact degrees between the hearth casing and the heat preservation layer can be controlled to enable the backlashes to maintain between the heat preservation layer and the hearth casing. Therefore, the hearth casing and the heat preservation layer can be always maintained compactly, to maintain the air impermeability of the hearth and the heat preservation effect.
Description
technical field [0001] The invention relates to a carbon fiber high-temperature furnace, in particular to a hearth for a carbon fiber high-temperature furnace. Background technique [0002] The current high-temperature furnaces all adopt the splicing structure of graphite furnace and insulation layer for internal insulation. However, under long-term high temperature, graphite and insulation materials will be gradually cavitated. As the use time increases, the structure of the furnace and insulation will deteriorate If it is loose, the airtightness of the furnace and the insulation effect of the insulation layer will be reduced, and even the furnace will collapse, which greatly reduces the service life of the furnace. Contents of the invention [0003] The purpose of the present invention is to solve the problem of poor air tightness and thermal insulation effect of the furnace in the prior art, and provide a furnace for a carbon fiber high-temperature furnace. [0004] Th...
