Abstract

The invention provides a labyrinth sealing device which comprises sealing rails and guide rails. The sealing rails and the guide rails are all concave rails, a notch direction of each sealing rail is opposite to that of each guide rail, a first side wall of each guide rail is arranged in a concave groove of the corresponding sealing rail, a third side wall of each sealing rail is arranged in a concave groove of the corresponding guide rail, and a seal is filled in each guide rail. The labyrinth sealing device is reasonable in design, simple in structure, capable of realizing good sealing effect on the premise of low cost and good in resistance to high temperature, and has a positioning and guide function as well as a sealing function; a trolley is ensured to enter a furnace smoothly, damage of the trolley and the furnace due to the fact that the trolley impacts on the furnace is avoided effectively, and accordingly service life of production equipment is prolonged.

Description

technical field [0001] The invention relates to a sealing device, in particular to a labyrinth sealing device. Background technique [0002] When sealing is required in the production process, especially for high-temperature furnace body sealing, the design of the sealing structure and the selection of the sealant are related to whether it can ensure a good sealing effect and can be used for a long time in a high-temperature working environment. At the same time, under the premise of considering production efficiency, the overall production cost of the sealing device should be kept at a low level. The above-mentioned problems are the problems that should be solved in the design and production process of the sealing device in the production process. Contents of the invention [0003] The purpose of the present invention is to provide a labyrinth sealing device to solve the problem of how to ensure a good sealing effect when sealing a high-temperature furnace body an...
