Embodiment Construction

[0026] The present invention is used for the high-temperature furnace sealing device of continuous production carbon fiber such as figure 1 As shown, it can be applied to the entrance and exit of the pre-oxidized fiber tow 7 of the high temperature furnace 8, mainly composed of a sealed chamber 3 and a number of air intake components 2, and one end of the sealed chamber 3 is a gap for the fiber tow to enter and exit 6. The gate-type structure of the upper gate 4 and the lower gate 5 is used to adjust the width of the gap, and the other end communicates with the furnace mouth of the high-temperature furnace 8, and is usually connected by fasteners; several air intake components 2 are arranged in the sealed chamber 3 One side, upper and lower sides or surroundings of the main body are mainly composed of intake pipe 9, expansion chamber 10, rectification chamber 11, and air inlet 14; the number of intake components 2 is determined by the size of the furnace mouth of the high-tempe...

Abstract

The invention relates to a high-temperature furnace sealing device for continuously producing carbon fibres. The device comprises a sealing chamber (3) and a plurality of intake components (2) vertically arranged on the outer wall of the sealing chamber (3); a clearance (6) for fibre tows to enter or go out is reserved at one end of the sealing chamber (3) and the other end of the sealing chamber(3) is communicated with a high-temperature furnace (8); and an air inlet (14) is arranged between the sealing chamber (3) and each of the intake components (2). The device solves the problems of complex structure, poor sealing effect, high air consumption and inconvenient cleaning and maintenance of the traditional high-temperature furnace sealing device for continuously producing the carbon fibres, and can prevent air outside the high-temperature furnace from being diffused into the furnace and carbonized waste gas in the furnace from being exhausted into a room.

Description

technical field [0001] The invention belongs to the field of new material production, and relates to a sealing device, in particular to a high-temperature furnace sealing device for continuous production of carbon fibers. Background technique [0002] Carbon fiber is a new type of non-metallic material with a series of excellent properties such as high specific strength, high specific modulus, high temperature resistance, corrosion resistance, creep resistance, low thermal expansion, high electrical and thermal conductivity, and self-lubrication; and as a fiber, it also has Softness, weavability, and weaving are widely used in cutting-edge fields such as aerospace, national defense and military, as well as civilian industries such as high-end sporting goods and medical equipment. It has become one of the main reinforcements of advanced composite materials and is known as the mid-century The most vital new material. [0003] Carbon fiber is made by pre-oxidizing organic fibe...
