Device for continuous carbon felt impregnation

Abstract

A device for continuous carbon felt impregnation comprises a frame, a carrier shaft, a feed roll shaft, an impregnation tank and a discharge roll shaft, wherein the carrier shaft, the feed roll shaft, the impregnation tank and the discharge roll shaft are sequentially arranged on the frame. A drive motor is arranged between the feed roll shaft and the discharge roll shaft, the drive motor is respectively connected with the feed roll shaft and the discharge roll shaft through a transmission device, impregnation roll shaft brackets are disposed inside two ends of the impregnation tank respectively, an impregnation roll shaft is arranged on the impregnation roll shaft brackets, and a slanting guide board is disposed below the discharge roll shaft and connected with the impregnation tank. Thedevice can be used for continuous, mechanical and automatic impregnation for carbon felts, labor intensity can be reduced greatly, impregnation efficiency can be improved, and product quality stability can be improved.

Description

technical field [0001] The invention relates to a dipping device, in particular to a device for continuous dipping of carbon felt. Background technique [0002] Carbon felt is a felt-like carbon material composed of carbon fibers. Carbon felt not only has the characteristics of high temperature resistance, corrosion resistance, and non-melting of general block carbon materials, but also has the properties of softness, elasticity, small volume density, and small thermal conductivity of fibrous carbon. It is an excellent thermal insulation material. hot material. At present, carbon felt is widely used in high-temperature furnaces in vacuum or non-oxidizing atmospheres, high-temperature induction furnaces and vacuum coating furnaces. [0003] The thickness of ordinary soft carbon felt is 8~10mm. In order to make the carbon felt reach the required thickness of the insulation layer, the 8~10mm carbon felt must be cut and wrapped in several layers. In order to improve the perfo...

AI Technical Summary

Problems solved by technology

[0004] At present, the preparation process of cured carbon felt mostly adopts manual brushing and dipping. Manual operation often leads to local accumulation of glue on the surface of the carbon felt, less penetration into the interior of the carbon felt, and the amount of glue permeation in each area of ​​the carbon felt is also very uneven.

This causes the product to be prone to delamination, deformation, wrinkling, etc. in the subsequent process, which greatly affects the quality of the product.

For similar products, due to the different operating habits of workers and the understanding and understanding of product requirements, the operating effect is very different, and the product quality is difficult to stabilize.

At the same time, the production efficiency of manual brushing and dipping is low, the waste of glue is serious, and the production environment is harsh

Therefore, the manual brushing and dipping method is difficult to meet the requirements of mass production of products, and it is difficult to meet the market's increasing demand for product quality
