An air lock for carbon fiber pre-oxidation equipment

Abstract

The invention relates to an air lock of carbon fiber pre-oxidation equipment. The air lock comprises two support columns, a sealing plate and bases, wherein the sealing plate is fixed between the two support columns; carbon fiber inlets, carbon fiber outlets and a sealing pad are arranged on the sealing plate; each base is arranged at the bottom of the corresponding support column; a strong exhaust channel is arranged inside each support column. Air locks are creatively added to the front end and the rear end of the pre-oxidation equipment, which is the unprecedented pioneer in all equipment at home and abroad; therefore, the energy consumption is reduced by 45%, the product quality can be improved by 1-2 grades, and the rate of finished products can be increased to 99.98%.

Description

technical field [0001] The invention relates to the field of carbon fiber production equipment manufacturing, in particular to an air lock used for carbon fiber pre-oxidation equipment. Background technique [0002] With the rapid development of science and technology, people pay more and more attention to the production and application of carbon fiber. The production of carbon fiber is roughly composed of two parts, one is the production process technology, and the other is the equipment manufacturing technology. At present, my country's carbon fiber production technology has initially taken shape. If you want to further improve production conditions and perfect production steps, equipment manufacturing and supporting technology are particularly important. Only with advanced and complete equipment configuration can mature technology be displayed. Some engineers and technicians often ignore or fail to fully understand the function and use of the device, and fail to achieve p...

AI Technical Summary

Problems solved by technology

[0004] The main process of carbon fiber production starts from the oxidation process. The pre-oxidation process is of great significance in the production of carbon fiber. The fiber is heated in the oxidation equipment to the step temperature required by the process. Due to physical changes, the carbon fiber needs to stay in the equipment continuously for about About 320 minutes, because the carbon fiber needs to stay in the equipment for a long time, the existing oxidation equipment cannot meet the needs of the fiber process due to the length, and the method of connecting multiple sets is required

In the way of multi-unit connection, when the carbon fiber undergoes cyclic heat physical changes in the S-type equipment, the exposed part of the carbon fiber outside the equipment loses its basic process performance because it fails to meet the continuous physical change requirements, resulting in a waste of resources.
