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
The present invention relates to carbon fibre producing facility and manufacture field, particularly relate to a kind of air lock for carbon fiber pre-oxidation equipment.
Background technology
Along with scientific and technical develop rapidly, carbon fiber is produced with application and is more and more valued by the people, and the production of carbon fiber is roughly comprised of two large divisions, and the one, production Technology, the 2nd, equipment manufacturing technology.At present, China's carbon fiber production Technology is one-step forming just, wants further to improve working condition, improve production stage, equipment is manufactured with supporting technology and is just seemed and be even more important, and has had advanced, perfect equipment configurations, just can show ripe technology.Some engineers and technicians often ignores or fails to understand completely the function and usage of device, at device design aspect, fail to reach perfect, actual capabilities have been ignored the basic function of device, cause product quality to decline, lose product good location, reduce value of the product, so, Perfected device function, improves device performance and just seems and be even more important.
In carbon fiber production process, it is extremely important that preoxidation process seems, because fiber requirement in oxidizing process will have continuous, continual physical change process.Existing device can not meet the uninterrupted physical change requirement of fiber, but continuing to use to be interrupted always, changes, and has both consumed mass energy, causes again product quality to decline, and cost rises.Therefore, we find in production practices process, manufacture the requirement that pre-oxidation facilities air locking device can meet uninterruptedly, continuous physical changes for the production of carbon fiber.
The master operation that carbon fiber is produced is from oxidizing process, preoxidation process is of great significance in the production of carbon fiber, fiber is heated to the step temperature that technique needs in oxidation furnaces, carbon fiber need to uninterruptedly rest in equipment about approximately 320 minutes because of physical change, because of carbon fiber need to be in equipment the time of staying longer, existing oxidation furnaces, because length reason all can not meet fibre technology needs, need to adopt many methods that continue.In the mode continuing at Duo Tai, carbon fiber circulates while being heated physical change in through S type equipment, and carbon fiber is exposed to be required to lose basic technology performance because failing to meet continuous physical variation in equipment exterior portion, has caused the waste of resource.
How to found a kind of good sealing effect, can avoid the air lock for carbon fiber pre-oxidation equipment that in carbon fiber preoxidation process, exposed part lost efficacy, in the industry cycle have a very important role.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of good sealing effect, can effectively avoids exposed part in carbon fiber preoxidation process to lose efficacy, improve the air lock of raw material utilization rate.
The invention provides a kind of air lock for carbon fiber pre-oxidation equipment, its special character is, comprise pillar, closure plate and base, described closure plate is fixed between two pillars, closure plate is provided with carbon fiber import, carbon fiber outlet and sealing gasket, the bottom of every pillar is provided with base, and pillar inside is provided with the discarded passage of forced-ventilated.
Further, described air lock is arranged on the two ends of pre-oxidation equipment by flange form or overlap joint, and the closure plate of one end, fiber outlet place is provided with waste gas nature discharge orifice.
Further, in described closure plate, be respectively equipped with two carbon fiber imports and two carbon fiber outlets.
Further, described closure plate is made by stainless steel material and transparent high temperature resistant material, and described transparent high temperature resistant material is safety glass or lucite.
The present invention has following advantage:
Air lock and oxidation furnaces are tightly connected, and guarantee waste gas and Free-flow is not outdoor to equipment and air lock with the temperature gas of notch cuttype.When fiber is passed through to S type, by the exposed fibrous encapsulation in equipment exterior portion, only see fiber one-in-and-one-out in equipment, lose and have fiber exposed in equipment outside, guarantee the continuity of fibrous physics During.
The method will guarantee fiber oxidation technique needs, Improving The Quality of Products, capable of reducing energy consumption more than 20%, 1-2 the grade of can improving the quality of products, as reached T400 by T300, increase economic benefit 35%, reduced cost, improved economic benefit, and met fiber continuous physical and changed needs, finished product rate can be greatly to 99,98%.。
Fiber preoxidation apparatus and process technology that the present invention is perfect, for producing high-performance, high-quality carbon fiber provides complete, reliable technology.
The height of air lock and width import and export overall height according to oxidation furnaces two ends and width dimensions is made, good sealing effect, and closure plate is sealing couple to be installed and with the assembly parts of importing and exporting with fiber of sealing gasket, repair demolition is convenient.
Closure plate adopts corrosion resistant plate and is provided with safety glass or lucite, neither affects sealing effect, can conveniently observe again product operation.
