Description

Structure of big silk bundle oxidation oven stacking arrangement

Technical Field

The utility model relates to the technical field of large-tow carbon fiber production equipment, in particular to a structure of stacked arrangement of large-tow oxidation furnaces.

Background

In the production of carbon fibers, pre-oxidation is a critical process, the function of which is to convert a precursor of a linear molecular chain structure into a heat-resistant trapezoid molecular structure, and the process is closely related to the performance of the carbon fibers and also to the manufacturing cost of the carbon fibers.

The existing large-tow oxidation furnace equipment is assembled after scattered small modules arrive at the site of a user, and parts and components produced in the process can be effectively monitored and controlled at a manufacturer. The subsequent assembly is carried out on the user site, and the supervision and control of the manufacturer on the user site cannot be effectively implemented in the factory of the manufacturer because the construction condition is not complete at the manufacturer, so that the assembly machining precision cannot be effectively ensured in the case of assembly omission, and the construction confusion is easily amplified.

And all parts arrive at the user site to be assembled, constructors are unfamiliar with equipment parts, goods arrive at the disordered management of the user site, the site construction space is small, the construction equipment is not perfect, the manpower resources input at the site are more, but the benefit harvesting is low, and the like, so that the construction period is directly or indirectly prolonged.

In addition, the existing structural mode utilizes a building lap joint to place an oxidation furnace on a second-floor platform, so that an upper oxidation furnace mode and a lower oxidation furnace mode are formed. The stable placement of the oxidizing furnace is required for the platform, and the firm and reliable structure of the oxidizing furnace requires the selection of high-performance steel materials and a firm and large structure, so that the production cost is high. Because the oxidizing furnace can be assembled only by the second-floor platform, the built second-floor platform has a certain space to influence the assembly of the first-floor oxidizing furnace. If the first-floor oxidizing furnace is assembled, then the second-floor platform is built, and then the second-floor oxidizing furnace is assembled, the construction period is greatly prolonged.

It follows that the oxidation ovens used in the production of large tow carbon fibers of the prior art do not facilitate rapid assembly in the field.
