the utility model relates to the technical field of pipeline mixers, in particular to an adjustable gas guide device for a large-scale vapor deposition furnace.
Background art:
in industrial production, a large-scale vapor deposition furnace is utilized to carry out vapor deposition on carbon-carbon composite materials, gas such as natural gas or propane is introduced to decompose carbon atoms at high temperature and adsorb the carbon atoms in a carbon-carbon preform, the uniformity of the gas flow of the introduced gas (the gas is discharged from a gas column) determines the deposition effect of the preform, and the existing vapor deposition furnace can only be filled with products with set sizes according to design; however, in actual production, along with the increase of the size of the product, the dislocation of the gas columns occurs during charging, so that the gas columns are not positioned in the center of the product, two gas columns exist in one carbon-carbon prefabricated body, so that the gas flow is not uniform, the defects of carbon black, premature surface crusting of the prefabricated body, less internal deposited carbon and the like occur after the product is discharged from the furnace, and the product deposition effect is influenced.
The utility model has the following contents:
an object of the utility model is to provide an adjustable gas guide device for large-scale vapor deposition stove.
The content of the utility model is as follows: an adjustable gas guide device for a large-scale vapor deposition furnace comprises a Z-shaped telescopic gas guide pipe assembly.
Furthermore, the telescopic air duct assembly sequentially comprises a first right-angle bent pipe, a connecting straight pipe and a second right-angle bent pipe from left to right, the outer circumferential surface of the first right-angle bent pipe and the outer circumferential surface of the second right-angle bent pipe are both in sliding connection with the inner circumferential surface of the connecting straight pipe, the other end of the second right-angle bent pipe is in sliding connection with the inner circumferential surface of the air guide straight pipe, the first right-angle bent pipe is in transition fit with the connecting straight pipe, and the second right-angle bent pipe is in transition fit with the connecting straight pipe.
Furthermore, a limiting snap ring is fixedly connected in the connecting straight pipe and the air guide straight pipe concentrically.
Furthermore, threaded through holes are formed in the outer circumferential surfaces of the two ends of the connecting straight pipe and the outer circumferential surfaces of the two ends of the air guide straight pipe, and locking screws are screwed in the threaded through holes.
The utility model has the advantages that: the utility model has simple structure, the length of the telescopic air duct component is designed to be adjusted according to the offset position of the air column, so that the air inlet is positioned in the center of the product, and each column of the product is provided with only one air inlet, thereby ensuring that the product in the furnace is uniformly ventilated, the deposition effect is good, and the carbon black on the surface of the product is reduced or no carbon black; the deposition quality of the product is improved, and the method is worthy of wide popularization and application.
