Abstract
The utility model relates to a stack type external heat pre-oxidation furnace, which comprises a furnace body, a single filament array hearth at the lower part of the furnace body, 1-5 double filament array hearths arranged in parallel above the single filament array hearth, heaters arranged on the upper and lower walls of the hearths, heat insulation layers arranged between adjacent hearths, and hot blast pipes respectively arranged on both sides of the hearths and provided with opposite blast nozzles. The hot blast pipes in each hearth are respectively connected with external heating equipment; a filament array inlet and a filament array outlet are respectively arranged on the two ports of the hearths; filament guide rollers are arranged on the two lateral walls of the furnace body and opposite to the hearth ports; and exhaust air outlets are arranged on two upper lateral sides of the furnace body. The single filament array hearth allows only one array of filaments to pass through, and the double-filament array hearth allows two arrays of filaments to pass through in opposite direction. The utility model can operate independently or in combination with another; and the filament arrays pass through the hearths in stack manner to reduce space occupation and improve pre-oxidation efficiency.
Description
Technical field
The utility model relates to a kind of carbon fiber production equipment, the outer hot pre-oxidation furnace of particularly a kind of laminated type.
Background technology
Pre-oxidation furnace is an indispensable equipment of producing pre-oxidation operation in the carbon fiber process with the PAN precursor.Its process be with fiber in 200～300 ℃ of carrier of oxygen, heat-treat in certain force of strain, be the process that the dehydrogenation oxygenation carries out cyclisation.Fiber color in pre-oxidation becomes sepia again by white flavescence gradually, becomes black at last.Along with variations in temperature, fibre density is increasing, and final oxidation density should be controlled at 1.36～1.39g/cm3, provides condition to charing.Simple pre-oxidation furnace is formed pre-oxidation main product line by one or several pre-oxidation unit, with the formation temperature ladder and carry out the multistage drawing-off, and the tow one floor run, its production efficiency is low, and floor space is big.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed the outer hot pre-oxidation furnace of a kind of laminated type.Tow operates to the multilayer operation, has reduced floor space, has improved production efficiency.
The technical problems to be solved in the utility model is achieved through the following technical solutions, the outer hot pre-oxidation furnace of a kind of laminated type, be characterized in: it is provided with a body of heater, be provided with a monofilament burner hearth in the bottom of body of heater, the upper parallel of monofilament burner hearth be provided with 1 ~ 5 mariages burner hearth, the last lower wall of burner hearth is provided with heater, be provided with heat-insulation layer between the adjacent burner hearth, both sides in described burner hearth are respectively equipped with the hot blast jet pipe, the hot blast jet pipe of both sides in opposite directions have a fumarole, hot blast jet pipe in each burner hearth joins with the heating plant of peripheral hardware respectively, two-port place at burner hearth is provided with the tow gateway, all be provided with godet over against the burner hearth port, godet is contained on the two ends sidewall of body of heater, is provided with the waste discharge gas port above the body of heater both sides.The monofilament burner hearth is for passing row's silk in burner hearth, the mariages burner hearth then is the two-way two row's tow that penetrate in burner hearth.
The technical problems to be solved in the utility model can also come to realize that further described mariages burner hearth is provided with 3 by the following technical programs.
The utility model compared with prior art, be provided with a monofilament burner hearth in the bottom of body of heater, the top of monofilament burner hearth is provided with 1 ~ 5 mariages burner hearth, and the monofilament burner hearth is for passing row's silk in burner hearth, and the mariages burner hearth then is the two-way two row's tow that penetrate in burner hearth.Can adopt independent or two in parallel uses of separate unit, tow adopts the stacked method of operation in stove, reduced floor space, has improved the production efficiency of pre-oxidation.
