Abstract
The utility model relates to a preliminary heat treatment in oxidizing stove of carbon fiber belongs to carbon fiber apparatus for producing field. Be equipped with the furnace body, a serial communication port, the upper end of furnace body is linked together through the air outlet of air -supply line with the fan, the last lower extreme of air -supply line is installed air inlet plate respectively and is reached air inlet plate down, air inlet plate went up processing under upward air inlet plate reached there is the fresh air inlet, the air intake of fan connects the fresh wind tube, install the heater between the air intake of fan and the fresh wind tube, the furnace body lower extreme is through return air pipe connector exhaust system, install the return air board in the backwind tube, processing has the exhaust vent on the return air board, install axial direction parallel's roller in the furnace body, stagger in the axle center of two adjacent roller from top to bottom. The utility model discloses hot -blastly blow in the furnace chamber by the furnace body top, from stove lower curtate discharge furnace chamber, netted arranging is overlooked as to the fibre in the furnace chamber for hot -blast all silk bundles of evenly blowing over avoid the left and right sides temperature of silk bundle horizontal direction uneven, thereby improve the quality and the production efficiency of product.
Description
Technical field
The utility model relates to carbon fiber production apparatus field, is a kind of pre-oxidation furnace of carbon fiber in detail.
Background technology
As everyone knows, the workflow of current pre-oxidation furnace can be sketched as the entrance of tow by body of heater two ends enters in burner hearth.The hot blast of ozone and circulation is constantly repeatedly after heating, being recycled blower fan blows on air supply line, this pipeline there are many baffle plates, controlling hot blast level by the size controlled between baffle openings blows on tow, the inlet scoop that hot blast is recycled again blower fan through the reaction heat of tow is taken away, and so ceaselessly circulates.Oxidation reaction produces a large amount of toxic gas and is disposed to incinerator by the discharge duct blower fan at body of heater top, is finally discharged in air.Oxidation reaction also needs sufficient oxygen and contacts with tow, so it is negative pressure a little that air exhauster will allow in stove, ensures oxygen and enters in furnace chamber through sending fresh air pipeline.
Existing equipment because of hot blast be blow to tow about level, the left and right sides along tow direction is kept away and unavoidably can be produced the temperature difference, makes both sides temperature uneven, obviously produces oxidation effectiveness inequality, the situation that product quality differs to product.
Summary of the invention
Uneven in order to overcome existing pre-oxidation ubiquity isothermal region temperature, the not first-class problem of the left and right sides, Product Level direction quality, a kind of pre-oxidation furnace of carbon fiber is provided, the uniform temperature fields of heating system, temperature gradient distribution is reasonable, wind direction, preferably perpendicular to tow, has uniform air to flow in fiber band.
The utility model solves the technical scheme that its technical problem adopts: a kind of pre-oxidation furnace of carbon fiber, be provided with body of heater, it is characterized in that, the upper end of body of heater is connected with the air outlet of blower fan through blast pipe, the upper and lower side of blast pipe is separately installed with enterprising aerofoil and lower air intake plate, enterprising aerofoil and lower air intake plate are processed with fresh air inlet, the air inlet of blower fan connects fresh wind tube, between the air inlet of blower fan and fresh wind tube, heater is installed, body of heater lower end connects gas extraction system through backwind tube, return air plate is installed in backwind tube, return air plate is processed with exhaust vent, axially parallel roller roll shaft is installed in body of heater, stagger in the axle center of two neighbouring roller roll shafts.
The beneficial effects of the utility model are, hot blast is blown into furnace chamber by body of heater top, discharge furnace chamber from stove lower curtate, fiber is overlooked as netted arrangement in furnace chamber, make hot blast evenly blow over all tow, avoid the left and right temperature of tow horizontal direction uneven, thus improve quality and the production efficiency of product.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structure principle chart of the present utility model.
Fig. 2 is the left view of the utility model body of heater inner chamber.
Fig. 3 is the canoe schematic diagram of the utility model fibre bundle on roller roll shaft.
1. bodies of heater, 2. blast pipe, 3. backwind tube, 4. blower fan, 5. heater, 6. fresh wind tube, 7. gas extraction system in figure, 8. return air plate, 9. descends air intake plate, 10. fibre bundle, 11. enterprising aerofoils, 12. roller roll shafts.
Detailed description of the invention
As Fig. 1, Fig. 2, shown in Fig. 3, the utility model is provided with body of heater 1, the upper end of body of heater 1 is connected through the air outlet of blast pipe 2 with blower fan 4, the upper and lower side of blast pipe 2 is separately installed with enterprising aerofoil 11 and lower air intake plate 9, enterprising aerofoil 11 and lower air intake plate 9 are processed with fresh air inlet, the air inlet of blower fan 4 connects fresh wind tube 6, between the air inlet of blower fan 4 and fresh wind tube 6, heater 5 is installed, body of heater 1 lower end connects gas extraction system 7 through backwind tube 3, return air plate 8 is installed in backwind tube 3, return air plate 8 is processed with exhaust vent, axially parallel roller roll shaft 12 is installed in body of heater 1, stagger in the axle center of two neighbouring roller roll shafts 12.
The utility model hot blast, from furnace roof portion, from up to down blows into furnace chamber, then discharges furnace chamber by blower fan from bottom; Enterprising aerofoil, lower air intake plate and return air plate are orifice plate, and bore size differs, and ensure the uniformity of hot blast at furnace chamber Inner eycle; The waste gas that oxidation furnace produces is discharged by the backwind tube of bottom, after burning disposal, discharge air again; New wind is entered by heater bottom, and after heating, recirculation supplements into furnace chamber; Before and after body of heater, roll shaft is all grooved roller, and staggers in adjacent upper and lower two roll shaft centers, makes fibre bundle overlook as netted arrangement in furnace chamber; Heater is positioned at circulating fan air intake vent, the heat of supplementary furnace internal loss at any time.
