Abstract
The utility model relates to a carbonization furnace for producing carbon fibers, which comprises a furnace lining, a heat-insulating layer and a heating body, and is characterized in that an adsorption band is arranged above a hearth, both ends of the adsorption band extend out of the furnace through the furnace lining, and the adsorption band is pulled, so that one part thereof can move out of the hearth, and the other part thereof enters the hearth. The utility model has the characteristics that tar can be effectively adsorbed and is not easy to shed by arranging the adsorption band in the hearth, and meanwhile, the adsorption band accumulated with the tar also can move out of the furnace for cleaning, so that carbon fiber wires in various specifications can be produced through the carbonization furnace.
Description
Technical field the utility model relates to a kind of equipment of producing carbon fiber.
Background technology is in the process of producing carbon fiber, when carbon fiber material carries out carbonization treatment under 300～600 ℃ temperature conditions, produce a large amount of tar, attached to being shed to again just on the filament of carbonization treatment after the assembly of the tar on the hearth wall, therefore because tar is burning easily at high temperature, cause fracture of wire in the high temperature cabonization processing meeting of postorder because of the burning of tar.In order to prevent adhering to of tar that mostly adopt suction method with the tar sucking-off at present, the deficiency of this method is: the excessive product that causes easily of suction burns, and suction is too small, and the removing of tar is not thorough, also easy blocking pipe, and the mediation of pipeline is difficulty relatively.
The summary of the invention the purpose of this utility model is to provide a kind of carbide furnace of producing carbon fiber, and it can prevent coming off of tar effectively and remove tar, thereby has realized the continuous production of carbon fiber.
The purpose of this utility model is such realization: a kind of carbide furnace of producing carbon fiber, comprise furnace lining, heat-insulation layer, heater, and its special character is to be provided with movably adsoption band above burner hearth, and the two ends of adsoption band are outside furnace lining extends to stove.
Described adsoption band is to be made of interconnective lath, has certain clearance between lath and the lath, forms the adsoption band that has the slit.
The main carbide furnace of the production carbon fiber that constitutes by furnace lining, heat-insulation layer, heater, above burner hearth, be provided with adsoption band, its two ends extend to outside the stove through the furnace lining opening, the length of adsoption band is 2 times of carbide furnace length at least, when a part of adsoption band is outside supporting guide shifts out burner hearth, another part then enters in the burner hearth, can remove cleaning to shifting out the outer adsoption band of burner hearth like this.The furnace lining opening can seal protection with nitrogen or other inert gas, and it is manual or electronic that the moving of adsoption band can be adopted.In order to make adsoption band have adsorption effect preferably, the adsoption band that the utility model provides is to be made of the lath that interconnects and have a certain interval.The thickness of lath is preferably between 8～15 millimeters, and the gap between lath and the lath is preferably between 0.8～1.5 millimeter.Adsoption band also can be other structure.
Characteristics of the present utility model are: adsoption band tar adsorption and difficult drop-off effectively are set in burner hearth, simultaneously can also shift out the stove place and clean accumulating the adsoption band that tar is arranged, neither can influence the continuous production of carbon fiber, can not occur again that tar comes off and the disconnection that causes carbon fiber, so this carbide furnace can be produced the carbon fiber wire of all size.
Description of drawings
Fig. 1 is the simplified schematic diagram of analysing and observe of furnace lining part of the present utility model;
Fig. 2 is the structural representation sketch of adsoption band of the present utility model;
Fig. 3 is the structural representation of the utility model lath.
The specific embodiment
It is all identical with existing carbide furnace to constitute structures such as furnace lining of the present utility model, heater, heat-insulation layer, and the import of carbide furnace and port of export symmetry, so Fig. 1 does the cut-away view of picture port of export furnace lining.The both sides that are positioned at the adsoption band (2) of burner hearth (1) top ride on the guide rail, and its two ends extend out to outside the stove from furnace lining (3) is open-ended, and during carbonization treatment, furnace lining is open-ended to seal with nitrogen.The mobile of adsoption band is to drive by live-roller (4) in this programme, position relative with adsoption band both sides openings (13) on the live-roller is provided with cam, double wedge was inserted in the perforate of driving-chain successively when live-roller rotated, the drive adsoption band moves, its part is shifted out in burner hearth, and another part enters in the burner hearth.Adsoption band is to be interconnected to constitute by the white steel plate bar (5) that two ends have a connecting hole (12), see Fig. 2, Fig. 3, the both sides of adsoption band are connected with driving-chain with holes (6), the thickness of white steel plate bar (7) is 10 millimeters, gap between lath and the lath (8) is 1 millimeter, it can be by being provided with 1 millimeter, and it can be realized by the pad that 1 millimeters thick is set.(9) are converter nose among Fig. 1, and (10), (11) are adpting flange.
Claims (2)
1. produce the carbide furnace of carbon fiber, comprise furnace lining, heat-insulation layer, heater, it is characterized in that being provided with movably adsoption band above burner hearth, the two ends of adsoption band are outside furnace lining extends to stove.
2. the carbide furnace of production carbon fiber according to claim 1 is characterized in that: adsoption band is to be made of interconnective lath, has certain clearance between lath and the lath, forms the adsoption band that has the slit.
