Abstract
The utility model relates to a counterweight device of a low-temperature carbide furnace, which belongs to the field of carbon fiber production equipment. The counterweight device is provided with a furnace, a muffle furnace, a fire resistant material layer, a heat preserving material layer and an electrical heater; a counterweight device support is arranged above the furnace; the counterweight device support is evenly arranged longitudinally along the furnace; the top of the counterweight device support is provided with a pulley; a lashing wire is wound on the pulley; one end of the lashing wire extends into a gap on the upper end of the furnace to hoist the upper wall of the muffle furnace, and the other end is provided with a counterweight. In the utility model, the counterweight device for pulling up is added to the muffle furnace of the low-temperature carbide furnace, so when the temperature is high and the upper plate of the muffle furnace expands, appropriate pulling force is used to pull up the redundant expanded part, so that the muffle furnace does not deform and collapse, the strength of the muffle furnace is improved and the service life is prolonged.
Description
Technical field
The utility model is a kind of carbon fiber production equipment, particularly a kind of counter weight device that is used for the low temperature carbonization furnace of carbon fiber production.
Background technology
As everyone knows, in carbon fiber production process, low temperature carbonization furnace is used for the low-temperature carbonization of fiber, under 300～1000 ℃ temperature fiber is handled, and fibre structure is changed.Its horse not is a rectangular seal chamber, and length is 15 meters, makes with heat-resisting steel sheet and plate.Need to solve the elevated temperature strength and the thermal expansion problem of furnace chamber.Because furnace chamber is not subjected to external force, after selecting the heat-resisting steel material of the corresponding trade mark for use, the elevated temperature strength problem of furnace chamber can be resolved, but this material linear expansion coefficient under 1000 ℃ temperature is 18 * E-6/ ℃, then horse not the swell increment of upper wall when being heated to 1000 ℃ be 1000 * 15000 * 18 * E-6=270 millimeter.Expand thus and caused a series of problem: the one, not will run into various resistances inevitably in the expansion process of upper wall horse, cause various distortion; The 2nd, in working order down, 15 meters horse not will be divided into several thermals treatment zone, and the horse of each thermal treatment zone not temperature is also inequality, promptly the horse of every section furnace chamber not upper wall different swell incremenies will be arranged, different swell incremenies then can produce very big internal stress.These two kinds of power will make the furnace chamber upper wall produce irregular distortion, can make when serious whole horse not upper wall subside, influence the normal use of carbide furnace.
Summary of the invention
The purpose of this utility model just is to overcome the deficiencies in the prior art, and a kind of low temperature carbonization furnace counter weight device is provided, and the furnace chamber upper wall is added counterweight, it is sling, to reduce subsiding of furnace chamber distortion generation, make that whole horse is not non-warping, the low temperature carbonization furnace of distortion.
The utility model adopts following technical solution: a kind of counter weight device of low temperature carbonization furnace, it be provided with body of heater, horse not, refractory masses, adiabator layer and electric heater unit, the body of heater top is equipped with the counterweight support, the counterweight support is vertically evenly arranged along body of heater, the top of counterweight support is fixed with pulley, be surrounded with lacing wire on the pulley, an end of lacing wire stretches into from the slit of body of heater upper end horse upper wall is not sling, and the other end of lacing wire is provided with balance weight body.
The beneficial effects of the utility model are: increased the counter weight device that upwards draws the horse of low temperature carbonization furnace on not, like this under high-temperature condition, horse is when not upper plate expands, be pulled upwardly with the part that it is unnecessary that suitable pulling force will expand, to guarantee that horse does not produce distortion, subsides, increase not intensity of horse, increase the service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1. horses not, 2. adiabator layer, 3. refractory masses, 4. electric heater unit, 5. counterweight support.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.
As shown in Figure 1, be provided with body of heater, horse not 1, refractory masses 3, adiabator layer 2 and electric heater unit 4, the body of heater top is equipped with counterweight support 5, counterweight support 5 is vertically evenly arranged along body of heater, the top of counterweight support 5 is fixed with pulley, pulley is surrounded with lacing wire, one end of lacing wire from the slit of body of heater upper end, stretch into horse not 1 upper wall sling, the other end of lacing wire is provided with balance weight body, according to the swell increment situation of each warm area the weight of balance weight body is installed suitably, shuts from body of heater inside with the slit of body of heater upper end with insulation material when the utility model uses.
The utility model compared with prior art, the horse of low temperature carbonization furnace has not increased the counter weight device that upwards draws, the use of such structure: under high-temperature condition, horse is when not upper plate expands, be pulled upwardly with the part that it is unnecessary that suitable pulling force will expand, to guarantee that horse does not produce distortion, subsides, increase not intensity of horse, increase the service life.
Therefore, not increase Weighting system adopt for horse, can solve at high temperature expansion, the problem on deformation of furnace chamber better, not furnace chamber can be because of expansion produce distortion, distortion at work to make horse, even subsides, with assurance low temperature carbonization furnace operate as normal.
