Carbon fiber is phosphorus content higher than 90% inorganic polymer fiber.Wherein phosphorus content is higher than 99% title graphite fibre.The similar Delanium of microstructure of carbon fiber is random graphits structure.Spacing between each aspect of carbon fiber is about 3.39 to 3.42A, each carbon atom between each parallel aspect, and arrangement is regular like that not as graphite, borrows between layers Van der Waals force to link together.
Carbon fiber is compared with traditional glass fibre, and Young's modulus is that they are more than 3 times; It is compared with Kafra fiber, and Young's modulus is its 2 times of left and right, insoluble not swollen in organic solvent, acid, alkali, and corrosion resistance is outstanding.
Carbon fiber is a kind of new material of mechanical property excellence.Carbon fiber hot strength is about 2 to 7GPa, and stretch modulus is about 200 to 700GPa.Density is about 1.5 to 2.0 grams every cubic centimetre, and this,, except outside the Pass having with precursor structure, depends mainly on the temperature that charing is processed.General through 3000 ℃ of graphitization processing of high temperature, 2.0 grams every cube li of density reachable.Add its very light in weight, its proportion is also lighter than aluminium, and less than 1/4 of steel, specific strength is 20 times of iron.The thermal coefficient of expansion of carbon fiber is different from other fiber, and it has anisotropic feature.The specific heat capacity of carbon fiber is generally 7.12.Thermal conductivity raises and to decline that to be parallel to machine direction be negative value (0.72 to 0.90) with temperature, and is on the occasion of (32 to 22) perpendicular to machine direction.The ratio resistance of carbon fiber is relevant with the type of fiber, and in the time of 25 ℃, high-modulus is 775, and high-strength carbon fiber is every centimetre 1500.This makes carbon fiber have the highest specific strength and specific modulus in all high-performance fibers.The metal materials such as same titanium, steel, aluminium are compared, and carbon fiber has the features such as intensity is large, modulus is high, density is low, linear expansion coefficient is little in physical property, can be called the king of new material.
At present the flue dust in retort is mainly tar liquid when high temperature, can solidify and stick on inner-walls of duct when low temperature, need to stop producing while being generally cleaning, is unfavorable for enhancing productivity, and causes the waste of resource.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high-temperature flue gas self-timing dust arrester for carbon fiber field is provided.
The purpose of this utility model is achieved through the following technical solutions:
For the high-temperature flue gas self-timing dust arrester in carbon fiber field, it comprises variable-frequency motor and heat pipe, it is characterized in that, variable-frequency motor is connected with one end of screw-thread drive shaft by scroll bar, and other one end of screw-thread drive shaft is connected with composite doctor; The connecting ring that composite doctor is comprised of three steel discs, each connecting ring is connected with C shape scraping blade by connecting rod; Heat pipe top arranges blast pipe, and heat pipe bottom arranges blow-off pipe, and a valve is set between blow-off pipe and heat pipe.
Described variable-frequency motor, by motor controller controls, carries out timing automatic cleaning when normal production; To reach, do not stop producing the effect that can clear up heat pipe.
Whether described blow-off pipe is arranged in collector, and collector is also provided with a visible mirror, be used for observing discarded object and fill up in collector.
Space between the connecting ring of described composite doctor is 1-5mm.
Three connecting rings of described composite doctor interlock on screw-thread drive shaft.
Between three C shape scraping blades of described composite doctor, be 120 degree and distribute, form a circle.
The radius that welds C shape scraping blade on each steel disc of described composite doctor is the same with the radius of heat pipe.
The port at the C shape scraping blade two ends of described composite doctor concaves, and groove, plays the effect of dust out.
Compared with prior art, good effect of the present utility model is:
The utility model can, not stopping, under the state of producing, can carrying out the cleaning of heat pipe by self-timing, improve the efficiency of producing.
C shape scraping blade of the present utility model plays the effect of scraping and the effect of removing.
[accompanying drawing explanation]
Fig. 1 structural representation of the present utility model;
The schematic diagram of Fig. 2 composite doctor of the present utility model;
Being labeled as in accompanying drawing: 11, heat pipe, 12 blast pipes, 13 blow-off pipes, 14 valves, 15 collectors, 21 variable-frequency motors, 22 scroll bars, 31 screw-thread drive shafts, 32 composite doctors, 321 connecting rings, 322 connecting rods, 323 scraping blades.
[specific embodiment]
A kind of specific embodiment of the high-temperature flue gas self-timing dust arrester for carbon fiber field is below provided.
Embodiment 1
Refer to accompanying drawing 1,2, a kind of high-temperature flue gas self-timing dust arrester for carbon fiber field, it comprises variable-frequency motor and heat pipe, it is characterized in that, variable-frequency motor is connected with one end of screw-thread drive shaft by scroll bar, and other one end of screw-thread drive shaft is connected with composite doctor; The connecting ring that composite doctor is comprised of three steel discs, each connecting ring is connected with C shape scraping blade by connecting rod; Heat pipe top arranges blast pipe, and heat pipe bottom arranges blow-off pipe, and a valve is set between blow-off pipe and heat pipe.
