Abstract
The utility model discloses a rotary kiln air-supplying device for producing carbon fiber materials and relates to rotary kiln air-supplying devices. The rotary kiln air-supplying device comprises a nozzle body (5), and a first flange (3) is placed above the nozzle body (5). The rotary kiln air-supplying device is characterized in that a second flange (4) is arranged above the first flange (3), reinforcing ribs (2) are arranged on the inner wall of the nozzle body (5), a discontinuous wind-fixing plate (1) is arranged on the center line inside the outlet of the nozzle body (5), and two sides of the discontinuous wind-fixing plate (1) are connected with two side walls at two sides of the outlet. An inclined angle (alpha) between the discontinuous wind-fixing plate (1) and the center line of the rotary kiln is 3-4 degrees. The rotary kiln air-supplying device aims at providing a rotary kiln air-supplying device nozzle which can improve nozzle strength and reduce barrel body load.
Description
Technical field
The utility model relates to revolution drying kiln air-supply arrangement.
Background technology
Carbon fibre material is the new product of developing in recent years.It by the superfines material with gather two kinds of compositions of propionitrile carbon fiber and mix and form; Intensity can be up to 250～560MPa; Advantages such as and general ordinary powder material has only 12MPa usually, and that this dusty material also has is in light weight, hear resistance, fire resistance are good are applicable to various civil construction projects; Be a kind of good structural material, also can be used for aerospace engineering.The carbon fibre material technological process is: 1, broken and preparatory homogenizing; 2, raw material preparation; 3, raw material homogenizing, screening and classification; 4, preheating decomposition, drying; 5, the dusty material grog burns till; 6, dusty material grinding; 7, dusty material packing.
Existing carbon fibre material production is the important accessory device of keeping kiln temperature with the air-supply arrangement of rotary kiln, and one of main element of this device is a nozzle.Nozzle inserts in the kiln and bears 1050 celsius temperatures, under this hot conditions, and easy to crack, the damage of the tube wall of nozzle.Existing nozzle is the center that faces rotary kiln, prevents that flame is directly injected to material, causes the distortion of barrel localized hyperthermia; But because rotary kiln is increasing, nozzle is done longer and longer thereupon, causes the intensity of nozzle to reduce, in addition, the increase of nozzle weight make alternate stress to cylindrical shell to influence water crossing obvious more.
The utility model content
The utility model provides the air-supply arrangement of a kind of carbon fibre material production with rotary kiln, and the purpose of the utility model provides a kind of nozzle that improves nozzle strength, alleviates the cylinder of rotary kiln air-supply arrangement of cylindrical shell load.
For addressing the above problem; The utility model adopts following technical scheme: carbon fibre material production comprises nozzle body (5) with the air-supply arrangement of rotary kiln, and there is first flange (3) top of nozzle body (5); The top of first flange (3) is provided with second flange (4); Nozzle body (5) inwall is provided with reinforcement (2), and the center line in nozzle body (5) exit is provided with discontinuous to be decided wind and pull (1), and discontinuous is decided wind and pulled (1) both sides and connect outlet both sides sidewall; It is the 3-4 degree with the angle of rotary kiln center line that described discontinuous is decided aerofoil (1).Preferably: it is 4.5 degree with the angle of rotary kiln center line that described discontinuous is decided aerofoil (1).
The carbon fibre material production of the utility model is with the air-supply arrangement of rotary kiln, adopt discontinuous to decide aerofoil and can guarantee flame at length range more than 8 meters, all the time in the central area of rotary kiln, but and constant wind to and flame profile; Reinforcement has delayed the expansion of the crack due to thermal stress of nozzle; Double-layer flange reduces the influence of alternate stress to cylindrical shell all in the outside of rotary kiln body; Alleviated the working strength of bolt.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: discontinuous is decided wind and is pulled (1), reinforcement (2), first flange (3), second flange (4), nozzle body (5).
The specific embodiment
As shown in Figure 1; Carbon fibre material production comprises nozzle body (5) with the air-supply arrangement of rotary kiln, and there is first flange (3) top of nozzle body (5); The top of first flange (3) is provided with second flange (4); Nozzle body (5) inwall is provided with reinforcement (2), and the center line in nozzle body (5) exit is provided with discontinuous to be decided wind and pull (1), and discontinuous is decided wind and pulled (1) both sides and connect outlet both sides sidewall; It is 4.5 degree with the angle of rotary kiln center line that described discontinuous is decided aerofoil (1).
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
Claims (2)
1. carbon fibre material production is with the air-supply arrangement of rotary kiln; Comprise nozzle body (5); There is first flange (3) top of nozzle body (5), it is characterized in that: the top of first flange (3) is provided with second flange (4), and nozzle body (5) inwall is provided with reinforcement (2); Center line in nozzle body (5) exit is provided with discontinuous to be decided wind and pulls (1), and discontinuous is decided wind and pulled (1) both sides and connect outlet both sides sidewall; It is the 3-4 degree with the angle (α) of rotary kiln center line that described discontinuous is decided aerofoil (1).
2. carbon fibre material production is characterized in that with the air-supply arrangement of rotary kiln according to claim 1, and it is 4.5 degree with the angle (α) of rotary kiln center line that described discontinuous is decided aerofoil (1).
