Abstract
The invention relates to a roller air seal device used for a carton fiber precursor and a carbon filament. The roller air seal device used for the carton fiber precursor and the carbon filament comprises a steam extending chamber middle section and two steam extending chamber end sections at the two ends of the steam extending chamber middle section, wherein the steam extending chamber middle section and the two steam extending chamber end sections are sealed through two rows of exhaust sealing cavities respectively; a plurality of steam supply pipes are installed in the steam extending chamber middle section; the two steam extending chamber end sections are internally provided with air seal rollers used for air seal; the air seal rollers and the two steam extending chamber end sections are in sealed connection together. Compared with existing frequency-used air seal devices, the roller air seal device used for the carton fiber precursor and the carbon filament has the advantages of being good in air seal effect, small in occupied area and low in cost.
Description
Technical field
The present invention relates to a kind of air seal set, particularly relate to and a kind ofly can promote quality and save steam consumption, reduce the carbon fibre precursor of occupied ground length and the running roller air seal set that carbon filament is used.
Background technique
As shown in Figure 1, labyrinth seal (Labyrinth Seal, i.e. ring packing) is macrophyll wheel mechanical, as the equipment of minimizing leakage rate common in steam turbine and high-pressure compressor.Yet for the turbomachinery of high parameter, sealing gland leakage flow is easily brought out flow-induced vibration, oneself becomes one of key factor affecting shafting stability, and sealing gland tooth 2 is installed in labyrinth seal 1 in Fig. 1, and this is current modal labyrinth seal.
In addition, when labyrinth seal is arranged on the both sides of steam extending chamber, because labyrinth seal is when the good sealing gland effect of needs, the length that labyrinth seal need to be installed is long, and the place taking is larger.
In order to solve above these problems, propose honeycomb sealing gland (Honeycomb Gas Seal) abroad, as shown in Figure 2, transform annular chamber 3 as honeycomb shape, by increasing rubbing surface, strengthen leakage flow energy and consume, thereby reduce leakage rate, also strengthen stability.Yet honeycomb sealing gland processing difficulties, involves great expense, in industrial quarters, do not obtain extensively should so far.
Therefore, when large-scale steam suppling tube needs sealing gland, the above-mentioned labyrinth seal of mentioning and honeycomb sealing gland are not optimal selections, need a kind of new air seal method to solve sealing gland weak effect, and cost is high, the air seal set that occupied ground area is large.
Summary of the invention
For the problems referred to above, main purpose of the present invention is to provide a kind of and can promotes quality and save steam consumption, reduce the carbon fibre precursor of occupied ground length and the running roller air seal set that carbon filament is used.
The present invention solves above-mentioned technical problem by following technical proposals: the running roller air seal set that a kind of carbon fibre precursor and carbon filament are used, the steam extending chamber two ends section that comprises steam extending chamber intermediate section and steam extending chamber intermediate section two ends, steam extending chamber intermediate section and steam extending chamber two ends section all adopt two exhaust envelope cavity sealings, a plural number steam suppling tube is installed in steam extending chamber intermediate section, sealing gland running roller for sealing gland is all installed in steam extending chamber two ends section, and described sealing gland running roller and steam extending chamber two ends section are sealed connected together.
In specific embodiments of the invention: described sealing gland cavity is vertical with steam suppling tube.
In specific embodiments of the invention: described sealing gland cavity surrounds sealing gland running roller near the part of sealing gland running roller.
In specific embodiments of the invention: described sealing gland cavity adopts flexible connection in the part near sealing gland running roller and sealing gland running roller.
In specific embodiments of the invention: be provided with sealing baffle between described sealing gland running roller and steam extending chamber.
In specific embodiments of the invention: described steam extending chamber two ends section is " L " type.
Positive progressive effect of the present invention is: the running roller air seal set that carbon fibre precursor provided by the invention and carbon filament are used has the following advantages: compare with current conventional air seal set, sealing gland of the present invention is effective, and occupied ground area is little, and cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of current conventional labyrinth seal.
Fig. 2 is the structural representation of current conventional honeycomb sealing gland.
Fig. 3 is the structural representation of the form sealing gland steam extending chamber of current conventional employing labyrinth seal.
Fig. 4 is the structural representation of the form sealing gland steam extending chamber of the running roller sealing gland that adopts of the present invention.
Embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present invention, to describe technological scheme of the present invention in detail.
Fig. 3 is the structural representation of the form sealing gland steam extending chamber of current conventional employing labyrinth seal, Fig. 4 is the structural representation of the form sealing gland steam extending chamber of the running roller sealing gland that adopts of the present invention, and in Fig. 3 and Fig. 4, the direction of arrow all represents the traffic direction of carbon fiber.As shown in Figure 3-4: the steam extending chamber two ends section 6 that the present invention includes steam extending chamber intermediate section 4 and steam extending chamber intermediate section 4 two ends, steam extending chamber intermediate section 4 and steam extending chamber two ends section 6 all adopt two exhaust envelope cavity 9 sealings, a plural number steam suppling tube 5 is installed in steam extending chamber intermediate section 4, the interior sealing gland running roller 7 being all provided with for sealing gland of steam extending chamber two ends section 6, described sealing gland running roller 7 and steam extending chamber two ends section 6 are sealed connected together.
Sealing gland cavity 9 is vertical with steam suppling tube 5, and sealing gland cavity 6 surrounds sealing gland running roller 7 near the part of sealing gland running roller 7, and sealing gland cavity 9 adopts flexible connection in the part near sealing gland running roller 7 and sealing gland running roller 9.Between sealing gland running roller 7 and steam extending chamber 6, be provided with sealing baffle 8, play the effect of inside cavity and outside atmosphere isolation.In Fig. 4, between sealing gland running roller 7 and steam extending chamber 6, be provided with sealing baffle 8
Steam extending chamber two ends section 6 is " L " type, the direction of the expression carbon fiber of arrow operation in Fig. 4, because of the open to atmosphere basal area difference great disparity of steam extending chamber, supplying with under the condition that the pressure of steam and flow are identical, P2 is significantly greater than P1, T2 is greater than T1, therefore can promote quality and save steam consumption.
Because running roller sealing gland length relative extent shortens, therefore can reduce occupied ground length.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
