Abstract
The utility model relates to a rotary seal device. At present, the traditional labyrinth seal or the asbestos cord and rubber ring seal is adopted to reduce air leakage, however, the effect is not ideal and the air leakage ratio is extremely high, thereby influencing the back flowing and soot cleaning effect of a bag-type dust collector, not ensuring the soot cleaning pressure and wasting large amount of air resources. The seal at rotation part is a difficult problem of the bag-type dust collection in the process of rotating back flowing. The rotary seal device of the utility model comprises a base plate (3) fixed on a sealing cylinder body (1); a cover plate (7) is installed at the other end of the base plate; an annular sealing element (6) is installed between the base plate and the cover plate; a group of adjusting bolts (4) are installed on the base plate, corresponding to the sealing element; a spring (5) or an elastic press sheet (5) is installed between the adjusting bolt and the sealing element. The rotary device is suitable for large-scaled gas ducts in power plants, or the rotating cylinder body sealing field relating thereto.
Description
Technical field:
The utility model relates to the rotary sealing appts in the rotary counter-blowing mechanism of a kind of large compartment location blowback sack cleaner.
Background technology:
Assurance reverse gas cleaning pressure can work normally in order to guarantee sack cleaner rotary counter-blowing deashing.Guarantee the reverse gas cleaning effect, when the fixed cylinder part of sack cleaner rotary counter-blowing mechanism is partly joined with rotary barrel, certain clearance should be arranged, can rotate, take seal approach again, in case leak out.Generally take at present traditional labyrinth sealing or plug asbestos cord and seal with elastometic washer.Leak to reduce air, but all undesirable, air leak rate of air curtain is high, influences sack cleaner reverse gas cleaning effect, does not guarantee deashing pressure, has wasted a large amount of sources of the gas, and the sealing of rotation place is the extremely scabrous problem of of sack cleaner rotary counter-blowing process.
Summary of the invention:
The purpose of this utility model provides a kind ofly can improve effect, energy savings, and can guarantee the blowback rotary sealing appts of the sack cleaner of blowback pressure and ash-removal effect.
The purpose of this utility model is achieved in that
Rotary sealing appts, its composition comprises: be fixed on the seat board on the sealed cylinder, the other end of described seat board is equipped with cover clamp, between described seat board and the described cover clamp lip ring is housed, one group of adjusting bolt corresponding to described seal is housed on the described seat board, between described adjusting bolt and the described seal spring or elastic pressuring plate is housed.
Described rotary sealing appts, described lip ring section has spill or dovetail groove, and the ejector pin to described lip ring is housed on the described seat board.
Described rotary sealing appts, described seat board and cover plate are the two-opening type structure, and diameter is between φ 200mm～φ 2000mm.
This technical scheme has following beneficial effect:
1. when working, seal 6 is done flexible fine motion (on diametric(al)) with the rotation of cylindrical shell, but owing to the effect of holddown spring 5 is pressed on the rotating cylinder 8 seal 6 all the time, slide and rotate the effect of really playing sealing in no gap.Seal 6 is wear-resisting, exotic material, because the rotating speed of rotary counter-blowing mechanism is lower, so it is lower to wear and tear, it has improved the tightness of deduster rotary counter-blowing system rotating part, the operating efficiency of deduster rotary counter-blowing deashing is greatly improved, save a large amount of sources of the gas, guaranteed reverse gas cleaning pressure, improved the reverse gas cleaning effect.
2. the adjusting bolt regulating spring pressure of installing by the side guarantees sealing effectiveness.
3. carry out the overall structure location by bolt, removable performance is good, and is easy to adjust.Seat board and cover plate are the two-opening type structure, and structural behaviour is good.
4. the seal inner surface has the dovetail groove or the rectangular channel of indent, plays to reduce friction and sealing function.
5. there is the blind hole groove side, plays the positioning and guiding effect under the effect of alignment pin.

The specific embodiment:
Embodiment 1:
Rotary sealing appts, its composition comprises: be fixed on the seat board 3 on the sealed cylinder 1, the other end of described seat board is equipped with cover clamp 7, between described seat board and the described cover clamp lip ring 6 is housed, described rotary sealing appts, one group of adjusting bolt 4 corresponding to described seal is housed on the described seat board, spring 5 or elastic pressuring plate 5 are housed between described adjusting bolt and the described seal.
Embodiment 2:
Embodiment 1 described rotary sealing appts is equipped with the ejector pin 2 of described lip ring on the described seat board, have corresponding spill or dovetail groove 11 on described lip ring section.Under the effect of alignment pin, play the positioning and guiding effect.
Described seat board and cover plate can adopt the two-opening type structure, and diameter sealing property between φ 200mm～φ 2000mm is better.
With several ring-like seals 6, be set in the groove of seat board 3 and pressing plate 7 compositions during installation, by alignment pin 2 positioning and guidings, adjust bolt 4 spring 5 is pressed in the groove, top tight sealing spare 6 closely is pressed on the rotating cylinder 8 seal.Ring has seal groove 9 in the seal, and sealing ring 10 wherein is housed.
Claims (3)
