Abstract
The utility model relates to a spiral-barrel leakage-proof device, which is installed on a rotary material receiving barrel of a rotary-barrel type slag-cooling machine and can prevent the slag from leaking. The utility model has the structure that an inlet of the material receiving barrel of the rotary-barrel type slag-cooling machine is welded with a thick steel pipe, and a feed pipe is inclined and inserted into the material receiving barrel from the inner part of the thick steel pipe. A thin steel pipe is welded on an opening of the side of a sealing box, the thin steel pipe is inserted into the thick steel pipe, the feed pipe penetrates through the sealing box and extends out of the thin steel pipe, and the inner wall of the external end of the thick steel pipe is welded with a ring plate. The utility model has the advantages of simple structure and good sealability and can reduce environment pollution and maintain normal operation of a boiler.
Description
The utility model relates to a kind of bulk material leakage device that prevents, and be specially adapted to be installed in being subjected to that cylinder type cold slag machine rotates and prevent on the barrel that slag from leaking outside, be a kind of spiral tube material leak-proof device specifically.
The present feed arrangement of cylinder type cold slag machine because poorly sealed, when slag enter cylinder type cold slag machine be subjected to barrel the time, have a lot of slags to leak outside, surrounding environment is caused very big pollution, increased daily maintenance workload, influenced the normal operation of boiler.
The utility model purpose is to solve the problems of the technologies described above, and proposes a kind of spiral tube material leak-proof device, and what be installed in cylinder type cold slag machine is subjected to barrel import department, prevents that the slag that enters from leaking outside, and the environment that keeps the scene intact normally moves boiler.
The utility model purpose is realized by following technical scheme: this spiral tube material leak-proof device, be subjected to the barrel import to be welded with thick steel pipe at cold slag machine, feed pipe oblique cutting in the thick steel pipe goes into to be subjected to barrel, it is characterized in that on the opening of a seal case side, being welded with fine steel tube, fine steel tube inserts in the thick steel pipe, feed pipe stretches out in fine steel tube by seal case, is welded with ring plate at the thick steel pipe outer end inner wall.
Spiral tube material leak-proof device is welded with flight in ring plate on interior thick steel pipe inwall, forms maze-type structure with ring plate.Prevent that the slag that drains in the thick steel pipe from continuing to leak outside.Be welded on flight, the ring plate of thick steel pipe inwall, in aggregates with thick steel pipe, along with rotated together by barrel.Gapped between one end of flight, ring plate and the fine steel tube outer wall, can not grind sassafras during rotation with the fine steel tube outer wall.
Material is entered by feed pipe and is subjected to barrel, and outside leakage when material is outwards revealed by the fine steel tube endoporus, because casing seals, is just no longer leaked when material level reach a certain height in the casing owing to pile up more; When material from the gap between fine steel tube and the thick steel pipe during to external leakage, because flight is with rotated by barrel, flight promotes material in being subjected to barrel, simultaneously, the maze-type structure that flight, ring plate are formed with thick steel pipe, fine steel tube has prevented that further slag from leaking outside.
The utility model has the advantages that simple in structurely, ingenious, prevent the good airproof performance that material leaks outside, keep the site environment cleaning, reduce environmental pollution, keep boiler normally to move, alleviated the line service amount, do not need additionaling power, energy savings, long service life.
Embodiment of accompanying drawings:
Fig. 1 is a kind of spiral tube material leak-proof device,
This spiral tube material leak-proof device, be subjected to barrel 5 imports to be welded with thick steel pipe 4 at cold slag machine, feed pipe 1 goes into to be subjected to barrel 5 from thick steel pipe 4 interior oblique cuttings, on the opening of seal case 6 sides, be welded with fine steel tube 2, fine steel tube 2 inserts in the thick steel pipe 4, feed pipe 1 stretches out in fine steel tube 2 by seal case 6, is welded with ring plate 7 at thick steel pipe 4 outer end inner walls.Be welded with flight 3 in ring plate 7 on interior thick steel pipe 4 inwalls, form maze-type structure with ring plate 7.Prevent that the slag that drains in the thick steel pipe 4 from continuing to leak outside.Be welded on flight 3, the ring plate 7 of thick steel pipe 4 inwalls, in aggregates with thick steel pipe 4, along with rotated together by barrel 5.Gapped between one end of flight 3, ring plate 7 and fine steel tube 2 outer walls, can not grind sassafras during rotation with the fine steel tube outer wall.
Claims (3)
