Abstract
The utility model relates to a seal device between a pellet firing machine furnace cover and a trolley, and belongs to the technical field of pellet firing equipment. The seal device comprises a bracket 1, a fixing clamp 2, soft seal cloth 3, a pin shaft 4, a spring 5, a pressing plate 6, a seal plate 7, a positioning shaft 8, a steel plate 9 and an oil nozzle 10. The fixing clamp is fixed on the bracket 1 through a bolt, the pin shaft 4 and the spring 5 are mounted in a pin hole in the fixing clamp 2, the seal plate 7 is attached onto the bracket 1, the oil nozzle 10 is mounted in the seal plate 7, the upper portion of the soft seal cloth 3 penetrates through the steel plate 9 through a bolt to be connected with the bracket 1, and the lower portion penetrates through the pressing plate 6 through a bolt to be connected with the seal plate 7. According to the seal device between the pellet firing machine furnace cover and the trolley, the soft seal cloth 3 is used for sealing space between the bracket 1 and the seal plate 7, and the positioning shaft 8 is welded on the bracket 1 for guiding the up-down motion of the seal plate 7 and limiting the trolley operation direction. The seal device has the advantages of reasonable structure, good seal property, long service life, convenience in mounting and dismounting and the like.
Description
Technical field
The utility model belongs to the pellet roasting equipment technical field, and the sealing device between a kind of pellet firing machine bonnet and chassis particularly is provided, and is used for reducing leaking out between bonnet internal atmosphere and extraneous air, thereby reduces the loss of heat or energy.
Background technology
The burning machine bonnet that uses at present and the sealing device between the chassis, because the reason of design and manufacture view, in actual use, it is more to leak out, and mainly contains following shortcoming and defect:
1. because carriage is Welding Structure, and the friction surface flatness between carriage and sealing plate is not high, in use, the gap will inevitably occur between carriage and sealing plate, form the passage that leaks out; And carriage in use for some time, has thermal deformation, also can strengthen the gap at this place.
2. in the hermetically-sealed construction that uses at present, owing to consider fluctuating and thermal expansion of sealing plate, all can be provided with the gap between adjacent two sealing plates; And owing to will avoid the operational relation of friction plate on sealing plate and the chassis, all to very large guiding chamfering be set at the two ends of sealing plate.Adjacent seals sheet separation and guiding chamfering have also formed the larger passage that leaks out.
Summary of the invention
The purpose of this utility model is to provide the sealing device between a kind of pellet firing machine bonnet and chassis, and by reasonable hermetically-sealed construction pattern, minimizing is leaked out, and then improves the utilization rate of heat and wind.
The utility model comprises carriage 1, stationary fixture 2, flexible sealing cloth 3, bearing pin 4, spring 5, pressing plate 6, sealing plate 7, locating shaft 8, steel plate 9, oil nozzle 10.Stationary fixture 2 is bolted on the carriage 1, and bearing pin 4 and spring 5 are installed in the pin-and-hole on the stationary fixture 2; By the effect of spring 5, sealing plate 7 is attached on the carriage 1, and oil nozzle 10 is on sealing plate 7; Flexible sealing cloth 3 tops are linked together by steel plate 9 and carriage 1 with bolt, and the bottom is linked together by pressing plate 6 and sealing plate 7 with bolt; Utilize the gap between flexible sealing cloth 3 seal brackets 1 and the sealing plate 7; Locating shaft 8 is welded on the carriage 1, is used for the spacing of the guiding that moves up and down of sealing plate 7 and chassis traffic direction.
Carriage 1 is Welding Structure, is water-cooling structure near a side of bonnet inside, is linked together with bolt and bonnet and support, and its effect is for position and the direction of guaranteeing sealing plate 7.
Flexible sealing cloth 3 adopts flexible materials to make, and according to bonnet different temperature everywhere, adopts different materials, and different-thickness is adjustable, and assurance is not leaked out.Adjacent flexible sealing cloth 3 mutually overlaps and is coupled to each other, easy installation and removal, and good sealing effect, and avoided wind to reveal from the gap between carriage 1 and the sealing plate 7.
Sealing plate 7 adopts steel plate to make, and is provided with oil groove and oil nozzle 10 at each sealing plate 7.The time regularly in oil groove, carry lubricant grease by oil nozzle 10 in normal operation, be used for the lubrication and seal plate and friction plate above the chassis, reduce friction, play simultaneously the effect of sealing.Form labyrinth seal by bridging arrangement between the adjacent seals plate.Sealing plate 7 is by being welded on locating shaft 8 displacements of restriction sealing device on the chassis traffic direction on the carriage 1.Lower in working order, sealing plate forms slideway friction with the chassis friction plate under the effect of self gravitation, play sealing function.
The utlity model has the characteristics such as rational in infrastructure, good seal performance, long service life, easy installation and removal, for the working service of pellet firing machine provides reliable equipment to guarantee.
