Abstract
The utility model discloses a corrugated pipe sealing device, which is characterized in that a corrugated pipe is arranged at the outside of a vibration beating rod. The corrugated pipe sealing device of the utility model spurns the traditional idea of the stuffing box sealing, which uses the elasticity of the corrugated pipe to seal a mechanical vibration beating dust removing device.
Description
Technical field:
The utility model relates to mechanical technical field, specifically a kind of bellow seal.
Background technique:
Exhaust heat boiler is to utilize waste heat contained in the industrial waste gas to convert it into a kind of energy-saving equipment of steam.Usually contain a large amount of dust in the industrial waste gas, when it is deposited on the boiler heat-exchanger surface, just will influence heat exchange efficiency.So, continuous deashing in boiler running process, mechanical vibrator is exactly a kind of ash-clearing technology commonly used.Force transfer element-the vibrating rod of mechanical vibrator is in a kind of harmonic motion of reciprocal decay at work.Boiler body and atmosphere environment have bigger pressure reduction usually.At this moment just need between vibrating rod and body of heater, seal arrangement be installed, working medium in the boiler and atmosphere are isolated.What traditional sealing was adopted is the packing box seal technology, shown in figure ().When Gland 8 compressed, filler 9 just produced certain specific pressure to vibrating rod 1, this than pressure energy when the vibrating rod to-and-fro motion, reduce or the blocking-up stove in the mutual seepage of working medium (industrial waste gas) and atmosphere, to keep the stable of inner operating.But the packing box seal technology also exists obvious defects: (1) sealing unreliable (2) filler (3) easy to wear maintenance workload big (4) damage vibrating rod.For many years, people have spent a large amount of energy and have improved on filler material and structural type, attempt to break through, but above-mentioned defective ubiquity still.
Summary of the invention
The purpose of this utility model is to provide a kind of bellow seal, and it can overcome some shortcomings of the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of bellow seal, it mainly comprises vibrating rod, it is characterized in that: described vibrating rod outside is provided with bellows.
The utility model is a kind of bellow seal, and the packing box seal thinking of the utility model abandoning tradition utilizes the elasticity of bellows that the mechanical vibrator deashing device is sealed, because bellows adopts corrosion resistant plate compacting as thin as a wafer to form when implementing, elasticity is fairly good, and after vibrating rod was subjected to hammering, the amplitude of its vibration and damped cycle were all than the mode ideal of packing box seal, and it is simple in structure, better practicability is arranged, and cost of production is low, can be mass-produced, applicability is strong, is easy to promote.
Description of drawings:
Fig. 1 is the existing letter formula sealing device structure formula intention of filling out
Fig. 2 is the utility model structure intention
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model as shown in Figure 2, mainly comprise vibrating rod 1, it is different from prior art and is: described vibrating rod outside is provided with bellows 2, bellows surface is provided with two ripples at least, the bellows two ends are equipped with flange 3, be provided with bolt 4 in the flange, be provided with link 7 between bellows and the flange, be provided with rubber asbestos plate 5 between flange and the bolt.
In the specific implementation, as shown in Figure 2, bellows is fixed on the boiler body 6 by flange and bolt, and the packing box seal thinking of the utility model abandoning tradition utilizes the elasticity of bellows that the mechanical vibrator deashing device is sealed.When rapping apparatus is worked, the to-and-fro motion of vibrating rod is absorbed by the elasticity of bellows, mutual friction mutually no longer takes place with other parts (filler) in vibrating rod, as long as the bellows elastic design is proper, the kinetic energy that vibrating rod consumes herein will be significantly less than packing box seal, and can realize " zero leakage ".
Key technology is the design and fabrication of bellows.Should consider principal elements such as elastic compensating amount, rigidity, fatigue life during bellows design.Bellows can adopt metallic material (stainless steel, aluminium, titanium, Cuprum alloy), rubber, engineering plastics making such as (teflon, vinylon, polyethylene), bellows processing can be adopted technologies such as mold pressing, punching press, car system, because bellows adopts corrosion resistant plate compacting as thin as a wafer to form when implementing, elasticity is fairly good, after vibrating rod is subjected to hammering, the amplitude of its vibration and damped cycle are all than the mode ideal of packing box seal, and the effect of the present removing ash of boiler of final body is relatively good.
