Description
Technical field
This utility model relates to a kind of soot blower and the sealing device on boiler flue.
Background technology
Convection bank, air preheater etc. on heating furnace in power industry, boiler, be typically all and use soot blower to it
Surface carries out ash disposal, remove the gred operation, and then can reduce the temperature of smoke evacuation, improves heating furnace, the thermal efficiency of boiler, reaches
To reducing energy consumption, the purpose of energy-saving and emission-reduction.Soot blower is provided with blowing pipe, and blowing pipe stretches into burner hearth and its inside is carried out ash disposal,
Being provided with sealing ring at the thorax mouth of burner hearth, original sealing ring is negative-pressure type, simple in construction, and seal clearance is excessive, it is impossible to suitable
Answering the environment of the frequent malleation of furnace outlet, cause burner hearth fire inleakage, thermal loss thoroughly to increase, flying dust leaks outside increase, soot blowing
Device internal and external casing is by dirty and abrasion.
Utility model content
In order to solve, existing seal ring structure is simple, sealing is poor, and to the problem making burner hearth fire thoroughly, leak out, this practicality is new
Type provides a kind of new sealing ring, and specifically technical scheme is:
A kind of soot blowing negative pressure self-sealed sealing ring of wall case, described sealing ring includes base, rotating ring and ring cowling, and described rotating ring is pacified
Being contained between base and ring cowling, rotating ring is formed by multiple pawl combination, and the root of described ratchet pieces together the ring body of rotating ring, institute
Stating ratchet head is spring body, and adjacent two ratchet junctions are provided with suitable lobe and recess；Described base is two semi-rings pair
The structure closed, on described base, radial direction is provided with the through hole accommodating described spring body；Described base and ring cowling are provided with position pair
The bolt hole answered.
This utility model sealing ring can remove flue dust, corrosion, coal tar and foreign material on blowing pipe automatically, can be effectively
Extend the service life of soot blowing gun barrel, moreover it is possible to effectively stoping the leakage of inner flue gas of the stove ashes, keep the scene intact hygienic conditions, subtracts
Few dust pollutes, and improves the cleaning of boiler.This sealing ring uses Redundancy Design, compact conformation, and installation and repairing is convenient, safety
Reliably, can move about therewith with degree of disturbing produced by the rotation of soot blowing outer tube and hug soot blowing outer tube all the time during work, will not produce
Raw gap, good leak tightness.
Accompanying drawing explanation
Fig. 1 is this utility model exploded view；
Fig. 2 is understructure figure；
Fig. 3 is the structure chart of ratchet；
Fig. 4 is the scheme of installation of rotating ring；
Fig. 5 is that this utility model uses state diagram.
Base 1 in figure, bolt hole 11, through hole 12, rotating ring 2, the root 21 of ratchet, the head 22 of ratchet, lobe 23, recessed
Mouth 24, ring cowling 3.
Detailed description of the invention
Illustrating this utility model below in conjunction with the accompanying drawings, a kind of soot blowing negative pressure wall case as Figure 1-5 is self-sealed close
Seal ring, it includes that base 1, rotating ring 2 and ring cowling 3, described rotating ring 2 are arranged between base 1 and ring cowling 3, rotating ring 2
Being formed by multiple pawl combination, the root 21 of described ratchet pieces together the ring body of rotating ring 2, and the head 22 of described ratchet is bullet
Spring body, adjacent two ratchet junctions are provided with suitable lobe 23 or recess 24；Described base 1 is the knot that two semi-rings are involutory
Structure, on base 1, radial direction is provided with the through hole 12 accommodating described spring body；Described base and ring cowling are provided with the bolt hole of correspondence
11。
Installation process of the present utility model:
1) one of them semi-ring of base is fixed on thorax mouth；
2) ratchet on each ring block of composition rotating ring is put into the semi-ring fixed one by one, and in another semi-ring, with
Time lobe is inserted recess；
3) another semi-ring of base is combined fixing with previous semi-ring, simultaneously can be by complete for rotating ring split；
4) with bolt, ring cowling is fixed with base,.
Work process of the present utility model:
When boiler plant works, producing a large amount of flue dust in burner hearth, the blowing pipe of soot blower stretches into burner hearth, after soot blower starts, respectively
Ratchet does irregular upper and lower strained movements with being rotated on outer tube of soot blower outer tube under the effect of spring body, is formed relatively
In the sealing of soot blower outer pipe surface, thus flying dust is stoped to leak.
The ratchet of composition rotating ring divides actively ratchet and by pawl two kinds, Fig. 1 and Fig. 4 indicates 4 actively ratchets, 4
One example of the rotating ring pieced together by pawl.As it can be seen, spring body top is additionally provided with screw, this screw can be used to adjust
The holding tube pressure of joint ratchet, can be used in and more renew outer tube or be contained in above the old outer tube of soot blower used after a while, with this
Regulate sealing.
Described rotating ring is not limited to shown in accompanying drawing be made up of eight ratchets, as long as each ratchet of composition rotating ring can produce radially
Vibration so that blowing pipe surface can be impacted bottom ratchet and realize deashing and i.e. can embody the creation thought of the present invention.Based on upper
Stating thought, the rotating ring that at least four pawl combination becomes can realize goal of the invention.
Owing to each ratchet split designs, each blowing pipe is impacted deashing, even if so the part ratchet that is in operation loses vigor
Can not use whole sealing ring complete failure, but the ratchet of at least half quantity can guarantee that ash-removal effect in work.
Sealing ring provided by the utility model can remove flue dust, corrosion, coal tar and foreign material on blowing pipe automatically, can
Effectively to extend the service life of soot blowing gun barrel, moreover it is possible to effectively stop the leakage of inner flue gas of the stove ashes.This sealing ring uses
Redundancy Design, compact conformation, installation and repairing is convenient, safe and reliable, can disturb during work produced by the rotation of soot blowing outer tube
Degree and travelling therewith and hug soot blowing outer tube all the time, gap will not be produced, good leak tightness, and will not to soot blower other zero
Component working produces any impact, allows 50% ratchet pressure failure, use replaceable standby in the case of sealing effectiveness does not subtracts
Part formula designs, and reduces cost and pays, improves economy.Significant sealing affection, substantially improves production on-site environment, reduces
Burner hearth leaks out, and improves boiler efficiency.
