Description
Technical field
This utility model is related to a kind of sealing structure, and in particular to granule heat exchanger steam sootblower sealing structure
Background technology
Most widely used and it is most useful that steam sootblower in slag-blowing equipmemt.The operation principle of steam sootblower is：Interior
Pipe (steam supply pipe) is in the inside of outer tube (soot blowing gun barrel) and both are coaxial, in soot blower running, inner tube remains stationary
Motionless and supply steam to outer tube, outer tube while rotation at the uniform velocity advances or retreats, the position different so as to purge heating surface.
Due to there is complex relative motion between inner and outer pipes, the impact of hot environment is added, inner tube or outer tube in running
Often there are the failures such as eccentric, radial and axial displacement, then steam leakage often occurs in the sealing structure between inner and outer pipes
Problem, what this was serious have impact on the safety and economic operation of power plant.Conventional seals structure is made up of grommet, airtight and watertight padding and gland,
As outer tube is rotary extension motion so that the gap between airtight and watertight padding and inner and outer pipes constantly increases with the abrasion of airtight and watertight padding
Greatly, so as to cause sealing structure fail.The leakage of steam can cause soot blowing effect to be deteriorated, device damage, or even entail dangers to operation
The safety of personnel.
Utility model content
In order to solve the sealing problem between steam sootblower inner and outer pipes, this utility model provides granule heat exchanger steam and blows
Grey device sealing structure.
The technical scheme adopted by this utility model is：Granule heat exchanger steam sootblower sealing structure, it is characterised in that：
The sealing structure constitute by grommet, black box, airtight and watertight padding and from gland, and the black box is by little sealing ring, big
Sealing ring, matrix sealing member and convex sealing member composition, the matrix sealing member and convex sealing member cooperate and constitute two
Closed chamber, the wherein closed chamber near outer tube wall side are equipped with big sealing ring, and the closed chamber near outer wall of inner tube side is equipped with
Little sealing ring, described two sealing rings are all that gap coordinates with tube wall is contacted.
Described be made up of from gland movable end cover, spring, supported flange and bolt, the screw on the movable end cover is
Unthreaded hole so that movable end cover can be moved axially along pipe, the screw on the supported flange are screwed hole, and fitted bolt is to entirely close
Seal structure applies pressure.
The spring is located between movable end cover and supported flange, and is enclosed within bolt.
At least provided with 4 screwed holes on the supported flange, in the light hole number on the movable end cover and supported flange
Screw thread hole number identical, and unthreaded hole and screwed hole correspond.
This utility model has advantages below：
1. two sealing ring both sides are subject to the pressure from sealing member all the time, it is ensured that the black box is transported in soot blower
Good sealing effectiveness is always maintained in row work.Closed chamber leaves certain activity space simultaneously, it is allowed to which inner and outer tubes are produced
, there is such failure so as to avoid soot blower in the certain eccentric and radial displacement of life.
2. spring is subject to the pressure of supported flange and is in compressive state, the elastic force of spring act on movable end cover so as to
Pressure is applied to whole sealing structure.When the gap between airtight and watertight padding and inner and outer pipes becomes big with abrasion, due to movable end
Lid can be moved axially along pipe, then can inwardly extrude a certain distance under the elastic force effect of spring, so that airtight and watertight padding
Abrasion is compensated.Sealing effectiveness had so both been ensure that, the usage cycles of airtight and watertight padding had been extended again, the material resources of maintenance had been saved
And financial resources.

Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is further described.
As shown in figure 1, granule heat exchanger steam sootblower sealing structure, this sealing structure be installed on outer tube 1 and inner tube 2 it
Between, constitute by grommet 3, black box 13, airtight and watertight padding 8 and from gland 14.
Black box 13 is made up of little sealing ring 4, big sealing ring 5, matrix sealing member 6 and convex sealing member 7, and matrix is sealed
Part 6 and convex sealing member 7 cooperate and constitute two closed chambers, and wherein the closed chamber near 1 inwall side of outer tube is equipped with close greatly
Seal ring 5, the closed chamber near 2 outer wall side of inner tube are equipped with little sealing ring 4.Two closed chambers all leave certain activity space,
Allow inner tube 2 and outer tube 1 to produce certain eccentric and radial displacement, eccentric, radial and axial position occurs so as to avoid soot blower
The failures such as shifting.Little sealing ring 4 and big sealing ring 5 are all that gap coordinates with tube wall is contacted so that little sealing ring 4 and big sealing ring 5
Both can move axially along pipe, can rotate in closed chamber space again, can so ensure that outer tube 1 was being made when rotary extension is moved not
Impacted.Two sealing rings are also sealing surface with the contact surface of sealing member, as sealing ring both sides are subject to all the time from sealing member
Pressure, therefore the sealing surface be constantly in good sealing effectiveness.
It is made up of from gland 14 movable end cover 9, spring 10, supported flange 11 and bolt 12, the spiral shell on movable end cover 9
Hole is unthreaded hole so that movable end cover 9 can be moved axially along pipe, the screw on supported flange 11 be screwed hole, fitted bolt 12 pairs
Whole sealing structure applies pressure.Spring 10 is subject to the pressure of supported flange and is in compressive state, and the elastic force of spring 10 makes work
Moved end lid 9 remains the pressure to airtight and watertight padding 8, accordingly even when airtight and watertight padding 8 has a certain degree of abrasion obtain
Compensation.
In sum, the sealing structure good sealing effect, can avoid steam sootblower that steam leakage occurs, and improve soot blowing effect
Rate.Simultaneously equipment is not susceptible to failure, improves the reliability and service life of equipment, extends maintenance cycle, save material resources and
Financial resources.
