Abstract
A kind of sleeve chimney only shakes device, at least three including being circumferentially uniformly fixed on ring beam lateral surface only shake device, the device that only shakes includes limiting device, two wall-connecting pieces of herringbone structure are connect, formed with limiting device, one end of the wall-connecting piece is fixed on the medial surface of outer tube wall, and the other end is connect with limiting device.The position that the utility model stops rolling end is altered to inner cylinder side by outer cylinder side, shortens torque, avoids torque and cross the high disadvantage of long material oneself requirement.
Description
Technical field
The utility model belongs to mechanical structure more particularly to a kind of sleeve chimney only shakes structure.
Background technique
It is provided according to the anticorrosion chapters and sections of " Code for design of chimneys " (GB50051-2013): for wet flue gas operating condition item
Part, it is proposed that using telescopic non-corrosive metal (NCM) liner, telescopic lightweight anti-corrosion brick lining or glass reinforced plastic inner cylinder, it is not recommended that choose monotubular
Formula chimney structure form；Therefore domestic desulfurization Wet chimney anti-corrosion transformation is essentially sleeve-type chimney, and sleeve-type chimney can be according to not
With geographical location be arranged it is different only shake device, the setting for only shaking device is related to the stability and outer cylinder of inner shaft system
Safety, traditional only rolling device stability is poor, and to outer cylindrical at certain damage, to bring a series of problem.
Traditional only rolling device is set as at 4 points and stops rolling form, and only shakes end close to outer cylinder；The only rolling device of 4 forms
When stress is shaken the device that works can only there are two, and the time it is long can carry out impact wear to outer cylinder long afterwards, cause final
It can not play the role of only rolling, then need to verify if transformation chimney and only shake on whether the impact force of outer cylinder influences outer tube structure peace
Entirely.The invention is intended to only to shake device and increases at 7 points, and only shakes end close to inner cylinder；It not only avoids damage outer cylinder and enhances
Only shake effect.
Utility model content
The utility model, which provides a kind of multiple spot, to be stopped the sleeve chimney shaken and only shakes structure, to solve of the existing technology ask
Topic.
The utility model uses following technical scheme:
A kind of sleeve chimney only shakes structure, is uniformly fixed on at least three of ring beam lateral surface including circumferential and only shakes device,
The device that only shakes includes limiting device, and two wall-connecting pieces of herringbone structure are connect, formed with limiting device, the even wall
One end of part is fixed on the medial surface of outer tube wall, and the other end is connect with limiting device.
The limiting device includes the only rolling head being connected with inner cylinder, only shakes both sides of head setting limit buttress, and wall-connecting piece connects
It connects on limit buttress.
The wall-connecting piece is rectangular tube or round tube.
It is described only shake structure include 7 of ring beam lateral surface are evenly distributed on only to shake device, and with only shake what device was connect
14 wall-connecting pieces.
The utility model has the beneficial effects that
(1): will only shake point quantity becomes at 7 points from 4 points and can uniformly share on outer cylinder after stress；
(2): the position for only shaking end is altered to inner cylinder side by outer cylinder side, shortens torque, avoids torque and crosses long material certainly
The demanding disadvantage of body；
(3): the fixing end of two herringbone wall-connecting pieces and platform on the outside of force side can be more in the form of pressure by power
Point is transmitted to outer cylinder, and it is easy to damage to be unlikely to the fracture resistence force that Conventional limit angle steel is received；
(4): can be substantially reduced because only rolling damages or only shake the probability of damage to outer cylinder, be accumulated to ensuring that construction quality has
The meaning of pole.
Detailed description of the invention
Fig. 1 is that tradition only shakes structure.
Fig. 2 is the only rolling structure of the utility model.
Fig. 3 is the structure of limiting device.
Fig. 4 is wall-connecting piece and outer cylinder connection schematic diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The utility model provides a kind of sleeve chimney and only shakes structure, and should only shake structure include multiple only shaking device, Duo Gezhi
Device is shaken circumferentially uniformly to be fixed on the lateral surface of ring beam 3.
Each device that only shakes includes limiting device 2 and two wall-connecting pieces 4, and limiting device 2 is fixed on the lateral surface of ring beam 3
On, one end of wall-connecting piece 4 is fixed on the medial surface of outer tube wall 1, the other end contacts with limiting device 2, by limiting device 2 into
Row limit, the medial surface that two wall-connecting pieces 4 connecting with the same limiting device 2 are connected in outer tube wall 1 form herringbone structure, increase
Add its stability.
Rectangular tube or round tube may be selected in wall-connecting piece 4.
As shown in figure 3, limiting device 2 includes the only rolling head 6 for being embedded into ring beam 3, the longitudinal limit of 6 two sides of head setting is only shaken
Buttress 7, two wall-connecting piece one end are connected on limit buttress 7, and the other end is connect by cockermegs with outer tube wall, keeps power equal
Even is transmitted to outer cylinder.
As shown in figure 4,4 other end of wall-connecting piece is connected on embedded part 8, embedded part 8 is fixed on outer tube inner wall, and on embedded part 8
Fixation is supported fixed gusset 9 to wall-connecting piece 4.
In embodiment as shown in Figure 2, only shake structure include be evenly distributed on 7 of 3 lateral surface of ring beam only shake device and
With 14 wall-connecting pieces that only rolling device is connect.7 be evenly arranged only shake device, make limiting device using existing ring beam,
And to ensure the firm of limiting device, two herringbone wall-connecting pieces 4 are set in limiting device two sides, make only to shake device when inner cylinder stress
A minimum of 6 points can vertically play position-limiting action, be easily damaged rather than angle steel of traditional limit on outer cylinder, can be with
By being fixed on ring beam as the wall-connecting piece for only shaking end, it is transmitted on outer cylinder by the embedded part of ring beam, platform, design in this way makes
The stress of inner cylinder can be distributed on outer cylinder with multiple spot, and reduction is damaged caused by outer cylinder；And the connection of wall-connecting piece and only rolling device
End, which is used as, only shakes endpoint, so that the shortcomings that only shaking endpoint close to inner cylinder, avoiding torque too far, so that external force is in most reasonable model
It is passed in enclosing；Influence of the unbalance stress to outer cylinder is avoided in this way.
In the description of this specification, particular features, structures, materials, or characteristics can be real in any one or more
Applying can be combined in any suitable manner in example or example.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art the variation that can readily occur in or is replaced in the range of the utility model discloses
It changes, should all cover within the protection scope of the present utility model.
