It changes more frequently, traditional air preheater bobbin carriage tube-to-tube sheet connection uses welded seal form, and sealing effect is bad.
Utility model content
The utility model provides a kind of sealing regenerative air heater, including cabinet and air preheater pipe, on cabinet two it is opposite
Aperture is symmetrically arranged on side, air preheater pipe is arranged in the horizontal direction, and is installed in the aperture, further includes sealing
Pad, gasket is socketed on the air preheater tube end, in the gasket lateral surface cabinet corresponding with the aperture
Wall connection, the gasket includes ceramic washer, the flexible gaskets being set on the ceramic washer inner wall, and along the pottery
Several seal bosses of the circumferentially-spaced distribution of porcelain washer, each seal boss are set along the axially extending of the flexible gaskets
It sets, and successively successively decreases setting along far from end direction height, the cabinet is recessed corresponding to several are provided on aperture inner wall
Slot, the groove are corresponded and are equipped with the seal boss.
Preferably, locating piece is connected on the outer wall of the ceramic washer end, outside the locating piece and the seal boss
Side connection.
Preferably, it is provided with screw thread on outer wall of the ceramic washer far from described cabinet one end, the ceramic washer is remote
From the nut for being equipped with and being threadedly engaged on described cabinet one end, the nut is located at locating piece far from described cabinet one end.
The utility model, which has the advantage that, is sealed air preheater pipe using flexible gaskets, while utilizing seal boss
Cooperation sealing is carried out with the concave ring on cabinet, to realize effectively sealing.
Other features and advantages of the utility model will illustrate in the following description, also, partly from specification
In become apparent, or understood and implementing the utility model.The purpose of this utility model and other advantages can pass through
Structure specifically indicated in the written description, claims, and drawings is achieved and obtained.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.
In the accompanying drawings:
Fig. 1 is the overall structure figure of air preheater.
Fig. 2 is the schematic diagram of the seal assembly of air preheater.
Fig. 3 is the partial schematic diagram of the seal assembly of air preheater.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figure 1-3, the utility model embodiment provides a kind of sealing regenerative air heater, including cabinet 1 and sky
Pre- device pipe 2 is symmetrically arranged with aperture on two opposite flanks on cabinet 1, and air preheater pipe 2 is arranged in the horizontal direction, and is installed
In in the aperture, which is characterized in that further include gasket 3, gasket 3 is socketed on 2 end of air preheater pipe, described close
3 lateral surface of packing, 1 inner wall of the cabinet connection corresponding with the aperture, the gasket 3 includes ceramic washer 31, is set to
Flexible gaskets 32 on 31 inner wall of ceramic washer, and several sealings along the circumferentially-spaced distribution of the ceramic washer 31
Boss 33, each seal boss 33 along the flexible gaskets 32 axially extending setting, and along far from end direction height
Successively successively decrease setting, the cabinet 1, which corresponds on aperture inner wall, is provided with several grooves, the groove and the seal boss
33 correspond and are equipped with.
The utility model, which has the advantage that, is sealed air preheater pipe using flexible gaskets, while utilizing seal boss
Cooperation sealing is carried out with the concave ring on cabinet, to realize effectively sealing.Wherein rubber pad can be used in flexible gaskets 32, seals convex
Flexible pad or ceramic blanket can be used in platform 33.
As preferred embodiment, locating piece 34, the locating piece are connected on the 31 end outer wall of ceramic washer
34 with connected on the outside of the seal boss 33.
In use, gasket 3 is inserted on 2 end of air preheater pipe, so that the groove and the seal boss 33 are one by one
It corresponds to and cooperates, and positioning 34 is located on 1 outside of cabinet, and then seal stronger.
The ceramic washer 31 is provided with screw thread on the outer wall far from described 1 one end of cabinet, and the ceramic washer 31 is separate
The nut 4 for being equipped with and being threadedly engaged on described 1 one end of cabinet, the nut 4 are located at locating piece 34 far from the cabinet 1 one
End.
Nut 4 is used to limit the position of the positioning fast 34, so that sealing is even closer.
