The flexible materials such as expanding end aluminium silicate wool are sealed, and sealing effect is poor, and economizer section inleakage is big, causes heat waste
It loses, influences boiler efficiency.
Invention content
To solve the above problems, the present invention provides a kind of sealing structure applied to economizer ventilation beam, welding difficulty
Low, sealing effect is good.
A kind of sealing structure applied to economizer ventilation beam of the present invention, including economizer ventilation beam, truss-steel beam,
Economizer backplate and sealing device, the economizer backplate are installed on the truss-steel beam, the economizer ventilation beam expanding end
It is located on the truss-steel beam across the economizer backplate, the sealing device is set in the economizer ventilation beam expanding end simultaneously
It is welded respectively with the economizer backplate and the truss-steel beam.
It is further improved, the sealing device includes bending section, pars contractilis and stop nut, the bending section head end and institute
The welding of economizer backplate is stated, the bending section tail end is connect with the pars contractilis head end, and limited block is equipped with above the pars contractilis,
The stop nut is connect across the limited block with the bending section.
The sealing device is set in the expanding end of ventilation beam, and sealing device is welded with economizer backplate and truss-steel beam respectively
It connecing, welding difficulty is low, is not easy desoldering, and limited block is preferably located at pars contractilis end, and stop nut is tightened or unclamped on limited block,
The release amount for adjusting pars contractilis, to adapt to the expansion or shrinkage of ventilation beam expanding end.
It is further improved, the pars contractilis is ripple struction, and the pars contractilis is equipped with several reinforcing rings, the reinforcing ring
It is located at the sunk part of the ripple struction, pars contractilis is made more securely to be hardly damaged.
It is further improved, the bending radius of the bending section is 50mm, and welding effect is best.
It is further improved, the sealing device is made of thickness of the steel plate punched of 2mm-3mm.
The beneficial effects of the invention are as follows：Simple in structure, welding difficulty is low, is not easy desoldering, and sealing effect is good, and equipment operation is steady
Dingan County is complete.
Description of the drawings

Portion 42 is integrally formed, and the bending radius of the bending section 41 is 50mm；The pars contractilis 42 is bellows, is covered on the bellows
Equipped with several reinforcing rings 45, the end of the pars contractilis 42 is equipped with limited block 44, and the stop nut 43 passes through the limited block
44 connect with the bending section 41.
4 sealing surface of the sealing device is welded with truss-steel beam 2 and economizer backplate 3 respectively, by the swollen of economizer ventilation beam
Swollen end sealing, adjusts the stop nut release amount on the sealing device 4, sealing device is made to adapt to the economizer ventilation beam
Expansion, and can stop nut and limited block collective effect, can prevent sealing device from excessively expanding；The economizer backplate can be with
Play the role of support guide to the economizer ventilation beam, while resistance of the ventilation beam to flue gas can be increased, prevents local cigarette
Speed is excessively high, makes safe and stable equipment operation.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
