Description
Technical field
The present invention relates to the coal economizer structure technical field of coal-powder boiler, recirculating fluidized bed, is specially a kind of economizer piping
Erecting by overhang.
Background technology
In coal-powder boiler, recirculating fluidized bed, back-end ductwork space is limited, often arranges level-one economizer, drop within the walls in bag
Low smoke temperature improves the feed temperature into drum at the same time.But economizer piping here can not be hung by ventilation beam branch, usually be adopted
Fixed form is to be directly welded at pipe clamp on economizer upper collecting chamber, in long-play in use, economizer tube comes
Under the washing away of flue gas, easily there is fatigue crack in the swing of easy generating period, the weld seam between pipe clamp and header, finally leads
Cause dropping for piping.
The content of the invention
To solve the above-mentioned problems, the present invention provides a kind of economizer piping erecting by overhang, it can ensure economizer
The firm connection of pipe and upper collecting chamber, will not fall off phenomenon.
Its technical solution is such：A kind of economizer piping erecting by overhang, it includes upper collecting chamber, the upper collecting chamber lower end
Pipe clamp is provided with, economizer tube is provided with the pipe clamp, it is characterised in that the upper collecting chamber bottom is installed with pre-buried gold
Belong to plate, the built-in metal plate and the mounting hole that cooperation is had at the top of the pipe clamp, run through in the mounting hole and be welded with
Connecting rod.
It is further characterized by, and the connecting rod is round steel；
The upper collecting chamber bottom is installed with multiple built-in metal plates, the upper collecting chamber lower end be provided with it is described pre-buried
The pipe clamp of metallic plate corresponding number, each round steel run through three to four built-in metal plates, the round steel and the pipe clamp top
Portion is welded to connect；
Each built-in metal plate on pipe clamp top with having two mounting holes.
After adopting the structure of the invention, since the pipe clamp of economizer tube and the built-in metal plate of upper collecting chamber bottom are solid by opening
Kong Bingyong fixed connecting rods are determined through connection, economizer tube is firmly hung in upper collecting chamber lower end, even if prolonged operation makes admittedly
The welding determined around connecting rod cracks, and will not fall off phenomenon, ensure that the firm company of economizer tube and upper collecting chamber
Connect.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is structure side schematic view of the present invention.
Embodiment
See Fig. 1, shown in Fig. 2, a kind of economizer piping erecting by overhang, it includes upper collecting chamber 1, and 1 lower end of upper collecting chamber is provided with
Pipe clamp 5, economizer tube 2 is provided with pipe clamp 5, and 1 bottom of upper collecting chamber is installed with pre-embedded steel slab 3, pre-embedded steel slab 3 and pipe clamp 5
Top has the mounting hole of cooperation, runs through in mounting hole and is welded with round steel 4.
1 bottom of upper collecting chamber is installed with six pre-embedded steel slabs 3, and 1 lower end of upper collecting chamber is provided with pipe clamp 5 corresponding with six,
Each round steel 4 runs through three pre-embedded steel slabs 3, and round steel 4 is welded to connect with the top of pipe clamp 5.
Two mounting holes are had on each pre-embedded steel slab 3 and pipe clamp 5 top, run through round steel 4 in each mounting hole,
It is further ensured that the firm of connection.
