Furthermore, the large-pitch convection bank assembly is correspondingly welded with pipe brackets at the upper ends of the two ends and the middle three convection banks.
Further, the folded plate is integrally concave, the folded plate is vertically inserted between the adjacent convection tube bundles, and the upper end of the folded plate is welded on the connecting flat steel.
Furthermore, the folded plate is formed by folding 50mm on two sides of a steel plate with the thickness of 3mm, so that the folded plate is integrally concave.
Further, the convection bank assembly comprises an upper flue gas inlet end and a lower flue gas outlet end.
Further, the pipe bracket is arranged to be of an arc-shaped structure and is welded at the air inlet end of the convection bank in a fitting mode.
Has the advantages that: compared with the prior art, the utility model has the following advantages:
(1) the device integrally replaces a pipe clamp and a steel pipe in the prior art by a folded plate, the folded plate is formed by 50mm folded edges on two sides of a steel plate after 3mm, the folded plate is integrally of a concave structure and is vertically inserted between adjacent convection tube bundles during specific installation, and the insertion depth is determined according to the clearance of the convection tube bundles;
(2) the concrete installation of folded plate is fixed through connecting band steel and conduit saddle realization in this device, convection bank's upper end is that corresponding welding has the conduit saddle, and it is then corresponding welded fastening on the conduit saddle to connect the band steel, it fixes the inlet end at convection bank's flue gas wholly to connect the band steel, the mounted position with the folded plate is corresponding, the equal welded fastening in upper end of each folded plate is on connecting the band steel like this, thereby get up the folded plate rigidity, its stable in structure, difficult emergence is out of shape, and the dismouting installation is all very convenient.
