Boiler economizer forming manufacturing device and method thereof

Abstract

The invention relates to a boiler economizer forming manufacturing device and a method thereof. The boiler economizer forming manufacturing device comprises a bottom plate, a bending unit, an auxiliary unit and a supporting unit, the bending unit is installed at the upper end of the bottom plate, the auxiliary unit is installed at the right end of the bending unit, and the supporting unit is arranged behind the bending unit. According to the boiler economizer forming manufacturing device, the problems that when an economizer pipe is bent and formed through existing equipment, the pipe diameterof the bent position of the economizer pipe cannot be protected during bending, so that the structural integrity of the pipe is damaged, the phenomenon that the pipe cannot be used easily occurs, materials are wasted, and the bending and forming effect of the economizer pipe is reduced can be solved; and meanwhile, the problems that when the economizer pipes are bent, the phenomenon of excessivebending is likely to happen, and therefore the widths of the economizer pipes are inconsistent, it cannot be guaranteed that the bent economizer pipes are horizontal, welding treatment between the economizer pipes is inconvenient, and the assembling difficulty of an economizer is increased are solved.

Description

technical field [0001] The invention relates to the technical field of boiler energy saving, in particular to a boiler economizer forming device and a method thereof. Background technique [0002] The economizer is a device installed in the lower part of the flue at the tail of the boiler to recover the waste heat of the exhausted smoke. It heats the boiler feed water into the heating surface of saturated water under the pressure of the steam drum. The exhaust temperature of the flue gas is reduced, energy is saved, and the efficiency is improved; the steel tube economizer is not limited by pressure and can be used as a boiling type, and sometimes fins and ribs are added to the tube to improve the heat transfer effect. [0003] At present, the existing equipment usually has the following deficiencies when bending and forming the economizer pipe fittings: 1. The existing equipment cannot protect the pipe diameter at the bend of the economizer pipe fitting during bending, ther...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that existing equipment cannot protect the pipe diameter at the bend of the economizer pipe fittings when bending and forming the economizer pipe fittings, thereby destroying the integrity of the pipe fitting structure and easily There is a phenomenon that the pipe fittings cannot be used, which leads to waste of materials and reduces the effect of the bending and forming of the economizer pipe fittings. Inconsistencies in the width of the space, and can not ensure that the bent economizer pipe fittings are in a horizontal position, which is not convenient for welding between economizer pipe fittings, and increases the difficulty of economizer assembly and other problems
