A method for manufacturing, processing and forming boiler economizer pipelines

Abstract

The invention relates to a method for manufacturing, processing and forming a pipeline of a boiler economizer, comprising a supporting table, a supporting plate, a cleaning mechanism, a conveying mechanism, a placing plate, a supporting roller, and a positioning and fixing mechanism, one end of the supporting table is welded with a supporting One end of the supporting plate is equipped with a cleaning mechanism, the side wall of the cleaning mechanism is connected with a conveying mechanism, one side of the conveying mechanism is installed with a placement plate, both sides of the supporting table are equipped with a positioning and fixing mechanism, and the supporting roller is installed through a fixing frame. At both ends of the support table, the metal shell A is welded to one end of the support plate, and one end of the metal shell A is provided with a drive unit, and the inner part of the metal shell A is movably installed with supporting rods, and the inside of the supporting rods is equidistantly embedded with bearings , the present invention can realize the rapid installation of the fins, and the installation device has strong stability, and the fins will not shake. At the same time, during the insertion process of the pipes, the outer wall of the pipes can be cleaned to ensure the normal execution of the welding process. .

Description

technical field [0001] The invention relates to the technical field of production of economizer pipelines, in particular to a method for manufacturing, processing and forming boiler economizer pipelines. Background technique [0002] The economizer is a device installed at the lower part of the boiler tail flue to recover the waste heat of the exhausted smoke. It heats the boiler feed water into a saturated water heating surface under the pressure of the steam drum. Because it absorbs the heat of the high-temperature flue gas, it reduces It improves the exhaust temperature of the flue gas, saves energy and improves efficiency, so it is called an economizer. Pipeline economizers are not limited by pressure and are generally made of carbon pipes with an outer diameter of 32 to 51 mm. Sometimes fins and ribs are added to the tube to improve heat transfer. [0003] However, the manufacturing, processing and forming methods of boiler economizer pipelines in the market currently...

AI Technical Summary

Problems solved by technology

[0003] However, the manufacturing, processing and forming methods of boiler economizer pipelines in the market currently have the following problems in the operation process: a. The traditional manufacturing process cannot quickly complete the positioning of the fins when welding the pipes and fins, that is, different effective At the same time, once the fins are subjected to external force during the welding process, the fins will shake to a certain extent, which will affect the welding effect; b. Due to the long storage time of the pipeline, or Affected by environmental factors, some impurities will appear on the surface wall of the pipeline, which will cause virtual welding to occur during the welding process.
