AI Technical Summary

Technical Problem

Existing boiler anti-corrosion coating spraying equipment cannot flexibly adjust the spraying angle and the normal distance between the working surface when facing cylindrical enclosed spaces with varying curvature and long depth, resulting in uneven coating thickness. In addition, manual operation is labor-intensive and the environment is harsh.

Method used

The system employs a combination design of frame, lifting platform, swing spraying assembly, and overlapping auxiliary assembly. The frame is moved by the moving assembly, the lifting platform adjusts the spraying height, the swing rod on the support column swings back and forth under the drive assembly, the spray gun scans the circumferential wall of the boiler, and the overlapping auxiliary assembly maintains the relative position of the spray gun and the wall surface, thus realizing mechanized automatic spraying. The spraying parameters can be flexibly adjusted through a servo motor and crank-connecting rod mechanism.

Benefits of technology

It significantly improves the uniformity of boiler inner wall coating and construction efficiency, reduces labor intensity, ensures the uniformity of coating thickness and the stability of spraying distance, and adapts to boiler inner walls with different diameters and curvatures.

Abstract

This utility model discloses a boiler anti-corrosion coating spraying device, relating to the field of boiler maintenance technology. It includes a frame, a movable component at the bottom of the frame, a lifting platform on the frame, a pressurized material tank on the lifting platform, and a swing spraying component on the lifting platform. The swing spraying component includes a support column, a swing rod at the end of the support column, a drive component on the support column to drive the swing rod to reciprocate, and a spray gun at the end of the swing rod. An overlap auxiliary component is also provided on the support column. The movable component drives the frame to move along the furnace axis. Under the pressure of an air compressor, the pressurized material tank stably delivers the anti-corrosion coating to the spray gun through pipelines. The swing rod, driven by the drive component, reciprocates, causing the spray gun to automatically spray by circumferentially scanning the inner wall of the boiler. This replaces manual hand-held spraying, reduces labor intensity, improves coating uniformity and construction efficiency, and facilitates integrated application of anti-corrosion coating and insulation for oil boiler pipelines.
