Evenly-spraying device of nanometer self-cleaning coating for coke oven crude gas ascension pipe

Abstract

The invention discloses an evenly-spraying device of nanometer self-cleaning coating for a coke oven crude gas ascension pipe. The evenly-spraying device comprises a center-adjusting support, a rotary suspending support and a shell. The center-adjusting support comprises a first center-adjusting support body, a second center-adjusting support body, a diameter-adjusting device and pulleys. A material spraying head is suspended on the rotary suspending support, a spraying pipe is arranged between the rotary suspending support and the material spraying head, and the spraying pipe is assembled on the rotary suspending support and horizontally arranged. The evenly-spraying device further comprises a material spraying pump, a material conveying pipe connected with the material spraying pump, an image detector and an image calculating module connected with the image detector. The material conveying pipe communicates with the spraying pipe through a hollow cavity of the rotary suspending support, and the image calculating module is in electric connection with a controller. According to the evenly-spraying device of the nanometer self-cleaning coating for the coke oven crude gas ascension pipe, the coating sprayed from the material spraying head is scanned through the image detector, the data are sent to the image calculating module, and thickness evenness of a coating is judged by the image calculating module according to the coating surface change; and the material spraying pump and a double-acting air cylinder are controlled by the controller to adjust the thicknesses of the coating.

Description

technical field [0001] The invention relates to the technical field of spraying, in particular to a uniform spraying device for nanometer self-cleaning coatings on coke oven raw gas riser pipes. Background technique [0002] Spraying is a coating method in which the paint is atomized by spraying tools such as a spray gun and then sprayed on the workpiece to be coated. The traditional spraying method is generally that the spraying engineer holds the spray gun, and completes the spraying treatment of the hand oil on the surface of the product according to the daily work experience. The spraying quality of the sprayed parts has a great influence, and because the process speed and route are not easy to control stably in the manual spraying operation, the spraying thickness on the surface of the sprayed parts is uneven, and there is a serious waste of manpower in the case of a large spraying area The disadvantage of this is that not only the labor intensity of the workers is too...

AI Technical Summary

Problems solved by technology

However, the prior art has the following technical problems: one is that the structure is complex and the spraying cost is higher due to the installation of spray guns, supporting wheels and air compressors; uniform

Similarly, the nozzle spraying is uneven and the degree of automation in the spraying process is low, which requires manual control. In this process, the probability of uneven spraying will be increased, and a uniform spraying and high degree of automation is required. Uniform spraying device to solve the problem, to uniform spraying of coke oven raw gas riser pipe
