Forming method for anticorrosion layer of inner wall in large tank

Abstract

The invention discloses a forming method for an anticorrosion layer of an inner wall in a large tank. The forming method is finished through three times of spraying and based on a spraying device. Theforming method comprises the steps that 1, parameters of the inner surface of the sprayed tank and parameters of spraying materials are inputted in a control system; 2, a monitoring feedback system is started, the relative position parameters of the spraying device and the distance from the inner surface of the tank to a spraying nozzle of a spraying system and the relative position parameters inan inertial coordinate device of the distance are obtained; 3, the monitoring feedback system feeds back the two obtained parameters to the control system; 4, the control system transmits the obtained spraying implementation parameters to the spraying system, and the spraying system carries out spraying operation; and 5, and the monitoring feedback system collects the spraying implementation surface coordinates in real time and compares the spraying implementation surface coordinates with the target point position coordinates of the preset anticorrosion layer surface. The forming method for the anticorrosion layer of the inner wall in the large tank can realize intelligent spraying construction of the anticorrosion layer in the tank and is high in efficiency.

Description

technical field [0001] The invention relates to a method for forming an anticorrosion layer on the inner wall of a large tank. Background technique [0002] With the improvement of the quality and performance requirements of large-scale anti-corrosion storage tanks in petroleum, pharmaceutical and other chemical industries, large-scale steel mesh plastic storage tanks using rotational molding are widely used due to their extremely high cost performance. In the current storage tank processing industry, rotational molding processing technology is widely used. [0003] Rotational molding is a thermoplastic hollow molding method, that is, first inject powdery or pasty or monomeric materials into the mold, and through heating the mold and biaxial rolling and rotating, the material is evenly filled in the mold by its own gravity. The cavity is melted, and the hollow product is obtained after demoulding after cooling. The rotation speed of rotational molding is not high, and the ...
