Steel conduit inner wall anticorrosion device and method

Abstract

The invention discloses a steel conduit inner wall anticorrosion device and method; the device comprises a support for obliquely holding steel conduits, a high pressure torch for spraying anticorrosion paint to the inner walls of the steel conduits, and an anticorrosion actuator that provides the anticorrosion paint for the high pressure torch; the anticorrosion actuator comprises a moving platform, a pressure container, a vacuum pump for vacuumizing the pressure container, a paint mixing bucket for conveying anticorrosion paint to the pressure container, a pressurizer for pressurizing the pressure container, and a control cabinet for controlling spraying of the anticorrosion paint, wherein the pressure container, the vacuum pump, the paint mixing bucket, the pressurizer and the control cabinet are arranged on the moving platform. The method comprises the steps of I, testing pressure; II, mixing the anticorrosion paint; III, vacuumizing the pressure container; IV, adding the paint into the pressure container; V, spraying the paint to the inner walls of the steel conduits; VI, collecting the anticorrosion paint flowing out of the steel conduits. The anticorrosion mixed well in the paint mixing bucket is stored in the sealed pressure container via the vacuum pump, so that less of the anticorrosion paint volatilizes; the anticorrosion paint is driven to flow in the steel conduits via high pressure through the high pressure torch, so that the coatings on the inner walls of the steel conduits are smooth and free of steel exposure.

Description

technical field [0001] The invention belongs to the technical field of steel conduit inner wall anticorrosion, and in particular relates to an anticorrosion device and method for the inner wall of a steel conduit. Background technique [0002] At present, steel pipes are used for strong and weak electricity and fire protection system piping in public welfare public cultural buildings. In order to prevent rust and corrosion on the inner wall of the pipe, which will affect the subsequent threading in the pipe and the insulation of the outer skin of the wire, it is necessary to do anti-corrosion treatment on the inner wall of the pipe. The inner wall of the steel pipe Anti-corrosion requires that the surface of the coating should be smooth, free of bubbles, peeling, and iron leakage. When the inner wall of the pipeline is anti-corrosion, the proportion of anti-rust paint and thinner should be appropriate. The traditional method of anti-corrosion on the inner wall of steel pipes...

Problems solved by technology

There are several problems in such an operation method in the field: First, the thinner is volatile, and the adjusted anti-rust paint becomes thicker and thicker during use, and the thinner needs to be added many times during the construction process, and the mixing ratio between it and the paint is not easy Control, the anti-corrosion quality is difficult to control, and the construction process is time-consuming and consumable; second, the thinner contains toxic substances, which are extremely harmful to the workers' bodies and the surrounding environment during the volatilization process; third, the anti-rust paint is poured into the pot The method is gravity flow, the flow rate is slow and the coating is uneven, and the anti-corrosion paint is not attached in some areas, and it takes a long time
