Description

Technical Field

[0001] The utility model relates to the technical field of pipeline coating drying, in particular to an improved pipeline inner wall anticorrosive coating drying device. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. The fluid can also be conveyed by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. Pipelines play a vital role in oil transportation.

[0003] Before the use of oil pipelines, sandblasting is performed on their inner walls for anti-corrosion. In terms of heavy-duty anti-corrosion, the thicker the anti-corrosion coating, the better the anti-corrosion effect. However, it is not easy to dry. Usually, natural air drying or drying equipment is used to dry the inner wall of the pipeline. Usually, most drying devices are driven by sliding wheels, which inevitably come into contact with the coating on the inner wall of the pipeline. The movement of the sliding wheel in the pipeline can easily damage the coating on the inner wall of the pipeline and cause the coating to crack, thereby reducing the anti-corrosion effect, which is not conducive to the long-term use of the oil pipeline and the maintenance cost will also increase accordingly. Utility Model Content

In terms of heavy corrosion protection, the thicker the anti-corrosion coating, the better the anti-corrosion effect, but it is not easy to dry. Usually, natural air drying or drying with a drying device is adopted to dry the inner wall of the pipeline. Usually, most drying devices are driven by a sliding wheel, which inevitably comes into contact with the coating on the inner wall of the pipeline. The sliding wheel can easily damage the coating on the inner wall of the pipeline when it moves in the pipeline, causing the coating to rupture, thereby reducing the anti-corrosion effect, which is not conducive to the long-term use of the oil pipeline, and the maintenance cost will also increase accordingly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an improved pipeline inner wall anticorrosive coating drying device, comprising a movable seat, on which an adjustable drying mechanism is provided;

[0008] Furthermore, a connecting rod is fixedly installed on the right side of the movable plate, a drying box is fixedly installed on the right side of the connecting rod, and a mesh plate is fixedly installed inside the drying box.

[0009] Furthermore, a heating wire is arranged on the left side of the mesh plate, a blowing fan is installed on the right side of the mesh plate, and an air outlet duct is arranged on the right side of the drying box.
