Description

Technical Field

[0001] This utility model belongs to the field of pipeline inner wall corrosion prevention and insulation, and in particular relates to a pipeline inner wall spraying device. Background Technology

[0002] Pipeline inner wall coating typically uses anti-corrosion and heat-insulating materials. These materials can resist corrosion from environmental factors such as acids, alkalis, and humidity, while also regulating the temperature of the medium inside the pipe. The anti-corrosion and heat-insulating layer effectively isolates the external medium from contact with the pipe surface, reducing corrosion. At the same time, high-quality insulation materials can effectively reduce heat transfer loss in the pipeline, lowering energy consumption. This extends the service life of the pipeline and improves energy efficiency.

[0003] Comparing with Chinese patent CN218590902U, which discloses a pipe inner wall spraying technology, a pipe inner wall spraying device is provided. The device includes a cylindrical cylinder with a traveling mechanism mounted on its outer wall. A connecting cylinder is installed through one end of the cylinder. A conveying assembly is installed inside the cylinder, and its output end is connected to the connecting cylinder. A hollow plate is rotatably connected to one end of the connecting cylinder. A spray nozzle is mounted on the side wall of the hollow plate. A blower, a heating box, and an air outlet plate are respectively mounted on one side wall of the hollow plate. The output end of the blower is connected to the heating box. Hot air enters the air outlet plate through a connecting pipe and is then blown out, thus accelerating the drying of the coating. A hydraulic cylinder output drives an annular plate to move. The annular plate, through a connecting rod, drives a connecting rod to adjust the angle, causing the moving mechanism to contact the inner wall of the pipe, thereby adapting to pipes of different diameters and lengths.

[0004] However, because the coating sinks under gravity before it adheres to the inner wall of the pipe, the coating thickness at the bottom of the pipe is greater than that at the top, resulting in uneven coating distribution and even clumping at the bottom. Therefore, a new device needs to be designed. Utility Model Content
