Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting devices, in particular to a sandblasting device for a heat exchanger. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a higher-temperature fluid to a lower-temperature fluid, allowing the fluid temperature to reach the specified process temperature. Heat exchangers require sandblasting during production, so a sandblasting room is required.

[0003] A large amount of dust is often emitted during sandblasting. When sandblasting a heat exchanger manually, it is easy to cause harm to the health of workers, and the heat exchanger is not easy to flip over during sandblasting. Therefore, providing a sandblasting device that can reduce dust emission and facilitate flipping of the heat exchanger is a technical problem that technical personnel in this field urgently need to solve.
