Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, in particular to a rust removal device for the surface of a steel structure before a fireproof coating is applied. Background Art

[0002] Before applying fire-retardant coating on steel structures, surface rust removal is an important step to ensure the adhesion and durability of the coating. This is mainly because steel is a metal and the air contains water vapor, which adheres to the surface of the steel structure and reacts with oxygen, making it very easy to rust.

[0003] Existing rust removal technology mostly uses manual grinding for rust removal, but this method is not only inefficient, but also easily generates a large amount of dust and rust debris during the work process, causing pollution to the working environment and endangering the health of operators. For example, a Chinese patent discloses "A rust removal device for the surface of a steel structure before fire-retardant coating", and its application number is "CN202323107911.8". It starts a high-pressure pump. At this time, the water in the water tank passes through the high-pressure pump and the hose in turn, and is sprayed onto the workpiece by the water pipe, so that the workpiece can be cleaned; the cleaning mechanism is set up to facilitate the cleaning of the workpiece, but it cannot effectively handle the dust and rust debris generated during the rust removal process. If not handled properly, it will scratch the workers and easily infect them with tetanus bacteria. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art, and to provide a device for removing rust from the surface of a steel structure before a fire-retardant coating is applied. Through the cooperation of an exhaust fan, a filter screen and a treatment box, the exhaust fan and the first filter screen can quickly remove dust, and the mixed rust debris is blocked by the first filter screen and continues to remain inside the shell. The dust enters the treatment box after being filtered, and the nozzle in the treatment box sprays water mist to reduce dust. The nozzle releases clean water to flush the rust debris into the second guide groove and falls on the inclined second filter screen. The rust debris is led to the collection tank by the impact of the water flow and finally flows into the collection box, and the sewage enters the sewage collection box, ensuring the effective separation and separate collection of dust and rust debris, reducing dust pollution in the air, and keeping the workbench clean, thereby improving the rust removal efficiency.
