Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, in particular to a rapid rust removal device for steel railings. Background Technique

[0002] A rapid rust removal device for steel railings is a special equipment that uses high-speed jet of sand grains or other hard particles to impact the metal surface to remove impurities such as rust, old paint layer, dirt and oxide layer. This technology has the characteristics of high efficiency, thoroughness and wide application range in the field of metal surface treatment. During operation, high-pressure air or water flow passes through a special nozzle, carrying sand grains or other hard particles and spraying them onto the metal surface to be treated at an extremely high speed. These high-speed abrasive particles impact and peel off the rust layer, dirt and aging coating on the surface with a huge impact force, and at the same time produce a certain cutting effect, so that the metal surface reaches the required cleanliness and roughness, providing an ideal base for subsequent painting, anti-corrosion and other processes.

And the air drying groove 24 makes it easier for the shielding cloth 25 to dry quickly, thereby facilitating the shielding of sandblasting and avoiding the situation of splashing.

[0029] Working principle: Place the steel railing into the rust removal tank 3. Subsequently, the rust removal spraying plate group 4 uses compressed air and water as power to spray abrasives onto the surface of the steel railing at high speed through nozzles, and utilizes the impact force and friction force to remove rust, thereby completing the rust removal work of the steel railing. Before sandblasting rust removal, it is necessary to carry out necessary pretreatment on the steel railing, such as removing large rust spots or oil stains on the surface. After sandblasting rust removal, carry out necessary post-treatment, such as cleaning and drying, to improve the quality of subsequent processes such as painting or spraying. However, the existing rust removal devices do not have such operations, so it is necessary to improve this. First, place the steel railing into the treatment box 5 filled with water. Subsequently, press the pressing discharge end 10 to convey the dimethylformamide liquid in the feeding bottle 9 into the treatment box 5 to remove the oil stains on the surface of the steel railing. Subsequently, the pole lifting electric motor 6 works to drive the pushing plate 7 to move, and lift and take out the steel railing after oil removal. Subsequently, carry out rust removal work on it. After the rust removal work, the water pump 14 works to convey the external water into the water spraying plate 16, and at this time, the water spraying plate 16 is located above the steel railing. Subsequently, clean the steel railing. After the cleaning is completed, the angle motor 15 works to drive the water spraying plate 16 to rotate by 90 degrees, so that the water spraying plate 16 is no longer above the steel railing. Subsequently, the air drying fan 12 works to dry the steel railing, thereby completing the pretreatment of the steel railing. When spraying on the steel railing, spraying splashing may occur, so it is necessary to improve this. First, adsorb the first magnet 18 and the second magnet 19 to install the shielding plate 20. Subsequently, fix the screw rod 22 into the screw groove 21 to install the replacement plate 23. Then, use the shielding cloth 25 to shield the spraying. And when the shielding cloth 25 needs to be cleaned, disassemble the replacement plate 23 to clean the shielding cloth 25, and the air drying groove 24 is more likely to enable the shielding cloth 25 to dry quickly, thereby facilitating the shielding of sandblasting and avoiding the occurrence of splashing.
