Description

Technical Field

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

[0002] In the modern steel structure processing industry, surface treatment is one of the key steps to ensure the durability and anti-corrosion performance of structural components. Traditional steel structure surface rust removal methods, such as rust removal of the surface of steel frames, generally use manual grinding, sandblasting and other rust removal methods. When dealing with a large number of steel frames for rust removal work, not only can't the rust removal work of the steel frame surface be carried out efficiently, but also the labor intensity is increased. When grinding and rust removing the surface of the steel frame, when the generated dust and waste are discharged wantonly, it will have an impact on the environment.

[0003] In the Chinese patent with the authorization announcement number CN211367746U, a surface rust removal device for steel structure production is disclosed, including a rust removal tank. A hanging rack is fixedly installed in the middle of the rust removal tank. In the middle of the bottom end of the rust removal tank below the hanging rack, a waterproof cover is fixedly installed. A motor is arranged inside the waterproof cover. The output shaft of the motor passes through the middle of the waterproof cover and is inserted and fixed with a connecting block. A rotating rod is fixedly installed in the middle of the connecting block. And the top end of the connecting block is rotatably installed with an air pipe. The air pipe extends out of the rust removal tank and is connected to the output end of an air pump. And the top surface of the rotating rod is evenly provided with air holes. When the device rusts the steel frame, the rust removal liquid is stirred by the rotating rotating rod and air pipe, so that the rust removal liquid is in full contact with the steel frame. However, after the rust removal work is completed, after the rust removal liquid is discharged from the rust removal tank, there will still be some used rust removal liquid, iron slag and rust left at the bottom of the rust removal tank. When these substances are not cleaned in time, it is easy to corrode and damage the rust removal tank, and it is also easy to block the drain outlet of the rust removal tank over time, affecting its normal use. Content of the Utility Model

[0004] In view of this, the utility model provides a surface rust removal device for steel structure processing, which can not only adsorb the iron slag and rust floating in the rust removal liquid through an electromagnetic component to avoid affecting the rust removal efficiency of the steel frame, but also scrape the rust and iron slag on the bottom surface of the rust removal tank into the collection box through a discharging component, and centrally collect and process the iron slag and rust through the collection box to avoid the iron slag and rust being discharged together with the rust removal liquid, affecting the recycling and treatment work of the rust removal liquid.

[0005] To solve the above technical problems, the utility model provides a surface rust removal device for steel structure processing, including a rust removal tank. A filter screen is arranged at the bottom of the rust removal tank. A first baffle is arranged at the bottom of the filter screen.

On the one hand, the influence of floating substances on the chemical reaction is reduced, and on the other hand, excessive iron slag and rust are prevented from blocking the filter screen and affecting the discharge of the rust removal liquid. After the rust removal work is completed, the iron slag on the electromagnetic rod is detached, and the iron slag and rust falling to the bottom of the rust removal tank are pushed into the collection box by the discharge component through the scraper, and the iron slag and rust are centrally collected by the collection box.

[0007] The rust removal component includes a high-pressure air pump arranged on the side wall of the rust removal tank and two brackets arranged inside the rust removal tank. The output end of the high-pressure air pump is connected with two connecting pipes. A gas guide pipe is arranged below each bracket, and a number of air outlet holes are arranged on each gas guide pipe. The gas guide pipe is connected with the connecting pipe. Air is extracted by the high-pressure air pump and pressurized to pass through the connecting pipe into the gas guide pipe and is ejected through the air outlet holes, so that a large number of bubbles are generated in the rust removal liquid, and the rust removal liquid reacts fully with the surface of the steel frame.

[0008] Each group of electromagnetic components includes a brushless motor, an electromagnetic generator, a magnetic guide rod, an electromagnetic rod, a linear chute, a bidirectional lead screw, two sliders and two razors.

The two sliders are symmetrically slidably arranged on the bidirectional lead screw, and the two razors are respectively connected to the side walls of the two sliders and the two razors are sleeved on the electromagnetic rod. The bidirectional lead screw is driven to rotate by the brushless motor, the sliders are driven to slide in the linear chute by the rotating bidirectional lead screw, and the sliders drive the razors to scrape the iron slag and rust on the electromagnetic rod, so that the iron slag adsorbed on the electromagnetic rod is detached from the electromagnetic rod and falls to the bottom of the rust removal tank.

[0010] The discharge component includes a guide groove arranged on the side wall of the rust removal tank, and a servo motor is fixedly arranged on the side wall of the guide groove. The end of the output shaft of the servo motor is connected with a screw rod.

[0031] The usage method of the present utility model: The present utility model is related to the surface rust removal work of steel structures, mainly used for steel frames. When rust removal of the steel frame is required, the through holes at the bottom and sides of the rust removal tank 1 need to be closed by the first baffle 3 and the second baffle 4 first. Subsequently, a rust removal liquid (composed of a surfactant, an organic acid, an accelerator, a corrosion inhibitor, and deionized water) is poured into the rust removal tank 1. Then, the steel frame is hoisted onto the support 611 inside the rust removal tank 1, and the rust removal component 61 is started to carry out the rust removal work on the rust and iron slag on the surface of the steel frame. During the rust removal work, the electromagnetic generator 625 in the electromagnetic component 62 magnetizes the electromagnetic rod 627 through the magnetic conduction rod 626, so that the electromagnetic rod 627 adsorbs the iron slag and rust floating in the rust removal liquid. After the rust removal work is completed, by pulling out the first baffle 3 at the bottom, the rust removal liquid is discharged out of the rust removal tank 1 through the filter screen 2. When the rust removal liquid is discharged, the filter screen 2 will filter the iron slag and iron slag above the filter screen 2. After the discharge of the rust removal liquid is completed, the second baffle 4 is pulled out. Subsequently, the electromagnetic generator 625 is turned off to demagnetize the electromagnetic rod 627. Then, the brushless motor 621 is started, and the bidirectional screw rod 622 is driven to rotate by the brushless motor 621, driving the two sliders 623 to move relatively in the linear chute 628, so that the two razors 624 sleeved on the electromagnetic rod 627 remove the iron impurities adsorbed on the electromagnetic rod 627, making the iron slag and rust fall to the bottom of the rust removal tank 1. Subsequently, the servo motor 631 in the discharging component 63 is started, and the screw rod 632 is driven to rotate by the servo motor 631, driving the movable block 634 to slide in the guide groove 633. When the movable block 634 slides, the fixed frame 635 moves together with the movable block 634, and the scraping plate 636 fixed inside the fixed frame 635 scrapes the rust and iron slag at the bottom of the rust removal tank 1 towards the collection box 5 for discharging and centralized treatment of the rust and iron slag.
