Description

Technical Field

[0001] This utility model relates to the field of rust removal technology, and in particular to a rust removal device for steel structures. Background Technology

[0002] There are three common methods for rust removal from steel structures: manual grinding or scraping with tools, mechanical grinding or impact to remove rust from the steel structure surface, and chemical reaction between acid and rust. Manual and mechanical rust removal are only effective on the surface of regular steel parts and are insufficient for internal rust removal. For complex parts or when internal rust removal is required, acid pickling is often used. However, current acid pickling methods often involve placing the steel parts directly into the pickling solution and waiting for the reaction to occur. Conventional static acid pickling is prone to uneven rust removal and low efficiency due to poor acid flow, and localized accumulation can lead to excessive corrosion and leave many dead zones. Therefore, there is an urgent need to develop a steel structure rust removal device that utilizes the synergistic effects of rotation, vibration, and bubble impact to significantly improve pickling efficiency through multi-angle agitation, high-frequency penetration, and scouring force, eliminating dead zones and ensuring uniform and thorough rust removal. This device would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide a steel structure rust removal device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A steel structure rust removal device includes an acid pickling and rust removal box, a top cover, a conduit, a drive mechanism, an air pump, a hose, an auxiliary rust removal mechanism, and a storage mesh box. The top cover is detachably clipped onto the top of the acid pickling and rust removal box. The conduit is rotatably connected to the acid pickling and rust removal box. The storage mesh box is fixedly installed on the lower half of the conduit. A diversion pipe connected to the bottom of the conduit is fixed thereto, and multiple air outlets are installed on the diversion pipe. The drive mechanism is installed on the top of the acid pickling and rust removal box and is used to drive the conduit to rotate back and forth. The air pump is fixed on the top of the acid pickling and rust removal box. The air outlet of the air pump is connected to the top of the conduit via a hose. The auxiliary rust removal mechanism is fixedly installed in the lower half of the pickling and rust removal box and inserted into the pickling and rust removal box. The drive mechanism includes: an electric telescopic rod, a rack, a gear, a slider, and a slide rail. The electric telescopic rod is fixed to the top of the pickling and rust removal box. The telescopic end of the electric telescopic rod is fixed to the rack. The rack meshes with the gear. The gear is fixed to the conduit. A slider is fixed to the bottom of the rack. The slider is slidably installed on the slide rail. The slide rail is fixed to the top of the pickling and rust removal box.

[0006] Preferably, the auxiliary rust removal mechanism includes: a water tank, an ultrasonic vibrator, and extension pipes. The water tank is fixed to the outside of the pickling and rust removal box, the ultrasonic vibrator is fixed to the water tank, the vibrating head of the ultrasonic vibrator is inserted into the water tank, and two extension pipes connected to the side of the water tank are fixed thereto. The extension pipes are inserted into the pickling and rust removal box, and both the water tank and the extension pipes are filled with water.

[0007] Preferably, the lower end of the pickling and rust removal box is provided with a drain pipe, and a plug is detachably connected to the drain pipe via a sealing pipe thread.

[0008] Preferably, the pickling and rust removal box, drain pipe, plug, top cover, conduit, diversion pipe, vent, water tank, extension pipe and storage mesh box are all made of fiberglass.

[0009] The beneficial effects of this utility model are as follows: When using this steel structure rust removal device, first place the steel structure parts to be rusted into the storage mesh box, then add pickling solution to the pickling and rust removal tank to submerge the storage mesh box. Next, cover the top, start the drive mechanism, air pump, and auxiliary rust removal mechanism. The drive mechanism drives the guide tube and storage mesh box to rotate back and forth, and the storage mesh box drives the steel structure parts inside to rotate back and forth. This rotation continuously changes the contact angle and position between the workpiece and the acid solution, promoting uniform acid penetration, accelerating rust removal, and improving the efficiency and uniformity of pickling and rust removal. An ultrasonic vibrator is used to vibrate the water in the storage tank and extended pipe. Vibration is transmitted to the pickling solution within the pickling and rust removal tank via an extended pipe. This vibration enhances the contact and penetration between the acid and the rust layer through high-frequency mechanical agitation, accelerating rust removal and reducing dead zones. Simultaneously, it inhibits excessive corrosion caused by localized acid stagnation, improving rust removal efficiency and uniformity. An air pump blows air into the conduit and distribution pipes, expelling a large number of bubbles through the air outlet. The disturbance and impact force generated by the formation and collapse of these bubbles in the acid strengthens the acid's scouring and penetration of the rust layer, accelerating rust removal and eliminating residual rust in dead zones, thus improving rust removal efficiency and cleanliness. After rust removal, the pickling solution is drained, and the steel structural parts can be removed. In summary, this invention, through the synergistic effect of rotation, vibration, and bubble impact, significantly improves pickling and rust removal efficiency, eliminates dead zones, and ensures uniform and thorough rust removal through multi-angle agitation, high-frequency penetration, and scouring force.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] See Figures 1-6In this embodiment of the present invention, a steel structure rust removal device includes an acid pickling and rust removal box 1, a top cover 2, a conduit 3, a drive mechanism 4, an air pump 5, a hose 6, an auxiliary rust removal mechanism 7, and a storage mesh box 9. The acid pickling and rust removal box 1 is used to store pickling solution, which is used to remove rust from the surface of the steel structure. The top cover 2 is detachably clipped onto the top of the acid pickling and rust removal box 1. The conduit 3 is rotatably connected to the acid pickling and rust removal box 1. The storage mesh box 9 is fixedly installed in the lower half of the conduit 3 and is used to place the steel structure parts that need to be rusted. The bottom of the conduit 3 is fixed with... A diversion pipe 301 is connected to the pickling and rust removal box 1, and multiple air outlets 302 are installed on the diversion pipe 301. The drive mechanism 4 is installed on the top of the pickling and rust removal box 1 and is used to drive the guide tube 3 to rotate back and forth. The drive mechanism 4 drives the guide tube 3 to rotate half a circle clockwise and then half a circle counterclockwise, and so on. The air pump 5 is fixed to the top of the pickling and rust removal box 1, and the air outlet of the air pump 5 is connected to the top of the guide tube 3 through a hose 6. The auxiliary rust removal mechanism 7 is fixedly installed in the lower half of the pickling and rust removal box 1 and inserted into the pickling and rust removal box 1. When in use, the steel structure parts that need to be derusted are first placed in the pickling and rust removal box 1. Inside the storage mesh box 9, pickling solution is added to the pickling and rust removal box 1 to submerge the storage mesh box 9. Then, the top cover 2 is closed, and the drive mechanism 4, air pump 5, and auxiliary rust removal mechanism 7 are started. The drive mechanism 4 drives the guide tube 3 and the storage mesh box 9 to rotate back and forth. The storage mesh box 9 drives the steel structural parts inside to rotate back and forth. The rotation can continuously change the contact angle and position between the workpiece and the acid solution, promote the uniform penetration of the acid solution, accelerate the peeling of the rust layer, and improve the pickling and rust removal efficiency and uniformity. The auxiliary rust removal mechanism 7 vibrates the pickling solution in the pickling and rust removal box 1. The vibration can be controlled by a high-frequency machine. Mechanical disturbance enhances the contact and penetration of acid and rust layer, accelerates rust layer peeling and reduces dead corners, while inhibiting excessive corrosion caused by local acid retention, improving rust removal efficiency and uniformity. Air is blown into the conduit 3 and the branch pipe 301 by the air pump 5, and a large number of bubbles are discharged through the air outlet 302. The disturbance and impact force generated when the bubbles are generated and burst in the acid can enhance the flushing and penetration of acid on the rust layer, accelerate rust layer peeling and remove dead corner residual rust, and improve rust removal efficiency and cleanliness. The top of the pickling and rust removal box 1 is equipped with an exhaust hole to facilitate the discharge of bubbles from the pickling solution.

[0021] The lower end of the pickling and rust removal box 1 is provided with a drain pipe 101. A plug 102 is detachably connected to the drain pipe 101 through a sealing pipe thread. By unscrewing the plug 102, the liquid in the pickling and rust removal box 1 can be discharged from the drain pipe 101.

[0022] The driving mechanism 4 includes: an electric telescopic rod 401, a rack 402, a gear 403, a slider 404, and a slide rail 405. The electric telescopic rod 401 is fixed to the top of the pickling and rust removal box 1. The telescopic end of the electric telescopic rod 401 is fixed to the rack 402. The rack 402 meshes with the gear 403. The gear 403 is fixed to the guide tube 3. The bottom of the rack 402 is fixed with the slider 404. The slider 404 is slidably mounted on the slide rail 405. The slide rail 405 is fixed to the top of the pickling and rust removal box 1. In use, the electric telescopic rod 401 drives the rack 402 to move back and forth. The back and forth movement of the rack 402 drives the gear 403 and the guide tube 3 to rotate back and forth. The guide tube 3 drives the storage mesh box 9 to rotate back and forth. In addition, the back and forth rotation of the guide tube 3 (rotating half a circle forward and then half a circle backward, and so on) can prevent the hose 6 from getting tangled.

[0023] The auxiliary rust removal mechanism 7 includes: a water storage tank 701, an ultrasonic vibrator 702, and an extension tube 703. The water storage tank 701 is fixed to the outside of the pickling and rust removal box 1. The ultrasonic vibrator 702 is fixed to the water storage tank 701, and the vibrating head of the ultrasonic vibrator 702 is inserted into the water storage tank 701. Two extension tubes 703 connected to the side of the water storage tank 701 are fixed thereto. The extension tubes 703 are inserted into the pickling and rust removal box 1. Both the water storage tank 701 and the extension tubes 703 are filled with water. In use, the ultrasonic vibrator 702 vibrates the water in the water storage tank 701 and the extension tubes 703, and the vibration is transmitted to the pickling solution in the pickling and rust removal box 1 through the extension tubes 703.

[0024] A PLC controller 8 is fixedly installed on the top of the pickling and rust removal box 1. The electric telescopic rod 401, the air pump 5 and the ultrasonic vibrating rod 702 are controlled by the PLC controller 8 respectively.

[0025] The pickling and rust removal box 1, drain pipe 101, plug 102, top cover 2, conduit 3, diversion pipe 301, air outlet 302, water storage tank 701, extension pipe 703 and material storage mesh box 9 are all made of fiberglass. Fiberglass has extremely strong corrosion resistance and high strength.

[0026] Working Principle: When using this steel structure rust removal device, first place the steel structure parts requiring rust removal into the storage mesh box 9. Then, add pickling solution to the pickling and rust removal tank 1 to submerge the storage mesh box 9. Next, cover the top cover 2, and start the drive mechanism 4, air pump 5, and auxiliary rust removal mechanism 7. The drive mechanism 4 drives the conduit 3 and the storage mesh box 9 to rotate back and forth. The storage mesh box 9 drives the steel structure parts inside to rotate back and forth. This rotation continuously changes the contact angle and position between the workpiece and the acid solution, promoting uniform acid penetration, accelerating rust removal, and improving the efficiency and uniformity of pickling and rust removal. The ultrasonic vibrator 702 vibrates the water in the water storage tank 701 and the extension pipe 703. Vibration is transmitted to the pickling solution in the pickling and rust removal box 1 through the extended pipe 703. The vibration enhances the contact and penetration between the acid and the rust layer through high-frequency mechanical disturbance, accelerates the peeling of the rust layer and reduces dead corners, while inhibiting excessive corrosion caused by local retention of acid, thus improving the efficiency and uniformity of rust removal. Air is blown into the conduit 3 and the branch pipe 301 by the air pump 5, and a large number of air bubbles are discharged through the air outlet 302. The disturbance and impact force generated when the air bubbles are generated and burst in the acid can enhance the flushing and penetration of the acid on the rust layer, accelerate the peeling of the rust layer and remove the residual rust in dead corners, thus improving the efficiency and cleanliness of rust removal. After the rust removal is completed, the pickling solution is discharged and the steel structure parts can be taken out.
