Description

Technical Field

[0001] This utility model relates to the technical field of welded pipe production equipment, and in particular to a steel strip cleaning device. Background Technology

[0002] In welded pipe production, steel strip is typically bent into a circular tube of a set size using a forming device, and then the weld seam is joined together to obtain the steel pipe. Current welded pipe production processes generally involve: placing the steel strip on an uncoiling rack, which then transports it to forming equipment for shaping; next, a welding device welds the shaped steel strip into a tubular structure; followed by polishing, heat treatment, sizing and straightening, eddy current testing, cutting, and length measurement; finally, the finished product is packaged.

[0003] However, during the processing of steel strip, after high-frequency quenching, drawing and other processes, dust and oil will adhere to the surface of the steel strip. When the steel strip is directly formed and then welded, it is easy to cause welding defects such as porosity, inclusions and cracks in the weld, thereby affecting the strength and quality of the welded pipe and reducing its service life. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a steel strip cleaning device that can improve the cleanliness of the steel strip surface, ensure the strength and welding quality of the welded pipe, and extend the service life of the welded pipe.

[0005] A steel strip cleaning device according to an embodiment of the present invention includes: a cleaning tank disposed between an unwinding frame and a forming device for holding cleaning fluid, with an inlet on one side and an outlet on the other side; a plurality of guide rollers disposed inside the cleaning tank, with the steel strip sequentially wound around the plurality of guide rollers along the conveying direction, the plurality of guide rollers being used to sink and immerse the steel strip in the cleaning fluid; a heating mechanism including a heater disposed on the bottom wall of the cleaning tank, the heater being used to heat the cleaning fluid; and a cleaning mechanism including an ultrasonic transducer and an ultrasonic generator, the ultrasonic transducer being disposed on the side wall of the cleaning tank, the ultrasonic transducer being connected to the ultrasonic generator.

[0006] A steel strip cleaning device according to an embodiment of the present utility model has at least the following beneficial effects:

[0007] 1. This utility model, by setting up a cleaning tank and a heater, has an inlet and an outlet on both sides of the cleaning tank. Several guide rollers are installed inside the cleaning tank. The steel strip enters the cleaning tank through the inlet and then passes around the guide rollers in sequence, causing the steel strip to sink and be immersed in the cleaning solution. The heater heats the cleaning solution, which removes oil stains adhering to the surface of the steel strip. The cleaned steel strip is output from the outlet to the forming device. Thus, the cleanliness of the steel strip surface can be improved, ensuring the strength and welding quality of the welded pipe and extending the service life of the welded pipe.

[0008] 2. This utility model incorporates an ultrasonic transducer and an ultrasonic generator. The ultrasonic generator converts the acoustic energy of the high-power ultrasonic frequency source into the mechanical vibration of the ultrasonic transducer. The ultrasonic waves are radiated through the cleaning chamber wall onto the cleaning liquid inside the cleaning chamber, causing the microbubbles in the cleaning liquid to vibrate under the action of the sound waves. This disrupts the adhesion between the dirt and the steel strip surface, causing fatigue damage to the dirt layer and resulting in its removal. The vibration of the gas bubbles scrubs the surface of the steel strip, thereby further improving the cleanliness of the steel strip surface.

[0009] According to some embodiments of the present invention, the heating mechanism further includes a temperature sensor and a temperature controller. The temperature sensor is used to detect the temperature of the cleaning fluid, and the temperature controller is connected to the heater and the temperature sensor respectively.

[0010] The advantages are: by setting up a temperature sensor and a temperature controller, the temperature sensor can detect the temperature in the cleaning tank in real time, and the temperature controller can receive the temperature signal from the temperature sensor and control the real-time output power of the heater through the temperature signal. Thus, the temperature of the cleaning solution can be accurately controlled, ensuring the stability of the process conditions.

[0011] According to some embodiments of this utility model, a control box is provided on the outside of the cleaning box, and the ultrasonic generator and the temperature controller are located inside the control box.

[0012] The advantages are: by setting up a control box, the ultrasonic generator and temperature controller are housed inside the control box, which can protect the ultrasonic generator and temperature controller, and also makes it easy for operators to adjust the parameters.

[0013] According to some embodiments of the present invention, a support is provided at the bottom of the cleaning tank, a drain hole is provided on the bottom wall of the cleaning tank, the drain hole is connected to a drain pipe, a drain valve is provided on the drain pipe, and a water receiving tank is provided below the cleaning tank.

[0014] The advantages are: by setting up a bracket, drain hole, drain pipe, drain valve and water tank, the bracket can support the cleaning tank. After cleaning for a period of time, the cleaning fluid will contain a lot of impurities. At this time, the drain valve can be opened to drain the cleaning fluid from the drain pipe into the water tank. Then, the drain valve can be closed and the cleaning fluid can be added again. This makes it easy to drain the dirtier cleaning fluid in time and prevent the cleaning fluid from causing secondary pollution to the steel strip.

[0015] According to some embodiments of the present invention, the water receiving tank is equipped with a filter, which is used to filter impurities in the discharged cleaning fluid.

[0016] The advantage is that by installing a filter, when the cleaning fluid is discharged from the drain pipe to the water tank, the filter can filter out the impurities in the cleaning fluid. The filtered cleaning fluid flows into the water tank, thus allowing the cleaning fluid to be reused, improving the utilization rate of the cleaning fluid and reducing production costs.

[0017] According to some embodiments of this utility model, a water pump is provided inside the water receiving tank, a water inlet pipe is provided on the top of the cleaning tank, and the output end of the water pump is connected to the water inlet pipe.

[0018] The advantage is that by setting up a water pump and an inlet pipe, the water pump delivers the filtered cleaning solution from the inlet pipe to the cleaning tank, thus allowing the cleaning solution to be recycled. This avoids operators manually transferring the cleaning solution from the water tank to the cleaning tank, reducing labor intensity.

[0019] According to some embodiments of the present invention, the discharge port is provided with a scraper blade, which is used to scrape away the cleaning fluid adhering to the surface of the steel strip.

[0020] The advantage is that by setting up a scraper, the scraper can remove the cleaning fluid adhering to the surface of the steel strip, thereby ensuring that the surface of the steel strip is clean and guaranteeing the strength and welding quality of the welded pipe.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] The cleaning tank 100 is located between the unwinding frame and the forming device and is used to carry the cleaning fluid. It has an inlet 110 on one side and an outlet 120 on the other side. Several guide rollers 130 are installed inside the cleaning tank 100. The steel strip is wound around the guide rollers 130 in sequence along the conveying direction. The guide rollers 130 are used to sink the steel strip and immerse it in the cleaning fluid.

[0032] Functionally, the heating mechanism 140 is used to heat the cleaning fluid, and includes a heater 150, which is disposed on the bottom wall of the cleaning tank.

[0033] Furthermore, the cleaning mechanism 160 includes an ultrasonic transducer 170 and an ultrasonic generator 180. The ultrasonic transducer 170 is disposed on the side wall of the cleaning tank 100, and the ultrasonic transducer 170 is connected to the ultrasonic generator 180.

[0034] Specifically, the steel strip enters the cleaning tank 100 through the feed inlet 110, and then passes around several guide rollers 130 in sequence, causing the steel strip to sink and immerse itself in the cleaning solution. The heater 150 heats the cleaning solution, which removes oil stains adhering to the surface of the steel strip. At the same time, the ultrasonic generator 180 converts the acoustic energy of the power ultrasonic frequency source into the mechanical vibration of the ultrasonic transducer 170, which radiates the ultrasonic waves through the wall of the cleaning tank 100 into the cleaning solution inside the cleaning tank 100. This causes the microbubbles in the cleaning solution to vibrate under the action of the sound waves, which can break the adsorption of dirt to the surface of the steel strip, causing fatigue damage to the dirt layer and removing it. The vibration of the gas bubbles scrubs the surface of the steel strip. The cleaned steel strip is output from the discharge port 120 to the forming device. Thus, the cleanliness of the steel strip surface can be improved, ensuring the strength and welding quality of the welded pipe and extending the service life of the welded pipe.

After cleaning for a period of time, the cleaning fluid contains a lot of impurities. At this time, the drain valve 250 is opened to drain the cleaning fluid from the drain pipe 240 into the water tank 260. Then, the drain valve 250 is closed and the cleaning fluid is added again.
