Description

Technical Field

[0001] This utility model belongs to the field of cold-rolled strip steel processing technology, specifically relating to a galvanizing device for cold-rolled strip steel. Background Technology

[0002] Cold-rolled strip steel is a widely used metal material, usually made of carbon steel or stainless steel. During the processing of cold-rolled strip steel, galvanizing equipment is required. Galvanizing of cold-rolled strip steel is a surface treatment process aimed at improving the corrosion resistance, wear resistance and aesthetics of the strip steel.

[0003] For example, patent CN219364996U discloses a cold-rolled strip galvanizing device, including a feeding mechanism, a galvanizing tank, a cooling mechanism, guide rollers, and traction rollers. The feeding mechanism is located on one side of the galvanizing tank, and the cooling mechanism is located above the galvanizing tank. The feeding mechanism includes a feeding box and a strip feeding channel. Multiple feeding rollers are installed inside the feeding box, and the strip feeding channel is integrally connected to one side of the feeding box. One end of the strip feeding channel extends into the galvanizing tank. The galvanizing tank is located on one side of the feeding box, and a zinc bath is provided inside the galvanizing tank. A submerged roller, a deflecting roller A, and a deflecting roller B are installed in the galvanizing tank. Deflecting roller A is located above the submerged roller, and deflecting roller B is located above deflecting roller A. The cooling mechanism includes a cooling chamber A and a cooling chamber B.

[0004] The aforementioned cold-rolled strip galvanizing equipment does not have a cleaning structure for the cold-rolled strip before it comes into contact with the galvanizing bath. When there are impurities such as oil, dust, or iron powder on the surface of the cold-rolled strip, they may hinder the good bonding between the zinc liquid and the strip surface when the strip comes into contact with the galvanizing bath, thus affecting the galvanizing quality. Furthermore, if the strip is not pre-cleaned, it may contaminate the zinc liquid in the galvanizing bath. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model relates to a cold-rolled strip steel that is guided by multiple sets of feed rollers and floats freely in the processing rack, connecting rack, and galvanizing tank. When the strip steel enters the processing rack, the operator needs to start the motor in advance. Under the guidance of two synchronous pulleys and a synchronous belt, the motor can rotate two rotating rods and the cleaning brushes installed around them. Since the two cleaning brushes are located on both sides of a section of the strip steel, both sides of the strip steel can be cleaned during transportation. Then, the operator starts the water pump, which, guided by the first and second connecting pipes at both ends, can transport the water in the water collection area below the processing rack to the diversion pipe and spray it out through the spray head on the opposite side of the pipe. This allows for a secondary cleaning operation on both sides of the cold-rolled strip steel that has already been cleaned. Since a filter rack is installed between the water collection area and the first connecting pipe, the cleaning water can be recycled.

[0019] After cleaning, the cold-rolled strip steel of this utility model passes through a connecting frame. Personnel can pre-open the fan assembly and heating rod inside the staggered side mounting frames on both sides of the connecting frame. At this time, the air will be heated by the heating rod and guided to the air slot by the air distribution pipe and sprayed out, thereby drying the strip steel that has just been cleaned, providing a good foundation for the subsequent galvanizing of the strip steel into the galvanizing bath. Personnel can then use the material changing mechanism to replace the zinc liquid in the galvanizing bath, which is portable and practical. Attached Figure Description

The second cleaning assembly 62 includes a filter frame 621, and the filter frame 621 is installed on the inner side below the processing frame 1. One end of the filter frame 621 is connected to a first connecting... A pipe 622 is connected to a water pump 623 at one end, and a second pipe 624 is connected to the other end of the water pump 623. A diversion pipe 625 is connected to the end of the second pipe 624. Spray heads 626 are provided on opposite inner surfaces of the diversion pipe 625 at equal intervals along opposite inner surfaces. The cold-rolled strip 4 is guided by multiple sets of feed rollers 5 and moves freely in the processing rack 1, the connecting rack 2, and the galvanizing tank 3. When the strip 4 enters the processing rack 1, the operator needs to start the motor 612 in advance. Under the guidance of two synchronous pulleys 613 and a synchronous belt 614, it can carry two rotating... The rod 611 and the cleaning brushes 615 around it rotate.

After cleaning, the cold-rolled strip steel 4 will pass through the connecting frame 2. Personnel can pre-open the fan assembly 75 and heating rod 73 inside the side mounting frame 71 on both sides of the connecting frame 2. At this time, the air will be heated by the heating rod 73 and guided to the air channel 77 by the air distribution pipe 76 and sprayed out. This will dry the strip steel 4 that has just been cleaned, providing a good foundation for the strip steel 4 to enter the galvanizing tank 3 for galvanizing. Personnel can then use the material changing mechanism 8 to replace the zinc liquid in the galvanizing tank 3. It is portable and practical.

[0031] Working principle: Cold-rolled strip steel 4 is guided by multiple sets of feed rollers 5 and floats in the processing rack 1, connecting rack 2, and galvanizing tank 3. When the strip steel 4 enters the processing rack 1, the operator needs to start the motor 612 in advance. Under the guidance of two synchronous pulleys 613 and a synchronous belt 614, it can rotate two rotating rods 611 and the cleaning brushes 615 set around them. Since the two cleaning brushes 615 are set on both sides of a section of the strip steel 4, the two sides of the strip steel 4 can be cleaned during transportation. Then, the operator starts the water pump 623. Under the guidance of the first connecting pipe 622 and the second connecting pipe 624 at both ends, the water in the water collection area at the bottom of the processing rack 1 can be transported to the diversion pipe 625 and then through the spray head 626 on the opposite side of the pipe. The water is sprayed out, allowing for a secondary cleaning of both sides of the cleaned cold-rolled strip steel 4. Since a filter frame 621 is installed between the water collection area and the first connecting pipe 622, the cleaning water can be recycled. After cleaning, the cold-rolled strip steel 4 passes through the connecting frame 2. Personnel can pre-open the fan assembly 75 and heating rod 73 inside the side mounting frames 71 that are staggered on both sides of the connecting frame 2. At this time, the air will be heated by the heating rod 73 and guided to the air slot 77 by the air distribution pipe 76, thus drying the cleaned strip steel 4 and providing a good foundation for the subsequent galvanizing of the strip steel 4 into the galvanizing bath 3. Personnel can then use the material changing mechanism 8 to replace the zinc liquid in the galvanizing bath 3, which is portable and practical.
