Description

Technical Field

[0001] This utility model belongs to the field of steel strip electroplating technology, and in particular relates to a degreasing device for steel strip electroplating. Background Technology

[0002] In the field of steel strip electroplating, high-quality degreasing is a key prerequisite for ensuring coating quality. Traditional steel strip degreasing before electroplating presents many challenges. For example, solvent degreasing methods are not only inefficient, but also prone to solvent evaporation, causing environmental pollution and high subsequent processing costs. Some mechanical degreasing methods cause significant damage to the steel strip surface, affecting its mechanical properties. Furthermore, common degreasing devices cannot accurately match the degreasing requirements of steel strips of different specifications, resulting in inconsistent degreasing effects. Therefore, developing an efficient, environmentally friendly degreasing device that can adapt to various steel strip specifications is of great practical significance for improving the quality and production efficiency of steel strip electroplating.

[0003] However, existing degreasing devices for steel strip electroplating are not convenient for stirring the degreasing solution during use. The degreasing solution is prone to stratification and sedimentation during use, which reduces the degreasing effect and affects the quality of steel strip electroplating. Utility Model Content

[0004] The purpose of this utility model is to provide a degreasing device for steel strip electroplating. By setting an anti-sedimentation mechanism, it solves the problem that existing degreasing devices for steel strip electroplating are not easy to stir during use, and the degreasing solution is prone to stratification and sedimentation during use, which reduces the degreasing effect and affects the quality of steel strip electroplating.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a degreasing device for electroplating steel strips, including an outer barrel, on which an anti-settling mechanism and a rinsing and circulation mechanism are provided;

[0007] The outer barrel is hinged with a door. The anti-sedimentation mechanism includes a barrel cover fixedly connected to the inner wall of the outer barrel. A rotating shaft is rotatably connected to the inner wall of the barrel cover, and the rotating shaft passes through the barrel cover. A motor is fixedly connected to the top of the barrel cover. The output shaft of the motor is fixedly connected to the rotating shaft through a coupling. A feed cover is hinged to the top of the barrel cover. A partition is fixedly connected to the inner wall of the outer barrel. The bottom of the rotating shaft is rotatably connected to the partition. The rinsing and circulation mechanism includes a second bracket fixedly connected to the bottom of the partition. The left side of the second bracket is fixedly connected to the outer barrel.

[0008] Furthermore, the inner wall of the outer barrel is rotatably connected to two supports, the inner walls of the two supports are fixedly connected to the rotating shaft, and several scrapers are fixedly connected between the two supports. The outer wall of the rotating shaft is fixedly connected to a stirring paddle, and the bottom of the partition is connected to several discharge pipes, each of which is equipped with an electric valve.

[0009] Furthermore, a bracket three is fixedly connected to the bottom of the partition, and the right side of the bracket three is fixedly connected to the outer barrel. A bracket four is fixedly connected to the bottom of the partition, and two limiting shafts are fixedly connected to the bottom of the bracket four. A cleaning block is rotatably connected to the outer wall of each of the two limiting shafts. A connecting block one is fixedly connected to the bottom of the two limiting shafts. A through groove is opened on the outer barrel, the through groove passes through the outer barrel, the through groove passes through the bracket two, and the through groove passes through the bracket three. A filter plate is fixedly connected to the inner wall of the outer barrel.

[0010] Furthermore, a connecting pipe 1 is connected to the bottom of the outer tub, a water pump is connected to the bottom of the connecting pipe 1, a connecting pipe 2 is connected to the rear side of the water pump, the top of the connecting pipe 2 is connected to the tub lid, a connecting block 2 is fixedly connected to the rear side of the outer tub, the connecting pipe 2 passes through the connecting block 2, and the outer wall of the connecting pipe 2 is fixedly connected to the connecting block 2.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up an anti-sedimentation mechanism, before degreasing, the feed cover can be opened to add the degreasing liquid into the space formed between the bucket cover, partition, and outer bucket. At this time, the motor can be started to rotate its output shaft. When the motor output shaft rotates, it will drive the rotating shaft to rotate. When the rotating shaft rotates, it will drive the stirring paddle to rotate and stir the degreasing liquid to prevent it from settling. When the rotating shaft rotates, it will also drive several scrapers to rotate through two supports to further stir the degreasing liquid and prevent it from stratifying. Then, the discharge pipe can be operated by the electric valve to degrease the steel strip, so that the degreasing liquid in the device can be fully stirred to prevent sedimentation or stratification, thereby ensuring the degreasing effect of the degreasing liquid and thus ensuring the quality of subsequent steel strip electroplating.

[0013] 2. By setting up a flushing and circulation mechanism, during degreasing, the steel belt can be inserted into the outer barrel from the left side of the through groove, then passed sequentially through support two, between the two cleaning blocks, and support three, and finally pulled out of the outer barrel from the right side of the through groove. While the steel belt is passing through the through groove, the electric valve can be activated to discharge the degreasing liquid above the baffle from the discharge pipe, allowing it to briefly stop in support two to flush the steel belt. As the steel belt passes between the two cleaning blocks, the floating grease on the surface of the steel belt will be scraped off, and the floating grease will fall into the filter under the flushing effect of the degreasing liquid sprayed from the two discharge pipes on the right side. Above the plate, when the degreased steel belt passes through support three, the residual degreasing liquid on the steel belt will be scraped off. When the floating grease and degreasing liquid fall onto the filter plate, the degreasing liquid will enter the connecting pipe one through the filter plate. At this time, the water pump can be started to transport the degreasing liquid back to the outer barrel through the connecting pipe two, while the floating grease will remain on the filter plate. Every once in a while, the door can be opened to clean the agitator, so that the floating grease on the steel belt can be scraped off, and the degreasing liquid containing floating grease impurities can be filtered and recycled. This not only ensures the efficiency of steel belt degreasing and cleaning, but also reduces the waste of degreasing liquid.

At this time, the motor 203 can be started to rotate its output shaft. When the output shaft of the motor 203 rotates, it will drive the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, it will drive the stirring paddle 208 to rotate and stir the degreasing liquid to prevent it from settling. When the rotating shaft 202 rotates, it will also drive several scrapers 207 to rotate through the two supports 206 to further stir the degreasing liquid and prevent it from stratifying. Then, the discharge pipe 209 can be operated through the electric valve 210 to degrease the steel belt.
