Description

Technical Field

[0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metal, alloy or other materials for aesthetics and rust prevention. The main method used is hot-dip galvanizing.

[0003] Zinc is easily soluble in acid and alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. It is mainly used to prevent steel from corrosion, and its protective performance is closely related to the thickness of the coating. The zinc coating can significantly improve its protective and decorative properties after passivation, dyeing or coating with a light protectant.

[0004] However, when the existing galvanizing equipment is galvanizing, after a period of processing time, a thin film will form on the top of the liquid in the zinc pool due to contact with the air, and impurities such as dust carried by the workpiece may adhere to it. At this time, it is usually necessary to manually clean it with the help of certain tools. This manual cleaning method is extremely troublesome and requires manual cleaning at regular intervals, which greatly delays processing efficiency.

[0056] The working principle of the automobile sheet metal surface galvanizing equipment with filtering function provided by the present invention is as follows:

[0057] When the automobile sheet metal parts are galvanized, the automobile sheet metal parts are respectively mounted on a plurality of mounting rods 13 through hooks, and then the first motor 11 is started to drive the threaded rod 18 to rotate, thereby driving the sliding frame 7 to move, and the sliding frame 7 drives the hydraulic rod 30 and the automobile sheet metal parts mounted on the mounting device to move synchronously to the top of the zinc pool box 9, and then the hydraulic rod 30 is started to lower the automobile sheet metal parts into the zinc water pool 14 for galvanizing;

[0058] After the automobile sheet metal parts have been galvanized for a period of time, the second motor 24 is started, and the second motor 24 drives the gear 19 to rotate along the tooth groove 20, thereby driving the filter frame 23 to move horizontally along the first direction, so that the filter frame 23 scrapes off the debris on the inner wall surface of the zinc water pool 14; after the liquid in the zinc water pool 14 enters the filter frame 23, the impurities contained in the liquid are filtered out through the filtering function of the filter plate 22, and the filtered zinc water can be smoothly discharged through the filter holes of the filter plate 22, returned to the zinc water pool 14 or for subsequent processing, and the filtered impurities are collected in the filter frame 23.

[0059] When there are too many impurities in the zinc water pool 14 and the zinc water in the zinc pool is used up, the first cleaning plate 26 can be removed to clean the filter plate 22 and the filter frame 23 from impurities.

[0060] Compared with the related art, the automobile sheet metal surface galvanizing equipment with filtering function provided by the present invention has the following beneficial effects:

[0061] The second motor 24 drives the rotating shaft to drive the gear 19 to rotate, thereby driving the filter frame 23 to move horizontally along the inside of the tooth groove 20, so that the filter frame 23 scrapes off the condensation, dust and other debris on the inner wall of the zinc water pool 14, and filters out the debris through the filter holes in the filter plate 22. At the same time, the filtered zinc water is discharged through the filter holes, so that the galvanizing equipment has a good filtering function, so that personnel do not need to clean the zinc pool regularly, and the processing efficiency of the galvanizing equipment is effectively improved.

[0062] The second motor 24 of the walking device is controlled by the control system. The walking device is combined with the automatic control system. The walking device can realize that the filter device automatically cleans and filters the zinc water pool according to a preset program. This avoids the tediousness and time-consuming of manual cleaning and improves the cleaning efficiency. Moreover, since the filter device can be moved, it can cover more areas of the zinc water pool to ensure that condensation, dust and other debris on the inner wall of the zinc water pool are fully removed. This helps to maintain the cleanliness of the zinc water pool and extend its service life. The movable filter device can continuously scrape off the debris on the inner wall of the zinc water pool during the movement and filter it through the filter holes on the filter plate. This dynamic filtering method can more effectively remove impurities in the zinc water and improve the quality of the zinc water. The movable filter device can be moved to a suitable position as needed to adapt to zinc water pools of different sizes and different galvanizing process requirements.

[0063] Embodiment 2

[0064] Please refer to Figure 5 Based on the automobile sheet metal surface galvanizing equipment with filtering function provided in the first embodiment of the present application, the second embodiment of the present application proposes another automobile sheet metal surface galvanizing equipment with filtering function. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0065] Specifically, the difference of the automobile sheet metal surface galvanizing equipment with filtering function provided in Example 2 of the present application is that two fixing rods 28 are fixedly connected to the top of the filter frame 23, and the tops of the two fixing rods 28 are fixedly connected to the second cleaning plate 29, and the second cleaning plate 29 is used to touch the automobile sheet metal to make excess zinc water adhered to the surface of the automobile sheet metal drip off.

[0066] Compared with the related art, the automobile sheet metal surface galvanizing equipment with filtering function provided by the present invention has the following beneficial effects:

[0067] By arranging two fixing rods 28 inside the filter frame 23 and arranging a second cleaning plate 29 on the top of the fixing rods 28, when the sheet metal is galvanized, the hanging sheet metal is touched by the movable second cleaning plate 29, so that the uncondensed zinc water drips, avoiding the waste of zinc water and dripping to the outside of the box, and effectively saving the resources of zinc materials.

[0068] The movable filter device drives the cleaning device to move synchronously, and the automated cleaning device reduces the need for direct manual participation in the galvanizing process. This helps reduce the labor intensity of workers, improve the working environment, and increase workers' job satisfaction. The excess zinc water removed by the cleaning device is returned for reuse, which helps reduce the discharge and waste of zinc water. It also helps to avoid uneven deposition of zinc water on the surface of sheet metal parts, and improves the uniformity and aesthetics of the galvanized layer. The integrated design of the cleaning device and the filtering device helps to optimize the space utilization of the galvanizing equipment. This makes the equipment more compact and reduces the floor space.

[0069] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
