Description

Technical Field

[0001] This utility model relates to the field of electroplating tank technology, and in particular to a cleaning device for hot-dip galvanizing tanks. Background Technology

[0002] Hot-dip galvanizing is one of the most effective means of delaying environmental corrosion of steel materials. It involves immersing cleaned and activated steel products in molten zinc. Through the reaction and diffusion between iron and zinc, a zinc alloy coating with good adhesion is formed on the surface of the steel products. It is an effective method of metal corrosion protection. The hot-dip galvanizing tank is the place where the workpiece is hot-dip galvanized. The hot-dip galvanizing tank includes a heating chamber and a galvanizing tank. In terms of the materials used, hot-dip galvanizing tanks are usually divided into tanks built with refractory materials and tanks made of steel materials.

[0003] Existing electroplating cleaning devices generally use spray nozzles to directly rinse the plating tanks with water. However, this cleaning method is ineffective, lacks variety, and is difficult to clean thoroughly. It is also difficult to remove highly adhesive impurities, failing to meet the needs of electroplating tank cleaning. Therefore, we propose a hot-dip galvanizing tank cleaning device to solve the above problems.

[0004] Therefore, it is necessary to provide a hot-dip galvanizing tank cleaning device to solve the above-mentioned technical problems. Utility Model Content

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-4This utility model provides a hot-dip galvanizing tank cleaning device, including a hot-dip galvanizing tank body 3 and a support 6. One end of the hot-dip galvanizing tank body 3 has a slot 5, and a cover plate 4 is hinged inside the slot 5. A servo motor 7 is fixed to the side of the support 6. A slide rod 9 slides through the side of the support 6. A rack plate 10 arranged along the length of the slide rod 9 is fixed to the side of the slide rod 9. A gear 8 that meshes with the rack plate 10 is fixed to the output end of the servo motor 7. A connecting assembly 2 is connected to the side of the support 6. A connector plate 14 is fixed to one end of the slide bar 9, which can be inserted into the hot-dip galvanizing tank 3 through the slot 5. Cleaning bristles 15 are densely distributed on the edge side of the connector plate 14 and contact the inner wall of the hot-dip galvanizing tank 3. A connecting rod 16 is fixed to the end of the connector plate 14 away from the slide bar 9. A pre-washing component 1 is provided on the end of the connecting rod 16 away from the connector plate 14. When cleaning the inside of the hot-dip galvanizing tank 3, first move the support 6 to the slot 5, open the slot 5, and align the connector plate 14 with the slot. 5. Start the servo motor 7 to work. The output end of the servo motor 7 drives the gear 8 to rotate, thereby driving the slide bar 9 to move through the cooperation of the gear 8 and the rack plate 10. The slide bar 9 drives the joint plate 14 and the pre-washing component 1 to move inside the hot-dip galvanizing tank 3. The pre-washing component 1 sprays the cleaning water evenly and finely onto the inner walls of the hot-dip galvanizing tank 3, thereby giving a comprehensive preliminary rinse to the impurities adhering to the inner walls of the hot-dip galvanizing tank 3, and performing pre-cleaning. This washes away some of the impurities and reduces the adhesion of the impurities remaining on the inner walls of the hot-dip galvanizing tank 3. After the impurities have been pre-cleaned, the cleaning brush bristles 15 on the edge of the joint plate 14 further brush and clean the inner walls of the hot-dip galvanizing tank 3, thereby thoroughly cleaning the impurities adhering to the inner walls of the hot-dip galvanizing tank 3. The cleaning is comprehensive. The step-by-step cleaning method effectively ensures the cleaning effect while reducing the wear of the cleaning components and extending the service life of the cleaning components.

[0025] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the pre-wash assembly 1 includes a cleaning plate 101 fixed to the end of the connecting rod 16 away from the connector plate 14. The cleaning plate 101 has a cavity 102 inside. The slide rod 9 has a water inlet channel 104 communicating with the cavity 102 inside. A water supply hose 105 communicating with the water inlet channel 104 is fixed to the end of the slide rod 9 away from the connector plate 14. Multiple water spray holes 103 communicating with the cavity 102 are provided on the edge side of the cleaning plate 101. These multiple water spray holes 103 are evenly distributed. (Specific details omitted). During operation, the water supply hose 105 is connected to a high-pressure water source, and the cleaning plate 101 is set in front of the connector plate 14. The cleaning water is delivered to the cavity 102 through the water supply hose 105 and the water inlet channel 104. The cleaning water is then sprayed evenly and finely onto the inner walls of the hot-dip galvanizing tank 3 around the perimeter and the inner wall of the bottom through multiple equally spaced water spray holes 103. This process thoroughly and initially washes away the impurities adhering to the inner wall of the hot-dip galvanizing tank 3, performing pre-cleaning and washing away some of the impurities while reducing the adhesion of the impurities remaining on the inner wall of the hot-dip galvanizing tank 3.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that the connecting component 2 includes a support plate 201 fixed to the side of the support 6. A bolt 202 is threadedly connected to the end of the support plate 201 away from the support 6. A threaded hole adapted to the thread of the bolt 202 is opened on the outer wall of the hot-dip galvanizing tank 3. In actual operation, by screwing the bolt 202 on the end of the support plate 201 into the threaded hole on the outer wall of the hot-dip galvanizing tank 3, the support 6 and the hot-dip galvanizing tank 3 are fixed as one unit, ensuring the smooth movement of the slide bar 9, thereby enabling a comprehensive cleaning of the inside of the hot-dip galvanizing tank 3.

[0027] Further as Figure 1 As shown, it is worth noting that a base plate 11 is fixed to the bottom of the support 6, and multiple symmetrically distributed support legs 12 are fixed to the bottom side of the base plate 11. Casters 13 are installed on the bottom of the support legs 12. In actual operation, after the inside of the hot-dip galvanizing tank 3 is cleaned, the bolts 202 are removed to contact the support plate 201 and the hot-dip galvanizing tank 3. The support 6 can be moved easily by the casters 13, which facilitates transfer and storage. The cover plate 4 is then placed inside the tank opening 5 to seal the inside of the hot-dip galvanizing tank 3.

[0028] This solution includes the following working process: When cleaning the inside of the hot-dip galvanizing tank 3, first move the support 6 to the opening 5, open the opening 5, align the connector plate 14 with the opening 5, and the output end of the servo motor 7 drives the gear 8 to rotate. This, in turn, through the cooperation of the gear 8 and the rack plate 10, drives the slide rod 9 to move. The slide rod 9 then drives the connector plate 14 and the cleaning plate 101 to move inside the hot-dip galvanizing tank 3. The cleaning plate 101 is positioned in front of the connector plate 14. Cleaning water is delivered to the cavity 102 through the water hose 105 and the water inlet channel 104. Then, through multiple evenly distributed spray holes 103, the cleaning water is sprayed evenly and finely onto the inner walls of the hot-dip galvanizing tank 3 on all four sides and the inner wall of the bottom. The impurities adhering to the inner wall of the hot-dip galvanizing tank 3 are thoroughly rinsed and pre-cleaned. This process washes away some of the impurities and reduces their adhesion to the inner wall of the hot-dip galvanizing tank 3. After the pre-cleaning, the inner wall of the hot-dip galvanizing tank 3 is further cleaned by brushing with the cleaning bristles 15 on the side edge of the joint plate 14. This thoroughly cleans the impurities adhering to the inner walls around and at the bottom of the hot-dip galvanizing tank 3. The bolts 202 at the end of the support plate 201 are screwed into the threaded holes on the outer wall of the hot-dip galvanizing tank 3, thus fixing the support 6 and the hot-dip galvanizing tank 3 together and ensuring the smooth movement of the slide rod 9. This allows for a comprehensive cleaning of the inside of the hot-dip galvanizing tank 3.

[0029] Further as Figure 1 As shown, it is worth noting that the inner side of the bottom of the hot-dip galvanizing tank 3 is set as an inclined surface with the lower end of the inclined surface facing the tank opening 5. In actual operation, the inclined inner side of the bottom of the hot-dip galvanizing tank 3 allows the cleaning water carrying impurities to be automatically discharged through the tank opening 5, eliminating the need for manual removal of impurities and effectively improving the convenience of cleaning.

[0030] Further as Figure 1 and Figure 2 As shown, it is worth noting that a handle can be fixed to the side of the support 6, and a rubber sleeve is fitted on the surface of the handle; during operation, the handle allows the support 6 to be easily pushed by hand, making operation convenient.

[0031] In summary: the pre-washing component 1 sprays cleaning water evenly and finely onto the inner walls of the hot-dip galvanizing tank 3, thereby thoroughly rinsing away impurities adhering to the inner walls of the hot-dip galvanizing tank 3 and performing pre-cleaning. This washes away some impurities and reduces the adhesion of impurities remaining on the inner walls of the hot-dip galvanizing tank 3. After pre-cleaning, the cleaning brushes 15 on the side edges of the connector plate 14 further clean the inner walls of the hot-dip galvanizing tank 3, thus thoroughly cleaning the impurities adhering to the inner walls of the hot-dip galvanizing tank 3. The step-by-step cleaning method effectively ensures the cleaning effect while reducing the wear of the cleaning components and extending their service life. By screwing the bolts 202 on the end of the support plate 201 into the threaded holes on the outer wall of the hot-dip galvanizing tank 3, the support 6 and the hot-dip galvanizing tank 3 are fixed together, ensuring the smooth movement of the slide rod 9, thereby enabling a comprehensive cleaning of the inside of the hot-dip galvanizing tank 3.

[0032] The servo motor 7 can be purchased from the market. The servo motor 7 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
