Description

Technical Field

[0001] The present application relates to the technical field of metal material plating, and in particular to a surface anti-corrosion treatment device for metal materials. Background Art

[0002] Hot-dip galvanizing is one of the most effective means to delay environmental corrosion of steel materials. It involves immersing the cleaned and activated steel products in molten zinc liquid, and coating the surface of the steel products with a zinc alloy coating with good adhesion through the reaction and diffusion between iron and zinc. Compared with other metal protection methods, the hot-dip galvanizing process has incomparable advantages in the protection characteristics of the combination of the physical barrier and electrochemical protection of the coating, the bonding strength between the coating and the substrate, the density, durability, maintenance-freeness and economy of the coating, and its adaptability to the shape and size of the product.

[0003] The zinc liquid in the hot-dip galvanizing tank must be maintained at around 450℃-500℃ to complete the galvanizing of the workpiece. Due to the temperature difference between the inside of the zinc liquid and the upper surface of the zinc liquid when it comes into contact with the air, a zinc film is easily formed on the upper surface of the zinc liquid. Therefore, when the workpiece is taken out of the zinc liquid, the zinc film is easy to adhere to the surface of the workpiece, thus affecting the galvanizing quality of the workpiece.

[0004] The specification of Chinese patent CN202320924910.3 discloses a hot-dip galvanizing tank for hot-dip galvanizing production, including a galvanizing tank, a cleaning component is vertically installed on the top of the galvanizing tank, and the cleaning component includes a slide rail, a slider, a threaded rod, a cross plate, a curved arm, and a metal scraper; the slider is slidably distributed on the top of the slide rail, the threaded rod is distributed inside the slide rail, the cross plate is vertically fixed to the top of the slider, and a curved arm is vertically distributed on the bottom of the cross plate, the top of the curved arm is vertically fixed to the bottom of the cross plate, and the metal scraper is vertically fixed to the bottom of the curved arm. This patent sets a cleaning component and adopts a guide rail structure to drive the metal scraper to remove the zinc film on the surface of the solution.

[0039] See also Figure 1 and Figure 2 The present application discloses a surface anticorrosion treatment device for metal materials, including a galvanizing tank 1, a pair of non-adjacent inner walls of the galvanizing tank 1 are respectively provided with a ball groove 101 and a ball outlet groove 102, the interior of the ball groove 101 is fixedly connected with an inclined net 2, the outer end of the galvanizing tank 1 is fixedly connected with a pair of motors 4, the output ends of the pair of motors 4 are both movable through the outer end of the galvanizing tank 1, and are respectively fixedly connected with a ball plate 31 and a volleyball plate 32, the ball plate 31 is located inside the galvanizing tank 1 and at the lower side of the notch of the ball groove 101, and the volleyball plate 32 is located inside the ball outlet groove 102, please refer to Figure 3 and Figure 4 A pair of transfer channels 103 are also provided inside the galvanizing tank 1. The pair of transfer channels 103 are located on both sides of the ball groove 101, and are connected to the ball groove 101 and the ball outlet groove 102. The ball groove 101, the ball outlet groove 102 and the transfer channels 103 are filled with a plurality of mucosal balls 8. Figure 7 , the present application can realize the transfer and removal of the zinc film on the surface of the zinc liquid through the mucosal ball 8;

[0040] Combination Figure 3 and Figure 5 A liquid storage tank 104 is provided on the lower inner wall of the ball-injecting tank 101, and the interior of the liquid storage tank 104 is filled with clean ball liquid. A liquid collecting tank 105 is provided on the upper inner wall of the ball-injecting tank 101, and a liquid pump unit is fixedly connected to the outer end of the galvanizing tank 1, and the liquid pump unit is used to realize the circulation of clean ball liquid between the ball outlet tank 102, the liquid storage tank 104 and the liquid collecting tank 105.

[0041] See also Figure 6The goal plate 31 and the volleyball plate 32 are both composed of a rotating rod 301 and a mesh plate 302. The mesh plate 302 is fixedly connected to the outer end of the rotating rod 301. One end of the rotating rod 301 is fixedly connected to the output end of the motor 4. The goal plate 31 is used to pick up the mucosal balls 8 floating on the surface of the zinc liquid and guide them to roll into the goal groove 101. The volleyball plate 32 is used to pick up the mucosal balls 8 inside the ball outlet groove 102 and guide them to roll out of the ball outlet groove 102, floating on the surface of the zinc liquid. The mesh plate 302 with a mesh structure can allow the zinc liquid to pass through, so that it is not easy to drive the zinc liquid into the goal groove 101 during the process of picking up the mucosal balls 8 on the surface of the zinc liquid.

[0042] See also Fig. 9 The mucosal ball 8 includes a float 81, and a plurality of evenly distributed soft brushes 82 are fixedly connected to the outer end of the float 81. The diameters of the slots of the ball entry groove 101 and the ball exit groove 102 are larger than the diameter of the float 81. The float 81 is made of a material with a density smaller than that of zinc and a melting point greater than 550°C, such as metal aluminum, so that the float 81 can be used normally in high-temperature zinc liquid and float on the surface of the zinc liquid to achieve adhesion and transfer of the zinc film. The soft brush 82 is made of a high-temperature resistant inorganic fiber material and can be used normally in high-temperature zinc liquid and also play a role in adhering to the zinc film.

[0043] See also Figure 2 and Figure 5 The liquid pump unit includes a water pump 51 fixedly connected to the outer end of the galvanizing tank 1, a liquid inlet pipe 52 fixedly connected to the water inlet end of the water pump 51, an end of the liquid inlet pipe 52 fixedly penetrates the outer end of the galvanizing tank 1 and communicates with the liquid storage tank 104, a liquid outlet pipe 53 fixedly connected to the water inlet end of the water pump 51, a plurality of evenly distributed shunt pipes 54 fixedly connected to the upper end of the liquid outlet pipe 53, an end of the shunt pipe 54 fixedly penetrates the outer end of the galvanizing tank 1 and communicates with the liquid collecting tank 105. When in use, the water pump 51 is started, the clean ball liquid in the liquid storage tank 104 is sucked out through the liquid inlet pipe 52, and the clean ball liquid is dispersed and sprayed into the liquid collecting tank 105 through the liquid outlet pipe 53 and the shunt pipe 54 in turn, so that the clean ball liquid flows from top to bottom onto the mucosal ball 8 in the ball tank 101, and the zinc film adhered to the surface of the mucosal ball 8 is washed, so that the surface of the mucosal ball 8 is restored to a certain degree of cleanliness, so that it is convenient to re-enter the zinc liquid to achieve adhesion and transfer of the zinc film again. Please refer to Figure 8 The inner wall of the liquid collecting tank 105 is fixedly connected with a mesh 9, which is located at the lower side of the end of the shunt pipe 54. The mesh 9 has a shunt effect on the clean ball liquid flowing out of the shunt pipe 54, so that the clean ball liquid flows downward in a dispersed and uniform manner.

[0044] See also Figure 5The inclined net 2 is tilted downward in the direction away from the goal plate 31, so that the mucosal ball 8 entering the goal groove 101 is not easily moved out of its groove again. The inclined net 2 is in a non-contact state with the inner wall of the goal groove 101, and the gap distance between the two is smaller than the diameter of the float 81. Through this gap, on the one hand, the clean ball liquid with zinc film flows smoothly downward to the liquid storage tank 104 and is not easy to stay at the upper end of the inclined net 2. On the other hand, the gap does not allow the mucosal ball 8 to pass through, so that the mucosal ball 8 at the upper end of the inclined net 2 smoothly enters the transfer channel 103 on both sides, and then enters the ball outlet groove 102, and is driven into the zinc liquid again by the volleyball plate 32.

[0045] See also Figure 3 and Figure 4 The inner wall of the liquid storage tank 104 is fixedly connected with a recovery pipe 6 communicating with the outside world, and the inner wall of the ball outlet tank 102 is fixedly connected with a drainage pipe 7 communicating with the outside world. The outer ends of the recovery pipe 6 and the drainage pipe 7 are fixedly connected with pipe covers. After the use of this application is completed, the clean ball liquid containing the zinc film can be discharged through the recovery pipe 6 for subsequent treatment; because the mucosal balls 8 will enter the ball tank 101 and be rinsed by the clean ball liquid, and then enter the transfer channel 103, there will be a small amount of clean ball liquid in the transfer channel 103 and the ball outlet tank 102, and the clean ball liquid remaining in the two can be discharged and processed through the drainage pipe 7.

[0046] See also Figure 3 and Figure 4 The inner bottom surface of the inclined net 2 is higher than the inner bottom surface of the transfer channel 103, and the inner bottom surfaces of the ball outlet groove 102 and the transfer channel 103 are located on the same horizontal plane, which facilitates the mucosal balls 8 at the upper end of the inclined net 2 to enter the transfer channel 103 and the ball outlet groove 102 in turn. The notch of the ball outlet groove 102 is located on the upper side of the goal plate 31.

[0047] When in use, the zinc liquid level in the galvanizing tank 1 is controlled at the area located on the upper side of the goal plate 31 and the lower side of the goal groove 101 and the ball outlet groove 102, and the water pump 51 is started at the same time to make the clean ball liquid flow downward from the liquid collecting tank 105. On the one hand, the mucous membrane balls 8 on the surface of the zinc liquid are not easy to enter the goal groove 101 and the ball outlet groove 102 without external force, which plays an adhesion role on the zinc film. On the other hand, Fig.10As shown, the mucosal ball 8 on the upper side is scooped up by the rotation of the goal plate 31, and the scooped mucosal ball 8 with zinc film adhered thereto is squeezed and moved into the goal groove 101 to be flushed with the clean ball liquid, thereby effectively cleaning the zinc film on its surface. At the same time, the flushed mucosal ball 8 in the goal groove 101 moves to the transfer channel 103 under the squeezing force, and then enters the ball outlet groove 102. The clean mucosal ball 8 in the ball outlet groove 102 is driven into the galvanizing tank 1 by the rotation of the volleyball plate 32 to replenish the mucosal ball 8 on the surface of the zinc liquid. Through the recycling of the mucosal balls 8, the zinc film can be continuously transferred, so that the transferred zinc film floats on the liquid surface of the clean ball liquid in the storage tank 104, and the zinc film is removed from the galvanizing tank 1 by discharging the clean ball liquid.

[0048] See also Fig.10 and Fig.11 In the horizontal state, the distance between the volleyball plate 32 and the inner wall of the ball outlet groove 102 is smaller than the diameter of the float 81, so that the volleyball plate 32 can smoothly rotate back and forth by nearly 180° in the ball outlet groove 102, thereby taking multiple mucosal balls 8 out of the ball outlet groove 102 and allowing them to enter the zinc liquid.

[0049] The present application places a plurality of free-floating mucosal balls 8 on the surface of the zinc liquid to adhere the zinc film on the surface of the zinc liquid. At the same time, through the provided goal plate 31 and volleyball plate 32, on the one hand, the mucosal balls 8 with the zinc film adhered thereto are scooped up and transferred to the goal groove 101 to be flushed with clean ball liquid to restore a certain degree of cleanliness. On the other hand, the mucosal balls 8 with restored cleanliness re-enter the zinc liquid under the guidance of the volleyball plate 32 to continue to adhere to the zinc film. Through the recycling of the mucosal balls 8, the continuous transfer process of the zinc film can be realized, effectively reducing the content of the zinc film on the surface of the zinc liquid, thereby improving the galvanizing quality of the workpiece.

[0050] Supplementary explanation: Since the mucous membrane ball 8 floats freely on the surface of the zinc liquid, when the workpiece is immersed in the zinc liquid, the mucous membrane ball 8 is not easy to cause obstruction to the workpiece. Even if part of the mucous membrane ball 8 is pressed down into the zinc liquid by the workpiece, this part of the mucous membrane ball 8 will quickly float up under the buoyancy of the zinc liquid. Therefore, the mucous membrane ball 8 in the present application is not easy to affect the normal galvanizing process of the workpiece.

[0051] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and its improved conception, which should be covered by the protection scope of the present application.
