Description

Technical Field

[0001] This utility model relates to the field of pickling equipment, and in particular to a pickling equipment for treating titanium anode substrates. Background Technology

[0002] Titanium-based anodes are widely used in industries involving solutions, such as chlor-alkali industry, hypochlorite, steel plate galvanizing, electrolytic water treatment, industrial water treatment, hydrometallurgy, aluminum and copper foil manufacturing, cathodic protection, seawater desalination, and electroplating. The preparation method of titanium anodes is thermal decomposition, and the preparation process is as follows: titanium substrate surface treatment - coating solution preparation - titanium-based coating solution - drying - sintering - annealing. The surface treatment of titanium substrate consists of degreasing, sandblasting, hot straightening, and pickling. Among these, the quality and efficiency of pickling directly affect the performance and production efficiency of titanium anode products. Pickling of titanium anode substrate involves immersing the substrate in an aqueous solution of sulfuric acid or the like to remove oxide films and other thin films from the metal surface.

[0003] The existing publication number CN210065931U discloses an acid pickling device for efficiently treating titanium anode substrates, including an acid pickling tank with a mesh groove inside. The bottom of the mesh groove has a first slot for fixing the titanium anode substrate, and several second slots are respectively provided on the left and right sides of the mesh groove. Titanium rods are vertically fixed between the left and right sides of the mesh groove through two opposing second slots. Before the actual acid pickling work begins, the number of titanium rods can be increased or the height of the titanium anode substrates from the bottom of the mesh groove can be adjusted according to the number of titanium anode substrates to be pickled and the size of the titanium anode substrate plates. This forms multiple layers of partitions inside the mesh groove, achieving the purpose of acid pickling titanium substrates of different sizes and shapes, and improving work efficiency. However, the acidic aqueous solution is relatively troublesome to replace when using the above-mentioned acid pickling device.

[0004] Therefore, it is necessary to provide a new pickling apparatus for treating titanium anode substrates to solve the above-mentioned technical problems. Utility Model Content

[0008] Furthermore, the clamp includes a first hook, a second hook, a connecting plate, multiple first clamps, and multiple second clamps.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in, Figure 1 A schematic diagram of the overall structure of the pickling device for treating titanium anode substrates provided by this utility model; Figure 2 for Figure 1 The enlarged structural diagram at point A is shown below; Figure 3 A schematic diagram of the pickling tank provided by this utility model; Figure 4 for Figure 3 The enlarged structural diagram at point B is shown.

[0021] In the specific implementation process, such as Figures 1-4 As shown, the pickling device for treating titanium anode substrates includes a frame 1 and multiple pickling tanks 2 mounted on the frame 1. A storage tank and a supply pipe for supplying acidic aqueous solution are fixedly installed on the back of the frame 1. Multiple extraction pumps 3 are also provided at the bottom of the frame 1. The two ends of the multiple extraction pumps 3 are respectively connected to the inner cavity of the pickling tank 2 and the inner cavity of the storage tank. The multiple pickling tanks 2 are also equipped with clamps 4 for fixing the titanium anode substrate. The acidic aqueous solution in the pickling tank 2 is pumped into the storage tank for replacement by the extraction pumps 3. During this process, the pickling tank 2 is always kept sealed, which saves manpower and improves safety.

[0022] It should be noted that the liquid supply pipe includes a main pipe 14 and multiple branch pipes 15. One end of each branch pipe 15 is connected to the inner cavity of the main pipe 14, and the other end of each branch pipe 15 is connected to the inner cavity of multiple pickling tanks 2. Valves are provided at the output ends of the pickling tanks 2 and the branch pipes 15.

[0023] The main pipeline 14 can supply acidic aqueous solution by an external supply pump. In addition, all parts through which the acidic aqueous solution passes are coated with corrosion-resistant material.

[0024] The top of the pickling tank 2 is hinged with a sealing cover 5. Both sides of the pickling tank 2 are also equipped with telescopic electric cylinders 12 that drive the sealing cover 5 to be fastened to the top of the pickling tank 2. The two ends of the telescopic electric cylinder 12 are respectively rotatably connected to the fixing plates 13. The two fixing plates 13 are respectively fixedly installed on the pickling tank 2 and one side of the sealing cover 5. The telescopic electric cylinder 12 controls the sealing cover 5 to be fastened or opened, ensuring the airtightness of the pickling tank 2 during the pickling process and preventing the odor from spreading.

[0025] In one specific implementation, the clamp 4 includes a first hook 6, a second hook 7, a connecting plate 8, multiple first clamps 9, and multiple second clamps 10. The first hook 6 is fixedly installed on the inner wall of the sealing cover 5. The second hook 7 passes through the first hook 6 and is detachably installed on the top of the connecting plate 8. The multiple first clamps 9 are fixedly installed side by side on the bottom of the connecting plate 8. The center of the multiple second clamps 10 is hinged to the center of the multiple first clamps 9, and each connection between the multiple second clamps 10 and the multiple first clamps 9 is provided with a torsion spring 11. By pressing the second clamp 10, the torsion spring 11 is contracted, and the titanium anode substrate is placed between the first clamp 9 and the second clamp 10. When the second clamp 10 is released, the titanium anode substrate is clamped and fixed under the rebound force of the torsion spring 11. When the sealing cover 5 is fastened to the top of the pickling tank 2, the titanium anode substrate is immersed in the acidic aqueous solution for pickling.

[0026] The working principle of this utility model is as follows: When the device is in use, pressing the clamping plate 2 10 causes the torsion spring 11 to contract, and the titanium anode substrate is placed between the clamping plate 1 9 and the clamping plate 2 10. When the clamping plate 2 10 is released, the titanium anode substrate is clamped and fixed under the rebound force of the torsion spring 11. The extension and retraction control of the telescopic electric cylinder 12 drives the sealing cover 5 to be fastened or opened. When the sealing cover 5 is fastened to the top of the pickling tank 2, the titanium anode substrate is immersed in the acidic aqueous solution for pickling. The acidic aqueous solution in the pickling tank 2 is pumped into the storage tank for replacement by the extraction pump 3. During this process, the pickling tank 2 is always kept sealed, which saves manpower and improves safety.
