Detailed Implementation

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a circulating water tank for pickling copper strips, including a tank body 1, a water inlet pipe 2 provided on the side of the tank body 1, a filter screen 3 provided at the upper end of the inside of the tank body 1, and a docking structure 4 provided on the side of the filter screen 3.

[0024] Pickling water is poured into tank 1. At this time, the pickling water will pass through filter screen 3. Impurities in the pickling water cannot pass through filter screen 3 and remain on filter screen 3. The pickling water will pass through filter screen 3 and enter tank 1. The pickling water can be drawn out through water inlet pipe 2 to achieve filtration and recycling of pickling water.

[0025] Please see Figure 1 , Figure 3 and Figure 4 This utility model provides a circulating water tank for pickling copper strips. The docking structure 4 includes a docking interface 41. The front and rear ends of the left and right sides of the tank body 1 are provided with docking interfaces 41. The tank body 1 is provided with a limiting port 42, which is located in the docking interface 41. The docking blocks 43 are opposite to the docking interfaces 41. The number of docking blocks 43 is the same as that of the docking interfaces 41. The docking blocks 43 are fixed to the left and right sides of the filter screen 3. The surface of the docking blocks 43 is fixed with a fixing plate 402 by bolts. A crossbar 403 is installed on the fixing plate 402. The crossbar 403 can be easily lifted by the staff. The top of the filter screen 3 is integrally formed with a guide plate 401. The guide plate 401 can prevent pickling water from flowing out through the docking interface 41. When the docking blocks 43 are installed into the docking interfaces 41, the guide plate 401 will press against the surface of the tank body 1 to facilitate the positioning and installation of the filter screen 3.

[0026] A fixed sleeve 44 is installed at the upper end of the inner part of the docking block 43. A pressure rod 45 passes through the fixed sleeve 44 and slides along the inner wall of the fixed sleeve 44. The pressure rod 45 also passes through the middle of the guide plate 401. A toothed plate 46 is fixed to the lower end of the pressure rod 45 by bolts. A limit groove 461 is opened on the side of the toothed plate 46.

[0027] The docking block 43 has an integrally formed positioning rod 47, and a connecting tooth 48 is installed on the positioning rod 47. The connecting tooth 48 and the positioning rod 47 are rotatably connected by a torsion spring. The connecting tooth 48 is engaged with the tooth plate 46. When the connecting tooth 48 is engaged with the tooth plate 46, the connecting tooth 48 is located in the limiting groove 461, which allows the connecting tooth 48 to swing when the tooth plate 46 slides, thereby improving stability. A limiting plate 49 is integrally formed on the connecting tooth 48. A fixing block 491 is installed inside the docking block 43. The limiting plate 49 is in contact with the surface of the fixing block 491, and the limiting plate 49 can slide along the surface of the fixing block 491, thereby improving the stability of the limiting plate 49 and preventing the limiting plate 49 from shaking. A spring 411 is installed inside the docking block 43, and the spring 411 is connected to the tooth plate 46.

[0028] A positioning sleeve 412 is provided at the lower end of the docking block 43, and a spring 411 is located in the positioning sleeve 412 to prevent the spring 411 from bending during movement. A slide cylinder 413 is integrally formed at the lower end of the toothed plate 46. The slide cylinder 413 slides along the surface of the positioning sleeve 412 to ensure that the toothed plate 46 does not wobble when sliding vertically up and down. When the toothed plate 46 is in contact with the top of the positioning sleeve 412, the limiting plate 49 will completely retract into the docking block 43, resulting in more accurate movement.

[0029] When the filter screen 3 needs to be disassembled for cleaning, press down on the pressure rod 45, which will push the toothed plate 46 downward. Since the connecting tooth 48 is engaged with the toothed plate 46, when the toothed plate 46 slides downward, the connecting tooth 48 will rotate along the surface of the positioning rod 47, and at the same time drive the limiting plate 49, so that the limiting plate 49 slides out of the limiting port 42 and enters the docking block 43, thereby releasing the limitation on the docking block 43. Then the docking block 43 can be moved upward, so that the docking block 43 slides out of the docking interface 41, completing the disassembly of the filter screen 3, so as to achieve the beneficial effect of convenient disassembly. During installation, insert the docking block 43 into the docking interface 41. Under the action of the spring 411, the limiting plate 49 will be locked into the limiting port 42, thus limiting the docking block 43, so as to achieve the beneficial effect of convenient installation.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
