DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the following further describes the utility model in conjunction with specific embodiments.

[0026] As Figure 1 - Figure 5 Shown in the drawing, a square tube galvanization automatic pickling device, including bottom plate 1, the middle part of bottom plate 1 upper surface is fixedly connected with support seat 2, the upper surface of support seat 2 is fixedly connected with reaction tank 3, and the upper surface of reaction tank 3 is abutted with support plate 4, and the lower surface of support plate 4 is fixedly connected with object carrier frame 5, and the upper surface of bottom plate 1 is movably connected with lifting mechanism 6;

[0027] The lifting mechanism 6 comprises a first motor 61 fixedly connected to the front side of the upper surface of the bottom plate 1, four threaded pipes 66 fixedly connected to the outer side of the lower surface of the supporting plate 4 in a ring shape, threaded rods 65 threadedly connected in the inner cavities of the threaded pipes 66, sprockets 63 fixedly connected to the lower surfaces of the threaded rods 65, a chain 64 commonly meshingly connected to the middle portions of the outer peripheries of the four sprockets 63, the middle portions of the front threaded rods 65 fixedly connected to the output end of the first motor 61, and supporting rods 62 rotatably connected to the middle portions of the remaining three threaded rods 65 and fixedly connected to the upper portion of the bottom plate 1.

[0028] It should be noted that the bottom plate 1 and the supporting plate 4 are used to support the reaction tank 3, the reaction tank 3 is used to perform a series of treatments such as pickling on the square tube, the supporting plate 4 is used to support the object frame 5, and the object frame 5 is used to place the square tube. The lifting mechanism 6 realizes the lifting control of the supporting plate 4 and the object frame 5 through the driving of the first motor 61. After the first motor 61 is started, the output end drives the front threaded rod 65 to rotate. Since the four threaded rods 65 are commonly meshingly connected through the middle portion of the chain 64, the four threaded rods 65 will rotate synchronously. The threaded rods 65 are threadedly matched with the threaded pipes 66, so that the supporting plate 4 and the object frame 5 realize lifting under the rotation of the threaded rods 65, thereby conveniently adjusting the position of the object frame 5 and the square tube inside the object frame 5 in the reaction tank 3 and facilitating the pickling operation.

[0029] As shown in Figure 1 Figure 4 The middle portion of the reaction tank 3 is movably connected with a stirring mechanism 8, the upper portion of the inner cavity of the reaction tank 3 is fixedly connected with a cleaning mechanism 7, the lower portion of the right outer periphery of the reaction tank 3 is fixedly connected with a liquid outlet 10, and the upper portion of the left outer periphery of the reaction tank 3 is fixedly connected with a liquid inlet 9.

[0030] It should be noted that the cleaning mechanism 7 is used to clean the reaction tank 3 and the object frame 5, the stirring mechanism 8 is used to stir the liquid inside the reaction tank 3, the liquid outlet 10 is used to output the liquid in the reaction tank 3, and the liquid inlet 9 is used to add the required liquid for reaction into the reaction tank 3.

[0031] As shown in Figure 2 Figure 4 The cleaning mechanism 7 comprises a water pump 71 fixedly connected to the left side of the upper surface of the bottom plate 1, a cleaning pipe 73 fixedly connected to the upper portion of the inner cavity of the reaction tank 3, a conveying pipe 72 fixedly connected to the outer periphery of the cleaning pipe 73, a plurality of nozzles 74 fixedly connected to the inner side of the cleaning pipe 73, and the lower portion of the conveying pipe 72 is fixedly connected to the output end of the water pump 71.

[0032] ​​It should be noted that the cleaning mechanism 7 is powered by the water pump 71, and the cleaning liquid is pumped from the liquid inlet 9 into the delivery pipe 72, and then delivered to the cleaning pipe 73 through the delivery pipe 72. The multiple spray heads 74 on the inside of the cleaning pipe 73 uniformly spray the cleaning liquid in the reaction tank 3, and the opposite pipe is fully cleaned. The continuous operation of the water pump 71 ensures the continuous supply of cleaning liquid, so that the cleaning operation can continue.

[0033] As shown in Figure 4 and Figure 5 , the stirring mechanism 8 includes a motor 81, and the output end of the motor 81 is fixedly connected with a connecting plate 82. The upper surface of the connecting plate 82 is fixedly connected with four fixed rods 83 arranged in a ring shape. The outer periphery of the fixed rod 83 is rotatably connected with a roller brush 84. The upper surface of the connecting plate 82 is fixedly connected with a stirring fan blade 85.

[0034] It should be noted that the stirring mechanism 8 is driven by the motor 81 to stir the pickling liquid in the reaction tank 3. The output end of the motor 81 drives the connecting plate 82 and the fixed rod 83, the roller brush 84 and the stirring fan blade 85 on it to rotate. At the same time, the rotation of the stirring fan blade 85 makes the pickling liquid in the reaction tank 3 flow, which improves the contact area and contact time of the pickling liquid with the square tube, thereby further improving the pickling effect.

[0035] As shown in Figure 5 , the inner wall of the reaction tank 3 and the outer wall of the object carrier frame 5 are slidably connected with four roller brushes 84 arranged in a ring shape. The middle part of the roller brush 84 is rotatably connected to the upper part of the outer periphery of the fixed rod 83.

[0036] It should be noted that the roller brush 84 brushes the reaction tank 3, the object carrier frame 5 and the square tube inside them during rotation, enhancing the cleaning effect and avoiding the deposition of the reaction tank 3 and the object carrier frame 5. When the support plate 4 and the object carrier frame 5 are lifted, the roller brush 84 can reduce the friction between the object carrier frame 5 and the inner wall of the reaction tank 3, protect them from damage, and ensure the smooth lifting process.

[0037] As shown in Figure 3 , the bottom of the object carrier frame 5 is provided with a plurality of filter holes, and the outer periphery of the object carrier frame 5 is provided with a plurality of rectangular holes arranged in a ring shape.

[0038] It should be noted that the plurality of filter holes in the bottom of the object carrier frame 5 allows the pickling liquid to penetrate between the square tubes during cleaning, fully cleaning each part of the square tube. At the same time, the plurality of rectangular holes arranged in a ring shape on the outer periphery of the object carrier frame 5 are beneficial to the flow and discharge of the pickling liquid, ensuring the efficient cleaning operation.

[0039] As shown in Figure 5As shown, the lower surface of the second motor 81 is fixedly connected to the middle of the upper surface of the bottom plate 1.

[0040] It should be noted that the lower surface of the second motor 81 is fixedly connected to the middle of the upper surface of the bottom plate 1, and this fixing mode ensures the stability and reliability of the stirring mechanism 8.

[0041] The working principle of the utility model is: first, the square tube is placed in the object carrier frame 5, then the acid solution is injected into the reaction tank 3 through the liquid inlet 9, the first motor 61 is started to drive the chain wheel 63 to rotate, the chain 64 drives the four threaded rods 65 to rotate together, thereby driving the threaded pipe 66 and the supporting plate 4 to lift, adjusting the depth of the object carrier frame 5 in the reaction tank 3, the square tube in the object carrier frame 5 is completely immersed in the acid solution, the second motor 81 is started to drive the connecting plate 82 to rotate, the stirring fan blade 85 and the fixed rod 83 drive the acid solution to stir, the acid solution and the square tube are fully contacted, the drum brush 84 cleans the inner wall of the reaction tank 3 and the outer wall of the object carrier frame 5, avoiding the production of precipitate to reduce the service life of the equipment. After pickling, the acid solution is discharged through the liquid outlet 10, then the cleaning liquid is pumped through the conveying pipe 72 into the cleaning pipe 73 through the water pump 71, and then sprayed through the nozzle 74 to clean the reaction tank 3, the object carrier frame 5 and the square tube, and the second motor 81 is also started to stir the cleaning liquid during the cleaning process, accelerating the cleaning efficiency.
