Technical Field

[0001] This utility model relates to the technical field of galvanized pipe processing equipment, specifically to an acid immersion device for hot-dip galvanized square and rectangular pipes. Background Technology

[0002] Pickling is a method of removing oxide scale and rust from the surface of steel using acid solutions. It is a method of cleaning metal surfaces and is usually carried out in conjunction with pre-coating. Generally, the workpiece is immersed in an aqueous solution of sulfuric acid or the like to remove thin films of oxides from the metal surface. It is a pretreatment or intermediate treatment for processes such as electroplating, enamel, and rolling.

[0003] In the existing pickling process for square and rectangular tubes, the galvanized tubes are usually placed in the pickling tank manually, which is time-consuming, labor-intensive, and has low production efficiency. To address this, we propose an acid immersion device for hot-dip galvanized square and rectangular tubes.

[0004] Therefore, it is necessary to provide an acid leaching apparatus for hot-dip galvanized square and rectangular tubes. Utility Model Content

[0005] The purpose of this invention is to provide an acid pickling device for hot-dip galvanized square and rectangular tubes, so as to solve the problems of low pickling efficiency and time-consuming and labor-intensive pickling.

[0027] according to Figure 1-6This embodiment provides an acid leaching device for hot-dip galvanized square and rectangular tubes, including a storage tank 1. A material platform 2 and a conveyor platform 3 are fixedly installed on the storage tank 1, respectively, on both sides of the storage tank 1. A crossbeam 10 is fixedly installed in the storage tank 1. An electric push rod 21 is fixedly installed on the upper end face of the crossbeam 10, and an electric push rod 22 is fixedly installed on the lower end face of the crossbeam 10. A motor 11 is fixedly installed on the storage tank 1, and a connecting shaft 111 is fixedly installed at the output end of the motor 11. The connecting shaft 111 is rotatably connected to the storage tank 1. A connecting shaft 212 is rotatably installed on the lower side of the storage tank 1. Two upper sprockets 121 are fixedly connected to the connecting shaft 111, and two lower sprockets 122 are fixedly installed on the connecting shaft 212. The two upper sprockets 121 and lower sprockets 122 are connected by a chain 13 for stable clamping of the square and rectangular tubes. The sprocket 121 and lower sprocket 122 allow for synchronous rotation. Multiple fixing blocks 14 are fixedly mounted on both sets of chains 13 facing each other. A sleeve 152 is fixedly mounted on each fixing block 14. A sleeve rod 151 is slidably inserted into the sleeve 152. The sleeve 152 and sleeve rod 151 are fixedly connected by a spring 153. A fixing plate 19 is fixedly mounted on the sleeve 152. A clamping plate 15 is fixedly mounted on one end of the sleeve rod 151. A protrusion is provided on the clamping plate 15. The plate facilitates the electric push rod 22 to push the clamping plate 15. A baffle is set on the clamping plate 15. As the rectangular tube moves with the chain 13, the orientation of the upper and lower structures changes. When the rectangular tube is in the pickling solution and is in a vertical state, the rectangular tube is affected by buoyancy. The weight of the rectangular tube itself is less than the weight in the air. The restoring force of the spring 153 needs to be greater than the weight of the rectangular tube in the pickling solution to prevent the clamping plate 15 from being insecure in clamping the rectangular tube.

[0028] An electric push rod 31 is fixedly installed at one end of the material platform 2, and a push plate 311 is fixedly installed at the output end of the electric push rod 31; an electric push rod 45 is fixedly installed on the conveyor platform 3, and a slide block 33 is slidably installed on the conveyor platform 3. A conveying device 30 is provided on the slide block 33. The conveying device 30 is a belt conveyor, and the output end of the electric push rod 45 is fixedly connected to the slide block 33.

[0029] A second motor 16 is fixedly installed on the lower side of the outer wall of the storage tank 1. A turbine 17 is fixedly installed at the output end of the second motor 16. The turbine 17 is rotatably installed on the inner wall of the storage tank 1. The rotation of the turbine 17 drives the liquid in the pickling tank to flow relative to each other, so that the impact of the water flow removes the rust adhering to the surface of the square and rectangular tubes, thereby improving the pickling efficiency.

[0030] The output end of the second motor 16 is rotatably and sealed to the liquid storage tank 1 to prevent leakage.

[0031] Multiple protrusions 18 are fixedly installed on the inner side of the fixing block 14 and the clamping plate 15, which not only clamp the rectangular tube, but also reduce the contact area of ​​the rectangular tube.

[0032] The connecting plate 23 is configured to cooperate with the clamping plate 15.

[0033] The conveyor table 3 is provided with a slide groove 34, and the slide block 33 is slidably connected to the slide groove 34.

[0034] The specific operation is as follows: When in use, the rectangular tubes are neatly stacked on the material platform 2. Motor 11 is started to rotate the upper sprocket 121, simultaneously rotating the lower sprocket 122 via chain 13, allowing the fixed block 14 on chain 13 to move. Rotating the upper sprocket 121 starts motor 21, driving the turbine 17 to rotate, thus creating a relative water flow in the storage tank 1. The clamping plate 15 is rotated to a position engaging with the electric push rod 22. The electric push rod 22 is started, pushing the clamping plate 15, increasing the distance between the clamping plate 15 and the fixed plate 19. The electric push rod 31 is started, pushing the rectangular tubes onto the sleeve 152 and the sleeve rod 151. The electric push rod 22 is then reset, allowing the clamping plate 15 to engage with the fixed plate 19. The fixed plate 19 can clamp the rectangular tube. The motor 11 continues to rotate, driving the rectangular tube into the pickling solution. The turbine 17 rotates, causing the liquid in the pickling tank to flow relative to each other. This allows the impact of the water flow to remove the rust adhering to the surface of the rectangular tube. When the rectangular tube moves to one side of the conveyor table 2, the motor 11 stops. The electric push rod 35 starts, driving the conveying device 30 on the slide 33 to move below the rectangular tube. The electric push rod 21 starts, pushing the clamping plate 15, increasing the distance between the clamping plate 15 and the fixed plate 19, causing the rectangular tube to fall onto the conveying device 30. The electric push rod 35 and the electric push rod 21 reset, thus allowing the rectangular tube that has fallen onto the conveying device 30 to proceed to the next step of transportation processing.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
