[0004] In the existing technology, steel pipes are fed one by one for pickling to ensure that the pickling of steel pipes is sufficient. However, when using this method for pickling, the bundled steel pipes need to be disassembled and fed one by one. After pickling, the scattered steel pipes need to be reorganized and bundled, which greatly increases the workload. Utility Model Content

[0005] This utility model provides a pickling equipment for seamless steel pipes with simple and convenient feeding and discharging, in order to solve the problems in the background art mentioned above.

[0006] In view of this, the present invention aims to provide a pickling device for seamless steel pipes. The device includes a pickling tank and a storage assembly disposed within the pickling tank. The storage assembly includes a fixed frame and multiple storage compartments disposed on the fixed frame. The top opening of each storage compartment allows bundled steel pipes to enter. A mesh is provided on the side of each storage compartment to allow liquid from the pickling tank to pass through and enter the storage compartment. Clamping members are provided on both sides of the opening of each storage compartment, allowing the bundled steel pipes to be clamped and fixed by the clamping members after the binding straps are untied.

[0007] By setting up the storage components, bundles of steel pipes can be placed into the storage bin for pickling. After feeding, the binding straps on the steel pipes are untied, allowing the steel pipes to spread out in the storage bin, so that the steel pipes can be fully pickled. During pickling, the two ends of the binding straps are fixed, and after pickling, the two ends of the binding straps are simply tightened again to bind the steel pipes in the storage bin. This allows for the loading and unloading of bundled steel pipes and the thorough pickling of bundled steel pipes.

[0008] Furthermore, the top of the storage compartment is provided with limit plates on both sides of the opening, and the clamping member is disposed on the limit plates.

[0009] The limit plate is designed to prevent steel pipes inside the storage compartment from rolling out of the storage compartment.

[0010] Furthermore, the pickling tank is also equipped with a swing mechanism that can drive the storage bin to swing repeatedly.

[0011] Furthermore, the swing mechanism includes a swing motor, an incomplete gear, and a transmission gear. The swing motor is mounted on the pickling tank, and the incomplete gear is connected to the swing motor and rotates under the drive of the swing motor.

[0012] The storage compartment is mounted on a fixed frame via a rotating shaft, and the transmission gear is fixed on the rotating shaft. The transmission gear meshes with the incomplete gear for transmission. A counterweight is provided at the bottom of the storage compartment, so that the opening of the storage compartment always faces upwards when there is no external force, and that the storage compartment can rotate and reset by its own weight after rotation.

[0013] The oscillating motor drives the incomplete gear to rotate, which in turn drives the storage bin to rotate, causing the steel pipes inside the storage bin to roll against each other, thus improving the pickling effect.

[0014] Furthermore, the multiple storage compartments are coaxially arranged, and the multiple storage compartments can rotate synchronously with the rotation of the shaft.

[0015] The synchronous rotation of multiple storage bins can improve the acid efficiency of the steel pipes in the multiple storage bins.

[0016] Furthermore, a drain pipe is provided at the bottom of the pickling tank.

[0017] Install a drain pipe and control its opening and closing to regulate the discharge of pickling solution, facilitating the replacement of the pickling solution.

[0018] Furthermore, a lifting mechanism is provided inside the pickling tank, which is used to drive the lifting of the fixed frame.

[0019] The lifting mechanism moves the storage bin in and out of the pickling tank, and can adjust the height of the storage bin in the pickling tank. When discharging, the steel pipe and storage bin are moved to the top of the pickling liquid for discharge.

[0020] Furthermore, the top of the pickling tank is equipped with a hoisting mechanism for loading and unloading bundles of steel pipes.

[0021] It facilitates the entry and exit of bundled steel pipes from the storage warehouse, enabling automatic loading and unloading and eliminating the need for manual handling.

[0022] The pickling equipment for seamless steel pipes disclosed in this utility model, through the setting of the storage component, can put bundled steel pipes into the storage chamber for pickling. After feeding, the binding straps on the steel pipes are untied, allowing the steel pipes to spread out in the storage chamber for pickling. After pickling, the two ends of the binding straps are directly tightened to bundle the steel pipes, and the bundled steel pipes are taken out from the storage chamber. Compared with the prior art, the method of feeding in bundles can achieve a thorough pickling of steel pipes, and the feeding and unloading are convenient and fast, eliminating the need for individual feeding and improving the pickling efficiency of steel pipes.

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices. "Fixed" or "fixed connection" generally refers to common mechanical connection methods, such as threaded connections, welding, or bonding.

[0034] In existing technologies, steel pipes are fed one by one for pickling to ensure sufficient pickling. However, this method requires disassembling the bundled steel pipes before feeding them one by one, and after pickling, the scattered steel pipes need to be reorganized and bundled, which greatly increases the workload. Therefore, there is a need for pickling equipment that can feed and discharge steel pipes in bundles and ensure sufficient pickling.

[0035] This utility model provides a pickling equipment for seamless steel pipes, such as... Figure 1 , Figure 2 and Figure 3As shown in this embodiment, a pickling device for seamless steel pipes is provided. The pickling device includes a pickling tank 1 and a storage assembly within the pickling tank 1. The pickling tank 1 contains pickling solution for pickling the steel pipes. The storage assembly stores the steel pipes for pickling. The storage assembly includes a fixed frame 2 and multiple storage compartments 3 mounted on the fixed frame 2. In this embodiment, three storage compartments 3 are provided for simultaneous pickling of three bundles of steel pipes to improve pickling efficiency. The top of each storage compartment 3 is open, allowing the bundled steel pipes to enter the compartment. Mesh 5 is provided on the sides and bottom of each storage compartment 3, allowing the pickling solution to pass through and fully contact the steel pipes. Clamping elements 4 are provided on both sides of the opening of each storage compartment 3; these clamping elements 4 can be spring clamps. After the bundled steel pipes enter the storage compartment 3, the binding straps are untied, and each end of the straps is clamped and fixed by a clamping element 4.

[0036] This invention, through the design of the storage component, enables bundled steel pipes to be placed into the storage chamber 3 for pickling. After feeding, the binding straps on the steel pipes are untied, allowing the pipes to spread out within the storage chamber 3 for pickling. After pickling, the binding straps are retied to bind the pipes together, and the bundled steel pipes are removed from the storage chamber 3. Compared with existing technologies, this bundled feeding method achieves thorough pickling of the steel pipes, with convenient and fast feeding and unloading, eliminating the need for individual pipe feeding and improving the pickling efficiency of the steel pipes.

[0037] To prevent the steel pipe from detaching from the storage chamber 3 during pickling, limit plates 6 are provided on both sides of the opening at the top of the storage chamber 3. The limit plates 6 are vertically arranged, and the clamping parts 4 are placed on the limit plates 6. The limit plates 6 restrict the steel pipe inside the storage chamber 3 from rolling out of the storage chamber 3.

[0038] To improve the pickling effect, a swing mechanism is installed in pickling tank 1, such as... Figure 4As shown, the oscillating mechanism includes an oscillating motor 7, an incomplete gear 8, and a transmission gear 9. The oscillating motor 7 is installed on the inner wall of the pickling tank 1 and is waterproofed. The incomplete gear 8 is connected to the output end of the oscillating motor 7 and rotates under the drive of the oscillating motor 7. The storage compartment 3 is mounted on the fixed frame 2 via a rotating shaft, allowing the storage compartment 3 to rotate on the fixed frame 2. The transmission gear 9 is fixed on the rotating shaft, allowing the transmission gear 9 and the storage compartment to rotate together. The transmission gear 9 meshes with the incomplete gear 8, thereby realizing the rotation of multiple storage compartments 3 controlled by the oscillating motor 7. To cooperate with the incomplete gear to allow the storage compartment 3 to reset, in A counterweight is installed at the bottom of the storage chamber 3, so that the opening of the storage chamber 3 always faces upwards when no external force is applied, and the storage chamber 3 can rotate and reset itself by its own weight after rotation. The swing motor 7 drives the incomplete gear 8 to rotate, and the rotation of the incomplete gear 8 drives the storage chamber 3 to rotate, so that the steel pipes in the storage chamber 3 roll against each other, improving the pickling effect. When the incomplete gear 8 rotates to the point that it does not mesh with the transmission gear 9, the storage chamber 3 resets under the action of gravity. Then, as the incomplete gear 8 continues to rotate, it drives the storage chamber 3 to rotate again. This process repeatedly drives the storage chamber to swing, which fully improves the mobility of the steel pipes in the storage chamber 3 and improves the pickling effect.

[0039] Multiple storage chambers 3 are set up coaxially and are fixedly connected to each other by rotating shafts. The connection of multiple storage chambers 3 enables the storage chambers 3 to rotate step by step, ensuring that the pickling effect of steel pipes in multiple storage chambers 3 is consistent and improving the acid efficiency of steel pipes in multiple storage chambers 3.

[0040] To facilitate the replacement of pickling solution, a drain pipe 10 is installed at the bottom of the pickling tank 1. A valve body is installed inside the drain pipe 10 to control the opening and closing of the drain pipe 10 and control the discharge of pickling solution.

[0041] To facilitate the loading and unloading of steel pipes, a lifting mechanism 11 is installed in the pickling tank 1. The lifting mechanism 11 is used to drive the lifting of the fixed frame 2. The lifting mechanism 11 drives the fixed frame 2 to move so that the storage bin 3 can enter and exit the pickling tank 1. Therefore, the height of the storage bin 3 in the pickling tank 1 can be adjusted by the lifting mechanism 11, and the steel pipe and the storage bin 3 can be moved to the upper end of the pickling liquid for unloading when discharging.

[0042] To enable automatic loading and unloading of bundled steel pipes, a hoisting mechanism is installed at the top of the pickling tank 1. The hoisting mechanism moves and transports the bundled steel pipes by pulling up the straps, facilitating the automatic loading and unloading of bundled steel pipes into and out of the storage bin 3 and avoiding manual handling.

[0043] The working principle of this utility model is as follows: a hoisting mechanism sends the bundled steel pipes to be pickled into the storage chamber 3, and then the binding straps on the steel pipes are loosened. At this time, the binding straps are loosened and no longer restrict the steel pipes. The binding straps and steel pipes are together in the storage chamber 3, and the steel pipes are scattered and dispersed in the storage chamber 3. The swing motor 7 is started to drive the incomplete gear 8 to rotate, so that the storage chamber 3 rotates at a certain angle, causing the steel pipes to roll in the storage chamber 3 and fully contact the pickling solution for pickling. The storage chamber 3 is driven to rotate repeatedly to ensure that the steel pipes are fully pickled. After pickling is completed, the binding straps are tightened again to gather the steel pipes in the storage chamber 3. The binding straps re-bind the steel pipes, and then the hoisting mechanism takes the steel pipes out of the storage chamber 3.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
