Description

Technical Field

[0001] This utility model relates to the field of pickling tank technology, specifically to a pickling tank with detachable coils. Background Technology

[0002] In the pickling process, there are some pickling scenarios that require high temperatures, where the acid solution is often kept at a high temperature.

[0003] In traditional techniques, a heating system is typically installed inside the pickling tank. The core structure of this pickling tank is a coil system located at the bottom of the tank.

[0004] In existing technologies, coils are usually directly welded to the bottom of the pickling tank during the production process. However, this welding method has significant drawbacks: First, the height of the coil relative to the bottom of the tank and its own pipe spacing are permanently fixed after welding and cannot be adjusted. This means that when processing pipes of different specifications, the fixed coil spacing cannot achieve the optimal heating effect, which directly affects the pickling effect on the pipes. Second, when the coil fails, this rigid connection method makes the repair and replacement of the coil extremely difficult, often requiring the purchase of a new pickling tank.

[0005] In summary, the use of welded coils in pickling tanks results in the inability to adjust the height of the coils within the tank. This necessitates the purchase of new pickling tanks to meet different processing requirements or when the coils are damaged, leading to poor flexibility and maintainability, and ultimately wasting funds and equipment. Utility Model Content

[0006] This application provides a pickling tank with detachable coils to solve the technical problem that the existing pickling tanks use welding, which makes it impossible to adjust the coils and inconvenient to repair and replace them.

[0007] This application provides a pickling tank with a detachable coil, comprising: a coil body, a pickling tank body, and a plurality of first supports spaced apart along the length of the pickling tank body; the coil body and all the first supports are slidably connected in the vertical direction; each first support is provided with a fixing component for fixing the coil body, and each first support is detachably connected to the pickling tank body.

[0008] By adopting the above technical solution, multiple first supports are set up at intervals along the length direction, so that the coil body and all the first supports can be slidably connected in the vertical direction. This enables flexible adjustment of the overall height of the coil, and the coil body is fixed at the installation height by fixing components. This allows for optimization of heating distance and heat field distribution according to different processing requirements. At the same time, the detachable connection between the coil and the supports simplifies the maintenance and replacement process, significantly improving the adaptability and maintainability of the equipment.

[0009] Preferably, the fixing assembly includes multiple fixing members detachably connected to the first bracket, the coil body includes multiple heating tubes extending along the length direction of the pickling tank body, the lower end of each first bracket is provided with multiple first grooves extending along the length direction of the pickling tank body, each first groove is suitable for a heating tube to be embedded and slide in the vertical direction, and each first groove is provided with a fixing member abutting against the lower end of the heating tube.

[0013] Preferably, each first support has an upwardly protruding plate at its upper end, each plate extending along the width of the pickling tank body, and each plate gradually protruding upward from both ends to the middle.

[0014] By adopting the above technical solution, a convex plate that gradually protrudes from both ends to the middle is set on the upper end of each first support. This structure can effectively guide the workpiece to roll down to both sides of the pickling tank, avoid accumulation in the pickling tank, realize automatic flat feeding of the pipeline, and reduce the risk of collision caused by workpiece accumulation.

[0015] Preferably, a plurality of second supports are provided at the bottom of the pickling tank body, and the plurality of second supports are distributed at intervals along the length direction of the pickling tank body, and each first support is detachably connected to the upper end face of a second support.

This further increases the height of the coil in the pickling tank, avoids uneven heating caused by the small distance between the coil and the pickling tank, and enhances the connection rigidity of the overall frame.

[0017] Preferably, each second bracket has a second groove on its upper end face suitable for embedding the first bracket. The groove wall of the second groove has multiple through holes extending along the length of the pickling tank and multiple bolts installed in the through holes.

This design realizes the rapid and accurate positioning and firm fixation of the first bracket on the second bracket, ensuring the stability of the support structure. At the same time, the bolt connection method facilitates disassembly and adjustment.

[0019] Preferably, multiple pairs of vertically arranged and open-top sliding grooves are symmetrically provided on the two tank walls of the pickling tank body, and each end of the second bracket is embedded in a pair of sliding grooves and slides in the vertical direction.

[0020] By adopting the above technical solution, vertical sliding grooves with open tops are set on the two tank walls of the pickling tank body to cooperate with the second support, so that the second support and its upper structure can be pre-assembled and then hoisted in for installation or lifted out for disassembly, realizing the detachable installation of the second support and improving the convenience of equipment installation and disassembly.

[0021] Preferably, each second bracket has multiple drain holes spaced apart at its lower end.

[0022] By adopting the above technical solution, multiple drainage holes are provided at the lower end of each second bracket to facilitate rinsing and discharging of sludge during cleaning.

[0023] One or more technical solutions provided in this application have at least the following technical effects or advantages: 1. By sliding the coil and the support in the vertical direction, the overall height of the coil can be adjusted, thereby optimizing the heat field distribution for the processing requirements of workpieces of different specifications.
