Description

Technical Field

[0001] The utility model relates to the field of metal surface treatment, in particular to a pickling tank heating device. Background Art

[0002] In shipbuilding, it is often involved in the surface treatment of pipes and fittings on board, mainly anti-rust galvanizing and other operations. Its purpose is to adapt to the working environment on the ocean, make it rust-proof, extend its service life, and avoid rust or leakage during the period.

[0003] Different metal pipes are often used in shipboard fluid transportation, refrigerant systems, gas pipelines, etc. After production and processing, these metal pipes are surface treated as needed and transported to special surface treatment sites for surface galvanizing and other operations. When stored in warehouses or placed outdoors, metal pipes often produce a lot of rust, so the rust on the surface of the metal pipes needs to be cleaned and galvanized. The surface-treated pipe products are transported to ships for installation and use.

[0004] Most existing methods of removing rust from metal pipes are to immerse them in a pickling tank for acidic rust removal. During the rust removal process, the metal pipes need to be placed in the pickling tank, and the pickling liquid in the pickling tank is used to remove the rust on the surface of the metal pipes. In order to improve the rust removal efficiency and shorten the rust removal time, a heating component will be installed in the pickling tank to improve the cleaning effect of the metal pipes. However, the existing heating component simply places the heating pipe into the pickling tank, and then uses a lifting rope to place the metal pipes into the pickling tank for pickling. However, when the metal pipes are placed in and lifted out of the pickling tank, the metal pipes are prone to touch and damage the heating pipes, thereby shortening the service life of the heating pipes.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a pickling tank heating device, comprising a tank body 1 with an opening at the top, a heating assembly 2 is clamped and installed on the inner bottom of the tank body 1, the heating assembly 2 is a semicircular ring structure with an opening at the top, and a plurality of equidistantly arranged heating pipes 3 are arranged on the outer wall of the heating assembly 2, and inclined guide plates 5 are movably installed on both sides of the heating assembly 2. As a preferred embodiment, the tank body 1 is a concrete structure, which can slow down the corrosion of the tank body 1 by the pickling liquid.

[0024] In this embodiment, a plurality of locking members 4 are provided at the inner bottom of the pool body 1, and a locking groove is provided inside the locking member 4. The cross-section of the locking groove is a convex structure, and the top of the locking groove passes through the locking member 4. An opening is provided at one end of the locking groove. A locking portion 201 is provided at the bottom of the heating component 2, and the locking portion 201 corresponds to the locking groove on the locking member 4.

[0025] During specific use, the locking portion 201 at the bottom of the heating component 2 slides into the locking groove in the locking piece 4, and the locking portion 201 is limited and fixed by the locking groove, so that the heating component 2 is fixedly installed on the inner bottom of the pool body 1, and the metal pipe 6 is limited by the groove of the heating component 2 to prevent the metal pipe 6 from colliding and damaging the heating tube 3.

[0026] In this embodiment, horizontal strip-shaped limit grooves 101 are provided on both sides of the interior of the pool body 1. The cross-section of the limit groove 101 is a T-shaped structure, and a limit opening 102 is provided on the limit groove 101. The guide plate 5 is inclined from top to bottom and from outside to inside. The top of the guide plate 5 extends horizontally outward, and a limit block 501 that slides with the limit groove 101 is provided at the end. The inner end of the guide plate 5 is located at the edge of the heating component 2.

[0027] During specific use, the limit block 501 at the top of the guide plate 5 is placed into the limit opening 102. Since the limit opening 102 is connected to the limit groove 101, the limit block 501 can be slid into the limit groove 101 through the limit opening 102, and the limit block 501 is limited and fixed by the limit groove 101, and then the guide plate 5 is installed on both sides of the interior of the pool body 1.
