Description

Technical Field

[0001] This utility model relates to the field of steel pipe pickling, and in particular to a suspended pickling tank. Background Technology

[0002] Pickling steel pipes is primarily used to remove impurities such as oxide scale, rust, and oil from their surfaces, providing good surface conditions for subsequent processing and improving the overall performance of the steel pipes. Traditional pickling tanks come in two types: one made of stainless steel, which has high strength but cannot withstand strong acids; and the other made of polytetrafluoroethylene (PTFE), which can withstand strong acids but has lower strength. When steel pipes are placed in a PTFE pickling tank, the tank's service life is relatively short. Therefore, providing a suspended pickling tank that can withstand strong acids and has a long service life has become an urgent problem to be solved. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the aforementioned problems in the prior art, this utility model provides a suspended pickling tank.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A suspended pickling tank includes a pickling tank body, a material frame, a support bracket, a sealed chamber, and a bridge crane.

[0008] The bottom of the sealed chamber is recessed with the pickling tank body;

[0009] Two sets of support brackets are provided, which are arranged opposite to each other on both sides of the pickling tank and on the ground at the bottom of the sealed chamber.

[0010] The material frame is provided with several water-permeable holes, and the two ends of the material frame are provided with outwardly bent hooks, and the material frame is hung on the support bracket through the hooks;

[0011] The bridge crane is installed in the enclosed room and is used to lift the material frame.

[0012] Preferably, the hook has a Γ-shaped structure.

[0013] Preferably, the pickling tank is made of polytetrafluoroethylene.

[0014] Preferably, multiple exhaust fans are installed on the outer wall of the sealed room.

[0015] Preferably, the exhaust fan is connected to the waste gas treatment mechanism.

[0016] Preferably, the hook of the bridge crane is inverted T-shaped, and the material frame is provided with a T-shaped lifting groove corresponding to the hook.

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this utility model are as follows: By adopting the above technical solution, the steel pipe to be pickled is placed in the material frame. Under the action of the bridge crane, the material frame is hung on the support bracket by hooks, so that the material frame is suspended in the pickling tank. The strong acid in the pickling tank pickles the steel pipe in the material frame. At the same time, the pickling tank does not need to bear any weight. This makes the pickling tank made of polytetrafluoroethylene resistant to strong acid and has a long service life. The acid mist generated during the pickling process accumulates in the sealed room to prevent the acid mist from leaking out. Attached Figure Description

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figure 1 This utility model provides a suspended pickling tank, including a pickling tank body 1, a material frame 2, a support bracket 7, a sealed chamber 6, and a bridge crane 3.

[0030] The bottom of the sealed chamber 6 is recessed with the pickling tank body 1;

[0031] Two sets of support brackets 7 are provided, which are arranged opposite to each other on both sides of the pickling tank 1 and on the ground at the bottom of the sealed chamber 6.

[0032] The material frame 2 is provided with several water-permeable holes, and the two ends of the material frame 2 are provided with outwardly bent hooks 5, and the material frame 2 is hung on the support bracket 7 through the hooks 5;

[0033] The bridge crane 3 is installed inside the sealed chamber 6, and the bridge crane 3 is used to lift the material frame 2;

[0034] During use, the steel pipe to be pickled is placed in the material frame 2. Under the action of the bridge crane 3, the material frame 2 is hung on the support bracket 7 by the hook 5, so that the material frame 2 is suspended in the pickling tank 1. The strong acid in the pickling tank 1 pickles the steel pipe in the material frame 2. At the same time, the pickling tank 1 does not need to bear any weight. This makes the pickling tank 1, which is made of polytetrafluoroethylene, both resistant to strong acid and with a long service life. The acid mist generated during the pickling process accumulates in the sealed chamber 6 to prevent the acid mist from leaking out.

[0035] In this embodiment, the hook 5 has a Γ-shaped structure.

[0036] In this embodiment, the pickling tank 1 is made of polytetrafluoroethylene.

[0037] In this embodiment, multiple exhaust fans 4 are installed on the outer wall of the sealed chamber 6. The exhaust fans 4 are connected to the waste gas treatment mechanism. The exhaust fans 4 transport the acid mist accumulated in the sealed chamber 6 to the waste gas treatment mechanism to achieve waste gas treatment.

[0038] In this embodiment, the hook of the bridge crane 3 is inverted T-shaped, and the material frame 2 is provided with a T-shaped lifting groove corresponding to the hook.

[0039] The working principle of this utility model is as follows:

[0040] The steel pipe to be pickled is placed into the material frame 2. Under the action of the bridge crane 3, the material frame 2 is hung on the support bracket 7 by the hook 5, so that the material frame 2 is suspended in the pickling tank 1. The strong acid in the pickling tank 1 pickles the steel pipe in the material frame 2. At the same time, the pickling tank 1 does not need to bear any weight. This makes the pickling tank 1, which is made of polytetrafluoroethylene, both resistant to strong acid and with a long service life. The acid mist generated during the pickling process accumulates in the sealed chamber 6 to prevent the acid mist from leaking out.
