Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of process tank for metal material cleaning or pickling, especially the process tank for acid pickling after pipe material is placed. BACKGROUND

[0002] Pickling is an important step in the production and processing of metal pipes, mainly used to remove impurities such as oxides and oil stains on the surface of metal pipes to improve the surface quality and subsequent processing performance of the pipes. The traditional pickling process carrier is an open process tank with an upper opening. The process tank is configured with pickling solution. When pickling, multiple metal pipes that need to be pickled are placed in the process tank by means of lashing or hanging basket hoisting tools, soaked in the pickling solution, and then hoisted out after pickling. In actual production, in order to prolong the service life of the hoisting tool as much as possible, the hoisting tool is usually removed from the pickling solution after the metal pipes are immersed in the process tank. However, after the hoisting tool is removed, the multiple metal pipes are scattered on the bottom of the process tank, which is not conducive to the removal after pickling, especially the metal pipes on the bottom layer are easily pressed close to the inner corner by the weight of the metal pipes on the upper layer, which is not convenient for the cooperation of the hoisting tool and the removal of the metal pipes from the process tank. SUMMARY

[0003] In view of at least one of the above technical problems, the utility model provides a pipe pickling process tank, which adds a supporting device to the inner wall to provide space for the removal and repositioning of the hoisting tool. The specific technical solution is as follows:

[0005] In some embodiments of the present disclosure, the tank cylinder is an elongated cylinder body, and each supporting bracket is arranged along the long axis thereof.

[0006] In some embodiments of the present disclosure, the upper end of the tank cylinder is provided with a flat cylinder rim, and the upper end of the protective support does not protrude from the cylinder rim.

[0010] In some embodiments of the present disclosure, the middle part of the curved surface I is provided with an arc-shaped protrusion, and the two ends are provided with arc-shaped recesses.

[0011] In some embodiments of the present disclosure, the supporting bracket comprises a base fixedly connected to the inner bottom surface of the inner cavity of the tank, and the upper surface of the base is connected to the bottom support, wherein the bottom support is a vertical plate, and the curved surface I is arranged on the upper surface of the vertical plate.

[0012] In some embodiments of the present disclosure, the supporting bracket comprises a base fixedly connected to the inner bottom surface of the inner cavity of the tank, and the upper surface of the base is connected to the bottom support, wherein the bottom support is a vertical plate, and the curved surface I is arranged on the upper surface of the vertical plate.

[0014] Compared with the prior art, the pipe pickling process tank has the following beneficial effects:

[0015] By arranging at least one supporting bracket in front of and behind the bottom of the inner cavity of the tank, when the metal pipes are arranged in the tank, the multiple metal pipes can avoid contacting the inner wall of the tank, so that a hoisting operation space is reserved between the metal pipes and the inner wall of the tank, the hoisting tool can be easily taken out and arranged, and the process time is effectively shortened.

[0016] By arranging the supporting bracket, a distance can be reserved between the metal pipes and the inner bottom surface of the tank, so that the pollution of the deposited impurities on the bottom of the tank to the metal pipes can be effectively reduced.

[0017] By arranging the curved surface I and the curved surface II, the metal pipes can avoid contacting the supporting bracket, the pressure on the outer surface of the metal pipes can be reduced, and the appearance of the metal pipes can be prevented from being damaged due to the self-weight of the multiple metal pipes.

[0018] The structure is intuitive, the manufacturing cost is low, the compatibility with the existing pickling production line is high, and the market promotion is facilitated. BRIEF DESCRIPTION OF DRAWINGS
