Technical Field
[0001] This utility model relates to the field of steel production technology, specifically to a high-efficiency pickling tank for steel pipes. Background Technology
[0002] Steel is a material with specific shape, size, and properties, made from steel ingots, billets, or other steel products through pressure processing. Most steel processing involves pressure processing, which causes plastic deformation of the steel (billets, ingots, etc.). Based on the processing temperature, it can be divided into cold working and hot working.
[0003] In the steel production process, steel needs to be pickled. Currently, steel is mostly placed in pickling tanks for pickling. The water in the pickling tanks is mostly stagnant, which slows down the pickling process and results in low pickling efficiency.
[0004] Therefore, it is necessary to invent a high-efficiency pickling tank for steel pipes to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency pickling tank for steel pipes, comprising a pickling tank body, with water collection tanks fixedly connected to both the left and right sides of the pickling tank body, a water collection trough fixedly connected to the bottom of the pickling tank body, two sets of circulating pumps fixedly installed at the bottom of the pickling tank body, first connecting pipes fixedly connected to both the left and right sides of the water collection trough, the end of the first connecting pipe away from the water collection trough being fixedly connected to the inlet of the circulating pump, a second connecting pipe fixedly connected to the outlet of the circulating pump, the end of the second connecting pipe away from the circulating pump being fixedly connected to the water collection tank, and water inlet troughs opened on the inner walls of both the left and right sides of the pickling tank body.
[0007] By adopting the above technical solution, the steel pipe is placed inside the pickling tank for pickling. During the pickling process, the circulating pump draws the water from inside the pickling tank to the inside of the collection tank, and then flows into the inside of the pickling tank through the inlet tank, so that the water inside the pickling tank is in a flowing state, which can quickly pickle the steel pipe and improve the pickling efficiency of the steel pipe.
[0008] Optionally, a filter plate is fixedly connected to the upper end of the water collection tank.
[0009] By adopting the above technical solution, the filter plate filters impurities inside the pickling tank.

[0011] By adopting the above technical solution, the water inlet tank is used to allow the pickling solution inside the water collection tank to flow into the pickling tank.
[0012] Optionally, a sealing cover is fixedly connected to the upper end of the water collection tank.
[0013] By adopting the above technical solution, the sealing cover is used to seal the water collection tank.
[0014] Optionally, support rods are fixedly connected to the front and rear ends of the pickling tank body, and the upper surface of the support rods is provided with a slot.
[0015] Optionally, limit rods are fixedly connected to the upper ends of the left and right sidewalls of the pickling tank body, and multiple sets of support legs are fixedly connected to the bottom of the pickling tank body.

[0018] By adopting the above technical solution, the sliding cover plate slides back and forth above the pickling tank through the cooperation of the sliding groove and the limiting rod, thereby closing the top of the pickling tank.
[0019] Optionally, the sliding cover plate has insertion slots near both the front and rear ends, and a sealing baffle is inserted and fixedly connected inside the insertion slot.
[0020] By adopting the above technical solution, the sealing baffle is inserted into the insertion groove, so that the lower end of the sealing baffle is stuck in the groove, thereby sealing the front and rear ends of the pickling tank.
[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0022] This invention features a pickling tank with water collection tanks fixedly connected to both sides of the main body, a water collection trough fixedly connected to the bottom of the main body, a filter plate fixedly connected to the upper end of the water collection trough, and two sets of circulation pumps fixedly installed at the bottom of the main body. The circulation pumps draw the pickling solution from inside the pickling tank into the water collection tank, and then it flows into the pickling tank through the inlet trough, keeping the pickling solution in a flowing state to rinse the steel pipe, thereby improving the pickling efficiency of the steel pipe and achieving high-efficiency pickling. This solves the problem that existing pickling methods often place steel in pickling tanks where the water is mostly stagnant, resulting in a slow pickling speed and thus low pickling efficiency.

Two sets of circulating pumps 18 are fixedly installed at the bottom of the pickling tank body 1. First connecting pipes 19 are fixedly connected to both the left and right sides of the water collection trough 16. The end of the first connecting pipe 19 away from the water collection trough 16 is fixedly connected to the inlet of the circulating pump 18. A second connecting pipe 110 is fixedly connected to the outlet of the circulating pump 18.

A sealing cover plate 21 is fixedly connected to the upper end of the water collection tank 2.
[0032] During use, steel pipes are stacked inside the pickling tank body 1. Then, two sets of circulation pumps 18 are started. The circulation pumps 18 draw the pickling liquid from the collection tank 16 to the collection tank 2. When the pickling liquid in the collection tank 2 reaches the height of the inlet tank 14, the pickling liquid flows into the pickling tank body 1 through the inlet tank 14, making the pickling liquid inside the pickling tank body 1 flow, rinsing the surface of the steel pipe, increasing the pickling speed of the steel pipe, and thus improving the pickling efficiency of the steel pipe, achieving high-efficiency pickling.

[0034] Meanwhile, during the pickling of the steel pipe, the sliding cover plate 3 is slid forward to block the top of the pickling tank body 1. Then, the sealing baffle 32 is inserted into the insertion groove 31, so that the lower end of the sealing baffle 32 is engaged in the groove 13, sealing the front and rear ends of the pickling tank body 1 and improving the sealing performance of the pickling tank body 1.
[0035] The working principle of this utility model is as follows: In order to improve pickling efficiency, the pickling liquid inside the pickling tank body 1 is drawn into the water collection tank 2 by two sets of circulating pumps 18, and then flows into the pickling tank body 1 through the water inlet trough 14, so that the pickling liquid inside the pickling tank body 1 is in a circulating state, thereby improving pickling efficiency and achieving high-efficiency pickling.
