Description

Technical Field

[0001] This utility model relates to a high-performance pickling tank for stainless steel pipes. Background Technology

[0002] Impurities will still be generated when high-performance stainless steel pipes are pickled. After a certain number of steel pipes have been pickled, the pickling tank needs to be emptied and the inside of the pickling tank needs to be cleaned to remove these impurities. Patent CN217378041U discloses a waste acid tank for pickling steel pipes that is easy to clean. It includes a main module, a retrieval module, and a liquid supply module. The main module includes a main tank body and two support plates connected to the bottom of the main tank body. The retrieval module includes two mounting plates connected to the top of the main tank body and a winding mechanism set between the two mounting plates. By turning on the forward and reverse motors, the forward and reverse motors drive one of the rotating rods and the winding roller to rotate. At the same time, through the cooperation between the two transmission rollers and the transmission chain, the other rotating rod and the winding roller are driven, so that the two winding rollers wind up the four winding ropes, so that the four fixed blocks pull the filter screen upward. The four sliders slide in the four slide grooves respectively, thereby limiting the position of the filter screen, so that the filter screen rises vertically to retrieve impurities, thus making it convenient for workers to handle impurities. However, judging from the publicly available technical solutions, the overall structure of its salvage module is not reliable enough and cannot withstand the mass acid washing of steel pipes. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-performance pickling tank for stainless steel pipes, which is equipped with a more reliable support and has the ability to collect impurities in the pickling tank.

[0004] The technical solution of this utility model is: a high-performance stainless steel pipe pickling tank, including a support set in the pickling tank. The support includes a bottom frame, two side frames respectively set on both sides of the bottom frame, and a support plate set on the two side frames in a V-shape. A reinforcing beam is provided in the middle of the bottom frame. The bottom of the bent part of the support plate abuts against the top of the reinforcing beam. A set of long grooves is provided on both sides of the support plate. The grooves in the two sets of long grooves extend from one end of the support plate to the bent part of the support plate. The grooves in the two sets of long grooves are staggered. The bottom frames on both sides of the reinforcing beam are also equipped with filter screens, and the bottom of the bottom frame and the bottom of the pickling tank are kept at a distance.

[0005] Furthermore, each of the two trays is provided with a support plate at its bottom.

[0006] Furthermore, multiple support columns are connected between the two support plates and the bottom frame.

[0007] Furthermore, the outer corners of the connection points between the two side frames and the bottom frame are respectively provided with chamfers.

[0008] Specifically, the two side frames and the bottom frame are welded together as one unit, and the support plate is welded to the upper end of the side frame and the reinforcing beam respectively.

[0009] Furthermore, the bottom of the base frame and the reinforcing beam are each provided with multiple supports at equal intervals.

[0010] Furthermore, the top of each of the two side frames is provided with two sets of lifting rings for suspending the entire bracket.

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Combination Figure 1-3 As shown, a high-performance stainless steel pipe pickling tank 1 includes a support set inside the pickling tank 1. The support includes a base frame 2, two side frames 3 respectively disposed on both sides of the base frame 2, and a support plate 4 disposed on the two side frames 3 in a V-shape. A reinforcing beam 5 is provided in the middle of the base frame 2. The bottom of the bent part of the support plate 4 abuts against the top of the reinforcing beam 5. A set of long grooves 6 is provided on both sides of the support plate 4. The grooves in the two sets of long grooves 6 extend from one end of the support plate 4 toward the bent part of the support plate 4. The grooves in the two sets of long grooves 6 are staggered to disperse the placement of the grooves and prevent the support plate 4 from deforming and bending under force. The bottom frames 2 on both sides of the reinforcing beam 5 are also provided with filter screens 7, and the bottom of the bottom frame 2 and the bottom of the pickling tank 1 are set at a distance.

[0018] When pickling high-performance stainless steel pipes, the steel pipes are first placed into pickling tank 1. Bundles of steel pipes can be lifted into pickling tank 1 using a crane, or the steel pipes can be rolled into pickling tank 1 one by one using the slope of the two sides of the support and the guide platform. After the steel pipes are placed into pickling tank 1, they are stacked on the pallet 4 under their own weight. During pickling, as the pickling solution washes, impurities on the surface of the steel pipes fall through the long grooves 6 on the pallet 4 and are blocked by the filter screen 7 on the bottom frame 2 and remain on the filter screen 7. When the steel pipes have been pickled multiple times and a lot of impurities have accumulated on the filter screen 7, the support can be lifted out of the pickling tank 1 to clean the filter screen 7 and the entire support without having to empty the entire pickling tank 1 and clean the bottom of the pickling tank 1, which saves cleaning time. At the same time, since the steel pipes are stacked in a V-shape on the pallet 4, and the pallet 4 is equipped with two sets of long grooves 6, the steel pipes can also come into more effective contact with the pickling solution, improving the pickling effect.

[0019] In another embodiment, combined Figure 1-3 As shown, a support plate 8 is also provided at the bottom of each of the two trays 4 to ensure the strength of the trays 4.

[0020] In another embodiment, combined Figure 1-3 As shown, multiple support columns 9 are also connected between the two support plates 8 and the bottom frame 2 to further ensure the reliability of the support plate 4.

[0021] In another embodiment, the outer corners of the connection between the two side frames 3 and the bottom frame 2 are also chamfered to prevent the top edge of the pickling tank 1 from being damaged by bumps when the bracket is placed inside the pickling tank 1.

[0022] Specifically, the two side frames 3 and the bottom frame 2 are welded together, and the support plate 4 is welded to the upper end of the side frame 3 and the reinforcing beam 5 respectively.

[0023] In another embodiment, combined Figure 1 and Figure 3 As shown, the bottom of the base frame 2 and the reinforcing beam 5 are also provided with multiple supports 10 at equal intervals.

[0024] In another embodiment, the top of each of the two side frames 3 is provided with two sets of lifting rings 11 for suspending the entire bracket.

[0025] In another embodiment, filters 7 are provided between the two side frames 3 and between the two side frames 3 respectively, so as to prevent impurities from leaking out from the side frames 3 into the pickling tank 1 when the support is lifted.

[0026] In another embodiment, a reinforcing plate 12 is provided at the upper end of the bent portion of the pallet 4. The two sides of the reinforcing plate 12 are connected to the pallet 4 as a whole, and one end of each of the elongated grooves 6 extends to the pallet 4 below the reinforcing plate 12. Since the bending portion of the pallet 4 is subjected to the greatest force, the reinforcing plate 12 is provided to strengthen the strength of this position. At the same time, the elongated grooves 6 can prevent impurities from accumulating at the connection between the reinforcing plate 12 and the pallet 4.
