fig. 2 is a schematic structural view of the tube rack of the present invention.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Referring to fig. 1 and 2, an acid circulation pickling tank for pickling stainless steel seamless pipes comprises a tank body 1, wherein a fixed frame 2 is arranged above the tank body 1, a plurality of pairs of hoisting hoists 3 are arranged at the top of the fixed frame 2, a pipe placing frame is hung below the hoisting hoists 3 and consists of a frame body 4 and a plurality of pipe placing pipes 5 arranged on the frame body 4, a plurality of steel pipe brackets 6 are equidistantly arranged in the pipe placing pipes 5, the steel pipe brackets 6 are annular formed by bending wavy steel plates, the stainless steel seamless pipes 7 to be processed are inserted into the steel pipe brackets 6, one end of each pipe placing pipe 5 is provided with an acid injection interface 8, the other end of each pipe placing pipe 5 is provided with a filter screen 9, the middle part of each filter screen 9 is provided with a connecting column 10, one end of each connecting column 10 is inserted into the stainless steel seamless pipe 7 and is provided with an elastic support sheet 11, the two ends of the elastic support sheet 11 are abutted against the inner wall of the stainless steel seamless tube 7, the other end of the connecting column 10 penetrates out of the filter screen 9, the lower end of the tube placing frame is connected with a plurality of pairs of telescopic rods 12, the bottom of each telescopic rod 12 is fixed in the cell body 1, one side of the cell body 1 is provided with a small cell 13, the cell body 1 and the small cell 13 are communicated through a connecting hole 14, a partition plate 15 is further arranged in the small cell 14, one side of the partition plate 15 is further provided with a pump body 16, the pump body 16 is connected with each acid liquor injection port 8 through a connecting pipe 17, and the top of the small cell 13 above the pump body 16 is further provided with a feeding mechanism 18.
