Electric telescopic columns 3 are fixed to the left and right ends of the top wall of the rust removal box 1. A fixing plate 4 is fixed to the lower surface of the electric telescopic column 3. A rust removal plate 5 is provided on the lower side of the fixing plate 4. Disassembly mechanisms 6 for disassembling the rust removal plate 5 are provided at the left and right ends of the front side of the fixing plate 4.

[0023] It should be noted that the fixing plate 4 and the rust removal plate 5 are driven downward to a suitable position by the electric telescopic column 3, so that the pressure vessel can be rust-removed.

[0024] See also Figure 2-3 In order to position the pressure vessel, the positioning mechanism 2 in this embodiment includes a motor 201 fixed to the bottom of the right side of the rust removal box 1. The bottoms of the opposite sides of the left and right side walls of the inner cavity of the rust removal box 1 are rotatably connected with a rotating shaft 202 through a bearing. The output shaft of the motor 201 passes through the right side wall of the inner cavity of the rust removal box 1 and extends to the inner cavity of the rust removal box 1 and is fixed to the right end rotating shaft 202. A rotating plate 203 is fixed on the opposite side of the two rotating shafts 202. When the motor 201 is started, the output shaft of the motor 201 rotates to drive the rotating shaft 202 at the right end to rotate. The rotation of the rotating shaft 202 at the right end can drive the rotating plate 203 to rotate. A clamping plate 204 is provided on the opposite side of the two rotating plates 203. The top is rotatably connected with a threaded rod 205 through a bearing, and the other end of the threaded rod 205 penetrates the rotating plate 203 and extends to a side away from the rotating plate 203. The threaded rods 205 on both sides are rotated, and the threaded rods 205 drive the clamping plate 204 to move to the side away from the rotating plate 203 when rotating. Slide blocks 206 are fixed to the lower surfaces of the two clamping plates 204, and support plates 207 are provided on the lower sides of the two clamping plates 204. The movement of the clamping plates 204 drives the sliders 206 to slide in the inner cavity of the support plates 207. The relative movement of the two clamping plates 204 can clamp the two ends of the pressure vessel. The rotation of the rotating plate 203 can drive the right end clamping plate 204 to rotate through the threaded rods 205, thereby rotating the pressure vessel.

[0025] Among them, a protective box is provided on the outer surface of the motor 201, and pulleys are fixed at the upper and lower ends of the two rotating plates 203 on the opposite sides. Circular grooves are opened on the opposite sides of the left and right side walls of the inner cavity of the protective box. The two pulleys make circular motion in the inner cavity of the circular grooves. Limit rods are fixed on the bottom of the opposite sides of the two clamping plates 204, and the opposite sides of the two limit rods penetrate the rotating plate 203 and extend to the side away from the rotating plate 203.

[0026] In this embodiment, the threaded rod 205 is threadedly connected to the rotating plate 203, a slide groove is provided on the upper surface of the support plate 207, and limiting grooves are provided on the opposite sides of the front and rear side walls of the inner cavity of the slide groove. The cross-sectional shape of the slider 206 is an inverted T shape, and the front and rear ends of the slider 206 both make horizontal linear motion in the inner cavity of the limiting groove.

[0027] It can be understood that by arranging the cooperation among the clamping plate 204, the threaded rod 205, the slider 206 and the support plate 207, the pressure vessels of different sizes can be positioned to avoid displacement during the rust removal process, thereby greatly improving the rust removal effect.

[0028] See also Figure 4 In order to facilitate the staff to disassemble the rust removal plate 5, the disassembly mechanism 6 in this embodiment includes a fixing groove 601 opened at the left and right ends of the front side of the fixing plate 4, a mounting plate 602 is fixed in the middle of the top wall of the fixing groove 601, telescopic rods 603 are fixed at the upper and lower ends of the left and right sides of the mounting plate 602, and movable plates 604 are fixed on the opposite sides of the telescopic rods 603 at the left and right ends. Insertion rods 605 are fixed at the upper and lower ends of the opposite sides of the two movable plates 604, and shifting blocks 606 are fixed on the tops of the two movable plates 604.

[0029] Among them, the two shift blocks 606 make relative movement or move away from each other in the inner cavity of the fixed groove 601, and the outer surface of the telescopic rod 603 is movably sleeved with a spring. The two shift blocks 606 are shifted toward one side of the mounting plate 602, and the movement of the shift blocks 606 drives the two movable plates 604 to move. The movement of the movable plates 604 will shorten the telescopic rod 603 and squeeze the spring. The two ends of the spring are respectively fixed between the opposite sides of the movable plate 604 and the mounting plate 602.

[0030] In addition, installation grooves are provided at both left and right ends of the upper surface of the rust removal plate 5, and slots compatible with the insertion rod 605 are provided at both upper and lower ends of the left and right side walls of the inner cavity of the installation groove, so that the insertion rod 605 can be moved out of the inner cavity of the slot until the insertion rod 605 is moved into the installation groove, the control of the rust removal plate 5 can be released, and then the rust removal plate 5 can be pulled downward to remove the rust removal plate 5.

[0031] The working principle of the above embodiment is:

[0032] (1) When positioning the pressure vessel, first place the pressure vessel on the upper surface of the support plate 207, then rotate the threaded rods 205 on both sides. When the threaded rods 205 rotate, they drive the clamping plate 204 to move to the side away from the rotating plate 203. The movement of the clamping plate 204 drives the limit rod to extend, so that the movement of the clamping plate 204 can be limited. The movement of the clamping plate 204 drives the slider 206 to slide in the inner cavity of the support plate 207. The relative movement of the two clamping plates 204 can clamp the two ends of the pressure vessel, and then start the motor. 201, the output shaft of the motor 201 rotates and drives the right end shaft 202 to rotate, the rotation of the right end shaft 202 can drive the rotating plate 203 to rotate, when the rotating plate 203 rotates, the fixed pulley on the right side rotates in the inner cavity of the circular groove, so that the rotating plate 203 can rotate stably, the rotation of the rotating plate 203 can drive the right end clamping plate 204 to rotate through the threaded rod 205, and then the pressure vessel can be rotated, and the fixed plate 4 and the rust removal plate 5 can be driven downward to a suitable position by the electric telescopic column 3, so that the pressure vessel can be derusted.

[0033] (2) Suitable rust removal plates 5 can be replaced for pressure vessels of different sizes to improve the efficiency of rust removal. When removing the rust removal plate 5, first push the two push blocks 606 toward one side of the mounting plate 602. The movement of the push blocks 606 drives the two movable plates 604 to move. The movement of the movable plates 604 shortens the telescopic rod 603 and squeezes the spring, thereby allowing the insertion rod 605 to move out of the inner cavity of the slot until the insertion rod 605 moves into the mounting slot. The control of the rust removal plate 5 can then be released. Then, the rust removal plate 5 can be removed by pulling it downward.
