[0043] Embodiment 2: Considering that the stainless steel flange pipe is composed of a pipe and a flange plate welded together, welding slag is usually left at the welding point between the pipe and the flange plate of the flange pipe. Since the welding slag is closely attached to the outer surface of the flange pipe, the welding slag is usually cleaned off by knocking, which causes the flange pipe to be easily scratched during the knocking process. The scratches will make the flange pipe susceptible to pitting and rust, affecting the appearance quality of the flange pipe. In view of the above problems, the embodiment of the present application adds a connecting rod 309 and a rotating seat 310 on the basis of the above embodiment, specifically: like Figure 1 , Figure 2 , Figure 8 and Fig. 9As shown, the cleaning assembly 300 also includes a connecting rod 309 and a rotating seat 310; a plurality of rotating seats 310 are fixed at the bottom of the sliding block 303, and the cleaning nozzle 304 is rotatably connected to the rotating seat 310, and the cleaning nozzle 304 can rotate toward the moving direction of the sliding block 303, and the cleaning nozzle 304 is connected to the connecting cavity 308 in the sliding block 303 through the rotating seat 310; the cleaning nozzle 304 can contact the side wall of the flange plate welded at both ends of the flange pipe when the sliding block 303 moves to the end of the flange pipe, and when the sliding block 303 moves forward, the flange plate pushes the cleaning nozzle 304 to rotate, so that the cleaning nozzle 304 rotates to a vertical state, at which time the water spray port of the cleaning nozzle 304 faces the welding part of the flange pipe, and the cleaning nozzle 304 follows the circular shape of the flange pipe The cleaning nozzles 304 are arranged in sequence in the circumferential direction. When the cleaning nozzle 304 rotates to a vertical state, the water outlet of the cleaning nozzle 304 faces the connection between the pipe and the flange of the flange pipe, thereby cleaning the welding slag generated by the welding at the connection. The connecting rods 309 are respectively fixedly connected to the side walls of the cleaning nozzles 304. The connecting rods 309 fix the cleaning nozzles 304 together. When the cleaning nozzles 304 and the flange are in contact, the cleaning nozzles 304 can rotate together. When the cleaning nozzles 304 rotate to a vertical state, the moving motor 307 stops running, so that the sliding block 303 stops moving, and then the cleaning nozzles 304 continue to spray water to the pipe and the flange welding of the flange pipe. The cooling water mixed with metal powder can wash down the welding slag on the surface of the flange pipe.

[0044] Preferably, Figure 8 and Fig. 9 As shown, there are three cleaning nozzles 304, and the length of the cleaning nozzle 304 located in the middle position is shorter than that of the cleaning nozzles 304 on both sides. When cleaning the outside of the flange pipe, the angles between the cleaning nozzle 304 and the outer wall of the flange pipe are different, so that the water pressures sprayed onto the surface of the flange pipe by different cleaning nozzles 304 are different, and the dirt attached to the surface of the flange pipe that is difficult to clean can be cleaned off. When the cleaning nozzle 304 moves to the welding position of the flange and the pipeline, the direction in which the cleaning nozzle 304 located in the middle position sprays cooling water is perpendicular to the axis of the flange pipe. At this time, the impact force of the cooling water on the surface of the flange pipe is the greatest, so that the welding slag tightly attached to the flange pipe is loosened. The cleaning nozzles 304 located on both sides can clean the loosened welding slag on the flange pipe when the flange pipe rotates, thereby cleaning the welding slag generated during the welding of the flange pipe.

[0045] Preferably, the cleaning nozzle 304 rotates at an angle of 45° to 135°, and the direction in which the cleaning nozzle 304 rotates is the moving direction of the sliding block 303 .

[0046] Preferably, the sliding block 303 drives the moving block 206 to move back and forth on the support plate 102 through the forward and reverse rotation of the moving motor 307. Before the sliding block 303 moves in the opposite direction, the sliding block 303 continues to move forward along the guide rail 305, so that the flange pushes the cleaning nozzle 304 to rotate to 135°, and then the sliding block 303 moves in the opposite direction driven by the moving motor 307, so that the cleaning nozzle 304 is always inclined 45° in the moving direction of the sliding block 303. After the cleaning nozzle 304 contacts the flange on the flange pipe, the flange pushes the cleaning nozzle 304 to rotate, while cleaning the dirt on the surface of the flange pipe, avoiding excessive pressure of the sprayed water flow to damage the flange pipe.

[0047] Preferably, the water outlet diameter of the cleaning nozzle 304 located in the middle position on the sliding block 303 is smaller than the water outlet diameters of the other two nozzles, so that the water pressure sprayed from the cleaning nozzle 304 in the middle position is greater than that of the other two cleaning nozzles 304. The cooling water sprayed from the cleaning nozzle 304 can loosen the tightly adhered welding slag, thereby facilitating the cleaning of the welding slag.

[0048] Preferably, the connecting rod 309 is a rectangular rod, and the connecting rod 309 fixedly connects the cleaning nozzles 304 together. When the cleaning nozzles 304 rotate, the rotation angles of each cleaning nozzle 304 can be the same.

[0049] Preferably, a spherical chamber connected to the connecting chamber 308 is opened in the rotating seat 310, and the part of the cleaning nozzle 304 located in the rotating seat 310 is a sphere with an open top. When the cleaning nozzle 304 rotates, the cooling water in the connecting chamber 308 can enter the cleaning nozzle 304 through the spherical chamber in the rotating seat 310, and then be sprayed onto the surface of the flange pipe by the cleaning nozzle 304.

[0050] In actual use, based on the above embodiment, when the sliding block 303 drives the cleaning nozzle 304 to move, the cleaning nozzle 304 sprays cooling water onto the surface of the flange pipe. When the sliding block 303 moves to the end of the flange pipe, the sliding block 303 continues to move forward, so that the flange pushes the cleaning nozzle 304 to rotate. When the cleaning nozzle 304 rotates to a state perpendicular to the axis of the flange pipe, the cooling water pressure sprayed from the cleaning nozzle 304 is the largest, which can clean up the welding slag attached to the welding part of the flange pipe. When cleaning some welding slag that is difficult to clean up, the sliding block 303 stops. Move forward so that the cleaning nozzle 304 continues to spray cooling water onto the welding point of the flange pipe. After the welding slag is cleaned, the sliding block 303 continues to move forward so that the flange plate continues to push the cleaning nozzle 304 to rotate. When the cleaning nozzle 304 rotates to the extreme position, the moving motor 307 drives the sliding block 303 to move in the opposite direction, and the cleaning nozzle 304 cleans the outer surface of the flange pipe again, thereby cleaning the dirt remaining on the surface of the flange pipe. When the sliding block 303 moves to the other end of the flange pipe, the cleaning nozzle 304 cleans the welding slag at the welding point of the other end of the flange pipe.

[0052] Preferably, a water inlet 104 connected to the interior of the storage chamber 315 is provided on the side wall of the sliding block 303 for replenishing the nitric acid solution into the sliding block 303. The water inlet 104 is closed by a screw cap to prevent the nitric acid solution in the storage chamber 315 from spilling out during the movement of the sliding block 303.

[0053] Preferably, the rotating plate 312 is a pair of rectangular plates, and the rotating plates 312 are respectively located on both sides of the cleaning nozzle 304. When the cleaning nozzle 304 rotates, it can contact the rotating plate 312. The rotating direction of the rotating plate 312 is the same as the moving direction of the sliding block 303. When the rotating plate 312 contacts the flange, the cleaning nozzle 304 can be pushed to rotate by the rotating plate 312. A groove is opened on the rotating plate 312, and the sponge block 313 is fixed in the groove on the rotating plate 312; the sponge block 313 is fixed on the rotating plate 312 near the cleaning nozzle 304. 4, when the sliding block 303 moves to the end of the flange pipe, the flange and the rotating plate 312 contact to make the rotating plate 312 rotate, and under the push of the rotating plate 312, the cleaning nozzle 304 contacts the sponge block 313 on the other rotating plate 312 to squeeze out the nitric acid solution temporarily stored in the sponge block 313. At this time, the cleaning nozzle 304 is at the welding place between the pipe and the flange on the flange pipe, and the nitric acid solution and the cooling water sprayed from the cleaning nozzle 304 are mixed and sprayed onto the welding place of the flange pipe. The nitric acid solution can make the welding slag fall off from the flange pipe more easily.

[0054] Preferably, the rotating shaft of the rotating plate 312 is a spring shaft, and the rotating plate 312 can rotate under the push of external force.

[0057] Preferably, when the sliding block 303 moves, the rectangular opening and the rectangular channel on the same side of the moving direction are staggered, so that the nitric acid solution in the storage chamber 315 will not flow out, and the rectangular opening and the rectangular channel on the other side of the cleaning nozzle 304 are aligned, so that the nitric acid in the storage chamber 315 can easily flow to the bottom of the sliding block 303, and then be absorbed by the sponge block 313, and the sponge block 313 smears the nitric acid solution on the surface of the flange pipe.

[0058] Preferably, the sponge block 313 is a high-density polyethylene sponge.

[0059] Preferably, the length of the guide rail 305 is longer than the length of the flange tube by the length of two sliding blocks 303. When the sliding block 303 moves to the end of the flange tube, it can continue to move forward. During the movement, the flange plate contacts the cleaning nozzle 304, causing the cleaning nozzle 304 to rotate. At the same time, the movable plate 311 can contact the limit blocks at both ends of the guide rail 305. The limit blocks push the movable plate 311 to slide in the sliding block 303, thereby controlling the outlet of the storage chamber 315. During the reciprocating movement of the sliding block 303, the sponge block 313 located at the rear side of the cleaning nozzle 304 always applies nitric acid solution to the flange tube.

[0060] Preferably, if the oxide layer on the surface of the flange pipe is thick, the sliding block 303 stops moving after moving from one end of the flange pipe to the other end. After standing for 3 to 5 minutes, the sliding block 303 moves in the opposite direction, which can leave time for a chemical reaction between the nitric acid solution and the oxide layer on the surface of the flange pipe, thereby improving the cleaning effect of the oxide layer.

The opening and closing of the rectangular channel in the sliding block 303 are controlled by the movable plate 311. When the sliding block 303 moves forward, the movable plate 311 opens the rectangular channel located at the rear side of the cleaning nozzle 304, and the sponge block 313 located at the rear side of the cleaning nozzle 304 absorbs the nitric acid solution and then applies it to the outer surface of the flange tube. The nitric acid solution and the dirt and oxides on the surface of the flange tube send out a chemical reaction, so that the oxides and dirt are easily cleaned off. When the sliding block 303 moves from When one end of the flange pipe moves to the other end, the sliding block 303 continues to move forward, causing the rotating plate 312 to push the cleaning nozzle 304 to rotate. The rotation of the cleaning nozzle 304 will contact the sponge block 313 on the other rotating plate 312. The sponge block 313 will be squeezed to squeeze out the nitric acid solution stored inside. At the same time, the movable plate 311 contacts the limit block at the end of the guide rail 305, so that the rectangular channel previously connected to the storage chamber 315 is closed, while the rectangular channel on the other side connected to the storage chamber 315 is opened. Then the moving block 206 moves in the opposite direction, and the cooling water sprayed from the cleaning nozzle 304 cleans the dirt and oxide layer on the surface of the flange pipe. After the oxide layer is removed, the dirt loses its attachment point on the surface of the flange pipe, ensuring that the cleaned flange pipe is not easy to adhere to dirt.
