DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1, reference Figure 1-3 A welding pipe drying device includes a pickling box 2, a feeding port 1 and a discharge port 8 opened on the side of the pickling box 2. A stepper motor 19 is installed on the back of the pickling box 2. The end of the output shaft of the stepper motor 19 is connected to a disc 16. A plurality of placement grooves 3 are evenly opened at the circumferential position of the disc 16. A welding pipe 4 is placed inside the placement groove 3.

[0034] A drying component 6 is installed at the position of the discharge port 8, and the drying component 6 includes a discharge plate 61, a slot 62, a protrusion 63 and a collecting chamber 64. The discharge plate 61 is obliquely installed on the pickling box 2 at the lower end of the discharge port 8, and the slots 62 are distributed in an array on the discharge plate 61. The collecting chamber 64 is located on the inner side of the discharge plate 61, and the collecting chamber 64 is connected with the slots 62. A protrusion 63 is provided on the discharge plate 61 above each slot 62, and the upper end of the protrusion 63 is arranged in an arc shape.

[0035] A support frame 5 is installed on the pickling box 2 at the upper end of the discharge port 8, and a baffle 7 is connected to one side of the support frame 5 through an electric telescopic rod 25, and the position of the baffle 7 matches the position of the discharge port 8.

[0036] The oxide scale on the surface of the welded pipe 4 is mainly formed due to the high-temperature oxidation reaction during the welding process. During the welding process, the surface of the welded pipe 4 will react with the oxygen in the air to form an oxide layer, namely, an oxide scale. This oxide scale usually appears as a layer of black or dark brown solid substance. The oxide scale will form tiny cracks or pores. These cracks and pores will make the surface of the welded pipe more susceptible to corrosion and contamination, thereby increasing the corrosion risk of the welded pipe.

[0037] To this end, the welded pipe 4 that has completed the welding process is introduced from the feed port 1, and the stepper motor 19 drives the disc 16 inside the pickling box 2 to rotate. A placement slot 3 is arranged on the outside of the disc 16. The welded pipe 4 will enter different placement slots 3 in turn. As the disc 16 rotates, the position of the placement slot 3 rotates synchronously. At this time, the welded pipe 4 on the inside of the placement slot 3 moves due to the inner wall of the pickling box 2, so that the welded pipe 4 can rotate relative to the pickling box 2. The bottom of the pickling box 2 and the inner side of the containing box 9 are filled with an acid solution. When the welded pipe 4 rotates to the upper end of the containing box 9, it contacts the acid solution to achieve pickling of the welded pipe. When the welded pipe 4 moves to the position of the discharge port 8 after pickling, the welding pipe 4 is started. The switch of the electric telescopic rod 25 is turned on to remove the baffle 7 blocking the discharge port 8, so that the welding pipe 4 located inside the placement groove 3 can fall smoothly on the discharge plate 61. When the welding pipe 4 rolls on the discharge plate 61 by its own gravity, a plurality of protrusions 63 with arc-shaped upper ends are provided on the discharge plate 61. When the welding pipe 4 contacts the protrusions 63, the welding pipe 4 will jump upward when passing through the protrusions 63. During the whole process, the welding pipe 4 is in a bumpy state, which will shake off the water and impurities attached to its surface. At the same time, the fallen water and impurities will enter the inner side of the collection chamber 64 below along the slot hole 62 for centralized collection to prevent a large amount of water from accumulating on the surface of the discharge plate 61.

[0038] Example 2, reference Figure 4-5 The difference between this embodiment and embodiment 1 is that a through hole 15 is provided on the other side of the pickling box 2, and two frames 24 are symmetrically arranged on the outside of the through hole 15. A circular shaft 13 is rotatably arranged between the two frames 24, and both ends of the circular shaft 13 extend to the other side of the frames 24. Welded pipe surface treatment components are provided at both ends of the circular shaft 13, and a transmission member is installed at one end of the circular shaft 13.

[0039] The welded pipe surface treatment assembly includes a first connecting rod 10, an oscillation assembly 11, a second connecting rod 12 and a containing box 9 installed at the lower end of the pickling box 2. The oscillation assembly 11 includes a tuning fork 1101, a connecting rope 1102, a round rod 1103 and a metal ball 1104; the connecting rope 1102 is connected to the round rod 1103, and the metal ball 1104 is fixed to the bottom of the connecting rope 1102. The tuning forks 1101 are symmetrically installed at the bottom of the containing box 9, and the metal ball 1104 is located between the two tuning forks 1101.

[0040] refer to Figure 8-9A sealed bearing 22 is installed on one side of the containing box 9, and one end of the round rod 1103 passes through the sealed bearing 22 and extends to the inner side of the containing box 9, a straight plate 21 is installed on one side of the containing box 9, and an elastic column 23 is connected between the straight plate 21 and the round rod 1103 at the upper end, the lower end of the first connecting rod 10 is movably connected to the round rod 1103, the first connecting rod 10 is connected to the second connecting rod 12 through a hinge, the other end of the second connecting rod 12 is sleeved on the round shaft 13, and the length of the second connecting rod 12 is less than the length of the first connecting rod 10.

[0041] There are tiny gaps in the oxide scale on the outside of the welded pipe 4. When the welded pipe 4 is immersed in an acidic solution, due to the cohesive force between the liquid molecules, the surface of the liquid tends to shrink like an elastic film. When the liquid tries to enter the narrow gaps, this surface tension prevents the liquid from further penetrating. Therefore, it is not easy for the acidic solution to enter the gaps in the oxide scale.

[0042] In order to allow the acidic solution to smoothly enter the tiny gaps in the oxide scale, a rocker structure consisting of a first connecting rod 10 and a second connecting rod 12 is arranged at both ends of the circular shaft 13. The structure drives the round rod 1103 located on both sides of the containing box 9 to swing periodically. At the same time, the junction of the round rod 1103 and the containing box 9 is connected by a spherical sealing bearing 22, which plays a sealing role while cooperating with the movement of the round rod 1103. When the round rod 1103 swings periodically, it drives the connecting rope 1102 and the metal ball 1104 fixed at its end position to swing together. When the metal ball 1104 collides with the tuning forks 1101 on both sides, the tuning forks 1101 will vibrate, and the acidic solution will vibrate during the vibration. With the help of the vibration generated, the intermolecular force in the liquid is destroyed, so that the liquid molecules can smoothly enter the tiny gaps in the oxide scale, achieve comprehensive contact with the oxide scale, and remove the oxide scale on the surface of the welding pipe 4.

[0043] Example 3, reference Figure 4 and Figure 7 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the transmission member includes an output shaft installed on a stepper motor 19 and a transmission wheel 18 on a circular shaft 13, a chain 17 is sleeved on the outer side of the two transmission wheels 18, a plurality of wave bars 14 are evenly installed on the outer side of the circular shaft 13, the wave bar 14 includes a sleeve 1402 arranged on the outer side of the circular shaft 13, a metal rope 1401 is installed at one end of the sleeve 1402, and when the metal rope 1401 rotates, the end of the metal rope 1401 passes through the through hole 15 and contacts with the welding pipe 4 inside the pickling box 2.

[0044] When the oxide scale formed on the surface of the welded pipe 4 contacts the acidic solution, a chemical reaction occurs, which reacts away the oxide scale on the outside. Since the inside is not in contact with the acidic solution, part of the oxide scale remains on the outside of the welded pipe 4, and the oxide scale wrapped around the outside that has reacted should be exposed in time.

[0045] To this end, a plurality of groups of toggle bars 14 are arranged on the outside of the circular shaft 13. As the circular shaft 13 rotates, the external toggle bars 14 rotate synchronously. During the rotation process, the end position of the toggle bars 14 keeps contacting with the outer surface of the welding pipe 4. When the welding pipe 4 moves inside the pickling tank 2, relative slippage may occur between the inner wall of the pickling tank 2 and the welding pipe 4, so that when each welding pipe 4 reaches the position of the through hole 15, the surface in contact with the toggle bars 14 is different. With the help of the metal rope 1401 on the toggle bars 14 and the welding pipe 4, the welding pipe 4 can be moved to the outside of the circular shaft 13. The surface contact can effectively beat off the oxide scale on the outside of the welding pipe 4 after the reaction, and expose the oxide scale inside. At the same time, the length of the through hole 15 is smaller than the length of the welding pipe 4, so the welding pipe 4 will not roll down when passing through the through hole 15. The metal rope 1401 is woven from several strands of metal wires and thin ropes, which are twisted into a rope and fixed to one end of the sleeve 1402. The combination of the sleeve 1402 and the metal rope 1401 can shorten the length of the metal rope 1401, which can prevent the problem of the metal rope 1401 being entangled.

[0046] The circular shaft 13 obtains kinetic energy through the cooperation of two transmission wheels and the chain 17 , and the rotation speed of the circular shaft 13 is greater than the rotation speed of the circular disc 16 .

[0047] Example 4, reference Figure 6 The difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is that a plurality of limit rods 27 are installed in parallel to the upper end of the containing box 9, and the limit rods 27 are in contact with the disc 16, and a crushing assembly 26 is arranged between the lower parts of the limit rods 27.

[0048] The crushing assembly 26 includes a partition 2601, a hole 2602 and a metal needle 2603. The partition 2601 is horizontally arranged between the lower parts of the plurality of limit rods 27. The holes 2602 are distributed in an array on the partition 2601. The metal needle 2603 is evenly installed at the lower part of the partition 2601.

[0049] During the vibration of tuning fork 1101, some bubbles will be generated. The bubbles in the liquid will reduce the fluidity of the liquid because the presence of bubbles will affect the surface tension of the liquid. Surface tension is the interaction force between molecules on the gas-liquid interface, which is manifested as a tension layer quasi-perpendicular to the interface. The presence of surface tension not only makes the liquid surface show contraction characteristics, but also determines the shape and behavior of bubbles in the liquid. When bubbles exist, the tension distribution on the liquid surface will change, thereby affecting the fluidity of the liquid.

[0050] To this end, at the upper port of the containing box 9, not only are multiple limit rods 27 provided, the limit rods 27 can prevent the welding pipe 4 from falling to the inner side of the containing box 9 during rotation, but also a crushing assembly 26 arranged between the lower ends of the limit rods 27 is composed of a partition 2601, a hole 2602 and a metal needle 2603. When the bubbles rise, the metal needle 2603 will puncture the bubbles during contact with the bubbles, and the hole 2602 can enable the liquid on the upper and lower sides of the partition 2601 to circulate. At the same time, when the bubbles are punctured, not only can the fluidity of the liquid be improved, but also local turbulence and vortexes can be generated when the bubbles are broken, which can further improve the fluidity of the liquid.

[0051] The working principle of the device is:

[0052] The oxide scale on the surface of the welded pipe 4 is mainly formed due to the high-temperature oxidation reaction during the welding process. During the welding process, the surface of the welded pipe 4 will react with the oxygen in the air to form an oxide layer, namely, an oxide scale. This oxide scale usually appears as a layer of black or dark brown solid substance. The oxide scale will form tiny cracks or pores. These cracks and pores will make the surface of the welded pipe more susceptible to corrosion and contamination, thereby increasing the corrosion risk of the welded pipe.

[0053] To this end, the welded pipe 4 that has completed the welding process is introduced from the feed port 1, and the stepper motor 19 drives the disc 16 inside the pickling box 2 to rotate. A placement slot 3 is arranged on the outside of the disc 16. The welded pipe 4 will enter different placement slots 3 in turn. As the disc 16 rotates, the position of the placement slot 3 rotates synchronously. At this time, the welded pipe 4 on the inside of the placement slot 3 moves due to the inner wall of the pickling box 2, so that the welded pipe 4 can rotate relative to the pickling box 2. The bottom of the pickling box 2 and the inner side of the containing box 9 are filled with an acid solution. When the welded pipe 4 rotates to the upper end of the containing box 9, it contacts the acid solution to achieve pickling of the welded pipe. When the welded pipe 4 moves to the position of the discharge port 8 after pickling, the welding pipe 4 is started. The switch of the electric telescopic rod 25 is turned on to remove the baffle 7 blocking the discharge port 8, so that the welding pipe 4 located inside the placement groove 3 can fall smoothly on the discharge plate 61. When the welding pipe 4 rolls on the discharge plate 61 by its own gravity, a plurality of protrusions 63 with arc-shaped upper ends are provided on the discharge plate 61. When the welding pipe 4 contacts the protrusions 63, the welding pipe 4 will jump upward when passing through the protrusions 63. During the whole process, the welding pipe 4 is in a bumpy state, which will shake off the water and impurities attached to its surface. At the same time, the fallen water and impurities will enter the inner side of the collection chamber 64 below along the slot hole 62 for centralized collection to prevent a large amount of water from accumulating on the surface of the discharge plate 61.

[0054] There are tiny gaps in the oxide scale on the outside of the welded pipe 4. When the welded pipe 4 is immersed in an acidic solution, due to the cohesive force between the liquid molecules, the surface of the liquid tends to shrink like an elastic film. When the liquid tries to enter the narrow gaps, this surface tension prevents the liquid from further penetrating. Therefore, it is not easy for the acidic solution to enter the gaps in the oxide scale.

[0055] In order to allow the acidic solution to smoothly enter the tiny gaps in the oxide scale, a rocker structure consisting of a first connecting rod 10 and a second connecting rod 12 is arranged at both ends of the circular shaft 13. The structure drives the round rod 1103 located on both sides of the containing box 9 to swing periodically. At the same time, the junction of the round rod 1103 and the containing box 9 is connected by a spherical sealing bearing 22, which plays a sealing role while cooperating with the movement of the round rod 1103. When the round rod 1103 swings periodically, it drives the connecting rope 1102 and the metal ball 1104 fixed at its end position to swing together. When the metal ball 1104 collides with the tuning forks 1101 on both sides, the tuning forks 1101 will vibrate, and the acidic solution will vibrate during the vibration. With the help of the vibration generated, the intermolecular force in the liquid is destroyed, so that the liquid molecules can smoothly enter the tiny gaps in the oxide scale, achieve comprehensive contact with the oxide scale, and remove the oxide scale on the surface of the welding pipe 4.

[0056] During the vibration of tuning fork 1101, some bubbles will be generated. The bubbles in the liquid will reduce the fluidity of the liquid because the presence of bubbles will affect the surface tension of the liquid. Surface tension is the interaction force between molecules on the gas-liquid interface, which is manifested as a tension layer quasi-perpendicular to the interface. The presence of surface tension not only makes the liquid surface show contraction characteristics, but also determines the shape and behavior of bubbles in the liquid. When bubbles exist, the tension distribution on the liquid surface will change, thereby affecting the fluidity of the liquid.

[0057] To this end, at the upper port of the containing box 9, not only are multiple limit rods 27 provided, the limit rods 27 can prevent the welding pipe 4 from falling to the inner side of the containing box 9 during rotation, but also a crushing assembly 26 arranged between the lower ends of the limit rods 27 is composed of a partition 2601, a hole 2602 and a metal needle 2603. When the bubbles rise, the metal needle 2603 will puncture the bubbles during contact with the bubbles, and the hole 2602 can enable the liquid on the upper and lower sides of the partition 2601 to circulate. At the same time, when the bubbles are punctured, not only can the fluidity of the liquid be improved, but also local turbulence and vortexes can be generated when the bubbles are broken, which can further improve the fluidity of the liquid.

[0058] When the oxide scale formed on the surface of the welded pipe 4 contacts the acidic solution, a chemical reaction occurs, which reacts away the oxide scale on the outside. Since the inside is not in contact with the acidic solution, part of the oxide scale remains on the outside of the welded pipe 4, and the oxide scale wrapped around the outside that has reacted should be exposed in time.

[0059] To this end, a plurality of groups of toggle bars 14 are arranged on the outside of the circular shaft 13. As the circular shaft 13 rotates, the external toggle bars 14 rotate synchronously. During the rotation process, the end position of the toggle bars 14 keeps contacting with the outer surface of the welding pipe 4. When the welding pipe 4 moves inside the pickling tank 2, relative slippage may occur between the inner wall of the pickling tank 2 and the welding pipe 4, so that when each welding pipe 4 reaches the position of the through hole 15, the surface in contact with the toggle bars 14 is different. With the help of the metal rope 1401 on the toggle bars 14 and the welding pipe 4, the welding pipe 4 can be moved to the outside of the circular shaft 13. The surface contact can effectively beat off the oxide scale on the outside of the welding pipe 4 after the reaction, and expose the oxide scale inside. At the same time, the length of the through hole 15 is smaller than the length of the welding pipe 4, so the welding pipe 4 will not roll down when passing through the through hole 15. The metal rope 1401 is woven from several strands of metal wires and thin ropes, which are twisted into a rope and fixed to one end of the sleeve 1402. The combination of the sleeve 1402 and the metal rope 1401 can shorten the length of the metal rope 1401, which can prevent the problem of the metal rope 1401 being entangled.

[0060] The circular shaft 13 obtains kinetic energy through the cooperation of two transmission wheels and the chain 17 , and the rotation speed of the circular shaft 13 is greater than the rotation speed of the circular disc 16 .

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
