Description

Technical Field

[0001] The invention relates to the technical field of galvanized pipe processing, in particular to a production device for corrosion-resistant galvanized pipes. Background Art

[0002] Hot-dip galvanizing pipes are made by reacting molten metal with iron matrix to produce alloy layer, so that the matrix and coating are combined, so it has strong corrosion resistance. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the rust on the surface of the steel pipe, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot dip plating tank for solvent treatment.

[0003] According to a disclosed galvanized pipe production solvent treatment device (publication number: CN110699623A), in the above application, by setting up an air-drying mechanism, high-pressure air is blown into the galvanized pipe from an inner cold air duct to remove excess zinc layer inside the steel pipe, high-pressure hot air is blown into the galvanized pipe from an inner hot air duct to remove excess zinc layer inside the steel pipe again, and high-pressure air is blown to the outer surface of the galvanized pipe by an outer hot air duct to remove excess zinc layer inside the steel pipe again, so that the thickness of the galvanized layer on the inner and outer walls of the galvanized pipe is uniform, thereby ensuring the quality of the galvanized pipe.

[0004] However, during the actual use of the above equipment, during the blowing operation, the galvanized pipe and the blowing equipment are in a relatively static state, and the wind source is also relatively static, which makes the airflow direction approximately consistent. This can easily lead to uneven distribution of excess zinc layer removed by blowing in the galvanized pipe, reducing the overall processing quality of the galvanized pipe.

In addition, the hot air blower 3 is electrically connected to the external mains electricity, thereby providing the hot air blower 3 with a stable power output to ensure that the hot air blower 3 can continuously blow outwards. At the same time, a vertical plate for rotating the blower 4 is provided on the upper surface of the workbench 1. Specifically, the blower 4 penetrates through and is rotatably mounted on the vertical plate. Furthermore, the output shaft 6 rotates away from one end of the variable frequency motor 5. The mounting plate is dynamically connected to ensure that the output shaft 6 always maintains a horizontal state during high-speed rotation, avoiding affecting the stable transmission effect of the pinion 7. At the same time, the pinion 7 is meshed with the gear ring 8 to realize transmission, and the gear ring 8 and the hair dryer 4 are in a relatively fixed state. Specifically, when the frequency conversion motor 5 is started, the output shaft 6 is cooperated so that when the pinion 7 rotates, the gear ring 8 drives the hair dryer 4 to rotate. At this time, the rotation direction of the hair dryer 4 is opposite to the rotation direction of the pinion 7. Furthermore, the hair dryer 4 is arranged in a trumpet shape, including a large diameter end and a small diameter end. The small diameter end is arranged close to the hot air blower 3, and the large diameter end is arranged as a straight section, and the small diameter end is arranged as an inclined section, so as to better limit the direction of the airflow blown out of the hair dryer 4, avoid its excessive escape, and affect the blowing effect of the hot air blown out of the hair dryer 4 on the galvanized pipe.

[0032] In an embodiment of the present invention, multiple groups of receiving grooves, fixed shafts 9 and guide plates 10 are provided, and the multiple groups of receiving grooves, fixed shafts 9 and guide plates 10 are evenly distributed on the inner wall of the hair dryer 4 in a circular array. Specifically, the multiple groups of receiving grooves, fixed shafts 9 and guide plates 10 are arranged on the inner surface of the inclined portion at the left end of the hair dryer 4, so that the airflow entering the hair dryer 4 can be better affected by the guide plates 10 during the diffusion process and change the direction of movement, thereby better achieving the effects of turbulence and changing the direction of the airflow, and improving the operation effect of the hair dryer 4 in blowing out hot air. At the same time, a circular hole with a diameter matching the outer diameter of the fixed shaft 9 is opened on the inner wall of the guide plate 10 to facilitate the installation of the fixed shaft 9 and facilitate the relative rotation between the guide plate 10 and the fixed shaft 9.

[0033] In addition, in order to further enhance the effect of the guide plate 10 on changing the wind direction, a toggle mechanism is arranged above the workbench 1, and the toggle mechanism includes a toggle wheel 11.

A transmission cavity is opened inside the toggle wheel 11, and a driving gear 12 is sleeved on the outer wall of the output shaft 6. A driven gear 13 is rotatably installed on the inner surface of the transmission cavity. A toggle rod 14 passes through the inner wall of the hair dryer 4, and the toggle rod 14 is slidably connected to the hair dryer 4. A volute spring 15 is sleeved on the arc-shaped outer wall of the fixed shaft 9.

Specifically, the driving gear 12 is meshed with the driven gear 13 to achieve transmission, and the arc-shaped inner wall of the transmission cavity set in the disc shape is provided with a tooth pattern that can mesh with the driven gear 13 to achieve transmission, so that when the frequency conversion motor 5 drives the output shaft 6 to rotate, the driving gear 12 and the driven gear 13 are matched to make the toggle wheel The toggle wheel 11 rotates at a speed lower than the rotation speed of the output shaft 6. Specifically, due to the transmission relationship between the positioning plate and the toggle wheel 11, the toggle wheel 11 can achieve relative rotation with the output shaft 6. Further, the toggle wheel 11 is configured as a wheel disk with four arc-shaped protrusions, so that the toggle wheel 11 can toggle four times to a target position when it rotates one circle, thereby improving the efficiency of the toggle wheel 11 in triggering the toggle effect. At the same time, the toggle rod 14 is disposed on the inclined section of the hair dryer 4, but the toggle rod 14 itself is always The hair dryer 4 is in a vertical state, and the inner wall of the inclined section is provided with a socket adapted to the outer diameter of the lever 14, thereby limiting the movement trajectory of the lever 14 and making it always slide along the socket. Specifically, the lever 14 is arranged in an arc shape at one end away from the center of the hair dryer 4, so that the protrusion of the toggle wheel 11 can be more smoothly in contact with it without getting stuck. In addition, the bottom end of the lever 14 is hinged to the inner wall of the top end of the guide plate 10. Specifically, the hinge position between the lever 14 and the guide plate 10 is at the guide plate 10. 0 side of the central axis, so that when the lever 14 is squeezed and moves toward the side of the guide plate 10, the guide plate 10 will deflect at a certain angle with the fixed shaft 9 as the rotation axis due to the eccentric squeezing. Further, a circular groove with a diameter larger than the outer diameter of the spiral spring 15 is provided on the outer wall of the end of the guide plate 10, and the other end of the spiral spring 15 is fixedly connected to the bottom inner surface of the circular groove.

[0035] In addition, in order to enhance the spoiler effect of the guide plate 10 when it moves in the hair dryer 4, a flip assembly is arranged inside the guide plate 10, and the flip assembly includes a magnetic slide bar 16, and the magnetic slide bar 16 is slidably installed on the inner wall of the guide plate 10, and a straight slot 17 is provided on the inner wall of the magnetic slide bar 16, and the inner wall of the guide plate 10 is rotatably connected to the top end of the rotating shaft 18, and the bottom end of the rotating shaft 18 is fixedly connected to the spoiler 19, and the upper surface of the spoiler 19 is rotatably connected to the bottom end of the coupling 20, and the top end of the coupling 20 is fixedly connected to the lower surface of the magnetic slide bar 16.

[0036] In an embodiment of the present invention, a magnetic plate is provided at the end of the accommodating groove, and the number of the magnetic plates is set to two groups, and the two groups of magnetic plates are respectively arranged on the left and right sides of the alignment position of the magnetic slide bar 16, and the magnetic plate and the magnetic slide bar 16 have the same magnetism, so that when the guide plate 10 is deflected with the fixed shaft 9 as the rotation center, due to the repulsive force between the magnetic plate and the magnetic slide bar 16, the magnetic slide bar 16 slides on the inner wall of the guide plate 10, and at the same time, the rotating shaft 18 is arranged inside the straight slot 17, so that the magnetic slide bar 16 will not interfere with the normal rotation of the rotating shaft 18 when it moves in the guide plate 10, and further, the coupling 20 is arranged on the side of the central axis of the magnetic slide bar 16, so that the magnetic slide bar 1 When sliding along the inner wall of the guide plate 10, the coupling 20 can be used to drive the spoiler 19 to deflect, thereby changing the contact area between the guide plate 10 and the airflow and the shape of the contact surface, so that it can better disturb the airflow, improve the swirl effect of the hot air blown out by the hair dryer 4, and thus improve the processing effect on the galvanized pipe. In addition, the number of spoilers 19 is set in multiple groups, and the multiple groups of spoilers 19 are evenly arranged on the inner wall of the guide plate 10 in a linear array. Specifically, the couplings 20 between two adjacent groups of spoilers 19 are respectively arranged on different side surfaces of the central axis of the magnetic slide bar 16, so that the two adjacent groups of spoilers 19 change the airflow in different directions, further improving the spoiler effect of the guide plate 10.

At this time, the hot air blower 3 is started so that the hot air blower 3 continuously generates hot air and blows it out through the blower 4, so that the excess zinc layer in the galvanized pipe on the feeding mechanism 2 is blown out, ensuring that the thickness of the zinc layer in the galvanized pipe is consistent, and improving the processing effect of the galvanized pipe. At the same time, in order to avoid the effect of the blower 4 blowing out hot air with a certain stroke affecting the consistency of the zinc layer at different positions in the galvanized pipe, a swirl mechanism is set, and the pinion 7 and the gear ring 8 are matched, so that the multiple groups of guide plates 10 in the blower 4 can divide the airflow blown into the blower 4 and apply a force of circular movement, so that the hot air blown out by the blower 4 is blown into the galvanized pipe in a rotating manner, thereby improving the blowing effect of the excess zinc layer in the galvanized pipe, and further improving the processing effect of the galvanized pipe. In addition, in order to further improve the effect of the guide plate 10 on the change of wind direction, a toggle mechanism is set , cooperate with the driving gear 12 and the driven gear 13, so that the toggle wheel 11 and the hair dryer 4 rotate relatively irregularly, and then cooperate with the toggle wheel 11 to push and squeeze the toggle rod 14, so that when the toggle rod 14 is squeezed and moves toward the side of the guide plate 10, due to the eccentric squeezing, the guide plate 10 will deflect at a certain angle with the fixed axis 9 as the rotation axis, thereby affecting the airflow direction in the hair dryer 4 and achieving a better spoiler effect. At the same time, in order to improve the spoiler effect of the guide plate 10 when it moves in the hair dryer 4, a flip assembly is provided, and the magnetic plate and the magnetic slide bar 16 are provided in the accommodating groove, so that when the guide plate 10 is flipped, the magnetic slide bar 16 slides along the inner wall of the guide plate 10 and cooperates with the coupling 20 to drive the spoiler 19 to deflect, thereby changing the contact area between the guide plate 10 and the airflow and the shape of the contact surface, so that it can better spoil the airflow, improve the swirl effect of the hot air blown out by the hair dryer 4, and then improve the processing effect on the galvanized pipe.
