Description

Technical Field

[0001] The present invention relates to the field of galvanized steel pipe production equipment, in particular to a galvanized steel pipe production equipment for controlling the zinc coating amount and its usage method. Background Art

[0002] When producing galvanized steel pipes, galvanizing of the galvanized steel pipes is required to prevent rusting and rotting of the galvanized steel pipes. During galvanizing, common methods are hot-dip galvanizing and cold-dip galvanizing (also known as electro-galvanizing). Since hot-dip galvanizing can galvanize multiple steel pipes at one time, it is more widely used. During operation, the steel pipes are sent into the hot-dip galvanizing bath through a feeding iron chain, and the galvanizing process can be automatically completed.

[0003] When galvanizing by hot-dip galvanizing, a common device is a hot-dip galvanizing bath, which can automatically control the temperature of the hot-dip galvanizing bath through a program and sensors, thereby changing the zinc coating amount on the side wall of the galvanized steel pipe (when the temperature is lower than 430°C, the fluidity of the zinc liquid becomes poor, the zinc-iron diffusion rate decreases, and it is difficult to form a sufficient iron-zinc alloy layer, resulting in a thinner coating quality; when it exceeds 530°C, the iron-zinc diffusion rate accelerates, and the alloying layer is rapidly formed, resulting in an overly thick coating), and then the zinc coating amount is controlled.

[0004] However, when the existing hot-dip galvanizing bath is in use, if the surface of the steel pipe is not thoroughly cleaned or intermetallic compounds formed by iron and zinc or aluminum, zinc slag will float on the liquid surface of the hot-dip galvanizing bath. At this time, in order to prevent the zinc slag from being carried out when the galvanized steel pipe is removed, workers need to use an iron rake to scrape the zinc slag on the surface of the hot-dip galvanizing bath to both ends. Since pungent odors are generated during galvanizing, it will affect the health of workers. Moreover, due to the high temperature during galvanizing, workers will feel uncomfortable when approaching the galvanizing bath (especially in summer). Therefore, it has become a social need to design a galvanizing device that can automatically scrape the zinc slag and can automatically avoid the feeding iron chain. Summary of the Invention

[0005] In view of the problem that in the above-mentioned or existing technology, workers use an iron rake to scrape the zinc slag on the surface of the hot-dip galvanizing bath to both ends, pungent odors are generated during galvanizing, which affect the health of workers, and the temperature is high during galvanizing, and workers will feel uncomfortable due to the high temperature when approaching the galvanizing bath, and there is a lack of a galvanizing device that can automatically scrape the zinc slag and can automatically avoid the feeding iron chain, the present invention is proposed.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example 1, reference Figures 1 to 5 , which is the first embodiment of the present invention, and provides a galvanized steel pipe production equipment for controlling the amount of zinc applied, which can automatically remove the upper zinc slag in the hot-dip galvanizing pool 10, and comprises a galvanizing component, including a hot-dip galvanizing pool 10, a wireless transmitter 11 is arranged on the side wall of the hot-dip galvanizing pool 10, a heating plate is arranged on the bottom and side wall of the hot-dip galvanizing pool 10, and a feeding chain 12 is arranged on the hot-dip galvanizing pool 10; a cleaning component, including a mounting plate 20 arranged on the side wall of the hot-dip galvanizing pool 10, and a There is a mounting frame 21, a power part 22 is provided on the mounting plate 20 to provide power for the mounting frame 21 to slide left and right, the mounting frame 21 is connected to an L-shaped plate 24 through an elastic part 23, a scraping part 25 for cleaning the hot-dip galvanizing pool 10 is provided on the L-shaped plate 24, and a one-way part 26 is provided on the mounting plate 20 to ensure the one-way scraping of the scraping part 25; the avoidance component includes a rotating part 30 arranged on the L-shaped plate 24, and a positioning part 31 and a toggle part 32 for providing power for the rotating part 30 are provided on the mounting plate 20.

[0034] Specifically, the wireless transmitter 11 can transmit the temperature inside the hot-dip galvanizing bath 10 to an external control center and can receive external control signals, thereby opening or closing the heating plate to control the temperature rise and fall of the hot-dip galvanizing bath 10 to achieve the control of the zinc coating amount (when the temperature is lower than 430 °C, the fluidity of the zinc liquid becomes poor, the zinc-iron diffusion rate decreases, and it is difficult to form a sufficient iron-zinc alloy layer, resulting in a thinner coating quality; when it exceeds 530 °C, the iron-zinc diffusion rate accelerates, and the alloying layer is rapidly formed, resulting in an overly thick coating). Here, a hoist is provided at the outer end of the feeding iron chain 12 for feeding galvanized steel pipes. The above is the prior art and will not be elaborated here. Here, one steel pipe can be galvanized at a time, or multiple steel pipes can be placed at once through a bracket, which is not limited here.

[0035] Further, the power unit 22 includes two electric slide rails 221 provided on the mounting plate 20. Sliders 222 fixed to the mounting frame 21 are slidably connected within the two electric slide rails 221; the elastic unit 23 includes a lifting block 231 slidably connected to the inner wall of the mounting frame 21. The lifting block 231 is elastically connected to the inner wall of the mounting frame 21 through a first spring 232. A guide rod 233 fixed to the L-shaped plate 24 is fixedly connected to the lifting block 231; the scraping unit 25 includes a cross bar 251 provided on the L-shaped plate 24. A bearing groove 252 is provided on the cross bar 251. An L-shaped iron rake 253 is slidably connected within the bearing groove 252. The right side wall of the left end iron rake 253 is flush with the right side wall of the cross bar 251. The iron rake 253 is elastically connected to the inner wall of the mounting groove 265 through a second spring 254. An inclined surface 255 is provided on the iron rake 253.

[0036] Among them, here the two sliders 222 move towards the middle or towards both ends simultaneously. In the initial position, there is a gap between the iron rake 253 and the liquid surface of the galvanizing bath. The right side wall of the left end iron rake 253 is flush with the right side wall of the cross bar 251 (similarly for the right end), so that when the two iron rakes 253 abut against each other, there is no gap in the middle, and the setting of the inclined surface 255 makes the zinc slag scraping effect better.

[0037] Preferably, the one-way unit 26 includes a first transverse groove 261 provided on the mounting plate 20. A vertical groove 262 is communicated with the first transverse groove 261. A second transverse groove 263 parallel to the first transverse groove 261 is communicated with the vertical groove 262. The second transverse groove 263 is communicated with the first transverse groove 261 through a first inclined groove 264. The guide rod 233 cooperates with the first transverse groove 261, the vertical groove 262, the second transverse groove 263, and the first inclined groove 264; an installation groove 265 is provided on the first transverse groove 261. A wedge block 266 with an inclined surface 255 facing downwards is slidably connected within the installation groove 265. The wedge block 266 is elastically connected to the inner wall of the installation groove 265 through a third spring 267.

[0038] It should be noted that the first horizontal groove 261 is located above the second horizontal groove 263, and the inclined surface 255 of the wedge block 266 faces downward, so that when the guide rod 233 moves upward, it will not be restricted. When the guide rod 233 enters the first horizontal groove 261, the guide rod 233 cannot move past the wedge block 266 into the first inclined groove 264.

[0039] During use, in the initial state, the iron rakes 253 are at both ends of the hot-dip galvanizing bath 10 and do not extend into the processing area (mainly between the two feeding iron chains 12, because the feeding iron chains 12 are at both ends of the galvanized steel pipe, the same below), and will not affect the lifting of the feeding iron chains 12. After galvanizing is completed, the feeding iron chains 12 move the galvanized steel pipe out. At this time, the two electric slide rails 221 are activated, causing the two sliders 222 to move towards the middle, and thus the two mounting frames 21 move towards the middle. The lifting block 231 moves towards the middle, driving the guide rod 233 to move, and the L-shaped plate 24 moves, causing the iron rakes 253 to move towards the middle. It should be noted that at this time, there is a gap between the iron rakes 253 and the liquid level of the hot-dip galvanizing bath 10, and the welding slag on the galvanizing bath will not be pushed to the middle of the hot-dip galvanizing bath 10.

[0040] When the iron rakes 253 move towards the middle, the guide rod 233 slides in the first horizontal groove 261 for guiding. At this time, the first spring 232 is in an extended state. When the side walls of the two iron rakes 253 abut against each other, the iron rakes 253 reach the middle position of the hot-dip galvanizing bath 10, and the guide rod 233 is aligned with the vertical groove 262. Under the action of the first spring 232, the slider 222 resets downward, and the guide rod 233 moves downward to drive the L-shaped plate 24 to move, causing the lower ends of the iron rakes 253 to extend below the liquid level of the hot-dip galvanizing bath 10 (it should be noted that it will not extend too far below the liquid level to avoid the phenomenon of pushing the liquid in the hot-dip galvanizing bath 10 out from the edge when stirring). Then the electric slide rail 221 is activated, causing the slider 222 to move towards both ends. At this time, the two iron rakes 253 are driven to move towards both ends through transmission, pushing the zinc slag in the processing area to both ends of the hot-dip galvanizing bath 10, realizing the automatic cleaning of the zinc slag.

[0041] When the iron rake 253 moves towards both ends, the guide rod 233 slides in the second horizontal groove 263. When the iron rake 253 is about to approach the edge of the hot-dip galvanizing bath 10, the guide rod 233 moves to the connection of the second horizontal groove 263 and the first inclined groove 264. At this time, when the slider 222 continues to move, it will drive the guide rod 233 to move in the first inclined groove 264. At this time, when the iron rake 253 moves at the edge, it will move upward again. Thus, when the iron rake 253 moves towards the middle next time, it will not bring zinc slag to the middle, ensuring the one-way scraping of waste materials by the iron rake 253. When the guide rod 233 abuts against the wedge block 266, since the inclined surface 255 of the wedge block 266 faces downward at this time, when the guide rod 233 moves from the first inclined groove 264 to the first horizontal groove 261, the wedge block 266 moves towards the installation groove 265, and the third spring 267 is compressed, which will not block the guide rod 233. When the guide rod 233 moves into the first horizontal groove 261, since the non-inclined surface 255 of the wedge block 266 abuts against the guide rod 233, the guide rod 233 cannot directly reset from the first horizontal groove 261 to the first inclined groove 264, ensuring the one-way movement of the guide rod 233.

[0042] In summary, by setting up the cleaning component, when the electric slide rail 221 starts to drive the slider 222 to move, it can drive the iron rake 253 to move through transmission, automatically collect zinc slag, and by setting up the one-way part 26, it can make the iron rake 253 scrape waste materials only from the middle towards both ends, ensuring the waste scraping effect and making the zinc slag collection effect better.

[0043] Embodiment 2, referring to Figures 1 to 8 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an avoidance component for the galvanized steel pipe production equipment that controls the zinc feeding amount, solving the problem of how to avoid zinc slag treatment in the hot-dip galvanizing bath 10 during galvanizing. It includes a rotating part 30, which includes an inner groove 301 arranged on the L-shaped plate 24. A rotating shaft is rotatably connected in the inner groove 301. A torsion spring 302 is arranged on the rotating shaft. A connecting block 303 fixed to the cross bar 251 is fixedly connected to the rotating shaft. The bottom of the connecting block 303 abuts against the inner wall of the inner groove 301. A circular opening is arranged on the inner wall of the inner groove 301. The rotating shaft passes through the circular opening and is fixedly connected to a gear 304. A sliding sleeve 305 is fixedly connected to the L-shaped plate 24. A rack 306 meshing with the gear 304 is slidably connected in the sliding sleeve 305. A lever 307 is fixedly connected to the rack 306. The positioning part 31 includes a plurality of threaded holes 311 arranged on the mounting plate 20. There is a spray code outside the plurality of threaded holes 311. A screw rod 312 is threadedly connected in one of the threaded holes 311. A guide plate 313 is fixedly connected to the screw rod 312. The height of the guide plate 313 is greater than the displacement of the L-shaped plate 24 when it descends.

[0044] Specifically, when galvanizing steel pipes, it is inevitable that there will be a lot of zinc slag during the galvanizing process. At this time, in order to avoid bringing out welding slag during the removal of the steel pipe, the welding slag needs to be cleaned. When the horizontal bar 251 rotates, it can change from horizontal to vertical, so as to avoid being stuck with the feeding chain 12 when moving left and right. The second spring 254 is set here, so that the iron rake 253 can be retracted into the installation groove 265, so as to avoid the iron rake 253 and the hot-dip galvanizing pool 10 from being stuck to each other when the horizontal bar 251 is deflected.

[0045] Furthermore, the toggle portion 32 includes two third transverse grooves 321 arranged on the guide plate 313, and a fourth transverse groove 322 is provided at the rear ends of the two third transverse grooves 321. The two third transverse grooves 321 have different lengths, and the two third transverse grooves 321 are connected to the fourth transverse groove 322 through the second inclined groove 323. An outward expansion groove 324 is provided in the second inclined groove 323, and a transmission shaft 325 is rotatably connected in the outward expansion groove 324. A stopper 326 extending to the connection between the two second inclined grooves 323 is fixedly connected to the transmission shaft 325, and a return spring is provided on the transmission shaft 325.

[0046] It should be noted that the height of the guide plate 313 is greater than the downward displacement of the L-shaped plate 24, so that no matter whether the L-shaped plate 24 rises or falls, the lever 307 can cooperate with the third transverse groove 321. The depth of the third transverse groove 321 and the second inclined groove 323 are both less than the height of the guide plate 313, and the front end side wall of the stop block 326 is in contact with the outward expansion groove 324.

[0047] When in use, first determine the distance between the two steel cables according to the length of the steel pipe, then find the required threaded hole 311 according to the inkjet code, the inkjet code here corresponds to galvanized steel pipes of different lengths, directly turn the screw 312 into the threaded hole 311 according to the inkjet code, and then let the third transverse groove 321 face upwards, the number of thread turns can be set here to ensure that the third transverse groove 321 faces upwards after tightening, and at the same time, there is damping between the screw 312 and the threaded hole 311 here to ensure that the screw 312 does not rotate by itself;

[0048] During the movement of the left L-shaped plate 24 toward the middle, the lever 307 first cooperates with the third transverse groove 321. At this time, there is a gap between the iron rake 253 and the left feeding chain 12. Then the lever 307 cooperates with the second inclined groove 323, so that the lever 307 moves backward, and at this time, the tooth plate 306 moves backward, so that the gear 304 rotates, thereby rotating the shaft, and the torsion spring 302 obtains elasticity, so that the connecting block 303 rotates, and the horizontal bar 251 changes from horizontal to vertical, and then the lever 307 moves to the third transverse groove 321. In the fourth transverse groove 322, the horizontal bar 251 does not reset, so it will not collide with the feeding iron chain 12. When the horizontal bar 251 passes over the left feeding iron chain 12, the lever 307 is separated from the guide plate 313. Under the action of the torsion spring 302, the horizontal bar 251 resets. When the left end horizontal bar 251 moves to the left, the front side wall of the stopper 326 abuts against the outer expansion groove 324, so that when the lever 307 is in the fourth transverse groove 322, it will not directly move from the fourth transverse groove 322 to the second inclined groove 323.

[0049] It is worth noting that since the right side wall of the left end iron rake 253 is flush with the right side wall of the horizontal bar 251, when the lever 307 moves toward the middle, the lengths of the two pairs of third horizontal grooves 321 are different, which can ensure that the iron rake 253 and the feeding chain 12 do not get stuck.

[0050] In summary, by setting up the avoidance component, during the galvanizing process, when there is a lot of zinc slag, the zinc slag can also be cleaned, and the iron rake 253 and the feeding chain 12 can be automatically prevented from getting stuck, which makes it more flexible to use and avoids the zinc slag being brought out by the side wall when the galvanized steel pipe is moved out.

[0051] Embodiment 3, referring to FIG. 5 to FIG. 6 , is a third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a method for using a galvanized steel pipe production device for controlling the amount of zinc applied, which includes:

[0052] S1: Send a signal to the wireless transmitter 11 to start the heating plate to heat the liquid in the hot-dip galvanizing pool 10 to 450°C;

[0053] S2: The galvanized steel pipe is fed into the hot-dip galvanizing pool 10 through the feeding chain 12, and the liquid in the hot-dip galvanizing pool 10 is completely submerged in the galvanized steel pipe;

[0054] S3: directly observing the amount of zinc slag on the surface of the hot-dip galvanizing pool 10 from a distance, and judging whether zinc slag treatment is required;
