Description

Technical Field

[0001] This utility model relates to the field of galvanizing pot equipment, and more specifically, to a zinc pot for precise material addition in galvanizing. Background Technology

[0002] During the production and processing of steel profiles, a layer of zinc is often plated on the surface of the steel profiles for aesthetic purposes and rust prevention. Hot-dip galvanizing involves first pickling the steel parts to remove iron oxide from the surface. After pickling, the parts are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. Then, the steel profiles are hoisted and sent into the galvanizing pot for galvanizing.

[0003] However, in the use of existing galvanizing pots, the composition and level stability of the zinc liquid directly affect the adhesion of the zinc layer, the amount of zinc dross generated, and the quality of the final product. Currently, zinc pots are mostly filled manually in batches with zinc ingot alloying agents, resulting in large fluctuations in the zinc liquid composition, making it difficult to precisely maintain within the process requirements, thus affecting the adhesion of the zinc layer. Furthermore, this method cannot match the continuous production rhythm of the galvanizing unit, making precise replenishment difficult and hindering the quality control of extremely thin zinc layers. Therefore, it has certain limitations in practical use. In view of this, we propose a galvanizing pot with precise replenishment to solve the above problems. Utility Model Content

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] Example 1

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A zinc plating pot for precise feeding includes a galvanizing pot body 1. A mounting frame 2 is fixedly connected to the upper surface of the galvanizing pot body 1. Two storage bins 3 are fixedly fitted inside the mounting frame 2. The two storage bins 3 have identical structures. The left storage bin 3 is the main storage bin (for storing zinc ingots), and the right storage bin 3 is the auxiliary storage bin (for storing aluminum alloying agent), thus avoiding material mixing and providing a stable feed source for quantitative feeding. Since the two storage bins 3 have identical structures, the following description focuses on one storage bin 3. A solenoid valve 4 is installed at the outlet of the storage bin 3. The solenoid valve 4 is electrically connected to an external control unit. A connecting pipe 5 is fixedly connected to the outlet of the storage bin 3. The internal part of the 5 is equipped with a buffer component, and the internal part of the storage bin 3 is equipped with a partition plate 6. The surface of the partition plate 6 has an opening for material to pass through. A vertical rod 7 is fixedly connected to the upper surface of the partition plate 6. A first fixing rod 8 is slidably sleeved on the outside of the vertical rod 7. The upper end face of the first fixing rod 8 is fixedly connected to the top wall of the storage bin 3. A threaded rod 9 is rotatably connected inside the first fixing rod 8. The vertical rod 7 is threadedly sleeved on the outside of the threaded rod 9. A transmission rod 10 is fixedly connected to the upper end of the threaded rod 9. The transmission rod 10 rotates through the first fixing rod 8 and the upper surface of the storage bin 3 in sequence. An adjustment component is provided on the outside of the upper end of the transmission rod 10. A shielding component is provided on the surface of the partition plate 6.

[0032] In the above embodiments, a liquid level detection module (such as a float-type liquid level sensor) and a component detection module (such as an online zinc liquid component analyzer) can be installed on the inner wall of the galvanizing pot body 1 to collect zinc liquid level and Al / Fe element content data in real time and transmit them to the control unit.

[0033] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the adjustment assembly includes a worm gear 17, which is fixedly sleeved on the outside of the transmission rod 10. A worm 18 is meshed with the outside of the worm gear 17. A first motor 19 is fixedly connected to the upper surface of the storage bin 3. The output shaft of the first motor 19 is fixedly connected to the worm 18 via a coupling. By starting the first motor 19 through the external control assembly, the transmission rod 10 can be driven to rotate. The rotation of the transmission rod 10 can drive the threaded rod 9 to rotate. The rotation of the threaded rod 9 can drive the vertical rod 7 to slide inside the first fixed rod 8, thereby realizing the movement of the partition plate 6 inside the storage bin 3, thereby realizing the adjustment of the volume of the lower chamber of the partition plate 6, and ultimately realizing the adjustment of the single feeding amount.

[0034] In the above embodiments, the worm gear 17, worm 18 and the first motor 19 are also provided with protective covers. The protective covers are fixedly connected to the upper surface of the storage bin 3, and the protective covers are provided to protect the internal structure.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the surface of the storage bin 3 is provided with an observation window 21, and the surface of the observation window 21 is provided with scale markings. The observation window 21 makes it easy for staff to see the position of the internal partition 6, thereby effectively controlling the internal volume.

[0036] Example 2

[0037] The zinc pot for galvanizing with precise material addition provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the shielding assembly includes a rotating rod 11, which is rotatably connected to the upper surface of the partition plate 6. The lower end of the rotating rod 11 rotates through the lower surface of the partition plate 6. A sealing plate 12 is fixedly connected to the lower end of the rotating rod 11. The upper surface of the sealing plate 12 is in contact with the lower surface of the partition plate 6. The rotation of the rotating rod 11 can drive the rotation of the sealing plate 12, so that the sealing plate 12 will no longer block the opening of the partition plate 6. The material located on the upper side of the partition plate 6 will enter the lower side of the partition plate 6 through the opening. The purpose of quantitative feeding can be achieved by using the solenoid valve 4 set at the discharge port of the storage bin 3.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a second fixed rod 13 is rotatably connected to the top wall of the storage bin 3. A rotating rod 11 is slidably sleeved inside the second fixed rod 13. A synchronization groove 14 is provided on the inner wall of the second fixed rod 13. A synchronization block 15 is fixedly connected to the outside of the rotating rod 11. The synchronization block 15 is slidably connected inside the synchronization groove 14. When the second fixed rod 13 rotates, the rotating rod 11 can be driven to rotate by the cooperation of the synchronization block 15 and the synchronization groove 14. When the partition plate 6 moves, it will drive the rotating rod 11 to move. At this time, the rotating rod 11 will slide inside the second fixed rod 13.

[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a second motor 20 is fixedly connected to the upper surface of the storage bin 3. The output shaft of the second motor 20 rotates through the interior of the storage bin 3 and is fixedly connected to the second fixed rod 13 through a coupling. The second motor 20 can be started by an external control component to drive the rotation of the second fixed rod 13.

[0040] Among them, the first motor 19 and the second motor 20 are also equipped with power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.

[0041] In the above embodiments, in order to ensure the stability of the operation of the second motor 20, a protective cover can also be provided on the outside of the second motor 20. Since this is a conventional technical means in the field, it will not be described in detail here.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the buffer assembly includes several baffles 22. The baffles 22 are fixedly connected to the inner wall of the connecting pipe 5. A rotating plate 23 is provided on the lower side of the baffles 22. The rotating plate 23 is rotatably disposed in a groove opened on the lower surface of the baffles 22. At this time, the baffles 22 can limit the angle of the rotating plate 23 and effectively prevent materials from getting stuck in the gap. The rotating plate 23 is rotatably connected to the inside of the connecting pipe 5 through a shaft.

[0043] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, cavities 24 are provided inside the vertical plates on both sides of the connecting pipe 5. The shaft of the rotating plate 23 rotates through the cavity 24. A circular plate 25 is fixedly connected to one end of the shaft of the rotating plate 23 inside the cavity 24. A torsion spring 16 is fixedly connected between the circular plate 25 and the inner wall of the cavity 24. The torsion spring 16 is movably sleeved outside the shaft of the rotating plate 23. When the material inside the storage bin 3 falls into the interior of the connecting pipe 5, the material will first contact the rotating plate 23, thereby forcing the rotating plate 23 to rotate under the baffle plate 22. At this time, the torsion spring 16 will generate elastic deformation, thereby buffering the falling material and reducing the falling speed of the material, ultimately reducing the disturbance of the zinc liquid.

[0044] In the above embodiments, the interior of the connecting pipe 5, the surface of the baffle plate 22, and the surface of the rotating plate 23 can all be provided with an anti-stick coating (such as a silicon nitride coating) to prevent materials from sticking to the wall and ensure smooth feeding.

[0045] The process of using the precision-filling zinc pot for galvanizing provided by this utility model is as follows:

[0046] The volume inside the two storage bins 3 is adjusted by adding the main material and auxiliary material respectively. The first motor 19 is started by the external control component, which drives the transmission rod 10 to rotate. The rotation of the transmission rod 10 drives the threaded rod 9 to rotate. The rotation of the threaded rod 9 drives the vertical rod 7 to slide inside the first fixed rod 8, thereby realizing the movement of the partition plate 6 inside the storage bin 3, thereby realizing the adjustment of the volume of the lower chamber of the partition plate 6.

[0047] After the volume of the two storage bins 3 is adjusted, the staff will add the material to be added to the two storage bins 3 respectively. At this time, the material will be located on the upper side of the partition plate 6, and the material will not enter the lower chamber of the partition plate 6 under the action of the sealing plate 12. The staff can start the second motor 20 through the external control component to drive the rotation of the second fixed rod 13. When the second fixed rod 13 rotates, the rotating rod 11 can be driven to rotate with the help of the synchronization block 15 and the synchronization groove 14, so that the material enters the lower chamber of the partition plate 6. After the lower chamber is filled, the second motor 20 is started again through the external control component to make the sealing plate 12 block the partition plate 6.

[0048] Subsequently, if the liquid level detection module detects that the zinc liquid level is lower than the threshold, or if the composition detection module detects that the Al element content is lower than the threshold, the external control component will activate the solenoid valve 4 located on the lower side of the storage bin 3 according to the instruction type, thereby adding a certain amount of material into the interior of the lower galvanizing pot body 1. After the addition is completed, the solenoid valve 4 will close.

[0049] Once a single addition is completed, the external control component will restart the second motor 20, thereby allowing the material to enter the lower side of the partition plate 6, awaiting subsequent material addition.
