Description

Technical Field

[0001] This utility model relates to the field of galvanizing tank technology, and in particular to a galvanizing tank impurity removal mechanism. Background Technology

[0002] Hot-dip galvanizing is a common surface coating anti-corrosion measure in the metal processing industry. For example, when galvanizing steel strips, they are transported through a zinc bath for galvanizing. Immersing the steel strip in the zinc bath isolates its surface from air, preventing oxidation. During galvanizing, the surface of the zinc bath produces oxides and a large amount of dross due to the contact between the zinc and air. If this dross is not removed promptly, it accumulates and adheres to the steel strip's surface when it is removed from the zinc bath, affecting the galvanizing quality. Therefore, cleaning the galvanizing bath is crucial for ensuring the quality of galvanized metal products. Currently, galvanizing baths / tanks typically use nets to remove dross from the zinc bath. However, these nets become clogged with dross after a period of use, requiring frequent replacement or cleaning. This cleaning method is inefficient and costly to maintain, and due to the high temperature of the zinc bath, it also poses safety hazards. Utility Model Content

[0003] In view of the above, it is necessary for this utility model to provide a convenient and safe impurity removal mechanism for galvanizing tanks.

[0004] The technical solution of this utility model is as follows:

[0005] A galvanizing bath impurity removal mechanism includes a zinc bath, a collection mechanism, and a dispensing mechanism. The collection mechanism includes a mounting frame, a power motor, a rotating shaft, a paddle wheel, and a self-cleaning unit. The mounting frame is fixed to the side wall of the zinc bath, with its top end extending beyond the surface of the molten zinc. The power motor is fixed to the top of the mounting frame, with its output end extending downwards. The rotating shaft is connected to the output end of the power motor, with its lower end extending below the mounting frame. The paddle wheel is fixedly mounted at the end of the rotating shaft. The self-cleaning unit includes a scraper, which is vertically and flexibly mounted on the rotating shaft. The rotation of the rotating shaft drives the scraper to rise and fall. The dispensing mechanism is installed on the top surface of the zinc bath and located beside the collection mechanism. The dispensing mechanism has a collection block that is suspended in the zinc bath and positioned in the direction of the zinc bath's flow, allowing the molten zinc to carry zinc dross to adhere to the collection block.

[0006] Furthermore, a spiral slide is provided on the outer circumferential surface of the rotating shaft, and a sliding hole is provided at the center of the scraper. The inner wall of the sliding hole is provided with ball bearings that cooperate with the spiral slide to drive the scraper to rise and fall along the rotating shaft when the rotating shaft rotates.

[0007] Furthermore, the top surface of the scraper is designed as a smooth spherical arc surface.

[0008] Furthermore, a fan impeller is fixedly sleeved on the upper end of the rotating shaft to scrape off the scum adhering to the top surface of the scraper.

[0009] Furthermore, a scraper is fixedly sleeved at the lower end of the rotating shaft to scrape off the scum adhering to the bottom surface of the scraper.

[0010] Furthermore, the mounting frame includes a base plate, a support rod, and a top plate. The base plate is horizontally positioned inside the zinc bath and one end is fixedly connected to the side wall of the zinc bath. The support rod is erected on the base plate, and the top plate is installed on top of the support rod for mounting a power motor.

[0011] Furthermore, the collection mechanism includes a stand and an electric hoist. The stand is fixed to the top surface of the side wall of the zinc pool, and the electric hoist is installed at the top of the stand to lift the collection block into the zinc pool for suspension.

[0012] Furthermore, the trapping block has a rough surface and is an irregularly shaped block.

[0013] Furthermore, the zinc bath has an arc-shaped bottom surface, and the two ends of the arc-shaped bottom surface form a height difference, with the converging mechanism located at the lower end of the arc-shaped bottom surface in the zinc bath.

[0014] Compared with the prior art, the zinc plating tank impurity removal mechanism provided by this utility model makes the bottom surface of the zinc tank sloped, so that the zinc dross is more concentrated and easier to collect when it settles. It also sets a paddle wheel to drive the zinc liquid to flow in the same direction, which is conducive to collecting the zinc dross flowing with the zinc liquid. By setting a suspended collecting block in the direction of zinc liquid flow, the zinc dross flowing with the zinc liquid is adsorbed, which greatly improves the impurity removal efficiency of zinc liquid.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-3 A galvanizing bath impurity removal mechanism includes a zinc bath 1, a gathering mechanism 2, and a collecting mechanism 3. The zinc bath 1 has an arc-shaped bottom surface with a height difference between its two ends. The gathering mechanism 2 is located at the lower end of the arc-shaped bottom surface in the zinc bath 1. The collecting mechanism 3 is installed on the top surface of the zinc bath 1 and is located next to the gathering mechanism 2. The zinc liquid is driven to flow to the collecting mechanism 3 through the gathering mechanism 2 so that the collecting mechanism 3 can adsorb and remove the scum in the zinc liquid.

[0022] The converging mechanism 2 includes a mounting frame 21 and a power motor 22. The mounting frame 21 is erected inside the zinc bath 1, with its lower end fixed to the side wall inside the zinc bath 1 and its top end extending outside the zinc bath 1. The power motor 22 is located at the top of the mounting frame 21 and is driven to rotate by hydraulic or pneumatic power. The rotating end of the power motor 22 is inserted downward into the mounting frame 21, and a rotating shaft 23 is located below the rotating end, corresponding to and coinciding with the shaft of the power motor 22. The power motor 22 and the rotating shaft 23 are connected by a coupling, so that the power motor 22 drives the rotating shaft 23 to rotate. Specifically, the rotating shaft 23 extends downward outside the mounting frame 21, and a slurry wheel 24 for driving the flow of zinc liquid is installed at its end. The rotation of the rotating shaft 23 drives the slurry wheel 24 to rotate synchronously.

[0023] Furthermore, the mounting frame 21 includes a base plate 211, several support rods 212, a top plate 213, and guide columns 214. The base plate 211 is horizontally positioned within the zinc bath 1 and one end is fixedly connected to the side wall of the zinc bath 1. The support rods 212 are respectively erected on the base plate 211 on adjacent opposite sides. The base plate 211 has shaft holes that mate with the rotating shaft 23, allowing the rotating shaft 23 to be inserted into the shaft holes for rotation. The top plate 213 is adjustablely mounted on the top of the support rods 212 by bolts. Understandably, the top of the support rods 212 has a threaded section for mate with the bolts. A through hole is provided on the top plate 213 at a position coaxial with the shaft hole of the base plate 211, so that after the power motor 22 is fixed on the top plate 213, its rotating end passes through the through hole to drive the rotating shaft 23 to rotate coaxially. The guide columns 214 are erected on the base plate 211 and pass through the top plate 213, which can improve the stability of the mounting frame 21.

[0024] Understandably, the lower half of the mounting bracket 21 is immersed in the molten zinc, and the lower ends of the support rod 212, guide post 214 and rotating shaft 23 are also immersed in the molten zinc. When scum forms on the surface of the molten zinc, it is easy to adhere to the support rod 212, guide post 214 and rotating shaft 23.

[0025] The collection mechanism 2 further includes a self-cleaning unit 25 for cleaning scum.

[0026] The self-cleaning unit 25 includes a scraper 251, which is movably mounted on a support rod 212. Specifically, the scraper 251 has several sliding holes on its surface. The inner wall of the sliding hole located at the center of the scraper 251 is provided with a ball bearing. The outer circumference of the rotating shaft 23 is provided with a spiral slide 231 that cooperates with the ball bearing. When the rotating shaft 23 rotates, it drives the scraper 251 to rise and fall. The top surface of the scraper 251 is a smooth spherical surface, so that when the scraper 251 rises above the surface of the zinc liquid, the scum adhering to the scraper 251 can slide off along the spherical surface.

[0027] Furthermore, the self-cleaning unit 25 includes a fan impeller 252, which is sleeved on the top of the rotating shaft 23 and located above the scraper 251. The rotating shaft 23 drives the fan impeller 252 to rotate. When the top surface of the scraper 251 rises to near the fan impeller 252, the fan impeller 252 can scrape off the floating scum on the scraper 251.

[0028] Furthermore, the self-cleaning unit 25 includes a scraper 253, which is fixedly sleeved on the rotating shaft 23 and located on the top surface of the base plate 211. When the scraper plate 251 descends to the lowest point, it contacts the scraper plate 253. The scraper plate rotates with the rotating shaft 23, scraping off the slag attached to the bottom surface of the scraper plate 251 and pushing the zinc liquid to flow, thus driving the zinc slag to flow to the collection mechanism 3.

[0029] Furthermore, the surfaces of the rotating shaft 23, guide column 214 and scraper 251 are coated with a ceramic film, making it difficult for scum to adhere to the surface.

[0030] The collection mechanism 3 includes a frame 31, an electric hoist 32, and a collection block 33. The frame 31 is fixedly erected on the top surface of the side wall of the zinc pool 1 and close to the collection mechanism 2. The electric hoist 32 is fixed on the frame 31 and corresponds to the top of the zinc pool 1. The collection block 33 is suspended below the electric hoist 32. The electric hoist 32 lifts the collection block 33 and puts it into the zinc pool 1, and suspends the collection block 33 to float stably next to the impeller 24. When the impeller 24 drives the zinc liquid to flow, the scum flows and adheres to the surface of the collection block 33.

[0031] The collecting block 33 is an irregular block with a rough surface. When the scum flows over the surface of the collecting block 33, it is easy to stick to the collecting block 33. When a lot of scum sticks to the surface of the collecting block 33, the collecting block 33 is lifted to lift the scum. This process is repeated to clean the scum on the surface of the zinc pool.

[0032] Specifically, when using this impurity removal mechanism, the electric hoist 32 is started to lift the collection block 33 and then slowly put it into the zinc pool 1. The power motor 22 is started to rotate, and the rotating shaft 23 drives the paddle wheel 24 to rotate, thereby pushing the zinc liquid to flow. The flowing zinc liquid carries the scum to be adsorbed onto the collection block 33, and the scum is adhered to the surface of the collection block 33. At the same time, the rotating shaft 23 rotates and drives the scraper 251 to move up and down along the spiral slide 231, so that the scum adhering to the support rod 212, guide column 214 and the outer peripheral surface of the rotating shaft 23 is detached, and the scraper 253 can scrape off the scum on the bottom surface of the scraper 251.

[0033] In summary, the zinc plating tank impurity removal mechanism provided by this utility model drives the zinc liquid to flow through the impeller 24. By setting the suspended collection block 33 in the flow direction of the zinc liquid, it is beneficial to collect scum. After the collection block 33 is lifted and cleaned, it can be put back into the zinc tank for repeated collection, which improves the zinc liquid impurity removal efficiency. Moreover, there is no need to use a filter screen structure, avoiding the complicated operation of cleaning the filter screen.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
