Description

Technical Field

[0001] This utility model belongs to the field of galvanizing technology, and particularly relates to a stirring-type hot-dip galvanizing tank that ensures highly uniform galvanizing. Background Technology

[0002] In the field of metallurgical engineering, the galvanizing tank is a core piece of equipment in the hot-dip galvanizing process, and its performance directly affects the quality of galvanized products. Hot-dip galvanizing is widely used in metal product processing due to its excellent corrosion resistance and aesthetic appeal. However, traditional hot-dip galvanizing tanks face some significant technical challenges during operation.

[0003] First, during the heating process, a layer of zinc oxide dross easily forms on the surface of the molten zinc. This dross not only affects the smoothness and adhesion of the galvanized layer, but may also cause coating defects and reduce product quality. Existing hot-dip galvanizing tanks usually rely on manual operation to deal with this zinc oxide dross. That is, workers need to enter the tank or the top of it with hand tools to scrape and clean it. This method is not only labor-intensive and inefficient, but also poses safety risks, such as high-temperature burns and zinc splashing.

[0004] Secondly, the uniformity of the zinc bath is also one of the key factors affecting the quality of galvanizing. If the zinc bath is not distributed evenly during the galvanizing process, it will result in uneven thickness of the galvanized layer, which will affect the overall performance and appearance of the product. However, most existing hot-dip galvanizing tanks lack an effective stirring mechanism and cannot ensure the uniform distribution of the zinc bath throughout the tank. In this case, even if the parameters such as the temperature and composition of the zinc bath are properly controlled, it is difficult to guarantee the high quality of the galvanized layer.

[0005] Therefore, it is essential to invent a stirring-type hot-dip galvanizing bath that ensures highly uniform galvanizing. Utility Model Content

[0006] The purpose of this invention is to provide a stirring-type hot-dip galvanizing tank that ensures highly uniform galvanizing, thereby solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a stirring-type hot-dip galvanizing tank for ensuring high uniformity of galvanizing. It includes a tank body, a liquid level column, a first lead screw, a first motor, a slag scraping mechanism, a stirring mechanism, and slide rails. The tank body is fixed to the ground with expansion bolts, and a heating mechanism is bolted to the inner wall of the tank body. The liquid level column is bolted to the inner wall of the tank body, and several liquid level sensors are bolted to the outer surface of the liquid level column. All liquid level sensors are connected to an external production computer via data cables. First lead screws are respectively installed on both sides of the tank body. The outer surfaces of both ends of the first lead screws are rotatably connected to the tank body via support bearings, and one end of the first lead screw is fixed to the output end of the first motor. The first motor is bolted to the outer surface of the tank body. Slide rails are bolted to both sides of the tank body, and a slag scraping mechanism is slidably mounted on the outer surface of the slide rails. The slag scraping mechanism is located on the upper side of the tank body, and the first lead screw passes through the interior of the slag scraping mechanism via threaded engagement. A stirring mechanism is fixed inside the tank body.

[0009] Furthermore, the slag scraping mechanism includes a drive shaft, a fixed plate, a second motor, a sleeve, and an arc-shaped plate. The drive shaft is located on the upper side of the tank, and both ends of the drive shaft are rotatably connected to the corresponding fixed plates via support bearings. The interior of the fixed plates is threaded with first lead screws, and the fixed plates are slidably connected to corresponding slide rails. The outer side of the drive shaft is bolted to a sleeve, and the outer side of the sleeve is welded to an arc-shaped plate. The arc-shaped plate is arc-shaped, and its interior has several through holes. This configuration, with the cooperation of the second motor and the drive shaft, can push the zinc oxide on the upper surface of the zinc liquid inside the tank to one end of the tank, and facilitates the removal of the zinc oxide by the operator.

[0010] Furthermore, the stirring mechanism includes a second lead screw, a third motor, a scraper, and an agitator. The second lead screw is rotatably mounted inside the tank via a support bearing, and one end of the second lead screw is fixed to the output end of the third motor, which is bolted to the outer side of the tank. The second lead screw passes through the scraper via a threaded engagement, wherein the outer side of the scraper is fitted against the inside of the tank, and the agitator is bolted to the inside of the scraper. This arrangement can prevent the zinc liquid from adsorbing onto the inner wall of the tank and can ensure the uniformity of the zinc liquid inside the tank.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The slag scraping mechanism of this utility model, when in use, allows the opening of the arc-shaped plate to face one side of the tank through the cooperation of the second motor and the transmission shaft. Then, through the cooperation of the first motor and the first lead screw, the slag scraping mechanism can move from one end of the tank along the slide rail to the other end of the tank. During the movement of the slag scraping mechanism, the arc-shaped plate can push the zinc oxide on the upper surface of the zinc liquid inside the tank to one end of the tank. Then, through the cooperation of the second motor and the transmission column, the opening of the arc-shaped plate is set to face upward, so that the arc-shaped plate can remove the zinc oxide inside the zinc liquid, thereby facilitating the removal of zinc oxide by the operator.

[0013] 2. The stirring mechanism of this utility model, when in use, enables the scraper to reciprocate inside the tank through the cooperation of the third motor and the second lead screw. During the movement of the scraper, the scraper can prevent the zinc liquid from adhering to the inner wall of the tank. At the same time, the scraper and the stirring plate can drive the zinc liquid inside the tank to flow, thereby ensuring the uniformity of the zinc liquid inside the tank.
