Description

Technical Field

[0001] This utility model relates to the field of metal recycling technology, specifically to a device for recycling hot-dip galvanized slag. Background Technology

[0002] In modern industrial production, hot-dip galvanizing is a widely used metal surface treatment technology, extensively used for the corrosion protection of steel products. It involves immersing steel products in molten zinc, causing a metallurgical reaction between zinc and the steel surface to form a dense zinc-iron alloy coating. This effectively prevents the steel from contacting the external environment, significantly improving the corrosion resistance of steel products and extending their service life. However, a certain amount of hot-dip galvanizing dross is inevitably generated during the production process. This dross mainly consists of zinc, iron, and small amounts of other impurities. Its formation is primarily due to the reaction between the molten zinc and the steel surface during galvanizing, which generates zinc-iron alloy compounds. These compounds gradually accumulate in the molten zinc, forming dross. Since zinc is a metal resource with high economic value, and its production process consumes a large amount of energy and raw materials, the recycling of hot-dip galvanizing dross has significant economic and environmental implications.

[0003] Existing hot-dip galvanizing slag recycling and reuse devices mainly adopt a process of crushing followed by reaction. First, the collected hot-dip galvanizing slag is crushed into smaller particles to increase the surface area of ​​the slag and improve the efficiency and completeness of the subsequent reaction. The crushed slag particles enter the reaction tank and react with specific chemical reagents. Most recycling and reuse devices consist of a crushing box, a filter plate, and a reaction tank. During crushing, large and small slag particles are produced. However, some existing recycling and reuse devices do not automatically discharge the large slag particles filtered from the top of the filter plate, affecting the recycling efficiency. Therefore, we propose a hot-dip galvanizing slag recycling and reuse device to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a hot-dip galvanizing slag recycling device, which has the following beneficial effects:

[0016] This invention utilizes a motor to drive an eccentric wheel to rotate. The first half of the eccentric wheel's rotation compresses the ball bearings, which in turn cause a moving rod to slide on a fixed rod. The moving rod, via a connecting block, moves a flexible steel rope, which in turn causes a moving plate to slide on a U-shaped rod. The moving plate, through a filter plate, moves a fan-shaped plate. Large zinc dross particles on the filter plate can slide over the arc surface of the fan-shaped plate, resulting in relative sliding between the filter plate and the large zinc dross particles. Continuous operation of the motor drives the filter plate to move left and right in a cyclical manner, gradually pushing the large zinc dross particles out of the crushing box and into the collection box. The large zinc dross particles filtered from the top of the filter plate are automatically discharged. Attached Figure Description

A fixed pulley is mounted on the top of the rotating part. A flexible steel rope 8 is fixedly connected to the top of the connecting block 7. A second L-shaped plate 9 is fixedly connected to the left side of the crushing box 2. A motor 10 is fixedly connected to the inner wall of the left side of the second L-shaped plate 9. An eccentric wheel 11 is fixedly connected to the output shaft of the motor 10. A conveying pipe 23 is connected and fixed between the reaction tank body 1 and the crushing box 2. A ball bearing 12 is embedded at the top of the moving rod 5. The eccentric wheel 11 and the ball bearing 12 are in rolling contact. Two U-shaped rods 13 are welded to the left side of the crushing box 2. A moving plate 14 is slidably connected to the U-shaped rods 13. The end of the flexible steel rope 8 passes around the bottom of the fixed pulley and is fixedly connected to one side of the moving plate 14.

[0027] In some embodiments, a second spring 15 is fixedly connected between the inner wall of one side of the U-shaped rod 13 and one side of the movable plate 14.

[0028] In some embodiments, a crushing roller 16 is rotatably connected between the inner walls of the two sides of the crushing box 2, and the end of the crushing roller 16 extends to the outside of the crushing box 2 and is fixedly connected to the output shaft of the motor 10.

[0029] Motor 10 drives crushing roller 16 to crush zinc slag, which produces large and small zinc slag particles.

[0030] In some embodiments, rectangular holes 17 are provided on both inner walls of the crushing box 2, and filter plates 18 are slidably connected to the rectangular holes 17. One side of the filter plate 18 is fixedly connected to one side of the moving plate 14.

[0031] In some embodiments, the filter plate 18 has a plurality of filter holes 19 and a plurality of sector plates 20 are fixedly connected to the filter plate 18, with one side of the sector plate 20 being an arc surface.

[0032] In some embodiments, a fixing plate 21 is fixedly connected to the right side of the crushing box 2, and a collection box 22 with an open top is movably contacted on the fixing plate 21. The top of the crushing box 2 is provided with a feed inlet 24.

[0033] Working principle or structural principle: During use, the motor 10 is started, and the zinc slag is poured into the crushing box 2 through the feed inlet 24. The motor 10 drives the crushing roller 16 to crush the zinc slag, producing large and small zinc slag particles. The small zinc slag particles enter the conveying pipe 23 through the filter hole 19 and are conveyed into the reaction tank body 1 for reaction. The large zinc slag particles fall onto the filter plate 18. At the same time, the motor 10 drives the eccentric wheel 11 to rotate. The first half-turn of the eccentric wheel 11 squeezes the ball bearing 12. Under the action of the squeezing force, the ball bearing 12 drives the moving rod 5 to slide on the fixed rod 4 and compress the first spring 6. The moving rod 5 drives the flexible steel rope 8 to move through the connecting block 7. The flexible steel rope 8 drives the moving plate 14 to slide on the U-shaped rod 13 and compress the second spring 15. The moving plate 14 drives the fan-shaped plate 20 to move to the left through the filter plate 18. When the filter plate 18 moves, the large zinc slag particles on the filter plate 18 can slide over the arc surface of the fan-shaped plate 20. At this time, relative sliding occurs between the filter plate 18 and the large zinc slag particles. When the eccentric wheel 11 rotates to the second half turn, it gradually relaxes the pressure on the ball bearing 12. At this time, the second spring 15, which is in a compressed state, returns to its original position. The second spring 15 drives the filter plate 18 to move to the right through the moving plate 14. The filter plate 18 drives the fan-shaped plate 20 to move. The fan-shaped plate 20 can block and drive the large zinc slag particles to move towards the collection box 22. The motor 10 continues to run, which can drive the filter plate 18 to move left and right in a cycle, so that the large zinc slag particles are gradually pushed out of the crushing box 2 and fall into the collection box 22 through the filter plate 18. The filter plate 18, which swings left and right in a cycle, can improve the filtration efficiency. The large particles of waste collected in the collection box 22 are poured back into the crushing box 2 for crushing again.
