[0002] High-calcium aluminum slag balls are an additive used in the steelmaking industry. They are suitable for deoxidation during the smelting of various steels, including ordinary steel, alloy steel, and special steel. By utilizing the high activity of metallic aluminum and alumina, they achieve deep deoxidation of molten steel, resulting in smokeless smelting and improving the ductility and polishing performance of steel. However, a special feeding device is required during the smelting process to put the high-calcium aluminum slag balls into the furnace to achieve safe and automated production.

[0003] However, the high-calcium aluminum slag ball feeding device currently used in the steelmaking field still has some defects in use. It cannot effectively cool the high-calcium aluminum slag balls at high temperature during the feeding process, which makes it easy for slag to fall off.

[0004] A novel quantitative feeding device for high-calcium aluminum slag balls with a cooling mechanism is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quantitative feeding device for high-calcium aluminum slag balls with a cooling mechanism, comprising a feeding frame, a first support fixedly connected to the left side of the feeding frame, a second support fixedly connected to the right side of the feeding frame, and a cooling mechanism for automatically cooling the high-calcium aluminum slag balls provided inside the feeding frame.

[0007] The cooling mechanism includes a fan. The top of the inside of the feeding frame is connected to the fan. An air inlet is fixedly connected to the top of the feeding frame. Three sets of connecting plates are provided at the bottom of the inside of the feeding frame. A guide rod is fixedly connected to the top of the connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the high-calcium aluminum slag ball quantitative feeding device with cooling mechanism not only realizes automatic cooling of high-calcium aluminum slag balls and quantitative feeding, but also realizes accelerated feeding.

[0016] (1) By setting up a fan, air inlet, guide rod and connecting plate, when feeding, the high calcium aluminum slag ball will slide to one side through the top of the guide rod. During the sliding process, the fan at the top of the feeding frame is started. After the fan is started, air can be drawn in through the air inlet and then blown out, thereby quickly cooling the high calcium aluminum slag ball at the top of the guide rod. The gap between multiple sets of guide rods can keep the air flowing to improve the cooling effect. Controlling the slow sliding can increase the cooling time to further improve the cooling effect, thus realizing automatic cooling of the high calcium aluminum slag ball;

[0017] (2) By setting up a guide rod, connecting plate, connecting sleeve, first bracket, cylinder, support sleeve, second bracket, fixed shaft, U-shaped frame and push rod, high calcium aluminum slag balls are discharged from the discharge port and fall on the top of the guide rod during feeding. The guide rod can separate a large number of high calcium aluminum slag balls. The start cylinder lifts the left side of the guide rod through the U-shaped frame and push rod, so that the right side is lowered, so that the high calcium aluminum slag balls slide to the right at the top of the guide rod. The high calcium aluminum slag balls separated into rows are evenly fed down. When the feeding amount is reached, the start cylinder drives the left side of the guide rod to fall down, so that it is put into the feeding frame and the right side is closed to stop feeding. By uniform feeding speed and controlling feeding time, quantitative feeding can be maintained, and quantitative feeding can be realized.

[0018] (3) By setting up a feed inlet, a discharge inlet, a partition, a vibrating motor, a fixed column, a fixed plate, a support spring, and a fixed ring, the high-calcium aluminum slag balls are first poured into the feed inlet during feeding. The feed inlet guides the high-calcium aluminum slag balls into the discharge inlet. The top of the partition inside the discharge inlet has an arc-shaped structure, which can first separate the high-calcium aluminum slag balls into groups and send them into the feeding frame. At the same time, the vibrating motor at the bottom of the feed inlet is started. The vibrating motor drives the feed inlet to vibrate, which can prevent blockage during feeding. The support springs at the bottom of the fixed plates at both ends of the feed inlet are connected to the fixed ring, which can support the feed inlet and play a buffering role. The fixed column at the bottom of the fixed plate is attached to the inside of the fixed ring, which can prevent the feed inlet from shaking. This achieves accelerated feeding and prevents blockage.

[0034] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, during feeding, high-calcium aluminum slag balls are discharged from the feed port 5 and fall onto the top of the guide rod 8. The guide rod 8 can separate a large number of high-calcium aluminum slag balls. The start cylinder 12 lifts the left side of the guide rod 8 through the U-shaped frame 20 and the push rod 21, causing the right side to lower, so that the high-calcium aluminum slag balls slide to the right at the top of the guide rod 8.

[0038] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, during feeding, high-calcium aluminum slag balls are first poured into the feed inlet 4. The feed inlet 4 guides the high-calcium aluminum slag balls into the discharge port 5. The top of the partition plate 6 inside the discharge port 5 has an arc-shaped structure, which can first separate the high-calcium aluminum slag balls into groups and send them into the feeding frame 1. At the same time, the vibration motor 7 at the bottom of the feed inlet 4 is started. The vibration motor 7 drives the feed inlet 4 to vibrate, which can prevent blockage during feeding.

[0039] Working Principle: In use, the high-calcium aluminum slag balls are first poured into the feed inlet 4. The feed inlet 4 guides the high-calcium aluminum slag balls into the discharge inlet 5. The top of the partition plate 6 inside the discharge inlet 5 has an arc-shaped structure, which can separate the high-calcium aluminum slag balls into groups and feed them into the feeding frame 1. Simultaneously, the vibration motor 7 at the bottom of the feed inlet 4 is activated. The vibration motor 7 drives the feed inlet 4 to vibrate, preventing blockage during discharge. The support springs 18 at the bottom of the fixing plates 17 at both ends of the feed inlet 4 are connected to the fixing rings 19, which can support the feed inlet 4 and provide a buffering effect. The fixing posts 16 at the bottom of the fixing plates 17 fit inside the fixing rings 19 to prevent the feed inlet 4 from shaking. The high-calcium aluminum slag balls are discharged from the discharge inlet 5 and fall onto the top of the guide rod 8. The guide rod 8 can separate a large number of high-calcium aluminum slag balls. The starting cylinder 12 is activated through the U-shaped frame 2. 0 and push rod 21 lift the left side of the guide rod 8, causing the right side to lower, thus allowing the high-calcium aluminum slag balls to slide to the right at the top of the guide rod 8. The high-calcium aluminum slag balls, separated into rows, are evenly fed down. When the feeding amount is reached, cylinder 12 is activated to drive the left side of the guide rod 8 down, causing it to be drawn into the feeding frame 1. The right side is closed to stop feeding. By uniform feeding speed and controlling the feeding time, a quantitative feeding can be maintained. During feeding, the high-calcium aluminum slag balls will slide to one side past the top of the guide rod 8. During the sliding process, the fan 2 at the top of the feeding frame 1 is activated. After the fan 2 is activated, air can be drawn in through the air inlet 3 and then blown out, thereby quickly cooling the high-calcium aluminum slag balls at the top of the guide rod 8. The gaps between multiple sets of guide rods 8 can maintain air circulation to improve the cooling effect. Controlling the slow sliding can increase the cooling time to further improve the cooling effect.
