[0002] Blast furnace smelting is a common smelting method, primarily used for producing iron and steel. A blast furnace is a large-scale smelting facility, typically used by steel companies, to convert raw materials such as iron ore, coke, and limestone into iron and steel. Blast furnace smelting is a crucial process in the steel industry, enabling the large-scale production of iron and steel to meet the needs of industries such as construction, manufacturing, and transportation. Blast furnace smelting boasts advantages such as large scale, high production efficiency, and low cost, making it widely used in steel production. However, blast furnace smelting also generates significant amounts of smoke, exhaust gas, and wastewater, causing environmental pollution problems. Therefore, environmental protection measures and technologies are receiving increasing attention in modern industrial production.

[0003] The existing coke addition process has a relatively high concentration, which makes it impossible to add coke evenly into the blast furnace. The coke reaction uniformity inside the blast furnace is poor, which affects the blast furnace smelting effect. To address this, we propose a charging auxiliary device for efficient utilization of blast furnace coke load. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model achieves the effect of evenly spreading coke into the blast furnace by setting up a feeding hopper, feeding plate A, feeding plate B and feeding plate C. This solves the problem that the concentration of coke addition is relatively high in the existing method, which makes it impossible to add coke evenly into the blast furnace. The coke reaction uniformity in the blast furnace is poor, which affects the smelting effect of the blast furnace. This invention improves the uniformity of coke spreading, thereby ensuring the smelting effect of the blast furnace.

[0016] 2. This utility model achieves the effect of crushing the fed coke by setting up a material box, a feeding hopper and a crushing roller, so as to solve the problem that the coke particle size is not uniform in the existing blast furnace charging, which leads to poor coke charging uniformity and affects the blast furnace smelting effect. It improves the coke charging uniformity, thereby ensuring the blast furnace smelting effect.

[0017] 3. This utility model achieves the effect of screening coke by setting up a screening motor, a screening plate, a movable shaft and a cam to drive the screening plate to vibrate. This solves the problem that the existing coke feed particle size uniformity is poor, which can easily lead to conveyor blockage and affect the subsequent feeding of the material distributor. It reduces the probability of conveyor blockage and thus ensures the normal feeding of the blast furnace. Attached Figure Description
