Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a sintered ore mixing drum. Background Technology

[0002] Sintered ore is an important raw material for ironmaking. It is formed by sintering iron ore powder, fuel, and solvent at high temperatures. Sintered ore is characterized by high strength and good reducibility, which can effectively improve the efficiency and quality of blast furnace ironmaking. In the iron and steel smelting process, the quality of sintered ore plays a crucial role in the entire production process. It not only affects the smooth operation of the blast furnace but also relates to the quality and cost of steel products. Therefore, in order to improve the quality of sintered ore, it is necessary to fully mix various raw materials. At present, when mixing sintered ore, a mixer is generally used to stir and mix the ore. The mixer is equipped with a stirring shaft. By controlling the rotation of the stirring shaft, the ore in the cylinder is stirred. However, in the current mixers, there is generally a certain gap between the blades on the stirring shaft and the cylinder wall. This makes it difficult for the ore at the edge and bottom of the cylinder to be fully stirred, resulting in uneven mixing of the ore after mixing. Utility Model Content

A conical buffer cover 4 is provided at the center position below the corresponding inlet 2 inside the mixing drum 1. The protruding end of the buffer cover 4 is arranged upward. A mixing feeder 5 is provided below the corresponding buffer cover 4 inside the mixing drum 1. The mixing feeder 5 has a narrowing structure with a wider top and a narrower bottom. A discharge port is provided on the bottom wall of the mixing drum 1 at the lower outlet position of the mixing feeder 5. A discharge box 6 is horizontally placed at the bottom of the mixing drum 1. The upper end of the discharge box 6 has an open structure. The feeding start end of the discharge box 6 is installed below the discharge port. A conveyor is provided inside the discharge box 6. A discharge channel 7 is provided at the end of the discharge box 6 away from the discharge port.

[0019] An inclined guide chute 8 is provided on the side wall of the mixing cylinder 1 below the corresponding feed inlet 2. The discharge end of the guide chute 8 is arranged on an inclined slope towards the buffer cover 4.

[0020] The diameter of the buffer cover 4 is smaller than the inner diameter of the mixing cylinder 1. Several connecting rods 9 are evenly distributed on the edge of the buffer cover 4. The buffer cover 4 is fixedly connected to the inner wall of the mixing cylinder 1 through the connecting rods 9.

[0021] The mixing feeder 5 is a cylindrical structure with a reduced diameter. Both the upper and lower ends of the mixing feeder 5 are open. The edge of the upper end of the mixing feeder 5 is fixedly connected to the inner wall of the mixing cylinder 1.

[0022] The bottom wall of the discharge box 6 is an arc-shaped structure. The conveyor is installed at the arc-shaped structure of the discharge box 6. The discharge box 6 has a discharge port 10 on the side away from the discharge port, and the discharge channel 7 is set at the position corresponding to the discharge port 10.

[0023] The conveyor includes a screw conveyor shaft 11 located at the bottom of the discharge box 6. A motor 12 is located on the side of the discharge box 6 near the discharge port. The drive shaft of the motor 12 is connected to one end of the screw conveyor shaft 11.

[0025] The working principle of this utility model is as follows: various sintered ore raw materials are transported by different material conveyors 3. The raw materials enter the interior of the mixing cylinder 1 through the feed port 2. First, various materials slide down along the guide chute 8 to the top of the buffer cover 4. Then, the raw materials slide down the slope on the buffer cover 4 into the mixing feeder. Various raw materials are mixed in the mixing feeder and fall together along the discharge port at the bottom of the mixing cylinder 1 into the discharge box 6. The mixed raw materials fall to the starting end of the conveying in the discharge box 6. At this time, the motor 12 drives the screw conveyor shaft 11 to rotate. As the screw conveyor shaft 11 rotates, it stirs the mixed raw materials and moves them to one side of the discharge channel 7. During the process of conveying the raw materials through the screw conveyor shaft 11, various raw materials are also stirred and mixed. Then, the mixed ore is discharged through the discharge port of the discharge channel 7 and carried out steelmaking operations.
