Description

Technical Field

[0001] This utility model belongs to the field of converter tapping and feeding technology, and in particular relates to a feeding device suitable for converter alloys. Background Technology

[0002] In the steelmaking process, scrap aluminum blocks are added after the steel is tapped from the converter to adjust the composition of the molten steel. To ensure the quality of the molten steel, reduce production costs and the intensity of manual labor, the alloy addition during production is changed from scrap aluminum blocks to aluminum ingots. The feeding device consists of a vertical section pipe and an inclined pipe. To increase buffering and reduce the impact of materials on the vertical section pipe and the inclined pipe, wear-resistant plates are laid inside the vertical section pipe and the inclined pipe. At the same time, there is an angle between the rotating chute and the inclined pipe. The aluminum ingots are added from the vertical section pipe and come into contact with the wear-resistant plates during the process. The edges of the aluminum ingots are easily blocked at the angle between the rotating chute and the inclined pipe, which affects production. Utility Model Content

[0003] The purpose of this invention is to provide a feeding device suitable for converter alloys, which solves the problem that aluminum ingot edges are easily blocked at the angles of the rotating chute and inclined tube, affecting production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A charging device for converter alloys includes a feed inlet and a rotating mechanism. The rotating mechanism includes an alloy material tube, a motor, and a cycloidal pinwheel reducer. The bottom end of the feed inlet is connected to the alloy material tube. A gear disk is fixed around the alloy material tube. The gear disk is chain-driven to the output end of the cycloidal pinwheel reducer. The input end of the cycloidal pinwheel reducer is connected to the motor. The bottom end of the alloy material tube is connected to a rotating chute via a flange. The bottom end of the rotating chute is slidably connected to an inclined tube. The inclined tube extends in a straight line along the upper right to be level with the bottom of the cycloidal pinwheel reducer. A support base is fixed to the bottom of the inclined tube and located in the direction of the center line of the rotating chute.

[0006] Preferably, the bottom of the inclined tube is reinforced with a shell.

[0007] Preferably, the angle of inclination of the inclined tube to the horizontal plane is 50 degrees.

[0008] Preferably, both the alloy tube and the inclined tube are seamless steel tubes.

[0009] Feeding process: During production, alloy blocks are added from the feed inlet. The alloy blocks are small and will not get stuck at the angle between the rotating chute and the inclined tube. Aluminum ingots are added from the top of the inclined tube. The aluminum ingots enter in a straight line along the inclined tube and will not get stuck.

[0010] The beneficial effects achieved by this utility model are as follows:

[0011] (1) The inclined tube extends in a straight line along the upper right. The aluminum ingot is added from the inclined tube opening. The aluminum ingot enters in a straight line along the direction of the inclined tube to avoid the problem of aluminum ingot jamming and affecting production due to the angle between the rotating chute and the inclined tube.

[0012] (2) A support base is fixed at the bottom of the inclined tube in the direction of the center line of the rotary chute to prevent the inclined tube from shaking during the feeding process and to enhance the stability of the device; the alloy material tube and the rotary chute are connected by a flange to facilitate the replacement of the alloy chute.

[0013] (3) During the feeding process, aluminum ingots and other alloys cause wear to the inclined tube. The service life of the inclined tube is enhanced by the tube shell on the lower outer surface of the inclined tube.

[0014] (4) The device has a simple structure, is easy to operate, and improves production efficiency. Attached Figure Description

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, a charging device suitable for converter alloys includes a feed inlet 1 and a rotating mechanism. The rotating mechanism includes an alloy material tube 2, a motor 3, and a cycloidal pinwheel reducer 4. The bottom end of the feed inlet 1 is connected to the alloy material tube 2. A gear disk 5 is fixed around the alloy material tube 2. The gear disk 5 is chain-driven to the output end of the cycloidal pinwheel reducer 4. The input end of the cycloidal pinwheel reducer 4 is connected to the motor 3. The bottom end of the alloy material tube 2 is connected to a rotating chute 6 via a flange 10. The bottom end of the rotating chute 6 is slidably connected to an inclined tube 7. The inclined tube 7 extends straight up and to the right until it is flush with the bottom height of the cycloidal pinwheel reducer 4. 7. The bottom of the outer tube shell 9 is reinforced. The bottom of the tube shell 9 is fixed with a support seat 8 located in the direction of the center line of the rotating chute 6. The inclined tube 7 is inclined at an angle of 50 degrees to the horizontal plane. The gear disc is driven to rotate by a motor and a cycloidal pinwheel reducer, so that the alloy material tube rotates, achieving uniform material distribution and improving production efficiency. By extending the inclined tube, the material inlet is increased. Aluminum ingots are added from the inlet of the inclined tube, and jamming is prevented along the direction of the inclined tube. The bottom of the inclined tube is reinforced by the tube shell to reduce the wear of the inclined tube caused by the material addition. The support seat supports and fixes the bottom of the inclined tube to prevent the inclined tube from rotating and moving, which is conducive to the stable feeding of aluminum ingots into the furnace.
