Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical sintering, and particularly relates to a magnetic segregation material distribution device for a sintering machine. Background Art

[0002] In the process of metallurgical sintering production, it is necessary to carry out material distribution on the sintering trolley. High-quality material distribution conditions are conducive to reducing the consumption of sintering solid fuels and reducing carbon emissions. Optimizing the material distribution system can improve the material distribution quality, which is conducive to the full crystallization of sintered minerals, improving the structure, and improving the quality of sintered ore, thereby improving the metallurgical performance of the blast furnace.

[0003] Traditional feeding methods include bar screen chute feeding, grid screen chute feeding, airflow feeding, etc. Most of them adjust the material quantity and material layer structure by changing the running speed of the sintering machine round roller and moving the feeding roller, or make the sintering machine feeding width direction uniform by adjusting the baffle or gate. At present, people prefer to adopt the segregation feeding method, that is, larger particles are distributed to the bottom of the trolley, and smaller particles are gradually concentrated to the upper part, so as to achieve a segregation feeding with a gradual decrease in particles from the bottom of the material layer to the surface. Segregation feeding currently mostly adopts the mechanical sieve distribution method. This feeding method requires screening out materials of different particle sizes and then feeding them layer by layer according to the particle size of the materials, which is cumbersome to operate. Summary of the invention

The device uses a magnetic field to make magnetite materials of different particle sizes fall at different distances, so that they fall on the sintering trolley according to their particle sizes, and then the materials are distributed on the sintering trolley.

[0006] Furthermore, in the above-mentioned sintering machine magnetic segregation distribution device, the distribution roller is a hollow sleeve.

[0007] Furthermore, in the above-mentioned sintering machine magnetic segregation distribution device, the number of distribution rollers is nine or twelve.

[0008] Furthermore, in the above-mentioned sintering machine magnetic segregation feeding device, a coupling wound with a magnetic coil is arranged inside every other feeding roller.

[0009] Furthermore, in the above-mentioned sintering machine magnetic segregation distribution device, the magnetic coil is wound by a segmented winding method, with 20 to 30 coils as one segment, which are evenly distributed on the coupling.

[0010] Furthermore, in the above-mentioned sintering machine magnetic segregation distribution device, after the magnetic coils are energized, the magnetic field directions of the coils on different couplings are consistent or the magnetic field directions of the coils on different couplings are inconsistent.

[0016] A sintering machine magnetic segregation distribution device comprises a material trough 1, a feeder 2, a distribution roller 3, a coupling 4, and a magnetic coil 5. The material trough is arranged above the feeder, the feeder is arranged above the distribution roller, there are nine distribution rollers, which are arranged in parallel and tilted from bottom to top, the distribution roller is a hollow sleeve, the magnetic coil is wound on the coupling, the distribution roller is sleeved on the outside of the coupling wound with the magnetic coil, the magnetic coil is wound by a segmented winding method, with 20 to 30 coils as a segment, which are evenly distributed on the coupling, the magnetic coil is connected to an external power supply, the coupling is transmission-connected to a power mechanism, and after the magnetic coil is energized, the magnetic field directions of the coils on different couplings can be controlled to be consistent or inconsistent according to different currents.

[0017] The method of using the device is as follows: the sintered material containing magnetite in the material trough 1 falls onto the distribution roller through the feeder 2. Since the magnetic coil 5 in the distribution roller 3 is energized, the magnetic field change in the distribution roller is controlled by changing the size, direction and frequency of the current. The magnetic stirring is performed by magnetic non-mechanical contact so that the mixed material is subjected to the braking effect of the magnetic force during the material dropping process. The mixed material with different particle sizes is subjected to different braking effects, and particles of different sizes are stratified during the distribution process to achieve segregation. The sintered material with larger particle size falls first and falls farther away from the distribution roller, and the sintered material with smaller particle size falls subsequently and falls closer to the distribution roller. Since the sintering trolley for receiving the material is constantly running, it receives the sintered material with larger particle size when it runs farther away from the distribution roller. When it runs closer to the distribution roller, the sintered material with smaller particle size falls on the sintered material with larger particle size on the sintering trolley, thereby achieving reasonable segregation of the upper, middle and lower force of the sintered material distribution layer.
