Description

Technical Field

[0001] This utility model belongs to the technical field of metallurgical fuel processing equipment, and in particular relates to a multi-stage diversion device for composite fuel used in sintering. Background Technology

[0002] Traditional sintering production lines in ironmaking plants are configured with two fuel bins and four flux bins, using a single fuel and two fluxes. This configuration is sufficient for daily maintenance of the fuel and flux mixing backup system and for responding to equipment malfunctions. However, with changes in the operating environment, the frequency and amount of mixing two fluxes have decreased, and the use of more than two fuels has become the norm. The fuel mixing system has become a crucial factor in the stability and safety of the production system. Traditional configurations can easily lead to situations where a particular fuel cannot be delivered to the mixing bin of the sintering machine for even mixing with other raw materials, causing the sintering machine to shut down, resulting in emissions exceeding standards and causing environmental incidents. At the same time, processing multiple fuels in the same fuel bin and frequent bin transfers can easily lead to mixing accidents. Utility Model Content

[0003] The purpose of this invention is to provide a multi-stage diversion device for composite fuels used in sintering, which solves the problems of traditional configurations that easily cause sintering machine shutdowns due to the inability of a certain fuel to be delivered to the sintering mixing bin, and frequent bin transfers that easily lead to mixing accidents.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multi-stage diversion device for composite fuel used in sintering includes a dust collection hood, fuel bin A, fuel bin B, fuel bin C, and belt conveyors. The dust collection hood has three discharge ports at its bottom, with any two discharge ports slidably connected to baffles. The baffles slidably block any two discharge ports. The three discharge ports correspond to fuel bins A, B, and C, respectively. Belt conveyors are connected between the dust collection hood and fuel bin A, and between the dust collection hood and fuel bin C. A hollow, irregularly shaped guide cover is installed at the top of fuel bin C. The belt conveyors and baffles are interlocked with an electrical control system.

[0005] Preferably, the irregularly shaped guide cover includes an upper part and a lower part. The upper part is a cuboid with equal length and width, and the lower part is a hexagonal pyramid with the top surface of the pyramid being the same as the bottom surface of the upper part. The bottom surface is a regular hexagon with a side length greater than that of the top surface.

[0006] Working principle: After starting the machine, load the required fuel into the dust collection hood. Move the discharge port baffle according to the type of fuel to allow the fuel to enter the corresponding fuel bin. For example, when adding fuel A, move the baffle to the corresponding discharge ports of fuel bins B and C. Fuel A enters fuel bin A through the discharge port. The hollow irregular-shaped guide cover at the top of fuel bin C has an enlarged hexagonal pyramidal cross-section at the bottom to prevent the material flow from impacting the lining of fuel bin C. Multiple fuels can be mixed with other raw materials in the mixing bin as needed. Multiple fuels can be added at one start-up, reducing the workload of workers.

[0007] The beneficial effects achieved by this utility model are as follows: (1) By adding baffles, belt conveyors and fuel bins, the fuel dispensing system is changed from 2 sets to 3 sets, which improves the fuel storage capacity of the sintering batching room. The 3 sets of fuel dispensing systems dispense fuel separately, so that the fuel distribution in the mixing bin is more dispersed and segregated, which is conducive to uniform heat distribution, achieving homogeneous sintering and avoiding sintering machine shutdown. At the same time, the same fuel is dispensed and stored in the same fuel bin, eliminating the need for bin transfer and avoiding mixing. (2) The hollow irregular-shaped guide cover prevents the material flow from impacting the liner of fuel tank C, thus extending the service life of fuel tank C; (3) Multiple fuels can be added in one start-up without the need for transfer, which reduces the workload of workers and lowers the equipment uptime and personnel operation risks.

[0010] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0011] like Figure 1-2As shown, a multi-stage diversion device for composite fuel used in sintering includes a dust collection hood 1, fuel A silo 2, fuel B silo 3, fuel C silo 4, and a belt conveyor 5. The dust collection hood 1 has three discharge ports at its bottom, with any two of these ports slidably connected to baffles 6. The baffles 6 slidably block any two of the three discharge ports. The three discharge ports correspond to fuel A silo 2, fuel B silo 3, and fuel C silo 4, respectively. Belt conveyors 5 are connected between the dust collection hood 1 and fuel A silo 2, and between the dust collection hood 1 and fuel C silo 4. A hollow, irregularly shaped guide cover 7 is installed at the top of the hopper 4. The belt conveyor 5 and the baffle 6 are interlocked with the electrical control system. The irregularly shaped guide cover 7 consists of an upper part and a lower part. The upper part is a cuboid with equal length and width, and the lower part is a hexagonal pyramid. The top surface of the hexagonal pyramid is the same as the bottom surface of the upper part, and the bottom surface is a regular hexagon with a side length greater than that of the top surface. The discharge port is flexibly controlled by the baffle, so that the material flow can be transported to the corresponding fuel hopper as needed. The hollow, irregularly shaped guide cover expands the cross-section to prevent the material flow from impacting the liner of fuel hopper C at the drop point.
