Description

Technical Field

[0001] This application relates to the field of blast furnace feeding technology, and more specifically, to a blast furnace feeding device. Background Technology

[0002] Common ironmaking methods include electric arc furnace ironmaking and blast furnace ironmaking. Compared with electric arc furnace ironmaking, blast furnace ironmaking has lower energy consumption and higher economic benefits. During the ironmaking process, a charging device is required to charge the furnace charge.

[0003] The prior art CN218666125U discloses a blast furnace charging device, including a storage bin, a auger conveyor, a tilting assembly and a discharge hopper. In use, the auger conveyor transports the material in the storage bin to the discharge hopper, and the discharge hopper sends the material into the blast furnace.

[0004] To ensure the efficient operation of the auger conveyor and extend its service life, regular internal maintenance is required. However, in the existing technology CN218666125U, the auger conveyor is fixedly installed on the support frame, which makes it difficult to move the auger conveyor, increases the difficulty of maintenance, and the maintenance time is long. During the maintenance period, the auger conveyor cannot continue to supply material to the blast furnace, which affects the production process. Utility Model Content

[0005] The purpose of this application is to provide a blast furnace feeding device that uses another auger conveyor to feed materials when one of the auger conveyors is under maintenance, thereby avoiding disruption to production.

[0007] A blast furnace feeding device includes a track, two branch tracks, two trolleys, and a auger conveyor fixed to the trolleys by multiple first support rods. The branch tracks are connected to the track, and the trolleys run on the track or the branch tracks.

[0008] Preferably, the trolley includes a base and four omnidirectional self-locking wheels. The first support rod is disposed on the base, and the four omnidirectional self-locking wheels are respectively disposed at the four bottom corners of the base. The omnidirectional self-locking wheels run on the track and the branch line.

[0009] Preferably, a baffle is provided at the end of the track.

[0010] Preferably, a pretreatment box is fixed on the trolley by multiple second support rods. The upper end of the pretreatment box is provided with a feed pipe and a motor, and the lower end of the pretreatment box is provided with a discharge pipe. The discharge pipe is connected to the auger conveyor. The interior of the pretreatment box is provided with a dispersing component, and the motor drives the dispersing component to rotate.

[0011] Preferably, the dispersing assembly includes a rotating rod and a plurality of dispersing rods. The rotating rod is disposed inside the pretreatment box, the upper end of the rotating rod passes through the pretreatment box, the rotating rod is connected to the motor, and the dispersing rods are disposed on the rotating rod.

[0012] Preferably, the dispersing component further includes a spiral blade, which is disposed at the lower end of the rotating rod and extends into the interior of the discharge pipe.

[0013] Preferably, the lower end of the pretreatment box has a funnel-shaped structure.

[0014] The beneficial effects of this application are:

[0015] When the blast furnace feeding device provided in this application needs to be maintained by one of the auger conveyors, the trolley carrying the auger conveyor is moved to one of the branch tracks, and then the trolley on the other branch track is moved to the track, and the other auger conveyor is used to feed the blast furnace, thereby avoiding affecting the production process.

[0027] Example

[0028] like Figure 1 and Figure 2 As shown, the blast furnace feeding device described in this application embodiment includes a track 1, two branch tracks 2, two trolleys 3, and a auger conveyor 5 fixed to the trolleys 3 by multiple first support rods 4. The auger conveyor 5 is used to feed materials to the blast furnace. The branch tracks 2 are connected to the track 1, and the trolleys 3 run on the track 1 or the branch tracks 2.

[0029] In use, the auger conveyor 5 on one of the trolleys 3 is used to feed the blast furnace. When maintenance is required on the auger conveyor 5, the trolley 3 carrying the auger conveyor 5 is moved to one of the branch tracks 2, and then the trolley 3 on the other branch track 2 is moved to the track 1, and the other auger conveyor 5 is used to feed the blast furnace, thereby avoiding affecting production.

[0030] In this embodiment, the trolley 3 includes a base 6 and four universal self-locking wheels 7. The first support rod 4 is set on the base 6, and the four universal self-locking wheels 7 are respectively set at the four bottom corners of the base 6. The universal self-locking wheels 7 run on the track 1 and the branch track 2. The universal self-locking wheels 7 (i.e. universal wheels with braking or locking functions) combine the flexibility and locking function of ordinary universal wheels, and can fix the position of the equipment or restrict the direction of movement when needed.

[0031] In this embodiment, a baffle 8 is provided at the end of the track 1, which is used to limit the movement of the trolley 3.

[0032] In this embodiment, a pretreatment box 10 is fixed on the trolley 3 by multiple second support rods 9. The upper end of the pretreatment box 10 is provided with a feed pipe 11 and a motor 12, and the lower end of the pretreatment box 10 is provided with a discharge pipe 13. The discharge pipe 13 is connected to the auger conveyor 5. The interior of the pretreatment box 10 is provided with a dispersing component 14, and the motor 12 drives the dispersing component 14 to rotate.

[0033] In use, the material is fed into the pretreatment box 10 through the feed pipe 11. The motor 12 drives the dispersing component 14 to rotate. The dispersing component 14 disperses the material to prevent clumping. The dispersed material enters the auger conveyor 5 through the discharge pipe 13. The auger conveyor 5 transports the material to the blast furnace.

[0034] In this embodiment, the dispersing component 14 includes a rotating rod 15 and a plurality of dispersing rods 16. The rotating rod 15 is disposed inside the pretreatment box 10, the upper end of the rotating rod 15 penetrates through the pretreatment box 10, the rotating rod 15 is connected to the motor 12, and the dispersing rods 16 are disposed on the rotating rod 15.

[0035] In use, the motor 12 drives the rotating rod 15 to rotate, and the rotating rod 15 drives the dispersing rod 16 to rotate. While the dispersing rod 16 rotates, it disperses the material to prevent the material from clumping.

[0036] In this embodiment, the dispersing component 14 also includes a spiral blade 17, which is disposed at the lower end of the rotating rod 15 and extends into the interior of the discharge pipe 13. When the motor 12 drives the rotating rod 15 to rotate, the spiral blade 17 rotates synchronously to avoid material blockage inside the discharge pipe 13.

[0037] In this embodiment, the lower end of the pretreatment box 10 has a funnel-shaped structure, which facilitates the entry of materials into the discharge pipe 13.

[0038] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
