Description

Technical Field

[0001] This utility model belongs to the field of slag dumping technology, specifically referring to a slag dumping device. Background Technology

[0002] Slag dumping device is a specialized equipment designed to handle various industrial wastes and construction wastes. Its core function is to efficiently and safely transfer, dump, and pre-treat slag. Blast furnace slag is a type of slag. The slag produced by blast furnace smelting is discharged through the slag outlet and flows into a high-temperature resistant slag basin, and then transported to the processing area for treatment. Liquid slag needs to be dumped into a hot quenching tank or crushing equipment.

[0003] In existing technologies, slag pans are typically tilted over to directly dump the slag into the crushing equipment. This method has some drawbacks: the height of the slag pan is fixed during dumping, making it difficult to adjust the tilting height and thus unsuitable for crushing equipment or hot quenching tanks of different heights. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, it is inconvenient to adjust the discharge height of the slag hopper when dumping liquid slag, thus limiting its application range.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a slag dumping device includes a carriage, the carriage is provided with a lifting and adjusting device, the upper end of the lifting and adjusting device is connected to a trough plate, a slag hopper is provided above the trough plate, a unloading and tilting device that can drive the slag hopper to tilt and dump is provided between the slag hopper and the trough plate, and two sets of auxiliary support devices are symmetrically provided at the upper end of the carriage to help fix the slag hopper.

[0006] Furthermore, the lifting and adjusting device includes a motor, which is fixed to the bottom of the interior of the carriage. A lead screw is provided at the output end of the motor. A lifting plate is installed through the carriage. The upper end of the lifting plate is fixed to the trough plate, and the lower end of the lifting plate is provided with an end plate. The lifting plate is threadedly connected to the lead screw. By rotating the lead screw, the lead screw drives the lifting plate to move up and down in the carriage, thereby flexibly adjusting the unloading height of the slag hopper to adapt to crushing equipment or hot quenching tanks of different heights.

[0007] Furthermore, the unloading and tilting device includes a connecting plate, which is fixed to the lower end face of the slag hopper and located in the trough plate. A connecting shaft is fixed to the connecting plate and rotates in the trough plate. A gear is provided at the end of the connecting shaft. Two sets of side plates are fixed to the side wall of the trough plate. An electric push rod is fixed to one of the side plates. A rack passes through the other side plate and meshes with the gear. The rack is pushed by the electric push rod, and the rack meshes with the gear to rotate. The gear drives the connecting shaft to rotate, and the connecting shaft drives the connecting plate to rotate in the trough plate, thereby realizing the reverse unloading of the slag hopper.

[0008] Furthermore, the auxiliary support device includes an electric push rod two, which is fixed to the upper end face of the carriage. The output end of the electric push rod two is connected to a support plate. The support plate can fit against the bottom wall of the slag hopper. A guide rod is provided on the lower end face of the support plate and extends downward through the carriage. By attaching the support plate to the lower end of the slag hopper, the stability of the slag hopper can be ensured during transportation.

[0009] Furthermore, two sets of fixing columns are fixed in the carriage, and the fixing columns pass through the end plate.

[0010] Furthermore, the lower end of the guide rod is provided with an end cap, which can prevent the guide rod from detaching from the carriage.

[0011] Furthermore, the thickness of the connecting plate is equal to the width of the groove in the groove plate, and the lower end of the connecting plate has space inside the bottom of the groove plate to ensure that the connecting plate will not touch the groove plate when rotating.

[0012] The beneficial effects achieved by adopting the above-described structure are as follows:

[0013] 1. This utility model, by setting up a lifting adjustment device, uses a motor to drive the lead screw to rotate, and the lead screw to drive the lifting plate to lift, thereby flexibly adjusting the discharge height of the slag hopper to adapt to different crushing equipment or hot quenching tanks for dumping and unloading.

[0014] 2. This utility model can achieve the unloading and unloading of slag hopper by setting up a unloading and tilting device, which rotates through the meshing of rack and pinion gears. The gears drive the connecting plate to rotate synchronously through the connecting shaft. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1-4 This utility model discloses a slag dumping device, including a carriage 1. The carriage 1 is equipped with a lifting and adjusting device 2. The upper end of the lifting and adjusting device 2 is connected to a trough plate 3. A slag hopper 4 is arranged above the trough plate 3. A discharge and tilting device 5 that can drive the slag hopper 4 to tilt and dump is arranged between the slag hopper 4 and the trough plate 3. Two sets of auxiliary support devices 6 are symmetrically arranged at the upper end of the carriage 1 to help fix the slag hopper 4.

[0023] like Figure 2 The lifting and adjusting device 2 includes a motor 7, which is fixed to the bottom of the interior of the carriage 1. The output end of the motor 7 is provided with a lead screw 8. A lifting plate 9 is installed through the carriage 1. The upper end of the lifting plate 9 is fixed to the trough plate 3. The lower end of the lifting plate 9 is provided with an end plate 10. Two sets of fixing columns 20 are fixed in the carriage 1. The fixing columns 20 are inserted into the end plate 10. The lifting plate 9 is threadedly connected to the lead screw 8. By rotating the lead screw 8, the lead screw 8 drives the lifting plate 9 to move up and down in the carriage 1, so that the unloading height of the slag hopper 4 can be flexibly adjusted to adapt to different height crushing equipment or hot quenching tanks.

[0024] like Figure 1-4 The unloading and tilting device 5 includes a connecting plate 11, which is fixed to the lower end face of the slag hopper 4 and located in the trough plate 3. The thickness of the connecting plate 11 is equal to the width of the trough in the trough plate 3, and the lower end of the connecting plate 11 has space inside the trough plate 3 to ensure that the connecting plate 11 will not touch the trough plate 3 when rotating. A connecting shaft 12 is fixed to the connecting plate 11 and rotates in the trough plate 3. A gear 13 is provided at the end of the connecting shaft 12. Two sets of side plates 14 are fixed to the side wall of the trough plate 3. An electric push rod 15 is fixed to one of the side plates 14, and a rack 16 passes through the other side plate 14 and meshes with the gear 13. The rack 16 is pushed by the electric push rod 15, and the rack 16 meshes with the gear 13 to rotate. The gear 13 drives the connecting shaft 12 to rotate, and the connecting shaft 12 drives the connecting plate 11 to rotate in the trough plate 3, thereby realizing the reverse unloading of the slag hopper 4.

[0025] like Figure 1-3 The auxiliary support device 6 includes an electric push rod 17, which is fixed to the upper surface of the carriage 1. The output end of the electric push rod 17 is connected to a support plate 18, which can fit against the bottom wall of the slag hopper 4. A guide rod 19 is provided on the lower surface of the support plate 18 and extends downward through the carriage 1. An end cap 21 is provided at the lower end of the guide rod 19, which can prevent the guide rod 19 from detaching from the carriage 1. By attaching the support plate 18 to the lower end of the slag hopper 4, the stability of the slag hopper 4 can be ensured during transportation.

[0026] In practical use, after receiving the liquid slag, the slag hopper 4 needs to be transferred to the processing area, such as the hot quenching tank. The slag is poured into the closed tank and sprayed with water to cool it, so that the iron minerals in the slag are pulverized, which is convenient for subsequent magnetic separation and recovery. Alternatively, the liquid slag can be water-quenched and cooled before being poured into the crushing equipment for crushing.

[0027] The slag is transported via the carriage 1. During transport, the support plate 18 is pushed by the electric push rod 2 17, so that the support plate 18 fits against the lower end face of the slag hopper 4, which can ensure the transport stability of the slag hopper 4. When it is necessary to dump the slag in the slag hopper 4, the support plate 18 is first pulled down by the electric push rod 2 17 to move it away from the slag hopper 4 at a suitable distance. Then, by activating the electric push rod 1 15, the rack 16 will slide in the side plate 14. The rack 16 always meshes with the gear 13, driving the gear 13 to rotate. The gear 13 drives the connecting plate 11 to rotate through the connecting shaft 12, so that the connecting plate 11 will drive the slag hopper 4 to flip, realizing the dumping of the slag in the slag hopper 4.

[0028] When it is necessary to adjust the tilting height of the slag hopper 4, the motor 7 is started and the lead screw 8 drives the lifting plate 9 to rise and fall. The end plate 10 will slide on the fixed column 20 to ensure the stability of the lifting plate 9. The lifting plate 9 pushes the trough plate 3 to rise and fall, thereby finally realizing the height adjustment of the slag hopper 4. In this way, the tilting height of the slag hopper 4 is adjusted.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
