Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a sintered ore halide liquid spraying mechanism. Background Art

[0002] Sintered ore is the raw material for blast furnace steelmaking. It generally contains a certain amount of ferric oxide and calcium silicate and other minerals. When the sintered ore enters the blast furnace and is heated to a low temperature range of 500℃-700℃, the volume expansion or crystal transformation of the mineralization will occur. In particular, the volume expansion of ferric oxide in vanadium-titanium sintered ore is large within the above temperature range, resulting in serious low-temperature reduction and pulverization of the sintered ore, which ultimately affects the stable operation of the blast furnace. In order to avoid these situations, it is necessary to spray halide liquid on the surface of the sintered ore to slow down the phenomenon of low-temperature reduction and pulverization of the sintered ore. When the halide liquid is spraying, a spray mechanism is generally provided on the conveying device of the sintered ore. When the sintered ore is being conveyed, the sprayed halide liquid will be sprayed onto the conveyed sintered ore. The spray mechanism is generally equipped with a box for containing the halide liquid. The halide liquid in the box is pumped to the spray pipe through a pipeline for spraying. However, the halide liquid in the box decreases with continuous use. At this time, the staff is required to conduct irregular inspections to replenish the halide liquid in the box. Once the staff fails to check in time, the halide liquid cannot be sprayed onto the sintered ore, which brings great inconvenience to the spraying work. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0016] like Figure 1-2 As shown, a sintered ore halide liquid spraying mechanism described in this embodiment comprises a first conveyor 1 and a second conveyor 2, the sintered ore on the first conveyor 2 falls onto the second conveyor 2, a first spray box 3 is arranged above the two conveyors, a first spray head 4 is arranged at the lower end of the first spray box 3, a second spray box 5 is also arranged between the two conveyors, a second spray head 6 is arranged on the second spray box 5 on the side facing the sintered ore falling, the first spray box 3 and the second spray box 5 are both connected to a liquid supply water tank 7 through a pipeline, the liquid supply water tank 7 is connected to a brine tank 9 through a liquid supply pipe 8, a liquid replenishing pump 10 and a solenoid valve 11 are arranged on the liquid supply pipe 8, and a liquid level monitoring device is arranged on the liquid supply water tank 7;

[0017] The second spray box 5 can spray the halogenated liquid on the sintered ore during its falling process, so that the surface of the sintered ore can be sprayed more evenly.

[0018] The liquid level monitoring equipment includes a floating rod 12 which can rise and fall with the liquid level in the liquid supply tank 7. A sensing head 13 is provided at one end of the floating rod 12 extending outside the liquid supply tank 7. A mounting frame 14 is provided on the top of the liquid supply tank 7. A first proximity switch 15 and a second proximity switch 16 are provided at the upper and lower ends of the mounting frame 14, respectively. The sensing head 13 and the first proximity switch 15 cooperate to control the liquid replenishment pump 10 and the solenoid valve 11 to suspend operation, and the sensing head 13 and the second proximity switch 16 cooperate to control the liquid replenishment pump 10 and the solenoid valve 11 to start operation.

[0019] A floating block 17 is arranged at one end of the floating rod 12 located in the liquid supply water tank 7, and a through hole is arranged on the top of the liquid supply water tank 7 for the floating rod 12 to pass through, and the floating rod 12 passes through the through hole.

[0020] The mounting frame 14 is provided with mounting holes, and both proximity switches are fixed to the mounting frame 14 via locking nuts.

[0021] The pipeline includes a delivery main pipe 18 connected to the liquid supply water tank 7. The delivery main pipe 18 is provided with a branch joint 19. The branch joint 19 is provided with a shunt pipe 20. The shunt pipe 20 is connected to the first spray box 3 and the second spray box 5 respectively.

[0022] The delivery main pipe 18 is provided with a liquid delivery pump 21 .

[0023] The first conveyor 1 and the second conveyor 2 are both assembled from a frame, support legs and a conveyor belt, wherein the height of the support legs on the first conveyor 1 is greater than the height of the support legs on the second conveyor 2. This arrangement creates a height difference between the first conveyor 1 and the second conveyor 2, facilitating the falling of the sintered ore.

[0024] The working principle of the utility model is as follows: the sintered ore is first transported on the first conveyor 1, and falls from the first conveyor 1 to the second conveyor 2. During the transportation process, the liquid delivery pump 21 will transport the halide liquid in the liquid supply water tank 7 along the pipeline to the first spray box 3 and the second spray box 5, and finally spray it out through the first spray head 4 and the second spray head 5. The halide liquid is sprayed onto the surface of the sintered ore. As the spraying work continues, the halide liquid level in the liquid supply water tank 7 will continue to decrease. At the same time, the floating block 17 in the liquid supply water tank 7 will move down with the halide liquid level, and the floating rod 12 will also sink accordingly, and then the induction head 13 on the top of the floating rod 12 will move down. When the halide liquid is about to run out, the induction head 13 comes into contact with the second proximity switch 16 at the lower end, thereby triggering the first The second proximity switch 16 sends a signal and controls the opening of the replenishing pump 10 and the solenoid valve 11 on the liquid supply pipe 8. At this time, the halogenated liquid stored in the brine tank 9 is supplied to the liquid supply water tank 7 through the liquid supply pipe 8. With the continuous delivery of the halogenated liquid, the halogenated liquid level in the liquid supply water tank 7 also rises, and then the float 17, the floating rod 12 and the sensor head 13 rise together. When the sensor head 13 contacts the first proximity switch 15 at the upper end, it means that the halogenated liquid in the liquid supply water tank 7 has been replenished. At this time, the first proximity switch 15 will send a signal and control the liquid replenishing pump 10 and the solenoid valve 11 to close, thereby stopping the replenishing work. In this way, the automatic replenishment of the halogenated liquid in the liquid supply water tank 7 can be realized, which reduces the workload of the staff and brings great convenience to the spraying work of the halogenated liquid.
