The conduit 52 is interconnected with the collecting tank 50. The end of the conduit 52 away from the collecting tank 50 is penetrated and fixed with a water tank 53. The circulation component 5 also includes a filter 54. The water cooled by the blast furnace 1 flows into the opening of the collecting tank 50 and falls on the surface of the connecting plate 51. The connecting plate 51 is inclined, which makes the water flow to a lower place. At this time, the water flows into the conduit 52, and the water flows into the water tank 53 through the conduit 52.

[0022] The filter element 54 includes a long plate 540, which is fixed on the inner wall of the water tank 53. There are four long plates 540, and two of the four long plates 540 form a group, which are divided into two groups.

A second water pipe 543 is penetrated and fixed on the left side of the water tank 53, and a first water pipe 542 is penetrated and fixed on the right side of the water tank 53. A solenoid valve 544 is connected between the second water pipe 543 and the water tank 53. When water flows into the water tank 53, it is filtered by the filter plate 541 to prevent the water flow from driving the residue on the surface of the blast furnace 1 to block the single-fluid spray gun 63. At this time, it is extracted again through the integrated pump station 4, and then it can be used reciprocally to avoid waste of water resources.

[0023] The cooling assembly 6 includes a water rack 60, which is penetrated by the collecting tank 50 and is fixedly connected to the collecting tank 50. A fixing rack 62 is penetrated on the top of the water rack 60, and the fixing rack 62 is fixedly connected to the water rack 60. The fixing rack 62 and the water rack 60 are interconnected. A single-fluid spray gun 63 is penetrated on the side of the fixing rack 62 close to the blast furnace 1, and the single-fluid spray gun 63 is fixedly connected to the fixing rack 62. An L-shaped plate 64 is fixed on the side of the fixing rack 62 away from the single-fluid spray gun 63. An electric telescopic rod 65 is fixed on the bottom of the side of the L-shaped plate 64 away from the fixing rack 62. A cover 66 is fixed on the bottom of the output end of the electric telescopic rod 65.

At this time, the water source in the water tank 53 enters the water storage rack 60 and the fixed rack 62 through the integrated pump station 4 and the connecting pipe 61, and the electric telescopic rod 65 rises with the cover 66. At this time, the single-fluid spray gun 63 sprays water to cool the throat of the blast furnace 1;

[0024] The surface of the connecting plate 51 is set as an inclined surface to guide the water flow;

[0025] A PLC control cabinet 3 is placed on one side of the blast furnace 1, and an electrical cabinet 2 is placed next to the PLC control cabinet 3. The PLC control cabinet 3, the electrical cabinet 2, the electric telescopic rod 65, the solenoid valve 544, and the single-fluid spray gun 63 of the integrated pump station 4 are electrically connected to facilitate personnel control;

[0026] Eight groups of single-fluid spray guns 63 and fixing frames 62 are provided, and the eight groups of single-fluid spray guns 63 and fixing frames 62 are arranged in a circular array with the center of the water storage frame 60 as the axis, so that cooling can be performed in all directions.

At this time, the single-fluid spray gun 63 sprays water to cool the throat of the blast furnace 1. The outflowing water falls into the opening of the collecting tank 50 and falls onto the surface of the connecting plate 51. The connecting plate 51 is inclined, which will cause the water to flow to a lower place. The water flows into the conduit 52, and then into the water tank 53 through the conduit 52. The water is filtered by the filter plate 541 to prevent the water from driving the residue on the surface of the blast furnace 1 to block the single-fluid spray gun 63. At this time, it is extracted again through the integrated pump station 4, and then it can be used reciprocally to avoid waste of water resources. When cooling is not needed, the solenoid valve 544 and the integrated pump station 4 are closed through the electrical cabinet 2 and the PLC control cabinet 3, and the electric telescopic rod 65 is moved down at the same time, thereby driving the cover 66 to move down, so that the cover 66 blocks the single-fluid spray gun 63, thereby preventing dust from blocking the single-fluid spray gun 63.
