[0020] The spraying part comprises a buffer mechanism, a spraying mechanism and a lifting mechanism; the buffer mechanism is arranged on the flat plate 1; the spraying mechanism and the lifting mechanism are both arranged on the buffer mechanism, and the spraying mechanism is connected to the lifting mechanism.

[0021] The function of the buffer mechanism is to prevent the sintered ore from hard contact and collision with the spray mechanism. The buffer mechanism provides reaction time for the lifting mechanism to ensure that the spray mechanism can be pulled up in time; the buffer mechanism includes a touch pressure switch 3, a spring 4 and a slide plate 5; a square hole is provided on the plate 1, and the slide plate 5 is slidably arranged on the inner wall of the square hole; the touch pressure switch 3 is arranged on the inner wall of the square hole of the plate 1 near the end of the belt conveyor; one end of the spring 4 is connected to the slide plate 5, and the other end of the spring 4 is connected to the inner wall of the square hole of the plate 1 near the end of the belt conveyor; when the sintered ore hard contacts the spray mechanism, the slide plate 5 slides to trigger the signal of the touch pressure switch 3, and the signal indicates that the sintered ore hard contacts the spray mechanism. At this time, the lifting mechanism quickly raises the spray mechanism, thereby making the spray mechanism separate from the sintered ore, providing protection for the spray mechanism; the goods on the belt conveyor are transported from the head end to the end; the signal output end of the touch pressure switch 3 is connected to the signal input end of the CPU.

[0022] The spray mechanism includes a vertical column 6, a nozzle and an infrared rangefinder 7; the slide plate 5 is provided with a vertical through hole, and the vertical column 6 is inserted in the through hole of the slide plate 5; the nozzle is arranged at the bottom end of the end face of the vertical column 6 close to the end of the belt conveyor; the nozzle can spray cooling water onto the sintered ore; a pipe is buried in the vertical column 6, and the top of the pipe is connected to the water outlet at the top of the vertical column 6, the water outlet at the top of the vertical column 6 is connected to the water source through a long hose, and the bottom of the pipe is connected to the water inlet of the nozzle; the bottom end of the end face of the vertical column 6 close to the head end of the belt conveyor is connected to the water outlet at the top of the vertical column 6.

The lead screw nut 10 below is connected; the pull-wire distance sensor 11 can monitor the position of the lead screw nut in real time, and then know the relative position of the vertical column, and finally know the position of the bottom end of the vertical column and the nozzle; the height of the top of the sintered ore and the height of the bottom end of the vertical column are both known, so through dynamic adjustment, the vertical column is just higher than the top of the sintered ore; the lead screw nut 10 is connected to the top of the vertical column 6; the signal input end of the motor 9 is connected to the signal output end of the CPU; the signal output end of the pull-wire distance sensor 11 is connected to the signal input end of the CPU.

[0024] The wind wall part includes a wind knife 12 and a connecting plate 13; the connecting plate 13 is arranged on the side wall of the flat plate 1, and the connecting line between the connecting plates 13 on both sides is parallel to the length direction line of the belt; the wind knife 12 is arranged on the bottom end surface of the connecting plate 13; the wind knife 12 is connected to the high-pressure air source through a connecting pipe; the airflow blown out by the wind knife, on the one hand, blows and cools the sintered ore, and on the other hand, creates a wind wall to isolate the mist of the cooling water and prevent the cooling water from diffusing out of the belt conveyor.

[0025] The model of the CPU module in the utility model is 87C196KC.

[0026] Actual use process: the belt transports the sintered ore forward, passing through the front wind knife, infrared rangefinder 7, nozzle and rear wind knife in turn; the wind knives on both sides and the diffusion of cooling water at the vertical plates on both sides provide shielding; when the sintered ore passes the infrared rangefinder 7, the highest point of the sintered ore can be roughly known, and then the motor 9 is started to control the vertical column 6 to adjust the position vertically, so that the bottom end of the vertical column 6 is just higher than the top of the sintered ore, so that the nozzle can be as close to the sintered ore as possible, reducing the diffusion of cooling water; once the sintered ore hard contacts and hits the vertical column 6, the vertical column 6 moves laterally with the slide plate 5 under the push of the sintered ore, thereby triggering the signal of the touch pressure switch, and then the motor 9 quickly acts to drive the vertical column 6 upward to separate from the sintered ore. After separating from the sintered ore, the signal of the touch pressure switch disappears, and then the motor 9 drives the vertical column 6 downward to restore the normal operating state, and keep the vertical column at a reasonable distance from the top of the sintered ore.
