The end part of the first jet head 9 is provided with a second jet head 92, and the nozzle direction of the second jet head 92 points to the gaps between the two sides and the bottom surface of the steel strip to be cooled and the water leakage holes 11; the second jet head 92 is communicated with the inner cavity of the first jet head 9, and the gas injected into the inner cavity of the first jet head 9 by the second duct enters the inner cavity of the first jet head 9 firstly and then is ejected out through the nozzle; in order to prevent the water receiving plate 12 from obstructing the movement of the steel strip, gaps exist between the water receiving plate 12 and the bottom surface and between the two sides of the steel strip, and when the first air jet head 9 jets air, as the second air jet head 92 is communicated with the inner cavity of the first air jet head 9, the second air jet head 92 sprays air to be opposite to the liquid water flowing out of the gaps between the two sides and the bottom surface of the steel strip to be cooled and the water leakage holes 11, so that the liquid water flowing out of the gaps between the two sides and the bottom surface of the steel strip to be cooled and the water leakage holes 11 is prevented from flowing out and falling outside the water receiving space formed by the water receiving plate 12 and the cooling box 1 through the gaps between the water receiving plate 12 and the bottom surface and the two sides of the steel strip.
During operation, a worker guides the steel strip to be cooled to be inserted into the water leakage hole 11 formed in the cooling box 1, then supports the steel strip through the support piece 2 in the cooling box 1, and finally completely penetrates through the cooling box 1, at the moment, the first water pump 14 is started, liquid water exists in the cooling box 1 at the beginning, and the water level of the liquid water is higher than that of the water leakage hole 11, so that the liquid water in the cooling box 1 leaks into a water receiving space formed by the water receiving plate 12 and the outer surface of the cooling box 1 through a gap between the water leakage hole 11 and the steel strip to be cooled; meanwhile, the first water pump 14 pumps out the liquid water in the water receiving space into the excessive water tank 15 through the first water pipe 13, and then the liquid water is injected into the cooling box 1 through the second water pipe 16, so that the liquid water in the cooling box 1 keeps the liquid level higher than the water leakage holes 11 continuously, and the steel belt penetrating through the cooling box 1 through the water leakage holes 11 is completely covered by the liquid water; the inner diameter size of the water leakage holes 11 can be adjusted by adjusting the number of the filling frames 3 inserted into the water leakage holes 11 in the water leakage holes 11 for steel belts with different sizes, so that the cooling of the steel belts with various sizes is facilitated; when the inner diameter of the water leakage hole 11 is adjusted through the filling frame 3, the filling frame 3 needs to be drawn out or inserted into the water leakage hole 11, so that the handle 31 is arranged, and a worker pulls the filling frame 3 through the handle 31, so that the operation of the worker is facilitated.
Wherein when the steel strip passes through the cooling box 1 and is subjected to cooling zone, the steel strip continuously moves, deviation possibly occurs in the moving process, and therefore, the pressing rollers 4 are arranged, and two sides of the steel strip positioned in the cooling box 1 are limited by the pressing rollers 4, so that the steel strip is limited in position when moving; for steel belts with different sizes, the sliding plate 43 at the bottom end of the support plate 41 is controlled to move in the sliding groove 5 through the telescopic rod 42, so that the pressing roller 4 is driven to synchronously move, and the pressing roller 4 can press and limit the steel belts with different sizes; when the steel strip is cooled, the second water pump in the circulating water tank 6 at one side of the cooling tank 1 is started, so that the circulating water tank 6 injects low-temperature liquid water into the cooling tank 1 through the third water pipe 61, meanwhile, the second water pump in the circulating water tank 6 at the other side of the cooling tank 1 is started, the liquid water in the cooling tank 1 is pumped into the circulating water tank 6 through the third water pipe 61, and the liquid water speeds of the circulating water tanks 6 at the two sides are the same, so that the total amount of the liquid water in the cooling tank 1 cannot be changed due to the process, and the temperature of the liquid water in the cooling tank 1 is regulated and controlled not to continuously rise due to the cooling of the steel strip because the low-temperature liquid water is continuously injected into the cooling tank 1, the cooling effect on the steel strip is continuously maintained by the cooling tank 1, and the liquid water is not required to be periodically replaced by staff, thereby being beneficial to keeping the cooling continuity of the steel strip; when the steel strip is cooled, evaporation of liquid water in the cooling tank 1 occurs, so that the overall liquid water in the cooling tank 1 is reduced, the cooling speed of the steel strip is affected when the cooling speed is reduced to a certain degree, the cooling tank is supplemented by staff, the staff is difficult to observe the change of the amount of the liquid water in the cooling tank 1 through naked eyes, a floating block 71 is arranged, the floating block 71 is positioned in the cooling tank 1 and is limited in a limiting sleeve 7, a gap is formed in the surface of the limiting sleeve 7, the floating block 71 is contacted with the liquid water, the floating block is upwards floated under the action of buoyancy, the floating block 71 gradually moves downwards along with the reduction of the liquid water, and the staff judges the liquid level of the liquid water by observing the scale on the surface of the floating block 71 and the alignment numerical value of the limiting sleeve 7, so as to judge whether the liquid water needs to be added.
The first air pump is started during cooling, the water mist generated during cooling of the steel strip is pumped in through the pumping port of the air pumping head 8, and the water mist is pumped into a designated area through the air pumping head 8 and the first guide pipe, so that the influence of water mist dissipation on the air quality of a working space is reduced; when the steel strip is cooled, a second air pump is started, the second air pump injects air into the inner cavity of the first jet head 9 through a second guide pipe, and then the air is sprayed out through a nozzle, the nozzle of the first jet head 9 is obliquely directed to the top surface of the steel strip to be cooled and is opposite to the liquid water flowing out between the top surface of the steel strip and the water leakage hole 11, so that the liquid water flowing out between the top surface of the steel strip and the water leakage hole 11 is prevented from continuously flowing on the top surface of the steel strip and separating from a water receiving space formed between the water receiving plate 12 and the outer surface of the cooling box 1; the consumption of liquid water in the cooling box 1 is reduced; in order to prevent the water receiving plate 12 from obstructing the movement of the steel strip, gaps exist between the water receiving plate 12 and the bottom surface of the steel strip and between the two sides, and when the first air jet head 9 jets air, the second air jet head 92 is communicated with the inner cavity of the first air jet head 9, so that the second air jet head 92 jets air to be opposite to the liquid water flowing out from the gaps between the two sides of the steel strip to be cooled and the bottom surface and the water leakage holes 11, and the liquid water flowing out from the gaps between the two sides of the steel strip to be cooled and the bottom surface of the steel strip and the two sides is prevented from flowing out and falling out of the water receiving space formed by the water receiving plate 12 and the cooling box 1 through the gaps between the water receiving plate 12 and the bottom surface of the steel strip and the two sides.
