DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in further detail below in combination with the drawings. Only this statement, the up, down, left, right, front, back, inside, outside and other directions of the utility model appearing or about to appear in the text, only with the drawings of the utility model as the benchmark, it is not the specific limitation of the utility model.

[0021] Embodiment: a kind of oxygen-enriched side-blown furnace copper water jacket cooling device, as shown in Figure Figures 1-4 , including water storage tank 1, water pump 2, copper water jacket 3, cooling pipeline 4, cooling tank 5, chute 6, cooling plate 7, condensing plate 10, scraping assembly and filter plate 12, copper water jacket 3 is contacted with furnace wall, cooling tank 5 is installed at the top of water storage tank 1, cooling tank 5 is communicated with water storage tank 1, water pump 2 is installed outside water storage tank 1, the lower end of cooling pipeline 4 is communicated with water storage tank 1, cooling pipeline 4 is bent and arranged in copper water jacket 3 after water pump 2, increase contact area, the upper end of cooling pipeline 4 is communicated with cooling tank 5, and cooling pipeline 4 upper end is provided with filter plate 12, filter plate 12 is located on the inner wall of cooling tank 5, four pieces of chute 6 are connected in cooling tank 5, and each two pieces of chute 6 are slidably connected with a piece of cooling plate 7, cooling plate 7 is only contacted with one side of cooling tank 5, the inclination directions of two pieces of cooling plate 7 are different, condensing plate 10 is connected at the top of cooling tank 5, and scraping assembly for accelerating the drop of cooling liquid is arranged in cooling tank 5.

[0022] As shown in Figure Figure 3 and Figure 4 , scraping assembly includes support frame 8, cylinder 9 and scraper 11, support frame 8 is connected at the top of water storage tank 1, support frame 8 is connected with the bottom of cooling tank 5, cylinder 9 is installed on support frame 8, the piston rod of cylinder 9 is connected with scraper 11, scraper 11 is located in cooling tank 5, and scraper 11 is slidably connected with the bottom surface of cooling plate 7.

[0023] During smelting, the copper jacket 3 is wrapped by high temperature, and the water pump 2 is turned on to draw the cooling liquid from the water storage tank 1 through the cooling pipeline 4. The cooling liquid is usually clean water, and the cooling liquid obtains kinetic energy through the water pump 2 and moves upward along the cooling pipeline 4. When passing through the copper jacket 3, there is a temperature difference between the cooling liquid and the copper jacket 3, heat transfer occurs, the copper jacket 3 absorbs heat, and the cooling liquid is cooled. After the cooling liquid with a higher temperature passes through the filter plate 12, it enters the cooling tank 5. The water vapor formed after part of the cooling liquid is gasified contacts the condensing plate 10. The condensing plate 10 absorbs the heat of the water vapor to liquefy it, and the liquefied cooling liquid is suspended on the condensing plate 10 and falls down after gathering. Most of the cooling liquid falls on the cooling plate 7 after entering the cooling tank 5. There is a gap between the cooling plate 7 and the inner wall of the cooling tank 5. The cooling plates 7 with different inclined directions slow down the falling speed of the cooling liquid, thereby prolonging the heat dissipation time. The cooling liquid enters the water storage tank 1 after passing through the multiple cooling plates 7, realizing the circulation of the cooling liquid.

[0024] At the same time, the air cylinder 9 is turned on to drive the scraper 11 to move back and forth, timely scraping off the liquefied cooling liquid on the condensing plate 10, improving the utilization efficiency of the condensing plate 10, and relying on the air and the cooling tank 5 to naturally cool the cooling liquid. The temperature of the cooling liquid will not be too low, thereby maintaining the temperature of the copper jacket 3 and reducing the excessive absorption of the heat of the smelting furnace and the heat loss.

[0025] As shown in Figure 1 , it further comprises an observation window 13. The observation window 13 made of transparent material is arranged on the top of the front side of the cooling tank 5.

[0026] The observation window 13 arranged on the cooling tank 5 is convenient for observing the situation in the cooling tank 5.

[0027] As shown in Figure 1 and Figure 4 , it further comprises a feeding hopper 14. The feeding hopper 14 is arranged on the water storage tank 1.

[0028] When it is necessary to add cooling liquid, the cover plate of the feeding hopper 14 is opened, the capacity of the cooling liquid in the water storage tank 1 is checked, and then the cooling liquid is supplemented through the feeding hopper 14 or other solvents are added to assist the work of the cooling liquid.

[0029] As shown in Figure 1 , it further comprises a thermometer 15. The thermometer 15 is installed on the front side of the cooling tank 5, and the detection area of the thermometer 15 is located on the top of the cooling tank 5.

[0030] The thermometer 15 is used to display the temperature in the cooling tank 5, which is convenient for the staff to monitor the temperature of the cooling liquid and make corresponding adjustments. By adjusting the scraping speed of the scraper 11 driven by the air cylinder 9, the frequency of removing the liquefied cooling liquid on the condensing plate 10 can be changed, thereby indirectly regulating the temperature of the cooling liquid.

[0031] As shown in Figure 1As shown, the cooling device further comprises a detachable baffle 16, which is connected to the front side of the cooling box 5.

[0032] When the temperature is low, the cooling plates 7 can be taken out by opening the detachable baffle 16, so that the cooling liquid directly falls into the water storage tank 1, thereby reducing unnecessary heat loss.

[0033] The oxygen-enriched side-blown furnace copper jacket 3 cooling device extracts the cooling liquid from the water storage tank 1 through the water pump 2, and the cooling liquid enters the copper jacket 3 along the cooling pipeline 4 to cool and absorb the heat of the copper jacket 3, so that the temperature rises. After being cooled, the cooling liquid enters the cooling box 5 through the filter plate 12, and part of the cooling liquid is gasified and contacts the condensing plate 10. The condensing plate 10 releases heat and liquefies after being heated, and is suspended on the condensing plate 10. Most of the cooling liquid falls on the cooling plate 7, and the falling speed is slowed down by the multiple cooling plates 7, and the heat release time is prolonged. At the same time, the cylinder 9 pushes the scraper 11 to move back and forth, and the condensed liquid on the condensing plate 10 is scraped off, thereby improving the utilization efficiency of the condensing plate 10. After passing through the cooling plate 7, the cooling liquid finally falls into the water storage tank 1, realizing the circulation of the cooling liquid. The thermometer 15 monitors the temperature in the cooling box 5, and the workers can observe the cooling process through the observation window 13, and supplement the cooling liquid through the feeding hopper 14. When the temperature is low, the cooling plates 7 can be taken out by opening the detachable baffle 16, so that the cooling liquid directly falls into the water storage tank 1, thereby reducing heat loss.
