Description

Technical Field

[0001] The utility model relates to the technical field of metal production and processing, in particular to a circulating water cooling device. Background Art

[0002] In the process of metal production and smelting, cooling of metal is an important link. Existing cooling methods include using water to lower the temperature of the metal, that is, by spraying cooling water to absorb the heat of the metal and lower the temperature of the metal, but the sprayed cooling water is not effectively recycled, resulting in the loss and waste of cooling water.

[0003] In addition, metal smelting processing usually requires a large amount of water to cool the smelting equipment and smelting products, which will consume a lot of water resources. In some areas or seasons with scarce precipitation, water resources are limited, which will increase water resource consumption and operating costs. Therefore, it is necessary to consider the sustainable use and conservation of cooling water. Utility Model Content

[0012] In one embodiment of the present application, water retaining plates are provided on both end surfaces of the operating table.

[0013] In one embodiment of the present application, a plurality of support columns are connected to the bottom surface of the operating table.

[0014] The beneficial effects of the present application are: cooling water is sprayed out through the spray pipe connected to the first water tank through the nozzle, and starts to cool down after contacting the high-temperature metal placed on the operating table. The high-temperature cooling water after contacting the high-temperature metal flows into the drainage grooves on both sides of the operating table, and the cooling water flows into the drainage cavity through the drainage grooves, and then enters the water collecting tank through the drainage pipe under the drainage cavity.

By filtering and precipitating the cooling water, some metal substances that may be contained in the cooling water can be reduced. The discharge of these metal substances can be reduced through recycling, which is beneficial to environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] This embodiment provides a circulating water cooling device, such as Figure 1-Figure 5As shown, it includes an operating table 1, a support ring 2 is connected to the side of the operating table 1, a first water tank 21 is arranged on the upper end surface of the support ring 2, a drainage groove 11 is arranged on the side of the operating table 1, a drainage cavity 12 is connected to the lower part of the drainage groove 11, a drainage pipe 13 is connected to the lower end surface of the drainage cavity 12, the drainage cavity 12 is connected to the water collecting tank 3 through the drainage pipe 13, the water collecting tank 3 is connected to the cooling box 4 through the water guide pipe 31, a water pump 311 is installed on the water guide pipe 31, the cooling box 4 is connected to the first water tank 21 through the return pipe 41, the lower end of the first water tank 21 is connected to the water spray pipe 211, and the water spray pipe 211 is connected to the nozzle 212.

[0026] The operating table 1 is connected to a support ring 2 on the side, and a first water tank 21 is arranged on the upper end surface of the support ring 2. A water spray pipe 211 is connected to the lower end of the first water tank 21, and the water spray pipe 211 is connected to a nozzle 212. Cooling water is sprayed out through the water spray pipe 211 connected to the first water tank 21 through the nozzle 212. After the cooling water contacts the high-temperature metal placed on the operating table 1, heat transfer occurs, causing the high-temperature metal to begin to cool down, or part of the cooling water is heated and vaporized to absorb heat, causing the metal to cool down. A drainage groove 11 is arranged on the side of the operating table 1, and a drainage cavity 12 is connected to the lower part of the drainage groove 11. A drainage pipe 13 is connected to the lower end surface of the drainage cavity 12. The drainage cavity 12 is connected to the water collecting tank 3 through the drainage pipe 13, and is connected to the high-temperature metal. After contact, the high-temperature cooling water with increased temperature flows into the drainage grooves 11 on both sides of the operating table 1, and the cooling water flows into the drainage cavity 12 through the drainage grooves 11, and then enters the water collecting tank 3 through the drainage pipe 13 under the drainage cavity 12. The cooling water can be initially precipitated in the water collecting tank 3. The water collecting tank 3 is connected with the cooling box 4 through the water pipe 31. A water pump 311 is installed on the water pipe 31. The water pump 311 pumps the high-temperature cooling water into the cooling box 4 through the water pipe 31. After the high-temperature cooling water is cooled by the cooling box 4, the cooling water with reduced temperature flows into the first water tank 21 through the return pipe 41, thereby realizing the recycling of cooling water. The recycling of cooling water can reduce operating costs. The operating cost of the cooling system can be reduced by reducing the demand for fresh water replenishment, saving energy and reducing the waste of water resources. In addition, since the cooling water needs to come into contact with the metal, suspended matter or metal particles may be mixed in the cooling water. The preliminary precipitation treatment of the cooling water by the water collecting tank 3 can reduce the metal particles that may be contained in the cooling water, that is, the emission of these metal substances can be reduced, which is beneficial to environmental protection.

[0027] In one embodiment of the present application, Figure 5 As shown, a water outlet hole 213 is opened on the side of the first water tank 21 , and a side groove 121 is provided on the side of the drainage cavity 12 . The side groove 121 is connected to the drainage cavity 12 .

[0028] When the cooling water contacts the high-temperature metal, it will be heated and vaporized, and part of the cooling water will be lost in the form of vaporization. A water outlet 213 is provided on the side of the first water tank 21, and the cooling water can flow out from the water outlet, flow through the side of the support ring 2, and exchange heat with the support ring 2 to cool the support ring 2. The water vapor that is heated and vaporized encounters the support ring 2 with a relatively low temperature, releases heat and liquefies. The liquefied steam water flows down along the side wall of the support ring 2 to the drainage groove 11, which is beneficial to improving the recovery efficiency of the cooling water. A side groove 121 is provided on the side of the drainage chamber 12, and the side groove 121 is connected to the drainage chamber 12. The cooling water left along the outer wall of the support ring 2 will flow into the drainage chamber 12 through the side groove 121.

[0029] In one embodiment of the present application, Figure 3 As shown, a filter screen 111 is provided at the water inlet of the drainage trough 11 .

[0030] There will be some impurities on the surface of high-temperature metal. A filter screen 111 is provided at the water inlet of the drainage trough 11 to filter out some large particles or flocs mixed in after the cooling water contacts the high-temperature metal. On the one hand, it is beneficial to improve the purity of the cooling water. On the other hand, it prevents large impurities from flowing into the drainage cavity 12 with the cooling water and causing blockage, which is beneficial to improve the patency of the drainage cavity 12.

[0031] In one embodiment of the present application, Figure 5 As shown, a groove 32 is formed at the bottom of the water collecting box 3 .

[0032] After the cooling water enters the water collecting tank 3, some solid impurities in the cooling water settle to the bottom of the water collecting tank 3 due to gravity. A groove 32 is provided at the bottom of the water collecting tank 3 to guide the precipitated solid matter to a specific position for subsequent collection and processing, thereby stabilizing the solid matter precipitated at the bottom of the water collecting tank 3.

[0033] In one embodiment of the present application, Figure 5 As shown, a cooling chamber 42 is provided in the cooling box 4, and the cooling chamber 42 is used to fill the coolant. A spiral cooling pipe 43 is provided in the cooling chamber 42, and one end of the spiral cooling pipe 43 is connected to the water pipe 31, and the other end of the spiral cooling pipe 43 is connected to the return pipe 41.

[0034] One end of the spiral cooling tube 43 is connected to the water pipe 31, and the other end of the spiral cooling tube 43 is connected to the return pipe 41. The cooling chamber 42 is filled with coolant. The cooling water flows into the spiral cooling tube 43 in the cooling chamber 42 through the water pipe 31. The spiral cooling tube 43 and the coolant in the cooling chamber 42 undergo heat exchange and cooling. The cooled cooling water flows back to the first water tank 21 through the return pipe 41.

[0035] In one embodiment of the present application, Figure 1 and Figure 5 As shown, a water pipe 44 is connected to the side of the cooling box 4.

[0036] The coolant in the cooling chamber 42 can be replaced through the water pipe 44. Preferably, a valve is installed on the water pipe 44 to control the opening and closing of the water pipe 44. In addition, the coolant in the cooling chamber 42 is purer because it does not come into contact with hot metal and can be used as a hot water resource for reuse.

[0037] In one embodiment of the present application, Figure 3 As shown, water retaining plates 14 are provided on both end surfaces of the operating platform 1 .

[0038] Prevent high-temperature cooling water from flowing out from both end surfaces of the operating table 1 after contacting hot metal and scalding the staff.

[0039] In one embodiment of the present application, Figure 1 As shown, a plurality of support columns 15 are connected to the bottom surface of the operating platform 1 .

[0040] Generally, metal materials are heavy and the pressure on the operating table 1 is relatively large. Connecting a plurality of support columns 15 to the bottom surface of the operating table 1 is beneficial to keeping the operating table 1 stable and improving the stability of the operating table 1 .

[0041] During the actual use of this application: the metal material that needs to be cooled is transferred to the surface of the operating table 1, the lower end of the first water tank 21 is connected to a water spray pipe 211, and the water spray pipe 211 is connected to the nozzle 212. The cooling water is sprayed out through the water spray pipe 211 connected to the first water tank 21 through the nozzle 212. After the cooling water contacts the high-temperature metal placed on the operating table 1, heat transfer occurs, causing the high-temperature metal to begin to cool down. A drainage groove 11 is provided on the side of the operating table 1, and the lower part of the drainage groove 11 is connected to a drainage cavity 12. The lower end surface of the drainage cavity 12 is connected to a drainage pipe 13, and the drainage cavity 12 is connected to the water collecting tank 3 through the drainage pipe 13. The high-temperature cooling water whose temperature rises after contacting the high-temperature metal flows into the drainage grooves 11 on both sides of the operating table 1, and the cooling water flows through the drainage grooves 11 flows into the drainage chamber 12, and then enters the water collection tank 3 through the drainage pipe 13 below the drainage chamber 12. The cooling water can be initially precipitated in the water collection tank 3. The water collection tank 3 is connected to the cooling box 4 through the water pipe 31. The water pump 311 is installed on the water pipe 31. The water pump 311 pumps the high-temperature cooling water into the cooling box 4 through the water pipe 31. The water pump 311 also pressurizes the cooling water in the water pipe 31, so that the cooling water flows through the cooling box 4 and then flows back to the first water tank 21 through the return pipe 41. After the high-temperature cooling water is cooled by the cooling box 4, the cooling water with reduced temperature flows into the first water tank 21 through the return pipe 41, thereby realizing the recycling of cooling water. The recycling of cooling water can reduce operating costs. By reducing the demand for fresh water replenishment, saving energy and reducing the waste of water resources.
