[0002] Cast copper usually refers to a copper alloy containing zinc, which is similar to brass but has different physical and chemical properties. Cast copper is made by mixing copper and zinc in a certain proportion and then casting it into various objects or works of art. The cast copper parts need to be cooled during the processing.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The present invention proposes a rapid cooling mechanism for copper casting, comprising a cooling chamber 1, a first cooling water storage tank 2 and a second cooling water storage tank 3. The inner cavity of the cooling chamber 1 is divided into a first cooling chamber, a second cooling chamber and a third cooling chamber. A support mesh plate 11 is fixedly connected to the bottom end of the inner cavity of the cooling chamber 1, and the support mesh plate 11 supports the upper straight section of the conveyor belt of the copper casting. The top of the inner cavity of the first cooling chamber is connected to a spray pipe 8 through a hydraulic telescopic rod 6, and a collection box 9 is placed at the bottom of the inner cavity of the first cooling chamber. The support mesh plate 11 is located between the collection box 9 and the spray pipe 8. A steam exhauster 7, a water pump 14 and a first refrigerator 19 are provided outside the first cooling chamber. The air inlet end of the steam exhauster 7 extends to the inner cavity of the first cooling chamber through a pipeline. The air outlet end of the steam exhauster 7 and the water outlet end of the collection box 9 are both connected through the first refrigerator 19 and the return water end of the first cooling water storage tank 2. The first refrigerator 19 can cool down the steam and the heated cooling water. The cooled cooling water flows back to the first cooling water storage tank 2 for storage. The first cooling water storage tank 2 is connected to the spray pipe 8 through a water pump 14. The water pump 14 can pump the water in the first cooling water storage tank 2 into the spray pipe 8. The cooling water in the inner cavity of the spray pipe 8 is sprayed onto the copper casting through the water spray holes of the spray pipe 8 to cool down the copper casting. The heated water passes through the copper casting conveyor belt and the supporting mesh and falls into the collecting box 9.

[0027] A spray pipe 20 and an air jet pipe 10 are alternately arranged at the top of the inner cavity of the second cooling chamber, and a collecting box 21 is arranged at the bottom of the inner cavity of the second cooling chamber. The spray pipe 20 and the air jet pipe 10 are respectively fixedly connected to the cooling chamber 1 through another hydraulic telescopic rod 6. A water pump 2 15, a blower 16 and a second refrigerator 22 are arranged on the outside of the second cooling chamber. The spray pipe 20 in the second cooling chamber is connected to the first cooling water storage tank 2 through the water pump 15. The water pump 15 pumps the water in the first cooling water storage tank 2 into the inner cavity of the spray pipe 20. The air jet pipe 10 in the second cooling chamber is connected to the air outlet end of the blower 16. The air inlet end of the blower 16, the exhaust end of the second cooling chamber and the water outlet end of the collecting box 21 are all connected to the first cooling water storage tank 2 through the second refrigerator 22. The second refrigerator 22 can cool the heated air, the heated cooling water and the air to be pumped into the air jet pipe 10. The second cooling chamber uses spraying and air jetting to cool the copper castings, and the air can dry the water adhering to the surface of the copper castings, making it easier for the cooling water to cool the copper castings again.

[0028] When the cooling mechanism is actually used, multiple groups of spray pipes 20 and air jet pipes 10 can be provided, which can be arranged according to needs, and are not limited here, so as to improve the cooling speed of the copper casting.

An air inlet 26 is provided on one side of the bottom of the inner cavity of the dehumidifier box 13, and a drain port 12 is provided on the other side of the bottom of the inner cavity of the dehumidifier box 13. The two groups of squeezing water structures are located between the air inlet 26 and the drain port 12. Exhaust holes are evenly provided on the side wall of the dehumidifier box 13 near the drain port 12. The squeezing water structure includes a hydraulic telescopic rod 23 fixedly connected to the dehumidifier box 13, an extrusion block 27 fixedly connected to the end of the output shaft of the hydraulic telescopic rod 23, and a water-absorbing sponge 25 released from the extrusion block 27. Two groups of limiting plates 28 are fixedly connected in the inner cavity of the dehumidifier box 13. The water-absorbing sponge 25 is located in the middle of the inner cavity of one group of limiting plates 28. The extrusion block 27 is movably connected to the inner cavity of one group of limiting plates 28. A flow channel is provided at the bottom of the two groups of limiting plates 28. One end of the flow channel is located at the bottom of the inner cavity of the limiting plate 28, and the other end of the flow channel extends to the inner cavity of the drain port 12. By setting the dehumidification box 13, the water-absorbing sponge 25 can dehumidify the air exhausted from the third cooling chamber, and the hydraulic telescopic rod 23 drives the squeezing block 27 to squeeze out the water absorbed in the water-absorbing sponge 25, and the squeezed water is retained in the drain port 12 through the flow channel, thereby reducing the loss of cooling water.

[0031] The bottoms of the spray pipe 1 8, the spray pipe 2 20 and the air jet pipe 10 are at the same height, and one end of the spray pipe 1 8 and the other end of the spray pipe 2 20 are fixedly connected to the water inlet pipe 4, and the other end of the water inlet pipe 4 is connected to the water outlet end of the water pump 14 or the water outlet end of the water pump 2 15. The top of the air jet pipe 10 is fixedly connected to the air inlet pipe 5, and the other end of the air inlet pipe 5 is connected to the air outlet end of the blower 16 or the air outlet end of the blower 2 17. The air inlet pipe 5 and the water inlet pipe 4 are both telescopic pipes, and the material thereof can be a corrugated pipe.

[0032] The temperature of the water in the second cooling water storage tank 3 is lower than that of the water in the first cooling water storage tank 2. The temperature of the water in the second cooling water storage tank 3 is room temperature. With this arrangement, the temperature of the cooled copper casting can be kept at room temperature, thereby avoiding condensation when the copper casting comes into contact with the outside air.

[0033] The air sprayed out from the air spray pipe 10 in the third cooling chamber is at room temperature, and the air spray pipe 10 is located on the side of the spray pipe 2 20 away from the spray pipe 1 8 .

[0034] The outer surface of the first cooling water storage tank 2 is wrapped with a heat-insulating pad, which can be made of pearl cotton to reduce the impact of the external environment on the cooling water temperature. The outer surface of the second cooling water storage tank 3 is wrapped with a heat-conducting pad, which can be made of heat-conducting silica gel, so that the cooling water temperature in the second cooling water storage tank 3 can be kept consistent with normal temperature, which is convenient for use.

Through these personnel, all electrical components in this application are connected to their compatible power supplies through wires, and according to actual conditions, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order between each electrical component, and the detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0036] In summary, when used in this application, a segmented cooling method is adopted to improve the cooling efficiency of the copper casting and avoid the generation of cold dew when the cooled copper casting contacts the outside air; spraying and air blowing are adopted. By combining water cooling and air cooling, the cooling water adhering to the surface of the copper casting is blown dry, which facilitates the contact between the cooling water and the surface of the copper casting, improves the cooling efficiency of the copper casting, and cools the return water of the copper casting at different cooling stages in batches, increases the speed at which the heated water participates in the cycle, and thus reduces the amount of circulating cooling water.
