Description

Technical Field

[0001] This utility model relates to the field of beryllium copper alloy casting cooling, and in particular to a circulating water cooling device for beryllium copper alloy casting cooling. Background Technology

[0002] Beryllium copper alloy castings are material castings with high strength, high elasticity, excellent electrical conductivity and corrosion resistance. During the production process, they need to be cooled quickly and evenly to ensure the stability of their mechanical properties and dimensions. Therefore, the core cooling device required is a circulating water cooling device. The circulating water cooling device achieves efficient cooling of beryllium copper castings through a closed-loop process of "heat absorption-heat dissipation-circulation".

[0003] Chinese patent document CN212692539U discloses a cooling device for beryllium copper alloy smelting. It includes a furnace body, a water tank installed on the outer wall of the furnace body, and a water pump connected to the inner wall of the water tank. One end of the water pump is connected to a water pump, and a drain pipe is provided on one side of the water pump. One end of the drain pipe is connected to a diversion pipe, and nozzles are connected to the surface of the diversion pipe. A water collection plate is provided on the surface of the furnace body. An air inlet pipe is connected to the inner wall of the furnace body, and a fixing block is connected to the inner wall of the air inlet pipe. Fixing bolts are connected to the inner wall of the fixing block, a dustproof net is connected to the inner wall of the fixing block, and an activated carbon net is connected to the inner wall of the fixing block. This cooling device for beryllium copper alloy smelting, through the diversion pipe, can be equipped with multiple nozzles for better cooling, thereby improving the cooling efficiency and increasing the service life of the device.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figures 1-6 As shown, a circulating water cooling device for cooling beryllium copper alloy castings includes a plate heat exchanger 1 and a cooling tank 8. The upper right side of the plate heat exchanger 1 is fixedly connected to a coolant tank 2. A through hole 3 is provided at the top left end of the coolant tank 2. A filter assembly 4 is provided at the upper inside of the coolant tank 2. A top plate 5 is provided inside the through hole 3. A fluororubber sealing ring 6 is fixedly connected to the lower outer side of the top plate 5. A contact cooling assembly 7 is provided at the right end of the coolant tank 2. The cooling tank 8 is provided to the right of the contact cooling assembly 7. A storage grid plate 9 is fixedly connected to the lower inner side of the cooling tank 8. A second variable frequency centrifugal pump 10 is fixedly connected to both the front and rear ends of the bottom right side of the coolant tank 2. A cooling pipe 11 is fixedly connected to the output port of the second variable frequency centrifugal pump 10. The bottom left side of the cooling pipe 11 is fixedly connected to a circulating water tank 12. The bottom left side of the circulating water tank 12 is fixedly connected to a third variable frequency centrifugal pump 13.

[0020] A coolant tank 2 is fixedly connected to the upper right side of the plate heat exchanger 1 by a pipe fitting. A connecting water pipe 71 is connected through the top right end of the coolant tank 2. The bottom left side of the connecting water pipe 71 is located at the bottom right side of the coolant tank 2. The upper left side of the connecting water pipe 71 is fixedly connected to the input and output ports of the first variable frequency centrifugal pump 72. The bottom right side of the connecting water pipe 71 is connected through the middle of the top of the cooling box 8. A mist spray head 73 is fixedly connected to the bottom right side of the connecting water pipe 71. The mist spray head 73 is located in the middle of the top inside the cooling box 8. A coolant tank 2 is fixedly connected to the upper right side of the plate heat exchanger 1 by a pipe fitting. A connecting water pipe 71 is connected through the top right end of the coolant tank 2. The bottom left side of the connecting water pipe 71 is located at the bottom right side of the coolant tank 2. The upper left side of the connecting water pipe 71 is fixedly connected to the input and output ports of the first variable frequency centrifugal pump 72. The bottom right side of the connecting water pipe 71 is connected through the middle of the top of the cooling box 8. A mist spray head 73 is fixedly connected to the bottom right side of the connecting water pipe 71. The mist spray head 73 is located in the middle of the top inside the cooling box 8. A feed inlet and lifting door are located on the upper right side of the cooling box 8. The beryllium copper alloy casting is moved through the feed inlet on the right side of the cooling box 8 onto the mist spray head 73 inside the cooling box 8. Different cooling methods are used depending on the performance of the beryllium copper alloy casting. One cooling method is spray cooling. The connecting water pipe 71 is an inverted "U" shaped rod. The left end of the connecting water pipe 71 is located in the coolant tank 2, and the right end of the connecting water pipe 71 is connected to the mist spray head 73 inside the cooling box 8. A variable frequency centrifugal pump 72 draws the coolant from the coolant tank 2 into the connecting water pipe 71. The coolant is then sprayed in an atomized state onto the beryllium copper alloy casting by a mist spray head 73, allowing the beryllium copper alloy to cool down gradually and better. The atomized coolant will not have any effect on the beryllium copper alloy casting. The sprayed coolant is collected from the holes on the storage grid plate 9 to the bottom of the cooling box 8, and then flows into the circulating water tank 12 through the pipe connecting the cooling box 8 and the circulating water tank 12. A storage grid plate 9 is fixedly connected to the lower inner side of the cooling tank 8. A second variable frequency centrifugal pump 10 is fixedly connected to the front and rear ends of the bottom right side of the coolant tank 2. The bottom of the first variable frequency centrifugal pump 72 and the second variable frequency centrifugal pump 10 are both fixedly connected to the right side of the coolant tank 2 by support plates. The second variable frequency centrifugal pump 10 is fixedly connected to the upper left inlet of the cooling pipe 11.

The bottom left side of the cooling pipe 11 is fixedly connected to the bottom right side of the circulating water tank 12. The bottom of the coolant tank 2 is fixedly connected to the upper surface of the circulating water tank 12 by a support column. The bottom left side of the circulating water tank 12 is fixedly connected to the bottom right side of the plate heat exchanger 1 by a third variable frequency centrifugal pump 13. The middle of the bottom left side of the cooling tank 8 is fixedly connected to the middle of the bottom right side of the circulating water tank 12 by a pipe fitting. Another cooling method is to cool the interior of the cooling tank 8 as a whole through the cooling pipe 11 from the front and rear sides. In this method, the coolant will not come into direct contact with the beryllium copper alloy parts. The second variable frequency centrifugal pump 10 draws the coolant in the coolant tank 2 into the cooling pipe 11. The other end of the cooling pipe 11 is connected to the circulating water tank 12. The left side of the circulating water tank 12 is connected to the bottom pipe of the plate heat exchanger 1 by the third variable frequency centrifugal pump 13. After the coolant is cooled by the plate heat exchanger 1, it is put back into the coolant tank 2, so that the coolant can be recycled. The plate heat exchanger 1 uses the BP100-BP300 domestic detachable type. The working principle of plate heat exchanger 1 is to separate two fluids at different temperatures using metal plates, achieving heat transfer from the high-temperature fluid to the low-temperature fluid, without direct contact between the two fluids. Figure 1 As shown, the plate heat exchanger 1 is horizontally positioned on the left side of the coolant tank 2 and the circulating water tank 12. The coolant tank 2 is located above the circulating water tank 12. The coolant tank 2 contains coolant at a lower temperature, while the circulating water tank 12 contains coolant at a higher temperature. The upper front right side of the plate heat exchanger 1 has a hot medium outlet, and the upper rear right side of the plate heat exchanger 1 has a cold medium outlet. The lower front right side of the plate heat exchanger 1 has a hot medium inlet, and the lower rear right side of the plate heat exchanger 1 has a cold medium inlet. Figure 3 As shown, the left side of the circulating water tank 12 is connected to the hot medium inlet at the bottom right side of the plate heat exchanger 1 by the third variable frequency centrifugal pump 13 and pipe fittings, and the left side of the coolant tank 2 is connected to the cold medium outlet at the upper rear right side of the plate heat exchanger 1 by pipe fittings. Example 2, as Figures 1-5 and Figure 7As shown, the filter assembly 4 is composed of a bracket 41, a storage slot 42, a coolant filter plate 43, and a connecting block 44. Storage slots 42 are provided on the front and rear sides of the upper center of the bracket 41 on the coolant tank 2. A coolant filter plate 43 is provided on the upper left end of the bracket 41. Connecting blocks 44 are fixedly connected to the front and rear sides of the right end of the coolant filter plate 43. The connecting blocks 44 are slidably connected within the storage slots 42. A top plate 5 is provided within the through hole 3. A fluororubber sealing ring 6 is fixedly connected to the lower surface of the upper outer side of the top plate 5. A stabilizing bolt is threaded through the four corners of the top plate 5 and the fluororubber sealing ring 6. The bottom of the stabilizing bolt is threaded into the coolant tank 2. A through hole 3 is provided at the top left end of the coolant tank 2. A bracket 41 is fixedly connected to the middle of the inner side of the coolant tank 2. A storage slot 42 is provided on both the front and rear sides of the upper middle part of the coolant tank 2. A coolant filter plate 43 is provided on the upper left end of the bracket 41. A connecting block 44 is fixedly connected to both the front and rear sides of the right end of the coolant filter plate 43. The connecting block 44 is slidably connected in the storage slot 42. A top plate 5 is provided in the through hole 3. A fluororubber sealing ring 6 is fixedly connected to the lower surface of the outer side of the upper end of the top plate 5. A stabilizing bolt is connected through the four corners of the top plate 5 and the fluororubber sealing ring 6. The bottom of the stabilizing bolt is threadedly connected to the coolant tank 2. When the coolant needs to come into direct contact with the beryllium copper alloy parts to cool them, there must be no impurities in the coolant. Therefore, the coolant needs to be filtered to prevent impurities from remaining and causing damage to the cooling pipe 11 and the beryllium copper alloy casting. Therefore, a filter mechanism is set on the upper left side of the inside of the coolant tank 2 to filter the coolant. The coolant filter plate 43 is an "L" shaped plate. The front and rear sides of the right end of the coolant filter plate 43 are fixedly connected to the connecting blocks 44, so that the coolant filter plate 43 can slide in the storage groove 42 opened in the coolant tank 2 through the connecting blocks 44. Installing the connecting blocks 44 makes it more convenient and prevents the position of the connecting blocks 44 from changing. After a period of use, the coolant filter plate 43 needs to be maintained regularly to prevent blockage inside the coolant filter plate 43, which would reduce the flow of coolant and the filtration effect. Therefore, a through hole 3 is opened on the top left side of the coolant tank 2 above the connecting block 44. A top plate 5 is fixedly connected to the through hole 3 by a sturdy bolt. A fluororubber sealing ring 6 is provided on the contact surface between the lower surface of the top plate 5 and the coolant tank 2. The fluororubber sealing ring 6 can seal the connection between the coolant tank 2 and the top plate 5 to prevent dust from entering the coolant tank 2 and to prevent coolant from leaking from the through hole 3. After removing the fixing bolts of the top plate 5, remove the top plate 5 from the through hole 3. The coolant filter plate 43 can be pulled upwards from the coolant tank 2 for maintenance or replacement. After the maintenance or replacement of the coolant filter plate 43 is completed, fix the top plate 5 back into the through hole 3 on the coolant tank 2 with the fixing bolts, and the circulating cooling device can continue to be used.
