Description

Technical Field

[0001] The utility model relates to the technical field of steel automation, in particular to a heat exchange component for improving the cooling efficiency of a salt tank air cooling device. Background Art

[0002] A heat exchange component is a device used to transfer heat from one fluid to another without mixing the two fluids. These components are used in a wide variety of industrial and commercial systems, such as refrigeration, heating, power generation, and chemical processes.

[0003] The salt bath, a specially designed quenching device, holds a fixed amount of salt solution and heats the solution via electric heating tubes. In the heat treatment workshop of the steel plate plant, the wire rods are heated in a salt bath furnace before entering the salt bath for quenching. The heat from the wire rods in the furnace (process temperature 910°C) raises the temperature of the salt solution (process temperature 515°C). A stirring system maintains the uniformity of the solution, ensuring uniform temperature distribution during the cooling process, minimizing deformation and stress concentration. Some advanced quenching salt baths are also equipped with a circulating cooling system, which cools the brine via a heat exchanger to maintain a stable quenching temperature.

[0004] For example, an isothermal quenching salt bath tank with Chinese patent publication number CN219449766U uses a ceramic plate set in a ceramic cylinder. A lifting device drives the ceramic plate up and down, allowing the molten salt in the salt bath tank body to flow and transfer quickly. This reduces the temperature difference between different parts of the salt bath tank, ensuring the quenching effect. However, traditional heat exchange components are still used for heat exchange and heat dissipation.

[0005] Most of the current traditional salt tank cooling devices use a single vertical U-shaped heat exchange component and use air cooling to ensure the process temperature of the salt solution. However, when wire production gradually increases the number of lines to ten, the traditional vertical U-shaped heat exchange component cannot meet the cooling efficiency, making it impossible to meet the cooling requirements, resulting in salt temperature exceeding the process, further affecting the production quality of the wire, causing product waste and low production efficiency.

[0025] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0026] See attached Figure 1-2 As shown, a heat exchange component for improving the cooling efficiency of a salt tank air cooling device includes a support plate 1, a first connecting seat 5 and a second connecting seat 10; an air inlet tube 2 is fixedly installed on one side of the upper surface of the support plate 1, and an air outlet tube 3 is fixedly installed on the other side of the upper surface of the support plate 1, and a vertical air inlet duct 4 connected to the bottom end of the air inlet tube 2 is provided on one side of the upper surface of the first connecting seat 5, and a vertical air outlet duct 6 connected to the bottom end of the air outlet tube 3 is provided on the other side of the upper surface of the first connecting seat 5. A first air trough group connected to the bottom end of the vertical air inlet duct 4 is opened on one side of the interior of the first connecting seat 5, and the first air trough group includes a plurality of air inlet troughs 12. A second air trough group connected to the bottom end of the vertical air outlet duct 6 is provided on one side of the interior of the first connecting seat 5; the second air trough group includes a plurality of air outlet troughs 7 connected to the bottom end of the vertical air outlet duct 6, and the air outlet of the first air trough group and the air inlet of the second air trough group both extend to the front of the first connecting seat 5. A connecting groove 11 is provided inside the second connecting seat 10, and the air inlet of the second connecting seat 10 is provided with a horizontal air inlet duct 9 connected to the second air trough group, and the air outlet of the second connecting seat 10 is provided with a horizontal air outlet duct 8 connected to the second air trough group. The first air trough group and the second air trough group are not connected to each other.

[0027] When the salt tank needs to be cooled, the cooling device transports the cold air through the air inlet pipe 2 to the inside of the vertical air inlet duct 4, and then the cold air passes through the first connecting seat 5 into the inside of the horizontal air inlet duct 9, and then passes through the connecting groove 11 inside the second connecting seat 10, the horizontal air outlet duct 8, the air outlet groove 7 and the vertical air outlet duct 6 and is discharged through the air outlet pipe 3. When the cold air circulates inside the device, the salt solution in the salt tank can exchange heat with the cold air through the vertical air inlet duct 4, the horizontal air inlet duct 9, the horizontal air outlet duct 8 and the vertical air outlet duct 6, thereby cooling down.

[0028] Moreover, compared with the traditional single vertical pipe heat exchange, the arrangement of the vertical air inlet duct 4, the horizontal air inlet duct 9, the horizontal air outlet duct 8 and the vertical air outlet duct 6, the vertical air inlet duct 4 and the vertical air outlet duct 6 in this device have the same vertical pipe heat exchange, while the horizontal air inlet duct 9 and the horizontal air outlet duct 8 can perform horizontal pipe heat exchange to increase the heat dissipation area. Compared with the traditional single vertical pipe heat exchange method, during the actual test process, this device took the opportunity of debugging production to gradually increase the wiring, and at the same time tracked the temperature changes of the salt tank and the spring. It was tested that when the current wiring increased to eleven lines, the temperature fluctuation of the salt tank was significantly reduced compared with the previous period, which can normally meet the normal process temperature requirements while improving the production efficiency.

[0029] Furthermore, a third sealing ring is provided between the air inlet of the second connecting seat 10 and the horizontal air inlet duct 9, and between the air outlet of the second connecting seat 10 and the horizontal air outlet duct 8. When the second connecting seat 10 is connected to the horizontal air outlet duct 8 and the horizontal air inlet duct 9, the third sealing ring can seal the gap between the horizontal air outlet duct 8, the horizontal air inlet duct 9 and the second connecting seat 10.

[0030] according to Figure 3 As shown, the air inlet at the top of each air inlet slot 12 is connected to the corresponding bottom end of each vertical air inlet duct 4, each air inlet slot 12 is arranged in an L shape, and there are multiple vertical air inlet ducts 4. The top of each vertical air inlet duct 4 is connected to the inner cavity of the air inlet cylinder 2, and the air inlet cylinder 2, the vertical air inlet duct 4, the first connecting seat 5, the horizontal air inlet duct 9 and the second connecting seat 10 form an L-shaped air inlet assembly.

[0031] The number of air inlet slots 12 corresponds to the vertical air inlet duct 4 and the horizontal air inlet duct 9. The first connecting seat 5 can be connected to the vertical air outlet duct 6 through the slot, and the L-shaped air inlet component allows the device to replace the original single vertical heat exchange component, thereby increasing the heat exchange area of ​​the device without affecting the normal operation of the salt tank.

[0032] Furthermore, a first sealing ring is respectively provided between the air inlet of each air inlet slot 12 and the vertical air inlet duct 4 and between the air outlet of the air inlet slot 12 and the horizontal air inlet duct 9. The first sealing ring can be used to seal the gap between the outer ring of the ports of the vertical air inlet duct 4 and the horizontal air inlet duct 9 and the air inlet and outlet of the air inlet slot 12.

[0033] according to Figure 4 As shown, there are multiple vertical air outlet ducts 6, the top of each vertical air outlet duct 6 is connected to the inner cavity of the air outlet cylinder 3, and each air outlet slot 7 is arranged in an L shape, and the air outlet at the top of each air outlet slot 7 is connected to the corresponding bottom end of each vertical air outlet duct 6, and the air outlet cylinder 3, the vertical air outlet duct 6, the first connecting seat 5, the horizontal air outlet duct 8 and the second connecting seat 10 form an L-shaped air outlet component.

[0034] The number of air outlet slots 7 corresponds to the vertical air outlet duct 6 and the horizontal air outlet duct 8, and the L-shaped air outlet component is used to adapt to the L-shaped air inlet component, so that the overall device is designed in an L shape. While increasing the heat exchange area, the design of multiple pipes can further improve the efficiency of heat exchange.

[0035] Furthermore, a second sealing ring is respectively provided between the air inlet of the air outlet slot 7 and the horizontal air outlet duct 8 and between the air outlet of the air outlet slot 7 and the vertical air outlet duct 6. The second sealing ring can be used to seal the gap between the outer ring of the ports of the vertical air outlet duct 6 and the horizontal air outlet duct 8 and the air inlet and outlet of the air outlet slot 7.

[0036] When installing the device, first select the corresponding size according to the size of the salt tank, and then install the device at the corresponding position inside the salt tank, and the support plate 1 should be located outside the salt tank, the support plate 1 and the frame of the salt tank are fixed by screws, and the air inlet of the air cooling device is connected to the air inlet pipe 2, and the air outlet is connected to the air outlet pipe 3 for cold air circulation. When the temperature of the salt solution inside the salt tank is too high and needs to be dissipated, the air cooling device is started, so that the cold air passes through the air inlet pipe 2 and passes through the vertical air inlet duct 4, the air inlet slot 12, the horizontal air inlet duct 9, the connecting slot 11, the horizontal air outlet duct 8, the air outlet slot 7, the vertical air outlet duct 6 and finally is discharged through the air outlet pipe 3. During the cold air circulation process, the salt solution can use the vertical air inlet duct 4, the horizontal air inlet duct 9, the vertical air outlet duct 6 and the horizontal air outlet duct 8 as the medium for heat exchange with the cold air.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
