Description

Technical Field

[0001] This utility model belongs to the field of electrode foil production technology, and specifically relates to a cooling device for an electrode foil thermal furnace. Background Technology

[0002] Because aluminum foil needs to be cooled at an appropriate rate during the slow cooling process, if the cooling is too fast, it may cause the aluminum foil to stick together and break, incomplete stress release leading to cracking, and high hardness and poor bending ability. On the other hand, if the cooling is too slow, it requires a lot of waiting time and energy consumption, and will also increase the risk of oxidation and corrosion. Therefore, it is particularly important to choose a suitable slow cooling control method.

[0003] Currently, most thermal furnace cooling devices rely on airflow, water cooling, or other methods for temperature control, resulting in low cooling efficiency, limited efficiency adjustment range, and inability to meet corresponding process requirements. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a cooling device for an electrode foil thermalizing furnace.

[0005] To achieve the innovative objectives of this utility model, the following technical solutions can be used:

[0006] A cooling device for an electrode foil melting furnace includes a cooling hood covering the melting furnace, a cooling gap being formed between the cooling hood and the melting furnace, and the cooling gap being connected to a water cooling mechanism and an air cooling mechanism.

[0007] The cooling device of this invention is used to cool a heat treatment furnace. The furnace body is equipped with a material rack on which rolls of three-dimensional electrode foil to be heat-treated can be placed. A cooling hood covers the heat treatment furnace, but its inner sidewall and top surface are not in contact with the furnace, creating a cooling gap. This gap ensures that the water-cooling and air-cooling mechanisms can directly and comprehensively act on the furnace body. The water-cooling mechanism sprays cooling water into this gap, directly onto the furnace body. During the contact between the cooling water and the furnace body, and during evaporation, the water absorbs heat, achieving cooling. The air-cooling mechanism delivers a high-speed airflow into the gap. This airflow directly carries away the heat dissipated by the furnace body and promotes the evaporation of the cooling water, further improving cooling efficiency. By individually activating the air-cooling or water-cooling mechanisms, or by separately controlling the efficiency of each cooling mechanism, a wide range of cooling rate control can be achieved, meeting the process requirements for cooling after heat treatment.

[0008] In the cooling device of the electrode foil thermal furnace described above, the water cooling mechanism includes at least one spray head disposed on the top and / or side of the cooling shroud. The output end of the spray head is connected to the cooling gap and faces the thermal furnace. The input end of the spray head is connected to the water supply pipeline.

[0009] The water cooling mechanism outputs cooling water through spray heads. The top of the furnace is arc-shaped, and the spray heads can be vertically installed on the top of the cooling hood to spray cooling water towards the top of the furnace. The cooling water flows down along the arc surface of the furnace top and the side wall. Alternatively, the spray heads can be installed on the side but near the top, and the cooling water sprays onto the side wall of the furnace and flows down. During the flow, the cooling water absorbs heat from the furnace and evaporates to absorb heat, achieving efficient cooling.

[0010] In the cooling device of the electrode foil thermal furnace described above, the water supply pipeline is connected to the circulating water tank, a water pump assembly is installed on the water supply pipeline, and a water guiding assembly is provided between the cooling gap and the circulating water tank.

[0011] The cooling water output from the water-cooling mechanism is led to the circulating water pool by the water guide component after heat exchange. Then, the water pump component draws water from the circulating water pool to power the water-cooling mechanism, realizing water circulation, saving resources, and ensuring continuous cooling. Of course, the top of the cooling water pool is open, and the surface of the cooling water in the pool is in direct contact with the air, which is beneficial for the cooling water to cool down after absorbing heat. The water pump component includes a submersible pump, which is at least partially submerged below the surface of the circulating water pool. The submersible pump draws water from the bottom of the pool, and the temperature of the water at the bottom of the pool is lower than that at the surface, ensuring water cooling efficiency.

[0012] In the cooling device of the electrode foil thermal furnace described above, the water guiding component includes a water receiving trough that extends circumferentially on the outer wall of the thermal furnace. The cross-section of the water receiving trough is U-shaped, and a communication gap is provided between the bottom of the trough and the lower end of the cooling cover. The outlet of the water receiving trough is connected to the circulating water pool.

[0013] A water receiving tank is installed on the heating furnace below the cooling shroud. The cooling water output by the water cooling mechanism flows into the water receiving tank after absorbing heat, and then transitions from the water receiving tank to the circulating water pool to achieve water circulation. Moreover, the bottom of the water receiving tank and the cooling shroud are not connected or not completely connected. The communication gap formed between them is conducive to the exhaust of the air input by the air cooling mechanism, ensuring the balance of internal and external air pressure.

[0014] As an optimization, a water outlet is provided at a position in the water receiving tank away from the furnace wall of the heating furnace. A water guide pipe is provided on the water outlet, and the water guide pipe is connected to the circulating water pool to achieve the effect of guiding the cooling water to the circulating water pool.

[0015] In the cooling device of the electrode foil thermal furnace described above, the air cooling mechanism includes at least one set of cooling fans. The bottom and / or side of the cooling shroud are provided with air outlets communicating with the cooling gap. The cooling fans are connected to the air outlets. A switch plate is hinged to the air outlets. The shape of the switch plate is adapted to the air outlets and can completely close, partially open, or fully open the air outlets.

[0016] The air-cooling mechanism specifically uses a cooling fan to input high-speed airflow from the air outlet into the cooling gap. The switch plate on the air outlet is circular and can rotate around its diameter to control the opening of the air outlet, thereby controlling the air-cooling efficiency.

[0017] In the cooling device of the electrode foil thermal furnace described above, a tubular mounting platform is provided on the outer wall of the cooling cover, the cooling fan is detachably fixed inside the mounting platform, and the air outlet is located at the inner end of the mounting platform.

[0018] The mounting platform is used to accommodate and install the cooling fan. Its tubular shape protects the cooling fan, and the air outlet is located inside the mounting platform to ensure proper connection with the air outlet surface of the cooling fan.

[0019] In the cooling device of the electrode foil thermal furnace described above, the switch plate is rotatably connected to the mounting platform via a rotating shaft. At least one end of the rotating shaft passes through the mounting platform and protrudes. A rotating handle is provided on the protruding end of the rotating shaft, or the protruding end is connected to the switch driver.

[0020] The switch plate can be circular or semi-circular. The rotating shaft is fixedly connected to the switch plate, and the exposed end of the rotating shaft extends out of the mounting tube. A rotating handle can be provided for manual opening adjustment, or it can be connected to a switch driver to achieve automatic control. The switch driver can be a motor, and the output end of the motor is rotatably connected to the exposed end.

[0021] In the cooling device of the electrode foil melting furnace described above, a detachable fixing structure is provided between the cooling cover and the melting furnace. The shape of the cooling cover is adapted to the shape of the melting furnace. The cooling gap includes a top gap between the inner top surface of the cooling cover and the outer top surface of the melting furnace, and a side gap between the inner side wall of the cooling cover and the outer side wall of the melting furnace.

[0022] The detachable fixing structure is used to fix the cooling hood and the heat treatment furnace. The fixing is flexible and detachable. The shape of the cooling hood and the shape of the heat treatment furnace are adapted to each other. Both are bell-shaped. The sides and tops of the two do not directly contact each other, so that the air cooling mechanism and the water cooling mechanism can directly apply the cooling effect to the heat treatment furnace.

[0023] In the cooling device of the electrode foil heat treatment furnace described above, the detachable fixing structure includes a first connecting screw partially located in the side gap. The side wall of the cooling cover is evenly distributed with at least three side screw holes in the circumferential direction. A number of first connecting blind holes are correspondingly provided on the outer side wall of the heat treatment furnace. The first connecting screw is engaged with the side screw holes and its inner end is inserted into the first connecting blind hole.

[0024] The first connecting screw passes through the cooling shroud from the side, and its inner end is inserted into the first connecting blind hole of the heat treatment furnace. There are at least three first connecting screws evenly distributed around the circumference, which is conducive to fixing the cooling shroud and the heat treatment furnace at intervals. Moreover, the first connecting screw is made of metal and has good thermal conductivity. Its rod body is directly inserted horizontally into the side gap, and its inner end is in direct contact with the furnace body of the heat treatment furnace to absorb heat. The rod body is in full contact with the high-speed airflow of the air-cooling mechanism and the cooling water of the water-cooling mechanism to conduct away the absorbed heat. It has a similar function to heat dissipation fins and helps to improve cooling efficiency.

[0025] As a further optimization, several heat dissipation rods can be inserted into the cooling cover. The inner end of the heat dissipation rod is located in the cooling gap, and the outer end extends to the outside of the cooling cover. It can absorb the heat of the cooling gap and dissipate it to the outside, thereby further improving the cooling efficiency.

[0026] In the cooling device of the electrode foil thermal furnace described above, the detachable fixing structure includes a second connecting screw partially located in the top gap. The top of the cooling cover has at least three top screw holes evenly distributed around its circumference. The top of the thermal furnace is provided with a number of second connecting blind holes. The second connecting screw is engaged with the top screw holes and its inner end is inserted into the second connecting blind holes.

[0027] Similarly, a second connecting screw can be installed at the top of the cooling shroud. The inner end of the screw abuts against the top of the furnace, which increases the cooling efficiency and improves the vertical support capacity, ensuring the stability of the cooling shroud installation.

[0028] Compared with the prior art, the present invention has the following main advantages:

[0029] 1. A cooling gap exists between the cooling hood and the heat treatment furnace. This gap ensures that the water cooling mechanism and the air cooling mechanism can directly and comprehensively act on the furnace body. The water cooling mechanism is used to spray cooling water into the cooling gap. The cooling water can be directly sprayed onto the furnace body. During the contact between the cooling water and the furnace body and during the evaporation process, heat is absorbed to achieve cooling. The air cooling mechanism is used to deliver high-speed airflow into the cooling gap. This airflow directly carries away the heat dissipated by the furnace body and promotes the evaporation of the cooling water, further improving the cooling efficiency and meeting the process requirements for cooling after heat treatment.

[0030] 2. The cooling water output by the water-cooling mechanism is led to the circulating water pool by the water guide component after heat exchange. Then, the water pump component draws water from the circulating water pool to cool the water-cooling mechanism, realizing water circulation, saving resources, and ensuring continuous cooling.

[0031] 3. The mounting platform is used to accommodate the cooling fan. Its tubular shape protects the cooling fan. The air outlet is located inside the mounting platform to ensure proper connection with the air outlet surface of the cooling fan.

[0032] 4. The rotating shaft is fixedly connected to the switch plate, and its exposed end extends out of the mounting tube. A rotating handle can be set for manual opening adjustment, or it can be connected to a switch driver to achieve automatic control. The choice can be made according to specific needs.

[0033] 5. The first connecting screw passes through the cooling cover from the side, and its inner end is inserted into the first connecting blind hole of the heat treatment furnace. The first connecting screw is made of metal and has good heat conduction effect. Its rod body is directly inserted horizontally into the side gap, and its inner end is in direct contact with the furnace body of the heat treatment furnace to absorb heat. The rod body is in full contact with the high-speed airflow of the air-cooling mechanism and the cooling water of the water-cooling mechanism, which has a similar function to heat dissipation fins and helps to improve cooling efficiency.

[0034] 6. A second connecting screw can also be installed on the top of the cooling shroud. The inner end of the screw abuts against the top of the furnace, which increases the cooling efficiency and also improves the vertical support capacity, ensuring the stability of the cooling shroud installation.

[0043] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0044] Specific implementation examples Figure 1 , 2 As shown, the cooling device of this electrode foil thermal furnace includes a cooling cover 2 covering the thermal furnace 1, a cooling gap 3 formed between the cooling cover 2 and the thermal furnace 1, and the cooling gap 3 is connected to a water cooling mechanism 4 and an air cooling mechanism 5.

[0045] Specifically, this cooling device is used to cool the heat treatment furnace 1. The furnace body of the heat treatment furnace 1 is equipped with a material rack 13, on which the three-dimensional electrode foil roll to be heat-treated can be placed. The cooling cover 2 is placed on the heat treatment furnace 1. The inner side wall and inner top surface of the cooling cover 2 are not in contact with the heat treatment furnace 1, and there is a cooling gap 3 between them. This gap ensures that the water cooling mechanism 4 and the air cooling mechanism 5 can directly and fully act on the furnace body of the heat treatment furnace 1. The water cooling mechanism 4 is used to spray cooling water into the cooling gap 3. The cooling water can be directly sprayed onto the furnace body. During the contact between the cooling water and the furnace body and during the evaporation process, heat is absorbed to achieve cooling. The air cooling mechanism 5 is used to deliver high-speed airflow into the cooling gap 3. This airflow directly carries away the heat emitted by the furnace body on the one hand, and promotes the evaporation of the cooling water on the other hand, further improving the cooling efficiency and meeting the process requirements of cooling after heat treatment.

[0046] like Figure 1 As shown, the water-cooling mechanism 4 includes a spray head 41 mounted on the top of the cooling shroud 2. The output end of the spray head 41 is connected to the cooling gap 3 and faces the furnace 1. The input end of the spray head 41 is connected to the water supply pipe 42. The water supply pipe 42 is connected to the circulating water tank 43, and a water pump assembly 44 is mounted on the water supply pipe 42. A water guiding assembly 45 is provided between the cooling gap 3 and the circulating water tank 43. The water guiding assembly 45 includes a water receiving trough 46 extending circumferentially on the outer wall of the furnace 1. The cross-section of the water receiving trough 46 is U-shaped, and a connecting gap 47 is provided between the bottom of the trough and the lower end of the cooling shroud 2. The outlet of the water receiving trough 46 is connected to the circulating water tank 43. An outlet is provided on the water receiving trough 46 at a position away from the furnace wall of the furnace 1, and a water guiding pipe 48 is provided on the outlet.

[0047] Specifically, the water-cooling mechanism 4 outputs cooling water through spray heads 41. The top of the furnace 1 is arc-shaped, and the spray heads 41 are vertically installed on the top of the cooling hood 2, spraying cooling water towards the furnace top. The cooling water flows down along the arc surface of the furnace top and the side wall. During the flow, the cooling water absorbs heat from the furnace 1 and evaporates to absorb heat, achieving efficient cooling. The cooling water output by the water-cooling mechanism 4 is led to the circulating water pool 43 by the water guide component 45 after heat exchange. Then, the water pump component 44 draws water from the circulating water pool 43 to cool the water-cooling mechanism 4, realizing water circulation, saving resources, and ensuring continuous cooling. Of course, the top of the cooling water pool is open, and the surface of the cooling water in the pool is in direct contact with the air, which is beneficial to the cooling water after absorbing heat. The water pump component 44 is a submersible pump, which is submerged below the surface of the circulating water pool 43. The submersible pump draws water from the bottom of the pool, and the temperature of the water at the bottom of the pool is lower than that at the surface, ensuring water cooling efficiency. A water receiving tank 46 is provided on the heating furnace 1 below the cooling shroud 2. The cooling water output from the water cooling mechanism 4 flows into the water receiving tank 46 after absorbing heat, and then transitions from the water receiving tank 46 to the circulating water pool 43 to achieve water circulation. Moreover, the connecting gap 47 formed between the bottom of the water receiving tank 46 and the cooling shroud 2 facilitates the discharge of air input by the air cooling mechanism 5, ensuring the balance of internal and external air pressure. The water guide pipe 48 is connected to the circulating water pool 43 to guide the cooling water into the circulating water pool 43.

[0048] like Figure 1 , 2 As shown, the air-cooling mechanism 5 includes two sets of cooling fans 51. An air outlet 52 communicating with the cooling gap 3 is provided on the side of the cooling shroud 2. The cooling fans 51 are connected to the air outlet 52. A switch plate 53 is hinged to the air outlet 52, and the shape of the switch plate 53 is adapted to the air outlet 52. A tubular mounting platform 54 is provided on the outer wall of the cooling shroud 2. The cooling fans 51 are detachably fixed inside the mounting platform 54, and the air outlet 52 is located at the inner end of the mounting platform 54. The switch plate 53 is rotatably connected to the mounting platform 54 via a rotating shaft 55. One end of the rotating shaft 55 passes through the mounting platform 54 and protrudes, and the protruding end of the rotating shaft 55 is connected to the switch driver.

[0049] Specifically, the air-cooling mechanism 5 uses a cooling fan 51 to input high-speed airflow from the air outlet 52 into the cooling gap 3. The switch plate 53 on the air outlet 52 is circular and can rotate around its diameter to control the opening of the air outlet 52, thereby controlling the air-cooling efficiency. The mounting platform 54 is used to accommodate the cooling fan 51. Its tubular shape protects the cooling fan 51. The air outlet 52 is located inside the mounting platform 54, ensuring proper connection with the air outlet surface of the cooling fan 51. The switch plate 53 can be circular or semi-circular. A rotating shaft 55 is fixedly connected to the switch plate 53. The exposed end of the rotating shaft 55 extends outside the mounting tube and can be connected to a switch driver for automatic control. This switch driver is a motor, and the output end of the motor is rotatably connected to the exposed end.

[0050] like Figure 1 As shown, a detachable fixing structure 6 is provided between the cooling shroud 2 and the heat treatment furnace 1. The shape of the cooling shroud 2 is adapted to the shape of the heat treatment furnace 1. The cooling gap 3 includes a top gap 31 located between the inner top surface of the cooling shroud 2 and the outer top surface of the heat treatment furnace 1, and a side gap 32 located between the inner side wall of the cooling shroud 2 and the outer side wall of the heat treatment furnace 1. The detachable fixing structure 6 includes a first connecting screw 61 partially located in the side gap 32. Four side screw holes 21 are evenly distributed circumferentially on the side wall of the cooling shroud 2. A number of first connecting blind holes 11 are correspondingly provided on the outer side wall of the heat treatment furnace 1. The first connecting screw 61 is engaged with the side screw holes 21 and its inner end is inserted into the first connecting blind hole 11. The detachable fixing structure 6 includes a second connecting screw 62 partially located within the top gap 31. The top of the cooling cover 2 has three top screw holes 22 evenly distributed around its top circumference. The outer top of the heat furnace 1 is provided with several second connecting blind holes 12. The second connecting screw 62 is engaged with the top screw holes 22, and its inner end is inserted into the second connecting blind holes 12.

[0051] Specifically, the detachable fixing structure 6 is used to fix the cooling cover 2 and the heat treatment furnace 1. This fixing is flexible and detachable. The shape of the cooling cover 2 and the shape of the heat treatment furnace 1 are adapted to each other, both being bell-shaped. The sides and tops of the two do not directly contact each other, allowing the air-cooling mechanism 5 and the water-cooling mechanism 4 to directly apply a cooling effect to the heat treatment furnace 1. The first connecting screw 61 passes through the cooling cover 2 from the side, and its inner end is inserted into the first connecting blind hole 11 of the heat treatment furnace 1, realizing the spaced fixing of the cooling cover 2 and the heat treatment furnace 1. Moreover, the first connecting screw 61 is made of metal and has good thermal conductivity. Its rod body is directly inserted horizontally into the side gap 32, and its inner end is in direct contact with the furnace body of the heat treatment furnace 1 to absorb heat. The rod body is in full contact with the high-speed airflow of the air-cooling mechanism 5 and the cooling water of the water-cooling mechanism 4, conducting away the absorbed heat. It has a function similar to heat dissipation fins, which helps to improve cooling efficiency. A second connecting screw 62 is also provided on the top of the cooling cover 2. The inner end of the screw abuts against the top of the heating furnace 1, which increases the cooling efficiency and also improves the vertical support capacity, ensuring the stable installation of the cooling cover 2.

[0052] As a further optimization of this embodiment, a number of heat dissipation rods 7 are also inserted on the cooling cover 2. The inner end of the heat dissipation rod 7 is located in the cooling gap 3, and the outer end extends to the outside of the cooling cover 2. It can absorb the heat of the cooling gap 3 and dissipate it to the outside, thereby further improving the cooling efficiency.

[0053] Specific working principle: When the heat treatment furnace 1 is completed and needs to be cooled, the cooling cover 2 is placed on the heat treatment furnace 1, and the first connecting screw 61 and the second connecting screw 62 are fixed in place. The water cooling mechanism 4 and the air cooling mechanism 5 are turned on. The cooling rate is adjusted and controlled by controlling the cooling water output rate of the spray head 41 and the opening of the baffle plate. The cooling water is sprayed from the top of the heat treatment furnace 1 and flows down along the top and wall of the furnace to the water receiving tank 46. Then, it flows back to the circulating water pool 43 from the outlet of the water receiving tank 46 through the water guide pipe 48. The high-speed airflow output by the air cooling mechanism 5 directly acts on the furnace body of the heat treatment furnace 1, moves downward in the cooling gap 3 and is finally discharged outward through the connecting gap 47.

[0054] The following is a cooling status table for a specific embodiment (without a heat sink):

[0055] time Water cooling system start-up and shutdown air-cooled system opening Temperature (°C) 0-2H stop 25％ 650-580 2-4H stop 50％ 580-480 4-6H start up 75％ 480-320 6-8H start up 90％ 320-120 8-10H stop 100％ 120-55

[0056] This cooling device can greatly reduce problems such as adhesion and breakage of foil rolls during the heating process, cracking due to incomplete stress release, and poor bending ability due to high aluminum foil hardness. At the same time, it optimizes the waiting time and energy consumption in the previous cooling process and reduces the risk of oxidation and corrosion of composite three-dimensional foil.
