Abstract
Description
Technical Field
[0001] This utility model specifically relates to a neodymium iron boron hydrogen catalytic reaction system. Background Technology
[0002] The hydrogen pulverization (HD) process for NdFeB is a key step in the preparation of high-performance NdFeB permanent magnet materials. It utilizes the grain boundary and transgranular fracture characteristics of rare-earth permanent magnet alloys during hydrogen absorption and dehydrogenation to pulverize the alloy, thereby obtaining alloy powder of the desired particle size. Traditional hydrogen pulverization uses a hydrogen pulverization furnace, which employs electric heating. This method is slow, energy-intensive, and cannot achieve rapid temperature rise. Furthermore, traditional cooling methods use water cooling, directing water to the outer periphery of the furnace, resulting in high water consumption and environmental friendliness. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of poor heating and cooling effects in the existing hydrogen crushing furnace, and to provide a neodymium iron boron hydrogen crushing reaction system.
[0004] The present invention solves the above-mentioned technical problems through the following technical solution:
[0005] A neodymium iron boron hydrogen catalytic reaction system, the neodymium iron boron hydrogen catalytic reaction system comprising a hydrogen catalytic furnace, the hydrogen catalytic furnace comprising:
[0006] The furnace body has a first inner cavity and a second inner cavity. The first inner cavity is embedded in the second inner cavity, and a closed circulation channel is formed between the first inner cavity and the second inner cavity. The circulation channel is used to allow heating or cooling fluid to be filled in to heat or cool the first inner cavity. The first end of the furnace body is connected to the circulation channel, and the second end of the furnace body is connected to the first inner cavity.
[0007] The heat insulation part is disposed on the outer periphery of the furnace body, and the heat insulation part includes a driving mechanism, a first heat insulation component and a second heat insulation component. When the first inner cavity is heated, the first heat insulation component and the second heat insulation component wrap around the outer surface of the furnace body through the driving mechanism. When the first inner cavity is cooled, the first heat insulation component and the second heat insulation component move away from the outer surface of the furnace body through the driving mechanism.
[0008] In this design, by incorporating a furnace body with a circulation channel, compared to a traditional single-walled furnace body heated by resistance wire, the circulation channel is located within the furnace body, allowing for direct fluid heating or cooling. This improves heat exchange efficiency, enabling rapid cooling and heating, and shortening the hydrogen breakup cycle. Furthermore, the insulation layer encloses the furnace body during heating, preventing heat loss and further increasing the heating rate. Compared to traditional single-walled resistance wire heating, this design consumes less energy. During cooling, the insulation layer is located away from the furnace body, accelerating heat dissipation and further shortening the hydrogen breakup cycle.
[0009] Preferably, the NdFeB-H hydrogen ionization reaction system further includes a heating circulation component and a cooling circulation component. The furnace body has an inlet and an outlet at its first end, both of which are connected to the circulation channel. The first end of the heating circulation component is connected to the inlet, and the second end of the heating circulation component is connected to the outlet. The first end of the cooling circulation component is connected to the first end of the heating circulation component, and the second end of the cooling circulation component is connected to the second end of the heating circulation component. When the first inner cavity is heated, the connection between the cooling circulation component and the heating circulation component is closed, and the circulation channel is filled with fluid through the heating circulation component for heating. When the first inner cavity is cooled, the connection between the cooling circulation component and the heating circulation component is closed, and the circulation channel is filled with fluid through the cooling circulation component for cooling.
[0010] In this scheme, the above settings enable the supply of heating and cooling fluids into the furnace body, and the fluids continuously exchange heat in the circulation channel. That is, the fluids after heat exchange flow out, so that the fluids that meet the heat exchange conditions can continuously enter the circulation channel, further improving the heat exchange efficiency and achieving rapid cooling and heating.
[0011] Preferably, a rotary joint is also provided at the first end of the furnace body, and both the inlet and the outlet are provided on the rotary joint.
[0012] In this solution, the above settings ensure that fluid can still flow in even when the furnace body is rotating.
[0013] Preferably, the hydrogen crusher further includes a support frame, and the driving mechanism is disposed on the support frame. The driving mechanism includes a first slide rail and a second slide rail. A first slider is disposed on the first insulation component, and a second slider is disposed on the second insulation component. The first slider slides on the first slide rail, and the second slider slides on the second slide rail. The support frame is also provided with a first support portion and a second support portion. The furnace body is disposed on the support frame through the first support portion and the second support portion. A gear is disposed on the outer surface of the furnace body, and the first support portion meshes with the gear.
[0014] In this solution, the above-mentioned settings are used to achieve the rotation of the furnace body and the insulation part wrapping around or moving away from the furnace body.
[0015] Preferably, the NdFeB-H hydrogen ionization reaction system further includes a waste heat recovery component, which includes a warm water tank, a cold water tank, a chilled water tank, a hot water tank, and a water source pump. The warm water tank and the cold water tank are both connected to the water source pump. The chilled water tank is connected to the cold water tank, and the warm water tank is connected to the hot water tank. The cooling circulation component includes a heat exchanger. The inlet of the heat exchanger is connected to the cold water tank, and the outlet of the heat exchanger is connected to the warm water tank. When hot water is replaced, water in the cold water tank enters the warm water tank through the heat exchanger, and water in the warm water tank is pumped into the hot water tank through the water source pump. When cold water is replaced, water in the cold water tank is pumped into the chilled water tank through the water source pump.
[0016] In this scheme, the above-mentioned settings allow the water participating in the cooling heat exchanger to flow into the hot water tank to further utilize the waste heat of the hot water. At the same time, the water in the cold water tank can also be further cooled so that the cooled water can be used for cooling operations.
[0017] Preferably, when hot water is replaced, the water temperature in the hot water tank is 50-55℃, and when cold water is replaced, the water temperature in the chilled water tank is 7-12℃.
[0018] In this solution, the water temperature of the hot water tank and the chilled water tank is limited to make reasonable use of hot and cold water.
[0019] Preferably, the heating circulation assembly further includes a first valve body, a first storage tank, a first pump body, a heat transfer furnace, a first buffer tank, and a second valve body. The first valve body is disposed at the second end of the heating circulation assembly, and the second valve body is disposed at the first end of the heating circulation assembly. The first valve body and the second valve body are sequentially arranged and connected to the first storage tank, the first pump body, the heat transfer furnace, and the first buffer tank.
[0020] In this scheme, the above-mentioned settings enable the first pump body to introduce fluid into the heat transfer furnace for heating, while the first buffer tank buffers the fluid pressure, allowing it to flow from the inlet into the circulation channel. The heat-exchanged fluid is then circulated back to the first storage tank through the outlet and the second valve body, so that the fluid in the first storage tank can be pumped back into the heat transfer furnace to achieve circulating heating.
[0021] Preferably, the cooling circulation assembly further includes a third valve body, a second buffer tank, an air cooler, a second storage tank, a second pump body, a third buffer tank, and a fourth valve body. The third valve body is disposed at the second end of the cooling circulation assembly, and the fourth valve body is disposed at the first end of the cooling circulation assembly. The second buffer tank, the air cooler, the second storage tank, the second pump body, the heat exchanger, and the third buffer tank are sequentially arranged and connected between the third valve body and the fourth valve body.
[0022] In this scheme, the above-mentioned settings enable the second pump body to guide the fluid into the heat exchanger for cooling. The cooled fluid then flows into the circulation channel from the inlet through the second buffer tank and the fourth valve body, and is circulated back to the second storage tank through the outlet and the third valve body, so that the fluid in the second storage tank can be pumped into the heat exchanger again to achieve circulating cooling.
[0023] Preferably, a branch is provided between the second buffer tank and the third buffer tank, and a fifth valve body is provided on the branch. When the third valve body and the fourth valve body are closed, the fifth valve body is opened.
[0024] In this scheme, the above-mentioned setup allows the fluid in the second storage tank to be circulated to the heat exchanger and air cooler via a branch line for cooling when no cooling is required, so that it can be used for cooling.
[0025] Preferably, a guide plate is provided in the circulation channel, and the guide plate has a unidirectional spiral structure from the inlet to the outlet.
[0026] In this scheme, the above settings are used to guide the fluid entering the circulation channel and allow the fluid to flow out quickly, thereby improving heat exchange efficiency.
[0027] The significant advantages of this invention are as follows: By incorporating a furnace body with a circulation channel, compared to traditional single-wall furnaces heated by resistance wire, the circulation channel is located within the furnace body, allowing for direct fluid heating or cooling. This improves heat exchange efficiency, enabling rapid cooling and heating, and shortening the hydrogen breakup cycle. Furthermore, the insulation layer encloses the furnace body during heating, preventing heat loss and further increasing the heating rate. Compared to traditional single-wall structures heated by resistance wire, this design consumes less energy. During cooling, the insulation layer is located away from the furnace body, accelerating heat dissipation and further shortening the hydrogen breakup cycle. Attached Figure Description

[0073] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0074] This embodiment provides a neodymium iron boron hydrogen catalytic reaction system, the specific structure of which is as follows: Figure 1 , Figure 2 and Figure 3 As shown, the NdFeB hydrogen pyrolysis reaction system includes a hydrogen pyrolysis furnace, which includes:
[0075] The furnace body 1 has a first inner cavity 11 and a second inner cavity 12. The first inner cavity 11 is embedded in the second inner cavity 12, and a closed circulation channel 13 is formed between the first inner cavity 11 and the second inner cavity 12. The circulation channel 13 is used to supply heating or cooling fluid to heat or cool the first inner cavity 11. The first end of the furnace body 1 is connected to the circulation channel 13, and the second end of the furnace body 1 is connected to the first inner cavity 11.
[0076] The heat preservation part 2 is disposed on the outer periphery of the furnace body 1, and the heat preservation part 2 includes a drive mechanism 21, a first heat preservation member 22 and a second heat preservation member 23. When the first inner cavity 11 is heated, the first heat preservation member 22 and the second heat preservation member 23 wrap around the outer surface of the furnace body 1 through the drive mechanism 21. When the first inner cavity 11 is cooled, the first heat preservation member 22 and the second heat preservation member 23 move away from the outer surface of the furnace body 1 through the drive mechanism 21.
[0077] Specifically, both the first inner cavity 11 and the second inner cavity 12 are cylindrical structures with conical ends. The first inner cavity 11 is used for the hydrogen breakage reaction, and the second inner cavity 12 is fitted onto the first inner cavity 11, forming a circulation channel 13 between them. The circulation channel 13 extends to the first end of the furnace body 1, allowing for heating or cooling of the first inner cavity 11 by injecting fluid from the first end into the circulation channel 13. The second end of the furnace body 1 communicates with the first inner cavity 11 to achieve the hydrogen breakage reaction. In this embodiment, the fluid used for heating or cooling is oil. Of course, in other embodiments, other fluids used for heat exchange in the prior art can also be used, which will not be elaborated further here. By providing a furnace body 1 with a circulation channel 13, compared to a traditional single-walled furnace body heated by resistance wire, the circulation channel 13 is located inside the furnace body 1, allowing for direct fluid injection for heating or cooling, thereby improving heat exchange efficiency, achieving rapid cooling and heating, and shortening the hydrogen breakage cycle.
[0078] In addition, the hydrogen crusher in this embodiment also includes a heat preservation section 2, which includes a drive mechanism 21, a first heat preservation element 22, and a second heat preservation element 23. The drive mechanism 21 is used to move the first heat preservation element 22 and the second heat preservation element 23 closer to or away from the furnace body 1. The first heat preservation element 22 and the second heat preservation element 23 have arc-shaped grooves on the side facing the furnace body 1, so as to effectively wrap the outer periphery of the furnace body 1 when the first heat preservation element 22 and the second heat preservation element 23 are close to the furnace body 1. The arc-shaped grooves of the first heat preservation element 22 and the second heat preservation element 23 are made of high-temperature resistant ceramic fiber material in the prior art, so as to prevent the furnace body 1 from losing heat when wrapping the furnace body 1, further improving the heating rate. Compared with the traditional resistance wire heating single-layer wall structure, it consumes less energy. Moreover, during cooling, the first heat preservation element 22 and the second heat preservation element 23 move away from the furnace body 1, accelerating heat dissipation, and simultaneously cooling the furnace body 1 with the cooling fluid, i.e., oil, further shortening the cooling cycle.
[0079] The driving mechanism 21 can be a hydraulic cylinder in the prior art. The hydraulic cylinder is set on both sides of the furnace body 1 and is connected to the first insulation component 22 and the second insulation component 23 respectively, thereby driving the first insulation component 22 and the second insulation component 23 to move closer to or away from the furnace body 1.
[0080] like Figure 4As shown, in this embodiment, the NdFeB-H hydrogen ionization reaction system further includes a heating circulation component 3 and a cooling circulation component 4. The first end of the furnace body 1 is provided with an inlet 14 and an outlet 15, both of which are connected to the circulation channel 13. The first end of the heating circulation component 3 is connected to the inlet 14, and the second end of the heating circulation component 3 is connected to the outlet 15. The first end of the cooling circulation component 4 is connected to the first end of the heating circulation component 3, and the second end of the cooling circulation component 4 is connected to the second end of the heating circulation component 3. When the first inner cavity 11 is heated, the connection between the cooling circulation component 4 and the heating circulation component 3 is closed, and the circulation channel 13 is filled with fluid for heating through the heating circulation component 3. When the first inner cavity 11 is cooled, the connection between the cooling circulation component 4 and the heating circulation component 3 is closed, and the circulation channel 13 is filled with fluid for cooling through the cooling circulation component 4.
[0081] Specifically, inlet 14 and outlet 15 are connected to heating circulation assembly 3 via pipelines. Heating circulation assembly 3 is used to fill the circulation channel 13 with heated oil to heat the first inner cavity 11. During heating, the oil continues to flow, meaning the fluid continuously exchanges heat within the circulation channel 13, and the fluid flows out after heat exchange to ensure that fluid meeting the heat exchange conditions continuously enters the circulation channel 13, further improving heat exchange efficiency and achieving rapid heating. The first end of cooling circulation assembly 4 is connected to the first end of heating circulation assembly 3, and the second end of cooling circulation assembly 4 is connected to the second end of heating circulation assembly 3. This reduces the number of pipelines at inlet 14 and outlet 15. By sealing the connection between cooling circulation assembly 4 and heating circulation assembly 3, oil from heating circulation assembly 3 or cooling circulation assembly 4 can be individually filled into circulation channel 13. The cooling circulation assembly 4 cools the first inner cavity 11 in the same way as it heats it. The cooling circulation assembly 4 is used to fill the circulation channel 13 with cooled oil to cool the first inner cavity 11. During cooling, the oil continues to flow, that is, the fluid continuously exchanges heat in the circulation channel 13. After heat exchange, the fluid flows out so that the fluid that meets the heat exchange conditions can continuously enter the circulation channel 13, further improving the heat exchange efficiency and achieving rapid cooling.
[0082] like Figure 3 As shown, in this embodiment, a rotary joint 6 is also provided at the first end of the furnace body 1, and the inlet 14 and outlet 15 are both provided on the rotary joint 6.
[0083] Specifically, the circulation channel 13 extends toward the first end of the furnace body 1 and forms an annular structure at the first end of the furnace body 1. The annular structure is used to allow oil to flow radially along the furnace body 1. The rotary joint 6 is a rotary port in the prior art. The inlet 14 and the outlet 15 are both set on the rotary joint 6 and the rotary joint 6 is connected to the annular structure. The rotary joint 6 is rotatably connected to the first end of the furnace body 1 so that when the furnace body 1 rotates and reacts, the rotary joint 6 remains stationary, so that the fluid can still flow into the circulation channel 13 when the furnace body 1 rotates.
[0084] In this embodiment, the hydrogen crusher also includes a support 7, and a drive mechanism 21 is disposed on the support 7. The drive mechanism 21 includes a first slide rail 211 and a second slide rail 212. A first slider (not shown in the figure) is disposed on the first insulation member 22, and a second slider (not shown in the figure) is disposed on the second insulation member 23. The first slider slides on the first slide rail 211, and the second slider slides on the second slide rail 212. The support 7 is also provided with a first support part 71 and a second support part 72. The furnace body 1 is disposed on the support 7 through the first support part 71 and the second support part 72. A gear (not shown in the figure) is disposed on the outer surface of the furnace body 1, and the first support part 71 meshes with the gear.
[0085] Specifically, the support 7 is set at the bottom of the furnace body 1, and the first insulation component 22 and the second insulation component 23 are set on opposite sides of the furnace body 1 and located on the support 7. The support 7 is provided with a first slide rail 211 and a second slide rail 212 corresponding to the first insulation component 22 and the second insulation component 23. The first insulation component 22 and the second insulation component 23 are provided with a first slider and a second slider corresponding to the first slide rail 211 and the second slide rail 212. The first slider and the second slider are moved by manually driving the first slide rail 211 and the second slide rail 212, or by a motor driving the first slide rail 211 and the second slide rail 212, so as to realize the movement of the first slider and the second slider, thereby realizing the first insulation component 22 and the second insulation component 23 wrapping around or moving away from the furnace body 1.
[0086] A first support part 71 is sleeved on the first end of the furnace body 1, and a second support part 72 is disposed on the second end of the furnace body 1. The first support part 71 includes a drive gear, and a gear is disposed on the first end of the furnace body 1 corresponding to the drive gear. The gear meshes with the drive gear to drive the furnace body 1 to rotate via the first support part 71. The second support part 72 includes a driven wheel, which is sleeved on the second end of the furnace body 1 to realize the rotation of the furnace body 1 and to effectively support the furnace body 1.
[0087] like Figure 4As shown, in this embodiment, the NdFeB-H hydrogen ionization reaction system further includes a waste heat recovery component 5. The waste heat recovery component 5 includes a warm water tank 51, a cold water tank 52, a chilled water tank 53, a hot water tank 55, and a water source pump 54. The warm water tank 51 and the cold water tank 52 are both connected to the water source pump 54. The chilled water tank 53 is connected to the cold water tank 52. The warm water tank 51 is connected to the hot water tank 55. The cooling circulation component 4 includes a heat exchanger 46. The inlet of the heat exchanger 46 is connected to the cold water tank 52, and the outlet of the heat exchanger 46 is connected to the warm water tank 51. When hot water is replaced, the water in the cold water tank 52 enters the warm water tank 51 through the heat exchanger 46. The water in the warm water tank 51 is pumped into the hot water tank 55 through the water source pump 54. When cold water is replaced, the water in the cold water tank 52 is pumped into the chilled water tank 53 through the water source pump 54.
[0088] Specifically, the heat exchanger 46 is a heat exchange structure in the prior art, and the water source pump 54 is a screw-type water source heat pump in the prior art. The liquid inlet of the heat exchanger 46 is connected to the cold water pool 52, and both the cold water pool 52 and the warm water pool 51 are connected to the water source pump 54. The liquid outlet of the heat exchanger 46 is connected to the warm water pool 51. A power pump is also installed between the heat exchanger 46 and the cold water pool 52. When hot water is needed, the power pump pumps the low-temperature water in the cold water pool 52 into the heat exchanger 46, thereby removing the heat from the oil in the heat exchanger 46. It can be understood that the cooling circulation assembly 4 circulates oil. At this time, the low-temperature water is heated and flows from the outlet of the heat exchanger 46 into the warm water pool 51. The water source pump 54 pumps the water in the warm water pool 51 into the hot water pool 55. The water source pump 54 itself heats the water in the warm water pool 51. The heated water can be used for heating in the factory area in winter, or for other equipment that needs hot water, such as bathing water, thus making use of waste heat recovery. Similarly, one end of the chilled water tank 53 is connected to the cold water tank 52, and the other end of the chilled water tank 53 is connected to the water source pump 54. When cold water is needed, the low-temperature water in the cold water tank 52 is pumped into the water source pump 54 for cooling, and then pumped into the chilled water tank 53. The water source pump 54 lowers the temperature of the water flowing out of the cold water tank 52 to achieve cooling of the low-temperature water, which can then be used for cooling of the plant area in summer or for cooling of main equipment (such as casting process of smelting furnace, cooling of press coils). Compared with cooling or heating room temperature water or hot water, it consumes less energy. Moreover, the energy efficiency of the water source pump 54 is between 3.5 and 4.0, which can effectively utilize low-temperature high-quality heat sources, resulting in significant energy saving and effective energy conservation.
[0089] Furthermore, in this embodiment, when hot water is replaced, the water temperature in the warm water tank 51 is 50-55°C, and when cold water is replaced, the water temperature in the chilled water tank 53 is 7-12°C. By limiting the water temperature in the warm water tank 51 and the chilled water tank 53, hot and cold water can be used more efficiently, and the heat recovery efficiency can reach over 60%.
[0090] In this embodiment, the heating circulation assembly 3 further includes a first valve body 31, a first storage tank 32, a first pump body 33, a heat transfer furnace 34, a first buffer tank 35, and a second valve body 36. The first valve body 31 is disposed at the second end of the heating circulation assembly 3, and the second valve body 36 is disposed at the first end of the heating circulation assembly 3. The first valve body 31 and the second valve body 36 are sequentially arranged and connected to the first storage tank 32, the first pump body 33, the heat transfer furnace 34, and the first buffer tank 35.
[0091] Specifically, the second valve body 36 is connected to the inlet 14 via a pipeline, and the first valve body 31 is connected to the outlet 15 via a pipeline. Along the fluid flow direction of the heating circulation assembly 3, i.e., the oil flow direction, a first storage tank 32, a first pump body 33, a heat transfer furnace 34, and a first buffer tank 35 are sequentially arranged. The first pump body 33 pumps the oil from the first storage tank 32 into the heat transfer furnace 34, which heats the oil. The heated oil flows into the first buffer tank 35 to buffer the oil pressure, and then through the second valve body 36 into the inlet 14 and from the inlet 14 into the circulation channel 13. It can be understood that the heat transfer furnace 34 is a heat transfer oil furnace for heating oil in the prior art, the first valve body 31 and the second valve body 36 are valve body structures in the prior art, the first storage tank 32 is an oil storage tank in the prior art, the first pump body 33 is a pump body capable of pumping oil in the prior art, and the first buffer tank 35 is a tank for buffering fluids in the prior art. The heat-exchanged oil is circulated back to the first storage tank 32 through outlet 15 and the first valve body 31, so that the oil in the first storage tank 32 can be pumped back into the heat transfer furnace 34 for circulating heating. It is understood that when heating the furnace body 1, the first valve body 31 and the second valve body 36 are opened simultaneously, and when cooling the furnace body 1, the first valve body 31 and the second valve body 36 are closed simultaneously. The opening or closing of the first valve body 31 and the second valve body 36 can be achieved by a PLC control component in the prior art. This embodiment does not improve the PLC control component and will not be elaborated further here.
[0092] In this embodiment, the furnace body 1 is rapidly heated by cooperating with the heating circulation assembly 3. Simultaneously, the furnace body 1 is insulated by the insulation section 2, increasing the heating speed by over 50%. The temperature rises from room temperature to 500°C in just 2 hours, shortening the overall hydrogen breakup cycle by approximately 35%. Compared to traditional electric heating methods, energy savings of 30-40% are achieved. Furthermore, temperature uniformity is controlled within ±5°C, reducing powder oxidation during the hydrogen breakup reaction caused by temperature fluctuations. The insulation section 2 enveloping the furnace body 1 ensures that the noise level during heating is below 75 decibels.
[0093] In this embodiment, the cooling circulation assembly 4 further includes a third valve body 41, a second buffer tank 42, an air cooler 43, a second storage tank 44, a second pump body 45, a third buffer tank 47, and a fourth valve body 48. The third valve body 41 is disposed at the second end of the cooling circulation assembly 4, and the fourth valve body 48 is disposed at the first end of the cooling circulation assembly 4. The second buffer tank 42, the air cooler 43, the second storage tank 44, the second pump body 45, the heat exchanger 46, and the third buffer tank 47 are sequentially arranged and connected between the third valve body 41 and the fourth valve body 48.
[0094] Specifically, the third valve body 41 is connected to the pipeline connecting the first valve body 31 and the outlet 15, and the fourth valve body 48 is connected to the pipeline connecting the second valve body 36 and the inlet 14. Along the fluid flow direction of the cooling circulation assembly 4, i.e. the oil flow direction, the second buffer tank 42, the air cooler 43, the second storage tank 44, the second pump body 45, the heat exchanger 46 and the third buffer tank 47 are arranged in sequence. The second pump body 45 is used to pump the oil in the second storage tank 44 into the heat exchanger 46. The heat exchanger 46 cools the oil. The cooled oil flows into the third buffer tank 47 to buffer the oil pressure, and then enters the inlet 14 through the fourth valve body 48 and flows into the circulation channel 13 from the inlet 14. It is understood that the air cooler 43 is a prior art cooling structure based on cooling oil, the third valve body 41 and the fourth valve body 48 are prior art valve body structures, the second storage tank 44 is a prior art oil storage tank, the second pump body 45 is a prior art pump body capable of pumping oil, and the second buffer tank 42 and the third buffer tank 47 are prior art tanks for buffering fluids. The circulated oil flows through the outlet 15, through the third valve body 41, then through the second buffer tank 42 and the air cooler 43, and finally returns to the second storage tank 44, so that the oil in the second buffer tank 42 can be pumped back into the heat exchanger 46 for circulating cooling. It is understood that the opening or closing of the third valve body 41 and the fourth valve body 48 can be achieved using a prior art PLC control component. This embodiment does not improve the PLC control component and will not be elaborated further here.
[0095] In this embodiment, the furnace body 1 is rapidly cooled by working in conjunction with the cooling circulation component 4, reducing the cooling time by 40%. It only takes 1.5 hours to cool the furnace body 1 from 500°C to 80°C. The cooling circulation component 4 and the heating circulation component 3 work together to reduce the overall energy consumption cost by more than 25% and reduce the cooling water consumption by about 50%. Based on a single unit, carbon dioxide emissions are reduced by about 20 tons per year.
[0096] It should be noted that when the furnace body 1 is heated, the third valve body 41 and the fourth valve body 48 are closed, and the first valve body 31 and the second valve body 36 are closed. Similarly, when the furnace body 1 is cooled, the third valve body 41 and the fourth valve body 48 are opened, while the first valve body 31 and the second valve body 36 are closed, so as to achieve the relative independence of the cooling circulation component 4 and the heating circulation component 3.
[0097] In this embodiment, a branch line 8 is provided between the second buffer tank 42 and the third buffer tank 47. A fifth valve body 49 is provided on the branch line 8. When the third valve body 41 and the fourth valve body 48 are closed, the fifth valve body 49 is opened.
[0098] Specifically, one end of branch 8 connects to the third valve body 41 and the second buffer tank 42, and the other end of branch 8 connects to the fourth valve body 48 and the third buffer tank 47. When the furnace body 1 is cooled, the first valve body 31, the second valve body 36, and the fifth valve body 49 are simultaneously closed, while the third valve body 41 and the fourth valve body 48 are opened, allowing the oil to circulate in the cooling circulation assembly 4 without entering branch 8. When the furnace body 1 does not need cooling, the fifth valve body 49 is opened and the third valve body 41 and the fourth valve body 48 are closed, allowing the oil to continuously circulate and cool between the second buffer tank 42, the air cooler 43, the second storage tank 44, the second pump body 45, the heat exchanger 46, and the third buffer tank 47, in preparation for the furnace body 1 to be cooled again. This allows the furnace body 1 to be cooled again without waiting for the oil to cool down, with a response time of less than 30 seconds.
[0099] In this embodiment, a guide plate (not shown in the figure) is provided within the circulation channel 13. The guide plate has a unidirectional spiral structure from the inlet 14 to the outlet 15. It is understood that the unidirectional spiral structure is a conventional spiral structure, and its unidirectional arrangement facilitates the unidirectional flow of oil from the inlet 14 to the outlet 15, preventing the oil from not flowing within the circulation channel 13 and thus affecting heat exchange efficiency. The guide plate is made of a high-temperature resistant material, such as ceramic fiber, which is readily available in the art. This achieves the purpose of guiding the fluid entering the circulation channel 13 and allowing it to flow out quickly, thereby improving heat exchange efficiency.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
