Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen degassing furnaces, in particular to a nitrogen heating device for hydrogen degassing furnaces. Background Art

[0002] At present, the hydrogen degassing furnace is a special heat treatment equipment, which is mainly used to remove the hydrogen content in metal materials, so as to improve the mechanical properties and fatigue resistance of the materials. In the process of metal material processing, especially in high temperature environment, the materials are prone to defects such as hydrogen embrittlement, which affects the quality and performance of the materials. The hydrogen degassing furnace can effectively remove these hydrogen elements and improve the quality and reliability of the materials through specific heating and atmosphere control processes.

[0003] However, when the existing hydrogen degassing furnace is in use, nitrogen is generally heated in the furnace. The heated nitrogen will remain motionless in the furnace due to the lack of external force. The non-flow of nitrogen means that the heat cannot be evenly transferred to every corner of the furnace, resulting in uneven temperature distribution in the furnace, which will cause uneven heating of the material. Due to the uneven temperature distribution, different parts of the material are heated to different degrees, resulting in increased thermal stress, thereby increasing the risk of cracking and deformation of the material. Therefore, it is necessary to design a nitrogen heating device for a hydrogen degassing furnace that can allow nitrogen to flow in the furnace when the nitrogen is heated. Utility Model Content

[0004] In order to solve the technical problem that nitrogen does not flow by itself after being heated inside a hydrogen degassing furnace, the utility model provides a nitrogen heating device for a hydrogen degassing furnace.

[0005] The utility model is implemented by the following technical scheme: a nitrogen heating device for a hydrogen degassing furnace, comprising a hydrogen degassing furnace, a nitrogen pipe is provided on one side of the hydrogen degassing furnace, an exhaust pipe is provided on the other side of the hydrogen degassing furnace, a vacuum pump connected to the inside of the hydrogen degassing furnace is provided below the nitrogen pipe, a preheating component for preheating nitrogen is provided on the nitrogen pipe, a heating component for heating nitrogen at a constant temperature is provided inside the hydrogen degassing furnace, flow components for allowing nitrogen to flow are provided on both sides of the interior of the hydrogen degassing furnace, a driving component for driving the flow component to work is provided on one side of each of the flow components, and the heating component comprises a first electric heater fixedly installed on one side of the interior of the hydrogen degassing furnace and a second electric heater fixedly installed on the other side of the interior of the hydrogen degassing furnace.

[0006] Through the above technical solution, when the nitrogen inside the hydrogen degassing furnace is heated, the driving component will start the flow component, thereby allowing the nitrogen to flow inside the hydrogen degassing furnace.

[0007] As a further improvement of the above solution, the flow component includes a fixed plate fixedly installed inside the hydrogen degassing furnace, a plurality of rotating columns rotatably matched with the fixed plate, and a plurality of fan blades fixedly installed on each rotating column.

[0008] Through the above technical solution, the rotation of the fan blades can allow nitrogen to flow inside the hydrogen degassing furnace.

[0009] As a further improvement of the above solution, the fixing plate is installed inside the hydrogen degassing furnace at an inclined angle.

[0010] Through the above technical solution, the inclined fixed plate cooperates with the rotating column and the fan blades to better disperse and flow the nitrogen.

[0011] As a further improvement of the above scheme, the driving assembly includes a rotating rod rotatably installed inside the hydrogen degassing furnace, a plurality of first bevel gears fixedly sleeved on the rotating rod, and a second bevel gear meshingly connected to one side of each first bevel gear, and each of the second bevel gears is fixedly installed on one end of an adjacent rotating column.

[0012] Through the above technical solution, the rotation of the rotating rod will cause the first bevel gear to rotate, thereby causing the second bevel gear to rotate with the rotating column and the fan blades.

[0013] As a further improvement of the above solution, one end of each of the rotating rods passes through the hydrogen degassing furnace and extends to the outside thereof where a first gear is fixedly mounted.

[0014] Through the above technical solution, the first gear is driven to cause the rotating rod to rotate.

[0015] As a further improvement of the above scheme, a servo motor is provided on one side of the hydrogen degassing furnace, a driving rod is fixedly installed on the output end of the servo motor, a second gear is fixedly sleeved on the driving rod, and a synchronous belt for synchronous transmission is sleeved on the two first gears and the second gears.

[0016] Through the above technical solution, when the servo motor is started, the driving rod will drive the second gear, so that the synchronous belt will pull the first gear to rotate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model arranges a heating component, a flow component and a drive component. When nitrogen enters the hydrogen degassing furnace, the heating component heats the nitrogen. The start of the servo motor causes the drive component to operate, thereby turning on the flow component. In this way, the nitrogen inside the hydrogen degassing furnace flows in the furnace, so that the heating inside the hydrogen degassing furnace is more uniform. This arrangement can not only allow the heated nitrogen to flow so that the inside of the hydrogen degassing furnace is heated uniformly, but also avoid the increase of thermal stress caused by uneven heating of materials.

[0026] Combination Figure 2 and Figure 3 The flow component includes a fixed plate 701 fixedly installed inside the hydrogen degassing furnace 1, a plurality of rotating columns 702 rotatably matched with the fixed plate 701, and a plurality of fan blades 703 fixedly installed on each rotating column 702. The fixed plate 701 is installed inside the hydrogen degassing furnace 1 at an inclined angle. The rotation of the fan blades 703 can allow the nitrogen to flow inside the hydrogen degassing furnace 1. The inclined fixed plate 701 cooperates with the rotating columns 702 and the fan blades 703 to better disperse and flow the nitrogen.

[0027] Combination Figure 2 and Figure 3 The driving assembly includes a rotating rod 801 rotatably installed inside the hydrogen degassing furnace 1, a plurality of first bevel gears 802 fixedly sleeved on the rotating rod 801, and a second bevel gear 803 meshingly connected on one side of each first bevel gear 802, each second bevel gear 803 is fixedly installed with one end of an adjacent rotating column 702, one end of each rotating rod 801 penetrates the hydrogen degassing furnace 1 and extends to the outside thereof where a first gear 9 is fixedly installed, a servo motor 10 is provided on one side of the hydrogen degassing furnace 1, a driving rod 11 is fixedly installed on the output end of the servo motor 10, a second gear 12 is fixedly sleeved on the driving rod 11, a synchronous belt 13 for synchronous transmission is sleeved on the two first gears 9 and the second gear 12, when the servo motor 10 is started, the driving rod 11 will drive the second gear 12, so that the synchronous belt 13 pulls the first gear 9 to rotate, and the rotating rod 801 rotates to rotate the first bevel gear 802, so that the second bevel gear 803 drives the rotating column 702 and the fan blade 703 to rotate.

[0028] The implementation principle of a nitrogen heating device for a hydrogen degassing furnace in the embodiment of the present application is as follows: the vacuum pump 4 first extracts the gas inside the hydrogen degassing furnace 1, then opens the exhaust pipe 3 and the nitrogen pipe 2, and then opens the preheating component 5, which includes an insulation layer and a heating rod, so that the nitrogen enters the hydrogen degassing furnace 1 after preheating and sends the residual gas inside through the exhaust pipe 3 to complete the replacement of the nitrogen. When the internal nitrogen replacement is completed, the first electric heater 601 and the second electric heater 602 are started to heat the internal nitrogen, and then the servo motor 10 is started to let the driving rod 11 drive the second gear 12 The two first gears 9 rotate, so that the synchronous belt 13 drives the two first gears 9 to rotate. The rotation of the two first gears 9 causes the rotating rod 801 to rotate, driving the first bevel gear 802 to rotate. In this way, the second bevel gear 803 meshing with the first bevel gear 802 drives the rotating column 702 to rotate, thereby rotating the fan blade 703, which will blow the nitrogen inside the hydrogen degassing furnace 1 and allow the nitrogen to flow inside the hydrogen degassing furnace 1. This arrangement can not only allow the heated nitrogen to flow so that the inside of the hydrogen degassing furnace 1 is heated evenly, but also avoid uneven heating of the material resulting in increased thermal stress.
