Description

Technical Field

[0001] This utility model relates to the field of heat treatment furnace technology, specifically a segmented heat treatment furnace suitable for thin-walled parts. Background Technology

[0002] Heat treatment furnaces are key equipment used in the process of heating, holding, and cooling workpieces to control the microstructure and properties of materials. They are widely used in the machinery manufacturing, aerospace, and automotive industries. Segmented heat treatment furnaces can process materials in segments to achieve heating and holding.

[0003] Traditional heat treatment furnaces typically heat materials first and then keep them warm. However, traditional furnaces cannot recover the waste heat after heating and instead release it directly to the outside. Furthermore, the subsequent heat preservation process requires the use of electricity, making it impossible to recover the waste heat from the furnace. This results in a certain degree of energy waste and increases production costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a segmented heat treatment furnace suitable for thin-walled parts, which has the advantages of waste heat recovery and cost reduction, and solves the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a segmented heat treatment furnace suitable for thin-walled parts, comprising a heating furnace, a partition chamber fixedly mounted on the outer wall of the heating furnace, a heat preservation furnace mounted on the outer wall of the partition chamber, a heat preservation pipe fixedly mounted on the outer wall of the heat preservation furnace, a storage box fixedly mounted at the bottom of the heating furnace, a connecting pipe fixedly mounted on the outer wall of the storage box, a recovery box fixedly mounted at the top of the heating furnace, a recovery pipe installed in the inner cavity of the recovery box, a guide pipe installed on the outer wall of the recovery pipe, a connecting groove opened at the bottom of the recovery box, a fixing pipe fixedly mounted on the outer wall of the recovery pipe, a fixing box fixedly mounted on the outer wall of the fixing pipe, an impeller rotatably connected to the inner cavity of the fixing box, a permanent magnet fixedly mounted on the outer wall of the impeller, a Hall element fixedly mounted on the outer wall of the fixing box, a display screen fixedly mounted at the top of the fixing box, a support roller fixedly mounted on the inner wall of the heat preservation furnace, a metal plate mounted on the top of the support roller, a heating pipe fixedly mounted at the top of the inner cavity of the heating furnace, and an oil pump fixedly mounted on the outer wall of the guide pipe.

[0006] As a preferred technical solution of this utility model: the outer wall of the end of the guide pipe away from the recovery pipe is connected to one end of the storage box, and the outer wall of the end of the connecting pipe away from the storage box is connected to the outer wall of the insulation pipe.

[0007] As a preferred technical solution of this utility model: the outer wall of the fixed tube away from the recovery tube is connected to the outer wall of the insulation tube, and the recovery tube is made of metallic copper.

[0008] As a preferred technical solution of this utility model: the inner cavity of the fixed tube is connected to the inner cavity of the fixed box, and the installation position of the permanent magnet corresponds to the installation position of the Hall element.

[0009] As a preferred technical solution of this utility model: the inner cavity of the recycling box is connected to the inner cavity of the heating furnace, and the Hall element is electrically connected to the display screen.

[0010] As a preferred technical solution of this utility model: the inner cavity of the heat insulation pipe is connected to the inner cavities of the connecting pipe and the fixing pipe respectively, and the outer wall of the heat insulation pipe is in contact with the outer wall of the heat insulation furnace.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This segmented heat treatment furnace, suitable for thin-walled parts, utilizes a recovery box located at the top of the heating furnace. As hot air rises in the heating furnace, it enters the recovery box, allowing it to contact the outer wall of the recovery pipe. This transfers the temperature of the hot air to the heat transfer oil within the recovery pipe, heating the oil and increasing its temperature. This temperature is then transferred to the insulation pipe, which in turn insulates the outer wall of the furnace. This allows the furnace to achieve good insulation even with relatively low electricity consumption.

[0012] 2. This segmented heat treatment furnace, suitable for thin-walled parts, uses a fixed box on the outer wall of the fixed tube and an impeller inside the fixed box. During the normal flow of heat transfer oil, the impeller is driven, causing the permanent magnet to rotate. When the permanent magnet rotates on the outer wall of the Hall element, it generates a voltage in the Hall element, which is then fed back to the display screen. The voltage signal on the display screen is used to determine whether the impeller is rotating normally, and thus whether the heat transfer oil is flowing normally. Attached Figure Description

A fixed tube 11 is fixedly mounted on the wall, a fixed box 12 is fixedly mounted on the outer wall of the fixed tube 11, an impeller 13 is rotatably connected to the inner cavity of the fixed box 12, a permanent magnet 14 is fixedly mounted on the outer wall of the impeller 13, a Hall element 15 is fixedly mounted on the outer wall of the fixed box 12, a display screen 16 is fixedly mounted on the top of the fixed box 12, a support roller 19 is fixedly mounted on the inner wall of the heat preservation furnace 3, a metal plate 17 is installed on the top of the support roller 19, a heating tube 18 is fixedly mounted on the top of the inner cavity of the heating furnace 1, and an oil pump 20 is fixedly mounted on the outer wall of the guide tube 7. In the above structure, through the recovery box 8 set on the top of the heating furnace 1 and the recovery pipe 9 set in the inner cavity of the recovery box 8, the heat generated by the heating furnace 1 enters the inner cavity of the recovery box 8 through the connecting groove 10, thereby raising the temperature in the inner cavity of the recovery box 8, and then transferring the heat to the outer wall of the recovery pipe 9, thereby raising the temperature of the heat transfer oil in the inner cavity of the recovery pipe 9.

[0017] In a preferred embodiment: the outer wall of the end of the guide pipe 7 away from the recovery pipe 9 is connected to one end of the storage box 6, and the outer wall of the end of the connecting pipe 5 away from the storage box 6 is connected to the outer wall of the insulation pipe 4. In the above structure, the storage tank 6 at the bottom of the heating furnace 1 and the oil pump 20 on the outer wall of the guide pipe 7 can draw the heat transfer oil in the inner cavity of the storage tank 6 under the action of the oil pump 20, so as to enter the inner cavity of the recovery pipe 9, thereby absorbing the heat in the inner cavity of the recovery tank 8, and passing the heat transfer oil with the increased temperature into the inner cavity of the insulation pipe 4.

[0018] In a preferred embodiment: the outer wall of the end of the fixed tube 11 away from the recovery tube 9 is connected to the outer wall of the heat insulation tube 4, and the recovery tube 9 is made of metallic copper; In the above structure, the heat transfer oil can come into contact with the high temperature inside the heat transfer tank 8 after entering the inner cavity of the heat transfer pipe 9, thereby transferring the temperature to the inner cavity of the heat transfer pipe 9, thus raising the temperature of the heat transfer oil and recovering the waste heat in the inner cavity of the heating furnace 1.

[0019] In a preferred embodiment: the inner cavity of the fixing tube 11 communicates with the inner cavity of the fixing box 12, and the mounting position of the permanent magnet 14 corresponds to the mounting position of the Hall element 15. In the above structure, the fixed box 12 provided on the outer wall of the fixed tube 11 and the impeller 13 provided in the inner cavity of the fixed box 12 can drive the impeller 13 during the flow of heat transfer oil, thereby causing the impeller 13 to rotate in the inner cavity of the fixed box 12. During the rotation of the permanent magnet 14, the Hall element 15 generates a voltage signal, thereby determining whether the heat transfer oil flows normally through the inner cavity of the fixed box 12 based on the voltage signal generated by the Hall element 15.

[0020] In a preferred embodiment: the inner cavity of the recycling bin 8 is connected to the inner cavity of the heating furnace 1, and the Hall element 15 is electrically connected to the display screen 16; In the above structure, the display screen 16 installed on the top of the fixed box 12 causes the Hall element 15 to generate a voltage signal during the rotation of the permanent magnet 14, and the voltage signal is displayed under the action of the display screen 16, so that the user can easily judge whether the heat transfer oil is flowing normally.

[0021] In a preferred embodiment: the inner cavity of the insulation pipe 4 is connected to the inner cavities of the connecting pipe 5 and the fixing pipe 11 respectively, and the outer wall of the insulation pipe 4 is in contact with the outer wall of the insulation furnace 3. In the above structure, by installing a heat-conducting pipe 4 on the outer wall of the heat-conducting furnace 3, and then introducing heated heat-conducting oil into the inner cavity of the heat-conducting pipe 4, the temperature of the heat-conducting oil can be transferred to the outer wall of the heat-conducting furnace 3 under the action of the heat-conducting pipe 4, thereby achieving auxiliary heat preservation of the outer wall of the heat-conducting furnace 3, so that the temperature of the heat-conducting furnace 3 can be maintained better, reducing the electric heating time and thus reducing the consumption of electrical energy.

[0022] Working Principle: During operation, when heating the metal plate 17, the metal plate 17 is placed inside the heating furnace 1. The heating tube 18 heats the metal plate 17 to the required temperature for heat treatment. As the heating tube 18 heats the metal plate 17, the hot air inside the heating furnace 1 diffuses upwards through the connecting groove 10, raising the temperature inside the recovery tank 8. This temperature is then transferred to the recovery tube 9, raising the temperature of the heat transfer oil inside the recovery tube 9. Under the action of the oil pump 20, the heated heat transfer oil in the recovery tube 9 enters the inner cavity of the insulation tube 4, thus stimulating the outer wall of the insulation furnace 3. The heat preservation function allows the metal plate 17 to enter the inner cavity of the heat preservation furnace 3 after heat treatment. The heat preservation process takes place within the furnace 3, and the heat transfer oil circulates under the action of the oil pump 20, thus achieving a better heat preservation effect. During the circulation of the heat transfer oil, the impeller 13 in the inner cavity of the fixed box 12 is driven to rotate. As the impeller 13 rotates, the permanent magnet 14 also rotates, causing the Hall element 15 to generate a voltage signal. The strength of the voltage signal is used to monitor whether the heat transfer oil flow is normal, thus better preserving the outer wall of the heat preservation furnace 3.
