Description

Technical Field

[0001] The utility model relates to a tubular furnace resistant to acid corrosion in a high-temperature environment, and in particular to a tubular furnace resistant to acid corrosion in a high-temperature environment applied in the field of tubular furnaces. Background Art

[0002] High-temperature, acid-resistant tube furnaces are specially designed for heating in high-temperature, acidic environments. They are typically made of high-temperature and corrosion-resistant materials, such as special alloys and ceramics. These materials can withstand high temperatures without deformation and have good resistance to acidic substances.

[0003] The specification of Chinese patent CN211552434U discloses a tubular furnace, comprising a furnace body and a furnace frame, wherein the furnace body is mounted on the furnace frame; a furnace chamber is provided in the furnace body, flange covers are mounted at both ends of the furnace chamber, and annular sealing covers are mounted at both ends of the furnace body. The utility model provides a tubular furnace, which increases the cooling efficiency of the tubular furnace.

[0004] In existing tubular furnaces, materials are manually placed. However, manual operation makes it difficult to ensure that the materials are accurately positioned in the center of the tube every time. Position deviations may occur, resulting in uneven heating of the materials and affecting the accuracy of experimental results. Therefore, it is necessary to design a tubular furnace with mechanically assisted material placement and acid corrosion resistance in a high-temperature environment to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned existing technology, the technical problem to be solved by the present invention is that the materials in the existing tubular furnace are manually added. Manual operation makes it difficult to ensure that the materials are accurately located in the center of the tube every time. Position deviations may occur, resulting in uneven heating of the materials and affecting the accuracy of the experimental results.

[0006] In order to solve the above problems, the utility model provides a tubular furnace resistant to acid corrosion in a high-temperature environment, comprising an equipment body, a heating furnace is provided on the upper side of the inner end of the equipment body, a matching slot is provided on the lower side of the inner end of the equipment body, an electric push rod is fixedly connected to the right inner wall of the matching slot, the output end of the electric push rod is fixedly connected to a supporting vertical rod, the upper end of the supporting vertical rod is rotatably connected to an extended inner strip, a quartz tube is installed at the inner end of the heating furnace, a mechanical clamping hand is installed at the right end of the extended inner strip, a pair of first mutually repelling magnetic blocks are fixedly connected to the upper end of the mechanical clamping hand, a high-temperature resistant contact sensor is fixedly connected to the middle of the upper inner wall of the heating furnace, the lower end of the high-temperature resistant contact sensor is fixedly connected to a spring, and the lower end of the spring is fixedly connected to a second mutually repelling magnetic block.

[0007] In the above-mentioned tubular furnace that is resistant to acid corrosion in a high-temperature environment, this solution allows the mechanical gripper to grip the material box and transport it to a designated position in the middle of the quartz tube, and can accurately place the material in the middle of the transparent tube to ensure that the material is heated evenly during the heating process. Compared with manual feeding, position deviation is avoided, thereby ensuring the accuracy of the experimental results and avoiding manual contact of staff with high-temperature areas. The mechanical device can place the material in the correct position at one time, thereby improving work efficiency and avoiding the risk of material tipping due to uneven force during manual feeding.

[0008] As a further improvement of the present application, the inner end of the mechanical clamping hand clamps a material box, and the material box extends to the middle position inside the quartz tube.

[0009] As a further improvement of the present application, the second mutually exclusive magnetic block and the end of the first mutually exclusive magnetic block that are close to each other are in a mutually exclusive state.

[0010] As a further improvement of the present application, both left and right ends of the quartz tube are provided with tube plugs, and both left and right ends of the quartz tube are installed with corrosion-resistant sealing flanges.

[0011] As another improvement of the present application, a valve is installed at the end of the corrosion-resistant sealing flange away from the quartz tube, and a pressure gauge is connected to the outside of the valve at the left end.

[0012] As another improved supplement of the present application, the inner wall of the mechanical clamping hand is fixedly connected with a non-slip inner liner, and the non-slip inner liner is in contact with the outer wall of the material box.

[0013] As another improved supplement of the present application, a plurality of mounting holes are provided at the upper end of the mechanical clamping hand, and the plurality of mounting holes are movably connected to the corresponding first mutually exclusive magnetic blocks.

[0014] In summary, this solution sets the mechanical clamping arm in the middle position of the lower inner wall of the heating furnace, and clamps the material box in the mechanical clamping arm, and the electric push rod can drive the extended inner strip to move laterally in the quartz tube. During the displacement process, once the first mutually repulsive magnetic block moves to the bottom of the mechanical clamping arm, the two first mutually repulsive magnetic blocks above the first mutually repulsive magnetic block can generate mutual repulsion with the second mutually repulsive magnetic block. After bouncing, the second mutually repulsive magnetic block contacts the high-temperature resistant contact sensor. After receiving the relevant signal, the high-temperature resistant contact sensor can stop the displacement path of the electric push rod linked to it through the external control terminal, so that the mechanical clamping arm can clamp the material box and transport it to the designated position in the middle of the quartz tube, and can accurately place the material in the middle position of the transparent tube to ensure that the material is heated evenly during the heating process.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 2-7 A tubular furnace resistant to acid corrosion in a high-temperature environment is shown, comprising an equipment body 1, a heating furnace 2 is provided on the upper side of the inner end of the equipment body 1, a matching slot 8 is provided on the lower side of the inner end of the equipment body 1, an electric push rod 9 is fixedly connected to the right inner wall of the matching slot 8, the output end of the electric push rod 9 is fixedly connected to a supporting vertical rod 10, the upper end of the supporting vertical rod 10 is rotatably connected to an extended inner bar 11, a quartz tube 3 is installed at the inner end of the heating furnace 2, a mechanical clamping hand 12 is installed at the right end of the extended inner bar 11, the upper end of the mechanical clamping hand 12 is fixedly connected to a pair of first mutually exclusive magnetic blocks 13, a high-temperature resistant contact sensor 19 is fixedly connected to the middle part of the upper inner wall of the heating furnace 2, the lower end of the high-temperature resistant contact sensor 19 is fixedly connected to a spring 18, and the lower end of the spring 18 is fixedly connected to a second mutually exclusive magnetic block 14.

[0027] Figure 2-7 It is shown that the inner end of the mechanical clamping hand 12 clamps the material box 17, and the material box 17 extends to the middle position inside the quartz tube 3. The second mutually exclusive magnetic block 14 and the first mutually exclusive magnetic block 13 are in a mutually exclusive state at one end close to each other. Pipe plugs 7 are provided at both ends of the quartz tube 3, and corrosion-resistant sealing flanges 5 are installed at both ends of the quartz tube 3. A valve 6 is installed at the end of the corrosion-resistant sealing flange 5 away from the quartz tube 3. The valve 6 at the left end is externally connected to a pressure gauge 4. The inner wall of the mechanical clamping hand 12 is fixedly connected to a non-slip liner 16, and the non-slip liner 16 is in contact with the outer wall of the material box 17.

[0028] Figure 1-7 It is shown that the present solution sets the mechanical clamping hand 12 in the middle of the lower inner wall of the heating furnace 2, and clamps the material box 17 in the mechanical clamping hand 12, and the electric push rod 9 can drive the extended inner bar 11 to move laterally in the quartz tube 3. During the displacement process, once the first mutually repelling magnetic block 13 moves to the bottom of the mechanical clamping hand 12, the two first mutually repelling magnetic blocks 13 above the first mutually repelling magnetic block 13 can generate mutual repulsion with the second mutually repelling magnetic block 14, and the second mutually repelling magnetic block 14 can rebound upward after receiving the mutual repulsion force. After the rebound, the second mutually repelling magnetic block 14 contacts with the high-temperature resistant contact sensor 19. After receiving the relevant signal, the high-temperature resistant contact sensor 19 can stop the displacement path of the electric push rod 9 linked to it through the external control terminal, so that the mechanical clamping hand 12 can clamp the material box 17 and By transporting it to the designated position in the middle of the quartz tube 3, the material can be accurately placed in the middle position of the transparent tube, ensuring that the material is heated evenly during the heating process. Compared with manual feeding, it avoids position deviation, thereby ensuring the accuracy of the experimental results and avoiding manual contact with high-temperature areas by the staff. The mechanical device can place the material in the correct position at one time, improving work efficiency and avoiding the risk of material tipping due to uneven force during manual feeding. At the same time, when the mechanical clamping hand 12 clamps the material box 17, an anti-slip liner 16 can be set at the position where the inner side of the mechanical clamping hand 12 contacts the material box 17. The anti-slip liner 16 can increase the friction when the outer wall of the material box 17 contacts the mechanical clamping hand 12, making the clamping displacement feeding path of the material box 17 more stable.

[0029] The second implementation method:

[0030] Figure 6-7 A tubular furnace resistant to acid corrosion in a high-temperature environment is shown. A plurality of mounting holes 15 are provided at the upper end of the mechanical clamping hand 12. The plurality of mounting holes 15 are movably connected to the corresponding first mutually exclusive magnetic blocks 13. In addition, a plurality of mounting holes 15 are provided on the mechanical clamping hand 12. The plurality of mounting holes 15 can be flexibly connected to the first mutually exclusive magnetic blocks 13, so that the mechanical clamping hand 12 can adapt to material boxes 17 of different lengths, making it more adaptable during use.

[0031] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
