Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, and in particular relates to a stainless steel high-pressure reaction vessel. Background Technology

[0002] In many fields such as chemical engineering, pharmaceuticals, and materials synthesis, chemical reactions often need to be carried out under high pressure. Stainless steel high-pressure reactors have become a commonly used equipment for realizing such high-pressure reactions due to their good corrosion resistance and suitable processing performance.

[0003] Currently, most existing stainless steel reactors are single-layer structures. In actual use, the temperature rises after heating, which causes thermal deformation. Furthermore, the heat loss inside such single-layer stainless steel reactors is relatively fast, resulting in poor energy efficiency. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a stainless steel high-pressure reactor. By setting an outer shell and an inner shell, and setting a connecting block between the outer shell and the inner shell, the thermal deformation can be effectively reduced. By setting heat insulation cotton in the cavity between the outer shell and the inner shell, the heat exchange between the inner shell and the outside energy is reduced, the heat retention effect is improved, and thus the energy saving is improved.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stainless steel high-pressure reactor includes an outer shell, an inner shell, and a stirring mechanism. The inner shell is fixed to the inner cavity of the outer shell via several connecting blocks. Insulation cotton is installed in the cavity between the outer and inner shells. Support legs are fixed to the bottom of the outer shell. Feeding pipes are installed at the feeding ports at the upper ends of both the outer and inner shells, and discharge pipes are installed at the discharge ports at the bottom of both shells. The stirring mechanism includes a rotating shaft, a motor, a crossbar, and propeller blades. The rotating shaft is rotatably connected inside the outer and inner shells. A motor connected to the rotating shaft is installed on the upper side of the outer shell. Two corresponding horizontal bars are fixed on both sides of the rotating shaft, and propeller blades are fixed between the corresponding horizontal bars. By setting an outer and inner vessel shell and a connecting block between the outer and inner vessel shells, the thermal deformation can be effectively reduced. By setting heat insulation cotton in the cavity between the outer and inner vessel shells, the heat exchange between the inner vessel shell and the outside energy is reduced, improving the heat retention effect and thus improving energy efficiency. The stirring mechanism adopts a propeller blade structure, which can generate shear force on the material at different positions during stirring, so that the material is quickly dispersed and mixed, improving the reaction effect.

[0007] Furthermore, a scraper is fixed to the bottom end of the rotating shaft. The scraper has a "U" shaped structure and is slidably connected to the bottom inner wall of the inner vessel shell. By setting the scraper, material sedimentation is prevented and the material at the bottom can be fully turned over.

[0008] Furthermore, a reinforcing rod is fixed on the rotating shaft, and both ends of the reinforcing rod are fixed to the inner side of the vertical end of the scraper. By setting the reinforcing rod, the stability of the scraper during use is ensured.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. By setting an outer and inner vessel shell and a connecting block between them, thermal deformation can be effectively reduced. By placing insulation cotton in the cavity between the outer and inner vessel shells, the heat exchange between the inner vessel shell and the outside energy is reduced, improving the heat retention effect and thus improving energy efficiency. The stirring mechanism adopts a propeller blade structure, which can generate shear force on the material at different positions during stirring, so that the material is quickly dispersed and mixed, improving the reaction effect.

[0011] 2. By setting up scraper blades, material sedimentation is prevented, and the material at the bottom can be fully turned over. By setting up reinforcing rods, the stability of the scraper blades is ensured. Attached Figure Description

[0016] See appendix Figure 1 As shown, a stainless steel high-pressure reactor includes an outer shell 1, an inner shell 2, and a stirring mechanism 7. The inner shell 2 is fixed to the inner cavity of the outer shell 1 by several connecting blocks 3. Insulation cotton 9 is provided in the cavity between the outer shell 1 and the inner shell 2. Support legs 4 are fixed to the bottom side of the outer shell 1. Feeding pipes 5 are installed at the feeding ports at the upper ends of the outer shell 1 and the inner shell 2. Discharge pipes 6 are installed at the discharge ports at the bottom sides of the outer shell 1 and the inner shell 2. The stirring mechanism 7 includes a rotating shaft 71, a motor 72, a crossbar 73, and a propeller blade 74. The rotating shaft 71 is rotatably connected inside the outer shell 1 and the inner shell 2. A motor 72 connected to the rotating shaft 71 is installed on the upper side of the outer shell 1. Two vertically corresponding horizontal bars 73 are fixed on both the left and right sides of the rotating shaft 71, and propeller blades 74 are fixed between the vertically corresponding horizontal bars 73. By setting an outer vessel shell 1 and an inner vessel shell 2, and setting a connecting block 3 between the outer vessel shell 1 and the inner vessel shell 2, the thermal deformation can be effectively reduced. By setting heat insulation cotton 9 in the cavity between the outer vessel shell 1 and the inner vessel shell 2, the heat exchange between the inner vessel shell 2 and the outside energy is reduced, the heat retention effect is improved, and thus the energy saving is improved. The stirring mechanism 7 adopts a propeller blade 74 structure, which can generate shear force on the material at different positions during stirring, so that the material is quickly dispersed and mixed, improving the reaction effect.

[0017] A scraper 8 is fixed at the bottom of the rotating shaft 71. The scraper 8 has a "U" shaped structure and is slidably connected to the bottom inner wall of the inner vessel shell 2. By setting the scraper 8, material sedimentation is prevented and the material at the bottom can be fully turned over.

[0018] A reinforcing rod is fixed on the rotating shaft 71. The two ends of the reinforcing rod are fixed to the inner side of the vertical end of the scraper 8. By setting the reinforcing rod, the stability of the scraper 8 is ensured.

[0019] Working principle: The material is added into the inner cavity of the inner vessel shell 2 through the feeding pipe 5. The motor 72 drives the propeller blade 74 to rotate through the rotating shaft 71 and the crossbar 73 to stir and mix the material. The reacted material is discharged through the discharge pipe 6. The propeller blade 74 can generate shear force on the material at different positions during stirring, so that the material is quickly dispersed and mixed, improving the reaction effect. By setting the outer vessel shell 1 and the inner vessel shell 2, and setting the connecting block 3 between the outer vessel shell 1 and the inner vessel shell 2, the thermal deformation can be effectively reduced. By setting the heat insulation cotton 9 in the cavity between the outer vessel shell 1 and the inner vessel shell 2, the heat exchange between the inner vessel shell 2 and the outside energy is reduced, improving the heat retention effect and thus improving energy saving. By setting the scraper 8, the material is prevented from settling and the material at the bottom can be fully turned over. By setting the reinforcing rod, the stability of the scraper 8 is ensured.
