[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0035] This invention provides an industrial electrically heated reaction vessel through improvements, such as... Figures 1-11 As shown, the vessel includes a vessel body 1 and a top cover 9. Multiple locking cavities 4 are formed on the inner wall of the top of the vessel body 1. Each locking cavity 4 includes an insertion part 401 and a moving part 402. The vertical depth of the insertion part 401 is greater than the vertical depth of the moving part 402. A swing cavity 5 communicating with the locking cavity 4 is formed on the outer wall of the vessel body 1. A sliding groove 6 communicating with the swing cavity 5 is formed on the outer wall of the vessel body 1 in the vertical direction. Multiple vertical inserts 11 located within the insertion part 401 are movably installed inside the top cover 9. A heating shell 27 can also be detachably installed on the outer wall of the vessel body 1. Multiple mounting lugs 28 are provided on the top of the heating shell 27. A slider 29 is provided on the inner wall of the mounting lugs 28, and the slider 29 is slidably disposed within the sliding groove 6.

[0036] This industrial electric heating reactor is mainly divided into three parts: the reactor body 1, the top cover 9, and the heating shell 27. In use, the top cover 9 is first installed on the top of the reactor body 1, and the vertical insert 11 is lowered into the insertion part 401. Then, the heating shell 27 is inserted from below onto the outside of the reactor body 1, and the slider 29 slides upward along the sliding groove 6. When it slides to the side of the limiting cavity 7, the heating shell 27 is rotated clockwise by the handle 30, at which point the slider 29 falls into the limiting cavity 7. Then, the motor 16 drives the gear ring 13 to rotate. When the gear ring 13 rotates clockwise, the horizontal insert 14 moves from the moving part 402 to the insertion part 401. At this time, the horizontal insert 14 presses against the vertical insert 11, and the horizontal part 1102 moves downward and fits against the bottom of the insertion part 401. The linkage hole 21 on the horizontal insert 14 connects to the first pipe 18 below and the second pipe 22 above, thus simultaneously locking the top cover 9 and connecting the pipelines. At this time, the arc plate 15 enters the limiting cavity 7 from the receiving cavity 8, and the protrusion 1501 on the side enters the limiting cavity 7 and abuts against the side of the slider 29 for limiting.

[0037] Then, the top cover 9 and the vessel body 1 are preheated by external equipment. After preheating, the various raw materials in the vessel body 1 are heated and further reacted through the heating pipe network 32.

[0038] See appendix Figure 6 - Appendix Figure 7 The top cover 9 has multiple reset cavities 10 facing the direction of gravity. The vertical plug 11 includes a vertical part 1101 and a horizontal part 1102. An elastic element 12 is connected to the top of the vertical part 1101. The vertical plug 11 is movably disposed in the reset cavity 10 through the elastic element 12.

[0039] In this embodiment: During installation, the top cover 9 is first installed on the top of the vessel body 1, and the vertical insert 11 is lowered into the insertion part 401. When the gear ring 13 rotates clockwise, the horizontal insert 14 moves from the moving part 402 to the insertion part 401. At this time, the vertical insert 11 moves downward and fits against the bottom of the insertion part 401, and the elastic element 12 is stretched. When the gear ring 13 rotates counterclockwise, the horizontal insert 14 disengages from the vertical insert 11. At this time, the vertical insert 11 retracts upward into the reset cavity 10 under the action of the elastic element 12.

[0040] See appendix Figure 6 - Appendix Figure 7 A limiting groove 1201 is provided on the inner wall of the reset cavity 10, and a limiting block 1202 is provided on the outer wall of the vertical part 1101. The limiting block 1202 is slidably disposed in the limiting groove 1201.

[0041] In this embodiment: when the vertical plug 11 reciprocates along the reset cavity 10, in order to improve the stability during movement and to vertically limit the vertical plug 11, a mutually cooperating limiting groove 1201 and limiting block 1202 structure is designed.

[0042] See appendix Figure 2 - Appendix Figure 4 A gear ring 13 is rotatably mounted on the outer wall of the vessel body 1. Multiple horizontal inserts 14 are fixedly installed on the inner wall of the gear ring 13. The horizontal inserts 14 are movably installed in the locking cavity 4 and are used to lock the vertical inserts 11.

[0043] In this embodiment, both the horizontal insert 14 and the horizontal part 1102 are provided with sliding tables on their edges. When the gear ring 13 rotates clockwise, the horizontal insert 14 moves from the moving part 402 to the insertion part 401. At this time, the horizontal insert 14 presses against the vertical insert 11, and the horizontal part 1102 moves downward and fits against the bottom of the insertion part 401. At this time, the linkage hole 21 on the horizontal insert 14 is connected to the first pipe 18 below and the second pipe 22 above, respectively, so as to simultaneously lock the top cover 9 and connect the pipes.

[0044] In this embodiment: when the gear ring 13 rotates counterclockwise, the horizontal plug 14 moves from the insertion part 401 to the moving part 402. At this time, the horizontal plug 14 disengages from the vertical plug 11, and the vertical plug 11 retracts upward into the interior of the top cover 9. At this time, the linkage hole 21 on the horizontal plug 14 is misaligned with the first pipe 18 below and the second pipe 22 above, thereby simultaneously unlocking the top cover 9 and closing the pipes.

[0045] See appendix Figure 2 and attached Figure 4 The outer wall of the vessel body 1 is provided with a limiting cavity 7 and a receiving cavity 8 that communicate with the slide groove 6. The limiting cavity 7 and the receiving cavity 8 are located on both sides of the slide groove 6. Multiple arc plates 15 are also fixedly provided at the bottom of the gear ring 13. The side of the arc plate 15 is also provided with a protrusion 1501, which is used to limit the slider 29.

[0046] In this embodiment: when the heating housing 27 needs to be installed, the heating housing 27 is first inserted into the outside of the vessel body 1 from below, and the slider 29 slides upward along the slide groove 6. When it slides to the side of the limiting cavity 7, the heating housing 27 is then rotated clockwise by the handle 30. At this time, the slider 29 falls into the limiting cavity 7. Since the height of the slider 29 is the same as the height of the limiting cavity 7, the heating housing 27 is now vertically limited.

[0047] In this embodiment: when the gear ring 13 rotates clockwise, the arc plate 15 enters the limiting cavity 7 from the receiving cavity 8. At this time, the arc plate 15 is located in the slide groove 6, and the protrusion 1501 on the side enters the limiting cavity 7 and abuts against the side of the slider 29, thereby limiting the heating shell 27 in the horizontal direction.

[0048] In this embodiment: when the gear ring 13 rotates counterclockwise, the arc plate 15 enters the receiving cavity 8 from the limiting cavity 7, and then the arc plate 15 retracts back into the receiving cavity 8. Then the heating shell 27 is rotated counterclockwise, and when the slider 29 enters the slide groove 6 from the limiting cavity 7, it slides downwards and inspects the heating pipe network 32 inside.

[0049] See appendix Figure 1 and attached Figure 3 A motor 16 is also installed on the outer wall of the vessel body 1, and a drive gear 17 that meshes with the gear ring 13 is installed at the output end of the motor 16.

[0050] In this embodiment, a motor 16 structure is designed to drive the gear ring 13 to rotate, thereby achieving synchronous locking and unlocking of the top cover 9 and the heating housing 27.

[0051] See appendix Figure 8 and attached Figure 10 The vessel body 1 has a first pipe 18 that communicates with the locking cavity 4 inside the vertical outer wall. The vessel body 1 also has an annular connecting cavity 19 inside, and the bottom of the first pipe 18 communicates with the connecting cavity 19. The bottom of the vessel body 1 also has a horizontal pipe network 20, and the top of the pipe network 20 communicates with the connecting cavity 19. The horizontal insert 14 has a linkage hole 21 that communicates intermittently with the first pipe 18. The bottom of the vessel body 1 also has an inlet 33 that communicates with the pipe network 20.

[0052] In this embodiment: before the raw material reaction, the vessel body 1 and the top cover 9 need to be preheated, or after the reaction, the vessel body 1 and the top cover 9 need to be cooled. When the gear ring 13 rotates and locks the top cover 9, the linkage hole 21 is connected to the lower first pipe 18 and the upper second pipe 22 respectively. At this time, the inlet 33 is connected to the external heating or cooling equipment, and hot or cold air sequentially flows through the pipe network 20, the connecting cavity 19 and the first pipe 18 to connect with the top cover 9 and circulate for preheating or cooling.

[0053] See appendix Figure 5 - Appendix Figure 6 and attached Figure 11The top cover 9 has multiple second pipes 22 that communicate with the first pipe 18 inside the vertical outer wall. The top cover 9 also has an annular connecting cavity 23 inside. The top of the second pipes 22 communicates with the connecting cavity 23. The top of the top cover 9 also has a horizontal pipe network 24. The bottom of the pipe network 24 communicates with the connecting cavity 23.

[0054] In this embodiment: To further improve the preheating or cooling effect, a second pipe network 24 is also provided inside the top cover 9. In another embodiment, when the vertical insert 11 retracts into the reset cavity 10, the horizontal part 1102 on the vertical insert 11 can shield the bottom of the second pipe 22 to prevent debris from clogging the pipe after long-term use, thereby affecting the normal operation of subsequent work.

[0055] See appendix Figure 3 and attached Figure 11 Pipeline 24 also includes a ring pipe 25, and a mixing device 26 is installed on the top cover 9.

[0056] In this embodiment: To further improve the reaction efficiency by stirring the raw materials to be reacted, a stirring device 26 is designed. To avoid interference from the pipeline 24 to the output end of the stirring device 26, a ring pipe 25 structure is designed, with the output end of the stirring device 26 passing through the middle of the top cover 9 and located in the middle of the ring pipe 25.

[0057] See appendix Figure 1 and attached Figure 8 - Appendix Figure 9 The bottom of the heating shell 27 is provided with a fitting part 31 that abuts against the bottom of the vessel body 1. A heating pipe network 32 is provided between the heating shell 27 and the vessel body 1. A handle 30 is provided on the outer wall of the heating shell 27. Multiple support legs 2 are provided on the outer wall of the vessel body 1. A control panel 3 is also provided on one of the support legs 2.

[0058] In this embodiment: During heating, a heating space is formed between the heating shell 27 and the vessel body 1. To improve airtightness, the top of the fitting part 31 abuts against and seals the bottom of the vessel body 1. A handle 30 is designed to facilitate rotation of the heating shell 27 during assembly and disassembly.

[0059] In this embodiment: a control panel 3 structure is designed to control the operation of the device.

[0060] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
