Technical Field

[0003] After retrieval, the existing Chinese patent publication number is: CN213995833U, which provides a device for propane dehydrogenation to produce propylene. Through a pressure detector and a temperature detector, it is convenient for people to detect the pressure and temperature inside the sandwich reaction kettle body. The inlet pipe is convenient for propane input, and the electric heater can heat the inside of the sandwich reaction kettle body through an electric heating wire, thereby improving the reaction efficiency. The outlet pipe is convenient for outputting the gas after the reaction. The first valve can control the output of the gas.

Through the three-necked feed pipe 3, gas can enter the inside of the reaction kettle 1 for reaction. A first motor 4 is fixedly connected inside the box body 2. The first motor 4 is a conventional structure and will not be elaborated here. The output end of the first motor 4 is fixedly connected with a first rotating shaft 5 that rotates and extends into the inside of the reaction kettle 1. One end of the first rotating shaft 5 away from the first motor 4 is fixedly connected with a transmission shaft 9.

A one-way transmission device is arranged inside the moving groove 33. Two cams 17 are fixedly connected to the outer surface of the transmission shaft 9. The protruding ends of the two cams 17 are arranged oppositely. Two symmetrical fixed rods 11 are fixedly connected inside the reaction kettle 1. One end of the fixed rod 11 is fixedly connected with a support ring 10. The inner surface of the support ring 10 is provided with teeth. A fixed ring 28 is fixedly connected to the outer surface of the pipe 18. Two symmetrical second limiting plates 22 are fixedly connected to the outer surface of the fixed ring 28. The cross-section of the second limiting plate 22 is in a C shape. A limiting rod 24 is fixedly connected inside the second limiting plate 22. A limiting slider 23 is arranged on the surface of the limiting rod 24. The cross-section of the limiting slider 23 is in a square shape. One side of the limiting slider 23 is fixedly connected with a material holding cylinder 14. The material holding cylinder 14 is provided with mesh holes, so that gas can enter the inside of the material holding cylinder 14 more smoothly. The catalyst for propane dehydrogenation reaction can be placed inside the material holding cylinder 14. The number of the material holding cylinders 14 is two. A first universal ball 13 is fixedly connected to the outer surface of the material holding cylinder 14. A transmission ring 12 is arranged on the outer surface of the first universal ball 13. The first universal ball 13 can rotate inside the transmission ring 12. A transmission filtering and cleaning device is arranged inside the three-necked feed pipe 3. A material movement device is arranged on the pipe 18.
[0040] A first limiting plate 8 is fixedly connected to the outer surface of the first rotating shaft 5 inside the reaction kettle 1. The first limiting plate 8 is arranged on the right side of the transmission plate 6. Limit sliders 23 are arranged at both ends of the material storage cylinder 14. The cross-section of the first limiting plate 8 is in the shape of a Chinese character 'Ri'. A limiting rod 24 is also fixedly connected inside the first limiting plate 8. Through the mutual cooperation of the first limiting plate 8 and the second limiting plate 22, the position of the material storage cylinder 14 is restricted, and the material storage cylinder 14 can rotate more smoothly. At the same time, the transmission shaft 9 drives the two cams 17 to rotate. Through the relative arrangement of the protruding ends of the two cams 17, the protruding ends of the cams 17 can push the material storage cylinder 14 to tilt around the rotation point of the first universal ball 13 during rotation, and the catalyst inside the material storage cylinder 14 is shaken, which increases the contact area between the catalyst and the gas to a certain extent, thereby increasing the catalytic speed of the catalyst for the gas to a certain extent and enabling the reaction to proceed more smoothly.
[0041] Specifically, a power gear 15 is fixedly connected to the surface of the transmission shaft 9. The power gear 15 is arranged between the two cams 17. The outer surface of the transmission ring 12 is meshed with the outer surface of the power gear 15 through teeth. The outer surface of the transmission ring 12 is meshed with the inside of the support ring 10 through teeth. Thus, when the first motor 4 drives the first rotating shaft 5 and the transmission shaft 9 to rotate, the transmission shaft 9 can drive the transmission ring 12 to rotate around the power gear 15 inside the support ring 10 through the power gear 15, and the rotation of the material storage cylinder 14 is realized, so that the catalyst inside the material storage cylinder 14 can be disturbed, enabling the propane gas to react more fully with the catalyst, and ensuring the speed of the propane dehydrogenation reaction to a certain extent.
[0042] The one-way transmission device includes an L-shaped positioning frame 31. The surface of the L-shaped positioning frame 31 is slidably connected to the inside of the moving groove 33. The cross-sections of the L-shaped positioning frame 31 and the moving groove 33 are both L-shaped. A fixing groove 30 is formed on the outer surface of the first rotating shaft 5. One side of the L-shaped positioning frame 31 close to the fixing groove 30 is inserted into the inside of the fixing groove 30. The L-shaped positioning frame 31 can slide into and out of the inside of the fixing groove 30, and the position of the transmission plate 6 is fixed and released. One side of the L-shaped positioning frame 31 close to the fixing groove 30 is provided with an inclined surface. One end of a spring 32 far from the L-shaped positioning frame 31 is fixedly connected to the inner wall of the moving groove 33. The movement of the L-shaped positioning frame 31 can compress and reset the spring 32. Two cleaning plates 7 are fixedly connected to one side of the transmission plate 6. The cleaning plates 7 are arranged outside the support ring 10.
[0043] The transmission filtering and cleaning device includes a filter plate 34, which is arranged inside the three-neck feed pipe 3. A power transmission shaft 35 extending outside the filter plate 34 is rotatably connected inside the filter plate 34. The filter plate 34 can block and filter impurities in the air entering the inside of the reaction kettle 1. A cleaning rod 36 is fixedly connected to the outer surface of the power transmission shaft 35. The cleaning rod 36 is arranged on the top of the filter plate 34. A worm gear 37 is fixedly connected to the bottom end of the power transmission shaft 35. A worm 39 meshing with the surface of the worm gear 37 is rotatably connected inside the three-neck feed pipe 3. A transmission roller 38 is fixedly connected to the outer surface of the worm 39. The transmission roller 38 is made of a material with a large frictional force. When the first rotating shaft 5 rotates clockwise, through the inclined surface provided on the L-shaped positioning frame 31, when the first rotating shaft 5 rotates clockwise, it can push the L-shaped positioning frame 31 out of the inside of the fixing groove 30, so as to realize the independent rotation of the first rotating shaft 5. When it is necessary to clean the filter plate 34, the first motor 4 drives the first rotating shaft 5 to rotate in the reverse direction. Under the action of the spring 32 on the L-shaped positioning frame 31, the first rotating shaft 5 drives the L-shaped positioning frame 31 to rotate through the fixing groove 30, so that the L-shaped positioning frame 31 drives the transmission plate 6 to rotate. The transmission plate 6 drives the transmission roller 38 to rotate through the cleaning plate 7, and the transmission roller 38 drives the power transmission shaft 35 to rotate through the worm 39 and the worm gear 37.
[0044] Specifically, the cleaning rod 36 can scrape the impurities on the top of the filter plate 34. The inside of the cleaning rod 36 is a hollow structure. A collecting door 29 is rotatably connected to one side of the cleaning rod 36 through a torsion spring. Under the action of the torsion spring, the bottom of the collecting door 29 can turn into the inside of the cleaning rod 36, and the scraped impurities can enter the inside of the cleaning rod 36 more smoothly for collection. A bottom plate 43 is rotatably connected to the bottom of the cleaning rod 36 through a torsion spring. One side of the bottom plate 43 can rotate towards the side close to the filter plate 34 under the action of the torsion spring. Under the restriction of the filter plate 34, the filter plate 34 can close the cleaning rod 36 and the torsion spring on the filter plate 34 is in a compressed state.
[0045] A collecting groove 44 is formed inside the filter plate 34. A baffle 42 is rotatably connected to the inside of the collecting groove 44 through a torsion spring. The baffle 42 can rotate downward under the action of the torsion spring. At the same time, the force of the torsion spring on the bottom plate 43 is greater than the force of the torsion spring on the baffle 42. So when the cleaning rod 36 rotates to the position of the baffle 42, the bottom plate 43 can push the baffle 42 to open, and the impurities collected inside the cleaning rod 36 can be discharged.
[0046] The bottom of the filter plate 34 is fixedly connected with a collection box 40. The collection box 40 can collect the impurities discharged by the cleaning rod 36. A maintenance plate 41 is arranged on the three-necked feed pipe 3. Through the maintenance plate 41, the staff can more smoothly clean the impurities inside the collection box 40, so that the cleaning of the filter plate 34 is more smooth, and to a certain extent, reduce the situation that impurities accumulate and adhere to the top of the filter plate 34 for a long time, resulting in a decrease in the speed of gas passing through the mesh holes of the filter plate 34, so that the staff can use the device more conveniently.
[0047] The material movement device includes a second motor 19. One side of the second motor 19 close to the pipeline 18 is fixedly connected to the surface of the pipeline 18. The second motor 19 is a forward and reverse motor. The output end of the second motor 19 rotates through one side of the pipeline 18 and extends into the interior of the second motor 19. The output end of the second motor 19 is fixedly connected with a auger 27 rotatably connected to the interior of the pipeline 18. By driving the auger 27 to rotate through the second motor 19, the catalyst inside the pipeline 18 can be discharged and moved more smoothly. Second universal balls 25 are arranged inside both the material holding cylinder 14 and the pipeline 18. A connecting hose 26 is arranged inside the second universal ball 25. Through the connecting hose 26, the interiors of the material holding cylinder 14 and the pipeline 18 are connected. The connecting hose 26 is a hose that can undergo a certain deformation. Through the connecting hose 26, the ineffective catalyst inside the material holding cylinder 14 can be discharged more smoothly. Second communicating pipes 21 and first communicating pipes 20 communicating with the interior of the pipeline 18 are arranged on the outer surface of the pipeline 18. Both the second communicating pipes 21 and the first communicating pipes 20 are closed by lids.
[0048] When the staff needs to discharge the ineffective catalyst, the first motor 4 and the second motor 19 are rotated. The first motor 4 rotates the material holding cylinder 14, and the catalyst inside the material holding cylinder 14 enters the interior of the pipeline 18 through the connecting hose 26. The second motor 19 drives the auger 27 to rotate, so that the auger 27 discharges the catalyst inside the pipeline 18 through the interiors of the first communicating pipe 20 and the second communicating pipe 21. When adding catalyst, the staff reversely rotates the second motor 19, and the staff pours the catalyst into the interior of the pipeline 18 through the first communicating pipe 20 or the second communicating pipe 21. Under the action of the auger 27, the catalyst enters the interior of the lower material holding cylinder 14 through the connecting hose 26, so that the addition and discharge of the catalyst inside the material holding cylinder 14 are more convenient, and at the same time, the staff can use the device more conveniently.
[0049] Inside the material storage cylinder 14, there is a transmission and agitation rod 45 rotatably connected and extending outside the material storage cylinder 14. Inside the limit rod 24, there is a transmission limit groove 48. On one side of the inner surface of the transmission limit groove 48, there are teeth. On the outer surface of the transmission and agitation rod 45, there is a stirring rod 46 fixedly connected. The transmission and agitation rod 45 drives the stirring rod 46 to rotate, enabling the stirring rod 46 to further agitate the catalyst inside the material storage cylinder 14 and making the contact between propane and the catalyst more comprehensive. On the outer surface of the transmission and agitation rod 45, there is a moving limit rod 49 fixedly connected. Inside the transmission limit groove 48, there is a transmission gear 47. The transmission gear 47 is meshed and connected to one side inside the limit rod 24 through the teeth. Inside the transmission gear 47, there is a third universal ball 50. The inside of the third universal ball 50 is slidably connected to the surface of the transmission and agitation rod 45. Inside the third universal ball 50, there is a limit groove slidably connected to the moving limit rod 49. Through the mutual cooperation of the moving limit rod 49 and the limit groove, the transmission and agitation rod 45 can rotate up and down and move inside the transmission gear 47. When the material storage cylinder 14 rotates obliquely, the transmission gear 47 rotates inside the transmission limit groove 48, enabling the transmission gear 47 to drive the transmission and agitation rod 45 to rotate, and the transmission and agitation rod 45 drives the stirring rod 46 to rotate, enabling the stirring rod 46 to further agitate the catalyst inside the material storage cylinder 14 and making the contact between the catalyst and propane more comprehensive, ensuring a certain reaction speed of propane and making full use of the catalyst.
[0050] Working principle: For the dehydrogenation reaction device, when in use, the first motor 4 is started by the staff. The first motor 4 drives the transmission shaft 9 to rotate. The transmission shaft 9 drives the two cams 17 to rotate. Due to the relative arrangement of the protruding ends of the two cams 17, the protruding ends of the cams 17 can push the material storage cylinder 14 to tilt around the rotation point of the first universal ball 13 during rotation, and the catalyst inside the material storage cylinder 14 shakes, increasing the contact area between the catalyst and the gas to a certain extent, thereby increasing the catalytic speed of the catalyst for the gas to a certain extent. The transmission shaft 9 can drive the transmission ring 12 to rotate around the power gear 15 inside the support ring 10 through the power gear 15, realizing the rotation of the material storage cylinder 14, enabling the catalyst inside the material storage cylinder 14 to be agitated, making the propane gas react more fully with the catalyst, and ensuring the propane dehydrogenation reaction speed to a certain extent.
[0051] When the first rotating shaft 5 rotates clockwise, through the inclined plane provided on the L-shaped positioning frame 31, when the first rotating shaft 5 rotates clockwise, it can push the L-shaped positioning frame 31 out of the inside of the fixed groove 30, so as to realize the single rotation of the first rotating shaft 5. When it is necessary to clean the filter plate 34, the first motor 4 drives the first rotating shaft 5 to rotate reversely. Under the action of the spring 32 on the L-shaped positioning frame 31, the first rotating shaft 5 drives the L-shaped positioning frame 31 to rotate through the fixed groove 30, so that the L-shaped positioning frame 31 drives the transmission plate 6 to rotate. The transmission plate 6 pushes the transmission roller 38 to rotate through the cleaning plate 7, and the transmission roller 38 drives the power transmission shaft 35 to rotate through the worm 39 and the worm gear 37. Since the force of the torsion spring on the bottom plate 43 is greater than the force of the torsion spring on the baffle 42, when the cleaning rod 36 rotates to the baffle 42, the bottom plate 43 can push the baffle 42 to open, and the impurities collected inside the cleaning rod 36 can be discharged;
[0052] Through the maintenance plate 41, the staff can clean the impurities inside the collection box 40 more smoothly, so that the cleaning of the filter plate 34 is more smooth, and to a certain extent, reduce the situation that impurities accumulate on the top of the filter plate 34 for a long time, resulting in the reduction of the gas passing speed through the mesh holes of the filter plate 34, so that the staff can use the device more conveniently;
[0053] When the staff needs to discharge the ineffective catalyst, the first motor 4 and the second motor 19 rotate. The first motor 4 rotates the material holding cylinder 14, and the catalyst inside the material holding cylinder 14 enters the inside of the pipeline 18 through the connecting hose 26. The second motor 19 drives the auger 27 to rotate, so that the auger 27 discharges the catalyst inside the pipeline 18 through the inside of the first communication pipeline 20 and the second communication pipeline 21. When it is necessary to add the catalyst, the staff makes the second motor 19 rotate reversely. The staff pours the catalyst into the inside of the pipeline 18 through the first communication pipeline 20 or the second communication pipeline 21. Under the action of the auger 27, the catalyst enters the inside of the lower material holding cylinder 14 through the connecting hose 26, so that the addition and discharge of the catalyst inside the material holding cylinder 14 are more convenient.
[0054] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
