[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The invention provides a turnover device for a benzene hydrogenation catalyst.

[0043] First embodiment:

[0044] Please combine Figure 1 , Figure 2 , Figure 7 and Figure 8 A turnover device for a benzene hydrogenation catalyst comprises a turnover tank 1, a carrier plate 8, a feed pipe 4 and an air intake assembly 6.

[0045] A curved pipe 2 is installed at the top axis of the turnover tank 1, a mounting plate 3 is fixedly provided at the top of the turnover tank 1 and on one side of the curved pipe 2, and a sealing assembly 5 is installed between the feed pipe 4 and the outside of the curved pipe 2;

[0046] The sealing assembly 5 includes a three-way pipe 53 installed at the end opposite to the bend pipe 2 and the feed pipe 4, the air intake assembly 6 includes a first air valve 61 installed at the top axis of the three-way pipe 53, the side wall of the three-way pipe 53 is fixedly connected with an air intake pipe 62, the outer wall of the air intake pipe 62 is installed with a second air valve 63, a second air bag 64 is fixedly provided at the inner top of the turnover tank 1 and located on one side of the bend pipe 2, an exhaust hole 65 is opened inside the turnover tank 1 and directly above the second air bag 64, a retaining ring 66 is fixedly provided on the inner wall of the exhaust hole 65, a sliding rod 67 is slidably connected to the inside of the retaining ring 66, a sealing rod 68 is fixedly provided at the top of the sliding rod 67, and an air outlet hole 69 is opened on the inner wall of the exhaust hole 65.

[0047] Combination Figure 7 : When the benzene hydrogenation catalyst feeding is completed, the user needs to first close the second valve body 22 to close the feed pipe 4 and cut off the connection between the main tank and the turnover tank 1. Then the user first rotates the first air valve 61 downward so that the upper end position of the three-way pipe 53 can be opened. After that, the second air valve 63 needs to be rotated to open the air inlet pipe 62. In this way, the air inlet pipe 62 can transport nitrogen to the three-way pipe 53, and then the nitrogen will push the residual benzene hydrogenation catalyst inside the three-way pipe 53 and the elbow 2 into the turnover tank 1.

[0048] Combination Figure 8 : Once too much nitrogen enters the turnover tank 1, it will definitely cause the air pressure in the turnover tank 1 to be too high. Once the internal air pressure is too high, the upward pressure will definitely resist and deflate the second air bag 64. Therefore, the deflated second air bag 64 will control its inner wall to resist the slide bar 67 and slide up along the retaining ring 66, which will drive the top blocking rod 68 to open the exhaust hole 65. Once the exhaust hole 65 is opened, the excess gas in the turnover tank 1 will enter the exhaust hole 65 from the outlet hole 69, and finally be discharged from the top of the exhaust hole 65.

[0049] The cross section of the blocking rod 68 is a conical structure that is wide at the top and narrow at the bottom, and one end of the air outlet 69 extends to the interior of the turnover tank 1.

[0050] It is understandable that: since the conical structure can ensure that when the internal air pressure of the turnover tank 1 is constant, the second airbag 64 will definitely expand to the initial state, and due to gravity, the blocking rod 68 will definitely fall due to its own weight, thereby timely sealing and closing the exhaust hole 65.

[0051] This embodiment: Compared with the traditional manual rotary exhaust working mode, in this case, during the process of nitrogen removal of residual benzene hydrogenation catalyst, the excess gas in the turnover tank 1 will push the compression degree of the second airbag 64 according to the pressure. If the pressure is high, the blocking rod 68 will rise a lot, and the exhaust hole 65 will be large. If the pressure is low, the blocking rod 68 will rise a little, and the exhaust hole 65 will be small. Therefore, such a design has the function of automatic exhaust, and can well ensure that the turnover tank 1 can be continuously stable in a good constant pressure environment, thereby ensuring the safety of the turnover tank 1 during transportation.

[0052] Second embodiment:

[0053] See also Figure 1 and Figure 6 The upper surface of the mounting plate 3 is respectively fixed with a first mounting frame 51 and a second mounting frame 52, the interior of the three-way pipe 53 is rotatably connected with an impeller 54, the axis of the impeller 54 and the external keyway extending to the three-way pipe 53 is connected with a contact plate 55, the upper surface of the mounting plate 3 and both sides of the contact plate 55 are installed with first airbags 56, the outer walls of the two first airbags 56 are sealed with hoses 57, the interiors of the first mounting frame 51 and the second mounting frame 52 are both installed with sealing rings 58, and the upper surface of the mounting plate 3 and one side of one of the first airbags 56 is fixed with a blocking plate 59;

[0054] A first valve body 21 is installed outside the curved pipe 2 , and a second valve body 22 is installed outside the feed pipe 4 .

[0055] Combination Figure 4 : When the feeding is in the initial state, the three-way pipe 53 connects the feeding pipe 4 and the elbow 2, so that the external main tank is connected to the turnover tank 1. At this time, the user needs to first rotate the first valve body 21 to open the elbow 2, and then rotate the second valve body 22 to open the feeding pipe 4.

[0056] Combination Figure 5 When the feed pipe 4 rapidly transports the benzene hydrogenation catalyst, the benzene hydrogenation catalyst in the flowing state will impact the impeller 54 to rotate. When the impeller 54 rotates, it will drive the resistance plate 55 to rotate. In this way, the two long ends of the resistance plate 55 can be controlled to quickly bear the force of the two first air bags 56. In this way, the two first air bags 56 are compressed to flush the internal gas into the sealing ring 58 through the two hoses 57. In this way, the sealing ring 58 will expand. The expansion of the sealing ring 58 can seal the joint of the three-way pipe 53.

[0057] The joints between the left and right ends of the three-way pipe 53 and the elbow 2 and the feed pipe 4 pass through the first mounting frame 51 and the second mounting frame 52 , and the inner walls of the two sealing rings 58 fit tightly with the two joints.

[0058] The bottom of the abutment plate 55 is rotatably connected to the upper surface of the mounting plate 3 , and the two hoses 57 are sealedly mounted to the outer walls of the two sealing rings 58 .

[0059] It is understandable that due to the setting of the blocking plate 59, the contact plate 55 will only rotate ninety degrees, which can ensure that the contact plate 55 continues to resist the two first airbags 56 and avoid the impeller 54 from continuously rotating, thereby causing the contact plate 55 to lose the resistance force on the first airbags 56.

[0060] This embodiment: Compared with the traditional design of directly installing the three-way pipe 53, this case adds a rotating impeller 54 to the traditional structure to drive the resistance plate 55 to the two first air bags 56, so that during the feeding process, it can be ensured that the sealing ring 58 can continue to seal the joints at both ends of the three-way pipe 53. Because the benzene hydrogenation catalyst is a dangerous item, this design can increase the sealing performance of the three-way pipe 53, thereby ensuring the safety and stability of the benzene hydrogenation catalyst during transportation and avoiding medium leakage.

[0061] Third embodiment:

[0062] See also Figure 3 , Fig. 9 and Fig.10A positioning plate 9 is fixedly provided on the top of the carrier plate 8, positioning rods 10 are fixedly provided on the upper surface of the carrier plate 8 and on both sides of the positioning plate 9, and a limiting ring 7 is fixedly provided on the outer wall of the turnover tank 1;

[0063] A truss 11 is fixedly provided on the top of the carrying plate 8 and on one side of the positioning plate 9, an inclined frame 12 is fixedly provided on the outer wall of the truss 11, and first rotating wheels 13 are rotatably connected to both sides of the inclined frame 12, a first cross bar 14 and a second cross bar 19 are fixedly provided inside the truss 11, two mounting seats 15 are fixedly provided on the outer wall of the first cross bar 14, and a clamp 20 is rotatably connected to the outside of the second cross bar 19, and connecting plates 16 are rotatably connected to the insides of the two mounting seats 15, and one end of the two connecting plates 16 is rotatably connected to a support frame 17, and second rotating wheels 18 are rotatably connected to both sides of the support frame 17.

[0064] Combination Figure 3 : In the process of placing the turnover tank 1 on the carrier plate 8, the user can first set up the bottom of the turnover tank 1 on the positioning plate 9, and during the setting process, the hole positions on the limit ring 7 and the two positioning rods 10 need to be checked and then inserted, so that the turnover tank 1 and the carrier plate 8 can be pre-positioned.

[0065] Combination Fig. 9 : When switching from the first embodiment to the second embodiment, when the user rotates the first air valve 61, the first air valve 61 will drive the spring rod 24 to move downward in the vertical direction of the limit sleeve 23 when it is drilled down, so that the bottom end of the spring rod 24 will enter the hole reserved in the outer wall of the turnover tank 1, so that the entire turnover tank 1 is stably locked with the carrying plate 8 and the truss 11.

[0066] from Figure 1 and Figure 3 It can be seen that at this time, the truss 11 is in an upright state, and the turnover tank 1 is upright, which makes it convenient for the user to feed materials into the turnover tank 1 .

[0067] Combination Fig.10 : The user needs to rotate the clamp 20 on the second cross bar 19 to separate it from the support frame 17. After the separation is completed, the two connecting plates 16 are rotated along the hinge of the mounting seat 15 to open. When the connecting plates 16 are opened, the support frame 17 needs to be rotated to adjust them to an upright state, so that the two connecting plates 16 will be positioned under the truss 11. Finally, the carrying plate 8 will switch from a horizontal state to an upright state, thereby laying down the entire turnover tank 1.

[0068] The top ends of the two positioning rods 10 extend to the inside of the limiting ring 7 , and the clamp 20 and the support frame 17 are clamped and matched with each other.

[0069] A limiting sleeve 23 is fixedly disposed on the outer wall of the second cross bar 19 and on one side of the fixture 20 . A spring rod 24 is slidably connected inside the limiting sleeve 23 . The top end of the spring rod 24 extends to the bottom of the first air valve 61 .

[0070] In this embodiment: during the process of switching from the feeding state to the nitrogen entry state, the spring rod 24 can be lowered to insert and lock the turnover tank 1, so that the turnover tank 1 can be more stable during the transportation process and the turnover tank 1 can be prevented from shaking and tilting. Secondly, the entire carrier plate 8 has two working states. When in the feeding state, the carrier plate 8 is placed horizontally to position and stabilize the turnover tank 1. In this way, the user can also push the truss 11 to transfer the turnover tank 1 under the empty tank. Once the turnover tank 1 is fully loaded, the entire carrier plate 8 needs to be switched to an upright state, so that the entire turnover tank 1 can be horizontally transferred by pushing the support frame 17, so that the fully loaded and heavy turnover tank 1 can be stably transferred.

[0071] Please refer to Figures 1 to 10 The working principle of the turnover device of a benzene hydrogenation catalyst provided by the present invention is as follows:

[0072] Step S1: Install the bottom of the turnover tank 1 on the positioning plate 9, and during the installation process, align the hole positions on the limit ring 7 and the two positioning rods 10 and then insert them, so that the turnover tank 1 and the carrier plate 8 can be pre-positioned.

[0073] Step S2: first rotate the first valve body 21 to open the bent pipe 2, and then rotate the second valve body 22 to open the feed pipe 4. When the feed pipe 4 quickly transports the benzene hydrogenation catalyst, the benzene hydrogenation catalyst in the flowing state will impact the impeller 54 to rotate. When the impeller 54 rotates, it will drive the resistance plate 55 to rotate, so that the two long ends of the resistance plate 55 can be controlled to quickly bear the force of the two first air bags 56. In this way, the compression of the two first air bags 56 will flush the internal gas into the sealing ring 58 through the two hoses 57, so that the sealing ring 58 will expand. The expansion of the sealing ring 58 can seal the joint of the three-way pipe 53.

[0074] Step S3: When the benzene hydrogenation catalyst is fed, the user needs to first close the second valve body 22 to close the feed pipe 4 and cut off the connection between the main tank and the turnover tank 1. Then, the user first rotates the first air valve 61 downward to open the upper end of the three-way pipe 53. Then, the second air valve 63 needs to be rotated to open the air inlet pipe 62. In this way, the air inlet pipe 62 can transport nitrogen to the three-way pipe 53. Then, the nitrogen will push the residual benzene hydrogenation catalyst inside the three-way pipe 53 and the elbow 2 into the turnover tank 1. Once the turnover tank 1 is When too much nitrogen enters the tank 1, it will definitely cause the air pressure in the turnover tank 1 to be too high. Once the internal air pressure is too high, the upward pressure will definitely resist and deflate the second airbag 64. Therefore, the deflated second airbag 64 will control its inner wall to resist the slide rod 67 and slide up along the retaining ring 66, which will drive the top blocking rod 68 to open the exhaust hole 65. Once the exhaust hole 65 is opened, the excess gas in the turnover tank 1 will enter the exhaust hole 65 from the outlet hole 69, and finally be discharged from the top of the exhaust hole 65.

[0075] Step S4: When the user rotates the first air valve 61, the first air valve 61 will drive the spring rod 24 to move downward in the vertical direction of the limit sleeve 23 when it is drilled and lowered, so that the bottom end of the spring rod 24 will enter the hole reserved on the outer wall of the turnover tank 1, so that the entire turnover tank 1 is stably locked with the carrier plate 8 and the truss 11, and then the clamp 20 is rotated on the second cross bar 19 to separate it from the support frame 17. After the separation is completed, the two connecting plates 16 are rotated along the hinge of the mounting seat 15 to open. When the connecting plates 16 are opened, the support frame 17 needs to be rotated to adjust it to an upright state, so that the two connecting plates 16 will be positioned below the truss 11, and finally the carrier plate 8 will switch from a horizontal state to an upright state, thereby laying down the entire turnover tank 1, and finally the support frame 17 is pushed to rotate the first rotating wheel 13 and the second rotating wheel 18 to transport the turnover tank 1.

[0076] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
