Description

Technical Field

[0001] This utility model relates to the field of magnetically stabilized bed technology, and in particular to a novel magnetically stabilized bed reactor. Background Technology

[0002] Trimeric triphthalic anhydride is an important basic chemical raw material used in the manufacture of polyester resins and polyimide resins, water-soluble polyester resins, water-soluble polyurethane resins, plasticizers and water-soluble amino alkyd resins, epoxy resin curing agents, as well as high-grade aviation lubricants, power capacitor impregnation oils, granular binders, sizing agents, smoke suppressants, instant binders, and TOTM, etc.

[0003] The concept of magnetically stabilized beds was first proposed by Filippov in the 1960s. In the late 1980s, the United States first achieved industrial-scale application of magnetically stabilized beds in the synthesis of ammonia and ethylene oxide. After decades of rapid development, magnetically stabilized beds have now been widely used in the fields of biochemical engineering and petrochemicals, demonstrating unique advantages. A magnetically stabilized bed is a special type of fluidized bed where magnetic particles align under the influence of an external magnetic field, forming a stable bed layer. It can be engineered like a fluidized bed without the concern of solid particles being carried away from the bed. Using a magnetically stabilized fluidized bed reactor can effectively suppress the loss of active catalyst components, reduce the difficulty and cost of catalyst separation, and is extremely advantageous for the heterogeneous oxidation synthesis of trimellitic anhydride.

[0004] The aforementioned devices have the following drawbacks. Currently, many magnetically stabilized bed reactors are fixed with bolts and screws, making it difficult to easily disassemble and replace internal components. This results in the need for personnel to use specialized tools to disassemble the internal parts when they are damaged, making the operation cumbersome and affecting maintenance efficiency. Therefore, a new type of magnetically stabilized bed reactor is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a novel magnetically stabilized bed reactor, comprising a reactor body 1, a cylindrical body 2, a conical end cap 31, an outlet pipe 32, and an inlet pipe 5. An adjustment mechanism 7 is provided on the cylindrical body 2, and an auxiliary mechanism 8 is provided on the conical end cap 31. The adjustment mechanism 7 includes an upper flange 71, which is rotatably connected to the outer side wall of the cylindrical body 2 via a bearing. The upper flange 71 is threadedly connected to the outer side wall of the reactor body 1. The upper flange 71 ensures that the cylindrical body 2 and the reactor body 1 are in close contact. A lower flange 72 is rotatably connected to the outer side wall of the cylindrical body 2 via a bearing, and a support 73 is fixedly connected to the outer side wall of the cylindrical body 2. An adjusting plate 74 is slidably connected to the inner front wall of the upper flange 71. A first compression spring 75 is fixedly connected to the outer top wall of the adjusting plate 74. The first compression spring 75 generates a continuous thrust on the adjusting plate 74. A plug rod 76 is fixedly connected to the outer bottom wall of the adjusting plate 74. The plug rod 76 cooperates with the bracket 73 to limit the rotation of the upper flange 71. A movable plate 77 is slidably connected to the inner front wall of the lower flange 72. A limit rod 78 is fixedly connected to the outer top wall of the movable plate 77. A second compression spring 79 is fixedly connected to the outer bottom wall of the movable plate 77. The second compression spring 79 generates a continuous thrust on the movable plate 77.

[0025] Reference Figures 2-4The upper flange 71 is threaded to the outer side wall of the reactor body 1, and the lower flange 72 is threaded to the outer side wall of the conical head 31. Wear-resistant pads are fixedly connected to the outer side walls of the insert rod 76 and the limiting rod 78, respectively. The wear-resistant pads increase the wear resistance of the surfaces of the insert rod 76 and the limiting rod 78. The insert rod 76 is snapped into the top inner wall of the support 73, and the limiting rod 78 is snapped into the bottom inner wall of the support 73. The limiting rod 78 and the support 73 cooperate with each other to limit the rotation of the lower flange 72. The top and bottom outer walls of the adjusting plate 74 and the movable plate 77 are fixedly connected with abrasive pads. The abrasive pads increase the surface wear resistance of the adjusting plate 74 and the movable plate 77. Friction is reduced to prevent slippage when gripping. The end of the first compression spring 75 away from the adjusting plate 74 is fixedly connected to the top inner wall of the upper flange 71. The end of the second compression spring 79 away from the movable plate 77 is fixedly connected to the bottom inner wall of the lower flange 72. The cylinder 2 is snapped onto the bottom outer wall of the reactor body 1. The conical head 31 is snapped onto the bottom outer wall of the cylinder 2. The liquid outlet pipe 32 is fixedly connected to the bottom outer wall of the conical head 31. An amide water inlet distribution pipe 4 is fixedly connected to the left outer wall of the conical head 31. An ear-type support 6 is fixedly connected to the side outer wall of the reactor body 1. The liquid inlet pipe 5 is fixedly connected to the top outer wall of the reactor body 1.

[0026] Reference Figures 3-4 The auxiliary mechanism 8 includes a semi-arc plate 81, which is fixedly connected to the bottom inner wall of the outlet pipe 32. A flange 82 is rotatably connected to the outer side wall of the outlet pipe 32 via a bearing. A sealing plate 83 is fixedly connected to the inner wall of the inner ring of the flange 82. A lever 84 is slidably connected to the bottom inner wall of the flange 82. A pin 85 is fixedly connected to the left outer wall of the lever 84. The pin 85 cooperates with the outlet pipe 32 to limit the rotation of the flange 82. A telescopic spring 86 is fixedly connected to the right outer wall of the lever 84. The pin 85 passes through the inner wall of the inner ring of the flange 82. The sealing plate 83 is slidably connected to the bottom outer wall of the semi-arc plate 81. The outer side wall of the flange 82 has a groove. The groove increases the roughness of the flange 82 surface, making it easier to rotate by equipment or manually. The end of the telescopic spring 86 away from the lever 84 is fixedly connected to the inner side wall of the flange 82. The telescopic spring 86 generates a continuous thrust on the lever 84.

[0027] Working principle: Pulling the adjusting plate 74 upwards moves the insert rod 76 upwards, separating it from the top inner wall of the support 73. Then, rotating the upper flange 71 separates it from the threaded connection on the side outer wall of the reactor body 1, separating the cylinder 2 from the reactor body 1. Simultaneously, pulling the movable plate 77 downwards moves the limiting rod 78, separating it from the support 73. Then, rotating the lower flange 72 separates it from the threaded connection on the side outer wall of the conical head 31, separating the cylinder 2 from the conical head 31. This allows personnel to easily access the internal components and inner wall for maintenance and inspection. During use, pulling the lever 84 moves the pin 85, separating it from the side inner wall of the outlet pipe 32. Then, rotating the flange 82 rotates the sealing plate 83, adjusting the size of the outward discharge port of the semi-arc plate 81. When the sealing plate 83 rotates to a certain angle, it seals the opening of the semi-arc plate 81, reducing the downward flow of liquid.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
