Description

Technical Field

[0001] This utility model relates to the field of tubular reactor technology, and in particular to a tubular reactor that is easy to disassemble and maintain. Background Technology

[0002] A tubular reactor is a type of chemical reactor shaped like a tube. In a tubular reactor, reactants typically flow continuously through the tubes, and the chemical reaction takes place inside the tubes. Tubular reactors have a high length-to-diameter ratio (the ratio of the tube length to its diameter), which allows the reactants sufficient residence time within the tubes to complete the reaction.

[0003] In existing technologies, many tubular reactors are designed as a single unit. For example, there is no convenient separation structure between the tube body and various internal components (such as packing and stirring devices). This makes it difficult to separate the tube body from the internal components when maintenance or replacement is required. When a tubular reactor malfunctions, complex disassembly operations, such as cutting and destructive disassembly, are required, making the operation quite inconvenient.

[0004] To improve upon this design, a tubular reactor that is easy to disassemble and maintain is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tubular reactor that is easy to disassemble and maintain.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tubular reactor that is easy to disassemble and maintain includes a tube body, an installation groove at one end of the tube body, an installation plate inside the installation groove, multiple openings on the installation plate, a T-shaped insert rod slidably passing through the tube body via an external elastic mechanism, a slot on the installation plate, a rotating shaft on the installation plate via a rotating groove, multiple blades mounted on the rotating shaft, a hidden groove on the arc-shaped outer wall of the installation plate, a through-frame extending into the rotating groove slidably passing through the hidden groove via an internal elastic mechanism, an annular groove on the rotating shaft, a connecting shaft rotatably mounted on the rotating shaft, and two intercepting nets on the connecting shaft via a limiting mechanism.

[0008] Preferably, the external elastic mechanism includes an external spring sleeved on the outside of the T-shaped insert, with both ends of the external spring elastically connected to the outer wall of the tube body and the outer wall of the head of the T-shaped insert, respectively.

[0009] Preferably, the internal elastic mechanism includes an internal spring sleeved on the outside of the through frame, with both ends of the internal spring elastically connected to the outer wall of the branch portion of the through frame and the inner wall of the hidden groove.

[0010] Preferably, the limiting mechanism includes a limiting block installed on the interception net, and the inner wall of the tube is provided with a limiting groove corresponding to the limiting block.

[0011] Preferably, the plurality of openings are distributed at equal intervals along the circumference of the mounting plate, and the plurality of blades are distributed at equal intervals along the circumference of the rotation axis.

[0012] The beneficial effects of this utility model are:

[0013] 1. The installation and removal of the mounting plate on the tube body can be easily achieved through the external elastic mechanism composed of the T-shaped plug and the external spring. When maintenance is required, simply drag the T-shaped plug to overcome the elastic potential energy of the external spring to remove the mounting plate from the tube body. The operation is simple and quick.

[0014] 2. When the mounting plate moves away from the mounting groove of the pipe body, the through bracket in the hidden groove is automatically pushed out by the internal spring and disengaged from the annular groove on the rotating shaft, which further facilitates the disassembly of the internal components of the pipe body and improves maintenance efficiency.

[0015] 3. The blades on the rotating shaft on the mounting plate will be impacted and rotated when the object enters the tube, which will agitate and mix the object, promote the reaction, and improve the reaction efficiency and quality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A tubular reactor, easy to disassemble and maintain, includes a tube body 1. An installation groove 2 is provided at one end of the tube body 1, and an installation plate 3 is provided within the installation groove 2. The installation plate 3 has multiple openings 4. A T-shaped insert 11 is slidably inserted through the tube body 1 via an external elastic mechanism. The installation plate 3 has a slot 13, and a rotating shaft 7 is provided on the installation plate 3 via a rotating groove 14. Multiple blades 8 are mounted on the rotating shaft 7. A hidden groove 16 is provided on the arc-shaped outer wall of the installation plate 3. A through-frame 17 extending into the rotating groove 14 is slidably inserted through the hidden groove 16 via an internal elastic mechanism. The rotating shaft 7 has an annular groove 15, and a connecting shaft 5 is rotatably mounted on the rotating shaft 7.

[0023] Two intercepting nets 6 are provided on the connecting shaft 5 via a limiting mechanism. The space between the two intercepting nets 6 can be filled with fillers of various shapes, such as Raschig rings and Pall rings.

[0024] The external elastic mechanism includes an outer spring 12 sleeved on the outside of the T-shaped insert 11. Both ends of the outer spring 12 are elastically connected to the outer wall of the tube body 1 and the outer wall of the head of the T-shaped insert 11, respectively. The elastic potential energy provided by the outer spring 12 allows the T-shaped insert 11 to be dragged, ensuring its tail is within the slot 13. In this state, the mounting plate 3 can be stably installed within the mounting groove 2. Correspondingly, dragging the T-shaped insert 11 allows for the installation and removal of the mounting plate 3, thereby enabling the disassembly of the mounting plate 3 along the tube body 1.

[0025] The internal elastic mechanism includes an inner spring 18 sleeved on the outside of the through frame 17. The two ends of the inner spring 18 are elastically connected to the outer wall of the branch portion of the through frame 17 and the inner wall of the hidden groove 16, respectively. The elastic potential energy provided by the outer spring 12 can push the through frame 17. After the mounting plate 3 moves away from the mounting groove 2, the end of the through frame 17 loses the compression of the inner wall of the mounting groove 2. At this time, the through frame 17 can be pushed out of the hidden groove 16 by the inner spring 18, so its other end will disengage from the annular groove 15.

[0026] The limiting mechanism includes a limiting block 10 installed on the intercepting net 6, and a limiting groove 9 corresponding to the limiting block 10 is provided on the inner wall of the tube body 1. The limiting block 10 and the limiting groove 9 can prevent the intercepting net 6 from rotating with the rotating shaft 7 inside the tube body 1.

[0027] Multiple openings 4 are evenly spaced along the circumference of the mounting plate 3, and multiple blades 8 are evenly spaced along the circumference of the rotation axis 7. The openings 4 facilitate the entry of objects into the tube 1, and the blades 8 can rotate after the objects enter, thereby agitating and mixing the objects.

[0028] The surfaces of the through-frame 17 and the annular groove 15 that come into contact with each other are all polished, as are the surfaces of the rotating shaft 7 and the rotating groove 14 that come into contact with each other. This polishing process ensures smoothness and guarantees smooth rotation between multiple components and other operations.

[0029] In use, the mounting plate 3 is installed in the mounting groove 2 at the end of the pipe body 1. Multiple blades 8 are mounted on the rotating shaft 7 of the mounting plate 3. A connecting shaft 5 is rotatably mounted on the rotating shaft 7, and two intercepting nets 6 are mounted on the connecting shaft 5. The space between the two intercepting nets 6 is filled with filler (such as Raschig rings, Pall rings, etc.). When an object enters the pipe body 1 through the multiple openings 4 on the mounting plate 3, it impacts the blades 8, causing the blades 8 to drive the rotating shaft 7 to rotate. The blades 8 agitate and mix the entering object, promoting the reaction.

[0030] When the tubular reactor needs to be disassembled and maintained, dragging the T-shaped insert 11 overcomes the elastic potential energy of the outer spring 12, causing the tail of the T-shaped insert 11 to move out of the slot 13. At this time, the installation and release operation of the mounting plate 3 can be realized, thereby removing the mounting plate 3 from the tube body 1. As the mounting plate 3 moves away from the mounting slot 2, the end of the through-frame 17 in the hidden slot 16 loses the compression of the inner wall of the mounting slot 2. At this time, the through-frame 17 is pushed out of the hidden slot 16 under the elastic potential energy of the inner spring 18 sleeved on it. The other end of the through-frame 17 will disengage from the annular groove 15 on the rotating shaft 7. This makes it convenient to maintain and replace the internal components of the tube body 1 (such as the blades 8, rotating shaft 7, intercepting net 6, and packing).

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
