Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, and in particular relates to a continuous flow microchannel reactor. Background Technology

[0002] Continuous flow microchannel reactors are continuous flow chemical reaction devices manufactured using precision machining technology, containing micron-sized channels (characteristic dimensions typically ranging from 10 to 1000 micrometers). With their superior mass and heat transfer performance, intrinsic safety, precise process control, excellent repeatability, and simplified scale-up strategies, they have become a powerful tool in modern chemical engineering and synthetic chemistry. Their enormous potential in improving reaction efficiency, safety, product quality, and promoting green and sustainable chemical production has been widely recognized. With continuous technological advancements and declining costs, microreactor technology will undoubtedly play an increasingly important role in future chemical manufacturing, becoming one of the key technologies for achieving efficient, safe, green, and intelligent chemical production.

[0003] A search revealed a microchannel reactor disclosed in publication number CN209917850U, filed on April 19, 2019. Multiple reaction tubes are connected to a shell and penetrate the heat exchange chamber of the shell. A first connecting mechanism has a first connecting channel corresponding to a first opening of the reaction tube, and a second connecting mechanism has a second connecting channel corresponding to a second opening of the reaction tube. The first and second connecting channels allow at least two of the multiple reaction tubes to be sequentially connected, forming a reaction channel for the flow of reactants. This extends the length of the reaction channel without changing the shell length, saving space, reducing equipment costs, and further extending the residence time of the reaction medium.

[0004] However, it still has the following drawbacks in practical use:

[0005] Most existing continuous flow microchannel reactors are fixed with bolts during use. This method is cumbersome, time-consuming, labor-intensive, and inefficient when workers disassemble and repair them.

[0006] 2. Existing continuous flow microchannel reactors cannot be quickly flushed after use, which affects the normal operation of subsequent reactors. Therefore, we provide a continuous flow microchannel reactor to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a continuous flow microchannel reactor. By setting up installation components, it is easy for operators to quickly disassemble and assemble the shell, saving time and effort and increasing work efficiency. Furthermore, by using a backwashing component, the reaction tubes in the shell can be flushed, improving the flushing efficiency of the reaction tubes in the shell and ensuring the normal use of the shell.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a continuous flow microchannel reactor, including a worktable and a shell set directly above it. Both ends of the outer wall of the shell are provided with mounting seats. A rotating groove is opened on the top of the front end face of the mounting seat. An installation component is provided inside the rotating groove. A backwashing component is provided on one side of the shell.

[0010] The mounting components include a push block installed inside the rotary slot and a rotating frame fixed to the inner wall of the push block;

[0011] The backwashing assembly includes a water tank located on one side of the workbench and a water pump installed at one end of the water tank.

[0012] The present invention is further configured such that a mounting bracket is installed at the rear end of the upper surface of the workbench, a controller is installed inside the upper part of the mounting bracket, and a heat exchange medium cylinder is installed on the top of the mounting bracket.

[0013] The present invention is further configured such that a medium inlet and a medium outlet are respectively provided at the top two ends of the shell, and a feed inlet and a discharge outlet are respectively provided at the two ends of the shell.

[0014] The present invention is further configured such that a flip cover is rotatably mounted on the top of the mounting base, and a slot is provided at the bottom front end of the flip cover.

[0015] The present invention is further configured such that a rotating shaft is rotatably mounted at the inner center of the rotating frame, and a torsion spring is sleeved on the middle of the outer wall of the rotating shaft.

[0016] The present invention is further configured such that both ends of the rotating shaft are fixed on the inner wall of the rotating groove, and a card plate is fixed on the top of the rotating frame.

[0017] The present invention is further configured such that a water outlet pipe is provided at the bottom of one side wall of the water tank, and the other end of the water outlet pipe is connected to the water inlet of the water pump through a pipe joint.

[0018] The present invention is further configured such that the outlet end of the water pump is connected to the connecting pipe via a pipe joint, and the other end of the connecting pipe is connected to the connecting pipe via a pipe joint.

[0019] This utility model has the following beneficial effects:

[0020] This invention, by setting up an installation component, allows the card plate to rotate around the pivot point under the elastic action of a torsion spring, thereby achieving or releasing the limiting effect between the card plate and the slot. This facilitates quick assembly and disassembly of the shell by the operator, saving time and effort and increasing work efficiency. It solves the problem that existing continuous flow microchannel reactors mostly rely on bolts to fix the reactor during use, which is cumbersome, time-consuming, labor-intensive, and inefficient for the operator during disassembly and maintenance.

[0021] This invention, by setting up a backwashing component, uses a water pump to draw water in the reverse direction and flow it into the reaction tube inside the shell, which can flush the reaction tube inside the shell, improve the flushing efficiency of the reaction tube inside the shell, and ensure the normal use of the shell. It solves the problem that existing continuous flow microchannel reactors cannot quickly flush the internal reaction tube after use, which will affect the normal use of subsequent reactors.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0031] Please see Figures 1 to 4 This utility model is a continuous flow microchannel reactor, including a worktable 100 and a shell 104 disposed directly above it. Both ends of the outer wall of the shell 104 are provided with mounting seats 105. The top of the front end face of the mounting seat 105 is provided with a rotating groove 105b. The interior of the rotating groove 105b is provided with a mounting assembly 200. The mounting assembly 200 includes a push block 201 installed inside the rotating groove 105b and a rotating frame 202 fixed on the inner wall of the push block 201.

[0032] Specifically, a mounting bracket 101 is installed at the rear end of the upper surface of the workbench 100, a controller 102 is installed inside the upper part of the mounting bracket 101, and a heat exchange medium cylinder 103 is installed on the top of the mounting bracket 101; a medium inlet 104a and a medium outlet 104b are respectively provided at the top two ends of the shell 104, and a feed inlet 104c and a discharge outlet 104d are respectively provided at the two ends of the shell 104; a flip cover 105a is rotatably installed on the top of the mounting base 105, and a slot 105c is provided at the bottom front end of the flip cover 105a; a rotating shaft 203 is rotatably installed at the center of the interior of the rotating frame 202, and a torsion spring 204 is sleeved in the middle of the outer wall of the rotating shaft 203; the two ends of the rotating shaft 203 are respectively fixed on the inner wall of the rotating groove 105b, and a clamping plate 205 is fixed on the top of the rotating frame 202.

[0033] Furthermore, the shell 104 is the main body of the reactor, which is existing technology and will not be described in detail here. The cross-section of the rotating groove 105b is T-shaped with the top and bottom facing each other. The rotating frame 202 rotates around the rotating shaft 203 as the center under force. The controller 102, heat exchange medium cylinder 103, etc. are all existing technologies and will not be described in detail here. The cross-section of the slot 105c is L-shaped with the top and bottom facing each other. Under the elastic action of the torsion spring 204, the position of the slot plate 205 can be rotated and adjusted.

[0034] The operation process of this embodiment is as follows: When the housing 104 needs to be installed, force is applied to the push block 201 to push it into the rotating groove 105b. When the push block 201 moves, it will drive the rotating frame 202 to rotate around the rotating shaft 203 and squeeze the torsion spring 204. At this time, the locking plate 205 at the top of the rotating frame 202 will rotate outward and move out of the locking groove 105c, releasing the limiting effect between the locking plate 205 and the locking groove 105c. Then, rotate the flip cover 105a upward and place the housing 104 inside the mounting base 105. Then, release the push block 201. Under the elastic action of the torsion spring 204, the locking plate 205 will spring into the locking groove 105c, which will play a limiting role. The same principle applies when disassembling, which makes it easier for workers to quickly disassemble and assemble the housing 104, saving time and effort and increasing work efficiency. Example 2

[0035] Please see Figure 1 and Figure 5 Based on Example 1, the difference from the first example is that a backwashing assembly 300 is provided. The backwashing assembly 300 includes a water tank 301 disposed on one side of the workbench 100 and a water pump 302 installed at one end of the water tank 301. This solves the problem that existing continuous flow microchannel reactors cannot quickly flush the internal reaction tubes after use, which would affect the normal use of subsequent reactors.

[0036] Specifically, a water outlet pipe 301a is provided at the bottom of one side wall of the water tank 301. The other end of the water outlet pipe 301a is connected to the water inlet of the water pump 302 through a pipe joint. The water outlet of the water pump 302 is connected to the connecting pipe 302a through a pipe joint. The other end of the connecting pipe 302a is connected to the connecting pipe 303 through a pipe joint.

[0037] Furthermore, the pipe fitting serves as a pipe connection, and the butt joint 303 can be quickly inserted into the discharge port 104d to achieve reverse flushing operation.

[0038] The operation process of this embodiment is as follows: After the shell 104 is installed, the material is introduced into the reaction tube inside the shell 104. Then, the medium in the heat exchange medium cylinder 103 is continuously circulated through the medium inlet 104a and the medium outlet 104b to realize the reaction treatment of the material. After the microchannel reactor is used, the water pump 302 is started. The water pump 302 runs through the water outlet pipe 301a to draw out the cleaning water in the water tank 301. Then, the water flow is reversed from the outlet 104d into the shell 104 under the action of the connecting pipe 302a and the connecting pipe 303, thereby flushing the reaction tube in the shell 104, improving the flushing efficiency of the reaction tube in the shell 104, and ensuring the normal use of the shell 104.
