Description

Technical Field

[0001] This utility model relates to the field of membrane reactor technology, and in particular to a detachable membrane reactor. Background Technology

[0002] Membrane reactors are a new technology combining membrane processes and reaction processes. They integrate reaction and separation steps, offering several advantages: combining reaction and separation into a single unit process reduces the cost of separation processes; for reversible reactions, they overcome thermodynamic equilibrium limitations, removing products through membrane diffusion to achieve 100% conversion; and they allow for the adjustment of reaction parameters, mitigating reaction conditions, improving the selectivity and yield of the target product, and reducing side reactions. A membrane reactor consists of a mounting frame, an integrated plate, and a reaction membrane. The reaction membrane is often mounted inside the equipment via the mounting frame, and when changing the reaction membrane, the mounting frame usually needs to be removed from the equipment using the membrane reactor.

[0003] Chinese patent application CN202321973150.1 discloses a membrane reactor. The key technical points of this invention are: the membrane reactor provided is used for the carbon dioxide hydrogenation to olefins reaction. This membrane reactor can perform segmented temperature control to meet the optimal temperatures required for both the CO2 hydrogenation to methanol and methanol to olefins reactions, thereby maximizing the catalytic performance of the catalyst. Furthermore, the reactor does not require a cold trap, effectively reducing investment costs and energy consumption. Specifically, this invention utilizes a molecular sieve permeable membrane and a gas channel for purging gas to remove the byproduct H2O generated in both the CO2 to methanol and methanol to olefins reactions, shifting the reaction equilibrium to the right and increasing the CO2 conversion rate.

[0004] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: Membrane reactors consist of a mounting frame, an integrated plate, and a reaction membrane. The reaction membrane is often installed inside the equipment via the mounting frame. When replacing the reaction membrane, operators often need to remove the mounting frame from the equipment using the membrane reactor. After prolonged use, when a large amount of impurities accumulate on the reaction membrane, requiring cleaning or replacement, operators need to disassemble the mounting frame from the equipment to remove the entire reaction membrane. The connection between the mounting frame and the equipment is often quite robust, leading to operators needing to spend a significant amount of time using complex tools or resorting to force to remove the reaction membrane, thus increasing the workload for operators or damaging the mounting frame. Therefore, to address these issues, a detachable membrane reactor is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where workers need to disassemble the mounting bracket from the equipment to remove the entire reaction membrane. Since the connection between the mounting bracket and the equipment is often quite robust, workers need to spend a lot of time using complicated tools or resort to force to remove the reaction membrane, which increases the burden on workers or damages the mounting bracket. Therefore, this invention proposes a detachable membrane reactor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detachable membrane reactor, comprising a plurality of reaction membranes and an integrated plate, wherein one side of each of the plurality of reaction membranes is fixedly connected to the integrated plate, and a mounting frame is slidably connected to the surface of each of the plurality of reaction membranes. Disassembly and assembly devices are provided on both sides of the mounting frame, each device comprising two fixing rods, which are respectively fixedly connected to both sides of the mounting frame. An operating plate is slidably connected to the arc surface of each fixing rod, and an insertion rod is fixedly connected to one side of the operating plate. Insertion holes are provided on both sides of the integrated plate, and sliding holes are provided on both sides of the mounting frame.

[0007] The aforementioned components achieve the following effect: by setting up a disassembly and assembly device, the integrated plate and reaction membrane can be quickly disassembled from the mounting bracket. This avoids the situation where, after prolonged use, a large amount of impurities accumulate on the reaction membrane, requiring cleaning or replacement. In such cases, workers would need to disassemble the mounting bracket from the equipment to remove the reaction membrane as a whole. Since the connection between the mounting bracket and the equipment is often quite robust, workers would have to spend a lot of time using complicated tools or resort to force to remove the reaction membrane, thus increasing the burden on workers or damaging the mounting bracket. This improves the practicality of the device.

[0008] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the mounting bracket, and the size of the insertion rod is adapted to the size of the insertion hole.

[0009] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls it.

[0010] Preferably, a first spring is fitted onto the arc surface of the fixing rod, and the two ends of the first spring are fixedly connected to the operating plate and the mounting bracket, respectively.

[0011] The effect achieved by the above components is as follows: the first spring improves the stability of the insertion rod when it limits the integrated plate, and avoids the vibration generated by the operation of the equipment using the reaction membrane during operation, which would cause the operating plate to slide unintentionally on the arc surface of the fixed rod, thus causing the insertion rod to unintentionally release the limit on the integrated plate.

[0012] Preferably, both sides of the mounting bracket are fixedly connected with screws, and the arc surface of the screws is threadedly connected to a support plate.

[0013] The effect achieved by the above-mentioned components is to limit the operation panel, thereby preventing the insertion rod from repeatedly moving between the sliding hole and the insertion hole when the operator removes the integrated plate from the mounting bracket, which would otherwise affect the operator's ability to quickly remove the integrated plate and the reaction membrane.

[0014] Preferably, the mounting frame is provided with support devices on both sides. The support devices include two strip plates, which are slidably connected to the two sides of the mounting frame respectively. A connecting frame is fixedly connected to the surface of the strip plate, and a support block is fixedly connected to one side of the connecting frame. The surface of the support block is slidably connected to the mounting frame, and one side of the support block is slidably connected to an integral plate. Two L-shaped plates are fixedly connected to the surface of the strip plate. A drive rod is threaded into the L-shaped plate, and one end of the drive rod is rotatably connected to a connecting plate.

[0015] The effect achieved by the above components is as follows: by setting up a support device, the integrated plate is supported, thereby supporting the reaction membrane, so that the reaction membrane taken out of the equipment is suspended in the air, making it convenient to dry the residual liquid on the reaction membrane, thus improving the practicality of the device.

[0016] Preferably, an anti-slip pad is fixedly connected to the side of the connecting plate away from the drive rod, and the side of the anti-slip pad away from the connecting plate abuts against the mounting bracket.

[0017] The effect achieved by the above components is that the anti-slip pad increases the friction between the anti-slip pad and the mounting bracket, thereby improving the stability of the reaction membrane when it is supported.

[0018] Preferably, a positioning rod is fixedly connected to the side of the connecting plate near the drive rod, and the arc surface of the positioning rod is slidably connected to the L-shaped plate.

[0019] The effect achieved by the above components is that the positioning rod restricts the connecting plate from rotating with the drive rod, thereby increasing the stability when the anti-slip pad comes into contact with the mounting bracket.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] 1. In this utility model, by setting up a disassembly and assembly device, the integrated plate and reaction membrane can be quickly disassembled from the mounting frame. This avoids the situation where, after long-term use, a large amount of impurities appear on the reaction membrane, requiring cleaning or replacement. In such cases, the operator needs to disassemble the mounting frame from the equipment to remove the reaction membrane as a whole. However, the connection between the mounting frame and the equipment is often quite sturdy, which leads to the operator having to spend a lot of time using complicated tools or resorting to force to remove the reaction membrane. This increases the operator's burden or damages the mounting frame, thus improving the practicality of the device.

[0022] 2. In this utility model, by setting a support device, the integrated plate is supported, thereby supporting the reaction membrane, so that the reaction membrane taken out of the equipment is in a suspended state, which facilitates the drying of residual liquid on the reaction membrane and improves the practicality of the device.

[0029] Reference Figure 1As shown, this utility model provides a technical solution: a detachable membrane reactor, including several reaction membranes 1 and an integrated plate 2. One side of each of the reaction membranes 1 is fixedly connected to the integrated plate 2. A mounting frame 3 is slidably connected to the surface of each reaction membrane 1. Disassembly and assembly devices 4 are provided on both sides of the mounting frame 3. By setting the disassembly and assembly devices 4, the integrated plate 2 and the reaction membranes 1 can be quickly disassembled from the mounting frame 3. This avoids the situation where, after prolonged use, a large amount of impurities appear on the reaction membranes 1, requiring cleaning or replacement. In such cases, the operator would need to disassemble the mounting frame 3 from the equipment to remove the reaction membranes 1 as a whole. Since the connection between the mounting frame 3 and the equipment is often quite robust, operators would need to spend a lot of time using complicated tools or resort to force to remove the reaction membranes 1, thus increasing the operator's workload or damaging the mounting frame 3. This improves the practicality of the device. Supporting devices 5 are provided on both sides of the mounting frame 3. By setting the supporting devices 5, the integrated plate 2 is supported, thereby supporting the reaction membranes 1. This allows the reaction membranes 1 removed from the equipment to be suspended in the air, facilitating the drying of residual liquid on the reaction membranes 1, further improving the practicality of the device.

[0030] The following section will explain the specific setup and function of its disassembly / assembly device 4 and support device 5.

[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the disassembly and assembly device 4 includes two fixing rods 41, which are fixedly connected to both sides of the mounting frame 3 respectively. An operating plate 42 is slidably connected to the arc surface of the fixing rod 41. A plug rod 43 is fixedly connected to one side of the operating plate 42. Insertion holes 44 are provided on both sides of the integrated plate 2, and sliding holes 45 are provided on both sides of the mounting frame 3. A limit plate 46 is fixedly connected to the end of the fixing rod 41 away from the mounting frame 3. The size of the plug rod 43 matches the size of the insertion hole 44. When the operator pulls the operating plate 42, the operating plate 42 is positioned on the fixing rod 41. The operating plate 42 slides on the arc surface of the fixed rod 41. At this time, the limiting plate 46 achieves the effect of limiting the maximum sliding distance of the operating plate 42 on the arc surface of the fixed rod 41, avoiding the situation where the operating plate 42 will detach from the arc surface of the fixed rod 41 due to the large pulling force when the operator pulls it. The arc surface of the fixed rod 41 is fitted with a first spring 47. The two ends of the first spring 47 are fixedly connected to the operating plate 42 and the mounting bracket 3, respectively. When the operator releases the operating plate 42, the rebound force of the first spring 47 causes the operating plate 42 to slide on the arc surface of the fixed rod 41. The operating plate 42 drives the insertion rod 43 to move until the insertion rod 43 passes through the sliding hole 45 and inserts into the insertion hole 44. At this time, the first spring 47 improves the stability of the insertion rod 43 when it is limited to the integrated plate 2, avoiding the vibration generated by the operation of the equipment using the reaction membrane 1 during operation, which would cause the operating plate 42 to slide unintentionally on the arc surface of the fixed rod 41, thus causing the insertion rod 43 to be unintentionally released from the limit of the integrated plate 2. Both sides of the mounting bracket 3 are fixedly connected with screws 48, and the arc surface of the screws 48 is threadedly connected to the support plate 49. When the operator releases the support plate 49, the support plate 49 will be released from the limit of the integrated plate 2. After the insertion rod 43 limits the integrated plate 2, the operating plate 42 is continuously pulled until it moves to the highest point of the fixed rod 41. At this time, the support plate 49 is rotated so that it moves along the arc surface of the screw 48 until it moves below the operating plate 42. This achieves the effect of limiting the operating plate 42, preventing the insertion rod 43 from repeatedly moving between the sliding hole 45 and the insertion hole 44 when the operator removes the integrated plate 2 from the mounting bracket 3, which would otherwise affect the operator's ability to quickly remove the integrated plate 2 and the reaction membrane 1.

[0032] Reference Figure 4 and Figure 5As shown, specifically, the support device 5 includes two strip plates 53, which are slidably connected to both sides of the mounting frame 3. A connecting frame 52 is fixedly connected to the surface of the strip plate 53, and a support block 51 is fixedly connected to one side of the connecting frame 52. The surface of the support block 51 is slidably connected to the mounting frame 3, and one side of the support block 51 is slidably connected to the integral plate 2. Two L-shaped plates 54 are fixedly connected to the surface of the strip plate 53. A drive rod 55 is threaded into the L-shaped plate 54. A connecting plate 56 is rotatably connected to one end of the drive rod 55. An anti-slip pad 57 is fixedly connected to the side of the connecting plate 56 away from the drive rod 55. The side of the anti-slip pad 57 away from the connecting plate 56 abuts against the mounting frame 3. When the operator rotates the drive rod 55, the drive rod 55 moves within the thread of the L-shaped plate 54, simultaneously driving... Rod 55 drives connecting plate 56 to move, connecting plate 56 drives anti-slip pad 57 to move until anti-slip pad 57 comes into contact with the surface of mounting bracket 3. At this time, anti-slip pad 57 achieves the effect of increasing friction between it and mounting bracket 3, so as to improve the stability of supporting reaction membrane 1. A positioning rod 58 is fixedly connected to the side of connecting plate 56 near drive rod 55. The arc surface of positioning rod 58 is slidably connected to L-shaped plate 54. When the operator rotates drive rod 55, drive rod 55 moves in the threaded movement of L-shaped plate 54. At the same time, drive rod 55 drives connecting plate 56 to move, connecting plate 56 drives positioning rod 58 to slide in L-shaped plate 54. At this time, positioning rod 58 achieves the effect of limiting connecting plate 56 to rotate with drive rod 55, so as to increase the stability of anti-slip pad 57 when it comes into contact with mounting bracket 3.

[0033] Working principle: When the operator needs to remove the reaction membrane 1 and the integrated plate 2 from the mounting bracket 3 installed in the equipment, the operating plate 42 is pulled, causing it to slide on the arc surface of the fixed rod 41. The first spring 47 is stretched, and the operating plate 42 simultaneously drives the insertion rod 43 to move until the insertion rod 43 disengages from the insertion hole 44. At this point, the operating plate 42 is pulled again, causing it to slide on the sliding hole 45 until the operating plate 42 moves to the highest point of the fixed rod 41. Then, the support plate 49 is rotated, causing it to move along the threaded surface of the screw 48 until it moves below the operating plate 42. Finally, the integrated plate 2 is pulled, causing it to move within the mounting bracket 3. Slide the integrated plate 2 until it detaches from the mounting bracket 3. At the same time, the integrated plate 2 drives the reaction membrane 1 upward until the reaction membrane 1 and the integrated plate 2 are completely removed. This achieves the effect of quickly removing the integrated plate 2 and the reaction membrane 1 from the mounting bracket 3. This avoids the situation where, after long-term use, a large amount of impurities appear on the reaction membrane 1, requiring cleaning or replacement. In such cases, the operator would need to remove the mounting bracket 3 from the equipment to remove the reaction membrane 1 as a whole. The connection between the mounting bracket 3 and the equipment is often quite strong, which would require the operator to spend a lot of time using complicated tools or even resort to force to remove the reaction membrane 1. This would increase the operator's workload or damage the mounting bracket 3, thus improving the practicality of the device.

[0034] When the staff needs to remove the reaction membrane 1 and the integrated plate 2 from the mounting bracket 3 installed in the equipment, the integrated plate 2 and the reaction membrane 1 can be raised to allow them to air dry in advance. At this time, the drive rod 55 is rotated, causing it to move threadedly within the L-shaped plate 54. Simultaneously, the drive rod 55 drives the connecting plate 56 to move, and the connecting plate 56 drives the positioning rod 58 to slide within the L-shaped plate 54. At the same time, the connecting plate 56 drives the anti-slip pad 57 to move until the anti-slip pad 57 no longer abuts against one side of the mounting bracket 3. Then, the strip plate 53 is pulled upwards, and the strip plate 53 slides upwards on the surface of the mounting bracket 3. Simultaneously, the strip plate 53 drives the connecting bracket 52 to move upwards, and the connecting bracket 52 drives the support block 51 to slide upwards within the mounting bracket 3. The support block 51 supports the integrated plate 2 and moves it upward. The integrated plate 2 drives the reaction membrane 1 upward until the reaction membrane 1 is raised to a certain height. At this time, the drive rod 55 is rotated again, causing the drive rod 55 to move threadedly within the L-shaped plate 54. At the same time, the drive rod 55 drives the connecting plate 56 to move. The connecting plate 56 drives the positioning rod 58 to slide within the L-shaped plate 54. Simultaneously, the connecting plate 56 drives the anti-slip pad 57 to move until the anti-slip pad 57 abuts against one side of the mounting frame 3 again. At this time, the integrated plate 2 is supported, thereby supporting the reaction membrane 1. This allows the reaction membrane 1, which is removed from the equipment, to be suspended in the air, facilitating the drying of residual liquid on the reaction membrane 1 and improving the practicality of the device.
