Description

Technical Field

[0001] This utility model relates to the field of gas membrane separation technology, specifically an assembled gas membrane separation device. Background Technology

[0002] Gas membrane separation devices are highly efficient gas separation equipment with a modular design. Their core function is to separate different gas components through selective permeation membranes. Gas membrane separation devices generally consist of membrane elements, a housing, and end caps. To facilitate cleaning or replacement of the membrane elements, they are often designed as modular units. However, the sealing structure is fixed using bolts and other methods, making disassembly time-consuming and labor-intensive. Furthermore, the membrane elements are located inside the device and are not easily extracted, presenting certain drawbacks. Therefore, we propose a modular gas membrane separation device. Utility Model Content

[0004] Therefore, the technical solution adopted by this utility model is as follows: an assembled gas membrane separation device, including a separation cylinder, a lower end plate, an upper end plate, a membrane element, an ejection assembly, and a quick-release assembly. The lower end plate is screwed to the bottom of the separation cylinder, the upper end plate is arranged on the top of the separation cylinder, the membrane element is inserted inside the separation cylinder, and a sealing ring and a first metal ring are respectively arranged on the top and bottom of the membrane element. The ejection assembly includes a second metal ring inserted in the lower end plate, a sealing ring arranged outside the second metal ring, a first spring arranged at the bottom of the second metal ring, and a fixing block arranged at the bottom of the first spring. The quick-release assembly includes a fixing seat arranged outside the separation cylinder, a fastening rod threaded to the fixing seat, a fixing plate bearing connected to the bottom of the fastening rod, a second spring arranged at the bottom of the fixing plate, and an abutment block arranged at the bottom of the second spring.

[0005] Preferably, the outer side of the separation cylinder is provided with a permeable gas discharge pipe, and the top of the separation cylinder is provided with a number of positioning posts.

[0006] Preferably, the bottom of the lower end plate is provided with an impermeable gas discharge pipe, and the top of the lower end plate is provided with a mounting groove for installing the pop-out component.

[0007] Preferably, the top of the upper end plate is provided with a gas inlet pipe, and the upper end plate is provided with a number of positioning holes.

[0008] Preferably, the first spring and the connected fixing block form a group, and a total of four groups are provided.

[0009] Preferably, the fixing seat is threadedly connected to a fastening knob, and the fastening knob is in abutting connection with the outer side of the fastening rod.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The fastening rod of the quick-release assembly can rotate, thereby driving the fixing plate, the second spring and the abutment block to move upward, so that the abutment block can be separated from the upper end plate, and the upper end plate can be directly disassembled, saving the trouble of disassembling the bolts. The first spring of the pop-out assembly has a certain elastic potential energy, which allows the second metal ring and the sealing ring to push the membrane element upward so that the membrane element can be directly pulled out, achieving the effect of quick-release of the membrane element, saving time and effort. At the same time, the sealing ring abuts against the membrane element, which can improve the sealing performance of the bottom of the membrane element, and the sealing ring can improve the sealing performance of the top of the membrane element, so that the separation is more thorough.

[0025] Example 1:

[0026] Reference Figure 1-5 This is the first embodiment of the present invention. This embodiment provides an assembled gas membrane separation device, including a separation cylinder 100, a lower end plate 200, an upper end plate 300, a membrane element 400, an ejection assembly 500, and a quick-release assembly 600.

[0027] Specifically, a permeate discharge pipe 101 is provided on the outer side of the separation cylinder 100, and a number of positioning posts 102 are provided on the top of the separation cylinder 100. In use, the gas passing through the membrane element 400 can be discharged through the permeate discharge pipe 101 for separation, and the positioning posts 102 can be used in conjunction with the positioning holes 302 for the installation of the upper end plate 300.

[0028] Specifically, the lower end plate 200 is screwed to the bottom of the separation cylinder 100. The bottom of the lower end plate 200 is provided with an unpermeable gas discharge pipe 201, and the top of the lower end plate 200 is provided with a mounting groove 202 for installing the ejector assembly 500. In use, the lower end plate 200 can seal the separation cylinder 100, and the unpermeable gas discharge pipe 201 can discharge the gas that has not passed through the membrane element 400 for separation. At the same time, the mounting groove 202 facilitates the installation of the ejector assembly 500.

[0029] Specifically, the upper end plate 300 is arranged on the top of the separation cylinder 100. The top of the upper end plate 300 is provided with a gas inlet pipe 301, and the upper end plate 300 is provided with several positioning holes 302. In use, the upper end plate 300 can seal the separation cylinder 100, and the gas inlet pipe 301 can deliver gas into the separation cylinder 100 for separation. The several positioning holes 302 can be aligned with the positioning posts 102 and inserted to install the upper end plate 300 on the top of the separation cylinder 100.

[0030] Specifically, the membrane element 400 is inserted inside the separation cylinder 100. The top and bottom of the membrane element 400 are respectively provided with a sealing ring 401 and a first metal ring 402. In use, gas can be separated through the membrane element 400. The sealing ring 401 can improve the sealing of the top of the membrane element 400, and the first metal ring 402 can improve the hardness of the bottom of the membrane element 400 so that the ejector assembly 500 can eject the membrane element 400.

[0031] Specifically, the pop-out assembly 500 includes a second metal ring 503 inserted within the lower end plate 200, a sealing ring 504 disposed outside the second metal ring 503, a first spring 502 disposed at the bottom of the second metal ring 503, and a fixing block 501 disposed at the bottom of the first spring 502. The first spring 502 and the connected fixing block 501 form a group, and a total of four groups are provided. In use, the elasticity of the first spring 502 allows the second metal ring 503 and the sealing ring 504 to pop out the membrane element 400, so as to quickly disassemble the membrane element 400. The sealing ring 504 can improve the sealing performance of the bottom of the membrane element 400.

[0032] Specifically, the quick-release assembly 600 includes a fixed base 601 disposed on the outside of the separation cylinder 100, a fastening rod 602 threadedly connected to the fixed base 601, a fixed plate 603 with a bearing connected to the bottom of the fastening rod 602, a second spring 604 disposed on the bottom of the fixed plate 603, and an abutment block 605 disposed on the bottom of the second spring 604. A fastening knob 606 is threadedly connected to the fixed base 601, and the fastening knob 606 abuts against the outside of the fastening rod 602. In use, rotating the fastening rod 602 can drive the fixed plate 603, the second spring 604, and the abutment block 605 to move up and down. When the moving abutment block 605 disengages from the upper end plate 300, the upper end plate 300 can be quickly disassembled. When the moving abutment block 605 abuts against the upper end plate 300, the upper end plate 300 can be quickly fixed for use.

[0033] The working principle and usage process of this utility model are as follows: In use, the fastening rod 602 of the quick-release assembly 600 can be rotated outward. The rotating fastening rod 602 can drive the fixing plate 603, the second spring 604 and the abutment block 605 to move upward until the abutment block 605 is completely separated from the upper end plate 300. Then, the upper end plate 300 is moved to separate from the separation cylinder 100. At the moment of separation, the first spring 502 of the pop-out assembly 500 can push out the membrane element 400. After being pushed out, it can be pulled out directly to quickly disassemble the membrane element 400. During sealing, the first spring 502 of the pop-out assembly 500 can apply external force to the second metal ring 503 and the sealing ring 504. After application, the sealing ring 504 is pressed tightly against the first metal ring 402 at the bottom of the membrane element 400. Then, the sealing ring 401 is pressed tightly against the top of the membrane element 400 to seal.
