Description

Technical Field

[0001] The utility model relates to the technical field of membrane separators, in particular to a casing-type pervaporation membrane separator. Background Art

[0002] Membrane separators utilize natural or synthetic polymer membranes, driven by external energy or chemical potential differences, to separate, grade, purify, and enrich binary or multi-component solutes and solvents. The principle of pervaporation is to create a chemical potential difference between the upstream and downstream sides of the pervaporation membrane by drawing a vacuum downstream of the membrane. The permeable gaseous component upstream of the membrane passes through the membrane surface and into the downstream side, achieving efficient and energy-efficient separation of the permeable and less permeable components. Pervaporation is commonly used to separate organic solvents from water. Coupling it with distillation towers, heat pumps, and other technologies can significantly reduce separation costs.

[0003] The flanges on the heads at both ends of the membrane device are fixed to the flanges of the membrane device cylinder by bolts. However, due to the limited life of the membrane tubes in the membrane device, the heads at both ends of the membrane device need to be disassembled regularly to replace the membrane tubes. The flanges and bolts located on the outside are prone to rust, causing the bolts and flanges to lock, making it inconvenient to disassemble and repair subsequent pipelines and membrane separators.

[0030] See also Figure 1 - Figure 5 A sleeve-type pervaporation membrane separator comprises a cylinder 1, a head 2 and a locking component 3, wherein both ends of the cylinder 1 are connected to a fixing plate 11.

[0031] The head 2 includes an elliptical part 21 and a sealing plate 22 fixed on the elliptical part 21. The sealing plate 22 is in contact with the fixed plate 11. The sealing plate 22 and the fixed plate 11 are both circular and have the same diameter. A vacuum interface is connected to one of the heads 2. A feed port and a discharge port are provided at the same height on the cylinder 1, and a steam inlet is provided on the lower side of the cylinder 1. A steam condensate outlet is provided near the upper side. The feed port, discharge port, steam inlet and steam condensate outlet are all existing technologies and will not be described in detail.

[0032] The locking component 3 is arranged on the cylinder 1. The locking component 3 includes a plurality of fixing seats 31 fixed on the cylinder 1. There are four fixing seats 31. The fixing seats 31 extend obliquely downward. A threaded rod 32 is threadedly connected to the fixing seat 31. The axis of the threaded rod 32 is aligned with the center of the cylinder 1. One end of the threaded rod 32 is connected to the locking plate 33 that squeezes the sealing plate 22 and the fixing plate 11. The other end of the threaded rod 32 is fixed with a turning handle 34, which is convenient for rotation.

[0033] The side of the sealing plate 22 facing the elliptical part 21 is a conical surface 23, and the locking plate 33 is provided with an extrusion conical surface 35 adapted to the conical surface 23. Through the cooperation of the conical surface 23 and the extrusion conical surface 35, the sealing plate 22 can be tightly attached to the fixing plate 11, thereby achieving a sealing effect.

[0034] The fixing seat 31 is provided with a limiting groove 311, and the locking plate 33 is fixed with a limiting portion 331 adapted to the limiting groove 311. The threaded rod 32 is rotatably connected to the limiting portion 331. The upper and lower surfaces of the limiting portion 331 are in contact with the top and bottom walls of the limiting groove 311 respectively, so that the limiting portion 331 moves linearly with the locking plate 33. In order to prevent the threaded rod 32 from being exposed to rust for a long time, shielding plates 36 that block the limiting groove 311 are fixed on both sides of the limiting portion 331. The two shielding plates 36 block both sides of the limiting groove 311 to prevent the threaded rod 32 from being rusted by external rain.

[0035] To further prevent rust, the fixing seat 31 is fixed with a protrusion 37, and the threaded rod 32 is fixed with a shielding cover 38 that is sleeved on the protrusion 37. When the locking plate 33 abuts the sealing plate 22, the shielding cover 38 is sleeved on the protrusion 37 to partially shield and protect the threaded rod 32 outside the fixing seat 31. The shielding plate 36 cooperates with the shielding cover 38 to shield all threaded parts, thereby preventing rust and facilitating the rotation of the threaded rod 32 when disassembling the head 2.

[0036] The fixing plate 11 is provided with a through slot 111, which is offset from the fixing seat 31. A hanging plate 24 is fixed to the sealing plate 22, passing through the through slot 111. The hanging plate 24 is bent into an inverted L-shape, so that the bent portion is hung on the fixing plate 11 to prevent it from falling. During installation, it can be hung on the fixing plate 11 first, and then the threaded rods 32 are rotated one by one, thereby making the locking plate 33 press against the sealing plate 22 and the fixing plate 11. A grip 25 is fixed to the elliptical portion 21, which facilitates the removal and installation of the head 2.

[0037] When the cover 38 is moved, the cover 38 is separated from the protrusion 37, and the threaded rod 32 drives the locking plate 33 to move. The locking plate 33 leaves the lower side of the sealing plate 22, and the sealing plate 22 moves with the shielding plate 36. When all the locking plates 33 are separated from the sealing plate 22, the hanging plate 24 is hung on the fixed plate 11. There is no need to hold it up manually. Hold the handle 25 to rotate the cover 2. When the hanging plate 24 is When it contacts the inner wall of the through groove 111, it moves away from the cylinder 1 in the axial direction of the cylinder 1, thereby separating the head 2 and the fixed plate 11. When installing the head 2, hold the gripping rod 25 so that the hanging plate 24 is aligned with the through groove 111. After the hanging plate 24 passes through the through groove 111, rotate the head 2 so that the head 2 is hung on the fixed plate 11. At this time, there is no need to manually hold up the head 2. Then, rotate the threaded rod 32 one by one, so that the locking plate 33 is pressed against the sealing plate 22 and the fixed plate 11.

[0038] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are provided for illustrative purposes only and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any changes or modifications to the embodiments of the present invention are possible without departing from the principles described.
