Description

Technical Field

[0001] This utility model relates to the field of inorganic membrane molecular sieve technology, specifically to an inorganic membrane molecular sieve experimental device. Background Technology

[0002] Inorganic membrane molecular sieve experiments primarily focus on the research and preparation of inorganic membrane materials with specific molecular sieving functions. The experimental process includes material selection, synthesis, characterization, and performance testing. For example, by controlling reaction conditions and raw material ratios, molecular sieve membranes with specific pore sizes and channel structures are synthesized. Then, various techniques are used to characterize them, such as X-ray diffraction and scanning electron microscopy, to determine their structure and properties.

[0003] A molecular sieve membrane filtration device, authorized by announcement number CN204247076U, includes connecting pipes, control valves, and a ceramic membrane separator. The ceramic membrane separator has a feed inlet, a concentrate outlet, a filtrate outlet, and a backwash liquid inlet. The device also includes a ceramic membrane separator backwashing unit and a ceramic membrane separator preheating unit. The backwashing unit includes a backwash tank and a backwash pump. The backwash pump inlet is connected to the backwash tank outlet, and the backwash pump outlet is connected to the ceramic membrane separator backwash liquid inlet. A pressure-reducing and diversion pipeline is provided between the backwash pump outlet and the backwash tank. The ceramic membrane separator preheating unit includes a preheating circulation tank. The preheating circulation tank outlet is connected to the feed supply pipe, and the preheating circulation tank inlet is connected to the concentrate output pipe. This molecular sieve membrane filtration device features a simple structure, low manufacturing cost, easy control of the backwashing process, and good backwashing effect.

[0004] As shown in the above equipment, although the existing experimental device has a simple backflushing device structure, low manufacturing cost, easy control of the backflushing process, and good backflushing effect, if it lacks a filtration structure, impurities in the feed may directly enter the pervaporation membrane separation system, causing membrane surface contamination, damaging the membrane, reducing the membrane's permeate flux and separation efficiency, and shortening the membrane's service life.

A limit block 636 is connected to the inner wall of the connecting slide plate 635.

[0034] The fixing component 632 includes a mounting ring 6323, which is disposed inside the sealing connection seat 633. The inner wall of the sealing connection seat 633 has a groove 6324. A fixing post 6322 is slidably connected to the outer wall of the mounting ring 6323. The fixing post 6322 passes through the mounting ring 6323.

[0037] The second embodiment differs from the first embodiment in that the auxiliary connecting assembly 64 includes an auxiliary sealing plate 641, one end of which is rotatably connected to a rotating shaft.

[0039] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0040] When inorganic membrane molecular sieve experiments are required, the solvent is first transported to the preheater 3 via the inlet pipe 4 using a liquid pump. It then exchanges heat with the dehydrated raw material in the preheater 3 to recover heat. Afterwards, it enters the evaporator 5 through a pipe to vaporize and superheat to a certain temperature. The vaporized solvent then passes through a pipe and is filtered by the filter plate 6384 in the sealing connection assembly 63 and auxiliary connection assembly 64 to remove impurities. It then enters the membrane tank body 61 through the feed pipe 62 for separation and filtration. The processed solvent is divided into permeate vapor and gaseous product. The separated gaseous product is discharged through the outlet pipe, while the permeate vapor is transported to the preheater 3 through the liquid outlet 65, the drain pipe 66, and the connecting pipe to exchange heat with the raw material for heat recovery. After passing through cooling water, a gaseous permeate is collected and transported through a pipe to the permeate condenser 7 for cooling with chilled water. Finally, it is sent through a pipe to the gas-liquid separator 8 for further separation. After the gas reaches the standard, it is discharged. The permeate is discharged through the outlet pipe via a liquid pump. When maintenance or replacement of the screen membrane tank body 61 is required, the pull plate 6326 can be pulled. The movement of the pull plate 6326 can move the mounting bracket 6321 connected to one end. The movement of the mounting bracket 6321 can move the fixed column 6322 connected to one end. The movement of the fixed column 6322 can compress the return spring 6325 sleeved on its outer wall. When the fixed column 6322 leaves the range inside the connecting slide plate 635, the auxiliary sealing plate 641 can be rotated. When the auxiliary sealing plate 641 is rotated, the insertion groove 643 on the outer wall of the connecting ring 642 is aligned with the connecting slide plate 635 on the outer wall of the sealing connection seat 633. The sealing connection assembly 63 and the auxiliary connection assembly 64 can be separated, and the screen membrane tank body 61 can be separated from the pipeline. Then, the screen membrane assembly 6 can be completely removed for maintenance or replacement by removing the bolts on the mounting seat 67.
