Description

Technical Field

[0001] This utility model relates to the field of filtration component technology, specifically a tubular ceramic membrane component. Background Technology

[0002] Tubular ceramic membrane modules are highly efficient filtration devices consisting of multiple tubes containing microporous ceramic membranes, typically encapsulated in a robust housing. The ceramic material imparts exceptional chemical and thermal stability to the membrane module, enabling it to withstand extreme pH levels, high temperatures, and highly corrosive environments. Its microporous structure allows small molecules to pass through while retaining large molecules or particulate matter, thus achieving precise filtration and purification.

[0003] In existing technologies, tubular ceramic membrane modules typically seal the gap between the ceramic membrane end and the mold shell by fitting a sealing ring on the outer wall of the ceramic membrane end. Because of the presence of the sealing ring, the friction between the ceramic membrane end and the mold shell is relatively large, resulting in greater resistance during insertion and removal, and making assembly more difficult.

The fixing mechanism includes a fixing sleeve and a fixing cover, and an exhaust valve is fixedly connected to one side of the fixing sleeve, an air inlet valve is fixedly installed on one side of the fixing sleeve, and an air inlet groove is opened inside the fixing sleeve. An installation ring is fixedly installed inside the fixing sleeve, and several vent holes are opened inside the installation ring. A first sealing ring is fixedly installed on the inner wall of the vent holes, and the first sealing ring is located inside the fixing sleeve.

[0013] 1. The ceramic membrane mechanism is fixed inside the outer shell assembly and the fixing mechanism by the cooperation of the fixed sleeve, fixed cover and retaining ring. The first sealing ring is fixed inside the fixed sleeve by the mounting ring. The air pressure inside the inflation tank is increased by connecting the air inlet valve to the air pump, thereby causing the first sealing ring to inflate and expand, squeezing the outer wall of the ceramic membrane mechanism, ensuring the sealing between the ceramic membrane mechanism and the fixing mechanism.

The first sealing ring 207 is fixed inside the fixing sleeve 201 by the mounting ring 205. The air pressure inside the inflation groove 204 is increased by connecting the air inlet valve 203 to the air pump, thereby causing the first sealing ring 207 to inflate and expand, squeezing the outer wall of the ceramic membrane mechanism 3, ensuring the sealing between the ceramic membrane mechanism 3 and the fixing mechanism 2. When it is necessary to remove or insert the ceramic membrane mechanism 3, it is only necessary to reduce the air pressure inside the inflation groove 204 by the exhaust valve 202, which can reduce the friction between the first sealing ring 207 and the ceramic membrane mechanism 3.

When it is necessary to remove or insert the ceramic membrane mechanism 3, it is only necessary to reduce the air pressure inside the inflation groove 204 through the exhaust valve 202 to reduce the friction between the first sealing ring 207 and the ceramic membrane mechanism 3. In summary, this equipment has the advantage of convenient replacement of the ceramic membrane mechanism 3.
