Description

Technical Field

[0001] The utility model relates to the technical field of ceramic membranes, and particularly relates to a self-cleaning ceramic membrane module. Background Art

[0002] The tubular ceramic membrane is an asymmetric membrane prepared from inorganic ceramic materials through a special process. Under the action of pressure, the raw material liquid flows inside or outside the membrane tube. Small molecule substances or liquids pass through the membrane, while macromolecule substances or solids are intercepted by the membrane, so as to achieve the purposes of separation, concentration, purification, environmental protection, etc. Chinese Patent with the publication number CN207243589U discloses a high-temperature resistant ceramic membrane for sewage treatment. This high-temperature resistant ceramic membrane for sewage treatment is provided with a high-temperature resistant PE tube. When the device is used under harsh conditions such as high temperature, the high-temperature resistant PE tube can ensure that the components inside the device will not deform due to high temperature, thus playing a role in protecting the device. For this reason, we propose a solution for a high-temperature resistant ceramic membrane for sewage treatment. Chinese Patent discloses a high-temperature resistant ceramic membrane for sewage treatment (the authorized announcement number is CN220460342U). This patented technology discloses a high-temperature resistant ceramic membrane for sewage treatment, including a ceramic membrane body. The left end of the ceramic membrane body is fixedly connected with a connecting cylinder. A filter cylinder is placed inside the connecting cylinder. A filter plate is fixedly connected to the inner wall of the filter cylinder. A threaded cover is sleeved on the outer surface of the filter cylinder. The threaded cover is threadedly connected with the connecting cylinder. This high-temperature resistant ceramic membrane for sewage treatment is provided with a high-temperature resistant tube inside the ceramic membrane body, which can enable the ceramic membrane to withstand high temperature without deformation. And at the left end inlet of the ceramic membrane body, a filter cylinder with a filtering device is provided, which can filter the sewage before it enters the ceramic membrane for filtration, and filter out some larger impurities in the sewage to prevent the larger impurities from blocking the ceramic membrane. Moreover, the connection between the filter cylinder and the ceramic membrane body is convenient, enabling the staff to replace the ceramic membrane more quickly. This patented technology solves the problem that during the filtration process, due to a large amount of garbage in the sewage, the ceramic membrane is easily blocked, so the ceramic membrane needs to be replaced frequently.

[0003] However, when the existing ceramic membrane is cleaned, it is usually removed from the pipeline device and then cleaned by high-pressure flushing. The problem that the ceramic membrane can be cleaned without being disassembled in the prior art needs to be solved.

[0004] Therefore, those skilled in the art provide a self-cleaning ceramic membrane module to solve the problems raised in the above background art. Summary of the Utility Model
