Description

Technical Field

[0001] The utility model relates to the technical field of tubular ceramic membranes, and specifically relates to an installation and fixation structure for a tubular ceramic membrane. Background Technique

[0002] A tubular ceramic membrane is a micron or sub-micron level thin film made of materials such as high-purity silicate or alumina, with extremely high porosity and selective separation performance, and is widely used in fields such as water treatment, gas separation, and organic solvent recovery. The basic structure of a tubular ceramic membrane includes a porous support body and a thin film layer covering the surface of the support body. Its pore size is generally between 1 and 10 nanometers, and the porosity can reach more than 50%, so it has good filtering and separation effects.

[0003] However, in the current prior art, after the ceramic membrane is installed inside the pipe wall, a sealing ring is used for sealing treatment. However, during the use of the tubular ceramic membrane, when the liquid is transported through the pipeline, it will generate a certain impact on the sealing ring inside the pipe wall. After a long time of impact, the sealing ring will deform or crack, thus affecting its sealing effect and the normal operation of the equipment. Content of the Utility Model

[0004] The purpose of the utility model is to provide an installation and fixation structure for a tubular ceramic membrane to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A sealing component for sealing during installation is arranged outside the ceramic membrane. The sealing component includes a plurality of installation bins arranged inside the delivery pipe. Sealing rings are installed on the inner walls of the plurality of installation bins. A hole groove is arranged on the outer wall of the ceramic membrane. A docking pad is arranged inside the hole groove. A positioning groove is arranged on the inner wall of the hole groove. An air chamber is arranged on one side of the positioning groove. A cavity is arranged at the end cross-section of the ceramic membrane. A connecting rod is arranged inside the positioning groove. A piston is arranged on the outer wall of the connecting rod. A pull ring is arranged at one end of the connecting rod away from the positioning groove.

[0007] As a preferred scheme of the utility model, the sealing ring is inlaid and connected with the inner wall of the installation bin. The sealing ring is a stepped inlaid structure. The docking pad is a stepped conical structure matching the sealing ring.

[0008] As a preferred scheme of the utility model, the ceramic membrane is slidably connected with the inner wall of the installation bin. After the ceramic membrane is installed, the hole groove on the outer wall corresponds to the position of the sealing ring inside the installation bin.

[0009] As a preferred solution of the present utility model, the docking pad is located in the hole groove, one end is connected to the inner wall of the hole groove, and the other end extends into the positioning groove. The conical end of the docking pad protrudes from the hole groove and meshes with the sealing ring.

[0010] As a preferred solution of the present utility model, one end of the connecting rod is located in the positioning groove and is slidably connected to the inner wall of the positioning groove through a slide rail. The other end penetrates the positioning groove and the air chamber and extends into the cavity, and is connected to the pull ring.

[0011] As a preferred solution of the present utility model, the air chamber is filled with high-pressure gas. The outer wall of the connecting rod in the air chamber area is connected to the piston, and the piston can slide on the inner wall of the air chamber through the connecting rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In response to the problems raised in the background art, the present application adopts a sealing component. By inlaying a sealing ring on the pipe wall and installing a corresponding matching docking pad on the outer wall of the tubular ceramic membrane, it is docked with the sealing ring during installation. At the same time, through the conical structures of the docking pad and the sealing ring, the thickness of the sealing ring can be increased and its tight fit with the closure can be increased. When the sealing ring is impacted during liquid transportation, only the outermost layer after matching with the sealing ring can be impacted. The quality of liquid transportation resistance to impact is improved through the stepped levels, thereby improving the sealing effect and service life of the sealing ring.

[0013] The present utility model realizes improving the tight fit with the pipe wall, increasing the thickness of the sealing ring, enhancing the anti-impact effect of the sealing ring, and increasing the service life by adopting a sealing ring with a stepped conical structure.

The docking pad 401 and the sealing ring 201 are made of the same material and mesh with the sealing ring 201 inside the pipe wall when the ceramic membrane 3 is installed to achieve sealing. Moreover, both the docking pad 401 and the sealing ring 201 are stepped conical structures, which increase the tightness of fitting and the sealing effect after meshing, and increase the thickness of the sealing structure, improving the anti-impact effect during the impact of liquid transportation and reducing the damage probability (the inner wall of the docking pad 401 is a groove structure, and when stretched on both sides, the docking pad 401 can shrink into the hole groove 4, so as to facilitate the installation of the ceramic membrane 3 to the designated position). A positioning groove 5 is provided on the inner wall of the hole groove 4. A gas chamber 501 is provided on one side of the positioning groove 5. The high-pressure gas in the gas chamber 501 can act on the piston 601, thereby driving the connecting rod 6 to move in the positioning groove 5 and the gas chamber 501 to push the docking pad 401 to bulge in the hole groove 4. A cavity 502 is provided at the end cross-section of the ceramic membrane 3. A connecting rod 6 is provided inside the positioning groove 5. The connecting rod 6 links the docking pad 401 with the pull ring 602. A piston 601 is provided on the outer wall of the connecting rod 6. A pull ring 602 is provided at one end of the connecting rod 6 away from the positioning groove 5. The pull ring 602 is convenient for driving the connecting rod 6 to contract the docking pad 401.

[0021] In this embodiment, all electrical components are controlled by a conventional controller.

[0022] For the embodiment, please refer to Figures 1-3, the sealing ring 201 is inlaid and connected with the inner wall of the installation bin 2. The sealing ring 201 is of a stepped embedded structure. The docking pad 401 is of a stepped conical structure matching the sealing ring 201. The ceramic membrane 3 is slidably connected with the inner wall of the installation bin 2. After the ceramic membrane 3 is installed, the hole groove 4 on the outer wall corresponds to the position of the sealing ring 201 in the installation bin 2. The docking pad 401 is located in the hole groove 4, one end is connected with the inner wall of the hole groove 4, and the other end extends into the positioning groove 5. The conical end of the docking pad 401 protrudes from the hole groove 4 and meshes with the sealing ring 201.

At the same time, pull the pull ring 602 to drive the docking pad 401 to extend into the positioning groove 5 in cooperation with the connecting rod 6, so that the docking pad 401 contracts into the hole groove 4. After the ceramic membrane 3 is installed in the designated position, release the pull ring 602. Then, the high-pressure gas in the air chamber 501 acts on the piston 601 to drive the connecting rod 6 to slide and contract, and cooperate with the toughness of the docking pad 401 itself to make it bulge and mesh with the sealing ring 201 in the installation bin 2, so as to achieve the sealing effect.

[0023] The working process of the present utility model: When in use, first embed the ceramic membrane 3 into the designated position in the corresponding installation bin 2 of the conveying pipe 1. At the same time, pull the pull ring 602 to drive the docking pad 401 to extend into the positioning groove 5 in cooperation with the connecting rod 6, so that the docking pad 401 contracts into the hole groove 4.
