[0036] Example

[0037] See also Figure 1-Figure 3 This embodiment discloses a large-aperture ceramic membrane tube installation structure, including:

[0038] A positioning plate 101, wherein the positioning plate 101 is used to be installed on the outer sleeve, and a mounting groove 102 is provided on the positioning plate 101;

[0039] A limiting portion 103, wherein the limiting portion 103 is connected to the mounting groove 102, and a limiting groove 104 is provided on the limiting portion 103, and a ready-made mounting area between the limiting groove 104 and the mounting groove 102 is used to limit the ceramic membrane tube;

[0040] The sealing component 105 is disposed between the limiting portion 103 and the mounting groove 102 , and is used to seal the gap between the ceramic membrane tube and the positioning plate 101 .

[0041] In this embodiment, the positioning plate 101 is threadedly connected to the upper and lower ends of the outer sleeve, and a limiting portion 103 and a sealing assembly 105 are installed in each positioning plate 101 to limit and seal the ceramic sleeve; by threading the positioning plate 101 on the outer sleeve, the positioning plate 101 can be removed from the outer sleeve when the outer sleeve needs to be cleaned, and by making the positioning plate 101 and the outer sleeve detachably connected, it can also be avoided that when the positioning plate 101 sealed welded to the outer sleeve in the prior art is damaged or a gap appears at the connection between the positioning plate 101 and the outer sleeve to cause liquid leakage, it is difficult for personnel to separate the positioning plate 101 from the cylinder body, and the entire tubular ceramic membrane assembly can only be abandoned, causing unnecessary waste. The limiting part 103 threadedly connected in the installation groove 102 can limit the ceramic diaphragm tube arranged between the limiting part 103 and the sealing component 105; the ceramic diaphragm tube is pressed between the limiting groove 104 and the sealing component 105 during the downward movement of the limiting part 103, and the sealing component 105 further seals the gap between the ceramic diaphragm tube and the positioning plate 101 under the pressure of the limiting part 103, so as to avoid the formation of leakage points between the positioning plate 101 and the ceramic diaphragm tube, which affects the stability of the ceramic diaphragm tube under pressure shock.

[0042] Specifically, the ceramic membrane tube is provided with a stepped platform 106 for cooperating with the limiting groove 104. The limiting portion 103 threadedly connected in the installation groove 102 can limit the ceramic membrane tube installed between the limiting groove 104 and the sealing assembly 105.

[0043] Specifically, the sealing assembly 105 includes a support ring 107 and a sealing ring body 108. The support ring 107 is used to contact the limiting portion 103, and the sealing ring body 108 is used to contact the installation groove 102. The step platform 106 is arranged in the existing limiting area between the limiting groove 104 and the support ring 107. The limiting portion 103 threadedly connected in the installation groove 102 can limit the step platform 106 arranged between the limiting groove 104 and the support ring. When the limiting portion 103 moves downward to press the step platform 106 against the support ring, the support ring squeezes the sealing ring body 108 under the action of the limiting portion 103, so that the sealing ring body 108 is deformed, which will further seal the gap between the ceramic membrane tube and the positioning plate 101.

[0044] Specifically, the support ring 107 has a rectangular cross section. The support ring 107 is made of rubber material, and the support ring 107 with a rectangular cross section can further improve the supporting effect on the ceramic membrane tube and can apply uniform pressure to the sealing ring body 108 .

[0045] Specifically, the sealing ring body 108 is an O-shaped sealing ring. The sealing ring body 108 is made of rubber material, and the sealing effect of the sealing ring body 108 on the gap between the ceramic membrane tube and the positioning plate 101 after being squeezed by the support ring 107 can be further improved.

[0046] Specifically, a circular arc transition section is provided on the side of the installation groove 102 that contacts the sealing ring body 108. By providing the circular arc transition section, the installation groove 102 and the sealing ring body 108 can be more closely fitted, further improving the sealing effect of sealing the gap between the ceramic membrane tube and the positioning plate 101.

[0047] Specifically, the limiting portion 103 is provided with a first groove 109. The first groove 109 provided on the limiting portion 103 can facilitate the installation of the limiting portion 103 into the installation slot 102.

[0048] Specifically, the positioning plate 101 is provided with a second groove 110. The second groove 110 provided on the positioning plate 101 is used to position the positioning plate 101 and the outer sleeve connected to the positioning plate 101.

[0049] Specifically, a limiting platform is provided in the outer sleeve for limiting the positioning plate 101. The contact area between the positioning plate 101 and the outer sleeve can be increased by providing the limiting platform, so that the positioning plate 101 can be installed more stably.

[0050] Specifically, a clearance groove is provided at the connection between the positioning disc 101 and the outer sleeve. The clearance groove is provided on the positioning disc 101, and the clearance groove limits the positioning disc 101 after contacting the outer sleeve, thereby preventing the positioning disc 101 from being over-rotated and causing compression to the outer sleeve during the process of threaded connection with the outer sleeve.
