[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Please see Figures 1 to 3 A ceramic membrane with good sealing performance includes a separation layer 1, a transition layer 2 fixedly installed at the bottom of the separation layer 1, and a support layer 3 fixedly installed at the bottom of the transition layer 2.

[0029] The separation layer 1 includes a first membrane layer 11, and a separation membrane 12 is fixedly mounted on the bottom of the first membrane layer 11. The separation membrane 12 has a plurality of first openings 13 inside.

[0030] The transition layer 2 includes a transition membrane 21 fixedly installed at the bottom of the separation membrane 12;

[0031] The support layer 3 includes a first support component 31 fixedly installed at the bottom of the transition membrane 21, a second support component 32 fixedly installed inside the first support component 31, and a second membrane layer 34 fixedly installed at the bottom of the second support component 32.

[0032] In this embodiment, as Figure 1 As shown, the separation membrane 12 forms a separation structure through the first opening 13 on its outer surface.

[0033] In this embodiment, as Figure 2 As shown, a number of gradient holes 22 are formed on the outer surface of the transition membrane 21.

[0034] In this embodiment, as Figure 3 As shown, the top of the second support component 32 has several second openings 33.

[0035] In this embodiment, as Figure 3 As shown, the first support component 31 and the second support component 32 constitute a support structure.

[0036] The working process of this well-sealed ceramic membrane is as follows:

[0037] First, the user needs to pre-treat the first membrane layer 11 by evenly applying the sol to its bottom. The sol will serve as a connecting medium to ensure the uniformity and firmness of the subsequent bonding. After the application is completed, immediately attach the separation membrane 12 flatly to the bottom of the first membrane layer 11. After ensuring that the two membranes are tightly bonded, just wait for the sol to solidify.

[0038] After the bonding and solidification are completed, a second sol coating needs to be applied to the bottom of the separation membrane 12 to ensure that the coating thickness is consistent with the first coating. After the sol is evenly distributed, the transition membrane 21 is quickly attached to the bottom of the separation membrane 12. The gradient pores 22 inside the transition membrane 21 have a gradient structure. This unique design not only plays a progressive interception role in the gas or liquid filtration process, but also forms a mechanical interlocking effect between the layers. When the sol is solidified, the gradient pore structure 22 and the sol permeate each other, effectively enhancing the bonding strength between the separation membrane 12 and the transition membrane 21, providing a reliable base for the stable operation of the subsequent separation layer 1.

[0039] After the sol solidifies, the user needs to apply the sol to the bottom of the transition membrane 21. Then the user can stick the first support component 31 to the bottom of the transition membrane 21, and then stick several second support components 32 into the gaps of the first support component 31. The first support component 31 and the second support component 32 stuck to the bottom of the transition membrane 21 can provide support for the ceramic membrane.
