[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6, the present invention provides the following technical solutions: a preparation device and process for an inorganic ceramic membrane for S-shaped cross-section water purification treatment, including a preparation tank 1. A mounting tank 12 is fixedly installed at the bottom of the preparation tank 1. A servo motor 23 is fixedly installed in the middle of the bottom of the mounting tank 12. A driving gear 24 is fixedly installed on the rotating shaft of the output end of the servo motor 23. Movable rods 25 are rotatably installed on both the left and right sides inside the preparation tank 1 and the mounting tank 12. A driven gear 26 is fixedly installed on the lower side of the surface of the movable rod 25, and the driving gear 24 is meshed with the driven gear 26. A stirring blade 29 is fixedly installed on the upper side of the surface of the movable rod 25, and the stirring blade 29 is arranged inside the preparation tank 1, and the driving gear 24 and the driven gear 26 are arranged inside the mounting tank 12. An electric heater 8 is fixedly installed on the left side of the preparation tank 1. A heating pipe 30 is fixedly installed inside the preparation tank 1, and the heating pipe 30 is arranged above the stirring blade 29. A temperature sensor 31 is fixedly installed on the right side of the preparation tank 1. A movable top plate 4 is movably installed on the top of the preparation tank 1. Mounting cylinders 6 are fixedly installed on both the left and right sides of the top of the movable top plate 4. A driving motor 28 is fixedly installed on the top of the mounting cylinder 6. A rotating fan blade 27 is fixedly installed on the rotating shaft of the output end of the driving motor 28. An air inlet hole 17 is opened on the top of the mounting cylinder 6. A drain pipe 11 is fixedly installed on the lower side of the back of the preparation tank 1. A switch valve 13 is fixedly installed on the top of the drain pipe 11.

[0031] When the device is in use, first, the solvent, ceramic powder, and nanoparticles can be poured into the interior of the preparation tank 1. Starting the servo motor 23 can drive the driving gear 24 to rotate through the rotating shaft at the output end. Since the driving gear 24 and the driven gear 26 are meshed and connected, the rotation of the driving gear 24 can drive two groups of driven gears 26, the movable rod 25, and the stirring blades 29 to rotate simultaneously. As a result, the ceramic powder and nanoparticles can be more evenly dispersed in the solvent, and a suspension with a better adhesion effect can be formed, which is beneficial to improving the use effect of the prepared inorganic ceramic membrane. Moreover, the deposition method can control the thickness and pore size distribution of the membrane to ensure that the inorganic ceramic membrane is suitable for different usage environments. After the deposition is completed, the switch valve 13 can be turned on, so that the excess solvent inside the preparation tank 1 can flow out through the drain pipe 11. Then, starting the driving motor 28 can drive the rotating fan blade 27 to rotate through the rotating shaft at the output end. By using the electric heater 8, the heating pipe 30 can be heated, increasing the temperature inside the preparation tank 1. This can dry and heat-treat the porous support body with the adhered ceramic powder and nanoparticles, which is beneficial to enhancing the structural stability. The drying process can effectively remove the solvent or dispersion medium, preventing the film layer from cracking or the structure from collapsing due to the volatilization of the residual liquid during subsequent high-temperature treatment. Through high temperature, chemical bonding or solid-phase diffusion can be promoted between the ceramic particles, thereby improving the bonding strength between the film layer and the support body and reducing the risk of delamination. Regarding the settings of the controller 14 and the control panel 19, and since the controller 14 is electrically connected to the control panel 19 and the controller 14 is electrically connected to the servo motor 23, the rotation speed of the servo motor 23 can be conveniently controlled through the controller 14 and the control panel 19, so as to change the rotation speed of the stirring blades 29, thereby facilitating the control of the stirring rate and enabling the device to produce different stirring and mixing effects. Regarding the settings of the support rod 2 and the support plate 9, it can facilitate the device to be placed horizontally on the ground. Since multiple rubber gaskets 20 are linearly arranged at the bottom of the support plate 9, the friction between the bottom of the support plate 9 and the ground can be increased, making it difficult for the support plate 9 to slide on the ground, which is beneficial to ensuring the stability of the device during operation. Regarding the setting of the observation window 3, it can facilitate the installation of the glass plate 10. Moreover, since the glass plate 10 is transparent, it is convenient for the user to observe the situation inside the preparation tank 1, increasing the convenience of using the device. Regarding the setting of the baffle 21, and since the baffle 21 is arranged above the observation window 3, it can prevent the liquid from splashing on the outside of the glass plate 10 and avoid affecting the user's observation field of view. Regarding the setting of the fixed handle 7, it can facilitate the user to carry the device conveniently by holding the fixed handle 7. The anti-slip sleeve 18 can increase the friction on the surface of the fixed handle 7, making it difficult to slip when holding the fixed handle 7. Regarding the setting of the installation handle 5, it can facilitate the removal of the movable top plate 4, and the protective sleeve 16 can make the installation handle 5 more comfortable to hold.By inserting the connecting buckle 15 into the interior of the connecting card slot 22, it is convenient to fix the movable top plate 4 on the top of the preparation box 1. In this device, the cross-section of the porous support used is S-shaped, so the cross-section of the prepared inorganic ceramic membrane is also S-shaped. Since the S-shaped inorganic ceramic membrane has a larger contact area with water, compared with ordinary inorganic ceramic membranes, the S-shaped inorganic ceramic membrane has the advantages of higher throughput, stronger anti-fouling performance and lower cost, which is beneficial to improving the quality of the supplied water. All the electrical equipment in this device is powered by an external power supply.

[0032] In one aspect of this embodiment, the arrangement of the support rod 2 and the support plate 9 facilitates the device to be placed horizontally on the ground. Since a plurality of rubber gaskets 20 are linearly arranged at the bottom of the support plate 9, the friction between the bottom of the support plate 9 and the ground can be increased, making it difficult for the support plate 9 to slide on the ground, which is beneficial to ensuring the stability of the device during operation.

[0033] In one aspect of this embodiment, regarding the arrangement of the controller 14 and the control panel 19, since the controller 14 is electrically connected to the control panel 19 and the controller 14 is electrically connected to the servo motor 23, the rotation speed of the servo motor 23 can be conveniently controlled through the controller 14 and the control panel 19, so as to change the rotation speed of the stirring blade 29, thereby facilitating the control of the stirring rate and enabling the device to produce different stirring and mixing effects.

[0034] In one aspect of this embodiment, the arrangement of the observation window 3 facilitates the installation of the glass plate 10. Moreover, since the glass plate 10 is transparent, it is convenient for the user to observe the situation inside the preparation box 1, increasing the convenience of using the device. Regarding the arrangement of the baffle 21, since the baffle 21 is arranged above the observation window 3, it can prevent liquid from splashing on the outside of the glass plate 10 and avoid affecting the user's observation field of view.

[0035] In one aspect of this embodiment, the arrangement of the fixed handle 7 facilitates the user to carry this device by holding the fixed handle 7. The anti-slip sleeve 18 can increase the friction on the surface of the fixed handle 7, making it not easy to slip when holding the fixed handle 7. Regarding the arrangement of the installation handle 5, it is convenient to remove the movable top plate 4, and the protective sleeve 16 can make the installation handle 5 more comfortable to hold. By inserting the connecting buckle 15 into the interior of the connecting card slot 22, it is convenient to fix the movable top plate 4 on the top of the preparation box 1.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
