[0020] As Figure 1 , 2 shown, a ceramic membrane device for wastewater treatment includes a filtering cylinder 1. An inlet 2 is arranged on the rear surface of the filtering cylinder 1. A cylinder cover 9 is installed on the front surface of the filtering cylinder 1. A water outlet 17 is formed on the surface of the cylinder cover 9. A fixing rod 15 is fixedly installed on the inner surface of the cylinder cover 9. A plurality of plate-shaped ceramic membranes 16 are equidistantly installed in the middle of the fixing rod 15.

A first hydraulic cylinder 10 is fixedly installed on the front surface of the installation ring 7. The output end of the first hydraulic cylinder 10 is arranged on the surface of the cylinder cover 9.

[0021] As Figure 1 shown, a plurality of liquid outlets 3 are equidistantly arranged on the lower surface of the filtering cylinder 1, which is convenient for the scraped materials to fall off.

[0022] As Figure 1 shown, a mounting rod 4 is fixedly installed on the side surface of the mounting ring 7. A fixing plate 5 is fixedly installed at the lower end of the mounting rod 4. A plurality of fixing holes 6 are equidistantly formed on the upper surface of the fixing plate 5, which can facilitate the installation of this device.

[0023] As Figure 1 , 3As shown, a chute 11 is provided on the surface of the cylinder cover 9. A slider 13 is slidably installed inside the chute 11. The output end of the first hydraulic cylinder 10 is equipped with a screw sleeve 12. A threaded hole 14 is provided on the surface of the slider 13. The screw sleeve 12 is meshed and arranged inside the threaded hole 14. When it is necessary to replace the plate-shaped ceramic membrane 16, first rotate the screw sleeve 12 to disengage the screw sleeve 12 from the inside of the threaded hole 14. At this time, the cylinder cover 9 can be disengaged from the first hydraulic cylinder 10. Then, the output end of the second hydraulic cylinder 803 is telescoped to lift the connecting plate 806 upward, so that several scraping plates 807 are disengaged from the surface of the plate-shaped ceramic membrane 16. At this time, the staff pulls the cylinder cover 9 to disengage the plate-shaped ceramic membrane 16 from the filter cylinder 1. Conversely, installation can be carried out to replace the plate-shaped ceramic membrane 16.

[0024] As Figure 2 , 3 , 4 shows that the rotating cleaning assembly 8 includes a limiting rod 801, a servo motor 804, and a gear 808. The limiting rod 801 is fixedly installed on the side surface of the filter cylinder 1. The servo motor 804 is fixedly installed on the side surface of the filter cylinder 1. The gear 808 is installed on the surface of the cylinder cover 9. The top end of the limiting rod 801 is fixedly installed with a top plate 802. The lower surface of the top plate 802 is fixedly installed with a second hydraulic cylinder 803. The output end of the second hydraulic cylinder 803 is fixedly installed with a connecting plate 806. The lower surface of the connecting plate 806 is fixedly installed with several scraping plates 807 at equal intervals. The scraping plates 807 slidably penetrate through the filter cylinder 1 and are attached to the surface of the plate-shaped ceramic membrane 16. The output end of the servo motor 804 is fixedly installed with a gear 805. The gear 805 is meshed and connected with several gears 808.

[0025] The working principle of this ceramic membrane device for wastewater treatment:

[0026] During use, when this device is performing the filtration work, first, sewage enters the inside of the filter cylinder 1 from the water inlet 2, and the sewage passes through the surface of the plate-shaped ceramic membrane 16 to filter the sewage. Moreover, due to the different filtration specifications of the set plate-shaped ceramic membrane 16, the sewage can be filtered more thoroughly. The filtered water source will flow out from the water outlet 17. And when it is necessary to filter the impurities on the surface of the plate-shaped ceramic membrane 16, the servo motor 804 is driven to rotate the gear 805, so that the gear 805 drives a number of gear teeth 808 to rotate, and then a number of cylinder covers 9 can be rotated. At this time, a number of plate-shaped ceramic membranes 16 are simultaneously driven to rotate, and the scraper 807 scrapes off the foreign matters adhered to the surface of the plate-shaped ceramic membrane 16. At this time, the liquid outlet 3 is opened, and the scraped foreign matters will fall from the liquid outlet 3. This device can facilitate the cleaning of the plate-shaped ceramic membrane 16. The filtration effect is better. When it is necessary to replace the plate-shaped ceramic membrane 16, first rotate the screw sleeve 12 to make the screw sleeve 12 disengage from the threaded hole 14. At this time, the cylinder cover 9 can be disconnected from the first hydraulic cylinder 10. Then, the output end of the second hydraulic cylinder 803 is extended and retracted to lift the connecting plate 806 upward to move, so that a number of scrapers 807 disengage from the surface of the plate-shaped ceramic membrane 16. At this time, the staff pulls the cylinder cover 9 to disengage the plate-shaped ceramic membrane 16 from the inside of the filter cylinder 1. Conversely, it can be installed to replace the plate-shaped ceramic membrane 16.

[0027] The above embodiments of the present utility are merely examples for clearly illustrating the present utility, rather than limiting the implementation modes of the present utility. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is impossible to list all the implementation modes here. Any obvious changes or variations derived from the technical solutions of the present utility still fall within the protection scope of the present utility.
