[0029] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0030] This application discloses a ceramic membrane sealing assembly. (Refer to...) Figure 1-9 A ceramic membrane sealing assembly includes a sealing housing 1, a ceramic membrane assembly 2, and a sealing cap assembly 3. The ceramic membrane assembly 2 is inserted into the interior of the sealing housing 1. A connecting mechanism is installed on the outer wall of the sealing housing 1 near the top. The sealing cap assembly 3 is installed on the top of the sealing housing 1 through the connecting mechanism.
[0031] The ceramic membrane module 2 includes a lower fixing seat 22, a ceramic membrane tube 23 and an upper fixing seat 21. Multiple ceramic membrane tubes 23 are installed between the lower fixing seat 22 and the upper fixing seat 21. The top outer wall of the upper fixing seat 21 is provided with a tight groove 211 and the top inner wall is provided with a sealing groove 212.
[0032] The bottom outer wall of the sealing cover assembly 3 is designed in a stepped manner. A sealing gasket 34 is provided on the bottom outer wall. The sealing gasket 34 is tightly engaged with the sealing groove 212. A hollow rubber ring 35 is provided on the bottom outer wall of the sealing cover assembly 3 above the sealing gasket 34. The hollow rubber ring 35 is tightly engaged with the sealing groove 211. Both the sealing gasket 34 and the hollow rubber ring 35 are made of elastic high-temperature resistant material, which is fluororubber.
[0033] The connecting mechanism includes a collar 13 rotatably connected to the outer wall of the sealing housing 1 near the top, an external gear ring 14 fixedly connected to the outer wall of the collar 13, and a plurality of screws 11 rotatably connected to the top outer wall of the sealing housing 1 via bearings. The plurality of screws 11 are evenly distributed in a circumferential array at equal intervals, and gears 12 are fixedly connected to the bottom ends of the plurality of screws 11. The plurality of gears 12 mesh with the external gear ring 14.
[0034] The sealing cap assembly 3 has multiple screw holes 31 on its outer wall near the edge. The multiple screw holes 31 correspond to multiple screws 11, and the screws 11 are threadedly connected to the inner wall of the screw holes 31.
[0035] The sealing cap assembly 3 also includes a liquid inlet 32 and a connecting flange 33. The liquid inlet 32 is located on the middle outer wall of the sealing cap assembly 3, and the connecting flange 33 is fixedly connected to the top outer wall of the liquid inlet 32.
[0036] Multiple positioning blocks 16 are fixedly connected to the bottom inner wall of the sealed housing 1, and multiple positioning grooves 221 are opened on the bottom outer wall of the lower fixing seat 22. The multiple positioning grooves 221 are correspondingly engaged with the multiple positioning blocks 16.
[0037] A drain outlet 4 is provided on the outer wall near the bottom of the sealed housing 1. The drain outlet 4 is connected to the interior of the sealed housing 1, and a valve 41 is installed on the outer wall of the drain outlet 4.
[0038] Multiple actuating rods 15 are fixedly connected to the bottom outer wall of the collar 13, and the multiple actuating rods 15 are evenly distributed in a circumferential array at equal intervals.
[0039] Sealing rings 24 are provided at the connection points between the two ends of the ceramic membrane tube 23 and the lower fixing seat 22 and the upper fixing seat 21.
[0040] The implementation principle of a ceramic membrane sealing assembly in this application embodiment is as follows: First, when assembling the ceramic membrane assembly 2, the lower fixing seat 22 and the upper fixing seat 21 are connected to the two ends of multiple ceramic membrane tubes 23. The sealing ring 24 can seal the connection between the two ends of the ceramic membrane tubes 23 to ensure the sealing performance of the ceramic membrane tubes 23. Then, the assembled ceramic membrane assembly 2 is inserted into the sealing shell 1.
[0041] When the ceramic membrane assembly 2 enters the sealed housing 1, its lower fixing seat 22 at the bottom enters the bottom inner wall of the sealed housing 1. The multiple positioning grooves 221 on the outer wall of the lower fixing seat 22 engage with the multiple positioning blocks 16 at the bottom of the sealed housing 1 to position the ceramic membrane assembly 2, making it difficult for the ceramic membrane assembly 2 to shake inside the sealed housing 1 and improving installation stability.
[0042] Next, align the multiple screw holes 31 on the outer wall of the sealing cap assembly 3 with the multiple screws 11 on the top of the sealing housing 1. Rotate the collar 13 by turning the lever 15. When the collar 13 rotates, it drives the outer gear ring 14 to rotate. The rotation of the outer gear ring 14 drives the multiple gears 12 that mesh with it to rotate. The multiple gears 12 then drive the multiple screws 11 to rotate synchronously in the same direction. Then, the multiple screws 11 are screwed into the multiple screw holes 31, thereby fixing the sealing cap assembly 3 to the top of the sealing housing 1. As the multiple screws 11 continue to rotate, the bottom outer wall of the sealing cap assembly 3 continues to enter the sealing housing 1. At this time, the sealing gasket 34 and the hollow rubber ring 35 at the bottom of the sealing cap assembly 3 are tightly engaged with the sealing groove 212 and the tight groove 211 on the top of the upper fixing seat 21, respectively, which can effectively fill the tiny gap between them and prevent fluid from leaking from the connection.
[0043] When maintenance or replacement of the ceramic membrane is required, the connecting mechanism can be easily rotated out of multiple screw holes 31 in the reverse direction. Simply rotate the collar 13 in the reverse direction using multiple levers 15. The collar 13 drives the external gear ring 14 to rotate in the reverse direction, which in turn drives multiple gears 12 meshing with it to rotate in the reverse direction. The multiple gears 12 then drive multiple screws 11 to rotate in the reverse direction within the screw holes 31. This allows for easy disassembly of the sealing cover assembly 3 and removal of the ceramic membrane assembly 2, greatly reducing maintenance costs and time, and improving the maintainability and flexibility of the equipment.
