Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Furthermore, the locking assembly includes a locking card plate 11 and a locking card slot 12. The locking card plate 11 is fixedly connected to the left side of the main outer frame 3. The locking card slot 12 is provided on the surface of the sealing plate 4. The inner wall of the locking card slot 12 is engaged and adapted with the surface of the locking card plate 11. A reinforcing thread groove 13 is provided inside the locking card plate 11 and the locking card slot 12. The inner wall of the reinforcing thread groove 13 is threadedly connected with a fixing screw 14, and the fixing screw 14 is located outside the sealing plate 4. The locking card plate 11 and the locking card slot 12 are used for abutment locking, and then the fixing screw 14 is threadedly rotated and connected into the reinforcing thread groove 13 for secondary locking.

[0027] Furthermore, a guide plate 20 is fixedly connected to the side of the side guard plate 9, and a guide groove 21 is provided on the front and rear sides of the inner wall of the main outer guard frame 3. The inner wall of the guide groove 21 and the surface of the guide plate 20 are slidably connected. Through the arrangement of the guide plate 20 and the guide groove 21, the deflection of the side guard plate 9 and the ejection plate 8 when they are squeezed is reduced.

[0028] Example 2, please refer to Figures 1 to 7 The difference between this embodiment and embodiment 1 is that an elastic pad 15 is fixedly connected to the surface of the inner wall of the sealing plate 4, the surface of the elastic pad 15 is opened as a smooth surface, and the surface of the elastic pad 15 is in contact with the surface of the fixing plate 2. The elastic pad 15 in the inner wall of the sealing plate 4 can clamp the fixing plate 2 on the flat ceramic filter membrane body 1.

[0029] Furthermore, the bottom of the main outer protective frame 3 and the bottom of the sealing plate 4 are both fixedly connected with an anti-skid abutment plate 16, and the top of the main outer protective frame 3 is fixedly connected with a sleeve plate 17, and the inner wall of the sleeve plate 17 and the surface of the anti-skid abutment plate 16 are snap-fitted. The upper surface of the main outer protective frame 3 is fixedly connected with a pressure isolation plate 18, and the surface of the pressure isolation plate 18 is fixedly connected with a tough rope 19. The anti-skid abutment plate 16 and the sleeve plate 17 are arranged so that the upper and lower flat ceramic filter membrane bodies 1 can be docked, fixed and stably stacked. The pressure isolation plate 18 is arranged above the main outer protective frame 3 to play a supporting and pressure-relieving effect, and the tough rope 19 can be used to carry and transport a single flat ceramic filter membrane body 1.

[0030] Working principle: When this kind of ceramic filter membrane is in use, because the overall exterior of the flat ceramic filter membrane body 1 is relatively fragile, in order to ensure the stacking, storage and subsequent smooth transportation of the flat ceramic filter membrane body 1, it is necessary to set protection on the exterior of the flat ceramic filter membrane body 1 to enhance its protective effect, that is, the flat ceramic filter membrane body 1 is pushed into the interior of the main outer protective frame 3, and the guide wheels 5 at the top and bottom of the inner wall of the main outer protective frame 3 can ensure the smooth movement of the flat ceramic filter membrane body 1 in the main outer protective frame 3, and a wear-resistant smooth membrane 6 is added to the guide wheel 5 to contact the upper and lower surfaces of the flat ceramic filter membrane body 1, reducing the wear on the upper and lower surfaces of the flat ceramic filter membrane body 1. When the flat ceramic filter membrane body 1 moves to the right side of the inner wall of the main outer protective frame 3, the push-out plate 8 and the side guard plate 9 can be used to abut and constrain the flat ceramic filter membrane body 1. Under the action of the abutment cushion 10, the circumferential pressure on the flat ceramic filter membrane body 1 is reduced, and the guide plate 20 and the guide groove are used. The setting of 21 reduces the situation that the side guard plate 9 and the push-out plate 8 are deflected when they are squeezed. After the setting of the spring telescopic rod 7, the flat ceramic filter membrane body 1 can be elastically pushed out and taken out from the inside of the main outer protective frame 3. When the flat ceramic filter membrane body 1 needs to be completely packaged externally, the locking card plate 11 and the locking card groove 12 can be used for abutment and locking, and then the firm screw 14 is threaded and connected into the reinforcement thread groove 13 for secondary locking, and the elastic pad 15 in the inner wall of the sealing plate 4 can clamp the fixing plate 2 on the flat ceramic filter membrane body 1. Through the setting of the anti-slip abutment plate 16 and the sleeve plate 17, the upper and lower flat ceramic filter membrane bodies 1 can be docked, fixed and stably stacked. A pressure isolation plate 18 is arranged above the main outer protective frame 3 to support and relieve pressure, and a single flat ceramic filter membrane body 1 can be carried and transported through the set toughness rope 19, which ensures the external derivative protection of the flat ceramic filter membrane body 1 and the stable stacking effect.
