[0002] MBR membrane assembly, that is, the membrane assembly of membrane bioreactor, is a high-efficiency water treatment equipment that combines biological treatment technology with membrane separation technology. It combines the activated sludge method with membrane separation technologies such as microfiltration, ultrafiltration, and nanofiltration to achieve effective removal of suspended solids, colloids and dissolved organic matter in sewage. It has the advantages of good effluent quality, small footprint, small amount of residual sludge, and simple operation and management. It is widely used in urban sewage treatment, industrial wastewater treatment, and reclaimed water reuse.

[0003] During long-term operation, the membrane material will gradually age due to factors such as oxidation, ultraviolet radiation, and chemical corrosion, resulting in a decline in membrane performance, such as reduced flux and reduced retention rate. In addition, organic matter, microorganisms, suspended solids and other pollutants will accumulate on the membrane surface, and even through cleaning, the original performance cannot be restored, which eventually leads to the need to replace the membrane assembly. The replaced discarded MBR membrane assembly often needs to be placed in a unified manner for subsequent statistics, management and recycling.

[0028] See also Figure 1-8 .

[0029] The fixing device of the waste MBR membrane assembly of the present invention comprises a waste membrane assembly 1 and a fixing assembly 2 for fixing the waste membrane assembly 1, the waste membrane assembly 1 comprises a plurality of membrane bodies 102 and a frame 101 for fixing the plurality of membrane bodies 102, the fixing assembly 2 comprises a shell 3, a first limiting plate 4 slidably arranged in the shell 3 and a second limiting plate 5 elastically arranged in the shell 3, the top opening of the shell 3 is arranged to facilitate the placement of the waste membrane assembly 1, the bottom of the shell 3 is fixedly connected with an electric push rod 8, the protruding end of the electric push rod 8 is fixedly connected to the first limiting plate 4, which is used to adjust the position of the first limiting plate 4, the second limiting plate 5 and the first limiting plate 4 are vertically arranged, and the first limiting plate 4 and the second limiting plate 5 are used to fix the waste membrane assembly 1, such as Figure 7 As shown, in the initial state of the fixed component 2, the first limit plate 4 is close to the wall of the shell 3. When placing the waste membrane component 1, the position of the first limit plate 4 needs to be adjusted according to the size of its frame 101. The spring 13 of the second limit plate 5 should be in an squeezed state after the waste membrane component 1 is placed, otherwise the waste membrane component 1 of this size is not suitable for the fixed component 2.

[0030] In addition, the first limit plate 4 is set in a C shape, the opening height of the opening of the first limit plate 4 is consistent with the height of the second limit plate 5, the bottom of the first limit plate 4 is fixedly connected to the first slider 6, the bottom of the housing 3 is provided with a first slide groove 7 that is adapted to the size of the first slider 6, the electric push rod 8 is set in the first slide groove 7, and the protruding end of the electric push rod 8 is fixedly connected to the first slider 6. Figure 5 or Figure 6 As shown, the opening of the first limiting block 14 leaves space for the second limiting plate 5 to move.

[0031] Among them, the top and bottom of the shell 3 are fixedly connected with a sliding rod 9, and the top and bottom of the first limiting plate 4 are provided with sliding holes 10 that are adapted to the size of the sliding rod 9. The first limiting plate 4 is mounted on the sliding rod 9 through the sliding hole 10. The two sliding rods 9 are used to limit the first limiting plate 4 to keep it stable when moving. Since the bottom of the first limiting plate 4 is limited by the first slider 6 and the first slide groove 7, and its top lacks a limiting component, it is easy to deflect when moving, so a sliding rod 9 is provided to improve the limiting effect.

[0032] Furthermore, multiple springs 13 are fixedly connected to the second limit plate 5, one end of the multiple springs 13 is fixedly connected to the second limit plate 5, and the other end of the multiple springs 13 is fixedly connected to the inner wall surface of the shell 3. The top and bottom of the second limit plate 5 are fixedly connected to two second sliders 11 with a T-shaped cross-section. The shell 3 is provided with a second slide groove 12 that is adapted to the size of the multiple second sliders 11. The second slider 11 and the second slide groove 12 are used to limit the second limit plate 5 so that it remains stable when moving. The setting of the spring 13 enables the waste membrane assembly 1 to have a certain impact resistance during transportation. At the same time, the spring 13 can also limit waste membrane assemblies 1 of various sizes within the elastic range, thereby improving the applicability of the fixed assembly 2.

[0033] In addition, a plurality of limit blocks 14 are fixedly connected to any end face of the housing 3 and any side face adjacent to the end face, and a plurality of limit slots 15 having sizes matching those of the limit blocks 14 are provided on the other end face and the other side face of the housing 3. Figure 1 As shown, when multiple fixing components 2 are placed or transported at the same time, in order to reduce the occupied space, adjacent fixing components 2 should be placed close to each other. After being placed close together, the fixing components 2 can be limited by the limiting action of the limiting block 14 and the limiting groove 15, thereby improving the stability of the fixing components 2.

[0034] When using this device, before placing the waste membrane assembly 1, the first limit plate 4 needs to be located in the initial position, and then the second limit plate 5 is squeezed. After the waste membrane assembly 1 is placed, the second limit plate 5 is released, and then the position of the first limit plate 4 is adjusted by the electric push rod 8. It should be noted that when placing the waste membrane assembly 1, the waste membrane assembly 1 should be located at the diagonal point of the intersection of the first limit plate 4 and the second limit plate 5, so that the two surfaces of the frame 101 are in close contact with the two inner wall surfaces of the shell 3.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
