An environmentally friendly MBR membrane device for sewage treatment relates to the technical field of sewage treatment, including a main template and a first template. A third template is arranged on the outside of the first template, and several groups of second templates are arranged between the third template and the first template. Four groups of first sliders are fixedly connected to the outer side of the main template near the top, and four groups of second sliders are fixedly connected to the outer side of the first template near the top. Four groups of third sliders are fixedly connected to the outer side of several groups of the second templates near the top, and the main template is located on the inner side of the first template.

It can quickly flush several groups of MBR membranes and has the function of efficiently cleaning impurities, which is beneficial to the next sewage treatment process.

[0003] In this patent, when adjusting the height of the top frame rod, multiple bolts need to be pulled out one by one to release the restrictions on multiple connected vertical rods, which is rather troublesome. In addition, the top frame rod does not have the function of moving up and down, and needs to be lifted manually. It takes multiple people to lift the top frame rod, which wastes manpower.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 3 An environmentally friendly MBR membrane device for sewage treatment comprises a lower frame 1 and an upper frame 11, a plurality of first water pipes 2 are arranged at equal intervals on the lower frame 1, a plurality of second water pipes 12 are arranged at equal intervals on the upper frame 11, a membrane body 3 is arranged between each group of upper and lower corresponding first water pipes 2 and second water pipes 12, and a plurality of groups of membrane bodies 3 cooperate with the first water pipes 2 and the second water pipes 12 to treat sewage;

[0024] The first support 15 and the second support 16 are fixedly installed on the left and right sides of the lower frame 1 and the upper frame 11. The upper end of the first support 15 is fixedly installed with a vertical rod 13. The two vertical rods 13 are both sleeved with a slidable sliding sleeve 14. The sliding sleeve 14 is fixedly connected to the upper frame 11 and plays a guiding role to ensure that the upper frame 11 can move stably.

[0025] The upper end of the second support 16 is rotatably connected with a screw rod 4, and the two screw rods 4 are connected by a transmission assembly, which is two transmission wheels 10 and a transmission belt. The two transmission wheels 10 are coaxially fixed to the two screw rods 4 respectively;

[0026] The upper ends of the adjacent vertical rods 13 and the screw rods 4 are fixedly mounted with a top plate 7, and two connecting plates 8 for improving stability are fixedly mounted between the two top plates 7 to connect the two top plates 7 and increase the stability of the top plates 7;

[0027] A control mechanism for controlling the height adjustment of the upper frame 11 is provided at the upper end of one of the top plates 7 , and the control mechanism includes a mounting plate 5 fixedly mounted on the upper end of the top plate 7 , and a drive motor 6 is fixedly mounted on the upper end of the mounting plate 5 , and the drive motor 6 is coaxially fixed with the screw 4 .

[0028] Working principle:

[0029] During installation, the drive motor 6 is started, and the output shaft of the drive motor 6 rotates to drive the screw rod 4 to rotate, and then the two screw rods 4 are synchronously rotated through the cooperation of the transmission wheel 10 and the transmission belt. The rotation of the screw rod 4 enables the threaded sleeve 9 to move up and down, so that the upper frame 11 moves up and down. At the same time, the upper frame 11 moves linearly along the vertical rod 13 through the sliding sleeve 14, ensuring the stability of the movement;

[0030] When the distance between the upper frame 11 and the lower frame 1 is the same as the length of the membrane 3, the upper frame 11 stops moving up and down. At this time, membranes 3 of different lengths can be installed on the device, which improves the applicability of the device and can meet the installation requirements of membranes 3 of different lengths.
