Specific embodiments

[0021] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Referring to Figures 1-4 , a sewage treatment device of an MBR membrane bioreactor includes a support frame 1 and an automatic adjustment mechanism 2. A chute 3 is provided inside the top frame of the support frame 1. Seven upper support rods 4 are slidably connected between the upper surfaces of the two side chutes 3. A sliding rod 5 and a threaded rod 6 are respectively fixedly connected above the two ends of the upper support rod 4 in the chute 3. The upper surface of one end of the upper support rod 4 close to the sliding rod 5 is fixedly connected with a sliding seat 7, and the sliding seat 7 is slidably sleeved on the sliding rod 5. One end of the upper support rod 4 close to the threaded rod 6 is threadedly connected to the threaded rod 6 through the automatic adjustment mechanism 2;

[0023] The automatic adjustment mechanism 2 includes a rotating motor 8 fixedly connected to the inner side of the upper surface of the upper support rod 4 close to the threaded rod 6. The outer end of the output rotating shaft of the rotating motor 8 is fixedly connected with a driving gear 9. A driven gear 10 meshing with the driving gear 9 is threadedly connected to the threaded rod 6 at a position close to the driving gear 9. One side of the driven gear 10 close to the rotating motor 8 is fixedly connected with a sleeve 11 sleeved on the threaded rod 6. One end of the sleeve 11 away from the driven gear 10 is fixedly connected with a raised ring. Two fixing plates 12 are fixedly connected to the surface of the upper support rod 4 directly below the threaded rod 6 on both sides of the raised ring. Both sides of the raised ring on the sleeve 11 are in contact with the fixing plates 12. A through hole matching the sleeve 11 is opened at the upper end of the fixing plate 12 close to the driven gear 10, and the sleeve 11 is rotatably connected to the through hole;

[0024] By installing an automatic adjustment mechanism 2 at one end of the upper support rod 4 and a sliding seat 7 and a sliding rod 5 at the other end, the position of the upper support rod 4 on the support frame 1 can be automatically adjusted, greatly improving its adjustment efficiency. Since a threaded connection is provided in the automatic adjustment mechanism 2, the upper support rod 4 can be adjusted to any position, thereby improving its adjustment accuracy. The rotation motors 8 on each upper support rod 4 can be separately controlled by using a PLC multi-channel controller to adjust the positions of the seven upper support rods 4 respectively to achieve precise automatic adjustment;

[0025] Both ends of the lower surface of the seven upper support rods 4 are rotatably connected with connecting rods 13. The bottom ends of the connecting rods 13 on each upper support rod 4 penetrate and are threadedly connected with lower support rods 14. The bottom surfaces of the lower support rods 14 are all attached to the inner wall of the lower end of the support frame 1, which is convenient for supporting the seven lower support rods 14. A hexagonal prism protrusion block 15 is fixedly connected to the middle position of the surface of the connecting rod 13, which is convenient for the user to rotate several connecting rods 13 by using a wrench, so as to facilitate the adjustment of the distance between the upper support rod 4 and the lower support rod 14. Corresponding grooves 16 are provided on the opposite surfaces of the upper support rod 4 and the lower support rod 14, and several tubular membranes 17 are fixedly connected between the upper and lower grooves 16. Cross plates 18 are fixedly connected to both sides of the sliding rod 5 and the threaded rod 6 on the top surface of the support frame 1.

[0026] The functional principle of the present utility model can be elaborated through the following operation methods:

[0027] During use, the upper support rod 4 in the top chute 3 of the support frame 1 can automatically adjust its position in the chute 3 through the cooperation of the automatic adjustment mechanism 2 and the sliding rod 5 and the sliding seat 7 provided at its two ends respectively. During adjustment, the rotation motor 8 is driven to make its output shaft rotate. The output shaft drives the driving gear 9 to rotate. The driving gear 9 makes the driven gear 10 rotate through meshing. A sleeve 11 is fixedly connected to the driven gear 10. Two fixing plates 12 are fixedly connected to one end of the upper support rod 4. One end of the sleeve 11 is rotationally clamped between the two fixing plates 12 through a raised ring. Since the driven gear 10 rotates and is threadedly connected with the threaded rod 6, the sleeve 11 is driven to move along the threaded rod 6, and then the upper support rod 4 is driven to move along the threaded rod 6 in the chute 3, realizing the automatic adjustment of the position of the support rod 4. Compared with manual adjustment, its adjustment efficiency is greatly improved;

[0028] The threaded connection provided in the automatic adjustment mechanism 2 enables the upper support rod 4 to be adjusted to any position, improving its adjustment accuracy. By using a PLC multi-channel controller to separately control the rotation motors 8 on each upper support rod 4, the positions of the seven upper support rods 4 are adjusted respectively to achieve precise automatic adjustment, and then the high-efficiency and high-precision adjustment of the position of the tubular membrane 17 in the device is realized.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
