Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a submerged membrane bioreactor device. Background Technology

[0002] Membrane bioreactors (MBRs) are novel wastewater treatment systems that organically combine membrane separation technology and biological treatment technology. A patent with authorization announcement number CN211035394U, entitled "A Novel Submerged Membrane Bioreactor Component," describes a structure comprising a fixed frame, an equidistant adjustment device, a chute, and a slider. This novel submerged MBR component involves placing the equidistant adjustment device inside the bottom of the fixed frame. Applying force to a handwheel and rotating it clockwise causes the handwheel to rotate a lead screw on a first and second fixed plate. This, in turn, rotates the small and large threads on the lead screw, causing the first ball bearing to engage with the small thread and the second ball bearing with the large thread. This allows the first ball bearing to drive the MBR membrane to slide slowly in the opposite direction, while the second ball bearing drives it to slide quickly in the opposite direction, achieving equidistant adjustment of the membrane spacing. The system is easy to operate and highly mobile. However, in actual use, impurities in the wastewater tend to adhere to the lead screw, small thread, and large thread of this new submerged membrane bioreactor assembly, affecting regulation. The MBR membrane is also difficult to disassemble after installation, which in turn makes it difficult to replace the MBR membrane. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an immersion membrane bioreactor device.

[0004] The technical solution adopted by this utility model to solve its technical problem is an immersion membrane bioreactor device, including a support and an outer frame.

Screw holes adapted to the adjusting bolts are provided on each slide. Multiple slots adapted to the adjusting bolts are provided on both sides of the support.

[0005] By adopting the above technical solution, loosen the adjusting bolts on both sides of the outer frame, slide the outer frame, and let the slide block slide on the bracket. After adjusting the distance between two adjacent outer frames, screw the ends of the adjusting bolts on both sides of the outer frame into the slots on both sides of the bracket to facilitate adjusting the distance between the two adjacent outer frames as needed. When the filter membrane needs to be replaced, loosen the limiting bolts on both sides of the outer frame, and let the ends of the limiting bolts come out of the slots on both sides of the outer frame. Lift the outer frame to remove the outer frame, guide tube, and filter membrane together from the bracket for replacement. During installation, place both sides of the outer frame in the two slide blocks and screw the ends of the limiting bolts into the slots on both sides of the outer frame to facilitate the installation of the outer frame.

[0006] Specifically, each of the conduits has a telescopic tube threaded to one end, and the support has a drain pipe with one end closed and two support mechanisms on one side. The end of each telescopic tube away from the conduit is threaded to the drain pipe. Both ends of each telescopic tube are fitted with sealing rings, and one end of the drain pipe is provided with internal threads.

[0007] By adopting the above technical solution, one end of the telescopic pipe is threadedly connected to the conduit, which facilitates the separation of the conduit and the telescopic pipe. The other end of the telescopic pipe, which is away from the conduit, is threadedly connected to the drain pipe, which facilitates the removal and replacement of the telescopic pipe.

[0008] Specifically, the support mechanism includes a first locking block, a locking bolt, and a second locking block. One end of the first locking block is connected to the bracket, and both the first and second locking blocks are provided with two screw holes that are adapted to the locking bolt.

[0009] By adopting the above technical solution, the first locking block, the second locking block, and the locking bolt are designed to facilitate the fixing or disassembly of the drain pipe.

[0010] Specifically, both the first and second card blocks have protective pads fixed inside.

[0011] By adopting the above technical solution, the protective pad can prevent the first and second clamping blocks from pinching and damaging the drain pipe.

[0012] Specifically, each of the outer frames has a slider integrally formed at its bottom end, a support plate is fixed inside the bracket, and a groove for the slider to slide is provided at the top of the support plate.

[0013] By adopting the above technical solution, the setting of the support plate, slider and the groove at the top of the support plate can improve the stability of the outer frame.

[0014] The beneficial effects of this utility model are:
