Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an MRB membrane tank for wastewater treatment. Background Technology

[0002] MBR (Membrane Bioreactor) is a novel wastewater treatment process that combines a bioreactor with a membrane separation process. Microorganisms and macromolecular solutes are retained by the membrane, thus replacing the sedimentation tank to complete the separation process from the treated effluent. Its biggest feature is that it uses membrane modules to replace the secondary sedimentation tank in traditional biological treatment.

[0003] Currently, common wastewater treatment MRB membrane reactors typically utilize membrane modules composed of multiple MRB membranes to treat wastewater. However, when one MRB membrane fails and needs replacement, the entire membrane module must be disassembled, and each MRB membrane must be replaced individually. This makes it impossible to replace individual MRB membranes, resulting in high costs and low practicality. In view of this, this paper proposes an improved MRB membrane bioreactor for wastewater treatment to address these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background art by proposing an MRB membrane tank for wastewater treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An MRB membrane tank for wastewater treatment, comprising:

[0007] Treatment pool;

[0008] Two pipes are fixedly connected to both sides of the treatment pool;

[0009] A connecting rod is slidably inserted into the top of the treatment tank. Multiple portal frames are detachably connected to the bottom of the connecting rod, and the front and rear sides of the portal frames are attached to the inside of the treatment tank. An MRB membrane is fixedly installed in each portal frame.

[0010] Multiple connecting components are respectively placed on top of multiple portal frames and used to fix the portal frames to the lower side of the connecting rod;

[0011] Two locking components are respectively placed at both ends of the connecting rod and are used to fix the connecting rod to the top of the treatment pool.

[0012] Preferably, the locking assembly includes a slot formed at the top of the treatment pool, and the slot is slidably connected to or separated from the connecting rod, the end of the connecting rod being threaded with a threaded plate; the opposite sides of the two threaded plates abut against the two sides of the treatment pool respectively.

[0013] Preferably, the connecting assembly includes a fixing block fixedly installed on the top of the portal frame, a screw threaded through the end of the fixing block and slidingly passing through the connecting rod, a knob fixedly installed at the other end of the screw, positioning plates abutting both sides of the portal frame and fixedly fitted onto the surface of the connecting rod.

[0014] Preferably, each of the gantry frames has two blocks attached to both sides, and the blocks are fixedly installed at the bottom of the treatment pool.

[0015] Preferably, the surface of the connecting rod is provided with multiple insertion holes, and the multiple insertion holes are respectively inserted into or separated from multiple screws.

[0016] Compared with existing technologies, the advantages of the MRB membrane tank for wastewater treatment provided by this utility model are as follows:

[0017] This invention involves rotating the threaded plate away from the treatment tank, then pulling up the connecting rod and rotating the knob corresponding to the MRB membrane that needs to be replaced. This causes the screw to spiral away from the connecting rod until it disengages from the insertion hole on the connecting rod. The gantry frame can then be removed from the connecting rod for individual replacement, reducing operating costs and improving the practicality of the device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1 to 5 An MRB membrane tank for wastewater treatment, comprising:

[0026] Treatment pool 1; two pipes 2, which are fixedly connected to the two sides of the treatment pool 1 respectively; a connecting rod 3, which is slidably inserted into the top of the treatment pool 1; multiple gantry frames 4 are detachably connected to the bottom of the connecting rod 3; the front and rear sides of the gantry frames 4 are attached to the inside of the treatment pool 1; an MRB membrane 5 is fixedly installed inside each gantry frame 4; two blocks 8 are attached to both sides of each gantry frame 4; and the blocks 8 are fixedly installed at the bottom inside the treatment pool 1 to ensure the stability of each gantry frame 4 placed in the treatment pool 1.

[0027] Multiple connecting components are respectively placed on the top of multiple portal frames 4 and used to fix the portal frames 4 to the lower side of the connecting rod 3. The connecting components include a fixing block 10 fixedly installed on the top of the portal frame 4. The end of the fixing block 10 is threaded through a screw 11, and the screw 11 slides through the connecting rod 3. Multiple insertion holes are opened on the surface of the connecting rod 3, and the multiple insertion holes are respectively inserted into or separated from the multiple screws 11.

[0028] A knob 12 is fixedly installed at the other end of the screw 11. Positioning plates 9 are attached to both sides of the gantry frame 4, and the positioning plates 9 are fixedly fitted onto the surface of the connecting rod 3. Through the cooperation of the two positioning plates 9, the gantry frame 4 can be clamped between the two positioning plates 9, which helps to fix the gantry frame 4 and the connecting rod 3.

[0029] Two locking components are respectively placed at both ends of the connecting rod 3 and used to fix the connecting rod 3 to the top of the treatment pool 1. The locking components include slots 6 opened on the top of the treatment pool 1, and the slots 6 are slidably connected to or separated from the connecting rod 3. The end of the connecting rod 3 is threaded with a threaded plate 7. The opposite sides of the two threaded plates 7 are respectively pressed against the two sides of the treatment pool 1. When the two threaded plates 7 are rotated, the connecting rod 3 can be fixed to the treatment pool 1 by pressing the opposite sides of the two threaded plates 7 against the two sides of the treatment pool 1.

[0030] The working principle of this utility model is as follows:

[0031] When in use, wastewater is introduced into one of the pipes 2, and then passes through each MRB membrane 5 in sequence for treatment. Finally, qualified, pollution-free water is discharged from the other pipe 2.

[0032] When the MRB membrane 5 needs to be replaced, first rotate the threaded plate 7 away from the treatment tank 1, then pull up the connecting rod 3 and turn the knob 12 corresponding to the MRB membrane 5 that needs to be replaced, so that the screw 11 moves spirally away from the connecting rod 3 until the screw 11 disengages from the insertion hole on the connecting rod 3. Then the gantry frame 4 can be removed from the connecting rod 3 for individual replacement.

[0033] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
