Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] like Figure 1-4 As shown, a submersible MBR membrane module rotation anti-buoyancy device includes at least one vertically arranged membrane module guide rod 1, an anti-buoyancy base 2 mounted on the membrane module guide rod, a rotatable rotator 3 rotatably connected to the anti-buoyancy base, the side of the rotator abutting against the outer wall of the membrane module guide rod, a control rope assembly 4 for pulling the rotator to rotate provided on the anti-buoyancy base, the membrane module guide rod being distributed along the outer periphery of the membrane module, the membrane module being slidably connected to the membrane module guide rod, and the membrane module including a membrane module body 5, the outer wall of the membrane module body having... A sliding block 6 is provided, and a sliding groove 7 is provided on the sliding block corresponding to the membrane module guide rod. The sliding block is directly opposite the rotator. In use, when it is necessary to lower the membrane module, first pull the rotator open by controlling the rope assembly, then align the sliding groove on the membrane module with each membrane module guide rod and lower it. After that, release the control rope assembly, and the rotator will reset. At this time, the rotator is directly above the sliding block of the membrane module. Even if the submerged MBR membrane module becomes unstable or floats due to aeration in the membrane module corridor, it will be limited by the obstruction of the rotator.

[0024] In this embodiment, for a reasonable design, the anti-buoyancy base includes connecting plates 8 arranged symmetrically on the upper and lower sides. One end of the two connecting plates is connected by a protective plate 9, and the other end of the two connecting plates is welded to the membrane module guide rod. The welding end of the connecting plate is provided with an arc-shaped welding port corresponding to the membrane module guide rod, which facilitates the alignment of the connecting plate and the membrane module guide rod before welding. At the same time, the welding point of the connecting plate on the membrane module guide rod is located in the groove area of ​​the sliding groove or in an area that does not interfere with the sliding block.

[0025] In this embodiment, to achieve the rotation of the rotator, the rotator includes a rotating fixing block 10, which is a shell structure. The rotating fixing block has a semi-circular relief groove 11 on the side of the membrane module guide rod that is in contact with the membrane module guide rod. The upper and lower sides of the rotating fixing block have symmetrically opened rotating holes 12 that communicate with the inner cavity of the rotating fixing block. A rotating shaft 13 is rotatably connected between the two rotating holes. The two ends of the rotating shaft extend out of the corresponding rotating holes and are rotatably connected to the connecting plate on the same side. Specifically, the rotating holes are located at one of the two corners of the side of the rotating fixing block with the semi-circular relief groove. The diameter of the semi-circular relief groove is not less than the diameter of the membrane module guide rod. Under normal conditions, the semi-circular relief groove of the rotating fixing block should abut against the outer wall of the membrane module guide rod. When the control rope assembly is pulled open, the rotating fixing block rotates away from the top of the sliding block, which facilitates the replacement of the membrane module.

[0026] In this embodiment, in order to enable the semi-circular clearance groove of the rotating fixing block to abut against the outer wall of the membrane module guide rod under normal conditions and the rotating fixing block to self-reset when the control rope assembly is released, a torsion spring 14 is sleeved on the shaft section of the rotating fixing block. One end of the torsion spring is fixed to the inner wall of the rotating fixing block, and the other end is fixed to the rotating shaft.

[0027] In this embodiment, to achieve the disengagement of the control rope assembly from the rotator, the control rope assembly includes a traction rope 15, one end of which is fixed to the rotator. The fixing point of the traction rope is located on the side of the rotator away from the rotation connection point. The control rope assembly also includes a traction guide rod 16, which is fixed to the upper connecting plate. A rope loop 17 for the traction rope to pass through is provided at the end of the traction guide rod. The fixing point of the traction guide rod is located outside the rotation connection point of the rotator. The rope loop is set in the direction of the rotator's outward rotation. In use, by pulling the traction rope, the end of the traction rope drives the rotator to move towards the rope loop, thereby achieving the disengagement of the rotator from the membrane module guide rod.
