Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to an installation structure for an MBR membrane module. Background Technology

[0002] The solid-liquid separation membrane modules used downstream of the MBR process are used to filter water that has undergone aerobic and anaerobic treatment and to retain the activated sludge carried in it. They have advantages such as high efficiency in solid-liquid separation, low residual sludge production, and small footprint, and are widely used in the water treatment field.

[0003] Currently, MBR membrane modules are fixedly suspended in the treatment container. During operation, high-intensity aeration by blowers is required to remove the activated sludge adsorbed on the surface of the membrane modules, resulting in high power consumption of the MBR process.

[0004] Therefore, how to effectively reduce the operating power of MBR process is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an installation structure for MBR membrane modules. This structure is simple and has low modification costs. Through rapid reciprocating motion, the membrane module is flushed with water, thereby removing the activated sludge adsorbed on the surface of the membrane module and effectively reducing energy consumption.

[0006] The technical solution of this utility model is: an installation structure for an MBR membrane module, including a processing container and a membrane module disposed in the processing container, and a suspension mechanism. The processing container is provided with a lifting frame located above the membrane module, and the lifting frame is driven by a reciprocating vibrator to reciprocate in the horizontal direction. The suspension mechanism includes four arms, the upper ends of which are respectively hinged to the four corners of the lifting frame and rotate in the reciprocating direction of the lifting frame. The lower ends of which are respectively hinged to the four corners of the top frame of the membrane module and rotate in the reciprocating direction of the lifting frame, thus forming the installation structure for the MBR membrane module.

[0007] It also includes a limiting mechanism, which includes at least one limiting rod. At least one end of the limiting rod is provided with a strip-shaped limiting hole extending along the length direction of the limiting rod. One end of the limiting rod is hinged to the hoisting frame and rotates along the reciprocating motion direction of the hoisting frame. The other end is hinged to the top frame of the membrane assembly through the strip-shaped limiting hole.

[0008] Both ends of the limiting rod are provided with strip-shaped limiting holes extending along the length of the limiting rod, and both ends are respectively hinged to the hoisting frame and the top frame of the membrane module through the strip-shaped limiting holes.

[0009] The number of limiting rods is four, with two rods forming a group, located on both sides of the membrane module. The upper ends of the two limiting rods in each group are hinged to both ends of the hoisting frame, and the lower ends of the two limiting rods are hinged to the middle of the top frame of the membrane module through strip-shaped limiting holes.

[0010] The reciprocating vibrator includes two first reciprocating vibrators and two second reciprocating vibrators. The two first reciprocating vibrators are fixed on one side of the inner wall of the processing container and are spaced apart. The two second reciprocating vibrators are fixed on the opposite side of the inner wall of the processing container and are spaced apart. The two ends of the long side of the hoisting frame are respectively installed between the corresponding first reciprocating vibrators and second reciprocating vibrators, so that the hoisting frame moves horizontally reciprocating along the width direction.

[0011] The processing container has mounting platforms on both inner walls, and the first reciprocating vibrator and the second reciprocating vibrator are respectively mounted on the corresponding mounting platforms.

[0012] The above technical solution has the following beneficial effects:

[0013] 1. The installation structure of the MBR membrane module includes a treatment container and a membrane module disposed within the treatment container. Both the treatment container and the membrane module are existing conventional equipment. It also includes a suspension mechanism. A lifting frame is provided in the treatment container, located above the membrane module, and the lifting frame is driven by a reciprocating vibrator to reciprocate horizontally; that is, the lifting frame moves horizontally above the membrane module. The suspension mechanism includes four booms. The upper ends of each boom are hinged to the four corners of the lifting frame and rotate in the reciprocating direction of the lifting frame. The lower ends of each boom are hinged to the four corners of the top frame of the membrane module and rotate in the reciprocating direction of the lifting frame. Together, they form the installation structure of the MBR membrane module. When the lifting frame is driven by a reciprocating vibrator to reciprocate horizontally, the booms drive the membrane module to reciprocate horizontally and have a small reciprocating motion in the height direction. During the reciprocating motion, the membrane module and the water in the treatment container are flushed, achieving the purpose of removing the activated sludge adsorbed on the surface of the membrane module. Since the two ends of the booms are hinged to the lifting frame and the membrane module, rather than fixedly connected, the movement of the membrane module has a lag, and the running resistance of the lifting frame is significantly reduced. It can also effectively reduce the shear force borne by the booms and ensure the service life of the booms.

[0014] 2. It also includes a limiting mechanism, which includes at least one limiting rod. At least one end of the limiting rod is provided with a strip-shaped limiting hole extending along the length of the limiting rod. One end of the limiting rod is hinged to the hoisting frame and rotates along the reciprocating motion direction of the hoisting frame. The other end is hinged to the top frame of the membrane module through the strip-shaped limiting hole. The horizontal movement range of the membrane module is limited by the strip-shaped limiting hole. While ensuring that the reciprocating motion of the membrane module achieves water scouring of the surface, it can maintain the overall stability of the membrane module and avoid large-scale shaking of the membrane module.

[0015] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

Detailed Implementation

[0020] See Figures 1 to 3This is a specific embodiment of an MBR membrane module installation structure. The MBR membrane module installation structure includes a treatment container 1 and a membrane module 2 disposed within the treatment container. Both the treatment container 1 and the membrane module are commercially available conventional equipment. It also includes a suspension mechanism 3. A lifting frame 4 is provided in the treatment container 1, located above the membrane module 2, and the lifting frame 4 is driven by a reciprocating vibrator to reciprocate horizontally. In this embodiment, installation platforms 11 are provided on the inner walls of both sides of the treatment container 1. Specifically, the installation platforms can be formed by setting horizontally extending angle steel, or horizontally extending rectangular tubes. The reciprocating vibrator includes two first reciprocating vibrators 9 and two second reciprocating vibrators 10. The reciprocating vibrators can be conventional reciprocating vibrators used in the chemical industry, such as... A piston-type reciprocating vibrator has its connector extending perpendicularly outward from the piston's housing, reciprocating rapidly along the piston's extension direction. Two first reciprocating vibrators 9 are fixed to a mounting platform on one side of the inner wall of the processing container 1, spaced apart. Two second reciprocating vibrators 10 are fixed to a mounting platform on the opposite side of the inner wall of the processing container 1, also spaced apart. The long side ends of the lifting frame 4 are respectively installed between the corresponding first reciprocating vibrators 9 and second reciprocating vibrators 10, and fixed to the connector, allowing the lifting frame 4 to reciprocate horizontally along its width. The suspension mechanism 3 includes four booms 5, the upper ends of which are hinged to the four corners of the lifting frame 4 and rotate along the reciprocating direction of the lifting frame 4. The lower ends of each boom 5 are hinged to the four corners of the top frame of the membrane module 2 and rotate along the reciprocating direction of the lifting frame 4, forming the installation structure of the MBR membrane module.

[0021] To limit the vibration amplitude of the membrane module, a limiting mechanism 6 is also provided. The limiting mechanism 6 includes four limiting rods 7. Both ends of each limiting rod 7 are provided with strip-shaped limiting holes 8 extending along the length of the limiting rod. Two limiting rods form a group, which are located on both sides of the membrane module 2. The upper ends of the two limiting rods in each group are respectively hinged to both ends of the hoisting frame 4, and the lower ends of the two limiting rods 7 are hinged to the middle of the top frame of the membrane module through the strip-shaped limiting holes 8.

[0022] The working principle of this utility model is as follows: when the hoisting frame is driven by the reciprocating vibrator to reciprocate in the horizontal direction, the boom drives the membrane module to reciprocate in the horizontal direction and has a small reciprocating motion in the height direction. During the reciprocating motion, the membrane module and the water in the treatment container are flushed, thereby achieving the purpose of removing the activated sludge adsorbed on the surface of the membrane module.

[0023] According to the applicant's verification, the vibration frequency of the hoisting frame is controlled at 15 times / min, and the vibration interval is 10 minutes of operation for every 110 minutes of operation. Compared with the transmission aeration removal method, this saves about 50%-70% of energy.
