Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an adjustable vibrating MBR membrane device. Background Technology

[0002] Fouling of membrane modules is a key factor limiting their operating costs and efficiency. Using mechanical vibration to replace or assist aeration and flushing is an effective anti-fouling technology. Existing technologies, such as CN117964101A, disclose a device that drives a membrane frame to reciprocate linearly on a frame via a crankshaft connecting rod mechanism. However, such devices still have limitations in practical applications: First, the frame and membrane frame are often integrated or have a fixed height. The depth of the membrane tank varies depending on the treatment scale and process selection, but the membrane module can only function properly if it is completely submerged in the mixed liquor. If the liquid level drops below the top of the membrane fibers due to commissioning, maintenance, or fluctuations in water volume, the membrane module will be exposed to air, not only losing its filtration function but also potentially causing irreversible clogging and damage due to the drying of the membrane fibers. Fixed-height vibration devices cannot adapt to membrane tanks of different depths, have poor versatility, and pose operational risks. Therefore, the purpose of this utility model is to provide an adjustable vibrating MBR membrane device to solve the problem in the prior art where the membrane frame height is fixed and cannot be adapted to different membrane pool depths and liquid level fluctuations, which may lead to membrane module exposure and damage. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable vibrating MBR membrane device.

[0004] The innovation of this utility model lies in the addition of a height adjustment component between the hanger that is slidably connected to the mounting base and the membrane frame used to install the membrane module. This enables the vertical height of the membrane frame relative to the hanger to be flexibly adjusted, allowing the MBR membrane module to precisely adjust the immersion depth according to the actual depth of the membrane tank or changes in the liquid level. This effectively avoids the problems of membrane module exposure, drying and clogging caused by liquid level fluctuations in traditional fixed vibrating membrane devices, and significantly improves the adaptability and operational reliability of the system.

[0005] To achieve the aforementioned objectives, the technical solution of this utility model is: an adjustable vibratory MBR membrane device, comprising a mounting base placed on top of a membrane tank, characterized in that the mounting base is provided with a hanger and a transmission assembly that drives the hanger to reciprocate along the length of the mounting base; a membrane frame is mounted on the hanger, and an MBR membrane module is mounted on the membrane frame; a height adjustment assembly is provided between the hanger and the membrane frame for adjusting the vertical height of the membrane frame relative to the hanger. By adding the height adjustment assembly, the vertical height of the membrane frame relative to the hanger can be adjusted, thereby adapting to membrane tanks of different depths or coping with liquid level fluctuations, effectively preventing the MBR membrane module from being exposed to air, and ensuring treatment efficiency and membrane fiber life.

[0006] Furthermore, the transmission assembly includes a primary drive motor mounted on the mounting base, an eccentric wheel connected to the output end of the primary drive motor, and a connecting rod. One end of the connecting rod is hinged to the eccentric wheel, and the other end is hinged to the hanger. Guide wheels are provided on both sides of the hanger, and guide rails that cooperate with the guide wheels are provided on the mounting base. The primary drive motor drives the eccentric wheel to rotate, and the rotational motion is converted into the linear reciprocating motion of the hanger through the connecting rod. With the guiding structure of the guide wheels and guide rails, the transmission is smooth and reliable, realizing the mechanical vibration anti-fouling function of the MBR membrane module.

[0007] Furthermore, the height adjustment assembly includes a screw mechanism mounted on the hanger and several guide rods for maintaining the stability of the membrane frame during adjustment. By setting up the screw mechanism and several guide rods, the membrane frame can smoothly rise and fall along a predetermined path during height adjustment, avoiding uneven loading or jamming, and ensuring the accuracy of height adjustment and structural stability.

[0008] Furthermore, the lead screw mechanism includes a lead screw and a secondary drive motor for rotating the lead screw. A movable seat is threaded onto the lead screw, and movable seats are slidably connected to each guide rod. The membrane frame is connected to each of the movable seats. The secondary drive motor drives the lead screw to rotate, causing the movable seats and the membrane frame connected to them to move synchronously. The movable seats on each guide rod collectively drive the membrane frame, resulting in uniform force distribution and more stable operation during the adjustment process.

[0009] Furthermore, rails are provided on both sides of the lead screw, and rollers matching the rails are provided on both sides of the movable seat. By setting rails on both sides of the lead screw and configuring matching rollers on the movable seat, the movable seat rolls forward under the drive of the lead screw, reducing sliding friction and improving adjustment efficiency and service life.

[0010] Furthermore, the mounting base is equipped with at least one hanger, and the connected hangers are fixedly connected to each other by rigid connecting rods to form an integral vibration frame. By connecting multiple hangers into an integral vibration frame through rigid connecting rods, the hangers can move synchronously, enhancing the system rigidity and operational stability, and making it suitable for modular expansion applications of large-area membrane tanks.

[0011] Furthermore, the membrane frame, hanger, and mounting base are all made of stainless steel. By using stainless steel to manufacture the membrane frame, hanger, and mounting base, the entire device possesses excellent corrosion resistance, adapting to the long-term erosion of the wastewater treatment environment and extending the service life of the equipment.

[0012] Furthermore, the second drive motor is either a servo motor or a stepper motor. By selecting a servo motor or a stepper motor as the second drive motor, the lead screw mechanism can precisely control the lifting position and speed of the film carriage, achieving a high degree of automation and precise adjustment.

[0013] Furthermore, the mounting base is equipped with a sensor for receiving liquid level signals. By setting up the liquid level sensor, the device can monitor changes in the membrane tank liquid level in real time, providing a signal source for automatic height adjustment and improving the overall intelligence and adaptability of the device.

[0014] Furthermore, the membrane frame and each movable base are connected by a quick-release connection. By using a quick-release connection structure to link the membrane frame and the movable base, the membrane frame can be quickly separated or installed, facilitating maintenance, cleaning, or replacement of membrane components, thereby improving the maintainability and operational efficiency of the equipment.

[0015] The beneficial effects of this utility model are as follows: by adding a height adjustment component between the hanger that is slidably connected to the mounting base and the membrane frame used to install the membrane module, the vertical height of the membrane frame relative to the hanger can be flexibly adjusted, so that the immersion depth of the MBR membrane module can be precisely adjusted according to the actual depth of the membrane tank or changes in liquid level. This effectively avoids the problems of membrane module exposure, drying and clogging caused by liquid level fluctuations in traditional fixed vibrating membrane devices, and significantly improves the adaptability and operational reliability of the system.

The mounting base 1 has a hanger 2 and a transmission assembly 3 that drives the hanger 2 to reciprocate along the length of the mounting base 1. A membrane frame 4 is mounted on the hanger 2, and an MBR membrane module 5 is mounted on the membrane frame 4. A height adjustment assembly 6 is provided between the hanger 2 and the membrane frame 4 to adjust the vertical height of the membrane frame 4 relative to the hanger 2. The transmission assembly 3 includes a primary drive motor 31 mounted on the mounting base 1, an eccentric wheel 32 connected to the output end of the primary drive motor 31, and a connecting rod 33. One end of the connecting rod 33 is hinged to the eccentric wheel 32, and the other end is hinged to the hanger 2. Guide wheels 34 are provided on both sides of the hanger 2, and guide rails 35 that cooperate with the guide wheels 34 are provided on the mounting base 1. The height adjustment assembly 6 includes a screw mechanism 61 mounted on the hanger 2 and several guide rods 62 for maintaining the stability of the membrane frame 4 during adjustment. The lead screw mechanism 61 includes a lead screw 611 and a secondary drive motor 612 that drives the lead screw 611 to rotate. A movable seat 613 is threaded onto the lead screw 611, and each guide rod 62 is slidably connected to a movable seat 613. The membrane frame 4 is connected to each movable seat 613. Tracks 614 are provided on both sides of the lead screw 611, and rollers 615 matching the tracks 614 are provided on both sides of the movable seat 613. At least one hanger 2 is provided on the mounting base 1, and adjacent hangers 2 are rigidly connected to each other by connecting rods 7 to form an integral vibration frame. The membrane frame 4, hangers 2, and mounting base 1 are all made of stainless steel. The secondary drive motor 612 is a servo motor or a stepper motor. A sensor 8 for receiving liquid level signals is provided on the mounting base 1. The membrane frame and each movable seat are connected by a quick-release mechanism.

[0022] The working principle of this utility model is as follows: First, the mounting frame is placed on top of the membrane tank, immersing the MBR membrane module on the frame in the mixed liquor. During operation, the No. 1 drive motor drives the hanger to reciprocate horizontally along the length of the mounting base via an eccentric wheel and linkage mechanism. This causes mechanical vibration in the entire membrane frame and membrane module, generating strong shear force on the membrane fiber surface to effectively remove pollutants and significantly reduce the large amount of aeration required by traditional processes. Simultaneously, the suction pump is connected to the membrane module through a water collection pipe to extract the filtered clean water. During the process, the liquid level sensor on the mounting base monitors the liquid level in the tank in real time. When the liquid level changes, the No. 2 drive motor is activated to drive the screw mechanism, which moves the membrane frame smoothly up and down along the guide rod via the moving seat, automatically adjusting the immersion depth of the membrane module to ensure that it is always in the optimal working position, effectively preventing the membrane module from being exposed or submerged too deeply.

[0023] In summary, the described embodiments are merely some, not all, of the embodiments of this utility model.
