Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, and in particular to a vibrating membrane device. Background Technology

[0002] In the wastewater treatment industry, MBR efficiently retains sludge, separating hydraulic retention time and sludge age, greatly extending sludge age, thereby reducing sludge volume at the source.

[0003] However, during use, MBR requires a large amount of air to flush the membrane surface due to membrane fouling, thereby alleviating membrane fouling and resulting in high power consumption. Vibrating the membrane causes it to move in the water, thereby strengthening the flushing of the membrane material in the water and playing a role in alleviating membrane fouling.

[0004] Currently, there are two main types of vibrating membranes: one is the ground-mounted type, where the membrane tank is placed on the ground and the entire tank or membrane module is driven to move. The membrane tank mainly consists of a steel frame, water collection pipes, and membrane modules. Driving the entire membrane tank requires overcoming the weight of the tank and the friction generated by its movement, resulting in higher energy consumption. The other type is the suspended type, where the membrane tank is suspended as a whole and driven to move. This method reduces energy consumption, but because the entire membrane tank needs to be suspended, an additional suspension load-bearing structure is required, and it must be ensured that it does not fall during long-term operation, placing higher demands on the load-bearing capacity of the structure. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a vibrating diaphragm device.

[0006] The invention provides the following technical solution: a vibrating diaphragm device, comprising:

[0007] Membrane framework;

[0008] A membrane module, comprising a plurality of membrane modules disposed on the membrane frame; the membrane module includes an upper conduit, a lower conduit, and membrane material disposed between the upper conduit and the lower conduit;

[0009] Manifold, the manifold disposed on the membrane frame;

[0010] A water collection branch pipe is provided, through which the membrane module is connected to the manifold.

[0011] The feature is that a driving component is used to drive the upper pipe and the lower pipe in the membrane assembly to generate relative displacement, so as to cause the membrane material to deform and shift.

[0012] Furthermore, the driving component includes:

[0013] A driving element, at least one of the driving elements being disposed on the membrane frame;

[0014] The connecting part is provided between the driving member and the membrane assembly. When the driving member is activated, it drives the upper pipe and the lower pipe of each membrane assembly to generate relative displacement through the connecting part.

[0015] Furthermore, the output end of the drive unit is fixedly connected to the connecting part, and the upper pipe of each membrane assembly is fixedly connected to the connecting part.

[0016] Furthermore, the driving component is a driving component whose output end can be translated and extended, and the driving component, when activated, drives the connecting part to move obliquely, vertically, or translatively.

[0017] Furthermore, the driving component is a driving component whose output end can move in multiple directions, and the driving component, when activated, drives the connecting part to move downward in multiple directions.

[0018] Furthermore, the vibrating diaphragm device also includes a support assembly, and the support assembly is disposed on at least one side of the diaphragm assembly;

[0019] The support components include:

[0020] A support rod, one end of which is fixedly connected to the membrane frame;

[0021] An elastic element, wherein the elastic element is disposed between the upper conduit of the membrane assembly and the support rod.

[0022] Furthermore, each membrane frame is provided with a plurality of second limiting components, and the lower pipe of the membrane assembly is limited between adjacent second limiting components on the membrane frame.

[0023] Furthermore, the vibrating diaphragm device also includes an instantaneous vibration structure, wherein the output end of the driving member contacts and engages with the connecting portion, and there is a gap between the two.

[0024] Furthermore, the vibrating diaphragm device also includes a fixing plate, which includes a plate body disposed on the diaphragm frame and a plurality of first limiting components disposed on the plate body, wherein the upper part of each of the support rods is limited between two adjacent first limiting components.

[0025] Furthermore, the support component also includes:

[0026] The guide rail is provided on the support rod; the upper pipe is located inside the guide rail and can move vertically within the guide rail.

[0027] The beneficial effects of this invention are:

[0028] The driving component moves the connecting part up and down, which in turn causes the upper and lower pipes to shift relative to each other. The membrane material is squeezed, causing it to bend and float in the water. Through the counter-current flushing between the membrane material and the water, membrane fouling on the surface of the membrane material can be reduced. Moreover, this device only moves some lightweight components, resulting in lower energy consumption compared to floor-mounted devices. Compared to suspended devices, it does not require a suspension load-bearing structure, thus achieving lower economic costs.

[0029] In this device, the membrane module is tapped by activating the drive unit, and the membrane module is cleaned by vibration, which can significantly reduce and slow down membrane fouling on the surface of the membrane material.

[0030] This device uses vibration to prevent membrane fouling, eliminating the need for an aeration device at the bottom of the membrane module to prevent membrane fouling, thus saving energy and operating costs. Attached Figure Description

Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0042] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0043] Unless otherwise defined, 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 invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] Example 1:

[0045] A vibrating membrane device includes: a membrane frame 1, a membrane module 2, a manifold, a water collection branch pipe 4, and a drive assembly;

[0046] like Figure 1 As shown; multiple membrane modules 2 are arranged side by side inside the membrane frame 1. The number of membrane modules 2 is not limited and can be selected according to the application scenario in actual use.

[0047] The membrane module can be a hollow fiber membrane module or a flat sheet membrane module. In this embodiment, a hollow fiber membrane module is used for illustration.

[0048] Membrane module 2 includes: a lower pipe 21, an upper pipe 23, and membrane material 22;

[0049] The lower pipe 21 is fixedly connected to the inner bottom side of the membrane frame 1. Preferably, the lower pipe 21 is fixedly connected to the inner bottom side of the membrane frame 1 by multiple fixing rings. Of course, in other embodiments, the lower pipe 21 can be fixedly connected to the inner bottom side of the membrane frame 1 by common buckles or bolts.

[0050] The upper pipes 23 of each membrane module 2 are fixedly connected to the bottom of the connecting part 3. The specific fixed connection method of the upper pipes 23 can use the specific fixed connection method of the lower pipes 21 described above.

[0051] One end of the membrane material 22 is fixedly connected to the upper pipe 23, and the other end of the membrane material 22 is also fixedly connected to the lower pipe 21;

[0052] The manifold includes a water collection pipe 5 and a main water collection pipe 8. The water collection pipe 5 is fixedly connected to the inside of the membrane frame 1. The upper part of the water collection pipe 5 is fixedly connected to one end of the main water collection pipe 8. The water collection pipe 5 and the main water collection pipe 8 are connected to each other so that the water in the water collection pipe 5 flows into the main water collection pipe 8. The other end of the main water collection pipe 8 is connected to a product water pump. The product water pump generates pressure so that the water in the water collection pipe 5 and the main water collection pipe 8 can flow.

[0053] To further explain, membrane modules can have either top or bottom water outlets. Top water outlets facilitate maintenance and replacement after the membrane tank is put into use, but they are prone to tangling issues. This can be avoided by adding simple devices such as dividers, thus solving the problem relatively well. Bottom water outlets avoid tangling, but are less convenient for subsequent maintenance and disassembly.

[0054] This embodiment has multiple combinations:

[0055] Combination 1: The upper pipe 23 can be driven by the drive component, the lower pipe 21 is fixedly connected to the membrane frame, the upper pipe 23 discharges water, and the water collection branch pipe 4 is connected to the upper pipe 23 as a flexible hose with deformability; overall optimal, ranked first.

[0056] Combination 2: The upper pipe 23 can be driven by the drive component, and the lower pipe 21 is fixedly connected to the membrane frame. The lower pipe 21 discharges water, and the water collection branch pipe 4 is connected to the lower pipe 21. It is preferably a rigid pipe. However, this method is inconvenient for subsequent operation and maintenance and is slightly inferior to Combination 1. Its overall performance ranks second.

[0057] Combination 3: The lower pipe 21 can be driven by the drive component, the upper pipe 23 is fixedly connected to the membrane frame, the upper pipe 23 discharges water, and the water collection branch pipe 4 is connected to the upper pipe 23. It is preferably a rigid pipe, and its overall performance ranks third.

[0058] Combination 4: The lower pipe 21 can be driven by the drive component, the upper pipe 23 is fixedly connected to the membrane frame, the lower pipe 21 discharges water, and the water collection branch pipe 4 is connected to the lower pipe 23 as a flexible hose with deformability. This method combines all the disadvantages and has the worst overall performance.

[0059] Combination 5: Both the lower pipe 21 and the upper pipe 23 can be driven by the drive component. The upper pipe 23 is connected to the water outlet and collection branch pipe 4, which is a flexible hose with deformability; its overall performance ranks fourth.

[0060] When using the upper pipe 23 for water outlet, such as Figure 4 As shown, the water collection branch pipe 4 connects each membrane module 2 to the water collection pipe 5. Specifically, water collection branch pipes 4 are provided on both sides of the upper pipe 23. One end of the water collection branch pipe 4 is fixedly connected to the upper pipe 23, and the other end of the water collection branch pipe 4 is fixedly connected to the water collection pipe 5, so that the water permeating the membrane module 2 can flow to the water collection pipe 5 through the water collection branch pipe 4. The length of the water collection branch pipe 4 is greater than the movement range of the drive member drive connection part 3, so that the connection part 3 will not pull the water collection branch pipe 4 when it moves.

[0061] When using bottom outlet water, such as Figure 7 As shown, the water collection branch pipe 4 is connected to the lower pipe 23, and the water collection pipe 5 is fixed at the lower end of the membrane frame and connected to the main water collection pipe 8.

[0062] The driving assembly is used to drive the upper pipe 23 and the lower pipe 21 in the membrane assembly 2 to generate relative displacement. The driving assembly includes a driving component and a connecting part 3. In this embodiment, the driving component is a driving component with a translational and telescopic output end, preferably a telescopic rod "hydraulic / pneumatic rod". A fixed rod 7 is fixedly connected to the upper part of the membrane frame 1, and four telescopic rods are fixedly connected to the fixed rod 7. The telescopic ends of the four telescopic rods are respectively fixedly connected to the four sides of the upper part of the connecting part 3. In other embodiments, the number of telescopic rods can be increased or decreased according to the usage scenario, and the installation position of the telescopic rods can be adjusted according to the number. For example, when one telescopic rod is set, the telescopic end of the telescopic rod is fixedly connected to the middle of the top of the connecting part 3. When two telescopic rods are set, the telescopic ends of the two telescopic rods are respectively fixedly connected to the two sides of the top of the connecting part 3, so as to drive... The connecting part 3 experiences uniform force during movement; the telescopic rod can be vertically mounted on the fixed rod 7, with its telescopic end perpendicular to the connecting part 3, thus activating the telescopic rod to drive the connecting part 3 to move up and down. Alternatively, the telescopic rod can be obliquely or horizontally mounted on the fixed rod 7, with its telescopic end inclined or horizontally positioned relative to the connecting part 3. When the telescopic rod is activated, it drives the connecting part 3 to move obliquely or horizontally. The membrane material is initially curved, allowing for subsequent movement and preventing stretching. Furthermore, in other embodiments, the driving component is a multi-directional drive with an output end, preferably a robotic arm. The robotic arm is also existing technology and will not be described in detail here. The movement path of the robotic arm can be S-shaped, spiral, or Z-shaped; the movement speed can be 11cm / s to 20cm / s. Additionally, in other embodiments, such as... Figure 8 and Figure 9As shown, the drive assembly includes a motor 15, a connecting rod 16, and a connecting part. The motor is fixed to the membrane frame by a fixing rod. An L-shaped connecting rod 16 is fixedly connected to the output shaft of the motor. The end of the connecting rod 16 is fixedly connected to the connecting part 3. When the motor 15 is started, the output shaft of the motor 15 rotates, which drives the connecting rod 16 to rotate. Since the connecting rod 16 is L-shaped, it drives the connecting part to perform a circular motion with the horizontal axis of the connecting rod 16 as the radius. By changing the rotation direction of the motor, the connecting part swings back and forth on an arc trajectory drawn with the output shaft of the motor 15 as the center and the horizontal axis of the connecting rod 16 as the radius. The included angle of the arc trajectory is within 120 degrees, thereby causing the membrane material 22 in the membrane assembly to swing and deform, shaking off the accumulated mud between the membrane materials 22.

[0063] Example 1: If the upper pipe 23 needs to be moved, such as in combinations one and two above; the component connection relationship of the drive assembly is as follows:

[0064] The output end of the drive component is fixedly connected to the top of the connecting part 3, and the lower part of the connecting part 3 is fixedly connected to the upper pipe 23.

[0065] Example 2: If the lower pipe 21 needs to be moved, such as in combinations three and four above; the component connection relationship of the drive assembly is as follows:

[0066] The output end of the drive component is fixedly connected to the bottom of the connecting part 3, and the upper part of the connecting part 3 is fixedly connected to the lower pipe 21.

[0067] Example 3: If the upper pipe 23 and the lower pipe 21 need to move towards each other simultaneously, such as in combination 5 above, two sets of drive components can be set up. One set of drive components is used to drive the upper pipe 23 (the connection relationship of the drive components can be referred to in Example 1), and the other set of drive components is used to drive the lower pipe 21 to move (the connection relationship of the drive components can be referred to in Example 2).

[0068] Furthermore, a limiter is provided inside the membrane frame 1. The limiter is located at the longest stretching height of the membrane material 22 and is used to prevent the membrane material 22 from being stretched and damaged.

[0069] In summary, by activating the drive unit, the drive unit moves the connecting part 3 up and down. When the connecting part 3 causes the upper pipe 23 and the lower pipe 21 to move relative to each other, it squeezes the membrane material 22, thereby causing the membrane material 22 to bend and float in the water. Through the counter-current flushing between the membrane material 22 and the water, membrane fouling on the surface of the membrane material 22 can be reduced. At the same time, when the membrane material 22 floats irregularly in the water, the distance between the membrane materials 22 will be closer or farther, thus shaking off the accumulated mud between the membrane materials 22. When the drive unit moves the connecting part 3 upward, the membrane material 22 will return to its original position. This causes the drive unit to move the connecting part 3 up and down repeatedly, which can fully vibrate and clean the membrane material 22.

[0070] Example 2:

[0071] The difference between this embodiment and embodiment one is that: the vibrating membrane device also includes a support component; a membrane component fixing device installed on the membrane frame, wherein the lower pipe 24 of the membrane component 2 is limited between adjacent limiting structures of the membrane component fixing device; an instantaneous vibration structure and a fixing plate 10;

[0072] like Figure 2 and Figure 4 As shown, support components are provided on both sides of membrane module 2, and the support components are used to support the sides of membrane module 2.

[0073] The support assembly includes: support rod 11 and elastic element;

[0074] The lower end of the support rod 11 is fixedly connected to the inner bottom side of the membrane frame 1; the elastic element is a spring 9, the lower end of the spring 9 is fixedly connected to the upper end of the support rod 11, and the upper end of the spring 9 is fixedly connected to the upper pipe 23. The height of the membrane material 22 is consistent with that of the membrane support assembly, so that the membrane material 22 tends to be in a straight state when the membrane assembly is not subjected to external force; the membrane assembly 2 is supported by the support assemblies on both sides, forming a plate shape. In this embodiment, the driving component is a vertically installed telescopic rod. The extension and retraction of the telescopic rod drives the connecting part 3 to move up and down. The connecting part 3 compresses the spring 9 downward, and the membrane material 22 bends. The connecting part 3 springs the spring 9 back to its original position, and the membrane material 22 is straightened. The membrane material 22 shakes off the sludge and other pollutants attached to it, preventing membrane fouling. In this embodiment, the ratio of the length of the spring 9 to the length of the support rod 11 is 1:1 to 1:10.

[0075] The membrane module fixing device is provided on the membrane frame 1. The number of limiting structures of the membrane module fixing device is adapted to the number of membrane modules 2. The membrane module fixing device is the device in the patent publication number: CN112108004B. Since the membrane module fixing device is prior art, it will not be described in detail here. The second limiting component 12 corresponds to the limiting structure of the membrane module fixing device.

[0076] The upper pipe 23 is fixed to the connecting part 3; the lower pipe 21 is located in the slot formed between adjacent second limiting parts 12 on the membrane frame 1; thereby, the lower pipe 21 of the membrane assembly 2 is detachably connected to the membrane frame 1 through this snap-fit ​​method.

[0077] In this embodiment, the instantaneous vibration structure includes: the output end of the drive member and the connecting part 3 are not fixedly connected, but are in contact with each other, and there is a gap between the output end of the drive member and the connecting part 3; by setting the instantaneous vibration structure, instantaneous vibration is formed when the output end of the drive member contacts the connecting part 3 downwards. Since the upper pipe 23 of the membrane module is fixedly connected to the connecting part 3, the vibration is transmitted to the upper pipe and the membrane material fixedly connected to the upper pipe, which helps the sludge and other pollutants on the membrane module 2 to fall off.

[0078] like Figure 3 As shown, a fixing plate 10 is fixedly connected to both sides of the membrane frame 1. The two fixing plates 10 limit the support rods 11 on both sides respectively. The fixing plate 10 includes: plate body 101 and first limiting component 102.

[0079] The plate 101 is fixedly connected to the membrane frame 1. Several first limiting components 102 are fixedly connected to the side of the plate 101 near the support rod 11. The number of first limiting components 102 is adapted to the number of support rods 11 so that the upper part of each support rod 11 is limited between two adjacent first limiting components 102. The specific structure of the first limiting component 102 can be referred to the specific structure of the second limiting component 12, which will not be described in detail here. When the spring 9 is compressed, the upper part of the support rod 11 is prevented from shaking because the fixed plate 10 limits the upper part of the support rod 11.

[0080] In this embodiment, since the connecting part 3 only moves up and down and has a single movement path, the connection between the membrane assembly 2 and the connecting part 3 is subjected to longitudinal tension. The membrane material 22 itself has a certain elasticity, and its buffering capacity is stronger in the longitudinal direction and weaker in the lateral direction, thereby avoiding damage and breakage of the membrane material 22.

[0081] Furthermore, during the operation of the vibrating membrane device, the operating frequency of the drive component is 0.5s / time to 120s / time, which is the frequency at which the drive component strikes the membrane module 2; while the operating frequency of the drive component in the water production stage is 10s / time, and the operating frequency of the drive component in the backwashing membrane box stage is 2s / time.

[0082] In addition, the drive unit can be connected to an intelligent control system, and the tapping frequency and amplitude can be adjusted according to the actual conditions such as the sludge concentration, water production, and membrane module fouling around the vibrating membrane device.

[0083] Example 3:

[0084] like Figure 5 and Figure 6 As shown, the difference between this embodiment and embodiment two is that the support component further includes a guide rail 13; and the fixing plate 10 is not provided in this embodiment.

[0085] The top end of the support rod 11 is fixedly connected to the guide rail 13, and the guide rail 13 has a vertical guide hole 14 in the middle. The side of the upper pipe 23 is located in the guide hole 14 so that the upper pipe 23 can move up and down in the guide hole 14. The spring 9 is also located in the guide hole 14. The top surface of the support rod 11 is larger than the cross-section of the spring 9, providing a base support for the spring 9.

[0086] In this embodiment, the guide rail 13 provides support for the upper pipe 23 when it moves up and down, preventing it from tilting and protecting the spring 9, thereby making the device operate more stably.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
