Description

Technical Field

[0001] This utility model relates to the field of vibrating membrane technology, specifically to a filter fixing structure for a vibrating membrane. Background Technology

[0002] The stable operation of a vibrating membrane filtration system is highly dependent on the filtration fixation structure of the vibrating membrane. This structure not only needs to reliably support and position the membrane module, but also ensure that the membrane maintains structural stability during long-term high-frequency vibration, avoiding a decrease in filtration accuracy or damage to the membrane module due to displacement or deformation. For example, CN206108989U discloses a membrane assembly for a vibrating membrane separation device, which relates to the field of filtration membrane device technology. The membrane assembly includes a base made of stainless steel, a guide plate, a filter membrane, a sealing ring, and a water purification pipe. The sealing ring seals the edge of the filter membrane to the base. The screw holes on the sealing ring correspond one-to-one with the screw holes on the base. The sealing ring and the base are fixed by screws. The water purification pipe is made of rubber. The inner wall of the water purification pipe is provided with teeth spaced along the circumference of the pipe wall. The inner wall of the water purification pipe is also provided with a positioning shaft. The positioning shaft abuts against the teeth. The tooth structure can create a gap between the water purification pipe and the positioning shaft as a liquid flow channel. The positioning shaft can fix the water purification pipe and prevent relative displacement between the water purification pipe and the membrane assembly when the membrane assembly vibrates in the horizontal direction, thus ensuring the water output effect and protecting the filter membrane. However, in the existing technology, the membrane module is pressed and fixed to the equipment frame by rigid connectors such as bolts and clamps for multi-layer modules. Under high-frequency vibration conditions, the rigid connection is prone to stress concentration, which may not only cause damage to the edge of the membrane, but also cause resonance of the equipment frame due to uneven vibration transmission, increasing noise and energy consumption. At the same time, the device is difficult to replace and repair when a single module is damaged due to the overall fixation, resulting in low efficiency. Therefore, it is urgent to design a filter fixing structure for vibrating membranes to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a filter fixing structure for a vibrating membrane, in order to solve the problems mentioned in the background art. The membrane module is pressed and fixed to the equipment frame by rigid connectors such as bolts and clamps. Under high-frequency vibration conditions, the rigid connection is prone to stress concentration, which may not only cause damage to the edge of the membrane, but also cause resonance of the equipment frame due to uneven vibration transmission, increasing noise and energy consumption. At the same time, the device is difficult to replace and repair when a single module is damaged due to overall fixing, resulting in low efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter fixing structure for a vibrating diaphragm, comprising a fixing member, a connecting member, and a module body. The fixing member can enclose and clamp the module body inside. The fixing member and the module body have the same specifications.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 One embodiment provided by this utility model: A filter fixing structure for a vibrating diaphragm includes a fixing member 1, a connecting member 2, and a mold body 3. The fixing member 1 can wrap and clamp the mold body 3. The fixing member 1 and the mold body 3 have the same specifications. The connecting member 2 is adapted and assembled according to the number of layers of multiple sets of fixing members 1.

[0017] As a further feature of this invention, the fixing member 1 includes an upper clamping ring 11 and a lower clamping ring 12. The upper clamping ring 11 and the lower clamping ring 12 are made of the same material and are mirror-connected. The interior of the upper clamping ring 11 and the lower clamping ring 12 has a semi-arc design. The semi-arc design of the upper clamping ring 11 and the lower clamping ring 12 provides stable positioning for the main body 3 of the template with different thicknesses. The above design is beneficial for positioning the main body of the template, thereby improving the protective effect.

[0018] Furthermore, both ends of the upper clamping ring 11 are provided with arc-shaped slots 112, and two sets of mating holes 111 are provided on the front and rear sides of the upper clamping ring 11. The upper clamping ring 11 and the lower clamping ring 12 are fixed together by bolts through the mating holes 111. The above design is beneficial to the connection stability, and the sealing performance is improved by the sealing rings provided on the upper and lower parts of the fastener.

[0019] As a further improvement of this utility model, the connector 2 includes an adapter retaining ring 21 and a connecting block 22. The adapter retaining ring 21 adopts a C-shaped design and is made of the same material as the fixing member 1. The connecting block 22 is fixed at the rear end of the adapter retaining ring 21. The adapter retaining ring 21 includes an upper arc clamping plate 211, a lower arc clamping plate 213, and a connecting plate 212. The inner wall of the connecting plate 212 is correspondingly fixed with the upper arc clamping plate 211 and the lower arc clamping plate 213. The upper arc clamping plate 211 and the lower arc clamping plate 213 can be pushed into the arc-shaped slot 112 for locking. The adapter retaining ring 21 can limit and clamp the fixing member 1 with multiple layers. The connecting block 22 can be installed in the filtration equipment. The above design is beneficial for connecting fixing members and module bodies with different layers, thereby improving installation efficiency.

[0020] Working principle: In use, the user first places a set of module bodies 3 on the top of the lower clamping ring 12, and then covers the lower side of the upper clamping ring 11 on the module body 3, while keeping the lower clamping ring 12 and the upper clamping ring 11 aligned. Then, bolts are used to make a hidden connection through the mating hole 111. After a set of module bodies 3 is installed in the fixing part 1, the upper arc clamping plate 211 and the lower arc clamping plate 213 can be locked in the arc-shaped groove 112 by sliding the C-shaped adapter rings 21 on both sides. Finally, the connecting block 22 is installed on the filtration equipment. The above is the complete working principle of this utility model.
