Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning equipment technology, and in particular to an ultrasonic cleaning device for membrane elements. Background Technology

[0002] Membrane separation technology is widely used in water treatment, food processing, biomedicine, chemical industry and other fields. Membrane elements, as the core filtration components, are susceptible to clogging and fouling by contaminants (such as organic matter, inorganic salts, microorganisms, etc.) during long-term operation, leading to decreased membrane performance, reduced flux, and shortened lifespan. To ensure the operating efficiency and economy of the membrane separation system, regular cleaning of the membrane elements is a necessary maintenance measure.

[0003] Existing membrane element cleaning methods mainly include chemical cleaning and physical cleaning. Among them, ultrasonic cleaning technology is widely used in the auxiliary cleaning process of membrane elements due to its advantages such as non-contact cleaning, uniform cleaning, and high efficiency. Ultrasonic waves transmit high-frequency vibration energy through liquids, which can effectively remove deposits on the membrane surface and within the pores, restoring the flux of the membrane element. However, existing ultrasonic cleaning devices generally have the following problems during use: unreasonable membrane element installation methods, which can easily lead to inaccurate positioning or insecure clamping, causing the membrane element to shake during cleaning and affecting the cleaning effect; and imperfect design of cleaning fluid circulation and discharge, which can easily produce liquid residue inside the equipment, leading to secondary pollution or affecting the next use. Therefore, an ultrasonic cleaning device for membrane elements is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultrasonic cleaning device for membrane elements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultrasonic cleaning device for membrane elements includes a cleaning chamber and a cleaning mechanism. The cleaning mechanism is installed inside the cavity of the cleaning chamber. The cleaning mechanism includes a placement mechanism and an auxiliary mechanism installed inside the cavity of the placement mechanism.

[0007] Preferably, the placement mechanism includes a placement frame and a connecting hole at the bottom edge of the placement frame. Limiting grooves are formed on both sides of the inner wall of the placement frame. Transverse crossbars are horizontally arranged at intervals along the placement frame. Hinges are formed on both sides of the bottom of the other end face of the placement frame. The placement frame is movably connected to a baffle plate via the hinges. The placement frame has a connecting hole that connects to a drain port at the bottom of the placement mechanism, allowing cleaning fluid to drain smoothly. During cleaning, a plug is temporarily used to seal the drain outlet on the outer shell. After cleaning, the drain outlet is opened to drain the fluid, effectively controlling the timing of liquid flow and preventing leakage. The cleaning fluid can... After cleaning, the membrane is discharged in one go, leaving no residue at the bottom of the device or in the cavity, reducing the risk of secondary contamination, facilitating cleaning preparation for the next use, and reducing maintenance costs. The limiting groove allows the plate-shaped membrane element to be inserted laterally and limits its two end faces. The limiting groove acts as a guide groove structure, allowing the plate-shaped membrane element to slide laterally into the clamping assembly, simplifying the loading process and improving operational efficiency. The limiting groove limits and constrains the two end faces of the membrane element, ensuring accurate positioning after insertion and preventing movement due to vibration or water flow during cleaning. The limiting groove provides reliable support for the membrane element, avoiding skewing or contact damage caused by improper manual placement.

[0008] Preferably, the auxiliary mechanism includes a built-in transverse frame and an installation baffle mounted on the side end face of the built-in transverse frame. A storage box is opened on the other end face of the built-in transverse frame, and a cover plate is installed on the top of the storage box. The membrane element to be cleaned is placed into the inner cavity of the storage box, and the auxiliary mechanism is inserted into the cleaning chamber. An external ultrasonic cleaner is started, and the cleaning solution is poured into the cleaning chamber and circulated to perform ultrasonic vibration cleaning on the surface of the membrane element. The membrane element is completely immersed in the cleaning solution. The ultrasonic vibration can act evenly on the membrane surface at 360°, effectively removing contaminants. The matching structure between the top cover and the cleaning chamber ensures that the auxiliary mechanism is inserted and installed firmly, preventing the membrane element from moving during the cleaning process and ensuring cleaning consistency. The transverse crossbar passes through the inner cavity of the built-in transverse frame, so that the placement mechanism and the auxiliary mechanism are combined into a whole.

[0009] Preferably, the cleaning box includes a box body and discharge holes on both sides of the corner of the side end face of the box body, a cleaning chamber is opened in the middle of the box body, a top cover is opened horizontally on the inner wall of the cleaning chamber, and the discharge holes and the connecting holes are interconnected.

The external ultrasonic cleaner is started, and the cleaning solution is poured into the cleaning chamber and circulated to perform ultrasonic vibration cleaning on the surface of the membrane element. The membrane element is completely immersed in the cleaning solution. The ultrasonic vibration can act evenly on the membrane surface in 360°, effectively removing contaminants. The matching structure between the top cover and the cleaning chamber ensures that the auxiliary mechanism is inserted and installed firmly, preventing the membrane element from moving during the cleaning process and ensuring cleaning consistency.

[0012] 2. The placement frame is equipped with a connecting hole, which connects to the drain port at the bottom of the placement mechanism, allowing the cleaning fluid to drain smoothly. During the cleaning process, a plug is used to temporarily seal the drain outlet on the outer shell. After cleaning, the drain outlet is opened to drain the fluid, effectively controlling the timing of liquid flow and avoiding leakage during the process. The cleaning fluid can be discharged all at once after cleaning, without remaining at the bottom of the device or in the cavity, reducing the risk of secondary pollution, facilitating cleaning preparation for the next use, and reducing maintenance costs.

[0013] 3. The limiting groove allows the plate-shaped membrane element to be inserted laterally and limits its two end faces. As a guide groove structure, the limiting groove allows the plate-shaped membrane element to slide laterally into the clamping assembly, simplifying the loading process and improving operating efficiency. The limiting groove limits and constrains the two end faces of the membrane element to ensure accurate positioning after insertion and prevents it from moving due to vibration or water flow during cleaning.

The placement frame 211 has a connecting hole 212, which connects to the drain port 212 at the bottom of the placement mechanism 21, allowing the cleaning fluid to drain smoothly. During the cleaning process, a plug is temporarily used to seal the drain outlet 12 on the outer shell. After cleaning, the drain outlet is opened to drain the fluid, effectively controlling the liquid flow.
