Description

Technical Field

[0001] This utility model relates to a filtration system maintenance device, specifically a pneumatic membrane stripping device for efficiently removing deposits from the surface of the filter medium. Background Technology

[0002] During the operation of a filtration system, as the filtration time increases, a dense filter cake layer or membrane fouling gradually forms on the surface of the filter media, which can lead to the following problems:

[0003] The filtration efficiency drops significantly, by more than 50%.

[0004] The system's energy consumption has increased dramatically;

[0005] The lifespan of the filter element is shortened.

[0006] Traditional cleaning methods have obvious limitations:

[0007] Backwashing technology: has limited effectiveness against deep blockages and is difficult to completely remove deposits;

[0008] Chemical cleaning: may cause secondary pollution, and long-term use may damage the filter media;

[0009] Mechanical scraping: can easily damage the structure of the precision filter membrane and affect the filtration effect.

[0010] Therefore, the development of a high-efficiency, non-contact, and low-damage filter media cleaning device has become an urgent need in the industry. Utility Model Content

[0011] This invention provides a pneumatic membrane removal device, which aims to achieve efficient removal of pollutants from the surface of the filter medium through mechanical vibration generated by high-frequency pulsed airflow, thereby improving the maintenance efficiency of the filtration system, extending the service life of the filter element, and reducing system energy consumption.

[0012] To achieve the above objectives, this utility model employs the following technical solution:

[0013] A pneumatic demolding device includes a stainless steel upper sealing cover and a lower sealing cover, and a rubber inflation / deflation bladder is disposed between the upper and lower sealing covers to generate high-frequency mechanical vibration by inflation / deflation.

[0014] The bottom of the lower sealing cover is connected to a mounting flange, and an HDPE hammer bushing is provided in the center of the mounting flange. A DN15 inlet and outlet port is provided on one side of the mounting flange for connecting to the pneumatic control system and controlling the inflation and deflation of the bladder.

[0015] A lifting rod is provided through the center of the upper sealing cover. Its top end is fixed to the upper sealing cover by a hexagonal nut, and its lower part extends into the hammer bushing. It is used to move up and down to generate vibration during the inflation and deflation of the bladder.

[0016] The upper and lower ports of the hammer bushing are respectively provided with retaining rings and sealing inner bushings to fix the lifting rod and prevent gas leakage;

[0017] O-rings are provided near the inner walls of the upper and lower ends of the hammer bushing, and near the top of the lifting rod and at the inner and outer walls of the hammer bushing, to enhance the sealing of the device.

[0018] Furthermore, the mounting flange is used to secure the entire pneumatic membrane removal device to the filtration system, ensuring the stability of the device during operation.

[0019] Furthermore, the DN15 inlet and outlet ports are connected to a pneumatic control system, which adjusts the vibration frequency and amplitude of the lifting rod by controlling the inflation and deflation speed and cycle of the bladder.

[0020] Furthermore, the pneumatic membrane stripping device is integrated into the filtration system, and the periodic membrane stripping of the filter media is achieved through automated control, thereby improving the maintenance efficiency and filtration effect of the filtration system.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] Non-contact cleaning: avoids damage to the filter membrane caused by traditional mechanical scraping, and protects the integrity of the filter media.

[0023] High efficiency: High-frequency mechanical vibration can thoroughly remove deposits from the surface of the filter media, improving cleaning efficiency.

[0024] Low energy consumption: Compared with traditional cleaning methods, this device does not require a large amount of water or chemical agents, thus reducing operating costs.

[0025] Extend filter life: Regularly using this device for membrane removal can significantly extend the service life of the filter element.

[0026] High degree of automation: The device can be integrated into the filtration system to achieve automated control and reduce manual intervention. Attached Figure Description

[0043] Working principle

[0044] This device uses a sophisticated pneumatic control system to control the inflation and deflation process of the rubber inflation and deflation bladder. When the bladder is inflated, it pushes the lifting rod upward; when the bladder is deflated, the lifting rod moves downward under the influence of gravity. Through the periodic inflation and deflation process, the lifting rod generates high-frequency mechanical vibration. This vibration is transmitted to the surface of the filter media through hammering the bushing, achieving non-contact cleaning and effectively removing adhering media.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
