Description

Technical Field

[0001] This utility model relates to the technical field of membrane permeation devices, specifically a high-efficiency membrane permeation device for MBR membranes. Background Technology

[0002] MBR membrane is a new type of wastewater treatment system that organically combines membrane separation technology with biological treatment technology. MBR membrane combines conventional biological treatment (such as activated sludge) processes with membrane filtration to provide a high level of removal of organic matter and suspended solids. MBR membrane can efficiently perform solid-liquid separation, with a separation effect far better than traditional sedimentation tanks. The effluent quality is good, with suspended solids and turbidity close to zero. Since a portion of the leachate feed solution is used as a carbon source to bypass into the biological treatment tank, impurities, fibrous materials, and high concentrations of biological sludge in the feed solution can clog the MBR membrane pores, requiring the use of a membrane flushing device.

[0003] Common MBR membrane high-efficiency membrane cleaning devices typically use plastic hoses to circulate water for cleaning. However, the water pressure is low, and the membrane tubes have many pores, making the process time-consuming and labor-intensive. This is not conducive to cleaning and makes it difficult to completely remove contaminants from the membrane pores, especially highly adhesive substances such as bacterial exopolymers and microbial metabolites. Frequent cleaning and maintenance are required, increasing labor and material costs and negatively impacting the user experience. Therefore, we propose a new MBR membrane high-efficiency membrane cleaning device. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides a high-efficiency membrane cleaning device for MBR membranes, offering advantages such as improved cleaning efficiency and reduced manual intervention. Through a telescopic control mechanism, a second telescopic connecting frame is fitted onto the outer wall of a telescopic adjusting rod via an inner adjusting groove. A control motor drives the telescopic adjusting rod to rotate, and the telescopic adjusting rod rotates inside the first telescopic connecting frame via an inner rotary bearing, allowing the second telescopic connecting frame to extend and retract on the outer wall of the telescopic adjusting rod. An anti-slip plate at one end of the second telescopic connecting frame serves as a limit to prevent slippage. A positioning cover plate positions the high-pressure flushing gun inside. A high-pressure flushing pump transmits flushing water to the high-pressure flushing gun via a transmission water pipe for automatic flushing. After flushing one membrane pore, the device can be telescopically adjusted to flush the next, providing higher water pressure and more effectively removing contaminants and deposits from the membrane surface. Compared to manually using a plastic hose to flush water, the cleaning speed is faster and the effect is better, effectively solving the problems in the background technology.
