An Improved Rotating Membrane Sewage Filtration Device

Abstract

The invention discloses an improved rotating membrane sewage filtration device, which comprises a rack, a filter box, a first rotating shaft, a motor and a filter cartridge. A plurality of filter holes are formed on the circumferential wall of the filter cartridge, the outer circumferential wall of the filter cartridge is fixedly sleeved with a membrane member, the left side wall of the filter cartridge is connected to a liquid inlet tank, the bottom side wall of the filter box is provided with a liquid outlet, the right end side wall of the filter cartridge is provided with a slag outlet, a second rotating shaft in transmission connection with the first rotating shaft is mounted on the filter box, the second rotating shaft is equipped with a gear able to rotate synchronously therewith, and engaging teeth engaged with the gear are formed on the right side of the filter cartridge. The right end of the slag outlet is connected to a convergent cylinder, a rubber sleeve is inserted in the convergent cylinder, the right end of the rubber sleeve is connected to a plurality of petals, and each petal is equipped with an adjustment unit. The improved rotating membrane sewage filtration device provided by the invention well solves the concentration polarization and membrane pollution problems of the membrane surface, significantly increases the membrane permeation flux, and greatly improves the membrane separation performance.

Description

Technical field [0001] The invention belongs to the technical field of membrane treatment, and specifically relates to an improved rotary membrane sewage filtering device. Background technique [0002] Membrane separation technology has become a marginal science that integrates macromolecules, chemical engineering, biology, physics and mathematics, and will have an immeasurable impact on changing the energy structure of the industry, environmental protection and the development of new technologies. Because membrane filtration has the advantages of high separation efficiency, low energy consumption and simple operation, it is widely used in the field of solid-liquid separation. Especially as people's awareness of environmental protection has gradually strengthened, membrane separation technology has been placed high expectations and is considered to be one of the most promising new technologies in the 21st century. [0003] At present, traditional membrane separation generally uses...
