Rotary membrane sewage filtration device

Abstract

The invention discloses a rotary membrane sewage filtration device, which comprises a frame, a filter box, a first rotating shaft, a motor, and a filter cartridge. The filter box is installed on the frame, the first rotating shaft is rotatably installed in the filter box, the motor is used for driving the first rotating shaft to work, the filter cartridge is rotatably sheathed on the first rotating shaft, a plurality of filter holes are formed on the circumferential wall of the filter cartridge, a membrane member is fixedly sleeved on the external circumferential wall of the filter cartridge, the left end side wall of the filter cartridge is connected to a liquid inlet box, 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 hole, a second rotating shaft in transmission connection with the first rotating shaft is mounted on the filter box and is equipped with a gear able to rotate synchronously with it, and meshing teeth engaged with the gear is formed on the right side of the filter cartridge. The rotary membrane sewage filtration device provided by the invention well solves the membrane surface concentration polarization and membrane pollution problems, significantly increases the membrane permeation flux, and greatly improves the separation performance of the membrane.

Description

technical field [0001] The invention belongs to the technical field of membrane treatment, and in particular relates to a rotating membrane sewage filter device. Background technique [0002] Membrane separation technology has become a marginal science integrating polymer, chemical engineering, biology, physics and mathematics, which will have an immeasurable impact on changing the energy structure of the industry, environmental protection and the development of new technologies. Due to the advantages of high separation efficiency, low energy consumption and simple operation, membrane filtration is widely used in the field of solid-liquid separation. Especially as people's awareness of environmental protection gradually strengthens, membrane separation technology is placed with high expectations and is considered to be one of the most promising new technologies in the 21st century. [0003] At present, the traditional membrane separation generally adopts a static filtrati...
