Abstract

The invention discloses an improved filter device, which comprises a fixed frame, a transmission part, and a filter part installed on the fixed frame. The filter part includes a spiral stirring piece and a filter cylinder. One end of the cylinder is provided with a second gear part, the first gear part and the second gear part are arranged coaxially, both the first gear part and the second gear part are driven by transmission parts, the filter cylinder is open at both ends, and the spiral stirring element Inserted in the filter cartridge, the filter cartridge is provided with a plurality of filter holes, the filter cartridge is set with a filter membrane, the filter cartridge is covered with a casing, the bottom of the casing is connected to the water outlet pipe, and the filter part also includes a filter from the filter cartridge A liquid inlet pipe inserted near the open end of the second gear part, and a receiving pipe for receiving solid particles from the filter cartridge at the open end far away from the second gear part. The invention can effectively solve the problems of concentration polarization and membrane fouling on the membrane surface, and significantly improve the permeation flux and filtration effect of the membrane.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an improved filter device. Background technique [0002] Membrane filtration 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. [0003] At present, membrane filtration technology has been widely used in sewage treatment. However, the existing membrane filtration devices generally adopt a static filtration method, which has the following disadvantages: after a period of filtration, colloidal particles and solute macromolecules are adsorbed on the membrane surface or in the membrane pores, and concentration differences on the membrane surface are prone to occur. Polarization and membrane fouling phenomena reduce the membran...
