Abstract

The invention discloses an improved type filter device which comprises a fixed frame, a driving component and a filter component installed on the fixed frame. The filter component comprises a spiral stirring part and a filter cartridge. One end of the spiral stirring part is provided with a first gear portion, one end of the filter cartridge is provided with a second gear portion, and the first gear portion and the second gear portion are coaxially arranged and are both driven by the driving component. The two ends of the filter cartridge are open. The spiral stirring part is inserted into the filter cartridge. The filter cartridge is provided with multiple filter holes and sleeved with a filter film and a sleeving shell. The bottom of the sleeving shell is connected with a water outlet pipe. The filter component further comprises a liquid inlet pipe and a bearing pipe, wherein the liquid inlet pipe is inserted to the open end, close to the second gear portion, of the filter cartridge, and the bearing pipe is used for bearing solid particles at the open end, away from the second gear portion, of the filter cartridge. The problems of film face concentration polarization and film pollution can be solved, and the film permeation flux and filter effect are significantly improved.

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...
