Silicon carbide ceramic membrane filtering device

Abstract

The invention discloses a silicon carbide ceramic membrane filtering device, and belongs to the technical field of filtering equipment, wherein the silicon carbide ceramic membrane filtering device comprises a workbench, a filtering box, a first water pressure sensor, a second water pressure sensor, a silicon carbide ceramic membrane, impurity removal equipment and backflow equipment. When the device works, dead-end filtering is firstly carried out, if the pressure borne by the first water pressure sensor is far larger than that borne by the second water pressure sensor, it is indicated that impurities block the silicon carbide ceramic membrane after long-time filtering, and at the moment, the first water pressure sensor and the second water pressure sensor transmit signals to carry out cross-flow filtering; impurities in the silicon carbide ceramic membrane can be taken out through cross-flow filtration, then waste water carries the impurities to enter the impurity removal equipment, then the impurities are recycled by the impurity removal equipment, the remaining liquid returns to the filtering box again through the backflow equipment, and cleaning of the silicon carbide ceramic membrane is completed; and after cleaning of the silicon carbide ceramic membrane is completed, the whole device can continue to return to a dead-end filtering state, so that the filtering efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of filtering equipment, in particular to a silicon carbide ceramic membrane filtering device. Background technique

[0002] During sewage treatment, filtration is almost a necessary process. Filtration is carried out through the filter screen. Since the impurities larger than the filter holes are intercepted by the filter screen, a large amount of impurities will adhere to the filter screen after working for a period of time, and these impurities will be reduced. It is necessary to remove the impurities on the filter regularly to prolong its service life.

[0003] The Chinese invention patent with the publication number CN112057942A in the prior art discloses a cross-flow ceramic membrane filter in the field of petrochemical industry, which includes a feed box, a filter box, an impurity removal box, a feed box, a filter The box body and the impurity removal box are both rectangular parallelepiped. The filte...
