Description

Technical Field

[0001] The present invention relates to the field of ceramic nanofiltration membranes, in particular to a nanofiltration membrane water treatment device for a ceramic nanofiltration membrane cleaning mechanism. Background Art

[0002] Ceramic nanofiltration membrane is a membrane material used in water treatment and separation technology. It has good high temperature resistance, acid and alkali resistance and pollution resistance. It is mainly made of ceramic materials (such as alumina, zirconia, etc.) and is widely used in drinking water treatment, wastewater treatment, food industry and separation in chemical processes. During the production and processing of ceramic nanofiltration membranes, some impurities and debris will adhere to the surface and interior of the ceramic nanofiltration membrane. In order to ensure the normal use of the ceramic nanofiltration membrane, a ceramic nanofiltration membrane cleaning mechanism is required to clean the ceramic nanofiltration membrane. When the existing ceramic nanofiltration membrane cleaning mechanism cleans the ceramic nanofiltration membrane, the impurities and debris cleaned by the ceramic nanofiltration membrane will fall on the filter screen in the cleaning pool. The cleaning water can be filtered and purified through the filter screen, and then the cleaning water can be recycled, saving water resources. After the cleaning work of the cleaning mechanism is completed, the filter screen needs to be cleaned. The impurities on the surface are cleaned, and during the cleaning process, water is extracted from the cleaning pool by using a water pump and sprayed out through the nozzle to rinse the ceramic nanofiltration membrane. At the same time, a motor is used to drive the brush to move so that the brush can scrub the surface of the ceramic nanofiltration membrane, which can completely clean the ceramic nanofiltration membrane and prevent impurities from adhering to the ceramic nanofiltration membrane. In order to prevent the filter from being blocked by impurities and debris during the cleaning process, thereby affecting the filtering effect, a driving mechanism is also required to drive the push plate to move to prevent the filter from being blocked. During use, the entire cleaning mechanism requires the use of multiple sets of driving mechanisms, which consume a lot of power for daily cleaning and have a high cleaning cost. Secondly, when performing daily maintenance on the cleaning structure and equipment, multiple sets of driving mechanisms are required for maintenance and repair, which is time-consuming and labor-intensive.
