Problems solved by technology
[0004] The purpose of the present invention is: to provide a hollow fiber backwashing device, which is used to solve the problem that the ordinary membrane filaments are relatively thin. During backwashing, the membrane filaments are easy to swing and then easily broken, and during long-term use, due to the Due to the erosion of dirty water and the structural problems of the hollow fiber tube itself, the hollow fiber tube is also easy to break, but the two ends of the membrane filament of the ordinary hollow fiber membrane are fixedly connected to the filter body, so when replacing, the whole can only be replaced. The problem of increasing the cost of use

The invention belongs to the technical field of water purification, and specifically relates to a hollow fiber backwashing device, which includes a housing and a cover plate installed on the housing. A filtering mechanism is installed in the housing, and the filtering mechanism includes a mounting frame, a plurality of filter components and a plurality of A backwash pipe, the installation frame is installed in the housing, the outlet pipe is divided into multiple sections, the filter assembly is connected to each section of the outlet pipe, and multiple backwash pipes are evenly installed on the filter assembly. The filter assembly includes a water collection pipe, multiple filter units and The connection block is used to solve the problem that the ordinary membrane filaments are thin, and the membrane filaments are easy to swing and break during backwashing. In addition, during the long-term use of the membrane filaments, due to the erosion of dirty water and the structural problems of the hollow fiber tube , The hollow fiber tube is also easy to break, but both ends of the membrane filament of the ordinary hollow fiber membrane are fixedly connected to the filter body, so that when replacing, only the whole body can be replaced, which increases the cost of use.
Description
technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a hollow fiber backwashing device. Background technique [0002] With the growth of the global population and the acceleration of industrial development, people's demand for water resources is getting higher and higher, and the shortage of resources caused by the unreasonable development and utilization of water resources has seriously affected people's production and life. Today's freshwater resources only account for 0.5% of the total water resources on the earth, and the distribution of resources is unbalanced, resulting in more serious water shortages in some countries and regions. Therefore, how to protect, utilize and distribute water resources reasonably and effectively has become the focus of increasing attention. . [0003] Hollow fiber membranes are used in the separation, concentration and purification of solutions, especially in water treatment...
