Filtering apparatus

Abstract

Disclosed is a filtering apparatus capable of minimizing the relative vibration of the filtering membrane module within the frame structure during the aeration cleaning process, thereby preventing the damage of the filtering membrane module which might be caused due to the relative vibration as well as the separation of the filtering membrane module from the frame structure. The filtering apparatus comprises a frame structure including a cross bar and a filtering membrane module installed in the frame structure. The cross bar comprises a first rib inserted into a receiver of the header of the filtering membrane module. The filtering apparatus further comprises a stopper fastened to an end of the first rib passing through a through-hole of the receiver so as to prevent the filtering membrane module from being separated from the frame structure.

Description

technical field [0001] The present invention relates to a filter device, which includes a frame structure and a filter membrane module installed therein, in particular to a filter that can minimize the relative vibration of the filter membrane module in the frame structure during the aeration cleaning process device, thereby preventing the filter membrane module from being damaged due to relative vibration and preventing the filter membrane module from being separated from the frame structure. Background technique [0002] Separation methods for water treatment include methods using membrane filtration, methods using heating or phase change, and the like. [0003] Separation methods using membrane filters have many advantages over methods using heat or phase transitions. One of the advantages is the high reliability of water treatment, because water of desired purity can be obtained easily and stably by adjusting the size of filter membrane pores. Furthermore, since the se...

Problems solved by technology

[0010] As a result, the filter membrane module was damaged when it collided with the frame structure, which caused serious problems: as the replacement cycle of the filter membrane module was shortened and the replacement cost increased

[0016] However, according to the above structure, the connecting wings of the pair of connecting rings inserted into the header must be elastic, and therefore, the relative vibration of the hollow fiber membrane modules within the frame structure cannot be completely prevented

Also, since the connection state of the frame structure and the hollow fiber membrane module depends only on small protrusions, there is a high risk that the protrusions are damaged due to the relative vibration of the hollow fiber membrane module, thereby causing the hollow fiber membrane module to be separated from the frame structure
