Detailed Description
The utility model is described in further detail below with reference to the attached drawings and detailed description:
as shown in fig. 1 and 2, a reverse osmosis large-flux cartridge filter comprises a filter shell 1 and a detachable cover body 2 arranged at the top of the filter shell, wherein a liquid inlet 3 and a liquid outlet 4 are respectively arranged at the side part and the lower part of the filter shell 1, a mounting plate 5 is arranged at the upper end inside the filter shell 1, a plurality of mounting holes 6 are formed in the mounting plate 5, a bag-type filter element 11 is arranged in each mounting hole 6, the bag-type filter element 11 is a flexible polypropylene fiber bag-type filter element, and the upper edge of the bag-type filter element 11 is fixed on the mounting hole 6 through a compression assembly.
As shown in fig. 2, the compressing assembly comprises a compressing ring 8 for compressing the upper edge of the fixed bag-type filter element 11, the compressing ring 8 is used for compressing the fixed bag-type filter element 11 to prevent the fixed bag-type filter element from falling off, a sealing ring 81 placed in the annular groove 7 is arranged at the bottom of the compressing ring 8, the sealing ring 81 ensures the tightness of the compressing ring 8, liquid on the upper part of the mounting plate 5 is prevented from seeping to the lower part, the top of the liquid compressing ring 8 is fixed through a fixing strip 9, and the fixing strip 9 is used for fixing the compressing ring 8.
