As shown in fig. 15, a fourth stopper 30 is installed on the lower side of the second support ring 46 installed on the filter cartridge 5, as shown in fig. 16, a fourth stopper hole 32 is opened on the upper side of the fixing ring 29, and the fourth stopper 30 is engaged with the fourth stopper hole 32; the filter cartridge 5 is positioned by the cooperation of the fourth limiting block 30 and the fourth limiting hole 32, and the mounting position of the filter cartridge 5 can be fixed according to the positions of the fourth limiting hole 32 and the fourth limiting block 30 when the filter cartridge 5 is mounted.

The specific working process is as follows: when people use the floor drain designed by the utility model, the frame 2 of the floor drain is fixed in the frame hole which is dug by people in advance through cement before use; then the floor drain inner core 3, the filter cylinder 5, the swing plate 7 and the second sealing plate 45 are sequentially installed; the device can be used after being installed; in the using process, firstly, the sewage flowing in through the floor drain cover 1 is filtered through the filter screen 13 arranged on the floor drain cover 1, so that impurities in the sewage are prevented from being brought into a sewer pipe by the sewage to block the sewer pipe, and if some fine impurities flow in through the floor drain cover 1, the flowing-in impurities can be filtered by the swinging plate 7, so that the impurities are prevented from flowing into the sewer pipe; through long-time use, it will increase to be filtered the impurity that remains on swing board 7 by swing board 7, it is dead to block up swing board 7, the sewage of inflow will gather, overflow to the floor drain upside, after people discover, drive wheel 33 rotates, make drive wheel 33 control swing board 7 swing, pour the impurity on swing board 7 into cartridge filter 5 in, swing board 7 can continue to filter the sewage that flows in by the clearance, and the impurity that flows in cartridge filter 5 only occupies the space of a part of cartridge filter 5, cartridge filter 5 can continue to filter sewage, only can be stopped up when the impurity in the cartridge filter has filled up sewage basically, and the cartridge filter is more than the filterable debris of traditional filter screen floor drain, so the number of times of clearance has been reduced.
