[0009] Furthermore, the inner sides of the two groups of positioning frames are provided with card slots that are compatible with the sizes of both sides of the filter plate. The positioning frame structure can be quickly fixed to the filter plate through the card slot structure. For users, filter plate structures of different mesh sizes can be determined according to different usage positions and functions, and the fixed card function can be realized, which is convenient for users to quickly plug and fix, and can prevent the filter plate from falling when it is flipped; when the left port at the top is used as the liquid inlet, the filtered liquid flows out from the right port at the bottom, and the debris is left at the top of the filter plate, and there will be no debris at the bottom of the filter plate, so when the filter cartridge is flipped, the debris placed on the top of the filter plate can be poured out through the port on one side, and the debris will be left at the top after the flip, which effectively solves the problem that the filtering device in the prior art is easy to accumulate dirt, the filter screen needs to be cleaned frequently, and manpower and material resources are wasted.

[0010] Furthermore, a curved pipe structure bent outward is fixedly inserted into each group of the left port and the right port, and the curved pipe structure can raise the height at which liquid enters. The utility model drives the filter cartridge to rotate by one end of a driving motor, and cooperates with the internal left port and right port to perform functional conversion. The active rotation function of the driving motor can drive it to rotate automatically, and perform functional conversion according to user needs, which saves time and effort and can also meet the user's needs for quick operation.

[0011] Furthermore, the two groups of structures in the left port and the right port are symmetrical according to the central axis of the filter cartridge, and two groups of pipeline structures are provided in the left port and the right port, so that the user can select the liquid inlet and outlet before and after flipping to meet the use requirements.

[0012] Furthermore, the two groups of positioning frames are symmetrically arranged at both ends of the filter cartridge. The two symmetrically arranged positioning frame structures can improve the stability of the filter plate when it is flipped, and divide the internal space of the filter cartridge into two, which is convenient for functional zoning.

[0013] Furthermore, the inner wall of the filter cartridge is coated with a corrosion-resistant coating to extend the service life of the filter cartridge and improve the corrosion resistance effect.

[0016] In this device, the utility model drives the filter cartridge to rotate by means of one end of the driving motor, and cooperates with the left port and the right port inside to perform function conversion. The active rotation function of the driving motor can drive it to rotate automatically, and the function conversion can be performed according to the needs of the user, which saves time and effort and can also meet the needs of the user for quick operation.

[0017] In the device, both sides of the filter plate in the filter cartridge can realize the conversion of functional partitions as the filter cartridge rotates. When the left port at the top is used as the liquid inlet, the filtered liquid flows out from the right port at the bottom, and the debris is left at the top of the filter plate. There will be no debris at the bottom of the filter plate, so when the filter cartridge is flipped, the debris placed on the top of the filter plate can be poured out through the port on one side, and the debris will be left at the top after the flipping. It effectively solves the problem that the filtering device of the prior art is easy to accumulate dirt, the filter screen needs to be cleaned frequently, and manpower and material resources are wasted. The filtering device of the utility model has a simple structure, can automatically backwash and clean the filter screen, and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
