Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of the housing.
Fig. 3 is a schematic view of a filter cartridge placement configuration.
The device comprises a shell 1, an upper cover 2, a motor 3, a rotating shaft 4, a filter cylinder 5, a water inlet 6, a water outlet 7, a sewage draining outlet 8, a base 9, a frame 10, a flange 11 and a control cabinet 12.
Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-3, a self-cleaning filter comprises a housing 1, a water inlet 6, a water outlet 7 and a sewage outlet 8, wherein the housing is provided with the water inlet, the water outlet 7 and the sewage outlet 8, the upper end of the housing 1 is provided with an upper cover 2, the upper cover 2 is provided with a motor 3, and the motor 3 is connected with a filtering structure in the housing through a rotating shaft 4; the filter structure comprises a filter cartridge 5 and a base 9, wherein the base 9 is installed at the bottom end of the shell, a frame body 10 is vertically arranged on the base 9, and the filter cartridge 5 is installed on the frame body 10 and drives the filter cartridge to rotate on the base; a control cabinet 12 is arranged on the shell 1.
Preferably, the filter cartridge 5 is made of at least one layer of filter mesh.
Preferably, the rotating shaft 4 is connected with the frame body 10 and drives the frame body to rotate.
Preferably, the sewage draining outlet 8 is communicated with a sewage draining pipeline into the upper cover 2.
Preferably, the water inlet 6 and the water outlet 7 are both provided with a flange 11.
Preferably, the upper cover 2 is fixedly mounted on the housing 1 by means of a plurality of bolts.
Preferably, a differential pressure sensor is arranged between the water outlet 7 and the water inlet 6.
Preferably, a drain valve is arranged on the drain outlet 8.
Preferably, the motor 3, the drain valve and the differential pressure sensor are all connected to the control cabinet 12.
The first embodiment is as follows:
water enters through the water inlet 6 and first passes through the filter cartridge 5 (the coarse screen filters out larger particles of impurities and then to the fine screen). In the filtering process, the fine filter screen gradually accumulates dirt and impurities in water to form a filtering impurity layer, and the filtering impurity layer is accumulated on the inner side of the fine filter screen, so that a pressure difference is formed between the inner side and the outer side of the fine filter screen. When the pressure difference in the shell 1 reaches a preset value, the automatic cleaning process is started, the supply of the purified water is not cut off, the water pressure in the filter cartridge 5 and the shell 1 is greatly reduced, and a suction force is generated between the sewage discharge pipeline and the shell 1 through the pressure difference between the filter cartridge 5 and the shell 1 to form a sewage suction process, namely, the sewage is discharged from the sewage discharge outlet 8. Meanwhile, the rotating shaft 4 of the motor 3 drives the frame body 10 to rotate, the brush moves on the filter cylinder 5, the inner surface of the whole filter screen is completely cleaned, and the whole washing process only needs tens of seconds. The blow-off valve on the blow-off outlet 8 is closed at the end of the cleaning. The filter begins to prepare for the next flush cycle.
Example two:
the control cabinet 12 is connected with a blowdown valve and a differential pressure sensor, and is used for monitoring differential pressure and opening the blowdown valve in time to carry out blowdown, so that the self-cleaning blowdown effect is achieved.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention.
