Description

Technical Field

[0001] The utility model relates to the technical field of self-cleaning filters, in particular to a self-cleaning filter. Background Art

[0002] The self-cleaning filter is a precision device that uses a filter to directly intercept impurities in the water, remove suspended solids and particulate matter in the water, reduce turbidity, reduce system dirt, algae, rust, etc., to purify water quality and protect the normal operation of other equipment in the system. Water enters the self-cleaning filter body from the water inlet. The self-cleaning filter is a widely used device in the water treatment industry. Its simple design and good performance enable the sewage to achieve the best filtering effect;

[0003] According to Chinese patent CN 219050548 U, a self-cleaning filter is disclosed, which relates to the technical field of filtering equipment. The utility model includes an outer shell, a screw barrel, a closed disk and a control shell. The lower external thread of the outer shell is threadedly connected with a screw barrel, a transfer shell is fixed in the lower part of the screw barrel, a closed disk is fixed at the top of the outer shell, a driving motor is fixed at the top center of the closed disk, a control shell is fixed through the closed disk on one side of the driving motor, and a piston is movably connected in the control shell. The utility model solves the problem that the self-cleaning filter uses a large number of electronic control devices with poor reliability, and the water flow is easy to break during cleaning and only rinses one position, causing deformation of the filter element and poor flushing effect by arranging the outer shell, the screw barrel, the closed disk and the control shell. The advantages of the utility model are: reducing the participation of electronic equipment in controlling cleaning, better reliability, and the filter element can be cleaned more comprehensively during cleaning;

[0004] Although this patent can achieve the effect of stirring water by rotating the fan frame, since the fan frame stirs in one direction, this may cause impurities and particulate matter to accumulate on one side or in a certain area of ​​the fan frame's rotation direction. This local accumulation will reduce the filtration efficiency because the impurities may clog the filter or pores and reduce the flow area. In addition, stirring in a single direction may not be able to evenly clean the entire filter. Some areas may be fully cleaned, while other areas may still accumulate impurities, resulting in inconsistent filtration effects.

[0005] Therefore, it is necessary to provide a new self-cleaning filter to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a self-cleaning filter.

[0007] The utility model provides a self-cleaning filter, comprising a body, wherein a filtering mechanism for filtering water is installed inside the body, and the filtering mechanism comprises:

[0008] A filter assembly is installed on the inner side of the body, and includes a filter cartridge fixed on the inner side of the body, and a stirring assembly for accelerating the water filtering speed is installed on the outer side wall of the filter cartridge;

[0009] The driving assembly is installed on the top of the main body and is used to drive the stirring assembly to stir.

[0010] Preferably, the stirring assembly includes three stirring rods equidistantly arranged on the inner side of the body, three stirring blades are equidistantly fixed on the outer wall of each stirring rod, and the top of each stirring rod is fixed to the output end of the driving assembly.

[0011] Preferably, the driving assembly comprises a support frame fixed to the top of the body, a motor is fixed to the inner side of the support frame, a rotating rod is fixed to the output end of the motor, the lower end of the rotating rod extends to the inner side of the body, a driving gear is fixed to the bottom of the rotating rod, and a connecting assembly is installed on the outer wall of the driving gear. The end of the connecting sleeve away from the rotating rod is equidistantly connected to three driven gears through bearings for rotation, and the three driven gears are all meshed with the outer wall of the driving gear. An annular rack is fixed to the inner side of the body, and the inner side of the annular rack is meshed with the outer wall of the driven gear, and the bottom of the driven gear is fixed to the top of the stirring rod.

[0012] Preferably, the connecting assembly includes a connecting sleeve rotatably connected to the outer wall of the rotating rod through a bearing, and the connecting sleeve is rotatably connected to three driven gears equidistantly through bearings at one end away from the rotating rod, and the three driven gears are all meshed and connected with the outer wall of the driving gear. An annular rack is fixed on the inner side of the main body, and the inner side of the annular rack is meshed and connected with the outer wall of the driven gear, and the bottom of the driven gear is fixed to the top of the stirring rod.

[0013] Preferably, three supporting feet are fixed at equal intervals on the bottom of the body, and anti-slip pads are fixed on the bottom of the supporting feet.

[0014] Preferably, a water inlet pipe is provided on the outer wall of the main body, a sewage discharge pipe is provided on the outer wall of the main body, and a water outlet pipe is provided at the bottom of the main body.

[0015] Compared with the related art, the self-cleaning filter provided by the utility model has the following beneficial effects:

[0016] Since the fan frame stirs in one direction, this may cause impurities and particulate matter to accumulate on one side or in a certain area of ​​the fan frame's rotation direction. This local accumulation will reduce the filtration efficiency because impurities may clog the filter screen or pores and reduce the flow area. In addition, stirring in a single direction may not be able to evenly clean the entire inside of the filter. Some areas may be fully cleaned while other areas may still accumulate impurities, resulting in inconsistent filtration effects. The filtration mechanism can continuously stir the water and impurities in the filter while the stirring rod rotates and moves, so that they are fully mixed and flowed, which helps to evenly disperse the impurities inside the filter and prevent impurities from excessively accumulating in a certain area, thereby improving the cleaning effect and filtration efficiency. In addition, the rotation of the stirring plate on the stirring rod can also stir the impurities and particulate matter in the filter to prevent them from clogging the filter screen or pores on the filter cartridge, which helps to maintain the patency of the filter cartridge and extend its service life.
