The filter plate is a ceramic filter plate or a stainless steel orifice plate processed by laser drilling.

The side wall of the filter seat below the filter plate is integrally connected with a drain joint 9311, and the side wall of the filter plate positioning part is provided with a water outlet corresponding to the position of the drain joint; the drain joint is connected with a solenoid valve 95 .

The transition position between the water inlet joint and the filter plate positioning part forms a step part, and the upper end position of the inner circumference of the water inlet joint is connected with a rotating connecting frame 98, and the middle of the rotating connecting part of the drive shaft and the rotating connecting frame Turn to connect.

A rubber one-way valve plate 933 is provided on the sealing sleeve on the rotating connection portion, and the outer periphery of the one-way valve plate abuts against the step portion on the water inlet joint. When the water flows into the water inlet joint from bottom to top, the one-way valve plate is pushed upward by the water flow and is in a conduction state. When the water flows from the top of the filter plate through the filter plate to the bottom of the filter plate, the outer periphery of the one-way valve plate is against the step. up and in a closed state.

A scraper frame 98 for scraping dirt attached to the lower end surface of the filter plate is rotatably provided on the rotary connection portion; the scraper frame includes an inner connection ring 981 sleeved outside the rotary connection portion. An outer connecting ring 985 arranged coaxially with the inner connecting ring, and more than two connecting ribs 982 integrally connected between the outer connecting ring and the inner connecting ring, the upper end of each connecting rib is fixedly connected with an elastic scraper 983, so A thrust spring 98a for pushing the scraper up is installed between the lower end of the inner connecting ring and the one-way valve plate. The inner wall of the inner connecting ring is formed with an inner protrusion (not shown in the figure) that is threadedly connected with the driving threaded part. ).

The axial blades are lower on the left and higher on the right, and the driving thread part is a left-handed thread.

The motor, Hall sensor and solenoid valve are respectively electrically connected to the controller; in normal working condition, the controller drives the motor to rotate clockwise, and the axial flow vanes generate an upward thrust on the water in the water inlet pipe; at this time, the drive threaded part The lower end of the scraper is in a state of abutting but not engaging with the inner protrusion of the scraper, and the scraper is far away from the filter plate. The scraper is in a non-working state like this.

When the filter plate is clogged, the pressure difference between the upper and lower sides of the axial flow blade increases. When the pressure difference is greater than the spring force of the spring, the overall compression spring of the water wheel moves downward, so that the permanent magnet moves downward and approaches the Hall. Hall sensor, after the Hall sensor detects the signal, the controller controls the motor to rotate counterclockwise, so that the inner protrusion of the scraper frame is engaged with the driving thread part under the push of the thrust spring, so that the scraper is against the filter plate, and When the scraper frame is blocked by the filter plate and cannot continue to move upward, the scraper frame rotates with the drive shaft to scrape off the dirt on the filter plate.

At the same time, the controller controls the solenoid valve to open, and the axial flow vane rotates counterclockwise to drive the water to backwash the filter plate from top to bottom. At the same time, because the check valve is in a closed state, the water with dirt is discharged from the check valve. After 10-60 seconds, the controller controls the solenoid valve to close, and controls the motor to rotate clockwise again to enter the working state.

When the motor of the filter pump in the present invention rotates clockwise, both the centrifugal water wheel and the axial flow blades are in working condition, and the axial flow blades pump the water upwards, then the water is thrown out by the centrifugal water wheel, and finally discharged from the water outlet joint. In this state, the axial flow blades play an auxiliary role in the pumping of the centrifugal water wheel; when the motor rotates counterclockwise, the axial flow blades drive the water up and down to wash the filter plate countercurrently, and the water with dirt passes through the solenoid valve Discharge, so that the filter pump can pump in filtered relatively clean water, and can be self-cleaning, extending the maintenance-free use time. In addition, in the present invention, when the filter plate is clogged, the (switch type) Hall sensor cooperates with the axial flow vane to drive the water wheel to move as a whole to judge whether the filter plate is clogged or not. In other words, the control becomes simple. In addition, the scraper works only when the filter plate is backwashed, and does not work when the filter pump is in normal operation, which will not significantly increase the energy consumption of the motor.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or perform equivalent replacements for some of the technical features. Within the spirit and principles of the present invention, any modifications, equivalent replacements, improvements, etc., shall be included in the protection scope of the present invention.
