After the filtered liquid is added to the interior of the sector-shaped cavity 7, the sliding cover plate 9 is slid in the reverse direction to seal the sliding cover plate 9 and the sector-shaped cavity 7. When there is liquid above the sector-shaped filter screen, it will be filtered slowly. The pressure control valve 16 is opened, and the air pump 14 works to pump gas into the top of the sector-shaped cavity 7 through the L-shaped tube 15, so that the gas pressure in the upper space of the sector-shaped cavity 7 is gradually increased, thereby accelerating the filtered liquid to pass through the sector-shaped filter screen of the target aperture, and the filtered liquid will fall into the interior of the barrel body 17 After the liquid filtration is completed, the pressurization control valve 16 is closed, the air pump 14 stops working, the control motor 5 works, and the output shaft of the control motor 5 drives the rotating shaft 3 below to rotate, so that the fan-shaped filter screen of the target aperture is located between the upper cover plate 6 and the lower cover plate 10.

The gas enters the lower cover plate 10 and passes through the used fan-shaped filter screen and is finally discharged from the gap of the upper cover plate 6. In the process, the particles and impurities that block the used fan-shaped filter screen will be taken out, thereby cleaning the blockage of the fan-shaped filter screen and making the fan-shaped filter screen reusable.

[0022] The filter group 4 is composed of a plurality of sector-shaped filter screens and a baffle, the filter apertures of the plurality of sector-shaped filter screens are different, and the plurality of sector-shaped filter screens and the baffle are of the same shape and size.

[0023] Among them, the upper end of the L-shaped tube 15 is connected with the interior of the fan-shaped cavity 7, the fan-shaped cavity 7 is adapted to the sliding cover plate 9 and a sealed space is formed therebetween, and fan-shaped holes are provided on the right side of the barrel cover 1 and the barrel body 17.

Its function is that after the filtered liquid is added to the inside of the fan-shaped cavity 7, the sliding cover plate 9 is slid in the reverse direction to seal the sliding cover plate 9 and the fan-shaped cavity 7. When there is liquid above the fan-shaped filter net, it will be slowly filtered, the pressure control valve 16 is opened, and the air pump 14 works to pump the gas into the top of the fan-shaped cavity 7 through the L-shaped tube 15, so that the gas pressure in the upper space of the fan-shaped cavity 7 gradually increases, thereby accelerating the filtered liquid to pass through the fan-shaped filter net of the target aperture, and the filtered liquid will fall into the inside of the barrel body 17.

[0024] Among them, the filter group 4 has the same diameter and thickness values ​​as the installation cavity 2, and the output shaft of the control motor 5 is fixedly connected to the top of the rotating shaft 3.

[0025] Working principle:

[0026] Before the device is used, the air intake control valve 13 and the pressure control valve 16 are in a closed state, and the baffle in the rotating shaft 3 is located directly below the fan-shaped cavity 7.

[0027] When the device is used, a sector filter with a suitable filter aperture is selected, the motor 5 is controlled to work, and the output shaft of the motor 5 is controlled to drive the rotating shaft 3 below to rotate, so that the sector filter with the target aperture is located directly below the sector cavity 7, the motor 5 is controlled to stop working, and the sliding cover plate 9 is slid. The sliding cover plate 9 rotates around the fixed seat 8, and the sliding cover plate 9 is misaligned with the upper part of the sector cavity 7 to form an opening, so that the required filtered liquid can be added to the interior of the sector cavity 7. The liquid added to the interior of the sector cavity 7 must not exceed the upper end of the L-shaped tube 15. After the filtered liquid is added to the interior of the sector cavity 7, the sliding cover plate 9 is slid in the opposite direction to seal the sliding cover plate 9 and the sector cavity 7. When there is liquid above the sector filter, it will be filtered slowly, the pressurization control valve 16 is opened, and the air pump 14 is operated to pump gas into the top of the sector cavity 7 through the L-shaped tube 15, so that the gas pressure in the upper space of the sector cavity 7 gradually increases, thereby accelerating the filtered liquid to pass through the sector filter with the target aperture, and the filtered liquid will fall into the interior of the barrel body 17.

[0028] After the liquid is filtered, the pressure control valve 16 is closed, the air pump 14 stops working, the control motor 5 starts working, and the output shaft of the control motor 5 drives the rotating shaft 3 below to rotate, so that the fan-shaped filter screen of the target aperture is located between the upper cover plate 6 and the lower cover plate 10. The air intake control valve 13 is opened, and the air pump 14 starts working to pump the gas into the lower cover plate 10 through the air intake pipe 12 and the air intake cavity 11. The gas enters the lower cover plate 10 and passes through the used fan-shaped filter screen and is finally discharged from the gap of the upper cover plate 6. In the process, the particles and impurities that block the used fan-shaped filter screen will be taken out, so that the blockage of the fan-shaped filter screen can be cleaned, so that the fan-shaped filter screen can be reused.

[0029] After the fan-shaped filter screen is cleaned, the air intake control valve 13 is closed, the air pump 14 stops working, the control motor 5 starts working, and the output shaft of the control motor 5 drives the rotating shaft 3 below to rotate, so that the baffle is located directly below the fan-shaped cavity 7, separating the barrel cover 1 and the barrel body 17, thereby obtaining the filtered liquid inside the barrel body 17.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
