The shielding pump also comprises a cleaning mechanism 5, wherein the cleaning mechanism 5 comprises a guide plate 51, a round rod 52, a connecting plate 53 and a hairbrush 54;

The baffle 51 is disposed in the input port 2, the round bar 52 is rotatably disposed in the input port 2, the connection plate 53 is connected to the round bar 52, and the brush 54 is disposed on the connection plate 53.

The filter screen 4 is arranged in the input port 2, the medium entering the shielding pump body 1 through the input port 2 can be filtered through the filter screen 4, and the filter screen 4 can block large particulate matters or solid impurities, so that the large particulate matters or solid impurities are prevented from entering the shielding pump body 1, and the abrasion and damage risks of the shielding pump body 1 are reduced. For toxic, corrosive or dangerous chemicals, the filtering by the sieve 4 prevents the inside of the canned pump body 1 from increasing the risk of leakage or rupture due to the accumulation of unfiltered substances. And maintenance and cleaning work due to foreign substances can be reduced by the filter screen 4.

Further, the material of the filter screen 4 may be, but not limited to, hastelloy and monel. Both of these alloys remain stable in a variety of chemical environments and do not readily react with the filter media.

The filter screen 4 with the semi-arc structure can be installed in the cylindrical input port 2 in a fitting mode, so that the entered medium can be effectively filtered.

The guide plate 51 is arranged in the input port 2, the round rod 52 is rotatably arranged in the input port 2, the number of the connecting plates 53 is four, the guide plates are equidistantly arranged on the round rod 52, and the brushes 54 are arranged on the connecting plates 53.

In particular operation, as the media enters, the direction of flow of the media may be changed by the baffle 51. Causing the media to flow toward the web 53 at one end and drop onto the web 53. When the medium falls onto the connection plate 53, the connection plate 53 is driven to rotate, so that the round rod 52 rotates. The round rod 52 rotates to drive the connecting plate 53 to rotate, so that the brush 54 is driven to clean the impurities filtered on the upper surface of the filter screen 4.

Further, when the medium falls onto the connection plate 53, the power of the medium falling pushes the connection plate 53 to rotate, thereby causing the round bar 52 to rotate. In this way, the kinetic and gravitational potential energy of the medium is converted into rotational mechanical energy of the round bar 52 while the rotation of the round bar 52 is entirely dependent on hydrodynamic and gravitational forces, requiring no external electrical input. Thereby making it more environment-friendly and energy-saving.

In the specific operation process, impurities at the top end of the filter screen 4 are swept into the filter cartridge 63 through the sewage outlet 41 and the connecting pipe 65 by the brush 54 in the cleaning structure 5, and the swept impurities can be collected intensively through the filter cartridge 63. And when a part of the medium flows into the filter cartridge 65 through the connection pipe 65, the filtering can be performed through the filter cartridge 65, and the filtered medium is re-discharged into the input port 2 through the check valve 68.

When the impurities stored in the filter cartridge 63 need to be cleaned, the rotating rod 66 is rotated by 90 degrees, so that the first sealing plate 67 is caused to seal the connecting pipe 65, and medium and impurities can be prevented from entering the filter cartridge 63. At the same time, the second sealing plate 69 is opened, and the filter cartridge 63 can be taken out, so that convenient cleaning can be performed. After cleaning, the filter cartridge 63 can be placed by placing the connection block 64 on the support block 62.
