the upstream water flow enters the shell 1, the water flow is discharged from the right end of the shell 1 through the filter plate 3 and the filter screen 9 under the suction action of the pump body, when the water flow passes through the filter plate 3, a part of impurities can be filtered through the gradually reduced inner diameter of the conical filter hole 4, then a part of impurities enter between the filter plate 3 and the filter screen 9 through the conical filter hole 4 and are blocked by the filter screen 9, and meanwhile, the filter screen 9 also moves rightwards under the impact action of the water flow and compresses the first spring 10 through the sliding sleeve 8;
when the pump body stops pumping, water flow also stops flowing, at the moment, the filter screen 9 and the sliding sleeve 8 reset under the elastic force action of the first spring 10 and impact on the filter screen 3 through the impact rod 11, the filter screen 3 vibrates when impacted, under the vibration action, impurities blocked and adhered in the conical filter hole 4 are vibrated and slide down along the conical filter hole 4, the filter screen 9 and the impact rod 11 impact on the filter screen 9 and vibrate to generate vibration, and impurities in the mesh holes of the filter screen 9 vibrate to fall between the filter screen 3 and the filter screen 9 (or on the right side of the filter screen 9), so that the filter screen 3 and the filter screen 9 can be cleaned simultaneously through impact when the filter screen 9 resets, the automatic cleaning effect is achieved, and smoothness of the filter screen 3 and the filter screen 9 is guaranteed;
because the inner diameter of the conical filtering hole 4 is gradually reduced from left to right, impurities filtered by the filtering net 9 are all positioned between the filtering plate 3 and the filtering net 9, when water flows in the water inlet flow passage 2, the filtering net 9 is pushed to drive the sealing plate 13 to move, the sealing plate 13 moves the slag discharging holes 14 formed in the sealing plate 13 to be staggered with the slag discharging holes 15 on the inner bottom wall of the water inlet flow passage 2, and the slag discharging holes 15 can be blocked by the sealing plate 13;
when water flow does not flow in the water inlet flow passage 2, the filter screen 9 is in the original position, the slag discharging hole 14 formed in the sealing plate 13 is superposed with the slag discharging hole 15 on the inner bottom wall of the water inlet flow passage 2, and at the moment, impurities slowly precipitate, so that the impurities can enter the collecting box 18 through the slag discharging hole 14, the slag discharging hole 15 and the bottom pipe 16, and the filtered impurities are automatically discharged;
when water flows in the water inlet flow channel 2, the impact blades 24 can drive the rotating roller 23 to rotate, the rotating roller 23 rotates to drive the vertical shaft 25 to rotate, the vertical shaft 25 rotates to drive the eccentric wheel 31 arranged on the vertical shaft to rotate, and when the eccentric wheel 31 rotates, the push plate 32 can be circularly pushed leftwards;
the push plate 32 is pushed leftwards to drive the valve plate 34 to move through the push rod 33, the valve plate 34 moves to compress the second spring 36, and simultaneously, the valve hole 35 formed in the valve plate coincides with the water outlet hole 28 and the water outlet pipe 29, so that the valve hole 35 can be intermittently coincided with the water outlet hole 28 and the water outlet pipe 29 through the rotation of the eccentric wheel 31; when the valve hole 35 is coincident with the water outlet hole 28 and the water outlet pipe 29, the water treatment agent in the storage tank 26 can be discharged through the water outlet hole 28, the valve hole 35 and the water outlet pipe 29, enter the water inlet flow channel 2 and be mixed with water flow, so that the purpose of automatically adding the agent is achieved, and the agent adding treatment can be conveniently and efficiently carried out on the water inlet flow;
when the vertical shaft 25 rotates to drive the eccentric wheel 31 mounted on the vertical shaft to rotate, the driving wheel 37 is also driven to rotate, the driving wheel 37 rotates to drive the driven wheel 39 to rotate through the synchronous belt 38, the driven wheel 39 rotates to drive the stirring shaft 40 and the stirring rod 41 to rotate, and the stirring rod 41 rotates to stir water treatment agents in the storage tank 26, so that the solution is more uniform, and the treatment effect is prevented from being influenced by precipitation.
