During the downward movement of the slide post 761, the collar 73 is driven to rotate in one direction through the close contact with the spiral slide rail 731, during the upward movement of the slide post 761, the collar 73 is driven to rotate in the other direction through the close contact with the spiral slide rail 731, and the rocker 74 is driven to move in a following manner, so that the rotation of the output shaft 72 of the motor table 71 in one direction finally realizes that the rocker 74 generates intermittent reciprocating swinging movement in a certain angle by taking the collar 73 as an axis, and the hollow baffle 64 is driven to move due to the close contact sliding of the snap ring 66 in the second slide rail 741, and meanwhile, the hollow baffle 64 can only slide in the sliding chamber 61, so that the hollow baffles 64 at two sides have the following effects on water flow in the sliding chamber 61: when the slider 76 is positioned at the upper end such that the collar 73 and the rocker 74 are rotated by the maximum angle in one direction, the hollow baffle plate 64 positioned at one side of the main water inlet pipe 3 will slide to the rear end of the sliding chamber 61 and close the second water inlet branch pipe 32, the hollow baffle plate 64 positioned at one side of the main water outlet pipe 4 will slide to the front end of the sliding chamber 61 and close the first water outlet branch pipe 41, at which time water can only enter from the first water inlet branch pipe 31 and flow out from the second water outlet branch pipe 42, at which time water will flow from the front end to the rear end in the reaction cylinder 1 through the water permeable grating 8 and the packing, the motor table 71 continues to operate until the slider 76 moves to the middle of the vertical sliding rail 75, at which time the hollow baffle plates 64 at both sides move to the middle position of the sliding chamber 61, at which time the hollow baffle plate 64 closes all the through holes 62, the water flow is suspended, the motor table 71 continues to work, the hollow baffle plate 64 positioned at one side of the main water inlet pipe 3 moves towards the front end of the sliding chamber 61, so that the through hole 62 positioned at the second water inlet branch pipe 32 is gradually opened, meanwhile, the through hole 62 positioned at the first water outlet branch pipe 41 at the other side is gradually opened, so that the water flow enters from the second water inlet branch pipe 32, flows towards the front end through the water permeable grid 8 and the filler at the rear end of the reaction cylinder 1 and flows out of the first water outlet branch pipe 41, and the water flow moves towards one direction in the reaction cylinder 1 in the period between two nodes, namely the period between the rocker 74 and the sliding chamber 61 and the period between the two nodes, and the water flow moves towards the other direction in the reaction cylinder 1 in the period between the two nodes, and circulates and reciprocates;
The through holes 62 are gradually opened and gradually closed, so that the switching of the water flow direction also accords with the water flow movement rule, namely the water flow is gradually increased in one direction after being instantly static, the maximum flow is gradually reduced after a period of time, the water flow is instantly static and then the same movement rule is realized in the other direction, so that the movement of the water flow is more stable, the water flow disturbance does not occur, the running of the equipment is more stable, the hollow baffle plate 64 moves in the sliding chamber 61, the water flow can freely flow in the hollow baffle plate 64 because the hollow baffle plate 64 is a hollow cavity with two open ends, the hollow baffle plate 64 does not squeeze the water flow to generate resistance when moving towards one end of the sliding chamber 61, and the hollow baffle plate 64 is tightly attached to the sliding chamber 61, so that the through holes 62 can be closed when the water flow in the hollow baffle plate 64 passes;
titanium dioxide on packing between the water permeable grids 8 can generate electron and hole pairs on the surface through the irradiation of the annular ultraviolet lamp belt 9, the electron and hole pairs have reduction and oxidation capacities respectively, can react with pollutants in water, and realize purification of sewage.
