Illustratively, the circulating assembly comprises a guide groove 3, the guide groove 3 is arranged on the inner wall of the flocculation cylinder 2, the guide groove 3 is spirally arranged in the flocculation cylinder 2, and one end of the water delivery pipe 12, which is positioned in the flocculation cylinder 2, is communicated with the guide groove 3;
the rotating pipe 31 is rotatably arranged inside the flocculation cylinder 2, and stirring blades 32 which are uniformly distributed are fixedly arranged on the rotating pipe 31;
the guide pipe 33 is fixedly connected in the flocculation cylinder 2, the guide pipe 33 is positioned inside the rotating pipe 31, a backflow tank 34 is formed between the guide pipe 33 and the rotating pipe 31, the rotating pipe 31 is provided with sedimentation holes 35 which are uniformly distributed, the sedimentation holes 35 correspond to the stirring blades 32 one by one, and the sedimentation holes 35 are used for communicating the backflow tank 34 with the inner cavity of the flocculation cylinder 2;
the flocculation cylinder 2 is obliquely installed, and the height above the ground of the flocculation cylinder 2 is smaller along with the closer distance to the water delivery pipe 12;
the flocculation cylinder 2 is obliquely installed, the circulating component is parallel to the inner cavity of the flocculation cylinder 2, namely, the rotating pipe 31 and the flocculation cylinder 2 are coaxially designed, the dynamic filtering component is installed at the bottom of the flocculation cylinder 2, when the water suction pump 1 works, water flow is continuously pumped into the flocculation cylinder 2 through the water feeding pipe 12, the water feeding pipe 12 impacts the water flow into the guide groove 3, the guide groove 3 is spirally arranged, so that the water flow is spirally arranged along the flow path of the inner wall of the flocculation cylinder 2 under the action of the guide groove 3, and due to the arrangement of the guide groove 3, after the water flow in the flocculation cylinder 2 is accumulated to a certain height, the flow rate of the water flow close to the inner wall of the flocculation cylinder 2 is obviously higher than the flow rate of the water flow at the center of the flocculation cylinder 2, so that under the impact of the water flow guided by the guide groove 3, the impact force on the end part of the stirring blade 32 fixedly connected to the rotating pipe 31 is larger, and then cause the stirring vane 32 to drive the rotating tube 31 to rotate inside the flocculation cylinder 2, the rotating stirring vane 32 conflicts with the flocculant which moves downwards under the action of gravity, and the movement path of the floc group, therefore, under the action of the stirring vane 32, the flocculant and the floc group are stirred in water, the flocculant and the floc group change more in the flow path of the water flow, and the movement path is longer, so that the flocculant effectively contacts and collides with the water flow, the adsorption effect on impurities and particles in the water flow is enhanced, meanwhile, in the rotating process of the stirring vane 32, the stirring vane 32 has the effect of stirring the lower floc group upwards, the floc group moving to the upper part has the trend of moving downwards under the action of gravity, and the more the water flow rotates and rises more, so under the impact of the water flow, the floc group is not easy to directly settle to the bottom of the flocculation cylinder 2, therefore, the flocs have the trend of moving into the settling holes 35 in the continuous rotating and settling process, enter the reflux tank 34 through the settling holes 35, and have the trend of moving to the lower part of the flocculation cylinder 2 along the reflux tank 34 under the action of gravity, and because the reflux tank 34 is only communicated with the inner cavity of the flocculation cylinder 2 through the settling holes 35, the water flow in the reflux tank 34 has lower impact effect of the water flow which continuously rotates and spirally flows in the flocculation cylinder 2, thereby reducing the upward impact force on the flocs, facilitating the sedimentation of the flocs to the bottom of the flocculation cylinder 2,
when water flows out of the water supply pipe 12 under the action of the guide groove 3 and spirally rises, small particle impurities fished by the dynamic filtering component and a flocculating agent which does not form a floc group at the bottom of the flocculation cylinder 2 move upwards under the impact of the water flow and gradually form a larger floc group in the process of moving to the upper part of the flocculation cylinder 2, the floc group has the tendency of moving downwards under the action of gravity and is re-settled to the bottom of the flocculation cylinder 2 through the return groove 34 and is fished and discharged by the dynamic filtering component in the settling process, the fished small particles rise again, so that the flocculating agent and the small particle impurities are circulated up and down in the flocculation cylinder 2 until the flocculating agent and the small particle impurities are discharged by the dynamic filtering component in the circulating process, on the one hand, when the flocculating agent is not fully flocculated and agglomerated to form the floc group in the dynamic circulating process, the flocculant is discharged to the outside, the flocculation effect of the flocculant cannot be fully exerted, and on the other hand, the collision and contact probability of the flocculant and impurity particles in water flow is increased in the circulating reciprocating process, so that the flocculation and agglomeration effects of the flocculant on the impurities in the water flow are enhanced, and the removal effect on the impurities in the water flow is enhanced.
Illustratively, the dynamic filtering assembly comprises a rotating shaft 4, the rotating shaft 4 is rotatably connected inside the flocculation cylinder 2, the rotating shaft 4 extends into the guide pipe 33 and is designed coaxially with the guide pipe 33;
the filter ring 41 is fixedly arranged on the rotating shaft 4, two ends of the filter ring 41 are respectively connected with the inner wall of the flocculation cylinder 2 and the rotating pipe 31 in a rotating and sealing manner, the guide pipe 33 extends into the filter ring 41, and the guide pipe 33 is positioned in the filter ring 41 and is provided with an opening;
the first filter plate 42 is fixedly connected to the filter ring 41, the filter ring 41 is provided with a collection hole 43, the first filter plate 42 extends into the collection hole 43, one end of the first filter plate 42, which is far away from the filter ring 41, is in an L shape, and the first filter plate 42 is attached to the inner wall of the flocculation cylinder 2;
the packing auger 44 is fixedly arranged on the rotating shaft 4, the packing auger 44 is positioned inside the guide pipe 33, and one end of the guide pipe 33, which is far away from the filter ring 41, extends to the outside of the flocculation cylinder 2;
the circulating component and the dynamic filtering component are coaxially arranged in the flocculation cylinder 2, the dynamic filtering component is arranged below the circulating component, when the water delivery pipe 12 pumps water to the flocculation cylinder 2, the water delivery pipe 12 is positioned in the flocculation cylinder 2 and is Y-shaped, one end of the water delivery pipe extends into the guide groove 3 and is arranged along the tangential direction of the guide groove 3, the other end of the water delivery pipe extends into the flocculation cylinder 2 and is opened towards the direction of the filtering ring 41, the water flows in the flocculation cylinder 2 along the guide groove 3, the first filtering plate 42, the filtering ring 41 and the rotating shaft 4 rotate under the impact and pushing action of the water flow, and in the rotating process of the first filtering plate 42, the water flow is in motion interference with the flocs deposited from the upper part, so that under the influence of the upward pushing of the first filtering plate 42 and the self gravity of the flocs, part of the flocs move towards the filtering ring 41 along the first filtering plate 42 and finally enter the collecting holes 43 on the filtering ring 41, and then enter the inner cavity of the filter ring 41, because the auger 44 is arranged on the rotating shaft 4, and the auger 44 extends to the inside of the guide pipe 33, the auger 44, the rotating shaft 4 and the guide pipe 33 form a spiral conveyor, the floc entering the inner cavity of the filter ring 41 enters the inner cavity of the guide pipe 33 through the opening of the guide pipe 33, and under the action of the auger 44 which rotates continuously, the floc and part of water flow to the end part of the guide pipe 33 to move, so that the floc can be discharged through the opening of the guide pipe 33 positioned outside the flocculation cylinder 2 under the conveying of the auger 44,
specifically, because the water flow pumped by the water pump 1 has a certain kinetic energy, after the water flow enters the flocculation cylinder 2, along with the increase of the flow path, the kinetic energy of the water flow is gradually weakened, so that the water flow impact force at the bottom of the flocculation cylinder 2 is large, the water flow impact force at the top is small, so that the rotation speed of the first filter plate 42 is high, and the rotation speed of the stirring blade 32 at the top is relatively slow, on one hand, the first filter plate 42 at the bottom has a high rotation speed, so that the formed flocs can be collected, and the rotation speed of the stirring blade 32 at the top is mild, so that the stability of the flocs forming can be enhanced, on the other hand, the rotation speed of the first filter plate 42 is high, so that the rotation speeds of the rotating shaft 4 and the auger 44 are relatively high, and further, the conditions of conveying the collected flocs upwards and discharging outwards are met,
meanwhile, because the first filter plates 42 are uniformly arranged on the filter ring 41, only the first filter plate 42 corresponding to the water feeding pipe 12 is impacted by water flow, and the impact direction of the water flow is opposite to the filtering direction of the first filter plate 42, thereby completing the back washing function of the first filter plate 42, and other first filter plates 42 which are not directly opposite to the water feeding pipe 12 are driven by the filter ring 41 to rotate, therefore, the first filter plates 42 which are not directly impacted by the water flow of the water feeding pipe 12 play roles of rotating, filtering and catching, and because the flow velocity of the water flow in the flocculation cylinder 2 is gradually reduced from the inner wall to the center, thereby facilitating the first filter plates 42 to collect flocs, because the first filter plates 42 adopted by the application are made of stainless steel screen meshes or filter cloth, in the rotating process of the first filter plates 42, flocculants and the like smaller than the meshes of the first filter plates 42 can permeate through the first filter plates 42, the water flow moves upwards under the entrainment of the guide groove 3 and deposits downwards again after forming flocks.
Illustratively, the second filter plate 5 is fixedly connected to one side of the first filter plate 42, which is far away from the filter ring 41, a partition plate 51 is fixedly connected to the filter ring 41, the partition plate 51 is positioned in the middle of the first filter plate 42 and the second filter plate 5, the partition plate 51 is not in contact with the first filter plate 42 and the second filter plate 5, and the first filter plate 42, the second filter plate 5 and the partition plate 51 form a washing flow passage 52;
through setting up second filter 5 and baffle 51, and second filter 5 all adopts the same material of first filter 42 with baffle 51 to make, at the rotatory in-process of first filter 42, second filter 5 at first contacts with the wadding group in the rivers, receive second filter 5 to stir, the effect of interception, cause the wadding group to subside in second filter 5 is close to direction of rotation one side, along with the continuous upwards rotation of second filter 5, cause the wadding group to move to filter ring 41 direction under the action of gravity, at this moment under the hindrance effect of baffle 51, the wadding group can't directly move to in the collecting hole 43, along with the second filter 5 move to the top and along with the rotatory in-process that moves down gradually, the wadding group flows in the interval of second filter 5 with baffle 51, and when second filter 5, baffle 51 move to the lowest, the wadding group subsides to baffle 51, At the juncture of the first filter plate 42 and the second filter plate 5, as the first filter plate 42 and the second filter plate 5 rise again, the flocs at this time settle and align with the collecting holes 43, finally fall into the collecting holes 43,
after the flocs are intercepted by the second filter plate 5 and then enter the flushing flow passage 52 formed by the first filter plate 42, the second filter plate 5 and the partition plate 51, the flocs can enter the collecting holes 43 after undergoing a rotation period, and in the whole rotation period, the first filter plate 42, the second filter plate 5 and the partition plate 51 inevitably complete one back flushing with the water conveying pipe 12, and when the flocs are in the flushing flow passage 52 during back flushing, the flocs are located in the flushing flow passage 52, at the moment, the flocs have small volume and are not filtered enough, and under the action of the water flow of the back flushing, the flocs penetrate through the first filter plate 42, the second filter plate 5 and the partition plate 51 and then are separated from the flushing flow passage 52, so that when the flocs are collected, the flocs are flushed, on one hand, a large amount of collected flocs and flocculant colloids are in contact with the water flow pumped in the water conveying pipe 12, and further the impurities in the water flow pumped in the water conveying pipe 12 are intercepted by the flocs, and then the interception effect on particles in the water flow is enhanced, on the other hand, the collected floccules and flocculant colloid are screened, and then the floccules which are not completely flocculated, agglomerated or have small aggregate volume are removed, so that the probability that the flocculant is removed without completely playing a role is reduced, and further the purification and flocculation effects of the flocculant on the water body are enhanced.
Illustratively, the filtering ring 41 is fixedly connected with an annular baffle 53, and the annular baffle 53 is fixedly connected with the first filtering plate 42, the second filtering plate 5 and the partition plate 51;
through fixed connection annular breast board 53 on filtering ring 41, and annular breast board 53 and first filter 42, second filter 5, the equal fixed connection of baffle 51, and the runner 52 that will wash of annular breast board 53 is whole to be covered, consequently at annular breast board 53 and first filter 42, second filter 5, the synchronous pivoted in-process of baffle 51, annular breast board 53 can cooperate flocculation section of thick bamboo 2 inner wall and first filter 42, second filter 5, baffle 51, seal washing runner 52, and then can reduce at the washing in-process, the probability that the wadding of collection directly flows out, annular breast board 53 can be at first filter 42 simultaneously, second filter 5 is rotatory, the in-process of collection wadding, form and shelter from the effect, reduce behind the rivers disturbed, the probability that the wadding flutters to flocculation section of thick bamboo 2 top under the effect of disturbing rivers.
