[0025] A wastewater treatment device using an iron salt flocculant comprises a motor 1, wherein a rotating shaft 2 is fixedly connected to the end of the main shaft of the motor 1, a first bearing 3 is fixedly connected to the outer side of the rotating shaft 2, a fixed shell 4 is fixedly connected to the outer side of the first bearing 3, a connecting column 5 is fixedly connected to the fixed shell 4 on the side close to the motor 1, a second bearing 6 is fixedly connected to the inner side of the fixed shell 4, the inner side of the fixed shell 4 is through-connected to a feed pipe 7, a storage box 8 is fixedly connected to the other end of the feed pipe 7, a hole 9 is provided on the inner side of the rotating shaft 2, a scraper 10 is fixedly connected to the outer side of the rotating shaft 2, a stirring rod 11 is through-connected to the inner side of the rotating shaft 2, a semi-arc tube 12 is fixedly connected to the end of the stirring rod 11 away from the rotating shaft 2, a limiting ring 13 is fixedly connected to the inner side of the stirring rod 11, a material guide head 14 is slidably connected to the inner side of the stirring rod 11, and an elastic sheet 15 is fixedly connected to the inner side of the stirring rod 11.

[0026] There are several elastic sheets 15, which are evenly distributed on the inner side of the stirring rod 11 with the center of the axis of the stirring rod 11. The side of the elastic sheet 15 is fan-shaped, and the two adjacent elastic sheets 15 on the inner side of the stirring rod 11 are tightly attached to prevent the impurities in the wastewater from clogging the guide head 14 when the rotating shaft 2 is not working; there are several stirring rods 11, which are evenly distributed on the outer side of the rotating shaft 2. The stirring rod 11 is inclined at an angle to the rotating shaft 2 toward the side away from the motor 1, so as to facilitate the smooth discharge of the iron salt flocculant inside it; the hole 9 is arranged on the inner side of the fixed shell 4, and the lower side of the hole 9 is on the same horizontal plane as the upper side of the second bearing 6. The hole 9 is connected to the cavity opened on the inner side of the rotating shaft 2 and the channel opened on the inner side of the stirring rod 11 in sequence, and the iron salt flocculant can be injected into the wastewater through the rotating shaft 2 and the stirring rod 11; the scraper 10 is arranged on the outer side of the hole 9, the cross section of the scraper 10 is arc-shaped, the vertical section of the scraper 10 is also arc-shaped, and the scraper 1 The curvature of the vertical section of the second bearing 6 is the same as that of the hole 9. The scraper 10 is close to the outer side of the second bearing 6, so as to facilitate the iron salt flocculant accumulated on the inner side of the fixed shell 4 to be transported to the inner side of the rotating shaft 2 through the hole 9. The guide head 14 is arranged between the limit ring 13 and the elastic sheet 15. The maximum outer diameter of the guide head 14 is the same as the maximum outer diameter or the maximum inner diameter of the limit ring 13. The inner side of the guide head 14 is through. The end of the guide head 14 close to the elastic sheet 15 is in the shape of a pillar. The minimum inner diameter of the limit ring 13 is the same as that of the elastic sheet 15. The maximum inner diameters of the guide heads 14 are the same, which can limit the moving range of the guide heads 14 and facilitate the guide heads 14 to protrude from the stirring rod 11 under the centrifugal force of the rotating shaft 2; the inner arc of the scraper 10 and the outer arc of the semi-arc tube 12 are facing the counterclockwise rotation direction of the rotating shaft 2, and the semi-arc tube 12 is expanded in the direction away from the stirring rod 11, which can prevent impurities in the wastewater from clogging the guide head 14 protruding from the stirring rod 11 and affecting the smooth discharge of the iron salt flocculant inside the guide head 14.

[0027] Working process: During use, the equipment is powered by an external power supply. When the equipment is used to flocculate wastewater, the section of the rotating shaft 2 below the second bearing 6 is placed in the wastewater. At this time, the fixed and restricted motor 1 can be started, and the motor 1 drives the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the scraper 10 and the stirring rod 11 fixedly connected to the outside thereof to rotate. Because the rotating shaft 2 is fixedly connected to the fixed shell 4 through the first bearing 3 and the second bearing 6 with a sealing effect, and the fixed shell 4 is fixedly connected to the motor 1 at a fixed position through the connecting column 5, the fixed shell 4 has In a relatively stable static state, the storage box 8 can transport the iron salt flocculant to the inner side of the fixed shell 4 through the feed pipe 7, and the iron salt flocculant transported to the inner side of the fixed shell 4 is accumulated in the bottom of the inverted column of the fixed shell 4, so that the rotating shaft 2 drives the scraper 10 fixedly connected to the outer side thereof to rotate, and the arc-shaped scraper 10 can gradually squeeze the iron salt flocculant accumulated on the second bearing 6 into the hole 9 opened in the rotating shaft 2, and continuously transport it to the cavity inside the rotating shaft 2, and at the same time, a plurality of stirring rods 11 arranged obliquely on the outer side of the rotating shaft 2 are connected to the rotating shaft 2. The iron salt flocculant that enters the rotating shaft 2 can enter the inner side of the stirring rod 11 again, and slide on the inner side of the stirring rod 11 under the centrifugal force of the rotating shaft 2 rotating counterclockwise, and gradually move away from the rotating shaft 2. The iron salt flocculant that slides on the inner side of the stirring rod 11 first passes through the limit ring 13 fixedly connected to the stirring rod 11, and then enters the inner side of the guide head 14. Then, the iron salt flocculant that enters the inner side of the guide head 14 moves together with the guide head 14 in the direction away from the rotating shaft 2 under the centrifugal force of the rotating shaft 2. The guide head 14 gradually approaches the elastic sheet 15 and pushes the elastic sheet 15. The sheet 15 exerts a thrust, causing the elastic sheet 15 to deform. At this time, part of the guide head 14 protrudes from the stirring rod 11, and is still within the range of the semi-arc tube 12 fixedly connected to the outside of the stirring rod 11. As the stirring rod 11 stirs the wastewater, the iron salt flocculant is continuously and evenly dispersed in the wastewater from the guide head 14, thereby achieving the simultaneous addition of the iron salt flocculant to the wastewater and the full dissolution and mixing of the iron salt flocculant in the wastewater, effectively reducing the time consumed in wastewater treatment and avoiding the low dissolution efficiency of the iron salt flocculant caused by the simultaneous injection of a large amount of iron salt flocculant into the same area of ​​the wastewater.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
