[0026] The transmission mechanism 2 includes a second motor 21, a first pulley 22, a second pulley 23, and a third pulley 24;

[0027] The lifting mechanism 7 includes a lifting plate 71, on which a plurality of symmetrically arranged stirring blades 72 are rotatably connected, and each of the plurality of stirring blades 72 has a driven gear 73 fixedly connected to its shaft.

[0028] like Figure 1 As shown, the top end of the reciprocating screw 6 is rotatably connected to the top wall inside the mixing chamber 3, and the output end of the first motor 4 is fixedly connected to the top end of the reciprocating screw 6, so that the first motor 4 can easily drive the reciprocating screw 6 to rotate.

[0029] like Figure 1 As shown, symmetrically arranged guide rods 15 are fixedly connected inside the mixing chamber 3.

[0030] like Figure 1 As shown, the guide rods 15 are all slidably connected to the lifting plate 71. The slidable connection between the guide rods 15 and the lifting plate 71 facilitates the movement of the lifting plate 71.

[0031] like Figure 6 As shown, the top of the spring 14 is fixedly connected to the bottom of the scraper 13. Multiple round rods 16 are symmetrically arranged and fixedly connected inside the mounting rod 12. The multiple round rods 16 are slidably connected to the scraper 13. The slidable connection between the round rods 16 and the scraper 13 facilitates the movement and guidance of the scraper 13.

[0032] like Figure 4As shown, the second motor 21 is fixedly installed on the outer wall of the flocculation tank 1 near the bottom. There are two first pulleys 22, two second pulleys 23 and two third pulleys 24. The two first pulleys 22 are respectively fixedly connected to one end of the first transmission roller 9, the two second pulleys 23 are respectively fixedly connected to one end of the second transmission roller 10, and the two third pulleys 24 are respectively fixedly connected to one of the first transmission rollers 9 and one of the second transmission rollers 10.

[0034] like Figures 1-6 As shown, when using this utility model, water and coagulant are first sent into the mixing chamber 3 through an external pipe. Then, the first motor 4 is started. The slow rotation of the first motor 4 will drive the main stirring blade 5 to rotate. The rotation of the main stirring blade 5 will stir the inside of the mixing chamber 3 and drive the reciprocating screw 6 to rotate. The rotation of the reciprocating screw 6 will drive the lifting plate 71 to move upward. The guide rod 15 guides the movement of the lifting plate 71. The upward movement of the lifting plate 71 will drive multiple secondary stirring blades 72 to move together. The driven gear 73 will also move together. The movement of the driven gear 73 will rotate due to its connection with the rack 8. At this time, the secondary stirring blades 72 moving upward will rotate during the upward movement. The rotating and moving secondary stirring blades 72 will cooperate with the main stirring blade 5 to fully mix the water and coagulant inside the mixing chamber 3.

The first pulley 22 will drive the other first pulley 22, the first transmission roller 9, and the third pulley 24 to rotate via a belt. At this time, the third pulley 24 will drive the other third pulley 24 and the second transmission roller 10 to rotate via a belt. The second transmission roller 10 will drive one of the second pulleys 23 to rotate. The second second pulley 23 will drive the other second pulley 23 and the second transmission roller 10 to rotate via a belt. At this time, the two first transmission rollers 9 and the two second transmission rollers 10 rotate together. Both tracks 11 will drive the mounting rod 12 and scraper 13 to rotate towards the bottom wall of the flocculation tank 1. The rotating scraper 13 will abut against the inner bottom wall of the flocculation tank 1. At this time, the abutting force will push the scraper 13 back into the mounting rod 12. The scraper 13 is guided by the round rod 16. The movement of the scraper 13 will compress and contract the spring 14. At this time, the restoring force of the spring 14 will increase the abutting force of the scraper 13 against the inner bottom wall of the flocculation tank 1. The continuously rotating tracks 11 will drive the scraper 13 to scrape up the sludge accumulated on the inner bottom wall of the flocculation tank 1, so that the sludge continues to flow with the water flow, preventing a large amount of sludge from accumulating on the inner bottom wall of the flocculation tank 1.
