[0027] Through the technical scheme, the first rotating shaft 7 rotates to drive the extrusion plate 25 to rotate, so that the plurality of stirring blades 36 rotate to stir the mixed wastewater, so that the wastewater forms a vortex, and then the motor 6 is turned off to stop the stirring blades 36 from rotating, at this time, the centrifugal force of the wastewater disappears, the flocculation in the wastewater moves to the center, and falls into the discharge pipe 10, and is supported and stacked by the supporting plate 11, the motor 6 is controlled to move downward by the first hydraulic cylinder 4, the first rotating shaft 7 is driven to move downward, the extrusion plate 25 moves downward and enters the discharge pipe 10 to block the discharge pipe 10, the flocculation on the top of the supporting plate 11 is extruded by the extrusion plate 25, the extrusion plate 25 moves downward at the same time, the second spring 37 is compressed, and the wastewater contained in the flocculation is filtered by the filter plate 27 as the extrusion plate 25 is extruded downward, so that the wastewater passes through the filter plate 27 and enters the cavity 26, and is discharged from the liquid discharge pipe 28 to the tank 1 again through the one-way valve 29, thereby saving the discharge of the wastewater, the wastewater remaining in the tank 1 can be recycled in subsequent use, and the remaining flocculation is left between the extrusion plate 25 and the supporting plate 11, the bottom of the supporting plate 11 is supported by the first spring 30 cooperating with the clamping block 31, the bottom of the supporting plate 11 abuts against the inclined surface on the top of the clamping block 31, and as the extrusion plate 25 continues to move downward, the clamping block 31 is moved by the supporting plate 11 when the second spring 37 is compressed to the limit, the first spring 30 is compressed, the clamping block 31 is no longer limited, and the supporting plate 11 moves downward and out of the tank 1 under the action of the second spring 37, the flocculation on the top of the supporting plate 11 slides along the inclined surface, thereby helping to clean the flocculation in the tank 1, after the flocculation on the top of the supporting plate 11 is discharged, the motor 6 is controlled to move upward by the first hydraulic cylinder 4, so that the first rotating shaft 7 and the extrusion plate 25 move upward, and the supporting plate 11 moves upward, and when the supporting plate 11 moves to the clamping block 31, the bottom of the clamping block 31 is abutted, and the clamping block 31 is moved under the extrusion of the supporting plate 11, so that the supporting plate 11 passes through the clamping block 31 upwardly.

[0028] Specifically, the bottom of the supporting plate 5 is fixedly connected with a plurality of second hydraulic cylinders 32 at equal intervals, the bottoms of the plurality of second hydraulic cylinders 32 are fixedly connected with a rotating ring 33, the top of the rotating ring 33 is provided with an annular inclined surface, the bottom of the rotating ring 33 is rotatably connected with a scraper 34, the scraper 34 is provided in an annular shape, and the rotating ring 33 and the scraper 34 are attached to the inner wall of the tank 1; the stirring rod 9 is arranged in the interior of the scraper 34 and is fixedly connected with the scraper 34.

[0029] Through the above technical scheme, after the flocculant is mixed with the wastewater, the second hydraulic cylinder 32 controls the up-down movement of the rotating ring 33, drives the up-down movement of the scraper 34, and the flocculation material adhered to the inside of the tank body 1 can be scraped off through the scraper 34. When the scraper 34 is controlled to move downward, the stirring rod 9 can be controlled to move downward and tightly adhere to the bottom of the tank body 1, and the stirring rod 9 can be controlled to rotate to scrape off the flocculation material adhered to the bottom of the tank body 1. The flocculation material adhered to the bottom of the tank body 1 cannot be moved by the action of the centrifugal force alone. If the stirring rod 9 has flocculation material adhered thereto, the second hydraulic cylinder 32 controls the up-down movement of the stirring rod 9 in the wastewater, increases the shearing force between the stirring rod 9 and the wastewater, and can effectively clean the flocculation material adhered to the stirring rod 9. When the flocculation material in the wastewater is controlled to concentrate in the discharge pipe 10, the second hydraulic cylinder 32 controls the scraper 34 and the stirring rod 9 to move out of the wastewater, so as to prevent the stirring rod 9 from hindering the concentration of the flocculation material in the wastewater into the discharge pipe 10.

[0030] Specifically, the bottom of the stirring rod 9 is equidistantly fixedly connected with a plurality of push plates 35, and the push plates 35 are arranged in an arc shape.

[0031] Through the above technical scheme, if a large piece of flocculation material is deposited at the bottom of the tank body 1 and cannot be moved by the centrifugal force, the second hydraulic cylinder 32 controls the stirring rod 9 to slowly move upward, drives the plurality of push plates 35 to slowly move upward, and then controls the plurality of push plates 35 to quickly move downward through the second hydraulic cylinder 32. The impact force formed by the arc surface of the bottom of the push plate 35 can push the large piece of flocculation material at the bottom of the tank body 1 to move to the discharge pipe 10.

[0032] Specifically, the discharging assembly includes a plurality of feeding pipes 16, and the plurality of feeding pipes 16 are equidistantly fixedly installed at the bottom of the storage box 13. The top of the feeding pipe 16 extends to the inside of the storage cavity 14, the bottom of the feeding pipe 16 is fixedly connected with a sleeve 17, and the bottom of the sleeve 17 is fixedly connected with a discharging pipe 18. The bottom of the storage box 13 is fixedly connected with a fixed ring 19, the inner wall of the fixed ring 19 is equidistantly rotatably connected with a plurality of second rotating shafts 20, one end of the second rotating shaft 20 extends to the inside of the sleeve 17 and is fixedly connected with a rotating disc 21, the rotating disc 21 abuts against the inner wall of the sleeve 17, the outer wall of the rotating disc 21 is equidistantly provided with a plurality of discharging grooves 22, and the outer wall of the first rotating shaft 7 is provided with a linkage unit.

[0033] Through the technical scheme, the flocculant in the storage cavity 14 enters the sleeve 17 along the feeding pipeline 16, the first shaft 7 rotates at the same time, drives the first bevel gear 23 to rotate, drives the second bevel gear 24 to rotate, drives the second shaft 20 to rotate, drives the rotating disc 21 to rotate, when the discharging groove 22 on the outer wall of the rotating disc 21 rotates to the feeding pipeline 16, the flocculant in the feeding pipeline 16 enters the discharging groove 22, with the continuous rotation of the rotating disc 21, when the discharging groove 22 containing the flocculant rotates to the discharging pipeline 18, the flocculant in the discharging groove 22 falls into the wastewater in the tank 1 along the discharging pipeline 18, thereby the flocculant in the storage cavity 14 is discharged quantitatively, avoids that the flocculant is not uniformly dispersed due to the one-time excessive feeding, the local concentration is suddenly high, and the flocculation failure is caused.

[0034] In use, the discharge pipe 10 is blocked by the supporting plate 11, the wastewater is introduced into the tank body 1 through the liquid inlet 2, and the flocculating agent is loaded into the storage cavity 14 through the feed inlet 15. The flocculating agent in the storage cavity 14 enters the sleeve 17 through the feed pipe 16. The motor 6 is started, the first rotating shaft 7 is controlled to rotate, the first bevel gear 23 is driven to rotate, the second bevel gear 24 is driven to rotate, the second rotating shaft 20 is driven to rotate, and the rotating disc 21 is driven to rotate. When the discharge groove 22 on the outer wall of the rotating disc 21 rotates to the position of the feed pipe 16, the flocculating agent in the feed pipe 16 enters the discharge groove 22. With the continuous rotation of the rotating disc 21, when the discharge groove 22 containing the flocculating agent rotates to the position of the discharge pipe 18, the flocculating agent in the discharge groove 22 falls into the wastewater in the tank body 1 through the discharge pipe 18. Thus, the flocculating agent in the storage cavity 14 is discharged quantitatively, and the problem of uneven dispersion of flocculating agent caused by excessive one-time addition, sudden local concentration, and flocculation failure is avoided. The first rotating shaft 7 drives the mounting cylinder 8 to rotate at the same time, so that the stirring rod 9 rotates to stir the wastewater and the flocculating agent, helping the wastewater and the flocculating agent to mix. After the wastewater and the flocculating agent are mixed, the rotating ring 33 moves up and down under the control of the second hydraulic cylinder 32, driving the scraper 34 to move up and down. The scraper 34 can scrape the flocculating material adhered to the inside of the tank body 1. When the scraper 34 moves downward, the stirring rod 9 moves downward and tightly contacts the bottom of the tank body 1. By controlling the rotation of the stirring rod 9, the flocculating material adhered to the bottom of the tank body 1 can be scraped. If the stirring rod 9 has flocculating material adhered thereto, the stirring rod 9 moves up and down in the wastewater under the control of the second hydraulic cylinder 32, increasing the shear force between the stirring rod 9 and the wastewater, so that the flocculating material adhered to the stirring rod 9 can be effectively cleaned. Subsequently, the scraper 34 and the stirring rod 9 are moved out of the wastewater under the control of the second hydraulic cylinder 32. The first rotating shaft 7 drives the extrusion plate 25 to rotate at the same time, so that the plurality of stirring blades 36 rotate to stir the mixed wastewater, so that the wastewater forms a vortex. Then the motor 6 is turned off, and the stirring blades 36 stop rotating. At this time, the centrifugal force of the wastewater disappears, and the flocculating material in the wastewater gradually moves to the center and falls into the discharge pipe 10, which is supported and accumulated by the supporting plate 11. If large flocculating material is deposited at the bottom of the tank body 1 and cannot be moved by the centrifugal force, the stirring rod 9 slowly moves upward under the control of the second hydraulic cylinder 32, driving the plurality of push plates 35 to slowly move upward. Subsequently, the plurality of push plates 35 quickly move downward under the control of the second hydraulic cylinder 32. The impact force formed by the arc surface at the bottom of the push plate 35 can push the large flocculating material at the bottom of the tank body 1 to move to the discharge pipe 10. The motor 6 moves downward under the control of the first hydraulic cylinder 4, driving the first rotating shaft 7 to move downward, so that the extrusion plate 25 moves downward and enters the discharge pipe 10 to block the discharge pipe 10. The flocculating material on the top of the supporting plate 11 is extruded by the extrusion plate 25. The extrusion plate 25 moves downward at the same time, compressing the second spring 37. With the downward extrusion of the extrusion plate 25,The filter plate 27 filters the flocculation, so that the waste water contained in the flocculation passes through the filter plate 27 into the cavity 26, and is discharged from the liquid discharge pipe 28 to the tank body 1 again through the one-way valve 29, thereby saving the discharge of waste water, and the waste water remaining in the tank body 1 can be recycled in subsequent use, and the remaining flocculation is left between the extrusion plate 25 and the supporting plate 11, and the bottom of the supporting plate 11 is supported by the first spring 30 cooperating with the clamping block 31, and the bottom of the supporting plate 11 abuts against the inclined surface at the top of the clamping block 31, and when the second spring 37 is pressed to the limit, the supporting plate 11 pushes the clamping block 31 to move and compresses the first spring 30, and the clamping block 31 loses the limiting position, and under the action of the second spring 37, the supporting plate 11 moves downward and moves out of the tank body 1, and the flocculation filtered along the inclined surface at the top of the supporting plate 11 falls, thereby helping to clean the flocculation in the tank body 1, and after the flocculation at the top of the supporting plate 11 is discharged, the first hydraulic cylinder 4 controls the motor 6 to move upward, so that the first rotating shaft 7 and the extrusion plate 25 move upward, driving the supporting plate 11 to move upward, and when the supporting plate 11 moves to the clamping block 31, it abuts against the inclined surface at the bottom of the clamping block 31, and in the same way, under the extrusion of the supporting plate 11, the clamping block 31 moves, facilitating the upward movement of the supporting plate 11 through the clamping block 31.
