[0027] See also Figure 1-4The utility model provides a technical solution: an industrial wastewater sedimentation treatment device, including a shell 1 and a motor 5. A stirring mechanism is arranged inside the shell 1, and the stirring mechanism includes a first through hole 2. The first through hole 2 is opened at the center of the bottom of the shell 1. A rotating shaft 4 is rotatably installed on the inner side of the first through hole 2 through a sealed bearing 3. The outer wall of the rotating shaft 4 is located inside the shell 1 and a stirring plate 7 is fixed thereon. Holes 8 are evenly opened on the stirring plate 7. The lower end of the rotating shaft 4 is fixedly connected to the output end at the top of the motor 5. The outer wall of the motor 5 is fixed to the bottom of the shell 1 through a fixing frame 6. By starting the motor 5, the stirring plate 7 can be driven to rotate, so that the stirring plate 7 can stir the flocculant and wastewater inside the shell 1, thereby improving the adsorption efficiency of the flocculant on the fixed particles in the wastewater.

[0028] A solid-liquid separation mechanism is arranged on the outer side of the stirring plate 7. The solid-liquid separation mechanism comprises a circular plate 10. A through groove 9 is arranged inside the circular plate 10. The end of the stirring plate 7 passes through the interior of the through groove 9. It is only necessary to take out the circular plate 10 and the filter screen 12 from the interior of the shell 1, so as to avoid the objects removed from the shell 1 being too heavy, thereby facilitating the workers to take out the filter screen 12 from the interior of the shell 1 for cleaning. A collecting groove 11 is arranged on the circular plate 10. A filter screen 12 is fixed to the bottom of the collecting groove 11. The collecting groove 11 opens upward, so as to ensure that when the collecting groove 11 moves upward, the solid impurities inside the collecting groove 11 will not fall into the interior of the shell 1, thereby ensuring the cleanliness of the industrial wastewater filtration. A handle 13 is fixed on the top of the filter screen 12, and the handle 13 and the stirring plate 13 are connected to each other. The mixing plates 7 are connected by a fixing mechanism, the handle 13 is designed as a "U"-shaped structure, and two handles 13 are symmetrically distributed about the central axis of the rotating shaft 4, the outer wall of the stirring plate 7 and the inner wall of the through groove 9 are in contact with each other, and the circular plate 10 forms a sliding structure with the stirring plate 7 through the through groove 9, and the stirring plate 7 and the through groove 9 are both distributed at equal angles with respect to the central axis of the circular plate 10. There are four collecting grooves 11 and four filter screens 12 distributed at equal angles with respect to the central axis of the circular plate 10, which increases the wastewater filtration area, and the circular plate 10, the collecting groove 11 and the filter screen 12 are conveniently lifted out of the inside of the shell 1 by the handle 13, and under the action of the filter screen 12, the solid-liquid separation inside the shell 1 can be completed, thereby facilitating the filtration of solid impurities in the wastewater.

[0029] The fixing mechanism includes a second through hole 14. A second through hole 14 is opened at the center of the top of the handle 13. A screw 15 is slidably installed inside the second through hole 14. The lower end of the screw 15 is threadedly installed inside the thread groove 16. The thread groove 16 is opened at the center of the top of the stirring plate 7. The outer wall of the screw 15 is located above the handle 13 and a screw plate 17 is fixed thereon. Two screw plates 17 are provided, and the screw plates 17 are symmetrically distributed about the central axis of the screw 15. The screw plates 17 facilitate the rotation of the screw 15, so that the screw 15 can be fixed on the thread groove 16, so that the positions of the circular plate 10 and the handle 13 can also be fixed, which is beneficial for the circular plate 10 to rotate with the stirring plate 7.

[0030] A drain pipe 18 is installed on one side of the shell 1 , and a valve 19 is provided on the drain pipe 18 , through which the filtered waste water inside the shell 1 can be discharged.

[0031] A support block 20 is installed at the bottom of the housing 1 , and the housing 1 can be supported by the support block 20 , so that the motor 5 can be installed at the bottom of the housing 1 .

[0032] Working principle: When using the industrial wastewater sedimentation treatment device, first add an appropriate amount of industrial wastewater and flocculant into the interior of the housing 1, then start the motor 5, at which time the motor 5 drives the stirring plate 7 to rotate through the rotating shaft 4, thereby accelerating the mixing speed of the industrial wastewater and the flocculant and improving the adsorption efficiency of the flocculant on the fixed particles in the wastewater;

[0033] After a period of time, solid impurities adsorbed together appear in the industrial wastewater. When it is necessary to filter out the fixed impurities in the wastewater, the screw 15 is rotated by screwing the plate 17. Since the screw 15 and the thread groove 16 are threadedly connected, the screw 15 and the thread groove 16 are separated, and then the through groove 9, the circular plate 10, the collecting groove 11 and the filter screen 12 are lifted upward by two U-shaped handles 13. Under the action of the filter screen 12, the solid impurities are collected in the inside of the collecting groove 11, thereby facilitating the filtration of solid impurities in the industrial wastewater and facilitating the removal of the filter screen 12 from the inside of the shell 1 for cleaning.
