[0022] like Figure 1-Figure 7As shown, the utility model is a sewage treatment device with a quickly replaceable filtering structure, comprising a sewage treatment box 1, a filter screen 2 and a stirring assembly 3. A feeding hopper 9 is provided on the sewage treatment box 1. A filtering chamber 6, a sewage treatment chamber 7 and an impurity recovery chamber 8 are provided in the sewage treatment box 1. The filtering chamber 6 is cylindrical. The feeding hopper 9 is connected to the filtering chamber 6. The filtering chamber 6 and the sewage treatment chamber 7 are connected through a feed opening 10. A slot 12 is provided on the sewage treatment box 1. The filter screen 2 is inserted into the feed opening 10 through the slot 12. The filtering chamber 6 and the impurity recovery chamber 8 are connected through a feed opening 10. The closing opening 11 is connected, and the impurity recovery chamber 8 is connected with the outside world through the discharge port 13; the filter screen 2 is detachably arranged on the sewage treatment box 1 by a butterfly screw 14; a discharge pipe 24 is provided on the sewage treatment box 1, and the discharge pipe 24 is connected with the sewage treatment chamber 7, and a valve 25 is provided on the discharge pipe 24; a guide plate 26 is provided on the sewage treatment box 1, and the guide plate 26 is located at the discharge port 13, and a collecting box 27 is placed on the side of the sewage treatment box 1 close to the discharge port 13, and the collecting box 27 is located below the guide plate 26; a guide slope 28 is provided at the bottom of the impurity recovery chamber 8.

[0023] A rotating shaft 4 is rotatably provided in the filter chamber 6, and a paddle 5 is provided on the rotating shaft 4. The paddle 5 contacts the inner wall of the filter chamber 6 and is used to clean impurities on the filter screen 2. The paddle 5 is provided in several groups, and the several groups of paddles 5 are distributed in a ring array. The stirring component 3 is arranged in the sewage treatment chamber 7, and the stirring component 3 includes a stirring shaft 15 and a stirring blade 16. The stirring shaft 15 is rotatably provided in the sewage treatment chamber 7, and the stirring blade 16 is provided on the stirring shaft 15.

[0024] A motor 17 is provided on the sewage treatment tank 1, and a first pulley 18 is sleeved on the output shaft of the motor 17. One end of the rotating shaft 4 rotates and extends to the outside of the sewage treatment tank 1, and a second pulley 19 and a third pulley 21 are sleeved on the end of the rotating shaft 4 located outside the sewage treatment tank 1. A first transmission belt 20 is sleeved on the first pulley 18 and the second pulley 19. One end of the stirring shaft 15 rotates and extends to the outside of the sewage treatment tank 1, and a fourth pulley 22 is sleeved on the end of the stirring shaft 15 located outside the sewage treatment tank 1, and a second transmission belt 23 is sleeved on the third pulley 21 and the fourth pulley 22.

[0025] During specific use, the motor 17 is started, and the first pulley 18 is driven to rotate clockwise by the motor 17. The first pulley 18 drives the second pulley 19 to rotate through the first transmission belt 20. The second pulley 19 drives the rotating shaft 4 and the third pulley 21 to rotate. When the rotating shaft 4 rotates, it will drive the paddle 5 to rotate. The third pulley 21 will drive the fourth pulley 22 to rotate through the second transmission belt 23. The fourth pulley 22 drives the stirring shaft 15 to rotate, and the stirring shaft 15 is driven to rotate.

[0026] When sewage treatment is required, sewage and sewage treatment agent are first added into the filter chamber 6 through the feeding hopper 9. As the dial plate 5 rotates clockwise, the sewage and sewage treatment agent will be sent to the discharge port 10 at the bottom of the filter chamber 6. Then, the impurities mixed in the sewage and sewage treatment agent can be filtered through the filter screen 2 at the discharge port 10, so that the liquid passes through the filter screen 2 and falls into the sewage treatment chamber 7, while the solid impurities are left on the filter screen 2. The solid impurities on the filter screen 2 are sent to the recovery port 11 through the continuous clockwise rotation of the dial plate 5, and the solid impurities enter the impurity recovery chamber 8 through the recovery port 11. The solid impurities entering the impurity recovery chamber 8 will slide along the guide slope 28 and finally be discharged from the discharge port 13. Under the guidance of the guide plate 26, the solid impurities will fall into the collection box 27 for collection. The liquid entering the sewage treatment chamber 7 is fully stirred and mixed under the rotation of the stirring blade 16, so that the sewage and the sewage treatment agent can be mixed and reacted more evenly, thereby improving the reaction efficiency. When the filter screen 2 needs to be replaced, it is only necessary to remove the butterfly screw 14 first, and then the filter screen 2 can be pulled out from the sewage treatment tank 1 for replacement, which is simpler and more convenient to operate.

[0027] In summary, in this solution, the motor 17 can simultaneously drive the rotating shaft 4 and the stirring shaft 15 to rotate. The rotating shaft 4 can drive the paddle 5 to rotate to clean the impurities on the filter 2, thereby preventing the filter 2 from being blocked and affecting the filtering efficiency. The stirring shaft 15 can drive the stirring blade 16 to rotate to mix and stir the sewage and the sewage treatment agent so that they can fully mix and react. The filter 2 is installed by plugging in, which makes the installation method simpler. At the same time, the filter 2 is replaced by the butterfly screw 14, which makes it easier to replace the filter 2.
