A reagent stirring device for wastewater treatment includes: a stirring barrel 10, a stirring assembly 20 is arranged inside the stirring barrel 10, a filtering assembly 30 is arranged inside the stirring barrel 10 and at the top of the stirring assembly 20, and a storage assembly 40 is arranged on the left side of the stirring barrel 10;

[0025] The stirring assembly 20 includes a stirring rod 21 rotatably arranged inside the stirring barrel 10, a drive motor 22 for driving the stirring rod 21 to rotate is fixedly arranged at the bottom of the stirring barrel 10, a clear water discharge pipe 23 is communicated and arranged near the top on the right side of the stirring barrel 10, and a sludge discharge pipe 24 is communicated and arranged at the bottom of the clear water discharge pipe 23 on the right side of the stirring barrel 10;

[0026] During the process of using the device by the staff, external sewage is transported to the inside of the stirring barrel 10 through the feeding pipe 60 on the left side, and is filtered by the filter rack 31. The solid impurities in the sewage are filtered through the filter rack 31, and the filtered sewage falls to the bottom inside the stirring barrel 10. Chemical reagents for sewage treatment (chemical reagents for flocculation and precipitation) are input through the feeding pipe 60 on the right side. The driving motor 22 starts to work, driving the stirring rod 21 to rotate. The stirring rod 21 drives the first stirring member 25 and the second stirring member 26 to stir the chemical reagents and sewage in the stirring barrel 10. This not only improves the solid-liquid separation efficiency, but also speeds up the reaction rate by stirring the reagents and wastewater, thereby greatly improving the purification efficiency and having high reliability.

[0027] The filtering assembly 30 includes a filter rack 31 arranged inside the stirring barrel 10 and located at the top of the stirring rod 21. The bottom of the filter rack 31 is rotatably connected to the top of the stirring rod 21. A driven rod 32 is rotatably arranged at the top of the filter rack 31. A rotating rack 33 adapted to the filter rack 31 is fixedly installed at the top of the driven rod 32. Cleaning brushes 34 are fixedly installed on both the left and right sides of the driven rod 32 at the bottom of the rotating rack 33.

[0028] The stirring rod 21 drives the driven rod 32 to rotate, the driven rod 32 drives the rotating rack 33 to rotate, and the rotating rack 33 drives the cleaning brushes 34 to clean the surface of the filter rack 31. This can not only prevent impurities from blocking the filter rack 31 and affecting the filtering effect of the device, but also drive the solid impurities remaining on the top of the filter rack 31 to rotate and fall into the inside of the storage box 42 through the connecting pipe 35.

[0029] The storage assembly 40 includes a mounting rack 41 arranged on the left side of the stirring barrel 10. A storage box 42 is fixedly installed at the top of the mounting rack 41, and a filter plate 43 is fixedly installed inside. A water pump 44 is arranged at the top of the stirring barrel 10. A delivery pipe 45 is connected and arranged between the right side of the storage box 42, at the bottom of the filter plate 43 and the left side of the water pump 44.

[0030] The impurities falling into the storage box 42 land on the top of the filter plate 43. Since the top of the storage box 42 is open, it is convenient for the staff to clean in time. At the same time, the sewage following the impurities falls to the bottom inside the storage box 42 through the action of the filter plate 43. The water pump 44 starts to work, and the sewage at the bottom of the storage box 42 is re-transported to the inside of the stirring barrel 10 through the delivery pipe 45 to avoid waste.

[0031] A plurality of support legs are fixedly installed at the bottom of the stirring barrel 10. An observation window 50 is arranged near the right side at the front of the stirring barrel 10.

[0033] On both the left and right sides of the stirring rod 21, two first stirring members 25 are fixedly installed. On both the top and bottom of the first stirring member 25, a plurality of second stirring members 26 are fixedly installed. At the inner bottom of the stirring barrel 10 and on the outer edge of the stirring rod 21, a waterproof ring is provided.

[0034] The bottom of the driven rod 32 is fixedly connected to the top of the stirring rod 21. On the left side of the stirring barrel 10 and on the top of the mounting frame 41, a connecting pipe 35 is communicated and provided.

[0035] The top of the mounting frame 41 is open. The water outlet end at the bottom of the water pump 44 is fixedly installed with a water outlet pipe. The bottom end of the water outlet pipe penetrates through the top of the stirring barrel 10 and extends to the inside of the stirring barrel 10.

[0036] The working principle of the reagent stirring device for wastewater treatment provided by the present utility model is as follows:

[0037] The first step: During the process of use by the staff, external sewage is conveyed into the inside of the stirring barrel 10 through the feeding pipe 60 on the left side, and is filtered by the filtering frame 31. The solid impurities in the sewage are filtered through the filtering frame 31. The filtered sewage falls to the inner bottom of the stirring barrel 10. A chemical reagent for sewage treatment (a chemical reagent for flocculation precipitation) is put in through the feeding pipe 60 on the right side. The driving motor 22 starts to work, driving the stirring rod 21 to rotate. The stirring rod 21 drives the first stirring member 25 and the second stirring member 26 to stir the chemical reagent and sewage in the stirring barrel 10. This not only improves the solid-liquid separation efficiency, but also speeds up the reaction rate by stirring the reagent and wastewater, thereby improving the purification efficiency and having high reliability.

[0038] The second step: At the same time, the stirring rod 21 drives the driven rod 32 to rotate. The driven rod 32 drives the rotating frame 33 to rotate. The rotating frame 33 drives the cleaning brush 34 to clean the surface of the filtering frame 31. This can not only prevent impurities from blocking the filtering frame 31 and affecting the filtering effect of the device, but also drive the solid impurities remaining on the top of the filtering frame 31 to rotate and fall into the inside of the storage box 42 through the connecting pipe 35.

[0039] The third step: The impurities falling into the storage box 42 land on the top of the filter plate 43. Since the top of the storage box 42 is open, it is convenient for the staff to clean in time. At the same time, the sewage following the impurities falls to the inner bottom of the storage box 42 through the action of the filter plate 43. The water pump 44 starts to work, and the sewage at the bottom of the storage box 42 is re-conveyed into the inside of the stirring barrel 10 through the conveying pipe 45 to avoid waste.

[0040] Compared with the related technology, the reagent stirring device for wastewater treatment provided by the present utility model has the following

[0041] Beneficial effects:

[0042] Through the coordinated arrangement of the various components of the device, when the stirring assembly 20 stirs the chemical reagent and sewage, the stirring rod 21 drives the driven rod 32 to rotate, the driven rod 32 drives the rotating frame 33 to rotate, and the rotating frame 33 drives the cleaning brush 34 to clean the surface of the filter frame 31. This not only prevents impurities from clogging the filter frame 31 and affecting the filtering effect of the device, but also drives the solid impurities remaining on the top of the filter frame 31 to rotate and fall into the inner side of the storage box 42 through the connecting pipe 35. With the cooperation of the storage assembly 40, the filtered impurities fall to the bottom of the inner side of the storage box 42. At the same time, the water pump 44 re-transports the sewage at the bottom of the storage box 42 to the inside of the stirring barrel 10 through the delivery pipe 45, avoiding waste and greatly increasing the practicality of the device.
