[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model embodiment provides a multi-stage filtration filter for wastewater treatment, such as... Figures 1-5 As shown, it includes a filter tank 1 and a support frame 4; the support frame 4 is fixed on both sides of the bottom end of the filter tank 1, the auxiliary structure 2 is provided on the top of the filter tank 1, the servo motor 5 is installed in the middle of the filter tank 1, the stirring shaft 6 is installed inside the filter tank 1, and the scraper 7 is installed on the outside of the stirring shaft 6.

[0024] The auxiliary structure 2 includes an extrusion box 202, which is installed at the top of the filter tank 1. An inlet 201 is installed on one side of the top of the extrusion box 202. A spiral blade 203 is installed inside the extrusion box 202. A collection box 204 is installed at the bottom of one side of the extrusion box 202. A filter port 205 is provided at the bottom of the extrusion box 202. Multiple sets of blades are provided on the outside of the spiral blade 203. The multiple sets of blades are arranged at equal intervals on the outside of the spiral blade 203.

[0025] In a further preferred embodiment of this utility model, such as Figures 1-5As shown: When treating wastewater, wastewater is first injected into the inlet 201. Then, the drive motor on one side of the inlet 201 is started to rotate the spiral shaft 203. When the spiral shaft 203 rotates, it will cause the wastewater to move inside the squeezing box 202. When the wastewater reaches the filter port 205, the screen inside the filter port 205 will screen the wastewater, removing larger impurities. The screened wastewater will then flow into the filter tank 1, and the screened impurities will be discharged into the collection box 204, thus completing the initial treatment of the wastewater.

[0026] A filter structure 3 is provided on one side of the bottom end of the filter tank 1. The filter structure 3 includes a sewage tank 305, which is installed on one side of the bottom end of the filter tank 1. A filter screen 301 is installed on the top of the sewage tank 305. A collection box 302 is installed on the top of one side of the sewage tank 305. An installation box 303 is installed on one side of the sewage tank 305. A filter plate 304 is installed inside the installation box 303. Multiple sets of filter plates 304 are arranged at equal intervals inside the installation box 303. The multiple sets of filter plates 304 and the installation box 303 form an insertion structure. Multiple sets of stirring rods are provided on the outside of the stirring shaft 6. The multiple sets of stirring rods are distributed in a ring on the outside of the stirring shaft 6. Two sets of scrapers 7 are provided. The two sets of scrapers 7 are symmetrically distributed on the outside of the stirring shaft 6.

[0027] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: When wastewater falls into the filter tank 1, flocculant is poured into the filter tank 1. To improve the flocculation effect, the servo motor 5 is started to drive the stirring shaft 6 to rotate and stir the wastewater, making the flocculation effect better. The scraper 7 is used to scrape the inner wall of the filter tank 1 to prevent impurities from sticking to the inner wall of the filter tank 1 and affecting the wastewater treatment. After the wastewater flocculation is completed, the wastewater is discharged. At this time, the filter screen 301 is used to filter the flocculated wastewater again. Since the filter screen 301 is set with an inclination, the filtered flocculent falls into the filter box collection box 302. The filtered wastewater flows into the wastewater tank 305 and then into the installation box 303. Through the use of multiple sets of filter plates 304, the material of the filter plates 304 is activated carbon, which can perform a final filtration of the wastewater, thereby completing the multi-stage filtration of wastewater and making the wastewater treatment effect better.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
