DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 , a sewage treatment device for engineering construction in this embodiment includes a treatment tank 1. A driving motor 4 is arranged on the upper part of the treatment tank 1. The output end direction of the driving motor 4 is downward. The output end of the driving motor 4 is fixedly connected with a rotating shaft 5. A stirring block 6 is fixedly connected to the outside of the rotating shaft 5. A cleaning structure 9 is arranged on the rotating shaft 5.

[0023] Among them, the number of the stirring blocks 6 is several and they are symmetrically distributed on the outside of the rotating shaft 5.

[0024] The cleaning structure 9 includes a cleaning plate 901, a cleaning brush 902, a sliding block 904, a movable rod 905, a fixed rod 906, a limiting frame 907 and a return spring 908. The cleaning brush 902 is fixedly connected to the lower end of the cleaning plate 901. Both the cleaning plate 901 and the cleaning brush 902 are hinged to the side of the rotating shaft 5. The sliding block 904 slides in the cleaning plate 901. The movable rod 905 is hinged to the sliding block 904. The fixed rod 906 is fixedly connected to the outside of the rotating shaft 5. The limiting frame 907 is fixedly connected to the fixed rod 906 and the rotating shaft 5. The return spring 908 is sleeved on the outside of the movable rod 905.

[0025] Among them, the cleaning brush 902 is a brush specifically used for cleaning the filter screen.

[0026] It should be noted that the cleaning brush for cleaning the filter screen is a cleaning tool specifically used for cleaning fine pores such as filter screens, heat dissipation screens, air conditioner screens, and range hood filter screens. Such brushes usually have the following characteristics:

[0027] Bristle material: The bristles of the cleaning brush are usually made of soft but tough materials such as nylon and polyester fiber to avoid damaging the surface of the filter screen during the cleaning process.

[0028] Bristle shape: The bristles of the cleaning brush may be designed in different shapes such as round, long strip, spiral, etc. to better adapt to different types of filter screens.

[0029] It can be understood that by arranging a cleaning structure 9 inside the processing tank 1, when the rotating shaft 5 rotates, it can drive the cleaning plate 901 and the cleaning brush 902 to clean the first filter screen 7 or the second filter screen 8. When materials adhere to the inner wall of the processing tank 1, after the cleaning plate 901 comes into contact with the materials, the movable rod 905 cooperates with the sliding block 904 to slide in the sliding groove 903 of the cleaning plate 901. When the movable rod 905 displaces, it can cooperate with the return spring 908 to penetrate into the limiting frame 907, enabling the cleaning plate 901 to reduce its contact with the processing tank, so that the cleaning plate 901 and the cleaning brush 902 can perform elastic cleaning, thereby enhancing the practicality of the sewage treatment device and other advantages.

[0030] In this embodiment, a sliding groove 903 is formed inside the cleaning plate 901, and the sliding block 904 slides inside the cleaning plate 901 through the sliding groove 903.

[0031] In this embodiment, a through hole 909 is formed inside the fixed rod 906, and the movable rod 905 penetrates through the fixed rod 906 through the through hole 909.

[0032] In this embodiment, two water inlet pipes 2 are connected to the side of the processing tank 1.

[0033] In this embodiment, a water outlet pipe 3 is connected to the lower end of the processing tank 1, and a control valve is arranged inside the water outlet pipe 3.

[0034] In this embodiment, a first filter screen 7 is arranged on the inner wall of the processing tank 1, and a second filter screen 8 is arranged on the inner wall of the processing tank 1 below the first filter screen 7.

[0035] Among them, the filtering effect of double-filtering the sewage through the first filter screen 7 and the second filter screen 8 is better.

[0036] In this embodiment, the structures in the cleaning structure 9 are all symmetrically distributed based on the processing tank 1, and the number of cleaning brushes 902 is eight.

[0037] The working principle of the above embodiment is as follows:

[0038] First, the sewage is discharged into the processing tank 1 through the water inlet pipe 2, and the treated sewage is discharged from the processing tank 1 through the water outlet pipe 3.

[0039] Secondly, the driving motor 4 operates to drive the rotating shaft 5 to rotate, and the rotating shaft 5 drives the stirring block 6 to stir the sewage, so that the efficiency of the sewage passing through the first filter screen 7 or the second filter screen 8 is higher.

[0040] Finally, by providing a cleaning structure 9 inside the processing tank 1, when the rotating shaft 5 rotates, it can drive the cleaning plate 901 and the cleaning brush 902 to clean the first filter screen 7 or the second filter screen 8. When materials adhere to the inner wall of the processing tank 1, after the cleaning plate 901 comes into contact with the materials, the movable rod 905 cooperates with the sliding block 904 to slide in the sliding groove 903 of the cleaning plate 901. When the movable rod 905 displaces, it can cooperate with the return spring 908 to penetrate into the limiting frame 907, enabling the cleaning plate 901 to reduce its contact with the processing tank, so that the cleaning plate 901 and the cleaning brush 902 can perform elastic cleaning, thereby enhancing the practicality of the sewage treatment device and other advantages.

[0041] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the said element.
