Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency treatment device for low-pollution sewage. Background Art

[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original function is simply called sewage. It is mainly water used in life. It contains more organic matter and is easier to treat. Low-pollution sewage is a type of sewage. Although the concentration of major pollutants in low-pollution water is low, the total amount of emissions is large, so the pollution load is high and must be handled by relevant personnel.

[0003] The patent with the patent authorization announcement number CN220404944U discloses a sewage treatment tank, which relates to the field of sewage treatment tanks and includes a treatment tank body and a filter screen. The side wall of the filter screen is fixedly installed with a slider. The inner wall of the treatment tank body is provided with a slide groove for the slider. The inner wall of the treatment tank body is slidably connected to an insert block. The inner wall of the slider is provided with a slot for the insert block to be inserted. The inner wall of the slider is slidably connected to a push rod for pressing the insert block. Although the above patent can facilitate the removal and replacement of the filter screen and effectively improve the efficiency of replacing the filter screen, there are still some shortcomings in actual use. For example, when treating sewage, the sewage is simply filtered through the filter screen. This treatment method can only remove impurities such as foreign matter in the sewage and cannot deeply treat harmful substances in the sewage, resulting in poor sewage treatment effect.

[0004] Therefore, there is a particular need for a low-pollution sewage high-efficiency treatment device to solve the problems existing in the prior art. Utility Model Content

[0025] First, the staff connects the medicine delivery pipe to the liquid inlet 10 so that the medicine is continuously delivered to the medicine tank 9, and then turns on the motor 4 through the controller 23. Subsequently, the sewage delivery pipe and the discharge pipe are connected to the water inlet 2 and the water outlet 22 respectively, so that the sewage is delivered to the shell 1. The delivered sewage is filtered through the filter 3, and the filtered foreign matter and other impurities remain on the surface of the filter 3. During filtering, the baffle 17 blocks foreign matter and other impurities on the surface of the filter 3 to prevent foreign matter and other impurities from falling into the shell 1. The filtered sewage continues to flow into the shell 1. At the same time, the medicine in the medicine tank 9 flows out from the nozzle 11 to the shell 1 Mixed into the sewage, and then reacted with the sewage to perform deep treatment on it, so as to improve the treatment effect of the sewage. The output shaft of the motor 4 drives the stirring rod 5 to rotate, and then the stirring rod 5 stirs the sewage and the medicine, so that the two are fully mixed. When the stirring rod 5 rotates, the pulley assembly 6 drives the bidirectional screw Ⅰ7 to rotate, and then the medicine tank 9 moves to the left to the limit and then to the right to the limit.

The treated sewage flows into the sewage discharge pipe for discharge. When the bidirectional screw Ⅰ7 rotates, it drives the bidirectional screw Ⅱ13 to rotate through the bevel gear group 12. , and then the wedge plate 15 drives the brush 16 to move forward to the limit and then moves backward to the limit. When the brush 16 moves forward, it pushes the foreign matter and other impurities on the surface of the filter 3 forward. When the wedge plate 15 drives the brush 16 to move forward to the appropriate position, the wedge plate 15 contacts the baffle 17 in advance and squeezes it to move upward. (The lower part of the wedge plate 15 is provided with a sharp corner, and the lower part of the baffle 17 is provided with a rounded corner. Therefore, when the wedge plate 15 contacts the baffle 17, the sharp corner of the wedge plate 15 will squeeze into the rounded corner of the baffle 17 and lift it up, so that the wedge plate 15 squeezes the baffle 17 to move upward), and the spring 18 is compressed accordingly. At this time, the brush 16 will filter Foreign matter and other impurities on the surface of the mesh 3 are pushed into the collection box 20, thereby achieving the purpose of automatically cleaning the filter 3 and ensuring the filtration efficiency of the filter 3. When the wedge plate 15 drives the brush 16 to move backward, the wedge plate 15 is out of contact with the baffle 17, and the spring 18 returns to its original state, thereby causing the baffle 17 to move downward to continue to block foreign matter and other impurities on the filter 3. The wedge plate 15 drives the brush 16 to move back and forth, continuously pushing foreign matter and other impurities filtered out of the surface of the filter 3 into the collection box 20. When the sewage treatment is completed, the motor is turned off, and the sewage delivery pipe and discharge pipe are disconnected from the water inlet 2 and the water outlet 22 respectively.
