[0001] This utility model relates to the field of integrated domestic sewage treatment technology, specifically a high-efficiency urban sewage filtration and treatment device. Background Technology
[0002] Wastewater treatment is an important aspect of environmental protection, benefiting both present and future generations. Ensuring the safe, stable, normal, and compliant operation and management of wastewater treatment is crucial. Urban wastewater treatment plants are key infrastructure for urban development, and their operational status directly impacts urban water quality and sustainable social development. Comprehensive wastewater treatment refers to multi-stage treatment of domestic sewage to ensure it meets environmental standards and protects the environment and human health. Urban domestic sewage mainly includes daily washing wastewater and fecal sewage, containing a large number of bacteria and pathogens. Direct discharge without treatment will pollute the air, soil, and water bodies, leading to the development of urban wastewater filtration and treatment devices.
[0003] In the prior art, patent publication number CN205188064U discloses a comprehensive domestic sewage treatment device, including a sewage fermentation unit located at the top and a sewage filtration unit located at the bottom. The sewage fermentation unit includes a hydrolysis tank body, an inlet on the upper side and an outlet on the lower side of the hydrolysis tank body, and an air outlet on the upper side of the hydrolysis tank body. It also includes a stirring shaft, one end of which is connected to a drive motor located at the top of the hydrolysis tank body, and the other end extends into the hydrolysis tank body. The stirring shaft is equipped with triangular stirring blades and a heating resistance wire. A polyurethane insulation layer is provided on the inner wall of the hydrolysis tank body, and an anti-corrosion layer is coated on the surface of the polyurethane insulation layer.
[0004] The current type of domestic sewage filtration and treatment device has the following disadvantages: the stirring shaft driven by the motor drives the triangular stirring blades to stir the sewage after adding flocculant. The movement trajectory is fixed, and the mixing efficiency of flocculant and sewage is poor. Therefore, we propose a high-efficiency urban sewage filtration and treatment device. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a high-efficiency urban sewage filtration and treatment device.

The stirring plate is slidably connected inside the chute. A connecting rod is set between two vertically adjacent stirring plates. A slider is set at the upper end of the connecting rod. The top wall of the primary filtration tank has a circular chute. The slider is slidably connected inside the circular chute. By sliding up and down along the chute during the stirring of the wastewater, the stirring trajectory of the stirring plate is expanded, making the mixing efficiency of flocculant and wastewater higher.
[0008] Furthermore, a control switch is provided on the front side of the primary filtration tank, and the input terminal of the control switch is electrically connected to an external power source to control electrical appliances.

[0010] Furthermore, an inlet pipe is provided at the upper left side of the sewage treatment chamber, and an outlet pipe is provided at the lower right side of the sewage treatment chamber. A butterfly valve is connected in series in the middle of the outlet pipe to inject and discharge sewage into the sewage treatment chamber.
[0011] Furthermore, a filter cake hopper is inserted into slot one on the left side of the wastewater treatment chamber, and a fiber adhesive plate is inserted into slot two at the lower end of the filter cake hopper to filter out larger pollutants and grease in the wastewater.
[0012] Furthermore, a sludge suction pipe is installed at the lower front end of the wastewater treatment chamber to suck out the sediment.

Detailed Implementation
[0024] 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.
[0025] Please see Figure 1-7This embodiment provides a technical solution: a high-efficiency urban sewage filtration and treatment device, including a sewage treatment chamber 1, a primary filtration tank 14 on the left side of the sewage treatment chamber 1, a secondary filtration tank 13 on the right side of the sewage treatment chamber 1, an opening 12 on the left side of the secondary filtration tank 13, and a honeycomb plate 11 (the honeycomb plate 11 is composed of multiple inclined tubes and has a honeycomb-like appearance) on the right side of the secondary filtration tank 13. It also includes a mixing mechanism 7, and a control switch is provided on the front side of the primary filtration tank 14. Switch 6, the input terminal of control switch 6 is electrically connected to an external power source. An inlet pipe 2 is installed at the upper left side of the sewage treatment chamber 1, and an outlet pipe 8 is installed at the lower right side of the sewage treatment chamber 1. A butterfly valve is connected in series in the middle of the outlet pipe 8. A filter cake hopper 4 is inserted into slot one on the left side of the sewage treatment chamber 1, and a fiberboard 3 is inserted into slot two at the lower end of the filter cake hopper 4. A sludge suction pipe 5 is installed at the lower front side of the sewage treatment chamber 1 (the front side of the sludge suction pipe 5 is connected to the external suction pump). The front and rear side walls of the secondary filtration tank 13... An activated carbon filter plate 9 is installed on the left side of the secondary filtration tank 13, and a microfiltration plate 10 is installed on the right side between the front and rear side walls of the secondary filtration tank 13. Then, sewage is injected into the primary filtration tank 14 of the sewage treatment chamber 1 through the inlet pipe 2. At this time, the sewage will enter the sewage treatment chamber 1 through the inlet pipe 2, and then pass through the filter sludge hopper 4. The filter sludge hopper 4 will filter out the larger pollutants in the sewage. Then, it will pass through the fiber adhesive plate 3, which will adsorb the oil in the sewage. During the stirring process, sewage can be continuously added into the primary filtration tank 14. As the water level rises, the sewage will pass through the honeycomb plate 11 and settle. The settled sewage will flow into the secondary filtration tank 13 through the outlet 12. After the sewage flows into the secondary filtration tank 13, it will be adsorbed and filtered by the activated carbon filter plate 9 and the microfiltration plate 10, and finally reach the level of reusability. When too much sediment accumulates in the through holes of the honeycomb plate 11, the sediment will fall off under its own gravity and finally fall into the bottom of the primary filtration tank 14. The sediment will be extracted from the sludge suction pipe 5 by an external suction pump.
[0026] Mixing mechanism 7 includes a rotating rod 71, a sliding groove 72, a stirring plate 73, a connecting rod 74, a slider 75, and a circular groove 76. The rotating rod 71 is rotatably connected to a rotating hole in the top wall of the primary filtration tank 14. Two sets of symmetrical sliding grooves 72 are formed on the outer surface of the rotating rod 71. A stirring plate 73 is slidably connected inside each sliding groove 72. A connecting rod 74 is positioned between two vertically adjacent stirring plates 73. A slider 75 is positioned at the upper end of each connecting rod 74. A circular groove 76 is formed in the top wall of the primary filtration tank 14, and the sliders 75 are slidably connected inside the circular groove 76. The mixing mechanism 7 also includes a motor 77, which is installed in a mounting slot in the middle of the wastewater treatment chamber 1. The lower end of the output shaft of the motor 77 is fixedly connected to the upper end of the rotating rod 71. The input terminal of motor 77 is electrically connected to the output terminal of control switch 6. When the sewage treatment chamber 1 is filled with sewage, motor 77 is turned on by control switch 6. Motor 77 drives the rotating rod 71 to rotate, which drives the stirring plate 73 and the transmission link 74 to drive the slider 75 to slide inside the circular groove 76. Since the circular groove 76 is a stepped circular groove with one side higher than the other, if the slider 75 slides to the higher side of the circular groove 76, it will drive the link 74 to pull the stirring plate 73 to slide upward along the groove 72, thereby changing the movement trajectory of the stirring plate 73 and increasing the stirring range. By the stirring plate 73 sliding up and down along the groove 72 during the stirring of sewage, the stirring trajectory of the stirring plate 73 is expanded, making the mixing efficiency of flocculant and sewage higher.
[0027] The working principle of the high-efficiency urban sewage filtration and treatment device provided by this utility model is as follows: When treating urban domestic sewage, an appropriate amount of flocculant needs to be added to the sewage to be treated. Then, the sewage is poured into the primary filtration tank 14 of the sewage treatment chamber 1 through the inlet pipe 2. At this time, the sewage will enter the sewage treatment chamber 1 from the inlet pipe 2, and then pass through the filter sludge hopper 4. The filter sludge hopper 4 will filter out the larger pollutants in the sewage. Then, it passes through the fiber adhesive plate 3, which adsorbs the grease in the sewage. When the sewage treatment chamber 1 is full, the motor 77 is turned on by the control switch 6. The motor 77 drives the rotating rod 71 to rotate, which drives the stirring plate 73 and the transmission connecting rod 74 to drive the slider 75 to slide inside the circular groove 76. Since the circular groove 76 is a stepped circular groove with one side higher than the other, therefore... During the sliding process of slider 75, if it slides to the higher side of the circular groove 76, it will drive the connecting rod 74 to pull the stirring plate 73 to slide upward along the groove 72, thereby changing the movement trajectory of the stirring plate 73 and increasing the stirring range. During the stirring process, sewage can be continuously added into the primary filtration tank 14. As the water level rises, the sewage will pass through the honeycomb plate 11 and settle, so that the settled sewage flows into the secondary filtration tank 13 through the outlet 12. After the sewage flows into the secondary filtration tank 13, it will be adsorbed and filtered by the activated carbon filter plate 9 and the microfiltration plate 10, and finally reach the level of reusability. When too much sediment accumulates in the through holes of the honeycomb plate 11, the sediment will fall off under its own gravity and eventually fall into the bottom of the primary filtration tank 14. The sediment is then extracted from the sludge suction pipe 5 by an external suction pump.
[0028] It is worth noting that the motor 77 disclosed in the above embodiments can be a CDDR, and the control switch group 6 is provided with a button corresponding to the motor 77 and controlling its switching.
