[0030] In order to solve the technical problems in the background technology, such as Figure 1-4 As shown, this application provides a technical solution: a simple sewage filtration mechanism, which has the following characteristics:

[0031] This simple sewage filtration mechanism includes a screen separation tank 1 located upstream of the entire filtration mechanism. The screen separation tank 1 has a sewage inlet 2 and a solid waste outlet baffle 3. During normal operation, sewage enters the screen separation tank 1 through the sewage inlet 2. Larger solid waste, such as large vegetable leaves, fish bones, tree leaves, and plastic bags, is intercepted by the screen, thus separating them and achieving preliminary solid-liquid separation. A first sewage tank 4 is provided at the lower end of the screen separation tank 1 to receive the sewage after separation by the screen separation tank 1. Inside the first sewage tank 4, a rotating shaft 5 is provided, on which a number of blades 6 are evenly mounted. One end of the rotating shaft 5 is connected to a motor 7. When the motor 7 is activated and operated, it drives the rotating shaft 5 to rotate, which in turn drives the blades 6 to agitate the sewage, further settling suspended matter in the sewage. The rotation of the rotating shaft 5 and blades 6 impacts larger particles in the sewage, such as silt, stripping suspended matter from their surfaces. This also creates vortices within the first sewage tank 4, facilitating the separation of water and sludge of varying quality. The first sewage tank 4 is connected to the water pump 8, the first purification tank 9, and the second purification tank 10 in sequence via pipes. The main function of the water pump 8 is to pump water from the first sewage tank 4 and transport it to the first purification tank 9. Inside the first purification tank 9, a fiber filter 12 is installed, which effectively filters out larger suspended particles in the sewage. The water then flows into the second purification tank 10, where zeolite 13 is installed. This adsorbs harmful substances in the sewage, further purifying the water quality. Above the second sewage tank 11, a cone 14 is installed, on which an oil-water separator 15 is mounted. The oil-water separator 15 is a common technology in the field, and its specific structure is not described in detail. Because oil and water have different densities, oil has a lower density and therefore floats. The oil-water separator 15 can then separate the oil from the sewage and discharge it through the oil outlet 16. The design of the cone 14 helps improve separation efficiency. In addition, a first mud outlet 17 is provided at the bottom of the first sewage tank 4 for regularly discharging the sludge deposited at the bottom of the tank. A water outlet 18 is provided in the middle of the second sewage tank 11 for discharging the treated clean water.

[0032] It should be noted that the second mud discharge port 19 is provided at the bottom of the second sewage tank 11 for discharging the sludge in the tank. It is provided at the bottom of the second sewage tank 11, which is conducive to the smooth discharge of the sludge, avoids the sedimentation of the sludge in the tank, and improves the sewage treatment efficiency. The structure of the second mud discharge port 19 includes a circular or square opening. During the sewage treatment process, the sludge gradually accumulates in the second sewage tank 11. When the sludge accumulates to a certain extent, the operator opens the second mud discharge port 19, and the sludge is discharged through the second mud discharge port 19. A screw pump can be further provided at the second mud discharge port 19. The discharged sludge can be further dehydrated, harmlessly treated, etc.

[0033] It should be noted that a heater 20 is provided at the top of the second sewage tank 11. When there is oil in the sewage, it needs to be separated. Due to the different densities of oil and water, the oil will float. However, because the freezing point of oil is low, it tends to solidify at the top. Therefore, setting the heater 20 at the top is conducive to heating the oil. The heater 20 is fixed to the top of the second sewage tank 11 by bolts. The position diagram is shown in the figure below. Figure 1 The heating rod of the heater 20 extends into the second sewage pool 11 and contacts the liquid in the pool to ensure effective heat transfer. The setting of the heater 20 can effectively prevent the oil from solidifying during the oil-water separation process.

[0034] Furthermore, the rotating shaft 5 is positioned in the middle of the first sewage tank 4, so that the blades 6 can cover the entire cross-section of the sewage tank during stirring, thereby achieving uniform stirring of the sewage. After the motor 7 is started, the rotating shaft 5 drives the blades 6 to stir and rotate, promoting the separation of solid particles such as silt from the sewage.

[0035] It should be noted that the cone top 14 adopts a conical structure, and an oil-water separator 15 is provided on the top. As a part of the second sewage pool 11, the inclined surface of the cone top 14 helps the oil-water mixture to flow in the second sewage pool 11, reduces eddy currents, and improves the separation effect. The oil-water separator 15 is set at the highest point of the cone top 14, so that the oil-water mixture can be larger at the bottom and smaller at the top before entering the separator due to the structure of the cone top 14. The increasingly smaller top allows the oil phase and the water phase in the oil-water mixture to be separated to a certain extent, and the oil with lower density will float on it. The oil-water separator 15 is set at the highest point to improve the separation efficiency.

[0036] Furthermore, the solid waste outlet baffle 3 is movably connected to the grid separation tank 1 to facilitate the discharge of separated solid waste from the system. The solid waste outlet baffle 3 can be removed regularly to discharge the solid waste accumulated at the bottom of the grid separation tank 1 after separation.

[0037] It should be pointed out that during the stirring process, since the position of the blade 6 is set upward, the rotation of the blade 6 can effectively hit the mud and sand, and fully remove the suspended matter on its surface; on the other hand, it will not interfere with the mud and sand settled at the bottom of the pool, thereby improving the purification efficiency.

[0038] It should be noted that water pump 8 is connected to the middle of first sewage tank 4 via a connecting pipe. The primary function of water pump 8 is to extract sewage from first sewage tank 4 and transport it to subsequent treatment units via the connecting pipe. The connecting pipe opening is located in the middle of first sewage tank 4, specifically near the centerline of the tank. This design prevents water pump 8 from directly contacting sediment at the tank bottom when extracting sewage, effectively preventing sediment from being carried away and allowing it to naturally settle in the center of the tank bottom.

[0039] It should be noted that the sludge collecting hopper 21 is located at the lower end of the first sewage tank 4 and is connected to the first sewage tank 4. The sludge collecting hopper 21 has an inverted conical structure, characterized by being larger at the top and smaller at the bottom. Its upper end is connected to the first sewage tank 4. The specific structure of the sludge collecting hopper 21 is as follows: the diameter of the upper end of the sludge collecting hopper 21 is larger than the diameter of the lower end, forming a structure with a larger upper end and a smaller lower end. The wall surface of the sludge collecting hopper 21 is inclined, which facilitates the sedimentation and discharge of the sludge. The sludge collecting hopper 21 is equipped with a valve, and the sludge discharge rate can be controlled by adjusting the valve opening.

[0040] It should be noted that the first mud discharge port 17 is located in the middle of the bottom of the mud collection hopper 21. It is used to discharge mud. During operation, mud slowly enters the mud collection hopper 21 from the top. As the mud accumulates, when it reaches a certain height, the first mud discharge port 17 is intermittently opened, and the mud is automatically discharged through the first mud discharge port 17, thereby achieving mud discharge.

[0041] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
