[0024] Reference Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the utility model:

[0025] A sewage pretreatment device comprises a first sewage pool 3, a second sewage pool 10 is arranged at the right part of the first sewage pool 3, a sludge funnel 9 is fixedly connected to the lower parts of the first sewage pool 3 and the second sewage pool 10, an inclined tube sedimentation tank 4 is arranged at the right part of the second sewage pool 10, a fan 19 is arranged at the rear parts of the first sewage pool 3 and the second sewage pool 10, a connecting pipe 20 is fixedly connected to the output end of the fan 19, the connecting pipe 20 is fixedly connected to the inside of the first sewage pool 3 and the second sewage pool 10, an air duct 21 is fixedly connected to the inside of the first sewage pool 3 and the second sewage pool 10, and an anti-blocking component is arranged at the upper part of the first sewage pool 3;

[0026] The sewage enters the first sewage pool 3 with a sludge funnel 9 for primary treatment. The sludge funnel 9 can help precipitate suspended solid particles in the sewage and gather them at the bottom of the funnel. The first sewage pool 3 and the second sewage pool 10 are provided with wind chambers. By starting the fan 19, the fan 19 ventilates the wind chamber inside the first sewage pool 3 through the connecting pipe 20, and then blows it out through the air duct 21 to stir the sewage in the pool to form a vortex. At the same time, aeration is performed to provide oxygen. Then the sewage enters the second sewage pool 10, and the operation is repeated for secondary treatment to settle the inorganic matter in the floc and part of the SS attached. Under the action of rotation and aeration, part of the inorganic matter and the SS attached to the organic floc will gradually settle to the bottom of the pool. Then the sewage enters the inclined tube sedimentation tank 4 through the central guide tube 22. The sewage after preliminary treatment enters the inclined tube sedimentation tank 4. The principle of the inclined tube is used to make the sedimentation speed faster, which helps to further separate the suspended matter in the water.

[0027] Reference Figure 1 and Figure 2 The anti-blocking component includes a fixed cylinder 2, which is fixedly connected to the upper part of the first sewage pool 3, and the left part of the fixed cylinder 2 is fixedly connected to the water inlet pipe 1. An extrusion disk 11 is arranged inside the fixed cylinder 2, and an extrusion column 23 is fixedly connected to the upper part of the extrusion disk 11. A slide groove 13 is provided inside the extrusion column 23, and a limit plate 12 is fixedly connected to the upper side of the fixed cylinder 2. Both sides of the upper part of the extrusion column 23 are fixedly connected with telescopic springs 15, and the telescopic spring 15 is fixedly connected to the lower part of the limit plate 12. A slot 18 is provided on the right side of the interior of the fixed cylinder 2, and a slide rod 17 is arranged on the right side of the interior of the fixed cylinder 2. The slide rod 17 is fixedly connected to the inside of the slot 18, and a slider 16 is slidably connected to the outside of the slide rod 17. The slider 16 is fixedly connected to the right part of the extrusion disk 11, and the upper part of the extrusion column 23 is fixedly connected to the fixed plate 14;

[0028] When it is necessary to unload the fixed cylinder 2 to prevent clogging, the fixed plate 14 is pulled so that the fixed plate 14 drives the extrusion column 23 to slide, and the extrusion column 23 drives the extrusion plate 11 to slide, and at the same time, the extrusion plate 11 drives the slider 16 to slide on the outer wall of the slide rod 17, so that the extrusion column 23 slides stably in the fixed cylinder 2. The extrusion column 23 slides in the limit plate 12, which increases the convenience of using the device, thereby saving a lot of time and energy, and improving the safety of using the device, making it convenient for people to unload the device quickly. When sewage enters the fixed cylinder 2 through the water inlet pipe 1, the fixed plate 14 is loosened, so that the extrusion plate 11 is reset by the telescopic spring 15, so that the extrusion plate 11 squeezes the inside of the fixed cylinder 2, thereby facilitating unloading and preventing clogging of the fixed cylinder 2.

[0029] Reference Figure 1 , Figure 2 and Figure 4The four corners of the bottom of the first sewage tank 3, the second sewage tank 10 and the inclined tube sedimentation tank 4 are fixedly connected with brackets 7, the right part of the inclined tube sedimentation tank 4 is fixedly connected with a water outlet pipe 5, the bottoms of the first sewage tank 3, the second sewage tank 10 and the inclined tube sedimentation tank 4 are connected through a central guide tube 22, the extrusion plate 11 is slidably connected to the inside of the fixed tube 2, the extrusion column 23 is slidably connected to the inside of the limit plate 12, and the bottom of the inclined tube sedimentation tank 4 is fixedly connected with a sewage pipe 6, and a valve 8 is arranged outside the sewage pipe 6;

[0030] The first sewage pool 3, the second sewage pool 10 and the inclined tube sedimentation tank 4 are supported by arranging a bracket 7, the treated sewage is discharged by arranging a water outlet pipe 5, and the sewage after sedimentation treatment is transported by arranging a central guide tube 22. The extrusion plate 11 slides inside the fixed tube 2 to prevent the fixed tube 2 from being blocked during material discharge. The extrusion column 23 slides inside the limit plate 12 to enable the extrusion plate 11 to squeeze the inside of the fixed tube 2, thereby facilitating the fixed tube 2 from being blocked during material discharge. The inorganic matter in the pool and the SS attached to the organic floccules are discharged from the sewage discharge pipe 6 by arranging to open the valve 8.

[0031] Working principle: When using this device, sewage enters the fixed cylinder 2 through the water inlet pipe 1, and enters the first sewage pool 3 with a sludge funnel 9 from the fixed cylinder 2 for primary treatment. The sludge funnel 9 can help precipitate the suspended solid particles in the sewage and gather them at the bottom of the funnel. By starting the fan 19, the fan 19 ventilates the wind cavity inside the first sewage pool 3 through the connecting pipe 20, and then blows it out through the air duct 21, stirring the sewage in the pool to form a vortex, and aerating to provide oxygen at the same time, and then the sewage enters the second sewage pool 10, and the operation is repeated for secondary treatment, so that the inorganic matter in the floccules and part of the SS attached to it will settle. Under the action of rotation and aeration, part of the inorganic matter and the SS attached to the organic floccules will gradually settle to the bottom of the pool, and then the sewage enters through the central guide cylinder 22 In the inclined tube sedimentation tank 4, the sewage after preliminary treatment enters the inclined tube sedimentation tank 4. The principle of the inclined tube is used to make the sedimentation speed faster, which is helpful to further separate the suspended matter in the water. Finally, the sludge formed at the bottom of each tank is discharged through the sewage pipe 6, and the sewage is discharged through the outlet pipe 5. When it is necessary to discharge the fixed cylinder 2 to prevent blockage, the fixed plate 14 is pulled to make the fixed plate 14 drive the extrusion column 23 to slide, so that the extrusion column 23 drives the extrusion plate 11 to slide, so that the extrusion plate 11 drives the slider 16 to slide on the outer wall of the slide rod 17. When the sewage enters the interior of the fixed cylinder 2 through the water inlet pipe 1, the fixed plate 14 is loosened, so that the extrusion plate 11 is reset by the telescopic spring 15, so that the extrusion plate 11 squeezes the interior of the fixed cylinder 2, thereby facilitating the discharge of the fixed cylinder 2 to prevent blockage.
