The implementation principle of the preliminary impurity removal and purification equipment for sewage in the embodiment of the application is as follows: when the solid garbage in the sewage needs to be cleaned, the grating machine 3 is started, the rotary conveyor belt 32 starts to operate to drive the rake teeth 33 to start to do rotary motion, the rake teeth 33 fish the solid garbage in the sewage out of the sewage in the motion process and drive the garbage to be transported upwards, after the tines 33 have traveled to the highest point, the tines 33 are tilted by the carousel 32, so that the garbage on the rake teeth 33 falls into the garbage collecting plate 64 by gravity, the rake teeth 33 moving downward pass through the chute 511 of the flexible member 51, when the rake teeth 33 abut against the side wall of the flexible member 51, the solid waste wound around the rake teeth 33 cannot pass through the chute 511 of the flexible member 51, by the clamping of the flexible member 51, the garbage wound around the rake teeth 33 is torn out to the side of the flexible member 51 away from the grating machine 3 and falls into the garbage collecting plate 64, and falls into the garbage collecting tank 11 through the garbage collecting plate 64. The condition that the efficiency of the rake teeth 33 for fishing up the solid waste from the sewage is influenced by winding the waste on the rake teeth 33 is favorably reduced, and the rake teeth 33 are favorably kept in a clean state, so that the rake teeth 33 can better fish up the solid waste, the grid machine 3 can better separate the solid waste in the sewage, and the solid waste is not easy to flow into subsequent sewage treatment equipment to cause the fault and the damage of the sewage treatment equipment.

Through the arrangement of the sliding rod 42 slidably connected in the sleeve 41, the flexible part 51 can slide towards the direction close to the grille machine 3 and towards the direction far away from the grille machine 3, which is beneficial to reducing the situation that the operation space of the flexible part 51 arranged under the grille machine 2 is compact, and when the flexible part 51 needs to be replaced, the flexible part 51 is beneficial to being replaced more conveniently by making the flexible part 51 far away from the grille machine 2 to obtain larger operation space.

Through the setting of brush 68, because flexible piece 51 is when the rubbish on the clearance rake teeth 33, some rubbish can block in the spout 511 of flexible piece 51, when follow-up rake teeth 33 passed flexible piece 51, can take the rubbish of block in spout 511 out, the rubbish of taking out may fall outside the rubbish collection board 64, cause the pollution easily, through set up brush 68 on rubbish collection board 64, make the rubbish of taking out can be blockked by brush 68 and fall into on rubbish collection board 64, be favorable to reducing because of the rubbish that is taken out spout 511 by rake teeth 33 falls outside the rubbish collection board 64 and causes the condition of secondary pollution.

By providing the first base 52 to be removably attached to the beam 44, only the cleaning assembly 5 need be replaced when the flexible member 51 is worn to be replaced, rather than replacing an entire first rack 4.

The second base 682 is detachably connected to the garbage collecting plate 64, so that when the brush 68 is worn and needs to be replaced, only the brush 68 needs to be replaced, and the whole garbage collecting plate 64 does not need to be replaced, which is beneficial to saving resources.

Through the setting of flat mouth air gun 53 for solid waste that is cleared up by flexible member 51 can be blown to the rubbish collecting plate 64 on, is favorable to reducing because of rubbish gathers on flexible member 51 and leads to the condition of the rubbish on the flexible member 51 can't clear up rake teeth 33 better.

Through the setting that refuse collection board 64 has baffle 65 along width direction's both ends an organic whole for refuse collection board 64 is difficult to fall out when on refuse collection board 64 from the rubbish that drops on rake teeth 33 and the rubbish of clearing up out through flexible piece 51, is favorable to reducing the condition that causes secondary pollution because of rubbish falls out refuse collection board 64.

And is inclined toward one end of the waste collection tank 11 by a waste collection plate 64. The garbage on the garbage plate can be easily scratched into the garbage collection tank 11, the garbage accumulation on the garbage plate 64 can be reduced, and the garbage can smoothly enter the garbage collection tank 11 through the garbage plate 64.

Through the arrangement of the vibrator 66 fixedly connected to the baffle 65, the garbage on the garbage collecting plate 64 can enter the garbage collecting tank 11 more smoothly through the vibration of the vibrator 66.

The buffer member 63 is provided to reduce the loosening of the connection between the second bracket 6 and the garbage collecting plate 64 caused by the vibration of the vibrator 66.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
