[0018] The following is combined with Figure 1 - Figure 3This application is described in further detail.

[0019] Example 1:

[0020] A rotary drum type fine screen slag cleaning device includes a pipe shell 1, the outer wall of the pipe shell 1 is fixedly connected to a frame 5, the outside of the frame 5 is fixedly installed with a fine screen 6, sewage flows into the front end of the fine screen 6 of the fine screen decontamination machine and flows out from the gap in the fine screen 6, while the filter residue is trapped inside the fine screen 6, the pipe shell 1 is located on the inner wall of the fine screen 6 and is fixedly connected to a filter residue collection frame 12, the inner wall of the filter residue collection frame 12 is rotatably connected to a drive shaft 8, and the outer wall of the drive shaft 8 is fixedly connected to a spiral blade 9, which is convenient for The filter residue is collected, and the driving shaft 8 drives the spiral blade 9 to rotate, and then the spiral blade 9 spirally raises the filter residue in the filter residue collection frame 12 to the next operation step, which is convenient for cleaning and discharging the filter residue. The spiral blade 9 passes through the filter residue collection frame 12 and is fixedly connected to the connecting frame 13. The outer wall bolts of the connecting frame 13 are equipped with rake teeth 14, and the ends of the rake teeth 14 are extended into the gaps of the fine grid 6, so that the driving shaft 8 drives the rake teeth 14 to rotate through the connecting frame 13, and then the rake teeth 14 are pressed against the fine grid 6. The filter residue is cleaned, and when the rake teeth 14 rotate to the top of the filter residue collection frame 12, the filter residue falls into the filter residue collection frame 12, thereby transporting it. The frame 5 is located on one side of the fine grid 6 and is bolted with a cleaning tooth plate 15, and the cleaning tooth plate 15 is adapted to the rake teeth 14. The cleaning tooth plate 15 facilitates the cleaning of the filter residue remaining on the rake teeth 14, and then facilitates the next step of the rake teeth 14 to clean the fine grid 6. The outer walls of the frame 5 on both sides of the cleaning tooth plate 15 are fixedly installed with water pipes 16, and the outer walls of the water pipes 16 are fixedly installed with Multiple high-pressure nozzles 17, a three-way pipe 18 is fixedly installed on the outer wall of the frame 5 away from the two water pipes 16, and the three-way pipe 18 is connected to the two water pipes 16. By connecting the three-way pipe 18 to an external water source, the water source is sprayed out through the multiple high-pressure nozzles 17 at high speed, and the multiple high-pressure nozzles 17 are all aimed at the cleaning tooth plate 15, which makes it convenient to flush the filter residue remaining on the cleaning rake teeth 14 of the cleaning tooth plate 15, and facilitates the cleaning of the rake teeth 14 by the cleaning tooth plate 15 next time, thereby improving the work efficiency of cleaning the filter residue on the fine grid 6.

[0021] The outer wall of the pipe shell 1 is fixedly connected to the sewage treatment pipe 2, the interior of the sewage treatment pipe 2 is fixedly connected to the filter pipe 10, and a sewage trough 11 is arranged between the filter pipe 10 and the sewage treatment pipe 2, the outer wall of the sewage trough 11 is fixedly connected to the capillary tube 7, and the capillary tube 7 is connected to the frame 5 and the sewage trough 11, and the filter residue is transported to the sewage treatment pipe 2 through the drive shaft 8 and the spiral blade 9, and the filter pipe 10 is arranged inside the sewage treatment pipe 2. During the filter residue transportation process, the drive shaft 8 and the spiral blade 9 have a certain squeezing effect on the filter residue, and the residual sewage flows into the sewage trough 11 through the filter pipe 10, and then flows back into the canal through the capillary tube 7.

[0022] The outside of the sewage treatment pipe 2 is fixedly connected to a discharge pipe 3, through which the filter residue is easily discharged.

[0023] The outer wall of the discharge pipe 3 is fixedly connected to the reduction motor 4, and the output shaft of the reduction motor 4 is fixedly connected to the drive shaft 8. The reduction motor 4 is started by an external power supply, so that the output shaft of the reduction motor 4 can mobilize the drive shaft 8 to rotate.

[0024] The outer walls of both sides of the filter residue collecting frame 12 are fixedly connected with expansion plates 19 , which facilitate the filter residue to fall into the filter residue collecting frame 12 .

[0025] The implementation principle of a rotary drum type fine screen cleaning device in the embodiment of the present application is as follows: first, the device is installed at an angle of 30 degrees to the ground, so that the fine screen 6 on the frame 5 enters the water channel; when the water level difference before and after the spiral fine screen machine 5 reaches the set value, the reduction motor 4 is started by an external power supply, so that the reduction motor 4 drives the drive shaft 8 to rotate, ensuring that the spiral blades 9 on the drive shaft 8 rotate, and at the same time, the drive shaft 8 is fixedly connected to the connecting frame 13, so that when the spiral blades 9 rotate, the connecting frame 13 also rotates at the same time, and the rake teeth 14 on the connecting frame 13 correspond to the fine screen 6, so that the rotating rake teeth 14 cleans the filter residue on the fine screen 6, and then the rake teeth 14 drives the filter residue to the vertical direction of the filter residue collecting frame 12, so that the filter residue falls into the filter residue collecting frame 12, and when the rake teeth 14 rotate to the vertical direction, the cleaning tooth plate 15 is rotated to the rake teeth 14 through the rotation of the rake teeth 14. The residue in the gap is cleaned, which makes it easier for the rake teeth 14 to clean the fine screen 6. Before that, the three-way pipe 18 is connected to the water source, so that water is sprayed at high speed from the multiple high-pressure nozzles 17 on the water pipe 16. Since the spray direction of the multiple high-pressure nozzles 17 on both sides of the cleaning tooth plate 15 is aligned with the cleaning tooth plate 15, the residual residue of the cleaning rake teeth 14 in the cleaning tooth plate 15 is flushed, and the residual residue in the cleaning tooth plate 15 falls into the filter residue collection frame 12, which makes it easier for the cleaning tooth plate 15 to clean the rake teeth 14 next time. Secondly, after the filter residue enters the filter residue collection frame 12, the spiral blade 9 drives the filter residue to spirally rise and squeeze the filter residue at the same time. When the filter residue enters the interior of the sewage treatment pipe 2, the sewage squeezed out of the filter residue enters the sewage trough 11 outside through the filter screen pipe 10, and then flows into the frame 5 through the fine tube 7 and re-enters the canal. The filter residue can be discharged into the collection box through the discharge pipe 3.

[0026] The above describes an exemplary implementation of a rotary drum fine screen slag cleaning device provided by the present disclosure with reference to a preferred embodiment. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various variations and modifications can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
