[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described as follows:

[0019] A drum-type pipeline sewage treatment device includes a filter drum box 1 and a drive impeller box 2 fixedly installed on one side of the filter drum box 1. A filter cleaning device is rotatably installed inside the filter drum box 1. A drive device for driving the filter cleaning device is rotatably installed in the drive impeller box 2. An inlet pipe 3 is horizontally installed on one side of the middle of the filter drum box 1 and communicates with its inner cavity. A connecting pipe 4 is horizontally installed on the other side of the middle of the filter drum box 1 and communicates with its inner cavity. The connecting pipe 4 is sealed to the filter cleaning device. The other end of the connecting pipe 4 passes through the top of the drive impeller box 2 and communicates with its inner cavity. An outlet pipe 5 is installed at the bottom of the drive impeller box 2 and communicates with its inner cavity. A sewage discharge pipe 6 is installed at the bottom of the filter drum box 1 and communicates with its inner cavity. A sewage discharge valve 7 is installed on the sewage discharge pipe 6.

[0020] In this embodiment, one end of the inlet pipe 3 is connected to the water supply pipe, and the other end of the inlet pipe 3 is horizontally connected to the filter drum box 1. The upper end of the outlet pipe 5 is connected to the lower part of the drive impeller box 2, and the lower end of the outlet pipe 5 is connected to the water supply pipe. The connecting pipe 4 is a pipe with three 90-degree bends. The function of the connecting pipe 4 is to guide the relatively clean water filtered by the filter cleaning device in the filter drum box 1 to the drive impeller box 2, so that the drive device can drive the filter cleaning device to rotate and clean the filter material on the filter cleaning device. When the filter material accumulates to a certain amount at the bottom of the filter drum box 1, the drain valve 7 needs to be opened, and the filter material is discharged with the water flow from the drain pipe 6 to the outside of the filter drum box 1. After the filter material is discharged, the drain valve 7 is closed.

[0021] The filter cleaning device includes a filter drum 11 and a brush 13. The filter drum 11 is rotatably installed inside the filter drum box 1. One end of the filter drum 11 is sealed, and the other end of the filter drum 11 is rotatably installed inside the connecting pipe 4 and sealed therewith. Multiple filter holes 12 are opened on the side wall of the filter drum 11. The brush 13 is fixedly installed on the inner wall of the filter drum box 1 on the side away from the water inlet pipe 3. The brush 13 contacts and cooperates with the outer wall of the filter drum 11.

[0022] In this embodiment, sewage from the water supply pipe enters the filter drum box 1 through the horizontally arranged inlet pipe 3. After entering the filter drum box 1, the sewage is filtered through the filter holes 12 on the filter drum 11, resulting in a relatively clean water flow. This water then enters the filter drum 11 and, through the connecting pipe 4, enters the drive impeller box 2 from the top. The drive device then rotates the filter drum 11. When the filter holes 12 filter the sewage, non-sticky or particulate filter material settles downwards to the lower part of the filter drum box 1 due to gravity. Sticky filter material adheres to the outside of the filter drum 11 and rotates with it. When the sticky filter material on the outside of the filter drum 11 rotates to the brush 13, the brush 13 cleans the filter material off the filter drum 11, effectively preventing the filter holes 12 from clogging. After being removed from the filter drum 11 by the brush 13, the filter material gradually sinks under gravity and settles at the lower part of the filter drum box 1. Preferably, the lower part of the filter drum box 1 has sufficient space for the deposition of filter material. The brush 13 is in close contact with the filter drum 11; the brush 13 has both elasticity and softness to ensure that it can clean the filter material on the filter drum 11 without generating excessive resistance. The filter drum 11 is a circular drum with filter holes 12. The diameter of the filter holes 12 can be determined according to the minimum particle size of the impurities to be filtered in the wastewater, and the number of filter holes 12 is determined according to the flow rate to ensure normal flow rate during operation.

[0023] The drive unit includes an impeller shaft 8, which is rotatably mounted in the drive impeller box 2. One end of the impeller shaft 8 extends into the filter drum box 1 and is fixedly connected to the filter drum 11. A drive impeller 9 is fixedly mounted on the outside of the impeller shaft 8 located in the drive impeller box 2, and multiple drive blades 10 are fixedly mounted on the outside of the drive impeller 9.

[0024] In this embodiment, preferably, 12 drive blades 10 are evenly arranged. Relatively clean water flowing from the connecting pipe 4 into the drive impeller box 2 and filtered by the filtration and cleaning device in the filter drum box 1 impacts the drive blades 10, driving the impeller shaft 8 to rotate the filter drum 11. Sticky filter material adhering to the outside of the filter drum 11 is cleaned off by the brush 13 as the filter drum 11 rotates, preventing the filter holes 12 from becoming clogged.
