[0039] Please refer to the attached document. Figures 1-5 In this embodiment, the drum rotation assembly 100 includes a cylinder 10, a drum rotation module 20, and a scraper 30. The cylinder 10 includes a cylinder body 11 and a top cover 12. The cylinder body 11 is provided with a sludge inlet 11a and a sludge receiving space 11b. The sludge inlet 11a is used to connect to an external sludge input pipe. The drum rotation module 20 includes a power module 21 and a drum 22. The power module 21 is connected to the top cover 12 and drives the drum 22. The drum 22 is located in the sludge receiving space 11b and rotates along its own axis under the drive of the power module 21. When the drum 22 is rotating, it drives the sludge input through the sludge inlet 11a to rotate in the sludge receiving space 11b and performs rotary separation of the sludge. The scraper 30 is installed on the cylinder 10 and is located on the outer periphery of the drum 22. The scraper 30 extends toward the drum 22 and scrapes away the sludge on the peripheral wall of the drum 22, so that the drum 22 can drive the sludge to rotate in a ring, thereby facilitating the gradual separation of sludge along different heights to achieve automated separation and avoid sludge separation under human intervention. At the same time, the scraper 30 prevents sludge from accumulating on the peripheral wall of the drum 22, preventing the drum 22 from clogging and improving the sludge separation efficiency of the drum rotation assembly 100.

[0040] Please refer to the attached document. Figures 1-5In this embodiment of the application, the cylinder 10 includes a cylinder body 11 and a top cover 12; the cylinder body 11 is provided with a sludge inlet 11a and a sludge receiving space 11b; the sludge inlet 11a is used to connect to an external sludge input pipe; so that the sludge output from the external sludge input pipe can enter the sludge receiving space 11b through the sludge inlet 11a; the top cover 12 is disposed on the upper side of the cylinder body 11 and covers the top of the sludge receiving space 11b to prevent the sludge in the sludge receiving space 11b from flowing to the external environment through the top.

[0041] The drum rotation module 20 includes a power module 21 and a drum 22. The power module 21 is connected to the top cover 12 and drives the drum 22. The drum 22 is located in the sludge receiving space 11b and rotates along its own axis under the drive of the power module 21, so that the drum 22 can rotate automatically. When the drum 22 is rotating, it drives the sludge input through the sludge inlet 11a to rotate in the sludge receiving space 11b and performs rotary separation of the sludge. This allows the drum 22 to drive the sludge to rotate in a ring, which facilitates the gradual separation of the sludge along different heights, thereby achieving automated separation and avoiding the need for manual separation of the sludge, thus improving the sludge separation efficiency of the drum rotation assembly 100.

[0042] The sludge scraper 30 is installed on the cylinder 10 and is located on the outer periphery of the roller 22. The sludge scraper 30 extends toward the roller 22 and scrapes off the sludge on the peripheral wall of the roller 22. The sludge scraper 30 prevents the accumulation of sludge on the peripheral wall of the roller 22 and prevents the roller 22 from becoming clogged.

[0043] Please refer to the attached document.

The rotation of the drum 22 forces the sludge to spiral up / down, prolongs the residence time, enhances the heat transfer or reaction efficiency of the sludge, and the spiral flow reduces sludge adhesion.

[0044] Please refer to the attached document. Figures 1-4 In this embodiment, the peripheral wall of the roller 22 is provided with multiple water passage holes 22b, which are arranged in a ring along the peripheral wall of the roller 22. The water passage holes 22b are used for water separated from sludge to pass through, but not for sludge to pass through, so that the water separated from sludge can enter the inner wall of the roller 22 through the water passage holes 22b, thereby facilitating the separation of water and sludge. The arrangement of multiple water passage holes 22b increases the flow efficiency of water.

[0045] Please refer to the attached document. Figures 1-4 In this embodiment, the drum 22 is provided with a water passage space 22c. The water passage space 22c is connected to multiple water passage holes 22b in different directions, so that the water separated from the sludge in the annular space 22a can flow to the water passage space 22c through the multiple water passage holes 22b, thereby facilitating the storage of the separated water in the water passage space 22c. The water passage space 22c can be connected to an external water pipe. The water passage space 22c is arranged in an annular shape so that the water in the water passage space 22c can be discharged to the external environment through the external water pipe, thereby achieving the water discharge effect of the water passage space 22c.

[0046] Please refer to the attached document. Figures 1-4 In this embodiment, the roller 22 is rotatably connected to the cylindrical body 11 so as to adjust the position of the roller 22 relative to the cylindrical body 11. The roller 22 is suspended from the cylindrical body 11. The roller 22 is supported by the power module 21 so as to achieve a suspended state relative to the cylindrical body 11, so that the outer wall of the roller 22 and the inner wall of the cylindrical body 11 form an annular space 22a.

[0047] The power module 21 includes a power motor 211 and a reduction module 212. The power motor 211 is located on the outside of the top cover 12, and the reduction module 212 is connected to the top cover 12. One end of the reduction module 212 is connected to the power motor 211, and the other end is connected to the roller 22, which drives the roller 22 to rotate, so that the roller 22 can automatically rotate relative to the main body 11 through the cooperation of the power motor 211 and the reduction module 212.

[0048] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the inner sidewall of the cylindrical body 11 is provided with an installation groove 11c, which faces the annular space 22a so that the installation groove 11c is connected to the annular space 22a. The installation groove 11c is used for the installation of the sludge scraper 30 so that the sludge scraper 30 is fixed to the inner sidewall of the cylindrical body 11 through the installation groove 11c, thereby facilitating the extension of the sludge scraper 30 to the annular space 22a through the installation groove 11c.

[0049] Please refer to the attached document. Figures 1-5 In this embodiment, the sludge scraper 30 is provided with an installation part 31 and a sludge scraping arm 32. The installation part 31 is installed in the installation groove 11c so that the sludge scraper 30 can be connected to the installation groove 11c through the installation part 31.

The sludge scraping arm 32 elastically contacts the peripheral wall of the roller 22 so that the sludge scraping arm 32 can scrape the sludge on the peripheral wall of the roller 22. The sludge scraping arm 32 prevents the accumulation of sludge on the peripheral wall of the roller 22 and prevents the roller 22 from clogging.

[0050] Please refer to the attached document. Figures 1-5In this embodiment, the sludge scraper 30 is a flexible component, and the sludge scraper arm 32 swings flexibly relative to the mounting part 31 and swings along the connection between the sludge scraper arm 32 and the mounting part 31, so as to adjust the position of the sludge scraper arm 32 relative to the roller 22, thereby making it easier for the sludge scraper arm 32 to maintain a constant contact pressure relative to the roller 22 during the swinging process, and to avoid the sludge scraper arm 32 from getting stuck with the roller 22.

[0051] Please refer to the attached document. Figure 3 In this embodiment of the application, the main body 11 of the cylinder is provided with a sludge discharge port 11d, which is used to connect to an external sludge discharge pipe. The sludge discharge port 11d is used for sludge in the annular space 22a or sludge detached from the peripheral wall of the drum 22 to pass through, so that the sludge in the annular space 22a or sludge detached from the peripheral wall of the drum 22 can flow through the sludge discharge port 11d to the external sludge discharge pipe, thereby facilitating the discharge of the sludge in the annular space 22a or sludge detached from the peripheral wall of the drum 22.
