[0034] Please refer to the attached document. Figures 1-4 This utility model provides a cylindrical assembly 100, which is applied to sludge treatment equipment and is used to discharge sludge.
[0035] Please refer to the attached document. Figures 1-4 In this embodiment, the cylinder assembly 100 includes a cylinder 10 and a drum 20. The cylinder 10 is provided with a sludge feed channel 10a, which is used to connect to an external sludge input pipe. The drum 20 is located inside the cylinder 10, rotatably connected to the cylinder 10, and rotates along its own axis. An annular space 20a is formed between the peripheral wall of the drum 20 and the inner wall of the cylinder 10. The annular space 20a is connected to the sludge feed channel 10a and contains the sludge fed through the sludge feed channel 10a. The drum 20 performs rotary separation of the sludge fed through the sludge feed channel 10a while rotating. The cylinder 10 is also provided with a sludge discharge function. The space 10b and the mud discharge port 10c are connected. The mud discharge space 10b is located below the annular space 20a and is connected to the mud discharge port 10c. The mud discharge space 10b is arranged in a cone shape. The mud that descends through the annular space 20a contacts the end of the mud discharge space 10b and converges in different directions to the mud discharge port 10c. The mud discharge port 10c is located in the middle of the mud discharge space 10b, so that the cone-shaped mud discharge space 10b can make the mud slide down the inclined wall of the mud discharge space 10b and finally converge at the tip of the cone and flow to the mud discharge port 10c, avoiding the blockage of the mud discharge port 10c, realizing efficient confluence at the tip of the cone, and improving the smoothness of mud discharge of the cylinder assembly 100.
[0036] Please refer to the attached document. Figures 1-4 In this embodiment of the application, the cylinder 10 is provided with a sludge feeding channel 10a; the sludge feeding channel 10a is used to connect to an external sludge input pipe; so that the sludge output from the external sludge input pipe can enter the cylinder 10 through the sludge feeding channel 10a.
[0037] The roller 20 is located inside the cylinder 10. The roller 20 is rotatably connected to the cylinder 10 and rotates along its own axis to adjust the position of the roller 20 relative to the cylinder 10. An annular space 20a is formed between the peripheral wall of the roller 20 and the inner wall of the cylinder 10. The annular space 20a is connected to the sludge feed channel 10a.
[0038] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the cylinder 10 is connected to a guide disk 11, which is close to the opening of the mud discharge space 10b. The peripheral sidewall of the guide disk 11 is provided with an annular guide sidewall 11a, which extends toward the annular edge of the mud discharge space 10b and guides the mud falling through the roller 20 into the mud discharge space 10b, so that the mud falling from the roller 20 is blocked by the sidewall of the mud discharge space 10b no matter which side it lands on, thus preventing the mud from splashing outward into the gap between the cylinder wall and the annular space 20a.
[0039] Please refer to the attached document. Figures 1-4 In this embodiment of the application, an annular guide space is provided between the annular guide sidewall 11a of the guide disc 11 and the inner sidewall of the roller 20. The annular guide space is located between the annular space 20a and the mud discharge space 10b, and connects the annular space 20a and the mud discharge space 10b. The annular guide space is used for mud falling through the roller 20 to pass through and guide the mud to the annular edge of the mud discharge space 10b, so that the mud in the annular space 20a can flow to the mud discharge space 10b under the guidance of the annular guide space, thus ensuring the flow direction of the mud.
[0040] Please refer to the attached document. Figures 1-3 In this embodiment, the mud enters the annular edge of the mud discharge space 10b and converges at the mud discharge port 10c along the inclined direction of the mud discharge space 10b, so as to reduce the impact and wear of the mud on the inner wall of the cylinder 10 and improve the continuity and controllability of the mud discharge flow.
[0041] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the mud discharge space 10b is provided with an inclined inner wall 10d. The inclined inner wall 10d is arranged at a downward angle and guides the mud to flow toward the mud discharge port 10c so that it enters the mud discharge port 10c in different directions. This is so that the inclined inner wall 10d decomposes the gravity on the mud into a component force that always flows downward along the slope, so that the direction of movement of all mud is forced to be unified to the trajectory flow of the mud discharge port 10c, regardless of the initial landing point, thus eliminating random splashing or stagnation of mud.
[0042] Please refer to the attached document. Figures 1-3In this embodiment of the application, the cylinder 10 is connected to a mud discharge pipe 12, which is arranged in an L-shape and connected to the mud discharge port 10c, so that the mud discharged from the mud discharge port 10c can be discharged to the external environment through the mud discharge pipe 12. The mud flow direction is turned by the L-shaped mud discharge pipe 12.
[0043] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the annular space 20a, the annular guide space and the mud discharge space 10b are stacked in the vertical direction so that the mud in the annular space 20a passes through the annular guide space and the mud discharge space 10b in sequence from top to bottom under its own gravity, thus ensuring the movement trajectory of the mud.
[0044] Please refer to the attached document. Figures 1-2 In this embodiment of the application, the cylinder assembly 100 further includes a power motor 30, which is connected to the cylinder 10 and the roller 20, and drives the roller 20 to rotate along its own axis, so that the roller 20 can rotate relative to the cylinder 10 under the driving action of the power motor 30, thereby realizing the automatic rotation effect of the roller 20.
[0045] Please refer to the attached document. Figures 1-4 In this embodiment, the peripheral wall of the drum 20 is provided with multiple water passage holes 20b, which are arranged in a ring along the peripheral wall of the drum 20. The water passage holes 20b 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 flow through the water passage holes 20b to the inner side of the drum 20, thereby facilitating the separation of mud and water from sludge and ensuring the sludge separation effect.
[0046] In a second embodiment, a sludge treatment device includes a cylindrical assembly 100, which is part of the sludge treatment device. The sludge treatment device processes sludge and separates the mud and water from the sludge.
[0047] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
