[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] Please see Figure 1-6As shown, a sludge treatment device for reducing the impact of sludge concentration changes includes a sludge treatment device 1 and a feeding mechanism installed on the sludge treatment device 1. The feeding mechanism is used to filter the water in the sludge and crush and separate larger lumps in the sludge during the sludge feeding process.

[0038] Please refer to Figure 2-4 As shown, the feeding mechanism includes a rotating outer cylinder 12 and a sludge pusher that are rotatably connected to the upper side of the sludge treatment device 1. The sludge pusher is located inside the rotating outer cylinder 12, and the rotating outer cylinder 12 and the sludge pusher rotate in opposite directions. Several water outlet holes 17 are opened on the periphery of the rotating outer cylinder 12, and a discharge ring 13 is fixedly connected to the lower side of the rotating outer cylinder 12.

[0039] At this time, when feeding sludge, the sludge is poured into the interior of the rotating outer cylinder 12, and then the rotating outer cylinder 12 and the sludge pusher are rotated. When the sludge pusher rotates, it will rotate the sludge, causing the sludge to rotate inside the rotating outer cylinder 12, which will generate a large centrifugal force. The water in the sludge will be discharged through the water outlet 17, and the solid material will be discharged through the discharge ring 13.

[0040] Please see Figure 2-3 As shown, the sludge pusher includes a rotating inner cylinder 15 located inside the rotating outer cylinder 12. Both the rotating outer cylinder 12 and the rotating inner cylinder 15 are conical. A working cavity is provided between the rotating outer cylinder 12 and the rotating inner cylinder 15. A spiral pusher 14 adapted to the working cavity is fixedly connected to the outside of the rotating inner cylinder 15. The spiral pusher 14 is spiral in shape. When the rotating inner cylinder 15 rotates, it will drive the spiral pusher 14 to rotate together. When the spiral pusher 14 rotates, it will push the sludge, allowing the sludge to rotate at high speed inside the working cavity.

[0041] To prevent sludge from entering the interior of the rotating inner cylinder 15 during feeding, a conical baffle plate 16 is fixedly connected to the upper side of the rotating inner cylinder 15, while a protective ring 3 is fixedly connected to the upper side of the rotating outer cylinder 12.

[0042] Please also see Figure 4-5 As shown, in order to further improve the water filtration effect of the device, the spiral pusher plate 14 is composed of at least a number of stepped bodies. Each stepped body includes a transversely arranged transverse connecting plate 20. A guide pusher plate 21 is inclinedly fixed at the lower edge of the transverse connecting plate 20. When the guide pusher plate 21 rotates, it pushes the sludge, causing the sludge to move downward during the rotation. At this time, the guide pusher plate 21 separates from the sludge. Then the spiral pusher plate 14 continues to rotate, causing the next guide pusher plate 21 to push the sludge. When the guide pusher plate 21 comes into contact with the sludge, the guide pusher plate 21 will apply a large impact force to the sludge, thereby making the separation of water and solids in the sludge more thorough.

[0043] The sludge treatment unit also includes:

[0044] Please refer to Figure 2 As shown, the water collection assembly is used to collect the water filtered out by the rotating outer cylinder 12;

[0045] The water collection assembly includes a storage tank 2 fixedly connected to the sludge treatment device 1, a rotating outer cylinder 12 rotatably connected inside the storage tank 2, and a drain pipe is provided on the outside of the storage tank 2 to facilitate the discharge of the storage tank 2, and a valve is provided on the drain pipe.

[0046] At this time, in order to prevent the water inside the storage tank 2 from flowing back into the working chamber, the water outlet 17 is opened at an angle, and the end of the water outlet 17 away from the rotating inner cylinder 15 is inclined in the opposite direction to the rotation direction of the rotating outer cylinder 12. At this time, when the rotating outer cylinder 12 rotates at high speed, it can effectively prevent the water inside the storage tank 2 from entering the working chamber.

[0047] The first power unit is used to drive the outer cylinder 12 to rotate;

[0048] Please refer to Figure 2 As shown, the first power assembly includes a second drive motor 6, a drive gear 7, and a driven gear ring 8. The second drive motor 6 is fixedly connected to the outside of the liquid storage tank 2, the drive gear 7 is fixedly connected to the output end of the second drive motor 6, and the driven gear ring 8 is fixedly connected to the outside of the rotating outer cylinder 12. The driven gear ring 8 and the drive gear 7 are meshed together. When the second drive motor 6 is started, it will drive the drive gear 7 to rotate. Because the drive gear 7 and the driven gear ring 8 are meshed together, when the drive gear 7 rotates, it will drive the rotating outer cylinder 12 to rotate through the driven gear ring 8.

[0049] The second transmission component is used to drive the sludge pusher to rotate;

[0050] Please refer to Figure 4 As shown, the second transmission assembly includes a fixed frame 4, a first transmission motor 5, and a rotating shaft 22. The fixed frame 4 is fixedly connected to the liquid storage tank 2, the first transmission motor 5 is fixedly connected to the fixed frame 4, and the rotating shaft 22 is fixedly connected to the output end of the first transmission motor 5. The rotating shaft 22 is also fixedly connected to the rotating outer cylinder 12. When the first transmission motor 5 rotates, it will drive the rotating shaft 22 to rotate together, and when the rotating shaft 22 rotates, it will drive the rotating outer cylinder 12 to rotate.

[0051] The crushing assembly is used to crush lumps in sludge;

[0052] Please refer to Figure 3-4As shown, the crushing assembly includes multiple crushing blades 9, which are fixedly connected to the outside of the rotating shaft 22. When the rotating shaft 22 rotates, it drives the crushing blades 9 to rotate, and the crushing blades 9 crush the blocky material.

[0053] A bulk material separation unit is used to collect non-breakable bulk materials in sludge;

[0054] Please refer to Figure 3-4 As shown, the block separation assembly includes multiple assembly plates 10, which are fixedly connected to the outside of the rotating shaft 22 and located in the gap between multiple crushing blades 9. Filter screens 11 are mounted on the assembly plates 10. When the rotating shaft 22 rotates, it drives the assembly plates 10 to rotate together. The rotation of the assembly plates 10 drives the filter screens 11 to rotate together. When the filter screens 11 rotate, they collect the sludge. Blocks are left inside the filter screens 11, while the remaining components flow out through the filter holes of the filter screens 11.

[0055] Meanwhile, in order to facilitate the installation and disassembly of the filter screen 11, the blocky objects inside the filter screen 11 are tilted out. A magnetic fixing groove 18 is provided on the side of the assembly plate 10 facing its rotation direction. A magnetic assembly frame 19 is magnetically connected inside the magnetic fixing groove 18. The magnetic assembly frame 19 and the filter screen 11 are fixedly connected. The filter screen 11 can be installed and disassembled relatively easily by installing and disassembling the magnetic assembly frame 19.

[0056] In use: Pour the sludge into the inside of the enclosure ring 3, and then start the first drive motor 5 and the second drive motor 6. After the first drive motor 5 starts, it will drive the crushing cutter 9, the assembly plate 10 and the rotating inner cylinder 15 to rotate together through the rotating shaft 22. When the crushing cutter 9 rotates, it will crush the lumps. When the assembly plate 10 rotates, it will drive the filter screen 11 to rotate together. When the filter screen 11 rotates, it will collect the sludge. The lumps will remain inside the filter screen 11, and the rest will flow out through the filter holes of the filter screen 11.

[0057] When the inner cylinder 15 rotates, it will drive the spiral pusher 14 to rotate together. When the spiral pusher 14 rotates, it will push the sludge, causing the sludge to rotate at high speed inside the working chamber.

[0058] At the same time, after the second drive motor 6 starts, it will drive the drive gear 7 to rotate. Because the drive gear 7 and the driven gear ring 8 are meshed and connected, when the drive gear 7 rotates, it will drive the outer cylinder 12 to rotate through the driven gear ring 8. Through the cooperation of the outer cylinder 12, the inner cylinder 15 and the spiral pusher plate 14, the sludge will rotate inside the working chamber, and the centrifugal force will be used to separate the water and solids in the sludge.

[0059] In summary, this invention separates the water and solids in the sludge during the feeding process, making the sludge after feeding roughly uniform. This greatly reduces the impact of different sludge concentrations on the drying and incineration effects of the sludge treatment device 1. Furthermore, by setting up crushing and block separation components, larger blocks in the sludge can be crushed and separated, reducing the impact of blocks on sludge treatment and thus greatly improving the treatment effect of the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
