[0035] Reference Figure 1 to Figure 8When the equipment is running, the driving device 4 drives the main shaft 3 to rotate, and then uses the main shaft 3 to drive the impeller 65 located in the inner cavity of the assembly shell 2 to rotate. During the rotation of the impeller 65, the centrifugal force generated by it is used to throw the sludge slurry around it to the circumferential outer side of the assembly shell 2, so that the sludge slurry is finally discharged through the multiple assembly notches 22 opened on the bearing shell. At this time, the pressure at the center of the impeller 65 is reduced, and the sludge slurry located at the bottom 26 of the inner cavity of the reduction container tank 1 is sucked into the inner cavity of the assembly shell 2 through the input channel 21; during the rotation of the impeller 65, the ozone generator is connected to the air inlet through the rotary joint 64. The channel 63 inputs ozone into the accommodating chamber 61, and the ozone entering the accommodating chamber 61 finally enters the inner cavity of the assembly shell 2 through the multiple aeration holes 62 opened at the bottom end of the main shaft 3. As the impeller 65 rotates at a high speed, the impeller 65 drives the sludge slurry stored in the reduction container tank 1 to generate a vortex, and the sludge in the sludge slurry is cut into sludge fine particles by the impeller 65, and the ozone gas flow output through the aeration holes 62 is cut into ozone microbubbles by the impeller 65. Driven by the vortex, the ozone is highly dissolved in the sludge slurry, so as to achieve the purpose of reducing the sludge slurry stored in the reduction container tank 1.

[0036] When the main shaft 3 drives the impeller 65 to rotate forward at high speed, the guide protrusion 554 is located in the first assembly groove 551, and the solid impurities with larger volume (such as strip-shaped or filament-shaped solid impurities) mixed in the sludge slurry cannot flow out to the outside of the assembly shell 2 through the assembly notch 22. Under the action of centrifugal force, they are gradually guided along the circumferential side wall of the inner cavity of the assembly shell 2 and collected in the circumferential outer edge cavity of the inner cavity top 24 of the assembly shell 2 or the circumferential outer edge cavity of the inner cavity bottom 26 of the assembly shell 2; when the dredging module 5 cleans the circumferential outer edge cavity collected in the inner cavity top 24 of the assembly shell 2, the dredging module 5 cleans the circumferential outer edge cavity of the inner cavity top 24 of the assembly shell 2. When there are solid impurities in the peripheral cavity or the circumferential outer cavity of the inner cavity bottom 26 of the assembly shell 2, the driving device 4 drives the main shaft 3 to rotate in the opposite direction. In this process, the first sleeve 51 drives the guide protrusion 554 to slide from the top of the guide groove 553 into the guide groove 553 under the action of gravity, and then follows the guide of the guide groove 553, and finally enters the second assembly groove 552 through the bottom of the guide groove 553. In this process, the second sleeve 5553 slides downward along the axial direction of the main shaft 3 under the pressure of the thrust ball bearing 5552, compressing the reset spring 5554 to realize Now, the first sleeve 51 is driven to slide downward along the axial direction of the main shaft 3, and the multiple cutters 52 arranged on the first sleeve 51 are driven to be inserted into the multiple assembly notches 22 respectively. The blade portion 521 of the cutter 52 cooperates with the inner cavity side wall of the assembly shell 2 to cut off the solid phase impurities collected in the circumferential outer edge cavity of the inner cavity top 24 of the assembly shell 2 and the circumferential outer edge cavity of the inner cavity bottom 26 of the assembly shell 2. Next, the driving device 4 drives the main shaft 3 to rotate in the positive direction again, and the second sleeve 5553 is driven by the return spring 5554 to push the thrust ball bearing 55 52 and the first sleeve 51 rise, so that the guide slider enters the guide groove 553 from the bottom end of the guide groove 553, and then slides along the guide of the guide groove 553 into the first guide groove 553, so as to achieve the purpose of driving the first sleeve 51 to rise and reset, and then pull out the plurality of cutters 52 from the first assembly notch 22, so that the cut solid impurities are discharged from the assembly notch 22, so as to achieve the purpose of automatically cleaning the solid impurities collected in the circumferential outer edge cavity of the inner cavity top 24 of the assembly shell 2 and the circumferential outer edge cavity of the inner cavity bottom 26 of the assembly shell 2.

[0037] Above, refer to Figure 1 to Figure 8 A sludge reduction treatment device according to an embodiment of the present invention is described, which has the following beneficial effects: 1. The device provides a plurality of assembly notches 22 for outputting sludge slurry on the assembly shell 2 to reduce the possibility that all channels of the assembly shell 2 for outputting sludge slurry are blocked by a larger volume of solid impurities. Even if part of the assembly notches 22 are blocked by solid impurities, it will not have a serious impact on the operation of the device, thereby reducing the frequency of dredging and improving the problem of high daily maintenance costs in the prior art.

[0038] 2. The device further reduces the daily maintenance cost of the device by adding a dredging module 5 to dredge the assembly gap 22 opened on the assembly shell 2 to replace manual dredging.

[0039] 3. The device adopts an assembly shell 2 with a smaller inner diameter in the middle section 25 of the inner cavity and larger inner diameters at the top 24 and bottom 26 of the inner cavity, so that solid impurities located inside the assembly shell 2 that cannot pass through the assembly notch 22 can be guided by the circumferential side wall of the inner cavity of the assembly shell 2 under the action of centrifugal force and gathered at the circumferential outer edge cavity position of the top 24 and bottom 26 of the inner cavity of the assembly shell 2, so that when the tool 52 is inserted downward into the assembly notch 22, it can cooperate with the circumferential side wall of the inner cavity of the assembly shell 2 to cut off the solid impurities and push out the solid impurities with a compact texture stuck in the assembly notch 22, so as to achieve the purpose of unblocking the assembly notch 22 and prevent the assembly notch 22 from being blocked by solid impurities, thereby enhancing the practicality of the device.

[0040] 4. The device is provided with a transmission assembly to utilize the power output when the main shaft 3 rotates forward or reversely to drive multiple tools 52 fixed on the first sleeve 51 to rise or fall vertically, so as to utilize the tools 52 to dredge the assembly gap 22. There is no need to provide an additional power source to independently control the dredging module 5, thereby simplifying the structure of the device itself.
