[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a sludge thickening treatment device, including a thickening tank 1, a motor 2 is fixedly connected to the top of the thickening tank 1, the output end of the motor 2 passes through the inner wall of the thickening tank 1 and is fixedly connected to a driving gear 3, a triangular plate 5 is rotatably connected between the driving gear 3 and the output end of the motor 2, a plurality of driven gears 4 are rotatably connected to the bottom of the triangular plate 5, a stirring rod 7 is fixedly connected to the bottom of the driven gear 4, a plurality of stirring blades 8 are fixedly connected to the outside of the stirring rod 7, a gear ring 6 is fixedly connected to the inner wall of the thickening tank 1, a filter box 9 is arranged on the right side of the outside of the thickening tank 1, a filter plate 10 is installed inside the filter box 9 through a clamping assembly, the outer side of the driving gear 3 is meshed with the plurality of driven gears 4 respectively, and the outer sides of the plurality of driven gears 4 are meshed with the inner side of the gear ring 6 respectively.

[0024] Specifically, the sludge can be treated through the concentration tank 1 to reduce the water content in the sludge and realize the sludge concentration operation. The operation of the motor 2 can drive the driving gear 3 to rotate, and then the multiple driven gears 4 meshed and connected on the outside thereof can rotate. The driven gear 4 is combined with the gear ring 6, so that the driven gear 4 can achieve the effect of moving while rotating and under the support of the triangular plate 5, thereby driving the stirring rod 7 to rotate. The multiple stirring blades 8 connected to the outside of the stirring rod 7 can fully stir the sludge, so that the mixing between the sludge and the treatment agent is more uniform, and the reaction speed is also faster, thereby improving the working efficiency of the sludge concentration. The filtrate in the sludge can be filtered through the filter plate 10 installed inside the filter box 9, reducing the discharge of particles and impurities and improving the clarity of the filtrate.

[0025] Reference Figure 3 and Figure 4 The clamping assembly includes two limit grooves 12, which are respectively opened on the left and right sides of the filter plate 10. A spring 14 is fixedly connected to one side of the limit groove 12, and a moving block 13 is fixedly connected to the other end of the spring 14. A pull rope 15 is fixedly connected to one side of the moving block 13. The proximal ends of the two pull ropes 15 are fixedly connected to the rotating rod 11, and a clamping block 16 is fixedly connected to the other side of the moving block 13. Slots 17 are opened on the left and right sides of the filter box 9. The outside of the moving block 13 is slidably connected to the inner wall of the limit groove 12, the outside of the spring 14 is slidably connected to the inner wall of the limit groove 12, the longitudinal section of the clamping block 16 is set to a square, the outside of the clamping block 16 is slidably connected to the inside of the slot 17, the outside of the pull rope 15 is slidably connected to the inside of the filter plate 10, and the bottom of the rotating rod 11 is rotatably connected to the inside of the filter plate 10.

[0026] Specifically, the movement of the moving block 13 and the spring 14 can be restricted by the limit groove 12, so that when the rotating rod 11 is twisted, the pull rope 15 can be driven to reel in, and the moving block 13 is pulled to move inside the limit groove 12 by the two pull ropes 15, thereby causing the spring 14 to contract, and the moving block 13 can drive the card block 16 to disengage from the card slot 17, so that the filter plate 10 can be taken out of the filter box 9 and then cleaned to avoid clogging of the filter screen due to long-term use, thereby affecting the filtering effect. The longitudinal section of the card block 16 is set to be square, so that when the card block 16 is inserted into the inside of the card slot 17, the splicing is more firm, so that the filter plate 10 is not easy to loosen after installation. The spring 14 can release elastic potential energy when the filter plate 10 is installed, and push the card block 16 into the card slot 17 to complete the plug-in fit, thereby fixing the filter plate 10.

[0027] Reference Figure 1 and Figure 3A feed inlet 18 is provided on the left side of the outside of the concentration tank 1, a supernatant outlet 19 is provided on the right side of the outside of the concentration tank 1, a discharge port 21 is provided at the bottom of the concentration tank 1, the outside of the filter plate 10 is slidably connected to the inner wall of the filter box 9, and a filtrate outlet 20 is provided on the outside of the filter box 9.

[0028] Specifically, the sludge to be treated can be injected into the concentration tank 1 through the feed port 18 to facilitate subsequent treatment. The supernatant generated by the treated sludge can be discharged through the supernatant outlet 19 and then transported to the storage tank. The treated sludge is discharged into the mud hopper through the discharge port 21 to realize the collection of the concentrated sludge. After the filtrate is filtered through the filter plate 10 inside the filter box 9, it can be discharged from the filtrate outlet 20 for the next step of treatment. At the same time, impurities and particulate matter mixed therein are reduced, and the clarity is improved.

[0029] Working principle: When using this device, sludge can be injected into the concentration tank 1 through the feed port 18, and then the motor 2 can be started after adding the agent into the tank. The operation of the motor 2 drives the driving gear 3 to rotate, and with the cooperation of the gear ring 6 fixed inside the concentration tank 1, the three driven gears 4 are rotated at the bottom of the triangular plate 5, so as to drive the stirring rod 7 to rotate, and stir the sludge in the tank through the multiple stirring blades 8 connected to the outside, so as to speed up the mixing of the sludge and the treatment agent, increase the reaction rate, and thus concentrate the sludge. The clear liquid produced by the treated sludge will be discharged from the supernatant outlet 19, and the filtrate in the sludge will enter the filter box 9 installed outside the concentration tank 1, and after being filtered by the filter plate 10, it will be discharged from the filtrate outlet 20 to the filtrate buffer tank.

[0030] If the filter plate 10 needs to be disassembled for cleaning, the rotating rod 11 on the top of the filter box 9 can be rotated to drive the two pull ropes 15 connected to the bottom to contract, thereby making the moving block 13 connected to the other end of the pull rope 15 slide inside the limit groove 12, applying pressure to the spring 14 to make it contract, and at the same time driving the card block 16 to disengage from the card slot 17. At this time, the filter plate 10 can be removed from the inside of the filter box 9 for cleaning or replacement, thereby avoiding clogging after long-term use that affects the filtering effect. When installing, repeat the above steps and release the rotating rod 11 when the card block 16 corresponds to the card slot 17, so that the spring 14 releases its elastic potential energy, pushing the card block 16 and the card slot 17 to complete the plug-in fit, thereby fixing the filter plate 10. Fixing the filter plate 10 by card connection makes it easy to disassemble and clean the filter plate 10, thereby reducing the maintenance cost of the equipment.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
