[0003] The sludge processing includes thickening, stabilization, dewatering, drying, harmless treatment, and resource utilization. During thickening, the sludge needs to be mixed with inoculated sludge so that the organic matter in the sludge can be better decomposed and transformed by microorganisms.

[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 5As shown in the embodiment of this utility model, the sludge chemical conditioning multi-stage mixing process device includes a processing cylinder 1, with a top cover 17 fixedly connected to the top of the processing cylinder 1; a feeding port 11 fixedly connected to the top of the top cover 17; a pair of cylinders 12 fixedly connected to the side wall of the feeding port 11; a screen 13 disposed in the middle of the cylinder 12; the screen 13 is rotatably connected inside the cylinder 12; a first motor 14 fixedly connected to the side wall of the feeding port 11; a support column 15 fixedly connected to the output end of the first motor 14; and the end of the support column 15... A cleaning pendulum 16 is fixedly connected to the cylinder 12; the cleaning pendulum 16 and the support column 15 are rotatably connected; a pair of agent inlets 18 are fixedly connected to the side wall of the processing cylinder 1; during operation, the sludge is first placed inside the cylinder 12, and then the sludge falls to the top of the screen 13. After falling to the top of the screen 13, the sludge continues to move downward through the perforations on the screen 13. Debris and leaves attached to the sludge will fall onto the screen 13. When a large amount of sludge enters the top of the screen 13 together, the screen 13 will... If sludge becomes stuck or moves slowly, the first motor 14 can be started. The first motor 14 then drives the support column 15 to rotate. When the support column 15 rotates, the cleaning pendulum 16 at the end of the support column 15 will also rotate. When the cleaning pendulum 16 rotates, it will strike the screen 13, and then the screen 13 will be driven to rotate on the cylinder 12. At this time, the sludge will fall into the processing cylinder 1 through the screen 13 at a relatively fast speed. Impurities and leaves will stay on the top of the screen 13. When it is necessary to inject chemical reagents into the processing cylinder 1, the chemical reagents can be placed into the reagent inlet 18, and then the chemical reagents will flow into the processing cylinder 1 through the reagent inlet 18. By adding the screen 13, impurities on the sludge can be filtered out, which facilitates better mixing of the sludge in the processing cylinder 1. At the same time, adding the cleaning pendulum 16 can reduce the sludge getting stuck on the top of the screen 13, allowing the sludge to enter the processing cylinder 1 more quickly, which is convenient for subsequent sludge processing and mixing.
[0026] like Figures 1 to 3As shown, a second motor 21 is fixedly connected to the bottom of the processing cylinder 1; a support rod 22 is fixedly connected to the output end of the second motor 21; a stirring rod 2 is provided in the middle of the support rod 22; a scraper 23 is provided in the middle of the support rod 22; the stirring rod 2 and the scraper 23 are rotatably connected to the support rod 22; during operation, after the sludge enters the processing cylinder 1, the second motor 21 can be started, and then the second motor 21 will drive the support rod 22 to start rotating. When the support rod 22 rotates, the stirring rod 2 and the scraper 23 inside the support rod 22 will also rotate. When the stirring rod 2 rotates, the sludge will be stirred by the stirring rod 2, and when the scraper 23 rotates, it will scrape the sludge against the wall; by adding the stirring rod 2, the sludge can be fully stirred after entering the processing cylinder 1. At the same time, by adding the scraper 23, the sludge remaining on the inner wall of the processing cylinder 1 can be scraped off during the stirring process, reducing the occurrence of sludge adhering to the inner wall of the processing cylinder 1 for a long time and solidifying later, which is inconvenient to handle.
[0027] like Figures 1 to 4 As shown, a pair of partitions 31 are provided inside the processing cylinder 1; heating elements 3 are provided inside the partitions 31; the heating elements 3 and the partitions 31 are arranged correspondingly; during operation, when the sludge is stirred inside the processing cylinder 1, the heating elements 3 inside the partitions 31 can be activated, and then the heating elements 3 will heat the inner wall of the processing cylinder 1, and the sludge will also be heated together; by adding heating elements 3, the sludge can be kept at a relatively warm temperature when it is stirred, and the heating elements 3 can soften the sludge, reduce the situation where the sludge temperature is too low and the sludge becomes too hard, effectively shorten the stirring time of the stirring rod 2 on the sludge, and increase the processing progress.
[0028] like Figures 1 to 3 As shown, a water tank 41 is fixedly connected to the top of the top cover 17; a water outlet pipe 4 is fixedly connected to the end of the water tank 41; during operation, after the sludge is screened by the screen 13, water can be injected into the water tank 41, and then the water will flow out through the water outlet pipe 4 and finally flow into the top of the screen 13. At this time, the sludge remaining at the perforated part of the screen 13 will be cleaned and softened; by adding the water outlet pipe 4, the screen 13 can be cleaned in time after the work is completed, reducing the residual sludge on the top of the screen 13, which may solidify if not treated for a long time.
[0029] like Figure 4As shown, the outer wall of the processing cylinder 1 has multiple round holes 51; a sleeve 5 is fitted onto the outer wall of the processing cylinder 1; the sleeve 5 is slidably connected to the outer wall of the processing cylinder 1; during operation, after the sludge is mixed, the sleeve 5 can be slid and removed from the outer wall of the processing cylinder 1, and after removal, the round holes 51 will discharge the odor inside the processing cylinder 1; by adding the sleeve 5, the residual odor inside the processing cylinder 1 can be discharged in time after the sludge is processed and mixed inside the processing cylinder 1, and after the odor is discharged, it is convenient to continue mixing and processing the sludge next time.
[0030] like Figure 5 As shown, a discharge pipe 61 is fixedly connected to the bottom of the processing cylinder 1; a baffle 62 is provided at the bottom of the discharge pipe 61; a filter screen 6 is fixedly connected inside the discharge pipe 61; during operation, after the sludge processing and mixing are completed, the baffle 62 can be removed, and the residual wastewater on the sludge will flow out through the discharge pipe 61, while the fine sludge attached to the wastewater will be blocked by the filter screen 6; by adding the discharge pipe 61, the residual wastewater after the sludge mixing is completed can be discharged, and at the same time, adding the filter screen 6 can separate the sludge and wastewater, making it easier to process the sludge in the future.
[0031] Working principle: During operation, sludge is first placed inside cylinder 12, then falls to the top of screen 13. After falling to the top of screen 13, the sludge continues to move downwards through the perforations on screen 13. Debris and leaves attached to the sludge will fall onto screen 13. When a large amount of sludge enters the top of screen 13 at once, screen 13 may experience sludge jamming or slow movement. At this time, the first motor 14 can be started, which then drives the support column 15 to rotate. As the support column 15 rotates, the cleaning pendulum at the end of the support column 15... Hammer 16 also rotates, striking screen 13 as it rotates. Screen 13 is then driven to rotate on cylinder 12, causing sludge to fall rapidly through screen 13 into processing cylinder 1. Impurities and leaves remain at the top of screen 13. When chemical reagents need to be injected into processing cylinder 1, they can be placed into reagent inlet 18, flowing into processing cylinder 1. During operation, after the sludge enters processing cylinder 1, the second motor 21 can be started. Subsequently, the second motor 21 drives the support rod 22 to rotate. As the support rod 22 rotates, the stirring rod 2 and scraper 23 inside it also rotate. The stirring rod 2 agitates the sludge, and the scraper 23 scrapes the sludge against the wall. During operation, while the sludge is agitated inside the processing cylinder 1, the heating element 3 inside the partition 31 can be activated. The heating element 3 then heats the inner wall of the processing cylinder 1, simultaneously heating the sludge. After the sludge is sieved by the screen 13, at this time... Water can be added into the water tank 41, and then the water will flow out through the outlet pipe 4 and finally flow into the top of the screen 13. At this time, the sludge remaining at the perforated part of the screen 13 will be cleaned and softened. During operation, after the sludge is mixed, the sleeve 5 can be slid and removed from the outer wall of the processing cylinder 1. After removal, the round hole 51 will discharge the odor inside the processing cylinder 1. During operation, after the sludge is processed and mixed, the baffle 62 can be removed. Then the wastewater remaining on the sludge will flow out through the discharge pipe 61, and the fine sludge attached to the wastewater will be blocked by the filter screen 6.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
