Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sludge treatment, and particularly to an integrated concentrated sludge treatment device. Background Art
[0002] Conventional sludge treatment often requires multiple independent treatment units to operate sequentially. In the concentration stage, gravity thickeners are commonly used, which have a large footprint and low concentration efficiency, and require a long residence time to initially reduce the volume of sludge. In the subsequent dewatering process, whether using belt filter presses, plate and frame filter presses or centrifuge dewatering machines, corresponding auxiliary facilities such as chemical dosing systems and flushing systems need to be equipped separately. The connection and coordinated operation between various devices require high technical skills from operators, and any negligence is likely to cause failures, affecting the smoothness of the overall treatment process. Traditional sludge treatment processes involve a variety of equipment, and each piece of equipment requires a certain amount of space. For example, gravity thickeners require a large planar area to achieve sludge sedimentation and concentration; various dewatering equipment also requires spacious sites to place the equipment body and related supporting facilities. For sewage treatment plants in cities with increasingly scarce land resources, especially in the central urban areas, this is undoubtedly a heavy burden, not only increasing the construction cost but also restricting the further expansion of the treatment scale.
[0003] To overcome the various drawbacks of traditional sludge treatment methods and meet the growing environmental protection requirements, the development of an integrated concentrated sludge treatment device has become an inevitable trend in the industry. This integrated device aims to integrate multiple treatment links such as sludge concentration and dewatering into a compact equipment unit, and through optimized design and innovative processes, achieve the goals of efficient, energy-saving, environmentally friendly sludge treatment and small footprint, providing a more reliable, economical and convenient sludge treatment solution for modern sewage treatment plants.

[0037] The present invention provides an integrated concentrated sludge treatment device, which includes an integrated stainless steel tank body 1 and a rectangular sludge tank foundation 2 fixedly installed at the bottom of the integrated stainless steel tank body 1. It also includes a balance tank 6 and a concentration tank 7 formed by the cross - intersecting partitions inside the integrated stainless steel tank body 1. There are two groups of both the balance tank 6 and the concentration tank 7, and they are symmetrically distributed on both sides inside the integrated stainless steel tank body 1. The balance tank 6 is used to homogenize the concentrated sludge inside the concentration tank 7, and the concentration tank 7 is used to concentrate and precipitate the muddy water for separation. At the top of the inner wall of the concentration tank 7, a clear water collecting trough 71 is fixedly installed. On one side of the top of the inner wall of the integrated stainless steel tank body 1 near the balance tank 6, a clear water return pipe 5 communicating with the clear water collecting trough 71 is fixedly installed. On the right side of the integrated stainless steel tank body 1, a mixing and flocculation tank 101 is connected. On one side of the rectangular sludge tank foundation 2, a sewage return pipe 3 is connected. On the side of the mixing and flocculation tank 101 away from the integrated stainless steel tank body 1, a muddy water input port 4 is connected. Inside the mixing and flocculation tank 101, three stirring tanks are equidistantly distributed by partitions. On the top of the mixing and flocculation tank 101, a flocculation mechanism is provided, which is used to form firm and stable flocs from the muddy water;
[0038] At the bottom diagonal of the inner wall of the balance tank 6, two submersible mixers 61 are installed, and the diagonally installed submersible mixers 61 are used to stir and homogenize the muddy water inside the balance tank 6.

[0040] The flocculation mechanism includes a stirring motor 102, a stirring rod 103, a flocculant liquid inlet 104, a stirring and mixing cylinder 105, a sewage main pipe 106, and a PAC dosing unit 9. There are three groups of stirring motors 102, which are fixedly installed equidistantly above the three stirring tanks. The stirring rod 103 is fixedly installed at the output end of the stirring motor 102. The flocculant liquid inlet 104 is opened on one side of the top of the integrated stainless steel tank body 1 near the mixing and flocculation tank 101. The stirring and mixing cylinder 105 is fixedly installed at the center inside the mixing and flocculation tank 101 and is used in cooperation with the stirring motor 102. The top of the sewage main pipe 106 is respectively communicated with the centers below the three stirring tanks. The bottom of the sewage main pipe 106 is communicated with a fourth butterfly valve. The PAC dosing unit 9 is arranged on one side of the integrated stainless steel tank body 1, and its output end is communicated to the inside of the mixing and flocculation tank 101 through a pipeline, and is used to add inorganic polymer coagulants to the muddy water in the mixing and flocculation tank 101 for coagulation;
[0041] The three stirring tanks formed inside the mixing and flocculation tank 101 can be stirred separately, and the inorganic polymer coagulants transported by the PAC dosing unit 9 are used to coagulate the muddy water. The flocculated muddy water overflows into the inside of the thickening tank 7 through the flocculant liquid inlet 104, and then undergoes thickening and precipitation. The stirring and mixing cylinder 105 can prevent the inorganic polymer coagulants transported into the muddy water from quickly dispersing into the inside of the thickening tank 7 in a short time, which is convenient for efficiently flocculating the muddy water transported from the muddy water inlet 4 centrally. After flocculation, it gradually overflows into the inside of the thickening tank 7. The sewage main pipe 106 and the fourth butterfly valve cooperate to prevent the muddy water during flocculation inside the mixing and flocculation tank 101 from flowing into the groove of the loop sludge tank foundation 2. When there is too much supernatant inside the thickening tank 7, the fourth butterfly valve inside the sewage main pipe 106 can be opened to facilitate the turbid muddy water in the middle layer inside the thickening tank 7 to seep into the inside of the loop sludge tank foundation 2, and it flows back to the sludge storage tank of the muddy water inlet 4 through the loop sludge tank foundation 2, which is convenient for the muddy water inlet 4 to transport the muddy water to the inside of the mixing and flocculation tank 101 again for flocculation next time.
[0042] The muddy water concentration and cake formation mechanism is arranged on the balance pond 6 and is used to remove moisture from the concentrated muddy water in the balance pond 6 and then discharge it into the external sludge truck hopper. The muddy water concentration and cake formation mechanism includes a first stacked screw dewatering device 8, a second stacked screw dewatering device 81, a screw conveyor 82, a PAM medicine soaking machine 91 and a mixing and pumping assembly. The first stacked screw dewatering device 8 and the second stacked screw dewatering device 81 are fixedly installed side by side on the top of one group of balance ponds 6. The screw conveyor 82 is fixedly installed on the top of the balance pond 6 and is used in cooperation with the mud cake discharge ports of the first stacked screw dewatering device 8 and the second stacked screw dewatering device 81. The mixing and pumping assembly is arranged on one side of the foundation of the loop-shaped sludge pond 2 and is used to pump and transport the homogeneous muddy water at the bottom of the balance pond 6 and the concentrated mud blocks precipitated at the bottom of the concentration pond 7, and transport them to the inside of the first stacked screw dewatering device 8 and the second stacked screw dewatering device 81 for muddy water separation, and transport the separated mud cake to the external sludge truck hopper. The PAM medicine soaking machine 91 is arranged on one side of the integral stainless steel tank body 1, and the output end is connected to the input ends of the first stacked screw dewatering device 8 and the second stacked screw dewatering device 81 through a pipeline, and is used to eliminate the electrostatic repulsion force between sludge particles during the operation of the first stacked screw dewatering device 8 and the second stacked screw dewatering device 81, making it easier for them to approach each other and agglomerate into larger flocs;
[0043] The first stacked screw dewatering device 8 and the second stacked screw dewatering device 81 can separate muddy water from the concentrated mud transported inside the balance pond 6 and the concentration pond 7. Before the muddy water separation, the electrostatic repulsion force between sludge particles is eliminated by the polymer of the PAM medicine soaking machine 91, making it easier for them to approach each other and agglomerate into larger flocs. Subsequently, larger mud cake blocks are obtained during the muddy water separation of the first stacked screw dewatering device 8 and the second stacked screw dewatering device 81, further reducing the moisture content of the sludge. After the first stacked screw dewatering device 8 and the second stacked screw dewatering device 81 discharge the mud cake, it is transported to the hopper of the external sludge truck through the screw conveyor 82, and the muddy water at the bottom of the balance pond 6 and the concentrated muddy water at the bottom of the concentration pond 7 can be stably pumped into the first stacked screw dewatering device 8 and the second stacked screw dewatering device 81 for muddy water separation treatment through the mixing and pumping assembly.

There are two groups of concentrated sludge pumping pipes 803, which are symmetrically arranged on both sides of the integral stainless steel tank body 1. The ends of the two groups of concentrated sludge pumping pipes 803 far from the thickener 7 are respectively connected to the input ends of the first screw conveyor pump 802 and the third screw conveyor pump 806. The end of the concentrated sludge pumping pipe 803 close to the concentrated sludge discharge pipe 701 is connected to the concentrated sludge discharge pipe 701. Two ends of the three-way homogeneous sludge conveying pipe 805 are connected to the bottom drainage outlets of the two groups of equalization tanks 6. A third butterfly valve is connected inside the three-way homogeneous sludge conveying pipe 805. The other end of the three-way homogeneous sludge conveying pipe 805 is connected to the input end of the second screw conveyor pump 804. The output end of the second screw conveyor pump 804 is connected to a homogeneous sludge and water lifting pipe 807. The end of the homogeneous sludge and water lifting pipe 807 far from the second screw conveyor pump 804 is connected to the input end of the first spiral screw dewatering device 8;
[0045] The concentrated sludge discharged from the bottom of the thickener 7 in the concentrated sludge discharge pipe 701 can be transported into the concentrated sludge pumping pipe 803 by opening the first butterfly valve 702. And by starting the first screw conveyor pump 802 and the third screw conveyor pump 806, the sludge in the concentrated sludge pumping pipe 803 is centrally input to the first three-way pipe 801, and then centrally transported to the inside of the first spiral screw dewatering device 8 for treatment. The second screw conveyor pump 804 can pump the homogenized and equalized sludge in the equalization tank 6 into the homogeneous sludge and water lifting pipe 807 by opening the third butterfly valve, and then transport it to the inside of the second spiral screw dewatering device 81 through the homogeneous sludge and water lifting pipe 807 for sludge-water separation treatment. And the water extruded by the first spiral screw dewatering device 8 and the second spiral screw dewatering device 81 is directly discharged into the bottom equalization tank 6, and is homogenized and mixed with the sludge and water transported by the sludge lifting pipe 705 inside the thickener 7 before sludge-water separation.
[0046] The concentrated sludge homogenizing and conveying unit is arranged at the bottom of the thickening tank 7 and is used to pump the sedimented muddy water into the balance tank 6. The concentrated sludge homogenizing and conveying unit includes a concentrated sludge discharge pipe 701, a first butterfly valve 702, a second butterfly valve 703, a fourth screw conveyor pump 704 and a sludge lift pipe 705. The concentrated sludge discharge pipe 701 is connected to the bottom of the inner wall of the thickening tank 7. The first butterfly valve 702 is connected between the concentrated sludge discharge pipe 701 and the concentrated sludge pumping pipe 803. The bottoms of two groups of thickening tanks 7 are respectively connected to two groups and communicate with the concentrated sludge discharge pipe 701.

[0047] The concentrated sludge discharge pipe 701 can cooperate with the concentrated sludge pumping pipe 803 and the sludge lift pipe 705 to respectively transport the concentrated sludge precipitated at the center of the bottom of the thickening tank 7 to the second double-screw dewatering device 81 for treatment and transport it to the inside of the balance tank 6 for homogenization. When it is necessary to transport to the balance tank 6, the first butterfly valve 702 needs to be closed and the second butterfly valve 703 needs to be opened, and the fourth screw conveyor pump 704 is started to transport the concentrated sludge to the inside of the balance tank 6 for homogenization and equalization. When it is necessary to transport the muddy water to the second double-screw dewatering device 81, the second butterfly valve 703 needs to be closed and the first butterfly valve 702 needs to be opened, and the first screw conveyor pump 802 and the third screw conveyor pump 806 are started. The concentrated sludge in the concentrated sludge discharge pipe 701 is pumped to the first tee 801 through the concentrated sludge pumping pipe 803 and enters the inside of the second double-screw dewatering device 81 through the first tee 801. And before that, the electrostatic repulsion force between sludge particles is eliminated by the polymer of the PAM dosing machine 91, making them easier to approach each other and agglomerate into larger flocs, and then the muddy water separation is carried out.

The sludge discharge plate 7321 is fixedly installed at the bottom of the stirring shaft 732 and is used to scrape the center of the bottom of the thickening tank 7 for sludge discharge. The limit mounting plate 735 is fixedly installed on one side of the top of the stirring frame 734 away from the stirring shaft 732. The linkage sludge scraping assembly is arranged on the driven shaft 7356 and is used to drive a number of driven shafts 7356 to rotate synchronously for sludge scraping. A reinforcing plate 7341 is fixedly installed on the inner side of the stirring frame 734 and is used to reinforce the stirring frame 734;
[0049] The thickening area aisle 72 facilitates the inspection personnel to conduct fault inspection above the thickening tank 7. After the speed reduction stirring motor 73 is started, it can drive the stirring shaft 732 to rotate, drive the stirring frame 734 and the reinforcing rib 733 to twist through the stirring shaft 732. During the twisting process, the driven drive assembly drives the sludge scraping plate 7355 and the driven shaft 7356 to rotate, so that the sludge scraping plate 7355 scrapes the bottom of the thickening tank 7, scrapes the thickened sludge to the center of the bottom of the thickening tank 7 for easy discharge. At the same time, the rotating sludge scraping plate 7355 can prevent the thickened sludge from gradually accumulating into a huge mud mass and being difficult to push and scrape, improving the sludge discharge speed and avoiding the situation that the existing sludge scraping place is stationary and no sludge is discharged. The limit bushing 7354 can limit the rotation of a number of driven shafts 7356, and the limit mounting plate 735 can limit the structure on the driven drive assembly.
[0050] The driven drive assembly includes a drive shaft 7351, a driven gear 7352, and a toothed ring 7353. There are two sets of drive shafts 7351, which are symmetrically distributed on both sides of the stirring shaft 732. The bottom is rotatably installed with a limit bushing 7354, and the top is rotatably installed with a limit mounting plate 735. The driven gear 7352 is fixedly installed on the top of the drive shaft 7351 and meshes with the toothed ring 7353. The toothed ring 7353 is fixedly installed on the inner wall of the thickening tank 7 and is located at the top of the stirring frame 734. The top of the sludge scraping plate 7355 is fixedly installed with the bottom of the drive shaft 7351;
[0051] The toothed ring 7353 enables the rotating stirring frame 734 to mesh with the toothed ring 7353 through the driven gear 7352, causing the driven gear 7352 to rotate self - sufficiently. After self - rotation, the driven gear 7352 drives the drive shaft 7351 to rotate. While the drive shaft 7351 rotates, it drives the sludge scraping plate 7355 at its bottom to rotate. And when the drive shaft 7351 rotates, it drives the other twelve sets of driven shafts 7356 to rotate through the linkage sludge scraping assembly and drives the sludge scraping plate 7355 to scrape sludge.
[0052] The linkage sludge scraping assembly includes a first sprocket 7357, a drive chain 7358, a second sprocket 7359, a third sprocket 73511, and a vibration sludge shaking unit. The first sprocket 7357 is fixedly installed at the top of the surface of the driven shaft 7356. The second sprocket 7359 is fixedly installed on the surface of the driven shaft 7356 and is located at the top of the first sprocket 7357. The third sprocket 73511 is fixedly installed at the bottom of the surface of the drive shaft 7351 and is located at the top of the limit bushing 7354. The third sprocket 73511 is in transmission cooperation with the second sprocket 7359 through the drive chain 7358. The first sprocket 7357 on one set of driven shafts 7356 is in transmission cooperation with the second sprocket 7359 on the adjacent set of driven shafts 7356 through the drive chain 7358. The vibration sludge shaking unit is arranged on both sides of the sludge scraping plate 7355 and is used for vibrating and discharging sludge after multiple sets twist and impact each other;
[0053] When the drive shaft 7351 rotates, it drives the second sprocket 7359 on an adjacent set of driven shafts 7356 to rotate through the third sprocket 73511 and the drive chain 7358. After the second sprocket 7359 rotates, it drives the driven shaft 7356 fixed to it to rotate, causing the driven shaft 7356 to drive the sludge scraping plate 7355 at the bottom to rotate and scrape the thickened sludge to the center of the bottom of the thickening tank 7. At the same time, when the driven shaft 7356 rotates, it can drive the second sprocket 7359 on another adjacent set of driven shafts 7356 to rotate through the first sprocket 7357 and the drive chain 7358, thereby realizing the synchronous rotation of multiple sets of driven shafts 7356 to drive the sludge scraping plate 7355 to scrape sludge. And when the sludge scraping plate 7355 twists, the vibration sludge shaking unit prevents sludge from sticking to the surface of the sludge scraping plate 7355, avoiding the formation of large blocks that affect sludge discharge.
[0054] The vibrating mud-shaking unit includes a toggle plate 73551, a resonance spring 73552, an oscillation ball 73553, a torsion shaft 73554, an anti-bending rib 73555 and a reinforcing longitudinal rib 73556. The toggle plate 73551 is fixedly mounted on one side of the torsion shaft 73554. The torsion shaft 73554 is provided with two groups and is symmetrically rotated and mounted on both sides of the mud scraper 73555. The resonance spring 73552 is provided with a plurality of groups and is fixedly mounted on the torsion shaft 73554 at equal distances in the longitudinal direction. One end of 73552 away from the torsion shaft 73554 is fixedly installed with the oscillating ball 73553, one end of half of the oscillating balls 73553 close to the scraper plate 7355 is welded and installed with the scraper plate 7355, and the other half of the oscillating balls 73553 are in contact with the scraper plate 73555. Several groups of anti-bending ribs 73555 are provided and symmetrically fixedly installed longitudinally on the surface of the toggle plate 73551, and the reinforcing longitudinal ribs 73556 are symmetrically fixedly installed on both sides of the top of the scraper plate 73555.
[0055] When the scraper plate 7355 rotates, the toggle plates 73551 on both sides can be driven to rotate. The two adjacent rotating toggle plates 73551 will collide with each other and twist and stagger. Half of the oscillation balls 73553 are fixed to the scraper plate 7355 in a longitudinally staggered manner. After the toggle plates 73551 collide with each other, the resonance spring 73552 can generate a pulling force. The principle is Hooke's law and elastic deformation. Under the action of the pulling force, the toggle plates 73551 are pulled continuously. The elastic swing causes the torsion shaft 73554 to twist and swing, and drives the half of the oscillation ball 73553 that is not fixed to the scraper plate 7355 to swing and hit the surface of the scraper plate 7355, so that the sludge will not hang on the wall under the vibration, and will enter the concentrated mud discharge pipe 701 more smoothly to be discharged. The anti-bending ribs 73555 will reinforce the toggle plate 73551, and the reinforced longitudinal ribs 73556 will reinforce the scraper plate 7355, making it more anti-bending.
[0056] Working principle: Daily inspection stage:
[0057] Thanks to the integrated stainless steel tank body 1 design of the device, the daily inspection work becomes convenient and efficient. The inspection aisle 11 on the top of the tank body and the concentrated area aisle 72 provide convenient passages for inspectors to conduct fault inspections above the thickener 7. The inspectors can quickly visually inspect the thickener 7 and its related components along the aisle. For example, they can directly observe the operation of components such as the speed reduction stirring motor 73, the stirring shaft 732, and the sludge scraping plate 7355 of the self-driven anti-clogging sludge scraping mechanism to check for any loose, deformed, or abnormally worn components. For the flocculation mechanism, the operation status of the stirring motor 102 and the rotation of the stirring rod 103 can be observed, and whether the flocculant inlet 104 is blocked can be checked. At the same time, the integrated design makes the connection parts of each pipeline clearly visible, and the inspectors can quickly check whether there are problems such as leakage and blockage in pipelines such as the first three-way pipe 801, the concentrated sludge pumping pipe 803, and the homogeneous muddy water lifting pipe 807 in the mixing and pumping assembly. This integrated design greatly shortens the inspection path, reduces the inspection time, improves the efficiency of daily maintenance, and ensures that the device is always in good operating condition;
[0058] Sludge water input and flocculation stage:
[0059] The sludge water enters the mixing and flocculation tank 101 from the sludge water input port 4. Inside the mixing and flocculation tank 101, three groups of stirring tanks are equally distributed by partitions, and the stirring motor 102 drives the stirring rod 103 to stir the sludge water in the three groups of stirring tanks respectively;
[0060] The PAC dosing unit 9 adds inorganic polymer coagulant into the mixing and flocculation tank 101, and the stirring mixing cylinder 105 enables the inorganic polymer coagulant and the sludge water not to disperse quickly into the thickener 7 in a short time, so as to flocculate the sludge water efficiently and intensively to form firm and stable flocs;
[0061] The flocculated sludge water overflows into the thickener 7 through the flocculant inlet 104 for subsequent thickening and sedimentation treatment. When there is too much supernatant inside the thickener 7, the fourth butterfly valve in the sewage main pipe 106 is opened, and the turbid sludge water in the middle layer inside the thickener 7 can seep into the foundation 2 of the loop-shaped sludge tank and flow back to the sludge storage tank at the sludge water input port 4 for the next transportation to the mixing and flocculation tank 101 for re-flocculation. Such a design can effectively control the liquid state in the thickener and improve the flocculation treatment efficiency and resource utilization rate;
[0062] Sludge water thickening and sedimentation stage:
[0063] The muddy water entering the concentration tank 7 is concentrated and precipitated under the action of gravity. The supernatant after the separation of mud and water flows into the upper clear water sump 71 and is refluxed through the upper clear water return pipe 5 for utilization; the self-driven anti-blocking scraper mechanism starts to work, the deceleration stirring motor 73 is started, the stirring shaft 732 is driven to rotate, and the stirring frame 734 and the reinforcing rib 733 are driven to twist. When the stirring frame 734 rotates, the driven gear 7352 in the driven driving assembly is meshed with the gear ring 7353, so that the driven gear 7352 rotates, and then drives the driving shaft 7351 to rotate, and drives the scraper blade 7355 to rotate. At the same time, the driving shaft 7351 drives the remaining twelve groups of driven shafts 7356 to rotate synchronously through the first sprocket 7357, the driving chain 7358, the second sprocket 7359 and the third sprocket 73511 in the linkage scraper assembly. The multiple groups of scraper blades 7355 work together to scrape the concentrated sludge to the bottom center of the concentration tank 7, so that it is convenient to be discharged through the concentrated mud discharge pipe 701;
[0064] During the mud scraping process, the vibration mud shaking unit plays a role, the rotation of the mud scraping plate 73555 drives the toggle plates 73551 on both sides to rotate, and the adjacent toggle plates 73551 collide with each other and twist and stagger. Since half of the vibration ball 73553 is fixed to the mud scraping plate 7355, and the other half of the vibration ball 73553 is not fixed to the mud scraping plate 73555, after the toggle plate 73551 collides, the resonance spring 73552 generates tension to make the torsion shaft 73554 twist and swing, driving the unfixed vibration ball 73553 to swing and hit the surface of the mud scraping plate 73555 to prevent the mud from hanging on the wall, ensuring that the mud can enter the concentrated mud discharge pipe 701 more smoothly. The anti-bending ribs 73555 and the reinforced longitudinal ribs 73556 respectively reinforce the toggle plate 73551 and the mud scraping plate 7355, enhance their anti-bending ability, extend their service life, and ensure that the mud scraping work is stable and efficient.
[0065] Concentrated sludge transportation and processing stage:
[0066] The concentrated mud homogenizing and conveying unit can be operated according to the demand. When the concentrated sludge precipitated at the bottom of the concentration tank 7 needs to be conveyed to the balancing tank 6 for homogenization, the first butterfly valve 702 is closed, the second butterfly valve 703 is opened, the fourth screw conveying pump 704 is started, and the concentrated mud discharge pipe 701 conveys the concentrated sludge to the balancing tank 6 through the sludge lifting pipe 705. In the balancing tank 6, the submersible agitator 61 is installed diagonally to stir the mud and water for homogenization;
[0067] When it is necessary to transport the concentrated sludge to the mechanism for concentrating muddy water into cakes for treatment, close the second butterfly valve 703, open the first butterfly valve 702, start the first screw conveyor pump 802 and the third screw conveyor pump 806. The concentrated sludge discharge pipe 701 transports the concentrated sludge to the concentrated sludge suction pipe 803, and then the first screw conveyor pump 802 and the third screw conveyor pump 806 pump the concentrated sludge to the first three-way pipe 801, and then enter the first spiral dewatering device 8 and the second spiral dewatering device 81;
[0068] In the mechanism for concentrating muddy water into cakes, the PAM chemical feeder 91 inputs the polymer into the first spiral dewatering device 8 and the second spiral dewatering device 81 to eliminate the electrostatic repulsion between sludge particles and make them coagulate into larger flocs;
[0069] The first spiral dewatering device 8 and the second spiral dewatering device 81 separate the concentrated sludge from the bottom of the balance tank 6 and the bottom of the thickening tank 7. The separated mud cakes are transported into the external sludge truck hopper through the screw conveyor 82;
[0070] At the same time, the water extruded by the first spiral dewatering device 8 and the second spiral dewatering device 81 is discharged to the balance tank 6 at the bottom. After being evenly mixed with the muddy water transported by the sludge lift pipe 705 from the thickening tank 7, the muddy water separation treatment can be carried out again, improving the utilization rate of water resources, reducing the moisture content of the sludge, and realizing the efficient treatment and disposal of the sludge.
[0071] The overall treatment logic is to first flocculate the input muddy water, then precipitate in the thickening tank 7 and assist in sludge discharge through the self-driven anti-blocking sludge scraping mechanism. Then, according to the need, the concentrated sludge is transported to the balance tank 6 for homogenization or directly dehydrated into cakes. Each unit in the whole process is closely integrated and works together in the integrated stainless steel tank body 1. It not only realizes the integrated and efficient treatment of sludge from input to treatment and discharge of mud cakes, improves the treatment efficiency, reduces the operation cost, and reduces environmental pollution, but also brings great convenience to daily inspection and maintenance through the integrated design, ensuring the stable and reliable operation of the device.
