Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, and in particular to an integrated concentrated sludge treatment device. Background Art

[0002] In the past, sludge treatment often required multiple independent treatment units to operate in sequence. In the concentration stage, gravity thickening tanks are often used, which occupy a large area and have low concentration efficiency. A long residence time is required to initially reduce the volume of sludge. In the subsequent dehydration process, whether it is a belt filter press, a plate and frame filter press or a centrifugal dehydrator, it is necessary to equip the corresponding dosing system, flushing system and other auxiliary facilities. The connection and coordination between the various equipments have high technical requirements for the operators. If you are not careful, it is easy to fail, affecting the smoothness of the overall treatment process. The traditional sludge treatment process involves a variety of equipment, and each equipment needs to occupy a certain space. For example, the gravity thickening tank requires a large plane area to achieve the sedimentation and concentration of the sludge; various dehydration equipment also requires a spacious site to place the equipment body and related supporting facilities. For cities with increasingly tight land resources, especially sewage treatment plants in central urban areas, this is undoubtedly a heavy burden, which not only increases the construction cost, but also limits the further expansion of the treatment scale.

[0003] In order to overcome the various drawbacks of traditional sludge treatment methods and meet the growing demand for environmental protection, the development of an integrated concentrated sludge treatment device has become an inevitable trend in the development of the industry. This integrated device is designed to integrate multiple treatment links such as sludge concentration and dehydration into a compact equipment unit. Through optimized design and innovative processes, it achieves the goals of high efficiency, energy saving, environmental protection and small footprint of sludge treatment, providing modern sewage treatment plants with more reliable, economical and convenient sludge treatment solutions.

[0049] The aisle 72 in the concentration area is convenient for the inspection personnel to perform fault inspection above the concentration tank 7, and the reduction stirring motor 73 can drive the stirring shaft 732 to rotate after starting, and the stirring frame 734 and the reinforcement rib 733 are driven to twist through the stirring shaft 732, and during the twisting process, the scraper plate 7355 and the driven shaft 7356 are driven to rotate through the driven drive assembly, so that the scraper plate 7355 scrapes the bottom of the concentration tank 7, and scrapes the concentrated sludge to the center of the bottom of the concentration tank 7 for easy discharge. At the same time, the rotating scraper plate 7355 can prevent the concentrated sludge from gradually accumulating into a huge mud mass and then being difficult to push and scrape, thereby increasing the mud discharge speed and preventing the existing scraping place from being stationary. The limiting shaft sleeve 7354 can limit the rotation of several driven shafts 7356, and the limiting 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 gear ring 7353. The drive shaft 7351 is provided with two groups and symmetrically distributed on both sides of the stirring shaft 732, and the bottom is rotatably mounted with the limiting sleeve 7354, and the top is rotatably mounted with the limiting mounting plate 735. The driven gear 7352 is fixedly mounted on the top of the drive shaft 7351 and meshed with the gear ring 7353. The gear ring 7353 is fixedly mounted on the inner wall of the concentration tank 7 and located at the top of the stirring frame 734. The top of the scraper 7355 is fixedly mounted with the bottom of the drive shaft 7351.

[0051] The gear ring 7353 can make the rotating stirring frame 734 mesh with the gear ring 7353 through the driven gear 7352, so that the driven gear 7352 can rotate. After the rotation, the driven gear 7352 drives the driving shaft 7351 to rotate. The driving shaft 7351 rotates and drives the scraper plate 7355 at the bottom to rotate. When the driving shaft 7351 rotates, it drives the remaining twelve groups of driven shafts 7356 to rotate through the linked scraping assembly, and drives the scraper plate 7355 to scrape the mud.

[0052] The linked mud scraping assembly includes a first sprocket 7357, a driving chain 7358, a second sprocket 7359, a third sprocket 73511 and a vibrating mud shaking unit. The first sprocket 7357 is fixedly mounted on the top of the surface of the driven shaft 7356, the second sprocket 7359 is fixedly mounted on the surface of the driven shaft 7356 and is located on the top of the first sprocket 7357, the third sprocket 73511 is fixedly mounted on the bottom of the surface of the driving shaft 7351 and is located on the top of the limiting sleeve 7354, the third sprocket 73511 is driven and matched with the second sprocket 7359 through the driving chain 7358, the first sprocket 7357 on one group of driven shafts 7356 and the second sprocket 7359 on an adjacent group of driven shafts 7356 are driven and matched through the driving chain 7358, and the vibrating mud shaking unit is arranged on both sides of the mud scraping plate 7355, and is used for vibrating and discharging mud after multiple groups of mutual twisting and collision;

[0053] When the driving shaft 7351 rotates, the third sprocket 73511 cooperates with the driving chain 7358 to drive the second sprocket 7359 on an adjacent group of driven shafts 7356 to rotate. After the second sprocket 7359 rotates, it drives the driven shaft 7356 fixed thereto to rotate, so that the driven shaft 7356 drives the scraper plate 7355 at the bottom to rotate and scrape the concentrated sludge to the bottom center of the thickening tank 7. At the same time, when the driven shaft 7356 rotates, the first sprocket 7357 cooperates with the driving chain 7358 to drive the second sprocket 7359 on another group of adjacent driven shafts 7356 to rotate, thereby realizing the synchronous rotation of multiple groups of driven shafts 7356 to drive the scraper plate 7355 to scrape the mud, and when the scraper plate 7355 is twisted, the mud shaking unit is vibrated to prevent sludge from hanging on the surface of the scraper plate 7355, so as to avoid the formation of large lumps that affect mud 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 one-piece stainless steel tank body 1 design of the device, daily inspection work becomes convenient and efficient. The inspection aisle 11 on the top of the tank body and the aisle 72 in the concentration area provide convenient passages for inspectors to conduct fault inspections above the concentration tank 7. Inspectors can quickly conduct visual inspections of the concentration tank 7 and its related components along the aisles. For example, they can directly observe the operation of the reduction stirring motor 73, stirring shaft 732, scraper blade 7355 and other components of the self-driven anti-blocking scraper mechanism to check whether there are any loose, deformed or abnormally worn parts. For the flocculation mechanism, By observing the running status of the stirring motor 102 and the rotation of the stirring rod 103, it is possible to check whether the flocculant inlet 104 is blocked, etc. At the same time, the integrated design makes the connection parts of each pipeline clearly visible, and the inspection personnel can quickly check whether there are leaks, blockages and other problems in the first three-way pipe 801, the concentrated mud pumping pipe 803, the homogenized mud water lifting pipe 807 and other pipelines 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] Mud and water input and flocculation stage:

[0059] The muddy water enters the mixing and flocculation tank 101 from the muddy water input port 4. The interior of the mixing and flocculation tank 101 is divided into three groups of stirring tanks at equal distances by partitions. The stirring motor 102 drives the stirring rod 103 to stir the muddy water in the three groups of stirring tanks respectively.

[0060] The PAC dosing unit 9 adds an inorganic polymer coagulant to the mixing flocculation tank 101, and the mixing drum 105 is stirred so that the inorganic polymer coagulant and the muddy water will not quickly disperse to the concentration tank 7 in a short time, thereby flocculating the muddy water in a concentrated and efficient manner to form a strong and stable floc.

[0061] The flocculated muddy water overflows into the concentration tank 7 through the flocculation liquid infiltration port 104 for subsequent concentration and sedimentation treatment. When there is too much supernatant in the concentration tank 7, the fourth butterfly valve in the sewage main pipe 106 is opened, and the turbid muddy water in the middle layer of the concentration tank 7 can infiltrate into the circular sludge tank foundation 2 and flow back to the sludge storage tank of the muddy water input port 4, so as to be transported to the mixed flocculation tank 101 for flocculation again next time. Such a design can effectively control the liquid state in the concentration tank and improve the flocculation treatment efficiency and resource utilization rate.

[0062] Mud and water concentration 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 the concentrated sludge needs to be transported to the mud-water concentrating cake mechanism for treatment, the second butterfly valve 703 is closed, the first butterfly valve 702 is opened, the first screw conveying pump 802 and the third screw conveying pump 806 are started, and the concentrated sludge discharge pipe 701 conveys the concentrated sludge to the concentrated sludge pumping pipe 803, and then the concentrated sludge is pumped to the first three-way pipe 801 through the first screw conveying pump 802 and the third screw conveying pump 806, and then enters the first screw stacking dehydration device 8 and the second screw stacking dehydration device 81;

[0068] In the mud-water concentration into cake mechanism, the PAM drug-infusing machine 91 inputs high molecular polymer into the first screw stack dewatering device 8 and the second screw stack dewatering device 81 to eliminate the electrostatic repulsion between the sludge particles and make them condense into larger flocs;

[0069] The first screw stack dewatering device 8 and the second screw stack dewatering device 81 separate the concentrated mud from the bottom of the balancing tank 6 and the bottom of the thickening tank 7, and the separated mud cake is transported to the external sludge bucket through the screw conveyor 82;

[0070] At the same time, the water squeezed out by the first screw stack dehydration device 8 and the second screw stack dehydration device 81 is discharged to the balancing tank 6 at the bottom, and after being homogeneously mixed with the mud and water transported from the concentration tank 7 through the sludge lifting pipe 705, the mud and water separation treatment can be carried out again to improve the utilization rate of water resources, reduce the water content of sludge, and realize efficient treatment and disposal of sludge.

[0071] The overall processing logic is to first flocculate the input muddy water, then settle it in the concentration tank 7 and assist in sludge discharge through a self-driven anti-blocking sludge scraper mechanism, and then transport the concentrated sludge to the balance tank 6 for homogenization or directly dehydrate it into cakes as needed. The various units of the whole process are tightly integrated in the one-piece stainless steel tank body 1 and work together, which not only realizes the integrated and efficient treatment of sludge from input to treatment into mud cakes and discharge, improves the processing efficiency, reduces operating costs, and reduces pollution to the environment, but also brings great convenience to daily inspection and maintenance through integrated design, ensuring the stable and reliable operation of the device.
