Description

Technical Field

[0001] The present invention relates to the field of sludge treatment, and more specifically, to a continuous sludge thermal decomposition device. Background Art

[0002] During highway construction, a large amount of sewage is generated, and sludge is produced after the sewage is treated. The sludge contains a large amount of organic matter, heavy metals, pathogens, etc. If not properly treated, it will cause serious pollution to the environment.

[0003] Traditional sludge treatment methods mainly include landfill, incineration, composting, etc. These methods have problems such as large land occupation, high treatment cost, and easy generation of secondary pollution. Sludge thermal decomposition technology is a new type of sludge treatment technology, which can convert the organic matter in sludge into combustible gas, tar, carbon and other products, realizing the reduction, harmlessness and resource utilization of sludge.

[0004] However, for the sludge generated during highway construction, generally, a sludge suction pipe and a sludge suction pump are used in cooperation to suck the sludge into the interior of the decomposition device for treatment. During the sludge suction process, a large amount of impurities will be adsorbed, such as stones, cement blocks, broken bricks, etc. A large amount of solid matter entering the interior of the device is likely to cause blockage of the interior of the device and reduce the service life of the device.

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figures 1 to 10 , a continuous sludge thermal decomposition device, including a dehydration bin 1. A third driving motor 7 is fixedly connected to the edge of the upper surface of the dehydration bin 1. The output end of the third driving motor 7 is fixedly connected to a second gear 9. A centrifugal cylinder 8 is rotatably connected to the middle of the inner bottom of the dehydration bin 1. A second annular rack 11 is fixedly connected to the outer surface of the centrifugal cylinder 8. The bottom of the centrifugal cylinder 8 is connected to a sand pump 10 through a rotary joint. A carbonization heating component 5 is fixedly connected to the bottom of the dehydration bin 1. A drainage component is arranged at the edge of the inner bottom of the dehydration bin 1. A mud suction component 6 for adsorbing sludge is connected to the outer surface of the dehydration bin 1.

[0043] Such as Figure 2 , Figure 4 , Figure 5 And Figure 6As shown in the figure, the sludge suction assembly 6 includes a sludge suction pump 61 fixed on the outer surface of the dehydration bin 1. The output end and the input end of the sludge suction pump 61 are respectively connected with a sludge pipe 62 and a connecting hose 63. The other end of the connecting hose 63 is connected with a hand-held cylinder 64. The bottom of the hand-held cylinder 64 is fixedly connected with a sludge cover 65. The inner bottom of the sludge cover 65 is fixedly connected with a circular plate 611. A plurality of mud inlet holes 612 are formed inside the circular plate 611. The upper surface of the circular plate 611 penetrates and rotatably connects with a rotating shaft 613. The top of the rotating shaft 613 is fixedly connected with a second worm gear 610. The outer surface of the rotating shaft 613 is fixedly connected with a rotating rod 614 near the bottom. The outer surface of the sludge cover 65 is fixedly connected with a second driving motor 66. The output end of the second driving motor 66 is fixedly connected with a second worm 69.

[0044] One end of the second worm 69 extends into the sludge cover 65 and meshes with the second worm gear 610. The rotating rod 614 is located below the circular plate 611 and is in close contact with the circular plate 611. A flange is connected to the outer surface of the sludge cover 65 near the bottom. An adjusting assembly 67 is connected to the edge of the upper surface of the sludge cover 65. A cleaning assembly 68 is connected to the edge of the inner top of the sludge cover 65.

[0045] The drainage component includes a drainage trough 2 fixed at the inner bottom edge of the dehydration bin 1 and a water collection tank 3 connected to the carbonization heating assembly 5. The bottom of the drainage trough 2 communicates with two diversion pipes 4. The other ends of the diversion pipes 4 extend into the water collection tank 3.

[0046] Turn on the sludge suction pump 61 to work. Hold the hand-held cylinder 64 and transport the sludge cover 65 to the sludge. Through the suction of the sludge suction pump 61, the sludge enters the inside of the sludge cover 65 through the mud inlet holes 612. The sludge then enters the inside of the dehydration bin 1 through the sludge cover 65, the hand-held cylinder 64 and the sludge suction pump 61 and falls into the inside of the centrifugal cylinder 8. The third driving motor 7 works to drive the second gear 9 to rotate. The second gear 9 drives the centrifugal cylinder 8 to rotate at a high speed through the second annular rack 11, so that the centrifugal cylinder 8 centrifuges the sludge inside it, dehydrates the sludge, and the water is thrown out of the inside of the centrifugal cylinder 8 and enters the drainage trough 2, and is discharged into the water collection tank 3 through the diversion pipe 4 for collection.

[0047] When sucking mud, the second drive motor 66 is simultaneously turned on to drive the second worm 69 to rotate. The second worm 69 drives the second worm gear 610 and the rotating shaft 613 to rotate. The rotating shaft 613 drives two rotating rods 614 to rotate. When there are leaves, plastic bags, and some stones adsorbed on the surface of the circular plate 611 inside the mud inlet hole 612, the rotating rotating rods 614 can clean the surface of the circular plate 611, sweep the sundries off the surface of the circular plate 611, keep the mud inlet hole 612 unblocked, ensure the continuous unblocking during mud suction, avoid blockage caused by sundries during mud suction, and effectively block some water-insoluble solids through the circular plate 611 to prevent the solids from entering the interior of the device and causing blockage and subsequent difficult-to-handle situations.

[0048] As Figure 6 shown, the adjusting assembly 67 includes an internally threaded sleeve plate 674 fixed at the edge of the upper surface of the sludge cover 65. A threaded rod 671 is threadedly connected inside the internally threaded sleeve plate 674. The bottom of the threaded rod 671 is connected to a circular ring 672 through a bearing. The bottom of the circular ring 672 is uniformly and fixedly connected with support legs 673.

[0049] A circular contact plate is provided at the bottom of the support leg 673. The bottom of the support leg 673 penetrates through the flange of the sludge cover 65 and slides therewith.

[0050] However, during the process of sucking mud, it is necessary to ensure that there is a certain distance between the bottom of the sludge cover 65 and the ground to ensure that the sludge can enter the interior of the sludge cover 65. However, the staff needs to hold the hand-held cylinder 64 at a certain height for a long time, which will increase the fatigue of the staff over time and result in low work efficiency.

[0051] At this time, by rotating the threaded rod 671 under the action of the thread inside the internally threaded sleeve plate 674, the threaded rod 671 moves downward, driving the entire circular ring 672 to move downward. The circular ring 672 drives the four support legs 673 to slide downward inside the flange of the sludge cover 65 and gradually come into contact with the ground, forming a supporting effect on the sludge cover 65. At this time, the staff does not need to hold the hand-held cylinder 64 in the same posture, greatly improving the comfort of the staff and effectively reducing the fatigue of the staff. At the same time, as the water level drops, the support legs 673 can slide upward, and the sludge cover 65 gradually moves downward close to the ground, so that the bottom of the sludge cover 65 is always inside the sludge, avoiding the empty suction of the sludge cover 65 above the water level of the sludge.

[0052] As Figure 2 、 Figure 7 and Figure 8As shown in the figure, the cleaning component 68 includes an annular water pipe 683 fixed to the top inside the sludge hood 65, a second servo motor 681 fixed to the outer surface of the sludge hood 65 near the top, and a water inlet hose 689 fixed to one side of the water collection tank 3. The output end of the water inlet hose 689 is fixedly connected to a water pump 688. The output end of the second servo motor 681 is fixedly connected to a first gear 682. A plurality of water outlet holes 685 are formed on the inner surface of the annular water pipe 683. An annular baffle 684 is slidably sleeved on the outer surface of the annular water pipe 683. A plurality of through holes 686 are formed on the inner surface of the annular baffle 684. A first annular rack 687 is fixedly connected to the outer surface of the annular baffle 684. The first annular rack 687 meshes with the first gear 682. The other end of the water pump 688 is communicated with the annular water pipe 683.

[0053] The number of the water outlet holes 685 is the same as that of the through holes 686, and the water outlet holes 685 correspond to the through holes 686 one by one. Rubber rings are fixedly connected to both sides of the inner surface of the annular baffle 684. The cross section of the annular baffle 684 is arc-shaped and fits with the annular water pipe 683.

[0054] After the sludge hood 65 is used, if the round plate 611 and the mud inlet hole 612 are not cleaned in time, once the sludge on the surfaces of the round plate 611 and the mud inlet hole 612 dries, it is very easy to block the mud inlet hole 612, and it is necessary to clean the mud inlet hole 612 one by one, which delays the working time.

[0055] After the sludge is absorbed, at this time, the water inlet hose 689 is opened to transport the clear water inside the water collection tank 3 to the inside of the annular water pipe 683 through the water pump 688. The water inside the annular water pipe 683 is sprayed out through a plurality of water outlet holes 685. The water sprayed out from the water outlet holes 685 can wash the round plate 611 and the mud inlet hole 612, and can quickly wash the sludge inside the mud inlet hole 612, effectively preventing the sludge remaining inside the mud inlet hole 612 from blocking the mud inlet hole 612 after drying, avoiding the dredging work of the mud inlet hole 612, and using the water separated from the sludge to clean the mud inlet hole 612 and the round plate 611, saving water resources;

[0056] When the annular water pipe 683 is idle, the second servo motor 681 drives the first gear 682 to rotate. The first gear 682 drives the first annular rack 687 to rotate. The first annular rack 687 drives the annular baffle 684 to slide on the surface of the annular water pipe 683. The annular baffle 684 drives the through holes 686 to move away from the water outlet holes 685, so that the water outlet holes 685 and the through holes 686 are staggered from each other, sealing the water outlet holes 685, and preventing sludge from entering the inside of the annular water pipe 683 during mud suction, improving the practicability of the equipment.

[0057] Such as Figure 9 and Figure 10As shown, the carbonization heating assembly 5 includes a carbonization bin 51 fixed at the bottom of the dehydration bin 1, a fixed grid plate 53 is fixedly connected to the inner surface of the carbonization bin 51, a first drive motor 52 is fixedly connected to one side of the outer surface of the carbonization bin 51, a first worm 57 is fixedly connected to the output end of the first drive motor 52, a movable grid plate 54 is slidably connected to the edge of the lower surface of the fixed grid plate 53, an elliptical slide rail 55 is fixedly connected to the lower surface of the movable grid plate 54, and a mounting shaft 510 is rotatably connected to the bottom of the carbonization bin 51. A first worm gear 58 is fixedly connected to the middle of the outer surface of the mounting shaft 510, a mounting shaft 510 is fixedly connected to the top of the outer surface of the mounting shaft 510, a cloth assembly 59 is connected to the outer surface of the mounting shaft 510 between the first worm gear 58 and the L-shaped rod 56, the first worm 57 is meshed with the first worm gear 58, the other end of the sludge pump 10 extends to the interior of the carbonization bin 51, the L-shaped rod 56 is located below the elliptical slide rail 55, and the vertical portion of the L-shaped rod 56 extends to the interior of the elliptical slide rail 55.

[0058] After the centrifugal drum 8 rationally dehydrates the sludge, a large amount of sludge remains inside the centrifugal drum 8. At this time, the first drive motor 52 is turned on to drive the first worm 57 to rotate. The first worm 57 drives the installation shaft 510 to rotate through the first worm gear 58. The installation shaft 510 drives the L-shaped rod 56 to rotate inside the elliptical slide rail 55. Since the L-shaped rod 56 rotates in a circular motion, and the motion radius is consistent with the distance from the nearest end of the elliptical slide rail 55 to the center of the installation shaft 510, the L-shaped rod 56 will drive the L-shaped rod 56 to rotate left and right. The movable grid plate 54 is swung back and forth to the right, thereby driving the movable grid plate 54 to move back and forth, and the grid plates on the movable grid plate 54 and the grid plates on the fixed grid plate 53 are constantly staggered and overlapped. At this time, the mud residue in the centrifugal cylinder 8 is transported to the interior of the carbonization bin 51 through the sludge pump 10. When the mud residue passes through the movable grid plate 54 and enters the interior of the fixed grid plate 53, it will be squeezed and hit by the moving fixed grid plate 53, and the large pieces of mud residue will be hit into small particles, which can effectively make the subsequent decomposition more thorough, shorter in time, more efficient, and reduce the loss of resources.

[0059] like Figure 10 As shown, the cloth assembly 59 includes two stirring shafts 591 fixed on the outer surface of the mounting shaft 510 near the bottom, and the outer surface of the mounting shaft 510 is fixedly connected with a first fan-shaped guide plate 592, a second fan-shaped guide plate 593, a third fan-shaped guide plate 594 and a fourth fan-shaped guide plate 595 in sequence.

[0060] The first fan-shaped flow guide plate 592 , the second fan-shaped flow guide plate 593 , the third fan-shaped flow guide plate 594 and the fourth fan-shaped flow guide plate 595 have different diameters, and the stirring shaft 591 is in contact with the bottom of the carbonization bin 51 .

[0061] However, the fallen mud residue always forms a mud pile in the middle of the bottom inside the carbonization bin 51, causing the mud inside the mud pile to not be sufficiently heated and decomposed, and the decomposition is not thorough enough;

[0062] At this time, when the installation shaft 510 rotates, it simultaneously drives the first sector-shaped deflector 592, the second sector-shaped deflector 593, the third sector-shaped deflector 594, and the fourth sector-shaped deflector 595 to rotate. The mud will first fall on the first sector-shaped deflector 592, the second sector-shaped deflector 593, the third sector-shaped deflector 594, and the fourth sector-shaped deflector 595. Since the diameters of the first sector-shaped deflector 592, the second sector-shaped deflector 593, the third sector-shaped deflector 594, and the fourth sector-shaped deflector 595 are different, the positions where the mud falls from their surfaces are different, and the mud can be thrown to different positions at the bottom of the carbonization bin 51, so that the mud is spread as flat as possible on the bottom inside the carbonization bin 51, enabling the mud to be fully heated and decomposed and carbonized, further improving the decomposition efficiency. At the same time, the stirring shaft 591 stirs the mud to ensure that the temperature of each area of the mud is consistent and avoid incomplete decomposition in some areas.

[0063] Usage method: First, the sludge can be sucked into the interior of the device through the mud suction assembly 6. By rotating the rotating rod 614 on the surface of the circular plate 611, impurities can be cleaned from the surface of the circular plate 611 to avoid clogging the mud inlet hole 612. At the same time, the adjustment assembly 67 can support the mud hood 65, reducing the need for manual holding of the hand-held cylinder 64 in a single position for a long time. The cleaning assembly 68 can clean the circular plate 611 and the mud inlet hole 612 after the mud suction is completed, preventing the remaining sludge in the mud inlet hole 612 from drying and clogging the mud inlet hole 612;

[0064] The carbonization heating assembly 5 can break up the dehydrated mud blocks into small particles, enabling the mud to be fully heated. The cloth distribution assembly 59 can evenly throw the fallen mud to various areas of the carbonization bin 51, preventing the mud from forming a mud pile inside the carbonization bin 51 and avoiding incomplete heating and carbonization of the internal mud.

[0065] The above is only a preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
