Description

Technical Field

[0001] The present invention relates to the technical field of waste incineration fly ash filtration and centralized treatment equipment, and particularly relates to a waste incineration fly ash filtration and centralized treatment equipment. Background Art

[0002] Fly ash filtration is a technology used to remove fly ash particles from gases, commonly found in fields such as coal gasification and waste incineration.

[0003] During the waste incineration process, the organic matter in the waste is mainly discharged in the form of gaseous substances, while the inorganic matter mainly forms solid particles. Among them, the larger solid particles are deposited at the bottom of the incinerator and on the grates, and the finer particles float in the flue gas and enter the flue together with the flue gas to reach the filtration device, where they are captured by the filtration device.

[0004] However, existing dust collectors (such as electrostatic precipitators and bag filters) capture the fine particles in the flue gas, but there will still be a small part of the fine particles entering the air, thus polluting the atmosphere and endangering people's physical health. Moreover, when cleaning or replacing the filtration device, the incineration work needs to be stopped to clean or replace the filtration device, resulting in low work efficiency.

[0005] Therefore, we provide a waste incineration fly ash filtration and centralized treatment equipment. Summary of the Invention

[0011] Preferably, a limiting groove is formed on one side of the inner wall of the annular groove. Opposite sides of the inner wall of the limiting groove are fixedly installed with torsion shafts. A torsion spring is inserted on the outer side of the torsion shaft, and a limiting plate is inserted on the outer side of the torsion spring.

[0012] Preferably, the screw rod is fixedly connected to a one-way bearing. One end of the one-way bearing away from the screw rod is fixedly connected to a connecting shaft.

[0016] Preferably, a gas flue is fixedly installed at the lower half of the outside of the filtering bin. The outlet of the gas flue is located on one side of the first fan group and the second fan group.

[0017] Compared with the prior art, the present invention provides a garbage incineration fly ash filtering and centralized treatment device, which has the following beneficial effects:

[0018] 1. In the present invention, by setting the flue outlet on one side of the first fan group to be smaller than the flue outlet of the second fan group, when the second fan group is connected to the filter plate and its weight is greater than the rotation load of the first fan group, it can ensure that the second fan group rotates at the same speed as the first fan group, ensuring the normal rotation and filtering of the filter plate, thereby improving the filtering effect of the garbage incineration fly ash filtering and centralized treatment device.

[0019] 2. In the present invention, by setting the rotation directions of the first fan group and the second fan group to be the same, it can ensure that when the first fan group drives the screw rod to rotate, the rotation at the same speed of the second fan group can make up for the position difference of the threaded rotation and rising, enabling the second fan group to maintain the original position rotation and not move upward due to the rotation of the screw rod, resulting in the filter plate moving out of the water prematurely, thereby improving the filtering effect of the garbage incineration fly ash filtering and centralized treatment device.

[0020] 3. In the present invention, by providing the insertion posts and insertion holes, the second fan group can drive the support column to rotate, and at the same time drive the filter plate to rotate for filtration, thereby improving the filtration effect of the garbage incineration fly ash filtration and centralized treatment equipment. At the same time, when installing a new support column, through the relative movement of the two, the insertion post can accurately enter the insertion hole without the need for manual intervention in the steps of prior positioning and installation, thereby improving the working efficiency of the garbage incineration fly ash filtration and centralized treatment equipment. And through the insertion connection method, the filter plate can be quickly removed and installed, saving the complex steps of stopping garbage incineration and then replacing the filtration device, thereby further improving the working efficiency of the garbage incineration fly ash filtration and centralized treatment equipment.

[0021] 4. In the present invention, by providing the sliding shaft, the second fan group can maintain vertical rotation and drive the filter plate to operate normally. At the same time, when it is necessary to move the second fan group downward, the second fan group can be stopped from rotating through the limiting device, so that it can move downward to the initial position to ensure the normal operation of the new filter plate, thereby improving the filtration effect and working efficiency of the garbage incineration fly ash filtration and centralized treatment equipment.

[0022] 5. In the present invention, by providing the baffle plate, it can be driven by the flowing water to stir up the fly ash deposited at the lower end of the inner wall of the filtration chamber, so that it floats into the rotating filter plate, ensuring that the fly ash in the filtration chamber can be fully filtered by the filter plate, and at the same time avoiding the complex steps of fly ash depositing in the filtration chamber to generate sludge and requiring regular stopping of garbage incineration and then cleaning, thereby further improving the filtration effect and working efficiency of the garbage incineration fly ash filtration and centralized treatment equipment.

[0023] The parts not involved in this device are the same as or can be implemented by the prior art. The structure of the present invention is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] 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 of the embodiments.

[0037] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0038] Embodiment: A garbage incineration fly ash filtration and centralized treatment device, as Figure 1 - Figure 11 shown, includes a filtration bin 1. Inside the filtration bin 1, a first fan group 6 is provided. A screw rod 5 is fixedly installed on the outer side of the middle of the first fan group 6. The screw rod 5 is threadedly connected to a second fan group 7. An insertion cavity 15 is opened at the upper end of the second fan group 7. A plug post 14 is fixedly installed at the lower end of the inner wall of the insertion cavity 15. A support column 9 is inserted into the insertion cavity 15. An insertion hole 33 is opened at the lower end of the support column 9. The insertion hole 33 is inserted into the plug post 14. A filter plate 4 is fixedly installed on the outer side of the support column 9. The support column 9 is inserted into the screw rod 5.

[0039] When the heat flow of combustion and fly ash rush into the interior of the filter chamber 1 through the flue, the heat flow and fly ash enter the water in the filter chamber 1, and at the same time, the first fan group 6 and the second fan group 7 are blown. At this time, the first fan group 6 starts to rotate. The first fan group 6 drives the screw rod 5, and the screw rod 5 starts to rotate following the first fan group 6. At the same time, the second fan group 7 starts to rotate. At this time, the thread on the screw rod 5 reaches the second fan group 7. The rotation direction of the second fan group 7 is the same as that of the first fan group 6. The insertion column 14 in the insertion cavity 15 at the upper end of the second fan group 7 starts to rotate following it. At this time, the insertion column 14 drives the support column 9 to start rotating through the insertion hole 33. At the same time, the support column 9 drives the filter plate 4 to start rotating. At this time, the fly ash that rushes into the water through the flue floats in the water, and the heat flow moves upward through the water to reach the outside of the filter chamber 1. The rotating filter plate 4 contacts the fly ash in the water. At this time, the water passes through the filter plate 4, and the fly ash is filtered onto the filter plate 4. At this time, the filter plate 4 continues to rotate following the support column 9. When the fly ash filtered on the filter plate 4 gradually increases, the overall weight of the filter plate 4 starts to slowly and gradually increase. At the same time, the weight of the support column 9 starts to slowly and gradually increase. The weight is transmitted to the second fan group 7 through the support column 9. At this time, the heat flow that continues to rush into the water will continue to push the second fan group 7. Due to the slowly and gradually increasing weight of the second fan group 7, the force of the heat flow pushing gradually starts to be unable to drive its rotation. At the same time, the rotation speed of the second fan group 7 starts to gradually and slowly decrease. When the rotation speed of the second fan group 7 starts to decrease, the first fan group 6 still continues to rotate at the original speed. At this time, the rotation speed of the screw rod 5 will be higher than that of the second fan group 7. The second fan group 7 starts to slowly and gradually move upward on the screw rod 5. At the same time, the second fan group 7 drives the support column 9 to slowly and gradually move upward. At this time, the second fan group 7 starts to slowly and gradually move away from the flue outlet. The rotation speed of the second fan group 7 starts to further gradually decrease and continues to move upward. When the incoming heat flow cannot blow to the second fan group 7, the second fan group 7 stops rotating and continues to move upward. When the second fan group 7 moves to the end of the upper thread of the screw rod 5, the continuously rotating screw rod 5 cannot rotate the second fan group 7 upward anymore. At this time, the second fan group 7 is in an inserted state with the upper end of the screw rod 5 and stops moving upward. At this time, the filter plate 4 is driven by the support column 9 to be taken out of the filter chamber 1. At the same time, a new support column 9 is inserted on the screw rod 5. At this time, the lower end of the support column 9 is inserted into the insertion cavity 15. At this time, driven by the motor, the screw rod 5 starts to rotate in the reverse direction. At this time, the second fan group 7 starts to move downward, and at the same time, the support column 9 starts to move downward. When the second fan group 7 moves to the initial position, the motor operation is stopped at this time. At this time, the second fan group 7 starts to rotate under the blowing of the heat flow. At this time, the insertion cavity 15 and the support column 9 are in a relative rotating state. The support column 9 slides inside the insertion cavity 15. At the same time, the insertion column 14 starts to rotate following the second fan group 7, and the insertion column 14 contacts and slides with the lower end of the support column 9. When the insertion column 14 slides to the insertion hole 33, the insertion column 14 enters the insertion hole 33. At this time, the support column 9 continues to rotate following the second fan group 7, and at the same time, the filter plate 4 starts to rotate.At this time, the work of filtering the fly ash and replacing the filter plate 4 is completed. By setting the flue outlet on one side of the first fan group 6 to be smaller than that of the second fan group 7, it can ensure that the second fan group 7 rotates at the same speed as the first fan group 6, ensuring the normal rotation and filtration of the filter plate 4, thereby improving the filtration effect of the garbage incineration fly ash filtration and centralized treatment equipment. By setting the rotation directions of the first fan group 6 and the second fan group 7 to be the same, it can ensure that when the first fan group 6 drives the screw 5 to rotate, the second fan group 7 can maintain its original position and rotate without being rotated by the screw 5 to move upward, causing the filter plate 4 to move outside the water, thereby improving the filtration effect of the garbage incineration fly ash filtration and centralized treatment equipment. By setting the insertion column 14 and the insertion hole 33, the second fan group 7 can drive the support column 9 to rotate and at the same time drive the filter plate 4 to rotate for filtration, thereby improving the filtration effect of the garbage incineration fly ash filtration and centralized treatment equipment. At the same time, when installing a new support column 9, accurate positioning can be carried out without the need for manual intervention for installation, thereby improving the working efficiency of the garbage incineration fly ash filtration and centralized treatment equipment.

[0040] As Figure 1 - Figure 11 shown, vertical grooves 12 are formed in the inner wall of the filtration chamber 1, walking grooves 13 are formed on opposite sides of the vertical grooves 12, a support shaft 11 is slidably connected to the walking grooves 13, and a support plate 10 is rotatably connected to the support shaft 11. There are several support plates 10, and they are symmetrically distributed.

[0041] An annular groove 20 is formed on the outer side of the lower half of the second fan group 7, sliding grooves 21 are formed on opposite sides of the inner wall of the annular groove 20, and a sliding shaft 23 is slidably connected to the sliding grooves 21.

[0042] A fixing block 24 is fixedly installed on the outer side of the sliding shaft 23, a rotating shaft 25 is rotatably connected to the fixing block 24, and the rotating shaft 25 is rotatably connected to the support plate 10.

[0043] A limiting groove 22 is formed on one side of the inner wall of the annular groove 20, torsion shafts 27 are fixedly installed on opposite sides of the inner wall of the limiting groove 22, a torsion spring 28 is inserted on the outer side of the torsion shaft 27, and a limiting plate 26 is inserted on the outer side of the torsion spring 28.

[0044] When the second fan group 7 is blown by the heat flow, the second fan group 7 starts to rotate. At this time, under the support of the support plate 10 and the fixed block 24, the sliding shaft 23 starts to slide in the sliding groove 21 on the annular groove 20. When the sliding shaft 23 slides to the limiting plate 26 on the sliding groove 21, at this time, the sliding shaft 23 applies a thrust to the limiting plate 26. At this time, the limiting plate 26 starts to rotate into the limiting groove 22 under the support of the torsion shaft 27. At this time, the torsion spring 28 makes a torsion action. When the limiting plate 26 is pushed into the limiting groove 22, the sliding shaft 23 passes through it. At this time, the limiting plate 26 loses the thrust, and the torsion spring 28 loses the thrust and starts to rotate to the initial state. At the same time, under the push of the torsion spring 28, the limiting plate 26 starts to rotate out of the limiting groove 22 under the support of the torsion shaft 27. When the torsion spring 28 returns to the initial state, the limiting plate 26 rotates to the initial state. At this time, the second fan group 7 continues to rotate. When the second fan group 7 starts to move upward, the second fan group 7 applies a pulling force to the sliding shaft 23. At this time, the sliding shaft 23 applies a pulling force to the support plate 10 through the fixed block 24. At the same time, the other end of the support plate 10 applies a pulling force to the support shaft 11. At this time, the support shaft 11 starts to slide upward in the walking groove 13 opened on the vertical groove 12 on the inner wall of the filter bin 1. When the screw 5 starts to rotate in the reverse direction, the second fan group 7 starts to move downward and starts to rotate following the screw 5 at the same time. At this time, the sliding shaft 23 starts to slide in the reverse direction in the sliding groove 21 on the annular groove 20. At this time, the sliding shaft 23 contacts the limiting plate 26, and the sliding shaft 23 applies a thrust to the limiting plate 26. At this time, the limiting plate 26 starts to rotate under the support of the torsion shaft 27. When the limiting plate 26 rotates and contacts the edge of the limiting groove 22, the edge of the limiting groove 22 blocks the rotation of the limiting plate 26. At this time, the limiting plate 26 stops rotating, and at the same time, the sliding shaft 23 stops sliding. At this time, the rotation of the second fan group 7 is restricted by the sliding shaft 23, and the second fan group 7 stops rotating. At the same time, the screw 5 continues to rotate. At this time, under the rotation of the screw 5, the second fan group 7 starts to move downward. When the second fan group 7 reaches the initial position, the screw 5 stops rotating in the reverse direction. By setting the sliding shaft 23, the second fan group 7 can maintain vertical rotation. At the same time, when it is necessary to move the second fan group 7 downward, it can ensure that the second fan group 7 stops rotating, enabling it to drive the filter plate 4 to operate normally and replace and install the filter plate 4 smoothly, thereby improving the filtering effect and working efficiency of the garbage incineration fly ash filtration and centralized treatment equipment.

[0045] As Figure 1 - Figure 11 shown, the screw 5 is fixedly connected with a one-way bearing 8. One end of the one-way bearing 8 away from the screw 5 is fixedly connected with a connecting shaft 32. The one-way bearing 8 is located inside the filter bin 1. One end of the connecting shaft 32 away from the one-way bearing 8 extends outside the filter bin 1.

[0046] One end of the connecting shaft 32 is fixedly connected with a driven bevel gear 31, the driven bevel gear 31 is meshed and connected with a driving bevel gear 30, a motor 29 is arranged at the lower end of the outer side of the filter bin 1, and the motor 29 is fixedly connected with the driving bevel gear 30.

[0047] When the first fan group 6 starts to rotate, at this time the screw rod 5 starts to rotate. The lower end of the screw rod 5 is fixedly connected with the outer ring of the one-way bearing 8. At this time, the screw rod 5 drives the outer ring of the one-way bearing 8 to start rotating. The inner ring of the one-way bearing 8 is connected with the connecting shaft 32. At this time, the connecting shaft 32 will not follow the screw rod 5 to start rotating. When it is necessary to move the second fan group 7 downward, at this time the motor 29 is started. At this time, the motor 29 drives the driving bevel gear 30 to start rotating. When the driving bevel gear 30 starts to rotate, the driven bevel gear 31 meshed with it starts to rotate. When the driven bevel gear 31 starts to rotate, the driven bevel gear 31 drives the connecting shaft 32 to start rotating. At this time, the connecting shaft 32 drives the one-way bearing 8 to start rotating. At this time, the inner ring of the one-way bearing 8 starts to rotate. The one-way bearing 8 drives the outer ring of the one-way bearing 8 to start rotating. At this time, the one-way bearing 8 drives the screw rod 5 to start rotating. When the screw rod 5 starts to rotate, at this time the second fan group 7 starts to move downward. By arranging the one-way bearing 8, the screw rod 5 remains stationary when rotating forward, and at the same time when it is necessary to reverse the screw rod 5, the screw rod 5 can be reversed, ensuring the normal operation of the filter plate 4, and at the same time ensuring the normal installation of the new filter plate 4, thereby improving the filtering effect and working efficiency of the garbage incineration fly ash filtration and centralized treatment equipment.

[0048] As Figure 1 - Figure 11 As shown in the figure, at least three groups of support blocks 17 are fixedly installed on the lower half of the inner wall of the filter bin 1, and there are two in each group. The support blocks 17 are rotatably connected with a fixed shaft 19.

[0049] A connecting plate 18 is fixedly installed on the outer side of the fixed shaft 19. One end of the connecting plate 18 away from the support block 17 is fixedly installed with a dial plate 3, and a guide strip 16 is fixedly installed at the upper end of the dial plate 3.

[0050] When the first fan group 6 and the second fan group 7 start to rotate, the water inside the filter chamber 1 begins to flow along with them. When the flowing water starts to hit one side of the baffle 3, the edge of the baffle 3 diverts the flowing water to flow to its upper and lower sides. At this time, the water under the baffle 3 flows through the lower side of the baffle 3, and the water flowing through the upper side of the baffle 3 contacts a number of guide strips 16 on the upper side of the baffle 3. The height of the number of guide strips 16 and the intervals between the number of guide strips 16 cause the flowing water to move up and down. Due to the surface tension of the water, the flowing water swings the baffle 3 up and down. When the baffle 3 starts to swing up and down, at this time, the connecting plate 18 follows it to start swinging up and down. At the same time, the fixed shaft 19 starts to rotate under the support of the support block 17 on the inner wall of the filter chamber 1. At this time, the swinging baffle 3 will stir up the fly ash deposited at the lower end of the inner wall of the filter chamber 1 due to the rotation of the flowing water, causing it to move upward and enter the inside of the filter plate 4. By setting the baffle 3, it can stir up the fly ash deposited at the lower end of the inner wall of the filter chamber 1 and make it float into the rotating filter plate 4, ensuring that the fly ash inside the filter chamber 1 can be fully filtered by the filter plate 4, and at the same time avoiding the generation of sludge due to the deposition of fly ash inside the filter chamber 1, which requires regular stopping of garbage incineration and then cleaning, thereby further improving the filtering effect and working efficiency of the garbage incineration fly ash filtering and centralized treatment equipment.

[0051] As Figure 1 - Figure 11 shown, an air flue 2 is fixedly installed on the lower half of the outer side of the filter chamber 1, and the outlet of the air flue 2 is located on one side of the first fan group 6 and the second fan group 7.

[0052] When garbage is incinerated in the incinerator, the high-temperature heat flow generated by combustion drives the fly ash into the air flue 2. At this time, the air flue 2 is divided into two flues outside the filter chamber 1, and at the same time, the sizes of the two flues are different. When the heat flow rushes from the air flue 2 into the filter chamber 1, the heat flow and the fly ash push the first fan group 6 and the second fan group 7, and at this time, the first fan group 6 and the second fan group 7 start to rotate.

[0053] Working principle: The first fan group 6 starts to rotate, the screw rod 5 starts to rotate, the outer ring of the one-way bearing 8 rotates, the connecting shaft 32 does not rotate, the second fan group 7 starts to rotate, the sliding shaft 23 starts to slide, the plug column 14 rotates, the limiting plate 26 rotates, the torsion spring 28 makes a torsion action, the limiting plate 26 enters the inside of the limiting groove 22, the sliding shaft 23 passes through it, the limiting plate 26 starts to rotate, the torsion spring 28 returns to the initial state, the limiting plate 26 returns to the initial state, and at the same time the support column 9 starts to rotate, the filter plate 4 starts to rotate, the second fan group 7 moves upward, the sliding shaft 23 pulls the support plate 10, the support plate 10 pulls the support shaft 11, the support shaft 11 slides upward, the second fan group 7 stops moving upward, the support shaft 11 stops sliding upward, the motor 29 starts, the driving bevel gear 30 starts to rotate, the driven bevel gear 31 starts to rotate, the connecting shaft 32 starts to rotate, the one-way bearing 8 starts to rotate, the screw rod 5 starts to rotate, the second fan group 7 moves downward and rotates at the same time, the sliding shaft 23 slides reversely, when the limiting plate 26 contacts the edge of the limiting groove 22, the limiting plate 26 stops rotating, the sliding shaft 23 stops sliding, the second fan group 7 stops rotating, the screw rod 5 continues to rotate, the second fan group 7 moves downward, when the second fan group 7 reaches the initial position, the screw rod 5 stops reversing, at this time the second fan group 7 starts to rotate, the plug column 14 starts to rotate, the support column 9 starts to slide, the plug column 14 enters the inside of the plug hole 33, the support column 9 starts to rotate, the filter plate 4 starts to rotate, the dial 3 swings up and down, the connecting plate 18 swings up and down, and the fixed shaft 19 starts to rotate.

[0054] The above is only a preferred specific embodiment of the present invention, but 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 and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
